[0002] Shelves are generally composed of support frames and shelves. The outside of the shelves is provided with a frame fixedly connected to the support frame. The shelves are fixed by the frame. Generally, the load-bearing capacity of the shelves is determined based on the structural strength of the frame and the connection strength of the parts between the frame and the support frame.

[0003] When conducting load-bearing capacity tests on existing smart storage shelves, vertical pressure is applied directly to the shelf frame after the shelf is fixed and its deformation is observed. However, due to the different tightening degrees of the bolts between the support frame and the base of each shelf during assembly or other assembly factors, the parallelism between the four support frames of the shelf is inconsistent, resulting in the shelf not being placed horizontally, the side frames of the shelf being subjected to inconsistent forces when subjected to vertical pressure, and the support frame is easily deformed, which affects the test results of the shelf load-bearing capacity.

[0055] The No. 1 driving rod 81 is fixedly connected to the telescopic end of the No. 2 driving rod 11, and the telescopic end of the No. 1 driving rod 81 is fixedly connected to a limiting plate 82. The limiting plate 82 is rotatably connected to four transmission rods 83. A clamping assembly 85 is provided between the transmission rod 83 and the limiting plate 82.

The transmission rod 83 is provided with a guide rail 84 along the length direction. The telescopic ends of the No. 2 telescopic rod 10 are slidably connected in the guide rail 84 on one side of the transmission rod 83.

[0056] In this embodiment, the No. 1 driving rod 81 is started to extend, and at this time, the No. 1 driving rod 81 pushes the limit plate 82 to move downward, and the limit plate 82 pushes the corresponding No. 2 telescopic rod 10 through the four transmission rods 83 connected thereto, and the telescopic ends of all No. 2 telescopic rods 10 are extended, and downward pressure is applied to the four L-shaped sleeves 61 through the four No. 2 telescopic rods 10, and all L-shaped sleeves 61 drive the pressure mechanism 7 connected thereto to press down the layer frame;

[0057] When all the clamping assemblies 5 move, all the clamping assemblies 5 synchronously drive all the second telescopic rods 10 to move, and all the second telescopic rods 10 simultaneously drive all the L-shaped sleeves 61 to move to the same position, and all the transmission rods 83 can be adjusted synchronously with the second telescopic rod 10.

[0062] In this embodiment, when the No. 1 driving rod 81 pushes all the pressure mechanisms 7 downward, if the stop valve 93 does not close the rubber tube 94, all the No. 1 telescopic rods 73 can shrink automatically after hitting the shelf frame, so that when the vertical heights of the frames are different, all the rotating seats 752 can keep in contact with the upper end surface of the frame, and then the rubber tube 94 is closed through the stop valve 93. At this time, the No. 1 driving rod 81 continues to push the pressure mechanism 7 downward, and the fixed sleeves of all the No. 1 telescopic rods 73 remain connected under the connection of the rubber tube 94. Under the action of the hydraulic oil, even if the shelf frame is deformed, all the rotating seats 752 can always maintain the same downward pressure on all shelf frames.

A clamp 53 is provided on one side of the fixing seat 52 , and a retractable electric telescopic rod 54 is fixedly connected between the fixing seat 52 and the clamp 53 .

[0065] In this embodiment, after the clamp 53 and the fixing seat 52 are sleeved on the outside of the support frame, the electric telescopic rod 54 is started to retract, and the electric telescopic rod 54 drives the clamp 53 and the fixing seat 52 to clamp the support frame and correct the verticality of the support frame.

[0067] The screw rod 21 is fixedly connected to the base 1 , a positioning plate 22 is sleeved on the outside of the screw rod 21 , and a bolt 23 is threadedly connected to the screw rod 21 , and the bolt 23 can limit the positioning plate 22 .

[0068] The shelf base 1 is limited by the positioning plate 22 , and the positioning plate 22 is limited by the bolts 23 .

