Description

Technical Field

[0001] This invention relates to the field of pickling continuous rolling mill technology, and in particular to a tooling for changing the rollers of a looper swing gate. Background Technology

[0002] The function of the looper in the pickling mill of the cold rolling plant is to provide continuous production conditions when the inlet section is preparing steel coils and welding operations. Each looper mainly consists of a looper car and several swing gates. The looper swing gates are all paired. Depending on the number of strip layers in the looper, each set of looper swing gates contains several pairs of idler rollers. During the looper's operation, the strip is supported by the swing gate idler rollers and travels on them. Because the swing gate idler rollers are rubber rollers, the roller surface is easily worn during service due to the friction between the strip and the idler rollers, thus requiring frequent replacement of the looper swing gate idler rollers.

[0003] Because the looper assembly is installed in a concrete pit, cranes and other lifting equipment cannot directly lift the idler rollers. Therefore, each time the idler rollers are replaced, they need to be removed and installed manually inside the looper, which is very labor-intensive, poses a high risk to construction safety, and has low replacement efficiency. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a tooling for changing the idler roller of a sliding swing door, which solves the problems of high labor intensity, high safety risk and low replacement efficiency when changing the idler roller in the prior art.

The transfer trolley includes a frame and a third drive device. The first end of the frame is rotatably provided with a drive shaft, and the second end of the frame is rotatably provided with a driven shaft. Both ends of the drive shaft are provided with drive rollers, and both ends of the driven shaft are provided with driven rollers. The drive rollers at both ends of the drive shaft are respectively disposed in the front guide rail and the rear guide rail, and the driven rollers at both ends of the driven shaft are respectively disposed in the front guide rail and the rear guide rail. The third drive device is used to drive the drive shaft to rotate, and the third drive device is electrically connected to the control system.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0047] Please see Figures 1 to 6 It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0048] In the following description, "front and back" indicates the direction of movement of the base, and "left and right" indicates the direction of movement perpendicular to the base 10.

[0049] This invention provides a tooling for changing the roller of a movable swing door (hereinafter referred to as "the changing tooling"), such as... Figures 1 to 6As shown, the replacement fixture 100 includes a base 10, on which a traveling mechanism is provided. The traveling mechanism can move along the original looper track 50. A rotating platform is rotatably provided on the base 10. Specifically, a roller storage rack 13 is also fixedly provided on the base 10. It also includes a hoisting mechanism, which includes a support rod 21, a boom 22, and a winch 23. The support rod 21 is fixedly mounted on the rotating platform. The first end of the boom 22 is connected to the support rod 21. The winch 23 is rotatably mounted on the boom 22. A lifting rope 231 is wound on the winch 23. The first end of the lifting rope 231 extends downward past the second end of the boom 22. It also includes a first drive device, a second drive device, and a control system. The first drive device is used to drive the winch 23 to rotate. The second drive device is used to drive the rotating platform to rotate. The traveling mechanism, the first drive device, and the second drive device are all connected to the control system.

[0050] The beneficial effect of the loose-fitting swing door roller replacement fixture of the present invention is that, when replacing roller 510, such as Figure 1 and Figure 2 As shown, the replacement fixture 100 is placed on the existing looper track 50. The old idler rollers, disassembled, are lifted from the swing door 51 and placed on the idler roller storage rack 13 using the lifting mechanism on the replacement fixture 100. Then, the new idler rollers, pre-placed on the rack 13, are lifted to the required installation position using the lifting mechanism, thus completing the idler roller replacement. Furthermore, the second drive device 122 drives the rotating platform to rotate, which in turn drives the lifting mechanism, enabling the replacement of idler rollers located on both sides of the looper track 50. Moreover, by moving the replacement fixture 100 along the existing looper track 50, idler rollers on multiple swing doors spaced apart along the length of the looper track 50 can be lifted and replaced. Therefore, compared with the prior art, the looper swing door idler roller replacement fixture of this invention avoids manual up-and-down and back-and-forth handling of idler rollers, greatly reducing labor intensity, saving labor costs, significantly reducing safety risks, and improving work efficiency.

[0051] Furthermore, such as Figure 3 As shown, in this embodiment, the first end of the lifting rope 231 is provided with a hook 2311, which facilitates the lifting of the idler roller 510. Specifically, in this embodiment, the lifting rope 231 is a steel wire rope.

[0052] Specifically, such as Figure 3As shown, in this embodiment, the idler roller storage rack 13 includes a first idler roller storage rack 131 fixedly disposed on the front side of the base and a second idler roller storage rack 132 fixedly disposed on the rear side of the base 10. When an idler roller 510 is placed on the idler roller storage rack 13, the first idler roller storage rack 131 is used to support one end of the idler roller 510, and the second idler roller storage rack 132 is used to support the other end of the idler roller 510. In order to improve the stability of the idler roller when placed on the idler roller storage rack, grooves are provided on both the first idler roller storage rack 131 and the second idler roller storage rack 132. When an idler roller is placed on the idler roller storage rack 13, both ends of the idler roller are placed in the grooves on the first idler roller storage rack 131 and the second idler roller storage rack 132, respectively.

