Description

Technical Field

[0001] This utility model relates to the field of metallurgical equipment technology, and in particular to a novel quick-change device for a fast heating plate for intermediate cladding. Background Technology

[0002] In the continuous casting process of iron and steel metallurgy, the tundish, as a key container for holding and distributing molten steel, is crucial for ensuring the quality of the molten steel and the smooth operation of production. Therefore, before the casting operation begins, the tundish body usually needs to be fully preheated, or kept warm during the operation interval. This process is often accomplished by a dedicated heating plate.

[0003] Currently, the connection and fixation between the heating plate and the tundish body or its supporting base generally adopts the relatively traditional multi-bolt fastening method. In practice, the heavy heating plate must first be hoisted into place, the multiple bolt holes carefully aligned, and then operators use wrenches and other tools to tighten each bolt one by one. While this fixing method achieves the final connection, its inherent defects are becoming increasingly apparent in high-paced, high-intensity continuous production environments. First, tightening or loosening multiple bolts distributed around the heating plate one by one is time-consuming and cumbersome, directly leading to low heating plate replacement efficiency, extending the tundish turnaround preparation time, and adversely affecting the overall production cycle. Second, under harsh working conditions of high temperature and dust, the labor intensity of operators is high, and multi-bolt fixing is prone to uneven tightening force at various points, which may lead to unstable installation of the heating plate or stress concentration due to thermal expansion and contraction, affecting its service life and heating effect. Furthermore, bolt threads are prone to jamming and rusting at high temperatures; once damaged, repair and replacement are extremely inconvenient, further increasing the difficulty of equipment maintenance and downtime. Therefore, this utility model proposes a novel quick-heating plate replacement device for intermediate packaging to address the shortcomings of the prior art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a novel quick-change device for the intermediate cargo heating plate, which aims to improve the problems of cumbersome and time-consuming installation and fixing process, low replacement efficiency and low fixing reliability of the intermediate cargo heating plate in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides a novel quick-change device for a rapid heating plate of an intermediate package, comprising: a base, a heating plate body, a limiting component, and a fixing component.

[0006] The limiting component includes a mounting plate, a mounting screw, a limiting block, an adjusting screw, and an adjusting knob; the fixing component includes a fixing screw, a first nut, a second nut, a fixing pressure block, and an operating handle.

[0007] Furthermore, the mounting plate is fixed to the base by the mounting screw, the adjusting screw is threaded into the inside of the limiting block, and the adjusting knob is connected to one end of the adjusting screw; the fixing screw is vertically fixed to the base, the fixing block has a round end and is rotatably sleeved on the fixing screw, and the operating handle is fixedly connected to the fixing block.

[0008] Preferably, the head of the mounting screw is provided with a hexagonal groove.

[0009] Preferably, the edge of the heating plate body is provided with a notch that matches the limiting block.

[0010] Preferably, the axis of the adjusting screw is arranged along the radial direction of the heating plate body, and the axis of the adjusting screw points to the center of the heating plate body. Its rotation drives the limiting block to move along the radial direction of the heating plate body.

[0011] Preferably, the axial position of the fixed pressure block is limited between the first nut and the second nut, both of which are threaded onto the fixed screw.

[0012] Preferably, the fixing block rotates around the axis of the fixing screw, so that its round end can selectively press against the top surface of the heating plate body.

[0013] Preferably, the operating handle and the fixed pressure block are fixedly connected.

[0014] Preferably, there are two of each of the limiting component and the fixing component, and they are symmetrically arranged on the base.

[0015] This utility model has the following beneficial effects: 1. This utility model, by setting a fixing assembly consisting of a fixing screw, a fixing block sleeved on the fixing screw, and an operating handle, uses the rotation of the operating handle to drive the fixing block with an eccentric round end to rotate, thereby realizing the rapid pressing or releasing of the heating plate body. This solves the problem in the prior art that the replacement of the heating plate relies on tightening bolts one by one, which is cumbersome and time-consuming. It achieves the technical effect of significantly shortening the installation and disassembly operation time and greatly improving the efficiency of heating plate replacement.

[0016] 2. This utility model, by setting a heating plate body with a notch, a limiting block that cooperates with the notch, and an adjusting screw for lateral tightening, works in conjunction with a fixing component that applies vertical clamping force from above to form a combined clamping structure of precise horizontal positioning and strong vertical locking. This solves the problems of inaccurate heating plate positioning or easy loosening and displacement during high-temperature operation caused by the single fixing method in the prior art, and achieves the technical effects of accurate positioning, firm and reliable clamping, and ensuring the working stability of the heating plate.

[0017] 3. This utility model solves the problems of difficult maintenance, long replacement cycle, and impact on the entire production line after the fixture components (especially vulnerable parts under harsh working conditions) are damaged, by designing the limiting component as an independent module including a mounting plate and a mounting screw, and detachably fixing it to the base by the mounting screw. It achieves the technical effects of modular structure, easy maintenance, quick overall replacement of faulty components, and effective reduction of equipment downtime. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 3This utility model provides a novel quick-change device for intermediate package heating plate, which aims to solve the problems of complex, time-consuming and unstable replacement process of intermediate package heating plate in the prior art.

[0022] The novel intermediate package quick heating plate quick change device includes a base 1, a heating plate body 4, a limiting component 2, and a fixing component 3. The heating plate body 4 is detachably placed on the upper surface of the base 1. The limiting component 2 and the fixing component 3 are both fixedly connected to the base 1 and act on the side and top of the heating plate body 4, respectively.

