Problems solved by technology

[0009] In response to the above phenomenon, someone proposed to connect the rotating shaft and the base flexibly, but in the specific use process, there are still certain defects: 1. Since the disc and the rotating shaft and the base and the rotating shaft are flexibly connected, the disc and the rotating shaft There is a lack of stability between the shafts and between the base and the rotating shaft, so the disk cannot be guaranteed to be in a horizontal state, and the cleaning of each drill bit cannot be guaranteed; 2. During the cleaning process, the water in each cleaning tank will pass through the drain hole and then through the drain The pipe is continuously drained outward, so the water in the cleaning tank will continue to decrease. After the water volume decreases to a certain extent, the cleaning effect will be affected; and in order to ensure the cleaning effect, it is necessary to stop the car and add water to each cleaning tank, but this method cannot meet the cleaning requirements. Continuous, which in turn affects the cleaning efficiency

Embodiment

[0025] The special-purpose cleaning device for the new type of drill in this embodiment includes a base 1, a rotating shaft 2, and a disk 3. The base 1 is provided with casters 4 with brakes, the bottom of the disk 3 is provided with a circular groove, and the center of the upper surface of the base 1 is provided with a socket. Groove 11, the upper end surface of insertion groove 11 is provided with a groove facing outwards and inner diameter is smaller than the inner diameter of insertion groove, and the lower end surface of rotating shaft 2 is provided with a protrusion 21 that cooperates with the groove, and then one end of rotating shaft 2 and base 1 The insertion slot 11 in the middle of the upper surface is plugged and fixed, the other end of the rotating shaft 2 is located in the circular groove, and the disc 3 can rotate around the rotating shaft 2 .

[0026] Also symmetrically hinged a support frame 13 on both sides of the upper end and the lower end of the rotating sh...

Abstract

The invention relates to a novel special cleaning device for a drill bit. The novel special cleaning device comprises a base, a rotary shaft and a disc; one end of the rotary shaft is inserted and fixed to the middle of the upper surface of the base, and the other end of the rotary shaft is fixedly connected with the middle of the disc; the upper surface of the disc is provided with three cleaningboxes of which the upper surfaces are open, the bottom face and the side face of each cleaning box are provided with a water outlet hole and a water inlet hole, a water outlet pipe is connected to each water outlet hole, the water outlet pipes are connected with a water collecting box, a water inlet pipe is connected to each water inlet hole, and the water inlet pipes are connected with a water supply box; and one ends of supporting frames are symmetrically hinged to the two sides of the upper end of the rotary shaft correspondingly as well as the two sides of the lower end of the rotary shaft correspondingly, the other ends of the upper-end supporting frames are fixedly connected with the bottom face of the disc through lock pins, and the other ends of the lower-end supporting frames arefixedly connected with the upper surface of the base through lock pins. The novel special cleaning device of the drill pit has the advantages that the occupied space can be decreased, transport is convenient, the stability between the disc and the rotary shaft as well as the stability between the base and the rotary shaft can be improved, water can be effectively supplied in the cleaning process,continuous cleaning is ensured, and accordingly, the cleaning efficiency is improved.

Description

technical field [0001] The invention relates to the research field of petroleum machinery and equipment, in particular to a drill bit cleaning device. Background technique [0002] The abbreviation of diamond compact (PDC) drill bit is a drilling tool commonly used in the oil drilling industry. [0003] The performance of PDC products continues to improve. Over the past few years, the quality and type of PDC cutting teeth have changed dramatically. If you compare the teeth of the 1980s with today's teeth, the difference is considerable. Due to the mixing Due to the changes in technology and manufacturing process, the quality and performance of today's cutting teeth are much better, which greatly improves the erosion resistance and impact resistance of the drill bit. [0004] Engineers also optimized the interface between the tungsten carbide substrate and the synthetic diamond to increase the toughness of the cutting teeth. Innovations in layered diamond processing have al...
