Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a disc-type automatic material distribution device used on a secondary lining trolley. Background Art

[0002] The existing tunnel secondary lining concrete pouring is usually carried out using a lining trolley. The existing lining trolley includes a car body with an arched formwork sleeved on the outside of the car body. When pouring concrete, the outlet of a feed pipe is directly aligned with the area on the arched formwork for concrete pouring.

[0003] However, in the process of concrete delivery and distribution, two delivery methods are usually adopted. One is a single delivery pipeline, and manual distribution is performed manually, which is not only time-consuming and labor-intensive, but also uneven in distribution. The other is a disc distribution method that uses multiple pipelines for distribution. However, when switching the delivery pipelines, manual operation is still required to achieve the connection between the pipelines and the delivery pipelines, which makes the efficiency low. Therefore, the utility model provides a disc-type automatic distribution device for the secondary lining trolley to meet the needs. Utility Model Content

The external water supply equipment is turned on, and the cleaning water is sprayed out through the cleaning nozzle 5.2 to flush the grouting channel 2. The rotary hydraulic motor 3.1 can be started as needed to drive the rotating platform 3.4 and the covering plate 3.3 to rotate, so that the cleaning nozzle 5.2 is aimed at each grouting channel 2 in turn for cleaning. The waste and sewage generated during the process fall into the interior of the rotating platform 3.4 through the waste collection hole under the action of the flushing force. The waste and sewage accumulate inside the rotating platform 3.4 and are then scraped off by the cleaning plate on the inner wall of the fixed seat 1. The cleaning plate is located above the rotation path of the waste collection hole to ensure that the waste and sewage can fall into the waste collection hole smoothly and be collected and processed in a unified manner. When all grouting channels 2 are cleaned, the external water supply equipment is turned off, and the No. 2 hydraulic telescopic rod 5.1 is started to retract it, and the cleaning nozzle 5.2 is retracted into the covering plate 3.3 to prepare for the next use.
