Description
Technical field
The present invention relates to transport trolley technology, particularly relate to a kind of technology of elastic lifting formula platform truck.
Background technology
The article-holding cart for stacked items or carrying article is all configured with in a lot of factory, the shelf of these article-holding carts is all fixing, and operating personnel needs to bend to load and unload lower floor's article, thus loads and unloads article very inconvenient, namely have impact on operating efficiency, turn increase labour intensity.
Summary of the invention
For the defect existed in above-mentioned prior art, technical matters to be solved by this invention is to provide a kind of energy convenient working personnel load and unload article, thus can reduce labor intensity, and improves the elastic lifting formula platform truck of operating efficiency.
In order to solve the problems of the technologies described above, a kind of elastic lifting formula platform truck provided by the present invention, comprise base, shelf, the corner, bottom of described base has the castor landed, and base is fixed with a bearing support;
It is characterized in that: described bearing support is provided with two elevating brackets that can slide up and down, and be fixed with the riser guide slided up and down for guiding two elevating brackets, one of them elevating bracket is the first elevating bracket, another elevating bracket is the second elevating bracket, bearing support top is equipped with fixed pulley, fixed pulley is arranged with stay cord, and the two ends of stay cord are separately fixed on two elevating brackets;
Described base is provided with at least one extension spring that can vertically stretch, and the upper end of every root extension spring is all affixed with the first elevator, and lower end is then all affixed with base, and described shelf is fixed on the second elevating bracket.
Further, the top of described bearing support is fixed with one on the first elevating bracket, moves spacing lifting limiting stopper, this lifting limiting stopper is arranged on above the first elevating bracket, and the position being formed and interfere that moves up be laid in the first elevating bracket, when making the first elevating bracket rise to lifting limiting stopper place, lifting limiting stopper can press against the first elevating bracket, thus spacing to the first elevating bracket realization moves.
Elastic lifting formula platform truck provided by the invention, fixed pulley and stay cord is utilized to realize the interlock of two elevating brackets, the elastic force of extension spring is utilized to make the stacked items on shelf remain in the altitude range of a setting, operating personnel adopts conventional stance can load and unload article easily, without the need to bending in handling article process, can reduce labor intensity, improve operating efficiency.
Accompanying drawing explanation
Fig. 1 is the left view of the elastic lifting formula platform truck of the embodiment of the present invention;
Fig. 2 is the back view of the elastic lifting formula platform truck of the embodiment of the present invention.
Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and be described in further detail embodiments of the invention, but the present embodiment is not limited to the present invention, every employing analog structure of the present invention and similar change thereof, all should list protection scope of the present invention in.
As Figure 1-Figure 2, a kind of elastic lifting formula platform truck that the embodiment of the present invention provides, comprise base 1, shelf 3, the corner, bottom of described base 1 has the castor 4 landed, and base 1 is fixed with a bearing support 2;
It is characterized in that: described bearing support 2 is provided with two elevating brackets that can slide up and down 51,52, and be fixed with the riser guide 21 slided up and down for guiding two elevating brackets, one of them elevating bracket 51 is the first elevating bracket, another elevating bracket 52 is the second elevating bracket, bearing support 2 top is equipped with fixed pulley 6, fixed pulley 6 is arranged with stay cord 7, the two ends of stay cord 7 are separately fixed on two elevating brackets 51,52;
Described base 1 is provided with at least one extension spring 8 that can vertically stretch, and the upper end of every root extension spring 8 is all affixed with the first elevator 51, and lower end is then all affixed with base 1, and described shelf 3 is fixed on the second elevating bracket 52.
In the embodiment of the present invention, the top of described bearing support 2 is fixed with one for the first elevating bracket 51 moves spacing lifting limiting stopper 9, this lifting limiting stopper 9 is arranged on above the first elevating bracket 51, and the position being formed and interfere that moves up be laid in the first elevating bracket 51, when making the first elevating bracket rise to lifting limiting stopper place, lifting limiting stopper can press against the first elevating bracket, thus spacing to the first elevating bracket realization moves.
The embodiment of the present invention is used for stacked cargo or transports goods, by adjusting quantity and the elastic force of extension spring, stacked items on shelf can be remained in the altitude range of a setting, make operating personnel adopt conventional stance can load and unload article easily, its principle of work is as follows:
On shelf 3 during stacked items, the weight of stacked items can produce downforce to shelf 3, shelf 3 is forced to move down, second elevating bracket 52 also can move down thereupon, and pull the first elevating bracket 51 by stay cord 7, the elastic force making it to overcome extension spring 8 moves up, until the pulling force of the stacked items downforce and extension spring 8 that act on shelf 3 reaches balance, article stacking on shelf 3 are more, its downforce acting on shelf 3 is also larger, it is more that shelf 3 also declines, therefore extension spring produces pulling force the stacked items on shelf 3 can be allowed to remain in the altitude range of a setting, thus convenient working personnel load and unload article,
When the stacked items weight on shelf 3 exceedes rated weight, the first elevating bracket 51 moves to and withstands lifting limiting stopper 9, thus play buffer protection effect, make shelf to slip down to the end, extension spring also can be avoided to damage.
