Description

Technical Field

[0001] The utility model belongs to the technical field of heat treatment equipment, in particular to an auxiliary heat treatment furnace bottom roller rotating device. Background Art

[0002] Most of the existing medium and thick plate heat treatment furnaces are roller-bottom heat treatment furnaces, which are widely used in the metallurgical industry. They are mainly used for heat treatment processes such as annealing, normalizing, high-temperature tempering and quenching of steel plates. The main components of the roller-bottom heat treatment furnace include the furnace body steel structure, furnace building materials and operating platform. The main feature of the roller-bottom heat treatment furnace is that there are many horizontal rotating rollers (hearth rollers) at the bottom of the furnace, which drive the furnace charge placed on it to move along the roller table. The furnace charge moves continuously during the heating process and has no fixed contact point with the roller table, so it is heated evenly, without bruises and small deformation.

[0003] After the normalizing process of the roller bottom heat treatment furnace, the surface of the bottom roller is very easy to adhere to fine iron oxide scale, forming "bottom roller nodules", which will cause surface defects such as "pits" on the surface of the steel plate for later heat treatment, causing surface quality problems of the steel plate. Therefore, after the furnace is stopped, when the furnace temperature drops to room temperature, the operator needs to sand each bottom roller on the surface of the steel plate to clean the surface "nodules". Three people are required to perform sanding, lighting, recording and other work in the limited space of the furnace, and another two people are required to shake the rollers by manpower outside the furnace in turn. Although the bottom rollers can be controlled by the operating table to rotate in batches, and the odd and even furnace rollers can be controlled separately in batches, a single roller cannot be specified to rotate independently. If the batch of odd or even furnace rollers rotates, it will cause safety risks in the limited space. The sand roller operation can only manually shake a single bottom roller to rotate. This method is not only labor-intensive but also inefficient, and the bottom roller speed is low (0.5m / min). Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide an auxiliary heat treatment furnace bottom roller rotating device, which is used to solve the technical problem that the prior art relies on manual shaking of the furnace bottom roller to rotate when sanding and cleaning the surface, which is labor-consuming and inefficient.

Changes or adjustments to their relative relationships should be regarded as the scope of the implementation of the present utility model without substantially changing the technical content.

[0027] In existing factories, the process of sanding and cleaning the surface "nodules" of the bottom rollers of heat treatment furnaces is as follows: three people inside the furnace perform sanding, lighting, and recording work in a limited space; two people outside the furnace take turns shaking the rollers to make the internal rollers rotate manually. This method not only consumes manpower but is also inefficient.

[0028] Based on this, the utility model provides an auxiliary heat treatment furnace bottom roller rotation device, please combine Figure 1As shown, it includes: a driving member 10, a speed reducing member 20, a sleeve 30 and a cantilever member 40, wherein the speed reducing member 20 is connected to the output end of the driving member 10; the first end of the sleeve 30 is connected to the speed reducing member 20; the cantilever member 40 is connected to the second end of the sleeve 30, and the cantilever member 40 is provided with a cantilever structure for abutting against the wheel disc of the furnace bottom roller, and a locking member 50 for connecting with the furnace bottom roller, and the cantilever member 40 is driven to rotate by the driving member 10 to drive the furnace bottom roller to rotate. Among them, the driving member 10 is used to provide a power source, the speed reducing member 20 is used to reduce the output speed of the driving member 10 to the required speed, the two ends of the sleeve 30 are respectively connected to the speed reducing member 20 and the cantilever member 40, the cantilever member 40 is used to drive the turntable at the end of the furnace bottom roller to rotate, and the locking member 50 is used to perform circumferential locking with the furnace bottom roller. The cantilever member 40 is driven to rotate by the driving member 10 to drive the furnace bottom roller to rotate, so as to realize the automatic rotation of a single furnace bottom roller, avoid the employees shaking the roller for a long time, greatly reduce the physical exertion of the employees, and also increase the rotation speed of the furnace bottom roller, thereby improving the overall efficiency of the shaking roller operation. In addition, since the device is small and light, it is convenient for one person to move, which further reduces the difficulty of operation and maintenance. Since the device has a simple structure and fewer parts, it is relatively easy to maintain and maintain. The device is controlled automatically, making the operation more convenient and safer. The design of the device allows it to adapt to furnace bottom rollers of different specifications and sizes, and by adjusting the reduction ratio of the reduction member 20, it can meet the requirements of different rotation speeds. In addition, the design of the locking member 50 also enables the device to be circumferentially locked with the furnace bottom roller, ensuring the stability and reliability of the rotation.

