Abstract
The utility model discloses a disk supporting board metal strip, characterized in that the utility model comprises a disk supporting board (1), a disk metal strip (2), an anchor rope (3), an anchor rope cartridge (4), an anchor rope hole (5), a wall rock (6) and an anchor tool (7), wherein the disk supporting board (1) is equipped as the broad band disk; the disk metal strip (2) matched with the disk supporting board (1) is a disk metal strip; and one head of the anchor rope (3) is fastened with the disk metal strip (2), the anchor rope hole (5) on the wall rock (6), and the anchor rope cartridge (4) through the disk supporting board (1), and the other head uses anchor tool (7) to support and anchor the disk supporting board (1), the disk metal strip (2) and the wall rock (6) as a whole. Compared with the traditional metal strip, the utility model has the advantages of good bending resistance, high supporting intensity, large supporting area, flexible operation, low cost, compact structure, security, practicability and reliability, especially applicable for the mine underground supporting.
Description
Technical field:
The utility model belongs to the technical field that mining machinery is made, and is specifically related to a kind of dish-shaped supporting plate steel band, is particularly useful for mine down-hole support steel band.
Background technology:
At present, the support material that uses under the coal mine mostly is the reinforcing bar steel band, and the reinforcing bar steel band is in light weight, and processing is simple, but stiffness is very little, and the effective support area is little, and is relatively poor to the roof timbering effect.Though also have some different in nature steel band supporting effective areas big, stiffness is big, anti-bending strength is better, but its tear resistance is poor, particularly when roof pressure was big, supporting plate was very easy to be pressed into steel band, caused steel band to tear, more than several support materials be easy to cause supporting failure, cause roof collapse, occur roof fall accident when serious, be difficult to adapt to the big section in down-hole, the gob side entry of large span especially more cannot say for sure to demonstrate,prove the safety of its supporting under the common complex conditions such as high-ground stress in down-hole, mine.
Summary of the invention:
The purpose of this utility model is exactly in order to overcome above deficiency, the dish-shaped supporting plate steel band that a kind of flexing resistance that provides is good, supporting intensity is big, safe and reliable.
The utility model is to realize like this, a kind of dish-shaped supporting plate steel band is by dish-shaped supporting plate (1), dish steel band (2), anchor cable (3), anchor cable powder stick (4), anchor cable hole (5), country rock (6), ground tackle (7) is formed, what it is characterized in that dish-shaped supporting plate (1) is set to the broadband dish, with the dish-shaped steel band (2) of the supporting setting of dish-shaped supporting plate (1) be dish-shaped steel band, (3) one of anchor cables are firm to anchor cable powder stick (4) with the anchor cable hole (5) on dish-shaped steel band (2) and the country rock (6) by dish-shaped supporting plate (1), and the other end uses ground tackle (7) with dish-shaped supporting plate (1), dish steel band (2) and country rock (6) Trinity support anchoring.The technical problem of its solution is: dish-shaped steel band both sides machined grooves shape, both improved the intensity on steel band both sides, improved the stressed harmony of whole piece steel band again, the holder load that draws the power of dialling and steel band of anchor cable has been mated rationally more, thereby improved the cable bolting effect; Dish supporting plate and supporting identical the contacting of dish-shaped steel band, the lifting surface area of the anchor cable mouth steel band that has increased, thus make steel band entire body stress equalization, improved the cable bolting effect.
Dish-shaped supporting plate steel band of the present utility model has that flexing resistance is good, supporting intensity is high, and the supporting area is big, flexible operation, and cost is low, compact conformation, the reliable advantage of safe and applicable.
Description of drawings:
Accompanying drawing is dish-shaped supporting plate steel band structure chart
1. dish-shaped supporting plate, 2. dish-shaped steel band, 3. anchor cable, 4. anchor cable powder stick, 5. anchor cable hole, 6. country rock, 7. ground tackle,
The specific embodiment:
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing,
Dish-shaped as shown in drawings supporting plate steel band is to adopt hot rolling or cold-rolled steel sheet, the band steel, by continuous compacting by rolling dish supporting plate of cold rolling unit (1) and dish-shaped steel band (2), punching placed in the middle, will with of the corresponding anchor cable in hole (3) by passing in dish-shaped supporting plate (1) mesopore and dish-shaped steel band (2) mesopore, firm by anchor cable hole (5) to anchor cable powder stick (4), the other end uses ground tackle (7) with dish-shaped supporting plate (1), dish steel band (2) and country rock (6) Trinity support anchoring, and add fasteningly, make dish-shaped steel band, the dish supporting plate, become a more unified supporting integral body between the anchor cable three.
