Description

Material transportation trolley Technical Field The utility model belongs to the technical field of conveying devices, and particularly relates to a material conveying trolley. Background Traditional workshop handling mode mainly relies on the workman to operate simple and easy handcart and accomplish the short distance transportation of goods. Such carts typically consist of a flat bed, universal or directional wheels, and a metallic handle designed primarily to provide basic mobile load-bearing function for small, close-range material transfers in the workplace. However, with the expansion of industrial production scale and the increasing diversity of cargo types, the structural design of existing carts gradually exposes a number of technical drawbacks that are difficult to overcome: 1. The deck of a conventional cart is usually of a flat metal or wooden structure, and when goods are placed thereon, static friction and sliding friction generated between contact surfaces significantly affect the operation convenience. Particularly, when large mechanical parts, box forming raw materials or irregularly-shaped goods are carried, workers need to apply larger thrust to enable the goods to move on the vehicle plate, so that labor intensity is increased, and scratch or displacement of the surface of the goods is easily caused. 2. The sweep height of current handcart can't be adjusted according to actual operation demand, when needs carry goods to goods shelves upper strata, processing equipment feed inlet or transfer chain, the workman need carry with the help of extra bed hedgehopping instrument or many times, leads to operation procedure loaded down with trivial details and has the potential safety hazard. Disclosure of utility model In view of the above, the utility model provides a material transporting trolley, which solves the problems that in the prior art, the friction resistance of the existing workshop transporting trolley is large and the height adjustment cannot be performed. The technical scheme adopted by the utility model is as follows: The material transportation trolley comprises a bottom frame, two upright posts are symmetrically arranged on one side of the bottom frame, a supporting bracket is arranged above the bottom frame, the supporting bracket is arranged along the length direction of the bottom frame, the top of the supporting bracket is rotationally connected with a plurality of rollers, the rollers are arranged along the length direction of the supporting bracket, and a lifting device is further arranged on the bottom frame and used for driving the supporting bracket to lift. In the technical scheme, the underframe is formed by welding or assembling high-strength steel (such as Q235 or Q345 steel) or sectional materials, a stable supporting structure is provided for the whole trolley, and the surface of the underframe is subjected to rust-proof treatment so as to prolong the service life. The stand sets up in chassis one side, and the material is the same with the chassis, and the support bracket is made by aluminum alloy or light steel to lighten whole weight and guarantee bearing capacity simultaneously, and the cylinder adopts rigid plastic or stainless steel, and the surface is smooth in order to reduce coefficient of friction, along support bracket length direction even arrangement for bear and guide the material and slide, reduce the resistance in the material handling. The lifting device is used for driving the support bracket to vertically lift so as to adapt to the material loading and unloading requirements of different heights. The whole working principle is that when the material is placed on the roller of the support bracket, the sliding friction between the material and the support bracket is converted into rolling friction by the rotation characteristic of the roller, so that the friction force is greatly reduced, and workers can conveniently push or pull the material easily to carry out feeding and discharging operations. Meanwhile, the height of the bearing frame is adjusted through the lifting device, so that the bearing frame can be in butt joint with shelves, production lines or transportation equipment with different heights. In summary, the roller structure has the advantages that the roller structure obviously reduces material carrying resistance, reduces labor intensity of workers, improves operation efficiency, and the adjustable lifting function enables the trolley to adapt to various operation scenes, so that carrying intensity of workers is reduced. Preferably, the lifting device comprises an air cylinder and a connecting piece, wherein the air cylinder is vertically arranged on the underframe, and a piston rod of the air cylinder is connected with the support bracket through the connecting piece. In the technical scheme, the cylinder is used as an executing element, and the piston rod is driven by compressed air to linearly move so as to provide lifting powe
