Description

Technical Field

[0001] The present invention relates to the technical field of wear detection, and particularly relates to a wear detection device for elevator traction steel ropes. Background Art

[0002] The elevator traction steel rope is an important component in the elevator system, which is used to connect the traction wheel at the bottom of the elevator and the driving mechanism of the elevator, playing the role of transmitting power and supporting the operation of the elevator. It is usually composed of multiple strands of steel ropes, with the characteristics of high strength, wear resistance and corrosion resistance, and can bear the weight of the elevator and the tensile force generated during the operation process; during the continuous working process of the steel rope, due to wear and stretching, the external shape of the steel rope will change, such as the diameter becoming smaller. In order to ensure the safety of the elevator operation, it is necessary to detect the wear of the steel rope to facilitate the timely replacement of the worn steel rope.

[0003] For example, a wear detection device for elevator traction steel ropes disclosed in the patent with the publication number of CN115959542A, since it does not have the function of marking the worn part of the steel rope after detecting the steel rope, in order to ensure the accuracy of the detection, it leads to the subsequent staff still needing to carefully detect the steel rope again.

[0044] Please refer to the attached Figure 3 - attached Figure 8 , in a preferred embodiment, the cleaning mechanism includes: a first shaft rod, which is rotatably installed at the bottom of the connecting plate 34.

[0045] Preferably, the rotation of the third spring rod drives the brush disc 30 to rotate, so as to clean the vicinity of the components where the wire rope is worn, avoiding the situation that the external part of the wire rope has oil stains, which makes it difficult for the paint to adhere.

[0046] Please refer to the attached Figure 1 - attached Figure 7 In a preferred embodiment, the marking mechanism includes: an air cylinder 36, which is vertically and fixedly installed at the bottom of the connecting plate 34.

The telescopic end of the telescopic rod is fixedly installed at the inner top of the air cylinder 36.

A second one-way valve 41 and a first one-way valve 39 are respectively installed on the air outlet pipe 40 and the air inlet pipe 38;

[0047] Furthermore, when the push plate 32 moves downward, the paint inside the marking box 31 is sprayed from the spray head 50 onto the wire rope. By repeating this process in sequence, the marking of this position can be continuously repeated, avoiding the situation of unclear marking.

[0048] The working principle of the present invention: First, install the two mounting seats 1 at the corresponding positions inside the elevator shaft (installed as shown in the attached Figure 1 figure);

[0049] When the wire rope moves upward, the clamping wheel 6 can limit the wire rope, and the clamping wheel 6 will rotate, ensuring that the wire rope in the detection section of the magnetic induction distance measuring instrument 8 does not shake, which helps to improve the accuracy of detection. When the magnetic induction distance measuring instrument 8 detects that a certain wire rope has a diameter change (when it is worn), the controller 2, as the total control end of this detection device and also the data access port of this device, can be specifically connected by wireless connection on the controller 2, or can also be connected by wired means, that is, the controller 2 is provided with corresponding wireless connectors and wired connectors. Then, the corresponding controller 2 will control the electromagnetic ring 14 to be energized according to the detection result of the magnetic induction distance measuring instrument 8, and the controller 2 will control the external alarm to issue an alarm to prompt the staff to handle it in time;

