Steel wire rope slippage detection equipment

Abstract

The utility model relates to steel wire rope slippage detection equipment. Displacement errors are determined through slippage of a counterweight frame. In the actual operation process of an elevator, two working conditions may occur, one working condition is that a lower beam assembly makes contact with the bottom of an elevator shaft, a steel wire rope can unload force and relax, the measured displacement result of the steel wire rope is inaccurate, and whether the elevator needs to be overhauled or not can be determined by judging whether the pressure peak value fed back by a pressure sensor reaches a set threshold value or not. And the other working condition is that the counterweight frame runs in the air, the steel wire rope is tightened, and the displacement of the steel wire rope can be detected by using the slippage measurer. Actually, the steel wire rope slippage detection equipment takes the counterweight mechanism as a main body, and the probability of inaccurate displacement result of the steel wire rope can be reduced by utilizing the gravity of the counterweight block and the rigidity of the steel wire rope. Due to the fact that the rigidity of the steel wire rope is large, the unloading force transmission of the steel wire rope at the balancing weight end is affected by the gravity of the balancing weight to be kept in a suspended state and a tightened state, and the measuring precision is high.

Description

Technical Field

[0001] The present application relates to the technical field of elevator equipment, and in particular to a wire rope slippage detection device. Background Art

[0002] In the operation of traditional elevator equipment, the counterweight mechanism is a device that assists the elevator car in its reciprocating motion. In the operation of the elevator equipment, due to the quality of the automation control program and the delay in the coordination of the mechanical and electrical equipment, a certain amount of displacement error will occur in the elevator car. If the displacement error exceeds the design index or safety range, the elevator needs to be repaired. The traditional method for measuring the displacement error of elevator equipment often uses the displacement error of the car. This scheme ignores the deformation of the elevator wire rope in the mechanical equipment under heavy load conditions, and is prone to large system errors during the measurement process, which in turn causes the disadvantage of inaccurate measurement. For this reason, it is necessary to propose a wire rope slip detection device to address the disadvantage of inaccurate measurement caused by the traditional scheme for measuring displacement errors.

[0070] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0071] The present application provides a wire rope slippage detection device.

[0072] like Figure 1 As shown, in one embodiment of the present application, a wire rope slippage detection device is arranged in an elevator device, and the elevator equipment includes a wire rope and a signal cable. The wire rope slippage detection device includes a counterweight frame 100, a counterweight block 200, a counterweight wheel 300, a buffer 400, a pressure sensor 500 and a slippage measurer 600.

[0073] The counterweight frame 100 includes an upper beam assembly 110, a straight beam assembly 120 and a lower beam assembly 130. The straight beam assembly 120 is disposed between the upper beam assembly 110 and the lower beam assembly 130. The straight beam assembly 120 is fixedly connected to the upper beam assembly 110, and the straight beam assembly 120 is fixedly connected to the lower beam assembly 130.

[0074] A plurality of counterweight blocks 200 are disposed between the upper beam assembly 110 and the lower beam assembly 130 , and each counterweight block 200 is fixedly connected to the straight beam assembly 120 .

[0075] Each counterweight wheel 300 is rotatably connected to the upper beam assembly 110 , and a steel wire rope is wound between the two counterweight wheels 300 .

[0076] The buffer 400 is fixedly connected to the lower beam assembly 130 .

[0077] The pressure sensor 500 is disposed between the buffer 400 and the lower beam assembly 130 , and the pressure sensor 500 is communicatively connected with a signal cable.

[0078] The slip measurement device 600 is arranged close to the steel wire rope, the slip measurement device 600 is fixedly connected to the upper beam assembly 110, and the slip measurement device 600 is electrically connected to the signal cable. Specifically, the counterweight frame 100 carries the counterweight block 200, which provides a counterweight for the steel wire rope to prevent deformation, thereby improving the measurement accuracy.

[0079] When the wire rope is in a sliding state, the detection end of the slip measurement device moves toward the direction close to the wire rope until the wire rope and the slip measurement device contact each other, so that the slip measurement device detects the slip of the wire rope.

[0080] When the wire rope is in a stationary state, the detection end of the slip measurement device moves in a direction away from the wire rope until the wire rope and the slip measurement device lose contact and turn into a separated state.

[0081] More specifically, when the lower beam assembly 130 contacts the bottom of the elevator shaft, the displacement error of the counterweight frame 100 is too large, and the counterweight frame 100 will have a large overshoot. This overshoot is expressed on the pressure sensor 500 as a pressure peak exceeding a set threshold.

