Furthermore, the crawling ladder is fixedly connected with the suspension structure through welding, and the crawling ladder and the construction platform are connected with the screw through a connecting rod; the ladder stand and the construction platform are provided with ladder lattices therebetween.

Furthermore, the clamping jaws are of a right-angle structure formed by welding two long steel pipes.

Furthermore, the clamping jaw and the hanging support are of an integrated structure.

Furthermore, the bottom of the construction platform is provided with a panel for workers to stand, two sides of the construction platform are provided with protection rods which are obliquely arranged, the protection rods are connected to one side, back to the outer wall of the bridge, of the stand column of the ladder stand, and a trapezoidal cavity for the workers to stand for construction is formed between the protection rods and the ladder stand.

Compared with the prior art, the utility model has the beneficial effects that: 1. the dismounting is convenient, the device is divided into three parts, one end of the device is arranged to be a suspension structure of a fixed end, the other end of the device is an operation personnel construction platform, and the middle of the device is a ladder stand structure additionally provided with a transverse steel pipe. The cat ladder and suspended structure and construction platform by simple and easy steel pipe group, it is little to occupy the bridge floor space, does not influence the normal traffic of bridge floor. And the weight is light, the cost is low, and the device can be installed and constructed on site by one person without the investment of a large amount of manpower and material resources.

2. The setting space is simple, and the cat ladder is provided with the support component towards one side of bridge outer wall, makes to form simple and easy construction space between cat ladder and the bridge outer wall, makes things convenient for the workman to fall the foot from top to bottom. The right-angle type jack catch that suspended structure set up can be with turning over the firm joint of ladder on the guardrail, improve and turn over the ladder bearing, keep turning over the ladder balance. The safety belt and the safety rope are matched for construction, so that safe and efficient construction of constructors can be guaranteed.
