Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting equipment, and in particular relates to an alloy steel combined frog hoisting device. Background Art

[0002] In the railway track maintenance system, the regular replacement and meticulous maintenance of alloy steel combined frogs occupy a vital position. These tasks are not only frequent but also require extremely high safety performance. Traditionally, lifting operations often rely on special rigging such as hooks, wire ropes and chains. However, when dealing with the special shape of rails, the application of these traditional rigging is particularly limited.

[0003] Due to its unique geometric shape, rails are traditionally hoisted by directly binding the slings at both ends of the rails during processing and installation. This hoisting method is not only cumbersome and inefficient, but also has significant safety hazards. Due to the long strip design of the rails, its center of gravity is difficult to control accurately, and the shaking and deviation that may occur during the hoisting process greatly increase the difficulty and risk of the hoisting operation. At the same time, the unstable hoisting state also seriously affects the work efficiency and brings unnecessary challenges to the maintenance of railway tracks. Summary of the invention

[0004] In view of the above shortcomings of the prior art, the utility model provides an alloy steel combined frog hoisting device, which realizes the rapid, stable and safe hoisting of the alloy steel combined frog, and effectively improves the work efficiency and operation safety.

[0005] In order to achieve the above-mentioned purpose and other related purposes, the utility model provides an alloy steel combined frog hoisting device, which is characterized by comprising:

[0006] Rings;

[0007] A clamping mechanism connected to the lifting ring;

[0008] The clamping mechanism includes a left clamping plate, a right clamping plate and a support beam. The left clamping plate and the right clamping plate are symmetrically arranged. A support beam is arranged between the left clamping plate and the right clamping plate. One end of the support beam is hingedly connected to the left clamping plate through a connecting pin, and the other end of the support beam is hingedly connected to the right clamping plate through a connecting pin. Connecting ears are fixedly connected to the upper ends of the opposite sides of the left clamping plate and the right clamping plate, and each connecting ear is connected to a lifting ring.

[0009] In one of the embodiments, hook claws are fixedly connected to the lower ends of the opposite sides of the left clamping plate and the right clamping plate.

[0010] In one embodiment, each of the connecting ears is connected to the hanging ring via a connecting ring.

[0011] In one embodiment, the left clamping plate and the right clamping plate are made of high-strength alloy steel.

[0012] In one of the embodiments, the connecting pin is made of quenched and tempered steel.

[0013] In one embodiment, an annular handle is provided on the top of the left clamping plate and the right clamping plate.

[0014] Compared with the prior art, the utility model provides an alloy steel combined frog hoisting device, which realizes the rapid, stable and safe hoisting of the alloy steel combined frog, and effectively improves the work efficiency and operation safety.

[0015] Through the clamping mechanism, the device can stably and accurately clamp the alloy steel combination switch, effectively solving the problems of difficult center of gravity control, hoisting shaking and deviation caused by the long strip design of the rails in the traditional hoisting method, greatly reducing the safety hazards during the hoisting process and ensuring the safety of the operators.

[0016] The design of the clamping mechanism makes the lifting operation easier and faster. The operator can quickly complete the clamping, lifting and releasing process of the frog without complicated adjustment and binding steps, which significantly shortens the operation time and improves work efficiency.

[0017] The support beam in the clamping mechanism is hingedly connected to the left clamping plate and the right clamping plate through a connecting pin, so that the device can adapt to alloy steel combination frogs of different sizes and shapes. In addition, the design of the hook also further enhances the stability and flexibility of the clamping, ensuring the effective use of the device under different working conditions.

[0018] The left and right clamping plates made of high-strength alloy steel and the connecting pins made of quenched and tempered steel ensure that the lifting device can maintain structural stability and durability when bearing heavy loads.

[0019] The circular handles arranged on the top of the left clamping plate and the right clamping plate provide a convenient operation method for the operator, making the clamping and releasing process more labor-saving and easy to control. BRIEF DESCRIPTION OF THE DRAWINGS

The connecting pin 4 is hingedly connected, and the upper ends of the opposite sides of the left clamping plate 210 and the right clamping plate 220 are fixedly connected with connecting ears 5, each connecting ear 5 is connected to the lifting ring 1, and the support beam 230 is arranged between the left clamping plate 210 and the right clamping plate 220 to play a role of supporting and stabilizing clamping; the two ends of the support beam 230 are respectively hingedly connected to the left clamping plate 210 and the right clamping plate 220 through the connecting pin 4, so that the clamping mechanism can be flexibly adjusted when clamping the frog to adapt to frogs of different sizes and shapes.

[0028] The left clamping plate 210 and the right clamping plate 220 are fixedly connected with hooks 6 at the lower ends of the opposite sides to provide additional fixing force when clamping the frog to prevent the frog from slipping or shifting during the lifting process.

[0029] Each of the connecting ears 5 is connected to the lifting ring 1 through the connecting ring 3, so that the force transmission during the lifting process is more stable and the vibration and impact are reduced.

[0030] The left clamping plate 210 and the right clamping plate 220 are made of high-strength alloy steel to ensure that they can withstand a large load without deformation or breakage during the lifting process.

[0033] Clamping process: The operator first moves the hoisting device to the top of the alloy steel composite frog to be hoisted, and adjusts the relative positions of the left clamping plate 210 and the right clamping plate 220 to make the hook 6 contact and clamp the frog. Then, force is applied through the ring handle 7 to move the left clamping plate 210 and the right clamping plate 220 toward each other until the frog is tightly clamped.

[0034] Hoisting process: After the clamping mechanism 2 firmly clamps the frog, the operator starts the hoisting equipment and lifts the hoisting device together with the frog through the lifting ring 1. During the hoisting process, the connecting ring 3 and the connecting ear 5 smoothly transmit the hoisting force to the clamping mechanism 2, and then from the clamping mechanism 2 to the frog, ensuring the stability and safety of the entire hoisting process.

[0035] Unloading process: When the frog is hoisted to the designated location, the operator operates the clamping mechanism 2 through the annular handle 7 to separate the left clamping plate 210 and the right clamping plate 220 to release the frog. Then, the hoisting device can be moved out to prepare for the next hoisting operation.
