Abstract
The invention discloses a double-layer anchor plate, which comprises two single-layer anchor plates, wherein the circumferences of the single-layer anchor plates are fixedly connected with each other through a connecting piece; and inner holes of the single-layer anchor plates are fixedly connected with each other through a pipe fitting. In the double-layer anchor plate provided by the invention, two single-layer anchor plates are fixedly connected into a whole through the connecting pipe and the pipe fitting; and when the double-layer anchor plate is used together with an anchor rod, the exposure length of an anchor rod screw thread is reduced, damages of backblast gangue to the anchor rod are avoided, the double-layer anchor plate can be detached and used repeatedly, the supporting strength and supporting effect of the anchor rod are enhanced, and the supporting cost of the anchor rod is saved.
Description
Technical field
The present invention relates to bolt support technology, relate in particular to a kind of double-deck anchor pole pallet.
Background technology
The anchor pole pallet cooperates anchor pole to accomplish the supporting to rock gangway under the coal mine usually; Existing anchor pole pallet is single layer structure, like Fig. 1, shown in 2, during concrete supporting; Anchor pole 2 threaded ends need pass in the mesopore 11 of anchor pole pallet 1; Tunnel inwall 3 is established in one side 12 holders that make the anchor pole pallet be level, and the not threaded end of anchor pole hangs to be established, as shown in Figure 3; But existing individual layer anchor pole support holder structure, because the threaded part of anchor pole is exposed at the pallet outside, very easily the crumble screw thread of anchor pole of the back spoil of blowing out, most anchor poles can not reuse, and have caused great waste.
Summary of the invention
Double-deck anchor pole pallet provided by the invention is used to overcome defective of the prior art, realizes effectively protection anchor pole, increases the recycling rate of waterused of anchor pole.
The present invention provides a kind of double-deck anchor pole pallet, and this bilayer anchor pole pallet comprises two individual layer anchor pole pallets, and periphery one circle of two said individual layer anchor pole pallets is fixedly connected through connector, and the endoporus of two said individual layer anchor pole pallets is fixedly connected through a pipe fitting.
Double-deck anchor pole pallet provided by the invention is through the integral body that is fixedly connected to form of connector and pipe fitting and two individual layer anchor pole pallets; When being used, not only reduced anchor pole screw thread protruded length, avoided behind the big gun spoil anchor pole that crumbles with anchor pole, the detachable repeated use, and strengthened the supporting intensity and the supporting effect of anchor pole, the supporting expense of having saved anchor pole.

The specific embodiment
Like Fig. 4, shown in Figure 5; The embodiment of the invention provides a kind of double-deck anchor pole pallet; This bilayer anchor pole pallet comprises the first individual layer anchor pole pallet 10 and the second individual layer anchor pole pallet 20; Be fixedly connected through connector 4 between the periphery of the periphery of the first individual layer anchor pole pallet 10 and the second individual layer anchor pole pallet 20, the endoporus 11 of the first individual layer anchor pole pallet 10 is fixedly connected through a pipe fitting 5 with the endoporus 21 of the second individual layer anchor pole pallet.The first individual layer anchor pole pallet 10 and individual layer two anchor pole pallets 20 are prior art, can both on market, buy.
Double-deck anchor pole pallet provided by the invention is fixedly connected to form an integral body through connector 4 and pipe fitting 5 with the first individual layer anchor pole pallet 10 and individual layer two anchor pole pallets 20; When being used, not only reduced anchor pole screw thread protruded length, avoided behind the big gun spoil anchor pole that crumbles with anchor pole 2, the detachable repeated use, and strengthened the supporting intensity and the supporting effect of anchor pole, the supporting expense of having saved anchor pole.
As the concrete implementation of the foregoing description, connector 4 is that many steel bars or spacing of reinforcement arrange that the periphery of the first individual layer anchor pole pallet 10 and the second individual layer anchor pole pallet 20 is welded at steel bar or reinforcing bar two ends respectively.Connector 4 also can be a rectangular steel tube or round steel pipe.Pipe fitting specifically adopts steel pipe, and endoporus 11 peripheries of steel pipe one end and the first anchor pole pallet weld respectively, and endoporus 21 welded of the other end and the second anchor pole pallet guarantee support rigidity, and the length of steel pipe is 30 millimeters, and is suitable with the screw thread length of anchor pole 2.This kind structure fabrication is simple, directly anchor pole is penetrated in the steel pipe during use to get final product, and is very convenient, and its intensity and supporting effect can both satisfy the instructions for use of anchor pole.
What should explain at last is: above each embodiment is only in order to explaining technical scheme of the present invention, but not to its restriction; Although the present invention has been carried out detailed explanation with reference to aforementioned each embodiment; Those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, perhaps to wherein part or all technical characteristic are equal to replacement; And these are revised or replacement, do not make the scope of the essence disengaging various embodiments of the present invention technical scheme of relevant art scheme.
Claims (3)
1. double-deck anchor pole pallet; This bilayer anchor pole pallet comprises two individual layer anchor pole pallets; It is characterized in that, be fixedly connected through connector between the periphery of two said individual layer anchor pole pallets, be fixedly connected through a pipe fitting between the endoporus of two said individual layer anchor pole pallets.
2. double-deck anchor pole pallet according to claim 1 is characterized in that, said connector is many steel bar separation, and the periphery of two said individual layer anchor pole pallets is welded at said steel bar two ends respectively.
