More importantly, the supporting of the roadway hydraulic support greatly simplifies the end supporting and advance supporting process of the coal face, improves the operating environment, ensures the safety production and creates good conditions for the quick propulsion of the coal face. At present, the supporting technology of the roadway support is generally applied at home and abroad, and is one of the key technologies essential for realizing high-yield and high-efficiency production of coal mines.
In recent years, the sliding hydraulic support becomes a roadway advanced hydraulic support favored by various coal manufacturers and coal mines, and the sliding hydraulic support has the following advantages: 1. the multi-column support replaces a single column, so that the working efficiency is high; 2. the structure is simple, and the operation is convenient; 3. the weight is light, the cost is low, and the transportation and the installation are convenient; 4. the top plates can be supported in a staggered manner when the row-type top beams move the frame, so that the integrity of the top plates is maintained; 5. the step pitch of the moving frame is large, and the requirements of the advance support time and space can be met.
The sliding support in the prior art is shown in fig. 1 and comprises N top beams, N joists, upright sleeves, uprights, a pushing jack and the like. Wherein the upright posts are arranged on two sides of each joist to support the top plate, and the upright posts bear the load of the top plate through the joists and the top beam. The upper part of the joist is hinged with the top beam, and the lower part of the joist is hinged with the upright post, so that the horizontal component force and the lateral force acted by the top beam of the support can be borne, the torsion resistance of the support is enhanced, and the joist is connected with a pushing jack to ensure the self-moving of the support. As shown in fig. 1, the connecting positions of the upright and the joist are in the width direction of the roadway, and there are 1 connecting positions on the left and right, but if the width of the roadway and the equipment is changed and the distance between the upright of the support cannot be changed, the self-movement of the fore support is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a stand dibit device of support slides.
The utility model aims at realizing through the following technical scheme:
the utility model discloses a stand dibit device of support slides, including the joist, the upper portion and the back timber of joist are connected, and the lower part both ends are connected with the stand respectively, and in tunnel width direction, both ends respectively design has two stand hookup location about the joist, the stand is connected with a hookup location of one of them people.
By the above-mentioned the technical scheme provided by the utility model, the embodiment of the utility model provides a stand dibit device of support slides, respectively the design has two stand hookup location about the joist, if the width of tunnel or equipment changes, can move the stand to needs the position to change the interval of support width and stand, make the leading support that slides move from moving smoothly, guarantee to combine the good operation of adopting working face equipment.

Fig. 1 is a schematic structural view (roadway width direction) of a sliding support in the prior art.
Fig. 2 is a schematic structural diagram (roadway width direction) of the two-position device of the sliding support in the embodiment of the present invention.
In the figure:
1. the device comprises a top beam, 2, a joist, 3, a joist and upright column connecting part, 4, an upright column sleeve, 5, an upright column, 6, a left joist and upright column connecting position II, 7, a left joist and upright column connecting position I, 8, a right joist and upright column connecting position II, 9 and a right joist and upright column connecting position I.
Detailed Description
Embodiments of the present invention will be described in further detail below. Details not described in the embodiments of the present invention belong to the prior art known to those skilled in the art.
The utility model discloses a stand dibit device of support slides, the concrete implementation mode of its preferred is:
the device comprises a joist, wherein the upper part of the joist is connected with a top beam, the two ends of the lower part of the joist are respectively connected with an upright post, the left end and the right end of the joist are respectively provided with two upright post connecting positions in the width direction of a roadway, and the upright posts are connected with one connecting position of one of the upright posts.
The upper part of the joist is hinged with the top beam, and the lower part of the joist is hinged with the upright post.
And an upright post sleeve is arranged outside the upright post.
The sliding support is a fully mechanized mining face roadway advance support and is of a frame type structure integrally.
The support is in a staggered structure of two groups of top beams and is arranged in a mutual push-and-pull mode.
The utility model discloses a stand dibit device of support that slides respectively installs 1 stand about every joist in tunnel width direction, nevertheless the utility model discloses respectively the design has two stand hookup locations about the joist, if the width of tunnel or equipment changes, can move the stand to needs position to change the interval of support width and stand, make the leading support that slides move from moving smoothly, guarantee to combine the good operation of adopting the working face equipment.
The specific embodiment is as follows:
the fully mechanized mining face roadway advance sliding support is of an integral frame type structure, and shields the reversed loader and the crusher under the support, so that the normal operation space of the reversed loader and the crusher is ensured. It is composed of N top beams, N joists, upright sleeves, uprights and pushing jacks. The support adopts a staggered structure of two groups of top beams, and can be pushed and pulled mutually, thereby realizing the self-moving walking action. The structure of the top beam is a row-type staggered rigid structure, and the top beam is hinged with the joist (the joist drives the top beam to move freely). The upright posts are arranged on two sides of each joist to support the top plate, and bear the load of the top plate through the joists and the top beam. The upper part of the joist is hinged with the top beam, and the lower part of the joist is hinged with the upright post, so that the horizontal component force and the lateral force acted by the top beam of the support can be borne, the torsion resistance of the support is enhanced, and the joist is connected with a pushing jack to ensure the self-moving of the support.
