Background technology
A large amount of with 500kV typical case substation of State Grid Corporation of China build and put into operation, and floor space is small, and equipment installation is tight
The contradiction that the space for maintenance brought that gathers cannot meet large scale hoisting machinery is more and more prominent.By investigating, in Ultra-high Voltage Substations
Narrow space is broadly divided into following a few classes, and 500kV battery limits GIS compartment narrow spaces are stone place mat pavement roughnesses, hard
Degree is inadequate, large-scale crane, bucket arm vehicle is caused to be difficult to enter, haulage vehicle can not smoothly pass；220kV is whether opened wide battery limits
Formula or GIS formulas, compact equipment installation, open type phase spacing are only 4m, the high 2.5m of equipment installing base framework, and common hangs
Vehicle, bucket arm vehicle, haulage vehicle are to think to enter safely in the case of not all power failure and safety work difficulty is high；Equally
110kV battery limits, 35kV battery limits, the space of main transformer battery limits are just more narrow, and common working truck is difficult to meet the requirements.
Therefore, it develops with being of great immediate significance using the combined type hoisting machinery for meeting Ultra-high Voltage Substations narrow space.
Discovery is investigated by us, meets the narrow space combined type hoisting machinery mesh of super ultra-high voltage transformer station electric operating
Preceding there are no companies in worldwide to be related to, Italian jekko, Japanese unic, preceding field, and R ＆ B etc. have miniature shoe
Band crane, but function is single, it is impossible to it is used in the narrow space of super ultra-high voltage transformer station electric operating.And combined type lifting from now on
The intelligent and multi-functional of machinery can be development trend, and function is more and more perfect, and operation is more and more reliable, can realize long-range distant
Control operation and remote control, safety also greatly improve.
Several equipment integrations of operation are needed during Ultra-high Voltage Substations upkeep operation at present, transport vehicle handle is needed accordingly to set
Received shipment is defeated to designated position, needs crane that equipment is lifted to specified altitude assignment, then also needs to the manned progress of high-altitude operation vehicle
Installation and upkeep operation, work progress need device category more, and cooperation is relative complex.
The patent document of publication number CN106241678A discloses a kind of substation's livewire work and walks lifting with crawler self
Device, the crawler-type traveling structure including insulation are provided with scissor-type liter can lift and insulation in crawler-type traveling structure
Structure is dropped, the work bucket structure stood for operating personnel, crawler type can be slidably provided on scissor type elevating structure
Multiple branch that can be rotated around corresponding vertical axes and stretch out crawler-type traveling structure and flexible change height are provided on walking structure
Support structure is provided with cat ladder structure upwardly extend and insulation in crawler-type traveling structure.
The patent document of publication number CN103056866A discloses a kind of substation's hot line robot, and control system is whole
By wirelessly carrying out signal transmission, so as to improve the safe operation performance of operating personnel.It includes working machine and remote control refers to
Wave vehicle, working machine is mainly made of dynamical system, executing agency, hydraulic control system and control system, executing agency mainly by
Walking mechanism, revolving platform, the hoistable platform of more piece insulation arm composition, six-freedom hydraulic mechanical arm are formed, revolving platform peace
In walking mechanism, hoistable platform is connect with revolving platform, and six-freedom hydraulic mechanical arm is connect with hoistable platform；Hydraulic pressure control
System processed includes hydraulic pump, it connect with dynamical system, and hydraulic pump is also connect with the fuel tank in walking mechanism, and hydraulic pump is by dividing
With valve respectively with lower part solenoid directional control valve A groups, central crossover sub, upper dress solenoid directional control valve B groups, mechanical arm hydraulic efficiency servo-valve C
Group and each section insulation arm drive cylinder are connected with rotation motor.
Above two structure is disadvantageous in that：When in face of narrow working space, the continuous adjusting angle of vehicle is needed
Degree, can not ensure the safe and reliable of power output environment.
