Description

Technical Field

[0001] The utility model relates to the technical field of wire transmission equipment, in particular to a wire coil walking line steering device. Background Art

[0002] With the technological upgrading of wire production line equipment in the metallurgical industry, the weight of the whole coil of wire has gradually increased from less than 1.4t to 2.7t and above. Due to the increase in coil weight, the loose coil height has increased to more than 5 meters. The increase in height has caused the center of gravity to become higher and the stability to become worse. The original traditional double-core rod coiling method is no longer suitable for large-scale heavy coil production. The current equipment has been gradually upgraded to a coil core rack method. The transmission of the coil core rack requires the use of a matching wire roller bed mechanism.

[0003] At present, most rotary roller beds use reduction motors for gear transmission to achieve the purpose of rotating the wire roller bed. Since rotary roller beds are mostly used in heavy industrial environments such as steel mills, there are many impurities, particles and dust in the air, and the gear transmission requires medium lubrication, which increases the maintenance cost of the equipment.

The device drives the driving gear to rotate through the rotating motor, and then drives the rotating roller bed to turn through the meshing of the driving gear and the tooth portion; during the driving process, since the power needs to pass through the gear transmission, the driving efficiency is low, and the driving gear is used for a long time and is easy to wear, and needs to be repaired and replaced frequently, and the gear transmission requires medium lubrication, which increases the maintenance cost, and the lubricating medium will cause environmental pollution.

[0023] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0024] Embodiment 1:

[0025] See also Figure 1 , Figure 2 The utility model provides a technical solution: it includes a rotating table 1, a driving motor 2 arranged on the rotating table 1, and a conveying roller bed 3 arranged above the rotating table 1, the rotating table 1 is fixedly connected to a slewing support bearing 4 for driving the conveying roller bed 3 to rotate, and the conveying roller bed 3 is fixedly connected to the outer ring of the slewing support bearing 4; the rotating table 1 is provided with an active synchronous pulley 5 connected to the driving motor 2, the upper fastening sleeve of the slewing support bearing 4 is provided with a driven synchronous pulley 6, and a synchronous belt 7 is jointly sleeved on the active synchronous pulley 5 and the driven synchronous pulley 6; the rotating table 1 is provided with a locking device for locking the rotation angle of the conveying roller bed 3.

[0026] A circuit box with a control panel is provided on the rotating table 1, and the driving motor 2 is electrically connected to the control panel. The staff operates on the control panel to start and stop the driving motor 2, and the driving motor 2 adopts a reduction motor.

[0027] See also Figure 1 , Figure 2The locking device includes a support plate 81 fixedly connected to the rotating table 1, an arc plate 82 slidably connected to the support plate 81, and a driving assembly for driving the arc plate 82 to move, wherein the arc plate abuts against the outer surface of the synchronous belt 7. The surface of the arc plate 82 is tightly covered with striped rubber, which increases the friction and reduces the wear of the synchronous belt 7.

[0028] The driving assembly includes a first fixing plate 811 fixedly connected to the support plate 81, a pushing screw 812 threadedly penetrated through the first fixing plate 811, and a first spring 813 for connecting the first fixing plate 811 and the arc plate 82. The end of the pushing screw 812 is fixedly connected to a rotating handle 814.

[0029] When the device is in use, when the wire roll conveying route needs to be changed, the staff starts the driving motor 2 through the control panel, and the driving motor 2 drives the active synchronous pulley 5 to rotate, which in turn drives the driven synchronous pulley 6 to rotate through the synchronous belt 7. The rotation of the driven synchronous pulley 6 drives the outer ring of the slewing support bearing 4 to rotate, thereby realizing a change in the rotation angle of the conveying roller 3; when the rotation angle of the conveying roller 3 is adjusted, the staff rotates the advancing screw 812 through the rotating handle 814, thereby pushing the arc plate 82 to move to the left, squeezing the synchronous belt 7, and thus locking the synchronous belt 7. When the rotation angle of the conveying roller 3 needs to be adjusted again, the staff rotates the rotating handle 814 in the opposite direction. Under the action of the first spring 813, the arc plate 82 is reset, and the locking of the synchronous belt 7 is released. The staff can then operate the control panel.

[0030] Embodiment 2:

[0032] When the device is in use, when the wire roll conveying route needs to be changed, the staff starts the driving motor 2 through the control panel, and the driving motor 2 drives the active synchronous pulley 5 to rotate, which in turn drives the driven synchronous pulley 6 to rotate through the synchronous belt 7. The rotation of the driven synchronous pulley 6 drives the outer ring of the slewing support bearing 4 to rotate, thereby realizing a change in the rotation angle of the conveying roller 3; when the rotation angle of the conveying roller 3 is adjusted, the staff pulls the cam 824, thereby moving the linkage rod 822 to the left to squeeze the synchronous belt 7, thereby locking the synchronous belt 7. When the rotation angle of the conveying roller 3 needs to be adjusted again, the staff pulls the cam 824 in the opposite direction. Under the action of the second spring 825, the arc plate 82 is reset to release the lock of the synchronous belt 7, and the staff can then operate the control panel.

[0033] Embodiment 3:

[0034] like Figure 3 , Figure 4 As shown, Example 2 is modified relative to Example 1. The driving assembly includes an electric push rod 9 fixedly connected to the arc plate 82, the electric push rod 9 is fixedly connected to the support plate 81, the electric push rod 9 is electrically connected to the control panel, and other places are in accordance with Example 1.

[0035] When the device is in use, when the wire roll conveying route needs to be changed, the staff starts the driving motor 2 through the control panel, and the driving motor 2 drives the active synchronous pulley 5 to rotate, which in turn drives the driven synchronous pulley 6 to rotate through the synchronous belt 7. The rotation of the driven synchronous pulley 6 drives the outer ring of the slewing support bearing 4 to rotate, thereby realizing the change of the rotation angle of the conveying roller bed 3; when the rotation angle of the conveying roller bed 3 is adjusted, the staff starts the electric push rod 9 through the control panel, and the electric push rod 9 pushes the arc plate 82 to move to the left, thereby locking the synchronous belt 7. When the rotation angle of the conveying roller bed 3 needs to be adjusted again, the staff resets the electric push rod 9 through the control panel, thereby moving the arc plate 82 to the right, releasing the lock on the synchronous belt 7, and then the staff operates the control panel.
