Car transshipment device for accumulation conveying

Abstract

The invention discloses a car transshipment device for accumulation conveying. The car transshipment device for accumulation conveying comprises steering and driving devices mounted on annular tracks and used for driving conveying cars; the steering and driving devices are expansion pin devices; the expansion pin devices comprise a chuck, ball head cylindrical pins, shaft sleeves and compression springs; a through hole used for connecting with rotating shafts is formed in the central position of the chuck; a plurality of counter bores are uniformly formed in the outer circumferential wall of the chuck; the ball head cylindrical pins, the shaft sleeves and the compression springs are mounted inside the counter bores; the ball head cylindrical pins are spaced by the shaft sleeves and are supported by the compression springs, so that the ball head cylindrical pins are provided with outward elasticity; clamping strips are mounted at the bottom of the conveying cars; clamping grooves used for being matched with the outer ends of the ball head cylindrical pins are formed in the bottom surface of the clamping strips. According to the car transshipment device provided by the invention, through the hardwired transmission between the ball head cylindrical pins and the clamping grooves, the transshipment of the conveying cars is realized; the transmission connection is extraordinarily reliable; the bearing capability of the conveying cars is allowed to be relatively high; the operation stability is further remarkably improved; the entire trolley transshipment device is small in abrasion and long in service life.

Description

technical field [0001] The invention relates to an accumulation type conveying device, in particular to a trolley transfer device for accumulation type conveying. Background technique [0002] The material conveying system is an important means of "loading, unloading and handling", which has penetrated into all fields of modern mass production. With the continuous advancement of science and technology, as well as the wide application of assembly line operations and robot technology, material transportation is no longer a simple "loading and unloading". Precise uniqueness of end material location or state. [0003] The accumulative and free conveying device is a conveying device capable of conveying and temporarily storing items, including a chain conveying track, a chain drive device, a circular track and a steering drive device. At both ends, the steering drive device is installed on the circular track to make the conveyed trolley transition and turn smoothly on the circu...

AI Technical Summary

Problems solved by technology

This structure relies on the friction between the extrusion wheel and the extrusion ring to achieve the purpose of transferring the trolley, so its load capacity is not large enough, and the mass of the trolley that can be transferred cannot be too large, sometimes slipping may occur, and the running stability is also poor. It needs to be improved, and the extrusion wheel and extrusion ring are easy to wear, and their service life is short
