Abstract
The U-shaped steel bracket of a kind of mine, comprise left pillar and right pillar, the top of left pillar is connected by U-shaped back timber with the top of right pillar, the bottom of left pillar connects square left base, and the bottom of right pillar connects square right base, and the lower central of square left base is provided with left spine, the lower central of square right base is provided with right spine, the utility model structure is simple, and adjustable length, can be applicable to multiple tunnel.
Description
Technical field
The invention belongs to mining equipment field, particularly the U-shaped steel bracket of a kind of mine.
Background technology
Tunnel safety under mine is the most important thing of mine safety, in order to ensure tunnel safety, need to support protection, existing supporting comprises top board and support etc., support is generally the u shape support adopting geomery fixing, and its length can not adjust, and can not meet the needs in different tunnel, have some can adjust length, its underpart fixed form is not good enough.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide the U-shaped steel bracket of a kind of mine, structure is simple, and adjustable length, can be applicable to multiple tunnel.
To achieve these goals, the technical solution used in the present invention is:
The U-shaped steel bracket of a kind of mine, comprise left pillar 1 and right pillar 2, the top of left pillar 1 is connected by U-shaped back timber 7 with the top of right pillar 2, the bottom of left pillar 1 connects square left base 3, the bottom of right pillar 2 connects square right base 4, the lower central of square left base 3 is provided with left spine 5, and the lower central of square right base 4 is provided with right spine 6.
Described left pillar 1, right pillar 2 and U-shaped back timber 7 are stretching structure.
All there is the oblique jack for inserting inclined support bar the top of described square left base 3 and square right base 4.
Compared with prior art, the invention has the beneficial effects as follows:
1, according to the tunnel situation of reality, size adjustable, is applicable to different tunnel;
2, pillar can go deep into bottom surface, good fixing effect;
3, base can install bearing diagonal, promote support capacity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Embodiments of the present invention are described in detail below in conjunction with drawings and Examples.
As shown in Figure 1, the U-shaped steel bracket of a kind of mine, comprises left pillar 1 and right pillar 2, and the top of left pillar 1 is connected by U-shaped back timber 7 with the top of right pillar 2, and left pillar 1, right pillar 2 and U-shaped back timber 7 are stretching structure.The bottom of left pillar 1 connects square left base 3, and the bottom of right pillar 2 connects square right base 4, and the lower central of square left base 3 is provided with left spine 5, and the lower central of square right base 4 is provided with right spine 6.All there is the oblique jack for inserting inclined support bar the top of square left base 3 and square right base 4.
Use the present invention, the size of whole support can be adjusted according to the shape specification in tunnel, size adjusting well after, left spine 5 and right spine 6 are hammered into underground, and then utilize rivet to be fixed on the ground by base, fixed effect is good.Meanwhile, in order to strengthening supporting, bearing diagonal can be inserted in the oblique jack above square left base 3 and square right base 4, the top of bearing diagonal can be pushed up on support in wall or adjacent.
