Mechanically-driven hard-rock double-head tunneling machine

Abstract

The invention relates to a mini tunneling machine, in particular relates to a mechanically-driven hard-rock double-head tunneling machine which comprises a traveling device and a shovel plate device, wherein a machine body device is arranged on the traveling device, a double-head tunneling device is arranged on the rotating mechanism of the machine body device, the shovel plate device is arranged at the front end of the machine body device through a shovel plate supporting mechanism, an operating and control mechanism and a driving mechanism are arranged on the two sides of the machine body device respectively, the shovel plate supporting mechanism and the rotating mechanism are independently connected with one end of a hydraulic line mechanism which is arranged on the machine body device, and the other end of the hydraulic line mechanism is connected on the operating and control mechanism. Accordingly, the overall structure is optimized, the mechanical drive mode is adopted to ensure stable working performance, the service life of the equipment is increased, and the hard-rock tunneling efficiency is increased by more than 50%.

Description

Technical field [0001] The invention relates to a small heading machine, in particular to a mechanical transmission type hard rock double heading head heading machine. Background technique [0002] The small hard rock roadheader is a kind of excavation equipment that integrates cutting, loading and transferring gravel. It is connected in structure and light in size. It is widely used in transportation, tunneling, mining and other fields. Compared with large roadheaders, With the characteristics of small size and light weight, it is suitable for medium and small coal mine operations and is beneficial to improve the level of mechanization. The small hard rock roadheaders currently used mainly have the following shortcomings: [0003] In terms of tunneling head devices, hydraulically driven single tunneling heads are adopted. This setting method generally has the following shortcomings: First, the working efficiency is relatively low, the hydraulic oil consumption is relatively large...

AI Technical Summary

Problems solved by technology

[0007] The present invention is to solve the above-mentioned problems such as low working efficiency and unreasonable body structure setting of the roadheader, and provides a novel mechanically driven small-sized hard rock double-head roadheader, which optimizes the structure of the whole machine and adopts mechanical The transmission makes the working performance stable, prolongs the service life of the equipment, and increases the driving efficiency of hard rock by more than 50%.
