Embodiment Construction

[0011] see figure 1 , the present invention relates to a drill pipe grinder, comprising a frame 1, a hollow tube 2 is arranged horizontally on the top of the frame 1, and the top of the frame 1 is hinged to the middle of the hollow tube 2 through a hinged ear plate, so One end of the hollow tube 2 is fixed with a motor 3, and the other end is horizontally provided with a grinding wheel 4, and the grinding wheel 4 is connected to the output end of the motor 3 through a transmission shaft passing through the hollow tube 2, and the hollow tube 2 is close to the grinding wheel 4. Two handles 5 are fixed on both sides of one end, and the handle 5 is used to control the drill pipe grinder, and one end of the hollow pipe 2 can be pulled down so that the emery wheel 4 can be ground against the drill pipe. The drill pipe can be conveniently rotated when it is on the drill pipe bracket, so as to realize the all-round grinding of the pipe end of the drill pipe, which is not only convenie...

Abstract

The invention relates to a drill stem polisher which is characterized by comprising a rack (1), wherein a hollow pipe (2) is horizontally arranged on the top of the rack (1), the top of the rack (1) is hinged to the middle of the hollow pipe (2) through a hinging lug plate, a motor (3) is fixed on one end of the hollow pipe (2), a grinding wheel (4) is horizontally arranged on the other end of the hollow pipe (2), the grinding wheel (4) is connected with the output shaft of the motor (3) through a transmission shaft penetrating through the hollow pipe (2), and two handles (5) are fixedly arranged on two sides of one end, close to the grinding wheel (4), of the hollow pipe (2). The drill stem polisher has the advantages that the operation is convenient, the polishing effect is good, and the working efficiency is higher.

Description

technical field [0001] The invention relates to a drill pipe grinding machine, which is used for grinding the pipe end of the drill pipe for subsequent processing. Background technique [0002] Drill pipe is used in drilling for oil, gas, water and mineral deposits. Although the structure of the drill pipe is simple, its quality requirements are relatively high. During the production process of the drill pipe, it needs to be welded to reach the required length. Before welding, the pipe end of the drill pipe needs to be polished to remove the oxide layer formed by the heating of the drill pipe. [0003] In the past, when removing the oxide layer at the end of the drill pipe, it was necessary to manually grind the end of the drill pipe with a grinding machine, which is not only inconvenient to operate, but also has poor grinding effect and low efficiency. Contents of the invention [0004] The object of the present invention is to overcome the above disadvantages and provi...
