Abstract
The utility model relates to a multifunctional column shoe and column cap for a mine, which consists of a support surface, reinforced bars and a shoe upper, the shoe upper is shape like a thin cylinder and positioned on the support surface, a hydraulic prop inosculating slot is formed at the center of the shoe upper, a hydraulic prop top plate cat claw embedding hole is formed on the end surface, the reinforced bars which are connected with the support surface are symmetrically arranged on the periphery of the shoe upper, anti-skid bars are arranged on the bottom surface of the support surface, and a recovery hole is arranged on any one reinforced bar or the flange of the support surface. The multifunctional column shoe and column cap for the mine adopts rigid polyurethane or rigid nylon as raw material and uses injection molding or compression molding, thereby reducing the weight by 7-9 times in comparison with a steel cast shoe, enhancing the strength by 3-4 times, being characterized by light weight, high strength, good toughness, simple structure, convenient operation, easy recovery, repeated use, acid and alkali resistance, strong anti-cold ability and long service life, and being widely used in a variety of mines and tunnels.
Description
Technical field
The utility model relates to the accessory of coal-face bracing or strutting arrangement under the coal mine, specifically relates to the base of hydraulic prop and the pad of taking over a business, i.e. post footwear and cap.
Background technology
Coal mine lower support hydraulic prop, because base and to take over a business relative area less, pressure ratio is more concentrated, occurs roof fall easily and wears at the end.In order to address this problem, be the pad of making definite shape with steel mould in the past, be used for be called " the post footwear " below the base, what be used to take over a business is called " cap ", to reach the purpose of support.But the post footwear cap made from iron and steel is very heavy, needs the several people lifting and installs, and workman's operation is wasted time and energy, also often flowed or blow over and cover completely and can't take out, cause very big waste, if do pad with plank by coal, usually be pressed down again or slippage, and be difficult for reclaiming, cause many unsafe factors.For many years, the miner thirsts for having a kind of product in light weight, easy to operate, not fragile, long-lived to replace very much.
Summary of the invention
The purpose of this utility model is to overcome the weak point of above-mentioned post footwear cap, design a kind of light-duty, can reclaim reusable mining multifunctional post footwear cap.
The purpose of this utility model is achieved in that mining multifunctional post footwear cap, form by supporting surface, strength bar and upper of a shoe, upper of a shoe is the thin column shape, be positioned on the supporting surface, central authorities at upper of a shoe are provided with the identical groove of hydraulic prop, and the end face of upper of a shoe is provided with hydraulic prop and takes over a business the ram's horn inlaid hole, is arranged with the strength bar that connects supporting surface around the upper of a shoe, make pressure further to diffusion all around, whole employing injection moulding of post footwear cap or compression molding.
The utility model also is provided with the anti-skidding muscle of projection on the bottom surface of supporting surface, form the grid of a plurality of equalizations by moving towards about anti-skidding muscle to distribute, and can play and keep a firm hand on ground, firmly not sliding effect.Supporting surface can be circular, also can be polygon or other shapes.
In order to reclaim conveniently, the utility model can design on any strength bar of mining multifunctional post footwear cap recovery holes, perhaps the edge designs at supporting surface has a recovery holes that connects supporting surface, and on recovery holes, install an anchor chain additional or reclaim rope, so that just post footwear cap can be involved recovery from coal at a distance.
It is raw material that mining multifunctional post footwear cap of the present utility model adopts rigidity polyurethane or rigidity nylon, with injection moulding or compression molding, has alleviated 7～9 times than steel casting footwear on weight, has strengthened 3～4 times on intensity.The utility model can extensively use under various mines, tunnel, have in light weight, intensity is high, good toughness, simple in structure, be convenient to operate, reclaim easily, can reuse and acid-alkali-corrosive-resisting, cold tolerance by force, the characteristics of long service life.

The specific embodiment
Embodiment 1
Structure such as Fig. 1, Fig. 2, shown in Figure 3 of mining multifunctional post footwear cap are made up of supporting surface 1, strength bar 5 and upper of a shoe 2.Upper of a shoe 2 is the thin column shape, is positioned on the supporting surface, is provided with the hydraulic prop groove 6 that coincide in the central authorities of upper of a shoe 2, and end face is provided with hydraulic prop and takes over a business ram's horn inlaid hole 3.When making the post footwear, the bottom of hydraulic prop is inserted in the identical groove 6 of hydraulic prop, firmly coincide together with the identical groove 6 of hydraulic prop; When doing cap, the hydraulic prop that take over a business to insert of hydraulic prop is coincide in the groove 6, and make the ram's horn of hydraulic prop on taking over a business embed hydraulic prop to take over a business in the ram's horn inlaid hole 3, cap is mounted on hydraulic prop takes over a business securely.But this particular design one is dual-purpose, not only can make the post footwear but also can do cap, also can require the split of post footwear cap is produced, used respectively according to the colliery.Whole employing injection moulding of post footwear cap or compression molding.
Be arranged with the strength bar 5 that connects supporting surface 1 around the upper of a shoe 2, can make pressure further to diffusion all around.As shown in Figure 3, on the bottom surface of supporting surface 1, also be provided with the anti-skidding muscle 7 of projection, form the grid of a plurality of equalizations, can play and keep a firm hand on ground, firmly not sliding effect by moving towards about anti-skidding muscle 7 to distribute.Supporting surface 1 can be that circle also can be a polygon.
In order to reclaim conveniently, be provided with a recovery holes 4 that connects supporting surface 1 at the edge of mining multifunctional post footwear cap supporting surface 1, as Fig. 1, Fig. 3, and on recovery holes 4, install an anchor chain additional or reclaim rope, so that just post footwear cap can be involved recovery from coal at a distance.
Embodiment 2
Structure such as Fig. 4, Fig. 5, shown in Figure 6 of mining multifunctional post footwear cap are made up of supporting surface 1, strength bar 5 and upper of a shoe 2.Upper of a shoe 2 is the thin column shape, be positioned on the supporting surface, be provided with the hydraulic prop groove 6 that coincide in the central authorities of upper of a shoe 2, end face is provided with hydraulic prop and takes over a business ram's horn inlaid hole 3, be arranged with the strength bar 5 that connects supporting surface 1 around the upper of a shoe 2, the bottom surface of supporting surface 1 is provided with the anti-skidding muscle 7 of projection.
