[0002] As an industrial transport vehicle, a forklift plays an important role in the enterprise's logistics system and is the main force in material handling equipment, widely used in various departments such as stations, ports, airports, factories, warehouses, etc. The forklift mast is mainly composed of inner and outer masts; when the mast is used for fork-lifting goods and lifting operations, a large tipping moment is generated with the front axle as the moment center. Therefore, the forklift mast is the most important force-bearing component during the forklift's operation and is also the main load-bearing structure of the forklift's goods-taking device. The forklift mast channel steel is the working force-bearing component of the forklift mast, and its stability directly affects the service life of the mast. It has high requirements for strength, toughness, and dimensional accuracy. The profiled steels applicable to forklift masts include hot-rolled C-shaped, H-shaped, and J-shaped. Among them, the C-shaped profiled steel includes a web and a pair of flange plates.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A C-shaped forklift mast profiled steel includes a web and flange plates. The two ends of the web are connected with flange plates. A connection outer angle is formed at the connection between the web and the flange plates. A groove is provided at the center of the bottom end of the web. The bottom end of the web is located on both sides of the groove and close to the connection of the two flange plates to form a boss, and the side of the boss adjacent to the groove has a smooth transition. A limit guide groove for auxiliary sliding limit of the pulley is provided on the inner wall of the groove.

[0008] As a preferred scheme of the utility model, there are two flange plates in total, and the two flange plates are parallel to each other and perpendicular to the web respectively.

[0009] As a preferred solution of the present utility model, the web and the two flange plates are integrally formed, and the cross-section formed by the web and the two flange plates is C-shaped.

[0010] As a preferred solution of the present utility model, a first rounded corner is provided on the outer side of the bottom end of the flange plate, and a second rounded corner is provided on the inner side of the bottom end of the flange plate.

[0011] As a preferred solution of the present utility model, there are two connection outer corners in total.

[0012] Beneficial effects: Aiming at the problem that the C-shaped forklift mast section steel in the prior art does not have a safety arc chamfer structure and a limit guiding structure, which cannot make the C-shaped forklift mast section steel be safely applied, and at the same time cannot ensure the smooth operation of the roller and the friction period between the roller and the section steel, affecting the stability and service life of the forklift. In the present utility model, by setting the web and the two flange plates to be integrally formed, and the cross-section formed by the web and the two flange plates is C-shaped, a first rounded corner is provided on the outer side of the bottom end of the flange plate, and a second rounded corner is provided on the inner side of the bottom end of the flange plate. The arc chamfer structure on the outer side of the web and the two flange plates makes the C-shaped forklift mast section steel easy to be safely applied. At the same time, by setting the bottom end of the web to be located on both sides of the groove and close to the connection of the two flange plates to form a boss, and the side of the boss adjacent to the groove is smoothly transitioned, and a limit guiding groove for auxiliary sliding limit of the pulley is provided on the inner wall of the groove. The limit guiding ensures the smooth operation of the roller, and prolongs the friction period between the roller and the section steel, improves the stability and service life of the forklift, and reduces the production cost, improves the economic efficiency of forklift use. The overall structure is simple and has a safety arc chamfer structure and a limit guiding structure, making the C-shaped forklift mast section steel easy to be safely applied, ensuring the smooth operation of the roller at the same time, prolonging the friction period between the roller and the section steel, improving the stability and service life of the forklift, reducing the production cost, and improving the economic efficiency of forklift use, which is very practical.
