Problems solved by technology

Its disadvantage is that when the telescopic conveying line device is stretched out, the surfaces of every two adjacent transmission units are not in the same vertical position, and there is a drop between the two, forming a step 9, such as figure 2 shown
In this way, when the goods pass through the running steps, they will vibrate due to the drop and will not be stable.
In addition, the existing telescopic conveying line device has a complex structure and troublesome manipulation

Abstract

The invention provides a retractable conveying line device which comprises a plurality of conveying units. Each conveying unit comprises a left frame bar and a right frame bar which extend longitudinally. A plurality of conveying rollers which extend transversely are installed between the left frame bars and the right frame bars, and all the conveying rollers are sequentially arrayed in the longitudinal direction. In the stretching state of the retractable conveying line device, all the conveying units are sequentially connected in the longitudinal direction. In every two adjacent conveying units, a front buckling piece is arranged at the rear end of the frame bar of the precious conveying unit, a rear buckling piece is arranged at the front end of the frame bar of the later conveying unit, and the rear buckling piece of the later conveying unit and the front buckling piece of the precious conveying unit form a buckling cooperative relationship. Swing-arm type landing gears are furtherarranged on the conveying units. A lifting support and a vertical driving mechanism used for driving the lifting support to be vertically lifted up and down are further arranged. The invention further provides a retracting and stretching method of the retractable conveying line device. By means of the retractable conveying line device and the stretching and retracting method thereof, longitudinalstretching and retracting can be realized, and the surface is flat after longitudinal stretching is completed.

Description

Technical field [0001] The invention belongs to the technical field of conveying devices, and in particular relates to a telescopic conveying line device and an extension method and a contraction method thereof. technical background [0002] Telescopic conveying device is widely used in logistics system, especially in container packing. When a container packs goods, the operator usually carries the goods into the container, puts them away, then goes out of the container, and then carries them in again and again. This is repeated, and people need to go back and forth many times. Because of the huge volume and long longitudinal length of container province, the working intensity of operators is high and the working efficiency is low. [0003] Therefore, people have designed a conveying line device, which is densely provided with a plurality of transversely extending conveying rollers, and each conveying roller is arranged in turn along the longitudinal direction; When transporting ...
