Description

Technical Field

[0001] The invention belongs to the technical field of steel strip transfer, and in particular relates to a transfer device for cold-rolled steel strip processing. Background Art

[0002] Cold-rolled steel strip coils are made by winding cold-rolled steel strips of a certain width into a coil shape for easy transportation and processing. In the production process of cold-rolled steel strip coils, a larger width steel strip is cut longitudinally into smaller width steel strips by machinery, and continuous winding is performed while continuous cutting. When the coil is wound to a certain diameter, a disc-shaped steel strip coil is formed.

[0003] At present, when cold-rolled steel strip coils are transferred and transported, forklifts or electric hoists are usually used for transfer due to their large size and weight. However, forklifts and electric hoists are large-scale transfer equipment with limited transfer range. In addition, during the transfer of cold-rolled steel strip coils, manual assistance is still required to install the cold-rolled steel strip coils on the connection parts of the forklifts or electric hoists, which is complicated to operate, resulting in low transfer efficiency and prone to safety accidents. Summary of the invention

[0004] In order to overcome the above-mentioned defects, the present invention provides a transfer device for cold-rolled steel strip processing, which solves the problem of using a forklift or an electric hoist for transfer. However, the forklift and the electric hoist are large-scale transfer equipment with a limited transfer range. In addition, in the process of transferring the cold-rolled steel strip coils, human assistance is still required to install the cold-rolled steel strip coils on the connecting part of the forklift or the electric hoist, which is complicated to operate, resulting in low transfer efficiency and prone to safety accidents.

[0005] The objects of the present invention are:

[0006] During the process of the two supporting components approaching each other, the guide roller in the moving seat can contact the outer arc surface of the cold-rolled steel strip coil. As the two moving seats continue to approach each other, the guide roller in the moving seat can squeeze the cold-rolled steel strip coil. Since the guide roller is installed obliquely in the inclined groove, the guide rollers on both sides can lift the cold-rolled steel strip coil.

[0007] The bottom of the cold-rolled steel strip coil is off the ground and located in the inclined groove. The two sides of the inner wall of the inclined groove can limit the cold-rolled steel strip coil to prevent the cold-rolled steel strip coil from slipping off the two moving seats. The cold-rolled steel strip coil can be transferred by pushing the counterweight base by the handle. The traditional method of using a forklift or an electric hoist is abandoned. The cold-rolled steel strip coil is transferred by the transfer device. There is no need for human assistance to adjust the position of the cold-rolled steel strip coil and carry it into the device, which improves the convenience of operation and the efficiency of transfer, and reduces the probability of safety accidents.

[0008] When the device is bumped, the moving seat will press down the two telescopic rods at the bottom, and the elastic support of the buffer spring can play a role in buffering the moving seat and the cold-rolled steel strip coil. During the vertical movement of the moving seat, it can drive the two slide columns in the limit assembly to slide in the slide groove, and cooperate with the force of the support spring in the slide groove to play a role in buffering and damping the moving seat, thereby preventing the continuous shaking of the moving seat from causing secondary damage to the cold-rolled steel strip coil.

[0009] When the device is pushed to move by the handle, when encountering a road surface with a large height difference, one of the running wheels will contact the protruding part of the road surface and continue to apply thrust to the counterweight base, so that the running wheel will drive the rotating shaft to rotate on the counterweight base through the baffle, so that the running wheel at the top of the baffle can pass over the highest point of the protrusion of the road surface. As the running wheel drives the baffle and the rotating shaft to continue to rotate, the lowest running wheel can be brought out of the protruding part of the road surface, so that all the running wheels can cross the road surface to complete the transfer work of the device. Therefore, the device can be suitable for transportation work on different road surfaces.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 3.

When the device is pushed to move by the handle, when encountering a road surface with a large height difference, one of the running wheels will contact the protruding part of the road surface and continue to apply thrust to the counterweight base, so that the running wheel will drive the rotating shaft to rotate on the counterweight base through the baffle, so that the top running wheel of the baffle can pass over the highest point of the protrusion of the road surface. As the running wheel drives the baffle and the rotating shaft to continue to rotate, the bottom running wheel can be brought out of the protruding part of the road surface, so that all the running wheels can complete the transfer work of the device by crossing the road surface. Therefore, the device can be suitable for transportation work on different road surfaces, making it widely used. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The technical solution of the present application is further described in detail below in conjunction with specific implementation methods.

