Description

Technical Field

[0001] The utility model belongs to the technical field of new energy batteries, and in particular relates to a lifting tool frame for an energy storage container. Background Art

[0002] With the rapid development of the electrochemical energy storage industry, its share in the new energy industry continues to increase, and the installed capacity of energy storage containers with high modularity, easy transportation and installation is also steadily increasing. In the process of energy storage containers from sheet metal frames to finished products, their transportation within the assembly plant is mainly achieved by AGV carts.

[0003] The transportation process is as follows: first, the crane lifts the container frame onto the tooling rack supported by the AGV trolley; secondly, the AGV trolley transports the container and the tooling rack to the workstation for assembling each module; finally, the AGV trolley transports the container and the tooling rack to the finished product area.

[0004] In order to move the container, the AGV car lowers its height through its own hydraulic system, drives under the tooling rack, and then rises again after it stabilizes to lift the tooling rack and the container. When the container needs to be put down at the designated location, the AGV car lowers its height and drives out of the tooling rack.

[0005] At present, the AGV car is equipped with a hydraulic lifting system, but this solution has the following disadvantages:

[0006] 2.1 The cost of AGVs used for transportation is relatively higher when equipped with a hydraulic lifting system, and there are fewer types to choose from, which will not be conducive to achieving cost reduction and efficiency improvement.

[0007] 2.2 The AGV cart equipped with a hydraulic lifting system has its hydraulic system installed on the wheel axle. It has a compact and complex structure, which makes it difficult to repair when it is needed. In addition, there are usually fewer AGV carts in the assembly plant. When it needs to be repaired and taken offline, the time cost will be significantly increased.

[0008] 2.3 If the hydraulic system of the AGV fails suddenly during the lifting, lowering and transportation process, the container and the tooling rack may directly hit or scratch the ground, causing safety accidents and property losses. Utility Model Content

The lifting units 2 are fixedly connected to the tool frame 1. The lifting units 2 can be telescopically adjusted in a vertical direction to push against the ground.

[0034] The utility model provides a lifting fixture frame for energy storage containers. Compared with the prior art, the utility model includes a fixture frame 1 and a plurality of lifting units 2. The plurality of lifting units 2 are fixedly connected to the fixture frame 1. The lifting units 2 can be telescopically adjusted in the vertical direction to push against the ground. The lifting units 2 are started to raise the height between the fixture frame 1 and the ground. The AGV trolley drives into the space between the fixture frame 1 and the ground so that the fixture frame 1 falls on the AGV trolley, and the AGV trolley lifts the fixture frame 1 and the container. When the fixture frame 1 needs to be transported, the lifting unit 2 is controlled so that the piston rod of the lifting unit 2 is away from the ground. At the same time, the movement of the AGV trolley is controlled to realize the transfer and transportation of the fixture frame 1 and the container. By providing the lifting unit 2 on the fixture frame 1, the technical problems of high cost and few types of AGV trolleys equipped with a hydraulic lifting system in the prior art are solved.

[0035] In some embodiments, the tooling frame 1 includes a table 11, a plurality of cross bars 12, and a plurality of connecting rods 13. The plurality of cross bars 12 are arranged below the table 11, the cross bars 12 are fixedly connected to the table 11, the plurality of cross bars 12 are arranged at intervals along the length direction of the table 11, and the cross bars 12 are parallel to the width direction of the table 11; the plurality of connecting rods 13 are arranged below the table 11, the connecting rods 13 are fixedly connected to the table 11, the plurality of connecting rods 13 are arranged at intervals along the width direction of the table 11, and the connecting rods 13 are parallel to the length direction of the table 11; wherein the cross bars 12 and the connecting rods 13 are fixedly connected to each other.

[0036] By providing a plurality of connecting rods 13 and a plurality of cross bars 12 at the bottom of the table 11, the strength of the tooling frame 1 can be enhanced to prevent the tooling frame 1 from bending due to force during the transportation process, thereby preventing the container on the table 11 from falling off.

[0037] Furthermore, the table top 11 can be divided into multiple areas to facilitate the placement of containers in different areas.

[0038] In some embodiments, the tooling frame 1 further includes:

[0039] A plurality of legs 14 are vertically arranged below the table 11, one end of the legs 14 is fixedly connected to the connecting rod 13, and the plurality of legs 14 are arranged at intervals;

[0040] A plurality of groups of struts 15 are arranged one-to-one corresponding to the supporting legs 14. The group of struts 15 includes two struts 15. The two struts 15 are respectively arranged on both sides of the supporting legs 14, and one end of the strut 15 is connected to the connecting rod 13, and one end of the strut 15 is connected to the side of the supporting leg 14. The strut 15 and the supporting leg 14 are arranged at an angle.

[0041] Support rods 15 are provided on both sides of the legs 14 to enhance the connection strength between the legs 14 and the connecting rod 13 so that the connecting rod 13 does not bend during the support of the legs 14 , thereby further improving the safety of the tooling frame 1 .

[0042] Furthermore, the lifting unit 2 adopts a hydraulic cylinder, an electric push rod or a pneumatic cylinder.

[0043] In some embodiments, the lifting unit 2 adopts a hydraulic cylinder, and the tooling frame 1 is also provided with a pump, and the pump is connected to the hydraulic cylinder through a hydraulic pipeline.

[0045] The lifting of the hydraulic cylinder is controlled by controlling the opening or closing of the pump, and the pump is connected to multiple hydraulic cylinders at the same time, which improves the stability of the tooling frame 1 during operation. The overflow valve and the safety valve are arranged on the hydraulic pipeline to improve the safety during use.

[0046] A rubber pad 16 is provided at the bottom of the leg 14 to increase the friction between the leg 14 and the ground and prevent the leg 14 from directly hitting the ground during placement, causing the tooling frame 1 to shake, thereby causing the container to shake.

[0047] In some other embodiments, the hydraulic cylinder is connected to the support leg 14 by bolts. The bolt connection structure is used to facilitate the maintenance and replacement of the hydraulic cylinder.

[0048] The hydraulic cylinder adopts a single-acting hydraulic cylinder, and the pump adopts a single-acting electric pump 3.

[0049] Compared with double-acting hydraulic cylinders, single-acting hydraulic cylinders require fewer seals. They have a simple structure, are easy to maintain, and have low costs. Because there is only one interface, the number of valves and hydraulic lines can be reduced.

[0050] The single-acting electric pump 3 cooperates with the internal synchronous diverter valve to control the synchronous extension and contraction of multiple single-acting hydraulic cylinders. The single-acting electric pump 3 is externally mounted on the front side of the tooling frame 1, which is convenient for maintenance and installation of pipelines without affecting transportation.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
