the

technical field

The invention relates to a lifting device for live high-altitude work, in particular to an insulated crane capable of manned high-altitude work.

Background technique

At present, with the development of my country's economic construction, the requirements for power supply are getting higher and higher, and it is required to use live working methods to deal with power maintenance problems and reduce economic losses caused by power outages; the existing types of insulating work vehicles include insulating aerial work vehicles Insulation crane and insulation crane are respectively suitable for manned insulated high-altitude operations and insulated lifting operations. Due to the different functions of the vehicles, the electric power department needs to be equipped with two types of vehicles at the same time to carry out full-featured insulated high-altitude operations.

Contents of the invention

The technical problem to be solved by the present invention is to provide an insulated crane capable of manned high-altitude operations that is simple in structure, easy to use, and capable of working at heights directly under electrified conditions.

In order to solve the above-mentioned technical problems, the insulated crane capable of manned high-altitude operation of the present invention includes a vehicle body composed of a headstock, wheels and a vehicle frame, telescopic hydraulic legs are arranged on both sides of the vehicle frame, and the platform of the vehicle frame There is a turntable connected by a slewing mechanism on the turntable, and a boom support is hinged on the turntable. There are three mutually nested and telescopic insulating arms connected to the boom support. The insulating arm can be driven by an oil cylinder set on the turntable. Swing between the vertical direction and the horizontal direction; the front end of the insulating arm is provided with an insulating hook, and the front end of the insulating arm is also provided with a detachable insulating mounting sleeve, and an insulating working bucket capable of carrying people is arranged below the insulating mounting sleeve.

There are four hydraulic outriggers, and every two hydraulic outriggers are respectively arranged in pairs on both sides of the front part and both sides of the rear part of the vehicle frame.

The vehicle frame is also provided with an insulating operation bucket that can be operated by staff.

The insulating operation bucket is installed in the front part of the platform of the vehicle frame in a detachable manner.

Both sides of the insulating mounting sleeve are connected with working bucket arms through pin shafts, and the lower ends of the working bucket arms are hinged on both sides of the upper part of the insulating working bucket.

The advantages of the present invention are:

Based on the insulating crane, the insulating arm body is installed on the turntable of the insulating crane. It adopts a three-section straight arm telescopic structure, which can realize the synchronous expansion and contraction of the three-section arm body under the drag of the insulating traction mechanism. At the same time, the front end of the insulating inner arm The detachable insulated working bucket, on the one hand, makes the arm body high in strength and bending strength, on the other hand, it ensures the withstand voltage of the whole vehicle reaches 220kv; Use requirements, simple structure, not only saves the user's purchase cost, improves the use efficiency of the vehicle, but also is convenient to use and can directly work at heights under live conditions, which meets the multi-purpose needs of users for insulated lifting and insulated high-altitude operations. The scope of application of insulating vehicles.

Detailed ways

The insulating crane capable of manned high-altitude work of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in the figure, the insulated crane capable of manned aerial work of the present invention includes a vehicle head, wheels and a vehicle body composed of a vehicle frame 1, and telescopic hydraulic legs are arranged on both sides of the vehicle frame 1, and the vehicle frame 1 The platform is provided with a turntable connected by a slewing mechanism, and the boom support is hinged on the turntable, and the boom support is connected with three mutually nested and telescopic insulating arms 2, that is to say, the insulating arm 2 passes through the insulating arm. The support is installed on the turntable; the insulating arm 2 can be driven to swing between the vertical direction and the horizontal direction by the oil cylinder arranged on the turntable; the front end of the insulating arm 2 is provided with an insulating hook 3, and the front end of the insulating arm 2 is also provided with a The detachable insulating mounting sleeve 4 is provided with an insulating working bucket 6 capable of carrying people under the insulating mounting sleeve 4. The insulating mounting sleeve 4 is a detachable component, and the insulating mounting sleeve 4 is set on the inner arm. The fastener is installed on the front end of the inner arm of the insulating arm, and the two sides of the insulating mounting sleeve 4 are connected with the working bucket arm 5 through the pin shaft, and the lower end of the working bucket arm 5 is hinged on both sides of the upper part of the insulating working bucket 6, that is to say, the insulation The working bucket 6 is installed on the insulating mounting sleeve 4 through the working bucket arm 5, and the parts are connected by pin shafts. When the workers at heights work in the working bucket, the gravity automatic leveling can be realized. The gravity automatic leveling structure can Automatically level the insulated working bucket with different luffing angles of the arm body.

Said hydraulic supporting legs are set to four, and every two said hydraulic supporting legs are respectively arranged in pairs on both sides of the front part and both sides of the rear part of the vehicle frame. An insulating operating bucket for the staff to operate, which is detachably installed at the front of the platform of the frame.

When the vehicle needs to carry out lifting operations, the insulating mounting sleeve 4, the working bucket arm 5, and the insulating working bucket 6 are not installed, and these parts are fixed on the vehicle body in an integral connection mode, and the vehicle can be insulated and lifted by a special lifting system. heavy work.

When the vehicle needs to carry out manned high-altitude operations, after the insulating installation sleeve 4, working bucket arm 5, and insulating working bucket 6 are connected and fastened as required, personnel can enter the insulating working bucket to carry out manned and insulated high-altitude operations. When working at heights, the vehicle can stop the lifting system for operation through electrical components.
