Description
Technical field
The invention belongs to technical field of coal mine equipment, in particular to a kind of top beam and the hydraulic support comprising the top beam.
Background technique
Coal mine fully-mechanized mining working carries out supporting using hydraulic support, and hydraulic support is that working face safe working creates well
Operating environment.Hydraulic support frame hinging beam is mainly fixed using pin shaft at present, and there are two main portions: first is that installation dimension
Greatly, besides bearing capacity is limited, if reducing the structure size of hinged girder, while improving its bearing capacity, is that hinged girder must
It need solve the problems, such as.
A kind of patent (ZL 95228313.1) hydraulic articulated cap is equipped with two pieces of hinged ears or side handles of a utensil, beam hinged by pin shaft
Hydraulic jack is arranged below in body, which has two, first is that the installation fixation of hydraulic jack occupies biggish sky
Between, besides the effect of hydraulic jack is effective, articulated roof beam to deposit loading capability limited.
A kind of radial type top beam of patent (201220362500.6), preceding top beam and middle part top beam are hinged by pin shaft, sinciput
Beam has the dip section for protruding into middle part top beam, is hinged with the briquetting being pressed against on dip section on the top beam of middle part, briquetting passes through connecting rod
It is connect with bolumn cap, which has two: first is that be that bearing capacity is limited, since bolumn cap is connect by connecting rod with briquetting,
It can be moved forward and backward, bearing capacity depends primarily on the bearing strength of connecting rod；Second is that briquetting is easy stress deformation, briquetting is with before
The way of contact of top beam often changes, it is difficult to and briquetting is effectively ensured and preceding top beam is face contact, when the two is that line contacts, contact
Face load is larger, and briquetting regional area is easy stress deformation.
To overcome the shortcomings of above-mentioned technology, a kind of under the precondition for guaranteeing hydraulic support strength and stiffness, energy is needed
Enough methods for effectively mitigating hydraulic Zhi Chongliang.
Summary of the invention
The purpose of the present invention is the mines and thin seam working surface that have higher requirements for Coal Transportation size to provide a kind of indulge
The hinged girder construction small to cross dimensions, using hinged girder and main canopy case nested structure, by inserting main canopy front end cabinet
Enter in the cavity of hinged girder, solves the problems, such as that current hinged girder front end support top power is small, installation dimension is excessive.
Technical solution: the rear end of hinged girder is set chamber by a kind of top beam of the present invention and the hydraulic support comprising the top beam
Body structure, main canopy front end are set as body structure, and main canopy end cabinet is extend into hinged girder cavity, hinged girder and main canopy
It is connected as the beam structure with stronger bearing capacity by closing piece, efficiently solves existing hinged girder girder construction ruler
Very little big, the limited problem of bearing capacity.
Front and back two parts are divided by transverse bar plate hinged girder in the middle part of hinged girder of the invention, the front of transverse bar plate is cabinet knot
Structure improves top beam front end support top power；The rear of transverse bar plate forms cavity body structure, hinged girder cavity by two vertical gussets and web
The stronger composite box structure of bearing capacity is formed with the cabinet of main canopy, to improve the bearing capacity of hinged girder.
Web two sides below hinged girder cavity of the invention are equipped with wrapper sheet, and as hinged load bearing beam, wrapper sheet is by hinged girder
Longitudinal gusset and web be linked to be an entirety, avoid hinged girder longitudinal gusset and web because weld seam due to large carrying capacity
Cracking, effectively enhances hinged girder construction.
Hinged girder and main canopy of the invention is fixed by closing piece, and closing piece is passed through hinged girder and main canopy when installation
On lockhole, then limited with lock pin, it is easy to disassemble, it is easy for installation.
The present invention solves the problems, such as that current hinged girder front end support top power is small, installation dimension is excessive, effectively improves top
Joist support loading capability provides a kind of good method and technological approaches for the design of hydraulic support frame hinging beam.
Present invention tool has the advantage that.
(1) structure is simple, easy for installation, using hinged girder and main canopy case nested structure, by by main canopy head end box
Body is inserted into the cavity of hinged girder, fixed by closing piece.
(2) structure size is small, and since hinged girder and main canopy are to be nested together, longitudinal cross dimensions does not become substantially
Change, is particularly suitable for the thin seam working surface for having strict demand to bulk.
(3) top beam front end support top power is big, and bearing capacity is strong, hinged girder and main canopy by case nested structure be linked to be one it is whole
Body, top beam globality is strong, and top beam front support ability is big, and bearing capacity is strong.
