[0033] It should be noted that when the tension detection device detects the middle part of the wire rope, it is necessary to open the movable mounting structure 2 to allow the wire rope to enter the interior of the detection box 1, and then allow the wire rope to enter the arc-shaped groove of the guide wheel 7 and the pushing wheel 6. At this time, the movable mounting structure 2 can be closed. When the movable mounting structure 2 is closed, the cylinder 4 can be started to work. When the cylinder 4 is working, it can push the pushing wheel 6 to move. When the pushing wheel 6 moves, it can squeeze the wire rope. The tension Fs of the wire rope will be reflected on the force sensor 3 with a certain geometric relationship. The value obtained on the force sensor 3 can directly reflect the size of the tension Fs on the wire rope. When the specifications of the wire rope are different, the replacement structure 8 can be operated to replace the pushing wheel 6 and the guide wheel 7. After the pushing wheel 6 and the guide wheel 7 are replaced, their arc-shaped grooves can be matched with the wire rope.

[0034] like Figure 2 , Figure 5 and Figure 6 As shown, the movable installation structure 2 includes: a slot 201, the slot 201 is opened at the front of the detection box 1, a first guide slot 202 is opened inside the slot 201, and limit slots 203 are opened on both the upper and lower sides of the slot 201. A fixing rod 204 is fixedly connected to the front of the detection box 1, and a positioning groove 205 is opened on the surface of the fixing rod 204. A limit block 206 is movably connected to the inner side of the limit slot 203, and a plug plate 207 is fixedly connected between the limit blocks 206. A second guide groove 208 is provided at the end of the plug plate 207 of the groove 202, a closing plate 209 is fixedly connected between the plug plates 207, a rotating shaft 210 is fixedly connected to the closing plate 209, a connecting arm 211 is rotatably connected to the rotating shaft 210, a clamping groove 212 is provided at the end of the connecting arm 211, a clamping plate 213 is fixedly connected to the end of the connecting arm 211, a fixing groove 214 is penetrated through the surface of the closing plate 209, and a fixing rod 204 is movably connected inside the fixing groove 214.

[0035] It is worth noting that pulling the detection box 1 can drive the slot 201 to dock with the wire rope, and pushing the detection box 1 can make the slot 201 and the wire rope slide. When the wire rope slides to the inside of the first guide groove 202, the wire rope can be placed in the arc-shaped groove of the pushing wheel 6 and the guide wheel 7. At this time, the closing plate 209 can be pulled to drive the plug plate 207 and the limit block 206 to dock with the slot 201 and the limit groove 203. Pushing the closing plate 209 can make the plug plate 207 and the limit block 206 slide with the slot 201 and the limit groove 203. When the plug plate 207 and the limit block 206 slide to the end of the slot 201 and the limit groove 203, the plug plate 207 can drive the second guide groove 208 to dock with the first guide groove 202, and the closing plate 2 When 09 moves, it can drive the fixed groove 214 and the fixed rod 204 to slide. When the fixed groove 214 slides to the bottom end of the fixed rod 204, the connecting arm 211 can be pulled. When the connecting arm 211 is pulled, it can rotate through the rotating shaft 210. When the connecting arm 211 rotates, it can drive the card plate 213 to rotate. When the card plate 213 rotates, it can squeeze the positioning groove 205. When the card plate 213 is squeezed, it can be deformed by its own plastic material. When the card plate 213 is deformed, the positioning groove 205 can be squeezed into the inside of the card slot 212. At this time, the card plate 213 can be reset by its own plastic material. After the card plate 213 is reset, it can be engaged with the positioning groove 205, so that the tension detection device can be quickly installed on the wire rope.

[0036] like Figure 3 and Figure 4 As shown, the replacement structure 8 includes: a first connecting block 801, which is fixedly connected to the sides of the driving wheel 6 and the guide wheel 7 respectively, and a socket 802 is penetrated on the first connecting block 801, a slide rail 803 is fixedly connected to the bottom of the mounting seat 5, a slide groove 804 is opened on the top of the mounting seat 5, and the slide rail 803 is movably connected inside the slide groove 804, and a second connecting block 805 is fixedly connected to the side of the mounting seat 5, and a plug rod 806 is fixedly connected to the second connecting block 805, and the side of the plug rod 806 is movably connected to the inside of the socket 802, and an extrusion groove 807 is opened on the surface of the plug rod 806, and positioning blocks 808 are movably connected on both sides of the extrusion groove 807, and springs 809 are fixedly connected between the positioning blocks 808.

