[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1 to 5 , the utility model provides a technical solution:

[0028] A nylon rope torsion resistance detector comprises a measuring platform 1, a driving motor 2 is fixedly mounted on the measuring platform 1, a first vertical plate 4 is also fixedly mounted on the measuring platform 1, a transmission mechanism 3 with a deceleration effect is arranged on the driving motor 2 and the first vertical plate 4, a turntable 6 is arranged on the transmission mechanism 3, a group of fixing mechanisms 7 capable of clamping the nylon rope is fixedly arranged on the outer surface of the turntable 6, a counting mechanism 5 rotating with the turntable 6 using the same axis is arranged on the transmission mechanism 3, and the counting mechanism 5 is convenient for reminding when the turntable 6 rotates an angle, a second vertical plate 8 is also fixedly mounted on the measuring platform 1, and a group of fixing mechanisms 7 is also arranged on the second vertical plate 8.

[0029] The transmission mechanism 3 includes a first transmission wheel 31, a second transmission wheel 32, a shaft 33 and a belt 34. The output end of the driving motor 2 is fixedly connected to the first transmission wheel 31. The shaft 33 is rotatably installed on the first vertical plate 4. The outer surface of the shaft 33 is fixedly sleeved with a second transmission wheel 32 used in conjunction with the first transmission wheel 31. The outer surfaces of the first transmission wheel 31 and the second transmission wheel 32 are sleeved with the same belt 34.

[0030] The size of the first transmission wheel 31 is smaller than that of the second transmission wheel 32 .

[0031] By adopting the above technical solution, when it is necessary to test the torsion resistance of the nylon rope after production, first tie the nylon rope to the fixing mechanism 7 of the first vertical plate 4 and the second vertical plate 8, then start the drive motor 2, and the drive motor 2 will slow down the rotation speed through the transmission mechanism 3. At this time, the drive motor 2 will drive the first transmission wheel 31 to rotate, and the belt 34 on the surface of the first transmission wheel 31 will drive the second transmission wheel 32 to rotate. Due to the fixation of the first vertical plate 4, the fixing mechanism 7 is rotated through the shaft 33, thereby realizing the action of twisting the nylon rope. In the process of the nylon rope twisting the entire turntable 6, the counting mechanism 5 can more clearly record the value of each rope breaking, which greatly reduces the error.

[0032] Specifically, Figures 1 to 4 As shown, the counting mechanism 5 includes a counting disk 51 fixedly mounted on the shaft rod 33, a display column 52 fixedly installed on the measuring platform 1, and a slide groove 53 is opened inside the display column 52, a slide rod 54 and a push rod 57 fixedly connected to the slide rod 54 are movably arranged in the slide groove 53, a first contact block 58 used in conjunction with the push rod 57 is also movably arranged in the slide groove 53, a second contact block 59 used in conjunction with the first contact block 58 is fixedly arranged inside the display column 52, a spring 56 is arranged in the slide groove 53, and one end of the spring 56 is fixedly connected to the inner wall of the slide groove 53, and the other end of the spring 56 is fixedly connected to the slide rod 54, a short rod 55 is movably arranged inside the slide rod 54, and one end of the short rod 55 extending outside the slide rod 54 is fixedly connected to the inner wall of the slide groove 53, and the spring 56 is sleeved on the outer surface of the short rod 55.

[0033] The outer surface of the counting disk 51 is provided with a circle of teeth, and the teeth in the teeth row are arranged obliquely. The teeth row is provided with eighteen teeth in total. The end of the sliding rod 54 close to the counting disk 51 is semicircular in design and cooperates with the teeth row on the counting disk 51.

[0034] An LED lamp 9 is arranged at the top of the outer surface of the display column 52. The first contact block 58, the second contact block 59 and the LED lamp 9 are electrically connected to an external power supply. The width of the push rod 57 is smaller than the width of the second contact block 59, and the top of the push rod 57 is inclined.

[0035] By adopting the above technical solution, when the driving motor 2 drives the counting mechanism 5 to work through the transmission mechanism 3, first the counting disk 51 will rotate counterclockwise with the rotation of the shaft 33. During the rotation of the counting disk 51, the inclined tooth row will contact the slide bar 54, and then the slide bar 54 will shrink into the slide groove 53 as the counting disk 51 rotates and the tooth row is squeezed. When the slide bar 54 shrinks into the slide groove 53, the slide bar 54 squeezes the spring 56 to shrink. At this time, the short rod 55 will enter the slide bar 54 as the slide bar 54 enters the slide groove 53. At the same time, when the slide bar 54 moves into the slide groove 53, it moves with the push rod 57 in the slide groove 53, and then the inclined end of the top of the push rod 57 will push the first contact block 58 moves upward in the slide groove 53, so that the first contact block 58 contacts the second contact block 59, and the power is turned on. At this time, the LED light 9 is on, and then because the tooth row is not in contact with the slide bar 54, the contracted spring 56 rebounds to make the slide bar 54 move back in the slide groove 53 with the push rod 57, and the first contact block 58 will drop due to gravity and separate from the second contact block 59, and then the LED light 9 will go out, achieving the effect of the LED light 9 flashing. It only needs to count the number of times the LED light 9 is on to get the measurement result. The counting method is simpler and more convenient, and the eighteen teeth of the tooth row can make the turntable 6 twist the nylon rope, and make one turn with a measurement point every twenty degrees, so the measurement accuracy is higher on the original basis.

