Abstract
The invention relates to the field of supporting and protecting in a coal mine roadway and discloses a rolling moving method of a hydraulic bracket. The method is completed by a rolling system in fit with the hydraulic bracket; the rolling system is fixed on a top beam of the hydraulic bracket, sliding friction between the top beam and a top plate is changed to be rolling friction, and the direct moving of the bracket is achieved by rolling effect. According to the method, column lifting and falling steps of the hydraulic bracket are omitted in a bracket moving process, the bracket moving process is simplified, meanwhile adverse effect caused by the longitudinal instability factor of the top plate can be effectively reduced, the supporting and protecting intensity of the hydraulic bracket is improved, the advance speed of a working face is accelerated, and achievement of high yield and high efficiency is facilitated.
Description
Technical field
The present invention relates to colliery tunnel support field, for improvement of the moving manner of hydraulic support.
Background technology
Along with the increase of the pit mining degree of depth, Mechanion, automaticity continue to increase, and fully-mechanized mining technical level improves constantly.In working face mining process, hydraulic support moves frame at every turn and all needs frequently to fall post, setting prop, and operation is loaded down with trivial details, and hand labor amount increases, and potential safety hazard increases.In order to give full play to the supporting performance of support, reduce and move frame operation, increase the contact area of back timber and top board, improve and move frame efficiency, need improve the moving manner of hydraulic support.
Summary of the invention
The rolling that the invention provides a kind of hydraulic support moves frame method, and the method utilization is fixed on the rolling system on hydraulic support top beam, and the sliding friction between hydraulic support top beam and top board is become to rolling friction, realizes pushing and sliding move frame by rolling action.
Compared with prior art, the invention has the beneficial effects as follows: the method has been saved and fallen post and setting prop step in hydraulic moving stand process, has simplified and has moved frame operation, is convenient to realize and directly moves frame.Meanwhile, the inventive application of rolling system on hydraulic support can effectively reduce the adverse effect that in support passing process, the longitudinal destabilizing factor of top board is brought, and increases supporting area, improves the supporting intensity of support, reduces and moves frame operation, guarantees production safety.

In figure, carrier wheel (1), crawler belt (2), upper bogie wheel (3), lower bogie wheel (4), bogie wheel upper mounted plate (5), bogie wheel bottom plate (6), upper whorl axial (7), lower wheel shaft (8), spring (9), groove (10), bolt hole (11) and hydraulic support (12).
Detailed description of the invention
Core of the present invention is that a kind of rolling of hydraulic support moves frame method, and below in conjunction with accompanying drawing and detailed description of the invention, the invention will be further described.
The rolling of hydraulic support moves a frame method, is mainly to utilize the rolling system being fixed on hydraulic support top beam, directly moves frame by the way of contact realization changing between back timber and top board.Wherein rolling system is bright spot of the present invention, and it is the guarantee that the method is implemented smoothly.The method is fixed on set cap by the bolt hole (11) on fixed head (6) by rolling system, forms new supporting entirety, performance support action.
The method is positioned over the upper whorl axial of rolling system (7) and lower wheel shaft (8) in groove (10), and groove has certain crooked radian, can with wheel shaft close contact, be fixed firmly.
The method is by crawler belt (2) the contact top board of rolling system, in support passing process, bogie wheel in utilization (3) passes to hydraulic support (12) back timber with the rolling of lower bogie wheel (4) by surrouding rock stress, drives support to move forward.
The crawler belt (2) of the method utilization rolling system can longitudinally move freely in hydraulic support (12), after work plane coal cutting completes, without what carry out support, post and setting prop step fall, directly carry out pushing and sliding and move frame, accelerate the fltting speed of work plane, be convenient to realize high-yield and high-efficiency.
Claims (4)
