Embodiment Construction
[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0037] refer to figure 1 , the present invention provides a floating hinged device for a screw conveyor. When the shield machine turns with a small radius, the sleeve and the front tank generate relative motion to adapt to the turning conditions of the shield machine, and the sleeve When there is a relative displacement between the front tank and the front tank within a certain range, reliable sealing can be ensured, which greatly improves the sensitivity of the screw machine. The main body of the screw conveyor is supported by the middle shield of the shield machine, the sleeve is connected with the front shield of the shield machine, the front tank is connected with the main body of the screw conveyor, and the sleeve and the front tank are movably connected by a connecting rod. Make relative movement between the sleeve and the front tank bod...

The invention relates to a floating type hinge device of a screw conveyer. The floating type hinge device comprises a front groove body arranged on a screw conveyer body in a sleeving manner, a sleevearranged on the front groove body in a sleeving manner and a connecting rod for movably connecting the front groove body with the sleeve; the front groove body is fixedly connected with the screw conveyer body, the sleeve is fixedly connected with an anterior shield of a shield tunneling machine, a sealing structure is fixedly arranged on the end face, far away from the anterior shield of the shield tunneling machine, on the sleeve, and a gap between the sleeve and the front groove body is sealed through the sealing structure; and movable connection of the connecting rod enables the front groove body and the sleeve to be capable of achieving relative motion so as to adapt to the working condition of turning of the shield tunneling machine. A new hinge manner is provided, and the beneficial effects of the simple structure and low cost are achieved. When the shield tunneling machine makes a turn, the sleeve and the front groove body are connected through the connecting rod to form the hinge device, the sensitivity of the screw conveyer is increased, and the screw conveyer can be suitable for the working condition of small radius turning of the shield tunneling machine.
Description
technical field [0001] The invention relates to the field of shield tunnel construction, in particular to a floating hinged device of a screw conveyor. Background technique [0002] In China, shield tunneling machines have been widely used in the construction of subways, large-diameter tunnels, and underground pipelines due to their excellent ground subsidence control, high excavation efficiency, and wide-ranging ground adaptability. [0003] The screw conveyor is the equipment used on the shield machine to transport the soil excavated by the cutter head. When the shield machine needs to turn with a small radius, the front and rear sections of the shield machine will produce relative motion, so the screw conveyor needs to be equipped with hinges. device. The existing screw machine hinge usually adopts a ball joint device, and the structure of the ball joint device is complicated and the cost is high. Contents of the invention [0004] The purpose of the present invention...
