Abstract
The invention relates to a sub-frame support device. The sub-frame support device is hinged with a middle groove of a reversed loader through pins. A support cylinder is hinged with a base seat and a support beam, wherein the support beam adopts a segmental structure, is hinged by connecting rods, and further adopts a joist steel overall welding structure. A sub-frame top beam is welded in butt welding mode by two joist steels, and reinforcing plates are additionally welded above and below the sub-frame top beam so as to improve overall strength of the top beam. The base seat adopts a steel plate box structure, and is connected with the middle groove of the reversed loader in hinge mode and arranged according to the need that front and rear squeegee machines are matched with the reversed loader. A hydraulic system uses working face high pressure emulsion as a power source, completes lifting of a sub-frame through an operating valve set, a high pressure pipeline, a hydraulic control one-way valve and a lifting jack, and therefore achieves management of a top plate.
Description
Technical field
The present invention relates to colliery low caving coal fully-mechanized mining working and combine a kind of real-time suspension device of head region Roof Control.
Background technology
Coal mine fully-mechanized mining working much adopts the low caving coal process for stoping, uses ZFS6000/17/33 type hydraulic support ZT6500/19.5/34 type crab bearer that face roof is managed, the use of file leader's frame, and successful face end support moves difficult problem.But in production practices, owing to adopt for no reason headstock support pattern, when moving crab bearer, the large plate that is supported on file leader's frame back timber and the front-axle beam descends with support is whole, causes the end regions top board to descend.When roof cracking or pressure were large, the slippage of top board was just very large, badly influences the end regions roof control.Simultaneously, there is certain potential safety hazard in the personnel that enter the Delta Region operation.
Summary of the invention
The subframe suspension device that the purpose of this invention is to provide a kind of real-time control end head region top board.
The present invention is according to fully-mechanized mining working faces end head support pattern and coordinative composition of equipments situation, taking full advantage of the self-moving reversed loader section of landing is section's groove structure, develop the reliable subframe suspension device of a cover, be fixed on the elevating conveyor section of landing and the supporting place of front and back drag conveyor, utilize the work plane high-pressure emulsion to operate as power source, with the elevating conveyor integral forward lead, cooperate crab bearer, finish the real-time supporting in plate zone, the crown, opposite end.
Subframe suspension device of the present invention and elevating conveyor intermediate channel adopt bearing pin hinged, and supporting oil cylinder and base, supporting beam adopt articulated manner, and supporting beam adopts the structure that paragraphs, and rod hinge connection, supporting beam adopt worker's steel integral solder structure.
Wherein, the subframe back timber is selected two i iron butt welding, and reaches in the above following repair welding stiffener, to improve the bulk strength of back timber.Base adopts the container body of steel plate structure, adopts articulated manner to connect with the elevating conveyor section of landing intermediate channel, according to front and back scrapper conveyor and the supporting requirement of elevating conveyor, arranges 3 of bases.
Hydraulic system utilizes the work plane high-pressure emulsion as power source, through operating valve group, pressure duct, hydraulic control one-way valve and jack, finishes the lifting work of subframe, realizes the management to top board.
Subframe suspension device of the present invention can be adjusted according to the supporting situation of fully-mechanized mining equipment, device structure form, roof pressure situation, have the characteristics such as simple in structure, practical, simple to operate, respond well, but realized the board management mechanization of the crown, opposite end, eliminate the potential safety hazard of workman when the operation of trigonum, reached designing requirement.
This device can all low companion's caving fully mechanized face end regions be installed and used in the colliery, has widely dissemination.
Description of drawings
Fig. 1 is structural representation of the present invention.
Specific embodiments
According to fully-mechanized mining working faces end head support pattern and coordinative composition of equipments situation, taking full advantage of the self-moving reversed loader section of landing is section's groove structure, design subframe suspension device shown in Figure 1, be fixed on the elevating conveyor section of landing and the supporting place of front and back drag conveyor, utilize the work plane high-pressure emulsion to operate as power source, with the elevating conveyor integral forward lead, cooperate crab bearer, finish the real-time supporting in plate zone, the crown, opposite end.
Back timber 5 is selected the butt welding of two 11# i iron, and reaches in the above following repair welding stiffener, to improve the bulk strength of back timber.Base 4 adopts the container body of steel plate structure, adopts articulated manner to connect with the elevating conveyor section of landing intermediate channel 2, arranges base according to front and back scrapper conveyor and the supporting requirement of elevating conveyor.
Hydraulic system utilizes the work plane high-pressure emulsion as power source, through operating valve group, pressure duct, hydraulic control one-way valve and supporting oil cylinder 3, finishes the lifting work of subframe seat 1, realizes the management to top board.
Claims (2)
1. the subframe suspension device is characterized in that adopting bearing pin hinged with the elevating conveyor intermediate channel, and supporting oil cylinder and base, supporting beam adopt articulated manner, and supporting beam adopts the structure that paragraphs, and rod hinge connection, supporting beam adopt worker's steel integral solder structure.
2. subframe suspension device according to claim 1, it is characterized in that on the subframe back timber and below the repair welding stiffener.
