The gas inside the pneumatic telescopic rod 422 will pass through the oblique moving block 423 into the insertion tube 425, and then enter the gas collecting box 427 through the insertion tube 425. Since the magnetic plate 424 is magnetically connected to the oblique moving block 423, when the pneumatic telescopic rod 422 contracts, the oblique moving block 423 will not move.

When positioning plate A41 and positioning plate B42 are close to each other, the rope is initially squeezed and fixed, and at the same time, the positioning block 421 is squeezed and moved, and the oblique block 423 moves accordingly and fixes the rope passing through the through hole 426. At the same time, the gas in the pneumatic telescopic rod 422 will enter the pneumatic telescopic push rod 428 and stretch it, thereby fixing the end of the rope with the clamp 429.

[0037] A groove A411 is provided on one side of the positioning plate A41, and a groove B4211 is provided on one side of the positioning block 421. The groove A411 is opposite to the groove B4211, and the groove diameter of the groove A411 is smaller than the groove diameter of the groove B4211. When the rope is clamped and fixed by the positioning plate A41 and the positioning block 421, the groove A411 and the groove B4211 will contact the surface of the rope, so that the rope can be stuck in the groove A411 and the groove B4211.

[0038] The displacement assembly 7 includes a displacement plate 71 arranged between the two groups of side plates 3, a panel 75 embedded in the upper surface of the displacement plate 71, a threaded barrel 74 fixedly installed on the upper surface of the panel 75, and an extended threaded rod 76 threadedly connected to the inside of the threaded barrel 74, one end of the extended threaded rod 76 is transmission-connected to the drive assembly 8, and mounting grooves 72 are provided on both sides of the displacement plate 71.

The displacement plate 71 is slidingly connected to the sliding groove 31 provided on the outer surface of the side plate 3 through the rolling wheels 73. The drive of the drive assembly 8 causes the extended threaded rod 76 to rotate, thereby causing the threaded barrel 74 to move up and down, thereby driving the displacement plate 71 to move up and down along the sliding groove 31.

[0039] The driving assembly 8 includes a top plate 87 arranged between the two groups of side plates 3, a driving motor 81 fixedly installed on the lower bottom surface of the top plate 87, a driving shaft 82 arranged at the output end of the driving motor 81, a transmission wheel A83 arranged on the outer surface of the driving shaft 82, and a transmission wheel B84 arranged above the top plate 87. A transmission belt 85 is arranged on the outer surfaces of the transmission wheel A83 and the transmission wheel B84. The transmission wheel A83 and the transmission wheel B84 are arranged in the same horizontal plane. When the driving motor 81 is started, its output end drives the transmission wheel A83 to rotate. The rotating transmission wheel A83 will cause the transmission belt 85 to rotate, and then the transmission wheel B84 will rotate.

[0040] An upper push rod 86 is fixedly installed on the upper surface of the top plate 87, and an annular groove is opened on the lower bottom surface of the transmission wheel B84. There are three groups of upper push rods 86, which are arranged equidistantly. One end of the three groups of upper push rods 86 are in contact with the annular groove.

When the pneumatic telescopic rod 422 is compressed to the limit, the squeezing continues at this time, and the oblique block 423 will get rid of the adsorption of the magnetic plate 424, so that the oblique block 423 moves accordingly, and the radian plate 4231 is used to fix the rope passing through the through hole 426. At the same time, the gas in the pneumatic telescopic rod 422 will enter the pneumatic telescopic push rod 428 and stretch it, so that the end of the rope is fixed by the clamp 429, and the rope to be tested is fixed in a curved winding manner, so as to improve the firmness of the rope to be tested and prevent the rope from falling off and the connection from breaking during work. Example

[0042] In order to solve the technical problem of how to improve the detection accuracy, such as Figure 8 and Fig. 9 As shown, the following preferred technical solutions are provided:

[0043] A maintenance component 9 is provided on the outer surface of the side plate 3. The maintenance component 9 is arranged above the displacement plate 71. At the same time, the maintenance component 9 is opposite to the sliding groove 31. The maintenance component 9 includes a storage box 91 embedded in the side plate 3, an injection pipe 92 provided on the outer surface of the storage box 91, and a filter plate 93 provided inside the storage box 91. Lubricating oil is added to the storage box 91 through the injection pipe 92. The filter plate 93 is for preventing impurities generated after the lubricating oil is placed for a long time from sinking to the bottom.

[0044] A positioning sleeve 96 is fixedly installed inside the sliding groove 31, and a guide tube 97 is movably sleeved inside the positioning sleeve 96. A rubber cover 98 is fixedly installed at the lower end of the guide tube 97. An oil overflow hole is opened on the inner wall of the rubber cover 98. The rubber cover 98 is opposite to the rolling wheel 73. An oil inlet hole 971 is opened on the outer surface of the guide tube 97. A bottom groove is opened at the bottom of the storage box 91. A pressure valve 911 is arranged in the bottom groove. The bottom groove is opposite to the guide tube 97. The oil inlet hole 971 is opened at the pipe head of the guide tube 97. During the upward movement of the shift plate 71, the rolling wheel 73 will touch the rubber cover 98, so that the rubber cover 98 drives the conduit 97 to move upward until one end of the conduit 97 passes through the pressure valve 911 and extends into the storage box 91, thereby pushing the filter plate 93 upward. The filter plate 93 can move impurities in the lubricating oil upward. At the same time, the lubricating oil in the storage box 91 enters the conduit 97 through the oil inlet hole 971, and then enters the rubber cover 98 from the conduit 97, and finally comes out from the oil overflow hole and is contaminated to the surface of the rolling wheel 73.

[0045] A support rod 94 is fixedly installed on one side of the storage box 91, and a rubber pad 95 is fixedly installed on the lower end of the support rod 94. During the upward movement of the displacement plate 71, the rubber pad 95 can prevent the displacement plate 71 from moving up beyond the range. Two groups of positioning components 4 are respectively connected to the displacement plate 71 and the mounting seat 2. One group of positioning components 4 moves up and down with the displacement plate 71, and the other group of positioning components 4 is fixed to the mounting seat 2, thereby realizing the tension detection of the rope.

[0046] Specifically, during the working process, as the displacement plate 71 moves upward each time, the rolling wheel 73 will touch the rubber cover 98, so that the rubber cover 98 drives the conduit 97 to move upward until one end of the conduit 97 passes through the pressure valve 911 and extends into the storage box 91. At this time, one end of the conduit 97 will push the filter plate 93 upward, but at this time the oil inlet hole 971 has not entered the storage box 91, nor has it contacted the lubricating oil inside it. The conduit 97 is moved upward again. At this time, the oil inlet hole 971 is connected with the lubricating oil, and the lubricating oil enters the conduit 97, and then enters the rubber cover 98 from the conduit 97, and finally comes out from the oil overflow hole and is contaminated to the surface of the rolling wheel 73, thereby making the surface of the rolling wheel 73 more lubricated, reducing the friction between the rolling wheel 73 and the sliding groove 31, thereby improving the detection accuracy, and also making the movement of the displacement plate 71 smoother, thereby improving work efficiency.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
