Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, and in particular to a foldable cable chain hoisting machine. Background Technology

[0002] In various lifting equipment (such as lifting platforms in automated warehouses and material lifting mechanisms on production lines), reliable follow-up protection of cables, hydraulic hoses, or pneumatic pipelines (collectively referred to as "pipelines") is crucial. Cable chains (also known as cable protection chains or tank chains) have become the most commonly used solution in such applications due to their excellent guiding, protective, and abrasion-resistant properties.

[0003] Cable chains, through their articulated links, smoothly bend during equipment lifting and lowering, guiding pipelines to move in an orderly manner. However, traditional cable chains have a significant drawback in lifting equipment: whether in a high lifting position (folded state) or a lowered position (extended state), the cable chain system typically occupies a fixed bending space or remains in its extended state. This means that even when the equipment is in the folded state, the cable chain still requires a large vertical space. In height-restricted installation environments or situations with strict space requirements for the folded state, this "ineffective" space occupied by traditional cable chains has become a bottleneck restricting the miniaturization, compactness, and site adaptability of equipment. Utility Model Content

[0004] This utility model proposes a foldable cable chain hoist, which solves the problem that in the prior art, when the hoist is in the folded state, the traditional cable chain still needs to occupy a large vertical space, resulting in a large vertical space occupied by the equipment and hindering the miniaturization of the equipment.

[0005] The technical solution of this utility model is implemented as follows:

[0006] This utility model provides a foldable cable chain lifting machine, including a lifting mechanism and a lifting platform. The lifting mechanism is used to drive the lifting platform to rise and fall. A foldable cable chain is connected between the lifting mechanism and the lifting platform. The foldable cable chain is configured such that when the lifting mechanism drives the lifting platform to rise, the foldable cable chain folds in the vertical direction; when the lifting mechanism drives the lifting platform to fall, the foldable cable chain unfolds in the vertical direction.

[0007] Specifically, the foldable cable chain includes several cable chain units that are connected end to end in a rotating manner. When the foldable cable chain is fully folded, the connection between adjacent cable chain units is bent 180° into a "U" shape. The foldable cable chain is folded in opposite directions at the end of each cable chain unit.

[0008] Furthermore, a storage box for storing the foldable cable chain is fixedly installed on the lifting platform. The top of the storage box is open, and the width of the storage box is greater than the length of the cable chain unit.

[0009] Preferably, the panel of the storage box has a mesh-like perforated structure.

[0010] Preferably, the front panel of the storage box is detachably connected to the storage box via a snap fastener.

[0011] Specifically, the lifting mechanism includes a frame, a drive motor is installed on one side of the frame, a drum is installed inside the frame, several turns of steel wire rope are wound around the outside of the drum, a pulley is installed on the lifting platform, and the free end of the steel wire rope passes around the bottom of the pulley and is fixedly connected to the frame. The drive motor is used to drive the drum to wind or unwind the steel wire rope, thereby driving the lifting platform to rise or fall.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] (1) By connecting a foldable cable chain between the lifting mechanism and the lifting platform, the foldable cable chain automatically folds when the lifting machine is retracted (the lifting platform rises), which greatly reduces the vertical space requirement of the lifting machine in the retracted state and is conducive to the miniaturization design of the equipment.

[0014] (2) This utility model facilitates the storage of foldable cable chains by installing a storage box on the lifting platform;

[0015] (3) By designing the storage box as a mesh-like hollow structure, the weight of the storage box is greatly reduced; and by designing the front panel of the storage box as a detachable connection, it is convenient to repair the foldable cable chain inside the storage box.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 , 4 This utility model provides a foldable cable chain lifting machine, including a lifting mechanism and a lifting platform 1. The lifting mechanism is used to drive the lifting platform 1 to rise and fall. A foldable cable chain 2 is connected between the lifting mechanism and the lifting platform 1. The foldable cable chain 2 is configured such that: when the lifting mechanism drives the lifting platform 1 to rise, the foldable cable chain 2 folds in the vertical direction; when the lifting mechanism drives the lifting platform 1 to fall, the foldable cable chain 2 unfolds in the vertical direction.

[0024] This invention connects a foldable cable chain 2 between the lifting mechanism and the lifting platform 1. When the elevator is retracted (the lifting platform 1 rises), the foldable cable chain 2 automatically folds, which greatly reduces the vertical space requirement of the elevator in the retracted state and is conducive to the miniaturization design of the equipment.

