Abstract
The invention discloses a mine I-steel trapezoidal shed with a bottom beam and solves the problem that the existing underground coal mine supporting equipment structure is unsatisfactory to supporting of roadways in poor geographical conditions. The mine I-steel trapezoidal shed is characterized by comprising a cross beam 1, two support legs 2 and a bottom beam 3. The support legs 2 are fixedly connected to two ends of the cross beam 1 through bolts. The bottom beam 3 longer than the cross beam 1 and parallel with the same is disposed between the two support legs 2. After fixation, the trapezoidal shed is formed. The mine I-steel trapezoidal shed has the advantages of simple and reasonable design structure, stability in supporting, less proneness to bending and deformation, high safety coefficient, convenience in operation, flexibility in construction, safety and reliability, and is applicable to supporting of coal mine roadways.
Description
Technical field:
The invention belongs to the technical field that support apparatus in coal mine is made, be specifically related to a kind of band bottom girder miner steel ladder type canopy, be adapted to colliery tunnel support and use.
Background technology:
Known to the inventor, the general employing of the coal mine roadway steel lining universal standard MT143.86 of Ministry of Coal Industry belongs to coal mine downhole safety supporting product, and the supporting product that uses common standard to produce is a crossbeam above being, material is the 20MnK mining i beam; Both sides are oblique supporting leg, because geological conditions is changeable, very complicated under the coal mine.The location that has requires flitching to increase.Its operating location personnel are many, plant equipment is many.Such structure far can not satisfy the roadway support of features as poor geologic condition.
Summary of the invention:
Purpose of the present invention provides a kind of effective geological conditions that solved to loosen exactly for overcoming above deficiency, has prevented a kind of band bottom girder miner steel ladder type canopy that down-hole accident occurs.
Technical scheme of the present invention is to realize like this, described band bottom girder miner steel ladder type canopy, by crossbeam 1, supporting leg 2, bottom girder 3 forms, and a crossbeam 1 is set, and respectively is bolted at two of crossbeam 1 and fixes two supporting legs 2, between two supporting legs 2, with crossbeam 1 bottom girder 3 longer than crossbeam 1 that be arranged in parallel, be fixed into the ladder type frame.Now crossbeam 1 is fixed in back in the construction, at two of crossbeam 1 anchor root supporting leg 2, then bottom girder 3 is fixed between two supporting legs 2 again, be fixed into the ladder type frame.
A kind of band bottom girder miner steel ladder type canopy of the present invention compared with prior art, has the project organization advantages of simple, and supporting is steady, is difficult for flexural deformation, and safety factor higher primary school is easy to operate, and construction is flexible, and cost is low, safe and reliable advantage.
Description of drawings:
Accompanying drawing is a kind of band bottom girder miner steel ladder type booth structure figure
Among the figure: 1. crossbeam, 2. supporting leg, 3. bottom girder
The specific embodiment:
The present invention is described in further detail below in conjunction with accompanying drawing embodiment, a kind of band bottom girder miner steel ladder type canopy as shown in drawings, its structure is by crossbeam 1, supporting leg 2, bottom girder 3 forms, a crossbeam 1 is set, respectively be bolted at two of crossbeam 1 and fix two supporting legs 2, between two supporting legs 2 with crossbeam 1 bottom girder 3 longer than crossbeam 1 that be arranged in parallel, be fixed into the ladder type frame, existing in the construction crossbeam 1 be fixed in back, again at two of crossbeam 1 anchor root supporting leg 2, then bottom girder 3 is fixed between two supporting legs 2, is fixed into the ladder type frame.
Claims (1)
1. be with bottom girder miner steel ladder type canopy for one kind, by band bottom girder miner steel ladder type canopy, by crossbeam (1), supporting leg (2), bottom girder (3) forms, it is characterized in that arranging a crossbeam (1), respectively be bolted at two of crossbeam (1) and fix two supporting legs (2), between two supporting legs (2) with crossbeam (1) bottom girder (3) longer than crossbeam (1) that be arranged in parallel.
