Technical Field

[0001] This invention relates to the field of welding fixture technology, specifically to a welding fixture for assembling grate plates in a grate cooler. Background Technology

[0002] The application of intelligent welding in the assembly welding of grate plates in grate coolers has significantly improved the manufacturing quality and efficiency of this key cement equipment component. Through a high-precision vision sensing and adaptive control system, intelligent welding can identify misalignment and gaps in grate plate assembly in real time, automatically plan the welding path and dynamically adjust parameters to ensure that the weld maintains uniform penetration and good shape in all positions during welding.

[0003] The invention patent with publication number CN114515928A discloses a welding fixture for assembling grate plates in a grate cooler. This fixture enables direct positioning and automatic fixing of the grate plates during installation, saving operators time. However, the bottom weld of the grate plate is supported or fixed, which restricts the free expansion and contraction of the grate plate during heating or cooling, leading to local deformation of the grate plate. Summary of the Invention

[0004] To overcome the problem that the free expansion and contraction of the grate plate during heating or cooling is constrained when the bottom weld joint is supported or fixed, leading to local deformation of the grate plate, this invention provides a welding fixture for assembling grate plates in a grate cooler, including a frame and further comprising: Slide rails installed on the frame; A sliding frame connected to the slide rail and a connecting plate disposed on the sliding frame; The moving mechanism mounted on the connecting plate includes a first slide groove inside the connecting plate, an electric push plate mounted on the connecting plate, and a sliding frame connected to the telescopic end of the electric push plate. The electric push plate is used to drive the sliding frame to move inside the first slide groove.

[0005] Preferably, it further includes: Connection platform installed on the frame; The module is slidably connected to the connecting platform, and the welding gun is connected to the module.

[0006] Preferably, the moving mechanism further includes: Springs mounted on the sliding frame and lifting components connected to the springs; A second slide groove formed inside the sliding frame and a magnetic sheet installed inside the second slide groove; The first channel is located inside the connecting plate, and the second channel is located inside the sliding frame.

[0007] Preferably, the moving mechanism further includes: The first push rod is installed on the outside of the sliding frame; The connector is installed on the telescopic end of the first push rod.

[0008] Preferably, the moving mechanism further includes: A support rod is mounted on the connector, and the support rod passes through the interior of the sliding frame; The contact block is located at the end of the support rod away from the connector and is used to contact the fixed grate.

[0009] Preferably, the lifting assembly includes: The top plate is installed at the end of the spring away from the sliding frame; The central rod installed inside the top plate and the lifting frame connected to the end of the central rod away from the top plate; The outer ring fitted around the center rod and the risk control components connected to the outer ring.

[0010] Preferably, the lifting assembly further includes: The mounting block is slidably connected to the lifting frame, and the locking strip is set in the mounting block. The locking strip is used to block the grate gaps. A first connecting rod is disposed on the outside of the mounting block, and the first connecting rod passes through the interior of the lifting frame; A connecting bracket installed on the outside of the first connecting rod.

[0011] Preferably, the risk control component includes: The second push rod and telescopic rod are installed outside the outer ring; A connecting box is provided on the telescopic end of the second push rod. The connecting box is connected to the telescopic rod. During the operation of the second push rod, the telescopic rod moves with the connecting box and undergoes corresponding telescopic changes. The first and second through holes are located inside the connector box, through which debris enters the connector box.

[0012] Preferably, the risk control component further includes: The vertical tube installed above the connection box and the connecting ball connected to the vertical tube; The second connecting rod and the filter plate connected to the second connecting rod are installed inside the connecting ball. The filter plate is used to intercept most of the debris.

