Hydraulically driven mud pipe turntable device

Abstract

The invention relates to a hydraulic drive mud pipe rotating disc device which comprises a mud pipe, a rocker arm, a jack, a hydraulic winch, a base and a mud pump, wherein the hydraulic winch and the rocker arm are mounted on the base, and connected through the mud pipe; the mud pipe is retracted and extended by rotating the hydraulic winch; the jack is mounted on the rocker arm; the angle of the rocker arm is controlled through extension or retraction of the jack, thereby providing space for main equipment construction; the mud pump is connected with the mud pipe in the hydraulic winch; and through the mud pipe, fresh mud or clear water is conveyed to a specific construction position or a specific depth underground. The hydraulic drive mud pipe rotating disc device can be used as not only mud pipe downward-placement auxiliary equipment for foundation cleaning and mud displacement of underground walls, pile foundations and other underground projects but also auxiliary machinery for washing of a milling wheel for construction during work of a slot milling machine.

Description

technical field [0001] The invention relates to a hydraulically driven mud pipe turntable device, in particular to a mud pipe turntable device with an adjustable rocker arm angle. Background technique [0002] With the continuous development of cities, the development and utilization of underground space has been paid more and more attention by people. The underground diaphragm wall and bored piles constructed with retaining mud are getting deeper and deeper, and it is more and more difficult to retract and retract the mud pipes for construction, and the rack for the mud pipes needs to occupy the upper part of the groove section. If the construction of major equipment such as drilling rigs and slotting machines is hindered, it is usually achieved by directly dragging and dropping the crane. However, in the narrow space where the crane cannot be in place or the site is under construction, it cannot be released. If manual dragging and dropping is used Therefore, it is very ne...

Problems solved by technology

The underground diaphragm wall and bored piles constructed with retaining mud are getting deeper and deeper, and it is more and more difficult to retract and retract the mud pipes for construction, and the rack for the mud pipes needs to occupy the upper part of the groove section. If the construction of major equipment such as drilling rigs and slotting machines is hindered, it is usually achieved by directly dragging and dropping the crane. However, in the narrow space where the crane cannot be in place or the site is under construction, it cannot be released. If manual dragging and dropping is used Therefore, it is very necessary to develop a device that can efficiently retract and retract the mud pipe
