Problems solved by technology

This blasting excavation method has many construction disadvantages, for example, it has harmful effects on the surrounding environment and surrounding rock, and the flying stones and gun smoke generated during the blasting process make tunnel excavation only intermittent operations
As a result, the utilization rate of drilling, ballasting, support and other operation time is greatly affected
[0003] In addition, in the construction of traditional drilling and blasting method, there are vibrations, flying stones, shock waves, noise, harmful gases and other influences during the construction process, so that the blasting construction will cause uneven defects on the tunnel surface. problems, increased support workload, low construction efficiency and poor safety performance

Abstract

The invention provides a drill splitting trolley for tunnel excavation. The drill splitting trolley comprises a chassis, a drill splitting device, a splitting device, an electrical system and a hydraulic system; a frame is arranged on the chassis; the drill splitting device and the splitting device which are respectively used for drilling and splitting rocks are mounted on the frame; the electrical system and the hydraulic system are arranged on the chassis, the electrical system is used for controlling operation of the drill splitting device and the splitting device, and the hydraulic systemis used for providing power to the drill splitting device and the splitting device; the drill splitting device and the splitting device are integrally mounted at the front end of the frame and are respectively located on the upper portion and the lower portion of the front end of the frame, and under the action of the electrical system and the hydraulic system, the drill splitting device and the splitting device adopt a transposition mechanism to perform drilling and splitting the rocks in turn. The drill splitting trolley adopts multi-freedom operation arms, which have high controllability, wide construction range, high construction efficiency and high safety performance.

Description

technical field [0001] The invention relates to the technical field of excavation equipment in tunnel construction engineering, in particular to a drilling and splitting jumbo used for tunnel excavation. Background technique [0002] At present, the excavation of short and medium length hard rock tunnels is dominated by the drill and blast method. During tunnel excavation construction, firstly, blast holes are drilled, and then excavated by explosive blasting. This blasting excavation method has many construction disadvantages. For example, it has harmful effects on the surrounding environment and surrounding rock, and the flying stones and gun smoke generated during the blasting process make tunnel excavation only intermittent operations. As a result, the utilization rate of operation time such as drilling, ballasting, and support is greatly affected. [0003] In addition, in the construction of traditional drilling and blasting method, there are vibrations, flying stones...
