Abstract
The invention discloses a reliable support beam structure for a hydraulic support, and the hydraulic support applying the support beam. The hydraulic support comprises a top beam and a telescopic beam, wherein the support beam is arranged on the lower portion of the telescopic beam; the support beam is longitudinally provided with double main bars; the front ends of the double main bars form a double-lug plate; a single-lug plate is arranged on the front portion of the telescopic beam; the double-lug plate is hinged with the single-lug plate. According to the reliable support beam structure and the hydraulic support, the strength of a hinge hole which is liable to break due to pulling during use is greatly enhanced, and the telescopic beam is provided with an enough space capable of realizing a thick design of the single-lug plate participating in hinge, thus ensuring no breakage due to pulling.
Description
Technical field
The present invention relates to a kind of coal-mine hydraulic support, relate in particular to a kind of reliability joist structure and hydraulic support of hydraulic support.
Background technology
Hydraulic support is as a kind of coal mine fully-mechanized mining working support apparatus, and many type back timber front portions are provided with flexible side protecting mechanism, one of important component part of joist Shi Gai mechanism, and it mainly plays the effect of carrying wall supporting jack.
Joist structure of the prior art, adopts the ears plate of single main muscle otic placode and extensible canopy hinged, in use, when the easy wall caving of working face wall, particularly floor undulation longitudinally has inclination angle, support to face upward while adopting, and the hinged ear of joist and extensible canopy is usually drawn open-minded, and is difficult to change, keep in repair.Meanwhile, affected by space structures, joist cannot improve self intensity by hinged thickness of slab by larger increase.
Summary of the invention
The reliability joist structure of the hydraulic support of the object of this invention is to provide that a kind of intensity is high, the life-span is long and apply the hydraulic support of this kind of joist.
The object of the invention is to be achieved through the following technical solutions:
The reliability joist structure of hydraulic support of the present invention, this hydraulic support comprises back timber, extensible canopy, the bottom of described extensible canopy is provided with joist, described joist is longitudinally provided with two main muscle, the front end of described two main muscle forms ears plate, the front portion of described extensible canopy is provided with monaural plate, and described ears plate and described monaural plate are hinged.
Hydraulic support of the present invention, described hydraulic support is provided with the reliability joist structure of above-mentioned hydraulic support.
As seen from the above technical solution provided by the invention, the reliability joist structure of the hydraulic support that the embodiment of the present invention provides and apply the hydraulic support of this kind of joist, owing to adopting, two main muscle otic placodes and extensible canopy are hinged, greatly improved in use and easily drawn open-minded hinge hole intensity, the extensible canopy of answering in contrast adopts monaural plate, extensible canopy has enough spaces by participating in the thicker of hinged monaural plate design, to guarantee not drawn open-minded.

The specific embodiment
To be described in further detail the embodiment of the present invention below.
The reliability joist structure of hydraulic support of the present invention, its preferably the specific embodiment be:
This hydraulic support comprises back timber, extensible canopy, and the bottom of described extensible canopy is provided with joist, and described joist is longitudinally provided with two main muscle, and the front end of described two main muscle forms ears plate, and the front portion of described extensible canopy is provided with monaural plate, and described ears plate and described monaural plate are hinged.
Described joist is longitudinally provided with two groups of two main muscle, and the front end of described two groups of two main muscle forms two groups of ears plates, and the front portion of described extensible canopy is provided with two monaural plates, and described two groups of ears plates are hinged with described two monaural plates respectively.
The rear portion of two main muscle that the inner side of described two groups of two main muscle is leaned on mutually forms one group of ears plate, and the cylinder bottom of this group ears plate and backplate jack is hinged.
Hydraulic support of the present invention, its preferably the specific embodiment be:
Described hydraulic support is provided with the reliability joist structure of above-mentioned hydraulic support.
Described hydraulic support is two column protected type hydraulic support or four post support shield type hydraulic support.
Specific embodiment:
Reliability joist structure is as shown in Fig. 1 a, 1b, Fig. 2 a, Fig. 2 b, Fig. 3, and joist is provided with main muscle 1-1,1-2,2-1,2-2, forms two groups of two hinged ears, hinged with two monaural plates 9 of extensible canopy 5 front portions.Because joist structure adopts ears plate, corresponding extensible canopy, adopt monaural plate, greatly improved the intensity of the hinged ear of joist, simultaneous retractable beam has enough spaces by participating in the thicker of hinged monaural plate design, to guarantee not drawn open-minded.
As shown in Fig. 2 b, Fig. 3, pin joint Q and the joist 4 of extensible canopy 5 are hinged, as can be seen, for coordinating the ears plate of joist 4 hinged, corresponding extensible canopy place is monaural plate, and design space abundance, that this otic placode can be designed is thicker, even if be therefore monaural, also possess enough tensile strength, guarantee that hinge hole can not drawn open-minded.
As shown in Figure 4, the hydraulic support of applying above-mentioned joist comprises face guard 1, wide bar 2, narrow bar 3, joist 4, extensible canopy 5, flexible jack 6, wall supporting jack 7, back timber 8 etc.Extensible canopy 5 is placed in back timber 8 inside, and joist 4 is below back timber 8, extensible canopy 5, and hinged with extensible canopy 5 front portions by two groups of main muscle otic placodes.Face guard 1 is hinged with the front end of extensible canopy 5, one end of wide bar 2 and narrow bar 3 is hinged with face guard 1 and extensible canopy 5 respectively, together with the front end three of the other end of wide bar 2 and narrow bar 3 and wall supporting jack 7 piston rods is point articulated, the cylinder bottom of wall supporting jack 7 and joist 4 are hinged, control face guard and realize 180 ° of upsets.The joist 4 hinged wall supporting jack 7 cylinder bottom ends in rear portion, slide with extensible canopy 5 with wall supporting jack 7.The piston rod of flexible jack 6 with extensible canopy 5 is hinged, cylinder bottom and back timber 8 hinged, the stretching out and regain of control extensible canopy 5 and whole flexible wall supporting structure.
In above-described embodiment, wall supporting jack 7 quantity are 1, in practical application, can be designed to as required 1 or two, and wide bar, narrow bar quantity depend on wall supporting jack quantity.The hydraulic support of above-described embodiment is two column protected type, in practical application, can be both two column protected type hydraulic support, can be also four post support shield type hydraulic support etc., as long as support can be applied joist structure of the present invention with flexible side protecting mechanism.
The above; only for the preferably specific embodiment of the present invention, but protection scope of the present invention is not limited to this, is anyly familiar with in technical scope that those skilled in the art disclose in the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
