Abstract
The utility model relates to a mine direction-adjusting supporting plate. The problems that mine underground tunnel supports are inconvenient to assemble and disassemble, the anchoring performance is poor, and off tracking of anchor rods and anchor cables is caused are solved. The mine direction-adjusting supporting plate is characterized in that a trapezoid tray (3) with the wide upper portion and the narrow lower portion is arranged, a semi-circular groove (5) is formed in the middle of the lower bottom plane of the trapezoid tray (3), an outer conic anchor rod and anchor cable connecting hole (2) is formed in the middle of the semi-circular groove (5), a cylinder (4) with the semi-arc-shaped outer end is arranged in cooperation with the semi-circular groove (5), and the outer end is characterized in that an inner conic anchor rod and anchor cable connecting hole (1) is formed in the center of the cylinder (4) with the semi-arc-shaped outer end. The mine direction-adjusting supporting plate has the advantages that disassembling and assembling are convenient to use, the anchoring performance is good, off tracking of the anchor rods and the anchor cables can be controlled, and the mine direction-adjusting supporting plate is suitable for the mine underground tunnel supports.
Description
Technical field:
The utility model belongs to the technical field that mining machinery is manufactured, and is specifically related to a kind of mining tuning formula supporting plate, is adapted to mine down-hole tunnel supporting.
Background technology:
At present, the large portion of supporting using under coal mine adopts the supporting of reinforcing bar steel band small size supporting plate, although reinforcing bar steel band is lightweight, processing is simple, and stiffness is very little.Effective support area is little, poor to roof timbering effect, also have to adopt and have steel band of model supporting, stiffness and anti-bending strength are increased, but its anchor pole supporting area is around little, particularly at the large section of roof collapse or down-hole, the excavating lane supporting of large span, especially mine down-hole common to the complex condition such as high-ground stress be more difficult to ensure the uniformity of its support anchor rod direction of card and ground tackle steel band supporting plate anchor shaft anchor cable connecting hole direction, habitually deviation can be brought very large trouble to support work.Also exist mounting or dismounting inconvenient, the large defect of construction labour intensity simultaneously.
Utility model content:
The purpose of this utility model is exactly in order to overcome above deficiency, the one providing can ensure that support anchor rod anchor cable direction is consistent with ground tackle steel band supporting plate anchor shaft anchor cable connecting hole direction, install and remove convenient, flexiblely, labour intensity is little, the mining tuning formula supporting plate that anchoring property is good.
The utility model is to realize like this, described mining tuning formula supporting plate, it is characterized in that arranging a trapezoidal supporting plate 3 wide at the top and narrow at the bottom, in the in-plane of going to the bottom of trapezoidal supporting plate 3, a semi-circular groove 5 is set, semi-circular groove 5 middle parts are provided with anchor shaft anchor cable connecting hole 2, mate with semi-circular groove 5 that to be equipped with a termination be outer semicircular arc-shaped spheroid 4, outer semicircular arc-shaped spheroid 4 centers are provided with internal circular hollow hole 1.Its operating principle is to be fixed on coal and rock by one of anchor cable or anchor pole, and other end order, through trapezoidal supporting plate 3, outer semicircular arc-shaped spheroid 4, is utilized semi-circular groove 5 and outer semicircular arc-shaped spheroid 4, makes anchor cable keep straight line, not bending, improves anchor cable pulling force.The ancient festival in spring and autumn held on water banks to drink and cleanse away the evil influences arranging between intermediate plate control inner circle cone hollow hole 1 and anchor shaft anchor cable connecting hole 2 connects relation, the firm steel band of anchor cable or anchor pole and supporting plate are locked, due to the interlock that coordinates of the inside and outside circle camber semicircle between supporting plate inner circle cone hollow hole and anchor shaft anchor cable connecting hole 2, adjust the sideslip of controlling anchor cable or anchor pole, walk tiltedly.Make its anchoring more firm.
Mining tuning formula supporting plate of the present utility model, have in the especially big roof bolting of pressure, increase the flexural strength of steel band, increase anchor pole supporting area around, prevent that steel band from tearing and each parts divide, ensure the discharge space of steel band, greatly improved supporting capacity and the anti-bendability of roof timbering, expanded the advantage of effective support area.
Brief description of the drawings
Accompanying drawing 1 is mining tuning formula support board structure figure
1 inner cylinder anchor shaft anchor cable connecting hole in figure, the 2. trapezoidal supporting plate of anchor shaft anchor cable connecting hole 3., 4. outer semicircular arc-shaped spherosome, 5. semi-circular groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model, mining tuning formula supporting plate as shown in Figure 1, its structure is that a trapezoidal supporting plate 3 wide at the top and narrow at the bottom is set, in the in-plane of going to the bottom of trapezoidal supporting plate 3, a semi-circular groove 5 is set, semi-circular groove 5 middle parts are provided with cylindrical cone anchor shaft anchor cable connecting hole 2, mate with semi-circular groove 5 that to be equipped with a termination be the outer semicircular arc-shaped spheroid 4 of semicircular arc-shaped, the outer semicircular arc-shaped spheroid of outer semicircular arc-shaped 4 centers are provided with anchor shaft anchor cable connecting hole 1.When use, one of anchor cable or anchor pole is fixed on coal and rock, and other end order, through trapezoidal supporting plate 3, outer semicircular arc-shaped spheroid 4, is utilized semi-circular groove 5 and outer semicircular arc-shaped spheroid 4, makes anchor cable keep straight line, not bending, improves anchor cable pulling force.Due to the interlock that coordinates of the inside and outside circle camber semicircle due between supporting plate inner circle cone hollow hole and anchor shaft anchor cable connecting hole 2, adjust the sideslip of controlling anchor cable or anchor pole, walk tiltedly, make its anchoring more firm.
