Abstract

The invention relates to the technical field of water conservancy construction, and discloses a water well drilling rig drill rod quick replacing device. Rotary connecting pieces are fixedly mounted on output shafts of telescopic rods and connected with adjusting devices, and rotary shafts are fixedly mounted at the positions, close to the two ends, of one side of a cross rod and movably connectedwith the adjusting devices in a sleeving manner, so that the adjusting devices are driven to rotate; drill rod devices are movably connected into the adjusting devices in a sleeved manner, so that the drill rod devices are replaced; and after replacement, the adjusting devices can rotate with the axes of the rotating shafts as the rotating centers through extension of the telescopic rods, so thatthe adjusting devices are put down, an operator can end the clamping relation between clamping pieces and clamping blocks to separate a left sleeve and a right sleeve, new drill rod devices are installed in the left sleeve and the right sleeve, the drilling progress is not affected while the drill rod devices are replaced, and the drilling efficiency of the device is improved.

Description

technical field

[0001] The invention relates to the technical field of water conservancy construction, in particular to a quick replacement device for drill rods of a water well drilling rig. Background technique

[0002] The water well drilling rig is an important water conservancy construction machine, which has the advantages of small size, high efficiency, convenient maintenance, and low price. It can be installed on a transportation platform as a whole, so as to quickly enter the construction site and perform positioning drilling. The rotating platform with the descending function drives the drill bit to rotate by connecting the drill pipe to the rotating platform. At the same time, the rotating platform descends and pushes the drill bit down for drilling. Every time the drill pipe is driven into the hole, the drill pipe needs to be disassembled and replaced. Install the new drill pipe and start drilling.

[0003] Although the cost of this drilling method is low and th...
