Description

Technical Field

[0001] This utility model relates to the field of battery pack maintenance technology, specifically to a fork tooth quick alignment and locking device. Background Technology

[0002] A battery pack is generally composed of multiple battery cells and is the main power source for electrical equipment. Battery packs typically weigh between 500-1500 kg. During battery pack maintenance, external clamping tools, such as forklifts or cranes, are required to lift the battery pack to a certain height before performing maintenance operations.

[0003] CN120319911A discloses a battery pack maintenance device, including a support assembly and a fork assembly. The fork of the fork assembly is disposed in the operating space inside the main support. At least one bridging member and a tensioning member are provided on the fork, and the battery pack is detachably mounted on the bridging member. When the battery pack is placed on the fork, the fork is subjected to the weight of the battery pack, placing high demands on the load-bearing capacity of the fork. The fork, also known as the fork tooth, is prone to fatigue; even after long-term use, it can lead to fork tilting or deformation, affecting the safety of battery pack maintenance operations. Furthermore, fixing the fork to the lifting ring with a rope results in poor operability. Utility Model Content

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. 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.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings:

[0036] Example 1 provides a quick-alignment locking device for forks, such as Figures 1-5 As shown, the device includes a gripper 1, a second mounting rod 6, and an adjustment mechanism 13. The adjustment mechanism 13 includes a first mounting rod 2, a first screw 3, and a second screw 4. The first mounting rod 2 has first nuts 21 on its upper and lower sides, and the first screw 3 and the second screw 4 are respectively mounted on the two first nuts 21. A front fork assembly 73 is provided inside the bracket 7. A crossbeam 71 is provided on the upper side of the bracket 7, and the gripper 1 is slidably mounted on the crossbeam 71. The upper side of the first screw 3 is mounted on the gripper 1, and the lower side of the second screw 4 is detachably mounted on the horizontally arranged second mounting rod 6. The fork teeth 75 of the front fork assembly 73 are detachably mounted on the second mounting rod 6.

[0037] The relative position of the second mounting rod 6 and the fork 75 is adjusted by sliding the claw 1, so that the fork 75 can be quickly aligned. The second mounting rod 6 and the fork 75 can be quickly locked by the detachable structure. The force on the fork 75 is transmitted to the crossbeam 71 of the bracket 7 through the second mounting rod 6, the adjustment mechanism 13 and the claw 1, so as to achieve force balance of the fork 75 and prevent fatigue of the fork 75. The height of the second mounting rod 6 can be adjusted by rotating the first mounting rod 2 to accommodate fork 75 of different heights.

[0038] The inner side of the first mounting rod 2 is provided with a receiving cavity 22, and the first nut 21 is installed in the receiving cavity 22.

[0039] In this design, the first screw 3 and the second screw 4 have opposite helical directions. For example, when the first mounting rod 2 rotates clockwise, the first mounting rod 2 moves upward along the first screw 3, and the corresponding second screw 4 moves upward along the first mounting rod 2. However, this is not a limitation; the clockwise rotation can also be used to decrease the height of the helix.

[0040] Example 2, as Figure 2 As shown, a handle 25 is provided on the first mounting rod 2 to facilitate rotation of the first mounting rod 2.

[0041] Example 3, as Figure 3 As shown, the inner side of the first screw 3 is provided with an anti-detachment protrusion 31, which serves as a limit to prevent the first screw 3 from detaching from the first mounting rod 2. Correspondingly, the inner side of the second screw 4 is also provided with an anti-detachment protrusion 31.

[0042] Example 4, Figure 4 and Figure 5 The mounting structure of the second screw 4 and the fork tooth 75 is shown. The lower side of the second screw 4 is mounted on the second mounting rod 6 via a third nut 53. More specifically, a second nut 51 is also provided on the second screw 4 to facilitate fastening of the second screw 4 and the second mounting rod 6.

[0043] The front side of the fork tooth 75 is mounted on the second mounting rod 6 via the fourth screw 55 and the fourth nut 57.

[0044] More specifically, the second mounting rod 6 is provided with a first mounting groove 61 and a second mounting groove 63, and the second screw 4 is installed on the second mounting groove 63 to facilitate adjustment of the horizontal position of the second mounting rod 6; the fork tooth 75 is installed on the first mounting groove 61, which can accommodate two fork teeth 75 with different spacing, improve adaptability, and can accommodate the horizontal length difference of battery packs of different sizes.

[0045] The third nut 53 and the fourth nut 57 can be hand-tightened, and a handle 56 is provided on one side of the fourth screw 55 for easy installation.

[0046] Example 5 provides an alternative solution, wherein the adjustment mechanism 13 includes a first mounting rod 2 and a first screw 3; the adjustment mechanism 13 includes a first mounting rod 2 and a first screw 3; a first nut 21 is provided on one side of the first mounting rod 2, and the first screw 3 is mounted on the first nut 21; one end of the adjustment mechanism 13 is mounted on the gripper 1, and the other end is rotatably mounted on the second mounting rod 6; a front fork assembly 73 is provided inside the bracket 7; a crossbeam 71 is provided on the upper side of the bracket 7; the gripper 1 is mounted on the crossbeam 71; the fork teeth 75 of the front fork assembly 73 are detachably mounted on the second mounting rod 6.

[0047] After the battery pack is flipped by the front fork assembly 73, the vertical travel is adjusted by rotating the first mounting rod 2 via the thread to accommodate the height difference after the battery packs of different sizes are flipped.

[0048] The gripper 1 is fixed to the crossbeam 71 by ball screws 11 on the side wall, and can be quickly positioned by ball screws 11 on the gripper.

[0049] Two sets of adjustment mechanisms 13 are respectively installed on the crossbeams 71 on the left and right sides of the bracket 7; the two sides of the second mounting rod 6 are respectively installed on the lower side of one set of adjustment mechanisms 13.

[0050] This invention enables rapid alignment and locking of the fork teeth, preventing safety hazards caused by the fork teeth falling due to force or pressure relief. Anti-detachment bosses 31 are designed in the first screw 3 and the second screw 4 to prevent accidental drop due to excessive rotation. The height of the second mounting rod 6 can be adjusted by rotating the handle 25 and the first mounting rod 2, and the horizontal position of the second mounting rod 6 can be adjusted by sliding the claw 1, achieving rapid alignment of the second mounting rod 6. Multiple hand-tightened nuts enable rapid locking, facilitating operation and improving the efficiency of fork tooth alignment and locking.

[0051] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
