Abstract
The invention discloses a three-dimensional special type steel belt and solves the problems of insufficient tension and poor effect of coal mine supporting intensity. The three-dimensional special type steel belt is characterized in that the three-dimensional type steel belt comprises a hex nut (1), a three-dimensional steel belt (2) and an anchor stock; a V-shaped convex groove is formed in the middle of the three-dimensional steel belt (2), a central hole (4) is formed on the V-shaped convex groove, and two V-shaped convex grooves (5) are formed at two ends of the central hole (4) in a symmetrical mode; and one end of the anchor stock (3) is fixedly arranged on a coal seam roof and the other end penetrates through the central hole (4) to be fixed through the hex nut. The three-dimensional special type steel belt has the advantages of being great in intensity tension, large in junction surface, small in space occupation, low in labor intensity, low in supporting cost, good in supporting effect and applicable in coal mine channel supporting.
Description
Technical field:
The invention belongs to the technical field that coal mine machinery equipment is made, be specifically related to a kind of three-dimensional special type steel band, be adapted to colliery tunnel support.
Background technology:
Known to the inventor, just band is former coal ministerial standard MT/T861-2000 mining supports product, and its material is the steel plate Q235 of 3 millimeters of thickness, and section configuration is the reinforcing rib roll forming of 60 ° of twice.Under coal mine, cooperate anchor pole, anchor cable Strengthening Roof and tunnel facade, to the conclusive effect of having kept the safety in production.Present steel band a multitude of names of using of coal mine support has plenty of that the intensity pulling force is inadequate, bonding surface is little, does not have the effect of safety support; Although the pulling force that has is enough strong, volume is excessive, takes up room, and labor strength increases, and causes the down-hole support cost to strengthen.Impact is normal produces.
Summary of the invention:
Purpose of the present invention provides a kind of supporting effect good exactly for overcoming above deficiency, and cost is low, and labour intensity is little, the three-dimensional special type steel band that the intensity pulling force is large.
Technical scheme of the present invention is to realize like this, described a kind of three-dimensional special type steel band, by hex nut 1, three dimensional type steel band 2, anchor pole 3 forms, and it is characterized in that arranging a three dimensional type steel band 2, V-type tongue at three dimensional type steel band 2 middle parts is provided with centre bore 4, be symmetrical arranged two V-type tongues 5 at the two ends of centre bore 4, one of anchor pole 3 is fixed in roof with Anchor Agent, and steel band centre bore 4, female fixing with the spiral shell hexagonal is passed in the other end.
Three-dimensional special type steel band of the present invention, compare with other steel bands: have that the intensity pulling force is large, bonding surface is large, it is little to take up room, and labor strength is little, and support cost is low.The advantage that supporting effect is good
