The shotcrete sprayer is a concrete spraying machine unit that integrates spraying and feeding. It is mainly used in engineering construction in the fields of railway highway tunnels, water conservancy, and hydropower, subways, mine roadways, military installations, various underground construction, and emergency rescue. The basic process is to use hydraulic pressure to transport the pre-mixed concrete to the spray gun through the pipeline, connect compressed air and quick setting agent to the spray gun, and then spray the concrete to the spray surface at high speed to form the concrete support after rapid setting and hardening floor. With the large-scale development of modern engineering construction, the market demand for shotcrete trucks has rapidly expanded in recent years, and the requirements for construction efficiency have become higher and higher. The construction efficiency is not only reflected in the process of spraying, but also in the flexibility of the product.
The hydraulic automatic feeding unit for shotcrete is a new product developed by our company according to the needs of national infrastructure construction. This product can be used for two shotcrete machines at the same time. This product can be widely used in the construction of large-span tunnels. It has the characteristics of high efficiency and humanization. It replaces the traditional manual feeding construction mode, saves the labor to the greatest extent, avoids the harm of construction workers caused by manual feeding dust, and avoids it avoids the waste caused by the material residue on the unhardened working surface when loading manually. This product has a number of national patents, advanced technology, perfect functions, simple operation, easy maintenance, no wearing parts, and can minimize the construction cost.
The auto-feeding shotcrete truck must be driven and operated by strictly trained professionals; drivers should keep the keys carefully, and non-professionals are strictly prohibited to drive and operate this equipment.
During the driving of the spraying vehicle, there is a command from the front and back of the vehicle, and no one except the driver can take the vehicle during the traveling process.
The sprayer must select experienced and skilled workers and perform the spraying operation outside the safe range.
Before the vehicle moves, the silo and accelerating agent hopper must be emptied, and the silo should be put in place on the silo frame.
It is strictly forbidden to move the automatic feeding gun before the lifting cylinder of the silo is fully retracted.
The vehicle must be disconnected from the external power supply and air source before moving.
After stopping the engine, the handbrake parking device should be pulled up to prevent the car from causing accidents; after releasing the support legs, make sure that the equipment is in a horizontal state and will not tilt or fall.
Check carefully before starting the equipment to ensure that there are no exposed wires, aging, leakage, short circuit, etc. to eliminate potential safety hazards.
Other personnel must return to a safe area before starting the equipment. It is strictly forbidden to stay, climb or stand beside the equipment, and it is strictly forbidden to stand under the hopper.
The operator must wear safety protection equipment before operating the equipment.
It is strictly forbidden to touch the operation device with limbs or tools when the equipment is in operation.
When pipe blockage occurs, it must be shut down in time to cut off the wind source and power supply to prevent pipe explosion.
