Description

Movable tail belt conveyor

Technical Field

The utility model relates to a belt conveyor, especially a portable tail belt conveyor for operating mode such as different coal bunkers divide the material or transport need be carried out when belt feeder conveyer transports.

Background

According to belt feeder transportation problem in the mine production process, need the belt feeder to carry out the gangue separation occasionally or transport raw coal and carry out depositing of different coal bunkers, and original belt conveyor coal discharge point is the fixed point, and mine bottom space is narrow and small, can't carry out tee bend branch coal design to original coal discharge point, so only another overlap joint belt feeder carries out the design transformation behind the coal discharge point, and work is very inconvenient.

Disclosure of Invention

The utility model aims at: the utility model provides a portable tail belt conveyor, the tail passes through electro-hydraulic push rod pulling tail frame, move to the aircraft nose direction, fall into the coal bunker under the coal discharge point in order to satisfy direct coal discharge, when the coal bunker capacity under the coal discharge point is full, the tail promotes tail frame through electro-hydraulic push rod and moves to the aircraft nose opposite direction, the belt coal breakage point raw coal falls into on belt conveyor this moment, through belt conveyor to aircraft nose direction transportation, unload newly-built coal bunker, it is limited because of coal bunker mouth space in the pit to solve through this kind of mode, can't install transportation problems such as tee bend coal distributor additional.

Realize the utility model discloses the technical scheme that the purpose was taken is: the electric hydraulic push rods are horizontally arranged on the ground in front of the tail roller, and the front ends of the electric hydraulic push rods are respectively connected to two sides of the tail roller frame; six fixed pulleys correspond to each other in pairs, four corresponding tail roller frames are arranged on a roadway top plate above the tail roller frames, and two fixed pulleys are arranged on a floor behind the tail rollers; one ends of two steel wire ropes are respectively fixed at two ends of the movable lower carrier roller, the two steel wire ropes respectively pass around two fixed pulleys on a top plate of the roadway and then pass around two fixed pulleys on a bottom plate and are respectively fixed at two sides of a tail roller frame; the two rails are mutually parallel and fixed on the ground of the roadway, the tail roller frame is placed on the rails, and the tail roller frame is connected with the rails in a sliding mode.

The utility model has the advantages that: structural design is reasonable, and the preparation of conveniently processing can solve because of space restriction in the pit, can't use the tee bend tripper to divide the material problem, and this device can satisfy daily colliery belt feeder raw coal reposition of redundant personnel in the pit, can remote control, and unmanned on duty can solve belt feeder operating safety factor.

Drawings

FIG. 1 is a front view of the mobile tail raw coal of the present invention transported by a belt conveyor; FIG. 2 is a front view of the movable machine tail coal directly falling into the coal bunker.

In the figure: 1-adhesive tape, 2-electric hydraulic push rod, 3-electric hydraulic push rod base, 4-movable lower carrier roller, 5-steel wire rope, 6-fixed pulley, 7-ground anchor, 8-tail roller frame, 9-rail, 10-first coal bunker, 11-pin shaft, 12-coal flow indication, 13-second coal bunker, 14-roller frame, 15 transmission roller, 16 carrier roller group, 17 middle frame, 18 supporting legs and 19 parallel lower carrier roller.

The specific implementation mode is as follows:

the utility model discloses by driving pulley 15, conveyer belt 1, bearing roller group 16, roller frame 14, intermediate frame 17, landing leg 18, parallel snub pulley 19, electro-hydraulic push rod 2, wire rope 5, fixed pulley 6, activity snub pulley 4, track 9, tail roller frame 8 constitutes, tail mobile power source adopts two sets of electro-hydraulic push rods 2 (electro-hydraulic push rod is a hydraulic drive manipulator that collects machine, electricity, liquid as an organic whole), two electro-hydraulic push rods 2 level are fixed on the ground in front of the tail roller, the axle 11 is distributed to the front end of electro-hydraulic push rod 2 and is connected respectively in tail roller frame 8 both sides; six fixed pulleys 6 correspond to each other in pairs, four corresponding tail roller frames 8 are fixed on a roadway top plate through ground anchors 7, and the other two fixed pulleys are fixed on a floor behind a tail roller; one ends of two steel wire ropes 5 are respectively fixed at two ends of the movable lower carrier roller 4, respectively bypass two fixed pulleys 6 on a top plate of a roadway, respectively bypass two fixed pulleys 6 on a bottom plate, and are respectively fixed at two sides of a tail roller frame 8; two tracks 9 are parallel to each other and are fixed in the tunnel subaerially, and tail roller frame 8 is placed on track 9, and the pulley is installed to tail roller frame 8 bottom, can make a round trip to slide on track 9, and the design of 8 both sides of tail roller frame has the track cardboard, can avoid the track that drops when tail roller frame 8 round trip movement.

The utility model discloses a working process: firstly, a second coal bunker 13 is designed and built in front of the coal bunker just below a discharge opening, when an electric hydraulic push rod 2 is in an extending state (as shown in attached drawing 1), a machine tail roller frame 8 is pushed to move backwards, the machine tail roller frame 8 drives a rubber belt 1 to move backwards, a conveying belt 1 drives a movable lower carrier roller 4 to move downwards, the movable lower carrier roller 4 drives a steel wire rope 5 to slide and move through a fixed pulley 6, the steel wire rope 5 is enabled to be in a tensioning state, raw coal at a coal dropping point 12 in the state just falls on the conveying belt 1 above the machine tail roller frame 8, and the raw coal is conveyed to the lower second coal bunker 13 through a movable machine tail belt conveyor 14. When the movable machine tail belt conveyor 14 stops, the conveying belt 1 is in a static state, the electric hydraulic push rod 2 is in a withdrawing state (as shown in the attached drawing 2), the machine tail roller frame 8 is pulled to move forwards, the machine tail roller frame 8 drives the steel wire rope 5 to slide through the fixed pulley 6, the movable lower carrier roller 4 is driven to move upwards during sliding, the movable lower carrier roller 4 can drive the conveying belt 1 to ascend for 2 meters by moving upwards for 1 meter, the conveying belt 1 can be ensured to be in an extending state, the use safety of the conveying belt is ensured, and the raw coal at the coal dropping point 12 can directly fall into the first coal bunker 1. The reciprocating motion can solve the material distribution problem of the blanking point.
