Abstract
The utility model provides a coal harbor arched supporting shield structure which comprises an outer sleeve and a supporting assembly fixed in the outer sleeve. The outer sleeve comprises a plurality of expansion plates mutually connected together. The expansion plates are connected with the supporting assembly together through a telescopic oil cylinder. The coal harbor arched supporting shield structure solves the problems of roof fall and foothold instability in the process of excavating needling, upper top beams and shed erection operation by manual work. A small hydraulic evacuator is arranged on an equipment platform inside the supporting assembly, and therefore mechanization can be achieved.
Description
Technical field
The utility model belongs to Coal Exploration digging technology apparatus field, especially relates to a kind of coal harbour arch support shield structure.
Background technology
The colliery coal road tunnels used technical equipment except fully-mechanized digging machine, be that hand-holing is blown out, pickaxe excavates, set advance support, upper back timber, manual dig needling, dress leg, etc. construction.So-called advance support is very simple, and two longerons that play protract exactly, or interts into from frame capplce with the pricker plate.There is very large hidden danger in this mode in safety, can not protect the safety of coal miner and equipment when roof fall or the generation of other accidents.
The utility model content
State in order to fill up the blank of colliery coal road driving, realize that the procedure technology of the similar operation except fully-mechanized digging machine is changed.Become meet head on the operation supporting into step back the supporting operation, manual work is the semi-mechanization operation, the utility model proposes a kind of coal harbour arch support shield structure.
The technical scheme that realizes above-mentioned beneficial effect is, a kind of coal harbour arch support shield structure comprises overcoat, is fixed on the supporting component of overcoat inside, described overcoat comprises a plurality of expansion plates that interconnect, and expansion plate connects together with supporting component by telescopic oil cylinder.
Described supporting component comprises joist, and the joist bottom is connected with the leg oil cylinder, and joist inside is fixed with longeron, and the longeron both sides are connected with Width adjustment cylinder, and Width adjustment cylinder links together longeron and joist.
Also be connected with apron plate at the overcoat front end, apron plate links together by propelling cylinder and overcoat.
On longeron, also be fixed with equipment platform.
The utility model in order to solve the incomplete problem that the coal breakage roof fall occurs easily of advance support, adopts the apron plate on hydraulically extensible oil cylinder pushing expansion plate top to stretch out forward when artificial driving, realizes preferably advance support, stops roof fall.Solve manually meet head on to excavate needling, on the roof fall that faces of back timber, the operation of frame canopy and the problem of standpoint shakiness, adopt the equipment platform in the inside of supporting component to assemble small type hydraulic excavator, realize mechanization.In order to solve this novel problem of advancing, after apron plate stretched out, the preparation movable part of overcoat advanced under propelling cylinder promotes with all the other each ones and supporting component, and so operation is until all be advancing to the position.Behind this novel segment distance that advances, its afterbody expansion plate is extracted out from the capplce top of supporting, for next canopy is propped working space in advance.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the present utility model;
Fig. 2 is that the A-A of Fig. 1 embodiment is to structural representation;
Among the figure, 1, overcoat; 11, expansion plate; 2, supporting component; 21, joist; 22, leg oil cylinder; 23, Width adjustment cylinder; 3, telescopic oil cylinder; 4, apron plate; 5, propelling cylinder; 6, equipment platform.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
In conjunction with Fig. 1, a kind of embodiment of the present utility model.A kind of coal harbour arch support shield structure comprises overcoat 1, is fixed on the supporting component 2 of overcoat inside, and described overcoat comprises a plurality of expansion plates that interconnect 11, and expansion plate connects together with supporting component by telescopic oil cylinder 3.In the present embodiment, described supporting component comprises joist 21, and the joist bottom is connected with leg oil cylinder 22, and joist inside is fixed with longeron, and the longeron both sides are connected with Width adjustment cylinder 23, and Width adjustment cylinder links together longeron and joist.Also be connected with apron plate 4 at the overcoat front end, apron plate links together by propelling cylinder 5 and overcoat.On longeron, also be fixed with equipment platform 6.
Excavate in advance at the operation field tunneling direction that 3-5 rice is long, basal area is greater than the installing space of this Novel transverse cross section minimum area.Then with upper coat part at ground-mounted Zhi Dingqi, refill inner support section.The mode that adopts hydraulic drive and expansion plate to cooperate, realize that advance support advance support plate stretches out preferably after, the preparation movable part of overcoat advances for being supported under the hydraulic drive with all the other each ones and inner sleeve, operation like this is until all be advancing to the position.The working space of propping in advance at the afterbody backplate sets up new capplce.Width adjustment cylinder of the present utility model is adjusted the width that overcoat is protected according to the width of actual coal harbour, guarantees the scope of application of the present utility model.
The utility model promotes colliery coal road driving safety.The operating type that props up after the pick before adopting has increased the driving continuity.Alleviate labor strength.Improve work efficiency.
The above; be better case study on implementation of the present utility model; be not that the utility model is imposed any restrictions; every any simple modification, change and equivalent structure of above embodiment being done according to the utility model technical spirit changes, and all still belongs in the protection domain of technical solutions of the utility model.
