Description
Technical Field
[0001] The utility model belongs to the technical field of overhead passenger devices, in particular to an anti-flying device for overhead passenger devices. Background Art
[0002] With the rapid development of my country's coal industry, the country attaches great importance to the safety of coal mine technical equipment. Coal mine production safety and safe transportation have become a major concern of governments at all levels and coal mining enterprises. The promotion and application of coal mine overhead passenger devices has greatly reduced the labor intensity of underground coal mine personnel. With the continuous updating and iteration of products, the safety and reliability of transportation have been gradually improved. At present, the use of overhead passenger devices in coal mines and non-coal mines is becoming more and more popular.
[0003] Although the use of overhead passenger devices is becoming more and more popular, users still do not have enough understanding of them, and various protection devices are still not comprehensive enough. Overhead passenger devices may also malfunction during actual use, causing safety accidents. For example, the frequency converter or magnetic starter stops for some reason, the drive wheel or tail wheel on the slope breaks, etc., regardless of the reason, the wire rope may slide down or reverse. If the wire rope cannot be stuck in time, the overhead passenger device may lose control and run away, causing casualties and poor safety protection effect. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the utility model aims to provide an anti-flying device for an overhead passenger device, so as to improve the problem that the wire rope cannot be stuck in time when the overhead passenger device fails.
[0005] The utility model is realized by adopting the following technical solutions:
[0006] A device for preventing a vehicle from flying high in an overhead passenger device comprises a sensor mounting frame and a pair of passenger spacing hangers, the lower ends of the pair of passenger spacing hangers are connected to a supporting wheel hanger, a passenger spacing supporting wheel is rotatably mounted under the pair of supporting wheel hangers, and a steel wire rope is mounted on the upper side of the passenger spacing supporting wheel, an overspeed sensor supporting wheel is rotatably mounted on one side of one supporting wheel hanger through the sensor mounting frame, and the overspeed sensor supporting wheel is mounted on the upper side of the steel wire rope, a speed sensor is mounted on the sensor mounting frame, the other supporting wheel hanger is slidably connected to an anti-flying vehicle holding brake device, and a buffer device is installed between the anti-flying vehicle holding brake device and the other supporting wheel hanger, the speed sensor signal line and the anti-flying vehicle holding brake device power line are commonly connected to a mine-use flameproof and intrinsically safe controller, and the mine-use flameproof and intrinsically safe controller is connected to a comprehensive protection device via a signal line.
[0007] When in use, after the overhead passenger device is started, the wire rope drives the passenger interval supporting wheel on the passenger interval hanger to rotate, and the overspeed sensor supporting wheel also rotates with the movement of the wire rope, and the speed sensor monitors the rotation of the overspeed sensor supporting wheel, thereby realizing the detection of the rotation of the passenger interval supporting wheel. Once the overhead passenger device runs away, the speed sensor will feed back the monitored signal to the mine-used flameproof and intrinsically safe controller. After the mine-used flameproof and intrinsically safe controller analyzes the received signal, it supplies power to the anti-runaway brake device, and the anti-runaway brake device starts to make a braking action. The anti-runaway brake device slowly holds the wire rope. If the fixed rope gripper fixed on the wire rope happens to hit the anti-runaway brake device during the braking action of the anti-runaway brake device, the buffer device connected to the anti-runaway brake device can be used for buffering protection. At the same time, the comprehensive protection device drives the overhead passenger device to stop for protection through a shutdown signal.
[0008] Further preferably, the buffer device includes a spring shock absorber and an I-beam, the spring shock absorber is installed on the I-beam, and the I-beam is installed on another supporting wheel hanger.
[0009] Further preferably, in order to detect whether the overhead passenger device is rotating, two rotation speed sensors are provided, and the two rotation speed sensor probes are arranged at a certain angle relative to the overspeed sensor supporting wheel.
[0010] Further preferably, the outer ends of a pair of passenger spacing wheels are both arranged in an H shape.
[0011] The utility model has the following beneficial effects:
[0012] The utility model realizes that when the wire rope body of the overhead passenger device suddenly reverses, the fixed rope gripper can be clamped in the first time to prevent the wire rope body and the passengers from reversing and ensure the safety of the personnel, through the mutual cooperation of the anti-runaway brake device, the buffer device, the mining flameproof and intrinsically safe controller and the comprehensive protection device, thereby realizing effective braking and locking and stopping when the wire rope of the overhead passenger device slides down and reverses the runaway, further improving the safety and reliability of the overhead passenger device and providing a strong guarantee for safe production.

DETAILED DESCRIPTION

It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two elements. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] The specific embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0023] An anti-flying device for an overhead passenger device comprises a sensor mounting frame 3, a pair of passenger spacing hangers 1, and the lower ends of the pair of passenger spacing hangers 1 are both connected to a supporting wheel hanger 9. Figure 1As shown, the passenger spacing hanger 1 is connected to the roller hanger 9 through a U-bolt 2 with an opening facing downward, so that it is possible to avoid opening a hole on the passenger spacing hanger 1. The U-bolt 1 passes through the roller hanger 9 and is fixed with a nut 7.