[0053] As a preferred option, such as Figure 3 As shown, roller storage racks 13 are provided on both the left and right sides of the base 10, so that during operation, new rollers to be installed can be placed on one side of the roller storage rack 13, and old rollers that have been removed can be placed on the other side of the roller storage rack 13.

[0054] Furthermore, such as Figure 3 and Figure 4 As shown, in this embodiment, the walking mechanism includes a left walking wheel set 111, a left drive device, a right walking wheel set 112, and a right drive device. Specifically, the left walking wheel set 111 is rotatably disposed at the left end of the base 10, and the left drive device is used to drive the left walking wheel set 111 to rotate. The right walking wheel set 112 is rotatably disposed at the right end of the base 10, and the right drive device is used to drive the right walking wheel set 112 to rotate. Specifically, the left drive device and the right drive device in this walking mechanism are electrically connected to the control system. During operation, the left drive device and the right drive device synchronously drive the left walking wheel set 111 and the right walking wheel set 112 to move along the looper track 50. Since multiple sets of swing doors are arranged at intervals along the extension direction of the looper track 50, the base 10, i.e., the tooling replacement assembly, is driven to move along the looper track by the left drive device and the right drive device, thereby enabling the lifting, disassembly, and installation of new rollers on the multiple swing doors arranged along the length direction of the looper track.

[0055] Furthermore, such as Figure 3 and Figure 4 As shown, in this embodiment, the left travel wheel assembly 111 includes a left drive wheel 1111 and a left driven wheel 1112 rotatably disposed at the left end of the base 10. The left drive device includes a left drive motor 113, which is connected to the left drive wheel 1111 via a first chain drive assembly 115. Similarly, the right travel wheel assembly 112 includes a right drive wheel 1121 and a right driven wheel 1122 rotatably disposed at the right end of the base 10. The right drive device includes a right drive motor 114, which is connected to the right drive wheel 1121 via a second chain assembly 116.

[0056] Specifically, such as Figure 3 and Figure 4 As shown, the first chain drive assembly 115 includes a left drive sprocket 1151 mounted on the drive shaft of the left drive motor 113, and a left driven sprocket 1152 mounted on the left drive sprocket 1111. The left drive sprocket 1151 is connected to the left driven sprocket 1152 via a left drive chain (not shown in the figure). The second chain drive assembly 116 includes a right drive sprocket 1161 mounted on the drive shaft of the right drive motor 114, and a right driven sprocket 1162 mounted on the right drive sprocket 1121. The right drive sprocket 1161 is connected to the right driven sprocket 1162 via a right drive chain (not shown in the figure). Chain drive provides a simple structure, low cost, and stable operation.

[0057] Furthermore, to prevent the changing tool from being damaged or overturned when it encounters an obstacle or the end of the track while moving along the looper track, the left drive motor 113 and the right drive motor 114 continue to drive the left travel wheel set 111 and the right travel wheel set 112 respectively. Therefore, in this embodiment, it is preferable that touch sensors (not shown in the figure) are provided on the front and rear sides of the base 10. The touch sensors are electrically connected to the control system. When the touch sensor touches an obstacle or the end of the track, the control system can control the traveling mechanism to stop moving based on the touch signal of the touch sensor, that is, control the left drive motor and the right drive motor to stop driving the left travel wheel set and the right travel wheel set to rotate.

[0058] Furthermore, such as Figures 5 to 6 As shown, in this embodiment, the base 10 includes a traveling frame 101 and a transfer trolley 14. Specifically, the traveling frame 101 is provided with a guide rail, which extends in a direction perpendicular to the movement of the base 10. The transfer trolley 14 is disposed on the guide rail and can move along the guide rail, that is, it can move in the left and right direction, i.e., it can move towards the left or right side of the looper track 50. Correspondingly, the rotating platform is rotatably disposed on the transfer trolley 14. With this structural design, when disassembling and hoisting the idlers 510 located on both sides of the looper track 50 and installing new idlers, the transfer trolley 14 can drive the rotating platform and the hoisting mechanism disposed on the rotating platform to move left and right, i.e., it can move towards the left or right side of the looper track 50. Therefore, it is more convenient to replace the idlers 510 located on the left and right sides of the looper track 50.

[0059] Furthermore, such as Figure 5 and Figure 6As shown, in this embodiment, the traveling frame 101 includes a front channel steel 1011 and a rear channel steel 1012. The U-shaped groove on the front channel steel 1011 forms a front guide rail, and the U-shaped groove on the rear channel steel 1012 forms a rear guide rail. The transfer trolley 14 includes a frame 141 and a third drive device. The first end of the frame 141 is rotatably provided with a drive shaft 1411, and both ends of the drive shaft 1411 are provided with drive rollers 1411a. The second end of the frame 141 is rotatably provided with a driven shaft 1412, and both ends of the driven shaft 1412 are provided with driven rollers 1412a. Specifically, the drive rollers 1411a at both ends of the drive shaft 1411 are respectively arranged in the front guide rail and the rear guide rail. Similarly, the driven rollers 1412a at both ends of the driven shaft 1412 are also respectively arranged in the front guide rail and the rear guide rail. The third drive device is used to drive the drive shaft 1411 to rotate. During operation, the drive shaft 1411 is driven to rotate by the third drive device. The drive shaft 1411 then drives the drive rollers 1411a located at both ends to move along the front guide rail and the rear guide rail respectively, thereby realizing the movement of the transfer trolley 14 in the left and right directions.

