Description

Technical Field

[0001] This invention relates to the field of shell straightening technology, specifically to a device for straightening deformed shells made of fiberglass. Background Technology

[0002] Fiberglass integrated sewage treatment tanks are generally horizontal cylindrical in shape, with end caps typically featuring a mechanically designed concave-convex surface. They contain internal baffles, and the cylinder is manufactured using a mechanical winding process and a high-compression-resistance structure. Currently, the internal baffles of existing fiberglass integrated sewage treatment tanks are installed after the tank shell is completed and placed horizontally on a rotating device. However, when the shell is placed horizontally, it lacks internal support and deforms under its own weight. The upper and lower parts of the shell contract inwards, while the shell expands outwards to the left and right, thus affecting the installation of the internal baffles.

[0003] In response, Chinese patent application number CN202020723672.6 discloses a fiberglass shell deformation correction device, comprising a pair of gantry frames arranged side by side, with a top fixed connection between the two gantry frames, and a horizontally inward pushing correction device on the legs of each gantry frame. This invention solves the problem of shell deformation during the installation of internal partitions in existing fiberglass shells, ensuring that the shell does not deform during partition installation, thus improving the production efficiency and product quality of fiberglass products such as integrated fiberglass sewage treatment tanks.

[0004] The equipment uses a lifting hydraulic cylinder to adjust the height of the straightening hydraulic cylinder, allowing the straightening piston rod to contact the side wall of the fiberglass shell. However, in the actual straightening process, due to the large size of the fiberglass shell, it is impossible to accurately move the straightening hydraulic cylinder to both sides of the horizontal diameter of the fiberglass shell using the lifting hydraulic cylinder. Over-straightening may even occur. Therefore, it is difficult to effectively straighten the shape of the fiberglass shell using the straightening hydraulic cylinder, leaving the surface of the fiberglass shell deformed, which will affect the installation efficiency of the partition inside the shell.

[0005] Therefore, in order to solve the above problems, a deformation correction device for a fiberglass shell is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a deformation correction device for fiberglass shells, which solves the problem mentioned in the background art. In the prior art, the device uses a lifting hydraulic cylinder to adjust the height of the correction hydraulic cylinder so that the correction piston rod can contact the side wall of the fiberglass shell. However, in actual correction, due to the large volume of the fiberglass shell, it is impossible to accurately move the correction hydraulic cylinder to both sides of the horizontal diameter of the fiberglass shell using the lifting hydraulic cylinder, and over-correction may even occur. Therefore, it is difficult to effectively correct the shape of the fiberglass shell using the correction hydraulic cylinder, leaving the surface of the fiberglass shell deformed, which affects the installation efficiency of the partition inside the shell.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a fiberglass shell deformation correction device, comprising: a support, wherein a shell body is placed on the top surface of the support, and an inner support frame is installed on the inner side of the shell body;

[0008] The upper surface of the bracket is provided with a sliding groove;

[0009] The bracket has a positioning structure installed on its inner side. The positioning structure includes a fixed column, which is installed on the inner side of the bracket. A lifting frame is slidably installed inside the upper end of the fixed column. The two ends of the lifting frame are rotatably connected to a first roller. A spring is fixedly connected to the bottom surface of the lifting frame. Two sets of translation rods are inserted into the top surface of the bracket. A second roller is rotatably connected to the top end of the translation rod. A rack plate is fixedly connected to the middle of the translation rod. A first roller is installed at the bottom end of the translation rod. An internally threaded gear cylinder is movably installed inside the slide groove through a bearing. A first threaded rod is threadedly connected inside the internally threaded gear cylinder. A third roller is rotatably connected to the top end of the first threaded rod. Guide frames are fixedly connected to both sides of the upper end of the first threaded rod.

