Description
Technical Field
The invention relates to the technical field of slag soil emission in a TBM tunneling process, in particular to a slag soil collecting and vertical lifting device for a tunnel.
Background
With the large-area popularization and application of underground construction, most underground tunnels are deslagged by adopting a belt conveyor, so that the construction efficiency is improved to a great extent, the construction cost is saved, and a good application effect is achieved. However, when the vertical inclined shaft is encountered, the belt conveyor slag tapping cannot be implemented, an additional slag tapping mode is required to be arranged, the construction period is prolonged in an intangible way, and the construction cost of engineering is increased.
At present, in the TBM construction process, in order to achieve the purpose of saving cost, a hole is frequently constructed in two directions simultaneously, so that one hole can be fully utilized. However, the combined discharge of the dregs becomes a difficult problem in this case, and most of the prior art is behind. For example, two supporting hole belt conveyors are adopted for transportation in some projects, so that the space of supporting holes is occupied, and the construction cost is increased; in addition, some locomotives used in engineering are transported, and too high time and economic waste exist, so that the expected result of engineering construction is far less than that of engineering construction.

The functions of collecting and lifting the multi-directional tunnel slag soil outside the tunnel are efficiently completed through the effective combination of the slag soil collecting rotary table, the rotary table motor, the support, the crawler, the idler wheels, the crawler motor and the bucket, so that the cost is saved for the discharge of TBM slag soil, the space in the tunnel is saved, and necessary guarantee is provided for the on-schedule completion of engineering.
The concrete technical scheme of the slag soil collecting and vertical lifting device for the tunnel comprises a supporting part, a slag soil collecting part positioned above the supporting part and a lifting part positioned above the slag soil collecting part, wherein the supporting part is provided with a lifting part; the lifting part comprises a crawler belt which is vertically arranged, idler wheels which are arranged in the crawler belt, and a plurality of buckets which are arranged in the same direction and are used for lifting dregs and are fixed on the crawler belt; the dregs collecting part is a rotary turntable arranged above the supporting part.
Further, the lifting part is arranged on the wall of the tunnel through the connecting bracket.
Further, the lower end of the crawler belt is positioned above the outer edge of the upper surface of the rotary table, and the distance from the lower end head of the crawler belt to the upper surface of the rotary table is slightly larger than the vertical height of the bucket.
Further, at least one driving roller and at least one driven roller are arranged in the crawler belt, and the driving roller is connected with a crawler belt motor.
Further, a turntable motor for driving the turntable to rotate is arranged below the turntable.
Further, the turntable is of a basin-shaped structure, the radius of the turntable is 06-1.6 meters, and the depth of the turntable is 0.4-4 meters.
More specifically, the support portion adopts the support, and size, height and the bearing capacity of support are adjusted according to the model of carousel to be suitable for different engineering, the support structure can nimble adjustment, according to tunnel size, tunnel play sediment volume, the quantity of awaiting excavation tunnel, excavation tunnel dregs nature difference, can carry out the regulation of different scope.
According to the invention, the rotating turntable is arranged at the top of the bracket, the size of the turntable is determined according to the actual condition of a project site, the turntable can rotate at different speeds along one direction, and dregs conveyed from any angle can be conveyed to the upper part of the turntable and collected on the outer diameter of the turntable. The dregs rotate along with the rotation of the turntable, and when the dregs rotate to the position of the point of the bucket, the dregs are shoveled out by the bucket. The advantage of doing so is that can receive 360 degrees different angle tunnel muck to can receive muck that the transportation of many tunnels comes, form the collection of muck, and because the rotation of carousel, can clean up the muck on the carousel.
The invention determines the length of the crawler belt according to the length of the branch hole, and configures a certain number of buckets according to the requirement.
The tracks with buckets in the invention run vertically. The rotating direction of the turntable is based on the rotating direction of the slag soil to be transported in the turntable when the bucket digs soil, the slag soil is shoveled out by the power of the crawler belt and the self weight of the bucket, and the slag soil is lifted out of the hole to form circulation. The number of buckets is determined by the length of the vertical shaft and the slag rate of the slag.
According to the invention, a certain number of rollers can be added according to the length of the crawler belt, the rollers are connected to two ends of the crawler belt to drive the crawler belt to rotate, and when the length is required, the configuration of the rollers is increased to ensure the running of the crawler belt. The rollers are connected to the vertical shaft through the configuration of the forehead connecting device so as to adapt to vertical support holes with different lengths.
The invention has the beneficial effects that: according to the invention, the functions of collecting and lifting the multi-directional tunnel slag soil outside the tunnel are efficiently completed by effectively combining the slag soil collecting turntable, the turntable motor, the bracket, the crawler, the idler wheels, the crawler motor and the bucket, so that the cost is saved for discharging the TBM slag soil, the space in the tunnel is saved, and the necessary guarantee is provided for the on-schedule completion of engineering. Has good application prospect.
