Do you know Crawler Hydraulic Rigs?

Definition

A crawler hydraulic drilling rig is a fully hydraulic rock drilling rig with a crawler travel mechanism. Crawler hydraulic drilling rigs consist of a power unit and hydraulic system, a crawler travel mechanism, a drilling frame with hydraulic rock drills and augers, a jib, and a drill pipe unloading device.

With competitive price and timely delivery, JK Drilling sincerely hope to be your supplier and partner.

Advantages

The crawler-type hydraulic rock drill has the advantages of low power consumption, fast rock drilling speed, low noise, and improved labor conditions compared to the pneumatic and monk rock drills (air drills).

Structure

The crawler-type hydraulic drilling rig consists of a power unit and hydraulic system, a crawler walking mechanism, a drilling frame equipped with a hydraulic rock drill and auger, a support arm, and a drilling rod unloading device. With a drilling hole diameter of 35 to 125 mm and a drilling depth of up to 30 m, it is suitable for large stone excavation and drilling operations. All operations are hydraulic except for the high-pressure air or water used for drilling and boreholes.

Features

1. The crawler travel mechanism is independently pressurized and driven and is equipped with a hydraulic jack support device, which allows it to swivel in place and adapt to uneven ground operations.

2. The front end of the working cylinder is equipped with a two-way hydraulic locking device to ensure safety and stability.

3. Equipped with a drill pipe unloading device, equipped with 5 to 7 drill pipes, it can quickly complete the operation of connecting, dismantling, aligning and entering, and leaving the drill pipes, saving time and reducing physical labor.

4. The drill rig can swing, telescope, and swivel, with mobility to adapt to the operating environment and shorten the preparation time for work.

Applications

Pneumatic drilling rigs for mining: simple and efficient drilling rigs for operation in coal mines. The crawler pneumatic drilling rig is a compressed air-powered drilling rig for walking and drilling. Although it may sound complex, it is simple to operate. A row of consoles, 6 operating levers: forward, backward, rotate, adjust the drilling position and angle, and drill with one key.

This type of underground coal mine crawler pneumatic drilling rig can be connected to a high-pressure outlet for use without a motor, without electricity, without risk of explosion, and with high safety. The pneumatic crawler drilling rig can work across belts and scrapers and is suitable for underground drilling of water holes, air holes, pressure relief, and punching holes.

The drilling operation and the travel of the crawler air drill are controlled by a separate console.

For drilling operations, the rig is first stabilized by turning the start/stop button on the rig console to the stop position and then pulling the rear end ball valve on the pump station to obtain the rig's pneumatic console. The console has two reversing valves to control the rotation and advance of the rig and a ball valve to control the amount of water used during drilling. The right control valve controls the rotation of the rig. It pushes the main engine forward and pulls backward to reverse the rotation. The middle position stops. The left control valve controls the forward and backward movement of the rotary, pushing the rotary forward and pulling it back to stop in the middle position.

The crawler pneumatic drill rig is a kind of light walking crawler with deep hole drilling rig powered by compressed air. It is suitable for the construction of water exploration, gas exploration and gas drainage holes in underground coal mines. The crawler pneumatic drill rig uses compressed air as the power source, which is safe and convenient for it to walk. In addition, what other advantages are worth using in the mine?

1. The track of the crawler pneumatic drill rig can rotate automatically, and the drilling range is 360° horizontally and 360° vertically.

2. The crawler pneumatic drill rig can reach out of the car body for drilling, and it is easy to cross the belt support machine and other coal mine working devices for the drilling operation.

3. With its small external size, it can walk freely in a 0.8-meter tunnel. The high-power walking system is equipped with a vehicle-mounted drill pipe space. The feed of the drilling rig adopts an independent motor, so the feed speed is easy to control.

4. This type of industrial drilling equipment has a structure of the muffler that minimizes noise, which can effectively improve your working environment. The crawler pneumatic drill rig has a split structure for supporting the column to facilitate underground transportation through the air gate. The whole machine is equipped with a large-capacity oil mist device, thus it can be used for a long time once being filled up.

5. The crawler pneumatic drill rig is equipped with different drilling tools to realize the construction of exploration and relief holes, and the matching large-diameter drill bit has an obvious effect on drilling pressure relief holes. it pioneers in its drilling diameter, drilling depth, etc. In the drilling construction of any soft and hard medium, the bit cutting terminal always maintains a power output of more than 20kW and is more efficient than the similar products in the market.