[0082] The present application relates to a wire rope slippage detection device, which determines the displacement error by the slippage of the counterweight frame 100. In fact, during the actual operation of the elevator, two working conditions may occur. One working condition is that the lower beam assembly 130 contacts the bottom of the elevator shaft. In this working condition, the wire rope will unload and relax, and the displacement result of the wire rope will be inaccurate. It can be determined whether the elevator needs maintenance by using the pressure peak feedback from the pressure sensor 500 to determine whether it reaches the set threshold. The other working condition is that the counterweight frame 100 is running in the air. In this working condition, the wire rope is taut, and the displacement of the wire rope can be detected by the slippage meter 600. In fact, the wire rope slippage detection device is based on the counterweight mechanism, and the gravity of the counterweight block 200 and the stiffness of the wire rope can be used to reduce the probability of inaccurate displacement results of the wire rope. Since the rigidity of the steel wire rope is relatively large, at the end of the counterweight block 200, the unloading force transmission of the steel wire rope is affected by the gravity of the counterweight block 200 and will remain in a suspended and taut state. Under this working condition, the measurement accuracy is relatively high.

[0083] like Figure 2 As shown, in one embodiment of the present application, the buffer 400 includes a first layer plate 410, a second layer plate 420 and a recoil spring 430. The pressure sensor 500 is disposed between the first layer plate 410 and the lower beam assembly 130. The pressure sensor 500 is fixedly connected to the first layer plate 410. The pressure sensor 500 is also fixedly connected to the lower beam assembly 130. The recoil spring 430 is disposed between the first layer plate 410 and the second layer plate 420.

[0084] Specifically, the buffer 400 includes a first plate 410 , a second plate 420 and a recoil spring 430 . One of the functions of the recoil spring 430 is to buffer the gravity impulse of the counterweight frame 100 and reduce the peak pressure of the pressure sensor 500 .

[0085] The second function of the recoil spring 430 is to keep the movement and stopping process of the counterweight frame 100 stable.

[0086] like Figure 2 As shown, in one embodiment of the present application, the buffer 400 further includes a first set of rods 440 and a second set of rods 450. The first set of rods 440 is sleeved on the outside of the second set of rods 450. The recoil spring 430 is sleeved on the outside of the first set of rods 440. The first set of rods 440 is fixedly connected to the first layer plate 410. The second set of rods 450 is fixedly connected to the second layer plate 420.

[0087] Specifically, the first set of rods 440 and the second set of rods 450 are used to guide the recoil spring 430 to reciprocately compress and relax in a direction perpendicular to the extension line of the plumb line.

[0088] The first rod 440 is sleeved on the outer circumference of the second rod 450. This ensures that the first rod 440 and the second rod 450 can provide a collapse space during the process of the return spring 430 being compressed and relaxed in a direction perpendicular to the extension line of the plumb line.

[0089] like Figure 2 As shown, in one embodiment of the present application, the central axis of the first sleeve rod 440 coincides with the central axis of the second sleeve rod 450. The central axis of the first sleeve rod 440 coincides with the central axis of the recoil spring 430. The central axis of the recoil spring 430 is perpendicular to the first layer plate 410. The central axis of the recoil spring 430 is perpendicular to the second layer plate 420.

[0090] This embodiment relates to a buffer 400. The first set of rods 440 and the second set of rods 450 are used to guide the recoil spring 430 to reciprocate and compress and relax in a direction perpendicular to the extension line of the plumb line. The recoil spring 430 buffers the gravity impulse of the counterweight frame 100 and reduces the peak pressure of the pressure sensor 500. The damage rate of the pressure sensor 500 is reduced.

[0091] like Figure 3 As shown, in one embodiment of the present application, the slip measurement device 600 includes a fixed frame 610. The fixed frame 610 includes a horizontal rod 611 and a vertical rod 612. The horizontal rod 611 is fixedly connected to the upper beam assembly 110. The horizontal rod 611 is fixedly connected to the vertical rod 612. The horizontal rod 611 and the vertical rod 612 are perpendicular to each other.

[0092] Specifically, the fixing frame 610 is a bracket of the slip measuring device 600. The horizontal rod 611 is used to fix the upper beam assembly 110 to ensure that the entire slip measuring device 600 has a force-bearing point. The vertical rod 612 is used to support the overall measuring mechanism of the slip measuring device 600.

