4. Check the pressure switch, relay, limit switch and other electrical system parts for normal operation
5. Check the support part of the whole system piping ymjt01 for looseness and vibration
6. Touch the joint by hand to check whether there is oil leakage, and check whether there is oil leakage in the piping.
The suitable cross section of the tyre scraper is 1.6 * 1.6m; 1.8 * 1.8m; 2 * 2m section
suitable section of rail loader: 80 type 1.8 * 1.8m; 100 type 2.5 * 2.5m; 120 type 2.4 * 2.5m; 150 type, 2.5 * 2.8m; 160 Type 3.2 * 3.2m section. The selection of this model is mainly based on the mechanical equipment used to transport ore [such as rail transport, bucket car transport, shuttle car transport, etc.]
suitable section of crawler excavator loader: 80 type 2 * 2.2m; 100 type 2.6 * 2.6m; 100 type 2.2 * 2.4; 120 type 2.3 * 2.6m; 120 type 2.8 * 2.8; 150 type, 2.5 * 2.9m; 150 type 3.5 * 3.5m; 180 type, 2.8 * 3.3m; 180 type, 3 * 4m; 180 type, 4 * 4m; 200 type 4 * 4m; 220 type 4.5 * 4.5m; 260 type 5 * 5m; 312 type, 5 * 5m; 330 type 5 * 5m section
suitable section for inclined shaft with large slope: 80 crawler type 2.4 * 2.5m section with maximum working slope of 30 degrees; The maximum working gradient of 100 crawler type 2.6 * 2.6m section is 25 degrees; 120 crawler type 2.4 * 2.4m, maximum working gradient 28 degrees; 150 crawler type 3.5 * 3.5m, maximum working gradient 28 degrees; The maximum working gradient of 4 * 4m section of 180 crawler type is 32 degrees; 120 crawler type 2.8 * 2.8m, maximum working gradient 32 degrees; The maximum working gradient of 312 crawler type 5 * 5m section is 30 degrees
the main equipment commonly used in the construction of large section or full section are as follows:
rail transportation: gantry drilling jumbo, bolt support, vertical claw or rake bucket rail type rock loader (slag loader), 10 ~ 30 cubic shuttle mine car or mining big bucket car, 12 ton or 25t traction motor car, concrete spraying machine or transport pump, steel formwork jumbo combined supporting construction
trackless transportation: 3-arm or 4-arm tire and crawler electric hydraulic rock drilling jumbo, shotcrete anchor support, anchor jumbo, bucket crawler loader, 20 ~ 25 ton mining truck or pit truck [small secondary wheel and small Dongfeng], concrete spraying machine or delivery pump, integral steel formwork jumbo
the advantages of trackless shipping are high proction efficiency, good mobility, overcoming the practical advantages of working with large slope, small turning radius, strong working force, fast speed, not subject to conditions and so on. Although the initial investment is relatively high, the construction cost is low and fast, the engineering quality is good, and the safety and environmental protection are constantly improving. It is a common construction method in underground construction
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
