Specific embodiment
As shown in Figs 1-4, a kind of specific embodiment of postposition guide rod hydraulic support, including pedestal 1, pedestal 1 include two
Base body 103 arranged side by side, the front end of two base bodies 103 are connected with gap bridge 104, guide sleeve 101 across two
It above a base body, and is welded to connect with two base bodies, two base bodies is connected as an entirety, solve to move frame
The problems such as with adjusting frame difficult.It is all provided on each base body 103 there are two needling 102, before being located at two base bodies 103
Two 102 flushes of needling of side, positioned at two 102 flushes of needling of two 103 rear sides of base body.Each needling
Internal Spherical Surface is hinged with the lower end of column, and the upper end of column is hinged with top beam, and column is made to have certain swing angle, four columns
It is mainly used to supporting top beam and undertakes downward load.Flexible guide rod 3 is installed in guide sleeve, forms guide-bar mechanism, it is flexible to lead
It is connected on the downside of the top of bar and the rear end of top beam, provides guiding for the top beam of hydraulic support.Guide sleeve is deep into base body
On lower plate, it can guarantee the magnification of guide-bar mechanism to greatest extent.Four columns 2 include two front columns 201 and two
Rear column 202.Two front columns 201 are separately mounted in two needlings 102 of front side, and two front columns 201
Top turn forward, two rear columns 202 are separately mounted in two needlings 102 of rear side, and two rear columns
202 top retreats, and can resist a part of horizontal force from top beam, while can avoid rear column when hydraulic support work
With the interference of flexible guide rod.
4 tail portion of top beam is hinged with waste rock board 6 by pin shaft 5, and waste rock board lower end is in scoop structure, upper end pin shaft 5
It is articulated with the tail portion of top beam, for preventing goaf spoil from pouring in, and protects flexible guide rod.Torsional spring is provided on the pin shaft 5
8, torsional spring is placed between top beam and waste rock board, and the torsional spring 8 is after the lower end of the waste rock board 6 presses to the guide sleeve 101
Side provides elastic force, guarantees that waste rock board lower end is fitted closely with guide sleeve trailing flank, can avoid occurring due to the accumulation of lower part spoil
Drop frame is influenced, while second supporting point can also be provided for waste rock board.
The first mounting hole 105, side of the guide sleeve 101 close to 104 sides of passing a bridge are offered on the gap bridge 104
The second mounting hole 106 is offered on wall, and column righting dress is mounted on first mounting hole 105 and the second mounting hole 106
7 are set, the column erection device 7 includes the retainer 701 being connected on first mounting hole 105 or the second mounting hole 106
Be fixed on two elastic internal support devices 702 that 701 upper end of retainer extends to two sides, two elastic internal support devices
702 are respectively supported on two front columns 201 or two rear columns 202.Elastic internal support device is fixed on retainer, is stood
The retainer of column erection device is mounted on the first mounting hole, and elastic internal support device both ends annular surface is attached at front column cylinder body circle
Cylinder prevents when hydraulic support zero load due to gap between guide rod and guide sleeve of stretching is big to front column with elastic centralizing support
The excessive problem of the top beam double swerve of appearance.In addition increase by one group of column erection device, column to improve column righting effect
The retainer of erection device is mounted on the second mounting hole, and elastic internal support device both ends annular surface is attached at rear column cylinder body cylinder
Face is used to carry out righting to rear column, it is ensured that hydraulic support self stability to rear column with elastic centralizing support.
Embodiment described above is only that preferred embodiment of the invention is described, and is not carried out to the scope of the present invention
It limits, without departing from the spirit of the design of the present invention, those of ordinary skill in the art make technical solution of the present invention
Various changes and improvements, should all fall into claims of the present invention determine protection scope in.
