A self-weight roller conveyor platform

Abstract

The invention relates to a dead-weight roller conveying platform which comprises a roller seat and a plurality of rollers. A roller mounting concave cavity is arranged on the upper surface of the roller seat, the rollers are rotatably mounted in the roller mounting concave cavity, bearing concave positions are arranged on the side walls, corresponding to the left end and the right end of each roller, of the roller mounting concave cavity, rotating shafts at the left ends and the right ends of the rollers are movably mounted in the bearing concave positions, locking clamping members positioned on the front side and the rear side of a roller body of each roller are arranged in the roller mounting concave cavity, the upper end of each locking clamping member is positioned between a horizontal plane where a roller core of the corresponding roller is positioned and a transmission contact face of the upper end of the locking clamping member, and the upper end of each locking clamping member extends towards the roller body of the corresponding roller and is close to in a noncontact manner to form a protruding clamping portion. The dead-weight roller conveying platform is simple in structure and convenient and quick to assemble, and processing difficulty and requirements on processing accuracy of the locking clamping members are low; during rolling, the rollers do not contact with the locking clamping members, so that wear of the locking clamping members is avoided, the dead-weight roller conveying platform is durable and good in locking effect, and products are stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of conveying platforms, in particular to a self-weight roller conveying platform. Background technique [0002] At present, the roller conveying platform is widely used in equipment for cargo transportation; the traditional roller conveying platform usually includes a roller seat and several rollers; the upper surface of the roller seat is provided with a roller installation The plurality of rollers are rotatably installed in the roller installation cavity, and the rotating shafts at the left and right ends of each roller are respectively stuck in the bearing recesses provided on the side walls of the roller installation cavity, and pass through The locking protrusion at the entrance of the bearing recess is locked in the bearing recess; the opening of the upper end of the bearing recess is slightly smaller than the lower end, which is similar to an inverted "Ω" shape. Although it is easy to install, it requ...

[0002] At present, the roller conveying platform is widely used in equipment for cargo transportation; the traditional roller conveying platform usually includes a roller seat and several rollers; the upper surface of the roller seat is provided with a roller installation The plurality of rollers are rotatably installed in the roller installation cavity, and the rotating shafts at the left and right ends of each roller are respectively stuck in the bearing recesses provided on the side walls of the roller installation cavity, and pass through The locking protrusion at the entrance of the bearing recess is locked in the bearing recess; the opening of the upper end of the bearing recess is slightly smaller than the lower end, which is similar to an inverted "Ω" shape. Although it is easy to install, it requires high production accuracy and assembly The intensity of the disassembly and disassembly process is high, and it is easy to cause the bearing concave position (locking protrusion) and the shaft part of the roller to wear, or even break the shaft part, resulting in unreliable installation of the roller shaft, which seriously affects the transportation stability of the roller conveyor device. good rate decline

For this reason, some manufacturers have designed to lock the rotating shaft of the roller in the bearing recess through side covers, pressing strips and other components, but there are many assembly parts, which is troublesome and inconvenient to assemble, which reduces the processing efficiency and increases the cost.
