A steel plate rolling device for ship processing with a protective structure

Abstract

This utility model discloses a shipbuilding plate rolling device with a protective structure, comprising a base plate, two mounting plates connected to the top of the base plate, and a lower roller symmetrically rotating between the mounting plates. A driven gear is fixed to one end of the drive shaft of the lower roller, a reducer is fixed to the top edge of the base plate, and a drive motor is fixed to the top edge of the base plate. This shipbuilding plate rolling device with a protective structure, through the activation of the servo motor, drives the bidirectional screw to rotate, causing the moving blocks to move away from each other outside the limit rod, thereby causing the connecting seats to move away from each other, causing the deflection plate to deflect vertically, thus causing the fixed frame to deflect, causing the protective plate to deflect, and driving the rotating shaft to rotate, thereby tilting the protective plate. This effectively blocks the plate during rolling, preventing the metal plate from falling directly and injuring the operator, improving the device's protective performance, and reducing safety hazards.

Description

Technical Field

[0001] This utility model relates to the field of shipbuilding processing technology, specifically to a shipbuilding processing plate rolling device with a protective structure. Background Technology

[0002] Ships are a general term for all kinds of vessels. A ship is a means of transportation that can navigate or anchor in waterways for transport or operations. Depending on the specific requirements, ships have different technical specifications, equipment, and structural forms. As people's lives continue to improve, the exchange of goods has become more frequent. Ships, as the main means of freight transport, have become extremely important in our lives. Therefore, the shipbuilding industry is also becoming increasingly prosperous. In the shipbuilding industry, we often use rolled steel sheets.

[0003] Chinese patent CN213223855U discloses a plate rolling machine with a safety protection structure, including a base, fixed supports, a drive cabinet, a protective mechanism, and an adjustment mechanism. A pair of fixed supports are fixedly connected to the upper end of the base. The drive cabinet is fixedly connected to the upper end of the base and located outside the fixed supports. The protective mechanism is located on the upper end of the base and on both the front and rear sides of the fixed supports. This application uses a hydraulic cylinder of the protective mechanism to lift the protective plates, thereby protecting the metal plate during rolling. This effectively prevents the metal plate from falling off or breaking during the rolling process, thus preventing injuries caused by the metal plate and improving the safety of the plate rolling machine during production.

[0004] As can be seen from the above patent, during the processing of metal plates, when the metal plate is not completely rolled into a barrel shape, the deviation in the rotation distance can easily cause the metal plate to fall off between the three pressure rollers. Without a protective structure, the metal plate could injure the operator. Therefore, we have proposed a rolling plate device for ship processing with a protective structure. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shipbuilding plate rolling device with a protective structure, comprising a base plate, two mounting plates connected to the top of the base plate, a lower roller symmetrically rotating between the mounting plates, a driven gear fixed to one end of the drive shaft of the lower roller, a reducer fixed to the top edge of the base plate, a drive motor fixed to the top edge of the base plate, a drive gear fixed to the output shaft end of the reducer, a mounting frame connected to the top center of the mounting plates, an electric telescopic rod fixed to the top of the mounting frame, a mounting frame connected to the output shaft end of the electric telescopic rod, and connecting blocks connected inside the mounting frame. The two connecting blocks are positioned relative to each other... An upper roller rotates between the sides. A protective mechanism is connected to the top of the base plate. A connecting mechanism is provided on one side of the mounting plate. The protective mechanism includes a rotating shaft that symmetrically passes through and rotates on one side of the mounting plate. A protective plate is fixed between the opposite sides of the two rotating shafts. A mounting cavity is opened at the top of the base plate. A bidirectional screw rotates through the middle between the opposite sides of the mounting cavity. A moving block is symmetrically screwed to the outer side of the bidirectional screw. Limit rods are symmetrically fixed between the opposite sides of the mounting cavity. A servo motor is fixed on one side of the base plate. A connecting seat is fixed on the top of the moving block. A deflection plate rotates between the two sides inside the connecting seat. A fixing frame is fixed at the bottom edge of the protective plate.

[0007] As a further description of the above technical solution:

[0008] The output shaft end of the drive motor is fixedly connected to the input end of the reducer, and the driving gear meshes with the driven gear.

