When the rope diameter of the steel wire rope is worn, the pressure of the steel wire rope on the connecting piece decreases, so that the reset piece exerts a resilient force on the connecting piece through the moving part, so that the moving part and the connecting piece move to the initial position, and then the distance sensing part moves to the initial position, thereby avoiding the situation that the position of the distance sensing part changes without following the change of the rope diameter, causing the distance sensing part to fail to respond to the change of the rope diameter, and the current value displayed by the proximity switch remains unchanged, so as to ensure that the steel wire rope diameter detection device can detect the change of the rope diameter at different positions of the steel wire rope in real time. In this way, when the rope diameter of the steel wire rope changes, the current value can be used to determine whether the steel wire rope is worn. After the rope diameter of the steel wire rope is worn and becomes thin, the distance sensing part moves away from the proximity switch under the action of the reset piece, and the greater the distance between the proximity switch and the distance sensing part, the greater the current value displayed by the proximity switch. When the actual current value exceeds the preset current value, it can be determined that the rope diameter of the steel wire rope is excessively worn, so that the worker can replace the worn steel wire rope. Through accurate detection of the rope diameter of the steel wire rope, stable operation of the device is ensured, and safety and reliability are improved. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0046] The application will be further described below in conjunction with the drawings and specific embodiments. It should be noted that the description of these embodiments is used to help understand the application, but does not constitute a limitation of the application. The specific structure and functional details disclosed herein are only used to describe the example embodiments of the application. However, the application can be embodied in many alternative forms, and should not be understood as limited in the embodiments described herein.

[0047] As Figure 1 and Figure 2 shown, according to the embodiments of the present disclosure, a steel wire rope diameter detection device 100 is provided, comprising: a connecting piece 110 for abutting to the steel wire rope to be detected, the steel wire rope sliding relative to the connecting piece 110; a moving part 120 connected to the connecting piece 110, in the case of change of the diameter of the steel wire rope, the pressure of the steel wire rope on the connecting piece 110 changes, so that the connecting piece 110 drives the moving part 120 to move; a distance sensing part 130 connected to the moving part 120; a reset piece 140 provided on the moving part 120 for driving the moving part 120 to move to the initial position; a proximity switch 150 for displaying the current value in real time according to the distance between the distance sensing part 130; wherein the greater the distance between the proximity switch 150 and the distance sensing piece 133, the greater the current value displayed, in the case that the current value exceeds the preset current value, it is determined that the diameter of the steel wire rope is excessively worn.

[0048] It can be understood that the steel wire rope diameter detection device 100 provided by the embodiment of the present disclosure is provided with a connecting piece 110, a moving part 120, a distance sensing part 130, a reset piece 140 and a proximity switch 150. Wherein, the connecting piece 110 can be abutted to the steel wire rope to be detected, and when the device where the steel wire rope is located is started, the steel wire rope can slide relative to the connecting piece 110. The moving part 120 is connected to the connecting piece 110, and in the case that the diameter of the rope changes during the movement of the steel wire rope, the pressure of the steel wire rope on the connecting piece 110 changes, so that the connecting piece 110 is displaced, thereby driving the moving part 120 to move. The distance sensing part 130 is connected to the moving part 120 and can sense the distance between the proximity switch 150. The proximity switch 150 can display the current value in real time according to the distance between the distance sensing part. The reset piece 140 is arranged on the moving part 120, and in the case that the diameter of the steel wire rope is in a normal state, the pressure of the steel wire rope on the connecting piece 110 is larger, the connecting piece 110 drives the moving part 120 to move away from the steel wire rope, and at the same time, the reset piece 140 is compressed. In the case that the diameter of the steel wire rope is worn, the pressure of the steel wire rope on the connecting piece 110 decreases, so that the reset piece 140 exerts a resilient force on the connecting piece 110 through the moving part 120, so that the moving part 120 and the connecting piece 110 move to the initial position, and then the distance sensing part 130 moves to the initial position, thereby avoiding the case that the position of the distance sensing part 130 changes without following the change of the diameter of the rope, so that the distance sensing part 130 cannot respond to the change of the diameter of the rope, and the current value displayed by the proximity switch 150 does not change, so as to ensure that the steel wire rope diameter detection device 100 can detect the change of the diameter of the steel wire rope at different positions in real time. In this way, when the diameter of the steel wire rope changes, the current value can be used to determine whether the steel wire rope is worn. After the diameter of the steel wire rope is worn and becomes thin, the distance sensing part 130 moves away from the proximity switch 150 under the action of the reset piece 140, and the greater the distance between the proximity switch 150 and the distance sensing part 133, the greater the current value displayed by the proximity switch 150. In the case that the actual current value exceeds the preset current value, it can be determined that the diameter of the steel wire rope is excessively worn, so that the worker can replace the worn steel wire rope. Through accurate detection of the diameter of the steel wire rope, stable operation of the device is ensured, and safety and reliability are improved.

