Track device for piano production line

Abstract

The invention relates to a track device for a piano production line. The track device comprises tracks for communicating the piano production line and a plurality of bottom plates connected with the tracks respectively in a sliding manner, wherein a fixing structure used for fixing a piano is arranged on the upper surface of each bottom plate; each track comprises two sleepers which are arranged on the ground side by side; a plurality of silent rolling wheels performing circumferential rotation in the vertical plane are arranged at the tops of the two sleepers of each track in the extension direction of the sleepers; each silent rolling wheel comprises a rolling wheel formed by a wear-resistant silencing material and a supporting shaft; a rolling bearing is embedded into two ends of each rolling wheel; each rolling wheel is rotatably connected onto the corresponding supporting shaft through the corresponding rolling bearing; the two ends of each supporting shaft are respectively supported on a supporting seat arranged on the corresponding sleepers; the two sides of the lower surface of each bottom plate are connected with the rolling surface of the rolling wheels on the corresponding two sleepers in a sliding manner; an axial locating ring is arranged at one end of each rolling wheel and at a position corresponding to the outer side of the corresponding sleeper; the two side walls of each bottom plate are positioned between the axial locating rings of the rolling wheels on the corresponding two sleepers.

Description

technical field [0001] The invention relates to the field of track technology, in particular to a track device for a piano production line. Background technique [0002] In the production process of the piano, it needs to go through thousands of large and small processes such as accessory production, assembly, coding, and debugging. It must often move its position during the production process. Pay attention to avoid being bumped and worn, avoid severe vibration and bumps, especially in the tuning workshop, finishing, tuning and other debugging workshops, it is more important whether the piano is silent during the moving process. Due to the heavy weight of the piano, the traditional method of moving the piano is that several people work together to lift it. Later, it was developed to use mechanical equipment to move. However, the mechanical equipment will inevitably generate noise during operation. If the advanced silent transmission line at home and abroad is used, it is in...

Due to the heavy weight of the piano, the traditional method of moving the piano is that several people work together to lift it. Later, it was developed to use mechanical equipment to move. However, the mechanical equipment will inevitably generate noise during operation. If the advanced silent transmission line at home and abroad is used, it is inevitable. The increase in the production cost of the piano
