Description
Technical Field

Background
The inclined roadway transportation is one of important links in coal mine production transportation, and is used for carrying the tasks of pedestrians, gangue lifting or material transportation. For the inclined roadway rail transportation winch, once accidents such as derailment and derailment of vehicles occur, serious threat is caused to the safety of personnel and equipment in the inclined roadway, and the normal production of a mine is seriously affected. The existing method for detecting the derailment of the mine car only detects the magnitude of the pulling force applied to the pulling rope through the pulling force sensor to judge whether the mine car derails, and has the defect that the preset value for judging the pulling force cannot accurately judge the derailment fault because the weight of the goods transported each time in the actual transportation process is different from the number of the mine cars, namely the heavy load normal operation pulling force interval and the light load derailment operation pulling force interval are overlapped.
In the prior art, the weight of goods transported each time in the actual transportation process is different from the number of mine cars, and the preset value for judging the tension cannot accurately judge the derailment fault.
Disclosure of utility model
The utility model aims to provide a system for detecting whether a mine car falls off in an inclined roadway or not, so as to solve the problem that the falling off fault cannot be accurately judged due to the fact that the weight of goods and the number of the mine cars are different in each transportation in the actual transportation process in the prior art.
The utility model adopts the following technical scheme that the system for detecting whether the inclined roadway transportation mine car falls off is characterized in that a plurality of mine cars are sequentially connected, the mine car at the forefront side is connected with a shuttle car, the shuttle car is used for driving the mine car to travel forwards along a rail, and a detection plate is fixedly connected to the mine car at the rearmost side;
the system comprises:
The laser ranging sensor is arranged at the bottom of the shuttle car and is close to the track and used for measuring the standard distance between the shuttle car and the detection plate and measuring the measuring distance between the shuttle car and the mine car after derailing;
the processing module is used for receiving the standard distance and the measured distance of the laser ranging sensor, and sending an alarm signal when the measured distance is smaller than the standard distance;
And the alarm module is used for receiving the alarm signal and sending an action signal to the head control box of the shuttle car so that the shuttle car starts to alarm and stop in a locking way.
Further, two laser ranging sensors are arranged and respectively installed on two sides of the shuttle car, and laser beams of the two laser ranging sensors are respectively close to two sides of the mine car.
The system further comprises a calculation module, a laser ranging sensor, a mining car positioning module and a control module, wherein the calculation module is used for receiving the measured distance of the laser ranging sensor, calculating a mining car positioning value according to the measured distance/the preset length of the mining car, and judging the position of the derailment according to the number of units of the numerical value.
The beneficial effects of the utility model are as follows:
The utility model measures the standard distance between the shuttle car and the detection board and the measured distance between the shuttle car and the mine car after the derailment occurs through the laser ranging sensor, then processes the signals by utilizing the processing module, and sends an alarm signal when the measured distance is smaller than the standard distance;
The utility model can accurately judge whether the mine car falls into the road or not and automatically alarm to stop the car, regardless of the number and the carrying capacity of the mine car pulled in the transportation process;
The utility model can also calculate the mine car positioning value according to the calculation module, and then judge the position of the derailing mine car according to the mine car positioning value.
