Problems solved by technology

[0002] In the known technology, the drilling blasting method is widely used in the roadway or tunnel excavation operation, and the blasting is used to break the rock around the blasthole. This operation method has high operating costs, high risk, low efficiency, and slow excavation speed.
In addition, the rock structure is damaged by blasting, which increases the probability of landslides and increases the difficulty of subsequent roadway restoration.
In the construction of large-scale tunnels, some full-face tunnel boring machines are used for tunneling operations, and the rocks on the working surface are ground by the rotation of the cutting disc. The operation efficiency is low, the power consumption is large, the operating cost is high, and the cutting products are useless gravel
Chinese patent application No. 96113151.9 discloses a technical solution of a "chainsaw shearer roadheader cutting device". cut

Embodiment Construction

[0012] The excavation and cutting device includes a sleeve (5), a power structure, a transmission structure and a cutting structure. The power structure drives the sprocket shaft (9) to rotate through the transmission structure, and the driving sprocket (10) is connected with the chain saw (11) from Driven sprocket (13) rotates, and chain saw (11) rotates and cuts, and driven sprocket (13) and square key (15) movably cooperate to connect cutting shaft (14).

[0013] The sleeve (5) is integrally set in the orientation groove (23) of the carriage (22). The frame car (22) is provided with a switcher (19), and the switcher (19) locates the horizontal or vertical frame car orientation slot (23) of the switch frame car (22) with the switcher rotating shaft (18). Driven sprocket wheel (13) and square key (15) cooperate to connect cutting shaft (14) with square key fixed pin (16) positioning activity through square key dial hole (17). In the power structure, the rotating shaft of the...

Abstract

A chain saw type tunnelling machine is composed of sleeve pipe, power unit, drive unit and cutting unit. The power unit drives via drive unit the chain gear axle. The driven chain gear is linked with driven chain gear via chain saw. Its advantages are simple structure, 3D cutting and less vibration damage.

Description

technical field [0001] The invention belongs to operating machinery, and in particular relates to a chainsaw type roadway excavation and cutting device. Background technique [0002] In the known technology, the drilling blasting method is widely used in roadway or tunnel excavation, and blasting is used to break the rocks around the blasthole. This operation method has high operating costs, high risk, low efficiency, and slow excavation speed. Moreover, the rock structure is damaged by blasting, which increases the probability of landslides and makes it more difficult for subsequent roadway reconstruction. In the construction of large-scale tunnels, some full-face tunnel boring machines are used for tunneling operations, and the rocks on the working surface are ground by the rotation of the cutting disc. The operation efficiency is low, the power consumption is large, the operating cost is high, and the cutting products are useless gravel. Chinese patent application No. 96...
