Description

Technical Field

[0001] The utility model relates to the technical field of protection devices for raiseboring machines, and particularly relates to a protection assembly for the oil level gauge of the gearbox of a raiseboring machine. Background Technique

[0002] A raiseboring machine is an efficient underground tunneling device. The hob on the pilot hole bit or the reaming bit makes pure rolling or micro-sliding along the rock working surface at the bottom of the well under the action of the drilling pressure. At the same time, the axial pulling and pressing forces generated by the main engine cylinder also act on the bit, so that the hob teeth impact, extrude and shear the rock, thereby breaking the rock. The raiseboring machine is mainly used for underground shaft construction, such as vertical shafts and inclined shafts in mines, hydropower stations, etc. The gearbox of the raiseboring machine is an important part of the drilling machine, which is responsible for transmitting the power of the motor or hydraulic motor to the drill string system. The oil level gauge of the gearbox is a key component on the gearbox of the raiseboring machine, which is used to monitor the liquid level of the oil in the gearbox. The oil level gauge is usually installed at an easily observable position on the gearbox and is equipped with clear scales or indicator lights so that the operator can understand the liquid level of the oil at any time. The drilling machine is commonly used in an external environment with relatively complex working conditions. The common oil level gauges are protected by relatively ordinary shells, with low protection level, and there may be collisions between other objects and the oil level gauge, damaging the oil level gauge, which is not conducive to the use of the oil level gauge.