[0010] A correction structure is installed on the right side of the positioning structure. The correction structure includes a guide rod, which is fixedly installed on the right side wall of the bracket. A translation frame is slidably installed on the outer side of the guide rod. A second roller is fixedly connected to the bottom end of the translation frame. A connecting plate is fixedly connected to the upper end of the translation frame. Fixing blocks are fixedly connected to the front and rear surfaces and the top surface of the connecting plate. A sliding cavity is opened on the inner side of the fixing block. A second threaded rod is movably installed on the inner side of the sliding cavity through a bearing. A slider is threadedly connected to the middle of the second threaded rod. A correction cylinder is rotatably connected to the surface of the slider. A first bevel gear is fixedly connected to the end of the second threaded rod. A motor is fixedly connected to the right side wall of the connecting plate. A second bevel gear is fixedly connected to the output end of the motor.

[0011] Preferably, the shell body is located on the upper side of the lifting frame, the surface of the shell body is in contact with the two sets of first rollers at both ends of the lifting frame, the fixed column is fixedly installed on the ground, and one end of the spring is fixedly connected to the inner wall of the fixed column.

[0012] Preferably, the translation rod passes through the bracket via a sliding groove, and the two sets of translation rods are located on the front and rear sides of the shell body respectively, and both sets of the second rollers are in contact with the surface of the shell body.

[0013] Preferably, the rack plate is slidably installed on the inner side of the slide groove, and the two sets of rack plates are staggered and located on both sides of the internal thread gear cylinder, and both sets of rack plates mesh with the internal thread gear cylinder.

[0014] Preferably, the third roller is located between the two sets of second rollers, and the top surface of the third roller is in contact with the shell body. The two sets of second rollers and the third roller form an isosceles right triangle, and the guide frame passes through the support.

[0015] Preferably, the axis of the connecting disc, the midpoint of the distance between the two sets of second rollers, and the axis of the shell body coincide.

[0016] Preferably, the slider is slidably installed inside the sliding cavity, and the three sets of correction cylinders respectively contact the front and rear walls and the top surface of the shell body.

[0017] Preferably, the second bevel gear is movably mounted on the inner side of the connecting disc via a bearing, and the second bevel gear meshes with three sets of first bevel gears.

[0018] Compared with the prior art, the beneficial effects of the present invention are: the correction device of the present invention can help position the shell body on the support by setting a positioning structure, and the position of the axis of the shell body of different sizes is fixed after it is placed on the top surface of the support, so that the shape of the shell body of different sizes can be fixed and corrected by the correction structure, avoiding deformation of the shell body under its own weight, which would lead to damage to the material strength, reducing the obstruction encountered during the installation of the partition, and improving the functionality of the device.

[0019] Equipped with a positioning and correction structure, the shell body is placed downwards on the top surface of the first roller. The lifting frame, in conjunction with the fixing column, limits the front-to-back position of the shell body on the support, ensuring that the shell body can only move up and down in a fixed position, without being able to move forward or backward. Simultaneously, the two sides of the bottom surface of the shell body contact the two sets of second rollers, while the third roller is located directly below the bottom surface of the shell body but does not contact it. Furthermore, the axis of the shell body is vertically aligned with the axis of the third roller. As the shell body is gradually lowered, it presses down on the first roller and applies a force to the two sets of second rollers in the forward and backward directions. Because the cross-section of the shell body is a regular circle under the constraint of the inner support frame, the shell body will press down on the first roller. The rollers cause the lifting frame to descend within the fixed column. The lifting frame compresses the spring, and simultaneously, the main body of the shell pushes two sets of second rollers back and forth. These second rollers slide within a groove via a translation rod, which in turn rolls on the ground via a first roller. The second rollers then roll against the bottom surface of the main body of the shell. As the translation rod moves, it moves the rack plate, which meshes with the outer wall of the internal threaded gear cylinder. The movement of the rack plate causes the internal threaded gear cylinder to rotate within the support. The first threaded rod is inserted into and threadedly connected to the internal threaded gear cylinder. The upper end of the first threaded rod is limited in angle by a guide frame. Therefore, as the internal threaded gear cylinder rotates, it causes the first threaded rod to move downwards within the support. The first threaded rod drives the third roller to descend. Since the third roller and the two sets of second rollers form an isosceles right triangle, the third roller does not contact the shell body during descent. When the distance between the two sets of second rollers is the same as the outer diameter of the shell body, the descent of the shell body on the upper end of the lifting frame can no longer push the two sets of second rollers to move. At this time, the bottom surface of the shell body will contact the top surface of the third roller. The third roller, in conjunction with the first threaded rod, can support the shell body from below, preventing the shell body from driving the lifting frame to continue descending. Therefore, the position of the shell body on the support is fixed at this time, and the axis of the shell body, the midpoint of the line connecting the two sets of second rollers, and the center of the connecting plate are all within the same range. Overlap; push the translation frame, which can move on the ground via the second roller. The guide rod guides and limits the movement of the translation frame, so that the connecting plate fits against the shell body. The three sets of straightening cylinders can be located on the front, rear, and top sides of the shell body respectively. Start the motor, and the motor drives the second bevel gear to rotate. The second bevel gear meshes with the three sets of first bevel gears. The rotation of the second bevel gear drives the three sets of second threaded rods to rotate respectively through the three sets of first bevel gears. The second threaded rods are threadedly connected to the slider. The rotation of the second threaded rods drives the slider to slide inside the slide cavity. The slider drives the straightening cylinder to move on the fixed block, so that the three sets of straightening cylinders fit against the front, rear, and top surfaces of the shell body respectively, which can further fix the shape of the shell body.The inner support frame is pulled out from the shell body. The three sets of straightening cylinders, in conjunction with the third roller, fix the shape of the shell body in four directions, preventing it from collapsing or deforming under gravity. This effectively prevents changes in the shell body's shape during fixing, thus avoiding over-correction and allowing the shell body to maintain its original shape for easy installation of partitions.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-8 One embodiment provided by the present invention:

[0031] The bracket 1, shell body 12, inner support frame 13 and motor 312 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0032] A fiberglass shell deformation correction device includes: a support 1, a shell body 12 placed on the top surface of the support 1, and an inner support frame 13 installed on the inner side of the shell body 12.

[0033] A groove 11 is provided on the upper surface of the bracket 1;

[0034] A positioning structure 2 is installed on the inner side of the bracket 1. The positioning structure 2 includes a fixed column 21. The fixed column 21 is installed on the inner side of the bracket 1. A lifting frame 22 is slidably installed inside the upper end of the fixed column 21. The two ends of the lifting frame 22 are rotatably connected to the first roller 23. The bottom surface of the lifting frame 22 is fixedly connected to the spring 24. Two sets of translation rods 25 are inserted into the top surface of the bracket 1. The top end of the translation rod 25 is rotatably connected to the second roller 26. The middle part of the translation rod 25 is fixedly connected to the rack plate 27. The bottom end of the translation rod 25 is installed with the first roller 28. The inside of the slide groove 11 is movably installed with an internal thread gear cylinder 29 through a bearing. The internal thread of the internal thread gear cylinder 29 is threadedly connected to the first thread rod 210. The top end of the first thread rod 210 is rotatably connected to the third roller 211. The upper ends of the first thread rod 210 are fixedly connected to the guide frame 212 on both sides.

[0035] A straightening structure 3 is installed on the right side of the positioning structure 2. The straightening structure 3 includes a guide rod 31, which is fixedly installed on the right side wall of the bracket 1. A translation frame 32 is slidably installed on the outer side of the guide rod 31. A second roller 33 is fixedly connected to the bottom end of the translation frame 32. A connecting plate 34 is fixedly connected to the upper end of the translation frame 32. Fixing blocks 35 are fixedly connected to the front and rear surfaces and the top surface of the connecting plate 34. A sliding cavity 36 is opened on the inner side of the fixing block 35. A second threaded rod 37 is movably installed on the inner side of the sliding cavity 36 through a bearing. A slider 38 is threadedly connected to the middle of the second threaded rod 37. A straightening cylinder 39 is rotatably connected to the surface of the slider 38. The end of the threaded rod 37 is fixedly connected to the first bevel gear 310, and the right side wall of the connecting plate 34 is fixedly connected to the motor 312. The output end of the motor 312 is fixedly connected to the second bevel gear 311. By setting the positioning structure 2, the shell body 12 can be assistedly positioned on the bracket 1. After the shell bodies 12 of different sizes are placed on the top surface of the bracket 1, the position of their axis is fixed so that the shape of the shell bodies 12 of different sizes can be fixed and corrected by the correction structure 3, so as to avoid the shell body 12 from deforming under its own weight, which would lead to damage to the material strength, reduce the obstruction during the installation of the partition, and improve the functionality of the device.

