Description
Technical Field
The utility model belongs to the technical field of colliery is coal mining equipment in the pit, specifically speaking relates to an advance hydraulic support.
Background
With the continuous exploitation of coal resources, shallow coal resources are exhausted, and deep coal resources are exploited, so that problems such as the sharp increase of mine pressure need to be faced. The advance hydraulic support is generally adopted to support in a mine roadway, in some deep mines, the roadway of a working face is seriously deformed, the roadway roof is also damaged in different degrees, the flatness is poor, the general advance hydraulic support is difficult to adapt to the uneven roadway roof, the supporting effect is not ideal, the propelling of the working face is seriously influenced, and the normal coal mining work is influenced.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problems, a hydraulic advance support is proposed.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a hydraulic support in advance, includes back timber, base and stand, the stand is equipped with 3, and 3 stand place straight lines enclose into triangle-shaped, the bottom of stand sets up on the base, and its top is articulated with the back timber, and the drive stand goes up and down to make back timber and horizontal plane form 0-40 inclination.
Furthermore, a side guard plate is arranged on the outer side of the base and is connected with the base through a side supporting jack.
Furthermore, one end of the side guard plate is hinged with the base, and the other end of the side guard plate is connected with the piston end of the side support jack.
Further, the side guard plate is hinged to the base and then arranged on the base along the vertical direction.
Furthermore, the side support jack is obliquely arranged, and the cylinder body end of the side support jack is connected with the base.
Furthermore, a bottom adjusting jack is arranged on the base.
Furthermore, the end parts of the base and the top beam are provided with connecting pieces for connecting two adjacent stages of advanced hydraulic supports in series.
The utility model has the advantages that:
the lifting of 3 stand of drive can drive the back timber and remove, makes back timber and horizontal plane form 0-40 inclination, the adaptation tunnel roof unevenness's that can be nimble condition, and simultaneously, when hydraulic support risees, the side guard plate is opened, helps increasing the stability of base, and novel structure is equipped with the end on the base and transfers the jack, and the convenient frame that moves fast reduces workman intensity of labour.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following description, together with the drawings of the present invention, clearly and completely describes the technical solution of the present invention, and based on the embodiments in the present application, other similar embodiments obtained by those skilled in the art without creative efforts shall all belong to the protection scope of the present application. In addition, directional terms such as "upper", "lower", "left", "right", etc. in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for illustrating the present invention and not for limiting the present invention.
The present invention will be further described with reference to the accompanying drawings and preferred embodiments.
The first embodiment is as follows:
as shown in fig. 1-3, the hydraulic advance support comprises a top beam 1, a base 3 and a vertical column 2, wherein the vertical column 2 is a hydraulic vertical column. In order to adapt to the inclination of the roadway roof, the upright columns 2 are 3, the 3 upright columns 2 are not located on the same straight line, specifically, the straight lines where the 3 upright columns 2 are located enclose a triangle, and the stability of the whole advanced hydraulic support is improved. Meanwhile, the bottoms of the upright columns 2 are arranged on the base 3, and the tops of the upright columns are hinged with the top beam 1, namely, the upright columns 2 are driven to lift to drive the top beam 1 to move, and the top beam 1 and the horizontal plane can form an inclination angle of 0-40 degrees by adjusting the lifting amplitude of the 3 upright columns 2.
Current advance hydraulic support generally has two stands to support the back timber, and the back timber adapts to the swing angle less than or equal to 5 of tunnel roof, compares in current advance hydraulic support, the adaptation tunnel roof unevenness's that this application can be nimble the condition.
The outer side of the base 3 is provided with a side guard plate 4, and the side guard plate 4 is connected with the base 3 through a side supporting jack 6. Specifically, one end of the side guard plate 4 is hinged to the base 3, the other end of the side guard plate is connected with the piston end of the side support jack 6, and the cylinder end of the side support jack 6 is connected with the base 3. Preferably, the side supporting jack 6 is obliquely arranged, and the side guard plate 4 is hinged with the base 3 and then is arranged on the base 3 along the vertical direction. When the hydraulic support rises along with the rising of the upright post 2, the side supporting jack 6 extends out, the side guard plate 4 is opened, and the stability of the base 3 is improved.
Meanwhile, the base 3 is provided with a bottom adjusting jack 5, and in the frame moving process, the bottom adjusting jack 5 extends out and supports the coal wall to push the hydraulic support to move to the center of the roadway, so that the frame is convenient to move. In order to facilitate the use of the device for connecting two adjacent stages of advanced hydraulic supports in series, the end parts of the base 3 and the top beam 1 are respectively provided with a connecting piece.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, i.e. the present invention is intended to cover all equivalent variations and modifications within the scope of the present invention.
