Fall phenomenon, circuit O＆M unit will mend the cut-out bolt that removable falls again every year.During dress is mended, staff first has to
Stepped on by climbers at bar to cross-arm, for common spanner when installation fastens cut-out bolt, staff wants two hands respectively to be pulled by one
Hand, one is served only for fixed cut-out bolt upper end nut, and one is served only for tightening cut-out bolt lower end.
Because king-bolt and cut-out bolt arrangement are close, spanner is difficult to rotate, and installation cut-out bolt efficiency is very low, while
High-altitude long working extremely expends muscle power.
Utility model content
In order to solve problem of the prior art, the utility model embodiment provides a kind of cut-out bolt fastening combination and pulled
Hand.The technical scheme is as follows：
On the one hand, a kind of cut-out bolt combined fastening wrench, including back-up wrench and spanner；Back-up wrench includes solid
Determine head and torque arm, gland is flattened cylindrical shape, and torque arm is arranged on gland periphery, and gland center is provided with hexagon ring, hexagonal
Hole internal diameter is consistent with the nut external diameter for cutting off bolt；Spanner has and back-up wrench identical structure, on spanner
Torque arm length is more than the torque arm length on back-up wrench, and Anti-slip cover is provided with the torque arm of spanner.
Further, torque arm quantity >=3 on back-up wrench.
Specifically, angle is 120 ° between torque arm on back-up wrench.
Further, torque arm quantity >=3 on spanner.
Specifically, angle is 120 ° between torque arm on spanner.
Further, Anti-slip cover is made of plastics or rubber.
Further, antiskid particles and/or skid resistance strip are provided with Anti-slip cover.
Further, back-up wrench and spanner are made of metal.
The beneficial effect brought of technical scheme that the utility model embodiment provides is：Cut-out spiral shell provided by the utility model
Bolt combined fastening wrench, using cylinder design, space needed for work is small；Can be by the continuous rotational fastener of torque arm, without again
Adjust rotation position；Hexagon ring is close to cut off bolt corner angle, does not damage bolt corner angle；One-hand operation during work, is easy to both hands
Rotation is alternately installed, and saves manpower, and installation effectiveness is high.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
The accompanying drawing to be used is briefly described, it should be apparent that, drawings in the following description are only some realities of the present utility model
Example is applied, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to these accompanying drawings
Obtain other accompanying drawings.
Fig. 1 is the structural representation of back-up wrench 1 in cut-out bolt combined fastening wrench provided by the utility model；
Fig. 2 is the structural representation of spanner 2 in cut-out bolt combined fastening wrench provided by the utility model.
Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Type embodiment is described in further detail.
It is a kind of embodiment of cut-out bolt combined fastening wrench provided by the utility model as illustrated in fig. 1 and 2, including
Back-up wrench 1 and spanner 2.
Back-up wrench 1 includes gland 11 and torque arm 12, and gland 1 is flattened cylindrical shape, and torque arm 12 is arranged on gland
11 peripheries, the center of gland 11 are provided with hexagon ring 13, and the internal diameter of hexagon ring 13 is consistent with the nut external diameter for cutting off bolt.Back-up wrench
3 torque arm 11 are installed, angle is 120 ° between each torque arm 11 on 1.The torque arm 11 installed on back-up wrench 1 can also be it
His quantity, such as four or six, the utility model is not especially limited to this.
Spanner 2 has and the identical structure of back-up wrench 1, including gland 21 and torque arm 22, and gland 21 is flat
Cylindrical shape, the center of gland 21 are provided with hexagon ring 23, and the internal diameter of hexagon ring 23 is consistent with the nut external diameter for cutting off bolt.Gland
3 torque arm 22 are installed in 21 peripheries, and angle is 120 ° between each torque arm 22.The torque arm 21 installed on spanner 2 can also be
