Description
Technical Field
The invention relates to electric power operation hoisting equipment, in particular to an insulating boom crane.
Background
At present, with the development of economic construction in China, the requirement on power supply is higher and higher, a live working mode is required to be adopted to solve the problem of power maintenance, and the economic loss caused by power failure is reduced.
Most of existing live working vehicles are insulated overhead working vehicles, the vehicle load capacity is below 0.5 ton, and heavy electrical components are difficult to replace and install. Particularly, when a transformer substation operates, even if maintenance equipment is powered off, high voltage still exists in adjacent equipment around the transformer substation, and the degree of operation danger is relatively high; meanwhile, the equipment is arranged on the fixed support, the fixed support has standard height, and the safety distance of the equipment has strict requirements, so that the vehicles pass through the lower part, the overall dimension of the vehicles is required to be small, particularly the height is strictly limited, and the common crane cannot operate under the condition that the adjacent intervals are not powered off; the existing insulating overhead working truck can not meet the field requirement.
Disclosure of Invention
The invention aims to provide an insulating arm crane which can work under the condition of electrification and has large carrying capacity and high safety protection.
In order to solve the technical problem, the insulated arm crane comprises a crane head, wheels, a crane body consisting of a frame and three sections of mutually nested and telescopic insulated arms, wherein the front ends of the insulated arms are provided with insulated lifting hooks; telescopic hydraulic support legs are arranged on two sides of the frame, a rotary table connected through a swing mechanism is arranged on a platform of the frame, an insulating arm support is hinged to the rotary table, and the insulating arm is mounted on the rotary table through the insulating arm support; the insulating arm can swing between the vertical direction and the horizontal direction under the driving of an oil cylinder arranged on the rotary table; the frame is also provided with an insulating working bucket which can be operated by workers.
The hydraulic support legs are four in number, and every two hydraulic support legs are respectively arranged on two sides of the front portion and two sides of the rear portion of the frame in pairs.
The insulating working bucket is arranged at the front part of the platform of the frame and is positioned on the same central line with the rotary table.
The insulating working bucket is detachably arranged at the front part of the platform of the frame.
And the vehicle body is provided with a weighing sensor and a display.
The invention has the advantages that:
because three sections of the telescopic insulating arms are nested with each other, and the front ends of the insulating arms are provided with insulating hooks, the voltage resistance of the whole vehicle can be ensured to reach 220 kv; the arm body has high strength and large bending strength, and the maximum lifting capacity can meet the requirements of users; the telescopic hydraulic support legs arranged on the two sides of the frame are high in unfolding speed, small in occupied area and stable in supporting, and the insulating working bucket which is arranged on the frame and can be quickly assembled and disassembled has large bearing capacity and working height, so that the requirement of high-altitude operation is met.
