Abstract
The utility model relates to a multifunctional examining and repairing device for a super high-voltage isolated knife switch, which is used for installing and repairing power supply equipment. The utility model comprises a bracket, a jack and a main working rod, wherein, the top end of the main working rod is provided with the other main working rod having a top part with a pulley support, and the two main working rods can rotate oppositely. A winch arranged on the bracket is connected with a hook through pulley wheels and lifting ropes arranged on the bracket and the pulley support. The utility model has the advantages of the integration of the multiple functions of hoisting, lifting and maintenance and easy and safe use.
Description
The utility model relates to the multi-functional maintenance device of superhigh pressure isolation switch that usefulness was installed and keeped in repair to a kind of power supply unit.
Maintenance, installation high voltage isolator are a regular job in the substation equipment maintenance and repair work, high pressure is being overhauled, installed to past every high switch, particularly overhaul the GW4-220KV isolating switch, owing to there is not special-purpose service kit, and be subjected to the restriction of job site condition, often to do a large amount of a series of maintenance preparation.Need employ crane (perhaps gin pole and hoisting equipment) as (1); (2) need professional hoisting equipment personnel; (3) power failure expanded range.Consider from security standpoint, overhaul a 220KV disconnecting link, need the contiguous charging equipment that jeopardizes in crane and the hoisting equipment scope of activities is had a power failure; (4) the service work time is long.Before the maintenance disconnecting link,, cause maintenance duration long, cause long-time power failure the user owing to need do a large amount of grid switching operations and safety measure work; (5) isolating switch of maintenance, the operations staff must carry out the grid switching operation (owing to need to enlarge the power failure scope, increased operations staff's power failure operation element amount, and done a large amount of electric grid switching operations that send behind the end-of-job again) of big workload; (6) because maintenance technology falls behind, increased maintenance worker's labour intensity, and caused maintenance worker's technical quality to be difficult to improve, labor productivity is difficult to improve; (7), be to threaten to the safety of job site because job site maintainer, lifting specialty people mixes together, and work is difficult to coordinate.For addressing the above problem, the applicant once applied in 92 years and had authorized ZL92226865.7, can solve the problem in the maintenance process preferably, but needed to change when damaging parts, and comparatively difficulty then seems.
The purpose of this utility model is to provide a kind of multi-functional maintenance device of superhigh pressure isolation switch that can solve the problem that exists in the maintenance process easily.
For achieving the above object, the utility model adopts following technical scheme: it comprises that the bottom has the support of fixed screw, frame bottom is provided with jack, jack top vertical fixing has the work mobile jib, the work mobile jib is provided with two or more vertical with it anchor ears, work mobile jib top is connected with the work mobile jib that another top is a pulley bracket, and two work mobile jibs can rotate relatively, and the winch that is located on the support is connected with suspension hook by pulley, the lifting rope that is installed on support and the pulley bracket.
The utility model has the advantages that collection lifting, lifting, maintenance are multi-functional is one, and (1) can substitute the function of crane (gin pole), has reduced hoisting equipment and lifting personnel's expense; (2) this apparatus for examination and repair is made up of upper and lower Working rack, the centre has one can freely move up and down, the work mobile jib of left rotation and right rotation and lifting strand mill equipment, when installing isolating switch, maintenance only needs this device is fixed on the framework, just can carry out work flexibly and comfortably, as disassembling, assembling and replacing disconnecting link, porcelain vase, pedestal and replacing rolling bearing etc.; (3) because this device has been arranged, can not need to consider to enlarge the power failure scope, only the equipment interval of need maintenance need be had a power failure gets final product, and has shortened the time and the power failure scope that have a power failure so widely, alleviates the workload of operations staff's grid switching operation greatly; (4) this device has been arranged, alleviated maintainer's labour intensity greatly, the darg amount that the past wants many people to do utilizes this device only to need 3-4 people can finish in individual many hours at 4-5, and labor productivity obviously is improved, and has guaranteed the repair quality of disconnecting link; (5) fail safe, the reliability in the work improves greatly.
Fig. 1 is the utility model structural representation;
Fig. 2 is two work of a utility model mobile jib coupling part partial structurtes schematic diagram.
The utility model is described in further detail below in conjunction with accompanying drawing:
It comprises as accompanying drawing 1, shown in 2, the utility model is the pyrometric cone bodily form support (1) that the bottom has fixed screw, (2), frame bottom (10) is provided with jack (6), jack (6) top vertical fixing has work mobile jib (4), work mobile jib (4) is provided with two vertical with it anchor ears (7), the work mobile jib (3) that another top is a pulley bracket is established on work mobile jib (4) top, two work mobile jibs can rotate relatively, be located at winch (5) on the support by being installed in the pulley (11) on support and the pulley bracket, lifting rope (8) is connected with suspension hook (9), and mid-stent is established bracing piece (12).
