Abstract
The utility model discloses a six-column type filling hydraulic support. A front beam, a front top beam and a rear top beam which are arranged from the front to the rear and are hinged together are supported by six hydraulic supports which are positioned in two rows on the base; a swing beam is hinged between the rear of the base and the rear top beam; a front connecting rod, a rear connecting rod and an upper connecting rod are additionally arranged; the lower ends of the front connecting rod and the rear connecting rod are hinged on the base; the rear connecting rod is positioned on the rear of the front connecting rod; the upper end of the front connecting rod is hinged with the front end of the upper connecting rod; the upper end of the rear connecting rod is hinged with the middle of the upper connecting rod; and the rear end of the upper connecting rod is hinged with the front top beam. According to the six-column type filling hydraulic support, the rear filling space is fully utilized, front and rear operating valves are independently operated, the front operating valve is used for descending the columns, ascending the columns, pulling the frame, pushing and guarding, the rear operating valve is used for compacting, swinging and arranging waste rock, the observation sight is good during filling, the operating space is large, the replacement and maintenance are convenient, the recovery and filling can be simultaneously performed during production, and the recovery efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of six pillar filling hydraulic supports, is used for the support of coal mining, solid filling.
Background technology
At present the form of filling mining has a lot, such as solid filling, paste body filling etc., the relatively good and instant effect of effect be solid filling, the employed capital equipment of work plane solid filling has filling hydraulic support, rear portion filling drag conveyor.The filling hydraulic support is positive four-bar linkage structure filling hydraulic support; This type is very inconvenient in the stowing operation operation; Operating personnel can only operate before frame, and sight line just can not be fine like this, and what problem the rear portion has in time to find and to shut down; Because back space is narrow and small, the maintenance of equipment etc. also there is inconvenience.
Summary of the invention
The purpose of the utility model provides a kind of six pillar filling hydraulic supports, solves that original positive four-bar linkage structure rear portion does not have the operating space and operating personnel operate bad, the unsafe defective of sight line between frame.
The purpose of the utility model realizes as follows: six hydraulic props that are in two rows through branch on the base support the hinged front-axle beam of in the past arranging backward, preceding back timber, back back timber; Hinged balance arm between base rear portion and the back back timber; Other has front rod, back link and last connecting rod; On the lower end of front rod and back link was hinged on above the base, back link was in the front rod rear portion, and the front rod upper end is hinged with last connecting rod front end; The back link upper end is hinged with last connecting rod middle part, and the rear end of last connecting rod and preceding back timber are hinged.Front rod, back link, go up the annexation between the connecting rod and constitute the reverse-four-link-bar structure with the connected mode of base, preceding back timber; This kind structure makes the filling hydraulic support; Be that enough operations and space for maintenance are all arranged before the frame or behind the frame; And the filling sight line is relatively good, and quite former positive four-bar linkage structure has very much progress.Control valve is divided into forward and backward independent operation, realizes the purpose of coal cutting, filling respectively.
The utility model has made full use of the filling space, rear portion, and control valve independent operation before and after dividing, anterior control valve are responsible for falling post, setting prop, are tried to stop people from fighting each other, pushing and sliding, wall supporting; The rear portion control valve is responsible for compacting, balance arm, is put cash; It is good to observe sight line during filling, and the operating space is big, changes easy to maintenance; Can realize that when producing back production and filling carry out simultaneously, greatly improve back production efficient.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
With reference to Fig. 1, six hydraulic props that are in two rows through branch on the base 5 support hinged front-axle beam 1, preceding back timber 2, the back back timber of in the past arranging backward 3, base 5 rear portions with after hinged balance arm 4 between the back timber 3; Other has front rod 6, back link 8 and last connecting rod 7; On the lower end of front rod 6 and back link 8 was hinged on above the base 5, back link 8 was in front rod 6 rear portions, and front rod 6 upper ends and last connecting rod 7 front ends are hinged; Back link 8 upper ends and last connecting rod 7 middle parts are hinged, and the rear end of last connecting rod 7 and preceding back timber 2 are hinged.Front rod 6, back link 8, go up the annexation between the connecting rod 7 and constitute the reverse-four-link-bar structure with the connected mode of base 5, preceding back timber 2.
Claims (1)
1. pillar filling hydraulic support; Six hydraulic props that are in two rows through branch on the base support the hinged front-axle beam of in the past arranging backward, preceding back timber, back back timber; Hinged balance arm between base rear portion and the back back timber, it is characterized in that: other has front rod (6), back link (8) and last connecting rod (7), on the lower end of front rod (6) and back link (8) is hinged on above the base (5); Back link (8) is in front rod (6) rear portion; Front rod (6) upper end is hinged with last connecting rod (7) front end, and back link (8) upper end is hinged with last connecting rod (7) middle part, and the rear end of last connecting rod (7) and preceding back timber (2) are hinged.
