The Underground jambo is a kind of rock drilling equipment that uses the drilling and blasting method to construct tunnels and underground projects. It can move and support multiple rock drills to perform drilling operations at the same time. The working mechanism is mainly composed of a propeller, a drilling boom, a slewing mechanism, and a translation mechanism. Next, I will introduce you to the Underground jambo.
Here is the content list:
What are the composition and classification of Underground jambos?
What constitutes the working mechanism of the Underground jambo?
What is the development trend of Underground jambos?
It is mainly composed of rock drill, drill boom (supporting, positioning, and propelling mechanism of rock drill), steel frame, running mechanism, and other necessary auxiliary equipment, and equipment added according to engineering needs. Underground jambos can be divided into roadway boring rigs, mining rigs, bolt rigs, and open-pit Underground jambos, etc.; according to the walking mechanism of the rig, it can be divided into rail wheel, tire, and crawler type; The number of erected rock drills can be divided into single, dual and multi-rig drilling rigs. It introduced in detail its domestic and international development status, work organization, classification, application, failure analysis, development trend, etc.
The working mechanism is mainly composed of a propeller, a drilling boom, a slewing mechanism, and a translation mechanism.
1. A thruster
The propellers of Underground jambos mainly include steel rope piston type, wind motor piston type, and pneumatic screw pair type. The role of the propeller of the Underground jambo is to enable the rock drill to quickly drive to the working surface when preparing to open a hole and to give the rock drill a certain axial thrust when drilling the rock.
2. Drill boom
The boom of the rock drill rig is the working boom that supports the rock drill. The boom structure and size of the rock drill rig, the flexibility, and reliability of the boom action, etc., will affect the scope of application and production capacity of the rock drill rig.
3. Slewing mechanism
The slewing mechanism of the Underground jambo can be divided into several types: swing type rotary column, spiral pair type rotary column, and polar coordinate drill arm slewing mechanism. Generally speaking, the swinging column has a simple structure, reliable work, and convenient maintenance.
4. Propeller translation mechanism
There are two types of translation mechanisms commonly used in Underground jambos: mechanical translation mechanisms and hydraulic translation mechanisms. There are several types of mechanical translation mechanisms: scissor, planar four-bar linkage, and spatial four-bar linkage; hydraulic translation mechanisms with or without translation guide cylinder type and translation guide cylinder type.
The development trend of fully automatic users of Underground jambos: With the development and application of hydraulic control and electronic technology, the rock drilling cycle has been automated, that is, automatic drilling, anti-sticking, automatic shutdown, automatic withdrawal, rig and drilling Automatic arm shifting, positioning and remote control operation system, etc. The fully automated Underground jambo is called a rock drilling robot. Because this kind of rock drilling robot is mainly used for tunnel excavation, it is also called a tunnel rock drilling robot.
The development trend of environmental protection of Underground jambos: To reduce noise, protect the health of operators and improve the working environment, hydraulic Underground jambos are generally used. This is because the hydraulic Underground jambo has low noise and will not emit oil mist and harmful gases. Compared with pneumatic Underground jambos, hydraulic Underground jambos also have the advantages of low power consumption, high energy interest rate, high drilling efficiency, and no exhaust noise.
It is the responsibility of each manufacturer to produce an Underground jambo that meets the standards, to ensure the safety of the electricity supply and the healthy development of the cable market. Hambition Drivetrain Components & Parts Co., Ltd conducts many tests on Underground jambos for connection before they leave the factory, and the quality qualification rate is guaranteed. If you are in the Underground jambo business, you can consider our cost-effective products.
