Look at this big thing-the birth of 36-inch three-cone bit _ hoisting

Original title: Look at this big guy-the birth of 36-inch three-cone bit Inch: Inch. Jiangzuan Company introduced Hughes technology from the United States and continued to use international units. Oh my God! The cone is so big! That's an exaggeration! Recently, a 36-inch cone drill bit accessory appeared in the assembly workshop of Qianjiang Manufacturing Plant of Sinopec Machinery Jiangdian Company. The cone of a drill bit accounted for more than half of the whole material plate, which attracted workshop workers to stop and watch. While everyone was marveling at how big it was, they were all talking about how to put this big thing on the palm of the tooth? "In fact, this is not very difficult, the principle is the same as the smaller three-cone bit sub-assembly, the only difficulty is that the size is too large, the weight is too heavy, every move, turnover, detection, are extremely laborious, but also need to pay attention to production safety at all times." Shi Zhenghua, head of the sub-assembly class, Tapered Rock Bit , introduced. Before the 36-inch drill bit arrived at the workshop, the sub-assembly team re-inspected and maintained all the hoisting equipment of the team, replaced all the wire ropes with fluff, and replaced all the cranes with insufficient hoisting load to ensure that the hoisting process was absolutely safe. At the same time, all operators were trained in large-size bit hoisting and simulated in practice. In the process of sub-assembly of 36-inch large drill bit, the sub-assembly personnel in the assembly workshop successfully realized the task of safe, high-quality and efficient assembly according to the pre-simulated steps. It was not easy to say at that time. Assembler Ren Jun said with a lingering fear: "Although we have all installed a 34-inch large-size drill bit, and we have done a lot of preparatory work in the early stage, when we really started, we found that the 36-inch drill bit was really too heavy. Four or five people had to work together at the same time to adjust the coaxiality and height difference of the drill bit, so that the smaller size would not move."; The strength was so great that it moved a few millimeters, and everyone's clothes were all wet. When the drill bit has just been welded and the drill bit is still hot, the workshop staff can't wait to take a picture as a souvenir. Look, this is the 36-inch drill bit created by Jiangdian staff with concerted efforts. Sinopec Jiangdian Machinery Co., Ltd. has the annual production capacity of 50000 sets of roller bits, covering 31/2 inches to 36 inches in size, ranking first in the world,dth drilling hammer, and has continuously obtained the right to use API monogram in the United States, and has passed the international ISO 9001 quality system certification review and HSE system certification audit.
