Fixed Wedge: Fixed Wedge is fixed on the head, to hang the tail wheel, fixed wedge consists of a tight wedge and a rope ring with wedge tapered sleeve.
Tail Wheel: Hanging on the fixed wedge to guide the tail rope and make the rake bucket back to head. It mainly consists of main parts such as side plate, sheave, mandrel and hanger.
Scraper Bucket: The main rope, tail rope traction under the reciprocating motion to steal the rock, can be used for roadway and sloping roadway. Rake teeth can be replaced after wear.
Operating Mechanism: Consists of two sets of joystick, rod, adjusting screw and so on. One end of the adjusting screw is connected with the winch brake band, and the opening and closing of the brake band is controlled by the joystick, and the two drums of the winch are respectively operated. Lever can be installed on the left and right side of the winch for manipulation.
Winch: Winch of scraper loader consists of a motor, reducer and two planetary drive rollers with two sets of brakes and auxiliary brake belts. Actually, the brake acts as a clutch and controls the two rollers respectively.
During work, the brakes on the working drum are braked to stop the internal gear. The planetary gear rolls along the internal gear driven by the central wheel, so as to drive the drum to rotate and wind the rope to draw the rake bucket, the scraper bucket is loaded with material along the trough to the discharge port after the head is installed.
On the return trip, loosen the brake on the working drum and brake the brakes on the freewheeling drum, the tail rope is retracted head-on according to the above principle.
Due to the different numbers of gears in the two drums, the speed of the two drums is also different, and the free-running drum has a higher rope speed than the working drum.
In order to prevent the drum from rotating due to inertia and causing the rope to loop around the rope after stopping, two sets of auxiliary brakes are also arranged on the edges of the two rollers to prevent the drum from continuing to rotate due to inertia.
Trolley: Consists of frame, wheelset, bump and other components, it is rack and walkway of scraper loader, carrying full weight of rock loader. The trolley is equipped with a winch, a steering mechanism and a pneumatic system and also provided with a bracket and a pillar for supporting the middle slot. Four sets of rail guides are arranged on the front and the back of the trolley.
Guide Wheel, Roller: Installed in the middle and top of the scraper loader to guide and change the direction of the rope. It consists of side panels, sheaves, mandrels, rolling bearings and other components, and the use of dust-proof structure to extend its service life.
Feed Chute, Middle Chute, (intermediate Chute), Discharging Chute: is part of scraping rock mechanism, scraps taken from the rake bucket are sequentially unloaded to a mine car or a skip through the discharge port along feed chute, middle chute, (intermediate chute), discharging chute. The middle chute is installed on the trolley, feed chute, middle chute (intermediate chute), discharging chute is respectively connected before and after.
The middle of the feed chute is equipped with a lifting device for adjusting the height of the dustpan mouth. A baffle is arranged on the two front sides of the dustpan mouth to guide the rake bucket into the material trough.
Pneumatic System: In order to ensure the reliability of the pneumatic system, take the pressure filter, lubricator lubrication measures, penumatic system consists of coarse filter bag, oil mist, rotary valve, cart push clylinder which is mainly composed of a cylinder barrel, a piston rod, a piston, front and rear covers, a Y-shaped polyurethane sealing ring, etc. The air cylinder structure is provided on both the front and the back of the cylinder to ensure smooth movement. Prevent mine cars from damaging the piston rod when hit.
Electrical Section: The components used are mining explosion-proof, can be used in mines with methane and coal dust, consists of flameproof control box that adapted to industrial and mining conditions with large voltage fluctuation, anti-glare flameproof explosion-proof lights, explosion-proof control buttons, explosion-proof motor and other components.
Shunt Disk: To make the turnout and the yard closely follow the rake bucket rock loader. The shimming disc is a moving turnout floating on the track, which moves forward along with the progress of the rock scraper mounting rocker and utilizes the wind The winches and two pneumatic trolley cylinders make it possible to speed up shipping operations by mechanizing the shunting of empty and heavy trucks. Tune disc body consists of four wide 1200mm, 14mm thick steel assembled from the plate, the body is equipped with wind-driven shunting winch, empty cart trolley and air moving console and other components.
After blasting, first punch the hole in the head (or use the remaining hole), install the fixed wedge with first put wire end of the sleeve with a tapered sleeve into drilled hole, and then inserted into the fixed wedge and tapping, when demolition, with a hammer laterally tap the end of the tight wedge to loose, and then pull out the tight wedge and then wire rope ring. The hole for fixed wedges is preferably offset from the work surface by 5 ° to 7 ° so that the fixed wedge can not be easily pulled out.
Scraper loader used to tilt roadway rock loading, in addition to using the original rail device should add a stop device to prevent the decline of the machine to ensure safe and reliable.
In order to ensure a high productivity and easy to lay the track, 15m. In order to avoid blasting machine damage, the machine is generally not less than 6m away from head to head (Figure VI).
Trolley Movement: Rope of winch and air windlass of scraper loader go through sheave hanging on the track, with the bolt fixed in the side of the mine cart out of the steel plate hole, pulled out winch main rope and fixed on the rail. Then start and control the air winch and scraper winch, shunting disk and rake bucket rock loader to move backwards, until the track exposed dustpan mouth outside to stop. Scraper winch pulls rock loader and shunt disc to he place.
After installing the fixed wedge, the tail wheel can be hung on the wire rope collar, tail suspension position with the roadway depending on the situation, it is better to hang above the height of 1000 mm above the head rock.
When suspending and removing the rear wheel, loosen the auxiliary brake spring on the edge of the winch drum, pull the wire rope and hang the tail wheel until the tail wheel is hung and reset or adjust the spring to the proper pressure.
After installing the tail wheel and relevant safety inspection, start the motor to start rock loading operation, tighten drum joystick then the steering wheel will drag the rake head to take the rock, unloading into the mine cart along the chute to the discharge port, and then release the working drum joystick, tighten the free-wheel drum joystick, so that the empty rake bucket back to head, repeat rock scraping action for 2-3 times to fill a mine car.
(A) type rock scraper loader manipulate the pneumatic system of the rotary valve, with the pneumatic cart push cylinder to push the mine cart out. As used for equipping with a skip behind the inclined lane, you can add an intermediate slot between the middle chute and unloading chute, in order to change the position of the discharge port to fill the skip.
