The working principle of the explosion-proof storage battery electric locomotive for the underground coal mine provided by the invention is as follows:
s1, when the electric locomotive is used, when a worker can control the electric locomotive to run, the connection pump 24 can be controlled to work, at the moment, the connection pump 24 can input a water source in the water tank 21 into the drainage plate 25 through the connection hose and spray the water source outwards through the drainage plate 25, at the moment, the discharged water source can adsorb suspended matters in the coal mine floating above the track on water drops, at the moment, the floating matters can fall onto the ground through the gravity of the water drops, and the roller 28 is extruded at the same time, so that the falling matters can be rolled and tightly adsorbed, and the phenomenon that the water drops float in the air again after being dried can be further reduced;
s2, when the electric locomotive moves forward, the coil 63 wound on the outer wall of the iron core 62 can be electrified, a magnetic field appears at two ends of the iron core 62, and the iron sheet at the bottom end of the iron core 62 can have magnetism through the generation of the magnetic field, so that the iron sheet can adsorb metal substances such as iron filings and the like on a track in the process of moving the electric locomotive;
s3, the wheels of the electric locomotive can be connected with the gear A56 to rotate through transmission between the belt 59 and the wheel disc A53 in the running process, at the moment, the gear A56 can smoothly mesh with the gear B57 below to rotate, and the wheel disc B55 can be driven to rotate through the wheel disc C58 and the belt 59 through the rotation of the gear B57, so that the wheel disc B55 can smoothly drive the cleaning brush 54 to rotate in the direction opposite to the running direction of the electric locomotive, therefore, the cleaning brush 54 smoothly cleans dust above the track in front of the electric locomotive, the wheels of the electric locomotive can be in contact with the track more comprehensively, and the running stability of the electric locomotive can be improved to a certain degree;
s4, when the electric locomotive brakes, the worker can directly control the hydraulic ejector 8 to work, at this time, the hydraulic ejector 8 can drive the connecting plate 8a to slide downwards in the fixing strip 8B, at this time, the fixing strip 8B can drive the parking brake roller 41 to move towards the direction close to the ground through the telescopic rod B8c, when the parking brake roller 41 contacts with the ground, the friction force will drive the parking brake roller 41 to rotate, at this time, the parking brake roller 41 will drive the connecting shaft rod 42 and the torsion spring 43 to rotate, the torsion spring 43 can be forced up through the rotation of the torsion spring 43, along with the gradual increase of the number of rotation turns of the torsion spring 43, the required power will also be increased accordingly, and further the resistance of the parking brake roller 41 to rotate can be increased gradually, through the increase of the rotation resistance of the parking brake roller 41, the inertia force in the braking process of the electric locomotive can be further consumed, the braking purpose of the auxiliary electric locomotive can be achieved, so that the braking effect of the electric locomotive is more excellent;
s5, and when the electric locomotive brakes, the staff still can control fan 33 and carry out work simultaneously, fan 33 can blow the wind-force that produces to the wheel through exhaust hood 35 this moment, the wind-force of flow direction wheel not only can carry out the heat dissipation of certain degree to the wheel, avoid the electric locomotive to stop the operation, the wheel is scalded, cause the phenomenon that the staff scalded, still can blow the noise that sends when the wheel brakes to in inhaling the sound cotton 32, inhale the sound cotton 32 and can carry out the isolated of certain degree to the noise of wheel braking in-process, reduce the sound of dazzling noise, and then can reduce the noise and bring uncomfortable phenomenon for the staff, so far can accomplish the use of this device.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
