Drill pipe dismounting device for pile driver

Abstract

The invention belongs to the technical field of construction equipment, and particularly relates to a drill stem dismounting and mounting device of a pile driver. By adopting the drill stem dismounting and mounting device, the problems that current drill stems of the pile driver are not convenient to dismount and mount and the like are solved. The drill stem dismounting and mounting device comprises a rack, wherein a grouting plate which is connected with a power head is movably arranged on the rack; a plurality of grouting plate connectors are arranged on the grouting plate in a penetration manner; the grouting plate connectors are separately connected with the grouting plate through a peripheral rotary connection structure; a plurality of drilling stem bodies which are in one-to-one correspondence with the grouting plate connectors are arranged below the grouting plate connectors; the drill stem bodies are connected with the grouting plate connectors through threaded connection structures; and peripheral positioning structures which can peripherally position the drill stem bodies and the grouting plate connectors are arranged between the drill stem bodies and the grouting plate connectors. The drill stem dismounting and mounting device has the advantages that the structure is simple and reasonable; the connection parts of the drill stems and a grouting mechanism are convenient to dismount and mount; the stability is good; the connection strength of the drill stems is high; the drill stems are not separated from the grouting plate easily during peripheral rotation; and peripheral positioning of the drill stems and the grouting plate connectors are realized through pressure plate drivers.

Description

technical field [0001] The invention belongs to the technical field of construction equipment, in particular to a drilling rod dismounting device for a pile driver. Background technique [0002] At present, there are two types of piling machines used on construction sites: one is the rotary piling machine. The structure of this piling machine is a drill pipe suspension frame pulled up by a hoist, and the drill pipe bit is driven by the power head to form a hole in the underground drilling machine. The other is the impact hammer pile driver. The structure of this pile driver is to use the hoist to pull up the impact hammer and drop it repeatedly, and then lift it to realize pile driving. Among them, the rotary pile driver mainly realizes the purpose of drilling the underground drill pipe through the circumferential rotation of the drill pipe during piling. However, due to the long length of the drill pipe during actual construction, it is inconvenient to install and disassemb...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned solution solves the problem of poor stability of the drill pipe of the existing piling machine to a certain extent, but the solution still exists: the connection between the drill pipe and the grouting mechanism is not convenient to disassemble, the connection strength is low, and the problem of mutual detachment is easy to occur
