Description

Technical Field

[0001] The utility model belongs to the field of inclined tunnel winch rail transportation, in particular to a system for detecting whether an inclined tunnel transportation mine car has fallen off the track. Background Art

[0002] Inclined tunnel transportation is one of the important links in coal mine production and transportation. It is responsible for tasks such as carrying pedestrians, lifting gangue or transporting materials. For inclined tunnel rail transportation winches, once a runaway car or vehicle derails or falls off the track, it will pose a serious threat to the safety of personnel and equipment in the inclined tunnel, and seriously affect the normal production of the mine. At present, the only method for detecting the derailment of a mine car is to detect the tension on the traction rope through a tension sensor to determine whether the mine car has derailed. Because the weight of the goods and the number of mine cars transported each time in the actual transportation process are different, that is, the tension range of normal operation with heavy load and the tension range of derailment with light load overlap, the preset value of the tension cannot accurately determine the derailment fault.

[0003] In the prior art, since the weight of the goods and the number of mining cars transported each time are different during the actual transportation process, the preset value for judging the pulling force cannot accurately judge the derailment fault. Utility Model Content

[0004] The utility model aims to provide a system for detecting whether a mine car transporting in an inclined tunnel has derailed, so as to solve the problem in the prior art that the preset value of the pulling force cannot accurately determine the derailment fault due to the different weights of the goods transported each time and the number of mine cars in the actual transportation process.

[0005] The utility model adopts the following technical scheme: a system for detecting whether a mine car transporting an inclined tunnel has fallen off the track, wherein a plurality of mine cars are connected in sequence, and the mine car at the front side is connected to a shuttle car, the shuttle car is used to drive the mine car to move forward along the track, and a detection plate is fixedly connected to the mine car at the rear side;

[0006] The system includes:

[0007] The laser distance sensor is installed at the bottom of the shuttle car and close to the track. It is used to measure the standard distance between the shuttle car and the detection plate. It is also used to measure the distance between the shuttle car and the mine car after it has fallen off the track.

[0008] A processing module, used for receiving the standard distance and the measured distance of the laser distance measuring sensor, and sending an alarm signal when the measured distance is less than the standard distance;

[0009] The alarm module is used to receive the alarm signal and send an action signal to the shuttle car head control box, so that the shuttle car starts to alarm and lock and stop.

[0010] Furthermore, two laser ranging sensors are provided and respectively installed on both sides of the shuttle car, and the laser beams of the two laser ranging sensors are respectively arranged close to both sides of the mining car.

[0011] Furthermore, it also includes: a calculation module, which is used to receive the measured distance of the laser ranging sensor, and calculate the mine car positioning value according to the measured distance / predetermined length of the mine car. The mine car positioning value is used to determine the position of the derailed mine car according to the size of the single digit of the value.

[0012] The beneficial effects of the utility model are:

[0013] The utility model measures the standard distance between the shuttle car and the detection plate, and the measured distance between the shuttle car and the mine car after the derailment through a laser distance measuring sensor; then uses a processing module to process, and when the measured distance is less than the standard distance, sends an alarm signal; the alarm module sends an action signal to the shuttle car head control box, so that the shuttle car starts to alarm and lock and stop;

[0014] The utility model can accurately judge whether the mine car has fallen off the track, and automatically alarm, lock and stop the vehicle, regardless of the number and load of the mine car being towed during transportation; thereby eliminating coal mine transportation safety accidents caused by the mine car falling off the track;

[0015] The utility model can also roughly calculate the mine car positioning value according to the calculation module, and then roughly determine the position of the derailed mine car according to the mine car positioning value. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0020] The utility model discloses a system for detecting whether a mining vehicle transporting in an inclined tunnel has fallen off the track. Figure 1 As shown, a plurality of mine carts are connected in sequence, and the mine cart at the front is connected to a shuttle car, which is used to drive the mine cart to move forward along the track, and a detection plate is fixedly connected to the mine cart at the rear.

[0021] The system includes: a laser ranging sensor 1, a processing module 2, and an alarm module 4.

[0022] The laser distance measuring sensor 1 is installed at the bottom of the shuttle car and close to the track. The laser distance measuring sensor 1 is used to measure the standard distance between the shuttle car and the detection plate; the laser distance measuring sensor 1 is also used to measure the distance between the shuttle car and the mine car after it has derailed.

[0023] The processing module 2 is used to receive the standard distance and the measured distance of the laser ranging sensor 1, and send an alarm signal when the measured distance is less than the standard distance; the alarm module 4 is used to receive the alarm signal and send an action signal to the shuttle head control box, so that the shuttle starts to alarm and lock and stop.

[0024] Two laser distance measuring sensors 1 are provided and respectively installed on both sides of the shuttle car. The laser beams of the two laser distance measuring sensors 1 are respectively arranged close to both sides of the mining car.

[0025] Two laser distance measuring sensors 1 are provided and installed on both sides of the shuttle car respectively to ensure that the laser distance measuring sensor 1 can detect the mine car running away immediately after the mine car runs away. If it is too far away, the laser distance measuring sensor 1 will not be easy to detect after the mine car tilts slightly. This is because a slight deflection may not block the light of the laser distance measuring sensor 1. It can only be blocked when a large deflection occurs, and a large deflection is likely to cause a running away accident.

[0026] The utility model also includes: a calculation module 3, which is used to receive the measured distance of the laser ranging sensor 1, and calculate the mine car positioning value according to the measured distance / predetermined length of the mine car. The mine car positioning value is used to determine the position of the derailed mine car according to the size of the single digit of the value.

[0027] The utility model measures the standard distance between the shuttle car and the detection plate, and the measured distance between the shuttle car and the mine car after the derailment through the laser ranging sensor 1; then uses the processing module 2 to process, and when the measured distance is less than the standard distance, sends an alarm signal; the alarm module 4 sends an action signal to the shuttle car head control box, so that the shuttle car starts to alarm and lock and stop; regardless of the number and load weight of the mine cars towed during the transportation process, the utility model can accurately determine whether the mine car has derailed, and automatically alarm and lock and stop, thereby eliminating coal mine transportation safety accidents caused by the mine car derailment.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