[0013] This invention provides a welding fixture for grate plate assemblies in a grate cooler. It has the following advantages: 1. The grate plate assembly of this grate cooler uses a welding fixture with a moving mechanism to adjust the position of the grate plates. In existing equipment, the welded area at the bottom of the grate plate is supported or fixed, which restricts the free expansion and contraction of the grate plate during heating or cooling, leading to localized deformation. Therefore, a sliding frame that moves the grate plate in the connecting plate's position is installed to allow the welded end of the grate plate to protrude beyond the connecting plate, thus avoiding the support or fixation at the bottom of the grate plate and solving the aforementioned problem.

[0014] 2. The grate plate assembly welding fixture of this grate cooler uses a moving mechanism to limit the position of the grate plate and grate seams. Two sets of contact blocks within the sliding frame clamp and fix the grate plate at positions where welding is not required, thus limiting the overall position of the grate plate. A lifting assembly further blocks and protects the grate seams, ensuring proper positioning and sealing of the grate plate and seams before welding.

[0015] 3. The grate plate assembly welding fixture of this grate cooler, through the installation of a lifting component, uses a connecting frame to move the first connecting rod, mounting block, and locking strip horizontally, aligning the locking strip with the grate seam position. By adjusting the position of the lifting frame and the locking strip, the lifting frame covers the grate plate, positioning the locking strip within the grate seam. This covers and protects the areas of the grate plate that do not require welding and blocks the grate seam, preventing welding debris from entering from above and becoming difficult to handle.

[0016] 4. The grate cooler's grate plate assembly welding fixture, equipped with a wind control component, sucks up debris from the weld joints and above the grate plates. By creating first and second through holes on the bottom and sides of the arc-shaped box, debris can be sucked up at close range from the weld joints and from above the grate plates as the arc-shaped box deflects or moves horizontally. Connecting balls, a second connecting rod, and filter plates further intercept large amounts of debris. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] like Figures 1-10 As shown, the present invention provides a technical solution: the welding fixture for a grate cooler grate plate assembly is described below.

[0021] Including frame 1, it also includes: The slide rail 2 is installed on the frame 1. There are two slide rails 2, which are arranged symmetrically. The sliding frame 7, which is slidably connected to the slide rail 2, and the connecting plate 8, which is set on the sliding frame 7, are driven by the electric push rod on the slide rail 2 to move the sliding frame 7 on the slide rail 2, thereby controlling the moving mechanism 3 and the grate plate to be in the welding area or the loading and unloading area. The moving mechanism 3 is installed on the connecting plate 8. The moving mechanism 3 includes a first slide groove 301 opened inside the connecting plate 8, an electric push plate 314 installed on the connecting plate 8, and a sliding frame 302 connected to the telescopic end of the electric push plate 314. The electric push plate 314 is used to drive the sliding frame 302 to move inside the first slide groove 301. The electric push plate 314 is composed of an electric push rod and a plate in the horizontal direction. Connecting platform 4 is installed on frame 1; The module 5 is slidably connected to the connecting platform 4, and the welding gun 6 is connected to the module 5. The module 5 is used to drive the movement of the welding gun 6 and the welding work.

[0022] Before using the equipment, manually place the two grates to be welded into the two moving mechanisms 3 respectively, and use the moving mechanisms 3 to limit the position of the grates. Then, according to the required welding spacing of the grates, adjust the two sliding frames 302 and the relative distance between the two grates by simultaneously adjusting the two electric push plates 314. Then, adjust the moving mechanisms 3 and the module 5, and use the welding gun 6 to complete the assembly welding of the grates.

[0023] The mobile mechanism 3 also includes: Spring 303 and lifting assembly 304 connected to spring 303 are mounted on sliding frame 302; A second slide groove 306 is formed inside the slide frame 302 and a magnetic sheet 307 is installed inside the second slide groove 306; A first channel 308 is formed inside the connecting plate 8 and a second channel 309 is formed inside the sliding frame 302; The first push rod 310 is installed on the outside of the sliding frame 302 and is configured as an electric push rod. Connector 311 is provided on the telescopic end of the first push rod 310; The support rod 312 is installed on the connector 311 and passes through the interior of the sliding frame 302; Contact block 313 is located at the end of support rod 312 away from connector 311.