[0029] It should be noted that the driving member 10, the speed reducer 20, the sleeve 30 and the cantilever member 40 are coaxially arranged. In this structure, the coaxial arrangement allows the driving member 10, the speed reducer 20, the sleeve 30 and the cantilever member 40 to be arranged in a straight line, thereby reducing the overall size of the device and making the entire device structure more compact, which is conducive to reducing the space occupied by the equipment; the power transmission path is more direct and short, reducing the energy loss in the transmission process. Therefore, this structure helps to improve the transmission efficiency of the device, making the rotation of the furnace bottom roller faster and smoother; it can reduce vibration and noise in the transmission process, thereby improving the stability of the device operation.

[0030] It can be understood that the connection between the driving member 10, the speed reducing member 20, the sleeve 30 and the cantilever member 40 is a detachable connection. This structure can be easily disassembled and replaced. This greatly simplifies the maintenance process and reduces the maintenance cost; the detachable connection makes the device more flexible and adaptable; the assembly and debugging process of each component is simpler and more efficient.

[0031] In some embodiments, when the end of the furnace bottom roller has a wheel disc, the cantilever structure of the cantilever member 40 is used to abut against the three brackets of the wheel disc. Specifically, the cantilever structure abuts against the three brackets on the wheel disc to form a three-point support structure, which is very stable; since the cantilever structure abuts against the three brackets on the wheel disc, the contact area is larger and more evenly distributed, which helps to reduce wear and friction; stable support and reduced friction mean improved transmission efficiency; this design can adapt to wheels of different specifications and sizes, making the device more versatile and adaptable.

[0032] In other embodiments, when there is no wheel disc at the end of the furnace bottom roller, the sleeve 30 is used to be sleeved on the outer side wall of the end of the furnace bottom roller, and the locking member 50 is used to be embedded in the slot in the end of the furnace bottom roller. Specifically, the second end of the sleeve 30 is sleeved on the outer side wall of the end of the furnace bottom roller, so that the sleeve 30 is connected to the furnace bottom roller, and at the same time, the locking member 50 is embedded in the slot at the end of the furnace bottom roller, which increases the stability and reliability of the connection; for the case where there is no wheel disc at the end of the furnace bottom roller, the device can still provide stable rotation support through the double connection of the sleeve 30 and the locking member 50. The design of the sleeve 30 and the locking member 50 is relatively simple, and the installation and disassembly process is also very simple. The operator can quickly connect or disconnect the device with the furnace bottom roller, which improves work efficiency. This design does not require additional processing or modification of the furnace bottom roller to achieve connection with the device, which helps to maintain the integrity and original performance of the furnace bottom roller.

[0033] It should be noted that the cantilever structure of the cantilever member 40 includes a barrel portion 41 and at least three cantilever portions 42 arranged on the peripheral side wall of the barrel portion 41, and each of the cantilever portions 42 is evenly distributed along the circumference of the barrel portion 41 and is in an expanded state in a direction away from the barrel portion 41. Specifically, the design of the cantilever portion 42 enables the cantilever member 40 to have multiple supporting points distributed around the wheel disc when it abuts against the wheel disc of the furnace bottom roller, which increases the contact area between the cantilever member 40 and the wheel disc, thereby improving the stability of the support; since there are multiple cantilever portions 42 evenly distributed along the circumference of the barrel portion 41, these cantilever portions 42 can share and disperse stress together, avoiding the situation of single-point stress concentration; since the cantilever portion 42 is in an expanded state in a direction away from the barrel portion 41, this design can adapt to wheels of different diameters and ensure stable support and transmission, which makes the device have strong adaptability and versatility and can adapt to furnace bottom rollers of different specifications and sizes.

