Description

Technical Field

[0001] This utility model belongs to the technical field of crystallizer vibration equipment, specifically a fastening device for crystallizer vibration. Background Technology

[0002] In the continuous casting process, the crystallizer is one of the most crucial pieces of equipment. Its main function is to initially solidify molten steel at high temperatures, providing a billet shell with a certain shape and strength for subsequent continuous casting processes. To ensure the smooth progress of the continuous casting process and prevent the billet shell from sticking to the inner wall of the crystallizer, the crystallizer needs to be vibrated. This allows the billet shell to periodically separate and come into contact with the inner wall of the crystallizer, reducing the friction and adhesion between the two and ensuring that the billet shell can move smoothly downwards, thereby improving the stability of continuous casting production and the quality of the cast billet.

[0003] Chinese patent CN201249262Y discloses a full-leaf spring crystallizer vibration guide device and a crystallizer vibration table. It uses four leaf springs arranged around the vibration table as guide plates, which can completely solve the problem of crystallizer vibration sway and ensure the vibration guidance accuracy of the crystallizer during casting production, thereby ensuring normal production and the quality of the cast billet. However, when the crystallizer is installed on the vibration device, it needs to be positioned and tightened. Currently, the positioning and tightening methods in the width direction of the crystallizer are adjusted by adjusting screws and nuts on the movable frame or by tightening the crystallizer with clamping bolts in the vertical direction after manual alignment. This makes positioning and tightening time-consuming and labor-intensive, and the positioning accuracy is low. Furthermore, the vertical clamping method of the crystallizer only uses several sets of bolts and nuts for tightening, and the bolts are prone to loosening or falling off during vibration, which cannot guarantee that the crystallizer is reliably clamped, leading to billet quality problems caused by crystallizer loosening.

[0004] Therefore, there is an urgent need for a fastening device for crystallizer vibration that saves positioning time, reduces complex manual arc adjustment and the adjustment of a large number of bolts and nuts, reduces the labor intensity of operators, ensures the positioning accuracy of the crystallizer in the width direction, and at the same time, can prevent the bolts from loosening or coming off during vibration, thus improving the stability of crystallizer fastening. Utility Model Content

[0005] The purpose of this invention is to provide a fastening device for crystallizer vibration, so as to solve at least one aspect of the problems and defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A fastening device for crystallizer vibration, comprising: A fixed base, wherein a movable frame is provided on the top of the fixed base, and a clamping component is provided at each of the two ends of the top of the movable frame; A crystallizer is provided at the top of the movable frame, and protrusions are provided at both ends of the bottom of the crystallizer. The protrusions are pressed against the sides by the clamping assembly. The movable frame is also provided with a clamping component, which passes through the movable frame and the crystallizer and clamps the upper and lower ends of the crystallizer.

[0007] The fastening device for crystallizer vibration according to the present invention has at least the following technical effects: This crystallizer vibration fastening device can directly tighten the bosses at both ends of the crystallizer through the tightening assembly. Compared with the traditional method of adjusting by adjusting screws and nuts on the movable frame or manual arc adjustment, it greatly saves positioning time, reduces complex manual arc adjustment and a large number of bolt and nut adjustments, reduces the labor intensity of operators, ensures the positioning accuracy of the crystallizer in the width direction, and can limit the lateral displacement of the crystallizer on the movable frame. At the same time, by replacing the bolt tightening method with the clamping assembly, the fastening reliability is enhanced, preventing the bolts from loosening or coming off during vibration, and can limit the longitudinal displacement of the crystallizer during vibration, improving the stability of the crystallizer fastening, thereby ensuring the quality of the cast billet.

[0008] As a further embodiment of this utility model: the clamping assembly includes a positioning block disposed at one end of the top of the movable frame and located on one side of the boss, and a clamping mechanism on the other side of the boss.

[0009] As a further embodiment of this utility model: the tightening mechanism includes a tightening shaft, and the tightening mechanism abuts against one side of the boss through the tightening shaft.

[0010] The clamping assembly includes a positioning block located at one end of the top of the movable frame and on one side of the boss, and a clamping mechanism on the other side of the boss. The clamping mechanism includes a clamping shaft, which abuts against one side of the boss. When the crystallizer is installed on the top of the movable frame, the bottom of the boss is pre-positioned by abutting against the inner side of the positioning block. Then, by extending the clamping shaft of the clamping mechanism, the other side of the boss is clamped, thus restricting the boss between the positioning block and the clamping mechanism. This ensures the installation accuracy of the crystallizer in the lateral direction and reduces positioning errors. It can also effectively resist lateral vibration and impact, prevent the crystallizer from shifting laterally, ensure a tight connection between the crystallizer and the movable frame, and improve the reliability of the fastening.

[0011] As a further improvement of this utility model, the tightening mechanism also includes a self-locking mechanism.

