Abstract
The invention discloses a tensioning resistant cross arm lifting machine which solves the problems that an existing tensioning resistant cross arm is time-wasting and labor-wasting in lifting and has certain potential safety hazards. The tensioning resistant cross arm lifting machine comprises an electricity transmitting pole (1) and a pi-shaped portal frame (4). Two horizontal pillar bolts (5) are arranged in the pi-shaped portal frame (4). An anchor ear (6) is fixedly connected with the bottom end of the pi-shaped portal frame (4). The anchor ear (6) is clamped on the electricity transmitting pole (1). The two horizontal pillar bolts (5) are in lap joint with the top end of the electricity transmitting pole (1). A fixed pulley fixing outrigger (11) is fixedly arranged at the right end of the pi-shaped portal frame (4). A fixed pulley (7) is arranged on the fixed pulley fixing outrigger (11). A lifting rope (8) is arranged on the fixed pulley (7). A tensioning resistant cross arm can be assembled on the electricity transmitting pole only by one person, a safety coefficient is greatly improved, and working time is shortened.
Description
Technical field
The present invention relates to a kind of hoisting device, particularly a kind of hoisting device of assembling the strain insulator cross-arm on the transmission tower.
Background technology
When erecting power transmission lines, need the strain insulator 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 a cross-arm separately, after bar is finished mutual aligning, wear bolt then; Another kind of mode is on the ground the strain insulator cross-arm tentatively to be assembled by the ground handling personnel, the cross-under screw is suitably tightened, by lifting in double harness on the bar, firmly raised by two people then, after passing from the transmission line masthead, two people lift and hold level with both hands in position, and tighten the screws fixes the strain insulator cross-arm.This dual mode all must be cooperated to finish by two staff on the bar, and two people operate simultaneously with bar, because the working space on the bar is limited, wastes time and energy and has certain potential safety hazard.
Summary of the invention
The invention provides a kind of strain insulator cross-arm hoisting device, solved the problem that existing strain insulator 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 insulator cross-arm hoisting device, comprise transmission pole and π font portal frame, in π font portal frame, be provided with two horizontal support bolts, bottom at π font portal frame is fixedly connected with anchor ear, anchor ear is connected on the transmission pole, two horizontal support bolts are overlapped on the top of transmission pole, right-hand member at π font portal frame is set with fixedly outrigger of fixed pulley, fixed pulley fixedly outrigger is provided with fixed pulley, fixed pulley is provided with lifting rope, one end of lifting rope hangs and is connected to the strain insulator 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 labour intensity be reduced greatly at transmission pole assembling strain insulator cross-arm, 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.
