What is the principle of braking device of harrow loader?

Precautions for safe operation of scraper? 1, the driver of the scraper loader must be familiar with and master the structure, performance, operation process and precautions of the loader, and only after passing the training and examination can he hold relevant certificates. ? 2. During rock loader operation, the farthest distance from the head-on shall not exceed15m, and the nearest distance shall not be less than 6m, usually 7-9m. The rake loader can still be used when encountering a curve. ? 3. Before work, drill a hole in the upper part of the head and install a fixed wedge. When installing, first put the tapered end of the wire rope collar into the eye, then insert the tight wedge and knock it tightly. When disassembling, hit the tight wedge with a hammer to loosen it. Pull out the tight wedge first, and then pull out the wire rope. ? 4. After the fixed wedge is installed, the tail wheel can be hung, and the tail wheel is hung on the ring of the wedge. The hanging height on the head-on rock pile is generally 800 ~ 1000 mm, and the hanging position can be moved left and right to clear the rocks in the roadway. ? 5. When hanging and unloading the tail wheel, loosen the auxiliary brake spring at the edge of the winch drum first, so as to manually pull the wire rope, and then tighten the spring after hanging and unloading the tail wheel to prevent the rope from being disorderly. ? 6. After the tail wheel is installed, the equipment shall be inspected for safety, and the work of rock loading and Sichuan recovery can only be started after it meets the standards. 7. Before driving, the driver should send a signal to remind others to confirm that there is no one else in front of and on both sides of the loader before turning on the motor for rock loading. ? 8. When working, tighten the joystick of the working drum, and the working drum will pull the scraper to pick up the rocks and unload them into the mine car along the groove. Loosen the operating lever of the working drum and tighten the idling operating lever to return the scraper to the head. Then tighten the operating lever of the working drum, and then enter the next cycle. The harrow loader produced by Shandong China Coal Company is of good quality. 9. When operating, the joystick should be gradually tightened and relaxed. Don't tighten both joysticks at the same time to prevent the scraper from flying out or rebounding from broken rope. ? 10, in the process of rock excavation, if the scraper is blocked or overloaded too much, don't forcibly pull it, and return the scraper before excavation. ? 1 1. After the completion of rock loading, put the rake in front of the loader, then put the two handles for manipulating bacteria on the brake release, take them off and put them on the trolley, and then cut off the power supply. ? 12, before shooting, the scraper loader should be evacuated to a safe place; After blasting, move the scraper loader forward and sprinkle water on the coal (rock) pile and two sides to prevent dust. At the same time, the chute and cable of the pulley device must be checked to meet the specified requirements before starting the car. ? 13. The scraper loader must be equipped with airborne lighting equipment, and it is not allowed to be used without all lighting equipment. ? 14. During the operation of the scraper, care must be taken not to let the wire rope damage the ram. Suspension of complaints? 15. During the use of this machine, sparks are easily generated due to the friction collision between wire rope and wire rope, wire rope and pulley, chute and rock. Therefore, we should strictly abide by and implement the relevant provisions of the "Coal Mine Safety Regulations" in the process of use. Only when the gas concentration in the working face is lower than 65438 0% can work be allowed, otherwise, stop, cut off power and evacuate people.