[0024] The process of using the moving mechanism 3 to limit the grate plate: Manually place the grate plate on the connecting plate 8, with one end of the grate plate in contact with the inner wall of the sliding frame 302. At the same time, adjust the first push rods 310 on both sides of the sliding frame 302. The first push rods 310 drive the connecting piece 311, the support rod 312 and the contact block 313 to move. The contact blocks 313 on both sides start to move towards the grate plate until the grate plate is clamped and fixed, and the grate plate is in the center position in the sliding frame 302.

[0025] The working process of controlling the position of the grate using the moving mechanism 3: According to the required grate welding spacing, the relative distance between the two sliding frames 302 is adjusted by simultaneously adjusting the two electric push plates 314. During the movement of the sliding frame 302, the sliding frame 302 drives the grate to move on the connecting plate 8 until the welding end of the grate protrudes from the connecting plate 8 and the distance between the two grate plates reaches the required distance.

[0026] The process of using the moving mechanism 3 to perform welding protection on the grate plate: With the contact blocks 313 on both sides clamping and fixing the grate, the lifting assembly 304 is manually adjusted to block and protect the gaps in the grate.

[0027] The position of the grate is adjusted by setting up a moving mechanism 3. In existing equipment, the welded end of the grate is supported or fixed, which restricts the free expansion and contraction of the grate during heating or cooling. Therefore, a sliding frame 302 that can move the grate when the connecting plate 8 is in a moving position is set up, so that the welded end of the grate protrudes out of the connecting plate 8, thereby avoiding the support or fixation of the welded end of the grate, and solving the above problem.

[0028] By setting up the moving mechanism 3, the grate plate and grate seams are limited. Two sets of contact blocks 313 in the sliding frame 302 are used to clamp and fix the grate plate at the positions where welding is not required, thereby limiting the overall position of the grate plate. The lifting component 304 blocks and protects the grate seams of the grate plate. In this way, the grate plate and grate seams are limited and protected before welding.

[0029] Lifting assembly 304 includes: The top plate 3041 is installed at the end of the spring 303 away from the sliding frame 302; A central rod 3042 is installed inside the top plate 3041, and a lifting frame 3043 is connected to the end of the central rod 3042 away from the top plate 3041. The bottom edge of the lifting frame 3043 is made of magnetic material. The lifting frame 3043 cooperates with the magnetic sheet 307 in the second slide groove 306. A groove is opened at the bottom of the lifting frame 3043, and the end of the lifting frame 3043 away from the sliding frame 302 is set in an arc shape. An outer ring 3044 sleeved on the outside of the central rod 3042 and a wind control component 305 connected to the outer ring 3044; The mounting block 3047 and the locking strip 3048 are slidably connected in the lifting frame 3043. The mounting block 3047 has multiple slots, and the locking strip 3048 is detachably installed in the slots. The locking strip 3048 is adapted to the grate seams of the grate plate. The number of mounting blocks 3047 is installed according to the number of grate seams. The first connecting rod 3045 is disposed outside the mounting block 3047. The first connecting rod 3045 passes through the interior of the lifting frame 3043. The first connecting rod 3045 is connected to the lifting frame 3043 through the first joint. The connecting bracket 3046 is installed outside the first connecting rod 3045.

[0030] The process of using the lifting assembly 304 to protect the grate seams: Before using the equipment, manually pull the connecting frame 3046 according to the position of the grate seam. The connecting frame 3046 drives the first connecting rod 3045 to move. The first connecting rod 3045 begins to move within the first joint, thereby adjusting the position of the mounting block 3047 and the locking strip 3048 below the lifting frame 3043, so that the position of the locking strip 3048 matches the position of the grate seam.

