Telescope feed type manipulator in backhoe digging, and application in tunnel shield machine and pipe pushing jack

Abstract

The present invention discloses a kind of sleeve counter shoveling and excavating manipulator and its application in shield machine and push bench. The present invention on structure mainly replaces the connecting rod organ in traditional excavator with gearing hydraulic pressure. It's comprised of support of rotation, extension sleeve, bucket device, moveable arm cylinder, shakeable pole cylinder, bucket cylinder and turning cylinder. The movement of its excavating device is also mainly drove by the extension of cylinder, therefore the said sleeve counter shoveling and excavating manipulator is provided with the advantages as occupying small space, high structure intensity and rigidity, and strong excavating force. Besides the renewable percussive drill makes the present invention have staving function, which can adopt more soil textures of excavation. The present invention provides more suitable excavating mechanism for shield and push excavator in tunnel construction, so it makes the excavator be able to adapt various soil layer, reduce workers' work intensity, and improve the constructing efficiency.

Description

technical field [0001] The invention relates to an excavating machine, in particular to a sleeve type backhoe excavating manipulator and its application. Background technique: [0002] Excavation machinery and its structure are one of the important technologies of engineering construction machinery. At present, the excavating machinery widely used at home and abroad is the connecting rod excavator, and the movement and power transmission mechanism of the excavating bucket are mainly connecting rod mechanisms. In order to expand the working range of the bucket as much as possible to meet the needs of excavation work, the link mechanism as a transmission motion must be designed to be very large, not only its own volume is large, but also the space required for its work is also very large. In addition, the link mechanism mainly relies on the principle of leverage to transmit power, so it is difficult for the link excavator to achieve a large digging force due to the limitation...

AI Technical Summary

Problems solved by technology

[0011] It can be seen from the content disclosed in the invention that the main transmission mechanism for realizing the large working range of the excavating tool is still the connecting rod mechanism, but hydraulic cylinders are used on some connecting rods. Therefore, the technical solution of the invention It still inevitably has the disadvantages of large space occupation, small digging force, and low structural strength and rigidity similar to the link excavator
