Description

Technical Field

[0001] The utility model belongs to the technical direction of shield engineering auxiliary equipment, and particularly relates to a shield construction muck transfer device. Background Technique

[0002] A shield tunnel boring machine, abbreviated as a shield machine, is a special construction machinery for tunnel boring. Modern shield boring machines integrate optics, mechanics, electricity, hydraulics, sensors, and information technology, and have functions such as excavating and cutting soil, transporting muck, assembling tunnel linings, and measuring and guiding deviation correction. It involves multiple disciplines such as geology, civil engineering, machinery, mechanics, hydraulics, electricity, control, and measurement, and needs to be "tailored" designed and manufactured according to different geological conditions, with extremely high reliability requirements. Shield boring machines have been widely used in tunnel projects such as subways, railways, highways, municipal engineering, and hydropower. During shield construction, muck transfer generally uses a shield belt conveyor to discharge muck. Usually, the shield belt conveyor is connected and transferred to a transfer belt conveyor, and then poured into a transfer device for transfer.

[0003] Chinese patent document CN215206550U discloses a shield construction muck transfer device, including a base, a protective frame, a box body, a cover plate, a stabilizing member, and a stabilizing device. In the utility model, stabilizing devices are installed at the front and rear ends and the left end of the protective frame. An independent motor is installed inside the stabilizing device, and the motor drives the internal pushing mechanism to transmit power. The pushing mechanism can push out the pressing mechanism on the left side to contact the right arm of the belt conveyor, improving the stability of the box body during the process of receiving muck. A spring is installed inside the pressing mechanism, which can buffer the impact force after contact and improve the overall stability.

[0025] First, fix the lift fixing plate 5 under the lift, then fix the muck transport vehicle 1 filled with muck under the lift fixing plate 5 through the four fixed connection components 4, and then move and unload the muck transport vehicle 1 under the action of the lift. After completion, lift the muck transport vehicle 1 back to the underground track, and through the action of the moving wheels 3 and the track, move the muck transport vehicle 1 under the shield machine for loading.

[0026] As Figures 2-5 shown, the automatic recovery component 2 includes a reinforcing plate 21.

The inner wall of the lower part of the reinforcing plate 21 is rotatably connected to the outer wall of the moving wheel 3. A moving block 22 is slidably connected to the inner cavity of the reinforcing plate 21;

[0027] Through the action of the reinforcing plate 21, the four corners of the muck transport vehicle 1 are strengthened and fixed, so that it can move stably on the track under the action of the moving wheels 3.

[0028] The fixed connection component 4 includes a steel rope 41. The lower surface of the steel rope 41 is fixedly connected to the upper surface of the moving block 22. The outer wall of the steel rope 41 is movably sleeved with the inner cavities of the reinforcing plate 21 and the muck transport vehicle 1 respectively.
