Function:
QJS-50L multi-function drilling rig is equipped with large-diameter through-hole power head, heighten vice tower and superimposed double crane hoisting. It adopts load-sensitive variable hydraulic system. Through innovative electronic control technology, it realizes the function of clamping large-diameter drill rod long-distance fine-tuning step construction. It is especially suitable for double high-pressure RJP construction method and multi-tube MJS ultra-high-pressure jet grouting construction method.
Technical parameters:
Model QJS-50L A joint pipe（max)(mm) 15 Chuck diameter(mm) Φ145 Output torque(N.m) 8000 Output rotary speed(r/min) 0~45、0~90 Power head stroke(mm) 4000 Lifting force of power head (kN) 85 Power head plus pressure(kN) 50 Power head lifting speed(m/min) 0-6.1 Power head pressure velocity(m/min) 0-10.3 Holding range(mm) 60-220 Construction form(L×W×Hmm) 6200×3300×17800 Transport status shape(L×W×Hmm) 7600×3000×3000 Weight(kg) 16000 Input total power(kW) 45+15
Advantage:
1. The maximum through-hole of the through-hole power head reaches Φ145mm, which can clamp RJP and MJS drill rods to realize large diameter and ultra-high pressure jet grouting operation.
2. The crane hoisting with effective height over 16m can realize long-distance construction to the end without frequent dismantling of drill rods, which greatly improves work efficiency and overcomes the shortcomings of traditional RJP and MJS methods such as long auxiliary working time and low efficiency.
3. Crawler chassis with automatic slewing support is easy to displace and orifice, which further reduces the auxiliary working time and improves the construction efficiency.
4 During the operation of RJP and MJS, through the flow control of hardening material (cement slurry) and the monitoring and control of a series of processes such as pressure conveying, jet cutting and forced sludge discharge, large diameter piles and precise foundation reinforcement can be realized, which has little influence on the surrounding environment and foundation disturbance, and the mud returned from the stratum can be centralized managed with little impact on the environment.
Features:
1. The maximum output torque of the through-hole power head is 6000Nm, which has two speed ranges of 0-30rpm and 0-60rpm. Compared with the same type of machine, the rotate speed range is wider, and it has more adaptability in construction technology.
2. The maximum travel of the power head is 4000mm and the maximum pull-out force is 10T. Compared with the effective drilling of the same type, the drilling process is longer and the pull-out capacity is larger, which can meet the construction requirements of deeper hole-forming and pile-forming.
3. The drilling rig is equipped with a crawler chassis with a two-speed walking motor, and connected with the main machine with an automatic slewing supporting, so that the drilling operation is fast and convenient.
4. The front leg of the drilling rig adopts the forward extension structure. During the construction, the fulcrum of the drilling rig extends forward, the support force of the hole center is more concentrated, the construction and up and down drilling are more stable.
5. The drilling rig is equipped with integrated cab, with cold and warm air conditioning, monitoring display screen and operation input panel integrated in the cab, which improves the operation environment and instrument protection.
