Description

Technical Field

[0001] The utility model relates to the technical field of steel wire rope detection, in particular to a device for detecting broken strands and wires in elevator steel wire ropes. Background Art

[0002] Elevator wire ropes are typically round and consist primarily of strands of steel wire and a core. If a wire breaks, the tension in the rope changes. If the elevator continues to operate, the rope may become twisted at the break, causing it to vibrate as it passes over the traction sheave. To ensure safe elevator operation, a strand break detection device is installed on the rope to detect broken strands.

[0003] In order to solve the problem of inconvenient positioning of traditional clip installation, the current elevator wire rope broken strand detection device will adopt an elevator traction wire rope broken strand detection device disclosed in Publication No. CN219116907U. By providing a first positioning block, a second positioning block, a lifting handle and a positioning assembly, the first positioning block and the second positioning block are well positioned, thus solving the problem of poor positioning in the existing device.

[0004] When the above technical solution is actually implemented, multiple steel ropes are usually used to improve the stability of the elevator. However, the device that can only detect one steel rope at a time is inefficient and can only detect the steel ropes one by one each time it is used. Summary of the Invention

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a device for detecting broken strands and wires in an elevator wire rope, comprising a detection chamber, wherein a movable placement ring is installed inside the detection chamber, and the placement rings are evenly distributed along the interior of the detection chamber, a support rod penetrating the inner wall of the detection chamber is provided on a side of the placement ring close to the inner wall of the detection chamber, and a limit plate is fixedly provided at the end of the support rod, and a propulsion assembly is provided between the placement ring and the detection chamber;

[0007] An elastic member is provided between the two groups of placement rings, and a telescopic rod is passed through the interior of the elastic member. A weak magnetic field sensor is fixedly provided inside the placement ring.

[0008] Preferably, guide components are provided on both the upper and lower sides of the weak magnetic field sensor, and the guide components are fixed to the inner wall of the placement ring.

[0009] Preferably, the guide assembly includes a sleeve perpendicular to the placement ring, an inner rod is passed through the interior of the sleeve, and a limiting piece is fixed to the end of the inner rod.

[0010] Preferably, the diameter of the limiting member is larger than the outer diameter of the sleeve, a support spring is sleeved on the surface of the sleeve, one end of the support spring is fixed on the placement ring, and the other end of the support spring is fixed on the limiting member.

[0011] Preferably, a guide ball is rotatably mounted inside the limiting member, and the limiting member and the guide ball form a semi-enclosed structure, and the guide components are evenly distributed at equal distances along the surface of the placement ring.

[0012] Preferably, the propulsion assembly includes a propulsion plate, and a propulsion screw penetrating the inner wall of the detection chamber is provided on one side of the propulsion plate close to the inner wall of the detection chamber, and the propulsion screw is threadedly connected to the detection chamber.

[0013] Preferably, a knob is fixedly provided at the end of the advancement screw, and the advancement screw is installed in the middle of the advancement plate through a bearing.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Multiple sets of steel wire ropes can be passed through the multiple sets of placement rings. As the propulsion assembly pushes the placement rings inward, the elastic parts and telescopic rods between the placement rings are squeezed against each other, thus achieving simultaneous detection of multiple sets of steel wire ropes.

[0016] 2. Through the guide assembly provided, the guide ball rotates in the limiter when the wire rope moves, thereby guiding the wire rope. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The utility model provides a technical solution:

[0026] See also Figures 1 to 4 A device for detecting broken strands and wires in an elevator wire rope comprises a detection chamber 1, wherein movable placement rings 2 are installed inside the detection chamber 1, and the placement rings 2 are evenly distributed along the interior of the detection chamber 1. A support rod 3 is provided on the side of the placement ring 2 close to the inner wall of the detection chamber 1, and a limit plate 4 is fixedly provided at the end of the support rod 3. A propulsion assembly 5 is provided between the placement ring 2 and the detection chamber 1.

