A Suspension Axle Lifting Device

Technical Field

The utility model relates to a lifting device, in particular to a suspension axle lifting device, belonging to the technical field of axle processing.

Background Technology

An axle, also known as a vehicle axle, is a very important component in an automobile running system. It is connected to the frame through the suspension, and wheels are mounted at both ends. Its function is to bear the load of the vehicle and maintain normal driving of the vehicle on the road.

During maintenance of a suspension axle, it is often necessary to raise its height. Common lifting devices are inconvenient for placing and removing the suspension axle. In addition, when lifting the suspension axle, common lifting devices have poor stability, and the suspension axle is prone to tilting.

Utility Model Content

The purpose of the utility model is to provide a suspension axle lifting device, so as to solve the problem that common lifting devices have poor stability when lifting a suspension axle, causing the suspension axle to tilt easily.

To achieve the above purpose, the utility model provides the following technical solution:

A suspension axle lifting device comprises a frame. Mounting mechanisms are fixedly arranged at the top and bottom portions of both sides of the frame. A forward-reverse motor and a backing plate are respectively fixedly arranged on two side edges of the top end of the frame.

The transmission shaft of the forward-reverse motor is fixedly connected to one end of a rope winding mechanism through a coupling. The other end of the rope winding mechanism is rotatably connected to one side of the backing plate through a mounted bearing.

The rope winding mechanism is fixedly connected to one end of two steel wire ropes. The rope winding mechanism comprises a rotating shaft, two winding drums, and four baffles.

One end of the rotating shaft is fixedly connected to the rotating shaft of the forward-reverse motor through the coupling, and the other end of the rotating shaft is rotatably connected to one side of the backing plate through the mounted bearing.

Two winding drums are fixedly arranged on the surface of the rotating shaft, and baffles are fixedly arranged on both sides of each winding drum. One side of each winding drum is respectively fixedly connected to the other end of each steel wire rope.

The other ends of the two steel wire ropes are respectively fixedly connected to both sides of the top end of a lifting plate through lifting lugs. Vertical plates are fixedly arranged on both sides of the bottom end of the lifting plate. Placement plates are fixedly arranged at the lower portions of the front sides of the two vertical plates. Placement grooves are formed in the top ends of the two placement plates.

Gear discs are rotatably connected to both ends of the lifting plate. Racks are fixedly arranged on the inner walls of both sides of the frame, and the two racks are respectively meshed with the two gear discs.

Preferred Technical Solutions

The four mounting mechanisms each comprise a welding plate, a mounting plate, and four mounting holes. One side of each welding plate is respectively welded to the top and bottom portions of both sides of the frame, and the other side of each welding plate is welded with a mounting plate. Four mounting holes are formed in the surface of each mounting plate.

Limit holes are formed on both sides of the top end of the frame, and the two steel wire ropes are respectively inserted through the two limit holes.

The two limit holes are respectively aligned with the two lifting lugs, and copper sleeves are fixedly arranged on the inner walls of the two limit holes.

Two limit plates are fixedly arranged on one side of each rack, and hardened layers are fixedly arranged on the surfaces of the limit plates.

A forward-reverse motor switch is fixedly arranged on one side of the front face of the frame. The forward-reverse motor is electrically connected to a power supply through the forward-reverse motor switch.

Beneficial Effects

Compared with the prior art, the utility model has the following beneficial effects:

By forming placement grooves on the top ends of the two placement plates, the two placement grooves can support and limit both sides of the suspension axle, thereby maintaining the stability of the suspension axle.

By fixing the two placement plates respectively at the lower portions of the front sides of the two vertical plates, the placement plates protrude from the frame, providing operating space and making it convenient to place and remove the suspension axle.

By connecting one end of each steel wire rope to the winding drum of the rope winding mechanism, and connecting the other end of each steel wire rope to both sides of the top end of the lifting plate through lifting lugs, both sides of the lifting plate can be pulled tightly, so that the lifting plate is not prone to tilting.

When the forward-reverse motor drives the rope winding mechanism to rotate, the gear discs at both ends of the lifting plate respectively mesh with the two racks, thereby improving the stability of the lifting plate and preventing the suspension axle from tilting.

Specific Embodiment

Please refer to Figures 1–3. The utility model provides a suspension axle lifting device, comprising a frame 1. Mounting mechanisms 2 are fixedly arranged at the top and bottom portions of both sides of the frame 1. A forward-reverse motor 3 and a backing plate 6 are respectively fixedly arranged on two side edges of the top end of the frame 1.

The transmission shaft of the forward-reverse motor 3 is fixedly connected to one end of the rope winding mechanism 5 through a coupling 4. The other end of the rope winding mechanism 5 is rotatably connected to one side of the backing plate 6 through a mounted bearing 7.

The rope winding mechanism 5 is fixedly connected to one end of two steel wire ropes 8. The rope winding mechanism 5 comprises a rotating shaft 501, two winding drums 502, and four baffles 503.

One end of the rotating shaft 501 is fixedly connected to the rotating shaft of the forward-reverse motor 3 through the coupling 4, and the other end of the rotating shaft 501 is rotatably connected to one side of the backing plate 6 through the mounted bearing 7.

Two winding drums 502 are fixedly arranged on the surface of the rotating shaft 501. Baffles 503 are fixedly arranged on both sides of each winding drum 502. One side of each winding drum 502 is respectively fixedly connected to the other end of each steel wire rope 8.

The other ends of the two steel wire ropes 8 are respectively fixedly connected to both sides of the top end of the lifting plate 10 through lifting lugs 9. Vertical plates 11 are fixedly arranged on both sides of the bottom end of the lifting plate 10. Placement plates 12 are fixedly arranged at the lower portions of the front sides of the two vertical plates 11. Placement grooves 13 are formed in the top ends of the two placement plates 12.

Gear discs 14 are rotatably connected to both ends of the lifting plate 10. Racks 15 are fixedly arranged on the inner walls of both sides of the frame 1. The two racks 15 are respectively meshed with the two gear discs 14.

When the device is used for maintaining a suspension axle, if the height of the suspension axle needs to be raised, both sides of the suspension axle are first placed into the placement grooves 13 on the two placement plates 12. The two placement grooves 13 limit both sides of the suspension axle and maintain its stability.

Then, the forward-reverse motor 3, which may be model PL22-0100, drives the rope winding mechanism 5 to rotate in one direction. The two winding drums 502 of the rope winding mechanism 5 wind the steel wire ropes 8, thereby driving the lifting plate 10 upward and raising the height of the suspension axle.

The gear discs 14 at both ends of the lifting plate 10 are respectively meshed with the two racks 15, thereby improving the stability of the lifting plate 10 and preventing the suspension axle from tilting during maintenance.

After maintenance is completed, the forward-reverse motor 3 drives the rope winding mechanism 5 to rotate in the opposite direction. The two winding drums 502 of the rope winding mechanism 5 release the steel wire ropes 8, thereby driving the lifting plate 10 downward and lowering the height of the suspension axle. The suspension axle can then be removed from the two placement grooves 13.
