Description

Ratchet wrench applied to valve hand wheel

Technical Field

The utility model relates to the technical field of ratchet wrenches, in particular to a ratchet wrench applied to a valve hand wheel.

Background

At present, common tools for opening and closing valves comprise a pipe wrench, an F-shaped wrench and the like, wherein the pipe wrench comprises a movable jaw, an adjusting wheel, a handle, a spring piece and the like, the size of the jaw can be adjusted by rotating the adjusting wheel, when the valve is opened and closed, jaw teeth of the jaw are firstly meshed with a valve hand wheel, and then the handle is rotated to realize opening and closing. The F-shaped wrench is a tool welded by steel materials and the like, and is shaped like an F. When a valve is switched on and off by using a common pipe wrench, the hand wheel is easily damaged by iron objects, and the pipe wrench needs to be taken out to find a proper angle again to be driven on the valve hand wheel again after rotating a certain angle every time, so that time and labor are wasted, the efficiency is low, and the construction progress is influenced. When (two) utilize F type spanner switch valve, except the drawback that ordinary breakout tongs exists, still have the risk on safety, because F type spanner is formed by the welding, the opening size can not be adjusted, appears in the phenomenon of skidding easily during the switch valve, causes the person to receive the injury.

For the reasons mentioned above, some tools for rotating a valve hand wheel have been invented, such as the patent publications CN202592271U, CN 202895150U and CN 207309807U, wherein CN202592271U discloses a technical solution that includes a ratchet wrench and a valve locking device disposed on the valve hand wheel, and the valve locking device is locked with the ratchet wrench. The left clamping piece or the right clamping piece arranged at the two ends of the connecting piece is firmly clamped with the valve hand wheel, and then the nut on the connecting piece is clamped with the ratchet wrench, so that the valve can be conveniently opened and closed. The research shows that the scheme has certain defects, for example, the clamping piece for clamping the valve hand wheel is welded on the nut of the ratchet wrench, so that the size of the clamping piece is fixed, and the clamping piece cannot be used universally for valve hand wheels with different sizes.

The technical scheme disclosed by CN 202895150U comprises a clamping base and a force application bar, wherein the upper part of the clamping base is a ratchet wheel chassis, and five claws are uniformly welded on the periphery of the ratchet wheel chassis; one end of the forcing lever is provided with a ratchet wheel shifter, and a shifting claw of the ratchet wheel shifter is matched with the ratchet wheel chassis, so that the defects of repeated clamping and repeated pulling of an F-shaped spanner are overcome. Similar to the first prior art, the claw is also welded with the ratchet wheel ground plate, and the technical defect is similar to that of the first prior art.

The technical scheme that CN 207309807U discloses is, including ratchet spanner and the chuck that corresponds the cooperation with ratchet spanner, the chuck is equipped with at least two, and each chuck has the jack catch that is used for cooperating with the valve hand wheel of corresponding model respectively, and ratchet spanner has power take off portion, and each chuck has respectively to be used for with power take off portion spline grafting complex power input part, one of power input part and power take off portion is to the commentaries on classics hole, another is to the commentaries on classics post. This scheme replaces aforementioned two prior art's joint spare through the chuck to set up corresponding chuck according to the model of valve hand wheel, but undoubtedly can increase manufacturing cost, and increased and kept and use the degree of difficulty.

Therefore, the present invention is further developed based on the drawbacks of the above-described techniques.
