Description

TECHNICAL FIELD

[0001] The utility model relates to the field of grate plate assembly, specifically, relate to a kind of assembly tool of grate plate. BACKGROUND

[0002] Grate plate is important component in cement rotary kiln, mainly used for supporting and conveying clinker, while promoting heat exchange. Grate plate is strip or plate, with gap on surface, facilitating hot gas passing through, and this structure of grate plate, which can reliably support while having gap, makes clinker evenly heated during conveying, avoiding local overheating or overcooling.

[0003] The space between the two adjacent channel steels of the grate plate is provided, which is the gap of the grate plate. After the angle steel cover is arranged above the gap, the grate plate can be used to support and transport the clinker, and heat exchange can also be realized through the gap.

[0004] In the production process of the grate plate, the assembly gap between the channel steels is particularly important. However, in the current production process, the space between the two adjacent channel steels needs to be controlled by manual experience assisted measurement with a caliper. The operator needs to measure while welding, which is very low in work efficiency, and the non-standard placement of the caliper can also easily lead to unqualified gap after welding. UTILITY MODEL CONTENT

[0005] The utility model aims to provide a kind of assembly tool of grate plate, which guarantees the gap of the grate plate during production by setting a fixed plate.

[0006] To achieve the above-mentioned purpose, the utility model provides an assembly tool of grate plate, which comprises a tool body, a workbench, a first limiter, a second limiter, a positioning plate and a clamp, the workbench is fixedly connected to the upper surface of the tool body, the first limiter and the second limiter are located on the tool body and are arranged perpendicular to each other, the clamp is arranged parallel to the first limiter and is located on both sides of the workbench respectively.

[0007] The clamp and the workbench are slidably connected, and the clamp realizes clamping of the grate plate by approaching the workbench.

[0008] The positioning plate is perpendicular to the workbench, and the thickness of the positioning plate is consistent with the gap of the grate plate.

[0009] Preferably, a limiting hole is provided on the workbench, which cooperates with the positioning plate, and a plurality of limiting holes are provided, which are one-to-one corresponding to the gaps of the grate plate.

[0010] Preferably, one end of the positioning plate matched with the limiting hole is provided with a taper, and the height of the taper is not greater than the distance between the lower surface of the workbench and the tool body.

[0011] Preferably, the assembling tool of the grate plate further comprises a positioner, the positioner comprising a positioning hole and a positioning rod matched with the positioning hole, the positioning hole being fixedly connected with the tool body, and the positioning rod matched with the positioning hole realizing the position limitation of the positioning plate.

[0012] Preferably, the length of the positioning plate along the width direction of the grate plate is not less than half of the width of the grate plate.

[0013] Preferably, the positioning plate is provided with a support surface perpendicular to the positioning plate, and the support surface is attached to the upper surface of the workbench.

[0014] Preferably, the clamping device is connected with the side surface of the workbench through an adjusting mechanism, and the adjusting mechanism adjusts the distance between the clamping device and the first positioner.

[0015] Preferably, the assembling tool of the grate plate further comprises a guide mechanism capable of guiding the clamping device.

[0016] Preferably, the adjusting mechanism comprises an adjusting bolt and an adjusting nut matched with the adjusting bolt, the adjusting nut being fixedly connected with the tool body, and the end of the adjusting bolt abutting against the clamping device.

[0017] Preferably, the value of the flatness of the workbench is consistent with the design value of the flatness of the grate plate.

[0018] According to the above technical solution, the groove steel for producing the grate plate is laid flat on the workbench, and then the positioning plate is placed between the two adjacent groove steels, the positioning plate is used to limit the distance between the two adjacent groove steels, the positioning plate can be taken out after welding, and the gap between the two adjacent groove steels of the manufactured grate plate is equal to the thickness of the positioning plate. Therefore, by setting the thickness of the positioning plate to be consistent with the gap of the grate plate, the gap value of the grate plate after welding can be reliably ensured. Preferably, the positioning plate can be kept for a period of time after the welding of the grate plate is completed, so as to avoid the influence of welding deformation and temperature change of the grate plate on the gap of the grate plate.