[0031] When the center rod 3042 is manually pressed, the center rod 3042 drives the top plate 3041, outer ring 3044, and lifting frame 3043 to move downward. At this time, the spring 303 is compressed, and the lifting frame 3043 slides downward in the second slide groove 306. The bottom edge of the lifting frame 3043 is attracted and fixed with the magnetic piece 307 in the second slide groove 306. The locking strip 3048 in the mounting block 3047 gradually gets into the grate slot. The bottom of the lifting frame 3043 contacts the upper surface of the grate, covering and shielding the upper surface of the grate.

[0032] After the work is completed, manually lift the center rod 3042, the lifting frame 3043 gradually separates from the magnetic plate 307, the spring 303 gradually returns to its original state, the lifting frame 3043 moves away from the grate, adjust the stroke of the first push rod 310, the contact block 313 moves away from the grate, and the worker manually disassembles the grate.

[0033] By setting up the lifting assembly 304, the connecting frame 3046 drives the first connecting rod 3045, the mounting block 3047, and the positioning strip 3048 to move horizontally, so that the positioning strip 3048 is adapted to the position of the grate slot. By adjusting the position of the lifting frame 3043 and the positioning strip 3048, the lifting frame 3043 covers the grate, and the positioning strip 3048 is placed in the grate slot. This covers and protects the parts of the grate that do not need to be welded, and blocks and protects the grate slot, preventing welding debris from entering the grate slot from above and becoming difficult to handle.

[0034] Risk control component 305 includes: The second push rod 3051 and the telescopic rod 3055 are installed outside the outer ring 3044. The second push rod 3051 is configured as an electric push rod. The connecting box 3052 is set on the telescopic end of the second push rod 3051. The connecting box 3052 is connected to the telescopic rod 3055. The second push rod 3051 is connected to the connecting box 3052 through a second connector. The telescopic rod 3055 is connected to the connecting box 3052 through a third connector. Both the second connector and the third connector are made of rubber. The connecting box 3052 is set in an arc shape. A first through hole 3053 and a second through hole 3054 are formed inside the connecting box 3052. The first through hole 3053 is formed at the bottom of the connecting box 3052, and the second through hole 3054 is formed on the outer convex surface of the connecting box 3052. The inner diameter of the second through hole 3054 gradually increases from the inside to the outside of the connecting box 3052. The vertical pipe 3056 installed above the connecting box 3052 and the connecting ball 3057 connected to the vertical pipe 3056 are hollow inside, and an external pipe is installed on the top of the connecting ball 3057, which is connected to an external exhaust fan. The second connecting rod 3058 and the filter plate 3059 connected to the second connecting rod 3058 are installed inside the connecting ball 3057. The filter plate 3059 is configured as an arc shape with the convex side facing down, and filter holes are opened inside the filter plate 3059. The second connecting rod 3058 is detachably installed on the inner wall of the connecting ball 3057, and the second connecting rod 3058 is made of an adhesive material.

[0035] The process of using the 305 air control component to ventilate the grate: After the welding work is completed, the two second push rods 3051 are started to their maximum stroke. The second push rods 3051 drive the arc-shaped box to move towards the grate plate welding point, and the arc-shaped box gradually detaches from the lifting frame 3043. The external exhaust fan is started, and during the movement of the arc-shaped box, the debris at the grate plate welding point enters the arc-shaped box through the first through hole 3053.

[0036] Subsequently, the two second push rods 3051 are activated alternately to reciprocate between the initial state and the medium stroke. The two second push rods 3051 drive the arc-shaped box to deflect repeatedly, and the arc-shaped box is always on the lifting frame 3043. Debris within the suction range of the second through hole 3054 enters the arc-shaped box through the second through hole 3054.

[0037] The debris entering the arc-shaped box enters the connecting ball 3057 through the vertical pipe 3056. Under the interception of the filter plate 3059, the debris cannot pass through the filter plate 3059. The filter plate 3059 is set with a convex downward arc shape, which makes it difficult for debris to accumulate. The second connecting rod 3058 is made of an adhesive material, which can stick to some of the debris.

