Description

Technical Field

[0001] The utility model belongs to the technical field of shield machines, and particularly relates to a high-precision turning angle control device for a shield machine. Background Art

[0002] A shield machine (TBM) is a tunnel boring machine that uses the shield method. The machine constructs (or lays) the tunnel's "shield" (supporting segments) while tunneling. During tunneling, the machine often needs to make turns, requiring the cutterhead to adjust its turning angle. This is accomplished using a control panel inside the control room, which typically features various buttons, including push-button, rotary, and joystick controls.

[0003] Since the rocker-type keys need to reserve various angles of inclination for the rocker, the connecting grooves thereon are often open and a large space is reserved. Therefore, dust in the air can easily enter the interior of the connecting grooves, affecting the use of the rocker. Moreover, as the rocker is used for a long time, its internal damping will gradually change due to wear, which is not conducive to personnel's control of the rocker. The above disadvantages are not conducive to personnel's high-precision adjustment of the turning angle. Therefore, it is necessary to design a new control device to solve this problem. Utility Model Content

[0004] The purpose of the present utility model is to provide a high-precision turning angle control device for a shield machine, so as to solve the problem proposed in the above background technology that the rocker-type buttons on the control platform have poor dustproof effect and are difficult to control after long-term use, thereby affecting the control accuracy.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A device for controlling the high-precision turning angle of a shield machine, comprising a platform body and a display connected to the top of the rear end of the platform body, the surface of the display being provided with buttons and rocker keys, the rocker keys comprising a connecting pile, a rocker, a connecting cover, a rubber movable cover, a threaded rotating ring and a give-way groove, the connecting pile being fixed to the surface of the platform body, the connecting cover being connected to the top of the connecting pile, the give-way groove being provided inside the connecting cover, the bottom end of the rocker passing through the give-way groove and extending into the interior of the connecting pile, the threaded rotating ring being threadedly connected to the surface of the rocker, the rubber movable cover being connected to the bottom of the threaded rotating ring and in contact with the upper surface of the connecting cover.

[0006] Preferably, the top surface of the connecting cover is an arc-shaped structure, and the rubber movable cover is a matching arc-shaped structure.
