The pallet that in prior art, bolt support is used is generally in square, rectangle or circular slab equipment structure, it causes pallet intensity low due to reasons such as materials, supporting effect is poor, and in the breaking roof supporting of colliery, broken rock mass is easily caving from anchor rod pallet board slippage, anchor rod pallet board effect is caused to lose efficacy, have a strong impact on supporting effect, and, in prior art, steel band or reinforcing bar beam need to determine its length according to different back situation, there is its limitation, from underaction in the outfit of different drift section size; In addition, owing to lacking the longitudinally steel bar ladder in (along tunnelling direction) or the supporting of steel plate, make to protect top area and greatly reduce, easily form " string bag ", effectively can not improve the supporting effect of top board, leave hidden danger to the safety in production in colliery.
Utility model content
In order to solve above-mentioned problems of the prior art, the utility model proposes a kind of anchor plate for mining, this pallet both can adapt to the supporting of different size back, flexible, strong adaptability; Also add the syndeton in tunnel horizontal and vertical (tunnelling direction), controlroof surrouding rock deformation can sink well, prevent the generation of " string bag " phenomenon.
Its technical solution comprises:
A kind of anchor plate for mining, it comprises tray main body and cross steel plate, described tray main body center is arch boss, the center of described arch boss is provided with spacing hole, the diameter of described spacing hole is greater than the diameter of anchor pole, and described tray main body is positioned at the center of described cross steel plate, and described cross steel plate is overlapped by four strip steel plates and formed, every bar strip steel plate is provided with strip draw-in groove away from one end of tray main body, is provided with several manholes in described strip draw-in groove.
As a preferred version of the present utility model, above-mentioned manhole and bolt, nut screw connection use, for fixing to adjacent pallet overlap joint; Criss-cross anchor rod pallet board overlaps mutually one by one, considerably increases the density of protecting top.
As another preferred version of the present utility model, above-mentioned manhole is provided with four, and the interval between adjacent circular through hole is 50mm.
The length of every bar strip steel plate is 500mm, and width is 50mm, and thickness is 15mm; The length of strip draw-in groove is 165mm, and the degree of depth is 5mm.
The utility model proposes a kind of anchor plate for mining, it is on the basis of prior art tray main body, set up cross steel plate, criss-cross steel plate is formed centered by tray main body by four strip steel plates, and one end away from tray main body of every bar strip steel plate is provided with strip draw-in groove, four manholes are provided with in every bar strip draw-in groove, adjacent pallet is by manhole and bolt, nut screw connection overlaps mutually, the criss-cross structure of mutual overlap joint composition, the supporting of different size back can be adapted to, flexibly and easily, strong adaptability, and add the syndeton in tunnel horizontal and vertical (tunnelling direction), instead of traditional steel band or steel bar ladder, define a criss-cross steel plate, adjacent anchor rod pallet board overlaps mutually, considerably increases the density of protecting top.
The utility model is especially specially adapted to the supporting to breaking roof, it can sink well in controlroof surrouding rock deformation, cross steel plate can effectively play the effect of lifting wire lath, makes it be close to roof rock surface, prevents the generation of " string bag " phenomenon.
The utility model anchor rod pallet board is easy to process, structure is simple, workable.

Fig. 2 is the assembling drawing of the utility model anchor rod pallet board;
In figure: 1-tray main body, 2-arch boss, 3-manhole, 4-spacing hole, 5-strip steel plate, 6-strip draw-in groove, 7-anchor pole, 8-nut one or tight loop.
Detailed description of the invention
The utility model discloses a kind of anchor plate for mining, in order to make advantage of the present utility model, technical scheme clearly, clearly, below in conjunction with specific embodiment, explanation clear, complete further being done to the utility model.
Shown in composition graphs 1, the utility model, a kind of anchor plate for mining, formed by the cutting of monoblock steel plate punched, it comprises tray main body 1 and cross steel plate, the center of tray main body 1 is arch boss 2, the similar of pallet in the structure of tray main body 1 and prior art, do not elaborate herein, spacing hole 4 is positioned at the center of arch boss 2, anchor pole 6 can pass from spacing hole 4, the diameter of the preferred spacing hole 4 of the utility model is slightly larger than the diameter of anchor pole 6, anchor pole 6 is used nut 1 through after spacing hole 4, be fixed on tray main body, select nut one to be fixed under normal circumstances, when using pipe-seam type anchor rod, tight loop 8 is then selected to be fixed.
Cross steel plate is formed centered by tray main body by four strip steel plates 5, one end of every bar strip steel plate is fixed on tray main body, the other end is provided with strip draw-in groove 6, namely strip draw-in groove 6 is arranged in the one end away from tray main body, manhole 3 is provided with in strip draw-in groove 6, cooperation by bolts and nuts completes the supporting of overlap joint between cross pallet and top board, by diverse location place in strip draw-in groove 6 manhole 3 between mutual collocation can adapt to the supporting of different size back.
Cross steel plate adds the syndeton of tunnel vertical and horizontal, instead of traditional steel plate and steel bar ladder, defines a criss-cross plate girder, one by one the overlap joint of strip steel plate, substantially increases the density of protecting top.
Criss-cross steel plate can effectively play the effect of lifting wire lath, makes it be close to roof rock surface, prevents the generation of " string bag " phenomenon.
Embodiment 1:
Choose 4 strip steel plates 5, arrange in cross, Central Symmetry, its wall scroll strip steel plate 5 length is 500mm, width is 50mm, thickness is 15mm, the degree of depth of strip draw-in groove 6 is 5mm, and length is 165mm, the diameter 15mm of manhole, most inner circular through hole center to center distance tray main body 1 edge is 300mm, the distance 50mm between adjacent circular through hole; Tray main body 1 length of side 150mm, arch boss 2 lower limb diameter 80mm, height of projection 30mm, spacing hole 4 aperture 24mm.
As shown in Figure 2, during use, anchor pole 7 through the anchor pole spacing hole 4 at tray main body 1 center, then is screwed through screw thread by nut 1, and anchor pole 7 and pallet are fastened to each other, and strip steel plate 5 effectively lifts wire lath, makes it be attached to top board surface;
Multiple cross anchor rod pallet board is by the mutual collocation between diverse location place manhole 3 in strip draw-in groove 6, and attaching nut bolt is fixed, and completes the overlap joint between strip steel band, can adapt to the supporting of different size back; And provide the roof timbering in top board horizontal and vertical (tunnelling direction), eliminate the use of steel bar ladder and steel plate simultaneously, increase the support density of top board, prevent the generation of " string bag " phenomenon and sillar avalanche from hurting sb.'s feelings or equipment.