[0034] It can be understood that the locking member 50 is radially penetrated in the barrel portion 41 and is used to lock with the end of the furnace bottom roller. This radial locking method effectively prevents the device from loosening or falling off during the rotation of the furnace bottom roller. The locking member 50 plays a role of radial anti-rotation, increases the connection stability between the device and the furnace bottom roller, and ensures that the device can continuously and stably provide power to the furnace bottom roller. This design also makes the installation and disassembly process simpler, reduces the difficulty of operation, and improves work efficiency. By adjusting the position and number of the locking member 50, it can adapt to furnace bottom rollers of different specifications and requirements, and enhances the versatility and adaptability of the device.

[0035] In the above embodiment, the barrel portion 41 is coaxially arranged with the sleeve 30. The coaxial arrangement enables the barrel portion 41 and the sleeve 30 to have the same axis when rotating, thereby reducing vibration and instability caused by axis deviation.

[0036] Furthermore, the outer diameter of the barrel portion 41 is equal to the outer diameter of the sleeve 30. Since the outer diameters of the barrel portion 41 and the sleeve 30 are equal, it is easier to align and connect the two components during installation and removal, and the compact structural design and reduced vibration help improve transmission efficiency.

[0037] In the above embodiment, the driving member 10 is a motor, the speed reducing member 20 is a speed reducer, and the locking member 50 is a locking nut. Specifically, the driving member 10 can be a low-power motor. In this embodiment, the driving member 10 has a rated power of 0.2kW, a frequency of 50Hz, a rated voltage of 220V / 380V, a rated current of 1.16A / 0.67A, and a speed of 1410r / min; the speed reducing member 20 is a speed reducer, which reduces the high speed of the motor to 0.8-3m / min.

[0038] When the auxiliary heat treatment furnace bottom roller rotating device is used, its use method includes:

[0039] When there is no wheel disc at the end of the furnace bottom roller, the sleeve 30 is sleeved on the outer side wall of the end of the furnace bottom roller, and the locking member 50 is embedded in the slot in the end of the furnace bottom roller; or, when there is a wheel disc at the end of the furnace bottom roller, the cantilever structure of the cantilever member 40 and the three brackets of the wheel disc are mutually supported;

[0040] The driving member 10 is started to drive the furnace bottom roller to rotate.

[0041] Specifically, first, determine which connection method to use according to whether there is a wheel disc at the end of the furnace bottom roller; then, if there is no wheel disc at the end of the furnace bottom roller, sleeve 30 is sleeved on the outer wall of the end of the furnace bottom roller to ensure that the sleeve 30 is in close contact with the furnace bottom roller to provide stable support; the locking member 50 is embedded in the card slot in the end of the furnace bottom roller to ensure that the connection between the sleeve 30 and the furnace bottom roller is firm and reliable, and the locking member 50 plays an anti-rotation role; if there is a wheel disc at the end of the furnace bottom roller, the cantilever structure of the cantilever member 40 and the three brackets of the wheel disc are mutually supported to ensure that the cantilever part 42 is in close contact with the bracket to provide stable support and rotation power for the furnace bottom roller; finally, start the driving member 10 to drive the furnace bottom roller to rotate. The driving member 10 will transmit power to the furnace bottom roller through the reduction member 20, the sleeve 30 and the cantilever member 40 to rotate the furnace bottom roller.

[0042] In summary, the auxiliary heat treatment furnace bottom roller rotating device provided by the utility model drives the cantilever member 40 to rotate through the driving member 10 to drive the furnace bottom roller to rotate, thereby realizing automatic rotation of a single furnace bottom roller, avoiding employees shaking the roller for a long time, which consumes a lot of physical strength, reduces manpower waste, and increases the rotation speed while increasing the roller shaking operation efficiency (the rotation speed is increased from 0-0.5m / min to 0.8-3m / min). The device is small and easy to move by one person.

[0043] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
