Abstract
The invention provides an end head support frame of a fully mechanized mining face. The end head support frame is mainly characterized in that a front frame and a back frame are in one group, a four-bar linkage mechanism of the front frame is arranged between upright posts of the front frame, and a four-bar linkage mechanism of a back frame is arranged at the back part of the back frame. The front frame is hinged with a front frame top beam and a front frame base through a front frame front upright post and a front frame back upright post, a front frame upper linkage bar is connected with a front frame front linkage bar, and the front frame back linkage bar and is then hinged with a front frame top beam and a front frame base, the four-bar linkage mechanism is formed and is arranged between the front frame front upright post and the front frame back upright post; and a back frame upper linkage bar is connected with a back frame front linkage bar and a back frame back linkage bar and is then hinged with the tail part of a back frame top beam and the tail part of a back frame base, and the four-bar linkage mechanism is formed and is hinged between the top beam and the base. The back part of a push bar is hinged with the middle part of the back frame base, and a back frame front beam is hinged with the back frame top beam. The end head support frame has the advantages that the structure is reasonable, the frame moving is convenient, the support force is high, the provided operation space is large, and the production requirement of the coal mine can be met.
Description
Technical field
The present invention relates under a kind of coal mine the mechanical coal mining operation and use the roadway support support, particularly a kind of fully-mechanized mining working faces end head support that is used for the fully-mechanized mining working faces end head supporting.
Background technology
In coal mining, the end regions of fully-mechanized mining working is the intersectional region of work plane and headentry, and roof pressure is big, and the ore deposit is pressed complicated, and apparatus arrangement is many, and working space is narrow.All the time, all be the mode that adopts the intensive supporting of individual prop multiple spot, its supporting is numerous and diverse, operating personnel's labour intensity is big, support force is not enough, translational speed is low, the working environment poor stability.Present face end support; Like patent announcement number is CN201314239Y " tunnel Caving Coal face end support "; Patent announcement number is " automatic moving type face end support " and " fully mechanized caving face along-track end bracket " that patent publication No. is CN101315031A of CN201288579Y; To thin coal bed fully-mechanized mining operation working face termination, fully mechanized caving coal operation working face termination, the scheme of effective solution end support has been proposed all.But the problem of adopting related fully-mechanized mining working faces end head supporting is combined in the coal seam between thin coal bed fully-mechanized mining and the fully mechanized caving coal, does not also have feasible measure and scheme.
Summary of the invention
The objective of the invention is provides a kind of fully-mechanized mining working faces end head support to the deficiency that exists in the above-mentioned technology, can solve the problem that the fully-mechanized mining working faces end head supporting exists.Not only support force is high, and working space is big.
The objective of the invention is to realize like this: comprise side arm and after-frame; By back timber, base, column, quadric chain, passing jack, connecting rod; It is characterized in that: side arm and after-frame are one group; Described side arm and after-frame are the four post support shield type hydraulic supports, and the quadric chain of side arm is installed between the column of side arm, and the quadric chain of after-frame is installed in the rear portion of after-frame.Side arm is through side arm front column and hinged side arm back timber of side arm rear column and side arm base; It is hinged that connecting rod is connected back and side arm back timber and side arm base on the side arm with side arm front rod and side arm back link; Form quadric chain, be installed between side arm front column and the side arm rear column.Connecting rod is connected back and after-frame back timber afterbody and the hinged composition quadric chain of after-frame base afterbody on the after-frame with after-frame front rod and after-frame back link, and quadric chain is articulated between back timber and the base.Hinged after-frame base middle part, push rod rear portion.After-frame front-axle beam and after-frame back timber are hinged.Pass jack and be connected, the middle part between hinged and side arm base and the after-frame base with connecting rod.Connecting rod one end is articulated in the front portion of side arm base, and the other end is used for the transporter in hinged the place ahead.
Advantage of the present invention is: rational in infrastructure, move that frame is convenient, support force working space high, that provide is big, can satisfy the Coal Production requirement.
Description of drawings:
Accompanying drawing 1 is a structure chart of the present invention
Accompanying drawing 2 is base vertical views of Fig. 1
Label is represented as follows among the figure: 1, side arm; 2, after-frame; 3, side arm back timber; 4, side arm front column; 5, connecting rod on the side arm; 6, side arm front rod; 7, side arm back link; 8, side arm base; 9, side arm rear column; 10, push rod; 11, after-frame front-axle beam; 12, after-frame back timber; 13, after-frame front column; 14, after-frame base; 15, after-frame rear column; 16, connecting rod on the after-frame; 17, after-frame front rod; 18, after-frame back link; 19, connecting rod; 20, pass jack.
The practical implementation method:
Below in conjunction with accompanying drawing present embodiment is further specified:
Can be known that by Fig. 1-2 side arm 1 is formed one group with after-frame 2, side arm 1 is through side arm front column 4 and side arm rear column 9 hinged side arm back timbers 3 and side arm base 8; Connecting rod 5 is connected back and side arm back timber 3 and side arm base 8 hinged composition quadric chains on the side arm with side arm front rod 6 and side arm back link 7, is installed between side arm front column 4 and the side arm rear column 9; The hinged side arm base of connecting rod 19 1 ends 8 front portions, the transporter in the other end and the place ahead is hinged, and after-frame 2 is through after-frame front column 13 and after-frame rear column 15 hinged after-frame back timbers 12 and after-frame base 14; Connecting rod 16 is connected back and after-frame back timber 12 afterbodys and the hinged composition quadric chain of after-frame base 14 afterbodys on the after-frame with after-frame front rod 17 and after-frame back link 18.Push rod 10 is connected with passing jack 20, passes the hinged side arm base of jack 20 front ends 8 middle parts, hinged after-frame base 14 middle parts, push rod 10 rear portions.After-frame front-axle beam 11 is hinged with after-frame back timber 12.
Job step of the present invention: arrange side arm 1 and after-frame 2 at fully-mechanized mining working faces end head, front column and rear column elongate support are between top board and top board.When moving frame; Side arm front column 4 on the side arm 1 and 9 withdrawals of side arm rear column; The cylinder post of passing jack 20 stretches out; With after-frame 2 is fulcrum, promotes side arm base 8 and makes side arm 1 reach the operating position, and 9 elongations make side arm back timber 3 top boards and side arm base 8 be pressed onto base plate to side arm front column 4 with the side arm rear column.After-frame front column 13 on the after- frame 2 and 15 withdrawals of after-frame rear column; Pass the cylinder post withdrawal of jack 20; With side arm 1 is fulcrum; Pulling after-frame base 14 makes after-frame 2 reach the operating position, and 15 elongations make after-frame back timber 12 top boards and after-frame base 14 be pressed onto base plate to after-frame front column 13 with the after-frame rear column.
