Description
Technical field
The utility model belongs to high voltage transmission line tower service hoisting equipment technical field, particularly a kind of electric power angle steel tower auxiliary lifting apparatus.
Background technology
In the process of long-range power transmission, usually need to build large-scale high voltage transmission line tower.When high voltage transmission line tower reconstruction, enlarging, equipment or framing member are changed and keeped in repair, often need from ground toward high voltage transmission line tower top lift instrument, equipment or framing member.Angle steel tower is a modal class high voltage transmission line tower, and angle steel tower major part is made up of angle steel and bolt.Angle steel tower because its anode drop is little, safety performance is high, low cost and be widely used in high-voltage fence conveying.But high-voltage fence needs to be far from the crowd, so the high voltage transmission line towers such as angle steel tower often build the severe isolated area of suburb, farmland, these traffic environments of hillside in.
The tower material of high voltage transmission line tower comprises main material and auxiliary material, no matter is all do not arrange special lifting hanging point on main material or on auxiliary material, and owing to lacking specialized equipment and instrument, installation and service worker can only rely on manually uses rope handling.In order to reduce the friction force between the main material of rope and high voltage transmission line tower or auxiliary material, power supply department technical personnel also adopts to be fixed a fixed pulley and comes erection & lift material or equipment on the main material or auxiliary material of high voltage transmission line tower.When there is no its crane-car and crane, lifting reaches the angle steel of 3m and quality and reaches the devices such as the insulator of 220kg and tension-resistant porcelain bottle manpower all will be leaned on to realize, this just has a lot of restrictions to tower hoisting conveying arrangement, and claimed apparatus can not only be fixed at any angle angle steel also will have the characteristics such as easy transport, lightweight, detachable, safe and reliable, assembling cycle is short.Change along with handling article installation site needs the position repeatedly adjusting fixed pulley, not only brings difficulty to construction, and operation inconvenience, expends man-hour.Simultaneously; owing to repeatedly adjusting the fixed position of fixed pulley; once there is many places fixed pulley attachment point in construction; the main material and auxiliary material of high voltage transmission line tower stay the extruding of multiple screw and abrasion mark; these extruding and abrasion mark can destroy the preservative coat on the main material of high voltage transmission line tower and auxiliary material, the shortening main material of high voltage transmission line tower or the life-span of auxiliary material.
Number of patent application is that the Chinese utility model patent of ZL200720085186.0 discloses a kind of tower head multiple fission conductor bont, this device includes two supporting seats, it is characterized in that being connected by the lead screw assembly of adjustable length between two supporting seats, two supporting seats are equipped with vertical hair thick stick respectively, the lower end of vertical hair thick stick can be connected with insulated hanging pole, and top is connected with the leading screw sleeve be placed in above pedestal.This utility model multiple fission conductor bont and Six-divided conductor hook with the use of, electrified wire can being mentioned, just can carry out without the need to having a power failure the operation changing insulator chain.But this utility model multiple fission conductor bont need with Six-divided conductor hook with the use of, its connect with operating process more complicated, for the aloft work of aerial line, still belong to operation inconvenience.
Main material and the auxiliary material overwhelming majority of angle steel tower are angle steel, and the little but length of the thick size of hem width and limit due to angle steel is comparatively large, thus it is high to cause pulley clamping to fix difficulty.Application number be 201120497208.0 Chinese patent disclose a kind of overhead-groundwire lifter, be made up of pulley, support, strap, bolt.This lifter directly uses Boards wall on tower frame cross beam, although structure is simple, is only fixed on crossbeam angle steel, easily makes angle steel discontinuity and deformation occurs, and clamping on the oblique material in V face time easily along oblique material displacement, heavier load cannot be born.Application number be 89219011.6 Chinese patent disclose a kind of multiplex magnetic hanger, suspended weights can be turned to the grip friction power of hanger to steel part by the permanent magnet component of semiclosed magnetic circuit with having the ㄈ shape steel framework of linking up with handle or the L shape steel part the linking up with handle cam rotary lever construction formed that combines is housed.Its structure simply can hang weight or lifting on the angle steel of vertical, level, inclination, is light and handy cheap manipulative device.But owing to stretching out crossbeam, be subject to the shape restriction that angle steel tower is up-small and down-big, be only applicable to the inner space of angle steel tower cross-arm place and pole formation, sphere of action is less.Application number be 201310416155.9 Chinese patent disclose a kind of hanging method of communication tower frame, its device for carrying out said is made up of pedestal, turntable, hauling rope and the fixed pulley group be fixed on cross-arm, when lifting, two turntables control vertical displacement and horizontal displacement respectively, the method easily performs, but must climb up the position that steel tower retightens fixed pulley place when changing lifting direction, execution efficiency is lower.Dimension, designs a kind of auxiliary lifting apparatus that is scalable and that rotate very necessary.
