The utility model has the advantages of simple and reasonable structure, low manufacture cost, no limit in operating space, light weight, good mechanical performance, high insulating intensity, low mass, easy carrying and reducing the work intensity of operators.
Description
Technical field
The utility model relates to the hanging device technical field, relates 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 is to increasing severely for the demand of 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 mobile, 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: described support mainly is made of the indexable arm that suspension rod pillar, sleeve overlap, are supported on the turntable of cover top, cape top on the cape top of suspension rod pillar upper end, pulley is housed respectively near the two ends of described arm, after two pulleys are successively passed in the steel rope outer end of described winch, 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 and 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, the urban construction of the novelization pipeline that city net electric power circuit gone underground, 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, in some hot line work service works, we find the special-purpose lifting appliance charged for replacement of this electrical equipment disconnecting link switch, there is certain degree of difficulty during electrical equipments such as 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 be subjected to the restriction of working space, and the special-purpose lifting appliance complex structure of this electrical equipment, the cost of manufacture height.
Summary of the invention
The purpose of this utility model is to overcome existing above-mentioned deficiency in the prior art, and provides a kind of simple in structure, and cost of manufacture is low, and is not subjected to lifting appliance on the bar of working space restriction.
The purpose that the utility model proposed can be achieved through the following technical solutions: 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 of upper and lower settings on vertical framework, be connected with chain hold regulating control tightly and the chain bayonet socket constitutes, described assembly pulley is arranged on the lower end of support.
Described 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 to the utility model in order to guarantee on the bar to have enough tensile strengths and dielectric strength by lifting appliance, have selected the pulling square tube and the board making support of high strength epoxy resin glass fibre 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 processing 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 of the electrical equipment installation of changing as required, 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 by lifting rope connection two-wheeled insulation movable block walks three assembly pulleys.The operating personnel steps on bar between the equipment and cross-arm that need to change, lifting appliance on elder generation's mounting rod, the electrical equipment that the operating personnel will need to change on the bar is tied up then, 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, make 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, new installation and new installation fixed support are hung in recurrence, new installation fixed support and new installation are installed, are finished the replacing operation, lifting appliance on the relieving rod.
The utility model 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.
