Abstract

The utility model discloses a fully-mechanized hydraulic support for a steep coal face crossing fault, comprising a support base, a left top beam, a right top beam, a front connecting rod, a rear connecting rod, a shield beam, a front left upright, an upper left upright, a front right upright, a rear right upright and the like. By using the fully-mechanized hydraulic, the lifting of the left and the right top beams of the hydraulic support can be effectively controlled, the normal exploitation and safe operation of the fully-mechanized hydraulic support when a fall exists between a top plate and a bottom plate of a steep coal seam are ensured, and therefore, the fully-mechanized hydraulic support can be widely suitable for the exploitation of the steep coal seam and particularly suitable for the exploitation of the coal seam with the fall between the top plate and the bottom plate.

Description

A kind ofly be used for the comprehensive mining hydraulic bracket that the high-dipping coal-face is crossed tomography
Technical field
The utility model relates to a kind of coal mine support device, relates in particular to a kind of comprehensive mining hydraulic bracket that the high-dipping coal-face is crossed tomography that is used for.
Background technology
In the manufacturing process of high-dipping coal-face, in order to prevent the roof inbreak, keep certain working space, assurance safety of workers and operations are normally carried out, and must carry out effective support to roof.In the advance of the face process, especially pass through the both sides of tomography in the coal seam, face roof and base plate spacing are inconsistent, and the timely safety support problem of roof all is not resolved always.Comprehensive mining hydraulic bracket generally includes bracket base 1, back timber (2,3), front column (4,5), rear column (6,7), caving shield 8, front rod 9, back link 10, passes jack 11; The lower end of front rod 9 and back link 10 is hinged on the bracket base, and the lower end of caving shield 8 is hinged with the upper end of front rod 9 and back link 10 respectively, and the upper end of caving shield 8 and back timber (2,3) are hinged.When tomography was advanced in the coal seam, face roof was the zone that belongs to hazardous, and there is tangible drop in the roof and floor of tomography both sides; The back timber of hydraulic support can not contact with top board fully; The set cap part is unsettled, make set cap enough support forces not to be provided to a front column (4 or 6) and a rear column (5 or 7) that is positioned on its hanging part, so hydraulic support is easy to generate inclination; The back timber of hydraulic support and then tilts; Empty top takes place in back timber, makes back timber fully roof not to be supported fully, and the spoil that therefore is easy to cause roof is along the back timber landing; Bring danger for workman's life security, thereby influence ordinary production and have potential safety hazard.
Summary of the invention
The utility model is crossed problems such as tomography roof timbering difficulty is big, production efficiency is low, potential safety hazard height in order to solve existing hydraulic support; A kind of comprehensive mining hydraulic bracket that is used for the high-dipping coal-face is provided; This support is placed in the position that tomography is crossed in the coal seam; Let the back timber of hydraulic support fully contact the roof of effective support work plane with roof.
The utility model is to adopt following technical scheme to realize: for the technical solution problem; The utility model provides a kind of comprehensive mining hydraulic bracket that the high-dipping coal-face is crossed tomography that is used for, and comprises bracket base, left back timber, right back timber, preceding left column, back left column, preceding right column, back right column, caving shield, front rod, back link, passing jack, connects jack; Wherein, the lower end of said front rod and said back link is hinged on the said bracket base; The lower end of said caving shield is hinged with the upper end of said front and rear connecting rods respectively; One end of the upper end of said caving shield and said left and right back timber is hinged; Said left back timber connects jack with said right back timber setting, it is characterized in that: a preceding left side, a left side, back, the preceding right side, back right column are set between said left and right back timber and the said bracket base; Said left back timber and said bracket base constitute a space; Said right back timber and said bracket base constitute a space.
The beneficial effect of the utility model is: compared with prior art, back timber is left back timber and right back timber by a monoblock one-to-two; Front column and rear column are divided into a preceding left side, a left side, back, the preceding right side, back right column, and each column is connected with hydraulic power unit, can go up and down separately; When the process tomography of coal seam, bracket base is in the face of turning back, and a side of bracket base is in vacant state; This moment left side, back back timber have a side fully not contact with roof, and the forward and backward column below utilizing provides hydraulic power separately, supports left back timber and right back timber; Back timber is fully contacted with roof, guaranteed the stable of bracket base, thereby can keep roof fully to contact with back timber; Make that roof safety is more secure, protected workman's life security.

The specific embodiment
Fig. 2; A kind ofly be used for the comprehensive mining hydraulic bracket that the high-dipping coal-face is crossed tomography, comprise bracket base 1, left back timber 2, right back timber 3, preceding left column 4, back left column 5, preceding right column 6, back right column 7, caving shield 8, front rod 9, back link 10, pass jack 11, connect jack 12; A preceding left side, a left side, back, the preceding right side, back right column (4,5,6,7) are arranged between left and right back timber (2,3) and the bracket base 1, and bracket base 1 is provided with passes jack 11, and 3 of left back timber 2 and right back timbers are provided with connection jack 12.Before a left side, a back left side, the preceding right side and back right column (4,5,6,7) connect hydraulic power unit respectively separately, a preceding left side, when back left column (4,5) goes up and down, left back timber one lifting; In the time of the preceding right side, back right column (6,7) up-down, right back timber one lifting.Left side back timber 2 constitutes a space with bracket base 1; Right back timber 3 constitutes a space with bracket base 1.
The principle of the utility model: as shown in the figure, in the stope of fully-mechanized mining, particularly in the coal seam through tomography the position belong to the zone of hazardous, the work plane roof and floor is in the face of turning back.The back timber of hydraulic support (2,3) can not contact with top board fully, causes back timber (2 or 3) part to be in vacant state, makes bracket base enough support forces not to be provided to a front column (4 or 6) and a rear column (5 or 7) that is positioned on its hanging part; Bracket base is easy to generate inclination, and because the back timber part is unsettled, makes the roof collapse spoil along unsettled back timber landing; Dangerous dealing workman's life up and down; This moment, back timber was divided into left and right back timber, changed the arch mode at night of existing column, made it separately along with the independent up-down of the front column and the rear column of below; Fully contact with the top board of position of fault; On the one hand reduced the stressed of unsettled bracket base, made base keep stable on the other hand, effective support the roof of work plane.
