[0001] The invention belongs to the technical field of hoisting devices, and in particular relates to a novel hoisting device dedicated for assembling a railway train engine. Background Art

[0002] The new rail train engine is an advanced power device that provides power for modern rail transit systems. It is usually used for high-speed, heavy-load or high-efficiency rail trains. It combines the latest electric drive technology, intelligent control systems and high-efficiency power systems to improve the running speed, stability and energy efficiency of the train. The new rail train engine is usually powered by electricity and integrates advanced frequency conversion control, brushless motor technology, etc., with the ability of rapid response and precise control.

[0003] When assembling new rail train engines in the prior art, special lifting devices are usually required due to the large size of the engines. The engines are often required to be slowly and accurately moved downward to a specified position through the cooperation of slings and hooks. However, existing lifting devices are generally unable to effectively limit the position of the hoisted engines, causing the engines to shake easily during movement, which not only increases the difficulty of assembly, but may also cause the engine to collide or scratch the installation area, thereby causing irreversible damage to the engine and seriously affecting the assembly quality.

[0004] To this end, we provide a new type of special lifting device for railway train engine assembly to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a new type of lifting device specially used for assembling railway train engines. By cooperating with a lifting component and a self-locking component, the problem of the new type of railway train engines in the prior art that the lifting device cannot effectively limit the moving engine during assembly, thus affecting the assembly of the engine, is solved.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The sprocket wheel is connected with the support frame by the spring, and the steering wheel is fixed on the support frame, and the steering wheel is turned on the support frame, and the steering wheel is turned on the support frame.

[0008] The present invention is further configured such that a transmission rod is movably connected to the inner cavity of the support frame, one end of the transmission rod is fixedly connected to a driving bevel gear, one side of the retractable roller surface is fixedly connected to a driven bevel gear, and the driving bevel gear is meshed with the driven bevel gear.

[0009] The present invention is further configured such that a toothed plate is fixedly connected to the top of the placing table, rotating gears are fixedly connected to both sides of the surface of the rotating rod, and the rotating gears are meshed with the toothed plate.

[0010] The present invention is further configured such that a second cylinder is fixedly connected to one side of the inner cavity of the base, a fixed block is fixedly connected to the free end of the second cylinder, a motor is fixedly connected to the inner cavity of the fixed block, a drive rod is fixedly connected to the output end of the motor, and a first gear is fixedly connected to one side of the surface of the drive rod.

[0011] The present invention is further configured such that a driving gear is fixedly connected to one side of the surface of the driving rod, and a driven gear is fixedly connected to one side of the surface of the bidirectional lead screw, and the driving gear is meshed with the driven gear.

[0012] The present invention is further configured such that a second gear is fixedly connected to one side of the surface of the transmission rod, and the second gear is meshed with the first gear.

[0013] The present invention is further configured such that a sliding frame is fixedly connected to one side of the inner cavity of the base, a supporting block is slidably connected to the inner cavity of the sliding frame, and one side of the supporting block is movably connected to one end of the driving rod.

[0014] The present invention is further configured such that both sides of the fixed block are fixedly connected with vertical plates, and one side of the vertical plate is movably connected with a roller.

[0015] The present invention is further configured such that a limiting hole is provided on one side of the surface of the transmission rod, and an inner cavity of the limiting hole is slidably connected to one end of the insertion rod.

[0016] The present invention is further configured such that a sling is wound around the surface of the drum, and one end of the sling is fixedly connected to a hook.

[0017] The present invention has the following beneficial effects.

[0018] 1. The present invention drives the active gear and the driven gear meshing on the surface of the driving rod to rotate through a motor drive, so that the two sliding sleeves drive the placement table to move in opposite directions, open the placement opening of the inner cavity of the base, and provide convenient conditions for subsequently hoisting the engine to the required area. At the same time, the movement of the placement table drives the rotating gear to rotate through the toothed plate on its surface, and then the limit plate on the surface of the rotating rod rotates, thereby achieving precise positioning of the engine, effectively limiting the shaking of the engine during the hoisting process, and avoiding collision or scratching with the installation area due to shaking.

