Anti-colliding and noise-reducing device for oil pipes

Abstract

The invention relates to an anti-colliding and noise-reducing device for oil pipes, belonging to the technical field of environmental-friendly noise-reducing devices in oil pipe repairing equipment of oil industry. The anti-colliding and noise-reducing device consists of a fixed bracket, an air cylinder, a movable hanging frame, a height adjusting screw rod, a suspension steel wire rope, buffering rubber rods, a normally-opened universal travel switch, a normally-opened power-off delay relay, and a two-position five-way electromagnetic gas valve. The upper end of the fixed bracket is articulated with the oblong movable hanging frame and is connected with the movable hanging frame by the air cylinder; a group of rubber rods is suspended at the external side of the movable hanging frame by using the height adjusting screw rod and the thin steel wire rope; the air cylinder is connected with the electromagnetic gas valve by using a gas pipeline; and the electromagnetic gas valve is connected with a control device by using electrical wires. According to the anti-colliding and noise-reducing device for the oil pipes disclosed by the invention, the rubber rods are suspended by the hanging frame, so that the rolling collision among the oil pipes is avoided; and meanwhile, an automatic control mechanism for sensing delay is designed, so that the noise produced by the oil pipes in rolling collision on a bridge frame is greatly lowered.

Description

technical field [0001] The invention relates to an oil pipe anti-collision noise reduction device, which belongs to the technical field of environmental protection noise reduction devices in oil pipe repair equipment in the petroleum industry. Background technique [0002] Oil pipes are widely used in the exploration, development and production of oilfields in the petroleum industry, and the repair work of oil pipes is mainly carried out on the oil pipe repair line equipment in the oil pipe factory. The oil pipe bridge is an important device used to store the oil pipe and transition between processes in the oil pipe repair line equipment, but when the oil pipe rolls and collides on the bridge, it will make a strong noise, which has a very bad impact on the working environment. Oil pipe collision noise is the main noise source in oil pipe factory, and it is extremely harmful. [0003] The patent No. 200920030389.9 is a oil pipe buffer noise reduction device. Although it can ...
