Description

Technical Field

[0001] This utility model relates to the field of construction, and more particularly to rail transit construction equipment technology, specifically a track slab and self-compacting concrete leveling and pouring device. Background Technology

[0002] In modern rail transit engineering, self-compacting concrete (SCC) is an ideal material for track slab construction due to its properties such as requiring no vibration and high fluidity. During track construction, SCC is poured between the track slab and the base slab to form a composite slab structure. However, existing SCC pouring processes are highly dependent on manual intervention. It requires manual observation of the concrete flow state, and when the flow pressure of the SCC causes track slab displacement, the concrete placing boom's discharge speed needs to be manually adjusted. Furthermore, manual correction and leveling are required afterward, making the operation quite cumbersome. Utility Model Content

[0003] The purpose of this utility model is to provide a track slab and self-compacting concrete leveling and pouring device. The track slab and self-compacting concrete leveling and pouring device is to solve the technical problem in the prior art that when the flow pressure of self-compacting concrete causes the track slab to shift, it is necessary to manually adjust the discharge speed of the concrete placing machine and then manually correct and level it afterward.

[0004] This utility model discloses a track slab and self-compacting concrete leveling and pouring device, including a mounting frame. A traveling mechanism is provided at the bottom of the mounting frame, and a concrete placing machine is provided on the mounting frame.

The telescopic rod driving devices are spaced apart along the length of the mounting frame and distributed on the left and right sides of the mounting frame. The power output end of the telescopic rod driving device is connected to a pressure rod, and the movement direction of the pressure rod is parallel to the vertical direction. The signal output ends of the first and second detection sensors, the electric regulating valve, the screw conveying mechanism, and the control end of the telescopic rod driving devices are all connected to a controller.
