Abstract
The utility model discloses a dedicated double-shaft wrench which comprises a driving gear shaft, two driven gear shafts meshed with the driving gear shaft, and an external box body. The driving gear shaft and the two driven gear shafts are arranged in the external box body through bearings. The two driven gear shafts are the same in specification and extend out of the external box body in the same direction. Tail ends of the two driven gear shafts are respectively provided with sleeves, same in specification, of nuts used for U-shaped bolts. The driving gear shaft extends out of the external box body in an opposite direction. The tail end of the driving gear shaft is provided with a ratchet handle structure. Further improved, the two driven gear shafts and the sleeves are of an integrated formed structure. The dedicated double-shaft wrench has the advantages of being simple and practical in body structure and free of tedious operation procedures, bringing convenience to actual operation by production workers, and achieving the effects of reducing preplanned production working time and improving preplanned production working efficiency.
Description
Technical field
The utility model relates to the bolted instrument, is specially a kind of special-purpose twin shaft spanner.
Background technology
For a long time, in the high ferro construction bracket prewired all be a very important job.At present, the prewired not full ripe equipment of cover and the specific purpose tool of bracket.The nut that needs alternately to tighten with ratchet spanner U-bolt in the prewired process of bracket, it must cause the moment state of two nuts inconsistent.Alternately tightening specification requirement needs pre-twisting 3 times, causes like this inefficiency.Existing equipment and instrument have not satisfied the demand of prewired job development, have some equipment and instrument must will improve, innovate.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of twin shaft spanner of using, and improves prewired work quality and the efficient of bracket, makes more standardization of bracket production, systematization, safe.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Special-purpose twin shaft spanner, comprise driving gear shaft and two driven gear shafts that mesh with driving gear shaft, with outside box body, described driving gear shaft and two driven gear shafts are connected in the outside box body by bearing, described two driven gear shaft specifications are identical, and same direction is extended outside box body, and end is respectively equipped with the same specification sleeve for the nut of U-bolt; The driving gear shaft rightabout extends outside box body, and is terminal for connecting the ratchet handle structure.
As further improvement, described two driven gear shafts and described sleeve are integral forming structure.
The utilization of the special-purpose twin shaft spanner of the utility model be the gear drive principle.Mainly be to drive two driven gear shafts by a driving gear shaft to rotate simultaneously, when driving gear shaft was rotated counterclockwise, driven pulley will turn clockwise, and then the moment that produces when two sleeves are tightened the nut of U-bolt will be approximately identical.If original technology of alternately tightening is identical for the moment that reaches U-bolt two end nuts, need pre-twisting 3 times but alternately tighten specification requirement, just and this twin shaft spanner only needs can reach original purpose of alternately tightening specification requirement 1 time.
Special-purpose twin shaft spanner and original specification requirement contrast advantage of alternately tightening:
1. physique structure is simple, practical, does not have loaded down with trivial details operation sequence, is convenient to direct labor's practical operation.Simplify the specification requirement of alternately tightening the U-bolt nut in the prewired production, also simplified the technological process of prewired production simultaneously.
2. driven the gear principle of driven gear shaft by driving gear shaft, two nuts of U-bolt are tightened simultaneously in advance, reduced the working time of prewired production, improved the operating efficiency of prewired production, also made prewired production semi-automation go on a new step.
Description of drawings
Fig. 1, be the structural representation of facing of this twin shaft spanner;
Fig. 2, be the plan structure schematic diagram of this twin shaft spanner;
Fig. 3, be the internal gear schematic diagram of this twin shaft spanner.
The specific embodiment
Such as Fig. 1, Fig. 2, special-purpose twin shaft spanner illustrated in Figure 3, comprise driving gear shaft 1 and two driven gear shafts 2 that mesh with driving gear shaft 1, with outside box body 3, described driving gear shaft 1 and two driven gear shafts 2 are connected in the outside box body 3 by bearing, described two driven gear shaft 2 specifications are identical, and same direction is extended outside box body 3, and end is respectively equipped with the same specification sleeve for the nut of U-bolt; Driving gear shaft 1 rightabout extends outside box body 3, and is terminal for connecting the ratchet handle structure.Described two driven gear shafts 2 are integral forming structure with described sleeve.
The above is embodiments of the invention only, is not limited to patent of invention, and for a person skilled in the art, the present invention can have various modifications and variations.Allly within the spirit and principle of invention, any modification of doing, be equal to replacement, improvement etc., all should be included within the claim scope of invention.
Claims (2)
1. special-purpose twin shaft spanner, comprise driving gear shaft (1) and two driven gear shafts (2) that mesh with driving gear shaft (1), with outside box body (3), it is characterized in that: described driving gear shaft (1) is connected in the outside box body (3) by bearing with two driven gear shafts (2), described two driven gear shafts (2) specification is identical, and same direction is extended outside box body (3), and end is respectively equipped with the same specification sleeve for the nut of U-bolt; Driving gear shaft (1) rightabout extends outside box body (3), and is terminal for connecting the ratchet handle structure.
