​Advantages of Underground jambos

Views: 0     Author: Site Editor     Publish Time: 2021-12-07      Origin: Site Inquire

An Underground jambo is a device that installs one or several rock drills together with propellers on a special drill boom and is equipped with a chassis to perform rock drilling operations. It is a modern construction machine developed on a hand-held rock drill and a trailer-type chassis base vehicle. Reasonable application of Underground jambos is an important way to increase mining speed. Next, I will introduce you to the Underground jambo.

What is the working principle of the Underground jambo?

Underground jambos are also called drilling rigs. It is a kind of rock drilling equipment used for tunnel and underground engineering construction by drilling and blasting method. The Underground jambo can move and support multiple rock drills to perform drilling operations at the same time. The rock drill rig is mainly composed of a rock drill, a drilling boom, a steel frame, a running mechanism, and other necessary auxiliary equipment, as well as equipment added according to the needs of the project. When the drilling and blasting method is used to excavate tunnels, it provides favorable conditions for the use of Underground jambos. The combination of Underground jambos and ballast loading equipment can speed up construction, increase labor productivity, and improve working conditions.

What breakdowns are prone to Underground jambos?

1. The new car cannot be located

When the new Underground jambo is just in place, the boom end jack leg control adopts the horizontal and vertical linkage at the left end and the horizontal and vertical linkage at the right end. The linked outrigger cylinders are extended and retracted at the same time. When positioning in this way, when the longitudinal outriggers touch the ground, the system pressure oil is released through the safety valve and returned to the oil, and the positioning operation is forced to stop.


2. The sensitivity of the safety valve is not high, causing malfunctions

If the operating sequence of the drill boom end of the Underground jambo is wrong, because the safety valve on which the positioning system is based is not sensitive, it will cause the positioning pressure to increase sharply, and failures such as "positioning pipe bursts and oil leakage" at the initial stage of use will occur. It is a waste and delays tunnel operation time.


3. Failure caused by misoperation

The positioning pump of the Underground jambo stopped working in time, but the positioning system is still under pressure. If the control handle is touched or operated by mistake, it may cause malfunctions and even cause accidents.


4. Failure caused by imperfect pressure oil filter system

Because the principle of the pressure oil filter system of the Underground jambo is that when the filter is blocked, the pressure oil does not return to the oil tank, but continues to enter the system. In this way, it is easy to cause the system of the Underground jambo to lose control. This is the reason for the out-of-control of the propulsion cylinder that often occurs in the initial stage of use. Improving the pressure oil circuit filtering system can reduce system out-of-control failures.


What are the advantages of Underground jambos?

The Underground jambo has the advantages of a small body, compact structure, low center of gravity, maneuverability, stable work, and strong climbing ability. The Underground jambo adopts crawler walking mode and can work on 28° ramps. Drilling operations use electric work to greatly improve the working environment, reduce noise, reduce dust, reduce energy consumption, and greatly improve construction efficiency and construction quality. The flexible hydraulic rock drilling mechanism can drill the working face, roof, side, and bottom of the harbor. Underground jambos can not only drill and drill blast holes but also drill bolt holes conveniently according to the size of the section.


Today,Hambition Drivetrain Components & Parts Co., Ltd has been well developed. And the intelligence of Underground jambos is very high, and gradually tends to the unification of international standards. Therefore, different vehicles can integrate different Underground jambos from different suppliers. Whether it is a simple Underground jambo or an intelligent Underground jambo. Fiber Underground jambo is an ideal choice.
