Abstract
The utility model discloses a beam hanging device installation structure for the temporary support of an excavation working surface. The beam hanging device installation structure is characterized in that the exposed tail end of an anchor rod is reserved by a certain length, and the length is larger than the total thickness of two anchor rod nuts and a beam handing device support plate; and the aperture of the beam handing device support plate is enlarged to be 2 millimeters larger than the diameter of the anchor rod. When installation is carried out, firstly the anchor rod is fixed on a tunnel roof by using the anchor rod nuts, the beam hanging device support plate is arranged below the first anchor rod nut, and then a beam hanging device is fixed by using the second anchor rod nut. According to the utility model, when the direction of the beam hanging device is adjusted, because the anchor rod nuts arranged below the beam hanging device support plate are in independent structures, the beam hanging device support plate can rotate by only loosening the anchor rod nuts arranged below the beam hanging device support plate and keeping the original anchor rod nut immovable, and therefore the hanging stability of a forepoling beam is ensured.
Description
Technical field:
The utility model relates to the colliery digging laneway temporary support device, relates in particular to forestope.
Background technology:
During the coal mine roadway driving, some employings tunnel forestope carries out top board temporary lining, and forestope need be installed on the hanging beam device.During installation the hanging beam device towards consistent with the direction of forestope, install smoothly to make things convenient for forestope.Because the hanging beam device relies on former anchor nut to be fixed on the anchor pole, need anchor nut is aimed at anchor pole for adjusting direction during use, with nut and hanging beam device first half integral-rotation, nut is produced loosening, this hangs stable influential to forestope, may cause potential safety hazard.
Summary of the invention:
The purpose of this utility model is for overcoming the deficiency of existing hanging beam device, existing hanging beam device mounting structure is improved, a kind of new hanging beam device mounting structure is provided, reaching the not integrally rotated purpose of nut and hanging beam device.
Hanging beam device mounting structure during a kind of temporary support for drivage face, it is that outer Rose's head with anchor pole reserves certain-length, this length is greater than the gross thickness of two anchor nuts and hanging beam device supporting plate, and it is greater than bolt diameter 2mm that the aperture on the hanging beam device supporting plate is expanded.
During installation, first anchor pole is fixed on the back with anchor nut, hanging beam device supporting plate is installed in below the first anchor nut, with the second anchor nut the hanging beam device is fixed again.
The utility model advantage is: when adjusting hanging beam device direction, because the anchor nut that is installed under the supporting plate is absolute construction, only need the anchor nut under the loosening hanging beam device supporting plate, it is motionless that former anchor nut keeps, hanging beam device supporting plate is namely rotatable, has guaranteed the stability that forestope is hung.
Description of drawings
Fig. 1 is the front view of the utility model embodiment.
Among the figure: 1-supporting plate, 2-anchor pole, 3-the first anchor nut, 4-the second anchor nut.
The specific embodiment
As shown in Figure 1, hanging beam device mounting structure during a kind of temporary support for drivage face, the structure of hanging beam device such as Fig. 1, it has a supporting plate 1, it is large and anchor pole 2 diameter 2mm that aperture on the supporting plate 1 is expanded, outer Rose's head with anchor pole 2 during installation reserves certain-length, this length is greater than the gross thickness of two anchor nuts 3 and supporting plate 1, during installation, first anchor pole 2 usefulness the first anchor nut 3 is fixed on the back, hanging beam device supporting plate 1 is installed in below the former anchor nut 3 again, is screwed on outer Rose's head of anchor pole 2 with the second anchor nut 4 again, the hanging beam device is fixed.
Claims (1)
1. the hanging beam device mounting structure a during temporary support for drivage face is characterized in that, it is that outer Rose's head with anchor pole reserves certain-length, and this length is greater than the gross thickness of two anchor nuts and hanging beam device supporting plate; It is greater than bolt diameter 2mm that aperture on the hanging beam device supporting plate is expanded.
