Embodiment
As shown in Figure 2,3, the invention provides a kind of change length drag conveyor suitable for colliery edge coal mining,
Including head transmission component 1, tail transmission component 8, and it is sequentially connected that the head connect is special to become wire casing 3 and normal interlude 4,
The normal interlude 4 is connected by arc turning slot 7 with tail transmission component 8, so that can be by tail transmission group when mining
Part 8 is arranged in tail transportation roadway.
The special support 2 of head is wherein installed by head transmission component 1, and in the special change wire casing 3 of head, normal centre
Normal middle bracket 5 is installed by section 4 and arc turning slot 7.Arc turning slot 7 includes revolution cell body, and the revolution cell body is with pushing away
Connected between moving device by bearing pin, so as to promote revolution cell body movement.In addition lift is disposed with the bottom of tail transmission component 8
High device, and side shifter is there also is provided in the bottom of tail transmission component 8, pass through pin between the elevation device and side shifter
Axle is connected, so as to realize moving left and right for tail transmission component 8.
As shown in Figure 2,3, for scraper plate chain component 6, normally revolution provides chain road to the revolution cell body of arc turning slot 7, and arc is returned
The push unit of turn trough 7 is connected with normal middle bracket 5, is the movable offer power of tail transmission component 8.Turn round cell body
It is connected between push unit by bearing pin.Elevation device is evenly arranged in the center of gravity surrounding of tail transmission component 8 in addition, tail is passed
The dynamic bottom design side shifter of component 8, elevation device is connected with side shifter by bearing pin, realizes a left side for tail transmission component 8
Move right.By moving left and right, for progress increases and decreases normal interlude 4 at tail, the operation of normal fluid pressure support is provided enough
Space.
To realize scraper plate chain component 6 normally revolution and the movement of tail transmission component 8, arc turning slot is designed at tail
7, arc turning slot 7 is mainly made up of revolution cell body and push unit, is connected between revolution cell body and push unit by bearing pin.
The normal revolution of conveyer scraper chain is realized, the normal movement of tail transmission component 8 can be realized again.Pass through tail transmission component
The change of 8 positions, realizes at tail without special deflection section, the integral arrangement of special hydraulic support, realizes reduced echelon form work
The working face that need to be carried out when making face direction of propulsion length change increases frame, subtracts frame process, improves the once extraction in whole coalfield
Rate.
The present invention application method and operation principle be：
2,3 the present invention is further illustrated below in conjunction with the accompanying drawings：
As shown in Fig. 2 a kind of change length drag conveyor suitable for colliery edge coal mining of the present invention, including machine
Head transmission component 1, head are special to become wire casing 3, normal interlude 4, scraper plate chain component 6, arc turning slot 7, tail transmission component
8.By changing the arrangement of tail transmission component 8, design arc is returned between tail transmission component 8 and normal interlude 4
Turn trough 7 carries out the normal revolution of conveyer scraper chain, while arc turning slot 7 is connected with normal middle bracket 5, carries out tail biography
The normal movement of dynamic component 8.By such a arrangement, whole tail transmission component 8 is arranged in haulage drift, with working face into
" angle " is arranged, and " angle " arrangement can share the motor, decelerator, sprocket shaft group of same model with former " parallel arrangement "
Deng reducing the species of same model product.
As shown in Fig. 2 the present invention realizes fully-mechanized mining working surface conveyer tail transmission component 8 and is arranged in transport first
In tunnel, tail transmission component 8 is arranged in haulage drift, normal interlude 4 is realized with normal middle bracket 5 in work
Arrangement at the tail of face.Trapezoidal working face is simplified in progradation, the increase and decrease that need to be carried out when face length changes
Normal interlude 4 and the process of normal middle bracket 5.Tail haulage drift is set to be formed an angle along tomography or coalfield edge
Degree driving, working face is arranged as possibility in echelon.The drawing effectiveness of working surface tail termination is improved simultaneously, and coal energy is put in raising
Power, further improves coal recovery rate and a recovery ratio in coalfield.
As shown in figure 3, in the initial normal mounting of working face, tail transmission component 8 is arranged away from rib side, when trapezoidal
After advance of the face certain distance, tail transmission component 8 reaches certain safe distance with rib, now by normal middle bracket
5 along remote rib wing passage to the advance of the face, and is installed to specified location.Then tail transmission component 8 and arc are turned round
Groove 7 is overall to the distance moved away from rib side more than the normal length of interlude 4, now leads to normal interlude 4 along rib side
Road is installed to specified location to the advance of the face, and tail transmission component 8 returns to initial normal installed position, completes trapezoidal
Working face increases and decreases normal interlude 4 and the whole flow process of normal middle bracket 5.
Test proves that, conveyed using a kind of change length scraper plate suitable for colliery edge coal mining of the present invention
Machine, solves special deflection groove at existing conveying equipment tail, the problem of special supporting support is excessive, makes whole at whole tail
Normal interlude 4 and normal middle bracket 5 are installed, the trapezoidal arrangement of working face is realized, simplifies trapezoidal advance of the face direction
The increasing frame implemented during length change, subtract frame process, while improving termination drawing effectiveness, further improve coal resource reclaiming
Rate and a recovery ratio in coalfield.
The present invention realizes fully-mechanized mining working surface conveyer tail transmission component 8 and is arranged in haulage drift first, solves
Determined special deflection groove at existing conveying equipment tail, the problem of special supporting support is excessive, make all installations at whole tail
Normal interlude 4 and normal middle bracket 5, make tail haulage drift be tunneled along tomography or coalfield edge degree of forming an angle, work
Make face and be arranged as possibility in echelon.The drawing effectiveness of working surface tail termination is improved simultaneously, and coal ability is put in raising, further
Coal recovery rate and a recovery ratio in coalfield are improved, the labor intensity of workman is reduced, working face is reduced and increases frame, subtracts
The potential safety hazard of frame.
