Description

Technical Field

[0001] This utility model relates to the field of drilling technology, specifically to a tooling for connecting a mud pump to a suction pipeline. Background Technology

[0002] Mud pumps are important components in drilling engineering. They deliver the surface flushing medium—clean water, mud, or polymer flushing fluid—under certain pressure through high-pressure hoses, swivels, and the center hole of the drill string directly to the bottom of the drill bit. This is to cool the drill bit, remove the cuttings, and transport them to the surface. To facilitate the connection of pipelines, a connection tool is installed between the mud pump and the suction pipeline. Chinese utility model patent CN212155127U discloses a connecting device for an oil drilling mud pump, including a first pipe and a second pipe. The first pipe is installed on one side of the second pipe. A first disc is installed on the side of the first pipe near the second pipe, and a first guide hole is opened at the center of the first disc. Guide rods are evenly distributed on the outer surface of the first disc near the second pipe. A second disc is installed on the side of the second pipe near the first pipe, and a second guide hole is opened at the center of the second disc. A guide groove adapted to the guide rods is opened on the outer surface of the second disc near the first pipe. The guide rods are inserted into the guide grooves and slidably connected to the inner wall of the guide grooves. The first pipe is brought close to the second pipe, and the guide rods on the first disc are inserted into the guide grooves on the second disc. At this time, bolts are connected by threaded connection through threaded holes and threaded blind holes. This invention facilitates the rapid docking and installation of multiple pipes during long-distance transportation. Based on existing solutions and actual production and processing, the existing tooling for connecting the mud pump and the suction pipeline is prone to loosening and falling off when the pump body vibrates, resulting in an unstable connection. Therefore, we propose a tooling for connecting the mud pump and the suction pipeline to solve the problems mentioned above. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tooling for connecting a mud pump to a suction pipeline, comprising a suction pipe body, a suction head, a mud pump connecting pipe, and a connecting flange. Suction heads are fixed at equal intervals at the top of the suction pipe body, and a mud pump connecting pipe is provided above the suction heads. A connecting flange is fixed at the top of the suction heads and the bottom of the mud pump connecting pipe, and a sealing ring is installed at the inner end of the connecting flange. A square head screw is installed inside the connecting flange, and a reinforcing plate is provided on the outer side of the connecting flange. A rectangular plate is integrally connected to the top of the reinforcing plate, and a rectangular groove is opened inside the rectangular plate.

[0005] Preferably, the connecting flange has threaded holes at equal angles inside.

[0006] Preferably, the reinforcing plate has a fan-shaped structure, and the reinforcing plate and the square head screw are arranged in a one-to-one correspondence.

[0009] Preferably, the inner side of the reinforcing plate is fitted to the outer side of the connecting flange.

[0010] Preferably, a nut is installed at the bottom end of the square-headed screw.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the tooling for connecting the mud pump and the suction pipeline uses a rectangular groove to limit the square head screw, preventing the square head screw from rotating and falling off, and uses a reinforcing plate to improve the connection stability. 1. After connecting the suction head to the mud pump connecting pipe, the two sets of connecting flanges are fixedly connected by square head screws and nuts. A reinforcing plate is installed on the outside of the connecting flange. The inner side of the rectangular groove fits against the outer side of the square head screw. The rectangular groove restricts the square head screw and prevents it from rotating and falling off. 2. Reinforcing plates fixed at equal angles surround the outside of the connecting flange to improve waterproof performance. The reinforcing plates set at equal angles are fixedly connected by rectangular plates and screws to improve connection stability. Attached Figure Description
