Description

Technical Field

[0001] This utility model relates to the technical field of track slab production equipment, specifically to a multi-functional hoisting device. Background Technology

[0002] Concrete track slabs are the primary support structure for railway tracks in railway transportation systems. The structure of a concrete track slab mainly consists of a reinforcing cage and the concrete covering it. The reinforcing cage is made of steel bars of various types and shapes. After production, the cage is transported to a designated location via a conveyor. Due to the large size of the cages, they often need to be lifted, transported, and stacked on shelves. After the shelves have borne a certain number of cages, they need to be transferred to forklifts or other transport vehicles. To ensure the overall production efficiency of concrete track slabs and the safety of workers, there is an urgent need for a multi-functional lifting device that can reliably support the reinforcing cages and adapt to the lifting of both the cages and the shelves. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a multi-functional hoisting device that can reliably support steel cages and adapt to hoisting steel cages and shelves.

[0004] To solve the above-mentioned technical problems, this utility model includes a conveyor for transporting steel cages. Its structural features include: a clamping mechanism that can be mounted on an external lifting device and a rack for supporting the steel cages. The clamping mechanism includes a lifting ring with several pull ropes attached to it. A mounting frame is attached to the lower part of each pull rope. The mounting frame has several automatic hooks for clamping the steel cages. Each automatic hook includes two hooks that can move closer to or further away from each other, and a drive unit located above the hooks and driving the two hooks. The rack includes a frame body with several detachable, spaced-apart support components for supporting the steel cages. Several ear plates are fixed to the frame body, each ear plate having through holes. The mounting frame has hanging rings that correspond vertically to the ear plates.

[0005] With the above structure, the operator attaches the clamping mechanism to an external lifting device via lifting rings, for example, by attaching the entire clamping mechanism to the hook of an overhead crane via lifting rings. After the conveyor delivers the processed rebar cage, the conveyor pauses its operation. Then, the external lifting device moves the clamping mechanism close to the rebar cage on the conveyor, and the drive unit drives the two hooks to move closer together, thus hooking the rebar in the cage. The external lifting device then moves the clamping mechanism holding the rebar cage away from the conveyor and closer to the rack. The external lifting device then transfers the rebar cage held by the clamping mechanism to the support assembly. The drive unit drives the two hooks to move away from each other, thus releasing the rebar cage, which is then stably supported by the support assembly. Several rebar cages are stacked sequentially from bottom to top on several support assemblies. Once the lower support assembly supports the rebar cage, the operator then installs the upper support assembly onto the frame, thus completing the continuous operation. Once the rack is loaded with a preset number of rebar cages, the clamping mechanism remains close to the rack. Operators can thread chains or wire ropes between the through holes and hanging rings on the ear plates, allowing external lifting equipment to hoist and transfer the rack carrying the rebar cages to a preset location or onto a forklift or other transport vehicle. This ensures reliable support for the rebar cages and adaptability for hoisting both the rebar cages and the rack.

[0006] Furthermore, the support assembly includes several spaced-apart support bars, and the frame is fixedly connected to several bearing seats. Each bearing seat has a downwardly recessed groove whose shape corresponds to the support bar. Each support bar overlaps within the grooves of at least two bearing seats. By configuring the support bars and bearing seats, operators can easily overlap the support bars onto the bearing seats via the grooves, which also provide a limiting function for the support bars. The at least two bearing seats corresponding to one support bar provide stable support for the support bars.

[0007] Furthermore, the mounting frame includes several guide rods extending downwards with their bottom ends located below the bottom of the mounting frame. It also includes several guide seats distributed near the conveyor, each corresponding to one of the guide rods. Each guide seat has a guide hole for the guide rod to pass through. By providing guide rods and guide seats, as the clamping mechanism approaches the conveyor from top to bottom, the guide rods and guide seats guide the vertical movement of the clamping mechanism, ensuring that the automatic hook can stably and accurately clamp the steel cage at the preset position, preventing the clamping mechanism from shaking and causing collisions or interference between the automatic hook and the steel cage.

[0008] Furthermore, the bottom of the guide rod is provided with an alignment end, the outer diameter of which gradually increases from bottom to top, and the maximum outer diameter of the alignment end is adapted to the outer diameter of the guide rod. By providing the alignment end, the movement of the guide rod can be guided when it passes through the guide hole from top to bottom, preventing interference between the edge of the guide rod and the guide hole, and ensuring the stability and accuracy of the guide rod's movement.

[0009] Furthermore, the guide hole includes a first hole and a second hole located above the first hole. The diameter of the first hole is adapted to the outer diameter of the guide rod, and the diameter of the second hole gradually increases from bottom to top. By setting the first hole and the second hole, the second hole can stably support the guide rod and provide guidance for the movement of the guide rod when it passes through the guide hole from top to bottom, preventing interference between the edge of the guide rod and the top edge of the guide hole, and ensuring the stability and accuracy of the guide rod's movement.

