Description
Technical field
This utility model relates to a kind of hydraulic support.
Background technology
In coal-cutting machinery apparatus field, it is to apply in lane that those skilled in the art both knows about end hydraulic support
Carrying out supported laneway top board in road, the end hydraulic support used by present stage includes a base and two tops
Beam, is equipped with at least two hydraulic jacks between each back timber and base, between each back timber and base the most all
It is provided with linkage.Using the hydraulic support of said structure, overall dimensions is big, Heavy Weight, and structure is multiple
Miscellaneous, operation complexity, manufacturing cost is high.
Meanwhile, along with the continuous exploitation of coal, the reserves of coal are fewer and feweri, so the coal seam of difficult exploitation (such as:
The exploitation of half-edge coal seam) cause the continuous attention carrying out people, owing to half-edge coal seam has certain inclination
Angle, in order to prevent coal-winning machine from gliding, the pulling winch outside needing by tunnel draws, again owing to mining
Shape is at a certain angle, thus at traction steel wire hydraulic support in tunnel during machine work and between tunnel
Time will certainly contact with hydraulic support, therefore need on hydraulic support, to design a mechanism traction steel wire is led
To and transition.
Utility model content
The purpose of this utility model is to provide a kind of hydraulic support, on the premise of meeting supporting, outside reaching
Shape size is little, lightweight and the purpose of low cost of manufacture.
For solving above-mentioned technical problem, the technical solution of the utility model is: a kind of hydraulic support, the end of including
Seat and two back timbers, back timber described in two and be provided with portal frame between described base, it is positioned at described portal frame both sides
Described back timber and described base between be hinged with power set；
Described portal frame includes the support body being fixedly installed on described base, with back timber correspondence position every described
Described support body in the most vertically slidable lead that is provided with, described lead is arranged on described back timber.
Improving as one, described support body is provided with pulley mechanism.
As further improving, described pulley mechanism includes pulley and the hinged seat being arranged on described support body,
Described pulley rotation is installed in mounting seat, is provided with candan universal joint between described hinged seat and described mounting seat.
As further improving, described hinged seat rotates and is installed on described support body.
As further improving, original state, the upper table of back timber described in the upper surface of described support body and two
In face is generally aligned in the same plane, it is provided with rake with the described support body of described back timber correspondence position, inclines with described
Tiltedly the described back timber of portion's correspondence position is provided with groove.
Owing to have employed technical scheme described above, having of a kind of hydraulic support provided by the utility model
Benefit effect is as follows:
Owing to being provided with portal frame between two back timbers and base, this portal frame includes the frame being fixedly installed on base
The most vertically slidable in body, with the support body of every back timber correspondence position the lead being arranged on back timber is installed,
Thus in the application, drive back timber to raise by the driving of power set and carry out supporting, in this process, lead
Xiang Zhuhui under the drive of back timber along support body upward sliding, compared with traditional hydraulic support, simple in construction,
Easy to operate, overall dimensions is little, lightweight, low cost of manufacture；Meanwhile, joining by support body and lead
Close and two back timbers are contacted together, can mutually transmit during stress, substantially increase and bear side force
With the ability of twisting resistance, and the integrated support intensity of this hydraulic support have also been obtained and is greatly improved.
Owing to portal frame is provided with pulley mechanism, thus by pulley structure realize pulling winch and coal-winning machine it
Between transition, not only traction steel wire supported and guided, and can be prevented effectively from traction steel wire with should
Hydraulic support interferes and contacts, and the exploitation for half-edge coal seam is laid a good foundation.
Owing to being provided with candan universal joint between hinged seat and mounting seat, thus achieve cunning by candan universal joint
The swing of four direction around wheel, the need that during to adapt to specific works, traction steel wire direction changes
Ask.
It is installed on support body owing to hinged seat rotates, thus when needing pulley to deflect certain angle at work,
Just can be realized by hinged seat rotation on support body, meet demand during work further.
In being generally aligned in the same plane due to original state, the upper surface of support body and the upper surface of two back timbers, thus logical
Cross this structure and ensure that the height of support body, and then ensure that pulley has certain height, to ensure traction steel
Silk and pulley have good matching relationship, for ensureing that normal traction work provides guarantee.
Owing to being provided with rake with the support body of back timber correspondence position, set on the back timber of rake correspondence position
Fluted, thus coordinating by rake and groove, on the premise of guarantee support body height, support body and top
Will not interfere between beam.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And embodiment, this utility model is further elaborated.Should be appreciated that described herein specifically
Embodiment, only in order to explain this utility model, is not used to limit this utility model.
As Fig. 1 to Fig. 3 jointly shown in, a kind of hydraulic support, including base 2 and two back timbers 1, two back timbers
It is provided with portal frame 3 between 1 and base 2, is hinged with between the back timber 1 and base 2 of portal frame 3 both sides
Power set 5；This portal frame 3 includes the support body 31 being arranged on base 2, position corresponding with every back timber 1
