Is there anyone who doesn't know the difference between a rock dr

What is the difference between a rock drill and a rock drill jumbo? Some people say that the rock drill is a component and the rock drill jumbo is a complete machine; It is also said that the rock drill can directly mine stones, and the rock drill jumbo is a commonly used drilling equipment for tunnels and underground projects. What's the difference between them? Let's compare.

1、 Working ability

The rock drill uses the impact energy to break the target material. When working, the piston repeatedly impacts the drill bit tail with high frequency. The drill bit tail transmits the impact energy to the drill bit, crushing the rock and drilling into a certain depth.

Each time the drill bit is pulled back and punched out, the drill bit rotates at a certain angle, and the two adjacent impact positions are connected to form a sector shaped dent, which is then shattered and forms a round hole after several times.

The rock drilling jumbo is used to install one or more rock drills on a specially made drill arm or drill frame, and is equipped with a frame and other necessary auxiliary equipment, which can be used for drilling, charging, supporting, measuring and other functions.

2、 How to use

The staff of the rock drill shall wear goggles, and one or two persons jointly operate the equipment manually.

The drilling jumbo is operated remotely by workers. The driving force generated by the thruster controls the advance or retreat of the equipment, and can also give a certain axial thrust when the rock drill is working; The drill arm supports the rock drill. The drill arm can be lifted and swung horizontally and transported to any position for drilling.

3、 Scope of use

In addition to drilling holes during mining, the rock drill can also be used for building construction, cement pavement, asphalt pavement splitting, crushing, tamping, shoveling, etc. Basically, any scene that can be used for drilling and blasting construction can be used.

As a large machine, rock drilling jumbo is mainly used for rock drilling in tunnels and underground projects, such as Class III, IV and some Class V surrounding rock sections of Class I and II highways, expressways and railway super large tunnels.

4、 Practical operation

1. Drilling speed

The speed of the rock drill jumbo is much faster than that of the rock drill. The rock drill is driven by manpower. The rock drill jumbo can be pushed through multiple holes at the same time, forming holes at one time, saving time. The equipment is positioned accurately, and it is convenient to rise and fall. No auxiliary platform is needed.

2. Basic functions

The drilling jumbo is equipped with detection equipment, which can detect the geology within the range of 5-30m and achieve advanced exploratory hole construction. The rock drill can only judge the surrounding geology by workers' experience.

3. Construction safety

The drilling jumbo can basically realize automatic construction, requiring less personnel. The operator can control drilling under the protective ceiling, with higher safety performance. In addition, the drilling jumbo can also be equipped with a sound insulation room to further optimize the working environment of the staff.

4. Construction quality

The drilling of the drilling jumbo is positioned by the equipment, and the advancing angle is fixed. The amount of over excavation is small, and the half hole is well formed. The drilling quality is higher than that of the manually used drill.

5. Equipment input

As a large mechanical equipment, each rock drilling jumbo is expensive, with a purchase cost of millions. If it is imported from abroad, the spare parts also need to be imported from abroad, with a high cost investment, while the cost of hand-held rock drill is only thousands. Therefore, if the working tunnel is short, there is no need to use the drilling jumbo. Generally, only the tunnel above 2500m can purchase the drilling jumbo.

To sum up, it is the difference between a rock drill and a rock drill jumbo. Although there are many advantages of a rock drill jumbo, if your construction volume is small, don't consider it. For projects with small sections, short tunnels, and frequent geological changes, hand-held rock drills have more advantages.
