Description
Technical field
The utility model belongs to the specific purpose tool of demounting bolt or nut, and particularly a kind of box spanner is suitable for dismantling and has fully a plurality of nuts of cap, is particularly useful for dismantling nut, the bolt of nut, bolt and other high large equipment eminence on the oil pumper.
Background technology
The beam pumping unit of petroleum industry belongs to high large equipment, and the nut of general high large equipment eminence all has cap fully.For the beam pumping unit balancing is oil recovery workman's routine work.Because the balance of well pumping unit piece is heavy huge, its set bolt is also relative with nut very big.When the oil recovery workman is to the beam pumping unit balancing at present, the spanner of dismounting, clamp nut all is made up of spanner side and handle, during use spanner is enclosed within on the nut, buttress spanner on the other hand, waving hammer impacts pinch bar on the other hand, make nut unload pine or fastening, finish the adjustment work of balance of well pumping unit piece.Because the beam pumping unit fuselage is tall and big, its nut all has cap fully, and dismounting beam pumping unit balance weight screw bolt and nut belongs to work high above the ground.Health does not have the strong point when working on the balance weight because of the workman stands in again, the high-altitude takes place and falls in article and parts easily in its hand, unload on particularly bolt be equipped with the cap nut time because the spanner below does not have the strong point, it is very dangerous to impact the easy slippage of spanner, and workman's health and equipment are damaged easily.
Summary of the invention
The purpose of this utility model provides a kind of box spanner, and convenient high large equipment uses, and handled easily reduces dangerous.
The present technique solution can reach above-mentioned purpose: a kind of box spanner comprises handle and spanner side, is provided with above spanner side and sets upright tube.
The utility model compared with prior art has following characteristics: with the utility model is that balance of well pumping unit piece or high large equipment are dismantled, clamp nut, and it is simple to connect reliable operation, and hammer force is huge.Because spanner has had the tube of setting upright, when dismounting has the nut that is equipped with cap, make the below of spanner side that the strong point arranged, improved safety coefficient, improved operating efficiency.The utility model is simple in structure, and is easy to process.Can change spanner side and the size of setting upright tube as required, be processed into the box spanner of multiple size, to meet the needs of.
Description of drawings
Accompanying drawing 1 is the front view of the utility model structural representation.
Accompanying drawing 2 is the vertical view of the utility model structural representation.
The specific embodiment
Below in conjunction with embodiment the utility model is done further detailed description: referring to accompanying drawing 1 and accompanying drawing 2, a kind of box spanner comprises handle 1 and spanner side 2, is provided with to set upright tube 3 above spanner side 2.Be used for dismounting when being equipped with the cap nut, will of the present utility modelly set upright tube 3 and spanner side 2 is enclosed within be equipped with on the cap nut.Effect owing to the main bodys of setting upright the nearly equipment of tube 3 cards have played support below, set upright prevents that spanner is loosening, can dismantle the cap nut fully of the superiors like a cork.After dismounting is equipped with the cap nut, with the utility model conversely, makes and set upright tube 3 up, knocking handle 1 unloads pine with clamp nut.During with the utility model dismounting fastening bolt, operate the same.In a word, according to circumstances,, just will set upright tube 3 down, if nut just will be set upright tube 3 up less if nut is many.