[0019] 2. The present invention realizes the movement of the motor in the inner cavity of the fixed block by driving the second cylinder, thereby driving the first gear on the surface of the driving rod to engage with the second gear. Under the drive of the motor, the first gear and the second gear interact with each other to drive the transmission rod to rotate. One end of the transmission rod is connected to an active bevel gear, which engages with the driven bevel gear on the surface of the reel, thereby driving the reel to rotate and causing the cable on the surface of the drum to move accordingly, thereby realizing the precise movement of the engine and moving it to the desired assembly position.

[0020] 3. The present invention releases the extrusion of the rollers on both sides of the fixed block and one side of the inclined block, and utilizes the elastic effect of the tension spring to make the inclined block slide along the surface of the vertical rod. The limit clamp on one side of the inclined block clamps the bidirectional lead screw in this process, so that when the driving gear and the driven gear are not engaged, the bidirectional lead screw is limited. The first cylinder drives the insertion rod to move so that one end of the insertion rod extends into the limiting hole of the transmission rod. The insertion rod can effectively limit the transmission rod, ensuring that when the first gear and the second gear are not engaged, the transmission rod is also accurately limited.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The base 1 is fixedly connected to the surface, and both sides of the top of the base 1 are movably connected with rotating rods 8, and the surface of the rotating rod 8 is fixedly connected to a limit plate 9; a self-locking component is provided in the inner cavity of the base 1, and the self-locking component includes a vertical rod 10, and the vertical rod 10 is fixedly connected to one side of the inner cavity of the base 1, and both sides of the surface of the vertical rod 10 are slidably connected with inclined blocks 11, and the surface of the vertical rod 10 is sleeved with a tension spring 12, and one side of the inclined block 11 is fixedly connected to a limit clamp 13, and one side of the inner cavity of the base 1 is fixedly connected to a first cylinder 14, and the free end of the first cylinder 14 is fixedly connected to an insertion rod 15.

[0034] Specifically: both sides of the support frame 2 are fixedly connected with a cable, one end of the cable is fixed to the top of the base 1, so as to improve the stability of the support frame 2, a sliding rod is fixedly connected to one side of the inner cavity of the base 1, and a slider is slidably connected to the surface of the sliding rod. One side of the sliding rod is fixed to one side of the placement table 6, which can limit the sliding sleeve 5 and support the placement table 6. The bottom side of the placement table 6 slides with the inner cavity of the base 1, which can support one side of the placement table 6 to ensure that the placement table 6 can slide normally. Both ends of the rotating rod 8 are movably connected with a fixed shaft, the bottom of the fixed shaft is fixed to the top of the base 1, and the bottom of the base 1 is movably connected with a self-locking wheel, which can improve the portability of the lifting device. The self-locking wheels improve the convenience of the device and also have a locking function, which can effectively prevent the device from moving during use and ensure the stability and safety of the equipment.

[0035] The two ends of the vertical rod 10 are respectively fixed to the two sides of the inner cavity of the base 1, and the two ends of the tension spring 12 are respectively fixed to one side of the two inclined blocks 11. Since the transmission rod 16 is used to drive the reel 3 on the surface of the retractable roller 7 to rotate, and the engine will be hoisted at the bottom of the hook 32, the first cylinder 14 drives the insertion rod 15 to limit the transmission rod 16, which can ensure the stability of the transmission rod 16 when the second gear 28 on the surface of the transmission rod 16 is not engaged with the first gear 25 on the surface of the transmission rod 16.

[0036] Embodiment 2

[0037] See also Figure 1-7 On the basis of the first embodiment, a transmission rod 16 is movably connected to the inner cavity of the support frame 2, and a driving bevel gear 17 is fixedly connected to one end of the transmission rod 16.

[0038] Specifically: one end of the transmission rod 16 extends to the inner cavity of the base 1, so that the active bevel gear 17 can mesh with the driven bevel gear 18, and sliding grooves are provided on both sides of the top of the base 1 to enable the tooth plate 19 to move normally. A placement opening is provided in the inner cavity of the base 1, and the placement table 6 slides in the placement opening. One end of the second cylinder 21 is fixed to one side of the inner cavity of the base 1, and the bottom of the fixed block 22 slides with one side of the bottom of the base 1 to ensure that the motor 23 can move normally. The teeth on the surfaces of the first gear 25 and the second gear 28 are both beveled and can mesh, and the meshing method of the two can be called a cross-axis bevel gear.

