Abstract
The invention discloses a support for a coal mine. The support comprises a top beam track and a base track. An upper guide wheel is arranged on one side of the top beam track. An upper drive wheel is arranged on the other side of the top beam track. A lower guide wheel is arranged on one side of the base track. A lower drive wheel is arranged on the other side of the base track. Hydraulic uprights are arranged between the top beam track and the base track. A four-bar linkage device is installed in the middle positions of the hydraulic uprights. Rotary shafts are arranged in the middle of the four-bar linkage device. The support can be flexibly used in coal mining, the coal mine can be conveniently supported in explosion, safety of workers and the coal mine in the mining process is guaranteed, the automation degree is high, stability is high, cost is low, practical performance is good, expansibility performance is excellent, design is novel, a good creative scheme is raised, and the support has great market popularization prospects.
Description
Technical field
The present invention relates to technical field of coal mine, particularly relate to the support that a kind of colliery uses.
Background technology
Colliery is the proportional space that the mankind excavate when digging and being rich in the geological stratification of coal, generally includes tunnel, well cave and face etc.Coal is topmost solid fuel, is the one of kaustobilite.It is by the plant in great numbers grown certain geological epoch, in suitable geological environment, is piled into thick-layer gradually, and is buried in the bottom or silt, formed through very long geochronic natural incoalation.In the world in Various Geolcgical Ages, maximum with producing coal in the stratum in the Carboniferous Period, the Permian Period, Jurassic Period and the Tertiary Period, be important coal-forming age.The phosphorus content of coal is generally 46 ~ 97%, in brown to black, has dim to metallic luster.According to the difference of degree of coalification, coal can be divided into peat, brown coal, bituminous coal and anthracite four class.Colliery often needs explosion in the process of exploitation, and just need when explosion to support hack lever below, prevent from caving in, the personnel that cause hinder busy, and the stability of current support is not good, there is deficiency.
In sum, for the defect of prior art, the special support needing a kind of colliery to use, to solve the deficiencies in the prior art.
Summary of the invention
For the deficiency that prior art medium-height trestle exists, bring very large drawback to actual employing, the present invention proposes the support that a kind of colliery uses, novel in design, is convenient to use when coal mining, to address the deficiencies of the prior art.
To achieve these goals, technical scheme of the present invention is as follows:
The support that a kind of colliery uses, comprise back timber crawler belt and base crawler belt, the side of back timber crawler belt is provided with directive wheel, the opposite side of back timber crawler belt is provided with driving wheel, the side of base crawler belt is provided with lower directive wheel, and the opposite side of base crawler belt is provided with lower driving wheel, is provided with hydraulic vertical prop between back timber crawler belt and base crawler belt, the centre of hydraulic vertical prop is provided with double leval jib device, and the centre of double leval jib device is provided with turning cylinder.
Skeleton is provided with in the centre of back timber crawler belt of the present invention and base crawler belt.
Further, the flexible height of described hydraulic vertical prop is 10m-100m.
The invention has the beneficial effects as follows: this product structure is simple, can be used in coal mining flexibly, conveniently the colliery in explosion be supported, ensure that workman and the colliery safety in recovery process, and automaticity is high, stability is strong, and with low cost, and Practical Performance is good, Scalable Performance is excellent, modern design, is a kind of well innovation scheme, has very much marketing prospect.
Accompanying drawing explanation
The present invention is described in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is structural representation of the present invention.
detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
See the support that Fig. 1, a kind of colliery use, comprise back timber crawler belt 100 and base crawler belt 110, the side of back timber crawler belt 100 is provided with directive wheel 111, the opposite side of back timber crawler belt 100 is provided with driving wheel 112, the side of base crawler belt 110 is provided with lower directive wheel 113, the opposite side of base crawler belt 110 is provided with lower driving wheel 114, hydraulic vertical prop 130 is provided with between back timber crawler belt 100 and base crawler belt 110, the centre of hydraulic vertical prop 130 is provided with double leval jib device 120, and the centre of double leval jib device 120 is provided with turning cylinder 140.
Skeleton 150 is provided with in the centre of back timber crawler belt 100 of the present invention and base crawler belt 110.The flexible height of hydraulic vertical prop 130 is 10m-100m.
The present invention is effective is: structure is simple, can be used in coal mining flexibly, conveniently the colliery in explosion be supported, ensure that workman and the colliery safety in recovery process, and automaticity is high, stability is strong, and with low cost, and Practical Performance is good, Scalable Performance is excellent, modern design, is a kind of well innovation scheme, has very much marketing prospect.
The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
