Description

Technical Field

[0001] This utility model relates to the field of steel casing flattening technology, and in particular to an integrated steel casing flattening device. Background Technology

[0002] Steel casings are made of steel and have high strength and durability. They can be reused multiple times under normal use and maintenance conditions. In the construction of bridges and highways of all sizes, a large number of steel casings used for piling are left idle as waste materials due to deformation or project completion, occupying a lot of site and space. Therefore, before these steel casings are reused, the outer wall of the steel casing needs to be flattened again. However, the steel plate leveling machines commonly used in the market can only level vertical steel plates, and cylindrical steel casings cannot be inserted into the steel plate leveling machine. Therefore, the existing steel plate leveling equipment cannot level the outer wall of cylindrical steel casings, especially for steel casings with thicker steel plates. Therefore, there is an urgent need for an integrated steel casing flattening equipment to solve the problems existing in the above-mentioned technologies. Utility Model Content

Two rectangular through slots are opened at the top of the first and second support frames respectively. A set of connecting blocks is slidably connected to the inner wall of the rectangular through slot at the top of the first support frame. A rotating frame is fixed to the top outer wall of the connecting blocks. A limit block is slidably connected to the inner wall of the rotating frame.

[0015] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0016] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0017] Example 1: An integrated steel casing flattening device, such as Figure 1-6As shown, the system includes a support frame 1. The top outer wall of the support frame 1 is fixed with a first support frame 7, a second support frame 23, and a gearbox 20. Four support rollers 22 are rotatably connected to the inner walls of opposite sides of the first support frame 7 and the second support frame 23. The top of the first support frame 7 and the second support frame 23 are respectively opened with two rectangular through slots. A set of connecting blocks 8 is slidably connected to the inner wall of the rectangular through slot at the top of the first support frame 7. A rotating frame 14 is fixed to the top outer wall of the connecting block 8. A limit block 16 is slidably connected to the inner wall of the rotating frame 14. A second movable block 21 is slidably connected to the inner wall of the rectangular through slot at the top of the second support frame 23. An upper roller 17 is rotatably connected to the inner wall of opposite sides of the second movable block 21 and the limit block 16. The top outer walls of the support frame 1 and the second support frame 23 are respectively provided with rectangular grooves. The inner wall of the rectangular groove is slidably connected to the first movable block 9. The inner wall of the first movable block 9 is rotatably connected to the pressure roller shaft 13. The top inner wall of the first movable block 9 is connected to the second lead screw 10 by thread. The outer walls of opposite sides of the support frame 1 are respectively fixed with the first motor 12 and the first reducer 11. The output end of the first motor 12 is connected to the input end of the first reducer 11. The output end of the first reducer 11 is connected to the top of the second lead screw 10. The inner walls of the connecting block 8 and the second movable block 21 are respectively fixed with a first lead screw 4. The bottom end of the first lead screw 4 is rotatably connected to the inner wall of the first support frame 7. The outer wall of the first lead screw 4 is connected to a worm gear 6 by a thread. The outer wall of the worm gear 6 is connected to a worm 3. The top outer wall of the support frame 1 is fixed with two sets of second motors 24 and second reducers 25. The output end of the second motor 24 is connected to the input end of the second reducer 25. The two ends of the output shaft of the second reducer 25 are respectively connected to a connecting shaft 26 by a coupling. One end of the worm 3 is connected to the connecting shaft 26 by a coupling. The outer walls of the first support frame 7 and the second support frame 23 are respectively fixed with support seats 2. The worm 3 is rotatably connected to the inner wall of the support seat 2.

[0018] A set of third motors 27 and third reducers 28 are fixed on the top outer wall of the support frame 1. The output end of the third motor 27 is connected to the input end of the third reducer 28, and the output end of the third reducer 28 is connected to the input end of the gearbox 20. Multiple transmission shafts 29 are rotatably connected to the outer wall of the gearbox 20. The transmission shafts 29 are respectively connected to one end of the pressure roller shaft 13, the upper roller shaft 17 and the support roller shaft 22 through a variable stroke universal coupling 30.

[0019] like Figure 1-4 As shown, a fixing frame 18 is fixed to the top outer wall of the second support frame 23, and a set of threaded pressure rods 19 are connected to the inner wall of the fixing frame 18 by threads.

