Abstract
The utility model relates to a center muddler of shield tunneling machine shield cutter head mechanism, which is widely applied to subway, railway, road, municipal or hydropower tunnel project. The center muddler is arranged at the center of a seal retaining ring of the shield tunneling machine shield cutter head mechanism, and comprises a cylinder body (1), front/back end sealing caps (2) and a core shaft (3); the cylinder body (1) is fixedly installed the center of the seal retaining ring (6), the core shaft (3) passes through and is connected with the inside of the cylinder (1), the front/back end sealing caps (2) are installed at both ends of the cylinder body (1) in a sealing way; one end of the core shaft (3) is fixed with one end sealing cap of the front/back end sealing caps (2) bya fixed plate (4) and a screw (5), the other end of the core shaft (3) stretches out of the other sealing end cap of the front/back end sealing caps (2). The utility model adds the center muddler tothe center of the seal retaining ring, therefore, the center muddler can automatically remove the soil bond on the seal retaining ring relying on the seal retaining ring self operation to ensure the normal construction of the shield.
Description
(1) technical field
The utility model relates to a kind of shield excavation machine.Be widely used in subway, railway, highway, municipal administration or water power construction of tunnel.Belong to technical field of engineering machinery.
(2) background technology
Shield excavation machine is a kind of special engineering machinery of tunnel piercing.That modern shield structure integrates is mechanical, electrical, liquid, sensing, information technology, has the excavation cutting soil body, carries soil quarrel, the assembly unit tunnel lining, measures function such as the correction of leading.Cutter-head mechanism of shield is the core of shield excavation machine.It mainly is made up of cutter plate driver mechanism, connection supporting leg and cutterhead.Described cutter plate driver mechanism mainly is made up of drive motors, piggyback pod, travelling gear, bull gear, force transmission ring and seal retainer.When shield excavation machine is worked at tunnel excavation, drive motors by cutter-head mechanism of shield transmits power, drive the bull gear rotation by travelling gear, again through force transmission ring be connected supporting leg and drive the cutterhead rotation, cutterhead rotary cutting earth is cut earth and is scattered in the cavity that constitutes between cutterhead and piggyback pod, force transmission ring and the seal retainer.Some local earth viscosity ratio is bigger in the tunnel, and the earth that viscosity is bigger is bonded on the seal retainer easily.After the earth of bonding reaches certain thickness, will influence the normal construction of shield structure.Therefore in the work progress of shield structure, need running check and the artificial earth that is bonded on the seal retainer of removing, to guarantee the normal construction of shield structure.This earth reset mode production efficiency is extremely low.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of center stirring rod that can remove the shield cutter-head mechanism of shield tunnel boring machine that is bonded in earth on the seal retainer at any time automatically is provided.
The purpose of this utility model is achieved in that a kind of center stirring rod of shield cutter-head mechanism of shield tunnel boring machine, described center stirring rod is installed on the seal retainer center of shield cutter-head mechanism of shield tunnel boring machine, comprise cylindrical shell, front and back end capping and mandrel, described cylindrical shell is fixedly mounted on the seal retainer center, the mandrel cross-under is in described cylindrical shell, the front and back end capping is encapsulated in the cylindrical shell two ends, mandrel one end is fixed with an end capping of fixed head and screw and the capping of described front and back end, and the mandrel other end stretches out the other end capping of described front and back end capping.
The beneficial effects of the utility model are: the utility model relies on seal retainer self running by increase by a center stirring rod at the seal retainer center, and the center stirring rod can be removed the earth that is bonded on the seal retainer automatically, guarantees the normal construction of shield structure.
(4) description of drawings
Fig. 1 is the center stirring rod structural representation of the utility model shield cutter-head mechanism of shield tunnel boring machine.
Fig. 2 is Fig. 1 right side view.
Among the figure: cylindrical shell 1, front and back end capping 2, mandrel 3, fixed head 4, screw 5, seal retainer 6.
(5) specific embodiment
Referring to Fig. 1～2, the center stirring rod of the utility model shield cutter-head mechanism of shield tunnel boring machine, this center stirring rod is installed on the seal retainer center of shield cutter-head mechanism of shield tunnel boring machine, is made up of cylindrical shell 1, front and back end capping 2 and mandrel 3.Described cylindrical shell 1 is fixedly mounted on seal retainer 6 centers, mandrel 3 cross-under are in described cylindrical shell 1, front and back end capping 2 is encapsulated in cylindrical shell 1 two ends, mandrel 3 one ends are fixed with an end capping of described front and back end capping 2 with fixed head 4 and screw 5, and mandrel 3 other ends stretch out the other end capping of described front and back end capping 2.
Claims (1)
1, a kind of center stirring rod of shield cutter-head mechanism of shield tunnel boring machine, it is characterized in that: described center stirring rod is installed on the seal retainer center of shield cutter-head mechanism of shield tunnel boring machine, comprise cylindrical shell (1), front and back end capping (2) and mandrel (3), described cylindrical shell (1) is fixedly mounted on seal retainer (6) center, mandrel (3) cross-under is in described cylindrical shell (1), front and back end capping (2) is encapsulated in cylindrical shell (1) two ends, mandrel (3) one ends are fixed with an end capping of described front and back end capping (2) with fixed head (4) and screw (5), and mandrel (3) other end stretches out the other end capping of described front and back end capping (2).
