Abstract
The utility model is specially before one moves frame and protects ejection device temporarily, solves existing frame space-time top of moving to producing the problem burying accident potential.Protect ejection device before moving frame temporarily, comprise the supporting seat that is fixed on elevating conveyor base and be arranged between face end support and individual prop protect back timber, supporting seat top is fixed with protects top base, protect top base and protect between back timber and be provided with the hydraulic jack hinged with both, protect the connecting rod that the hinged one end of back timber left end is hinged with it, the other end and the face end support of connecting rod are hinged, protect back timber left end upper surface and are provided with piston shoes.The utility model ensure that fortune is smooth and easy along advance support procedure connection, produces and provides sound assurance, and save a dead lift monomer hinged working time for raw coal, easy for operation.
Description
Technical field
The utility model relates to colliery with protecting ejection device, is specially before one moves frame and protects ejection device temporarily.
Background technology
Monomer hinged forbidding withdraws in advance, carry out before must preparing pull end head bracket after elevating conveyor is passed, the reach of termination advance support, install and should return machine feed at the saturating rib of coal mining machine cut, push away handpiece of scraper conveyer, face end support moved frame and completed and can carry out after reaching setting load, termination advance support monomer, hinged forbidding withdraw in advance, must within coal-winning machine head 30m from the front end time carry out, monomer, hinged withdraw after as roof cracking, must timely complement monomer point post.
Before moving face end support, when removing first row hydraulic prop, the empty top of first row distance, to constructor's inherently safe with certain danger, causes thus and connects sequence anxiety, bury accident potential to production.
Summary of the invention
The utility model, in order to solve existing frame space-time top of moving to producing the problem burying accident potential, providing before one moves frame and protecting ejection device temporarily.
The utility model adopts following technical scheme to realize: protect ejection device before moving frame temporarily, comprise the supporting seat that is fixed on elevating conveyor base and be arranged between face end support and individual prop protect back timber, supporting seat top is fixed with protects top base, protect top base and protect between back timber and be provided with the hydraulic jack hinged with both, protect the connecting rod that the hinged one end of back timber left end is hinged with it, the other end and the face end support of connecting rod are hinged, protect back timber left end upper surface and are provided with piston shoes.
During operation, elevating conveyor base is utilized to do removable support, carry out effective temporary lining by hydraulic jack to top board, the setting of piston shoes, for reducing the resistance with top board in moving process, overcomes existing frame space-time top of moving to producing the problem burying accident potential.
The utility model reasonable in design is reliable, move with elevating conveyor base, hydraulic mechanism is steady, supporting intensity is large, advance support is carried out in crossheading coal cutting roadway, T-shaped is become to support after stretching, recycle, ensure that fortune is smooth and easy along advance support procedure connection, produce for raw coal and provide sound assurance, and can with permanent support with the use of, far can control it to take a step, from moving, to save the working time that a dead lift monomer is hinged, easy for operation, safe and reliable, have install simple, safety factor is high and protect the larger advantage of top area.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-elevating conveyor base, 2-supporting seat, 3-face end support, 4-individual prop, 5-protects back timber, and 6-protects top base, 7-hydraulic jack, 8-connecting rod.
Detailed description of the invention
Protect ejection device before moving frame temporarily, comprise the supporting seat 2 that is fixed on elevating conveyor base 1 and be arranged between face end support 3 and individual prop 4 protect back timber 5, supporting seat 2 top is fixed with protects top base 6, protect top base 6 and protect between back timber 5 and be provided with the hydraulic jack 7 hinged with both, protect the connecting rod 8 that the hinged one end of back timber 5 left end is hinged with it, the other end and the face end support 3 of connecting rod 8 are hinged, protect back timber 5 left end upper surface and are provided with piston shoes.
In specific implementation process, protect top base 6 welded steel plate that three block length 2500mm × wide 2500 mm × thick 25mm is thick to form, protect top base 6 to be connected with hydraulic jack 7 φ 40mm pin, hydraulic jack 7 setting load is more than 100KN, protect back timber 5 adopt the 12# mining i beam of long 1800mm × wide 120 mm × thick 115mm be transformed into seal type annular i iron protect top, connecting rod adopts the steel plate of long 1050mm × wide 90 mm × thick 30mm to make.