[0027] An elastic member 6 is provided between the two groups of placement rings 2 , and a telescopic rod 7 is passed through the interior of the elastic member 6 . A weak magnetic field sensor 9 is fixedly provided inside the placement rings 2 .

[0028] By adopting the above technical solution, the steel wire rope passes through the two groups of placement rings 2. The multiple groups of placement rings 2 set up can pass through multiple groups of steel wire ropes. With the propulsion of the propulsion component 5, the placement rings 2 can be pushed inward, so that the elastic parts 6 and the telescopic rods 7 between the placement rings 2 are squeezed against each other. Before the steel wire rope is detected, it is first processed by a permanent magnet. When the steel wire rope passes through the weak magnetic field sensor 9, the magnetic field process of the steel wire rope is detected, thereby realizing the simultaneous detection of multiple groups of steel wire ropes.

[0029] Specifically, such as Figure 4As shown, guide assemblies 8 are provided on the upper and lower sides of the weak magnetic field sensor 9, and the guide assembly 8 is fixed on the inner wall of the placement ring 2. The guide assembly 8 includes a sleeve 801 perpendicular to the placement ring 2, and an inner rod 805 is passed through the interior of the sleeve 801, and a limiting member 803 is fixed to the end of the inner rod 805. The diameter of the limiting member 803 is larger than the outer diameter of the sleeve 801, and a support spring 802 is provided on the surface of the sleeve 801, and one end of the support spring 802 is fixed on the placement ring 2, and the other end of the support spring 802 is fixed on the limiting member 803. A guide ball 804 is rotatably installed inside the limiting member 803, and the limiting member 803 and the guide ball 804 form a semi-enclosed structure, and the guide assemblies 8 are evenly distributed along the surface of the placement ring 2.

[0030] By adopting the above technical solution, when the wire rope passes through the placement ring 2, it can reversely squeeze the support spring 802, and the inner rod 805 retracts at the same time in the sleeve 801. At this time, the guide ball 804 and the wire rope are in contact with each other. When the wire rope moves, the guide ball 804 can rotate in the limit member 803, thereby guiding the wire rope.

[0031] Specifically, such as Figure 2 As shown, the propulsion assembly 5 includes a propulsion plate 503, and a propulsion screw 502 that penetrates the inner wall of the detection chamber 1 is provided on the side of the propulsion plate 503 close to the inner wall of the detection chamber 1. The propulsion screw 502 is threadedly connected to the detection chamber 1, and a knob 501 is fixedly provided at the end of the propulsion screw 502. The propulsion screw 502 is installed in the middle of the propulsion plate 503 through a bearing.

[0032] By adopting the above technical solution, the knob 501 is rotated, and the knob 501 drives the advancement screw 502 to rotate, thereby pushing the advancement plate 503 to move toward the side close to the placement ring 2. At this time, the distance between the two groups of placement rings 2 is shortened.

[0033] Working principle: the steel wire rope passes through the two groups of placement rings 2. The multiple groups of placement rings 2 set can pass through multiple groups of steel wire ropes. After the knob 501 drives the advancement screw 502 to rotate, the advancement plate 503 can be pushed to move to the side close to the placement ring 2. At this time, the distance between the two groups of placement rings 2 is shortened, and the placement ring 2 can be pushed inward, so that the elastic member 6 and the telescopic rod 7 between the placement rings 2 are squeezed against each other, and the support spring 802 is squeezed in the opposite direction. The inner rod 805 retracts simultaneously in the sleeve 801. At this time, the guide ball 804 and the steel wire rope are in contact with each other. When the steel wire rope moves, the guide ball 804 can be rotated in the limit member 803, thereby guiding the steel wire rope. Before the steel wire rope is detected, it is first processed by a permanent magnet. When the steel wire rope passes through the weak magnetic field sensor 9, the magnetic field process of the steel wire rope is detected, thereby realizing simultaneous detection of multiple groups of steel wire ropes.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
