Front carriage structure of electric mountain geophysical drilling rig

Abstract

The invention relates to a front carriage structure of an electric mountain geophysical drilling rig, and belongs to the field of oil and gas geophysical drilling equipment. The front carriage structure mainly comprises a chain lifting structure, an arc-shaped underframe structure, a clamp type telescopic rod structure, and a chain lifting device and arc-shaped underframe rotation and locking structure; a power-off brake in the chain lifting structure can control the lifting and drilling of a drilling tool well, with short response time; an encoder records the rotation of a chain wheel in realtime; the arc-shaped underframe structure is highly stable and safe, and can be transported by multiple people; more counterweights can be plated when the electric geophysical drilling rig is in operation; the clamp type telescopic rod structure is convenient to adjust the length of a pull rod, spherical hinge structures are arranged at the upper and lower ends of the pull rod, and have a large degree of freedom; and the chain lifting device and arc-shaped underframe rotation and locking structure is easy to disassemble, and a chain lifting device can be directly placed on the arc-shaped underframe in an inverted manner for transporation.

Description

technical field [0001] The invention relates to a front carriage structure of a mountain geophysical exploration electric drilling rig, which belongs to the field of oil and gas exploration equipment. Background technique [0002] Mountain geophysical drilling rigs are one of the main equipment for oil and gas resource exploration. Their exploration fields are mainly in areas with complex geological conditions such as mountains and hills. The exploration operations are characterized by high exploration density, heavy tasks, and high difficulty. The front carriage of the mountain geophysical exploration rig is an important part of realizing tripping, drilling and jam release, which puts forward higher requirements for the transmission convenience, stability and adaptability of the front carriage structure of the mountain geophysical exploration rig. At present, the drilling tool in the lifting of the front car structure of the mountain geophysical drilling rig has inertia, an...

AI Technical Summary

Problems solved by technology

At present, the drilling tool in the lifting of the front car structure of the mountain geophysical drilling rig has inertia, and the rapid stop of the guiding device cannot be realized. There is no intelligent control of the working conditions of the mountain geophysical drilling rig, and it is impossible to clearly understand its operation process; the chassis structure is mostly straight. type, less involved in the curve, and poor adaptability; the two tie rods are mostly connected by bolts, and the length adjustment is inconvenient