[0010] Furthermore, the hook body includes a mounting portion connected to the driving body. The mounting portion has a downwardly extending clearance portion, and the bottom of the clearance portion has a horizontally extending bent portion. One of the hook bodies has a locking protrusion on its bent portion, and the other hook body has an alignment groove corresponding to the locking protrusion on its bent portion. By providing the mounting portion, clearance portion, and bent portion, the clearance portion ensures sufficient clearance between the rebar cage and the mounting portion, preventing interference between them. When the two hook bodies approach each other, the top surfaces of the bent portions of both hook bodies can jointly hook the rebar on the rebar cage, ensuring stable load-bearing capacity. By providing the locking protrusion and alignment groove, the locking protrusion can extend into the alignment groove when the bent portions of the two hook bodies approach each other, ensuring the positional accuracy of the bent portions when they approach each other.

[0011] Furthermore, the bottom of the mounting frame is equipped with several stop brackets. After two hooks approach each other and hook the rebar cage, the bottom of the stop bracket is located between the top of the rebar cage and the bottom of the drive body. By setting the stop brackets, the clamping mechanism is prevented from moving down excessively, which could cause the drive body to collide and interfere with the rebar cage, thus ensuring the integrity of the automatic hook.

[0012] In summary, this utility model has the advantages of reasonable structure and convenient use. Attached Figure Description

[0015] Reference Figures 1 to 5 and Figure 13This utility model includes a conveyor 1 for conveying steel cages. The conveyor 1 can be a commonly available chain conveyor belt, and the conveyor 1 delivers the steel cages from front to back. This utility model also includes a clamping mechanism 2 that can be mounted on an external lifting device and a rack 3 for supporting the steel cages. The external lifting device can be a manually controlled overhead crane or an automatic overhead crane. The clamping mechanism 2 includes a lifting ring 21, on which several pull ropes 22 are hung. The pull ropes 22 can be steel wire ropes or iron chains. A mounting frame 23 is hung on the lower part of the pull ropes 22. A connecting ring that can be mounted inside the lifting ring 21 is provided on the upper part of the pull ropes 22. An iron hook is provided on the lower part of the pull ropes 22. The mounting frame 23 has a ring seat that can cooperate with the iron hook of the pull rope 22 and can rotate freely. The iron hook of the pull rope 22 is mounted inside the ring seat.

[0016] Reference Figures 1 to 6 and Figure 13 The mounting frame 23 is equipped with several automatic hooks 24 for hooking the rebar cage. Each automatic hook 24 includes two hooks 241 that can move closer together and further apart, and a drive unit 242 located above the hooks 241 and driving the two hooks 241. The drive unit 242 is connected to the mounting frame 23 by fasteners. The drive unit 242 can be a commercially available electric module, which can be a motor-driven single-gear double-rack type or a motor-driven forward and reverse screw nut type. The mounting frame 23 may be equipped with several battery packs to provide power to the drive unit 242. Each hook 241 includes a mounting portion 2411 connected to the drive unit 242. The mounting portion 2411 has a downwardly extending clearance portion 2412, and the bottom of the clearance portion 2412 has a horizontally extending bend portion 2413. The bend portions 2413 of the two hooks 241 extend in opposite directions, and both hooks 241 are approximately L-shaped. One of the two hooks 241 has a locking protrusion 6 on its bent portion 2413, and the other hook 241 has an alignment groove 24131 corresponding to the locking protrusion 6 on its bent portion 2413. The clearance portion 2412 ensures sufficient clearance between the reinforcing cage and the mounting portion 2411, preventing interference between them. When the two hooks 241 approach each other, the top surfaces of the bent portions 2413 of both hooks 241 can jointly hook the reinforcing bars on the reinforcing cage, ensuring stable load-bearing capacity. By providing the locking protrusion 6 and the alignment groove 24131, the locking protrusion 6 can extend into the alignment groove 24131 when the bent portions 2413 of the two hooks 241 approach each other, ensuring the positional accuracy of the bent portions 2413 when they approach each other. The bending part 2413 extends horizontally to the left or right or horizontally to the front and back according to the actual structure of the steel cage, thereby driving the body 241 to move the two hooks 241 closer and further apart in the horizontal direction to the left or right or horizontal direction to hook the steel bars extending in the front and back or horizontally to the left and right of the steel cage.

[0017] Reference Figure 1 , Figure 3, Figures 7 to 10 The shelving unit 3 includes a frame 31, which has several detachable, spaced-apart support components 32 for supporting the reinforcing cage. The frame 31 is fixedly connected to several ear plates 311, each with a through hole 3111. The mounting frame 23 has hanging rings 231 that correspond vertically to the ear plates 311. Each support component 32 includes several spaced-apart support bars 321. The frame 31 is fixedly connected to several bearing seats 322, each bearing seat 322 having a downwardly recessed groove 3221 whose shape matches the support bars 321. Each support bar 321 overlaps within the grooves 3221 of at least two bearing seats 322. The bearing seats 322 are made of metal plates and fixedly welded to the frame 31. The support bars 321 can be made of square tubing. In this embodiment, one support component 32 includes three spaced-apart support bars 321, and each pair of spaced-apart bearing seats 322 supports one support bar 321. Workers can easily attach the support bar 321 to the support seat 322 via the slot 3221, which also provides a limiting function for the support bar 321. At least two support seats 322 are correspondingly set with one support bar 321, which can provide stable support for the support bar 321.

