Description

Technical Field

[0001] This utility model belongs to the field of hoisting technology, and in particular relates to a hoisting device and a battery pack hoisting equipment. Background Technology

[0002] In hoisting operations involving heavy goods such as battery packs and industrial equipment, manual handling is difficult, and slings or hooks are typically required. Because battery packs inherently possess elongated through-hole structures for installation, and these vertically positioned, high-strength structures can be directly used as hoisting points.

[0003] If hoisting is done using ropes, the ropes need to be threaded through the various long through-hole structures before being secured to the lifting device. However, because the ropes are relatively soft, they are often made quite thick to ensure strength. When passing through the long through-holes, they can only be squeezed slowly, which is inefficient. If a rope with multiple holes is used, the rope length needs to be repeatedly adjusted to ensure that the rope length reserved at each lifting point is consistent. If a rope with one hole is used, each rope needs to be secured individually, which greatly affects the production cycle. If hooks are used for hoisting, the commonly used round hooks are only suitable for thin-walled structures and cannot be adapted to the long through-holes of thick structures. Ordinary long straight hooks are not securely fixed, do not have a locking function, and pose a risk of falling off. In addition, the hooks themselves are not flexible and have poor compatibility, requiring repeated changes to the hook model. Custom development is necessary for special structures.

[0005] To achieve the above objectives, the first aspect of this utility model provides a hoisting device, wherein the hoisting device includes a hoisting sling and a self-locking assembly; the upper end of the hoisting sling is used for hoisting; the self-locking assembly includes a fixed support member and a movable locking member, the upper end of the fixed support member is connected to the lower end of the hoisting sling, the fixed support member is also provided with a limiting space and an upwardly facing support surface, the movable locking member is vertically inserted through the limiting space and is provided with a sliding surface that conforms to the support surface for movement, the lower end of the movable locking member extends out of the limiting space and a locking plate extends out on the side away from the fixed support member, and the support surface is inclined downward in the direction of movement away from the movable locking member.

[0006] In one embodiment of the present invention, the fixed support member includes a limiting ring portion and a fixed column portion. The limiting ring portion is provided with a limiting space. The upper parts of the fixed column portion and the movable locking member are both provided in the limiting space, and the lower parts both extend out of the limiting space. The fixed column portion is fixedly connected to the limiting ring portion. The side of the fixed column portion facing the movable locking member has a supporting surface below the limiting ring portion.

[0007] In one embodiment of the present invention, the fixed column includes a hoisting section and a support section arranged sequentially from top to bottom. The upper end of the hoisting section is connected to the lower end of the hoisting cable. The hoisting section passes through the limiting space and is fixedly connected to the limiting ring. The support section is located below the limiting ring and has a support surface on the inner side of the hoisting section.

[0008] In one embodiment of this utility model, the side of the support section away from the movable locking member is provided with a downward-facing stepped surface.

[0009] In one embodiment of this utility model, the upper end face of the support section extends out from the inside of the hoisting section to form a support surface.

[0010] In one embodiment of the present invention, the movable locking member includes a mating section and a locking section arranged sequentially from top to bottom. The mating section passes through the limiting space, and the lower end face of the mating section extends out of the inner side of the locking section to form a sliding surface. The lower end of the locking section has a locking plate extending out on the side away from the fixed support member.

[0011] In one embodiment of this utility model, the inclination angle of the supporting surface or sliding surface is set to 10°~45°.

[0012] In one embodiment of this utility model, the fixed support member is further provided with a first clearance mating surface and a second clearance mating surface. The first clearance mating surface and the second clearance mating surface are disposed on the same side as the support surface and are respectively disposed on the upper and lower sides of the support surface.

[0019] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0020] The hoisting device and battery pack lifting equipment of this utility model are described below with reference to the accompanying drawings.

[0021] like Figures 1 to 5 As shown, this utility model provides a hoisting device, which includes a hoisting cable 100 and a self-locking assembly. The upper end of the hoisting cable 100 is used for hoisting. The self-locking assembly includes a fixed support member 200 and a movable locking member 300. The upper end of the fixed support member 200 is connected to the lower end of the hoisting cable 100. The fixed support member 200 is also provided with a limiting space 211 and an upwardly facing support surface 223. The movable locking member 300 is vertically inserted through the limiting space 211 and is provided with a sliding surface 301 that conforms to the support surface 223 for movement. The lower end of the movable locking member 300 extends out of the limiting space 211 and a locking plate 305 extends out on the side away from the fixed support member 200. The support surface 223 is inclined downward in the direction of moving away from the movable locking member 300. Specifically, the self-locking assembly is used to pass through the hoisting hole 400 when the movable locking member 300 is retracted close to the fixed support member 200, and the locking plate 305 is used to hook the lower periphery of the hoisting hole 400 when the movable locking member 300 is spaced away from the fixed support member 200.