[0038] By setting up the wind control component 305, debris at the weld joint of the grate plate and debris above the grate plate are sucked up. By opening the first through hole 3053 and the second through hole 3054 at the bottom and side of the arc-shaped box, debris can be sucked up at close range at the weld joint and at a long distance above the grate plate as the arc-shaped box deflects or moves in the horizontal direction.

[0039] Working principle: Before using the equipment, manually place the two grates to be welded into the two moving mechanisms 3 respectively, and use the moving mechanisms 3 to limit the position of the grates. According to the position of the grate seam, manually pull the connecting frame 3046. The connecting frame 3046 drives the first connecting rod 3045 to move. The first connecting rod 3045 begins to move within the first joint, thereby adjusting the position of the mounting block 3047 and the locking strip 3048 below the lifting frame 3043, so that the position of the locking strip 3048 is adapted to the position of the grate seam. Manually place the grate plate on the connecting plate 8, with one end of the grate plate in contact with the inner wall of the sliding frame 302. At the same time, adjust the first push rods 310 on both sides of the sliding frame 302. The first push rods 310 drive the connecting piece 311, the support rod 312 and the contact block 313 to move. The contact blocks 313 on both sides start to move towards the grate plate until the grate plate is clamped and fixed, and the grate plate is in the center position in the sliding frame 302.

[0040] With the contact blocks 313 on both sides clamping and fixing the grate, the lifting assembly 304 is manually adjusted to block and protect the gaps in the grate.

[0041] Manually press the center rod 3042, which drives the top plate 3041, outer ring 3044, and lifting frame 3043 to move downward. The lifting frame 3043 slides downward in the second slide groove 306. The bottom edge of the lifting frame 3043 is attracted and fixed to the magnetic piece 307 in the second slide groove 306. The locking strip 3048 in the mounting block 3047 gradually gets into the grate slot. The bottom of the lifting frame 3043 contacts the upper surface of the grate, covering and shielding the upper surface of the grate.

[0042] Subsequently, according to the required grate welding spacing, the relative distance between the two sliding frames 302 is adjusted by simultaneously adjusting the two electric push plates 314. During the movement of the sliding frame 302, the sliding frame 302 drives the grate to move on the connecting plate 8 until the welding end of the grate protrudes from the connecting plate 8 and the distance between the two grate plates reaches the required distance.

[0043] Then, the sliding frame 302, the electric push plate 314, and the module 5 are adjusted, and the welding gun 6 is used to complete the assembly and welding of the grate plate.

[0044] After the welding work is completed, the two second push rods 3051 are activated to their maximum stroke. The second push rods 3051 drive the arc-shaped box to move towards the grate welding point, and the arc-shaped box gradually detaches from the lifting frame 3043. The external exhaust fan is then activated, and the debris at the grate welding point enters the arc-shaped box through the first through hole 3053.

[0045] Subsequently, the two second push rods 3051 are activated alternately to reciprocate between the initial state and the medium stroke. The two second push rods 3051 drive the arc-shaped box to deflect repeatedly, and the arc-shaped box is always on the lifting frame 3043. Debris within the suction range of the second through hole 3054 enters the arc-shaped box through the second through hole 3054.

[0046] The debris entering the arc-shaped box enters the connecting ball 3057 through the vertical pipe 3056. Under the interception of the filter plate 3059, the debris cannot pass through the filter plate 3059. The filter plate 3059 is set with a convex downward arc shape, which makes it difficult for debris to accumulate. The second connecting rod 3058 is made of an adhesive material, which can stick to some of the debris.

[0047] After the work is completed, manually lift the center rod 3042, the lifting frame 3043 gradually separates from the magnetic plate 307, the spring 303 gradually returns to its original state, the lifting frame 3043 moves away from the grate, adjust the stroke of the first push rod 310, the contact block 313 moves away from the grate, and the worker manually disassembles the grate.