[0019] To prevent the channel steel from shifting during welding, the grate assembly fixture also includes a positioning mechanism. By placing the first channel steel against the second and first limiters, its position is restricted. Then, the positioning plate is placed, followed by the second channel steel, and so on, until all channel steels are placed on the worktable. After placement, the clamps are pushed towards the first limiter. Simultaneously, the channel steel furthest from the first limiter is also pushed, using the pushing force to bring the channel steels and positioning plates on the worktable closer together, ensuring that the distance between adjacent channel steels equals the thickness of the positioning plate. Finally, locking the clamps secures the channel steels and positioning plates on the worktable. Welding the channel steels at this point reliably ensures the weld seam of the grate.

[0035] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0036] In this utility model, unless otherwise stated, directional words such as "vertical," "both sides," "parallel," "close to," "conical," "upper surface," and "side" contained in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the terminology.

[0037] See Figure 1 A grate assembly fixture includes a fixture body 1, a workbench 2, a first limiter 3, a second limiter 4, a positioning plate 5, and a clamping device 6. The workbench 2 is fixedly connected to the upper surface of the fixture body 1. The first limiter 3 and the second limiter 4 are located on the fixture body 1 and are perpendicular to each other. The clamping device 6 is parallel to the first limiter 3 and is located on both sides of the workbench 2.

[0038] The clamp 6 is slidably connected to the worktable 2, and the clamp 6 clamps the grate plate by being close to the worktable 2;

[0039] Positioning plate 5 is perpendicular to the workbench, and the thickness of positioning plate 5 is consistent with the gap of the grate plate.

[0040] By implementing the above technical solution, the channel steel 10 for producing the grate is first laid flat on the workbench 2. Then, a positioning plate 5 is placed between two adjacent channel steels 10 to limit the distance between them. After welding, the positioning plate 5 can be removed. The gap between two adjacent channel steels 10 in the finished grate is then equal to the thickness of the positioning plate 5. Therefore, by setting the thickness of the positioning plate 5 to match the gap of the grate, the gap value after welding can be reliably guaranteed. Preferably, the positioning plate 5 can be kept for a period of time after welding to avoid welding deformation and temperature changes affecting the gap of the grate.

[0041] To prevent the channel steel 10 from shifting during welding, the grate assembly fixture also includes a positioning mechanism. By placing the first channel steel 10 close to the second limiter 4 and the first limiter 3, the position of the first channel steel 10 is restricted. Then, the positioning plate 5 is placed, followed by the second channel steel 10, and so on, until all channel steels 10 are placed on the worktable 2. After placement, the clamping device 6 is pushed towards the first limiter 3. Simultaneously, the channel steel 10 furthest from the first limiter 3 is also pushed, thus using the pushing force to bring the channel steel 10 on the worktable 2 and the positioning plate 5 close together, ensuring that the distance between two adjacent channel steels 10 is equal to the thickness of the positioning plate 5. Finally, locking the clamping device 6 secures the channel steel 10 and the positioning plate 5 on the worktable 2. Welding the channel steel 10 at this point reliably ensures the weld seam of the grate.

[0042] In this embodiment, preferably, the worktable is provided with limiting holes 21, which cooperate with the positioning plate 5. Multiple limiting holes 21 are provided, and each limiting hole 21 corresponds one-to-one with the gap in the grate plate.

[0043] The limiting hole 21, in conjunction with the positioning plate 5, restricts the relative position of the positioning plate 5 and the worktable 2. Multiple limiting holes 21 on the worktable 2 limit the position of the channel steel 10 on the worktable. The first positioning plate 5 is installed in the limiting hole 21 closest to the second limiting device 4, and the first channel steel 10 is placed between the first positioning plate 5 and the second limiting device 4, thus determining the position of the first channel steel 10 on the worktable 2. Similarly, the position of the second channel steel 10 can be limited by the first positioning plate 5 and the second positioning plate 5, and so on down to the penultimate channel steel 10. The position of the penultimate channel steel 10 is limited by the last positioning plate 5 and the penultimate positioning plate 5. The last channel steel 10 can be limited by adding a limiting hole 21 and a positioning plate 5, or it can be manually pushed closer to the last positioning plate 5 during welding. Then, pushing the clamping device 6 closer to the first limiting device 3 and locking the limiting device 3 clamps the channel steel 10 on the worktable 2. This ensures that the relative position of the channel steel 10 does not change during the welding process. This not only effectively ensures that the gap size of the grate meets the design requirements, but also effectively avoids welding deformation, ultimately ensuring the production qualification rate of the grate.

