Description

Technical Field

[0001] This utility model relates to the field of slewing bearing maintenance technology, and in particular to a slewing bearing maintenance device for tunneling machines. Background Technology

[0002] The slewing bearing of a tunneling machine, also known as a turntable bearing, slewing bearing, or rotary bearing, is a large bearing capable of withstanding comprehensive loads. It mainly consists of inner and outer rings and rolling elements. The outer ring is connected to the machine body of the tunneling machine through a threaded hole on the outer ring, and the inner ring is connected to the turntable of the tunneling machine through a threaded hole on the inner ring. The cutting part of the tunneling machine is installed on the turntable, allowing the cutting part to be adjusted in the horizontal direction.

[0003] During the use of tunneling machines, groundwater and coal dust can enter the slewing bearing through gaps. Water can cause the slewing bearing to rust, and the water can mix with the lubricating oil and harden together with the coal dust. If the equipment is not used for a long time, the slewing bearing will often become unable to rotate. It is necessary to soak it in kerosene for a long time, and then several workers have to use crowbars to pry it and hammer it to vibrate it. Only after repeated operations can the slewing bearing be moved and rotated again. The operation process is time-consuming and labor-intensive, which seriously affects production efficiency.

[0004] Therefore, a convenient maintenance device for the slewing bearing of a tunneling machine is needed. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a tunneling machine slewing support maintenance device that uses two reciprocating and counter-rotating turntables to drive the inner and outer rings of the slewing support to reciprocate and counter-rotate, thereby causing the slewing support to vibrate and loosen and dislodge the dust and impurities that have accumulated inside the slewing support. This device is simple, efficient, safe, reliable, and easy to operate.

[0006] This utility model is achieved through the following technical solution: a maintenance device for a tunneling machine's slewing bearing is provided, including a base, a sliding groove on the base, a support mounted on the sliding groove, and a turntable with its axis extending axially along the sliding groove on the support, the turntable being located on the opposite side of the support; the turntable is provided with several support rods with their axes extending axially along the turntable, the support rods being located on the opposite side of the turntable, and the support rods on the two turntables are respectively adapted to the screw holes on the inner and outer rings of the slewing bearing; the two turntables, which rotate in opposite directions, drive the inner and outer rings of the slewing bearing to rotate in opposite directions, thereby causing the slewing bearing to vibrate, which in turn loosens and removes the dust and impurities that have hardened inside the slewing bearing.

[0007] As an optimization, a slide bar extending radially along the turntable is fixed to the turntable, and a slider is slidably mounted on the slide bar, with a support rod located on the slider; the position of the support rod can be easily adjusted according to the size of the slewing bearing through the slide bar and slider.

[0008] As an optimization, adjacent sliders are connected by telescopic rods, and the distance between each slider and the axis of the turntable is equal; the telescopic rods provide support for the sliders to prevent deformation of the rods.

[0009] As an optimization, the end of the slide bar furthest from the turntable is connected sequentially by a retaining ring; the retaining ring provides support to the slide bar to prevent deformation.

[0010] As an optimization, the support rod is mounted on a turntable, and the support rods on the two turntables are respectively provided with threads that are compatible with the corresponding screw holes; the threads are used to make the support rod and the screw holes compatible, thus preventing wear of the screw holes.

[0011] As an optimization, a collection tray is provided on the base, which is located directly below the slewing support, and the angle formed by the axis of the collection tray and the horizontal plane is less than 90°; the collection tray collects dust and other impurities that fall off the slewing support.

[0012] The beneficial effects of this utility model are as follows: the two reciprocating rotating discs drive the inner and outer rings of the slewing support to reciprocate in opposite directions, thereby causing the slewing support to vibrate, which in turn loosens and dislodges the dust and impurities that have hardened inside the slewing support; the sliding rod and slider facilitate the adjustment of the position of the support rod according to the size of the slewing support; the telescopic rod provides support force to the slider to prevent deformation of the sliding rod; the fixing ring provides support force to the sliding rod to prevent deformation of the sliding rod; and the threaded connection allows the support rod and the screw hole to be matched to prevent wear of the screw hole.
