AI Technical Summary

Technical Problem

During the use of existing electric drilling machines, the drill bit is stressed on the bottom of the drilling structure due to the long-term unremoval, making it difficult to disassemble manually and is inconvenient to disassemble.

Method used

An indoor electric drilling machine is designed, including a vertical cylinder, a support ring, an electro-hydraulic cylinder, a motor, a drilling rod and a loose push-off structure. The electric telescopic rod drives the transmission rod and the transmission column downward, and cooperates with the design of the inverted T-shaped part and the L-shaped positioning rod to automatically push and drop and disassemble the drill bit.

Benefits of technology

It greatly improves the efficiency of disassembly and replacement of drill bits, solves the problem of inconvenient disassembly of drill bits, and improves the efficiency of equipment use.

Abstract

The utility model discloses an indoor electric well drill, and belongs to the technical field of well drills. An indoor electric well drill comprises a vertical cylinder, the bottom end of the vertical cylinder is fixedly connected with a supporting ring, the bottom end of the supporting ring is fixedly connected with a plurality of plug pins arranged in an annular array, the inner side of the vertical cylinder is fixedly connected with an electric hydraulic cylinder through a connecting plate, the telescopic end of the electric hydraulic cylinder is fixedly connected with a motor, and the motor is fixedly connected to the top end of a movable plate. The movable plate is slidably connected to the inner side of the vertical cylinder, an output shaft of the motor extends to the bottom of the movable plate and is fixedly connected with a drilling rod, the outer side of an inverted-T-shaped part arranged at the bottom end of the drilling rod is movably sleeved with a drill bit, and a sleeve groove matched with the inverted-T-shaped part is formed in the top of the drill bit. When the indoor electric well drill is used, splash generated during drilling can be blocked under the action of the vertical cylinder and a plurality of plug pins at the bottom of the supporting ring when a well is drilled and dug indoors, and the splash is prevented from moving around to injure constructors.