[0036] Furthermore, the shell body 12 is located on the upper side of the lifting frame 22. The surface of the shell body 12 contacts the two sets of first rollers 23 at both ends of the lifting frame 22. The fixing column 21 is fixedly installed on the ground. One end of the spring 24 is fixedly connected to the inner wall of the fixing column 21. The lifting frame 22, in conjunction with the fixing column 21, can limit the placement of the shell body 12 on the support 1, so that the shell body 12 can only move in the vertical direction and will not move back and forth. This ensures that the pushing effect of the shell body 12 on the two sets of second rollers 26 is consistent, so that when the shell body 12 contacts the third roller 211, the third roller 211 and the two sets of second rollers 26 can still form an isosceles right triangle, so as to keep the axis of the shell body 12 coincident with the axis of the connecting plate 34, so that the correction structure 3 can fix shell bodies 12 of different sizes. The spring 24 provides power for the resetting of the lifting frame 22.

[0037] Furthermore, the translation rod 25 passes through the bracket 1 via the slide groove 11. The two sets of translation rods 25 are located on the front and rear sides of the shell body 12 respectively. The two sets of second rollers 26 are in contact with the surface of the shell body 12. The shell body 12 can push the two sets of second rollers 26, and the pushing force is consistent.

[0038] Furthermore, the rack plate 27 is slidably installed on the inner side of the slide groove 11. The two sets of rack plates 27 are staggered and located on both sides of the internal thread gear cylinder 29. Both sets of rack plates 27 mesh with the internal thread gear cylinder 29. When the translation rod 25 moves, the rack plate 27 can drive the internal thread gear cylinder 29 to rotate, providing power for the lifting and lowering movement of the first thread rod 210.

[0039] Furthermore, the third roller 211 is located between the two sets of second rollers 26, and the top surface of the third roller 211 contacts the shell body 12. The two sets of second rollers 26 and the third roller 211 form an isosceles right triangle. The guide frame 212 passes through the bracket 1 and provides a limit for the vertical movement of the first threaded rod 210. When the two sets of second rollers 26 move back and forth, the distance they move can be consistent with the distance the third roller 211 moves, so as to ensure that when the two sets of second rollers 26 and the third roller 211 contact the shell body 12 at the same time, the midpoint between the two sets of second rollers 26 will coincide with the axis of the shell body 12.

[0040] Furthermore, the axis of the connecting disc 34, the midpoint of the distance between the two sets of second rollers 26, and the axis of the shell body 12 coincide. When the shell body 12 is fixed on the bracket 1, the three sets of straightening cylinders 39 can be located on the front, rear, and upper sides of the shell body 12 respectively, so as to fix the shape of the shell body 12.

[0041] Furthermore, the slider 38 is slidably installed inside the slide cavity 36, and the three sets of straightening cylinders 39 respectively contact the front and rear walls and the top surface of the shell body 12. The slider 38 moves stably within the fixing block 35, and the three sets of straightening cylinders 39 cooperate with each other to fix the shape of the shell body 12.

[0042] Furthermore, the second bevel gear 311 is movably mounted on the inner side of the connecting plate 34 via a bearing. The second bevel gear 311 meshes with three sets of first bevel gears 310. The rotation of the second bevel gear 311 can drive the three sets of first bevel gears 310 to rotate, so that the three sets of straightening cylinders 39 can be displaced simultaneously, ensuring the fixing effect on the shape of the shell body 12 and avoiding over-correction of the shell body 12.

[0043] Working principle: During production, an inner support frame 13 is provided on the inner side of the shell body 12 to support the shell body 12 on the inner side, so that the shell body 12 maintains a regular cylindrical shape. At this time, the third roller 211 and the two sets of second rollers 26 at the front and rear form an isosceles right triangle.

