Abstract
The present invention discloses a hydraulic support for tunnel digging working face, which comprises a main frame and an auxiliary frame; the main frame is composed of two bar-shaped and U-shaped main frame bases which are provided with intervals in parallel, telescopic hydraulic upright posts which are respectively vertically arranged along the axial direction of the main frame bases, main frame top beams arranged at the top ends of the hydraulic upright posts, and beams arranged on the main frame top beams; the beams are provided with a plurality of shed beams which are parallel with the main frame top beam; the U-shaped forks of the two main frame bases are respectively provided with bar-shaped auxiliary frame bases, the auxiliary frame hydraulic upright posts which are vertically arranged along the axial direction, and auxiliary frame top beams arranged at the top ends of the auxiliary frame hydraulic upright posts in a movable fit way; the main frame bases and the front ends of the auxiliary frame bases are hinged through a process jack. As the utility model adopts the structure characteristics, the purpose that workers can safely work under a frame which is composed of the main frame top beams, the shed beams and the auxiliary frame top beams can be realized, and the work efficiency of the tunnel driving is greatly improved.
Description
Technical field:
The present invention relates to coal digging field, particularly relate to the hydraulic support that is used for roadway head.
Background technology:
The preparation of coal-face at first will be opened up upper and lower crossheading and open-off cut, Coal Transport and vent passages is provided for the exploitation work plane.At present, the tunnel is when headwork, and its driving face does not protect ceiling or other protective equipment, because the width in tunnel is generally all about 4 meters, make that the work plane top brings threat for staff's life and national wealth at any time all by the possibility of subsiding when driving.U.S. Patent number is: US4048804A discloses a kind of support apparatus of digging up mine and using, though this support apparatus has taked separate type to connect the base at the end, but it mainly is the horizontal scrambling that can adapt to base plate in order to ensure support apparatus when working, still unresolved driving face top protection problem.
Summary of the invention:
The present invention's purpose is to provide a kind of hydraulic support that is used for roadway head at above-mentioned existing in prior technology deficiency.
For achieving the above object, the present invention can be achieved through the following technical solutions:
The hydraulic support that is used for roadway head of the present invention comprises body frame and subframe; Two stripe U type body frame bases that described body frame is provided with at interval by being parallel to each other, along described body frame datum axle to vertically disposed telescopic hydraulic vertical prop respectively, with the body frame back timber that is arranged on described hydraulic vertical prop top, and the crossbeam that is arranged on the described body frame back timber is formed; On described crossbeam, be parallel to the body frame back timber and be provided with many capplces; In two body frame base U-shaped prongs, be respectively arranged with bar shaped subframe base and distinguish vertically disposed subframe hydraulic vertical prop vertically in mode movingly, and the subframe back timber that is arranged on subframe hydraulic vertical prop top; The leading section of described body frame base and subframe base is hinged by passing jack.
For ease of the laying operation of anchor net, anchor band, be hinged with outrigger by jack respectively at the front end of described body frame back timber, capplce and subframe back timber.
In order to guarantee the stability of support, be hinged by fork respectively between described body frame base and corresponding with it body frame back timber, subframe base and the corresponding with it subframe back timber.
The present invention makes the staff when tunnelling owing to adopt the said structure feature, can be under the frame that constitutes by described body frame back timber, capplce and subframe back timber safety carry out tunnelling and anchor net, anchor band are laid operation.And, realize moving forward and backward of hydraulic support of the present invention by the passing jack that is arranged on body frame base and subframe base leading section with major and minor support fulcrum each other, improved the operating efficiency of tunnelling widely.
