Abstract
The invention discloses a power transmission line lifting device. The power transmission line lifting device comprises a sliding mechanism and a man-carrying platform. A pull rope is arranged between the sliding mechanism and the man-carrying platform, the upper end of the pull rope is fixed to a left baffle and a right baffle of the sliding mechanism, and the lower end of the pull rope penetrates through a second pulley and a third pulley of the man-carrying platform in sequence to be fixed to a drum of a winch. The sliding mechanism and the man-carrying platform are arranged separately, so that it is only needed to move the sliding mechanism to a position where working is needed and then connect the man-carrying platform to the sliding mechanism, and then harm to the man-carrying platform and workers in the moving process is avoided; besides, the function of automatic lifting of the man-carrying platform and the sliding mechanism is achieved through a motor, so that working efficiency is improved.
Description
Technical field
The present invention relates to power industry Maintenance of Electric Transmission Line, maintenance of equipment technical field, particularly relate to a kind of transmission line lowering or hoisting gear.
Background technology
Transmission line wire uses coaster during upkeep operation usually, colligation one section of rope on coaster, the free end of rope controls the sliding speed of coaster by the artificial pulling of staff to rope on shaft tower or on bottom surface.If two shaft tower differences in height have barrier to deposit comparatively greatly or on transmission line wire, then the bad control of the speed of coaster, has had influence on the personal safety of staff in coaster, also can bring hidden danger to site safety work.
Summary of the invention
During upkeep operation, there is safety hazard when coaster moves on transmission line wire for solving in the present invention, be unfavorable for the problem of site safety work and propose a kind of transmission line lowering or hoisting gear on transmission line wire.The present invention for the taked technical scheme that solves the problem is: a kind of transmission line lowering or hoisting gear, comprise slide mechanism, manned platform, wherein slide mechanism comprises " n " type framework, " n " type framework is fixed with and drags rope, horizontally disposed transverse axis is fixed with between the left arm and right arm of " n " type framework, transverse axis is rotatably connected to the first pulley, described first pulley is positioned at " n " type framework, right baffle-plate and right baffle plate is rotatably connected to respectively in the lower end of the lower end of left arm and right arm, the lower end of right baffle-plate and right baffle plate is bolted to connection, corresponding circular hole is provided with on right baffle-plate He on right baffle plate, the top of described manned platform is provided with tensioned lines, support, winding plant, connector is fixed with at the free end of tensioned lines, connector is rotatably connected to the second pulley, the 3rd pulley is rotatably connected at cradle top, 3rd pulley is positioned at the top of winding plant, and when tensioned lines tensioning, the height of the 3rd pulley is greater than the height of the second pulley, between slide mechanism and manned platform, be provided with stay cord, the upper end of described stay cord is fixed on right baffle-plate and right baffle plate through circular hole, and the lower end of stay cord is fixed on the rotating cylinder of winding plant through the lower limb of the second pulley, the top edge of the 3rd pulley successively.
Further, " n " type framework is fixed with a left side drag rope and the right side drag rope.
Further, the corner, top of described manned platform is equipped with tensioned lines, and the free end of tensioned lines links together and is then fixedly connected with connector.
Slide construction is separated setting with manned platform by the present invention, again manned platform is connected on the sliding mechanism after so only slide mechanism first need being moved to the position needing work, thus avoid in moving process the harm that manned platform and staff bring, achieved the function of automatic lifting on the other hand between manned platform and slide mechanism by motor, improve operating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of slide mechanism.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As depicted in figs. 1 and 2, a kind of transmission line lowering or hoisting gear, comprise slide mechanism, manned platform 15, wherein slide mechanism comprises " n " type framework 18, " n " type framework 18 is fixed with a left side and drags rope 3 and rope 4 is dragged on the right side, horizontally disposed transverse axis 19 is fixed with between the left arm 16 and right arm 2 of " n " type framework 18, transverse axis 19 is rotatably connected to the first pulley 17, described first pulley 17 is positioned at " n " type framework 18, right baffle-plate 21 and right baffle plate 20 is rotatably connected to respectively by bearing pin 5 in the lower end of the lower end of left arm 16 and right arm 2, right baffle-plate 21 is connected by bolt 6 with the lower end of right baffle plate 20, corresponding circular hole 7 is provided with on right baffle-plate 21 He on right baffle plate 20, the top of described manned platform 15 is provided with four tensioned lines 14, support 11, winding plant 12, described four tensioned lines 14 are separately positioned on the corner at the top of manned platform 15, the free end of four tensioned lines 14 links together and is then fixed with connector 13, connector 13 is rotatably connected to the second pulley 9, the 3rd pulley 10 is rotatably connected at support 11 top, winding plant 12 is positioned at the below of the 3rd pulley 10, and when tensioned lines 14 tensioning, the height of the 3rd pulley 10 is greater than the height of the second pulley 9, stay cord 8 is provided with between slide mechanism and manned platform 15, the upper end of described stay cord 8 is fixed on right baffle-plate 21 and right baffle plate 20 through circular hole 7, and the lower end of stay cord 8 is fixed on the rotating cylinder of winding plant 12 through the lower limb of the second pulley 9 and the top edge of the 3rd pulley 10 successively.
The present invention in use, first bolt 6 is screwed out right baffle-plate 21 and right baffle plate 20, right baffle-plate 21 and right baffle plate 20 is rotated respectively to both sides, pulley 17 is placed on transmission line wire 1, then precession right baffle-plate 21 and right baffle plate 20, the upper end of stay cord 8 is tied up on right baffle-plate 21 and right baffle plate 20 through in circular hole 7, allow the staff on ground or on steel tower pull a left side and drag rope 3 and rope 4 is dragged so that slide mechanism is moved to service position in the right side, then stay cord 8 lower end is fixed on the rotating cylinder of winding plant 12 through the lower limb of the second pulley 9 and the top edge of the 3rd pulley 10 successively, staff in manned platform 15 only needs the switch of operating electrical machines 12, just can control manned platform 15 to be freely elevated.
