Description

Technical Field

[0001] This utility model relates to the field of furnace body welding technology, specifically to alignment equipment for furnace body welding. Background Technology

[0002] The furnace body consists of a furnace shell, furnace lining, and taphole. The furnace shell is mostly cylindrical or inverted conical, reinforced with horizontal reinforcing rings and horizontal and vertical stiffeners. The taphole trough is made of welded or cast steel plates. When welding the deformed upper and lower furnace bodies, alignment equipment is required to fix the upper and lower furnace bodies together, facilitating the installation of screws and connecting the deformed upper and lower furnace bodies together. The deformed upper and lower furnace bodies are then aligned and shaped.

[0003] Currently, a Chinese patent discloses an electrode cylinder welding alignment device (authorization announcement number CN215034988U). The device involves installing an upper alignment fixture on the upper electrode cylinder and a lower alignment fixture on the lower electrode cylinder. After the upper electrode cylinder is hoisted above the lower electrode cylinder and adjusted until the upper and lower alignment fixtures are basically aligned, the relative positions of the upper and lower alignment fixtures are finely adjusted using an adjusting screw and adjusting nut. This allows the upper and lower electrode cylinders to be aligned for easy welding. The adjustment process is short, the alignment effect is obvious and reliable, and the verticality of the electrode cylinder after welding is within ±2mm. It also eliminates the need to remove the temporary positioning plate. Furthermore, the alignment fixture is easy, quick, and labor-saving to install and replace.

[0004] According to the above reference materials, in the above device, the upper adjusting nut is installed on the upper end of the adjusting screw, and then the lower part of the adjusting screw is passed through the first mounting hole and the second mounting hole and installed together with the lower adjusting nut. Adjusting the upper adjusting nut or the lower adjusting nut respectively makes a fine adjustment to the relative position of the upper alignment fixture or the lower alignment fixture. However, when the furnace body is welded and aligned, the clamping effect of the left pressure block and the right pressure block on the object is not ideal. The upper and lower furnace bodies are prone to slippage, making it inconvenient to clamp and fix the furnace body, thus reducing the alignment effect of the furnace body.

[0005] Based on this, the present invention designs an alignment device for furnace body welding to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an alignment device for welding furnace bodies.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] Alignment equipment for furnace body welding includes a fixed frame with two mounting plates on each side, and a fixing mechanism disposed between the two mounting plates. A clamping plate is mounted on one side of each mounting plate, and limit plates are provided on both sides of each clamping plate. A connecting block is fixedly connected to the rear end of each limit plate, and a fixing block is fixedly connected to the rear end of each connecting block. Both the connecting block and the fixing block are slidably connected to the inner wall of the clamping plate, and a limit component is provided on the outer wall of the fixed frame.

[0009] Furthermore, the fixing mechanism also includes clamping bolts rotatably connected to both sides of the clamping plate, one end of which passes through the clamping plate and is threadedly connected to the center of the fixing block.

[0010] Furthermore, the outer wall of the limiting plate is provided with several evenly arranged limiting grooves.

[0011] Furthermore, two telescopic rods are fixedly connected between the rear end of the fixing block and the clamping plate, and a compression spring is sleeved on the outer wall of the telescopic rod.

[0012] Furthermore, the two telescopic rods are respectively located at both ends of the clamping bolt.

[0013] Furthermore, the limiting component includes a fixing bolt rotatably connected to one side of one of the mounting plates, one end of which passes through both mounting plates and the fixing frame and is threaded with a nut.

[0014] Furthermore, a first washer is provided between one end of the fixing bolt and one of the mounting plates, and a second washer is provided between one end of the nut and the other mounting plate.

[0015] Furthermore, a limiting bolt is installed at one end of the mounting plate, and one end of the limiting bolt penetrates into the inner wall of the clamping plate.

[0016] Beneficial effects

[0017] 1. When welding the exterior of the deformed upper and lower furnace bodies, the fixing frame can clamp and fix the outer walls of the upper and lower furnace bodies through the clamping plate at one end of the mounting plate. The limiting plates and limiting grooves on both sides of the clamping plate cooperate with the stiffening plates on the exterior of the furnace body to increase the friction between the clamping plate and the stiffening plates and improve the clamping effect of the clamping plate. Rotating the clamping bolt and the fixing block can make the connecting block drive the limiting plate to move to one end to clamp the furnace body. One end of the clamping bolt has a fine thread. The telescopic rod and the compression spring can cooperate to provide auxiliary support for the fixing block and reduce the frequency of the clamping block shaking. The upper and lower furnace bodies can be clamped and fixed to keep the furnace body in an aligned state for easy shaping.

