Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:
A kind of down conductor tractor to shown in Figure 4, comprises retractor body 2 like Fig. 1; Retractor body 2 comprises ratchet-type spooler 22; Ratchet-type spooler 22 lower ends are connected with universal hanging head 21, are provided with steel wire rope 23 in the ratchet-type spooler 22, and steel wire rope 23 other ends are connected with U type ring 24; This down conductor tractor also comprises three usefulness spanners 1; Three usefulness spanners 1 comprise interior four rib spanners 13, and interior four rib spanners 13 are in transmission connection with ratchet-type spooler 22, and interior four rib spanners 13 rear ends are fixedly connected with ground connection yoke plate adjustment spanner 12; Ground connection yoke plate adjustment spanner 12 rear ends are fixedly connected with double offset ring spanner 11, and double offset ring spanner 11, ground connection yoke plate adjustment spanner 12 and interior four rib spanners 13 are structure as a whole; Said universal hanging head 21 lower ends are connected with and promote connector 3; Promote connector 3 upper ends and have mount hole 31; Promote connector 3 and be connected with universal hanging head 21, promote connector 3 lower ends and have hook 33, promote connector 3 lower ends and have U type groove through mount hole 31; U type channel opening is downward, promotes connector 3 middle parts and also has initialize operation hole 32.
Embodiment recited above describes the preferred implementation of the utility model; Be not that design and scope to the utility model limits; Under the prerequisite that does not break away from the utility model design concept, common engineers and technicians make the technical scheme of the utility model in this area various modification and improvement all should fall into the protection range of the utility model; The technology contents that the utility model is asked for protection all is documented in claims.
The utility model is used to draw down conductor, can also implementation tool between dismounting flexibly, make brief of the introduction in the face of its part down:
1. steel wire rope:
Through down conductor sink being promoted force measurement F=113.3kg, requiring for the load of steel wire rope is T >=2F=226.6kg.
Ratchet-type spooler steel wire rope load intensity is directly selected for use the ratchet-type spooler to carry steel wire rope and is not only satisfied the security performance requirement generally more than 1 ton, can also reduce the tool processes production process.
