Combination of advanced design concept and lean R & D process: CM350 crawler rammer
Liugong CM350 track rammer is one of the star products of Liugong. How much do you know about it? Today, Xiao Bian will carefully introduce this machine for you.
Combination of advanced design concept and lean R & D process: CM350 crawler rammer
The product is Anhui Liugong combined with years of experience in the development of crawler crane, based on full understanding of customer needs and dynamic construction conditions, will be the most advanced design concept (Design for six sigma DFSS) into the research and development process of Liu Gongxin products (LDP), the use of a full hydraulic crawler professional 3D design software CREO ANSYS and ADMAS finite element analysis software of PLM and SAP in the collaborative work system and design of dynamic compaction machine.
In the process of product design, 16 new technologies and new structures were adopted. At present, 16 patents were applied, including 7 patents. The test and the use of customer satisfaction that products not only in the overall stability, customers are most concerned about the lifting capacity, efficiency and reliability, the use of wire rope work life, driving performance and safety of the key performance indicators in the domestic leading position, and in the self assembling, appearance, integrated device, decoupling maintainability and a large volume of fuel tank or other properties of the structure is also in the domestic leading position.
Ten major technical highlights
High stability
The design concept is to move the focus of design, through the reasonable layout of the center of gravity, and improve the turntable and lengthened off frame rigidity, with angle steel arm frame, rigid good use clearance adjustment mechanism, special two damper backstop and rigid luffing pull plate etc., realize the dynamic compaction in the construction of high stability.
High reliability
The hydraulic system is equipped with an independent power dissipation system, into the return pipe diameter, hydraulic tank volume is up to 600L, completely avoids the phenomenon of high temperature caused by the long time work, and fully guarantee the reliability of the hydraulic system of continuous operation; based on the level of heavy machine in the track up greatly, with quick release winch system level M7, fully meet the requirements of working conditions for frequent work, high strength, large vibration load and poor working environment of dynamic compaction; design to take full account of the effects of soil adsorption capacity.
Comprehensive operation efficiency is high
The large hoisting and engine power, has the characteristics of single rope speed, single rope tension, work rate and less weight, with low working distance, comprehensive efficiency of construction machine at least 25% higher than ordinary compaction.
Strong working condition selectivity
It can realize the combination of heavy hammer low distance (24.4t * 14.4m) and light hammer high drop distance (17T x 20.5M), and the user selectivity is strong. The results show that the construction effect is best when the ratio of hammer weight to drop distance is 1.0~1.4. With different weight and low distance combination working condition, the total tamping number of single point is effectively reduced, the construction efficiency of dynamic compaction is greatly improved, and the construction period is shortened.
Strong tamping ability
Don't take the door frame when the maximum hammer weight of 24.4t, the maximum compaction can reach 350 t - m, can meet most dynamic construction requirements; with the door frame when the maximum hammer weight of 40t, the maximum compaction can reach 700 t - M.
Unique arm system
The boom system by increasing the angle steel truss structure thickened, including strong tamping special goose head, one hook separating device, a draw plate and double rigid amplitude damping anti backward device with special structure, good shock resistance, bump resistance, greatly improves the stability and reliability of the boom.
The wire rope has a high service life
In the quick release by phi 26 wire rope hoist system wide capacity, less winding number and high braking capacity, single rope tension up to 10-12t; large diameter wire rope pulley, large curvature radius; operation rate of wire rope bending less, fewer, low use cost.
Unique counterweight self assembly and disassembly system
Self removable counterweight system consists of A-frame, luffing system, anti roll bar and quick release winch etc., can realize the weight and arm self assembling, a comprehensive solution to the user in a remote area of disassembling the equipment and it is difficult to find the trouble of auxiliary crane.
Unique fast setting winch system
With a large diameter, wide, smooth drum drum, single rope capacity of more than 40m, a frame working rope does not exceed two, the wire rope is not easy to appear the phenomenon of disorderly rope, squashed. The bolt is connected between the mounting bracket and the rotary table, the support is rigid, and the coaxiality between the two supports is good. The connecting bolt adopts special bolt looseness proof device, which ensures the bolt not to be loosened during the strong shock and vibration, and ensures the stable operation of the quick release winch.
Unique clearance adjustment mechanism
The bolt and press plate type clearance adjustment mechanism is adopted between the frame and the lengthened beam of the crawler frame, which can eliminate the gap between the two, so as to ensure the stable operation of the whole machine.
After a detailed description of the small, you are not Liugong CM350 track tamper has more understanding of it? Efficiency comes from diligence. shortage in the play, line into Si destroyed with Liugong, keep self conscience, continue to carry forward the spirit of innovation, dare to challenge the old traditions, to create good products so fine!
