Abstract

The invention belongs to the technical field of the conveying of concrete during tunnel lining and relates to a terminal mechanism for a concrete distributor and a multi-degree-of-freedom concrete distribution system. The terminal mechanism is connected to a discharging pipe of the concrete distributor and comprises a movable pipe, wherein the movable pipe is communicated with the discharging pipeand is supported at the end part of the discharging pipe through a gyration assembly; a distribution flexible pipe is communicated with the movable pipe, and a swinging assembly is arranged between the movable pipe and the distribution flexible pipe; and the gyration assembly is used for driving the movable pipe and the distribution flexible pipe to execute an gyration action, and the swinging assembly is used for driving the distribution flexible pipe to execute an floatation swinging action relative to the movable pipe. According to the terminal mechanism, the multi-degree-of-freedom adjustment of concrete can be realized on a hemisphere surface, so that the practicability of the concrete distributor is greatly improved, the terminal mechanism can meet the concrete conveying requirementduring the secondary lining of a tunnel, the movement of the whole equipment and the adjustment of the concrete conveying direction are reduced, and the working efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of concrete conveying in tunnel lining, and in particular relates to a terminal mechanism of a concrete distributing machine and a multi-degree-of-freedom concrete distributing system. Background technique [0002] At present, in the concrete construction of the construction site, the concrete placing machine is used for construction. The function of the concrete placing machine is to send the pumped concrete to the pouring position through the pipeline. Generally, a hose is connected to the end of the concrete placing machine, and the hose hangs down, and the concrete falls to the pouring position through the hose. In the construction of the secondary lining concrete of the tunnel, it is required that the pipeline terminal can realize the horizontal or upward conveying of the concrete. The conventional method cannot realize the horizontal or upward conveying of concrete, and cannot realize the adjustment ...
