Abstract
The utility model discloses an end bracket with three frames of one set, wherein the end bracket comprises a main frame and two auxiliary frames respectively arranged at two sides of the main frame along the longitudinal direction; each of the main frame and the two auxiliary frames is composed of a base, a top beam, an upright post arranged between the base and the top beam, a screening beam articulated at the rear end of the top beam and a connecting rod mechanism articulated between the lower end of the screening beam and the base; front ends of the bases of the two auxiliary frames are respectively articulated with a front dragging base of the main frame through a push jack; two sets of adjustable frame jacks extending towards two sides are horizontally articulated in the middle part of the top beam of the main frame front and back; piston rods of the two adjustable frame jacks are respectively articulated with corresponding top beams of the auxiliary frames; and a bottom adjusting jack for adjusting the distance between the main frame and the auxiliary frame is installed at the rear parts of the bases of the two auxiliary frames. The end bracket disclosed by the utility model is specially used for supporting the end of a heading, so that the purposes of increasing starting rate of equipment and enhancing propelling speed of a working surface are achieved.
Description
Technical field
The utility model relates to down-hole fully-mechanized mining working faces end head support, especially relates to three one group of face end supports.
Background technology
Adopt technological development along with combining under the coal mine, also increasingly high to the per unit area yield requirement of fully-mechanized mining working, realize the mechanization of termination operation, be the key that reduces the heavy manual labor of workman, reduction accident rate, raising face propulsion speed, realizes high-yield and high-efficiency.Fully-mechanized mining working also exists an influence and restriction to combine the key factor adopt the benefit performance after having solved each link coordinative composition of equipments of force piece, coal-winning machine, conveyer and transition bracket, that is: to the problem of gallery end support.If it is bad that this problem solves, with the raising of restriction fully-mechanized mining working utilization rate of equipment and installations and efficient.
Summary of the invention
The utility model purpose is to provide a kind of three one group of face end supports that are exclusively used in the gallery end support.
For realizing above-mentioned purpose, the utility model is taked following technical proposals:
Described three one group of face end supports of the utility model comprise body frame and longitudinally are separately positioned on two subframes of said body frame both sides; Said body frame and two subframes by base, back timber, be arranged on column between base and the back timber, be hinged on the caving shield of top beam rear end, the linkage that is articulated between caving shield lower end and the base is formed; Said two subframe front end of base are respectively through dragging seat to be hinged before passing jack and the body frame; Be hinged with two groups of two accent frame jack that extend to both sides before and after the body frame back timber middle part, said two transfer the piston rod of frame jack to be hinged with corresponding subframe back timber respectively; The rear portion of two subframe bases is equipped with the distance between end accent jack adjustment body frame and the subframe.
Said body frame back timber and two subframe back timbers, body frame base and subframe base are the two joint structures that are articulated as one.
In the body frame bottom tub, be provided with elevating conveyor.
The utility model advantage is to be exclusively used in the supporting of gallery termination, the purpose of improve equipment operation rate to reach, accelerating face propulsion speed.When body frame and elevating conveyor reach, handling the body frame column, make body frame break away from top board a little, is fulcrum with two subframes, passes jack and stretches out, body frame and elevating conveyor reach.Handle the body frame column, make the body frame back timber prop up top board, and make column reach setting load; During the subframe reach, be fulcrum, handle the subframe column simultaneously, make subframe break away from top board a little, pass the jack withdrawal, the subframe reach with the body frame.Two subframes can move forward simultaneously, also can move forward respectively.

Fig. 3 is the plan structure sketch map that Fig. 1 conceals caving shield.
The specific embodiment
Like Fig. 1,2, shown in 3, described three one group of face end supports of the utility model comprise body frame and longitudinally are separately positioned on two subframes of said body frame both sides; Said body frame and two subframes by base, back timber, be arranged on column between base and the back timber, be hinged on the caving shield of top beam rear end, the positive quadric chain that is articulated between caving shield lower end and the base is formed; The front end of said two subframe bases 1,2 is respectively through dragging seat 5 to be hinged before passing jack 3,4 and the body frame; Being connected to two groups of two accent frame jack 7,8, said two that extend to both sides before and after the hinge of body frame back timber 6 middle parts transfers the piston rod of frame jack 7,8 to be hinged with corresponding subframe back timber 9,10 respectively; The rear portion of two subframe bases 1,2 is equipped with end accent jack, the distance between adjustment body frame and the subframe.Body frame back timber 6 and two subframe back timbers 9,10, body frame base 11 and subframe base 1,2 are the two joint structures that are articulated as one.In the body frame bottom tub, be provided with elevating conveyor.
Claims (3)
1. three one group of face end supports comprise body frame and longitudinally are separately positioned on two subframes of said body frame both sides; Said body frame and two subframes by base, back timber, be arranged on column between base and the back timber, be hinged on the caving shield of top beam rear end, the linkage that is articulated between caving shield lower end and the base is formed; It is characterized in that: the front end of said two subframe bases (1,2) is respectively through dragging seat (5) to be hinged before passing jack (3,4) and the body frame; Be hinged with two groups of two accent frame jack (7,8) that extend to both sides before and after body frame back timber (6) middle part, said two transfer the piston rod of frame jack (7,8) to be hinged with corresponding subframe back timber (9,10) respectively; The rear portion of two subframe bases (1,2) is equipped with end accent jack (12).
