Molding Machine Of New Cement-soil Composite Pile Pile Rack Design

With the development of city construction, the application of cement-soil composite piling becomes more and more extensive. On the foundation of tallying up the structure characteristics of cement-soil composite piling and combining actual experience, a construction company puts forward a new technique of formatting cement-soil composite piling in one step. For adapting this kind of technique, we took our hand to the research and design of composite piling machine. In this task, the technique equipment has been already completed. This paper is mainly to study the performance of the pilling shelves.1. Comparing the domestic and foreign pilling-shelves on the pilling machines, we get the merits and shortcomings of each. So we can choose one type suited for this subject, and thus to design and virtually assemble it utilizing Pro/E.2. In this paper we analyzed all kinds of operating conditions on cement-soil composite pilling machine designed for this subject, and compare it with former piling machines. Because the operating conditions this time is much complicated, we analyzed the pilling shelf on all the operating conditions.3. Some key parts (leader) of the pilling-shelf are analyzed by static strength FEA under every operating conditions, and some design sizes are optimized. In order to insure the safety of the pilling-shelf, this paper checks the leader's stress, and calculates the stress through material-strength method.4. The operating conditions of leader rising is imitated by Virtual Prototyping technology, thus we got the variation curves about the leader-rising ability and each pole's inside dint with time during the prose. And then we gain the biggest dint-value, and analyze it through strength-method at that point. We compared it with the stimulation result, and found that the two results are essentially identical. So we can say that the imitated process is close to actual. Compare it with imitatedresult, then, we gain that the two result are similar, so, imitated process close to actual.With the FEA and the material-strength method, we learn that this piling shelf can satisfy the new-type cement-soil composite pilling machine's work. The analysis method and Virtual Prototyping technology applied on the operating conditions of leader rising provided an important reference for other pilling machine's design and study.
