Rammer release device of dynamic compactor

Abstract

The invention discloses a rammer release device of a dynamic compactor. The rammer release device of the dynamic compactor comprises a lifting frame and a lifting hook. A lifting block is installed inside the lifting frame. The lifting hook comprises a hook handle section at the upper portion and a hook holding section formed by notching the lower portion of the lifting hook. A connecting frame is hinged to the lower end of the lifting frame. The lower end of the connecting frame is hinged to the middle of the lifting hook. A rammer release device is hinged to the middle of the connecting frame and comprises a rammer release steel wire rope and a transverse frame extending out of the connecting frame. One end of the transverse frame is hinged to the middle of the connecting frame. The other end of the transverse frame is fixedly connected with the head end of the rammer release steel wire rope. The tail end of the rammer release steel wire rope winds around the upper end of the lifting frame. A stop shaft is installed at the position, corresponding to the hook handle section, of the middle of the transverse frame. The transverse frame is hinged to the connecting frame through a hinge pin. Compared with a traditional rammer release device of the dynamic compactor, the rammer release device of the dynamic compactor has the advantages that the structure is simple, the opening degree is large, a rammer can be hooked conveniently, and working efficiency of workers is improved. According to the rammer release device of the dynamic compactor, the lifting frame and the lifting hook are connected through the connecting frame, so that the free height of the rammer release device is decreased effectively, and rammer release reliability is improved.

Description

technical field [0001] The invention relates to a hammer removing device for a dynamic compaction machine. Background technique [0002] The dynamic tamping machine is a mechanical equipment used for tamping the foundation in engineering construction. It mainly uses the strong impact force generated by the free fall of the rammer to increase the strength of the foundation and reduce the compression of the foundation by repeatedly raising the rammer to a certain height and releasing it. The purpose of improving performance, improving earthquake resistance and eliminating ground subsidence. During the dynamic compaction operation, the dynamic compaction machine lifts the rammer to a certain height through the self-locking function of the hammer-removing device body, and releases the self-locking of the hammer-removing device under the action of external force to make the rammer fall freely to complete a tamping operation . [0003] At present, there are four defects in the h...

AI Technical Summary

Problems solved by technology

[0003] At present, there are four defects in the hammer release device commonly used in dynamic tamping machines: 1. The hammer release wire rope is easy to touch the tamper, which reduces the stability of the hammer release; 2. The traditional load-bearing hook and the release hook are combined through a flexible hammer release wire rope The hammer removal device is formed. The combined hammer removal device has a high free height, which not only reduces the lifting height of the rammer and the rated tamping performance, but also increases the shaking amount and shaking time of the device after the hammer removal, which affects the working efficiency of the dynamic compaction machine; 3. The hammer removal device is bulky. When lifting the tamper, the independent release coupler must be removed, and then the hoisting sling is connected to the hook to realize it. It is difficult for workers to hang the hammer and the operation is complicated; 4. The traditional hammer removal device is complicated to manufacture and high cost
