Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for lining trolleys, and specifically to a pipe delivery mechanism for concrete conveying pipes of lining trolleys. Background Technology

[0002] Tunnel lining trolleys are construction equipment used for tunnel lining. Currently, the grouting method using lining trolleys is undergoing an upgrade from manual to automated grouting. One method involves using an automated multi-degree-of-freedom (DOF) grouting robot. During grouting, the robot moves linearly back and forth along the length of the trolley, and the movement of the joints of the multi-degree-of-freedom robot moves the concrete pipe at the end of the robot to the various positions on the trolley that need grouting. However, the concrete delivery pipe of the trolley is generally made of steel. When the multi-degree-of-freedom robot moves linearly back and forth along the length of the trolley, the ordinary steel concrete delivery pipe cannot extend or retract with the robot, resulting in a significant reduction in grouting efficiency.

[0003] Therefore, designing a cleverly conceived, convenient concrete delivery mechanism for the lining trolley, which allows the concrete delivery pipe of the lining trolley to extend and retract with the back-and-forth movement of the grouting robot, thereby improving the automation of the concrete delivery process of the tunnel lining trolley and increasing the lining efficiency of the trolley, has become a problem that must be solved for current tunnel lining trolley products. Utility Model Content

[0004] To address the technical problem that ordinary steel concrete conveying pipes cannot extend and retract with the back-and-forth movement of the robotic arm during the concrete placement process of tunnel lining trolleys, resulting in a significant reduction in placement efficiency, this utility model provides a pipe delivery mechanism for the concrete conveying pipe of the lining trolley. This ingenious design facilitates concrete placement, and the concrete conveying pipe of the lining trolley can extend and retract with the back-and-forth movement of the grouting robotic arm, thereby improving the automation of the concrete placement process of the tunnel lining trolley and increasing the lining efficiency of the trolley.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a pipe delivery mechanism for a lining trolley concrete delivery pipe, including a track, a sliding trolley, a support frame, an intermediate bearing, a delivery pipe support rod assembly and a pipeline system. The track is fixed on the lining trolley gantry to support and guide the entire concrete delivery pipe delivery mechanism.

[0007] As a further optimization of the above-mentioned concrete conveying pipe delivery mechanism for the lining trolley, the support frame includes a support beam and a support column. The support column is fixed in the middle of the support beam, the lower part of the support beam is connected to the sliding trolley, and the upper end of the support column is connected to the conveying pipe support rod assembly through an intermediate bearing. The connection between the support column and the conveying pipe support rod assembly can rotate horizontally.

[0008] As a further optimization of the pipe delivery mechanism of the concrete conveying pipe of the lining trolley mentioned above, the conveying pipe support rod assembly includes a front connecting rod, a middle connecting rod, a rear connecting rod, a hollow hinge shaft, and a fixed seat. The front connecting rod, the middle connecting rod, and the rear connecting rod are connected by the hollow hinge shaft, and adjacent connecting rods can rotate relative to each other. The middle connecting rod is provided with a bearing mounting hole in the middle to assemble the middle connecting rod with the support column and the intermediate bearing, so that the middle connecting rod has the freedom of horizontal rotation. The rear end of the fixed seat is welded and fixed to the trolley gantry. The fixed seat and the rear connecting rod are connected by the hollow hinge shaft, and the connection point can rotate relative to each other.

[0009] As a further optimization of the pipe delivery mechanism of the concrete conveying pipe of the lining trolley mentioned above, the number of the central connecting rods is three to eight.

[0010] As a further optimization of the above-mentioned concrete conveying pipe of the lining trolley, the pipeline system includes a connecting straight pipe, a bend, an upper straight pipe, a lower straight pipe, a conveying pipe support, pipe clamps, and a sealing ring. The connecting straight pipe, bend, upper straight pipe, and lower straight pipe are connected by pipe clamps, and the connection joints are sealed by sealing rings. The conveying pipe support is set between the upper straight pipe and the lower straight pipe to fix the entire pipeline system on the conveying pipe support rod assembly.

The middle connecting rod 502 has a bearing mounting hole in its middle part to assemble the middle connecting rod 502 with the support column 302 and the intermediate bearing 4, so that the middle connecting rod 502 has the freedom of horizontal rotation. The number of middle connecting rods 502 is three to eight. The rear end of the fixed seat 505 is welded and fixed to the trolley gantry.
