Abstract

The invention discloses a horizontal jet grouting drilling machine which comprises a drilling machine platform and a lifting arm, wherein rotary working devices are arranged at the front end and rear end of the drilling machine platform; each of the rotary working devices comprises a fixing base, a rotating base, a gear motor and a rotary support with teeth on external circle and without tooth on internal circle; the fixing base is fixedly connected with the drilling machine platform; the rotating base is fixedly arranged at the bottom end of the lifting arm; the gear motor is arranged on the rotating base; the internal circle of the rotary support is fixedly connected with the rotating base; the external circle of the rotary support is fixedly connected with the fixing base; the external circle of the rotary support is meshed with the teeth of the gear motor; the gear motor is used for driving the rotating base and the lifting arm to swing so as to drive a cantilever crane to swing; front and rear dual rotary working devices are adopted for synchronously driving the cantilever crane to swing, so that sufficient power can be supplied to the machine for swinging under various working conditions, the rotating angle of the cantilever crane can be guaranteed, the machine can meet the construction requirement, the machine stability can be guaranteed, the machine loss is less, the construction quality is guaranteed and the construction safety is promoted.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering machinery, in particular to a horizontal jet jet drilling machine. Background technique [0002] In the current tunnel engineering construction, there are various construction machinery products suitable for various construction methods, among which the horizontal rotary jet drilling machine is the most commonly used one. [0003] At present, most of the rotary excavation of tunnels adopts the rotary mode of the single-drive working device. Since the direction of the center of gravity of the horizontal rotary jet drilling rig deviates during side excavation, the stability decreases. In order to meet the requirements of rotary torque, pressing force, and speed, the rotary drive device It is easy to twist, jitter and stick. This single-drive rotary method not only limits the openness of the design of the working device, but also causes greater wear and tear and a short life cycle of the ...