[0009] As a further description of the above technical solution:

[0010] The movable block is located inside the mounting cavity, and the movable block slides on the outside of the limiting rod.

[0011] As a further description of the above technical solution:

[0012] The two sides of the deflection plate are rotatably connected to the inner sides of the fixed frame, and the output shaft end of the servo motor is fixedly connected to one end of the bidirectional screw.

[0013] As a further description of the above technical solution:

[0014] One of the connecting blocks is fixed inside one of the mounting frames, and the other connecting block slides inside the other mounting frame.

[0015] As a further description of the above technical solution:

[0016] The connecting mechanism includes a T-slot formed on the top of one side of the mounting plate, a connecting plate fixed to the bottom of one side of the mounting plate, a symmetrically sliding insert rod through the top of the connecting plate, a pull plate fixed to the bottom of the insert rod, a return spring symmetrically fixed to the top of the pull plate, a T-block fixed to the bottom of the other mounting bracket, a fixing plate fixed to the bottom of one side of the T-block, and a symmetrically sliding insertion hole through the top of the fixing plate.

[0017] As a further description of the above technical solution:

[0018] The top end of the reset spring is fixed to the bottom of the connecting plate, and the reset spring is sleeved on the outside of the plug rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This shipbuilding plate rolling device with a protective structure, through the activation of a servo motor, drives a bidirectional screw to rotate, causing the moving blocks to move away from each other outside the limit rod, which in turn causes the connecting seats to move away from each other, causing the deflection plate to deflect vertically. This, in turn, causes the fixed frame to deflect, resulting in the deflection of the protective plate. This, in turn, causes the rotating shaft to rotate, thus tilting the protective plate. This effectively blocks the plate during rolling, preventing the metal plate from falling directly and injuring the operator. This enhances the device's protective capabilities and reduces safety hazards.

[0021] This shipbuilding plate rolling device with a protective structure moves the insertion rod by pulling the pull plate, causing the insertion rod to move out of the insertion hole, thereby releasing the fixing plate. Pulling the T-block removes the mounting frame, thus separating a mounting frame from the connecting block, making it easier to remove the rolled plate, facilitating material unloading, and improving the practicality of the device.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] This utility model provides a steel plate rolling device for shipbuilding with a protective structure. During the rolling process, it obstructs the steel plate, preventing it from falling directly and injuring the operator. This improves the device's protective capabilities and reduces safety hazards. (See also...) Figure 1 It includes a base plate 1, and two mounting plates 2 are connected to the top of the base plate 1. A lower roller 201 is symmetrically rotatable between the mounting plates 2. A driven gear 202 is fixed at one end of the drive shaft of the lower roller 201.

[0032] Please refer to it again. Figure 1 A reducer 3 is fixed to the top edge of the base plate 1, a drive motor 301 is fixed to the top edge of the base plate 1, and a drive gear 302 is fixed to the end of the output shaft of the reducer 3.

[0033] Please refer to it again. Figure 1 Mounting plate 2 is connected to the top center of mounting frame 4. An electric telescopic rod 401 is fixed to the top of mounting frame 4. Mounting frame 402 is connected to the end of the output shaft of electric telescopic rod 401. Connecting block 403 is connected inside mounting frame 402. Upper roller 404 rotates between the opposite sides of two connecting blocks 403.

[0034] Please refer to it again. Figure 2 The top of the base plate 1 is connected to a protective mechanism 5, and a connecting mechanism 6 is provided on one side of a mounting plate 2. The protective mechanism 5 includes a rotating shaft 501 that symmetrically passes through and rotates on one side of the mounting plate 2, and a protective plate 502 is fixed between the opposite sides of the two rotating shafts 501.

[0035] Please refer to it again. Figure 3 The top of the base plate 1 is provided with an installation cavity 503. A bidirectional screw 504 is rotatably inserted through the middle between the opposite sides of the installation cavity 503. A moving block 505 is symmetrically screwed to the outside of the bidirectional screw 504. Limiting rods 506 are symmetrically fixed between the opposite sides of the installation cavity 503.