[0024] A pair of roller hangers 9 are both rotatably mounted with passenger spacing rollers 6, and a steel wire rope 5 is mounted on the upper side of the passenger spacing rollers 6. The right side of the roller hanger 9 on the left side is rotatably mounted with an overspeed sensor roller 8 through a speed sensor 4 mounting frame, and the overspeed sensor roller 8 is mounted on the upper side of the steel wire rope 5. Two speed sensors 4 are installed on the sensor mounting frame 3, and the two speed sensor probes are set at a certain angle relative to the overspeed sensor roller 8. The outer ends of the pair of passenger spacing rollers 6 are both H-shaped.
[0025] The right side roller hanger 9 is slidably connected with an anti-runaway brake device 10, and a buffer device 11 is installed between the anti-runaway brake device 10 and the roller hanger 9 located on the right side. The sliding connection can be achieved by setting a slide groove on the mounting plate to limit the anti-runaway brake device 10 from sliding in the direction of the wire rope movement. The model of the anti-runaway brake device 10 in this embodiment is GSZDX-150-L. That is, the anti-runaway brake device 10 is connected to the right side roller hanger 9 through the mounting plate, and the anti-runaway brake device 10 can slide through the slide groove set on the mounting plate. The anti-runaway brake device is installed on the mounting plate. Figure 1 Between a pair of supporting wheel hangers 9, Figure 1 The moving direction of the middle steel wire rope is from left to right. The buffer device 11 comprises a spring shock absorber and an I-beam, the spring shock absorber is mounted on the I-beam, and the I-beam is mounted on the supporting wheel hanger 9 located on the right side.
[0026] The signal line of the electromagnetic induction speed sensor 4 and the power line of the anti-runaway brake device 10 are both connected to the mine flameproof and intrinsically safe controller 12. The model of the mine flameproof and intrinsically safe controller 12 in this embodiment is KXJ660 mine flameproof and intrinsically safe controller. The mine flameproof and intrinsically safe controller 12 and the comprehensive protection device 13 are connected with a signal line. The mine flameproof and intrinsically safe controller 12 transmits an overspeed signal to the speed sensor 4, the mine flameproof and intrinsically safe controller 12 transmits a brake signal to the anti-runaway brake device 10, and the mine flameproof and intrinsically safe controller 12 transmits a shutdown signal to the comprehensive protection device 13.
[0027] When in use, after the overhead passenger device is started, the steel wire rope 5 drives the passenger spacing supporting wheel 6 on the passenger spacing hanger 1 to rotate, and at the same time, the overspeed sensor supporting wheel 8 also rotates with the movement of the steel wire rope 5, and the speed sensor 4 monitors the rotation of the overspeed sensor supporting wheel 8, thereby realizing the detection of the rotation of the passenger spacing supporting wheel 6.
[0028] Once the overhead passenger device runs away, the pulses collected by the speed sensor 4 are transmitted to the mine-used flameproof and intrinsically safe controller 12. If the mine-used flameproof and intrinsically safe controller 12 finds overspeed after comparing the speed with the internal normal maximum speed, the mine-used flameproof and intrinsically safe controller 12 supplies power to the anti-runaway brake device 10 and sends a stop signal to the comprehensive protection device 13. After the anti-runaway brake device 10 is powered on, it starts to perform the braking action to hold the wire rope.
[0029] The utility model device realizes that when the overhead passenger device has a runaway phenomenon, the speed sensor 4, the anti-runaway brake device 10 and the comprehensive protection device 13 can respectively perform timely and effective actions with the help of linkage information.
[0030] If the fixed cable grip hits the anti-runaway brake device 10 during the braking action, the buffer device 11 connected to the anti-runaway brake device 10 can be used for buffering protection. The fixed cable grip hits the anti-runaway brake device 10, squeezing the spring shock absorber to contract. The spring shock absorber uses its elastic buffering effect to buffer the movement of the fixed cable grip, thereby playing a buffering protection role. At the same time, the comprehensive protection device 13 drives the overhead passenger device to perform shutdown protection through a shutdown signal.
[0031] The preferred solution is to add a speed sensor 4 at other positions of the overspeed sensor supporting wheel 8. When the phase difference of the pulses transmitted by the two speed sensors 4 to the mine-used flameproof and intrinsically safe controller 12 changes, it indicates that the rotation direction of the overspeed sensor supporting wheel 8 has changed, that is, the overhead passenger device has rotated. At this time, the mine-used flameproof and intrinsically safe controller 12 sends a shutdown signal to the comprehensive protection device 13.
[0032] The above is only a specific implementation of the utility model, which enables those skilled in the art to understand or implement the utility model. Although detailed descriptions are given with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