[0025] Specifically, such as Figure 1 , 2 As shown, the foldable cable chain 2 includes several cable chain units 3 that are connected end to end in a rotating manner. When the foldable cable chain 2 is fully folded, the connection between adjacent cable chain units 3 bends 180° to form a "U" shape. The foldable cable chain 2 folds in opposite directions at the end of each cable chain unit 3. Each cable chain unit 3 is composed of several chain links that are hinged together by pins.

[0026] Furthermore, such as Figure 1 , 2 As shown, a storage box 4 for storing the foldable cable chain 2 is fixedly installed on the lifting platform 1. The top of the storage box 4 is open, and the width of the storage box 4 is greater than the length of the cable chain unit 3, which facilitates the storage of the folded cable chain.

[0027] In this embodiment, as Figure 2 As shown, the foldable cable chain 2 has the following form when folded:

[0028] The left end of the first cable chain unit 3 is fixedly connected to the lifting platform 1. The first cable chain unit is horizontally arranged at the bottom of the storage box 4. The right end of the second cable chain unit is bent 180° at the connection with the right end of the first cable chain unit, and the second cable chain unit is tilted with the left side lower than the right side. The left end of the second cable chain unit is pressed on the left end of the first cable chain unit. The left end of the third cable chain unit is bent 180° at the connection with the left end of the second cable chain unit, and the third cable chain unit is horizontal. The right end of the third cable chain unit is pressed on the second cable chain unit. Multiple cable chain units 3 are folded and stacked upwards in this manner to form a multi-layer folded cable chain structure. The connection between adjacent cable chain units 3 is a "U"-shaped transition structure. The purpose of this design is to make the cable chain more evenly stressed, and at the same time to avoid the ends of the cable chain units 3 being directly bent 180°. This can better protect the internal pipelines of the cable chain and prevent the pipelines from being easily broken or damaged due to being directly bent 180° at the ends of the cable chain units 3.

[0029] Preferably, such as Figure 3 As shown, the panel of the storage box 4 has a mesh-like hollow structure, which can greatly reduce the weight of the storage box 4, thereby reducing the load on the lifting mechanism.

[0030] Preferably, such as Figure 3 As shown, the front panel 5 of the storage box 4 is detachably connected to the storage box 4 via a buckle 6, which facilitates quick removal of the front panel of the storage box 4 when the foldable cable chain 2 needs to be repaired later. In this embodiment, the buckle 6 is an elastic metal buckle 6, which can be directly fastened to the mesh structure on both sides of the storage box 4.

[0031] Specifically, such as Figure 1 , 4 As shown, the lifting mechanism includes a frame 7, a drive motor 8 (with a reducer) is installed on one side of the frame 7, a drum (not shown in the figure) is installed inside the frame 7, and several turns of steel wire rope 9 are wound around the outside of the drum. A pulley 10 is installed on the lifting platform 1, and the free end of the steel wire rope 9 passes around the bottom of the pulley 10 and is fixedly connected to the frame 7. The drive motor 8 is used to drive the drum to wind or unwind the steel wire rope 9, thereby driving the lifting platform 1 to rise or fall.

[0032] In this embodiment, as Figure 4 As shown, the frame 7 has two sets, which are arranged in parallel and spaced apart. A set of steel wire ropes 9 are wound around both ends of the drum. The lifting platform 1 is a horizontal frame structure. Two pulleys 10 are installed on both sides of the frame. Each pulley 10 corresponds to a set of steel wire ropes 9. The two sets of steel wire ropes 9 at both ends of each drum correspond to the two pulleys 10 on one side of the frame. In this embodiment, a clamp is installed at the bottom of the lifting platform 1 (other equipment that needs to be lifted can also be installed). Alternatively, the lifting platform 1 can be omitted, and the equipment can be directly connected to the lifting mechanism.

[0033] In this embodiment, a scissor arm (not shown in the figure) is also connected between the frame 7 and the lifting platform 1. The scissor arm guides the lifting of the lifting platform 1, preventing the lifting platform 1 from shaking during the lifting process and improving the stability of the elevator during operation.

[0034] The working principle of the hoist in this embodiment is as follows:

[0035] When the drive motor 8 drives the drum to rotate counterclockwise, the drum winds up the wire rope 9, and the lifting platform 1 is lifted. During the lifting process, the foldable cable chain 2 undergoes multi-stage reversing bending and folding from bottom to top under its own weight and is stored in the storage box 4. When the drive motor 8 drives the drum to rotate clockwise, the drum unwinds the wire rope 9, and the lifting platform 1 descends under its own weight. The folded cable chain in the storage box 4 is gradually pulled out from top to bottom.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
