Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and 4, an oil rig winch drum suitable for multiple footbores includes a first and a second footbore winch drum that are interchangeable.
The first bottom diameter winch drum comprises a first left connecting hub 1, a first right connecting hub 5 and a first cylinder 4 arranged between the first left connecting hub 1 and the first right connecting hub 5; the first left connecting hub 1 is connected with a left connecting flange 3 through a pin shaft 2, and a plurality of pin shafts 2 are arranged along the circumferential direction; the first right connecting hub 5 is connected with a right connecting flange 6 through a pin shaft 2.
As shown in fig. 2-3, the first left connecting hub 1 and the left connecting flange 3 are positioned by a seam allowance; the first right connecting hub 5 and the right connecting flange 6 are positioned by a spigot.
The two ends of the first cylinder 4 are connected with the first left connecting hub 1 and the first right connecting hub 5 in a welding mode, and the inner diameter and the outer diameter of the first cylinder are matched with each other. After the integral connection assembly welding is formed, wire rope grooves are integrally processed on the first left connecting hub 1, the first cylinder 4 and the first right connecting hub 5.
