Description

[0001] The utility model relates to battery transportation technical field especially relates to a battery hoist device. BACKGROUND

[0002] In the production, storage and transportation links of the battery industry, the hoisting operation of the battery is a very common and key operation process. Traditionally, the battery hoisting method generally adopts the form of passing through the bottom of the battery box. In actual operation, before each hoisting, the staff needs to manually pass the strap through the bottom of the box carefully and perform multiple binding and fixing operations to ensure the stability of the battery during hoisting. However, this process not only consumes time and effort, but also requires a high level of proficiency from the operator. After completing the hoisting task, a lot of time has to be spent to untie the straps one by one, and the entire operation process is complicated and time-consuming, which seriously affects the work efficiency.

[0003] More seriously, the strap fixing method has a congenital stability defect. Since the battery is affected by various external forces during hoisting, such as inertial force during lifting and shaking during movement, once the battery pack tilts, the friction between the strap and the box will quickly decrease, causing the strap to loosen. In this case, the battery is prone to tipping and falling, which not only may cause damage to the expensive battery, resulting in significant economic losses, but also poses a serious safety threat to the surrounding operators and other equipment, and may even cause a major safety accident.

[0039] In the embodiment, the first hoisting rings 110 are arranged on the hoisting support 100 to facilitate hoisting by external hoisting equipment.

[0040] In one of the embodiments, the lifting support 100 comprises at least two horizontal rods 130 and at least one vertical rod 140, each of the horizontal rods 130 is arranged in parallel with each other, each of the horizontal rods 130 is connected with the vertical rod 140 respectively, and the horizontal rod 130 and the vertical rod 140 are arranged at an angle. Specifically, in the embodiment, the box body 400 of the battery pack is in a cuboid structure, the lifting support 100 comprises three horizontal rods 130 and three vertical rods 140, the three horizontal rods 130 and the three vertical rods 140 are connected with each other to form a square frame structure. Among them, the first lifting ring 110 and the second lifting ring 120 are arranged on the two outermost horizontal rods 130 respectively, and the distance between the two outermost horizontal rods 130 is equal to the width of the battery pack, the width of the battery pack is the distance between the two faces of the box body 400 on which the lifting grooves 410 are arranged respectively, so that the lifting connector 210 remains in a vertical state during the lifting operation, reducing the inclination of the lifting connector 210 towards the side of the box body 400 to cause extrusion deformation or scratching of the box body 400.

[0041] Of course, in other embodiments, other number of horizontal rods 130 and vertical rods 140 can also be used in the structural design, such as two horizontal rods 130 and three vertical rods 140, three horizontal rods 130 and two vertical rods 140, or four horizontal rods 130 and four vertical rods 140, etc., as long as a stable lifting support 100 can be formed through the connection of the horizontal rod 130 and the vertical rod 140 to ensure the stability of the lifting and avoid damage to the box body 400, such design is within the protection scope of the present application.

[0042] In one of the embodiments, the lifting support 100 further comprises a fixing seat 150, the fixing seat 150 is arranged at the connection between the horizontal rod 130 and the vertical rod 140, the fixing seat 150 comprises two first limiting portions 151 and two second limiting portions 152, the two first limiting portions 151 are arranged in parallel along the width direction of the horizontal rod 130 and abut against the two sides of the horizontal rod 130 along the width direction thereof to limit the displacement of the horizontal rod 130 along the width direction thereof. The two second limiting portions 152 are arranged in parallel along the width direction of the vertical rod 140 and abut against the two sides of the vertical rod 140 along the width direction thereof to limit the displacement of the vertical rod 140 along the width direction thereof. Thus, the fixing seat 150 is used to further limit and fix the horizontal rod 130 and the vertical rod 140, to ensure the fixing strength of the overall lifting support 100 and the safety of the lifting.

[0043] In actual operation, four first lifting rings 110 and four second lifting rings 120 are arranged respectively, and the gravity centers of the lifting support 100 in the rectangular frame structure are arranged uniformly, the external lifting equipment comprises four lifting chains 300, which are connected with the first lifting ring 110 respectively to ensure horizontal lifting.

[0044] In one of the embodiments, the mounting base 222 is provided with a rotating shaft 2224, the adapter member 221 is provided with a plug hole 2211 having a first abutting wall 2212, the adapter member 221 is provided with an opening 2214 communicating with the plug hole 2211, the rotating shaft 2224 is plugged into the plug hole 2211 through the opening 2214, when the adapter member 221 is in the first position, the first abutting wall 2212 abuts against the lower surface of the rotating shaft 2224, at this time, the first abutting wall 2212 provides a support force for the shaft, so that when the lifting connector 210 pulls the adapter member 221 upward, the adapter member 221 pulls the rotating shaft 2224 upward, i.e. pulls the mounting base 222 upward to pull the box body 400 of the battery pack upward, thereby realizing the lifting operation of the battery pack. At the same time, the opening 2214 is located on the side of the rotating shaft 2224 away from the box body 400 in the horizontal direction, i.e. the adapter member 221 is limited by the rotating shaft 2224 and the box body 400 and cannot be pulled out, thereby effectively ensuring the safety during lifting.

[0045] In one of the embodiments, the mounting base 222 is further provided with a support portion 2227, when the adapter member 221 is in the first position, the support portion 2227 is located on the side of the adapter member 221 close to the box body 400, and the support portion 2227 abuts against the connecting frame, thereby supporting the connecting frame and preventing the connecting frame from directly abutting against the side surface of the box body 400, thereby avoiding the damage of the box body 400 caused by the collision or friction between the connecting frame and the box body 400.

