Plug-in assembled water well drilling rig

Abstract

The invention relates to a well drilling machine, in particular to a plugging-assembly type well drilling machine comprising a frame made of channel steels and / or angle iron, a power source, a gearbox, a hoist, a rotary machine head, a tower and a main drilling rod which is located in the rotary machine head. The power source, the gearbox, the hoist, the rotary machine head and the tower are fixed to the frame; a suspending pull rope is wound on a hoisting drum of the hoist, one end of the suspending pull rope penetrates a guide wheel of the tower to fix to an elevator, the elevator is connected to an elevating head, and a tap is fixed below the elevating head. The power source, the hoist, the gearbox and the rotary machine head are fixed to the frame through a plugging type connecting frame and a locking limit device. Thus, the plugging-assembly type well drilling machine has the advantages that structure is simple, disassembling is facilitated, transportation is benefited, well drilling efficiency is improved, one single well drilling machine is light, work intensity is reduced, and wells can be drilled without geographical restrictions.

Description

technical field [0001] The invention relates to a water well drilling rig, in particular to a plug-in assembled water well drilling rig with simple structure, fast loading and unloading, convenient handling, improved drilling efficiency, reduced labor intensity and no geographical restrictions. Background technique [0002] Water well drilling rig is also called water well drilling rig equipment. Water well drilling rig has different working modes, mainly positive circulation and pump suction reverse circulation. The working principle of water well drilling rig is very simple, mainly under the action of atmospheric pressure. The backwater ditch flows to the bottom of the well along the annular gap of the wellbore. At this time, the rotary table drives the drill pipe, drives the drill bit to rotate for drilling, and the negative pressure established by the suction of the mud pump sucks the debris mud into the inner cavity of the drill pipe, and then Rising to the faucet, it i...

Problems solved by technology

Yet the power source of prior art, the winch that is used for hoisting drilling rod, gearbox, the stay rope tower frame with tripod and machine head are all fixedly connected with frame by its own base and frame, and this connection mode is when loading and unloading. Quite time-consuming and labor-intensive, and not easy to transport

Existing water well drilling rigs are generally transported to the construction and drilling sites by transport vehicles, but in the hills or mountainous areas of our country, they need to be transported manually. The water well drilling rig is transported to the well drilling site and the drilling is abandoned, which makes it impossible for the small water well drilling rig to fully drill wells, which has geographical limitations

[0004] In summary, the prior art water well drilling rigs are complex in structure, bulky and heavy, unfavorable for handling, time-consuming and labor-intensive for loading and unloading, labor-intensive workers, long preparation time for drilling, and low drilling efficiency
