Abstract
The utility model discloses a strut efficiency nondestructive formula articulated back timber mechanism, including whole back timber and articulated front beam, be equipped with two hinge between the front end of whole back timber and the rear end of articulated front beam. And a jack is not arranged between the whole top beam and the hinged front beam. In the transportation process, one hinge shaft is detached, the whole top beam is hinged with the hinged front beam through the other hinge shaft, and the front end of the hinged front beam naturally droops; in the supporting process, two hinge shafts are arranged, and the whole top beam and the hinged front beam are fixedly connected into a whole through the two hinge shafts. The supporting efficiency of the top beam and the top plate can be improved, and the problem of underground transportation can be solved. The support of any jack is not needed, so that the cost is reduced, and the maintenance strength is reduced.
Description
Technical Field
The utility model relates to a colliery is combined and is adopted hydraulic support, especially relates to a strut the articulated back timber mechanism of efficiency nondestructive formula.
Background
The structure-top beam of hydraulic support direct contact roof has always been the major structure of support design, and the structural style that present support top beam generally used has whole back beam, whole top beam articulated front beam, back beam area flexible roof beam 3.
In the prior art, aiming at a mine with too long structural parts and difficult well descending, the length of the top beam can be shortened by adopting a structure that the whole top beam is hinged with the front beam, but when the working resistance of the support reaches a certain limit, a jack hinged with the front beam is forced to automatically return liquid, the front beam is low in head and cannot be connected with a top plate, and the supporting efficiency is reduced. The problem of underground transportation is difficult to solve, and the advantages of the whole top beam and the whole top plate are achieved.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a strut efficiency harmless formula articulated back timber mechanism.
The utility model aims at realizing through the following technical scheme:
the utility model discloses a strut efficiency nondestructive formula articulated back timber mechanism, including whole back timber and articulated front-axle beam, be equipped with two hinge between the front end of whole back timber and the rear end of articulated front-axle beam.
By the foregoing the utility model provides a technical scheme can see out, the embodiment of the utility model provides a strut the articulated back timber mechanism of efficiency nondestructive formula, can increase the efficiency of strutting of back timber roof, can also solve the transportation problem that goes into the well. The support of any jack is not needed, so that the cost is reduced, and the maintenance strength is reduced.

Fig. 2 is a schematic structural view of an articulated cap mechanism with lossless supporting efficiency provided by the embodiment of the utility model.
In the figure:
1. the integral top beam comprises a front hinged beam 2, a front hinged beam 3, a first hinged shaft 4 and a second hinged shaft.
Detailed Description
Embodiments of the present invention will be described in further detail below. Details not described in the embodiments of the present invention belong to the prior art known to those skilled in the art.
The utility model discloses a strut efficiency harmless formula articulated top beam mechanism, the concrete implementation mode of its preferred is:
the double-head beam comprises a whole top beam and a hinged front beam, wherein two hinge shafts are arranged between the front end of the whole top beam and the rear end of the hinged front beam.
And a jack is not arranged between the whole top beam and the hinged front beam.
The two hinge shafts are horizontally arranged in front and back.
In the transportation process, a hinge shaft is detached, the whole top beam is hinged with the hinged front beam through another hinge shaft, and the front end of the hinged front beam naturally droops;
and in the supporting process, two hinge shafts are arranged, the whole top beam and the hinged front beam are fixed through the two hinge shafts, and the hinged front beam and the whole top beam are connected into a whole supporting device.
The utility model discloses a strut efficiency nondestructive formula articulated back timber mechanism has researched and developed the structural style of one kind "unlimited approaching" whole back timber, and this kind of structural style mainly is too long to the structure, and the mine research and development of well descending difficulty. The problem of underground transportation is solved, and all advantages of the whole top beam and the whole top plate are achieved.
The specific embodiment is as follows:
as shown in fig. 1 and 2, the structural design of the double-stage hinge shaft is adopted. The strength of the double-hinged shaft and the main structure of the top beam are designed according to the stress condition of the top beam (top beam bending moment diagram).
The utility model discloses can increase the efficiency of strutting of back timber roof, can also solve the transportation problem of going into the well. The support of any jack is not needed, so that the cost is reduced, and the maintenance strength is reduced. The utility model discloses the achievement is worth wideling popularize.
The above description is only for the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are all covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
