The self-locking wheel 3 can realize the overall rapid movement of the assembled safety channel, with high moving efficiency, and the self-locking wheel 3 cooperates with the fixing device to ensure that the installation channel can be quickly locked and fixed after reaching the specified position, ensuring the stability and safety of use.

[0027] Specifically, the support unit 1 can be a support plate, and multiple support plates are assembled into a complete support frame in sequence. The length of the support frame is determined according to the cross-line needs on site, which is convenient for flexible construction and suitable for cross-line operations in different scenarios. The dual positioning of the self-locking wheel 3 and the fixing device ensures stability. Specifically, the locking device includes connecting ears 6 correspondingly arranged at the lower ends of the two adjacent support units 1, and a first bolt structure 7 is arranged between the two corresponding connecting ears 6. The support frame can be easily disassembled and installed through the bolt structure. In order to further improve the stability of the installation, the docking parts on both sides of the support unit 1 are respectively provided with slots and plug blocks 8 with corresponding positions and sizes. In the two adjacent support units 1, the plug block 8 of one support unit 1 is inserted into the slot at the corresponding position of the other support unit 1. During the actual installation process, the two adjacent support units 1 are docked so that the plug blocks 8 at the corresponding positions are stably inserted into the corresponding slots. At this time, the connecting ears 6 of the two adjacent support units 1 are aligned and directly fixed and locked by the first bolt structure 7.

[0028] Moreover, the detachable structure of the support frame and the ladder 2 can be a bolt-fixed structure, which can achieve rapid assembly and disassembly to form a modular assembly structure. Through simple connection and fixing devices, the installation and disassembly of the channel can be quickly completed, which greatly shortens the construction period. It is suitable for bridges with different central dividing strip widths and can be adjusted and installed according to actual needs, which improves the versatility and practicality of the channel.

[0029] The above-mentioned fixing device includes an adjustable clamp 9 movably arranged on the above-mentioned ladder 2, and a fixed adjustment component is arranged between the above-mentioned adjustable clamp 9 and the above-mentioned ladder 2.
