​Application of Underground jambo

Views: 0     Author: Site Editor     Publish Time: 2021-12-09      Origin: Site Inquire

Rock Underground jambo (also known as Underground jambo) is a kind of rock Underground jambo equipment used in tunnel and underground engineering. It can move and support multiple Underground jambo machines simultaneously. The working mechanism is mainly composed of a propeller, the drill arm, the rotary mechanism, and the translation mechanism. Rock Underground jambos can be divided into drift Underground jambos, mining trolleys, rock anchoring trolleys, and open-pit Underground jambos. According to the walking mechanism of the drill car, it can be divided into rail wheel, tire, and crawler type. According to the number of set up, Underground jambo machines can be divided into single machines, double machines, and multi-machine drill cars. The following is an introduction to Underground jambo.

The working organization of the rock Underground jambo

The working mechanism is mainly composed of a propeller, the Underground jambo arm, the rotary mechanism, and the translation mechanism. The main thrusters are steel rope piston type, wind motor piston type, and pneumatic spiral pair type. The function of the propeller is to enable the drill to move rapidly towards (or away from) the working face in preparation for opening and to provide a certain axial thrust to the drill while drilling. The operation of the propeller should be reversible. The axial thrust and thrust velocity generated by the Underground jambo shall be adjustable to allow the drill to operate under optimal axial thrust conditions. The drill arm is the working arm that supports the rock drill. The structure and size of the drill arm, the flexibility, and the reliability of the Underground jambo arm action will affect the application range of the drill car and its production capacity.

The slewing mechanism of the Underground jambo

The Underground jambo can be divided into swing rotary column, spiral pair rotary column, polar coordinate drill arm rotary mechanism. The structure of the swinging rotating column is characterized by a rotatable rotating sleeve 2 outside the rotating column shaft 3. The lower end of the Underground jambo arm and the lower hinge of the oil cylinder of the support arm is hinged on the rotating sleeve respectively. When the swing arm cylinder 1 is telescopic, the rotating sleeve rotates around the axis, thus driving the Underground jambo arm to swing from side to side. The swinging rotary column has the advantages of simple structure, reliable operation, and convenient maintenance. The translational mechanism of the propeller is commonly used in the underground jam, there are two categories of mechanical translation mechanism and hydraulic translation mechanism. Belongs to the mechanical translation mechanism are shear type, plane four-link type, and space four-link type, and so on; It belongs to the hydraulic translation mechanism with or without translation guide cylinder type and with translation guide cylinder type.


Classification of rock Underground jambos

The Underground jambo walking mechanism has a track, track, and spoke type, excavating type four. The rail carriage body is generally gantry type, so it is often called gantry type Underground jambo. Its upper part has 2 ~ 3 layers of the working platform, can be installed more than (up to 21) drills; The lower part can be loaded with ballast machines, transport vehicles, and other machinery and tools. The trolley has many functions such as drilling, charging, supporting, and measuring. It is developed to meet the needs of large section tunnel construction and overcome the shortcomings of the low Underground jambo of the hand-held rock drill. It is popularized and applied in the construction of railway tunnels and hydraulic tunnels.



It is the responsibility of each manufacturer to produce an Underground jambo that meets the standards Hambition Drivetrain Components & Parts Co., Ltd. conducts many tests on Underground jambo 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.
