The crawler hydraulic drilling rig refers to a full hydraulic rock drilling and drilling machine with a crawler traveling mechanism.
The crawler hydraulic drilling rig is composed of a power unit and a hydraulic system, a crawler traveling mechanism, a drill frame equipped with a hydraulic rock drill and a propeller, a support arm, and a drill rod unloading device. The drilling hole diameter is 35 ~ 125mm, and the drilling depth can reach 30m, which is suitable for large-scale stone excavation and drilling operations. Except for high-pressure air or water used for drilling and drilling, all other operations are hydraulic.
Crawler Mounted Hydraulic DTH Drilling Rig
Compared with the pneumatic monk rock drill (air drill), the crawler hydraulic drill has the advantages of low power consumption, high rock drilling speed, low noise, and improved working conditions.
Hydraulic crawler drills are the stereotyped products of hydraulic rock drills, which are characterized by:
(1) The rig can swing, telescope, and swivel, has mobility to adapt to the operating environment, and can shorten the preparation time for the operation.
(2) The front end of the working cylinder is equipped with a two-way hydraulic locking device to ensure safety and stability.
(3) The tracked walking mechanism adopts a separate pressurized driving device, and is equipped with a hydraulic jack support device, which can turn in place and can adapt to uneven ground operations.

(5) Equipped with drill pipe unloading device, equipped with 5 ~ 7 drill pipes, which can be used to quickly complete the operations of connecting, disassembling, centering, entering and exiting the drill pipe, etc., which saves time and reduces physical labor.
Pneumatic drilling rig for mining: High-efficiency drilling rig with simple operation in coal mine. Crawler-type pneumatic drilling rig is a compressed air powered drilling rig for walking and drilling. Although it sounds complicated, it is simple to operate. One row of operating tables, 6 operating levers, forward and backward, turn, adjust the angle of the drilling position, and drill out Get it all.
The drilling operation and walking of the crawler pneumatic drill are controlled by an independent console. For drilling operations, first stabilize the rig and turn the start-stop button of the rig console to the stop position, and then pull the rear-end ball valve on the pumping station to get the rig's pneumatic console. There are two reversing valves on the console to control the rotation and advancement of the rig, and a ball valve to control the amount of water in the drilling process. The right control valve controls the rotation of the rig. It pushes the host forward and pulls backward to reverse. The middle position stops. The left control valve controls the forward and backward movement of the gyrator, pushes the gyrator forward, pulls the gyrator backward, and stops in the middle position.
This type of coal mine underground crawler-type pneumatic drilling rig can be used in connection with high-pressure air outlets, no motor, no electricity, no explosion danger, high safety. Pneumatic crawler drilling rigs can be operated across belts and scrapers, and are suitable for drilling underground holes such as water holes, gas holes, pressure relief and punching.
The Crawler Mounted Drill Rig is a dual-purpose drilling rig suitable for high-pressure rotary jetting and anchoring construction technology according to market needs. It is easy to move and move, reducing the labor intensity of construction workers. At the same time, due to the installation of the crawler chassis, the moving speed during the drilling process can be greatly improved, thereby effectively improving work efficiency.
The Crawler Mounted Drilling Rigs can be configured according to different performances. The maximum output torque of the rotary drilling rig can reach N.m, and the maximum pulling force can reach 60kN. The hole can be selected from the rotary drill of the hard alloy drill bit and the impact hammer of the down-the-hole hammer. Drilling and other processes, so that it can be directly formed into holes in the majority of the formation, and immediately sprayed into piles.
What is a jet grouting pile?
The jet grouting pile is to use the rotary jet drilling machine to place the rotary jet grouting pipe and the nozzle drill in the design height of the pile bottom, and the pre-formed slurry is passed through the high-pressure generating device to obtain a huge energy of the liquid flow, and then from the nozzle of the grouting pipe side. High-speed injection, forming a highly concentrated liquid flow, directly destroying the soil. During the spraying process, the drill pipe is rotated while lifting, so that the slurry and the soil are fully stirred and mixed to form a columnar solid body of a certain diameter in the soil. So that the foundation is reinforced. The construction is generally divided into two work processes, namely, first drilling and then spraying, then drilling down, and then lifting the mixing to ensure the proportion and quality of the slurry per meter.
