Rectangular jacking pipe tunneling machine combined type gearbox

Abstract

The invention discloses a rectangular jacking pipe tunneling machine combined type gearbox which comprises a base. A gearbox body is installed on the base through screws. A second input shaft is installed on the gearbox body through a bearing. A first gear is installed on the second input shaft. The first gear and a second gear are engaged. The second gear is installed on a transmission shaft. A third gear is installed on the transmission shaft. The third gear and a fourth gear are engaged. The fourth gear is installed on a second output shaft. The second input shaft is connected with a firstoutput shaft of a planetary reducer through a coupler. The planetary reducer comprises an inner tooth ring. A front end cover is installed on the front side of the inner tooth ring through screws. A rear end cover is installed on the rear side of the inner tooth ring through screws. The planetary reducer is in butt joint with the two-level reducing gearbox to form a combined type reducer, while the requirement of output torque is met, the transverse occupied area is reduced, and a jacking pipe tunneling machine can be assembled conveniently.

Description

technical field [0001] The invention relates to the technical field of pipe jacking machines, in particular to a combined gearbox of a rectangular pipe jacking machine. Background technique [0002] With the development of domestic underground engineering, since the effective use area of ​​the rectangular section is about 20% larger than that of the circular section, the pipe jacking machine adopts the rectangular pipe jacking machine with a rectangular section to make the space utilization of the tunnel more reasonable and economical. Rectangular pipe jacking machine is a highly mechanized and automated excavation and lining complete set of equipment that adopts shield method and integrates mechanical, electronic, hydraulic, laser and control technologies. The cylinder is advanced to make the cutter head close to the soil wall under a certain pushing force, and the soil is excavated through the disc-shaped hob installed on the cutter head. The cutter head of the pipe jacki...

AI Technical Summary

Problems solved by technology

The cutter head of the pipe jacking machine is driven by the motor through the gearbox, and the gearbox plays the role of reducing the speed and increasing the torque. Because the cutter head often encounters rock layers in the process of digging forward, the cutter head needs The torque is very large, and the gearbox needs to be decelerated in multiple stages to achieve the required torque. The more stages of deceleration, the larger the volume of the gearbox body. The pipe jacking machine is mainly used for excavating municipal pipelines with a small cross-sectional area. , so the volume of the gear box is too large, which will compress the installation space of other components, resulting in inconvenient installation
