The tamping machine is a kind of professional equipment for loosening the soil compaction, its working principle is to hoisting machinery hammer raised to a certain height, free fall to the ground soil with strong energy tamping, forcing the soil a sticky re arranged, so as to improve the soil strength, reduce the compressibility.
With a large number of domestic chemical industry, port, airport construction projects, of tamping equipment increasingly strong demand. But at present, the domestic and foreign markets for the crawler crane is suitable for dynamic compaction process improvement "substitute the tamping machine". The three one group starting from the market, independent research and development of the world's first non decoupling cylinder tamping machine "Conqueror" SQH401, the first to fill the "professional strong tamping machine" gap in the market, become the strong tamping machine field of epoch-making product. This product is a new type according to the research for many years on the dynamic compaction construction method to the independent research and development, and it merges the advantages Sanyiduo level crane, and also absorbs the domestic and foreign advanced technology, product performance and strength.
Industry pioneer cylinder lifting technology "Conqueror" to the concept of product design innovation, in the strong tamping machine field, completely abandon the traditional hoisting technology, pioneered the use of cylinder with independent intellectual property rights, promote technology, can provide the 240t strong power, to ensure that in the high speed (15m/s), high voltage (35MPa) to use the demand, make the tamping energy utilization efficiency compared with traditional motor speed reducer 15% improvement; at the same time, the lifting cylinder has passed 200000 enhancement test, cumulative run up to 2000Km. On the other hand, cylinder lifting technology effectively circumvent the hoist rope disorder problem, reduce the service life of wire rope wear, compared to the traditional ways to improve 5 times, from the original 4000 sharply increased to 20000 times.
The industry original non continual upgrading of decoupling technology in the industry of original non decoupling technique based on 400t/m, single cycle time is 40s, 2 times the work efficiency to the industry average, 800t/m (with a door frame) can reach to 3 times. At the same time, high efficiency and stability of continuous tamping, without manual hook; it can be applied to more complex conditions, meet the pit of dynamic compaction, solve the problem of inconvenient hook, can be extended to the dynamic compaction construction condition under water. The machine adopts the large power 251Kw engine, ensure to provide a powerful impetus to the demand.
Special chassis and supporting system with high stability and strong high stability mature tamping special chassis and supporting system, lower maintenance cost, expansion ratio 1:1.45, fully meet the dynamic consolidation and transportation demand; increase the slewing bearing, slewing bearing by 90 tons, to further improve the stability of the whole machine. Arm frame with high strength materials, through the CAE optimization design, set aside enough safety margin, enough to adapt to the dynamic compaction construction conditions. Boom has been through the machine 200000 times of fatigue test, the service life is "alternative strong tamping machine" longer.
Intelligent technology in intelligent technology application domain, "Conqueror" set the industry's top innovation technology in one, the first use of intelligent control systems and intelligent construction management system.
The control aspect, realizes intelligent control technology of flexible lifting height, real-time display of tamping depth, and a key to achieve automatic cycle tamping; record and output fully black box function, measurement data, to realize real-time monitoring of real-time working status and parameters, solves the problem that the traditional compacting artificial measurement inefficient process, greatly enhance the strong compaction quality and efficiency. At the same time, 150 meters long distance remote control operation, make the operation more safety, more relaxed. In addition, the control system of the vehicle also has 11 kinds of protection and more than 30 kinds of fault self diagnosis function, guarantees the machine operation more safety, while reducing the machine failure rate and machine maintenance cost, reduce the machine failure downtime.
In the development process of the dynamic compaction machine, develops many times three one with customer technical exchange meeting, the scene to listen to our customers and product rectification, also invite domestic and foreign well-known dynamic compaction construction units of the leadership and experts, the scene to watch the strong rammer construction test and guidance. Products to the market, the maximum to meet customer demand.
Analysis shows, 2014 domestic tamping market may be in 7000000000 yuan, three one SQH401 tamping machine driv.
