Abstract
The invention discloses a large-step-pitch along-roof walking single column support set. The large-step-pitch along-roof walking single column support set comprises bases. A plurality of vertical columns are hinged to the bases. A column adjustment jack is connected between each vertical column and the corresponding base. The multiple vertical columns are arranged into a single row and multiple lines or multiple rows and a single line or multiple rows and multiple lines. Column top caps are arranged at the top ends of the vertical columns, oval cambered surfaces making contact with the top ends of the vertical columns are arranged on the lower portions of the column top caps, and anti-slipping cone columns are arranged on the tops of the column top caps. The multiple bases are arranged and hinged to one another. Pull jacks and pull rods are arranged in front of the bases. The large-step-pitch along-roof walking single column support set is stable and flexible, and large supporting height, self-movement and continuous supporting can be achieved.
Description
Technical field
The present invention relates to a kind of colliery tunnel support equipment, relate in particular to a kind of large step pitch along top step type single-column supporting group.
Background technology
At present, Modern Pit roadway support is generally used advance timbering supporting, and for preventing the support repeatedly to top board, advance timbering progressively develops into large step pitch moving manner, and between frame, top board temporary lining adopts extensible canopy and one-level or two, three-stage side protecting supporting substantially.As shown in Figure 1, because of extensible canopy or wall supporting narrower, be difficult to comprehensive supporting, especially, between face end support and advance timbering, there will be larger area non-support district.
For this region back of supporting, part mining area adopts narrow type support, because scrapper conveyor exists upper and lower vibration phenomenon, and the use existence and stability of narrow type support and the problem of flexibility deficiency, therefore, narrow type support now seldom uses.
In prior art, for the maintenance of this region back, most of use individual prop, but the use of individual prop, inefficiency, recruitment is more, does not match with modernization mechanization production speed, has become a key factor that affects the advance of the face.Especially for the supporting in superelevation tunnel, such as 6 meters of high tunnels, because the restriction (being generally no more than 4.5 meters) of monomer height needs to take to beat the modes such as grillage below top board especially, had a strong impact on the production efficiency of work plane.
Summary of the invention
The object of this invention is to provide a kind of stable, large step pitch is along top step type single-column supporting group flexibly.
The object of the invention is to be achieved through the following technical solutions:
Large step pitch of the present invention, along top step type single-column supporting group, comprises base, is hinged with many root posts on described base, is connected with respectively and adjusts post jack between every root post and described base.
As seen from the above technical solution provided by the invention, the large step pitch that the embodiment of the present invention provides is along top step type single-column supporting group, owing to being hinged with many root posts on base, between every root post and base, be connected with respectively and adjust post jack, stable, flexibly, can realize large bearing height, realize from moving and continuous supporting.

Detailed description of the invention
To be described in further detail the embodiment of the present invention below.
Large step pitch of the present invention is along top step type single-column supporting group, its preferably detailed description of the invention be:
Comprise base, on described base, be hinged with many root posts, between every root post and described base, be connected with respectively and adjust post jack.
Described many root posts are arranged to single multiple row or arrange single-row more or arrange multiple row more.
The top of described column is provided with capital cap, and the bottom of described capital cap is provided with the elliptoid cambered surface contacting with described column top, and the top of described capital cap is provided with anti-skidding cone post.
Described base has multiple, between multiple bases, is hinged.
The front portion of described base is provided with to draw to move jack and draw moves bar.
Large step pitch of the present invention is along top step type single-column supporting group, stable, flexibly, can realize large bearing height, realize from moving and continuous supporting.
Principle of the present invention is:
By large magnification upright supports, realize large working resistance, large bearing height;
Be fixed on a base hinged several columns, can reduce floor pressure ratio Air holder, improve Column stability, be convenient to realize in groups and pass;
Hinged capital cap on column, is convenient to column and firmly connects top, strengthens and connects top area;
By the Tiao Zhu mechanism of jack control, controlling separately column can swing, is convenient in the supporting of diverse location point;
Every root post and tune post jack, control separately lifting or swing by hydraulic valve, so that realize local supporting and continuous supporting.
The angle and distance size of adjusting post upper end swing, can realize one or more step pitches that once move forward;
Can be connected with advance timbering base with front carrying out by connecting rod.
Specific embodiment:
As shown in Figure 2, comprise drawing and move jack, draw and move bar, base, column, Tiao Zhu mechanism and adjust post jack, capital cap, column pressing plate, connector and hydraulic control system etc.
Base: according to the size of supporting regional space, determine the width of base; Base adopts the articulated form of a joint or more piece, to adapt to the size of uneven base plate and supporting area; Fixing of column and base, at the bottom of employing pressing plate or post, the form of bearing pin, prevents that column from swinging or rotating, and ensures the stability of supporting group.
Tiao Zhu mechanism: be fixed on the engaging lug on column, and be fixed on the engaging lug on base, connect by jack, form adjusting post swing mechanism.
Pull body: by engaging lug, connecting rod, draw and move jack and connector etc. and form.
Capital cap: as shown in Figure 3 a, 3 b, be cambered surface contact with column column cap, crown is set up defences and slided cone post.
Specific embodiment move frame step:
As shown in Figure 4, be that two step pitches are moved frame circulation from right to left, comprise step:
Original state--first step distance----circulation that second step distance--is moved frame--that the first step is apart from completing.
As shown in Fig. 5 a, 5b, the present invention can be used for the large step pitch advance timbering of auxiliary shoring, supporting less than top board; Can be used between supporting advance timbering and face end support, supporting less than top board; Can be used for 4.5 meters of supportings above, monomer supporting less than or need the top board that Support Resistance is larger; Can be used for supporting should not use hydraulic support, work plane or back that top board unevenness is larger; Have mode flexibly, strong adaptability, supporting intensity is high, weight is light, investment I realizes from moving and the advantage such as continuous supporting.
The above; only for preferably detailed description of the invention of the present invention, but protection scope of the present invention is not limited to this, is anyly familiar with in technical scope that those skilled in the art disclose in the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