[0044] When a partition needs to be installed, the shell body 12 is placed downwards on the top surface of the first roller 23. The lifting frame 22, in conjunction with the fixing column 21, can limit the front-to-back position of the shell body 12 on the support 1, so that the shell body 12 can only move up and down in a fixed position and cannot move forward and backward. At the same time, the two sides of the bottom surface of the shell body 12 will contact the two sets of second rollers 26, while the third roller 211 is located directly below the bottom surface of the shell body 12, but does not contact the shell body 12, and the axis of the shell body 12 will be vertically aligned with the axis of the third roller 211. The shell body 12 is gradually lowered, and the shell body 12 presses down on the first roller 23. Roller 23, and respectively apply force to two sets of second rollers 26 in the forward and backward directions. Since the cross-section of the shell body 12 is a regular circle under the restriction of the inner support frame 13, the shell body 12 will press down the first roller 23, so that the lifting frame 22 will descend in the fixed column 21. The lifting frame 22 compresses the spring 24. At the same time, the shell body 12 will push the two sets of second rollers 26 back and forth. The second rollers 26 will slide in the slide groove 11 through the translation rod 25, and the translation rod 25 will roll on the ground through the first roller 28. The second rollers 26 will roll against the bottom surface of the shell body 12.

[0045] When the translation rod 25 moves, it will drive the rack plate 27 to move. The rack plate 27 meshes with the outer wall of the internal thread gear cylinder 29. The movement of the rack plate 27 will drive the internal thread gear cylinder 29 to rotate inside the bracket 1. The first threaded rod 210 is inserted into the internal thread gear cylinder 29 and is threadedly connected to the internal thread gear cylinder 29. At the same time, the upper end of the first threaded rod 210 is limited by the guide frame 212. Therefore, when the internal thread gear cylinder 29 rotates, it will drive the first threaded rod 210 to move downward inside the bracket 1. The first threaded rod 210 will drive the third roller 211 to descend. Since the third roller 211 and the two sets of second rollers 26 form an isosceles right triangle, the third roller 211 does not contact the shell body 12 when it descends.

[0046] When the distance between the two sets of second rollers 26 is the same as the outer diameter of the shell body 12, the descent of the shell body 12 at the upper end of the lifting frame 22 can no longer push the two sets of second rollers 26 to move. At this time, the bottom surface of the shell body 12 will contact the top surface of the third roller 211. The third roller 211, in conjunction with the first threaded rod 210, can support the shell body 12 from below, so that the shell body 12 cannot drive the lifting frame 22 to continue to descend. Therefore, at this time, the position height of the shell body 12 on the support 1 is fixed, and at this time, the axis of the shell body 12, the midpoint of the line connecting the two sets of second rollers 26, and the center of the connecting plate 34 coincide.

[0047] The translation frame 32 is pushed and can move on the ground via the second roller 33. The guide rod 31 guides and limits the movement of the translation frame 32, so that the connecting plate 34 fits against the shell body 12. The three sets of straightening cylinders 39 can be located on the front, rear and top sides of the shell body 12 respectively. The motor 312 is started, and the motor 312 drives the second bevel gear 311 to rotate. The second bevel gear 311 meshes with the three sets of first bevel gears 310. The rotation of the second bevel gear 311 drives the three sets of second threaded rods 37 to rotate respectively through the three sets of first bevel gears 310. The second threaded rods 37 are threadedly connected to the slider 38. The rotation of the second threaded rods 37 drives the slider 38 to slide inside the sliding cavity 36. The slider 38 drives the straightening cylinders 39 to move on the fixed block 35, so that the three sets of straightening cylinders 39 fit against the front, rear and top sides of the shell body 12 respectively, which can further fix the shape of the shell body 12.

[0048] The inner support frame 13 is pulled out from the shell body 12. The three sets of straightening cylinders 39, together with the third roller 211, can fix the shape of the shell body 12 in four directions, preventing the shell body 12 from collapsing and deforming under the action of gravity. It also effectively prevents changes in the shape of the shell body 12 during fixing, thereby avoiding over-correction and allowing the shell body 12 to maintain its original shape for easy installation of partitions.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any modifications, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