[0044] In this preferred embodiment, the end of the positioning plate 5 that mates with the limiting hole 21 is tapered, and the height of the tapered section is not greater than the distance between the lower surface of the workbench 2 and the tooling body 1.

[0045] The end of the positioning plate 5 that mates with the limiting hole 21 is provided with a taper, which makes it easy to insert the positioning plate 5 into the limiting hole 21. Preferably, the height of the taper is not higher than the distance between the worktable 2 and the tooling body 1, and the width of the limiting hole 21 is the same as the width of the positioning plate 5, so that the positioning plate 5 will not wobble after mating with the limiting hole 21, and the limiting hole 21 can effectively limit the positioning plate 5.

[0046] In this embodiment, preferably, the assembly fixture for the grate plate further includes a positioner, which includes a positioning hole 51 and a positioning rod that cooperates with the positioning hole 51. The positioning rod cooperates with the positioning hole 51 to limit the position of the positioning plate 5.

[0047] The positioner can limit the position of the positioning plate 5, thereby limiting the position of the channel steel 10 on the workbench 2.

[0048] In one embodiment, a positioning hole 51 is provided on the first limiter 3, and a hole is provided on the positioning plate 5 to cooperate with the positioning rod. By passing the positioning rod sequentially through the positioning hole 51 and the positioning plate 5, the position of the positioning plate 5 can be restricted. Preferably, to make the position restriction of the positioning plate 5 by the positioning rod more reliable, a second positioning hole corresponding to the positioning hole 51 can also be provided on the clamping device 6. The positioning rod can reliably restrict the position of the positioning plate 5 by passing sequentially through the positioning hole 51, the positioning plate 5, and the second positioning hole. Preferably, two positioning rods are provided corresponding to each positioning plate 5. The two ends of one positioning rod are inserted into the positioning hole 51 and the positioning plate 5 respectively, and the two ends of the other positioning rod are inserted into the positioning plate 5 and the second positioning hole. This method can also achieve the position restriction of the positioning plate 5.

[0049] More preferably, the positioning hole 51 is set to be elongated. After the positioning rod passes through the positioning hole 51, it is tightened by a nut. When the nut is tightened, the positional relationship between the positioning rod and the positioning hole 51 no longer changes, thereby limiting the position of the positioning plate 5. By setting the elongated positioning hole 51, the versatility of the grate assembly tooling for grate plates of different sizes can be improved, thereby improving the utilization efficiency of the grate assembly tooling.

[0050] In one embodiment, each positioning plate 5 corresponds to a positioning rod. By inserting one end of the positioning rod into the positioning plate 5 and locking the other end with a nut, the relative positional relationship between the positioning rod and the first limiter 3 remains unchanged, thereby achieving positional restriction of the positioning plate 5. In another embodiment, the positioning plate 5 is provided with a through hole for the positioning rod to pass through. The first limiter 3 and the second limiter 4 are respectively provided with corresponding positioning holes 51 and 52. Both ends of the positioning rod are provided with tightening threads. Two locking nuts are tightened on both ends of the positioning rod from the outside of the first limiter 3 and the second limiter 4, respectively. After tightening, reliable positioning of the positioning plate 5 can be achieved.

[0051] In this embodiment, preferably, the length of the positioning plate 5 along the width direction of the grate is not less than half the width of the grate.

[0052] By limiting the length of the positioning plate 5 along the width direction of the grate to no less than half the width of the grate, in actual production, the positioning plate 5 can not only limit the gap width between two adjacent channel steels 10, but also control the parallelism between the two grates. This makes it less likely for the channel steels 10 on both sides of the grate to shift during production, thereby improving production efficiency.

[0053] In this embodiment, preferably, the positioning plate 5 is provided with a support surface 53 perpendicular to the positioning plate 5, and the support surface 53 is in contact with the upper surface of the workbench 2.

