Abstract
The invention discloses an individual hydraulic prop tilting-prevention device and a tilting-prevention method, and belongs to the field of coal mine roof support. The tilting-prevention device includes hoops fixed on individual hydraulic props, and tilting-prevention chains connected between every two neighboring hoops, wherein the tilting-prevention chains are round-link chains, and adjusting devices for adjusting the tensioning degree of the tilting-prevention chains are mounted on the tilting-prevention chains. The benefits are as follows: 1, as the hoops are fixed on the individual hydraulic props and move along with the individual hydraulic props, the individual hydraulic prop tilting-prevention can be realized only by adjusting the tensioning degree of the round-link chains through rotating rigging turnbuckles, and the operation is convenient; 2, the round-link chains and the rigging turnbuckles have high strength, and the tilting-prevention devices fix the individual hydraulic props firmly and reliably, so that the safety coefficient is high; and 3, the phenomenon of disordered ropes in the conventional individual hydraulic prop tilting-prevention method is changed, and further, the individual hydraulic prop tilting-prevention device is simple and artistic, is free from influences by wavy laneways, and is highly applicable.
Description
Technical field
The present invention relates to a kind of hydraulic prop tilting prevention device and anti-down method, belong to coal mine roof plate supporting field.Be mainly used in the anti-down of coal mining and driving face temporary lining equipment.
Technical background
Hydraulic prop is to utilize fluid pressure generation working resistance and realize setting prop and the single collapsible prop of unloading.Hydraulic prop is as the most general supporting equipment of coal mining work plane; Be widely used in coal-face two lane outlets, advance support and other laneway temporary support; But in use occur easily from falling phenomenon such as skew, pushed over when top board is pressed suddenly; Have a strong impact on construction and personal security, therefore, hydraulic prop is anti-down also to be the difficult problem that hydraulic prop in use most is difficult to overcome always.
Usually be employed in the past and use the plastic coated wire ropes ways of connecting to realize the anti-down of hydraulic prop between the adjacent monomer hydraulic prop; But because plastic coated wire ropes intensity is lower; The anti-down safety factor of hydraulic prop is low; And single hydraulic prop body is relatively more chaotic after fastening rope, and anti-down effect is relatively poor.Afterwards, in actual production, also make tilting prevention devices such as the anti-jack of monomer, but all had problems such as anti-down safety factor is low, operation, suspension inconvenience.
Summary of the invention
For solving the anti-Inverse problem of hydraulic prop, through the supporting condition to hydraulic prop structural analysis, combination tunnel fluctuations, the present invention provides a kind of hydraulic prop tilting prevention device,
The present invention realizes through following technical scheme: a kind of hydraulic prop tilting prevention device; Comprise the anchor ear that is fixed on the hydraulic prop; Be connected the anti-jack between adjacent two anchor ears; Described anti-jack is a round-link chain, on anti-jack, the adjusting device that is used to regulate anti-jack tensioning degree is installed.
Described anchor ear is made up of the semicircular rings of picking up the ears two two ends; On the picking up the ears of two ends, have the hole, two semicircular rings link together through the bolt that penetrates in the hole.
Described adjusting device is a wire tensioner; Wire tensioner) a end is the annular connecting ring, is enclosed within on the bolt of anchor ear, and the wire tensioner other end is a hook, is hooked on an end of round-link chain through hook.
A kind ofly utilize the above-mentioned anti-down method of hydraulic prop tilting prevention device:
A, the anchor ear of tilting prevention device on the position in the 200-300mm scope, is convenient to fluid injection and carrying monomer according to unified fixed-site above the hydraulic prop liquid injection port;
B, round-link chain, wire tensioner be separately fixed at the both sides of anchor ear;
C, install hydraulic prop, after installing, the wire tensioner hook is connected with round-link chain on the adjacent monomer,, reach the anti-down purpose of monomer through rotating the tensioning adjusting of wire tensioner realization round-link chain.
The invention has the beneficial effects as follows:
1, the hydraulic prop tilting prevention device is fixed on the monomer through anchor ear, moves with monomer, only needs to realize that through the mode of rotating wire tensioner adjusting round-link chain tensioning degree monomer is anti-down, and is easy to operate.
2, because the intensity of round-link chain, wire tensioner is high, and tilting prevention device fixed to monomer, safety factor is high.
3, changed the anti-down mode of former hydraulic prop and fastened the chaotic phenomenon of rope, this hydraulic prop tilting prevention device is simple, attractive in appearance, and does not receive the influence of tunnel fluctuations, and applicability is stronger.

Among the figure: 1: anchor ear; 2: wire tensioner; 3: round-link chain; 4: hydraulic prop.
The specific embodiment
Further specify structure of the present invention and effect below in conjunction with embodiment.
At first, like Fig. 1, Fig. 2, shown in Figure 3, use the band iron of 50mm to manufacture semicircle anchor ear 1 (anchor ear of making according to diameter of cylinder is used for the hydraulic prop of the above specification of DZ-2.8m) according to the live diameter of post or cylinder body of monomer; With the anchor ear that processes 1 according to unified fixed-site on monomer is lived post.Round-link chain 3, wire tensioner 2 are separately fixed at the both sides of anchor ear; The round-link chain specification is Φ 18 * 64mm, and monomer column adopts 5 loop chains to meet the demands apart from 1m, and the length of round-link chain can suitably be adjusted according to the variation of post distance; It is 16mm that wire tensioner adopts specification, and anchor ear is fixed in the 200-300mm scope of monomer liquid injection port top.
As shown in Figure 4, after monomer installed, the round-link chain 3 that wire tensioner 2 is linked up with on adjacent monomer connected, and realized the tensioning adjusting of round-link chain through rotating wire tensioner, thereby reached the anti-down purpose of monomer.
Effect
The present invention is applied to 7162,7320,7120, the 7141 work plane twice monomer supportings of Long Dong ore deposit respectively, has a better effect.In the use, only need one man operation, through wire tensioner and round-link chain cooperate the realization monomer anti-down, easy to operate, and the anti-down safety factor of monomer is higher; The monomer supporting is good, and after the tilting prevention device suspension finished, whole structure was comparatively succinct, attractive in appearance, and does not receive the influence of tunnel fluctuations.This device extensively comes into operation in each ore deposit of big village company at present, has obtained the consistent favorable comment of applying unit.
