Description

Technical Field

[0001] This utility model relates to the field of cantilever roller technology, and more specifically, to a high-stability, high-temperature resistant cantilever roller structure. Background Technology

[0002] Cantilever rollers are widely used in various industrial production scenarios, especially in industries such as metallurgy, mining, and building materials. As an important support and conveying component, they play a key role in the conveying and processing of materials and the smooth operation of the production process.

[0003] However, traditional cantilever roller structures suffer from numerous problems under high-temperature environments. For example, their high coefficient of thermal expansion easily leads to roller deformation, affecting stability and accuracy. Furthermore, under high loads and high temperatures, cantilever rollers are prone to insufficient torsional and bending resistance, thus impacting service life and operational reliability. Additionally, when the roller tilts, traditional cantilever roller structures lack effective angle adjustment capabilities, making it difficult to quickly return to the normal operating angle, thus reducing the adaptability and reliability of the equipment. To address these issues, this device was invented. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a high-stability, high-temperature resistant cantilever roller structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-stability, high-temperature resistant cantilever roller structure, comprising:

[0006] The roller includes a core shaft and a heat insulation layer covering the core shaft. The core shaft has a hollow structure and is filled with high-temperature resistant ceramic particles. Reinforcing ribs are fixedly installed in the hollow part of the core shaft.

[0007] Roller sleeve, which is fitted onto the roller shaft;

[0008] The support base is used to support the roller shaft. There are two sets of support bases, including a base frame, a protective frame, a cylinder, a pad plate, a frame plate, and a bearing seat. The piston rod end of the cylinder is fixedly connected to the bottom of the pad plate. A support is fixedly installed on the top of the pad plate, and a bracket is fixedly installed on the bottom of the frame plate. The support and the bracket are hinged. The bearing seat is fixedly installed on the top of the frame plate. Both ends of the roller shaft are connected to the bearing seats on both sides respectively.

[0009] Furthermore, the mandrel is made of high-temperature resistant alloy material.

[0010] Furthermore, the heat insulation layer is made of high-temperature resistant ceramic fiber material and is connected to the mandrel by a high-temperature adhesive.

[0011] Furthermore, the high-temperature resistant ceramic particles have a particle size of 1-3 mm and a filling rate of 50%-70% of the internal space of the mandrel.

[0012] Furthermore, the reinforcing ribs are made of high-temperature resistant alloy, with a thickness of 2-5mm and a spacing of 10-20mm.

[0013] Furthermore, the roller sleeve includes an inner layer and an outer layer. The inner layer is made of a high-nickel alloy material, and the outer layer is made of a high-temperature and wear-resistant ceramic material. The inner and outer layers are connected by welding.

[0014] Furthermore, the protective frame of the support base is fixedly installed on the top of the base frame, and the cylinder is set inside the protective frame.

[0015] Furthermore, the high-stability, high-temperature resistant cantilever roller structure also includes a cooling device, which includes a water inlet pipe and a nozzle. The nozzle is angled toward the roller sleeve, and the outer surface of the roller sleeve is provided with a spiral guide groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, the mandrel has a hollow structure filled with high-temperature resistant ceramic particles. This design effectively reduces the coefficient of thermal expansion of the roller and improves its resistance to thermal shock, further enhancing the stability of the roller. A spiral reinforcing rib is fixedly installed in the hollow part of the mandrel, which improves the roller's torsional and bending resistance, enhancing its overall stability and enabling it to maintain good working condition under high load and high temperature environments. The support base, through the cooperation of components such as cylinders, pads, supports, brackets, and frame plates, realizes the roller angle adjustment function. When the roller tilts, the operator can adjust the cylinder at the corresponding position according to the tilt angle to restore the roller to its normal working angle, improving the adaptability and reliability of the equipment.

[0025] The following specific embodiments illustrate the implementation of this utility model.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] See attached document Figures 1-4 The embodiment of a high-stability, high-temperature resistant cantilever roller structure includes a roller shaft 1, a roller sleeve 2, a support seat 3, and a cooling device 4. The roller sleeve 2 is fitted onto the roller shaft 1, the support seat 3 is used to support the roller shaft 1, and the cooling device 4 is used to cool the roller shaft 1 and the roller sleeve 2.

