Abstract
The utility model discloses a tension cross arm hoisting device which settles the following defects in hoisting the prior tension cross arm: time wasting, labor wasting, and certain safety hazard. The tension cross arm hosting device comprises a power transmission line pole (1) and a pi-shaped portal frame (4). The pi-shaped portal frame (4) is internally provided with two horizontal supporting bolts (5). The bottom end of the pi-shaped portal frame (4) is fixedly connected with a hoop iron (6) which is clamped on the power transmission line pole (1). The two horizontal supporting bolts (5) are lapped on the top end of the power transmission line pole (1). A fixed pulley fixing cantilever beam (11) is fixedly arranged at the right end of the pi-shaped portal frame (4). The fixed pulley fixing cantilever beam (11) is provided with a fixed pulley (7) on which a hoisting rope (8) is arranged. According to the tension cross arm hoisting device, the tension cross arm can be assembled on the power transmission line pole by one person, thereby greatly enlarging safety factor and shortening working time.
Description
Technical field
The present invention relates to a kind of hoisting device, particularly a kind of hoisting device of assembling the strain cross arm on transmission tower.
Background technology
When erecting power transmission lines, need the strain cross arm on the assembling transmission pole, a kind of mode is that two operating personnel climb up transmission pole simultaneously, after carrying out safety measure, lift by crane separately a cross-arm, then after completing mutual aligning on bar, wear bolt and fix; Another kind of mode is on the ground strain cross arm tentatively to be assembled by the ground handling personnel, the cross-under screw is suitably tightened, by lifting in double harness on bar, then firmly raised by two people, after passing from the transmission line masthead, two people lift and hold level with both hands in position, and tighten the screws fixes strain cross arm.This dual mode all must have been coordinated by two staff on bar, and two people operate simultaneously with bar,, because the working space on bar is limited, wastes time and energy and has certain potential safety hazard.
Summary of the invention
The invention provides a kind of strain cross arm hoisting device, solved the problem that existing strain cross arm lifts wasting time and energy of existence and has certain potential safety hazard.
The present invention solves above technical problem by the following technical programs:
A kind of strain cross arm hoisting device, comprise transmission pole and π font portal frame, be provided with two horizontal support bolts in π font portal frame, bottom at π font portal frame is fixedly connected with anchor ear, anchor ear is connected on transmission pole, two horizontal support bolts are overlapped on the top of transmission pole, right-hand member at π font portal frame is fixedly installed fixedly outrigger of fixed pulley, fixedly be provided with fixed pulley on outrigger at fixed pulley, be provided with lifting rope on fixed pulley, one end of lifting rope hangs and is connected to strain cross arm, and the other end of lifting rope is being drawn by the ground handling personnel.
Left end at π font portal frame is provided with lifting hole(eyelet), is provided with the pulley suspension hook in lifting hole(eyelet).
The present invention only needs a people just can assemble strain cross arm on transmission pole, and labour intensity is reduced greatly, and coefficient of safety improves greatly, and the operating time has also shortened.
Description of drawings
Fig. 1 is structural representation of the present invention.