[0012] Since the clamping mechanism also includes a self-locking mechanism, after the clamping mechanism extends the clamping shaft and clamps the boss, the self-locking structure can prevent the clamping mechanism itself from shaking or shifting, avoid the clamping shaft from generating a small clamping force, and ensure that the clamping mechanism always maintains the clamping force on the boss, thereby ensuring that the crystallizer maintains accurate positioning throughout the entire vibration process.

[0013] As a further embodiment of this utility model: the clamping assembly includes a clamping shaft, the top of the clamping shaft is provided with a pin hole, and a pin is provided corresponding to the pin hole.

[0014] As a further embodiment of this utility model: a spring seat is provided in the middle of the clamping shaft, a compression spring is provided inside the spring seat, and one end of the clamping shaft is connected to the top of the base of the spring seat.

[0015] As a further improvement of this utility model, a jack is provided at the bottom of the base of the spring seat.

[0016] The clamping assembly includes a clamping shaft with a pin hole at its top, corresponding to which a pin is inserted. A spring seat is located in the middle of the clamping shaft, containing a compression spring. One end of the clamping shaft is connected to the top of the spring seat's base. A jack is located at the bottom of the spring seat's base. When the crystallizer is installed on top of the movable frame, the clamping shaft passes through the bottom of the movable frame into the crystallizer. At this point, the jack begins to lift, compressing the compression spring and causing the clamping shaft to pass through the top of the crystallizer, inserting the pin into the pin hole at the top of the clamping shaft. When the jack stops lifting and retracts, the rebound force of the compression spring pulls the clamping shaft back, causing the pin to press tightly against the top of the crystallizer, achieving a tight connection between the crystallizer and the movable frame. Compared with the traditional method of relying solely on bolts to press the crystallizer up and down, this greatly shortens the installation time of the crystallizer and allows for longitudinal positioning of the crystallizer, ensuring that the crystallizer and the movable frame always maintain a tight connection. This effectively prevents the crystallizer from loosening or shifting during vibration, ensuring the vibration stability and reliability of the crystallizer.

[0017] As a further improvement of this utility model, a number of buffer components are provided between the fixed base and the movable frame.

[0018] As a further embodiment of this invention: the buffer assembly includes a buffer seat and a buffer spring on top of the buffer seat.

[0019] As a further embodiment of this utility model: the buffer components are arranged around the top of the fixed base, and the number of buffer components is 8-10 sets.

[0020] Because several buffer components are installed between the fixed base and the movable frame, including a buffer seat and a buffer spring on top of the buffer seat, the load distribution of the crystallizer on the vibration device can be more uniform, and the load-bearing capacity of the equipment can be improved without changing the stiffness of the buffer spring. At the same time, the buffer components are installed around the top of the fixed base, with 8 to 10 sets of buffer components, which can better support the movable frame and reduce the left-right and front-back sway during the up-and-down vibration process, thus ensuring the operating accuracy of the equipment.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] like Figure 1-4 The present invention, as shown in the embodiment, provides a fastening device for crystallizer vibration, comprising: a fixed base 1, a movable frame 2 on the top of the fixed base 1, and clamping components 3 on both ends of the top of the movable frame 2; a crystallizer 4 on the top of the movable frame 2, with protrusions 401 on both ends of the bottom of the crystallizer 4, the protrusions 401 being clamped by the clamping components 3 on both sides; and a pressing component 5 on the movable frame 2, which passes through the movable frame 2 and the crystallizer 4 and presses the upper and lower ends of the crystallizer 4.

[0031] In use, when the crystallizer 4 is installed on the vibration device, the movable frame 2 presses the bosses 401 at both ends of the crystallizer 4 with the clamping component 3 to position the crystallizer 4 on the movable frame 2 and restrict its lateral displacement. Then, the clamping component 5 is used to longitudinally fasten the crystallizer 4 on the movable frame 2 to restrict its longitudinal displacement, so that the crystallizer 4 is tightly connected to the movable frame 2, thereby achieving the fastening of the crystallizer 4 on the vibration device.

[0032] Specifically, the fastening device for crystallizer vibration can directly tighten the bosses 401 at both ends of the crystallizer 4 through the tightening component 3. Compared with the traditional method of adjusting by adjusting screws and nuts on the movable frame 2 or manual adjustment, it greatly saves positioning time, reduces complex manual adjustment and a large number of bolt and nut adjustments, reduces the labor intensity of operators, ensures the positioning accuracy of the crystallizer 4 in the width direction, and can limit the lateral displacement of the crystallizer 4 on the movable frame 2. At the same time, by replacing the bolt tightening method with the clamping component, the fastening reliability is enhanced, the loosening or detachment of bolts during vibration is avoided, and the longitudinal displacement of the crystallizer 4 during vibration is limited, improving the stability of the crystallizer fastening, thereby ensuring the quality of the cast billet.