[0049] It should be noted that the initial distance between the distance sensing part 130 and the proximity switch 150 can be adjusted according to the standard diameter size of the steel wire rope to be detected, so that the proximity switch 150 can display the corresponding current value according to the diameter size of different steel wire ropes, thereby improving the applicability.

[0050] In some examples, as Figure 1 and Figure 2As shown, the connecting member 110 comprises a frame body 111, the frame body 111 is provided with a slot at both sides, and the frame body 111 is connected to the moving part 120; a rotating shaft 112 is rotatably connected to the slot; and a rope wheel 113 is connected to the rotating shaft 112, and the rope wheel 113 is used to rotatably connect the steel wire rope.

[0051] It can be understood that the connecting member 110 can be provided with the frame body 111, the rotating shaft 112 and the rope wheel 113. Among them, the frame body 111 is provided with a slot at the corresponding position of both sides, and the frame body 111 can be connected to the moving part 120, the rotating shaft 112 can be rotatably inserted into the slot, and the rope wheel 113 is connected to the rotating shaft 112. When the steel wire rope presses on the rope wheel 113, the steel wire rope moves, the rope wheel 113 rotates, the friction between the rope wheel 113 and the steel wire rope is reduced, the normal operation of the steel wire rope is avoided, and the wear of the rope wheel 113 and the steel wire rope is reduced.

[0052] In some examples, as shown in Figure 1 and Figure 2 As shown, the steel wire rope diameter detection device 100 further comprises a housing 160, the frame body 111 is arranged in the housing 160, and part of the rope wheel 113 protrudes from the opening of the housing 160, and the moving part 120 is arranged in the housing 160; a limiting member 170 is arranged in the housing 160, and is used to limit the radial displacement of the rope wheel 113.

[0053] It can be understood that the steel wire rope diameter detection device 100 can also be provided with the housing 160 and the limiting member 170. Among them, the frame body 111 can be arranged in the housing 160, and in the case that the rope wheel 113 is installed on the frame body 111, part of the rope wheel 113 protrudes from the opening of the housing 160, so as to be in contact with the steel wire rope. The moving part 120 is arranged in the bottom of the housing 160, and the frame body 111, the rope wheel 113 and the moving part 120 are protected by the housing 160, thereby improving the reliability. The housing 160 can be provided with the limiting member 170, which limits the radial displacement of the rope wheel 113 when it is in contact with the steel wire rope, so as to improve the stability. Exemplarily, the limiting member 170 can be a buckle, which is used to buckle on the top of the rotating shaft 112 after the rope wheel 113 is installed in place, so as to ensure that the rotating shaft 112 can rotate while limiting the displacement of the rotating shaft 112 along the radial direction, thereby limiting the radial displacement of the rope wheel 113.

[0054] In some examples, as shown in Figure 1 and Figure 2As shown in the figure, the moving part 120 comprises a first connecting rod 121, one end of the first connecting rod 121 is connected to the frame body 111; a sleeve 122 is sleeved on the first connecting rod 121, the reset member 140 is arranged in the sleeve 122, and the other end of the first connecting rod 121 is used to press on the reset member 140.

[0055] It can be understood that the moving part 120 can be provided with the first connecting rod 121 and the sleeve 122. Wherein, one end of the first connecting rod 121 is connected to the frame body 111, the sleeve 122 is sleeved on the first connecting rod 121, and the reset member 140 is arranged in the sleeve 122, and the other end of the first connecting rod 121 can press on the reset member 140. In this way, when the rope diameter of the steel wire rope is within the normal range, after the steel wire rope exerts pressure on the rope wheel 113, the rope wheel 113 drives the frame body 111 to move downward, the frame body 111 drives the first connecting rod 121 to move downward relative to the sleeve 122, and the reset member 140 is compressed. After the steel wire rope is worn, the rope diameter decreases, the pressure of the steel wire rope on the rope wheel 113 decreases, the reset member 140 rebounds, and drives the first connecting rod 121 to move upward relative to the sleeve 122.

[0056] In some examples, as shown in Figure 1 and Figure 2 The moving part 120 further comprises an adjusting member, the reset member 140 comprises a reset spring, and the adjusting member is used to adjust the pre-tightening force of the reset spring.

