Abstract
The utility model relates to a hydraulic support substituting for a shed, which is a support device for coal-mine tunnel and is applicable to the support outside the end head outlet of the fully-mechanised longwall work face, particularly an arc tunnel. The utility model is mainly composed of supporting mechanism, adjusting mechanism and hanging mechanism. The tunnels outside the end head outlet of the fully-mechanised longwall work face can be effectively maintained, and the utility model takes the place of wooden shed to replace and recover metal support of the tunnel to avoid secondary looseness of adjacent rocks and supporting repetition. Thus, large amounts of pit wood can be saved, the working conditions can be improved, per unit yield of the work face can be enhanced, and cost a be reduced. The utility model has the advantages of simple structure, convenient operation, light weight, and is convenient to realize replacement of semimechanization of the metal support of the tunnel.
Description
The utility model is a kind of colliery tunnel support equipment, is applicable to fully-mechanized mining working faces end head outlet supporting in addition, is specially adapted to arched tunnel.
At present,, replace and reclaim metallic supports in galleries in order to safeguard fully-mechanized mining working faces end head outlet tunnel in addition effectively, 20 meters of general requirements advance supports, and all adopt artificial timber set to replace metallic supports in galleries.And timber set does not have setting load, in the process of replacing metallic supports in galleries, makes the country rock secondary loosening, causes country rock further broken, the tunnel occurs and keeps in repair repeatedly.Generally can't reclaim for last timber set, particularly in order to guarantee effective support of face end support, arcuate part needs to enrich with mine timber, and these mine timbers almost all are lost in the goaf, make mine timber consumption quite serious, and working strength of workers is big, and efficient is low, and operation is dangerous, like this, have a strong impact on the performance of fully-mechanized mining equipment efficient, limited single face output, limited the raising of mine production efficiency.
The purpose of this utility model is to provide this hydraulic pressure to replace timber set for the canopy support, to close on the metallic supports in galleries of work plane replaces, thereby can safeguard the tunnel beyond the fully-mechanized mining working faces end head outlet effectively, safety work space and passage are provided, save a large amount of mine timbers, alleviate labor strength.
The purpose of this utility model is achieved in that this hydraulic pressure is made up of supporting mechanism, governor motion and hanging mechanism for the canopy support.
This hydraulic pressure mainly is made up of back timber, curb girder, connecting rod, face guard, column and post boots for the supporting mechanism of canopy support.Back timber, curb girder, connecting rod and face guard are hinged, and column is by carrying with curb girder is hinged in the middle of the connecting rod.
This hydraulic pressure mainly is made up of balance jack and wall supporting jack for the governor motion of canopy support.The effect of jack is the mutual alignment relation of regulating between each member of supporting mechanism.When for the reach of canopy support, the wall supporting jack can take column in one's arms by connecting rod, face guard.
This hydraulic pressure mainly is made up of knock-down hanging ring, circular orbit beam and roller for the hanging mechanism of canopy support.The circular orbit beam forms by the segmentation beam is hinged, and a tunnel is established one, forms the ring-type of a sealing.The circular orbit beam utilizes the hanging ring of each bracing frame to be suspended in the below of each bracing frame, for each bracing frame shared.When moving for the canopy support, shrink each jack and column, become the circular orbit beam and hang the support state, utilize a pair roller to roll along the circular orbit beam, make the support reach.Hanging ring can turn round arbitrarily around back timber.
The support principle that this hydraulic pressure is replaced the canopy support is: it has the bearing mode as metallic supports in galleries, can carry the different roadway surrounding rock pressure that distributes, both can bear the pressure that roof pressure equates with side pressure, also can bear the pressure of roof pressure greater than side pressure, also can bear side pressure greater than roof pressure and unbalance loading equal pressure, have the characteristics of the dynamic pressure of bearing simultaneously, when outside when carrying greater than supporting capacity, allow pressures for contracting under the canopy support, realize the constant-resistance support.
Hydraulic pressure is to make for the canopy support by governor motion to be retracted to the frame state that moves for the move mode of canopy support, and movable stand utilizes hanging mechanism two-way moving below other hydraulic pressure that is supporting replaces the canopy support.
Hydraulic pressure for the canopy support compared with prior art has the following advantages and economic effect:
1. be before not removing metallic supports in galleries for the canopy support, just first support between two metallic supports in galleries, and can select to be complementary for the setting load of canopy support and the support force of metallic supports in galleries, can avoid the loosening and support repeatedly of country rock secondary like this.
2. have good wall supporting ability for the canopy support, be convenient to prevent and manage the tunnel wall caving.
3. each that is hinged section beam body can be regulated according to different drift section shapes, has the good top performance that connects.
4. the arrangement form for the canopy support does not have strict center to center distance requirement, as long as be supported between two metallic supports in galleries, therefore can adapt to different metallic supports in galleries frame spacings.
5. use for the canopy support to replace mine timber to replace metallic supports in galleries, can obviously save mine timber, only this item can be regained equipment investment then, thereby directly reduce the coal cost.
6. its labor organization mode is decided by the scene custom, both can concentrate on backshift again and once finish the metallic supports in galleries process of replacing with adopting with replacing metallic supports in galleries.
7. this hydraulic pressure has good geology adaptive capacity for the canopy support, it is simple in structure, easy to operate, in light weight, be convenient to realize replacing the metallic supports in galleries semi-mechanization, can improve work situation, improve single face output, and not influence dash, pedestrian, transport normally carrying out of work such as equipment.
Below, for canopy support most preferred embodiment, the drawing of accompanying drawing is described as follows: Fig. 1 replaces canopy supporting structure schematic diagram for hydraulic pressure in conjunction with hydraulic pressure.Each sequence number is among the figure: back timber 1, curb girder 2, connecting rod 3, face guard 4, column boots 5, hanging ring 6, circular orbit beam 7, roller 8, balance jack 9, wall supporting jack 10, column 11.
Fig. 2 replaces canopy rack arrangement mode schematic diagram for hydraulic pressure.I is a metallic supports in galleries among the figure, and II is that hydraulic pressure replaces the canopy support, and III is to move the hydraulic pressure of frame state for the canopy support.Sequence number 7 is the circular orbit beam, and 8 is roller.
By hydraulic pressure shown in Figure 2 be: beyond the face end outlet for canopy rack arrangement mode, along advance of the face direction, center to center distance with metallic supports in galleries is arranged the 15-30 frame forward, be the coexistence Support that hydraulic pressure replaces canopy support II and metallic supports in galleries I the last period, one section Support that is the hydraulic pressure of no metallic supports in galleries I for canopy support II, back, each hydraulic pressure is being hung the public circular orbit beam 7 of each frame jointly for the canopy support.
