In recent years, along with the fast development of China's economic construction, heavy construction class project under construction have also been obtained unprecedented development, various engineering project numerous and complicated.As indispensable instrument a kind of in practical engineering application---hydraulic jack, in real production application, numerous engineering fields such as machinery, metallurgy, mining are also related to.In order to the needs of production application, the hydraulic support frames type of hydraulic jack is constantly strengthened, the cylinder diameter of the jack used with support equipped is also constantly strengthened, and this is on the basis of satisfied real production application, undoubtedly in the difficulty virtually adding hydraulic jack dismounting.In actual unloading process, after the fairlead of hydraulic jack is disassembled, pressurization emulsion is just released the post alives of jack from cylinder barrel, and the jack work post be pushed out will be lifted by driving.Thus, in jack unloading process, one that the lifting problem of jack post alive just becomes in production application must not irrespective problem.
The work of existing lifting jack post alive is generally completed by shop traveller, in the process that jack post alive is pushed out, driving first hangs post alive by the one end preferentially released by hanging belt, after certain distance released by post of living, the other end of post alive is hung again with another root hanging belt, post of living could be released cylinder barrel completely, in this process practical operation, operating personnel must note the post alive played by hanging belt in careful operation moment, avoid it from landing hanging belt, such operating process not only causes very large pressure to affected personnel, and the too much time need be expended, operating efficiency is extremely low, simultaneously when post lived by the jack that lifting is short and thick, operation can be abnormal difficult, be easy to the landing causing post alive in operation, to damage post plated surface layers of chrome alive, and there is certain potential safety hazard, this causes unnecessary trouble and loss by the production of reality.
Utility model content
In order to solve the problem, the purpose of this utility model proposes the manual bracket system of a kind of jack, by arranging flexible adjustable bracket, can in jack unloading process, adjustable bracket is utilized preferentially to be shelved on bracket by post alive for jack, then the lifting relying on driving to carry out jack post alive, so just can save manpower, eliminate safe hidden trouble, improve removal efficiency.
The utility model in order to the taked technical scheme that solves the problem is: the manual bracket system of a kind of jack, comprise support baseboard, detent mechanism, retaining mechanism, swivel nut, lifting screw, governor motion and bracket, described detent mechanism is connected on support baseboard by securing member, described detent mechanism is provided with the through hole for installing swivel nut, swivel nut to be linked into an integrated entity structure by securing member and detent mechanism, the lower end of lifting screw screws in swivel nut, the upper end of lifting screw to be linked into an integrated entity structure by securing member and bracket, lifting screw between swivel nut and bracket is also provided with governor motion, by the change in displacement of governor motion adjustment lifting screw in swivel nut, be provided with the side of swivel nut the locating hole be connected at detent mechanism, described retaining mechanism is arranged in locating hole, the side of lifting screw is held out against to limit lifting screw moving freely in swivel nut by retaining mechanism.
The center of described support baseboard is provided with through hole, and detent mechanism is arranged in through hole and is linked into an integrated entity structure by screw and support baseboard.
Described governor motion comprises a driving ring and is arranged on the handle of driving ring outside, is provided with the internal thread matched with external screw thread on lifting screw, realizes the change in displacement of lifting screw in swivel nut by rotating drive ring in the through hole of driving ring.
Described bracket, in " V " type structure, the upper angled face of its weight-bearing surface is provided with cushion pad.
Described retaining mechanism is one with externally threaded cylindrical component, by adjustment cylindrical component in the degree of depth of locating hole to hold out against on the side surface of lifting screw.
The beneficial effects of the utility model:
The manual bracket system of a kind of jack described in the utility model, the orientable lifting screw of one liftable is set in swivel nut, when jack post alive is pushed out from cylinder barrel, regulate by governor motion and the height of the height of positioned-lifting screw rod and then control bracket system, making to live when post is completely pushed out of to drop on bracket easily, keep the two ends of jack post alive to be in vacant state simultaneously, just the two ends of jack post alive easily can be hung when being lifted by hanging belt by driving again, so save the working time greatly, eliminate safe hidden trouble, improve lifting efficiency, the cushion pad that bracket system load-bearing side surface is arranged simultaneously can play buffer protection function, effectively prevent the chromium coating on jack post surface alive from damaging.
