Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As depicted in figs. 1 and 2, a kind of coal mining machine supporting device, comprise and support overcoat 1, support inner sleeve 2, coal scraper plate 3, road wheel 5, cowl 6, hydraulic cylinder 7, wheel carrier 8 and obliquity sensor, the upper end of described support overcoat 1 is connected with coal-winning machine fuselage; The upper end of described support inner sleeve 2 is sleeved on the lower end supporting overcoat 1 slidably, realizes the support protective effect of coal-winning machine; Described hydraulic cylinder 7 is arranged on and supports overcoat 1 and support in space that inner sleeve 2 formed, and two ends are connected with the lower end supporting inner sleeve 2 with the upper end of support overcoat 1 respectively; The lower end of described support inner sleeve 2 is fixedly connected on wheel carrier 8, and wheel carrier 8 is installed with axle 10, realizes the support to road wheel 5 and constraint, road wheel 5 is connected on axle 10 by bearing, thus realizes the rotation of road wheel 5 on axle 10; Described obliquity sensor is installed on any part except road wheel 5, support overcoat 1 inside wall and cowl 6 inwall, described obliquity sensor is connected with controller by the signal of telecommunication, described controller is connected with hydraulic cylinder 7, obliquity sensor by the signal feedback that detects to controller, controller sends control signal to hydraulic cylinder 7, can be regulated the height of this bracing or strutting arrangement by the cooperation between obliquity sensor and hydraulic cylinder 7, thus it is inconsistent and cause turning on one's side or the wearing and tearing of aggravation guide sliding shoe of coal-winning machine to avoid height due to coal mining machine rail both sides; The upper end of described coal scraper plate 3 is fixed on wheel carrier 8, gap is there is between lower end and track 4, the lower end of described coal scraper plate 3 tilts to the direction away from road wheel 5, thus the cleaning realized cinder on track 4, prevent coal from piling up and making the height of coal mining machine rail 4 both sides inconsistent, cause the wearing and tearing turning on one's side or aggravate guide sliding shoe of coal-winning machine; Described cowl 6 is fixedly connected on coal scraper plate 3, the opening direction of described cowl 6 is consistent with the incline direction of coal scraper plate 3, thus the coal effectively removed lower than scratch board conveyor transportation surface, eliminate coal to pile up the stop caused during drag conveyor pushing and sliding, coal mining face is moved efficiently.
In order to make obliquity sensor can not be damaged in coal-winning machine operation, described obliquity sensor is installed on the inside wall of support inner sleeve 2.
In order to make coal scraper plate 3 more effectively can clean out coal on track 4, the lower end of described coal scraper plate 3 is 30 ° ~ 60 ° to the angle of inclination, direction away from road wheel 5.
In order to make coal scraper plate 3 more effectively can clean out coal on track 4, the gap existed between the lower end of described coal scraper plate 3 and track 4 is 0.5cm ~ 1cm.
In order to prevent the rotation of axle 10, described axle 10 is fixedly installed on wheel carrier 8 by pressing plate 9.
During use, the present invention is installed on respectively four ends below coal-winning machine, track 4 is installed on drag conveyor and is fixed, for the walking of coal-winning machine provides track.When the normal coal work of coal-winning machine, coal-winning machine adopts cylinder coal cutting, when the coal cut off is fallen on coal mining machine rail 4, in the process that coal scraper plate 3 is walked at coal-winning machine, the coal on track 4 is cleared up, simultaneously, cowl 6 also carries out auxiliary coalingging along with the movement of coal-winning machine, coordinates the height regulating this bracing or strutting arrangement between obliquity sensor and hydraulic cylinder 7, thus it is inconsistent and cause turning on one's side or the wearing and tearing of aggravation guide sliding shoe of coal-winning machine to avoid height due to coal mining machine rail both sides; In the present invention, road wheel 10 and track 4 Relative friction are rolling friction, effectively can reduce the frictional force between road wheel and track, reduce the running resistance of coal-winning machine; In addition, adopt the frictional dissipation of rolling friction to road wheel 10 less, support relative to traditional dull and stereotyped piston shoes, the number of times of maintenance and replacing road wheel can be reduced, extend the application life of equipment, improve the output of coal-winning machine and the economic benefit in colliery.
As shown in Figure 3, described four bracing or strutting arrangements are labeled as A respectively, B, C, D, wherein A, B is parallel one group, C, D is parallel one group, in figure, the height of B point and D point is constant, when A point or C point too high or too low time, the inclination angle between AB and CD 2 is detected respectively by obliquity sensor, then the data collected are passed to MCU microcontroller and carry out logical decision by obliquity sensor, whether within the limits prescribed to judge same group of inclination angle, if exceeded the inclination angle scope of regulation, then MCU microcontroller sends order to hydraulic cylinder 7, hydraulic cylinder 7 is by instruction lifting, drive to support overcoat 1 and support inner sleeve 2 and be elevated thereupon, the height of adjustment A point or C point, thus make the inclination angle scope of same group reach in the scope of regulation, prevent coal-winning machine from occurring that the phenomenon that rollover or aggravation guide slip shoe wear and tear occurs because orbit altitude difference in both sides is excessive.
