[0002] An electric hoist is a lifting device widely used in industrial production, construction, logistics and transportation. The drum is one of the key components of an electric hoist, used to reduce motor speed and increase torque, thereby driving the drum to achieve the lifting function.

[0003] In the existing technology, traditional gearboxes are installed at the bottom of electric hoists by brackets or fixing plates, but they are usually reinforced by bolts. However, electric hoists will vibrate during operation, and these vibrations may cause the bolts to gradually loosen. Once the bolts loosen, the stability of the gearbox will decrease.

[0004] Therefore, this utility model provides a reinforcement device for an electric hoist. Utility Model Content

[0005] To address the shortcomings of existing technology and solve the problem that traditional gearboxes are mounted on the bottom of electric hoists via brackets or mounting plates, but are generally only reinforced by bolts, the electric hoist will vibrate during operation. This vibration may cause the bolts to gradually loosen, and once the bolts loosen, the stability of the gearbox will decrease.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A reinforcing device for an electric hoist, comprising an electric hoist body, a fixing plate fixedly connected to the bottom of the electric hoist body, and a reinforcing mechanism provided at the bottom of the fixing plate, the reinforcing mechanism comprising:

[0007] The support assembly includes a pair of rectangular plates fixed to the bottom of a fixed plate. The side walls of the rectangular plates are provided with a pair of sliding grooves. Sliding blocks are slidably connected in the sliding grooves. A locking rod is fixed to the side wall of the sliding block. An adjustment assembly for adjusting the position of the sliding blocks is provided on the pair of rectangular plates.

[0008] The housing assembly is located at the bottom of the fixed plate.

[0009] Preferably, the housing assembly includes a pair of half-shells, each half-shell being connected to the bottom of the fixing plate by a pair of bolts, and the pair of half-shells being arranged opposite to each other.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 4 As shown in the embodiment of this utility model, a reinforcement device for an electric hoist includes an electric hoist body 1, a fixing plate 2 fixedly connected to the bottom of the electric hoist body 1, and a reinforcement mechanism provided at the bottom of the fixing plate 2. The reinforcement mechanism includes: a support assembly, including a pair of rectangular plates 3 fixedly connected to the bottom of the fixing plate 2, a pair of sliding grooves 4 opened on the side wall of the rectangular plates 3, a sliding block 5 slidably connected in the sliding groove 4, a locking rod 6 fixedly connected to the side wall of the sliding block 5, and an adjustment assembly for adjusting the position of the sliding block 5 provided on the pair of rectangular plates 3; and a gearbox assembly, located at the bottom of the fixing plate 2. During operation, the locking rod 6 can be moved by the adjustment assembly, thereby enabling a set of locking rods 6 to reinforce the gearbox. This avoids the problem in the prior art where the traditional gearbox is installed at the bottom of the electric hoist by a bracket or fixing plate 2, but is generally only reinforced by bolt fixing. However, the electric hoist will vibrate during operation, and these vibrations may cause the bolts to gradually loosen. Once the bolts loosen, the stability of the gearbox will decrease.

[0025] The housing assembly includes a pair of half-shells 7, each half-shell 7 is connected to the bottom of the fixing plate 2 by a pair of bolts, and the pair of half-shells 7 are arranged opposite each other. A pair of locking grooves 8 and a pair of rectangular grooves 9 are opened on the side wall of the half-shell 7. Magnetic blocks 10 are fixed in the rectangular grooves 9. During operation, the gearbox is connected to the pair of half-shells 7 through the set gearbox assembly and can be docked by a set of magnetic blocks 10. Each half-shell 7 is fixed to the bottom of the fixing plate 2 by a pair of bolts. This allows the gearbox to be easily opened for maintenance by the staff. At the same time, when the locking rod 6 is locked in the locking groove 8 to reinforce the gearbox, it can clamp the pair of half-shells 7 and prevent them from separating.

[0026] The adjustment assembly includes a pair of gears 11 rotatably connected to the side wall of a rectangular plate 3 via a pair of first rotating shafts. A fixed rod 12 is fixedly connected to the side wall of the gears 11. One end of the fixed rod 12 is rotatably connected to an adjusting rod 13 via a second rotating shaft. During operation, a connecting rod 14 is rotatably connected to the side wall of the adjusting rod 13 via a third rotating shaft. One end of the connecting rod 14 is rotatably connected to the side wall of the rectangular plate 3 via a fourth rotating shaft. An adjusting block 15 is fixedly connected to the side wall of a sliding block 5. An adjusting hole 16 is provided on the adjusting block 15. The bottom end of the adjusting rod 13 is slidably connected to the adjusting hole 16. A moving groove 17 is provided on the rectangular plate 3. A moving block 18 is slidably connected to the moving groove 17. A rack 19 is fixedly connected to the side wall of the moving block 18. The rack 19 meshes with a pair of gears 11 on both sides. The side wall of the rectangular plate 3 is connected to the gears 11 via a second rotating shaft. An electric actuator 20 is fixedly connected to a fixed block. The telescopic end of the electric actuator 20 is fixedly connected to the bottom of the rack 19. During operation, the electric actuator 20 drives the rack 19 to move up and down. This movement of the rack 19 drives a pair of gears 11 meshing with the rack 19 to rotate, which in turn causes the fixed rod 12 to rotate. The other end of the fixed rod 12 then drives the connected adjusting rod 13 and connecting rod 14 to rotate. As the adjusting rod 13 moves, it drives the adjusting block 15 to move. This, in turn, drives the locking rod 6 to move via the sliding block 5, allowing it to lock into the locking groove 8 for reinforcement. By using a set of locking rods 6 to lock the four corners of the gearbox, the gearbox's stability is improved.

[0027] Working Principle: The adjustable components move the locking rods 6, allowing the locking rods 6 to reinforce the gearbox. This avoids the problem of traditional gearboxes being mounted on the bottom of the electric hoist via brackets or fixing plates 2, typically secured with bolts. However, the vibrations generated during hoist operation can loosen these bolts, reducing gearbox stability. The gearbox, connected to a pair of half-shell assemblies 7 and magnetic blocks 10, is secured to the bottom of the fixing plate 2 with bolts. This allows for easy access and maintenance during repairs. Furthermore, the locking rods 6 secure the gearbox. Within the locking slot 8, when reinforcing the gearbox, the pair of half-shells 7 can be clamped to prevent them from separating. Driven by the electric push rod 20, the rack 19 can be moved up and down, which in turn drives the pair of gears 11 meshing with the rack 19 to rotate, thereby causing the fixing rod 12 to rotate. The other end of the fixing rod 12 can drive the connected adjusting rod 13 and connecting rod 14 to rotate, so that the bottom end of the adjusting rod 13 can drive the adjusting block 15 to move during the movement. This, in turn, drives the locking rod 6 to move through the sliding block 5, allowing it to be locked in the locking slot 8 for reinforcement. By using a set of locking rods 6 to lock the four corners of the gearbox, the stability of the gearbox can be improved.
