Anti-overturning moment assembling machine and shield tunneling machine

Technical Field

The utility model belongs to the technical field of a shield constructs quick-witted technique and specifically relates to a prevent moment of toppling erector and shield constructs machine.

Background

The assembling machine is an important component of the shield machine and is mainly used for completing segment hoisting and assembling work in tunnel excavation. In the prior art, the assembling machine mainly comprises a rotating assembly and a lifting and horizontal moving assembly, wherein the rotating assembly is rotatably arranged in a shield body through a supporting wheel and a guide wheel. The lifting and horizontal moving component is mainly used for finishing the grabbing, lifting and assembling actions of the duct piece, is used as an integral part, is fixedly connected to one side of the rotating component and rotates along with the rotation of the rotating component. For in the balanced rotation, promote and the rotatory moment influence that the horizontal migration subassembly produced to the rotating assembly, the last balancing weight that is provided with of rotating assembly, balancing weight and promotion and horizontal migration subassembly are located rotating assembly's homonymy, and are symmetrical arrangement on rotating assembly's disc. The splicing machine in the prior art has the following defects: because the lifting and horizontal moving component is fixedly arranged on one side of the rotating component and exceeds the supporting range of the supporting wheel, the lifting and horizontal moving component has harmful influence on the overturning moment generated by the rotating component, so that the splicing machine is easy to shake or make abnormal sound in work, and further the stable work of the splicing machine is influenced.

Because the weight of the lifting and horizontal moving component arranged on one side of the rotating component is lightened due to the change of the installation positions of the components, the adverse effect of the overturning moment generated by the rotating component is reduced, meanwhile, because the components are arranged on the other side of the rotating component in a transferring way, the anti-overturning moment is generated on the rotating component, the direction of the adverse effect is opposite to the adverse effect of the overturning moment born by the rotating component, and the adverse effect of the overturning moment born by the rotating component can be effectively counteracted. Therefore, the position of the component is moved, the adverse effect of the lifting and horizontal components on the overturning moment generated by the rotating component can be excellently eliminated, and the cost is not increased.

As the utility model discloses a further improvement, for further guaranteeing the steady operation of erector, the rotating assembly does not bear the moment harmful effects that topples, and the rotating assembly is provided with prevents the device that topples, prevents that the device that topples is slide slider structure, and the slide is closed ring shape, fixed mounting shield internal surface, and the slider is fixed in on the rotating assembly to slidable installs in the slide. When the rotating assembly rotates, the sliding block slides in the annular slide way to play a certain guiding role in the rotating assembly. In operation, when the rotating assembly is affected by the overturning moment generated by the lifting and horizontal moving assembly, the annular slide way generates an anti-overturning effect opposite to that of the slide block. The two directions are opposite and offset with each other, so that the adverse effect on the overturning moment generated by the lifting and horizontal moving component on the rotating component can be improved or eliminated. In order to further ensure the slide way slide block structure and improve or eliminate the effect of harmful influence of the overturning moment borne by the rotating assembly, the slide blocks are at least more than two and are symmetrically and uniformly arranged on the rotating assembly.

The utility model also provides a shield constructs machine of preventing moment erector that topples with above-mentioned technical characteristic.
