Development Background In the rescue construction of water conservancy projects, riprap rock and solid foundation is one of the most common governance measures to be carried out each year. According to statistics, from 1998 to 1999, 4.3.10 million cubic meters of stone were thrown from the hidden levee project of the Yangtze River. In the Jiaozuo reach of the Yellow River, it is necessary to add 4 to 60,000 cubic meters of reinforcing stones every year to be able to change passive rescue into active rescue. However, the currently used manual assembly and small-scale machinery and equipment methods have not been able to meet the needs of large quantities of low-level work. They also have the problems of high risk, low work efficiency, high labor intensity, and serious damage to Tanzanian slopes. Therefore, as soon as possible, the research and development of high-efficiency large-scale mechanical rock throwing equipment will play a decisive role in the management of hydraulic engineering and reinforcement of dikes.
Flood control stone throwing machine (as shown above) is a new type of practical flood prevention and rescue stone thrower developed for the above problems. The application of the aircraft will greatly increase the efficiency of rescue operations, protect Tanpo, and meet the needs of water conservancy projects.
The large-scale flood-prevention and rescue stone throwing machine consists of four mechanisms: rock dumping, hydraulics, walking, and missile rock. It mainly consists of a stone thrower walking system, a stone throwing length adjustment system, a riprap slope adjustment system, and a throwing angle adjustment. Most of the system, buffer system, etc.
Walking system. By using a wheel-type walking mechanism, by adjusting the direction of the tire axle, both longitudinal movement and short-distance movement along the Tanzanian slope can be achieved. Longitudinal movement can be self-moving, but also can be dragged by the loader to move; self-propelled walking mechanism to rely on hydraulic motors to drive the tire rotation to walk.
Cast stone row length adjustment system. The riprap shelving is designed as a two-section retractable mechanism. The length of the riprap row can be adjusted through hydraulic cylinder expansion and contraction.
Stone dumping slope adjustment system. According to the slope of Tanpo, the height of the riprap row leg is adjusted by the hydraulic cylinder expansion and contraction, so as to adjust the slope of the riprap row.
Shock absorption system. Comprehensive comparison of various buffering measures such as springs, rubbers, etc., using the best structural form, to minimize the impact force when the loader unloads and improve the service life of the stone thrower. In addition, the stone throwing machine can realize the real-time adjustment of the ejection angle and achieve the purpose of positioning the stone once and accurately.
Technical Specifications Large-scale Flood Prevention and Dumping Stone-throwing Machine Technical Index: Single throwing stone capacity 2.5-3.0 cubic meters, per hour stone throwing capacity 100-150 cubic meters, applicable Tan slope gradient 1:1 to 1:2, maximum stone throwing distance 10 m, lateral movement speed 5 to 10 meters/minute.
The aircraft has the following characteristics: it is flexible and flexible, it can not only move along the road from a long distance, but also can be moved along the short slope of the Tanzanian slope. It is easy to use and practical, and can adjust the slope of the rock dump in real time according to the slope and length of the Tanzanian slope. And length; efficient operation, compared with artificial riprap, can increase productivity 200 to 250 times.
The successful development of a large-scale flood prevention and rescue stone throwing machine will change the current situation of low mechanization of flood prevention and rescue, and make the management of water conservancy projects a big step toward mechanization and modernization. At the same time, it has also increased the efficiency of rock dumping operations, enhanced the capacity for flood prevention and rescue, protected state property from losses, and has significant economic and social benefits.
At present, the project has completed the design of technical lines and drawings, and has now entered the prototyping stage.
