Embodiment Construction

[0022] Such as figure 1 As shown, the rock-breaking device of the present invention mainly includes a rotary table 1, a rock-breaking arm (the telescopic outer arm 2 of the rock-breaking arm, and the telescopic inner arm 3 of the rock-breaking arm) and a breaking hammer 4, and one end of the rock-breaking arm is connected to the rotary table 1. The other end of rock arm is connected breaking hammer 4. The turntable 1 is installed on the carrier through the slewing bearing, and the turntable 1 is driven by a hydraulic cylinder or a hydraulic motor, which can realize the deflection around the rotary axis; the rock-breaking arm is a telescopic arm structure, which is driven by the hydraulic cylinder to realize the expansion and contraction of the rock-breaking arm. In this embodiment, the rock-breaking arm is a telescopic arm structure formed by connecting the telescopic inner arm 3 of the rock-breaking arm and the telescopic outer arm 2 of the rock-breaking arm. One end of 5 is...

Abstract

The invention relates to the field of excavation equipment, in particular to a rock-breaking device for tunnel construction or roadway excavation. The device is provided with a turntable, a rock-breaking arm and a breaking hammer. One end of the rock-breaking arm is connected to the turntable, and the other end of the rock-breaking arm is connected to the breaking hammer. The turntable is installed on the carrier through the slewing bearing. The turntable is driven by a hydraulic cylinder or a hydraulic motor. The rock-breaking arm is a telescopic arm structure composed of a telescopic inner arm of the rock-breaking arm and a telescopic outer arm of the rock-breaking arm. The outer end of the telescopic outer arm of the rock-breaking arm is hinged with the rotary table, and the vertical pitch of the equipment can be realized under the push of the hydraulic cylinder; the end of the telescopic inner arm of the rock-breaking arm is hinged with the breaker, and it can be flexibly Adjust the impact angle of the breaking hammer. The present invention overcomes the shortcomings of the drilling and blasting method and the comprehensive tunneling method, realizes the purpose of tunnel construction and roadway excavation with a breaker, realizes rapid and efficient tunneling of superhard whole rock roadways without blasting, and avoids major accidents from the root happened.

Description

technical field [0001] The invention relates to the field of excavation equipment, in particular to a rock-breaking device for tunnel construction or roadway excavation. Background technique [0002] In the construction of tunnels, roadways and underground projects in our country, medium and hard rock construction accounts for a considerable proportion. The drilling and blasting method and the comprehensive tunneling method are two commonly used construction methods for hard rock tunnels and roadways. However, the drilling and blasting method has low efficiency and poor safety. Improper operation can easily cause gas explosions. It is also difficult to control the quality of roadway formation, and serious overbreak and undercut. The comprehensive excavation method has relatively high requirements on the roadway, the rock hardness cannot exceed f8, the height of the roadway should not be less than 3.0 meters, and the width should not be less than 4 meters. If the hardness of...