[0057] It can be understood that the moving part 120 can also be provided with an adjusting member. Specifically, the reset member 140 can be a reset spring, and the pre-tightening force of the reset spring can be adjusted by the adjusting member, so as to adjust the pre-tightening force according to the steel wire rope with different rope diameters, ensure the sensitivity of the reset member 140 to the change of the rope diameter of the steel wire rope, and thus make the proximity switch 150 display accurate current value and improve detection accuracy.

[0058] In some examples, as shown in Figure 1 and Figure 2 The adjusting part comprises an adjusting bolt 123, one end of the sleeve 122 away from the frame body 111 is provided with an internal thread, the adjusting bolt 123 is screwed in the internal thread, and the adjusting bolt 123 presses on the reset spring.

[0059] It can be understood that the adjusting part can be an adjusting bolt 123. Specifically, one end of the sleeve 122 away from the frame body 111 can be provided with an internal thread, the adjusting bolt 123 can be screwed in the internal thread, and by screwing the adjusting bolt 123 in different positions, the adjusting screw can press the reset spring to different sizes, so as to correspond to the steel wire rope with different rope diameters.

[0061] It can be understood that the distance sensing part 130 can be provided with the second connecting rod 131, the third connecting rod 132 and the distance sensing piece 133. Among them, the first long hole is arranged at the symmetrical position of the axial direction of the sleeve 122, and the second long hole is arranged at the symmetrical position of the axial direction of the first connecting rod 121. The second long hole corresponds to the position of the first long hole. The second connecting rod 131 can be arranged in the first long hole and the second long hole along the radial direction of the first connecting rod 121, so that the second connecting rod 131 can move along the axial direction of the first connecting rod 121 in the first long hole and the second long hole. One end of the third connecting rod 132 is connected to the second connecting rod 131 along the axial direction of the first connecting rod 121, and the distance sensing piece 133 is arranged at the other end of the third connecting rod 132. In this way, when the first connecting rod 121 moves along the axial direction, it drives the second connecting rod 131 and the third connecting rod 132 to move along the axial direction of the first connecting rod 121, thereby changing the distance between the distance sensing piece 133 and the proximity switch 150, so that the current value displayed by the proximity switch 150 changes.

[0062] In some examples, as shown in Figure 1 and Figure 2 The second connecting rod 131 is a threaded rod, and the third connecting rod 132 is connected to the threaded rod through a fastening nut.

[0063] It can be understood that the second connecting rod 131 can be a threaded rod, a connecting head can be arranged at one end of the third connecting rod 132, the connecting head is provided with a through hole, the threaded rod is inserted into the connecting head through the through hole, and two fastening nuts can be screwed on the threaded rod and located at both ends of the connecting head respectively, so as to fix the third connecting rod 132 to the second connecting rod 131, improve the stability, and facilitate installation and disassembly.

Specifically, a threaded hole can be formed in the radial direction of the screw rod, and a hole body can be formed in the radial direction of the sleeve 122, the position of the hole body corresponds to the position of the threaded hole, so that the limiting screw rod can pass through the hole body and be screwed in the threaded hole, and when the limiting screw rod is installed in place, there is a gap between the limiting screw rod and the side wall of the sleeve 122, so as to limit the screw rod and prevent it from rotating while ensuring that the screw rod can move along the axis direction of the first connecting rod 121, thereby improving the reliability.

[0066] In some examples, the steel wire rope diameter detection device 100 further comprises a controller connected to the driving mechanism of the steel wire rope, and an alarm electrically connected to the controller. The controller is configured to determine the diameter state of the steel wire rope according to the current value sent by the proximity switch 150. When the current value is between 16 mA and 18 mA, the controller controls the alarm to issue an alarm. When the current value is greater than or equal to 18.5 mA, the controller controls the driving mechanism to be powered off.

The controller can be electrically connected to the driving mechanism of the steel wire rope, and the controller can be electrically connected to the alarm. The controller can determine the diameter state of the steel wire rope according to the current value sent by the proximity switch 150. When the current value is between 13.5 mA and 16 mA, the controller determines that the diameter is within a normal range. When the current value is between 16 mA and 18 mA, the controller controls the alarm to issue an audible and visual alarm to prompt the staff that the diameter of the steel wire rope is reduced, the steel wire rope is worn or the diameter is reduced by 7% to 10%, and the reason for the diameter reduction of the steel wire rope needs to be checked in time. When the current value is greater than or equal to 18.5 mA, it indicates that the steel wire rope is worn or the diameter is reduced by more than 10%, and the controller controls the driving mechanism to be powered off, so as to avoid the rupture of the steel wire rope due to its excessive thinness, resulting in safety accidents and equipment damage, thereby improving the safety.
