Embodiment Construction
[0024] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0025] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

The invention relates to an unloading device and a dynamic compaction machine. The unloading device comprises a lever, a lever fulcrum, a retarder, a hook device and an unhook assembly. The lever can rotate around the lever fulcrum. The retarder and the hook device are both arranged on the lever and are located on the two opposite sides of the lever fulcrum correspondingly. The retarder comprises a retardance rail and retardance rollers, the retardance rollers can move along the retardance rail, and the retardance rail is configured to be capable of enabling the retardance rollers to accelerate descending along the retardance rail. The hook device is used for hanging or releasing a counter weight. The unhook assembly is connected with the retarder and the hook device so that the hook device can hang or release the counter weight along with changing of the state of the retarder. According to the unloading device, as the retardance rollers of the retarder can accelerate descending, the counter weight is driven to accelerate descending together with the hook device, then, the counter weight hung on the hook device is released, thus, the tensile force of a steel wire rope used for hanging the unloading device is decreased gradually, releasing of the counter weight is changed into slow descending, and impact of counter weight releasing on a system is reduced.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an unloading device and a dynamic compaction machine. Background technique [0002] Dynamic tamping impact machines rely on the high-altitude release of heavy hammers, and use the kinetic energy of the heavy hammers to impact and compact the ground. In order to lift the weight of tens of tons to an altitude of tens of meters and release it suddenly, the existing dynamic compaction machine often uses a winch equipped with a mechanical uncoupling device to achieve this operation requirement. [0003] The mechanical uncoupling device uses the self-locking mechanism to lock the weight, and is lifted to a height of tens of meters by the lifting action of the hoist. The connecting rod of the mechanical uncoupling device is pulled by the wire rope to instantly change the stable state of the mechanism of the mechanical uncoupling device, thereby releasing the weight instant...