[0037] It can be understood that when the specifications of the wire rope are different, the pushing wheel 6 and the guide wheel 7 need to be replaced. The positioning block 808 can be pressed to slide through the extrusion groove 807. The spring 809 can be squeezed when the positioning block 808 slides. When the positioning block 808 is squeezed into the extrusion groove 807, the first connecting block 801 can be pulled. When the first connecting block 801 is pulled, the socket 802 can be driven to move. When the socket 802 moves, it can slide through the insertion rod 806. When the first connecting block 801 is pulled, the slide rail 803 can be driven to move. When the slide rail 803 moves, it can slide through the slide groove 804. When the slide rail 803 slides out of the slide groove 804, the pushing wheel 6 and the guide wheel 7 can be replaced.

[0038] Working principle: Figure 1-Figure 6 As shown, when the steel wire rope intermediate tension detection device is used, the tension detection device needs to replace the pushing wheel 6 and the guide wheel 7 according to the specifications of the steel wire rope during use, and the positioning block 808 can slide through the extrusion groove 807 by pressing, and the positioning block 808 can squeeze the spring 809 when sliding, and when the positioning block 808 is squeezed into the extrusion groove 807, the first connecting block 801 can be pulled, and when the first connecting block 801 is pulled, the socket 802 can be driven to move, and when the socket 802 moves, it can slide through the insertion rod 806, and when the first connecting block 801 is pulled, the slide rail 803 can be driven to move, and when the slide rail 803 moves, it can slide through the slide groove 804, and when the slide rail 803 slides out of the slide groove 804, the pushing wheel 6 and the guide wheel 7 can be replaced;

[0039] After the pushing wheel 6 and the guide wheel 7 are replaced, pulling the detection box 1 can drive the slot 201 to dock with the steel wire rope, and pushing the detection box 1 can make the slot 201 and the steel wire rope slide. When the steel wire rope slides to the inside of the first guide groove 202, the steel wire rope can be placed in the arc-shaped groove of the pushing wheel 6 and the guide wheel 7. At this time, the closing plate 209 can be pulled to drive the plug plate 207 and the limit block 206 to dock with the slot 201 and the limit groove 203. Pushing the closing plate 209 can make the plug plate 207 and the limit block 206 slide with the slot 201 and the limit groove 203. When the plug plate 207 and the limit block 206 slide to the end of the slot 201 and the limit groove 203, the plug plate 207 can drive the second guide groove 208 to dock with the first guide groove 202, and the sealing plate 209 can be pulled to drive the plug plate 207 and the limit block 206 to dock with the slot 201 and the limit groove 203. When the closing plate 209 moves, it can drive the fixed groove 214 and the fixed rod 204 to slide. When the fixed groove 214 slides to the bottom end of the fixed rod 204, the connecting arm 211 can be pulled. When the connecting arm 211 is pulled, it can rotate through the rotating shaft 210. When the connecting arm 211 rotates, it can drive the card plate 213 to rotate. When the card plate 213 rotates, it can squeeze the positioning groove 205. When the card plate 213 is squeezed, it can be deformed by its own plastic material. When the card plate 213 is deformed, the positioning groove 205 can be squeezed into the inside of the card groove 212. At this time, the card plate 213 can be reset by its own plastic material. After the card plate 213 is reset, it can be engaged with the positioning groove 205, so that the tension detection device can be quickly installed on the wire rope;

[0040] After the tension detection device is installed, the cylinder 4 can be started to work. When the cylinder 4 is working, it can push the driving wheel 6 to move. When the driving wheel 6 moves, it can squeeze the wire rope. The tension Fs of the wire rope will be reflected on the force sensor 3 with a certain geometric relationship. The value obtained on the force sensor 3 can directly reflect the size of the tension Fs on the wire rope.
