Problems solved by technology

[0002]With the rapid development of transmission line construction, users are paying more and more attention to the safety of construction, and in the construction of existing transmission lines, there are dangerous points in the construction of straddling lines Many, complex construction environment and other characteristics
[0003]Currently, spanning frames are commonly used to protect the objects to be spanned. Although each construction unit meets the basic functional requirements of spanning when designing lattice spanning frames, the At the same time, there are some problems, such as large structural mass, complicated installation, unstable structure, and inconvenient construction; the hard-sealed net poles need to be installed separately during installation, which takes a long time and is complicated in the process; and it is prone to distortion during the implementation process, not only Increase the workload of construction personnel, and at the same time, it is not safe enough; the power is insufficient and the power output process is not stable, and it is prone to jamming

Embodiment Construction

[0024] In order to better understand the present invention, the content of the present invention will be further described below in conjunction with the accompanying drawings and examples.

[0025] Such as figure 1 As shown, it is a schematic diagram of the initial installation of the folding and rotating spanning frame provided by the present invention. After adjusting different spanning heights through the lifting platform 2, the power device is used to drive the power rope 3 through the steering pulley 1 to realize the folding strut 5 moving up and down along the slide rail 4. After the folding arm 8 is opened, the rotation of the rotating platform 6 quickly realizes folding on both sides Arm 8 seals the net butt.

[0026] Such as figure 2 As mentioned above, it is a schematic diagram of the lapped and rotated spanning frame provided by the present invention. The spanning frame includes a rotating mechanism, a lifting mechanism and an executing mechanism arranged on the...

Abstract

The invention discloses a folding rotary crossing over frame, which comprises a supporting mechanism, and a lifting mechanism and an actuator vertically disposed on the supporting mechanism, wherein the lifting mechanism comprises a lifting platform disposed on the supporting mechanism, a sliding rail fixed on the lifting platform in a vertical direction and upper and lower sliders arranged at oneside of the sliding rail; the lower slider is controlled by a steering pulley arranged at the other side of the supporting mechanism through a power rope; and the actuator comprises a folding arm connected with the upper slider, a folding strut connected with the lower slider, multiple network closing holding bars fixed in rail clamping grooves above the folding arm and a connecting pin shaft arranged at the other side of the folding arm. The structure is simple, and the engineering cost is reduced; the construction is convenient; the network closing speed is quick, a network closing assemblyfunction can be easily realized through a rotating mechanism, and an unsmooth docking situation does not happen easily.

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, users are 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. [0003] At present, the method of erecting spanning frames is generally used to protect the objects to be spanned. Although the construction units design the lattice type 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, and poor structure. It is stable and inconvenient for construction; the hard-sealed net holding ...
