Description
Technical Field
[0001] The utility model belongs to the technical field of warehouse stacking equipment, and in particular relates to a lifting frame of a stacking crane used for supporting a lifting track of the stacking crane. Background Art
[0002] At present, with the development of economy, the storage cost is getting higher and higher. In order to make full use of storage space and reduce storage cost, the height of goods stacking in warehouse is getting higher and higher. The corresponding goods stacking must rely on corresponding stacking equipment. Forklift is a common equipment for moving and stacking goods in warehouse. However, the lifting height of forklift is limited, and its stacking height is generally within 3 meters, which leads to the limitation of goods stacking height and waste of storage space in warehouse. Moreover, the turning radius of forklift is large, and sufficient operating space must be left for forklift in the warehouse, which also causes waste of storage space in warehouse.
[0003] The stacking crane is a commonly used stacking equipment for stacking goods in warehouses in recent years. The stacking crane is a lifting track suspended at the lower end of the mobile trolley of the warehouse crane, and a fork frame that can move up and down along the lifting track is arranged on the lifting track. The fork frame is equipped with a fork, and the fork frame and the fork are used to realize the movement of goods at the height of the warehouse, and the crane and the mobile trolley are used to realize the movement of goods in the width and length directions of the warehouse, so as to realize the handling and stacking of goods. For example, the Chinese utility model patent with the patent number "ZL2019217063580" and the name "A stacking crane for a three-dimensional warehouse" discloses a stacking crane in which a column is suspended under the trolley, a T-shaped track is installed on the column, the bearing platform can move up and down along the column, and a bidirectional fork is installed on the bearing platform. However, the existing column is usually a square column steel frame structure, which usually requires four vertically arranged support columns, and multiple horizontal ring beams arranged along the height direction of the support columns and fixedly connected to the four support columns. In order to improve the rigidity and stability of the column, multiple diagonal braces are also required. The columns of this structure have sufficient rigidity and stability, but they are heavy in weight. When moving goods, the mobile trolley must bear not only the weight of the goods, but also the weight of the lifting rails, columns and forks. The excessive weight of the columns increases the useless work of the overhead crane and the mobile trolley when moving, resulting in high energy consumption and high cost of use. Utility Model Content
[0004] To sum up, in order to overcome the shortcomings of the prior art problems, the utility model provides a lifting frame for a stacking crane, which has a supporting steel column arranged parallel to the lifting track on one side of the lifting track of the stacking crane, the supporting steel column and the two lifting tracks are distributed in a triangle, the supporting steel column and the lifting track are fixedly connected by connecting parts, the triangular structure has the best stability, and the rigidity and stability of the lifting track are effectively improved. At the same time, only one supporting steel column is set, which can effectively reduce the dead weight, thereby reducing the weight carried by the mobile trolley of the stacking crane when moving, reducing energy consumption, and reducing costs.
[0005] In order to solve the above technical problems, the technical solution of the utility model is implemented as follows:
[0006] A lifting frame for a stacking crane, comprising:

[0009] A connecting piece connects the support column and the two lifting rails.
[0010] Furthermore, the distance between the support column and the two lifting rails is equal.
[0011] Furthermore, there are multiple connecting members, which are arranged along the height direction of the lifting rails, and the two ends of the connecting members are connected to the outer sides of the two lifting rails, and the middle position of the connecting members is connected to the support column.
[0012] Furthermore, the connecting piece is a steel plate formed by stamping or cutting, and has a symmetrical shape.
[0013] Furthermore, it also includes a reinforcement member, which is located between two adjacent connecting members, connecting the support column and one of the lifting rails, and two reinforcement members are arranged between the two adjacent connecting members, and the two reinforcement members are symmetrically arranged on both sides of the support column.
[0014] Furthermore, the reinforcement member is a triangular diagonal bracing tube, the top angle of which is fixedly connected to the support column, and the two bottom angles of which are fixedly welded to the lifting track on one side of the support column by means of a reinforcing steel plate.
[0015] Furthermore, it also includes a fixing plate, which is fixedly arranged on the upper ends of the two lifting rails and the supporting columns, and the fixing plate is tightly connected to the moving trolley of the stacking crane.
[0016] Furthermore, the two lifting rails are both channel steel rails, and the openings of the two channel steel rails are arranged opposite to each other.
[0017] The beneficial effects of the utility model are:
[0018] 1. The support columns of the utility model and the two lifting rails are distributed in a triangle, and the triangular structure is the most stable. Therefore, after the support columns and the two lifting rails are connected by connecting parts, a triangular prism-shaped steel frame structure is formed, which can effectively improve the stability of the lifting rails, while reducing the number of support columns and reducing the dead weight, thereby reducing the weight carried by the mobile trolley of the stacking crane when moving, reducing energy consumption and reducing costs.
[0019] 2. The utility model is provided with a reinforcement connecting the support column and a single lifting rail. The reinforcement also adopts a triangular structure of an oblique support tube to enhance the supporting effect of the support column on the lifting rail, further improve the rigidity and stability of the lifting rail, reduce the shaking or swinging of the lifting rail caused by the excessive height and the suspension structure, so that the fork can operate stably, thereby improving the stability of the stacking crane.
