TECHNICAL FIELD

[0001] The utility model relates to a hoist device, especially to a self-adjusting battery pack hoist device. BACKGROUND

[0002] The existing battery pack hoist device mostly adopts frame structure design, which can provide stable support, but also has many inconveniences. First, the frame structure itself occupies a large space, which is particularly prominent in the limited working environment, increasing the difficulty of storage and transportation. Second, the lifting point at the top of the frame usually needs four lifting ropes to fix, which not only increases the complexity of installation, but also makes the entire hoisting process more cumbersome, significantly increasing the installation workload. In addition, due to the large distance from the edge of the frame to the center, the operator sometimes cannot reach the center position during installation, which not only increases the difficulty of operation, but also may cause the installation time to be prolonged, wasting time and effort. More seriously, the metal hook directly contacts the battery pack, which is easy to scratch the surface paint of the battery pack during hoisting, affecting the appearance and service life of the battery pack. Therefore, the existing battery pack hoist device still has room for improvement in design to solve the above problems. SUMMARY

[0017] The utility model will be further explained in detail in combination with the drawings and specific embodiment.

[0018] Figure 1 The utility model provides a kind of self-regulating type battery package hoist device, including cross cantilever, in the embodiment, cross cantilever includes first cantilever 1 and second cantilever 2, first cantilever 1 and second cantilever 2 are all strip-shaped rod body and are connected along horizontal direction and present cross by the hanger shaft assembly, specifically, on the first cantilever and second cantilever orientation setting, first cantilever and second cantilever present cross, the position of intersection point is connected with a independent lifting rope 4 upwards by the hanger shaft assembly of center intersection, and then the each endpoint of first cantilever 1 and second cantilever 2 is connected with lifting hook 3 downwards, each lifting hook is installed with guard plate 6, and battery package is hooked by the cross distribution of lifting hook, here the role of guard plate is to play the role of pad between lifting hook and battery package, guard plate is made of pom engineering plastics, on other embodiments, guard plate can adopt rubber material, but not limited to the above-mentioned material.

[0019] In this embodiment, the hanger shaft assembly includes a shaft 7 which is arranged at the intersection of the first and second cantilever arms. The shaft is cylindrical, and the upper end of the shaft is connected to the hanger rope 4 through a first hanger ring 8, so that the independent lifting force is applied at the center of the intersecting cantilever arms. It should be understood that the shaft is arranged at the center of the first and second cantilever arms in sequence, thereby limiting the first and second cantilever arms. In order to prevent the shaft from falling off the first and second cantilever arms, the end of the shaft which is arranged out of the first or second cantilever arm can be provided with a limiting lug plate, and the diameter of the limiting lug plate is larger than the diameter of the shaft. Of course, it is not limited to this fixing method, and the end cap shown in Figure 1 is connected to the shaft, thereby limiting the first and second cantilever arms from above or below;

[0020] The first and second cantilever arms are connected in an up-down staggered manner. In this embodiment, the first and second cantilever arms are cross-connected through the matching connection of the grooves arranged at the middle portions of the first and second cantilever arms. In other embodiments, the first and second cantilever arms are abutted at the upper and lower contact surfaces, or the first and second cantilever arms are welded at the upper and lower contact surfaces.

[0021] In this embodiment, the first and second cantilever arms can be simultaneously rotatably connected to the shaft due to the matching connection of the grooves. Of course, when the shaft has sufficient axial distance, the first and second cantilever arms can be stored by the matching connection mode of disengaging the grooves, thereby saving space. The rotatable connection mode can be achieved by enlarging the hole diameter of the first and second cantilever arms, or by using bearings to assist.

[0022] In other embodiments, if the first and second cantilever arms are abutted at the upper and lower contact surfaces, the first and second cantilever arms can be simultaneously rotatably connected to the shaft, or one of them is rotatably connected to the shaft, and the other one is fixed relative to the shaft. In this way, the function of storing the first and second cantilever arms can also be achieved. In another embodiment, if the first and second cantilever arms are welded to each other, the function of storing the first and second cantilever arms can only be achieved by disassembling and welding.

[0023] In all the above embodiments, the end of the first and second cantilever arms is connected to a second hanger ring 10, the upper end of the hook is connected to a third hanger ring 11, and the second hanger ring 10 is connected to the third hanger ring 11 by disengaging the buckle. Of course, the second hanger ring 10 and the third hanger ring 11 can also be connected by using hanger ropes of the same length. The hook 3 includes Figure 2 and Figure 3 the vertical plate body 32 and the bent hook 31 which is integrally bent at the vertical plate body. The guard plate is installed in the bent area formed by the vertical plate body and the bent hook. The width of the vertical plate body gradually increases from top to bottom. The guard plate is a long strip-shaped plate body, and is arranged along the length of the plate body. The guard plate is connected to the plate body by bolts.

[0025] Space saving, easy to store, the device adopts a cross cantilever design, the first cantilever and the second cantilever are connected through a groove or an upper and lower contact surface, and can rotate around the shaft body. When not in use, the cantilever can be stored by disengaging the groove or rotating, significantly reducing the occupied space and facilitating storage and transportation. Simplify the hoisting structure, reduce the installation workload, connect a single lifting rope through the lifting shaft assembly at the center intersection, simplify the hoisting structure. Only one lifting rope is needed to realize hoisting, reducing the installation workload and improving the operation efficiency. Easy to operate, strong adaptability, through the cross distribution of the lifting hook design, the lifting hook position can be adjusted flexibly according to the size of the battery pack, the operator does not need to touch the center position, the hoisting process is more convenient. In addition, the rotatable design of the cantilever further enhances the adaptability of the device. Protect the surface of the battery pack and avoid damage, the metal lifting hook directly contacts the battery pack, which is easy to scratch the surface paint. The device is installed with a protective plate on the lifting hook, which is made of POM engineering plastic or rubber material, which can act as a cushion between the lifting hook and the battery pack, effectively preventing direct contact and damage of the metal lifting hook to the surface of the battery pack. Stable structure, high safety, the device ensures the stable connection of the first cantilever and the second cantilever during hoisting through the design of the lifting shaft assembly and the limiting lug (or end cover), preventing falling. At the same time, the vertical plate body of the lifting hook gradually widens from top to bottom, enhancing the carrying capacity and stability of the lifting hook. Multifunctional, suitable for different scenarios, through the rotatable design of the cantilever, the material selection of the protective plate (such as POM engineering plastic or rubber) and the flexible adjustment of the lifting hook, it can adapt to battery packs of different sizes, shapes and weights, meeting various hoisting needs.
