Description

Technical Field

[0001] This utility model relates to the technical field of hot blast stove overhead crane traveling wheels, specifically a wear-resistant and reinforced device for hot blast stove overhead crane traveling wheels. Background Technology

[0002] Hot blast stove overhead cranes are mostly used for material transfer and other operations. During the operation of hot blast stove overhead cranes, the traveling wheels are prone to wear, deformation, or even failure due to long-term bearing of the crane's own weight and load, frequent friction with the track, and impact loads during start-up and braking. This not only affects the stability of the crane's operation but may also cause safety hazards. Therefore, wear-resistant reinforcement devices for the traveling wheels of hot blast stove overhead cranes are essential.

[0003] However, existing technologies still have many defects in some similar structures when used in practice. For example, the deviation of the traveling wheels can cause the crane to lose control of its running trajectory. If the deviation is serious, it may derail, which will not only damage the equipment but also endanger the safety of surrounding personnel. At the same time, the rotation accuracy will decrease after the guide wheels wear out. If the life of the guide wheels cannot be extended, frequent shutdowns and replacements will be required, which will indirectly cause production losses.

[0004] To address the aforementioned problems, the inventors proposed a wear-resistant reinforcement device for the traveling wheels of a hot blast stove crane. Utility Model Content

[0005] To address the problems of inconvenience in reinforcing the traveling wheels to prevent deviation and inconvenience in extending the service life of the guide wheels, the purpose of this utility model is to provide a wear-resistant reinforcement device for the traveling wheels of a hot blast furnace crane.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a wear-resistant and reinforced device for the traveling wheels of a hot blast furnace crane, comprising symmetrically distributed slide rails, a sliding assembly provided on the outer surface of the slide rails, the sliding assembly comprising symmetrically distributed connecting plates, a plurality of equally spaced support plates fixedly connected between the connecting plates, a fixed frame fixedly connected to the bottom surface of the connecting plates, a first rotating shaft movably passing through the upper part of the fixed frame, a first guide wheel fixedly sleeved on the outer surface of the first rotating shaft, a second rotating shaft symmetrically fixedly connected to the inner wall of one side of the fixed frame, and a second guide wheel rotatably connected to the end of the second rotating shaft.

[0007] As a preferred technical solution of this application, the first guide wheel and the second guide wheel are provided with an anti-wear layer inside. A polymer material layer is fixedly connected to one side of the anti-wear layer, a medium carbon alloy layer is fixedly connected to one side of the polymer material layer, and a high chromium casting layer is fixedly connected to one side of the medium carbon alloy layer.

[0008] Through the above technical solution, the anti-wear layer, polymer material layer, medium carbon alloy layer and high chromium casting layer inside the first guide wheel and the second guide wheel work together to play a wear-resistant and reinforcing role. The high chromium casting layer has high hardness and directly contacts the friction parts to improve wear resistance. The medium carbon alloy layer ensures the strength and toughness of the wheel structure and avoids overall brittle fracture. The polymer material layer reduces friction loss and buffers impact. The anti-wear layer further reduces internal wear, which can effectively extend the service life of the guide wheel.

[0009] As a preferred technical solution of this application, the slide rail is I-shaped.

[0010] Through the above technical solution, the slide rail is I-shaped to provide guidance and support for the movement of the sliding component.

[0011] As a preferred technical solution of this application, the outer surface of the first rotating shaft is in contact with the top surface of the slide rail.

[0012] The above technical solution allows the device to roll along the top surface of the slide rail during movement, thus providing main support and guidance.

[0013] As a preferred technical solution of this application, one side of the first guide wheel is in contact with the upper part of the slide rail.

[0014] With the above technical solution, the first guide wheel slides more stably.

[0015] As a preferred technical solution of this application, the outer surface of the second guide wheel is in contact with the lower inner wall of the slide rail.

[0016] The above technical solutions help guide and enhance the stability of the sliding component and the slide rail.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model can roll along the top surface and upper part of the slide rail during movement, and undertake the main support and guidance functions. The second rotating shaft fixes the second guide wheel. The outer surface of the second guide wheel is in contact with the lower inner wall of the slide rail, which helps to guide and enhance the stability of the sliding component and the slide rail, thereby achieving the purpose of reinforcing the movement of the wheel and preventing deviation.

[0019] 2. This utility model can effectively extend the service life of the guide wheel by using a high-chromium casting layer with high hardness to directly contact the friction parts and improve wear resistance, a medium carbon alloy layer to ensure the strength and toughness of the wheel structure and avoid overall brittle fracture, a polymer material layer to reduce friction loss and buffer impact, and an anti-wear layer to further reduce internal wear.

[0029] When the device moves, it rolls along the top surface and upper part of the slide rail 1, undertaking the main support and guiding role.

[0031] The working principle of the wear-resistant reinforcement device for the traveling wheel of the hot blast stove trolley in this embodiment is as follows: the sliding component 2 and the slide rail 1 cooperate to realize the traveling function. The slide rail 1 is I-shaped and provides guidance and support for the movement of the sliding component 2.