[0050] When the electromagnetic ring 14 is energized, it will generate a suction force on the spline sleeve 15 and cause the spline sleeve 15 to move. At this time, the first spring rod 17 generates a pulling force, so that the spline sleeve 15 can also be spline-connected with the first rotating shaft 12. Since the wire rope moves upward, it will drive the clamping wheel 6 to rotate in the reverse direction. The rotation of the clamping wheel 6 drives the first belt 10 and the first belt pulley 11 to rotate. The rotation of the first belt pulley 11 drives the first rotating shaft 12, the spline sleeve 15 and the second rotating shaft 13 to rotate. The rotation of the second rotating shaft 13 drives the conveyor belt 4 and the round roller 5 to rotate (the torsion shaft generates torsion). The rotation of the conveyor belt 4 drives the strip plate 19 to move upward. The upward movement of the strip plate 19 drives the connecting components thereon (components such as the marking box 31, the brush disc 30 and the fifth gear 48 together with the wire rope) to move upward (at the starting position, the brush disc 30 is not directly below the semi-circular ring 7, so the semi-circular ring 7 will not hinder the upward movement of the brush disc 30). When the fifth gear 48 and the second spring rod 46 move upward, they drive the collar and the sliding column 47 to move upward. Due to the setting of the limiting groove 24, the sliding column 47 will move along the path of the limiting groove 24. At the beginning, the sliding column 47 will move inside the vertical groove corresponding to the limiting groove 24. When the fifth gear 48 contacts the straight rack 23, the fifth gear 48 will rotate forward. The rotation of the fifth gear 48 drives the second spring rod 46, and the rotation of the second spring rod 46 drives the fourth bevel gear 45 and the third bevel gear 44 to rotate. The rotation of the third bevel gear 44 drives the second belt 20 and the second belt pulley 21 to rotate. The rotation of the second belt pulley 21 drives the rotating rod 22 and the connecting plate 34 to rotate. The rotation of the connecting plate 34 drives components such as the brush disc 30, the marking box 31 and the air cylinder 36 to revolve (the revolution of the third spring rod will generate a centrifugal force to make the brush disc 30 move away from the third spring rod to contact the wire rope to be marked). Due to the setting of the tooth ring 26, when the internal gear 49 revolves, it can also rotate. The rotation of the internal gear 49 drives the first bevel gear 28 and the second bevel gear 29 to rotate. The rotation of the second bevel gear 29 drives the third spring rod to rotate. The rotation of the third spring rod drives the brush disc 30 to rotate, so as to clean the vicinity of the components where the wire rope is worn, avoiding the situation that the external part of the wire rope has oil stains, resulting in difficulty in coating adhesion. Due to the setting of the arc-shaped rack 27, when the external gear 35 revolves to approach the wire rope, it can also rotate. The rotation of the external gear 35 drives the reciprocating lead screw 43 to rotate. The rotation of the reciprocating lead screw 43 drives the U-shaped plate 42 to move up and down reciprocally. The up and down movement of the U-shaped plate 42 drives the piston disc 37 to move up and down (the top of the air cylinder 36 is provided with a ventilation hole). When the piston disc 37 moves downward, at this time, the gas inside the air cylinder 36 blows open the second one-way valve 41 on the air outlet pipe 40, so the gas inside the air cylinder 36 will enter the marking box 31 through the air outlet pipe 40. When the piston disc 37 moves upward, the second one-way valve 41 closes and the first one-way valve 39 opens, then the external gas will enter the air cylinder 36 through the air inlet pipe 38. By reciprocating in turn, the marking box 31 can be continuously inflated to realize that the push plate 32 moves downward to spray the coating inside the marking box 31 from the nozzle 50 onto the wire rope.By reciprocating in sequence, the marking of this position can be continuously repeated, avoiding unclear marking. When the sliding column 47 moves from the inside of the vertical groove to the inside of the U-shaped groove, the sliding column 47 will move along the path of the U-shaped groove (when the sliding column 47 enters the upper hypotenuse of the U-shaped groove, the electromagnetic ring 14 is powered off at this time), then the movement of the sliding column 47 drives the telescopic end of the second spring rod 46 to move (move away from the fourth bevel gear 45), so the fifth gear 48 and the straight rack 23 are no longer engaged, and the torque generated by the torsion shaft will cause the conveyor belt 4 to rotate forward. When the sliding column 47 moves to the lower hypotenuse of the U-shaped groove, with the forward rotation of the conveyor belt 4, the sliding column 47 will push open the baffle 25 (which can only open in one direction), so that the sliding column 47 can return to the starting position (the connection of the two limiting grooves 24). And when the torsion shaft makes the conveyor belt 4 rotate forward, since the fifth gear 48 and the straight rack 23 are not engaged, the components on the strip plate 19 will not move. In summary, the marking of a part of the steel wire rope is completed, thereby improving the use effect and efficiency of the equipment;

[0051] When the steel wire rope moves downward, in summary, vice versa, the worn components of the steel wire rope can be marked.
