Description

Horizontal trolley

Technical field

The utility model relates to a kind of chassis of the usefulness of transporting goods.

Background technology

In existing Horizontal trolley, comprise base, be arranged at the below caster wheel of base, connect as one and be positioned at the column of base both sides with base, the back timber that is connected with two column tops; Described column is provided with guide rail, and a connection box is provided with guide wheel, and this guide wheel is positioned at described guide rail, and connection box and supporting plate are fixedly connected; The bottom of main spring is connected on the connection box, and hang on described back timber the upper end of main spring.Connection box is by guide wheel upper and lower moving on the guide rail of column, and it is also upper and lower mobile to drive supporting plate.In the material handling process, usually need to carry simultaneously a plurality of the same article, and need stack to be deposited on the supporting plate, before placement, bend in several article like this, and behind the constantly folded height of stacking material, need when placing the several article in back on tiptoe and lift highly, these actions certainly will cause the fatigue of operating personal, influence work efficiency.Therefore be hung on the back timber by main spring with connection box, constantly piling up in the process of object, weight of object on the supporting plate is also in continuous increase, make the stressed increasing of main spring, then supporting plate also constantly descends, and the collapsing length owing to main spring is directly proportional with stressed like this, so article of every increase, then can make fixing length of spring stretching, if this regular length just equates that with the Individual Items height then the height of uppermost article remains constant.This spring can only be applicable to a kind of article, and the height of unit article and weight have change slightly, will keep the requirement of supporting plate height unmodified by out of reach, and need the type of goods of carrying very many usually, can not make the fixed chassis of a kind of thing for each article.

Summary of the invention

The purpose of this utility model is to provide a kind of various article in the process of stacking, the Horizontal trolley that the height of supporting plate is remained unchanged substantially.

The technical solution of the utility model is: a kind of Horizontal trolley comprises base, is arranged at the below caster wheel of base, connects as one and be positioned at the column of base both sides with base, the back timber that is connected with two column tops; Described column is provided with guide rail, and a connection box is provided with guide wheel, and this guide wheel is positioned at described guide rail, and connection box and supporting plate are fixedly connected; The bottom of main spring is connected on the connection box, and hang on described back timber the upper end of main spring; A plurality of auxilliary springs that are set up in parallel are arranged between described connection box and the back timber, and an end of described auxilliary spring is connected with back timber or connection box, and another end of auxilliary spring is with back timber or connection box is detachable is connected.

Because the utilization of technique scheme, the utility model compared with prior art has following advantage:

Be connected in number between back timber and the connection box by increasing or reduce auxilliary spring, make that the size of the spring force between connection box and the back timber is regulated, then supporting plate can be adapted to piling up of various article, and supporting plate remains on the height of a setting, and the bearer is easy to operate.
