(2) pay attention to the operation of the slag scraper at any time ring its operation, do not make the slag scraper operate with diseases, timely and correctly analyze, judge and deal with problems, so as to nip the accident in the bud. If it can't be handled, it should immediately report to the leader truthfully, and cooperate with the relevant personnel to analyze the cause of the fault and remove the difficult fault without delay
(3) in the work, we should concentrate on the correct and careful operation of the slag scraper, pay attention to the changes of the coal seam and roof and floor, and stop the machine immediately in case of roof fall and rib spalling, so as to assist the support worker to deal with it in time
(4) ring the operation, inspection, maintenance and troubleshooting of slag raking machine, it is necessary to pay attention to relevant safety matters to ensure work safety
(5) under no circumstances should the slag scraper be operated by personnel without a license. When the slag scraper needs to stop working or replace the digging teeth or overhaul, it must be shut down according to the safety requirements
(6) in the work, we should refuse the instruction of illegal operation, and dissuade and stop others' illegal operation
(7) to actively participate in various safety activities, post technical training, improve safety awareness and skills, report accidents in time, and protect the scene
(8) have the knowledge of coal mine disaster prevention and self rescue, mutual rescue and on-site first aid, take safety and first aid measures immediately in case of accident, actively carry out self rescue and mutual rescue, prevent the situation from expanding, protect the scene, and report to the superior immediately
(9) strictly implement the on-site shift handover system. In addition to carefully filling in the operation log and accident records, the operation of the unit equipment in this shift should be told to the next shift driver in detail, so as to pay attention to the next shift processing and operation.

1 There are two operating handles on the console. The front and back direction of the right handle controls the forward and backward movement of the trolley, and the left and right direction controls the up and down tilting movement of the slag raking arm. The front and back direction of the left handle controls the pulling down and lifting of the slag raking plate, and the left and right direction controls the left and right swing of the frame. The proportional valve is pushed forward and backward by the right handle, which can control the running speed of the car according to the pushing angle. The larger the pushing angle is, the faster the speed is; The other directions of the two handles push and control the reversing valve, which can only change direction but not speed. The speed adjustment is pre adjusted by the throttle valve in the hydraulic system
(2) there is a limit switch at the front end of the rack, and the car will stop automatically when the switch is knocked down. Due to the different movement speed of the operating trolley, the inertia effect will make the trolley stop at different distances. The front travel switch position is generally set after the medium speed impact to stop the trolley without hitting the buffer. In actual operation, e to the limitation of ladle position, the trolley does not need to go to the front limit position. There are two limit switches at the rear end of the rack. The front one is a deceleration switch. After knocking it down, it will output a signal to control the car to decelerate. When the car hits the rear limit switch, it will stop quickly
(3) a limit switch is set for the left and right swing of the rack, and one controls the maximum working angle of 10 °， The other controls the maximum turning angle of the maintenance station 45 °， The corner of the maintenance station can be set according to the actual needs of the workplace< (4) the distance between the tilting of the slag removing arm and the driving of the slag removing plate is limited by the maximum stroke of the hydraulic cylinder
(5) on the adjusting screw joint of the trolley Ф Pin 10 is a safety pin. In case of abnormal situation, the pin will be cut off to protect the hydraulic motor, chain and other parts when the force on the transmission system exceeds 2-3 times of the designed slag removal force. If the safety pin is cut off, it is necessary to analyze the cause of the accident and formulate solutions before the structure can be restored
(6) the hydraulic system of the driving system of the slag scraper has the function of overload protection, and the system pressure shall not exceed the design pressure when in use
(7) the travel switch of the trolley can be set to meet the slag removal travel, so the trolley can not often impact the spring buffer device
