Drilling and loading vehicle for small-section roadway tunneling and working method

Abstract

The invention discloses a drilling and loading vehicle for small-section roadway tunneling and a working method. The drilling and loading vehicle for small-section roadway tunneling comprises a vehicle frame body, a walking mechanism, a loading and transporting mechanism, a drilling mechanism, a supporting mechanism, a loading and chiseling mechanism and an operation control mechanism, and the walking mechanism, the loading and transporting mechanism, the drilling mechanism, the supporting mechanism, the loading and chiseling mechanism and the operation control mechanism are installed at the bottom of the vehicle frame body; the drilling mechanism uses a multi-degree-of-freedom mechanical arm to be connected with a drilling machine unit and a facing unit, and the drilling adaptation directions are multiple; and the facing unit is used for facing uneven sections, and convenience is provided for drilling work. The supporting mechanism supports a roadway roof during anchoring work, and safety and stability in the anchor hole drilling process are guaranteed. After drilling and blasting, the loading and chiseling mechanism is used for coal seam section coal scraping operation, and then the loading and transporting mechanism is used for transferring, clearing and transporting, so that drilling, loading and transporting are integrated; the operation control mechanism is used for controlling components; and when the drilling mechanism and the supporting mechanism work, a control system does not need to manually control the working state, safety is guaranteed, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of coal mine machinery technology, and in particular relates to a drill loading vehicle and a working method for excavating a small-section roadway. Background technique [0002] At present, in the construction process of mine roadways and engineering tunnels, large-scale shield machines or roadheaders are generally used to carry out operations; but in the same narrow excavation face, large shield machines or roadheaders cannot be used. Most of the rock roadways where the equipment is used for operation use a single drill car, a single loading car and a single bolter, and complete the entire excavation process through the cooperation of multiple machines. This construction method requires more equipment and low operating efficiency. And a series of problems with high security risks. [0003] The drilling and loading trucks currently on the market can complete drilling and loading in one, but they cannot pro...

Problems solved by technology

[0002] At present, in the construction process of mine roadways and engineering tunnels, large-scale shield machines or roadheaders are generally used to carry out operations; but in the same narrow excavation face, large shield machines or roadheaders cannot be used. Most of the rock roadways where the equipment is used for operation use a single drill car, a single loading car and a single bolter, and complete the entire excavation process through the cooperation of multiple machines. This construction method requires more equipment and low operating efficiency. and a series of problems with high security risks

[0003] The drilling and loading trucks currently on the market can complete drilling and loading, but they cannot protect the working section during the working process; their working freedom is low, and they still cannot completely solve the problems encountered in the construction process of small-section roadways. question