[0023] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 The limiting component 2 and the fixing component 3 have specific structural features and are installed on the base 1 through specific connection relationships.

[0024] The limiting component 2 includes a mounting plate 204, a mounting screw 205, a limiting block 201, an adjusting screw 202, and an adjusting knob 203. The mounting plate 204 is detachably fixed to the base 1 via the mounting screw 205. The head of the mounting screw 205 has a hexagonal groove 206 for use with external tools for installation and removal. The limiting block 201 is fixedly mounted on the mounting plate 204. The edge of the heating plate body 4 has a notch that matches the shape of the limiting block 201 for initial positioning. The adjusting screw 202 is threadedly connected to the limiting block 201. The axis of the adjusting screw 202 is set along the radial direction of the heating plate body 4. The adjusting knob 203 is fixedly connected to the end of the adjusting screw 202 away from the heating plate body 4. Rotating the adjusting knob 203 can drive the adjusting screw 202 to move axially within the limiting block 201, thereby causing its end to abut against or disengage from the inner wall of the notch in the heating plate body 4.

[0025] The fixing assembly 3 includes a fixing screw 301, a first nut 302, a second nut 303, a fixing block 304, and an operating handle 305. One end of the fixing screw 301 is vertically fixed to the base 1. The fixing block 304 is rotatably fitted onto the fixing screw 301 through its central hole. The first nut 302 and the second nut 303 are both threaded onto the fixing screw 301, and the fixing block 304 is clamped between them in the axial direction. The operating handle 305 and the fixing block 304 are fixedly connected. The fixing block 304 has an eccentrically designed round end. By rotating the operating handle 305, the fixing block 304 can rotate around the axis of the fixing screw 301. Its round end can selectively press against or disengage from the top surface of the heating plate body 4.

[0026] In this embodiment, the limiting component 2 and the fixing component 3 are preferably two in number and are symmetrically arranged on the base 1 about the center of the heating plate body 4 to ensure that the fixing of the heating plate body 4 is more stable and uniform.

[0027] As a preferred embodiment of this utility model, the hexagonal groove 206 on the head of the mounting screw 205 is used to tighten or loosen the screw with a hexagonal wrench, thereby enabling the quick installation or removal of the entire limiting component 2 relative to the base 1, which greatly facilitates the maintenance and repair of the equipment.

[0028] As another preferred option, the notch on the edge of the heating plate body 4, in conjunction with the limiting block 201, not only provides radial positioning but also prevents the heating plate body 4 from rotating in the horizontal plane, ensuring that the heating plate body 4 is placed in a preset precise position.

[0029] As another preferred embodiment, the adjusting screw 202 is arranged radially and threadedly driven with the limiting block 201. The axis of the adjusting screw 202 points to the center of the heating plate body 4. Its rotation drives the limiting block 201 to move radially along the heating plate body 4, so that a precise lateral preload can be easily applied or released to the heating plate body 4 by rotating the adjusting knob 203 to eliminate its wobbling within the limiting block 201.

[0030] As another preferred option, the threaded connection between nut 302 and nut 303 on the fixing screw 301 allows for precise adjustment of the initial height of the fixing block 304 by rotating the two nuts, so that it is flush with the top surface of the heating plate body 4 with different thicknesses or different installation states, thereby ensuring the stroke and clamping force of the subsequent clamping operation.

[0031] As another preferred solution, the round end of the fixed pressure block 304 serves as an eccentric pressure head, and its design of rotating around the axis of the fixed screw 301 enables a rapid switch from the "non-contact" to the "pressing" state, which is the key structure for achieving rapid replacement.

[0032] As another preferred solution, the fixed connection between the operating handle 305 and the fixed pressure block 304 provides the operator with an operating point that is far away from the heating area and easy to apply force. The operator can drive the fixed pressure block 304 to rotate synchronously by turning the operating handle 305.

[0033] Working principle: During operation, the heating plate body 4 is first placed on the base 1, and its edge notch is aligned with the limiting block 201 of the limiting component 2 to complete the initial placement. Then, the adjusting knob 203 of the limiting component 2 is rotated. The adjusting knob 203 drives the adjusting screw 202 to rotate and move axially until its end abuts against the side wall of the heating plate body 4, thereby achieving lateral pre-tightening of the heating plate body 4 and eliminating its wobbling in the horizontal plane. After completing the initial positioning, the operating handle 305 of the fixing component 3 is rotated. The operating handle 305 drives the fixing block 304 fixedly connected to it to rotate around the axis of the fixing screw 301. The eccentric round end of the fixing block 304 will be non-contacted. Rotate the contact position to the clamping position and apply a downward clamping force to the top surface of the heating plate body 4. If a stronger clamping force or fine adjustment is required, tighten the nut 303 below the fixing block 304. At this point, the heating plate body 4 is quickly and securely installed on the base 1. When disassembly is required, the process is reversed. First, loosen the nut 303, then rotate the operating handle 305 in the opposite direction to turn the round end of the fixing block 304 away from the top surface of the heating plate body 4 to release the vertical clamping force. Then, rotate the adjusting knob 203 in the opposite direction to loosen the adjusting screw 202, and the heating plate body 4 can be easily removed from the base 1. The entire installation and disassembly process involves few actions and is short in time, achieving the purpose of quick replacement.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