[0020] The outer wall of the rotating frame 14 has an insertion hole 5, and a limiting insert 15 is inserted into the inner wall of the insertion hole 5. The top outer wall of the limiting block 16 has a limiting slot 31, and the limiting insert 15 is slidably connected to the outer wall of the limiting slot 31.

[0021] First, cut open one side of the steel casing that needs to be flattened and maintained. Then, pull out the limiting insert 15 from one side of the rotating frame 14. Then, control the two second motors 24 to rotate synchronously. Drive the worm gears 3 at both ends to rotate through the connecting shaft 26, thereby driving the worm wheel 6 connected to the outer wall of the worm gear 3 to rotate. When the worm wheel 6 rotates, it will drive the first lead screw 4 to move upward through the thread, thereby driving the two upper roller shafts 17 connected between the limiting block 16 and the second movable block 21 to move upward at the same time. When one end of the upper roller shaft 17 moves upward, the bottom end of the threaded pressure rod 19 will abut against one end of the upper roller shaft 17, so that the other end of the upper roller shaft 17 located on the inner wall of the limiting block 16 is slightly raised, thereby creating space between the bottom of the limiting block 16 and the bottom inner wall of the rotating frame 14, allowing the workers to rotate the rotating frame 14 out from the outer wall of the limiting block 16. Then, the steel casing can be inserted between the two upper roller shafts 17 and the bottom support roller shaft 22 through the gap between the limiting block 16 and the first support frame 7. Then, rotate the two rotating frames 14 back to the outer wall of the limiting block 16, and insert the limiting tube 15 between the limiting block 16 and the rotating frame 14 to support and limit the limiting block 16. Subsequently, the staff controlled the first motor 12, the second motor 24 and the third motor 27 to rotate synchronously through the remote controller. When the second motor 24 rotates, it can drive the second movable block 21 and the limit block 16 to move up and down as a whole through the thread, adjusting the distance between the upper roller shaft 17 and the support roller shaft 22, so that the upper roller shaft 17 and the support roller shaft 22 can flatten steel casings and steel plates of different thicknesses. Subsequently, the third motor 27 is controlled by the remote controller to rotate, which drives the upper and lower rows of transmission shafts 29 on one side of the gearbox 20 to rotate relative to each other. Multiple transmission shafts 29 located in the same row rotate in the same direction, thereby driving two upper roller shafts 17 and one pressure roller shaft 13 to rotate in the same direction at a uniform speed through the variable stroke universal coupling 30. Four support roller shafts 22 rotate in the same direction at a uniform speed, pressing the steel casing inserted between the upper roller shaft 17 and the support roller shaft 22 into a flat steel plate. One end of the flat steel plate will move forward under the drive of the upper roller shaft 17 and the support roller shaft 22, thereby directly entering the pressure roller shaft 13 and the support roller shaft 22 located on one side of the support frame 1. The surface of the steel plate is completely flattened by the rolling pressure of the pressure roller shaft 13 and the support roller shaft 22, thereby pressing the cylindrical steel plate into a flat steel plate. In this embodiment, the variable stroke universal coupling 30 changes the overall length of the coupling through a structure such as an elastic telescopic rod, so that the upper roller shaft 17 can always be connected to the gearbox 20 through the variable stroke universal coupling 30 when moving up and down. The variable stroke universal coupling 30 is an existing product that can be purchased on the market and is a mature technology. The specific working principle will not be described in detail here.

[0022] like Figure 6 As shown, a flat steel plate can be inserted between the upper roller shaft 17 and the support roller shaft 22. Then, the third motor 27 is controlled to drive the transmission shaft 29 to rotate, which in turn drives the upper roller shaft 17 to rotate. At this time, the single upper roller shaft 17 and the two support roller shafts 22 at the bottom form the structure of the plate rolling machine in the prior art, which can bend the steel plate into a cylinder. This integrated equipment can both flatten the cylindrical steel plate and press the flat steel plate into a cylinder. It has the functions of both the plate rolling machine and the leveling machine in the existing equipment on the market, forming a multi-purpose machine.