[0036] Please refer to it again. Figure 3 A servo motor 507 is fixed on one side of the base plate 1, a connecting seat 508 is fixed on the top of the moving block 505, a deflection plate 509 rotates between the two sides inside the connecting seat 508, and a fixing bracket 510 is fixed on the bottom edge of the protective plate 502.

[0037] In summary, by starting the servo motor 507, the bidirectional screw 504 is driven to rotate, causing the moving blocks 505 to move away from each other outside the limit rod 506. This, in turn, causes the connecting seats 508 to move away from each other, causing the deflection plate 509 to deflect in the vertical direction. This, in turn, causes the fixed frame 510 to deflect, causing the protective plate 502 to deflect. This, in turn, causes the rotating shaft 501 to rotate, thus tilting the protective plate 502. This effectively blocks the plate during rolling, preventing the metal plate from falling directly and injuring the operator. This improves the protective performance of the device and reduces safety hazards.

[0038] Please refer to it again. Figure 1 The output shaft end of the drive motor 301 is fixedly connected to the input end of the reducer 3, and the driving gear 302 is meshed with the driven gear 202.

[0039] Please refer to it again. Figure 3 The movable block 505 is located inside the mounting cavity 503, and the movable block 505 slides on the outside of the limiting rod 506.

[0040] Please refer to it again. Figure 3 The two sides of the deflection plate 509 are rotatably connected to the inside sides of the fixed frame 510, and the output shaft end of the servo motor 507 is fixedly connected to one end of the bidirectional screw 504.

[0041] Please refer to it again. Figure 1 One connecting block 403 is fixed inside a mounting frame 402, and the other connecting block 403 slides inside another mounting frame 402.

[0042] Please refer to it again. Figure 4 and Figure 5 The connecting mechanism 6 includes a T-slot 601 formed on the top of one side of a mounting plate 2, a connecting plate 602 fixed to the bottom of one side of the mounting plate 2, a symmetrically sliding insert rod 603 through the top of the connecting plate 602, a pull plate 604 fixed to the bottom of the insert rod 603, a return spring 605 symmetrically fixed to the top of the pull plate 604, a T-block 606 fixed to the bottom of another mounting bracket 4, a fixing plate 607 fixed to the bottom of one side of the T-block 606, and a symmetrically sliding insertion hole 608 through the top of the fixing plate 607.

[0043] Please refer to it again. Figure 4 The top end of the return spring 605 is fixed to the bottom of the connecting plate 602, and the return spring 605 is sleeved on the outside of the plug rod 603.

[0044] In summary, by pulling the pull plate 604, the insertion rod 603 is moved out of the insertion hole 608, thereby releasing the fixing plate 607. Pulling the T-block 606 removes the mounting bracket 4, thereby separating the mounting frame 402 from the connecting block 403, which facilitates the removal of the rolled plate, makes material unloading easier, and improves the practicality of the device.

[0045] In practical use, when rolling a metal plate, the person skilled in the art places the metal plate between the upper roller 404 and the lower roller 201, activates the electric telescopic rod 401 to lower the upper roller 404 and press the metal plate, activates the drive motor 301, and uses the transmission of the reducer 3 to drive the drive gear 302 to rotate, causing the driven gear 202 to rotate, which in turn drives the lower roller 201 to rotate. As the metal plate is gradually rolled into a circle, the servo motor 507 is activated. The activation of the servo motor 507 drives the bidirectional screw 504 to rotate, causing the moving blocks 505 to move away from each other outside the limit rod 506, thereby driving the connecting seats 508 to move away from each other. The deflection plate 509 is deflected vertically, which in turn causes the fixing frame 510 to deflect, causing the protective plate 502 to deflect and the rotating shaft 501 to rotate. This causes the protective plate 502 to tilt, thus blocking the plate during rolling and preventing the metal plate from falling off directly. After the plate is rolled, the pull plate 604 is pulled, which moves the insertion rod 603 and moves it out of the insertion hole 608, thereby releasing the fixing plate 607. The T-block 606 is pulled to remove the mounting frame 4, which separates the mounting frame 402 from the connecting block 403, allowing the processed metal cylinder to be removed from the upper roller 404.
