Abstract
The utility model discloses a support part of a main shaft dangerous arch. The support part of the main shaft dangerous arch comprises a three-core arch, the three-core arch supports the upper portion of the main shaft dangerous arch, and the three-core arch is fixed through plumbing bars. One ends of the plumbing bars are connected with the three-core arch, and the other ends of the plumbing bars are vertically connected with the ground of the main shaft dangerous arch. A first plumbing bar of the plumbing bars is connected with the top of the three-core arch, a second plumbing bar is connected with the left side of the three-core arch, and a third plumbing bar is connected with the right side of the three-core arch. Compared with the prior art, the support part of the main shaft dangerous arch not only does not damage the whole structure of a main shaft, but also can be replaced safely and conveniently, so that collapse caused by interaction between dangerous arch stones and occurring in the whole dangerous arch is prevented, material consumption is reduced greatly, and a large amount of time and cost are saved.
Description
Technical field
The utility model relates to the field of main hole fastening devices, exactly refers to a kind of support component of main hole danger arch.
Background technology
At present, our China exists a lot of mines and colliery to go out of use for various reasons in one's early years, and now because resource scarcity needs again production.But owing to do not produce for many years, main hole loses in maintenance, deflection aggravation under the continuous action of mine pressure, cause top and the projected side wall of main hole of inclined shaft plagioclase serious, thereby cause track to be extruded distortion, so that mine car is substantially impassable, the danger of collapsing is arranged at any time, if produce reluctantly, careless slightly mine car is clipped arch wall and it is drawn is collapsed, and its consequence is hardly imaginable, so full maintenance main hole danger arch is the task of top priority, also be the biggest problem of again producing, be badly in need of improving.
The utility model content
For defects, the technical problem that the utility model solves is to provide a kind of support component of main hole danger arch, both do not destroyed the main hole overall structure, can replace on safe ready ground again, can prevent because of the interaction between danger voussoir head, bring collapsing of whole danger arch, reduced a large amount of material consumptions, saved a large amount of time and expense.
In order to solve above technical problem, the support component of the main hole danger arch that the utility model provides, comprise the three-core bow member, described three-core bow member supports the top of main hole danger arch, described three-core bow member is fixed by plumbing bar, described plumbing bar one end is connected with described three-core bow member, the vertical connection of ground of the other end and main hole danger arch, the first plumbing bar in the described plumbing bar is connected to the top of described three-core bow member, the second plumbing bar is connected to the left side of described three-core bow member, and the 3rd plumbing bar is connected to the right side of described three-core bow member.
Preferably, described plumbing bar is connected with described three-core bow member by welding manner.
Preferably, described plumbing bar is one section light rail.
Preferably, described three-core bow member also is fixed by brace, and described brace one end connects the top of described three-core bow member, and the other end connects the sidewall of main hole danger arch.
Preferably, described brace is one section light rail.
Preferably, the support component of main hole danger arch also comprises cross bar, and described cross bar is fixed the sidewall of main hole danger arch, and the two ends of described cross bar connect respectively the sidewall of main hole danger arch.
Preferably, described cross bar is one section light rail.
Preferably, the top of described three-core bow member is equipped with the anchor net.
Compared with prior art, the support component of the main hole danger arch that the utility model provides has the following advantages: it had not both destroyed the main hole overall structure, can replace on safe ready ground again, can prevent because of the interaction between danger voussoir head, bring collapsing of whole danger arch, reduce a large amount of material consumptions, saved a large amount of time and expense.
Description of drawings
Fig. 1 is the use state diagram of the support component of main hole danger arch among the utility model embodiment.
The specific embodiment
For those skilled in the art can understand technical scheme provided by the utility model better, set forth below in conjunction with specific embodiment.
See also Fig. 1, this figure is the use state diagram of the support component of main hole danger arch among the utility model embodiment.
The support component of the main hole danger arch that present embodiment provides, comprise three-core bow member 1, the top of 1 pair of main hole danger of three-core bow member arch 5 is supported, three-core bow member 1 is fixed by plumbing bar, plumbing bar one end is connected with three-core bow member 1, and vertical connection of ground of the other end and main hole danger arch 5, the first plumbing bar 21 in the plumbing bar is connected to the top of three-core bow member 1, the second plumbing bar 22 is connected to the left side of three-core bow member 1, and the 3rd plumbing bar 23 is connected to the right side of three-core bow member 1.Plumbing bar is connected with three-core bow member 1 by welding manner.Three-core bow member 1 also is fixed by brace 3, and brace 3 one ends connect the top of three-core bow member 1, and the other end connects the sidewall of main hole danger arch 5.The support component of main hole danger arch also comprises cross bar 4, and the sidewall of 4 pairs of main hole danger of cross bar arch 5 is fixed, and the two ends of cross bar 4 connect respectively the sidewall of main hole danger arch 5.
Plumbing bar is one section light rail, and intensity is guaranteed, and is convenient to draw materials; Brace 3 is one section light rail, and intensity is guaranteed, and is convenient to draw materials; Cross bar 4 is one section light rail, and intensity is guaranteed, and is convenient to draw materials.
The anchor net than comparatively dense is laid at the top of three-core bow member 1, prevents from that voussoir from falling to hurt sb.'s feelings.
In addition, in order to guarantee safety, per two meters of construction area the cave of hiding just is set, the cave of hiding is to be made with rail and sleeper, guarantee the constructor safety.
The support component of the main hole danger arch that the utility model provides very safe ready ground supports main hole danger arch, the constructor can be safely that the voussoir of deformation place breakage is taken out one of a displacement is new, behind whole displacement end-of-jobs, remove all support components, even if whole repair is finished.
Compared with prior art, the support component of the main hole danger arch that the utility model provides has the following advantages: it had not both destroyed the main hole overall structure, can replace on safe ready ground again, can prevent because of the interaction between danger voussoir head, bring collapsing of whole danger arch, reduce a large amount of material consumptions, saved a large amount of time and expense.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can in the situation that does not break away from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
