[0002] Battery electrolyte storage tanks are widely used with the wide application of new energy. Battery electrolyte storage tanks need to use end caps when they are used. End caps refer to components used to seal the ends of containers to isolate the internal and external media. End caps are also called end caps. They are used to seal the opening of the tank to ensure the tightness and safety of the closed container.

[0003] Because there is a hole in the center of the head, two workers usually need to use suction cups to flip the head before handling it during the processing. During the flipping of the suction cup, the head is curved and it is easy to lose the suction and cause the product to fall off. It is easy to cause personal injury. Summary of the invention

[0004] The present invention aims to solve the problem in the prior art that the end cap is prone to fall off during transportation due to the curved surface of the end cap not being firmly sucked, and the following technical solution is proposed:

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings of the specification.

[0029] Example

[0030] Figure 1-Figure 4 In the embodiment, a small hole end cap lifting device comprises: an end cap product 9 and a lifting assembly, wherein the lifting assembly reciprocates in the vertical direction to be inserted into or leave the middle small hole position of the end cap product 9, wherein the lifting assembly comprises a movable hook 5, a pushing part and a lifting block connected with an external lifting device, wherein the lifting block is composed of an upper fixing sleeve 3 and a lower fixing seat 4, wherein the movable hook 5 is movably inserted between the upper fixing sleeve 3 and the lower fixing seat 4, and wherein the pushing part pushes the movable hook 5 to extend out or retract on the surface of the lifting block;

[0031] After the lifting block is inserted into the small hole in the middle of the head product 9 under the movement of the external lifting equipment, the pushing part pushes the movable hook 5 to extend from the surface of the lifting block to restrict the head product 9, and the restricted head product 9 can be lifted by moving the lifting block.

[0032] The upper fixing sleeve 3 and the lower fixing seat 4 are fixedly connected by a plurality of fixing bolts 7 , and the grooves in the middle of the upper fixing sleeve 3 and the lower fixing seat 4 form a middle groove of the lifting block for accommodating the movable hook 5 and the pull rod 2 .

[0033] When the head product 9 needs to be lifted, the external lifting equipment moves the lifting block to insert it from the small hole in the middle of the head product 9, and uses the external equipment to provide power to the pushing part to extend the movable hook 5 from the surface of the lifting block. Multiple movable hooks 5 limit the head product 9. Then the external lifting equipment lifts the head product 9 to the required position, and uses the external equipment to reset the pushing part so that the movable hook retracts from the surface of the lifting block. The lifting block can then be detached from the small hole in the middle of the head product 9 to complete the lifting work.

[0034] The lifting component is inserted into the small hole in the middle of the head product 9, and the lifting component restricts the head product 9 to prevent the head product 9 from falling off the lifting component, thereby preventing the head product 9 from falling off during the lifting process and causing personal injury.

[0035] The lifting method of the small hole end cap lifting device comprises the following steps:

[0036] S1. Preparation for lifting;

[0037] The external lifting device moves the lifting block to insert it from the middle small hole of the head product 9, and then uses the external device to provide power for the pushing part;

[0038] S2, end product 9 limit;

[0039] The pull rod 2 moves upward to push the multiple movable hooks 5 to extend from the surface of the lifting block and stretch the return circular tension spring 6 to deform, and the multiple movable hooks 5 limit the end product 9;

[0040] S3, lifting is completed;

[0041] The external device pushes the pull rod 2 downward, and the return circular tension spring 6 is reset to retract the multiple movable hooks 5 from the surface of the lifting block, and the head product 9 without restriction automatically falls down to complete the lifting work.

[0042] Figure 1-Figure 4 In the figure, the pushing part includes a pull rod 2 which is movably inserted in the lifting block. The bottom of the pull rod 2 is arranged in an inclined step shape. The inclined surface at the bottom of the pull rod 2 matches the movable hook 5. One end of the pull rod 2 extends to the outside of the lifting block. The end of the pull rod 2 is provided with a lifting ring 1 connected to an external power device.

[0043] The lifting ring 1 is threadedly sleeved on the surface of the pull rod 2 , and the lifting ring 1 and the pull rod 2 are fixed in position by fixing screws 8 .

[0044] The pushing part further comprises a return circular tension spring 6, one end of which is sleeved on the surface of the movable hook 5, and the return circular tension spring 6 is used to transform the movable hook 5 from extending out to contracting and returning.

[0045] The movable hooks 5 are multiple in number, and the multiple movable hooks 5 are circumferentially arranged relative to the middle of the lifting block, and the return circular tension spring 6 is sleeved on the surfaces of the multiple movable hooks 5.

[0046] When it is necessary to use the lifting assembly to restrict the head product 9, the external equipment pushes the pull rod 2 upward through the lifting ring 1. Since the bottom of the pull rod 2 is arranged in an inclined step shape, and the inclined surface of the bottom of the pull rod 2 matches the movable hook 5, the upward pull rod 2 extends multiple movable hooks 5 outward in the middle groove of the lifting block, and the return circular tension spring 6 is stretched and deformed accordingly, and multiple movable hooks 5 restrict the head product 9. When the head product 9 is released, the external equipment disconnects the restriction on the pull rod 2. Under the resetting action of the return circular tension spring 6, multiple movable hooks 5 move inward at the same part to transform the movable hooks 5 from extending out to contracting and returning, until the bottom of the pull rod 2 contacts the surface of the lower fixed seat 4, and the head product 9 in a free state can fall from the lifting assembly.

[0047] The state of the movable hook 5 is changed by moving the pull rod 2 up and down, thereby realizing the change of position restriction and free release of the head product 9. The operation is simpler and can be more convenient for the head product 9 made of soft or hard materials.

[0048] Figure 2 and Figure 4 In the embodiment, a through hole is provided at the bottom of the lower fixing seat 4, and the through hole of the lower fixing seat 4 is used to discharge the air inside the lifting block.

[0049] The through hole at the bottom of the lower fixing seat 4 can discharge the air inside the mounting block when the pull rod 2 moves downward, and can inhale part of the air when the pull rod 2 moves upward, thereby avoiding affecting the movement of the pull rod 2.

[0050] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