[0046] In one of the embodiments, the plug hole 2211 is further provided with a second abutting wall 2213 opposite to the first abutting wall 2212, the rotating shaft 2224 is provided with two first side surfaces 2225 opposite to each other and two second side surfaces 2226 opposite to each other, when the adapter member 221 is in the first position, the first abutting wall 2212 and the second abutting wall 2213 abut against the two first side surfaces 2225, respectively. Among them, the maximum distance between the two first side surfaces 2225 is L1, the maximum distance between the two second side surfaces 2226 is L2, the maximum distance between the first abutting wall 2212 and the second abutting wall 2213 is L3, L3 = L1 > L2. So that when the adapter member 221 is in the first position, the adapter member 221 is connected stably with the rotating shaft 2224, and when the adapter member 221 is in the second position, the adapter member 221 can be separated from the rotating shaft 2224.

[0047] Furthermore, the first abutment wall 2212 and the second abutment wall 2213 are configured as arcs, and the first sidewall is configured as an arc corresponding to the first abutment wall 2212 and the second abutment wall 2213. That is, the first abutment wall 2212 and the second abutment wall 2213 respectively contact the two first sidewall surfaces, having sufficient contact area, so that the adapter member 221 provides more stable support for the rotating shaft 2224. Moreover, when the adapter member 221 rotates relative to the rotating shaft 2224, the friction between the sidewall of the insertion hole 2211 and the surface of the rotating shaft 2224 is reduced, thus reducing wear on the sidewall of the insertion hole 2211 and the surface of the rotating shaft 2224. Specifically, in actual operation, the cross-section of the rotating shaft 2224 is racetrack-shaped or elliptical.

[0048] In one embodiment, the adapter member 221 includes two spaced-apart adapter arms 2215, with one side of the two adapter arms fixedly connected by a connecting arm 2216. The adapter arms 2215 and the connecting arm 2216 surround each other to form a clearance groove 2217 for the mounting base 222 to pass through, so as to prevent motion interference between the adapter member 221 and the mounting base 222 during rotation. Moreover, the connecting arm 2216 and the mounting base 222 are spaced apart to form a lifting gap 230 so that the lifting connector 210 passes through the lifting gap 230 and connects with the connecting arm 2216.

[0049] In one embodiment, the mounting base 222 is further provided with a plug-in block 2221 for engaging with the lifting slot 410 on the housing 400. The top of the plug-in block 2221 is provided with a first lifting surface 2222, and the lifting slot 410 is provided with a second lifting surface 411 that abuts against the first lifting surface 2222. Thus, during the lifting operation, the housing 400 is supported by the plug-in block 2221. That is, during the lifting process, the force is mainly borne by the first lifting surface 2222 of the plug-in block 2221, which helps to improve the overall load-bearing capacity and safety of the lifting assembly 200.

[0050] In one embodiment, the mounting base 222 has a first mounting hole 2223 through which the locking bolt 500 passes, and the inner wall of the lifting groove 410 has a second mounting hole 412. The locking bolt 500 passes through the first mounting hole 2223 and is threadedly connected to the second mounting hole 412, thereby fixing the mounting base 222 to the housing 400. The locking bolt 500 includes a bolt head 510, which is located on the side of the mounting base 222 facing away from the lifting groove 410. The size of the bolt head 510 is larger than the size of the first mounting hole 2223, thereby preventing the mounting base 222 from coming out of the lifting groove 410 and ensuring that the mounting base 222 is securely fixed to the housing 400. Of course, in actual operation, the locking bolt 500 can also be threadedly connected to the first mounting hole 2223 and the second mounting hole 412 respectively to ensure that the locking bolt 500 securely fixes the mounting base 222 and the housing 400.

[0051] Further, by adopting the face contact between the plug-in block 2221 and the hoisting groove 410, the shear force of the battery pack on the locking bolt 500 in the gravity direction during hoisting can be effectively reduced, the stress of the locking bolt 500 is reduced, the locking bolt 500 mainly plays a connecting and fixing role, the connection stability of the locking bolt 500 can be effectively ensured, and the service life of the locking bolt 500 is improved.

[0052] In one of the embodiments, the plug-in block 2221 is provided with a mounting groove 2228, the first mounting hole 2223 is arranged on the bottom wall of the mounting groove 2228, the bolt head 510 is arranged in the mounting groove 2228, and the end of the bolt head 510 away from the bottom wall does not exceed the slot of the mounting groove 2228. In order to avoid the collision between the bolt head 510 protruding from the slot of the mounting groove 2228 and external objects during hoisting and transportation, the bolt head 510 is damaged, so as to affect the connection strength of the locking bolt 500 to the mounting seat 222 and the box body 400, and the mounting seat 222 is separated.

[0053] In one of the embodiments, the hoisting connecting piece 210 and the second lifting ring are detachably connected through the bow-shaped shackle, so as to realize the dismounting operation of the hoisting connecting piece 210 and the second lifting ring, reduce the difficulty of the dismounting operation, improve the dismounting efficiency, and thus improve the overall operation efficiency.

[0054] In one of the embodiments, the hoisting connecting piece 210 is arranged in a flat hoisting belt. The flat hoisting belt can effectively avoid the damage to the surface of the box body 400. Meanwhile, in the actual hoisting operation process, the box body 400 needs to be hoisted and placed into the bracket of the transport vehicle. The flat hoisting belt can save space and avoid the interference between the hoisting belt and the bracket, so as to facilitate the placement of the box body 400 into the bracket.

[0055] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not the limitation of the embodiments of the utility model. For ordinary skilled in the art, various obvious changes, re-adjustment and replacement can be made without departing from the protection scope of the utility model. Here, it is unnecessary and impossible to enumerate all the embodiments.