[0022] When using the above-mentioned lifting device, the movable locking member 300 can first be moved on the support surface 223 towards the fixed support member 200, so that the movable locking member 300 switches to the unlocked state of retracting towards the fixed support member 200. At this time, the radial dimension of the self-locking component at the locking plate 305 becomes smaller, and it can pass through the lifting hole 400 of the component to be lifted (battery pack). After the self-locking component passes through the lifting hole 400, the movable locking member 300 is then moved away from the fixed support member 200 on the support surface 223 until the movable locking member 300 moves to abut against the inner wall of the limiting space 211. Next, the locking plate 305 moves to hook the lower periphery of the lifting hole 400. Since the supporting surface 223 is inclined downwards along the direction of movement of the movable locking member 300, during the lifting process, the movable locking member 300 is clamped between the inner wall of the limiting space 211 and the supporting surface 223, ensuring a stable locking state and achieving lifting and locking of the part to be lifted. Compared with slings, the lifting device provided by this utility model significantly improves installation efficiency; compared with hooks, it significantly improves compatibility, and the height and wall thickness of the lifting hole are not limited. It should be noted that the lifting device provided by this utility model is particularly suitable for the long through-hole structure of the battery pack itself, but this utility model is not limited thereto. If other parts to be lifted use the lifting device provided by this utility model, they should also fall within the protection scope of this utility model.

[0023] Specifically, after the movable locking member 300 is inserted into the limiting space 211 of the fixed support member 200, there is still space for the movable locking member 300 to move radially. Even if the movable locking member 300 moves to the position where the maximum gap is formed between it and the fixed support member 200, the sliding surface 301 of the movable locking member 300 is always in contact with the support surface of the fixed support member 200 to ensure the stability of the movable locking member 300 installed on the fixed support member 200.

[0024] In one embodiment of this utility model, the fixed support member 200 includes a limiting ring portion 210 and a fixed post portion 220. The limiting ring portion 210 is provided with a limiting space 211. The upper parts of both the fixed post portion 220 and the movable locking member 300 are disposed within the limiting space 211, and the lower parts of both extend out of the limiting space 211. The fixed post portion 220 is fixedly connected to the limiting ring portion 210. A support surface 223 is provided below the limiting ring portion 210 on the side of the fixed post portion 220 facing the movable locking member 300. That is, the fixed support member 200 can be manufactured separately for the limiting ring portion 210 and then fixedly connected to the limiting ring portion 210, thereby facilitating manufacturing and saving production costs. In addition, placing the support surface 223 below the limiting ring portion 210 facilitates observation. Specifically, the upper end of the fixed column portion 220 can be connected to the lower end of the lifting cable 100. Both the limiting ring portion 210 and the fixed column portion 220 can be made of metal, and the connection method between the two components includes, but is not limited to, welding. Of course, this utility model is not limited to this. It is also possible for the upper end of the limiting ring portion 210 to be connected to the lower end of the lifting cable 100, and it is also possible for the limiting ring portion 210 and the fixed column portion 220 of the fixed support member 200 to be integrally formed, manufactured by integral forming process or machining.

[0025] In one embodiment of this utility model, the fixed column portion 220 includes a lifting section 221 and a support section 222 arranged sequentially from top to bottom. The upper end of the lifting section 221 is connected to the lower end of the lifting cable 100. The lifting section 221 passes through the limiting space 211 and is fixedly connected to the limiting ring portion 210. The support section 222 is located below the limiting ring portion 210, and the support section 222 has a support surface 223 on the inner side of the lifting section 221. Specifically, the side of the support section 222 away from the movable locking member 300 has a downwardly facing stepped surface 224. By adding the stepped surface 224, the radial dimension of the support section 222 can be reduced, thereby reducing the space occupied by the support section 222 in the lifting hole 400, leaving more space for the movable locking member 300 and its movement. In addition, it can also ensure the strength of the part of the fixed column portion 220 above the stepped surface 224.

[0026] In one embodiment of this utility model, the upper end face of the support section 222 extends outward from the inner side of the hoisting section 221 to form a support surface 223. That is, the support surface 223 is directly formed by extending outward from the upper end face of the support section 222 and forms a step shape with the inner side of the hoisting section 221. Thus, the inner side of the hoisting section 221 can stop the movable locking member 300.

[0027] See Figure 4 , Figure 5 and Figure 7In one embodiment of this utility model, the movable locking member 300 includes a mating section 310 and a locking section 320 arranged sequentially from top to bottom. The mating section 310 passes through the limiting space 211, and the lower end face of the mating section 310 extends out of the inner side of the locking section 320 to form a sliding surface 301. The lower end of the locking section 320 has a locking plate 305 extending out from the side opposite to the fixed support member 200. That is, the sliding surface 301 is directly formed by the lower end face of the mating section 310 and forms a step shape with the inner side of the locking section 320. Thus, the inner side of the locking section 320 can stop the support section 222 of the fixed column 220.

