Description
Technical field
A kind of comprehensive mining hydraulic bracket reach connector of the present invention, is related to what is used on a kind of fully-mechanized mining working, to hydraulic pressure branch
The connecting component apparatus used when frame is moved forward, belongs to field of mining equipment.It is more particularly to a kind of that liquid is made by the buffering of spring
Press the fltting speed of support and stop the connecting component apparatus that speed is gradually changed.
Background technology
At present, when fully-mechanized mining working works, with mining work progress, it is necessary to by oil cylinder by hydraulic support forward
Promote, in order to ensure whole working face safety, it is necessary to hydraulic support steadily advances, conventional is directly by oil cylinder and hydraulic pressure
Support is attached, and in translation, oil cylinder pushes directly on hydraulic support translation, and starting speed is directly raised to maximum from 0, during stopping
Speed moment drops to 0, not perfectly flat steady when hydraulic support is started to walk and is stopped, and requires higher, the lotus that oil cylinder is born to oil cylinder
Carry larger, existing to be connected between oil cylinder and hydraulic support by universal joint, this kind of universal joint is in space
Excessively flexibly, the axial direction transmission of connector can not be realized under normal circumstances, when oil cylinder pushing universal joint reaches dead angle position
When, it could continue to transfer power to hydraulic support, and the thrust of oil cylinder is offset in the presence of universal joint, meeting
Cause the translation direction of hydraulic support to offset, influence the support protection of getting working face.
The content of the invention
In order to improve the above situation, a kind of comprehensive mining hydraulic bracket reach connector of the present invention provides a kind of by spring
Buffering makes the fltting speed of hydraulic support and stops the connecting component apparatus that speed is gradually changed.Cost is cheap, easy to spread.
A kind of comprehensive mining hydraulic bracket reach connector of the present invention is realized in：Before a kind of comprehensive mining hydraulic bracket of the present invention
Connector is moved by main body cylinder, drive link, stop collar, main connecting stud, main six face fixed stations, universal adapter sleeve, tensioning spring, cunning
Dynamic pin, sliding groove, auxiliary six face fixed station, auxiliary connecting stud and revolution adapter sleeve form, and are provided with sliding groove in the main body cylinder, institute
State and be equipped with screw thread on the outside of main body cylinder, drive link one end is placed in main body cylinder, and the other end passes from main body cylinder one end, the drive link
Screw thread is equipped with the other end, sliding pin one end is placed on drive link, and the other end is placed in sliding groove, and stop collar is placed on drive link
On, tensioning spring is placed on drive link, and between main body cylinder one end and stop collar, it is another that universal connection is placed on drive link
On one end, screw thread is equipped with the universal adapter sleeve inwall, and is meshed with the screw thread on the drive link other end, main six faces are fixed
Platform is placed on universal adapter sleeve, and main connecting stud one end is placed on main six face fixed stations, and revolution connection is placed in main body cylinder, institute
State and be equipped with screw thread on revolution adapter sleeve inwall, and be meshed with the screw thread on the outside of main body cylinder, auxiliary six face fixed station is placed in revolution and connected
In female connector, auxiliary connecting stud one end is placed on the fixed station of auxiliary six face.
The invention further relates to a kind of application method of comprehensive mining hydraulic bracket reach connector, it is characterised in that in use, working as
When being moved forward to hydraulic support, auxiliary connecting stud is connected with hydraulic support first, main connecting stud is connected with oil cylinder
Connect, cylinder efficient, promote main connecting stud, main connecting stud promotes main six face fixed stations, and main six face fixed stations pass through universal company
Female connector promotes drive link, and drive link moves along main body cylinder, and drives sliding pin to be moved along sliding groove, tensioning spring pressure
Contracting, row buffering is entered to the propulsive force of oil cylinder, and then tensioning spring promotes the gradual speedup movement of main body cylinder, main body cylinder passes through the company of revolution
Female connector promotes the gradual speedup movement of auxiliary six face fixed station, and auxiliary six face fixed station promotes the gradual speedup movement of auxiliary connecting stud, and then
Auxiliary connecting stud promotes the gradual speedup of hydraulic support to move forward, and when sliding pin is moved to sliding groove one end, drive link is direct
Main body cylinder movement is promoted, now, the motive force of drive link is consistent with the motive force of oil cylinder, and the translational speed of hydraulic support carries
Maximum is risen to, then hydraulic support moves in the motive force held stationary of oil cylinder；
When hydraulic support stops, main connecting stud is not stressed, and drive link is not promoted, due to the elastic force of tensioning spring itself,
And then tensioning spring is gradually upheld, and the gradual reduction of speed movement of main body cylinder is driven, and then main body cylinder is driven by auxiliary connecting stud
The gradual reduction of speed movement of hydraulic support, now, drive link moves backward along main body cylinder, and drives sliding pin anti-along sliding groove
To movement, when sliding pin is moved to the sliding groove other end, hydraulic support speed is reduced to zero, no longer moves；
The present invention when not in use, using die nut is pulled down main connecting stud by main six face fixed stations from oil cylinder, is used
Die nut is pulled down auxiliary connecting stud by auxiliary six face fixed station from hydraulic support, and reach is made by the buffering of spring
The purpose that the fltting speed and stopping speed of hydraulic support are gradually changed.
Beneficial effect.
First, it is simple in construction, it is convenient and practical.
2nd, cost is cheap, easy to spread.
3rd, smoothness during hydraulic support movement can be improved.
4th, make the fltting speed of hydraulic support by the buffering of spring and stop speed being gradually changed.