[0018] 2. Fixing bolts are installed in the holes at one end of the fixing frame and the mounting plate. The fixing bolts pass through the two mounting plates and the fixing frame in sequence and cooperate with the nuts to fix the position of the mounting plates. The first washer and the second washer can improve the fastening effect of the fixing bolts and nuts on the fixing frame and the mounting plates. The limit bolts cooperate with the nuts to fix the mounting plates and the clamping plates together, fix the clamping plates, improve the clamping stability of the clamping plates on the furnace body, and improve the use effect of the device.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4 Alignment equipment for furnace body welding includes a fixing frame 100, with two mounting plates 200 installed on both sides of the fixing frame 100, and a fixing mechanism 300 disposed between the two mounting plates 200. A clamping plate 310 is installed on one side of the mounting plate 200, and a limit plate 320 is provided on both sides of the clamping plate 310. A connecting block 330 is fixedly connected to the rear end of the limit plate 320, and a fixing block 340 is fixedly connected to the rear end of the connecting block 330. The connecting block 330 and the fixing block 340 are slidably connected to the inner wall of the clamping plate 310, and a limit component 390 is provided on the outer wall of the fixing frame 100.

[0029] It should be noted that the furnace body consists of an upper furnace body, a lower furnace body, a flange, a furnace lining, a triangular plate, and stiffening plates. When welding the deformed upper and lower furnace bodies, if the upper and lower furnace bodies are misaligned, a four-plate furnace body adjuster is needed to clamp and fix them. Screws can be used to connect the outer wall of the furnace body to reduce equipment damage and facilitate the reshaping of the deformed upper and lower furnace bodies. The fixing frame 100, mounting plate 200, and clamping plate 310 can cooperate to form a four-plate furnace body adjuster to clamp and fix the stiffening plates on the outer wall of the furnace body. The fixing frame 100, mounting plate 200, and clamping plate 310 are external independent devices. The clamping bolts 350 cooperate with the connecting block 330 so that the limiting plate 320 can clamp and fix the stiffening plates on the outer wall of the furnace body, aligning and fixing the deformed upper and lower furnace bodies. This device plays an auxiliary role and will not affect the normal connection and reshaping of the upper and lower furnace bodies.

[0030] In some embodiments, such as Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the fixing mechanism 300 further includes clamping bolts 350 rotatably connected to both sides of the clamping plate 310, one end of the clamping bolts 350 passing through the clamping plate 310 and threadedly connected to the middle of the fixing block 340.

[0031] Manually rotate the clamping bolt 350 to connect it with the fixing block 340 by thread. The fixing block 340 drives the limiting plate 320 at one end of the connecting block 330 to move to one end and contact the rib plate, which can clamp and fix the furnace body and keep the upper and lower furnace bodies aligned when connected.

[0032] In this embodiment of the utility model, the outer wall of the limiting plate 320 is provided with several evenly arranged limiting grooves 360.

[0033] When the connecting block 330 drives the limiting groove 360 ​​on the outer wall of the limiting plate 320 to contact the reinforcing plate, the tightness of the connection between the clamping plate 310 and the furnace body can be improved, and the fixing effect of the clamping plate 310 on the upper and lower furnace bodies can be improved.

[0034] In this embodiment of the utility model, two telescopic rods 370 are fixedly connected between the rear end of the fixing block 340 and the clamping plate 310, and a compression spring 380 is sleeved on the outer wall of the telescopic rod 370.

[0035] The telescopic rod 370, in conjunction with the compression spring 380, can provide limiting support for the fixed block 340. The compression spring 380 serves as an energy storage structure, while the telescopic rod 370 acts as a damping structure. This allows the telescopic rod 370 and the compression spring 380 to work together to support the fixed block 340 and reduce the fluctuation frequency of the clamping plate 310.

[0036] In this embodiment of the utility model, two telescopic rods 370 are respectively disposed at both ends of the clamping bolt 350.

[0037] Two telescopic rods 370 and a compression spring 380 are distributed at the upper and lower ends of the clamping bolt 350, which can provide auxiliary support for the clamping bolt 350 and improve the movement effect of the fixing block 340.

[0038] In some embodiments, such as Figure 4 As shown, in a preferred embodiment of the present invention, the limiting component 390 includes a fixing bolt 391 rotatably connected to one side of one of the mounting plates 200. One end of the fixing bolt 391 passes through the two mounting plates 200 and the fixing frame 100 in sequence and is threadedly connected to a nut 392.

[0039] One end of the fixing bolt 391 passes through the holes at both ends of the fixing bracket 100 and the hole at the other end of the mounting plate 200 and is threadedly connected to the nut 392. This allows the two mounting plates 200 to be clamped and fixed to the fixing bracket 100, and provides stable support for the clamping plate 310.

[0040] In this embodiment of the utility model, a first washer 393 is provided between one end of the fixing bolt 391 and one of the mounting plates 200, and a second washer 394 is provided between one end of the nut 392 and the other mounting plate 200.

[0041] The fixing bolt 391 and nut 392 are in contact with the two mounting plates 200 through the first washer 393 and the second washer 394 respectively, which can fasten the fixing frame 100 and the mounting plate 200 and improve the use effect of the device.

[0042] In this embodiment of the utility model, a limiting bolt 395 is installed at one end of the mounting plate 200, and one end of the limiting bolt 395 penetrates into the inner wall of the clamping plate 310.

[0043] One end of the limit bolt 395 passes through the hole at the other end of the mounting plate 200 and the hole on the clamping plate 310 in sequence, and cooperates with the nut to clamp and fix the clamping plate 310, preventing the clamping plate 310 from loosening when fixing the upper and lower furnace bodies.

[0044] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
