Abstract
The utility model discloses a quarrying box in a shield tunneling machine. The quarrying box comprises a box body, wherein the two ends of the box body are connected with a sludge pipe; a rotating shaft is arranged in the box body; and a plurality of pulling and shoveling rods are arranged on the rotating shaft. The rotating shaft is arranged in the box body of the traditional quarrying box and the pulling and shoveling rods are arranged on the rotating shaft, so sludge in the quarrying box is automatically stirred by driving the pulling and shoveling rods through the rotating shaft in an excavating process of the shield tunneling machine, dregs are smoothly discharged from a sludge discharging outlet of the quarrying box, a circulating pipe is ensured to smoothly circulate, and the excavating efficiency of the shield tunneling machine is effectively improved. The quarrying box is applied in the field of the shield tunneling machine.
Description
Technical field
The utility model relates to the quarrying case in a kind of shield machine.
Background technology
Shield machine is a kind of Work machine that is used for tunneling, and shield machine divides two big types of soil pressure and mud and water balances by working forms, and the muddy water system of slurry balance shield machine is divided into two major parts, muddy water induction system and muddy water treatment system.The muddy water induction system of slurry balance shield construction is a circulation system, and the quarrying case is exactly vitals in the circulation system.
In numerous construction methods of constructing tunnel, the construction method that the slurry shield construction method is nowadays tool modernization, technology content is the highest, compliance is the widest.Have high, the characteristics such as efficient is high, safety height of mechanization, automaticity.Slurry balance shield construction is meant in shield machine soil storehouse and is full of muddy water, and the soil pressure at face place and mud hydraulic pressure are confronted with each other, and lets constantly the circulate balance of maintenance excavation face of muddy water; Cut earth; See off with muddy water or mixed soil water or other fluid form, a quarrying of the pipeline front-end configuration case in that dregs is discharged enters into follow-up pipeline with stone or the walk that prevents bulk; Cause the spoil disposal pipeline blockage, and influence the efficient of shield machine driving.
When the slurry shield machine when mud advances; Traditional quarrying case can let mud be deposited in mud discharging mouth bit by bit, at this moment, has only through the P0 pump to form flowing of the acceleration mud that circulates in the machine; But the effect of this kind method is general; When mud is stacked into to a certain degree, can cause the obstruction of quarrying case mud discharging mouth or circulation pipeline, make headwork to carry out smoothly, only stop headwork this moment; Open and could continue driving after the quarrying case is cleaned out mud, frequent unlatching quarrying case will seriously influence the drivage efficiency and the working efficiency of shield machine.
The utility model content
For addressing the above problem, the utility model provides a kind of quarrying case that can in tunneling process, clear up voluntarily.
The utility model solves the technical scheme that its technical problem adopted:
Quarrying case in a kind of shield machine comprises the casing that two ends link to each other with the mud pipe, is provided with axis of rotation in the casing, and axis of rotation is provided with some groups of shovel rods.
Further as the improvement of the utility model technical scheme, casing is outside to be provided with the cycloidal-pin wheel reducer mutually with axis of rotation.
Further as the improvement of the utility model technical scheme; Axis of rotation is provided with three and dials the shovel rod; Each group shovel rod is installed on axial length points different on the axis of rotation; Be useful on the flange of dialling the shovel rod is installed dialling the fixed installation of shovel rod with every on the axis of rotation, flange is used for fixing the bolt that is connected with dialling to shovel to be provided with between rod.
Further as the improvement of the utility model technical scheme, dial the shovel rod and all install perpendicular to axis of rotation, each group shovel rod is not in same mounting plane.
The beneficial effect of the utility model: the quarrying case in this shield machine is through being provided with axis of rotation in the casing of traditional quarrying case; And it is excellent that some groups of shovels are set on axis of rotation; In the tunneling process of shield machine, driving group shovel rod through axis of rotation stirs the mud in the quarrying case voluntarily; Make dregs get rid of from the mud discharging mouth of quarrying case smoothly, smooth and easy with the circulation that ensures circulating line, effectively improve the drivage efficiency of shield machine.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the utility model embodiment overall structure sketch map;
Fig. 2 is the utility model embodiment overall structure side schematic view;
Fig. 3 is the revolute axes configuration sketch map of the utility model embodiment.
The specific embodiment
With reference to Fig. 1～Fig. 3, the utility model is the quarrying case in a kind of shield machine, comprises the casing 1 that two ends link to each other with the mud pipe, is provided with axis of rotation 2 in the casing 1, and axis of rotation 2 is provided with some groups of shovel rods 3.
Quarrying case in this shield machine is through being provided with axis of rotation 2 in the casing 1 of traditional quarrying case; And some groups of shovel rods 3 are set on axis of rotation 2; In the tunneling process of shield machine, driving the mud of dialling in 3 pairs of quarrying of shovel rod case through axis of rotation 2 stirs voluntarily; Make dregs get rid of from the mud discharging mouth of quarrying case smoothly, smooth and easy with the circulation that ensures circulating line, effectively improve the drivage efficiency of shield machine.
As the utility model preferred embodiment, casing 1 outside is provided with cycloidal-pin wheel reducer 4 mutually with axis of rotation 2.
Space in the quarrying box body 1 is smaller; So the rotating speed of axis of rotation 2 is unsuitable too fast; And characteristics such as the moment of torsion that needs axis of rotation 2 is bigger are used cycloidal-pin wheel reducer 4 comparatively widely so in the utility model, adopt in the industry, to realize deceleration and to increase its torsional moment simultaneously.
As the utility model preferred embodiment; Axis of rotation 2 is provided with three and dials shovel rod 3; Each group shovel rod 3 is installed on axial length points different on the axis of rotation 2; Be useful on the flange 5 of dialling shovel rod 3 be installed dialling 3 fixed installations of shovel rod on the axis of rotation 2 with every, flange 5 with dial excellent 3 of shovel and be provided with and be used for fixing the bolt 6 that is connected.
As the utility model preferred embodiment, dial shovel rod 3 and all install perpendicular to axis of rotation 2, each group shovel rod 3 is not in same mounting plane.
The different length place that in the casing 1 of this quarrying case each group shovel rod 3 is arranged on the axis of rotation 2, and become different angles that each group shovel rod 3 is provided with, to strengthen its stirring in quarrying box body 1 to mud.
Certainly; The invention is not limited to above-mentioned embodiment; Those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
