Abstract
The utility model discloses a self-advancing advance timbering hydraulic support in a roadway. The hydraulic support comprises a front supporting frame and a rear supporting frame, the front and rear supporting frames which have the same structures and are longitudinally arranged along the roadway are connected via a pushing jack, the front and rear supporting frames respectively comprise a base, two main vertical posts and two auxiliary vertical posts, the vertical posts are all arranged on the base, a top beam is arranged on the main vertical posts, the upper surface of the top beam is a cambered surface corresponding to the top of the roadway, axes of the main vertical posts are coincided with the vertical center line of a section of the roadway, a rear end of the top beam is hinged with the end of a shield beam, the lower portion of the shield beam is hinged with the base via a connecting rod, and the top ends of the auxiliary vertical posts are hinged with the upper portion of the shield beam. The self-advancing advance timbering hydraulic support has the advantages that the shape of the top beam matches with that of the circular or elliptical top of the roadway, thereby generating strong supporting capacity. When in situations of roof weighting or generating bottom heaves, life safety of operators on extraction working faces and smoothness of upper and down crossheadings can be guaranteed, thereby keeping production on the extraction working faces normal.
Description
Technical field
The utility model relates to the colliery hydraulic support, especially relates to a kind of automatic moving type tunnel advance support hydraulic support.
Background technology
China is one of country of coal seam reserves maximum in the world, and fully-mechanized mining working quantity constantly increases, and particularly the work plane of high-yield and high-efficiency is increasing.According to the geological conditions of stope working surface of coal mines, the section in some tunnel is circular or oval, and existing forepoling hydraulic support top all is the plane, can't guarantee the requirement in circle or oval tunnel.
The utility model content
The purpose of this utility model is to provide a kind of advance support requirement that not only can satisfy circle or oval tunnel, and can guarantee the automatic moving type tunnel advance support hydraulic support of the unimpeded and work plane personal security in the coal face advance support scope.
For achieving the above object, the utility model can be taked following technical proposals:
Automatic moving type tunnel advance support hydraulic support described in the utility model, it comprise along the tunnel vertically be provided with, back and front supporting frame that structure is identical, be connected by passing jack between the described back and front supporting frame; Described back and front supporting frame includes: base and two head trees and two secondary columns of being arranged on the described base, and described head tree is provided with back timber, and described back timber upper surface is and the corresponding globoidal structure in top, tunnel; The axis of described head tree and the vertical center line of drift section coincide; Described top beam rear end and caving shield top ends are hinged; Described caving shield bottom is hinged by connecting rod and described base; Described secondary column top and caving shield top are hinged.
Between described back and front supporting frame, be provided with outrigger, be provided with the connection otic placode in described outrigger rear end, described connection otic placode middle part is hinged with the back timber sidewall of rear support stand, connects the otic placode lower end and is connected by the engaging lug of jack with the back timber soffit of rear support stand.
Advantage of the present utility model is that back timber shape and circular or top, oval tunnel adapt, and have powerful support capacity.At roof weighting with go out terrain when drum, can guarantee stope staff's life security and crossheading unobstructed up and down, back production is looked unfamiliar produce normally.When needs moved certainly, front support stand landed in the work, and rear support stand supports, and promoted front support stand by the thrust of passing jack and made its reach; Front support stand supports the rear support stand landing then, by the pulling force pulling rear support stand of passing jack it is advanced, and supporting roof is risen in the back that puts in place, moves certainly and finishes.The center line of head tree overlaps with vertical maximum gauge in circular or oval tunnel, supports the most stable; Back timber, caving shield support by head tree and secondary column, and base plate is born the pressure that the top is transmitted, and guarantees normal working space; The quadric chain of caving shield lower hinge prevents that in order to guarantee the stability of bracing frame the spoil that falls from entering in the tunnel.Between described back and front supporting frame, be provided with outrigger, be provided with the connection otic placode at described outrigger one end, back timber one end that connects otic placode middle part and rear support stand is hinged, connecting the otic placode bottom is connected with the back timber below of rear support stand by jack, guaranteed the safety between the back and front supporting frame, effectively protected the spoil whereabouts personnel etc. are damaged.
Description of drawings
