Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe heat treatment equipment, in particular to a supporting and fixing device for steel pipe heat treatment. Background Art

[0002] Heat treatment, as a metal heat processing technology, is mainly based on the process of heating, keeping warm and cooling metal materials in the solid state to achieve the expected organizational and performance goals. This process plays an important role in the field of metal material processing. With the continuous development and progress of society, heat treatment technology is also constantly being updated and improved.

[0003] In recent years, as pipeline design has become more mature, pipeline materials have become higher and higher, and the wall thickness has become thinner and thinner. Compared with thick-walled pipes, thin-walled pipes often have lower roundness. During power station piping, especially heat treatment, thin-walled pipes are further deformed under the action of high temperature environment and their own gravity, and the phenomenon of ovality exceeding tolerance has increased more and more. This situation has a great impact on the quality and performance of pipeline engineering.

[0004] During the assembly process, the pipe mouth cannot be welded due to the non-roundness and large misalignment, or the misalignment exceeds the standard after the welding is completed, and the non-destructive testing cannot pass the acceptance, resulting in an increase in rework. This not only wastes resources and time, but may also have a negative impact on the progress of the project. Utility Model Content

[0075] In this article, a limit plate installation mechanism 260 will be introduced in detail. This mechanism is mainly composed of a slide rail 261, a screw rod 262 and a limit nut 263, which work together to achieve an efficient and stable limit control.

[0076] First, the slide rail 261 is installed at one end of the upper end surface of the bottom plate 101 away from the first limit plate 220. The purpose of this design is to ensure the stability and reliability of the slide rail 261 on the bottom plate 101. The existence of the slide rail 261 provides a linear motion path for the limit plate, making the limit control more precise.

[0077] Next, the lower end surface of the second limit plate 250 is provided with a slide groove that cooperates with the slide rail 261, which is to ensure the smoothness of the limit plate during movement. At the same time, the lower end surface of the second limit plate 250 also has at least two screws 262, which pass through the corresponding positions on the bottom plate 101 and are locked by the limit nut 263. This design not only ensures the stability of the limit plate, but also makes the limit control more precise.

[0078] Now let's look at the design of the bottom plate 101. A long hole 201 is opened on the bottom plate 101 at the position corresponding to the screw rod 262, so that the screw rod 262 can smoothly pass through the bottom plate 101. This design not only improves the convenience of installation, but also provides enough space for the movement of the limit plate.

[0079] In summary, the limit plate installation mechanism 260 realizes accurate and stable limit control through the ingenious design of the slide rail 261, the screw rod 262 and the limit nut 263. Its appearance provides a strong guarantee for the operation of various equipments and greatly improves the service life and operation efficiency of the equipments.

[0080] Further, according to some embodiments of the present invention, the width of the elongated hole 201 matches the outer diameter of the screw rod 262 , and the screw rod 262 is distributed on both sides of the slide groove.

[0081] When further describing the implementation of the present invention, the key feature that the width of the elongated hole 201 matches the outer diameter of the screw 262 is taken as an example. The core of this design concept is to ensure a tight connection between the elongated hole 201 and the screw 262, thereby improving the stability and service life of the overall structure.

[0082] Specifically, the screw rods 262 are evenly distributed on both sides of the slide slot, which is not only conducive to achieving accurate matching between the long hole 201 and the screw rods 262, but also can improve the support strength of the screw rods 262 to a certain extent, making the entire structure more stable.

[0083] On this basis, a series of optimizations are also made to the utility model. First, detailed calculations and simulations are made for the matching relationship between the width of the long hole 201 and the outer diameter of the screw 262 to ensure the best match between the two.

[0084] Secondly, in order to reduce the wear of the screw rod 262 in the chute, the present embodiment adopts a special lubricant and anti-wear measures, so that the service life of the screw rod 262 can be extended while ensuring the structural stability.

[0085] Finally, the present embodiment also considers the reliability of the connection between the long hole 201 and the screw rod 262. In the design process, the present embodiment fully considers various stress conditions in practical applications and adopts corresponding reinforcement measures. In this way, even under extreme conditions, the present invention can maintain good performance.

