Description

Technical Field

[0001] The utility model is applied to the technical field of material cart positioning, and particularly relates to a material cart supporting and positioning mechanism. Background Art

[0002] The material cart needs to be positioned in different directions during loading and unloading of the material cart. When the material cart is loaded with fine materials, it is necessary not only to position the material cart in various directions of movement, but also to position the material cart in the vertical direction to prevent the material cart from vibrating and deviating during loading and unloading. At present, the material cart is mainly lifted and placed on the height limit mechanism manually. This method has high labor cost. When the material is heavy, the material cart cannot be lifted. After loading and unloading, the material cart needs to be handled, which is inefficient and can easily cause the cart to deviate and cause the material to fall. Alternatively, the material cart is lifted by a cylinder to drive a support plate. After the material cart moves to a specified position, the cylinder is moved to the bottom of the material cart by an external mechanism for lifting. This method is complicated to operate, and the support plate cannot accurately position the bottom of the material cart, which is prone to deviation and causes the material cart to fall off. In addition, the setting of an external mechanism increases the floor space, and is not highly applicable to the cart. If a material cart supporting and positioning mechanism with a simple structure, stable performance, and the ability to accurately position the material cart and stably lift the material cart can be designed, the above problems can be solved.
