Abstract
The utility model discloses a kind of hydraulic support top beam side guard plate thrust gear, including back timber body, the left side backplate and right side backplate of the back timber body left and right side are arranged on, and the side being arranged in back timber body pushes away jack；The side pushes away jack to be symmetrical with back timber body center line along back timber body laterally left and right horizontally disposed two, left side pushes away jack and right side pushes away the piston rod end of jack and is respectively positioned on back timber body midline position and is connected respectively by lock pin with back timber body, left side pushes away jack and right side push away jack cylinder ends bar is derived with corresponding left side by bearing pin respectively, right side derives one end of bar and is hinged, left side derives bar and right side derives the other end of bar and is connected respectively by sleeve with the corresponding left side backplate, right side backplate.The utility model advantage is the quick commutation for realizing the hydraulic support top beam body left and right side backplate, saves manpower and materials, securely and reliably, simple in construction, convenient disassembly.
Description
Technical field
Hydraulic support top beam is the utility model is related to, more particularly, to hydraulic support top beam side guard plate thrust gear.
Background technology
Coal resources in China reserves very abundant, it is growing with comprehensive mechanized coal mining technology, it is main as fully mechanized mining technology
The hydraulic support technology of part also needs constantly to reform.In order to meet the needs of colliery is highly efficient and productive, high working face, big work
Support resistance hydraulic turns into a kind of trend.With the raising of hydraulic support stand height, in order to meet stability requirement, support is wide
Degree and centre-to-centre spacing necessarily increase, and traditional hydraulic support top beam side guard plate thrust gear can only realize unilateral backplate stretching and
Retract, support width and the increased demand of centre-to-centre spacing can not have been met.
The content of the invention
The utility model purpose is to provide a kind of hydraulic support top beam side guard plate thrust gear.
To achieve the above object, the utility model takes following technical proposals：
Hydraulic support top beam side guard plate thrust gear described in the utility model, including back timber body, are arranged on the back timber
The left side backplate and right side backplate of body left and right side, and the side being arranged in back timber body push away jack；The side pushes away jack
Back timber body center line is symmetrical with along back timber body laterally left and right horizontally disposed two, left side pushes away jack and right side pushes away jack
Piston rod end is respectively positioned on back timber body midline position and is connected respectively by lock pin with back timber body, and left side pushes away jack and right side pushes away
The cylinder ends of jack derive bar by bearing pin with corresponding left side respectively, one end of right side derivation bar is hinged, and left side pushes away
The other end that guide rod and right side derive bar is connected by sleeve with the corresponding left side backplate, right side backplate respectively.
The utility model advantage is the quick commutation for realizing the hydraulic support top beam body left and right side backplate, saves
Manpower and materials, securely and reliably, simple in construction, convenient disassembly.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiments of the invention are elaborated below in conjunction with the accompanying drawings, the present embodiment using technical solution of the present invention before
Put and implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to down
State embodiment.
As shown in figure 1, hydraulic support top beam side guard plate thrust gear described in the utility model, including back timber body 1, set
Jack is pushed away in the left side backplate 2 and right side backplate 3 of the left and right side of back timber body 1, and the side being arranged in back timber body 1；Institute
State side and push away jack to be symmetrical with the center line 4 of back timber body 1 along back timber body 1 laterally left and right horizontally disposed two, left side pushes away jack
5 and right 6 sides push away the piston rod end of jack and be respectively positioned on the position of 1 center line of back timber body 4 and respectively by lock pin 7,8 and back timber body 1
Connection, left side pushes away jack 5 and right side pushes away the cylinder ends of jack 6 respectively by bearing pin and corresponding left side derivation bar 9, the right side
One end that side derives bar 10 is hinged, left side derive bar 9 and right side derive the other end of bar 10 respectively by sleeve with it is corresponding
The left side backplate 2, right side backplate 3 are connected.
During utility model works, according to the actual conditions of fully mechanized coal face, jack 5 is pushed away by left side and right 6 sides push away it is very heavy
Top, can single movement or flexible movements simultaneously use, meanwhile, shortened the arm length that side derives bar compared to traditional side push mechanism
Degree.
In the description of the invention, it is necessary to explanation, the orientation of instruction such as term "left", "right", " interior ", " outer " or
Position relationship is to be based on orientation shown in the drawings or position relationship, is for only for ease of the description present invention and simplifies description, without
It is instruction or implies that signified device or element there must be specific orientation, with specific azimuth configuration and operation, therefore not
It is understood that as limitation of the present invention.
