Abstract
The U-shaped steel bracket of a kind of mine with bearing diagonal; comprise pillar to be connected with U-shaped back timber; the bottom of pillar connects base; the top of pillar connects footstock; the end face of base is provided with conical lower portion around pillar and supports; the bottom surface of footstock is provided with conical top around pillar and supports; conical lower portion supports and conical top supports the oblique jack be provided with for inserting inclined support bar; the utility model structure is simple; adjustable length; can synergistic protective effect be produced between adjacent stent, 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 with bearing diagonal.
Background technology
Tunnel safety under mine is the most important thing of mine safety, and in order to ensure tunnel safety, need to support protection, existing supporting comprises top board and support etc.General is all that single support uses, and lack coordinating protection, and support is generally the u shape support adopting geomery fixing between adjacent stent; its length can not adjust; 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 with bearing diagonal, can bearing diagonal be set up between adjacent stent, and stent length being adjustable, multiple tunnel can be applicable to.
To achieve these goals, the technical solution used in the present invention is:
The U-shaped steel bracket of a kind of mine with bearing diagonal, comprise pillar 1 to be connected with U-shaped back timber 8, the bottom of pillar 1 connects base 3, the top of pillar 1 connects footstock 5, the end face of base 3 is provided with conical lower portion around pillar 1 and supports 2, the bottom surface of footstock 5 is provided with conical top around pillar 1 and supports 6, conical lower portion support 2 and conical top support the oblique jack be provided with on 6 for inserting inclined support bar 7.
The bottom surface of described base 3 is provided with spine 4.
Described pillar 1, inclined support bar 7 and U-shaped back timber 8 are stretching structure.
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 ground, good fixing effect;
3, install bearing diagonal between footstock and base, each support carries out coordinating protection, promotes support capacity.
Accompanying drawing explanation
Fig. 1 is the connection diagram of the present invention's two supports.
Fig. 2 is the elevation of the independent support 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 depicted in figs. 1 and 2, the U-shaped steel bracket of a kind of mine with bearing diagonal, comprises pillar 1 and is connected with U-shaped back timber 8, and the bottom of pillar 1 connects base 3, and the bottom surface of base 3 is provided with spine 4.The top of pillar 1 connects footstock 5, and U-shaped back timber 8 is connected to the end face of footstock 5.The end face of base 3 is provided with conical lower portion around pillar 1 and supports 2, and the bottom surface of footstock 5 is provided with conical top around pillar 1 and supports 6, conical lower portion support 2 and conical top support the oblique jack be provided with on 6 for inserting inclined support bar 7.Its B-C post 1, inclined support bar 7 and U-shaped back timber 8 are stretching structure.
Use the present invention, the size of whole support can be adjusted according to the shape specification in tunnel, size adjusting well after, spine 4 is hammered into underground, and then utilize rivet to be fixed on the ground by base 3, fixed effect is good.Then, inclined support bar 7 is inserted in oblique jack, realizes the connection of adjacent stent, adjacent stent energy coordinating protection after connecting, thus promote support capacity.
