Embodiment 1

[0035] A pole-holding cross frame on both sides of an expressway, comprising a ground anchor mechanism for enhancing stability, a support mechanism arranged on the ground anchor mechanism, and a span mechanism arranged on the support mechanism, the ground anchor The mechanism, the supporting mechanism and the spanning mechanism are all connected to the control mechanism;

[0036] The ground anchor mechanism includes a ground anchor plate 19 composed of a plurality of ground anchor units, a counterweight unit 23 arranged on the ground anchor plate 19, a load-bearing ring 18 arranged on the peripheral side of the ground anchor plate 19, and a load-bearing ring connected to the ground anchor plate 19. 18 connected pulling ropes 1;

[0037] The support mechanism includes a fixed base 15, a telescopic rod 2 arranged on the fixed base 15, and a fixed base 3 arranged on the telescopic rod 2, and the telescopic rod 2 is arranged on the telescopic rod 2 to connect with the pull rope 1 ...

Embodiment 2

[0054] The difference from Embodiment 1 is that: the main telescopic arm 6 is provided with a support groove 11 that matches the first telescopic arm 8 .

[0055] The first fixed pulley 26 matched with the fixed pulley is arranged at the top of the telescopic rod.

[0056] In this embodiment, a support groove is added to support the first support arm, so as to ensure that the first telescopic arm can be strongly supported when it is deployed, ensuring the stability of the structure, and the fixed pulley and the first fixed pulley are set Conveyor rope for item conveyance.

Embodiment 3

[0058] The difference from the second embodiment is that the first telescopic arm 8 has a honeycomb structure 82 inside and a chrome-plated layer 81 on its surface.

[0059] The honeycomb structure is arranged inside the first telescopic arm adopted in this embodiment, which can reduce the structural weight without changing the structural strength.

Abstract

The invention discloses a pole-holding spanning frame on both sides of an expressway, comprising a ground anchor mechanism for enhancing stability, a support mechanism arranged on the ground anchor mechanism, and a span mechanism arranged on the support mechanism, The ground anchor mechanism, the support mechanism and the spanning mechanism are all connected to the control mechanism; the front end of each sub-telescopic arm of the first telescopic rod is provided with an attitude adjustment module, and the sub-telescopic arm close to the attitude adjustment module An emergency buoyancy module is installed on the arm, and a balance adjustment module is installed on the first telescopic arm to adjust the posture according to the balance monitoring module at the front end when the tilt occurs or the weight is large and the wind force is small, so as to ensure that the accidental fall occurs. In practice, the stability of the device is guaranteed through the emergency buoyancy module and the attitude adjustment module.

Description

technical field [0001] The invention belongs to the technical field of auxiliary equipment for electric power construction, and in particular relates to a pole-holding grid spanning frame on both sides of an expressway. Background technique [0002] Since the quality of the transmission wire, especially the high-voltage transmission wire itself, is large, and the two adjacent iron towers used to support the transmission wire have a large span, and there are charged objects, crops, trees, etc. between the two adjacent iron towers. Obstacles such as rivers, roads, buildings and structures are crossed, so erecting or dismantling transmission lines is a complex and difficult project. [0003] In the prior art, erecting or dismantling the transmission wire usually adopts a guide rope installed between two adjacent iron towers and a pulley suspended on the guide rope and controlled by the pull wire, and in order to avoid the transmission wire from contacting the ground or the abov...
