Crawler Type Rock Tunnel Digging Rig

Hydraulic drifter, brand Montabert

The hydraulic drifter has better reliability and performance, and its efficiency is more than 2-4 times of that of the pneumatic type; the hydraulic offset system can prevent the empty drilling under the wrong operation and protect the drifter; the special structure design of the fiber tail can eliminate the reaction force during impact, play the role of anti strike protection, and prolong the service life of the drifter.

Large climbing capacity type (≤ 28 °)

In the mining and diversion tunnel excavation, the steep slope has always been the bottleneck in the construction. Our company specially develops this large climbing capacity crawler type Drilling Rig for large angle slope, which can greatly reduce the workload.

Translational boom

The mechanical fully translational drill arm has the function of keeping the propulsion beam parallel in all directions, which can be directly, quickly and accurately positioned; the drilling holes are relatively parallel without manual calibration, and the operation is simple, and the distance precision and parallelism between holes can be well controlled.

The boom adopts a square beam section design, which makes the overall stress of the boom more stable. The rotary motor at the front end of the boom can make the whole propulsion mechanism rotate ± 180 ° and move flexibly.

The self-developed special propulsion sliding frame has been cold drawn and calibrated for many times. It has the characteristics of high bending strength, torsional strength, compact structure and light weight.

Well-known brand hydraulic drifter, with high drilling hardness, high drilling speed, low drill tool consumption and low failure rate. Imported screw oil cylinder, high torque, high bearing capacity, no position offset, super compact, good anti pollution ability and durable.

Hydraulic system

The drilling control system with direct operation and manual four-way handle are used to control the horizontal movement of the boom. The anti sticking function and step-by-step pressurization system are provided to make the work more stable and reduce the fiber consumption.

The design of upper oil tank and pump in low position can effectively avoid the fault of "no negative pressure in the oil tank, which leads to the oil pump can not absorb oil, and the oil pump cavitation for a long time".

The cross steering joint is formed by the combination of hydraulic turbine reducer and screw oil cylinder, which can drill holes at any angle of face, top, side and bottom without dead angle.

Multiple filtration system can effectively ensure the cleanliness of oil and reduce the fault of hydraulic system;

Reasonable pump flow matching and efficient water cooler ensure that the system can still maintain a good oil temperature after a long time of operation.

This YKU-C25 Crawler Type Rock Tunneling Project Rig, also named rock mining drilling jumbo, is mainly applicable for blasting hole and bolt hole operation in the field of coal mine and metal mine driving. Workers stand in a safe place to operate the mechanical arm to drill rock. This equipment replaces the previous manual hand-held air gun drilling operation, reducing the work intensity of workers, improving work efficiency and safety factor. It is suitable for sections (width x height) from 3.0m x 3.0m to 5.9mx4.3m. The walking speed can reach 2.4 km / h when the slope is less than 14 degrees. The working mechanism of the machine adopts full hydraulic drive, and the drilling speed can reach 0.8-2m/min. The working mechanism of the machine adopts full hydraulic drive, which is flexible and fast in rock drilling. The hydraulic system is advanced and easy to maintain. It has stable operation, strong climbing ability, convenient operation, safe and reliable.
