Mining machinery industry-rock drilling jumbo
- Commodity name： Mining machinery industry-rock drilling jumbo
- Product Description
Drilling jumbo (also known as drilling jumbo) is a kind of drilling equipment used in tunnel and underground engineering construction by drilling and blasting method. It can move and support multiple rock drills simultaneously. The working mechanism is mainly composed of propeller, drill arm, rotary mechanism and translation mechanism. Rock drilling trolleys can be divided into flat roadway tunneling drilling trucks, mining drilling trucks, anchor rod drilling trucks and open rock drilling trucks, etc. According to the walking mechanism of the drilling truck, it can be divided into rail wheels, tires and crawler type. According to the number of rock drills erected, it can be divided into single, double and multi-machine drilling trucks. The development status, working organization, classification, application, fault analysis and development trend of the system at home and abroad are introduced in detail.
The working hydraulic system of the rock drilling rig adopts an electric proportional multi-way valve, and the load-sensitive pump realizes the load-sensitive open system to realize the attitude adjustment of the boom and the rotation, propulsion and impact of the rock drilling rig. The use of load sensing system makes the hydraulic system more energy-saving, and the electric proportional multi-way valve accurately controls the attitude adjustment of the boom frame.
