The front support is connected with a front support top beam and a support base seat in a hinged mode through a front support front stand column and a front support back stand column, and a front support upper connecting bar is connected with a front support front connecting bar and a front support back connecting bar and then is connected with the front support top beam and the front support base seat in a hinged mode so that the four-bar linkage of the front support is formed and arranged between the front support front stand column and the front support back stand column. A back support upper connecting bar is connected with a back support front connecting bar and a back support back connecting bar and then is connected with the tail portion of a back support top beam and the tail portion of a back support base seat so that the four-bar linkage of the back support is formed and is connected between the top beam and the base seat in a hinged mode. The back portion of a push bar is connected with the middle portion of the back support base seat. A back support front beam and the back support top beam are connected in a hinged mode. The end support of the fully-mechanized coal mining face has the advantages of being reasonable in structure, convenient to move, high in supporting force, large in provided working space and capable of satisfying the requirements of coalmine production.
Description
Technical field
The utility model relates to mechanical coal mining operation laneway support bracket under a kind of coal mine, particularly a kind of Full-mechanized mining working face ended support 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 large, 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 large, support force is not enough, translational speed is low, the working environment poor stability.Present face end support, number be CN201314239Y " end support for roadway caving " such as patent announcement, patent announcement number is " self-moving type end bracket " 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 purpose of this utility model provides a kind of Full-mechanized mining working face ended support, solves the problem that the fully-mechanized mining working faces end head supporting exists.
The purpose of this utility model is achieved in that and comprises side arm and after-frame, by back timber, base, column, quadric chain, advancing 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, 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 by side arm front column and the hinged side arm back timber of side arm rear column and side arm base, after connecting rod and side arm front rod and side arm back link connect on the side arm and side arm back timber and side arm base hinged, form quadric chain, be installed between side arm front column and the side arm rear column.Connecting rod connects rear and after-frame back timber afterbody and the hinged composition quadric chain of after-frame base afterbody with after-frame front rod and after-frame back link on the after-frame, 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.Advancing jack is connected with connecting rod, the middle part between hinged and side arm base and the after-frame base.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.
The utility model has the advantages that: rational in infrastructure, move that frame is convenient, support force working space high, that provide is large, can satisfy the coal production requirement.
Description of drawings:
Accompanying drawing 1 is structure chart of the present utility model
Accompanying drawing 2 is base vertical views of Fig. 1