[0060] Specifically, in this embodiment, a drive sprocket is fixedly mounted on the drive shaft 1411, and the third drive device is specifically a third drive motor 142, which is connected to the drive shaft 1411 via chain drive. The third drive motor 142 also controls the system's electrical connection.

[0061] Furthermore, such as Figure 4 As shown, in this embodiment, the rotating platform includes a driven gear 121 rotatably mounted on the base 10. The diameter of the driven gear 121 extends horizontally. The support rod 21 is fixedly mounted on the driven gear 121. The second driving device includes a second drive motor 122, and a driving gear 1220 is mounted on the drive shaft of the second drive motor 122. The driving gear 1220 meshes with the driven gear 121. During operation, when it is necessary to rotate the hoisting mechanism, the second drive motor 122 drives the driving gear 1220 to rotate. The driving gear 1220 drives the driven gear 121 to rotate synchronously, and then the driven gear 121 drives the hoisting mechanism fixedly mounted on it to rotate, thereby realizing the rotation of the hoisting mechanism.

[0062] Furthermore, to prevent the power cord from being twisted due to excessive rotation of the lifting mechanism caused by the rotating platform, preferably, in this embodiment, a limit switch (not shown in the drawings) is provided on the base. This limit switch is electrically connected to the control system. By setting this limit switch, the angle of rotation of the lifting mechanism driven by the rotating platform can be limited. When the lifting mechanism touches the limit switch, the limit switch feeds back a touch signal to the control system. Based on the touch signal sensed by the limit switch, the control system promptly controls the second drive motor 122 to stop driving.

[0063] Furthermore, such as Figure 3 and Figure 5 As shown, in this embodiment, the boom 22 includes a main boom 221 and an auxiliary boom 222. The first end of the main boom 221 is connected to the support rod 21. The auxiliary boom 222 passes through the main boom 221 and protrudes from the second end of the main boom 221, and the auxiliary boom 222 is telescopic relative to the main boom 221. This structural design allows the lifting mechanism to be applied to a wider range of applications; that is, in actual use, the length of the boom 22 can be controlled according to the required lifting distance, making it more versatile.

[0064] Specifically, such as Figure 5 As shown, in this embodiment, a plurality of first pin holes 2210 are spaced apart on the main boom 221, and these first pin holes 2210 are spaced apart along the length direction of the main boom 221. Correspondingly, a plurality of second pin holes are provided on the auxiliary boom 222, and pins 223 are inserted into the first pin holes 2210 and the second pin holes, thereby fixing the auxiliary boom relative to the main boom 221. When the auxiliary boom needs to extend or retract relative to the main boom, the second pin holes on the auxiliary boom 222 are respectively connected to the plurality of first pin holes spaced apart along the length direction of the main boom 221, thereby realizing the extension length of the auxiliary boom relative to the main boom. The structure is simple.

[0065] Specifically, in this embodiment, a pulley is rotatably provided at the second end of the boom, i.e., the end of the auxiliary boom. The first end of the lifting rope 231 extends downward past the pulley. When lifting the idler roller, the idler roller needs to be manually secured by the hook 2311 at the first end of the lifting rope 231. Then, the winch 23 is driven to rotate by the first drive device, thereby lifting the idler roller. Specifically, in this embodiment, the first drive device is a first drive motor 24.

[0066] Furthermore, the control system is equipped with a wireless transmission module, which enables communication with a remote control terminal. This allows for remote operation of the tooling changer via the remote control terminal, preventing operators from being too close to the work site and thus ensuring personal safety.

[0067] In summary, the new invention's switchable swing gate roller replacement fixture significantly reduces manpower input and saves labor costs. Assuming an 8-hour workday and a labor cost of 500 yuan per day, and the pickling and rolling mill requires approximately 20 roller replacements per month, then an average of 240 rollers need to be replaced annually. Before this fixture, roller handling time was: 5 workers * 0.5 hours = 2.5 hours, totaling 0.3 workdays; roller installation time was: 5 workers * 1 hour = 5 hours, totaling 0.6 workdays. The total annual time required is 240 rolls * 0.9 man-days = 216 man-days, with a calculated cost of 216 man-days * 500 yuan / man-day = 108,000 yuan. However, by using the tooling of this invention, the entire roll-changing operation only requires 1 hour, and can be completed by 4 people, i.e., 0.5 man-days. The calculated cost is 0.5 man-days * 240 rolls * 500 yuan / man-day = 60,000 yuan. The direct benefit (10,000 yuan / year) is 108,000 yuan - 60,000 yuan = 48,000 yuan, meaning approximately 48,000 yuan can be saved annually. Simultaneously, it removes personnel from hazardous working environments, significantly reducing safety risks and greatly improving operational efficiency. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial application value.

[0068] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
