Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coal mine transportation safety underground, and in particular relates to a coal mine transportation ground stop device and a use method thereof. BACKGROUND

[0002] Mine hoisting refers to transporting ore, coal, waste rock or gangue, and lifting personnel, equipment and materials along the mine shaft. The classification of mine hoisting methods is shown in the table. Among them, the steel wire rope hoisting is the most widely used, and the steel wire rope varieties include phosphating coated steel wire rope, galvanized steel wire rope and smooth steel wire rope.

[0003] In the mining process, the transportation device such as a mine car generally transports through a track. Due to the special working environment and characteristics, the transportation device often works in an uphill or downhill state. When the transportation device is in an uphill or downhill working state, if the transportation device needs to stop at a reasonable safety position, a ground stop device is needed to block the movement of the transportation device. For example, a coal mine transportation ground stop device disclosed in a Chinese patent (Patent No. CN 211844439U) solves the technical problem of the hazards of the derailment and runaway car accident. In addition to the damage to the shaft and the cable, air pipe, water pipe and other facilities along the lane, the working personnel may be injured or killed, causing personal injury and death accidents. The patent solves this technical problem through the mutual cooperation of the ground stop plate, the first spring, the second spring and the second rack. However, the patent still has some deficiencies. Since the impact force applied by the mine car on the ground stop plate has many uncontrollable factors, the single use of the spring for buffering may cause some problems due to the single spring elastic coefficient. When the spring strength is large, the ground stop plate may easily cause the mine car to receive a relatively strong reaction force in the instant of contact with the mine car. When the spring strength is small, the buffering effect is poor. In addition, when the mine car collides with the ground stop plate, side slipping may occur. Therefore, there is an urgent need for a coal mine transportation ground stop device and a use method thereof to solve the above problems. SUMMARY

[0017] A use method of a coal mine transportation ground baffle device, comprising the following process flow:

[0018] Step S1: when the second ground baffle is subjected to the impact force from the side away from the first ground baffle, on the one hand, the bottom end of the first ground baffle rotates about the first pin shaft, and the bottom end of the second ground baffle rotates about the second pin shaft, and in the process, the second side plate seat slides in the first sliding groove through the first sliding seat, and on the other hand, the top of the first ground baffle and the top of the second ground baffle can move relative to each other about the first adapter shaft, the included angle between the first ground baffle and the second ground baffle decreases, and in the process, the torsion spring is deformed under the action of the first adapter shaft, and the elastic effect of the torsion spring is utilized to achieve a certain buffering effect through the second ground baffle, so as to weaken the power generated by the gravitational potential energy of the mine car;

[0019] Step S2: when the included angle between the first ground baffle and the second ground baffle is in the process of decreasing, the first adapter shaft acts a torsion on the first gear, and the linkage effect between the first gear and the second gear is utilized, so that the torsion can be applied to the second adapter shaft, so that the second adapter shaft stably rotates in the third bearing, the second adapter shaft drives the inner side of the winding coil permanent magnet seat to rotate, thereby generating an electric current, and the sleeve, the contact piece and the wire are used to introduce the electric current into the electromagnet;

[0020] Step S3: the electromagnet generates a magnetic pole after being connected to the electric current, and the magnetic pole is the same as the magnetic pole of the side of the permanent magnet ring close to the electromagnet. According to the principle that like poles repel each other, the permanent magnet ring moves away from the electromagnet. In the process, the sliding sleeve drives the second sliding seat to slide in the second sliding groove through the bridge-shaped connecting frame, and because the two ends of the buffer shaft can rotate about the third pin shaft and the fourth pin shaft respectively, the bottom end of the second ground baffle has a tendency to move away from the first ground baffle, so that the magnetic relationship between the permanent magnet ring and the electromagnet can achieve good buffering effect. The greater the impact force on the second ground baffle, the faster the second gear rotates, the stronger the electric current, and the greater the magnetic interaction between the electromagnet and the permanent magnet ring. The buffering strength can be automatically controlled according to the strength of the external force acting on the second ground baffle. Compared with the single use of spring for buffering in the past, some problems caused by the single spring elastic coefficient can be avoided. When the spring strength is large, the second ground baffle is easy to cause the mine car to receive a relatively strong reaction force when it contacts the mine car. When the spring strength is small, the buffering effect is poor, and the impact force of the mine car on the second ground baffle is uncontrollable in terms of angle, and the buffering effect is good.

[0021] Step S4: the buffer pad has good elasticity and plasticity, which not only can achieve a certain buffering effect, but also can make part of the external mine car collide with the second ground baffle embedded in the buffer pad, so as to prevent the mine car from sliding sideways due to unstable force direction.

[0024] 2、The first ground baffle plate, the second ground baffle plate, the torsion spring, the first pin shaft, the second pin shaft, the first sliding seat and the first sliding groove are designed, when the second ground baffle plate receives the impact force from the mine car away from the first ground baffle plate, on the one hand, the bottom end of the first ground baffle plate rotates around the first pin shaft, the bottom end of the second ground baffle plate rotates around the second pin shaft, and in this process, the second side plate seat slides in the first sliding groove through the first sliding seat, on the other hand, the top of the first ground baffle plate and the second ground baffle plate can rotate around the first adapter shaft, the included angle between the first ground baffle plate and the second ground baffle plate is reduced, and in this process, the torsion spring is deformed under the drive of the first adapter shaft, the elastic effect of the torsion spring is utilized, and the second ground baffle plate can play a certain buffer effect and weaken the power strength generated by the gravitational potential energy of the mine car.
