Description
Technical field
The utility model relates to a kind of comprehensive mining hydraulic bracket that is used for coal-face supporting roof under the coal mine.
Background technology
Hydraulic support divides comprehensive mining hydraulic bracket and hydraulic prop for sliding mine caps two big classes, comprehensive mining hydraulic bracket good stability wherein, and it is fast to move frame, and its outstanding characteristics are the walkings of standing voluntarily when moving frame.Comprehensive mining hydraulic bracket comprises integral top beam or whole articulated roof beam, chassis, moves frame mechanism, is located at the height-regulating mechanism between back timber and the chassis at the hydraulic prop between integral top beam and the chassis, by what move that frame cylinder and push rod form, and height-regulating mechanism mainly is divided into four-bar mechanism, single wobbling pole mechanism and three kinds of forms of perpendicular guide rail mechanism.Comprise caving shield in some height-regulating mechanism, beam and caving device for coal before some comprehensive mining hydraulic bracket also comprises.Prior art in this field has hydraulic chock-shield support, hydraulic shield support and standing shield hydraulic support three major types by the form of structure branch.Wherein hydraulic chock-shield support is four pillars with standing shield hydraulic support and is connected back timber and chassis, and front and back are respectively arranged two; What hydraulic shield support had four pillars also has transversely arranged two pillars.No matter be which kind of form, all be that the chassis of support is very wide at support two pillars that transversely are arranged side by side.For example the Coal Industry Press mentions in " top coal caving technology and caving roof coal hydraulic support " book of nineteen ninety-five publication, the support model of being produced by the design of Zhengzhou coal machine factory is: " caving roof coal hydraulic support " of ZFS5200/17/35, (unit: be 5800 * 1600 * 1700 millimeter), its carriage center distance is 1.6 meters to its delivery profile size; Grinding the support model that designed, Zhengzhou coal machine factory produces by the Shenyang coal is: " caving roof coal hydraulic support " of YFY200-16/26, (unit: be 3550 * 1500 * 1600 millimeter), its carriage center is apart from being 1.5 meters or the like for its delivery profile size.The well type is little often for present some old ore deposit, medium and small colliery and the relatively poor colliery of geological conditions, and the tunnel is narrow, and is quite difficult to the transportation of large-scale comprehensive mining hydraulic bracket, even can't transport at all.Like this, just make applying of comprehensive mining hydraulic bracket be subjected to influence.
