Description
Technical Field
The utility model relates to a technical field that dregs were carried especially points out sediment system leak protection device.
Background
In the current tunnel construction adopting the earth pressure shield method, a spiral conveyor is basically adopted to discharge the muck excavated by a cutter head to a rear matched belt conveyor, and then the muck is conveyed to the ground through a marshalling train or a tunnel belt conveyor.
The back supporting belt conveyor can have more slag falling or slurry overflowing phenomena when receiving the slag discharged by the spiral conveyor and the tunnel belt conveyor, so that a large amount of accumulated slag is always generated on the pipe pieces to be spliced and the tunnel ground placed below the back supporting belt conveyor, and the accumulated slag on the pipe pieces and the tunnel ground is required to be continuously cleaned and washed. If the fallen muck is cleaned in the tunneling process, the fallen muck can splash and fall onto the body of a constructor, so that the tunnel construction environment is influenced, and potential safety hazards also exist. Therefore, a leakage-proof device of a slag discharging system is urgently needed to be designed, so that the problem of pollution of slag discharging and water leakage of the slag discharging system to the tunnel environment is solved, the workload of construction workers is reduced, and the equipment operation is more humanized.
Through the retrieval, the utility model patent that current grant bulletin date is 20190830, grant bulletin number is CN209324368U discloses a device that dregs were collected and got rid of when being used for the spiral gush in the shield construction, utilizes to connect the sediment groove to realize that the dregs are concentrated to transport the dregs to the sediment fill through connecing the sediment groove, recycle hydraulic pressure dregs pump and arrange the dregs to the belt feeder, manual work when replacing screw conveyer gush clears up the dregs.
Although the technical scheme of above-mentioned patent can play the collection sediment effect of certain degree when the spiral belt feeder gushes, can not solve back supporting belt feeder and caused the sediment phenomenon of leaking when normally receiving the sediment that comes from the screw conveyer emission and tunnel belt feeder when normally receiving the sediment that comes from back supporting belt feeder emission. As shown in the embodiment and the attached drawings of the specification, the slag collecting device of the technical scheme of the patent needs the slag receiving groove to be matched with the slag collecting hopper for use together, and in order to meet the working condition of wide spraying range during the gushing of the spiral conveyor, the slag receiving groove has to have enough length and is movably hinged on a wheel carrier of the belt conveyor. When screw conveyer gushes, will connect the sediment groove to put down through the section of jurisdiction loop wheel machine, when screw conveyer does not gush, will connect the sediment groove to hoist through the section of jurisdiction loop wheel machine to the section of jurisdiction is normally carried to the wheel carrier below of belt feeder, consequently the technical scheme of this patent can not continuously collect and leak the sediment, can't solve slag discharging system and fall the sediment, leak the pollution to tunnel environment, can't reduce construction worker's work load.
