Description

Insulated Boom Crane

the

technical field

The present invention relates to a kind of lifting equipment for electric power operation, specifically a kind of insulated arm crane.

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.

Most of the existing live working vehicles are insulated high-altitude operating vehicles, and the load capacity of the vehicles is less than 0.5 tons. It is difficult to replace and install heavier electrical components. Especially when working in a substation, even if the maintenance equipment is powered off, there is still high voltage in the surrounding adjacent equipment, and the degree of operation risk is relatively large; at the same time, because the equipment is installed on a fixed bracket, the fixed bracket has a standard height, and the safety distance of the equipment is limited. Strict requirements, the vehicle must pass through the lower part, which requires the vehicle to be small in size, especially the strict height limit, ordinary cranes cannot work without power failure in adjacent intervals; existing insulated aerial work vehicles cannot meet the requirements On-site requirements.

Contents of the invention

The technical problem to be solved by the present invention is to provide an insulated arm crane with large load capacity and high safety protection that can work under live conditions.

In order to solve the above-mentioned technical problems, the insulating arm crane of the present invention includes a vehicle head, wheels, and a vehicle body composed of a frame, and also includes three mutually nested and telescopic insulating arms. The front end of the insulating arm is provided with an insulating hook The two sides of the vehicle frame are provided with retractable hydraulic outriggers, the platform of the vehicle frame is provided with a turntable connected by a slewing mechanism, the turntable is hinged with an insulating arm support, and the insulating arm is installed on the turntable through the insulating arm support; The insulating arm can be driven to swing between the vertical direction and the horizontal direction by an oil cylinder arranged on the turntable; an insulating working bucket that can be operated by a worker is also arranged on the vehicle frame.

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 insulating working bucket is arranged on the front part of the platform of the vehicle frame and is located on the same centerline as the turntable.

The insulating working bucket is detachably installed on the front part of the platform of the vehicle frame.

A weighing sensor and a display are arranged on the vehicle body.

The advantages of the present invention are:

Due to the set of three mutually nested and telescopic insulating arms, the front end of the insulating arm is provided with an insulating hook, which can ensure that the withstand voltage of the whole vehicle reaches 220kv; the arm body has high strength and bending strength, and the maximum lifting capacity can meet User requirements; due to the reasonable setting of the car body structure, fast driving speed and high efficiency of emergency repair work, the telescopic hydraulic outriggers installed on both sides of the frame have fast deployment speed, small footprint, and stable support. The insulated working bucket that can be loaded and unloaded quickly has a large carrying capacity and working height, which meets the requirements of high-altitude operations.

Detailed ways

The insulating boom crane of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in the figure, the insulating arm crane of the present invention includes a vehicle head 1, wheels 2 and a vehicle body composed of a frame 3, and also includes three mutually nested and telescopic insulating arms 4, and the front ends of the insulating arms 4 are arranged There is an insulating hook 5, that is, a straight-arm telescopic arm body structure is adopted. The arm body is a high-voltage insulating arm body, and a lifting rope with high-voltage-resistant material and sufficient bending strength is used to make the whole vehicle meet the 220kv high-voltage insulation requirements. The two sides of the vehicle frame 3 are provided with telescopic hydraulic outriggers 6, and the hydraulic outriggers adopt the A-shaped outrigger structure, which are respectively installed in the special chute of the vehicle frame. Under the promotion of the special oil cylinder, the hydraulic outriggers can realize Action; hydraulic support legs 6 are set to four, and every two hydraulic support legs 6 are a pair, and the hydraulic support legs set in pairs are respectively installed on both sides of the front part and both sides of the rear part of the vehicle frame; 3 is provided with a turntable 8 connected by a slewing mechanism 7, an insulating arm support 9 is hinged on the turntable 8, and the insulating arm 4 is installed on the turntable 8 through the insulating arm support 9; the insulating arm 4 can be installed on the The oil cylinder on the turntable 8 is driven to swing between the vertical direction and the horizontal direction, so that the oil cylinder on the turntable 8 can realize the lifting action of the arm body, and the telescopic oil cylinder action in the telescopic arm can realize the telescopic action of the arm body; There is also an insulated working bucket 10 that can enable the staff to operate, which can meet the requirements of personnel for live work; the insulated working bucket 10 is arranged on the front of the platform of the vehicle frame and is located on the same center line as the turntable 8, that is, both are located on the vehicle. The central line of the frame 3 platform width direction, thereby making the operating angle of the operator good, the insulating working bucket 10 is installed on the front of the platform of the vehicle frame in a detachable manner, and the insulating working bucket 10 is carried with the vehicle as an accessory of the vehicle. When it is used, it can be hung on the insulating hook with a special sling.

Furthermore, a load cell and a display can be arranged on the vehicle body, which can display the lifting weight and prevent overloading.
