Abstract
The utility model relates to a hydraulic nut loosening tool, which is composed of a press head, a core clamper, a tong head, a hydraulic pump, an oil return screw nut, a fixed handle, a moving handle, a fixed grip, and a moving grip. Compared with the prior art, because the utility model uses the hydraulic nut loosening tool, a plurality of types of nuts can be disassembled. The utility model has the advantages of convenient use and simple operation.
Description
Technical field:
The utility model relates to a kind of manual teardown instrument, and particularly a kind of hydraulic pressure nut that is used to dismantle nut breaks device.
Background technology:
In existing technology, phenomenons such as nut takes place that corrosion is killed easily, make that the dismounting of nut is very difficult, usually the method that adopts is with common special-purpose nut extracting tool now, the extracting tool of the corresponding a kind of special use of one type nut, use very inconveniently, when the nut corrosion is killed, do not dismantle by manpower fully at all.
Summary of the invention:
Technical problem to be solved in the utility model is: 1, and when the nut corrosion was killed, existing extracting tool by manpower, was difficult to finish field-strip fully; 2, the nut type is too many, and the corresponding a kind of removal tool special of a kind of nut, uses very inconvenient.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to provide a kind of hydraulic pressure nut and break device, described hydraulic pressure nut breaks device by pressure head, top, binding clip, hydraulic pump, the oil return nut, fixed handle, flexible handle, fixedly handle and movable handle constitute, described pressure head is provided with centre bore, the shape of described centre bore can be regular hexagon, one end of described pressure head is provided with an otch, one end of the both sides of the otch of described pressure head and described binding clip interconnects, concrete connected mode can connect for screw, the longitudinal center line of described binding clip is provided with manhole, described binding clip is connected with hydraulic pump, concrete connected mode can be for being welded to connect, described hydraulic pump is by the pump housing, piston, piston rod, return line, valve piston, shoe cream room and pumping cavity constitute, described piston is arranged in the described pump housing, described piston rod one end is connected with described piston, the other end passes the front end of the pump housing and the manhole of binding clip, stretch in the described pressure head, and with described top interconnecting, described pumping cavity is by described piston, the piston rod and the pump housing constitute, described shoe cream room is made of the piston and the pump housing, between described shoe cream room and described pumping cavity, be provided with return line, described return line is provided with the oil return nut, described valve piston is arranged in the shoe cream room, the rear end of described fixed handle and described hydraulic pump interconnects, concrete connected mode can be for being welded to connect, described flexible handle is arranged on the described pump housing, be articulated and connected for pivot pin between the front end of described flexible handle and the described pump housing, described valve piston and described flexible handle interconnect, and are respectively arranged with fixedly handle and movable handle at the end of described fixed handle and flexible handle.
The utility model and prior art contrast, because used the hydraulic pressure nut to break device, can dismantle polytype nut, and be easy to use, simple to operate.