[0093] like Figure 3 As shown, in one embodiment of the present application, the slip measurement device 600 further includes a resistance wheel 620, a swing rod 640 and a torsion spring 650. The resistance wheel 620 serves as a detection end of the slip measurement device 600. The first end 641 of the swing rod 640 is rotatably connected to the vertical rod 612. The second end 642 of the swing rod 640 is rotatably connected to the resistance wheel 620. The first end 651 of the torsion spring 650 is fixedly connected to the second end 642 of the swing rod 640. The second end 652 of the torsion spring 650 is fixedly connected to the inner circumference of the resistance wheel 620.

[0094] Specifically, the rotation connection between the resistance wheel 620 and the swing rod 640 ensures that the resistance wheel 620 can rotate around its own axial center axis when it contacts the moving wire rope. The swing rod 640 is rotationally connected to the vertical rod 612. The resistance wheel 620 can be pressed against the wire rope, or the resistance wheel 620 can be separated from the wire rope. The torsion spring 650 is connected to the resistance wheel 620, so that the resistance wheel 620 can return to the initial state after being rotated by force.

[0095] When the wire rope is in a sliding state, the swing rod drives the resistance wheel to move towards the wire rope until the wire rope and the resistance wheel contact each other, so that the resistance wheel can detect the slippage of the wire rope.

[0096] like Figure 3 As shown, in one embodiment of the present application, the slippage measuring device 600 further includes a sliding rod mechanism 630. The sliding rod mechanism 630 includes a motor 631, a gear 632 and a sliding gear rod 633. The motor 631 is fixedly connected to the horizontal rod 611. The gear 632 is fixedly connected to the power shaft of the motor 631. The gear 632 is meshed with the sliding gear rod 633.

[0097] Specifically, the motor 631 is fixedly connected to the horizontal rod 611 via a connecting rod 636 .

[0098] The sliding gear rod 633 is provided with a tooth 634. The tooth 634 is fixedly connected to the sliding gear rod 633. The tooth 634 is meshed with the gear 632. The sliding gear rod 633 is provided with an elongated hole 635. The sliding gear rod 633 is slidably connected to the vertical rod 612 through the elongated hole 635. The sliding gear rod 633 abuts against the middle of the swing rod 640.

[0099] Specifically, when the elevator car stops running, the motor 631 rotates, the motor 631 drives the gear 632 to rotate, the gear 632 engages the sliding gear rod 633, and the sliding gear rod 633 slides in parallel. The sliding gear rod 633 abuts against the middle of the swing rod 640. When the sliding gear rod 633 slides in parallel, the swing rod 640 rotates, and the swing rod 640 drives the resistance wheel 620 to abut against the wire rope.

[0100] When the wire rope is in a stationary state, the swing rod drives the resistance wheel to swing away from the wire rope until the wire rope is out of contact with the resistance wheel and turns into a separated state, thereby making the middle part of the swing rod abut against the edge of the sliding gear rod.

[0101] like Figure 4As shown, in one embodiment of the present application, the resistor wheel 620 is provided with an annular groove 621. The annular groove 621 is provided on the outer edge surface of the resistor wheel 620. A resistor sheet 622 is provided in a preset portion of the annular groove 621. The outer edge surface of the resistor wheel 620 has a rough surface, and the outer edge surface of the resistor wheel 620 is coated with an insulating layer.

[0102] The slip measurement device 600 further includes a first electrode 660 and a second electrode 670. The first electrode 660 and the second electrode 670 are both electrically connected to the signal cable. The first electrode 660 and the second electrode 670 are disposed close to the resistor sheet 622, and the first electrode 660 and the second electrode 670 are both attached to the groove surface of the annular groove 621.

[0103] Specifically, when the resistance wheel 620 is against the moving wire rope, it will rotate. When the outer edge rotation amount of the resistance wheel 620 exceeds the design value, the first electrode 660 and the second electrode 670 can contact the resistor sheet 622 of the preset groove surface. At this time, the first electrode 660 and the second electrode 670 are connected, and the first electrode 660 and the second electrode 670 feedback the prompt level, prompting the maintenance personnel to inspect the elevator.

[0104] The technical features of the above-described embodiments can be combined arbitrarily, and the execution order of each method step is not limited. In order to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. The above-described embodiments only express several implementation methods of the present application, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the patent of this application. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present application, several deformations and improvements can be made, which all belong to the scope of protection of the present application. Therefore, the scope of protection of the present application shall be based on the attached claims.
