Abstract
The utility model provides a combined hydraulic rack with a guiding mechanism. One end of a supporting hydraulic cylinder is hinged to a base, and the other end is hinged to a top beam. The base is provided with a guide sleeve vertical to the base. A ball socket supporting base is disposed on a face of the top beam, with respect to the base. The center of the ball socket is disposed on a central axis of the guide sleeve. A ball head is disposed in the ball socket, forming a spherical hinge pair. The ball head can freely rotate in the ball socket and is fixedly connected to a guide bar. The guide bar is inserted in the guide sleeve and can move along the direction of the axis. The ball socket supporting base, the ball head, the guide bar and the guide sleeve form a guiding mechanism which can restrain the top beam and the base to conduct a parallel and relative displacement. The top beam can conduct a universal swing with the spherical hinge pair as the center. When the rack is applied with setting load, pressure change can be adapted between the top beam and a top plate, and between the base and a base plate, and thereby contact area can be effectively increased and damage of mechanical deformation due to stress concentration on the top beam and the base can be reduced.
Description
One, technical field
The utility model relates to the assembled hydraulic support of a kind of tape guide mechanism, and it belongs to the mining support technical field.
Two, background technology
Along with China's mining industry developing rapidly of cause of especially mining, the support apparatus that is used for the underground mining work plane also is promoted thereupon, hydraulic support is that use is maximum in the support apparatus, at present most of what use is a kind of sliding assembled hydraulic support with joist at the small production work plane, because the existence of joist is so that hydraulic support in use is subject to all limitations, because sliding assembled hydraulic support does not have base, hydraulic prop independent support less stable, being not orthogonal to hydraulic prop at pressure is the accident that frame easily occurs.
Three, summary of the invention
For solving the defective that has now with the sliding assembled hydraulic support existence of joist, the utility model provides the assembled hydraulic support of a kind of tape guide mechanism, by base, back timber, hydraulic prop and guiding mechanism four most of formations, can use separately also and can many to be used in combination, owing to there is not joist, can greatly improve the lifting travel of back timber, thereby moving resistance and rate of depreciation have been reduced, can effectively increase the service life, thereby reduce cost of winning, owing to being provided with base and guiding mechanism so that stability is improved, thereby reduced the generation of the accident of falling the frame, simultaneously safety is further enhanced.
The technical solution adopted in the utility model is: the assembled hydraulic support of a kind of tape guide mechanism, comprise base (1), front support hydraulic cylinder (2), back timber (3), ball-and-socket supporting seat (4), bolt (5), ball pivot back-up ring (6), bulb (7), guide peg (8), fairlead (9), rear support hydraulic cylinder (10), it is characterized in that: base is set, one end and the base of front support hydraulic cylinder and rear support hydraulic cylinder are hinged, the other end and the back timber of front support hydraulic cylinder and rear support hydraulic cylinder are hinged, base is provided with a fairlead perpendicular to base, back timber is provided with a ball-and-socket supporting seat at the face of relative base, the center of ball-and-socket is on the central axis of the fairlead of base, bulb is installed in the ball-and-socket, the ball pivot back-up ring links and makes bulb can not break away from ball-and-socket with bolt and ball-and-socket supporting seat and forms a typed ball bearing pair, bulb can freely rotate in ball-and-socket, bulb and guide peg are connected, the bulb center is on the center line of guide peg, can move along axis direction in the fairlead of guide peg inserted base, by the ball-and-socket supporting seat, bulb, guide peg and fairlead consist of guiding mechanism, guiding mechanism can retrain two degree of freedom that produce parallel relative displacement between back timber and the base, do not retrain other degree of freedom, the purpose that adopts ball pivot to connect is to make back timber can make universal swing centered by typed ball bearing pair, the variation of its pressure of self adaptation between back timber and the top board and between base and the base plate when support applies setting load effectively increases contact area and reduces stress and concentrate the destruction that back timber and base are caused mechanically deform.
The beneficial effects of the utility model are: owing to being provided with base and guiding mechanism so that stability is improved, thereby a back timber that has reduced the accident of falling the frame can be made universal swing centered by typed ball bearing pair, the variation of its pressure of self adaptation between back timber and the top board and between base and the base plate when support applies setting load effectively increases contact area and reduces stress and concentrate the destruction that back timber and base are caused mechanically deform.Give birth to, simultaneously safety is further enhanced.Adopt ball pivot to be connected between guiding mechanism and the back timber,
