Specific embodiment
For the purpose of this utility model, technical solution and advantage is more clearly understood, below in conjunction with specific embodiment, and
Referring to the drawings, the utility model is described in further detail.
As shown in Figure 1, a kind of hydraulic support scrapes device for coal, including connecting portion 1, fixed plate 2, hydraulic cylinder 3 and with being connected
What portion 1 connected scrapes coal portion 4, and the coal portion 4 of scraping is suspended on connecting portion 1.
With reference to figure 2, the fixed part 2 is provided with the tablet of mounting hole 21 for a surface, described by the mounting hole 21
Fixed part 2 is fixedly connected with the anchor cable being anchored on back, so as to which fixed part 2 is fixed on back.It is described solid
Determine portion 2 with connecting portion 1 hingedly to coordinate.
The device for coal of scraping at least provided with a hydraulic cylinder 3,3 both ends of hydraulic cylinder respectively with fixed part 2 and
Connecting portion 1 hingedly coordinates, fixed part 2, relieve 1 and 3 triangle structure of hydraulic cylinder.It is opposite on the connecting portion 1 to set
The first clamping part 12 for being formed there are two grip block and being hinged fixed hydraulic oil cylinder 3 is put, second is correspondingly arranged on the fixed part 2
Clamping part 22 is used for the other end of hinged fixed hydraulic oil cylinder 3.In preferred embodiment, there are two the hydraulic cylinder 3, institutes for setting
It states and two the first clamping parts 12 and the second clamping part 22 is accordingly each provided on connecting portion 1 and fixed part 2.
1 bottom of connecting portion is additionally provided with an exhausting hole 11, it is described scrape coal portion 4 be fixed on by the through hole 11 it is described
On connecting portion 1, the coal portion 4 of scraping is fabricated from a flexible material, such as belt feeder conduction band, woollen blanket.
When scraping device for coal using a kind of hydraulic support provided by the utility model, hydraulic support is in the old man of fully-mechanized mining working
Side, top beam extend to coal wall side and abut back to tunnel progress gib, and the device for coal of scraping is arranged at described scrape
Device for coal, which is arranged at, to be beaten directly over wan access on top plate, and the length direction for scraping device for coal and coal wall are substantially vertical.Work
Face hydraulic support withdraw from and straightening it is parallel with coal wall after, drawing moving hydraulic support and by scraping device for coal was moved in hydraulic support
Cheng Zhong, the upper surface of hydraulic support top beam is scraped, and coal portion 4 is inswept, so as to which the waveson on top beam be disposed, prevents in follow-up liquid
There is the abnormal conditions that waveson drops in pressure stent transport process
In actual use, since the position for scraping device for coal installation is not fixed, the lower surface for scraping coal portion 4 may be caused
