Chapter V installation of dispatching, double speed and return winch
Article 32 the installation of dispatching, double speed and return winch must meet the following standards:
1. When using jd-25 and above winch, it must be fixed with concrete foundation or ground anchor. The foundation design shall meet the design requirements of winch manufacturer, and the foundation size and anchor screw shall be constructed according to the specification
2. The installation of jd-11.4 small winch should be determined according to the lithology of roadway floor:
(1) for the roadway with hard sandstone floor, the winch can be fixed by bolting
(2) for the roadway with medium hard sandy shale floor, the method of bolting can also be used to fix the winch, but the ground anchor can only be used after the anchoring force test
(3) for long-term permanent winch and roadway with soft rock and coal floor, concrete foundation can be used to fix the winch
(4) the column pressing winch can only be used when it moves along with the advancing of the mining face, and its number should be increased
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
