Description

Technical Field

[0001] The utility model relates to the technical field of frog hoisting construction, in particular to a frog hoisting device. Background Art

[0002] The frog is set at the intersection of two tracks. When the two rails intersect, the wheels are allowed to cross one rail over the other to change tracks. It is generally divided into fixed frogs used in conventional railways and movable frogs used in high-speed railways.

[0003] After searching, I found a patent application with publication number CN218088617U, titled "A Rail Frog Lifting Device." This application proposes fixed frogs with high-roller combination frogs and high-manganese steel monolithic frogs. Conventional high-manganese steel monolithic frogs are cast in one piece and then cooled before being hoisted onto transport racks. Currently, gantry hoists are commonly used, using cables and clamps to lift the frogs. When unloading, since the frog is very heavy, the hoist cable is prone to shaking during the falling process, making it difficult to ensure the falling speed of the frog, causing the frog to collide greatly with the transport rack, which in turn affects the quality of the frog product. A support rod is set under the lifting part, and the support rod passes through the U-shaped groove opened at the lower end of the lifting part to cooperate with the lifting part. The two ends of the support rod are connected to the hydraulic lifting part. By controlling the height of the support rod, the lifting part can be lifted from the lower end of the lifting part, thereby reducing the falling speed of the frog and protecting the frog. The safety is strong. However, when using this application, it is necessary to lay matching guide rails. When the frog is installed and constructed, the surrounding rails have been laid, and it is difficult to lay matching guide rails. Laying guide rails also increases the workload, resulting in inconvenient installation and use. At the same time, the electric hoist is hoisted by a flexible cable, which requires the staff to frequently disassemble the cable, which is also more troublesome. The cable shaking is also difficult to control, resulting in unstable and reliable lifting, and angle adjustment is also more troublesome. Further improvements can be made.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
