A. Front and rear leg the span is large, work stability.
1.The front leg
Adopts horizontal telescopic cylinder + H-type legs, legs span is large, according to the construction site, respectively, control the length of the leg can effectively increase the stability and safety of the equipment.
2.The rear leg
Adopts eight characters closed type leg, forcing ability is good, more stability, can effectively support the rear hopper pumping concrete cylinder loading impact.
B. Pumping system
1.pumping system using φ160 concrete cylinder, 1.2m stroke, the main cylinder cylinder diameter φ100. (30 trolley)
2. pumping hydraulic system using 55KW four-pole motor 130ml / r adjustable displacement of the main pump + 45ml / r
Variable pump (Rexroth series)
3.The main valve adopts the eight-line proportional valve (BARMAG), which has the variable variable switching function. When switching to the variable mode, the electric proportional valve can load-sensitive the variable pump according to the current action and load, Guide the variable pump output variable, so that achieve the purpose of energy efficiency.
1. long stroke, less times of commutation,small transport impact, less volatility, the jet surface is clean , smooth, easy to control.
2.130ml / r adjustable displacement of the main pump, low energy consumption, high reliability, long life, adequate displacement.
3.45ml / r variable pump, according to the action speed and amplitude of the size of the output displacement, reduce energy consumption, action coordination and stability.
4.less switching times, make glasses plate, cutting loop changing cycle long time. Export pressure, transport material ability is strong, do not pick material, blocking the risk is greatly reduced.
C.The boom adopts symmetrically arranged structure
Advantages:The boom is symmetrically arranged with a symmetrical structure. The telescopic arm is connected to the base arm on the same axis. The telescopic arm is directly connected to the base arm through the pin. No connecting arm, no lateral force, no stress concentration, no happen Fatigue cracking, so the boom system is more stable and reliable.
the boom swing the wings by swing motor connecting, then fly arm connect the jetting mechanism, can swing ± 45 °.
Advantages: Swing arm swing angle is big, strong stability, can increase the flexibility of the jet mechanism to improve the single sprayable area, not only the spray surface is more smooth, beautiful, but also reduce the turntable rotation times, increase the stability of the boom
Telescopic arm with four BS700 high-strength steel plate welded after welding, weld joints have a lap bar, arm overall stiffness increase
Advantages: high-strength steel of the boom make the telescopic arm in the wet spray operation state, the jitter amplitude is small, good stability, can improve the quality of the spray surface
F.Reinforced rotary drive mechanism
1.rotary reducer adopts turbo-type gear reduction mechanism, big reduction ratio, strong self-locking ability, the big output torque, stable smooth operation, high reliability.
2.rotary ring gear is big, roller diameter is 760mm, tooth surface after quenching, chrome and other post-processing technology, high strength, not prone to tooth phenomenon.
3.Adopts well-known brand rotary motor, large displacement, torque, good stability, in the precise control of the proportional valve, the rotation without jitter phenomenon.
G.Electrical control system