[0039] Embodiment 3

[0040] See also Figure 1-7 On the basis of the first embodiment, a second gear 28 is fixedly connected to one side of the surface of the transmission rod 16, and the second gear 28 is meshed with the first gear 25. A sliding frame 29 is fixedly connected to one side of the inner cavity of the base 1, and a support block is slidably connected to the inner cavity of the sliding frame 29. One side of the support block is movably connected to one end of the driving rod 24.

A limiting hole is opened on one side of the surface of the transmission rod 16, and the inner cavity of the limiting hole is slidably connected to one end of the insertion rod 15. A sling 31 is wound around the surface of the reel 3, and a hook 32 is fixedly connected to one end of the sling 31.

[0041] Specifically: the sliding frame 29 can limit the support block, the support block can support the driving rod 24, the roller 30 squeezes the inclined block 11 to release the limit of the bidirectional screw 4 by the limit clamp 13, and it is convenient for the motor 23 to drive the bidirectional screw 4 to rotate, and the limit hole can limit the transmission rod 16 when the insertion rod 15 is inserted to prevent the transmission rod 16 from automatically rotating and affecting the lifting, and the sling 31 and hook 32 on the surface of the drum 3 can lift the engine.

[0042] The working principle of the present invention is as follows: when it is necessary to assemble a new type of rail train engine, first place the required engine on the surface of the placement table 6 in the base 1, then connect the engine to the hook 32, and then drive the drive rod 24 to rotate through the motor 23, the drive rod 24 drives the first gear 25 to rotate, the first gear 25 drives the second gear 28 to rotate, the second gear 28 drives the transmission rod 16 to rotate, the transmission rod 16 drives the active bevel gear 17 to rotate, the active bevel gear 17 drives the driven bevel gear 18 to rotate, the driven bevel gear 18 drives the reel 7 to rotate, the reel 7 drives the reel 3 to rotate, the reel 3 tightens the sling 31, so that the engine is separated from the top of the placement table 6.

[0043] Then, the first cylinder 14 is started through the external controller, and the first cylinder 14 drives the insertion rod 15 to move. One end of the insertion rod 15 extends into the limiting hole of the transmission rod 16, so as to limit the transmission rod 16 and ensure the stability of the engine. Then, the second cylinder 21 is started through the external controller, and the second cylinder 21 drives the fixed block 22 to move, and the fixed block 22 drives the motor 23 to move, and the motor 23 drives the driving rod 24 to move. When the fixed block 22 moves, the roller 30 and the inclined block 11 are squeezed, so that the inclined block 11 moves to both sides of the surface of the vertical rod 10, thereby driving the limiting clamp 13 to release the limit of the bidirectional screw 4, and at the same time, the driving gear 26 is engaged with the driven gear 27.

[0044] At this time, the motor 23 can be started through the external controller. When the motor 23 works to drive the driving rod 24 to rotate, the meshing active gear 26 and the driven gear 27 can be rotated, thereby driving the bidirectional screw 4 to rotate. The bidirectional screw 4 drives the two sliding sleeves 5 on its surface to move in opposite directions. The sliding sleeves 5 drive the placement table 6 to move and open the placement opening of the inner cavity of the base 1. At the same time, the movement of the placement table 6 drives the rotating gear 20 to rotate through the toothed plate 19 on its surface, and then the limit plate 9 on the surface of the rotating rod 8 rotates, thereby realizing precise limiting of the engine position.

[0045] Finally, the second cylinder 21 is started by the external controller to move the motor 23 back to the transmission rod 16, so that the first gear 25 and the second gear 28 are re-engaged. During the movement, the roller 30 is separated from the inclined block 11, and the inclined block 11 is moved by the elasticity of the tension spring 12. The limit clamp 13 re-limits the bidirectional lead screw 4. After the first gear 25 and the second gear 28 are engaged, the first cylinder 14 is used to separate the insertion rod 15 from the limiting hole. The motor 23 is driven to move the engine at the bottom of the hook 32, so that the engine can be moved to the desired assembly position.
