Abstract
The utility model relates to a combination bracket which is provided with a suspension mechanism and a guiding travelling beam. The combination bracket is a movable bracket which is used for coal mine down-well mining operating surface. The combination bracket is composed of the suspension mechanism, an upper beam, a guiding movable beam, a movable hydraulic cylinder and a support. Each bracket is connected with each other through the suspension mechanism and the guiding movable beam. Namely the generation of horizontal and vertical displacement of adjacent upper beams can be satisfied. The load of movable bracket is bear by the adjacent frames through the suspension mechanism and the guiding movable beam. In the using of bracket, the bracket connection of whole operating surface becomes a whole through the suspension mechanism and the guiding movable beam. The combination bracket has the advantages of high stability, quick motion and strong adaptability. The combination bracket is suitable for the blast mining surface operation with large inclination angle and irregularity and machine mining operating surface operation.
Description
Technical field
The utility model relates to a kind of sectional shelf-unit with hitch and guiding trave lling girder, belongs to underground mining support apparatus technical field.
Background technology
At present, the existing sectional shelf-unit of domestic colliery underground mining work plane all exists steadily, easily not produce phenomenons such as frame, adjacent stent interfere with each other all around when mobile.This support high inclination-angle and the irregular work plane of top board can not normally be used.
Technical scheme
The purpose of this utility model provides band hitch that uses in the work plane of a kind of suitable high inclination-angle, out-of-flatness top board and the sectional shelf-unit that leads trave lling girder, it is by hanging the guiding that connects and lead trave lling girder between back timber, can even running when support is moved, even the phenomenon of interfering mutually between support can not take place in large inclination working surface yet.
The purpose of this utility model is to realize like this, back timber is a rectangle, the bottom is provided with a gathering sill at least, before and after respectively being provided with, its both sides all are provided with a hitch fairlead and a back-moving spring on two hitch guide pegs, every hitch guide peg, the hitch fairlead is provided with chaining outward and links to each other with the chaining of adjacent frame, guiding is provided with a guide rail consistent with the gathering sill direction of back timber bottom setting on the trave lling girder at least and is embedded in the gathering sill, the guiding trave lling girder is connected with mobile hydraulic cylinder with back timber, and four hydraulic props connected vertically are equipped with in the back timber lower end.
The utility model has the advantages that: the chaining of hitch couples together adjacent back timber, trave lling girder has guide peg and guide rail, the all around swing when being moved, support does not take place, globality is strong during use, compliance strong, stability is high, have advantages such as preventing down frame, move steadily, phase mutually noninterfere when support moves, safety are good, suitable big gun is adopted and machine mining face.
Description of drawings
Fig. 1 is a front view of the present utility model,
Fig. 2 is a right view of the present utility model,
Fig. 3 is a connection diagram of the present utility model.
The specific embodiment
With reference to the accompanying drawings 1, Fig. 2, Fig. 3 in conjunction with present embodiment to being described further: a kind of with hitch and the guiding trave lling girder sectional shelf-unit comprise hitch fairlead (1), chaining (2), back-moving spring (3), hitch guide peg (4), mobile hydraulic cylinder (5), guiding trave lling girder (6), back timber (7), hydraulic prop (8), adapter sleeve (9) is characterized in that: back timber (7) is a rectangle, the bottom is provided with a gathering sill at least, two hitch guide pegs (4) before and after its both sides respectively are provided with, all be provided with a hitch fairlead (1) and back-moving spring (3) on the every hitch guide peg (4), being provided with chaining (2) outside the hitch fairlead (1) links to each other with the chaining of adjacent frame, a guide rail consistent with the gathering sill direction of back timber (7) bottom setting is set on guiding trave lling girder (6) at least and is embedded in the gathering sill, guiding trave lling girder (6) is connected with mobile hydraulic cylinder (5) with back timber (7), four hydraulic props connected vertically (8) are equipped with in back timber (7) lower end, and adjacent two guiding trave lling girders (6) connect with adapter sleeve (9).
During support work, supporting back timber (7) by four hydraulic props (8) that are installed in below the back timber, play the support action of stope, when support moves, at first to the loculus fluid injection of hydraulic prop (8), hydraulic prop (8) is mentioned leave base plate, back timber (7) breaks away from top board simultaneously, and chaining (2) and guiding trave lling girder (6) carrying back timber (7) and the slough above the back timber (7) by hitch, to the big chamber fluid injection of mobile hydraulic cylinder (5), because the big chamber end of mobile hydraulic cylinder (5) is connected with back timber (7), the loculus end is connected with guiding trave lling girder (6), and the guide rail on the guiding trave lling girder (6) is installed in the gathering sill of back timber (7), back timber this moment (7) steadily moves forward the stroke of a mobile hydraulic cylinder (5) along the guide rail above the guiding trave lling girder 6, again to the big chamber fluid injection of hydraulic prop (8), make support return to support state just, after the back timber (7) of finishing each frame moves again simultaneously to each frame mobile hydraulic cylinder (8) loculus fluid injection, because every guiding trave lling girder (6) connects into an integral body, so guiding trave lling girder of entire working surface, under the effect of the mobile hydraulic cylinder of each frame, move forward one with the back timber mobile phase with stroke, back timber moves mutually with the guiding trave lling girder, and the support that has formed a whole set of work plane moves along the stepping of work plane vertical direction.
Claims (3)
1, a kind of sectional shelf-unit with hitch and guiding trave lling girder, by the hitch fairlead, chaining, back-moving spring, the hitch guide peg, mobile hydraulic cylinder, the guiding trave lling girder, back timber, hydraulic prop, adapter sleeve constitutes, it is characterized in that: back timber is a rectangle, the bottom is provided with a gathering sill at least, two hitch guide pegs before and after its both sides respectively are provided with, all be provided with a hitch fairlead and a back-moving spring on the every hitch guide peg, the hitch fairlead is provided with chaining outward, guiding is provided with the consistent guide rail of gathering sill direction that is provided with the back timber bottom on the trave lling girder at least and is embedded in the gathering sill, and the trave lling girder that leads is connected with mobile hydraulic cylinder with back timber.
2, according to the said a kind of sectional shelf-unit with hitch and guiding trave lling girder of claim 1, it is characterized in that: hitch is made up of hitch fairlead, chaining, back-moving spring, hitch guide peg.
