Abstract
The utility model relates to a strong tamping machine, belonging to a construction machine for foundation treatment, and comprising a lifting part, a shifting part and a supporting part. The utility model is characterized in that the supporting part is a rigid vertical framework which is inclined inward in a definite angle and comprises three upright posts 5, an upper cover 12 and a bottom board 4. Simultaneously the length of the upright posts 5 can be adjusted. The utility model has the advantages of eliminating the instable element caused by the supporting resilient force and conveniently carrying the operation of shifting and walking and overcomes the defect that the arm rod of a crane is used as a three-point form support, and the power part uses a windlass instead of a crawler crane, thus greatly reducing cost and constructing expenses. The safety is ensured, the efficiency is enhanced, and one machine has a plurality of functions.
Description
The invention belongs to Foundation Treatment machinery.
Existing dynamic compaction machinery pattern is prepattern still, and its common ground all is to utilize a crawler crane to finish to promote hammer ram and be shifted, and difference mainly is bearing mode.A kind of form such as the disclosed scheme of Chinese patent CN2058187U dynamic compaction machinery, this scheme advantage is, the carrying of three fulcrums, good stability when ramming work, but during the displacement of rammer machine, lift by crane the armed lever walking, need lifting separately to move hammer, because armed lever and gooseneck boom beam consolidation, Gu Etouliang and Men Liang hinged place become the suspension centre of crane, this suspension centre has increased the span of a gooseneck boom beam than the radius of gyration of former machine suspension centre, at this moment, plays overhang-door beam action power, crane has been produced the bigger moment that leans forward, armed lever is produced a huge moment of flexure, and former armed lever is difficult to bear, and must make and strengthen armed lever.Strengthen weight that armed lever increases and gooseneck boom beam, pulley, suspender weight all at separately position of centre of gravity, crane is produced certain additional moment that leans forward, cause crane to have exceeding the quata turning round or surpass the trend of the load of tumbling, displacement brings great inconvenience to driver operation, especially when the rammer machine shifts another capable displacement, needs the tune of rammer machine to move hammer, meet the small size works area, thisly move upright increased frequency, efficiency of construction is fallen greatly, and this is a scarce limit that causes that stability is bad.Another kind of form, by fixed gooseneck boom on the armed lever, thereunder hinge is tied a both legs steel door frame scheme, this scheme walking stability is good, and shortcoming is that job stability is bad: during construction operation, for preventing the armed lever bounce, the back of the body rope of armed lever almost is in relaxed state, make almost all load by the supporting of door frame two columns, behind the lifting hammer ram, when one of them column meets backfill heatable adobe sleeping platform or local soft loosened soil ground, this column sink slowly, so that door frame tilts slowly, if there is not the emergence disconnecting measure, the driver often takes " put rope and throw away hammer ", to cause mechanical accident, if have little time to take any measure, the meeting car crash, consequence is serious.
Task of the present invention is to provide a kind of dynamic compaction machinery for the forced ramming reinforcing foundation construction operation, make it to have one stressed rationally, be adapted to the strong bearing support that rams, select typing equipment optimization dynamic compaction machinery commonly used in the engineering, so that strengthen construction stability and displacement conveniently, guarantee safety, improve work efficiency, reduce cost, and promote the dynamic compaction machinery typing.
Concrete scheme is: by lift portion, and displacing part, supporting part is formed.
