Device and method for connecting or disconnecting drill rod and power head of hole-forming pile machine

Abstract

The invention discloses a device and method for connecting or disconnecting a drill rod and a power head of a hole-forming pile machine. The device comprises a cylindrical supporting body, a remote controller, a lifting lug and a steel wire rope, wherein the upper end of the cylindrical supporting body is a connector used for being fixedly connected with the power head in an inserted mode on the ground, the lower end of the cylindrical supporting body is a sleeve, the sleeve and the connector are coaxial, the sleeve is used for being sleeved with the top end of the drill rod, and a supporting frame is fixedly connected to the cylindrical supporting body; two linear telescopic mechanisms are arranged on the supporting frame, telescopic rods of the linear telescopic mechanisms are used for being inserted into a first through hole in the wall of the sleeve, a radial inserting groove in the top end of the drill rod and a second through hole in the wall of the sleeve so as to be fixed or disengaged, and the linear telescopic mechanisms are electrically connected with a main controller arranged on the supporting frame; a transmitting part of the remote controller is operated by ground personnel; and the lifting lug and the steel wire rope are used for vertically lifting the drill rod right below a central hole of the sleeve so as to facilitate mutual sleeving. By means of the device and the method, the drill rod and the power head can be fixed in an inserted mode or pulled out to be disengaged without climbing up to the height of dozens of meters manually.

Description

technical field [0001] The invention relates to the technical field of pile foundation construction equipment, in particular to a device and method for connecting or disconnecting a drill pipe and a power head of a hole-forming pile machine. Background technique [0002] With the rapid development of urban construction, there are more and more high-rise buildings and super high-rise buildings. The higher the building, the deeper the pile foundation is required, and the longer the length of the drill pipe is. However, based on the stability and safety of the drilling rig, the length of the drill pipe cannot be too long. Therefore, generally speaking, the drilling A hole such as drilling a hole about 70 meters deep requires at least two drill rods to complete. The hole-forming pile machine of a traditional power head or claims drilling rig, need manually climb up the height insertion plug of about 35 meters or throw off the plug and go up and down two to three times.

Problems solved by technology

[0004] But in the prior art, due to the following situations, it is still necessary to manually climb up to a high place of tens of meters to insert the plug to connect or disengage the plug to extract the plug to replace the drill pipe: 1, the second drill pipe and the second power head Initial connection; 2. Replace the second drill pipe with different lengths according to the drilling depth; 3. Use several short drill pipes to connect each other to form a second drill pipe; 4. Replace different length
