Description
Technical field
The present invention relates to the support apparatus in coal mine technical field, relate in particular to the dismountable top beam hydraulic rack in a kind of colliery.
Background technology
Coal mining, safety is top priority, to this, there are corresponding legal provisions in each state, for example, and in " safety regulations in coal mine " of China regulation: " coal-face must be stipulated immediate support by operating regulation; forbid the operation of sky top, and all supports must set up firmly ".And, for safe working, primary safety requirements is that the exploiting field top board is carried out to reliable safety support, otherwise, must not produce.At present, the safety support equipment of the back timber of employing is mainly comprehensive mining hydraulic bracket, suspension moving hydraulic support and hydraulic prop.For the first two in above-mentioned three kinds of support apparatus, for generally selecting both at home and abroad, its advantage is: self all have locomotive function, and the supporting area is large, supporting intensity is high, security performance is good.But, these two kinds of hydraulic supports also have problems jointly: the volume and weight of support self is all larger, all much much bigger with respect to latter's hydraulic prop, thereby, all more difficult aspect transportation and installation, even relatively lighter suspension moving hydraulic support, in condition, transportation and the installation situation of being obstructed also inevitably appears in poor a little zone, thereby also therefore buried potential safety hazard, and then cause the generation of security incident, especially at the work plane narrow space, ground is pressed large, haulage drift is uneven, bending is not straight, the poor mines of condition such as roadway deformation is serious, the potential safety hazard ubiquity, security incident happens occasionally, simultaneously, because transporting difficulty, some support can can't transport because of the restriction that is subject to specification and weight, thereby cause producing, can't carry out safely.In addition, the third in above-mentioned three kinds of support apparatus is that hydraulic prop is a kind of traditional support apparatus, and the great advantage of its support pattern is exactly that monomer column itself is light, usually only have tens kilograms, be easy to use flexibly, practical, transport also more convenient.But, also there is open defect in hydraulic prop, show: all need manually-operated, labor strength is large especially, repeated work is very frequent, and because of work condition environment relatively severe ubiquity potential safety hazard usually, its safety factor is more much lower than first two hydraulic support stand equipment again, so, be not suitable for general in coal production and long-term the employing.
Therefore, need the poor collieries such as traffic condition for underworkings, work plane mounting condition badly, research and develop and can conveniently transport the support apparatus of installing and can efficiently ensureing production operation safety.
Summary of the invention
The objective of the invention is for the problems referred to above, provide a kind of colliery dismountable top beam hydraulic rack, can adapt to the mine traffic condition, according to needs of production, select the equipment of different size, transport installation, simple and efficient, for safe working provides reliable support apparatus guarantee.
The technical scheme that the present invention deals with problems is: the dismountable top beam hydraulic rack in a kind of colliery, described dismountable top beam hydraulic rack comprises front back timber, rear back timber, connector, gear cash device, sinciput beam stanchion and rear back timber pillar, described front back timber is connected with described rear back timber by connector, described front back timber is connected with the sinciput beam stanchion, described rear back timber is connected with rear back timber pillar, described gear cash device is arranged on the bottom of described rear back timber and the top of described rear back timber pillar, and described sinciput beam stanchion and rear back timber pillar are hydraulically powered pillar.
Further, described connector comprises alignment pin, locating hole, connecting bolt and connecting bolt hole, described locating hole and connecting bolt hole be corresponding being equipped with on the connecting end surface of described front back timber and rear back timber respectively, described alignment pin connects described front back timber and rear back timber by locating hole, and described connecting bolt connects described front back timber and rear back timber by the connecting bolt hole.
Further, be provided with joist below described rear back timber.
Preferably, on the connecting end surface separately of described front back timber and rear back timber, the quantity of described locating hole is more than two, and the quantity in described connecting bolt hole is more than eight, and described locating hole and connecting bolt hole are all symmetrical on each connecting end surface.
In the present invention, for the junction of described front back timber and rear back timber all not at stress concentration point and the near zone thereof of dismountable top beam hydraulic rack Whole Equipment, particularly, according to Mechanical Calculation and Analysis, with the engineering reliability of the safety support of guaranteeing dismountable top beam hydraulic rack integral body.
While applying colliery of the present invention with dismountable top beam hydraulic rack, carry out assembly and disassembly according to needs of production, the especially poor operation for the tunnel condition, can be transported dismountable top beam hydraulic rack equipment with the structure of decomposing, then, assemble application at objective.Application of the present invention is not subject to the restriction of nature geological conditions, for being engaged in a conned space coal mining, the sex-limited very large mine of shipping office, the complete equipment of large specification can't transport, and ensure safety in production, require safety support equipment must guarantee supporting area and the supporting intensity of support, the present invention especially is useful in narrow and small haulage drift the effectively large specification equipment of transportation of realizing.
Compared with prior art, the invention has the beneficial effects as follows: dismountable top beam hydraulic rack novel structure, reasonable in design, easy and simple to handle, structural design optimization, being easy to the workman grasps fast and skillfully uses, effectively solved transportation and the installation question of safety support equipment that is subject to nature geology condition restriction and affects the colliery of production, for safe working with take full advantage of coal resources sufficient guarantee all is provided, be conducive to improve economic benefit and the social benefit in relevant colliery, be adapted at each relevant field and apply.
