Problems solved by technology

[0002] With the continuous development of underground space construction and the increasing demand for underground space, the demand for the diameter of the shield machine is also increasing. The ten-meter vertical lathe is used to process the conventional shield body. Theoretically, the ten-meter large-diameter shield body is The processing limit of the 10-meter vertical lathe, but the weight of the front middle shield of the shield body with a diameter of 8600mm is 160 tons in actual conditions, which is already the load limit of the ten-meter vertical lathe. When the ten-meter vertical lathe is processing the front middle shield of the 8600mm shield body, Turning over twice and assembling three times not only caused the deformation of the shield body to affect the machining accuracy, but also slowed down the cutting speed, which led to an increase in workload and could not meet the needs of shield machine processing

Abstract

The invention provides a vertical lathe special for machining a large-diameter shield body and relates to the field of shield machine devices. The vertical lathe special for machining the large-diameter shield body comprises a working table supporting plate, a working table installed on the working table supporting plate in a rotating manner, a supporting base in an inverted circular truncated cone shape, multiple shield body supporting stand columns arranged at intervals in the peripheral direction of the working table, a machining tool, and a feeding assembly used for driving the machining tool to be lifted and moving in the horizontal straight line, wherein the supporting base is detachably connected to the working table. The feeding assembly is arranged to be detachably connected to the top edge of the working table or the top edge of the supporting base. A revolution assembly used for driving the working table to rotate is further connected to the working table. According to the vertical lathe special for machining the large-diameter shield body, all the shield body is machined in place through one-time clamping, potential safety hazards caused to the large-diameter shield body due to multiple times of clamping are avoided, machining precision can be improved, and the earlier and middle shield machining period of the large-diameter shield body is shortened.
