[0026] Example 1

[0027] A rapid cable release hook stress pin calibration device, such as Figures 1 to 4As shown, the device includes a top block 9 whose outer wall is attached to the side wall of the hook body 1 and a limiting plate 3 that abuts against one side of the hook body 2. An adjustable telescopic rod 8 is connected to one side of the top block 9. A rotating connecting seat 4 is fixed to the outer wall of one side of the limiting plate 3. A support rod 5 is rotatably connected to the rotating connecting seat 4. A top plate 6 is fixed to one end of the support rod 5. A split-type hydraulic jack 7 is provided on the outer wall of one side of the top plate 6. The outer wall of the split-type hydraulic jack 7 has two through holes. A limiting rod 17 is inserted into the inner wall of the through hole. Multiple insertion holes are opened on the outer wall of the top plate 6. One end of the limiting rod 17 is inserted into the insertion hole. A slot is opened on the outer wall of one end of the limiting rod 17. The same retaining ring 18 is engaged in the inner wall of the two slots. The telescopic end of the split hydraulic jack 7 abuts against one end of the adjustable telescopic rod 8. The oil pipe joint of the split hydraulic jack 7 is connected to the external oil pump and the high-precision pressure gauge. The high-precision pressure gauge is electrically connected to the data processing unit.

[0028] The adjustable telescopic rod 8 includes a connecting rod 10 and a rotating cylinder 11. One end of the connecting rod 10 is connected to the top block 9. The rotating cylinder 11 is rotatably fitted on the outer wall of the connecting rod 10. The inner wall of the rotating cylinder 11 is fixed with a screw 12. One end of the connecting rod 10 is provided with a threaded hole 13, and the screw 12 is threadedly fitted with the threaded hole 13.

[0029] During testing, the limiting plate 3 is placed on the side of the unhooking hook body 2 near the hook body 1, and the top block 9 is pressed against the side wall of the hook body 1. Then, the split hydraulic jack 7 is placed on one side of the top plate 6, the limiting rod 17 is inserted into the through hole, and the retaining ring 18 is inserted into the retaining groove to fix the split hydraulic jack 7. A worker lifts the split hydraulic jack 7 so that it faces the top block 9, and rotates the rotating cylinder 11, which drives the screw 12 to rotate, causing the rotation... The cylinder 11 and the connecting rod 10 move relative to each other, extending the overall length of the adjustable telescopic rod 8 until the outer wall of one end of the rotating cylinder 11 abuts against the telescopic end of the split hydraulic jack 7, and the position of the split hydraulic jack 7 can be relatively fixed. Then the external oil pump is started, so that the split hydraulic jack 7 applies pressure to the hook body 1 of the cable release hook through the adjustable telescopic rod 8 and the top block 9. The data processing unit reads the pressure gauge data in real time and obtains the force measurement data according to the algorithm system and real-time data.

[0030] By providing an adjustable telescopic rod 8, the length of the adjustable telescopic rod 8 can be adjusted as needed, eliminating the need for multiple adjustment pads, and ensuring that the top block 9 is in close contact with the hook body 1 of the cable release hook, thus guaranteeing the test results.

[0031] By setting a limiting plate 3 and a rotating connecting seat 4, the relative angle between the support rod 5 and the limiting plate 3 can be adjusted, so that the support rod 5 can stably contact the unloading hook body 2 while adapting to the angle of different models of unloading hooks.

[0032] Example 2

[0033] A rapid cable release hook stress pin calibration device, this embodiment is based on embodiment 1, with the following improvements, such as... Figure 3 As shown, a fixing rod 14 is fixed to one side of the outer wall of the top block 9, a slot is opened at one end of the connecting rod 10, and a plug block 15 is fixed to one end of the fixing rod 14. Limiting holes are opened on the side walls of the plug block 15 and the slot, and a limiting pin 16 is inserted into the inner wall of the limiting hole.

[0034] Since the inner wall shape of different release hooks is different, before measurement, prepare a top block 9 that can fit tightly against the inner wall of the release hook body 1, insert the insert block 15 into the slot, and then insert the limiting pin 16 into the limiting hole to fix the top block 9.

[0035] With the fixed rod 14, the insert block 15 and the limiting pin 16, it is easy to replace the top block 9 that can fit tightly against the inner wall of the hook body 1 according to the inner wall of the release hook, making the operation convenient.

[0036] Working principle: During testing, the limiting plate 3 is placed on the side of the unhooking hook body 2 near the hook body 1. The top block 9 is pressed against the side wall of the hook body 1. Then, the split hydraulic jack 7 is placed on one side of the top plate 6. The limiting rod 17 is inserted into the through hole. Then, the retaining ring 18 is inserted into the retaining groove to fix the split hydraulic jack 7. One worker lifts the split hydraulic jack 7 so that it faces the top block 9. The rotating cylinder 11 is rotated, which drives the screw 12 to rotate, causing the rotating cylinder 11 and the connecting rod 10 to move relative to each other, extending the overall length of the adjustable telescopic rod 8 until the rotating cylinder 11... One end of the outer wall of the split hydraulic jack 7 is in contact with the telescopic end of the split hydraulic jack 7, and the position of the split hydraulic jack 7 can be relatively fixed. Then the external oil pump is started, so that the split hydraulic jack 7 applies pressure to the hook body 1 of the cable release hook through the adjustable telescopic rod 8 and the top block 9. The data processing unit reads the pressure gauge data in real time and obtains the force measurement data according to the algorithm system and real-time data. Since the inner wall shape of different cable release hooks is different, before measurement, a top block 9 that can fit tightly with the inner wall of the cable release hook body 1 is prepared. The insert block 15 is inserted into the slot, and then the limiting pin 16 is inserted into the limiting hole to fix the top block 9.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
