The specific embodiment
Fig. 1～Fig. 6 illustrates a kind of back-slide continuous operation wrench, comprise handle, the dop of suit threaded connector, it is characterized in that described dop is arranged to sleeve shaped band ratchet adapter head 1, its central authorities are the adapter structure of suit threaded connector, and the outside is a ratchet 12, aforementioned adapter structure is suit through hole, indent sleeve or the plush copper of mating with threaded connector, in the present embodiment, adapter structure is a suit through hole 11, and suit through hole 11 can make multiple shape according to threaded connector suit position profile.Above-mentioned handle 21 connects cylindrical shape ratchet sleeve 2 in its end one, above-mentioned band ratchet adapter head 1 is inlaid in the above-mentioned cylindrical shape ratchet sleeve 2 to be slidingly matched, one port of cylindrical shape ratchet sleeve 2 is provided with along end face ring week boss 22 of extension radially, be provided with 1～2 by the fixing ratchet 4 of hinge 3 in that ring is corresponding with ratchet 12 positions on all boss 22, be provided with 2 ratchets in the present embodiment, the ratchet back side is provided with the roof pressure torsion spring 5 of the roof pressure pawl back of the body, roof pressure torsion spring 5 has adopted the cylinder torsion spring, in the actual fabrication, roof pressure torsion spring 5 is fixedly mounted on the torsion spring seat 6 that is arranged on all boss 22 of ring; On the sidewall of cylindrical shape ratchet sleeve 2 with the ratchet 4 corresponding ratchet windows 23 that have, the reciprocal rotation of the cylindrical shape ratchet sleeve 2 that the ratchet 4 that is articulated in hinge 3 drives with handle, its pawl point 41 is by ratchet window 23 or insert in the teeth groove 13 of ratchet the block ratchet or withdraw from teeth groove 13 and slide along the ratchet back of tooth; Be provided with along the junction along up and down two annular end corresponding with cylindrical shape ratchet sleeve 2 in two annular end up and down of band ratchet adapter head 1 and encircle all slideways 81,82 up and down, plurality of balls 7 is arranged continuously and is inlaid in the slideway.This slideway roll structure can be connected with the cylindrical shape ratchet sleeve by band ratchet adapter head, and it is flexible to make the cylindrical shape ratchet recover when sliding rotation again.
Above-mentioned band ratchet adapter head 1 is casting integrated or the assembly that is made of ratchet and removable adapter head.Adapter head is made independently interchangeable adapter head, and easy disassembly is used, and reduces maintenance cost.Be provided with 2 ratchets and supporting torsion spring thereof in this example, torsion spring seat, hinge and ratchet window; Ratio adopts 1 ratchet to have stronger brake force, work is more reliable and more stable.
The course of work of the present invention and principle:
Back-slide continuous operation wrench provided by the invention is to utilize ratchet and click-fit to realize the principle of unidirectional rotation intermittent movement, realizes the back-slide continuous operation of spanner with simple structure.Fig. 3 illustrates structural relation and the operation principle of the present invention under application of force duty.As shown in the figure, in this example, the hook tooth crown of the ratchet 12 of band ratchet adapter head 1 be counterclockwise towards, when operating personnel will be sleeved on the threaded connector (as nut of nut or bolt etc.) with the suit through hole 11 of ratchet adapter head 1, and when pulling handle 21 cylindrical shape ratchet sleeve 2 being rotated in a clockwise direction, ratchet 4 is under the roof pressure of the roof pressure torsion spring 5 that kinetic energy is provided, live ratchet along block in the inclined-plane insertion teeth groove 13 of the hook tooth back of tooth, at this moment, band ratchet adapter head 1 does not have relative motion with cylindrical shape ratchet sleeve 2, spanner is in running order, pulls down in operating personnel's the application of force, and threaded connector will rotate with handle and rotate to an angle; Ratchet returned sliding status architecture schematic diagram when Fig. 4 was this spanner revolution, when operating personnel pull handle 21 cylindrical shape ratchet sleeve 2 are turned round in the counterclockwise direction, ratchet 4 pawl points 41 lift the position of moving to shown in Figure 4 along the back of tooth inclined-plane of ratchet, promptly withdraw from and form the slippage state by teeth groove 13, at this moment, band ratchet adapter head 1 is done relative motion with cylindrical shape ratchet sleeve 2, will continue with the revolution of handle 21 to slide certain angle of revolution along the ratchet back of tooth.Pull handle 21, repeat aforesaid operations, until the threaded connector completed loading.In the practical operation, the anglec of rotation of pinch bar 21 is decided by working environment and condition of work, and rotation angle range is not limit.
In sum, in loading and unloading during threaded connector, no matter machinery or manpower as long as pull handle 21, just the ratchet 1 and the cylindrical shape ratchet sleeve 2 of band ratchet adapter head 1 are synchronized with the movement, are necessarily finished loading onto or unloading of threaded connector in the rotation angle range.
If the oppositely operation of loading and unloading threaded connector, as long as with 180 ° of the whole upsets of above-mentioned spanner, as shown in Figure 5, it is reverse to be equivalent to the ratchet gear teeth, promptly the hook tooth crown be clockwise towards, ratchet 4 also be reverse, as shown in Figure 6.When pulling handle 21 cylindrical shape ratchet sleeve 2 is rotated in the counterclockwise direction, its operation principle is identical with the operation principle of the above-mentioned spanner that do not overturn, and this does not give unnecessary details, and different is that the threaded connector direction of rotation that is applied is opposite.
The end of pinch bar 21 can link with mechanical device, as hydraulic means etc.Substitute the part manpower with mechanical device, it is more convenient to work, and efficient can further improve.
The above only is the preferred embodiments of the present invention, is not shape material of the present invention and structure are done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