[0023] At the same time, the corresponding second motor 24 can be controlled to drive the upper roller shaft 17 on one side to move downward or upward, so as to avoid the upper roller shaft 17 on one side from blocking the bent steel plate.

[0024] In this embodiment, the first motor 12, the second motor 24, and the third motor 27 are all electrically connected to the external control cabinet via signal control lines. The control cabinet is electrically connected to the remote controller via signal control lines. Therefore, the operator only needs to press the remote controller button to remotely control the rotation of the corresponding motor without having to approach the steel plate or cylinder being processed, thus improving the safety of equipment use. The above-mentioned control cabinet, controller, and signal line connection method are existing mature technologies, and the specific working principle will not be elaborated here.

[0025] In this embodiment, the gearbox 20 is composed of multiple meshing gears. By simultaneously meshing a larger gear with the gears at one end of multiple drive shafts 29, the multiple drive shafts 29 can be driven to rotate in the same direction. The gearbox 20 described above is a mature existing technology, and gearboxes 20 that achieve the above functions can be purchased on the market. Therefore, the specific internal structure and working principle of the gearbox 20 will not be described in detail here.

[0026] Simultaneously, four hydraulic outriggers can be fixed to the outer walls of the support frame 1 to support the entire equipment, thereby facilitating the loading, unloading, and transportation of the entire equipment. In this embodiment, the height of the hydraulic outriggers must reach at least 1.5m. The hydraulic outriggers installed on the outer walls of the support frame 1 are common lifting devices on cranes and other mechanical vehicles, and are mature existing technology. The specific working principle will not be elaborated here.

[0027] Working principle: The steel casing that needs to be flattened and maintained is cut flat on one side. Then, the limiting insert 15 is pulled out from one side of the rotating frame 14. Then, the two second motors 24 are controlled to rotate synchronously. The connecting shaft 26 drives the worm gears 3 at both ends to rotate, thereby driving the worm wheel 6 connected to the outer wall of the worm gear 3 to rotate. When the worm wheel 6 rotates, it will drive the first lead screw 4 to move upward through the thread, thereby driving the two upper roller shafts 17 connected between the limiting block 16 and the second movable block 21 to move upward at the same time. When one end of the upper roller shaft 17 moves upward, the bottom end of the threaded pressure rod 19 will abut against one end of the upper roller shaft 17, so that the other end of the upper roller shaft 17 located on the inner wall of the limiting block 16 is slightly raised, thereby creating space between the bottom of the limiting block 16 and the bottom inner wall of the rotating frame 14, allowing the operator to rotate the rotating frame 14 out from the outer wall of the limiting block 16. Then, the steel casing can be inserted between the two upper roller shafts 17 and the bottom support roller shaft 22 through the gap between the limiting block 16 and the first support frame 7. Then, rotate the two rotating frames 14 back to the outer wall of the limiting block 16, and insert the limiting tube 15 between the limiting block 16 and the rotating frame 14 to support and limit the limiting block 16. Subsequently, the staff controlled the first motor 12, the second motor 24 and the third motor 27 to rotate synchronously through the remote controller. When the second motor 24 rotates, it can drive the second movable block 21 and the limit block 16 to move up and down as a whole through the thread, thereby adjusting the distance between the upper roller shaft 17 and the support roller shaft 22.

[0028] The third motor 27 is controlled by a remote controller to rotate, which drives the upper and lower rows of transmission shafts 29 on one side of the gearbox 20 to rotate relative to each other. Multiple transmission shafts 29 located in the same row rotate in the same direction, thereby driving two upper roller shafts 17 and one pressure roller shaft 13 to rotate in the same direction at a uniform speed through the variable stroke universal coupling 30. The four support roller shafts 22 rotate in the same direction at a uniform speed, pressing the steel protective cylinder inserted between the upper roller shaft 17 and the support roller shaft 22 into a flat steel plate.

[0029] A flat steel plate can be inserted between the upper roller shaft 17 and the support roller shaft 22. Then, the third motor 27 is controlled to drive the transmission shaft 29 to rotate, which in turn drives the upper roller shaft 17 to rotate. At this time, the single upper roller shaft 17 and the two support roller shafts 22 at the bottom form the structure of the plate rolling machine in the prior art, which can bend the steel plate into a cylinder.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