[0018] Reference Figures 1 to 5 and Figures 11 to 13The mounting frame 23 is provided with several guide rods 4, which extend downwards and whose bottom ends are located below the bottom end of the mounting frame 23. This invention also includes several guide seats 5, which are distributed near the conveyor 1. Each guide seat 5 corresponds to one of the guide rods 4, and each guide seat 5 has a guide hole 51 for inserting the guide rod 4. Both the conveyor 1 and the guide seats 5 can be anchored to the workshop floor using fasteners. In this embodiment, four guide rods 4 and four guide seats 5 are provided, distributed in pairs on the left and right sides of the conveyor 1, forming a quadrilateral. When the clamping mechanism 2 approaches the conveyor 1 from top to bottom, the guide rods 4 and guide seats 5 provide guidance for the vertical movement of the clamping mechanism 2, ensuring that the automatic hook 24 can stably and accurately clamp the steel cage at the preset position, preventing the clamping mechanism 2 from shaking and causing the automatic hook 24 to collide and interfere with the steel cage. Preferably, the guide rod 4 has an alignment end 41 at its bottom, the outer diameter of which gradually increases from bottom to top, and the maximum outer diameter of the alignment end 41 is adapted to the outer diameter of the guide rod 4. By setting the alignment end 41, the movement of the guide rod 4 can be guided when it passes through the guide hole 51 from top to bottom, preventing interference between the edge of the guide rod 4 and the guide hole 51, and ensuring the stability and accuracy of the guide rod 4 during movement. Preferably, the guide hole 51 includes a first hole body 511 and a second hole body 512 located above the first hole body 511. The diameter of the first hole body 511 is adapted to the outer diameter of the guide rod 4, and the diameter of the second hole body 512 gradually increases from bottom to top. The minimum diameter of the second hole body 512 is adapted to the diameter of the first hole body 511, and the diameter of the first hole body 511 is slightly larger than the outer diameter of the guide rod 4. The second hole 512 can stably support the guide rod 4 and provide guidance for the movement of the guide rod 4 when it passes through the guide hole 51 from top to bottom. This prevents the edge of the guide rod 4 from interfering with the top edge of the guide hole 51, ensuring the stability and accuracy of the guide rod 4 during movement, and thus ensuring that the clamping mechanism 2 accurately hooks the steel cage on the conveyor 1.

[0019] Reference Figure 1 , Figure 4 and Figure 13 Preferably, the bottom of the mounting frame 23 is provided with several stop brackets 7. After the two hooks 241 approach each other and hook the rebar cage, the bottom of the stop brackets 7 is located between the top of the rebar cage and the bottom of the drive body 242. By setting the stop brackets 7, the clamping mechanism 2 is prevented from moving down too far, causing the drive body 242 to collide and interfere with the rebar cage, thus ensuring the integrity of the automatic hook 24. That is, when the clamping mechanism 2 moves down too far, the stop brackets 7 rest against the rebar cage, at which time the drive body 242 and the top of the rebar cage have a clearance distance in the vertical direction.

[0020] In use, the operator attaches the clamping mechanism 2 to an external lifting device via the lifting ring 21. For example, the clamping mechanism 2 can be entirely attached to the hook of an overhead crane via the lifting ring 21. After the conveyor 1 delivers the processed rebar cage, the conveyor 1 pauses its transport. Then, the external lifting device moves the clamping mechanism 2 close to the rebar cage on the conveyor 1. The drive body 242 drives the two hooks 241 to move closer together, thus hooking the rebar in the cage. The external lifting device moves the clamping mechanism 2, holding the rebar cage, away from the conveyor 1 and closer to the rack 3. The external lifting device then transfers the rebar cage held by the clamping mechanism 2 to the support assembly 32. The drive body 242 drives the two hooks 241 to move away from each other, thus releasing the rebar cage, which can then be stably supported by the support assembly 32. Several rebar cages are stacked sequentially from bottom to top on several support assemblies 32. After the lower support assembly 32 supports the rebar cage, the operator then installs the upper support assembly 32 onto the rack 31, thus completing continuous operation. Once the rack 3 carries a preset number of rebar cages, the clamping mechanism 2 remains close to the rack 3. Operators can thread chains or wire ropes between the through holes 3111 and the hanging rings 231 of the ear plates 311, allowing external lifting equipment to hoist and transfer the rack 3 carrying the rebar cages to a preset location or onto a forklift or other transport vehicle. This ensures reliable support for the rebar cages and adaptability to the hoisting of both the rebar cages and the rack 3.

[0021] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims of this patent, they should all fall within the protection scope of this utility model.
