DETAILED DESCRIPTION

[0041] In order to make the skilled in the art to which the present application belongs more clearly understand the present application, the technical scheme of the present application will be described in detail below with specific embodiments in conjunction with the accompanying drawings.

[0042] In the embodiments of the present application, as shown in the drawings, the loop ground roller replacement device comprises a walking trolley 1, a clamping assembly 2 and a control system 3; wherein, Figure 1

[0043] The clamping assembly 2 is arranged on the walking trolley 1, and the walking trolley 1 can move along the track of the inlet loop;

[0044] The control system 3 is signal connected with the walking trolley 1 and the clamping assembly 2, and is used for controlling the actions of the walking trolley 1 and the clamping assembly 2.

[0045] When the loop ground roller in the inlet loop cannot continue to complete the support and conveying work of the steel strip due to serious wear, the worker can use the loop ground roller replacement device to send the new loop ground roller to the replacement position, and hoist the seriously worn loop ground roller to the walking trolley 1 through the clamping assembly 2, at the same time, hoist the new loop ground roller to the installation position of the loop ground roller for installation, so as to complete the replacement of the loop ground roller.

[0046] Specifically, the worker can operate the control system 3 to control the action of the walking trolley 1, so that the walking trolley 1 moves to the storage position of the loop ground roller, and uses the clamping assembly 2 on the walking trolley 1 to hoist the new loop ground roller to the walking trolley 1, and then continues to control the walking trolley 1 to move along the track of the inlet loop through the control system 3, so as to send the new loop ground roller to the position of the seriously worn loop ground roller (replacement position);

[0047] At this time, the worker operates the control system 3 to control the action of the clamping assembly 2, and uses the clamping assembly 2 to hoist the seriously worn loop ground roller to the walking trolley 1, and then hoists the new loop ground roller loaded on the walking trolley 1 to the installation position of the loop ground roller for installation;

[0048] ​Then, the staff continues to operate the control system 3, and the walking trolley 1 is used to send the seriously worn looped ground roller to the waste storage place, so as to complete the whole looped ground roller replacement process; the looped ground roller replacement device can effectively reduce the labor intensity during the replacement of the looped ground roller, and reduce the probability of mechanical injury caused by the collision of the looped ground roller, so that the replacement of the looped ground roller is more relaxed and convenient, and the replacement efficiency of the looped ground roller is improved.

[0049] In some embodiments, the clamping assembly 2 described above comprises a driving part 21 and a clamping part 22, see Figure 3 The control system 3 described above is in signal connection with the driving part 21 and the clamping part 22; wherein,

[0050] The driving part 21 is arranged on the walking trolley 1;

[0051] The clamping part 22 is arranged at the action end of the driving part 21, the control system 3 can control the driving part 21 to act, so as to drive the clamping part 22 to act towards the position close to or away from the looped ground roller, and the clamping part 22 can be controlled to act by the control system 3, so as to control the clamping part 22 to tighten or loosen the looped ground roller, so as to easily complete the carrying of the ground roller and reduce the labor intensity of the replacement of the looped ground roller.

[0052] In some embodiments, the driving part 21 described above comprises a rotating device 211, a lifting device 213 and a telescopic device 212, and the control system 3 described above is in signal connection with the rotating device 211, the lifting device 213 and the telescopic device 212; wherein,

[0053] The rotating device 211 is arranged on the walking trolley 1, and the action end of the rotating device 211 rotates around the first direction;

[0054] The telescopic device 212 is arranged at the action end of the rotating device 211, and the action end of the telescopic device 212 moves along the second direction;

[0055] The lifting device 213 is arranged at the action end of the telescopic device 212, and the action end of the lifting device 213 moves along the first direction; in this embodiment, the first direction is different from the second direction, and the first direction is perpendicular to the horizontal plane, and the rotating shaft of the rotating device 211 is also perpendicular to the horizontal plane, and the action end of the rotating device 211 can rotate 360° around the rotating shaft thereof;

[0056] The second direction described above is perpendicular to the first direction, that is, the second direction is parallel to the horizontal plane, and the action end of the telescopic device 212 can drive the lifting device 213 to act towards the direction close to / away from the walking trolley 1;

[0057] The action end of the lifting device 213 can act along the first direction towards the direction close to or away from the looped ground roller, see Figure 1 .

[0058] When hoisting the worn looped ground roller, the worker can control the rotation device 211 and the telescopic device 212 to act through the control system 3, adjust the position of the lifting device 213 to the upper side of the worn looped ground roller through the rotation and telescopic action, and then control the lifting device 213 to act through the control system 3, so that the action end of the lifting device 213 approaches the worn looped ground roller until the clamping end of the clamping part 22 can clamp the worn looped ground roller, and then control the clamping part 22 to act through the control system 3, so as to clamp and fix the worn looped ground roller;

[0059] Subsequently, the worn looped ground roller is lifted up to a height higher than the height of the bearing surface of the walking trolley 1 through the action of the lifting device 213 controlled by the control system 3, and then the worn looped ground roller is hoisted to the bearing surface of the walking trolley 1 through the rotation and telescopic action of the rotation device 211 and the telescopic device 212 controlled by the control system 3, and then the worn looped ground roller is lowered.

[0060] After the worn looped ground roller is lowered, the telescopic device 212, the lifting device 213 and the clamping part 22 are controlled to act through the control system 3, the prepared new looped ground roller is hoisted, and the new looped ground roller is hoisted to the installation position through the cooperation of the rotation device 211, the telescopic device 212 and the lifting device 213, and then the clamping part 22 is controlled to act to release the new looped ground roller, so as to complete the transportation and carrying of the looped ground roller.