[0031] like Figure 1-6As shown, the present invention provides a technical solution: a transfer device for processing cold-rolled steel strips, comprising a counterweight base 1, a storage rack 10 is installed on the top of the counterweight base 1, a plurality of partitions 11 are arranged in the storage rack 10, and a handle 12 is installed on one side of the counterweight base 1. The cooperation between the storage rack 10 and the partition 11 is convenient for classifying and placing tools and auxiliary materials for processing, and the setting of the handle 12 is convenient for pushing the counterweight base 1.

[0032] The counterweight base 1 is provided with a cavity 2, and an adjustment assembly 3 is installed in the cavity 2. The adjustment assembly 3 includes a dual-axis motor 301, which is installed in the middle of the cavity 2. The two output shafts of the dual-axis motor 301 are respectively fixedly connected with screw rods 302, and the threads of the two screw rods 302 are in opposite directions. The end of the screw rod 302 away from the dual-axis motor 301 is sleeved with a bearing seat 304, and the bearing seat 304 is installed on one side of the cavity 2. The screw rod 302 is externally threaded with a nut 303, and the nut 303 is externally fixedly connected with a sliding block 305; one side of the counterweight base 1 is provided with two sliding holes 4, and the sliding block 305 is slidably connected in the sliding holes 4.

[0033] The sliding hole 4 limits the sliding block 305 to prevent the nut 303 from rotating synchronously during the rotation of the screw rod 302, thereby improving the stability of the position adjustment of the nut 303; because the threads on the outside of the two screw rods 302 are in opposite directions, the nuts 303 on the outside of the two screw rods 302 can approach each other and drive the two sliding blocks 305 to move synchronously, thereby improving the stability of the sliding block 305 driving the side stop assembly 5 to move.

[0034] The side of the sliding block 305 away from the nut 303 is fixed to the side block assembly 5. The side block assembly 5 includes an extension plate 501. The end of the extension plate 501 is fixed to the sliding block 305. Main universal wheels 502 are respectively installed on both sides of the bottom of the extension plate 501.

[0035] One side of the extension plate 501 overlaps with the support assembly 6, and the support assembly 6 includes a moving seat 601, which overlaps with one side of the extension plate 501. An inclined groove 602 is provided on the moving seat 601, and a plurality of guide rollers 603 are installed on the inner wall of the inclined groove 602. When the cold-rolled steel coil is lifted up, the guide rollers 603 can be driven to rotate, thereby reducing friction and preventing damage to the cold-rolled steel coil during the lifting process; the bottom of the cold-rolled steel coil is off the ground and is located in the inclined groove 602. The two sides of the inner wall of the inclined groove 602 can limit the cold-rolled steel coil and prevent the cold-rolled steel coil from slipping off the two moving seats 601.

[0036] Telescopic rods 604 are respectively installed on both sides of the bottom of the moving seat 601, and a pair of universal wheels 605 are installed at the bottom of the telescopic rods 604. A buffer spring 606 is connected to the outer shell of the telescopic rod 604, and the top of the buffer spring 606 is connected to the bottom of the moving seat 601. Through the mutual cooperation between the telescopic rods 604 and the buffer spring 606, when the device is bumped, the moving seat 601 will press down the two telescopic rods 604 at the bottom, and the elastic support of the buffer spring 606 can play a role in buffering the moving seat 601 and the cold-rolled steel strip coil.

[0037] Among them, the two auxiliary universal wheels 605 at the bottom of the moving seat 601 and the main universal wheel 502 at the bottom of the extension plate 501 can freely change angles, which is convenient for arbitrary adjustment of the angle of the transfer device to meet the needs of multi-directional transfer of cold-rolled steel strip coils.

