Cantilever crane gooseneck boom for dynamic compaction machine and dynamic compaction machine

Abstract

The invention discloses a cantilever crane gooseneck boom for a dynamic compaction machine. The cantilever crane gooseneck boom comprises a cantilever crane gooseneck boom body. The cantilever crane gooseneck boom body comprises a first side plate, a second side plate, a first sealing plate, a first box-type beam plate, a second box-type beam plate, an upper cover plate and a lower cover plate, wherein the first sealing plate is arranged close to the bent position of the first side plate and the bent position of the second side plate, one end of the first sealing plate is connected with the first side plate, the other end of the first sealing plate is connected with the second side plate, the first box-type beam plate and the second box-type beam plate are located between the first side plate and the second side plate, the head of the first box-type beam plate is connected to the head of the first side plate, the head of the second box-type beam plate is connected to the head of the second side plate, the tail of the first box-type beam plate and the tail of the second box-type beam plate are connected to the first sealing plate, and the upper cover plate and the lower cover plate are connected with the first side plate and the second side plate. The cantilever crane gooseneck boom is provided with a box-type structure, the box-type structure can guarantee uniformity of stress on the cantilever crane gooseneck boom, and therefore the stability of the whole cantilever crane gooseneck boom is greatly improved; meanwhile, the cantilever crane gooseneck boom is simple in structure and easy to manufacture. The invention further discloses a dynamic compaction machine.

Description

technical field [0001] The invention relates to the field of large machinery, and more specifically, relates to a goose head of a boom frame of a dynamic ramming machine and a dynamic ramming machine. Background technique [0002] The goose head of the jib is designed according to the working conditions of the dynamic compaction machine, and it is usually a forward-looking structure with an elevation angle. Since the goose head of the jib protrudes forward, the distance between the weight and the jib is relatively large. Even if the released hook and unhook shake, they will not touch the jib, thus protecting the jib from collision. hurt. In addition, since the goose head of the jib frame is raised upwards and protrudes forward, the distance between the goose head of the jib frame and the jib frame will become larger, so it is convenient to install the mast at the bottom of the goose head of the jib frame for Support the boom to ensure the stability of the boom during work....

Problems solved by technology

[0003] However, the existing jib goose head has the disadvantages of complex structure and poor stability, which affects the manufacture and use of dynamic compaction machines
