Self-balancing material vehicle

Abstract

The invention relates to a self-balancing material vehicle. Stand columns are connected to two sides of the back end of a base; the top parts of the two stand columns are connected mutually through atop plate; a liftable floating frame is arranged between the two stand columns and comprises floating vertical plates located on the inner sides of the stand columns and a floating bottom plate connected to the lower ends of the two floating vertical plates; the front sides and the back sides of the top parts of the two floating vertical plates are connected mutually through a floating top frame plate; vertical short plates extending forwards are symmetrically connected to the lower part of the floating frame; the front ends of the vertical short plates on two sides are connected mutually through a cross rod; a horizontal tray extending forwards is arranged on the cross rod; and a counterweight device is arranged on the floating frame. The fixed counterweight is equal to the empty weight of a floating piece, multiple counterweight springs are connected onto the floating bottom plate, and spring fasteners are fixed to the upper ends of the counterweight springs and are matched with C-shaped hooks. The elastic coefficients of the counterweight springs are the same or different. According to the material vehicle, a material box can be located at the appropriate height so as to be conveniently picked and placed, so that the working efficiency is improved.

Description

technical field [0001] The invention relates to logistics equipment, in particular to a self-balancing material vehicle, which belongs to the technical field of material transport vehicles. Background technique [0002] Automatic production lines or other workplaces often use material carts to transport material boxes to each station. The material boxes are placed on the brackets of the material cart. After the material cart reaches the destination station, the operator will remove the material from the material box. The defect during use is that the actual height of the material box is usually lower or higher than the suitable height for the operator to pick up the parts, which does not conform to the principles of ergonomics. [0003] When the position of the material box is too high, the operator needs to raise his arms or even stand on tiptoe to pick up the parts, which is not only laborious, but also prone to falling parts, which is dangerous to a certain extent. When ...

AI Technical Summary

Problems solved by technology

The defect in the use process is that the actual height of the material box is usually lower or higher than the height suitable for the operator to pick up the parts, which does not conform to the principle of ergonomics

[0003] When the position of the material box is too high, the operator needs to raise his arm or even stand on tiptoe to pick up the parts, which is not only laborious, but also prone to falling parts, which is dangerous

When the position of the material box is too high, it will make the operator very uncomfortable to directly pick up the pieces one by one from the material box, and the arm will be tired soon

When the position of the material box is too low, the operator needs to bend down to pick up the parts, which is also laborious and likely to cause waist discomfort for the operator

[0004] More often, there are multiple layers of material boxes stacked on the bracket of the material cart. If the position of the bracket is fixed, the operator needs to complete the high pick-up, middle pick-up and low-place pick-up in sequence. Frequent lifting of arms and bending over work may easily cause operator's arm fatigue and lumbar muscle strain, which is not conducive to labor protection and affects production efficiency

Especially if the operator has to pick up or put pieces from the material box thousands of times a day, whether the material box is at an ergonomic height will have a great impact on the operator's health or work efficiency
