Problems solved by technology

The construction period of the traditional spanning frame is long, the operation is cumbersome, and it has a great impact on the surrounding facilities. The temporary spanning frame is sometimes not firm, which is likely to bring safety hazards; and the materials used to build the spanning frame cannot be reused, and the economic benefits are poor

Embodiment Construction

[0032] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0033] A mobile fast spanning frame with a structure such as Figure 1~4 Shown, comprise car body, auxiliary frame 4, car body supporting assembly 6, hydraulic lifting platform 7, rotary operation assembly.

[0034] The vehicle body is driven by wheels 13 and includes a cab 1 and a main frame 3 . The driver's cab 1 is located at the front end of the car body and is used to control the overall movement of the straddle frame. The main frame 3 is connected to the rear end of the driver's cab 1 and is a rectangular plate structure.

[0035]The shape of the subframe 4 is basically the same as that of the main frame 3 , the subframe 4 is fixedly arranged on the upper end surface of the main frame 3 , and the hydraulic oil tank 2 is arranged at the front of the subframe 4 . The top surface of the auxiliary frame is embedded with a walking platform 5 . The v...

Abstract

The invention discloses a mobile quick crossing frame which comprises a vehicle body, an auxiliary frame, a vehicle body support assembly, a hydraulic lifting platform and a rotation operation assembly. The vehicle body support assembly comprises four vertical cylinders and two extended vertical cylinders which are arranged below the auxiliary frame and respectively controlled by a lower vehicle control console. The rotation operation assembly comprises a rotation platform, which is hinged with a lower arm frame of a long arm structure. One end, far away from the rotation platform, of the lower arm frame is hinged with a telescopic arm frame. The telescopic arm frame is connected in a hooked mode with a protective rope net through a plurality of transverse swinging rods hinged to the two sides. One end, far away from the lower arm frame, of the telescopic arm frame is hinged with a support arm frame. The crossing frame assembled through a vehicle body carrying machine can quickly and conveniently realize overhead wire crossing in an operation site, and has the advantages of being reasonable in structure, short in construction period, and reusable.

Description

technical field [0001] The invention relates to an auxiliary device used in electric power construction, in particular to a fast spanning frame. Background technique [0002] With the continuous development of the economy, the investment in power construction continues to increase, and the construction of power transmission projects continues to increase. Due to the influence of terrain, landform and line passage, there are more and more phenomena that need to cross houses, roads, railways, docks, bridges and other facilities during line construction. When performing these crossing operations, it is often necessary to perform power outage processing on the crossed distribution lines, and at the same time, it is necessary to cut off roads, railways, etc., which brings great inconvenience to the production and life of customers. [0003] In order not to affect the normal production and life during line construction, at present, the spanning frame is usually built from bottom ...
