Problems solved by technology

[0002] The catwalk is a cross-river construction platform temporarily built during the erection of the main cable of the suspension bridge. Its direction is consistent with that of the main cable of the suspension bridge. Traditional catwalk construction generally adopts manual laying of catwalk boards, which is not only time-consuming and laborious, but also has great safety hazards in high-altitude operations

Embodiment 1

[0039] Such as figure 1 Shown, a kind of suspension bridge catwalk laying construction system comprises catwalk board 10 and laying device 20; As Figure 1-14 As shown, the catwalk board 10 includes a plate-shaped body, the bottom of the plate-shaped body is provided with a first clamping mechanism 11 for preventing the radial displacement of the plate-shaped body along the catwalk load-bearing cable 1, and for preventing the board The second clamping mechanism 12 for axially displacing the catwalk load-bearing cable 1 along the catwalk load-bearing cable 1; And the first clamping mechanism 11 and the second clamping mechanism 12 can be driven to clamp the catwalk load-bearing cable 1 when the downward pressure is applied to the plate-shaped body; Figure 15-21As shown, the laying device 20 includes a material storage rack 21 for stacking catwalk boards 10, and the bottom and both sides of the storage rack 21 are respectively provided with a rolling joint with the catwalk loa...

Embodiment 2

[0050] A kind of suspension bridge catwalk laying construction method, comprises the steps:

[0051] Step 1: Set up catwalk load-bearing cables 1, catwalk guardrail cables 2 and catwalk traction cables 3, of which catwalk load-bearing cables 1 are 6-8 and are located in the same plane, and catwalk guardrail cables 2 are two in the most Above the two catwalk load-bearing cables 1 on the outside, two catwalk traction cables 3 are respectively located above the two catwalk load-bearing cables 1 in the middle, and the catwalk traction cables 3 are connected to the hoist;

[0052] Step 2: Install the catwalk board 10 laying device 20 on the catwalk load-bearing cable 1 and the catwalk guardrail cable 2, and connect the catwalk board 10 laying device 20 with one of the catwalk traction ropes 3 with a rope and a traction frame 4 ;

[0053] Step 3: Stack the catwalk board 10 in the catwalk board 10 laying device 20, use the catwalk traction rope 3 to place the catwalk board 10 laying...

Embodiment 3

[0061] A method for dismantling catwalk boards, pressurizing the locking plate 114 in the catwalk board 10 from both sides of the catwalk board 10, so that the locking groove 1141 on the locking board 114 is facing the locking pin 115, locking Under the action of the second elastic unit 1152, the pin 115 pushes the locking pin 115 into the locking groove 1141 to lock the first clamping block 112 in the open state, and then the catwalk board 10 is lifted upwards, so that the first clamping mechanism 11 separates with catwalk load-bearing cable 1.

[0062] The removal method also includes: applying pressure to the driving frame 13 in the catwalk board 10 along the length direction of the catwalk load-bearing cable 1, so that the second clamping block 122 moves to the end where the two guide surfaces are far away from each other, and the second clamping block 122 moves the catwalk The load-bearing cable 1 is loosened, and then the locking plate 114 in the catwalk plate 10 is pres...

Abstract

The invention belongs to the technical field of bridge construction, and particularly relates to a catwalk plate for suspension bridge construction. The catwalk plate comprises a plate-shaped body, wherein the bottom of the plate-shaped body is provided with a first clamping mechanism for preventing the plate-shaped body from moving along the radial direction of a catwalk bearing cable, and a second clamping mechanism for preventing the plate-shaped body from moving along the axial direction of the catwalk bearing cable; a linkage triggering mechanism is further arranged in the plate-shaped body, and the linkage triggering mechanism is assembled to be capable of driving the first clamping mechanism and the second clamping mechanism to clamp the catwalk bearing cable when the plate-shaped body is placed on the catwalk bearing cable and exerts downward pressure on the plate-shaped body. The catwalk plate is provided with the first clamping mechanism and the second clamping mechanism which can automatically clamp the catwalk bearing cable. After the catwalk plate is laid on the catwalk bearing cable, downward pressure is applied to the catwalk plate, so that the first clamping mechanism and the second clamping mechanism can clamp the catwalk bearing cable, axial and radial fixation of the catwalk plate and the catwalk bearing cable is achieved, and automatic laying of the catwalkplate is facilitated.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a catwalk board used for suspension bridge construction. Background technique [0002] The catwalk is a cross-river construction platform temporarily built during the erection of the main cable of the suspension bridge. Its direction is consistent with that of the main cable of the suspension bridge. Traditional catwalk construction generally adopts manual laying of catwalk boards, which is not only time-consuming and laborious, but also poses great safety hazards when working at heights. Contents of the invention [0003] The purpose of the present invention is to provide a catwalk board for suspension bridge construction, which can realize the automatic clamping of the face and the lock body, so as to facilitate the automatic paving of the catwalk board. [0004] The technical scheme that the present invention takes is specifically as follows: [000...
