Embodiment 1

[0022] Example 1, such as Figure 1 ~ Figure 4 As shown, the purpose of this embodiment is to provide a hob 5 cutter ring power-assisted rotating device, when the torque generated by the friction force between the hob 5 cutter ring and the palm surface is insufficient, it can provide additional support for the rotation of the hob 5 cutter ring. The power required to avoid the discovery of eccentric wear. At the same time, considering that the cutter head is a precision machine, if the hob 5 cutter ring is driven to rotate, it also needs to consider whether it will affect the use of other structures. Therefore, in order to achieve the above purpose The hob 5 cutter ring power-assisted rotation device provided in this embodiment includes a device body 1 for fixing on the hob 5 cutter box 6. In this embodiment, the device body 1 is in the shape of a hollow convex box Setting, specifically, the device body 1 includes a body portion 11 and a booster portion 12 arranged at one end o...

Abstract

The invention relates to the field of hobs equipped with non-excavation machines such as shield machines, TBMs, and pipe jacking machines, and in particular to a hob cutter ring power-assisted rotation device. It includes a device body used to be fixed on the hob cutter box or the cutter head. The device body is box-shaped. The device body includes a body part and a booster part arranged at one end of the body part. A booster wheel is provided in contact with the hob. The booster wheel is rotated on one side of the booster part through a rotating shaft. One end of the rotating shaft extends into the booster part. A drive for driving the rotating shaft to rotate is arranged in the device body. mechanism. The invention is ingeniously designed and can effectively assist the rotation of the hob, solve the problems of intermittent or complete stoppage of the hob, increase the rock-breaking effect of the hob, prolong the life of the hob, reduce the number of replacement and maintenance of the hob, and save cost.

Description

technical field [0001] The invention relates to the field of hobs equipped with non-excavation machines such as shield machines, TBMs, and pipe jacking machines, and in particular to a hob cutter ring power-assisted rotation device. Background technique [0002] With the development of the national economy, the demand for engineering construction continues to increase, and trenchless machinery is widely used in tunnel projects such as subways, municipal pipe networks, and hydropower. The hob is a rock-breaking tool installed at the front end of non-excavation machines such as shield machines, TBMs, and pipe jacking machines, and the cutter ring is the main working part of the hob for rock breaking. However, due to the complex geology of trenchless construction, it is sometimes soft and sometimes hard, and the top is soft and the bottom is hard. And the hob is installed on the cutter head of the non-excavation machine, and the cutter head is driven to rotate by a high-power ...
