Automatic anti-collision noise reduction device used on pipe gravity conveying frame

Abstract

The invention discloses an automatic anti-collision noise reduction device used on a pipe gravity conveying frame. The automatic anti-collision noise reduction device comprises a flat plate, a triggering rod, a pipe blocking hook and a stop pin. The triggering rod is rotationally connected with one side of the flat plate through a first spring and a first fixing shaft. The pipe blocking hook is rotationally connected with one side of the flat plate through a second spring and a second fixing shaft. A clamping groove is formed in one end of the triggering rod, and a movable groove is formed in one end of the pipe blocking hook. A hook hanging shaft is fixedly installed in the movable groove, and the hook hanging shaft is fixedly connected with the clamping groove through a third spring in a clamping manner. The stop pin is fixed on one side of the flat plate and is located above one end of the triggering rod. The triggering rod is in an arch shape, before the triggering rod and the pipe blocking hook rotate relative to the flat plate, the middle portion of the triggering rod is higher than the upper surface of the flat plate, the other end of the triggering rod is lower than the upper surface of the flat plate, and the other end of the pipe blocking hook is higher than the flat plate. According to the automatic anti-collision noise reduction device used on the pipe gravity conveying frame, due to the fact that the triggering rod, the pipe blocking hook and the flat plate are matched, mutual collisions of steel pipes in the rolling process are avoided, a buffering role is achieved on rolling of the steel pipes, and therefore noise generated by steel pipe rolling is lowered.

Description

[0001] Technical field: [0002] The invention relates to the technical field of batch collection of engineering pipes and rods thereof, in particular to an automatic anti-collision and noise reduction device used on a pipe gravity transmission frame. [0003] Background technique: [0004] In the batch continuous production of steel pipes, the horizontal delivery of the pipes is mainly driven by the motor to drive the rollers to rotate, and the vertical transfer and collection of the pipes are usually realized by chain conveyors or automatic rolling of the pipes under the action of gravity. Among them, although the chain delivery machine is stable in transportation and has advanced equipment, its application range is limited due to reasons such as high energy consumption during operation, high maintenance costs, and time-consuming maintenance. At present, the factory mainly adopts the rolling of the pipe under the action of gravity to realize the horizontal reversing of the pi...

Problems solved by technology

However, under the action of gravity, the rolling controllability of the steel pipe is low, and the rolling of the pipes on the pipe rack tends to collide with each other, making harsh impact sounds, and the noise often exceeds 110dB, which has become the main source of pollution in the production workshop
