Description
Technical field
The present invention relates to the hanging device technical field, relate in particular to lifting appliance on a kind of replacing electrical equipment bar.
Background technology
Along with the development of electric utility is rapid, society increases severely to the demand that supplies power consumption, particularly the disconnector in power plant, the 110kV of substation and the following change primary equipment, press change, rheology increase-volume, remodel, transformation task is heavy, maintenance workload is especially big.The wooden gin pole lifting commonly used of this kind equipment is changed in past construction, and this height of gin pole and benzene is heavy is when the operation personnel hold up it or fell when moving; Not only labour intensity is big, and inefficiency is careless slightly; The danger that touches other charging equipment is arranged at any time, thereby bring hidden danger to safety in production.Chinese patent CN201321352 discloses the special-purpose lifting appliance of a kind of electrical equipment; Comprise winch and support; It is characterized in that: constitute but said support mainly overlaps, is supported on the transposition arm that overlaps on the turntable of top on the cape top by suspension rod pillar, sleeve on the cape top of suspension rod pillar upper end, pulley is housed, after two pulleys are successively passed in the steel rope outer end of said winch near the two ends of said arm respectively; Pass through suspension hook again, be fixed on an end of arm.The special-purpose lifting appliance of this electrical equipment is applied in substation's installation and maintenance; Not only solved and used mechanical crane to need large-scale operational outfit power failure phenomenon; And played the inaccessible position of mechanical crane with highly the installation fill up; Avoided the hidden danger of using wooden mast lifting appliance to cause with manpower, thus reach electrical production safely, save time, laborsaving, efficient, purpose of energy saving.In China; Because urban infrastructure is relatively backward, the urban distribution network line construction also is in a development phase, and the urban construction of novelization is netted the electric power circuit pipeline that goes underground with the city; And also there is a large amount of aerial lines in the old town in some city; This has brought some practical difficulties for the maintenance of band point, and in some hot line work service works, there am certain degree of difficulty in we when finding electrical equipment such as the special-purpose lifting appliance charged for replacement of this electrical equipment disconnecting link switch, voltage transformer; On old town or many loop lines road, can not use the bucket arm vehicle direct operation especially; Use the special-purpose lifting appliance of this electrical equipment also to receive the restriction of working space, and the special-purpose lifting appliance complex structure of this electrical equipment, cost of manufacture is high.
Summary of the invention
The objective of the invention is to overcome existing above-mentioned deficiency in the prior art, and provide a kind of simple in structure, cost of manufacture is low, and does not receive lifting appliance on the bar of working space restriction.
Purpose proposed by the invention can realize through following technical scheme: lifting appliance on the bar; Comprise lifting rope, suspension hook, assembly pulley and support; Described support is provided with the connecting device affixed with electric pole; Described connecting device by two pairs be arranged on up and down be connected with on the vertical framework chain hold regulating control tightly and the chain bayonet socket constitutes, described assembly pulley is arranged on the lower end of support.
Said support is mutual horizontal strut connected vertically with vertical framework and is connected the A-frame that both brace constitutes.
The vertical framework of described support is provided with arc pallet.
Described assembly pulley is for walking three assembly pulleys.
Described support is an insulating support.
We have contrasted the performance of various materials in order to guarantee on the bar to have enough tensile strengths and dielectric strength by lifting appliance in the present invention, have selected the pulling square tube and the board making support of high strength epoxy resin fibrous glass for use.For between the limited distance that lifting appliance on the bar is installed in electrical equipment that need to change and circuit cross-arm, and be convenient to the lifting operation, we have adopted the triangular structure Design and Machining that can be fixed on the cement electric pole.Upending frame adopts the anchor ear chain to be connected with electric pole, up and down twice.The position that the electrical equipment of changing is as required installed; A single-wheel insulation coaster is installed in the rear end of lifting appliance spider on bar; At front end a three-wheel insulation coaster is installed, three-wheel insulation ass annulus constitutes through lifting rope connection two-wheeled insulation movable block walks three assembly pulleys.The operating personnel steps between bar to the equipment and cross-arm that need to change, lifting appliance on the first mounting rod, and the electrical equipment that the operating personnel will change on the bar is then tied up; And be fixed on the suspension hook of lifting appliance on the bar, the lifting rope of lifting appliance on the Ground Operation personnel tie rod makes on the zero load fixing old support that is positioned at exchange device more of equipment; The fixing old support of operating personnel's releasing equipment on the bar; The Ground Operation personnel slowly put down used equipment and the fixing old support of equipment, and new installation and new installation fixed support are hung in recurrence, and new installation fixed support and new installation are installed; Accomplish and change operation, lifting appliance on the relieving rod.
The present invention compared with prior art has following beneficial effect: rational in infrastructure simple, cost of manufacture is low; And not limited by working space; Lifting appliance light weight on this bar, good mechanical property, dielectric strength height can make the instrument total quality little; Be easy to carry, alleviated operating personnel's labour intensity.