[0033] like Figure 2 As shown, the clamping assembly 3 includes a positioning block 301 disposed at one end of the top of the movable frame 2 and located on one side of the boss 401, and a clamping mechanism 302 on the other side of the boss 401; the clamping mechanism 302 includes a clamping shaft 3021, and the clamping mechanism 302 abuts against one side of the boss 401 through the clamping shaft 3021.

[0034] Specifically, the clamping assembly 3 includes a positioning block 301 located at one end of the top of the movable frame 2 and on one side of the boss 401, and a clamping mechanism 302 on the other side of the boss 401. The clamping mechanism 302 includes a clamping shaft 3021, which abuts against one side of the boss 401. When the crystallizer 4 is installed on the top of the movable frame 2, one side of the boss 401 at the bottom of the crystallizer 4 is pre-positioned by abutting against the inner side of the positioning block 301. Then, by extending the clamping shaft 3021 of the clamping mechanism 302, the other side of the boss 401 is clamped, so that the boss 401 is restricted between the positioning block 301 and the clamping mechanism 302, ensuring the installation accuracy of the crystallizer 4 in the lateral direction and reducing positioning errors. It can also effectively resist lateral vibration and impact, prevent the crystallizer 4 from lateral displacement, ensure the tight connection between the crystallizer 4 and the movable frame 2, and improve the reliability of the fastening.

[0035] Furthermore, the tightening mechanism 302 also includes a self-locking mechanism.

[0036] Specifically, since the clamping mechanism 302 also includes a self-locking mechanism, after the clamping mechanism 302 extends the clamping shaft 3021 and clamps the boss 401, the self-locking structure can prevent the clamping mechanism 302 itself from shaking or shifting, avoid the clamping shaft 3021 from generating a shrinking clamping force, and ensure that the clamping mechanism 302 always maintains the clamping force on the boss 401, thereby ensuring that the crystallizer 4 maintains accurate positioning throughout the entire vibration process.

[0037] According to embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the clamping assembly 5 includes a clamping shaft 501, a pin hole at the top of the clamping shaft 501, and a pin 502 corresponding to the pin hole; a spring seat 503 is provided in the middle of the clamping shaft 501, a compression spring 504 is provided inside the spring seat 503, and one end of the clamping shaft 501 is connected to the top of the base of the spring seat 503; a jack 505 is provided at the bottom of the base of the spring seat 503.

[0038] Specifically, the clamping assembly 5 includes a clamping shaft 501, with a pin hole at the top and a corresponding pin 502. A spring seat 503 is located in the middle of the clamping shaft 501, and a compression spring 504 is installed inside the spring seat 503. One end of the clamping shaft 501 is connected to the top of the base of the spring seat 503. A jack 505 is located at the bottom of the base of the spring seat 503. When the crystallizer 4 is installed on top of the movable frame 2, the clamping shaft 501 passes through the bottom of the movable frame 2 into the crystallizer 4. At this time, the jack 505 begins to lift, compressing the compression spring 504 and causing the clamping shaft 501 to pass through the top of the crystallizer 4. The pin 502 is inserted into the pin hole at the top of the clamping shaft 501. At this time, the jack 505 stops lifting and retracts. The rebound force of the compression spring 504 pulls the clamping shaft 501 back, so that the pin 502 is tightly pressed against the top of the crystallizer 4, realizing a tight connection between the crystallizer 4 and the movable frame 2. Compared with the traditional method of relying solely on bolts to press the crystallizer 4 in the upper and lower directions, this greatly shortens the installation time of the crystallizer 4 and can also limit the longitudinal movement of the crystallizer 4, ensuring that the crystallizer 4 and the movable frame 2 always maintain a tight connection, effectively preventing the crystallizer 4 from loosening or shifting during vibration, and ensuring the vibration stability and reliability of the crystallizer 4.

[0039] According to embodiments of the present invention, such as Figure 1 As shown, a number of buffer components 6 are provided between the fixed base 1 and the movable frame 2; the buffer component 6 includes a buffer seat 601 and a buffer spring 602 on the top of the buffer seat 601; the buffer components 6 are arranged around the top of the fixed base 1, and the number of buffer components 6 is 8-10.

[0040] Specifically, since several buffer components 6 are provided between the fixed base 1 and the movable frame 2, the buffer components 6 include a buffer seat 601 and a buffer spring 602 on the top of the buffer seat 601. This can make the load distribution of the crystallizer 4 on the vibration device more uniform, and can improve the load-bearing capacity of the equipment without changing the stiffness of the buffer spring 602. At the same time, the buffer components 6 are arranged around the top of the fixed base 1, and the number of buffer components 6 is 8-10 sets, which can better support the movable frame 2, so that the left and right lateral swing and front and back lateral swing of the movable frame 2 during the up and down vibration process are smaller, ensuring the operating accuracy of the equipment.

[0041] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