[0069] Working principle:

[0070] The shelf is placed on the base 1, and then the shelf base 1 is fixed at the center position of the base 1 by the positioning component 2; then the No. 2 driving rod 11 is started to extend, and the No. 2 driving rod 11 drives all the clamping components 5 to move down to the top of the shelf support frame, and the No. 3 driving rod 12 is started to extend and retract, and the No. 3 driving rod 12 drives the two rotating rods 4 to move relatively, and the two electric telescopic sleeves 13 at both ends of one rotating rod 4 are started to extend and retract, and the two electric telescopic sleeves 13 can push the sliding sleeves 51 connected thereto to slide along the rotating rod 4 at the same time. At this time, under the cooperation of all L-shaped sleeves 61 and connecting rods 62, all sliding sleeves 51 slide along the rotating rod 4 at the same time; through the drive of the No. 3 driving rod 12 and the electric telescopic sleeve 13, the positions of all the clamping components 5 can be adjusted synchronously, so that all the clamping components 5 are directly above the shelf support frame, which is convenient for limiting the shelf support frames of different sizes;

[0071] Then, the second driving rod 11 is started to extend, and the second driving rod 11 drives all the clamping components 5 to be set on the outside of the corresponding shelf support frame, and at the same time, the electric telescopic rod 54 is started to retract, and the electric telescopic rod 54 drives the clamp 53 and the fixing seat 52 to clamp the support frame and correct the verticality of the support frame;

[0072] Push the sliding seat 71, and the sliding seat 71 slides along the length direction of the rotating rod 4, so as to locate the pressing position of the connecting assembly 75, and then rotate the positioning screw 76 to fix the sliding seat 71 and the rotating rod 4 through the positioning screw 76;

[0073] Start the No. 1 driving rod 81 to extend, at this time the No. 1 driving rod 81 pushes the limit plate 82 to move downward, the limit plate 82 pushes the corresponding No. 2 telescopic rod 10 through the four transmission rods 83 connected thereto, the telescopic ends of all No. 2 telescopic rods 10 extend, and downward pressure is applied to the four L-shaped sleeves 61 through the four No. 2 telescopic rods 10. Since all the L-shaped sleeves 61 are located at the nodes where all the connecting rods 62 are connected, the uniformity of the overall force of the limit assembly 6 can be improved, and the uniformity of the force of all the pressure mechanisms 7 on the L-shaped sleeves 61 can be improved, so as to ensure that all the pressure mechanisms 7 apply the same downward pressure to the layer frame, thereby improving the accuracy of the layer bearing capacity test;

[0074] All L-shaped sleeves 61 are located at the lower side of the clamping assembly 5, so that all L-shaped sleeves 61 are close to the support frame fixed on one side. When the transmission rod 83 applies vertical pressure to the L-shaped sleeve 61, the horizontal component force on the support frame can be reduced, and the vertical support stability of the support frame can be maintained;

[0075] All pressure mechanisms 7 are connected to a hydraulic assembly 9, which enables all pressure mechanisms 7 to maintain the same downward pressure on each part of the frame of the upper layer of the shelf, thereby improving the accuracy of the layer bearing capacity test;

[0076] When the No. 1 driving rod 81 pushes all the pressure mechanisms 7 downward, if the stop valve 93 does not close the rubber tube 94, all the No. 1 telescopic rods 73 can shrink automatically after touching the shelf frame, so that when the vertical heights of the frames are different, all the rotating seats 752 can keep in contact with the upper end surface of the frame, and then the rubber tube 94 is closed through the stop valve 93. At this time, the No. 1 driving rod 81 continues to push the pressure mechanism 7 downward, and the fixed sleeves of all the No. 1 telescopic rods 73 remain connected under the connection of the rubber tube 94. Under the action of the hydraulic oil, even if the shelf frame is deformed, all the rotating seats 752 can always maintain the same downward pressure on all shelf frames.
