Trailer system for circularly conveying and dumping muck of shield tunneling machine

Abstract

The invention relates to a shield tunneling machine residue soil circulation conveying and dumping trailer system which comprises a trailer chassis, a carriage and a lifting and dumping mechanism. Three connecting columns are arranged at the two ends of the carriage, two connecting columns are symmetrically arranged relative to the vertical center face of the carriage and close to the upper opening of the carriage, and the third connecting column is arranged on the lower portion of the carriage. The lifting and dumping mechanism comprises a rack, a transmission chain and a chain wheel, the transmission chain and the chain wheel are arranged on the rack and matched with each other, the chain wheel is connected with a driving device, hooks are arranged at the two ends of the transmission chain, one hook is used for being connected with one connecting column on the upper portion, and the second hook is used for being connected with a hanging ring at the end of the connecting arm. The length of the transmission chain is L, the distance between the two upper connecting columns is l, the perimeter of the chain wheel is C, and L is larger than 2l + C / 2. The lifting dumping mechanism can turn over the carriage by more than 150 degrees, and if the turning degree reaches 180 degrees, the muck in the carriage can be completely dumped out, and no muck is left.

Description

technical field [0001] The invention belongs to the field of shield tunneling construction, and in particular relates to a dumping trailer system for circularly conveying dregs of a shield tunneling machine. Background technique [0002] The shield machine is a tunnel boring machine that uses the shield method, and the construction method of the shield tunnel is that the tunnel boring machine constructs the supporting pipe of the tunnel while driving. During the construction process, the front shield excavates and cuts the soil, and the cut soil is conveyed to the rear through the muck conveyor belt. [0003] Due to the different construction environments, the properties of the soil to be cut are also different. For the soil with a large water content in the construction of the earth pressure shield machine, it is difficult to directly discharge the muck from the underground to the ground by laying pipelines. The soil cut by the shield head is transferred along the tunnel t...

AI Technical Summary

Problems solved by technology

The trailer moves at a constant speed in the tunnel. There are more manual interventions in lifting, dumping, and putting back, so it will take up more time. After the dumping time is prolonged, the overall transportation efficiency of the muck will be delayed. If the time If it is too long, the shield machine needs to stop working to wait for the muck truck to be in place, which will affect the excavation work and delay the progress of the entire project
