Description
Technical Field
The utility model relates to an auxiliary stirring device mounted on a main drive of a shield machine, and belongs to the technical field of shield machines.
Background
At present, urban rail transit construction in China steps into a rapid development stage, the shield method plays an increasingly important role in urban subway tunnel construction due to various advantages, and the demand of a shield machine is also obviously increased. In the process of excavating the shield machine, due to friction between the cutter disc and soil body and reduction of soil in the soil bin, a local high-temperature and high-pressure environment can be generated, under the environment, excavated soil is easy to become relatively hard mud cakes to be attached to the main drive and the cutter disc, and the working efficiency of the shield machine is greatly reduced. When the shield tunneling machine works, soil body cut by the cutterhead falls into a rear soil bin, but a part of space in the center is relatively static, so that a mud cake is easy to form, the soil is scattered by using a carried water spraying pipeline in a traditional mode, but part of soil still adheres to dead zones such as twisting legs of the cutterhead, the more serious the accumulated soil is over time, the cutting efficiency is further influenced, and the construction progress of the shield tunneling machine is influenced.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model provides the auxiliary stirring device which is arranged on the main drive of the shield machine, and water or foam is sprayed through a water spraying pipeline in the stirring rod to soften the auxiliary stirring device, so that the breaking capacity of the device is enhanced, and the problem of mud cake formation in the center of a cutter head of the shield machine is better solved.
In order to solve the technical problem, the utility model provides an auxiliary stirring device carried on a main drive of a shield machine, which comprises a stirring rod, a base, an inner hexagonal screw, a sealing ring, a water pipe and a fixed pipe clamp, wherein the stirring rod and the base are welded into a whole and then are welded and combined with the water pipe; the driving box inner ring is provided with a threaded hole and a sinking groove matched with the base, and the stirring rod and the base penetrate through the hole on the driving box inner ring and are fastened and installed by using an inner hexagon screw.
The stirring rod is perpendicular to the base.
The top of the stirring rod is provided with water spraying ports in two directions.
And a sealing ring is arranged between the base and the cutter head.
The tail part of the water pipe is fixed with the driving box through a fixed pipe clamp.
The beneficial effects are that: according to the utility model, through the relative rotation of the stirring rod fixed on the driving box and the cutter head, stirring of the soil body which is cut inside is realized in the soil bin, the flow of the soil is accelerated, the mud is prevented from forming mud cakes attached to the cutter head to the greatest extent under the high-temperature and high-pressure environment of the soil bin, the continuous working capacity of the shield machine is enhanced, and the water spraying port is formed at the top of the stirring rod, so that the soil body which is difficult to break is softened, and the universality of the device is improved.

Detailed Description
The present utility model will be described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1-3, the utility model provides an auxiliary stirring device carried on a main drive of a shield machine, which comprises a stirring rod 1, a base 2, an inner hexagon screw 3, a sealing ring 4, a water pipe 5 and a fixed pipe clamp 6, wherein the stirring rod 1 and the base 2 are welded into a whole and then are welded and combined with the water pipe 5; the driving box is internally provided with a threaded hole and a sinking groove matched with the base 2 in a surrounding way, and the stirring rod 1 and the base 2 penetrate through the threaded hole on the driving box inner ring and are fastened and installed by an inner hexagon screw 3; when the shield tunneling machine works, the stirring rod 1 and the cutter head relatively rotate, so that stirring of soil body to be cut is realized in the soil bin, the flow of the soil is accelerated, mud is prevented from forming mud cakes attached to the cutter head to the greatest extent under the high-temperature and high-pressure environment of the soil bin, and the continuous working capacity of the shield tunneling machine is enhanced.
The stirring rod 1 is arranged perpendicular to the base 2, so that the longitudinal depth is increased, and the deep slag soil is better removed.
The top of the stirring rod 1 is provided with water spraying ports 7 in two directions, which can soften the soil body which is difficult to break in front and at the side, thereby enhancing the universality of the device.
A sealing ring 4 is arranged between the base 2 and the cutterhead, and sealing capability is guaranteed during water spraying.
The tail of the water pipe 5 is fixed with the driving box through a fixing pipe clamp 6, so that the swing of the water pipe is avoided.
