Abstract
An end hydraulic support for supporting the lower end of the coalmine fully mechanized caving face, which is composed of a top beam 1, a column 2, a bed box and a telescopic beam7, and etc, namely, a pedestrian gap bridge 3 with the pedestrian stairs 8 is connected to the both sides of the base part 5 on both sides of the transfer machine. The height of the pedestrian gap bridge 3 is taller than the spillplate of the crossheading transfer machine. The end hydraulic support can automatically move, The utility model has high supporting strength, safety and reliability, small maintenance amount, high efficiency, can effectively maintain the safety exit under the caving face and ensure the safe and convenience getting through of the personnels from the lower safety exit and the bestride transfer machine.
Description
Technical field
The utility model relates to the coal mine fully-mechanized mining working faces end head support apparatus, the end hydraulic support that the supporting of particularly a kind of comprehensive extracting and caving face lower end is used.
Background technology
At present, in process of coal mining, the top board in the integrated caving hydraulic support of the comprehensive extracting and caving face supported face, for the lower end of fully mechanized coal face, promptly with the supporting in following crossheading crosspoint, generally take the intensive supporting of outside injection type hydraulic pillar.Complex manufacturing, labor strength is big, and is low to roof timbering intensity, causes fully mechanized coal face termination top board roof fall accident easily, becomes very big potential safety hazard.Simultaneously, personnel are also dangerous across stage loader in place, emergency exit, fully mechanized coal face termination.
" colliery chief engineer's operating instructions " first volume that the Coal Industry Press publishes in December, 1988 has been put down in writing " D1ZY35 type head face end support " for 682 pages.This face end support is made of back timber, column, base, front-axle beam etc., and about being divided into two, place the stage loader left and right sides respectively, there is the frame of accent jack to connect between two.It is the fully-mechanized mining working faces end head support, not too is fit to fully mechanized coal face, and the personnel that can not solve are by the safety problem of emergency exit under the fully mechanized coal face across stage loader.
Summary of the invention
Existing fully mechanized coal face end support intensity low-security is poor, supporting labour intensity is big, work efficiency is low in order to overcome, across the deficiency of stage loader inconvenience, the utility model provides a kind of supporting intensity height, safety, personnel by the end hydraulic support of emergency exit under the work plane across the stage loader safe ready.
The technical scheme that its technical problem that solves the utility model adopts is:
End hydraulic support is made of back timber, column, base member case, extensible canopy etc.Its base member case adopts the bridge architecture across elevating conveyor, that is: be connected with People's Bank of China in the both sides of two base portion that lay respectively at the elevating conveyor both sides and pass a bridge, and the height that People's Bank of China passes a bridge is higher than the stage loader spillplate, and there is People's Bank of China's ladder the both sides that People's Bank of China passes a bridge.
The technical scheme that its technical problem that solves the utility model adopts can also be:
The People's Bank of China of end hydraulic support passes a bridge and adopts " ∏ " shape.Below the back timber, be provided with the lifting lead with row between the column, the lower end of lifting lead is installed in the fairlead of People's Bank of China on passing a bridge, and can slide up and down.
The beneficial effects of the utility model are:
1. this support strengthens the supporting intensity in crosspoint, fully mechanized coal face termination, safe and reliable stable, safeguard the safety of fully mechanized coal face lower end emergency exit effectively, reach emergency exit, fully mechanized coal face termination standard, prevent the generation of crosspoint, fully mechanized coal face termination roof fall accident.Can adapt to the changeable geological conditions in down-hole, reduce the maintenance workload of worker top board.
2. this support can be realized the migration of stage loader across on elevating conveyor under the hydraulic support stand state.Make staff's warp pass in and out work plane across the stage loader safe ready in the emergency exit down.

Among the figure: 1-back timber, 2-column, 3-People's Bank of China gap bridge, 4-stage loader, 5-base portion, 6-lifting lead, 7-extensible canopy, 8-People's Bank of China ladder
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
In the structure of the utility model end hydraulic support shown in Fig. 1,2, mainly form by back timber 1, column 2, base member case, lifting lead 6, extensible canopy 7.
The base member case of end hydraulic support adopts bridge-type base member case structure, it comprises two base portion 5 that lay respectively at the stage loader both sides, and be connected the People's Bank of China that is " ∏ " shape between the both sides of two base portion 5 and pass a bridge 3, the height of People's Bank of China's gap bridge 3 is higher than the spillplate of stage loader, the middle part of its two side portions also is provided with People's Bank of China's ladder 8, and the formation personnel are across the passage of stage loader 4.The both sides of People's Bank of China's ladder 8 are body structure, are one with base portion 5 welderings.The end face of base member case is a steel plate.This support claims the bridge-type end hydraulic support again.
The back timber 1 of end hydraulic support adopts the back timber of big width, and across stage loader 4, the front end of back timber 1 is equipped with extensible canopy 7.Back timber 1 is hinged with the upper end of column 2, and the lower end of column 2 and the base portion of base member case 5 are hinged.The front end of base portion 5 is hinged by push-and-pull jack and stage loader, realizes moving certainly of end hydraulic support and stage loader.
End hydraulic support has forward and backward two row's columns 2, and there is lifting lead 6 centre of every row's column 2, and the upper end of lifting lead 6 and back timber 1 are fixedly connected, and its lower end places the fairlead that cooperates with it, and fairlead is fixed on the end face of base member case.When the support lifting, lifting lead 6 slides up and down along fairlead, realizes guiding.The support space at column 2 rear portions is arranged in front-seat column 2 front portions and back, gives over to the space of the head of anterior work plane drag conveyor and Background Job face drag conveyor.
The People's Bank of China of end hydraulic support passes a bridge 3 also can be without ∏ shape, and adopts trapezoidal that both sides slightly tilt.
End hydraulic support also can be without lifting lead 6, and adopts other form of structure, as: column and base portion are fixedly connected; Perhaps, the support rear portion increases caving shield and front and rear connecting rods mechanism thereof.
This termination hydraulic support is applicable to the fully mechanized coal face lower end, also can be used for fully-mechanized mining working.
The course of work: with this support according to physical condition is correct install after, be used as power by the emulsion power pack feed flow, according to operation sequence, realize the mobile of end hydraulic support and stage loader.Its operation sequence is: 1. push-jump carrier aircraft: the support stretching, and push-and-pull jack feed flow makes the elevating conveyor reach; 2. push away the anterior drag conveyor head of work plane: fly down jack feed flow; 3. pull end head hydraulic support: column shrinks and reduces support, by the reverse feed flow of push-and-pull jack, and the reach of pull end head hydraulic support, the column feed flow rises the frame roof supporting; 4. draw rear portion drag conveyor head: draw rear portion head jack feed flow.