[0036] Specifically, Figure 1 and Figure 5 As shown, one end of the shaft rod 33 is fixedly connected to the turntable 6, and the fixing mechanism 7 includes a first clamping plate 71, a second clamping plate 72, a lifting ring 73 and a threaded hand rod 74. The second clamping plate 72 is fixedly installed on the outer surfaces of the turntable 6 and the second vertical plate 8. The first clamping plate 71 is movably provided on the outer surfaces of the turntable 6 and the second vertical plate 8. A lifting ring 73 fixedly installed on the outer surface of the turntable 6 is provided between the first clamping plate 71 and the second clamping plate 72. A threaded hand rod 74 is rotatably provided on the second clamping plate 72. The threaded hand rod 74 passes through the first clamping plate 71 and is threadedly installed with the first clamping plate 71.

[0037] The first clamping plate 71 and the second clamping plate 72 are both provided with rope grooves 10 matching with the nylon rope.

[0038] By adopting the above technical solution, when clamping the nylon rope, the original equipment fixes one end of the nylon rope through the tip, but this will make the distribution of the entire nylon rope uneven. When twisting the nylon rope, the part of the nylon rope clamped by the tip will be scattered around the tip part, and the diameter of this part of the rope will also be reduced. As a result, when twisting the nylon rope, the tip part is likely to break first, which will cause a large error in the measurement result. At this time, when using the fixing mechanism 7 to clamp the rope, first tie the nylon rope at the ring 73, place the untied end of the nylon rope in the rope groove 10, and twist the threaded hand lever 7. The first clamping plate 71 moves downward along the thread of the threaded handle 74 and gradually approaches the second clamping plate 72, thereby clamping the nylon rope, and fixing the two ends of the nylon rope on the fixing mechanism 7 of the first vertical plate 4 and the second vertical plate 8 according to the above operation, which can effectively reduce the situation that the clamping part will break first due to the clamping problem when the nylon rope is subjected to torsion resistance testing, resulting in low measurement accuracy. In addition, due to the effect of the rope grooves 10 on the first clamping plate 71 and the second clamping plate 72, the force on the lifting ring 73 can be effectively relieved, reducing the situation that the lifting ring 73 is broken due to excessive torque, and further improving the measurement accuracy.

[0039] Working principle: When it is necessary to test the torsion resistance of the produced nylon rope, first tie the nylon rope to the fixing mechanism 7 of the first vertical plate 4 and the second vertical plate 8, then start the drive motor 2, and the drive motor 2 slows down the speed through the transmission mechanism 3, and the belt 34 passing through the surface of the first transmission wheel 31 rotates the second transmission wheel 32. Due to the fixation of the first vertical plate 4, the fixing mechanism 7 is rotated through the shaft 33, thereby realizing the action of twisting the nylon rope. In the process of the nylon rope twisting the entire turntable 6, the value of each rope breaking can be recorded more clearly through the counting mechanism 5. It only needs to count how many times the LED light 9 lights up to get the measurement result. The counting method is simpler and more convenient, and the eighteen teeth of the tooth row can make the turntable 6 twist the nylon rope to rotate one circle with a measurement point every twenty degrees. The measurement accuracy is higher on the original basis, and the error is greatly reduced.

[0040] When the fixing mechanism 7 clamps the rope, the nylon rope is first knotted at the eye 73, and the untied end of the nylon rope is placed in the rope groove 10. The threaded hand rod 74 is turned to make the first clamping plate 71 move down along the thread of the threaded hand rod 74 and gradually approach the second clamping plate 72, and then clamp the nylon rope. The two ends of the nylon rope are fixed to the fixing mechanism 7 of the first vertical plate 4 and the second vertical plate 8 according to the above operation. This can effectively reduce the situation where the clamping part breaks first due to clamping problems during the torsion resistance test of the nylon rope, resulting in low measurement accuracy. In addition, due to the effect of the rope grooves 10 on the first clamping plate 71 and the second clamping plate 72, the force on the eye 73 can be effectively relieved, reducing the situation where the eye 73 breaks due to excessive torque, thereby further improving the measurement accuracy.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