[0038] The bottom of the support assembly 6 is provided with a limit assembly 7, and two sides of the extension plate 501 are respectively provided with slide grooves 8, and two ends of the limit assembly 7 are respectively installed in the two slide grooves 8. Specifically, the limit assembly 7 includes an ear plate 701, which is fixedly connected to one side of the moving seat 601, and two sides of the ear plate 701 are respectively fixedly connected with slide posts 702, and the top of the slide post 702 is fixedly connected with a stopper 703, and the stopper 703 is slidably connected in the slide groove 8; the outer sleeve of the slide post 702 is connected with a support spring 704, and the top of the support spring 704 is fixed to the bottom of the stopper 703, and the bottom of the support spring 704 is fixedly connected to the bottom of the inner wall of the slide groove 8. The two slide posts 702 can squeeze the support spring 704 during the sliding process in the slide groove 8, and the elastic support of the support spring 704 plays a role in buffering and damping the moving seat 601.

[0039] A transfer assembly 9 is installed on one side of the bottom of the counterweight base 1. The transfer assembly 9 includes two baffles 901, and the two baffles 901 are respectively located at the front and rear sides of the counterweight base 1. The three protruding ends of the baffles 901 are respectively installed with running wheels 903. The middle parts of the two baffles 901 are fixedly connected with a rotating shaft 902, and the rotating shaft 902 is installed through the counterweight base 1. When encountering a road surface with a large height difference, one of the running wheels 903 will contact the protruding part of the road surface, and the running wheel 903 will drive the rotating shaft 902 to rotate through the baffle 901. The upper running wheel 903 can pass over the highest point of the protruding road surface, and can bring the lowest running wheel 903 out of the protruding part of the road surface, so that all running wheels 903 can cross the protruding road surface.

[0040] The working principle of the present invention is:

[0041] When in use, the counterweight base 1 is pushed by the handle 12, so that the counterweight base 1 drives the transfer assembly 9 to move on the ground, and the walking wheels 903 in the transfer assembly 9 roll on the ground, and the two side stop assemblies 5 on the counterweight base 1 are pushed to the two sides of the cold-rolled steel strip coil; by controlling the operation of the dual-axis motor 301 to drive the two screw rods 302 to rotate, the nuts 303 outside the two screw rods 302 can approach each other and drive the two sliding blocks 305 to move, and the sliding blocks 305 drive the support assembly 6 to move through the side stop assembly 5. As the two supporting components 6 approach each other, the guide roller 603 in the moving seat 601 can contact the outer arc surface of the cold-rolled steel strip coil. As the two moving seats 601 continue to approach each other, the guide roller 603 in the moving seat 601 can squeeze the cold-rolled steel strip coil. Since the guide roller 603 is installed obliquely in the inclined groove 602, the guide rollers 603 on both sides can lift the cold-rolled steel strip coil, so that the bottom of the cold-rolled steel strip coil is off the ground and located in the inclined groove 602. The transfer of the cold-rolled steel strip coil can be completed by pushing the counterweight base 1 through the handle 12.

[0042] The two auxiliary universal wheels 605 at the bottom of the moving seat 601 and the main universal wheel 502 at the bottom of the extension plate 501 can freely change their angles, and thus the angle of the transfer device can be arbitrarily adjusted; when the device is bumped, the moving seat 601 will press down the two telescopic rods 604 at the bottom, and through the elastic support of the buffer spring 606, it can play a role in buffering the moving seat 601 and the cold-rolled steel strip coil. During the vertical movement of the moving seat 601, it can drive the two sliding columns 702 in the limiting assembly 7 to slide in the slide groove 8, and cooperate with the force of the support spring 704 in the slide groove 8 to play a role in buffering and damping the moving seat 601. When the device is moved by pushing the handle 12, when encountering a road surface with a large height difference, one of the running wheels 903 will contact the protruding part of the road surface and continue to apply thrust to the counterweight base 1, so that the running wheel 903 will drive the rotating shaft 902 to rotate on the counterweight base 1 through the baffle 901, so that the running wheel 903 at the top of the baffle 901 can pass over the highest point of the protrusion of the road surface. As the running wheel 903 drives the baffle 901 and the rotating shaft 902 to continue to rotate, the lowest running wheel 903 can be brought out of the protruding part of the road surface, so that all the running wheels 903 can cross the road surface to complete the transfer work of the device.
