Rear pull rotary crossing-over frame

Abstract

The invention discloses a rear pull rotary crossing-over frame, which comprises a worktable, a rotating mechanism disposed on the worktable, a rear pull hydraulic mechanism disposed on the rotating mechanism and a support table, wherein the rotating mechanism comprises a rotating platform; the rear pull hydraulic mechanism comprises a rear pull hydraulic cylinder disposed on the rotating platformand an inverted V-shaped network closing arm connected with the rear pull hydraulic cylinder; and the support table is disposed at a free end of the network closing arm. During the installation process, the action is stable and reliable, a jamming phenomenon is not easy to occur, and the structure is stable and reliable; the construction workload is saved, the network closing time is shortened andthe engineering cost is reduced; the repeated adjustment of the two sides during the construction process is prevented; the network closing speed is fast, the mechanical failure rate is low, the network closing time is guaranteed, the network closing boom adopts a lattice structure, the structure is stable, and network closing protection is carried out through a hard network closing holding pole,in comparison with the traditional soft network closing, the advantages of strong impact resistance, high safety, high reliability and the like can be achieved.

Description

Technical field: [0001] The invention relates to a transmission line construction equipment, in particular to a spanning frame device used in transmission line spanning construction. Background technique: [0002] With the rapid development of transmission line construction in our country, the country pays more and more attention to the safety of construction. However, in the construction of existing transmission lines, crossing construction has the characteristics of many dangerous points and complex construction environment. At present, the method of setting up spanning frames is generally used to protect the objects to be spanned. Although the construction units design the lattice spanning frame to span the construction, although the basic functional requirements of spanning are met, there are some problems at the same time, such as large structural mass, complicated installation, structural Unstable and inconvenient for construction; hard-sealed net poles need to be inst...

Problems solved by technology

[0002] With the rapid development of my country's transmission line construction, the country is paying more and more attention to the safety of construction. In the construction of existing transmission lines, cross-stretching construction has the characteristics of many dangerous points and complex construction environment.

At present, the method of setting up spanning frames is generally used to protect the objects to be spanned. Although the construction units design the lattice spanning frame to span the construction, although the basic functional requirements of spanning are met, there are some problems at the same time, such as large structural mass, complicated installation, structural Unstable and inconvenient for construction; hard-sealed net poles need to be installed separately during installation, the construction time is long and the process is complicated; and it is prone to distortion during the implementation process, which not only increases the workload of construction personnel, but also is not safe enough; insufficient power And the power output process is not stable, prone to jamming