[0054] The support surface 53 ensures that the positioning plate 5 is in a position perpendicular to the upper surface of the workbench 2. This ensures that when two adjacent channel steels 10 are close to the positioning plate 5, the distance between the two channel steels 10 is equal to the thickness of the positioning plate 5, which can more effectively ensure the quality of the grate gap.

[0055] In this embodiment, preferably, the clamp 6 is connected to the side of the worktable 2 through an adjustment mechanism, which adjusts the distance between the clamp 6 and the first limiter 3.

[0056] The adjustment mechanism can be configured as any mechanism capable of driving in a straight line.

[0057] In one embodiment, the adjusting mechanism is configured as a lead screw and nut mechanism. The nut is fixedly connected to the clamping device 6 and limits both ends of the clamping device 6. The clamping device 6 can be restricted by the tooling body 1 and the limiting at both ends, preventing the clamping device 6 from rotating during the rotation of the lead screw. The lead screw can be set at the lower part of the working body 1, and the nut is screwed to the lead screw. By rotating the lead screw, the nut is pushed to drive the clamping device 6 to make linear motion.

[0058] In another embodiment, a cylinder can be used to push the clamp 6 closer to or further away from the first limiter 3. The end of the cylinder push rod is fixedly connected to the clamp 6, and the extension or retraction of the cylinder push rod can be achieved by operating the cylinder to allow air to enter or exit, thereby driving the clamp 6 closer to or further away from the first limiter 3.

[0059] Preferably, at least two adjustment mechanisms are provided, and multiple adjustment mechanisms are evenly distributed along the length direction of the clamp 6, so that the clamp 6 can be uniformly stressed along its length direction.

[0060] In this embodiment, preferably, the grate assembly fixture also includes a guide mechanism capable of guiding the clamping device 6.

[0061] The guide mechanism ensures that the clamp 6 moves in a state that is always parallel to the first limiter 3.

[0062] In one embodiment, the guiding mechanism is configured as a guide rod perpendicular to the first limiter 3, and the clamping device 6 is provided with a guide hole that mates with the guide rod. One end of the guide rod is fixedly connected to the worktable 2 or the first limiter 3, or other mechanisms that are fixedly connected to the tooling body 1, and the other end passes through the guide hole on the clamping device 6, which is placed on the upper surface of the tooling body 1. The interaction between the guide hole and the tooling body ensures that the clamping device 6 can only move along the upper surface of the tooling platform. Preferably, two guide rods can be provided, parallel to each other. These two parallel guide rods provide reliable guidance for the clamping device 6, ensuring that the clamping device 6 remains parallel to the first limiter 3 during movement. This achieves reliable clamping of all the channel steels 10 on the worktable 2.

[0063] In this embodiment, preferably, the adjustment mechanism includes an adjustment bolt 71 and an adjustment nut 72 that cooperates with the adjustment bolt 71. The adjustment nut 72 is fixedly connected to the tooling body 1, and the end of the adjustment bolt 71 abuts against the clamp 6.

[0064] The length of the adjusting bolt 71 extending beyond the adjusting nut 72 is adjusted by rotating the adjusting bolt 71, thereby changing the position of the end of the adjusting bolt 71 relative to the adjusting nut. The end of the adjusting bolt 71 abuts against the clamp 6. When the clamp 6 needs to move closer to the first limiter 3, extending the adjusting bolt 71 pushes the clamp 6 closer to the first limiter 3. When it is necessary to remove the clamp 6, rotating the adjusting bolt 71 retracts the adjusting bolt 71, and the clamp 6 can be manually pushed out. Preferably, the end of the adjusting bolt 71 can be fixedly connected to the clamp 6 by welding or other methods, so that the clamp 6 can be retracted together with the adjusting bolt 71 without manual operation.

[0065] In this embodiment, preferably, the flatness value of the workbench 2 is consistent with the design value of the flatness of the grate.

[0066] The flatness of the grate plate during assembly can be controlled by adjusting the flatness of the workbench 2. Under the clamping action of the clamping device 6, the flatness of the grate plate can be well guaranteed during and after welding.

[0067] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0068] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0069] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
