Abstract
The utility model relates to a support device of a mine coal working face and two gates, in particular to an inverted four-link hydraulic bracket which solves the problem that the space under the traditional hydraulic bracket is small. The hydraulic bracket is provided with a pedestal, a sloped beam, a front connecting rod, a back connecting rod and a top beam. The sloped beam is articulated on the pedestal. The front connecting rod and the back connecting rod are respectively articulated between the sloped beam and the top beam to form an inverted four-link mechanism. The hydraulic bracket uses a sloped beam to replace a shield beam of the traditional bracket, inverts the four-link mechanism, uses the space above the top beam reasonably, saves the space of the pedestal correspondingly and can provide safe wide pedestrian space under the bracket and the installation space of relative equipments.
Description
Technical field
The utility model relates to the support apparatus of coal mine work area and two crossheadings, is specially a kind of inversion four connecting rod hydraulic supports.
Background technology
What at present, the motion of hydraulic support adopted all is just to put quadric chain.The quadric chain of just putting is that back timber and caving shield upper end single-point is hinged, and caving shield lower end and front and rear connecting rods upper end are hinged respectively, the mode that front and rear connecting rods lower end and base are hinged.Because base connected front and rear connecting rods, the remaining space of base is narrow and small, makes the installing space deficiency of people's row space and relevant device.
The utility model content
The purpose of this utility model is to provide a kind of inversion four connecting rod hydraulic supports, solved the narrow and small problem in space under the conventional hydraulic support frame, by quadric chain is inverted, make that the space increases under the frame, the safe and spacious frame servant row space and the installing space of relevant device can be provided.
The technical solution of the utility model is:
A kind of inversion four connecting rod hydraulic supports, this hydraulic support is provided with base, cant beam, front rod, back link, back timber, column, cant beam is hinged on the base, front rod, back link are hinged on respectively between cant beam and the back timber, form inverted quadric chain, the column two ends are articulated in base and back timber respectively.
Described inversion four connecting rod hydraulic supports, front rod, back link upper end and back timber are hinged, and front rod, back link lower end and cant beam are hinged, and cant beam lower end and base are hinged.
The beneficial effects of the utility model are:
1, the utility model is inverted four connecting rod hydraulic supports and is constituted by base, cant beam, front rod, back link, back timber, column etc. are mutually hinged, compares with the conventional hydraulic support, adopts a cant beam to replace the caving shield of conventional stent, and quadric chain is inverted in the frame.Be that the front and rear connecting rods upper end is hinged with back timber, front and rear connecting rods lower end and cant beam are hinged, and cant beam lower end and base are hinged, and column is articulated between base and the back timber.The utility model is inverted quadric chain, has utilized the space on the back timber effective and reasonablely, and the corresponding base space of having saved provides the spacious frame servant row space of safety and the installing space of relevant device.
2, the utility model can be used for the elevating movement mechanism of work plane middle frame, work plane transition frame, face end frame and two crossheading advance support racks.
Description of drawings
Fig. 1 is for being inverted four connecting rod hydraulic rack structure schematic diagrames.
Fig. 2 is for being inverted four connecting rod hydraulic supports at work plane lower end supporting schematic diagram.
Among the figure, 1 base; 2 columns; 3 cant beams; 4 front rods; 5 back links; 6 back timbers; 7 elevating conveyors; 8 hydraulic supports; 9 people's row spaces; 10 scratch board conveyors.
The specific embodiment
Below in conjunction with accompanying drawing and example the utility model is further specified.
As shown in Figure 1, the utility model is inverted four connecting rod hydraulic supports and is constituted by base 1, column 2, cant beam 3, front rod 4, back link 5, back timber 6 etc. are mutually hinged, cant beam 3 is hinged on the base 1, front rod 4, back link 5 are hinged on respectively between cant beam 3 and the back timber 6, form inverted quadric chain.Concrete structure is as follows:
Front rod 4, back link 5 upper ends and back timber 6 are hinged, and front rod 4, back link 5 lower ends and cant beam 6 are hinged, and cant beam 3 lower ends and base 1 are hinged, and column 2 two ends are articulated in base 1 and back timber 6 respectively.
As shown in Figure 2, for being inverted four connecting rod hydraulic supports in work plane lower end supporting operating mode, on drag conveyor 10 mounting seat 1, elevating conveyor 7 is installed in the medium position of base 1.Because hydraulic support 8 moves on to support top with front rod 4, back link 5, base 1 only is connected with cant beam 3, and hydraulic support 8 not only provides the safety work space for elevating conveyor 7 and drag conveyor 10, and broader frame servant row space 9 also is provided.
The course of work of the present utility model is: column 2 provides the lifting power of hydraulic support 8, realizes the curve movement and the kinetic stability thereof of hydraulic support 8 by inverted quadric chain.
Claims (2)
1. be inverted four connecting rod hydraulic supports for one kind, it is characterized in that: this hydraulic support is provided with base, cant beam, front rod, back link, back timber, column, cant beam is hinged on the base, front rod, back link are hinged on respectively between cant beam and the back timber, form inverted quadric chain, the column two ends are articulated in base and back timber respectively.
2. according to the described inversion four connecting rod hydraulic supports of claim 1, it is characterized in that: front rod, back link upper end and back timber are hinged, and front rod, back link lower end and cant beam are hinged, and cant beam lower end and base are hinged.
