Description
Technical field
The present invention relates to a kind of pulley suspension device.
Background technology
The construction of electrical network and development, the client is also more and more higher to the requirement of power quality and interruption duration, especially for Very Important Person, requires to continue reliable power supply.And, for electric power system itself, do not have a power failure or have a power failure and just can obtain maximum economic benefit and social benefit less.Therefore, live line working has become the important means that electric line detects, overhauls, transforms, it is also the extensive common recognition of each power supply administration, it can guarantee device security, improve economy operation of power grid and service quality, for the safe and reliable operation of electric power system has been brought into play very important effect with increasing economic efficiency.
When transmission line charged for replacement suspension insulator, the normal insulation rope sling that adopts is wound around cross-arm tower material as suspension centre.If insulate, rope sling is too short can't reach instructions for use, long words can shorten combinational gap, reduced live line working personnel's safe distance, operating personnel and equipment are existed to potential safety hazard, accident even may occur, cause economic loss and casualties, more be unfavorable for the development of live line working.
Summary of the invention
Given this, the object of the invention be to provide a kind of safe, reliably, pulley suspension suspension centre easily.
For solving above technical problem, technical scheme provided by the invention is, a kind of pulley suspension device is provided, comprises a gusset, on two side plates of this gusset, be installed with respectively a screw rod, every screw rod is parallel to the side plate at this screw rod place, simultaneously, two screw rods at grade, and the equal intersecting lens of vertical biside plate of the axial line of two screw rods, be provided with a link on the right angle lateral surface of gusset, all be connected with angle steel fastener and adjusting nut on two screw rods.
Further, described angle steel fastener comprises a mainboard and the grab vertical with mainboard, on this mainboard, is provided with screw.
Further, described angle steel fastener also comprises a position plate, and this position plate is parallel with mainboard, is provided with a guide slot on position plate.
Preferably, described guide slot is semicircle, and its radius equates with the screw radius, the circle at guide slot place and screw coaxial inner conductor.
Preferably, described adjusting nut is butterfly nut.
Compared with prior art, a technical scheme in technique scheme has following advantage:
Security combination gap when 1, the present invention has guaranteed live line working, improved the safety of live line working personnel and equipment, reduced in a large number operating personnel's labour intensity, shortened the operating time, effectively ensured the efficiency of work.
2, the present invention has adopted two angle steel fasteners, can firmly block the angle steel on the tower material.This angle steel fastener is provided with position plate and guide slot, makes the structure of angle steel fastener more stable.
