Embodiment 1

[0027] In order to overcome the problems existing in the prior art, it provides a safe and efficient erection method for pulling a leading cable across a river without interruption of traffic, free from terrain and hydrological restrictions, short operation time, low risk, and safety.

[0028] This embodiment provides a figure 1 The shown construction method of unmanned aerial vehicle towing the pilot cable across the river includes the following steps:

[0029] 1) On the top of the tower at one end of the bridge at the starting point 5, place the pilot cable reel 4 and the UAV 1;

[0030] 2) Pull out the pilot cable 2 from the cable reel 4 to connect with the UAV 1, and at the same time bind the counterweight 3 to the pilot cable 2;

[0031] 3) The UAV 1 pulls the pilot cable 2 and flies to the top of the bridge at the other end of the terminal 6;

[0032] 4) The operator pulls and catches the pilot cable 2 on the top of the tower, the UAV 1 releases the connection with the...

Embodiment 2

[0035] This embodiment provides a figure 1 The shown construction method of unmanned aerial vehicle towing the pilot cable across the river includes the following steps:

[0036] 1) On the top of the tower at one end of the bridge at the starting point 5, place the pilot cable reel 4 and the UAV 1;

[0037] 2) Pull out the pilot cable 2 from the cable reel 4 to connect with the UAV 1, and at the same time bind the counterweight 3 to the pilot cable 2;

[0038] 3) The UAV 1 pulls the pilot cable 2 and flies to the top of the bridge at the other end of the terminal 6;

[0039] 4) The operator pulls and catches the pilot cable 2 on the top of the tower, the UAV 1 releases the connection with the pilot cable 2, and manually anchors the pilot cable 2 to the anchor point 7 on the tower top.

[0040] Among them, as a preferred embodiment, in the step 1) and step 3), one end of the bridge as the starting point (5) and the ending point (6) includes the tower top and the ground. The ...

Embodiment 3

[0042] This embodiment provides a figure 1 The shown construction method of unmanned aerial vehicle towing the pilot cable across the river includes the following steps:

[0043] 1) On the top of the tower at one end of the bridge at the starting point 5, place the pilot cable reel 4 and the UAV 1;

[0044] 2) Pull out the pilot cable 2 from the cable reel 4 to connect with the UAV 1, and at the same time bind the counterweight 3 to the pilot cable 2;

[0045] 3) The UAV 1 pulls the pilot cable 2 and flies to the top of the bridge at the other end of the terminal 6;

[0046] 4) The operator pulls and catches the pilot cable 2 on the top of the tower, the UAV 1 releases the connection with the pilot cable 2, and manually anchors the pilot cable 2 to the anchor point 7 on the tower top.

[0047] Wherein, as a preferred embodiment, the UAV 1 is a remote-controlled aircraft equipped with an inertial navigation system. The remote-controlled aircraft is a four-rotor aircraft or a...

Abstract

The invention provides a construction method for pulling a pilot cable across a river by an unmanned aerial vehicle, which comprises the following steps: placing a pilot cable reel and an unmanned aerial vehicle on the tower top of one end of the bridge at the starting point; The drone is connected, and at the same time binds the counterweight on the pilot cable; the drone pulls the pilot cable and flies to the top of the bridge at the other end of the terminal; the operator pulls and catches the pilot cable on the top of the tower, and the drone releases the pilot Cable connection, the pilot cable is manually anchored at the anchor point on the top of the tower. This invention designs and develops a complete dynamic flight mode, with short construction period and low cost, and realizes unsealed airways (roads) in the true sense, avoiding terrain, hydrology, and traffic restrictions, and reducing construction risks, which is easy to promote application.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a construction method for crossing a river by a pilot cable pulled by an unmanned aerial vehicle. Background technique [0002] When erecting the traction system of a suspension bridge, when it is difficult to directly erect the traction cable of the traction system, it is first necessary to erect a pilot cable thinner and lighter than the traction cable, and then use the pilot cable to form the traction system. [0003] In mountainous bridges with high mountains and steep slopes, rich vegetation, rapid water flow, bridges with deep rivers and seas, complex hydrology, and many navigable ships, and bridges crossing roads and lines, the pilot cable construction adopts the conventional artificial ground pulling method or aerial traction. The method (rocket throwing rope method, helicopter, remote-controlled airship), high cost, difficult construction, long time for air closure and r...