[0028] See attached document Figure 3 and Figure 4 The roller 1 includes a core shaft 101 and a heat insulation layer covering the core shaft 101. The core shaft 101 and the heat insulation layer are connected by a high-temperature adhesive. The heat insulation layer is made of high-temperature resistant ceramic fiber material. This heat insulation layer can effectively prevent heat from being transferred to the core shaft 101, reduce the thermal deformation of the core shaft 101, and improve the overall stability of the roller 1.

[0029] Furthermore, the mandrel 101 has a hollow structure and is filled with high-temperature resistant ceramic particles with a particle size of 1-3 mm. The filling rate is 50%-70% of the internal space of the mandrel 101. The ceramic particle filling design can effectively reduce the thermal expansion coefficient of the roller 1 and improve its thermal shock resistance.

[0030] A reinforcing rib 102 is fixedly installed in the hollow part of the mandrel 101. The reinforcing rib 102 has a spiral structure and is made of high temperature resistant alloy with a thickness of 2-5 mm and a spacing of 10-20 mm. The reinforcing rib 102 can improve the torsional and bending resistance of the roller 1 and enhance its overall stability.

[0031] The roller sleeve 2 includes an inner layer and an outer layer. The inner layer is made of high-nickel alloy material, which has good high temperature resistance and strength. The outer layer is made of high temperature and wear-resistant ceramic material, which has excellent wear resistance and high temperature resistance. The inner and outer layers are connected by welding to ensure the bonding strength between them and improve the overall performance of the roller sleeve 2.

[0032] See attached document Figure 1 and Figure 2 The support base 3 is provided in two sets, including a base frame 301, a protective frame 302, a cylinder 303, a pad 304, a frame plate 305, and a bearing seat 306. The protective frame 302 is fixedly installed on the top of the base frame 301. The cylinder 303 is located inside the protective frame 302. The protective frame 302 can protect the cylinder 303 and other components from interference and damage from the external environment, thereby improving the reliability and service life of the entire support base 3. The piston rod end of the cylinder 303 is fixedly connected to the bottom of the pad 304. A support 307 is fixedly installed on the top of the pad 304. A bracket 308 is fixedly installed on the bottom of the frame plate 305. The support 307 and the bracket 308 are hinged. The bearing seat 306 is fixedly installed on the top of the frame plate 305. The two ends of the roller 1 are respectively connected to the bearing seats 306 on both sides. When the roller 1 is tilted during use, the operator adjusts the cylinder 303 at the corresponding position according to the tilt angle. During this process, the operator opens the cylinder 303, and the piston rod of the cylinder 303 extends or retracts. Since the support 307 at the top of the pad 304 and the bracket 308 at the bottom of the frame 305 are hinged, the angle of the roller 1 can be adjusted.

[0033] It should be noted that the bearing is a high-temperature ceramic bearing with an operating temperature range of -50℃ to 1000℃, which can withstand high temperatures and loads.

[0034] See attached document Figure 2 Both sides of the support base 3 are equipped with water inlet pipes 401, which are connected to an external water source (such as a faucet). The inner end of the water inlet pipe 401 is connected to a nozzle 402, which is set at an angle towards the roller sleeve 2. Cooling water is sprayed out from the nozzle 402 to cool the roller sleeve 2 and help reduce the surface temperature of the roller sleeve 2. The outer surface of the roller sleeve 2 is provided with a spiral guide groove 5 to guide the flow of cooling water and improve the uniformity of cooling. This cooling method can help reduce the temperature of the roller sleeve 2 in high-temperature environments and extend its service life.

[0035] In the technical solution adopted in this embodiment, the mandrel 101 is a hollow structure filled with high-temperature resistant ceramic particles. This design can effectively reduce the thermal expansion coefficient of the roller 1, while improving its thermal shock resistance and further enhancing the stability of the roller 1. The hollow part of the mandrel 101 is fixedly equipped with a spiral reinforcing rib 102. The reinforcing rib 102 can improve the torsional and bending resistance of the roller 1, enhance its overall stability, and enable it to maintain a good working condition under high load and high temperature environments. The support base 3 realizes the function of adjusting the angle of the roller 1 through the cooperation of components such as cylinder 303, pad 304, support 307, bracket 308 and frame plate 305. When the roller 1 tilts, the operator can adjust the cylinder 303 at the corresponding position according to the tilt angle to restore the roller 1 to the normal working angle, thereby improving the adaptability and reliability of the equipment.

[0036] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
