Abstract
The utility model discloses foldable high strength special spanner belongs to mechanical tool technical field. The foldable handle can be unfolded around a pin shaft, the length of an arm of force is increased, and the labor-saving effect is achieved.
Description
The collapsible high strength special spanner of the utility model relates to the technical field of machine tool.
It is connected mode mechanically commonly used that bolt connects, and the mounting or dismounting of nut and fastening are all arranged in machinery installation, dismounting and maintenance process, and under multiple situation, the pre-fastening moment that the bolt connection request is certain.Install at derrick crane, need in dismounting and the maintenance process high-strength bolt of a large amount of standard knots is installed and removed and fastening, and pre-fastening moment that need be very big, adopt common special-purpose wrench to be difficult to the pre-fastening moment that reaches required, often need to adopt boosting-rod, at present, what the workman used always in the tower machine disassembly process is the common special-purpose wrench of steel pipe socket, because tower machine mounting or dismounting belong to work high above the ground, and boosting-rod do not have with wrench and fixedlys connected, and increased danger, simultaneously, because the space is restricted, move inconvenience, caused labour intensity big, inefficiency falls flat again.Therefore need a kind ofly can carry out fastening, mounting or dismounting to bolt smoothly, and make things convenient for the workman to operate as much as possible, reduce labour intensity and guarantee that safe instrument just seems particularly important.
The collapsible high strength special spanner of the utility model just provides a kind of arm of force and can regulate, safe in utilization convenient, reliable for effect high strength specific purpose tool.
The collapsible high strength special spanner of the utility model has sleeve (1), fixed handle (2), folding handle (3), bearing pin (4) to form, its middle sleeve (1) can be according to nut specification and requirement of strength processing, end with fixed handle (2) welds again, the inside of fixed handle (2) is in the U type groove, be connected with fixed handle by bearing pin (4), folding handle can launch around bearing pin, thereby reaches the purpose of the elongation arm of force, folding handle can be two joints or three joints as required, even more piece more.
As Fig. 1 is the structural representation of the collapsible high strength special spanner of the utility model.
The embodiment of the collapsible high strength special spanner of the utility model is as follows: when carrying whole the folding of folding handle (3) entered in fixed handle (2) groove, during normal the use, the size and the working space situation that connect desired pre-fastening moment according to bolt are selected suitable arm of force length, it is the expansion joint number of folding handle (2), on folding handle, impose less power, just can obtain bigger moment, if required pre-fastening moment is less, then do not need folding handle (3) is launched, directly go up the application of force and get final product at fixed handle (2).
The collapsible high strength special spanner of the utility model is selected to mounting or dismounting, fastening bolt with same size connects, and is easy to carry, need not aid during use, and laborsaving, efficient, reliable, when frequency of utilization is high, its advantage will be more obvious.
Claims (2)
- (1) the collapsible high strength special spanner of utility model, it is characterized in that this wrench is made up of sleeve (1), fixed handle (2), folding handle (3), bearing pin (4), sleeve (1) and fixed handle (2) welding, folding handle (3) is connected by bearing pin (4) with fixed handle (2), and is installed on the inside of fixed handle.
- (2), it is characterized in that folding handle (2) can rotate and launches from fixed handle (2) inwall around bearing pin (4) according to the described collapsible high strength special spanner of claim (1).
