Abstract

The utility model discloses a light-weight polymer anti-slip top beam for supporting and protecting single prop used during mining or road-heading in coal mine. The top beam is formed from a polymer and auxiliary materials such as a fire retardant and an antistatic agent by integrally casting or molding, pawl pits matched with pawls on the prop are symmetrically formed on both sides of the bottom of the beam body at equal distance, and an anti-slip rib in mesh shape is arranged on the top surface of the beam body. The top beam has the advantages of high compressive strength, light weight, slippage prevention, fire retardation, static resistance, corrosion resistance, high recovery rate, low comprehensive cost, safe and reliable usage, arbitrary adjustment of fulcrum according to the protection requirement, simple production cost, and two-side usage. The top beam is particularly suitable for protection of single hydraulic prop or single frictional prop.

Description

The light-duty anti-skidding back timber of macromolecule
Technical field
The back timber that the utility model uses the individual prop supporting to use when relating to colliery down-hole coal excavation or driving, the light-duty anti-skidding back timber of especially a kind of macromolecule.
Background technology
Adopt individual prop complexed metal bar timbering still very general when colliery down-hole coal excavation or driving.Metal roof bar exists that weight is big, easy-to-rust, non-skid property are poor, be difficult for reclaiming, defectives such as labour intensity is big, waste resource, and can only install and use and adjust inconvenience at permanent position, back timber two ends mounting column; There are problems such as intensity is low, non-skid property is poor, processing difficulties in other high polymer substitute products.
Summary of the invention
The purpose of this utility model provides the light-duty anti-skidding back timber of a kind of macromolecule, overcomes the above-mentioned defective of prior art.
The technical scheme that its technical problem that solves the utility model adopts is: the light-duty anti-skidding back timber of a kind of macromolecule, comprise beam body, claw nest, anti-skidding muscle, reclaim the chain hole, at beam body end face the anti-skidding muscle of reticulate pattern is arranged, or be provided with the anti-skidding muscle of reticulate pattern in beam body end face and bottom surface simultaneously; At the equidistant claw nest that matches with the pillar upper clipping claw that is provided with of beam body bottom surface bilateral symmetry, or the claw nest is set simultaneously in beam body bottom surface and end face; Have recovery chain hole at beam body either side or both sides.
The beam body adopts high molecular polymer to add fire retardant, the integral cast of antistatic additive auxiliary material or compression molding.
Good effect of the present invention is: owing to adopt such scheme, make this back timber have compressive strength height, in light weight, antiskid, fire-retardant, antistatic, corrosion-resistant, reclaim reusability height, integrated cost low, safe and reliable, can adjust characteristics such as fulcrum, production technology is simple, the two sides all can be used arbitrarily according to the supporting needs.Can alleviate labor strength more greatly, improve supporting quality, save support cost, be the better scheme of alternative metals back timber.This back timber is compared with the metal roof bar of identical Area of bearing, weight saving 50%, and mechanical strength reaches the metal roof bar technical requirements fully, and antiskid frictional force improves 2~3 times, is highly suitable for hydraulic single prop or the supporting of monomer friction prop and uses.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the drawing in side sectional elevation of Fig. 1;
Fig. 3 is the top plane view of Fig. 1.
Among the figure: 1 beam body, 2, the claw nest, 3, anti-skidding muscle, 4, reclaim the chain hole.
The specific embodiment
As shown in Figure 1, at the equidistant claw nest 2 that matches with the pillar upper clipping claw that have a structure as shown in Figure 2 of beam body 1 bottom surface bilateral symmetry,, also can open claw nest 2 simultaneously in beam body bottom surface and end face so that adjust fulcrum arbitrarily according to the supporting needs.As Fig. 2, shown in Figure 3, beam body 1 end face has the anti-skidding muscle 3 of reticulate pattern, and the anti-skidding muscle 3 of reticulate pattern also can be arranged simultaneously in beam body end face and bottom surface, and is to improve the back timber utilization rate, easy to use.Have recovery chain hole 4 at beam body either side or both sides.