[0028] In one embodiment of this utility model, the inclination angle of the support surface 223 or the sliding surface 301 can be set to 10°~45°, so that the support surface 223 can support the movable locking member 300 while ensuring that the movable locking member 300 can slide automatically.

[0029] like Figures 5 to 7 As shown, in one embodiment of this utility model, the fixed support member 200 is further provided with a first clearance mating surface 225 and a second clearance mating surface 226. The first clearance mating surface 225 and the second clearance mating surface 226 are disposed on the same side as the support surface 223 and are respectively disposed on the upper and lower sides of the support surface 223. The movable locking member 300 is further provided with a third clearance mating surface 302 and a fourth clearance mating surface 303. The third clearance mating surface 302 and the fourth clearance mating surface 303 are disposed on the same side as the sliding surface 301 and are respectively disposed on the upper and lower sides of the sliding surface 301. All clearance mating surfaces are set as vertical straight surfaces. This allows the first clearance mating surface 225 to fit with the third clearance mating surface 302, and / or the second clearance mating surface 226 to fit with the fourth clearance mating surface 303, when the movable locking member 300 retracts and approaches the fixed support member 200. This allows the movable locking member 300 to be retracted and moved into place by the stops of the corresponding clearance mating surfaces. In addition, using vertical flat surfaces for fitting also facilitates processing.

[0030] See Figure 1In one embodiment of this utility model, the lower end of the hoisting cable 100 is forked to form a supporting sling section 110 and a locking sling section 120. The lower end of the supporting sling section 110 is connected to the upper end of the fixed support member 200, and the lower end of the locking sling section 120 is connected to the upper end of the movable locking member 300. The length of the locking sling section 120 is set to be greater than the length of the supporting sling section 110. When lifting is performed at the upper end of the lifting cable 100, the supporting cable section 110, being shorter, will apply force before the locking cable section 120. This allows the lifting to be performed on the fixed support member 200 through the supporting cable section 110. The addition of the locking cable section 120 serves two purposes: firstly, it connects the movable locking member 300 to the lifting cable 100; secondly, when it is necessary to move the movable locking member 300 closer to the fixed support member 200, the locking cable section 120 can be pulled, thus facilitating the application of force and movement.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, in one embodiment of this utility model, the upper end of the movable locking member 300 is provided with a separating boss 304 between the supporting sling section 110 and the locking sling section 120. By adding the separating boss 304, the supporting sling section 110 and the locking sling section 120 can be separated to avoid entanglement.

[0032] Please see again Figure 1 In one embodiment of this utility model, the upper end of the lifting cable 100 is provided with a hook hole 101 for lifting, which facilitates lifting and retrieval operations.

[0033] In one embodiment of this utility model, the lifting cable 100 includes a metal chain. The metal chain is a hinged lifting cable, which facilitates directional adjustment. Of course, this utility model is not limited to this; the lifting cable 100 may also include a metal wire rope or a synthetic fiber rope, etc.

[0034] Specifically, the hoisting process of the hoisting device provided by this utility model can be as follows: 1. Before hoisting and assembly, the movable locking member 300 is lifted by locking the sling section 120, so that it is brought close to the fixed support member 200. At this time, the radial dimension of the self-locking assembly at the locking plate 305 reaches the minimum dimension L1.

[0035] 2. Pass the lower end of the self-locking component through the hoisting hole 400, where the minimum dimension L1 is smaller than the diameter D of the hoisting hole 400.

[0036] 3. Loosen the locking sling section 120. Under the action of gravity, the movable locking part 300 naturally slides down to the bottom along the inclined downward support surface 223. At this time, the radial dimension of the self-locking component at the locking plate 305 reaches the maximum dimension L2. The locking plate 305 moves to hook the lower periphery of the hoisting hole 400, realizing the automatic hoisting and locking of the hoisting part.

[0037] 4. Lifting cable 100 is used to lift the fixed support 200. During the lifting process, the lifting cable 100 provides an upward force to the fixed support 200, and the self-locking assembly will maintain the maximum size L2 unchanged.

[0038] 5. After placing the product in the target position, lift the movable locking member 300 by locking the sling section 120, so that it is close to the fixed support member 200. At this time, the radial dimension of the self-locking assembly at the locking plate 305 reaches the minimum dimension L1.

[0039] 6. Remove the self-locking component from within 400mm of the hoisting hole.

[0040] Furthermore, the hoisting device provided by this utility model has the following effects: 1. By using a staggered assembly method, the hoisting structure can be automatically locked by gravity with just a gentle pull and release. The process is convenient and quick, and no other tools are required.

[0041] 2. Small in size, light in weight, and does not take up extra space, making it easy to carry and store.

[0042] 3. It has strong compatibility, with no restrictions on the height and wall thickness of the lifting holes, and has obvious advantages in long hole structures and thick-walled hole structures.

[0043] Furthermore, this utility model also provides a battery pack lifting device, which includes a lifting device and a hoisting device according to the above description. The lifting device is used to lift the hoisting cable 100.
