Description

Technical Field

[0001] This utility model relates to the technical field of roller changing vehicles, and in particular to a track-type roller changing vehicle for a cleaning section. Background Technology

[0002] The track-mounted cleaning section roll changing car is a special equipment used for online replacement of rolls in the cleaning section of a steel rolling production line. Its core function is to achieve rapid and accurate replacement of old and new rolls through a track-mounted walking system, thereby improving production efficiency and reducing labor costs.

[0003] The prior art Chinese utility model patent with application number CN202422202532.5 relates to a roller changing trolley for a phosphorus crusher, including a roller changing trolley frame, a roller changing trolley base, a threaded rod, gears, a limit plate, a throttle, a fixing sleeve, and a plug-in slot, which enables the roller changing trolley frame to rise and fall when the roller changing trolley base rotates.

[0004] However, the above-mentioned device can only load a limited number of rollers in actual use and does not have the ability to continuously change rollers for multiple sets of equipment, consuming a lot of time in the process of loading and unloading rollers. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a track-type roller changing car for cleaning sections, which improves the practicality of the device by switching the positions of multiple sets of rollers through a drive device, providing support for both ends of the rollers through a bearing device, and sending the rollers into or out of the equipment through an auxiliary device.

[0006] This utility model discloses a track-type cleaning section roller changing vehicle; it includes a drive unit, a support unit, and an auxiliary unit. The support unit is mounted on the drive unit, and the auxiliary unit is mounted on the drive unit. The drive unit switches the positions of multiple sets of rollers, the support unit provides support for both ends of the rollers, and the auxiliary unit feeds the rollers into or out of the equipment, thus improving the practicality of the device.

[0007] Preferably, the drive device includes a frame, guide rollers, main supports, bearings, annular support frames, annular grooves, transmission belts, and pulleys. Multiple sets of guide rollers are arranged on the lower end face of the frame, and a set of main supports is arranged on the front and back of the upper end face of the frame. Two sets of annular support frames are connected to the inner sides of the two sets of main supports via a set of bearings. Annular grooves are provided on the sides of the annular support frames. A pulley is mounted on the lower inner side of the main supports via a bracket. A synchronous motor is installed outside the supports, controlled by a PLC controller. The output end of the drive motor is connected to the pulley, and a transmission belt is fitted onto the pulley and the annular groove. Activating the synchronous motor on the supports transmits power to the pulley, causing it to rotate. The pulley and transmission belt work together to rotate the main body of the annular support frame, thereby switching the positions of multiple support devices to facilitate the feeding of different replacement rollers onto the auxiliary device.

[0008] Preferably, the support device includes a turntable frame, a support bearing, a U-shaped support frame, and a welded wear-resistant layer. Multiple turntable frames are evenly arranged on the inner side of the annular support frame. The turntable frames are connected to the inner side of the annular support frame through the support bearing. A U-shaped support frame is provided on the inner side of the turntable frame, and a welded wear-resistant layer is provided on the upper part of the inner side of the U-shaped support frame. The U-shaped support frame provides limiting support for the end of the replacement roller, and together with the U-shaped support frames on both sides of the annular support frame, the replacement roller is supported. The support bearing enables the turntable frame to rotate, preventing the turntable frame from tilting during the rotation of the drive device and causing the replacement roller to fall off. The welded wear-resistant layer reduces scratches and wear on the U-shaped support frame during the loading and unloading of the replacement roller, improving the practicality of the device.

[0009] Preferably, it also includes a bearing roller, and multiple sets of bearing rollers are evenly arranged on the bottom inner side of the U-shaped bearing frame; by the multiple sets of bearing rollers arranged on the bottom inner side of the U-shaped bearing frame, the wear of the replacement roller itself in the U-shaped bearing frame is reduced, and it is convenient to manually rotate the replacement roller to inspect the surface of the replacement roller, thereby improving the stability of the device.

