Secondly, the detection line of the existing tester is very long, and there is no mechanism for collecting the line on the tester. The line of the specified length cannot be released according to actual use requirements, so the line will be dragged on the ground during use and is easily damaged. Therefore, the utility model proposes a fully automatic reversing static load tester. Utility Model Content

[0025] like Figure 1-Figure 2 As shown, the wire winding assembly 3 includes a cylinder 31, and the top of the cylinder 31 is an open design. The detection line 4 is wound on the surface of the cylinder 31, and one end of the detection line 4 passes through the reserved opening on the side wall of the cylinder 31 and extends to the inside of the cylinder 31. The bottom wall of the cylinder 31 passes through and is fixedly connected with a vertical axis 33, and the bottom and top ends of the vertical axis 33 are rotatably connected to the inner bottom wall of the U-shaped plate 2 and the lower surface of the tester main unit 1 respectively.

[0026] Therefore, the cylinder 31 can rotate inside the U-shaped plate 2 via the vertical axis 33 , thereby winding up or unwinding the detection line 4 .

[0027] like Figure 1-Figure 2 As shown, an annular baffle 32 is fixedly connected to the bottom end and the top end of the outer wall of the cylinder 31.

[0028] The annular baffle 32 can prevent the detection line 4 from being separated from the cylinder 31 when it is wound on the surface of the cylinder 31 .

[0029] like Figure 1-Figure 3 As shown, the driving assembly 5 includes a horizontal shaft 51 rotatably connected to the inner wall of the U-shaped plate 2, and an active bevel gear 52 is fixedly connected to one end of the horizontal shaft 51 close to the vertical shaft 33, and a driven bevel gear 34 is fixedly connected to the top of the vertical shaft 33, and the active bevel gear 52 is meshed with the driven bevel gear 34.

[0030] Through the meshing of the active bevel gear 52 and the driven bevel gear 34 , the rotation of the horizontal shaft 51 will drive the vertical shaft 33 to rotate synchronously, and finally realize the rotation of the cylinder 31 .

[0031] like Figure 3 As shown, the first protective cover 6 is located on the surfaces of the driving bevel gear 52 and the driven bevel gear 34 .

[0032] The first protective cover 6 can protect the driving bevel gear 52 and the driven bevel gear 34 to prevent soil from contaminating the driving bevel gear 52 and the driven bevel gear 34 .

The top ends of the support rods 82 are fixedly connected with connecting sleeves 83 , which are sleeved on the surfaces of the base feet 81 .

[0038] The U-shaped plate 2 can be supported by the support assembly 8 so that the lower surface of the U-shaped plate 2 does not directly contact the ground, thereby ensuring that the tester host 1 and the U-shaped plate 2 are not contaminated during use.

[0039] Working principle: When using the tester, first remove the support rod 82 of the support assembly 8 from the arc-shaped holder 9, then put the connecting sleeve 83 on the top of the support rod 82 on the foot 81, then put the tester in the specified position, support it with the support rod 82, and then turn the hand wheel 56 to drive the cylinder 31 to rotate, unwind the detection line 4, and pull the detection line 4 during the unwinding process. When the detection line 4 is unwound to the specified length, stop turning the hand wheel 56, and then insert one end of the detection line 4 through the inside of the cylinder 31 into the interface of the tester host 1, and connect the other end to the hydraulic equipment to start the test. After use, turn the hand wheel 56 in the opposite direction to drive the cylinder 31 to rotate, so as to rewind the detection line 4.
