Description
Technical field
This utility model relates to a kind of spanner, particularly relates to a kind of tower crane standard knot screw rod special spanner.
Background technology
It is known that, present construction is built building and is all be unable to do without tower crane handling goods and materials, and tower crane is all assembled by a standard knot successively, fastens with screw rod between each standard knot, these screw rods in tower crane running all it may happen that loosen, it is necessary to check at any time and also fastened.But, these screw rods are all larger in size, also tend to require over beat fasten during fastening.And also need to one end when fastening and fix, one end rotates tightens, and two handss to use simultaneously and just can accomplish.And when doing these fastening work, work high above the ground often, so also existing great potential safety hazard.Existing leatherhead, double offset ring spanner cannot be fixed on nut or screw rod head, and tower crane is in high-altitude, and operating surface is narrow and small, cause many bolts and are unable to reach desirable tightness, thus increasing the risk that tower crane collapses.
Utility model content
The purpose of this utility model is in that to provide the tower crane standard knot screw rod special spanner that a kind of can be fixed on nut or screw rod head, not have potential safety hazard in order to overcome the deficiencies in the prior art.Its concrete technical scheme is: tower crane standard knot screw rod special spanner includes with the cylinder of interior hexagonal through hole, handle, handle is fixedly welded on cylindrical outer surface, handle axis is vertical with a plane of interior hexagonal through hole, a through hole it is provided with in handle, this through hole one end communicates with the fastener hole on cylinder, the other end and a screwed hole communicate, one top-fastening rod is set in through hole and fastener hole, its rear is one section of threaded rod, it is connected with the screwed hole on handle by screw thread, the tail end of top-fastening rod has a tappet head, the outer surface of tappet head is fixed with and tightens bar.
In order to prevent top-fastening rod from retreating, having a groove in the middle part of the screw thread bar segment of top-fastening rod, a screw passes the screwed hole on handle and groove apical grafting.
When using this utility model tower crane standard knot screw rod special spanner, first it is enclosed within screw rod head with a tower crane standard knot screw rod special spanner, screw in release handle, rotate tappet head, the head making top-fastening rod presses closer on the side of screw rod head, then tightens the screw on handle, makes spanner be fixed on screw rod head, it is close to tower body by rotation direction, then on tappet head, fastens safety rope cause accident to avoid falling.It is enclosed within nut with another tower crane standard knot screw rod special spanner again, repeats operation above, then just can move or knock rotation tower crane standard knot screw rod special spanner tightening nuts.
Can be seen that from the technical solution of the utility model, owing to can tower crane standard knot screw rod special spanner be fixed on nut or screw rod head by this structure of top-fastening rod, workman can one-handed performance, efficiently avoid the generation of security incident, fully meet the goal of the invention that of the present utility model can be fixed on nut or screw rod head, not have potential safety hazard.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model tower crane standard knot screw rod special spanner.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment 1, referring to accompanying drawing 1, tower crane standard knot screw rod special spanner includes the cylinder 1 with interior hexagonal through hole 2, handle 4, handle is fixedly welded on cylindrical outer surface, handle axis is vertical with a plane of interior hexagonal through hole, a through hole 3 it is provided with in handle, this through hole one end communicates with the fastener hole on cylinder, the other end and a screwed hole communicate, one top-fastening rod 5 is set in through hole and fastener hole, its rear is one section of threaded rod 6, it is connected with the screwed hole on handle by screw thread, the tail end of top-fastening rod has a tappet head 9, the outer surface of tappet head is fixed with and tightens bar 10.In order to prevent top-fastening rod from retreating, having a groove 7 in the middle part of the screw thread bar segment of top-fastening rod, a screw 8 passes the screwed hole on handle and groove apical grafting.
Claims (2)
