A new type of water well drilling rig

Abstract

This patent application relates to a ground drive device for rotary drilling, and specifically discloses a new type of water well drilling rig, including a frame on which a power system, a hydraulic system, and a drilling system are installed. The hydraulic system includes a hydraulic pump and an oil tank. and multi-way valve, the hydraulic pump is set on the frame, the oil tank is set above the hydraulic pump, the multi-way valve is set on one side of the oil tank, the power system is connected with the hydraulic pump, the drilling system includes the mast and the power head, and the mast is equipped with Chain, the chain is driven by the first hydraulic motor, the two ends of the chain are connected to the upper and lower ends of the power head, and the power head is slidably connected to the mast, and the second hydraulic motor and the power head are arranged on the power head. The second hydraulic motor is connected to the power head, and the first hydraulic motor and the second hydraulic motor are connected to the multi-way valve; this patent application intends to provide a new type of water well drilling rig with good sealing performance and high drilling quality to solve the problem of the existing power head There are problems of poor sealing and low drilling quality.

Description

Technical field [0001] The invention relates to a ground driving device for rotary drilling, in particular to a new type of water well drilling rig. Background technique [0002] Mountain drilling rigs are also called human-lifting mountain drilling rigs. The human-lifting type can be carried away by people. In terms of engineering, it can be moved by people during the drilling process. It is more suitable for mountains, loess plateaus, hills, etc. Exploration and drilling of complex surfaces such as Gobi and farmland. [0003] The existing mountain drilling rigs have been improved, generally including the base, mast, hydraulic system and power system. The mast is fixedly connected to the base, and the mast is slidingly connected by the power head base, the power head base and the lifting system on the mast. The first hydraulic motor is connected to the lifting system, the power head is installed on the power head base, and the second hydraulic motor is connected to the power head...

AI Technical Summary

Problems solved by technology

[0004] In the past, the power head using medium water, the sealing structure includes a gasket, the gasket surrounds the main shaft, and a multi-layer rubber ring is placed on the gasket to prevent water from flowing out of the power head, and then the bearing is directly installed on the rubber ring; When the mountain drilling rig is working, since the main shaft and the inner ring of the bearing are rotating rapidly and continuously, the rubber ring is easily worn, so the internal sealing of the power head is poor. After a period of time, the medium water will flow from the worn rubber pad. outflow, the operator will disassemble the power head and replace the rubber pad inside, which is troublesome to operate and frequent replacement

[0005] On the other hand, when the existing mountain drilling rigs are drilling, due to the rotation of the drill bit and the interaction between the drill bit and the ground, the drill bit will often have a large vibration offset, which will also cause a large vibration offset to the mast, and the mast will also Drive the drill bit to have a large vibration offset, and the drill bit will drill a well with irregular and large diameter, which will affect the drilling quality
