The direction of the passage formed by the trestle, i.e., the left-right direction in fig. 1 and 4, is referred to as the longitudinal direction of the trestle in this embodiment.

In this embodiment, fig. 2 is a front view of the concrete paving trestle of this embodiment, the trestle body includes main beams located at the left and right sides and a cross beam connecting the main beams, and the lower portion of the main beam of the trestle body has a track extending outward. Wheels are arranged on the trolley assembly, the trolley assembly is hung on the rail through the wheels and is positioned below the trestle body, and the wheels on the trolley assembly can move along the rail. It should be noted that the above-mentioned manner illustrated in this embodiment is only one preferred manner, and does not limit the protection scope of the present invention, and other mounting and combining manners may also be adopted between the cart assembly and the trestle body, for example, the cart assembly is disposed between two main beams of the trestle body, and the cart assembly is suspended below the trestle body. The trolley component can adopt an active driving mode, for example, the trolley component comprises a driver, and the trolley component is driven to move on the trestle; the trolley assembly can also adopt a passive driving mode, for example, a driver is additionally arranged outside the trolley assembly, and the trolley assembly is pulled to move on the trestle body through transmission modes such as a chain and the like.

In this embodiment, the subassembly that paves is installed on the dolly subassembly, can be under the drive of dolly subassembly, along landing stage longitudinal movement to can pave the operation to the concrete of landing stage below. The paving assembly may select corresponding assemblies according to construction requirements, as shown in fig. 1, the paving assembly includes a spiral paving drum and a vibration leveling plate, the spiral paving drum is used for leveling the concrete to reduce the peak-valley difference of the concrete surface; the vibrating leveling plate is used for further compacting and leveling the surface of the concrete under the action of the vibrator, so that the effect of compacting and leveling the surface of the concrete is achieved; of course, other equipment, such as a flat vibrating device and the like, can be additionally arranged according to engineering requirements.
