Description

Technical Field

[0001] This invention relates to the field of elevator technology, specifically to a wire rope broken wire detection device and its installation method. Background Technology

[0002] In the prior art, the structure of a traction elevator system is as follows: Figure 1 As shown, the traction elevator system includes a car 1 and a corresponding counterweight 2. The car 1 and counterweight 2 are connected by a steel wire rope 4. The traction sheave 6 of the traction machine 3 drives the steel wire rope 4 to move, completing the rising and falling movements of the car 1. The guide wheel 7 is used to adjust the distance between the car 1 and the counterweight 2. When the broken wire detection device 5 detects broken wires in the steel wire rope 4, it needs to be placed in a position such as... Figure 1 The multiple steel wire ropes to be tested are located near the traction machine 3 shown.

[0003] Due to space constraints, the positions of the wire rope at the car roof and the wire rope at the traction sheave are as follows: Figure 2 The deviation shown indicates that as the elevator travels from the bottom floor to the top floor, the wire rope at the broken wire detection device gradually tends towards the alignment of the wire rope at the top of the car, meaning the wire rope experiences lateral and longitudinal movement. This phenomenon can cause problems such as the sensor inside the broken wire detection device failing to align with the wire rope. Figure 3 As shown.

[0004] To avoid the aforementioned problems, current technologies for detecting broken wires in steel wire ropes generally employ the following solutions: moving the elevator to the second-to-last floor to prevent the steel wire rope from contacting the detection device, or fixing the detection device near the steel wire rope to be tested and installing pulleys below the detection device to press the steel wire rope into place, thus maintaining its original position. However, these two methods only prevent the steel wire rope from wearing down the detection device; they cannot ensure that the sensors inside the detection device are aligned with the steel wire rope during operation. Summary of the Invention

[0009] The detection element assembly includes a detection element, a slide groove, and a slider; the slide groove is fixed inside the sensor body, the slider can slide along the slide groove in the traction wheel axis direction, the detection element is fixedly connected to the slider, and the rolling pulley is fixedly connected to the slider through a connecting rod.

[0010] The lateral displacement component includes an inclined guide rail, two sets of composite sliders, and two sets of lateral guide rails; the two sets of lateral guide rails are fixedly connected to the frame, and their directions are parallel to the axis of the traction wheel; the composite slider includes a moving slider and a steering slider, the moving slider is slidably connected to the lateral guide rail, the moving slider is rotatably connected to the steering slider, and the steering slider is slidably connected to the inclined guide rail.

Those skilled in the art can fully understand other advantages and technical effects of the present invention from the content disclosed in this specification.

[0026] Example 1

[0027] like Figure 4 As shown, this embodiment provides a wire rope broken wire detection device 5, including a frame 51, a sensor assembly 52 and multiple sets of lateral movement assemblies 53;

[0028] like Figure 5As shown, the frame 51 is preferably fixed near the traction machine, such as on the traction machine base or a load-bearing beam. The sensor assembly 52 includes a contact pulley 521, a sensor body 522, multiple sets of detection element assemblies 523, a guide rail assembly 524, a connecting rod 525, and a rolling pulley 526. The guide rail assembly 524 includes a guide rail 5241 and a guide block 5242. The guide rail 5241 is fixedly connected to the frame 51, and the placement direction of the guide rail 5241 is perpendicular to the axis of the traction wheel. The guide block 5242 is slidably connected to the guide rail 5241 and fixedly connected to the sensor body 522. The contact pulley 521 is fixedly connected to the sensor body 522. The set of detection element assembly 523 includes a detection element 5231, a slide groove 5232, and a slider 5233. The slide groove 5232 is fixed inside the sensor body 522. The slider 5233 can slide along the slide groove 5232 in the traction wheel axis direction. The detection element 5231 is fixedly connected to the slider 5233. The rolling pulley 526 is fixedly connected to the slider 5233 through a connecting rod 525.

[0029] The slide 5232 also includes a limiting element that restricts the range of movement of the slider 5233 within the slide 5232. The sensor assembly 52 also has an elastic element that presses the contact pulley 521 against the surface of the wire rope 4.

[0030] like Figure 6 The aforementioned set of lateral displacement components 53 includes an inclined guide rail 531, two sets of composite sliders 532, and two sets of lateral guide rails 533. The two sets of lateral guide rails 533 are fixedly connected to the frame 51, and their directions are parallel to the axis of the traction wheel 6. The set of composite sliders 532 includes a movable slider 5321 and a steering slider 5322. The movable slider 5321 is slidably connected to the lateral guide rails 533, and the movable slider 5321 is rotatably connected to the steering slider 5322. The steering slider 5322 is slidably connected to the inclined guide rail 531. When the movable slider 5321 slides on the guide rail 531, the inclined guide rail 531 can change its position on the frame 51 through the steering slider 5322.

[0031] This embodiment also provides an installation method for a wire rope broken wire detection device, including the following steps:

[0032] Step S1: Before the elevator system starts running, adjust the slider 5233 so that the detection element 5231 is aligned with the wire rope, and move the moving slider 5321 of the composite slider 532 to the position of the transverse guide rail 533, change the orientation of the inclined guide rail 531 until it contacts the rolling pulley 526 fixedly connected to the slider 5233, and lock the sliding of the moving slider 5321 and the steering slider 5322 in a set of composite sliders 532.

[0033] Step S2: After the elevator system finishes operating, readjust slider 5233 to align detection element 5231 with the wire rope, and move slider 5321 of another set of composite sliders 532 until the inclined guide rail 531 contacts the rolling pulley 526 again. Then lock composite slider 532 to fix the position of inclined guide rail 531 on frame 51.

[0034] Figure 7 , Figure 8 The diagram illustrates the motion principle of the wire rope breakage detection device 5. After the inclined guide rail is positioned by the lateral displacement component, when the position of the wire rope 4 changes, it pushes the contact pulley 521, causing the sensor assembly 52 to move radially along the traction sheave. The detection element 5231 inside the sensor assembly 52 moves axially along the traction sheave along the wire rope 4 via the inclined guide rail 531 and the slide groove 5232, ensuring that the detection element can be aligned with the wire rope 4.

[0035] The present invention has been described in detail above through specific embodiments and examples, but these are not intended to limit the invention. Many modifications and improvements can be made by those skilled in the art without departing from the principles of the invention, and these should also be considered within the scope of protection of the present invention.