[0010] Preferably, the auxiliary device includes a lifting electric cylinder, a lifting platform, a support frame, supporting guide rods, and idlers. The lifting electric cylinder is installed at the lower part of the main support. The front and rear parts of the lifting platform are located inside the two sets of main supports, and the moving ends of the two sets of lifting electric cylinders are connected to the lower end faces of the two sets of lifting platforms. The support frame is located inside the lifting platform, and multiple sets of supporting guide rods are horizontally arranged inside the lifting platform. The supporting guide rods pass through the lower part of the support frame via linear bearings. Multiple sets of idlers are horizontally installed in the support frame, and multiple sets of drive motors are evenly arranged on the side of the support frame. Each set of drive motors is connected to a set of idlers. The height of the support frame is adjusted by controlling the extension of the lifting electric cylinder. The idlers support the replacement rollers, and the idlers connected to drive motors facilitate the transportation of the replacement rollers. The multiple sets of supporting guide rods on the lifting platform enable the support frame to move horizontally within the lifting platform, thus facilitating the adjustment of its position to adapt to different replacement roller installation positions and improving the practicality of the device.

[0011] Preferably, the device also includes a limiting electric cylinder and a limiting plate. A limiting electric cylinder is installed on the upper side of the main support, and a limiting plate is installed on the side of the U-shaped support frame. The limiting electric cylinder can intercept the limiting plate after it extends. By controlling the extension of the limiting electric cylinder to drive the rotation, the limiting plate on the U-shaped support frame is intercepted and limited. As the annular support frame continues to rotate, the turntable frame and the U-shaped support frame are restricted and cannot adjust their own horizontal state, thus tilting over. The support rollers in the U-shaped support frame are tilted into the support frame. Before tilting, the position of the support frame needs to be adjusted so that the support frame is close to the area where the limiting electric cylinder is located to prevent the replacement roller from falling out. This facilitates the delivery of different replacement rollers to the auxiliary device for installation, improving the practicality of the device.

[0012] Preferably, the device also includes a lead screw, a dual-output reducer, and a motor. A lead screw is installed on the side of the lifting platform, and a motor is installed on the lead screw. A set of lead screws is horizontally arranged at the front and rear of the lifting platform. The two output ends of the dual-output reducer are connected to the two sets of lead screws respectively. The lead screws are connected to the lower part of the support frame through nuts. When the motor is turned on, the power is transmitted to the two sets of lead screws through the dual-output reducer, thereby driving the lead screws to rotate. The rotating lead screws drive the support frame to move laterally, thereby actively adjusting the position of the support frame and improving the practicality of the device.

[0013] Preferably, it also includes a storage battery and a protective baffle. The storage battery is installed at the bottom of the frame, and the protective baffle is installed on the upper surface of the support frame away from the limit electric cylinder. The storage battery provides temporary power to the electrical components of the equipment, and the protective baffle intercepts and limits the replacement roller that is tilted out of the U-shaped support frame, preventing the replacement roller from falling out of the support frame due to its own inertia, thus improving the practicality of the device.

[0014] Compared with the prior art, the advantages of this utility model are: the position of multiple sets of rollers is switched by the driving device, the rollers are supported at both ends by the bearing device, and the rollers are fed into or out of the equipment by the auxiliary device, which improves the practicality of the device.

The support rods 17 pass through the lower part of the support frame 16 through linear bearings. Multiple sets of rollers 18 are horizontally installed in the support frame 16. Multiple sets of drive motors are evenly arranged on the side of the support frame 16. The multiple sets of drive motors are respectively connected to the multiple sets of rollers 18. It also includes a limit electric cylinder 19 and a limit plate 20.

As the annular support frame 5 continues to rotate, the turntable frame 9 and the U-shaped support frame 11 become restricted and unable to adjust their horizontal position, causing them to tilt. This tilts the support rollers in the U-shaped support frame 11 into the support frame 16. Then, the extension of the lifting electric cylinder 14 is controlled to adjust the height of the support frame 16. Finally, the motor 23 is turned on to transmit power through… The dual-output reducer 22 transmits power to two sets of lead screws 21, which in turn drive the lead screws 21 to rotate. The rotating lead screws 21 drive the support frame 16 to move laterally, thereby actively adjusting the position of the support frame 16. Then, in conjunction with the drive motor on the support frame 16, the idler roller 18 is driven to rotate, and the replacement roller is sent to the equipment installation position. Before sending the replacement roller, the position of the support frame 16 is adjusted so that the support frame 16 is aligned with the roller to be replaced.