[0061] It should be noted that the transportation and carrying steps of the looped ground roller are not limited to the above method, and can be adjusted according to the actual situation during specific operation.

[0062] In some embodiments, the clamping part 22 includes a cross beam 221 and a ground roller clamp 222, as shown in Figure 3 and Figure 4 The control system 3 is signal connected with the ground roller clamp 222; wherein

[0063] The cross beam 221 is arranged at the action end of the driving part 21;

[0064] The number of the ground roller clamp 222 is two, and the two ground roller clamps 222 are arranged near the two ends of the cross beam 221 respectively; the two ground roller clamps 222 are clamped at the two ends of the looped ground roller respectively, so that the clamping part 22 can better complete the clamping and fixing of the ground roller. Preferably, the clamping surface of the ground roller clamp 222 is provided with an anti-skid part, which can increase the roughness of the clamping surface of the ground roller clamp 222, so as to increase the friction force between the contact surface of the ground roller clamp 222 and the looped ground roller when the ground roller clamp 222 clamps the looped ground roller, thereby effectively avoiding the situation that the looped ground roller slips off the ground roller clamp 222, so as to improve the safety of the looped ground roller replacing device during use.

[0065] In some embodiments, the clamping part 22 further comprises an identification positioning device 223, see Figure 4 The control system 3 described above is in signal connection with the identification positioning device 223, and the identification positioning device 223 can be turned on / off through the control system 3; the identification positioning device 223 is arranged on the cross beam 221, and the workers can better position the position of the looped ground roller through the identification positioning device 223, so as to quickly complete the clamping and replacement of the looped ground roller, thereby further improving the replacement efficiency of the looped ground roller.

[0066] In some embodiments, the identification positioning device 223 described above comprises a positioning lamp; wherein,

[0067] The cross-sectional shape of the light column projected by the positioning lamp matches the pattern of the orthographic projection of the looped ground roller; when the looped ground roller is located within the range of the light column projected by the positioning lamp, as Figure 3 indicated, it indicates that the clamping part 22 is located above the looped ground roller, at this time, the workers control the driving part 21 to act through the control system 3, so that the clamping part 22 moves close to the looped ground roller, so as to quickly hoist the looped ground roller.

[0068] Of course, when the distance between the clamping part 22 and the looped ground roller is large, the light shadow area on the ground projected by the positioning lamp will be larger than the pattern area of the orthographic projection of the looped ground roller, so that there may be some deviation between the position of the ground roller clamp 222 on the clamping part 22 and the position of the looped ground roller, and the workers may need to make some fine adjustment to the position of the clamping part 22 during operation, so that the ground roller clamp 222 can accurately clamp the looped ground roller.

[0069] It should be noted that even if the positioning lamp is used, there may be some deviation between the position of the ground roller clamp 222 and the position of the looped ground roller, but the positioning effect is better than that of the workers only by feeling, which can effectively improve the replacement efficiency of the looped ground roller.

[0070] In some embodiments, the identification positioning device 223 described above comprises an image collector and a display; wherein,

[0071] The image collector is a camera, the image collector is arranged on the cross beam 221, the display is arranged on the control system 3, and the image collector and the display are in signal connection; the workers can check the corresponding position of the clamping part 22 through the display, so as to more quickly complete the hoisting of the looped ground roller.

[0072] It should be noted that the above-mentioned pattern collector and display in the identification positioning device 223 can facilitate the positioning of the looped ground roller in the high layer (the installation position higher than the standing position of the staff), so that the looped ground roller replacing device can replace the looped ground roller on any layer of the swing door in the cold rolling continuous production line, thereby making the use of the looped ground roller replacing device more convenient.

[0073] In some embodiments, the number of clamping assemblies 2 is two groups, see Figure 1 The two groups of clamping assemblies 2 are respectively arranged near the two ends of the walking trolley 1.

[0074] In some embodiments, the above-mentioned walking trolley 1 includes a frame 11, a driving motor 12 and a roller 13, see Figure 2 The control system 3 is signal connected with the driving motor 12; wherein,

[0075] The frame 11 is provided with a support frame 14 for placing the looped ground roller, in the embodiment, the upper end surface of the support frame 14 is provided with a groove, the diameter of the groove is equal to the diameter of the looped ground roller, when the looped ground roller is placed in the groove on the support frame 14, the support frame 14 can limit the rolling of the looped ground roller, so as to avoid the situation that the looped ground roller rolls on the walking trolley 1 and collides and damages;

[0076] The roller 13 is rotationally arranged on the frame 11;

[0077] The driving motor 12 is arranged on the frame 11, the driving motor 12 is drivingly connected with the roller 13, the rotation of the roller 13 is controlled by the driving motor 12, and the movement of the walking trolley 1 is realized.

[0078] Through the above-mentioned embodiments, the present application has the following advantages or benefits:

[0079] 1) The control system 3 in the looped ground roller replacing device provided by the present application can control the actions of the clamping assembly 2 and the walking trolley 1, so as to easily complete the transportation and handling of the looped ground roller, through the cooperation of the clamping assembly 2 and the walking trolley 1, the labor intensity during replacing the looped ground roller can be effectively reduced, and the probability of mechanical injury caused by collision of the looped ground roller can be reduced, thereby making the replacement of the looped ground roller more easy and convenient, and improving the replacement efficiency of the looped ground roller.