[0086] Further, according to some embodiments of the utility model, the supporting plate mounting mechanism 230 is composed of a first clamping plate 231 and a second clamping plate 232, the distance between the first clamping plate 231 and the second clamping plate 232 matches the thickness of the supporting plate 240, and first threaded holes 233 are provided at both ends of the first clamping plate 231 and the second clamping plate 232. The lower end of the supporting plate 240 is provided with a second threaded hole 242 corresponding to the position of the first threaded hole 233 of the first clamping plate 231 and the second clamping plate 232, and a bolt 234 is passed through the first threaded hole 233 and the second threaded hole 242 and then fixed by a locking nut 235.

[0087] When further describing the implementation of the present utility model, the present embodiment will take the load-bearing plate mounting mechanism 230 as an example for detailed description. The core components of the load-bearing plate mounting mechanism 230 are the first clamping plate 231 and the second clamping plate 232. The distance between the two and the thickness of the load-bearing plate 240 are carefully designed to ensure the matching degree between them. Such a design enables the load-bearing plate 240 to be stably mounted on the device, avoiding problems such as shaking or loosening caused by thickness mismatch.

[0088] Both ends of the first clamping plate 231 and the second clamping plate 232 are provided with first threaded holes 233, which is to facilitate fixing the bearing plate 240 in the subsequent installation process. At the same time, the lower end of the bearing plate 240 is also designed with a second threaded hole 242 corresponding to the position of the first threaded hole 233 of the first clamping plate 231 and the second clamping plate 232. Such a design allows the bolt 234 to smoothly pass through the first threaded hole 233 and then connect with the second threaded hole 242, so that the bearing plate 240 is firmly fixed on the device through the locking nut 235.

[0089] The advantages of the load-bearing plate installation mechanism 230 are that it can not only ensure the stability of the load-bearing plate 240, but also the installation process is simple and fast, greatly improving the work efficiency. Moreover, since all parts are connected by threads, it is also very convenient to disassemble and replace the load-bearing plate 240. In addition, this design can also effectively protect the load-bearing plate 240 from damage during transportation and installation.

[0090] In summary, the load-bearing plate installation mechanism 230 of the present invention achieves a fast, stable and safe installation effect through the carefully designed first clamping plate 231 and the second clamping plate 232, and the design matching the thickness of the load-bearing plate 240. This design not only improves the work efficiency, but also effectively protects the load-bearing plate 240, making it less likely to be damaged during transportation and installation.

[0091] Further, according to some embodiments of the present invention, there are four groups of the adjustment support plates 360, two groups of the adjustment support plates 360 are respectively arranged on the left and right sides of the jack, and the two groups of the adjustment support plates 360 are placed side by side.

[0092] When further describing the implementation of the utility model, this embodiment is described by taking four groups of adjustment support plates 360 as an example. In the four groups of adjustment support plates 360, each group has two jacks, which are respectively located on the left and right sides thereof. Such a design enables the jacks to be evenly distributed on the adjustment support plates 360, thereby achieving a better support effect.

[0093] The four sets of adjustable support plates 360 are placed side by side to form a stable support system. In practical applications, this layout can improve work efficiency and reduce risks during construction. By reasonably adjusting the positions of the four sets of adjustable support plates 360, it is possible to adapt to different project requirements and ensure smooth construction.

[0094] In addition, in the design of adjusting the support plate 360, this embodiment adopts a humanized structure. During operation, the staff can easily adjust it to meet the needs of various construction scenarios. This design not only improves work efficiency, but also ensures construction safety and reduces the technical requirements for staff.

[0095] In summary, the layout of the adjustable support plates 360 provided by the utility model enables the jack to play a greater role in the construction process. By reasonably arranging four sets of adjustable support plates 360 and placing them side by side, the implementation can achieve efficient support for the project.

[0096] In practical applications, the number and layout of the adjustable support plates 360 can be adjusted according to specific circumstances. For example, the number of adjustable support plates 360 can be increased to improve support stability; the number of adjustable support plates 360 can be appropriately reduced to save space. In addition, the position of the jack can be adjusted according to engineering requirements to achieve the best support effect.

[0097] In summary, the 360-degree adjustable support plate design provided by the utility model is flexible, efficient and safe, and is suitable for various construction scenarios. Whether it is residential, commercial buildings or large-scale infrastructure projects, they can all benefit from it.
