Abstract
The invention relates to a machine leading support. A support beam is hinge with the top of revolving arm of drill machine; the top part and the support beam are hinged with the lifting connecting rods near the hinge point; another ends of said two lifting connecting rods are hinged; said hinge points are above the revolving arm and the support beam; a lifting hydraulic cylinder is hinged between the hinge point and the revolving arm; the front end of support beam is hinged with a shield beam; the parts of support and shield beam that near the hinge point are hinged with support beam connecting rods; another ends of said two support beam connecting rods are hinged; the hinge points are under the support and shield beam; and the hinge points of said two support beam connecting rods and the support beams are hinged with support beam hydraulic cylinder. The invention can save time, improve efficiency, improve the safety, and simplify the operation.
Description
Technical field:
The present invention relates to machine-carried forepoling device, is at supporting a kind of equipment that empty top zone temporary lining is provided for roadway opening under the coal mine on the fully-mechanized digging machine.
Background technology:
At present during the China's coal-mine roadway opening, its empty top zone adopts many forestopes (steel pipe or square steel) to be suspended on along roadway direction and visits on the top board to empty top zone, and top board is played support action, prevents that the top board roof fall from causing personal injury accidents.Moving forestope during work must manually take off it from top board, suspension ring are taken off be installed on the next anchor pole, and this supporting has following shortcoming: 1. forestope does not have setting load to the supporting of empty top zone, and security reliability is poor; 2. forestope is that point contacts with top board, can not the empty top zone top board effectively be protected; 3. complicated operating process, it moves armrest work industry, and the supporting activity duration is long, has reduced the excavation operation time.
Summary of the invention:
The purpose of this invention is to provide a kind of machine-carried forepoling device, solve the existing shortcoming of using when present coal mine roadway is opened up of interim forestope, can carry out safety, reliable, quick supporting empty top zone.
The objective of the invention is to realize as follows: utilize fully-mechanized digging machine to be main body, install by hydraulic cylinder on its top is the roof timbering device of power.Concrete scheme is: at the hinged brace summer in fully-mechanized digging machine revoliving arm top, the hinged beam connecting rod that rises of close hinge point place difference on fully-mechanized digging machine revoliving arm top and brace summer, the other end of two liters of beam connecting rods is hinged, hinge point is in fully-mechanized digging machine revoliving arm and brace summer top, the hinged beam hydraulic cylinder that rises between the pin joint of two liters of beam connecting rods and fully-mechanized digging machine revoliving arm; The hinged caving shield of brace summer front end, the hinged strutbeam connecting rod of close hinge point place difference on brace summer and caving shield, the other end of two strutbeam connecting rods is hinged, and hinge point is in brace summer and caving shield bottom, hinged strutbeam hydraulic cylinder between the pin joint of two strutbeam connecting rods and brace summer.In fully-mechanized digging machine when work,, caving shield and brace summer are folded position rising under the drive of beam hydraulic cylinder and strutbeam hydraulic cylinder; After finishing, the fully-mechanized digging machine cut is retracted into the supporting district, rise beam connecting rod and strutbeam connecting rod with rising the drive of beam hydraulic cylinder and strutbeam hydraulic cylinder, and then drive brace summer, caving shield swing, after brace summer arrives proper height, caving shield is contacted fully with top board, realize purpose roof timbering.
Caving shield is whole face-type structural, is convenient to contact with top board face formula.
This device is installed on the fully-mechanized digging machine, advances with fully-mechanized digging machine, does not need artificial moving, and saves manpower, shortens non-cutting time, improves Homes Using TV, can improve the roadway opening drilling depth greatly; During supporting roof caving shield is risen, give the top board setting load, effectively top board is carried out supporting, improved security reliability greatly by hydraulic cylinder; Adopt whole caving shield design, caving shield is that face contacts with top board, and the supporting area is big, can carry out supporting to empty top zone effectively; Adopt the fully-mechanized digging machine HYDRAULIC CONTROL SYSTEM, driving can carry out effective support to empty top zone after finishing, and supporting is timely; Adopt hydraulic control during temporary lining,, reduced the generation of personal accident accident in the work of supporting district; Simple to operate, alleviated labor strength greatly, reduced site operation personnel's quantity, improved work efficiency.
Description of drawings:
Accompanying drawing is the structural representation of machine-carried forepoling device of the present invention.
The specific embodiment:
With reference to accompanying drawing, this machine-carried forepoling device by brace summer 5, caving shield 7, rise beam hydraulic cylinder 2, strutbeam hydraulic cylinder 4, rise beam connecting rod 3 and strutbeam connecting rod 6 constitutes.Lean on the hinged brace summer 5 of pin at fully-mechanized digging machine 1 revoliving arm top, the hinged beam connecting rod 3 that rises of close hinge point place difference on fully-mechanized digging machine 1 revoliving arm top and brace summer 5, the other end of two liters of beam connecting rods 3 is hinged, hinge point is in fully-mechanized digging machine 1 revoliving arm and brace summer 5 tops, the hinged beam hydraulic cylinder 2 that rises between the pin joint of two liters of beam connecting rods 3 and fully-mechanized digging machine 1 revoliving arm; Brace summer 5 front ends are by the hinged caving shield 7 of pin, caving shield 7 is whole face-type structural, the hinged strutbeam connecting rod 6 of close hinge point place difference on brace summer 5 and caving shield 7, the other end of two strutbeam connecting rods 6 is hinged, hinge point is in brace summer 5 and caving shield 7 bottoms, hinged strutbeam hydraulic cylinder 4 between the pin joint of two strutbeam connecting rods 6 and brace summer 5.During fully-mechanized digging machine 1 work, rise beam hydraulic cylinder 2 and strutbeam hydraulic cylinder 4 and be contraction state, this moment, caving shield 7 was folded position with brace summer 5.After cut is finished, be retracted into the supporting district, operation control valve is given and is risen beam hydraulic cylinder 2 and strutbeam hydraulic cylinder 4 feed flows, rising beam hydraulic cylinder 2 and strutbeam hydraulic cylinder 4 piston rods stretches out, brace summer 5 and caving shield 7 rise, and caving shield 7 is contacted fully with top board, reach the purpose to roof timbering.
