Abstract
The utility model discloses a kind of caving coal support breaker, the caving coal support is equipped with the tail-boom, set up cylinder footpath for phi 160 mm's broken jack on the tail-boom, be equipped with switching-over valve and individual valve on broken very heavy hydraulic pressure pipeline, strengthened the support and scraped the crushing ability of the board machine and go up great coal cinder to the rear portion, reduced the destruction of rear portion bold coal to tail-boom mechanism department rubber tube and jack piston rod.
Description
Technical Field
The utility model relates to an kind caving coal supports especially relate to kind caving coal support breaker.
Background
At present, the hydraulic support structure for caving top coal at home and abroad adopts the conventional design, a tail beam flashboard mechanism is connected behind a shield beam, the tail beam flashboard not only can realize a coal caving base, but also has the function of crushing a larger coal briquette on a rear scraper, however, due to the problems of height limitation of a beam body and the like, the cylinder diameter of a flashboard jack is phi 80 mm-phi 125mm, and the crushing capacity is .
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an kind of caving coal support breaker.
The utility model aims at realizing through the following technical scheme:
the utility model discloses a caving coal support breaker, the caving coal support is equipped with the tail boom, set up broken jack on the tail boom.
By the foregoing the utility model provides a technical scheme can see out, the embodiment of the utility model provides a caving coal support breaker has strengthened the support and has scraped the crushing ability of the board machine of scraping last great coal cinder to the rear portion.
Drawings
Fig. 1 is a schematic structural view of a crushing device for a caving coal support provided by the embodiment of the utility model.
In the figure: 1. and (5) crushing the jack.
Detailed Description
The embodiments of the present invention will be described in further detail below in , and those embodiments of the present invention that are not described in detail are within the skill of those in the art.
The utility model discloses a caving coal support breaker, the concrete implementation mode of its preferred is:
the caving coal support is provided with a tail beam, and crushing jacks are arranged on the tail beam.
A reversing valve is arranged on a hydraulic pipeline of the breaking jack, and a check valve is arranged on a lower cavity hydraulic pipeline of the breaking jack.
The cylinder diameter of the crushing jack is phi 160 mm.
The utility model discloses a top coal caving support breaker has strengthened the support and has scraped the crushing ability of the board machine of scraping the board and go up great coal cinder to the rear portion.
The specific embodiment is as follows:
as shown in figure 1, crushing jacks with the cylinder diameter of 160mm are arranged on a tail beam, when a rear scraper has large coal blocks, the crushing jacks can be operated to crush the large coal blocks, each crushing jack is provided with one-way valves to prevent the crushing jack from automatically extending due to gravity to influence the rear coal block passing, in addition, the jacks are controlled to act through reversing valves, when the coal blocks need to be crushed, the reversing valves are controlled to feed liquid into the lower cavities of the jacks, the crushing jacks extend out to crush the large coal blocks, and after the crushing is finished, the reversing valves are controlled to feed liquid into the upper cavities of the jacks, and the crushing jacks are retracted.
The utility model discloses can strengthen the crushing ability of caving coal hydraulic support to the rear portion scraper blade machine lump coal, reduce the destruction of rear portion lump coal to tail boom mechanism department rubber tube and jack piston rod.
The above description is only for the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are all covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
