[0002] In modern society, elevators are widely used and inseparable from people's daily lives. They have become ubiquitous equipment for transporting people and goods in multi-story buildings. The safety performance of elevators plays a vital role. Among them, the elevator car and the counterweight device are connected by wire ropes. The wire ropes are driven by the traction machine to move the elevator car in the shaft. The safety performance of the wire ropes, as the main force-bearing and force-transmitting components, has a great impact on the use of elevators. The elevator wire rope is usually made of multiple strands of steel wires. Its safety problem is mainly broken strands. Once the wire rope is broken, it will not only affect the safety factor of the wire rope, but also increase the number of broken strands if it is not discovered in time, and even the wire rope will break, which will seriously affect the safe operation of the elevator.

[0003] However, in the prior art, when using an elevator steel rope broken strand and broken wire detection device to detect the elevator steel rope broken strands and broken wires, it was found that some elevator steel rope broken strand and broken wire detection devices have a fixed number of elevator steel ropes to be detected, and cannot adjust themselves according to the number of elevator steel ropes to be detected, resulting in low practicality. At the same time, most elevator steel rope broken strand and broken wire detection devices clamp the elevator steel rope inside the detection device through bolt connections, and the installation and disassembly of the bolts are relatively troublesome, which increases the labor intensity of workers.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. The utility model assembles the device at the work site according to the number of elevator steel ropes to be detected, takes out the shells of twice the number of the detected ones, slides the T-shaped fixing block of another shell from one end of the T-shaped fixing groove of the shell, and so on. According to the number of elevator steel ropes to be detected, the shells of twice the number are evenly spliced ​​into two wholes.

[0026] Specifically: the contact pins 105 provided on each housing 1 are connected to the surface of the contact electrode sheet 104 of another corresponding housing 1 to connect the circuit, so that the various contact switches 207 are electrically connected together, which is convenient for electrical connection with the external controller. The external controller controls the elevator controller through the data fed back by each contact switch 207.

[0027] In one embodiment, the detection component 2 includes a pulley 201 and a contact switch 207. A connecting rod 202 is embedded in the interior of the pulley 201 through a bearing. A U-shaped connecting arm 203 is fixedly connected to one side of both ends of the connecting rod 202. A movable rod 204 and a contact rod 205 are fixedly connected to one side of the U-shaped connecting arm 203. The contact rod 205 is located in the inner cavity of the movable rod 204.

When the enlarged rope moves to this device, the connecting rod 202 will be under pressure and move toward the other end of the connecting rod movable groove 101, so that the contact rod 205 and the contact switch 207 generate a contact signal. The external controller detects the contact signal and controls the elevator controller to stop the elevator, thereby detecting the broken strands and wires of the elevator rope; the contact switch 207 is a prior art, and the specific structure will not be repeated here.

When the fixed plug 308 extends into the fixed plug slot 302, when the fixed plug 308 touches the mating end of the mating block moving rod 305, since one end of the fixed plug 308 is chamfered, the mating block moving rod 305 will move under the pressure of the fixed plug 308. At this time, the second spring 306 is deformed until the mating end of the mating block moving rod 305 moves to the inside of the mating slot 309, and the mating block moving rod 305 is moved. The rod 305 is acted upon by the elastic force of the second spring 306, so that the fitting end of the fitting block moving rod 305 is firmly engaged in the fitting groove 309, thereby achieving the purpose of fixation. After the detection is completed, one end of the fitting block moving rod 305 of the shell 1 relative to each other is pulled to make the fitting end of the fitting block moving rod 305 disengage from the fitting groove 309, and the corresponding shell 1 can be taken out. This design avoids the detection device being connected by bolts, and the installation and disassembly by bolts are more troublesome, thereby reducing the labor intensity of workers.

The opening diameter of one end of the movable rod 204 is smaller than the opening diameter of the movable rod 204. The inner cavity of the movable rod 204 provides a movable space for the movement of the limit rod 206. At the same time, the diameter of the limit block is larger than the opening diameter of one end of the movable rod 204, which plays a limiting role.

[0033] In one embodiment, one end of two fixing blocks 301 is fixedly connected to both sides of one end surface of the shell 1, and the two fixing blocks 301 are diagonally distributed, and one end of two fixing blocks 307 is fixedly connected to both sides of one end surface of the shell 1, and the two fixing blocks 307 are diagonally distributed.

This design allows the device to be assembled according to needs, which increases the practicality of the device. The initial state of the second spring 306 is a natural state without force. When the fixed plug 308 extends into the fixed plug slot 302, when the fixed plug 308 touches the mating end of the mating block moving rod 305, due to the chamfer at one end of the fixed plug 308, the mating block moving rod 305 will be moved by the pressure of the fixed plug 308. At this time, the second spring 306 is deformed until the mating The mating end of the block moving rod 305 moves to the inside of the mating groove 309, and the mating block moving rod 305 is acted upon by the elastic force of the spring 2 306, so that the mating end of the mating block moving rod 305 is firmly engaged in the inside of the mating groove 309, thereby achieving the purpose of fixing. The outermost contact electrode sheet 104 and the contact ejector pin 105 of the device are electrically connected to the external controller, and the external controller is electrically connected to the elevator controller. The worker fixes the device with both hands and starts the elevator. The elevator rope moves. When the rope breaks somewhere, the rope diameter at this place will increase, and the increased rope movement When this device is moved, the connecting rod 202 will be pressed to move toward the other end of the connecting rod movable groove 101, so that the contact rod 205 and the contact switch 207 generate a contact signal.
