Abstract
The invention relates to the field of mine machines, and discloses a supporting frame of roadway surrounding rock. According to the structure of the supporting frame of the roadway surrounding rock, one end of an anchor rod (3) is fixed to the surrounding rock (5), a protective net (4), an M-type steel belt (1) and a tray (2) are sequentially installed on the anchor rod (3) through nuts, the radian of grooves of the M-type steel belt (1) is smaller than that of the tray (2), and the tray (2) is made of spring steel. The supporting frame of the roadway surrounding rock has the advantages of being simple in structure, convenient to manufacture and capable of achieving efficient and mass production; compared with a W-type steel belt, the M-type steel belt has a better mechanical property and is better in aspect of stress intensity, flexure strength and the like. On the rock stratum with the good geological condition, materials are saved by more than 50% than that of a U-type steel support, and therefore the cost of the supporting frame is lowered, and underground supporting is convenient, rapid and practical. The two edges of the M-type steel belt are circular arc faces, an underground protective net is prevented from being damaged when the M-type steel belt makes contact with the underground protective net, and underground supporting is safer.
Description
one, technical field
The present invention relates to mining machinery field, particularly a kind of support bracket of Surrounding Rock Masses of Roadway.
two, background technology
The steelframe of now conventional supporting Surrounding Rock Masses of Roadway is U-shaped bracket support, and the supporting of W steel band, and U-shaped bracket support exists processing throughput low, long-distance transportation difficulty; , at the good underworkings of geological conditions, with U-shaped bracket support, there is the defects such as waste of material in down-hole carrying inconvenience.And W steel band of model two edges are straight flange, when supporting, easily protective screening are cut off, thereby make protective screening lose due protective action.
Three,
summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of support bracket of Surrounding Rock Masses of Roadway, the technical scheme that the present invention intends adopting is: it is upper that one end of anchor pole (3) is fixed on country rock (5), and protective screening (4), M steel band of model (1) and pallet (2) are installed successively and used nut on anchor pole (3); The groove radian of M steel band of model (1) is less than the radian of pallet (2), and pallet (2) is made by spring steel; Beneficial effect of the present invention is: simple in structure, easy to make, can realize efficient, mass production, and compared with W steel band of model, compared good mechanical property simultaneously, at aspects such as being subject to force intensity, flexural strength, be all better than W steel band of model.In the good rock stratum of geological conditions, more than 50% material has been saved in more U-shaped steel supporting, thereby makes product cost reduce, make down-hole supporting more convenient, practical.M steel band of model two edges are arc surface, can protect the unlikely destruction of protective screening when contacting with down-hole protective screening, make down-hole supporting safer, and M steel band of model bottom is provided with pallet, and supporting is more firm.
four, accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, M steel band of model 2, pallet 3, anchor pole 4, protective screening 5, country rock
five, the specific embodiment
Embodiment 1: its structure is: a kind of support bracket of Surrounding Rock Masses of Roadway, and it is upper that one end of anchor pole (3) is fixed on country rock (5), and protective screening (4), M steel band of model (1) and pallet (2) are installed successively and are used nut on anchor pole (3); The groove radian of M steel band of model (1) is less than the radian of pallet (2), and pallet (2) is made by spring steel.
Claims (1)
1. the support bracket of a Surrounding Rock Masses of Roadway, one end of anchor pole (3) is fixed on country rock (5), protective screening (4), M steel band of model (1) and pallet (2) are installed successively and are used nut on anchor pole (3), it is characterized in that: the groove radian of M steel band of model (1) is less than the radian of pallet (2), and pallet (2) is made by spring steel.
