Description

Technical Field

[0001] The utility model relates to the technical field of steel production, in particular to an anti-derailment steel coil conveying device. Background Art

[0002] The anti-derailment coil conveyor is an intermediate mechanical device that transfers the coiled coils from the lifting trolley to the running trolley on the thin slab continuous casting and rolling production line. When the coil conveyor moves to the corresponding position of the lifting trolley, the lifting frame falls, and after the C-hook trolley extends to the bottom of the coil, the lifting frame performs a lifting movement, the coil is lifted, the C-hook trolley retracts, and the coil conveyor moves as a whole to the running trolley. Because the axis direction of the coil in the lifting trolley is perpendicular to the moving direction of the coil conveyor, the lifting trolley can normally drop the coil to the predetermined position, and the closest distance between the coil and the coil conveyor is maintained at a gap of about 200 mm, ensuring the normal operation of the coil conveyor without interference. However, when the abnormal shape of the steel coil causes the steel coil to accidentally exceed the landing point, the steel coil conveyor will be blocked when it runs over. At this time, the fault phenomenon is that the lifting frame of the steel coil conveyor derails due to the abnormal lateral external force. After the lifting frame derails, an overload alarm is caused, making the equipment unable to continue to be used. The maintenance time is 3-5 hours, resulting in the forced suspension of production and huge losses.

[0025] See also Figures 1 to 3The utility model provides an anti-derailment steel coil conveying device. The anti-derailment steel coil conveying device comprises a frame 1 and a lifting frame 3 installed on the frame 1. The lifting frame 3 comprises a lifting frame 31, a vertical guide rail 33 and a guide wheel seat group composed of a plurality of guide wheel seats, the vertical guide rail 33 is vertically installed on the frame 1, the guide wheel seat group is installed on the lifting frame 31, and the lifting frame 31 is connected to the vertical guide rail 33 through the guide wheel seat group. By installing the vertical guide rail 33 on the frame 1, after the steel coil is moved to the lifting frame 3, the oil cylinder drives the lifting frame 3 to do lifting motion along the vertical guide rail 33 to convey the steel coil to different positions.

[0026] Each of the guide wheel seats 35 includes a main body 351 fixedly mounted on the lifting frame 31 and a rolling wheel 353 mounted on the main body 351. One end of the main body 351 is protruded toward the vertical guide rail 33 and is provided with two clamping parts 352 for limiting the vertical guide rail 33. The rolling wheel 353 is mounted on the clamping parts 352 and forms a rolling connection with both sides of the vertical guide rail 33. The two protruding clamping parts 352 of the guide wheel seat 35 limit the vertical guide rail 33 in the middle, and the rolling wheel 353 arranged on the clamping parts 352 forms a rolling connection with both sides of the vertical guide rail 33, so that the guide wheel seat 35 maintains the positional relationship between the lifting frame 31 and the vertical guide rail 33 without affecting the lifting movement of the lifting frame 3, so that the lifting frame 3 will not derail under the action of external force, and can adapt to more complex working conditions, stabilize the production rhythm, reduce the probability of maintenance and shutdown, reduce production costs, and reduce labor intensity.

[0027] Specifically, in this embodiment, the lifting frame 31 includes a vertical frame 311, a lower horizontal frame 313, and a steel coil support 315 fixed on the lower horizontal frame 313. The vertical frame 311 and the lower horizontal frame 313 are respectively connected to the vertical guide rail 33 through the guide wheel seat 35. During the lifting movement of the lifting frame 31, the rolling wheel 353 on the guide wheel seat 35 rolls along the vertical guide rail 33, and the clamping part 352 on the guide wheel seat 35 is located on both sides of the vertical guide rail 33, so that the lifting frame 31 will not derail under the impact of external force.

[0028] The guide wheel seat 35 fixed on the vertical frame 311 is fixedly connected to the vertical frame 311 through the connecting bracket 9. It can be understood that the connecting bracket 9, as an intermediate connecting component, can connect components at different positions and improve the connectivity between components.

[0029] In detail, a through hole is opened on one side of the lower cross frame 313 , and the guide wheel seat 35 fixed on the lower cross frame 313 passes through the through hole to be connected with the vertical guide rail 33 .

[0030] Furthermore, one end of the steel coil support 315 close to the steel coil transport direction gradually narrows from the center of the steel coil support 315 to both sides to form a clearance chamfer 317. Furthermore, there are two clearance chamfers 317, and the two clearance chamfers 317 are symmetrically arranged along the center line of the steel coil support 315. When the lifting frame 3 collides, the two clearance chamfers 317 can cause the steel coil to slip axially, and the clearance chamfers can push the steel coil back to a safe position along its axial direction, reducing the loss of the steel coil, and can also reduce the collision force of the steel coil, thereby reducing the derailment probability of the lifting frame 3. Therefore, the simultaneous arrangement of the guide wheel seat assembly and the clearance chamfers 317 greatly reduces the derailment probability of the lifting frame 3.

[0031] In another embodiment, the bottom of the frame 1 is also mounted on the transverse guide rail 5, and reinforced guide wheel seats 735 are installed at both ends of the bottom of the frame 1. The frame 1 can move along the transverse guide rail 5, and the provision of the reinforced guide wheel seats 735 can reduce the probability of derailment of the bottom of the frame 1.

[0032] Furthermore, the reinforced guide wheel seat 735 has the same structure as the guide wheel seat 35. The reinforced guide wheel seat is also composed of a square main body and a rolling wheel installed on the main body.

[0033] Specifically, in this embodiment, the guide wheel seat 35 is connected to the lower cross frame 313 by bolts. Connecting the guide wheel seat and the lower cross frame 313 by bolts is more convenient for disassembly and assembly. Of course, in other embodiments, the guide wheel seat 35 and the lower cross frame 313 can also be fixed by welding.

[0034] The anti-derailment steel coil conveying device provided by the utility model is provided with a guide rail installed on the frame 1, so that after the steel coil of the lifting frame 31 is moved onto the lifting frame 3, the lifting frame 3 performs lifting motion along the vertical guide rail 33 to convey the steel coil to different positions. At the same time, the vertical guide rail 33 is limited in the middle by the two protruding clamping parts 352 of the guide wheel seat 35, and the rolling wheel 353 arranged on the clamping part 352 is formed with the vertical guide rail 33 to form a rolling connection, so that the guide wheel seat 35 maintains the positional relationship between the lifting frame 31 and the vertical guide rail 33 without affecting the lifting motion of the lifting frame 3, so that the lifting frame 3 will not derail under the action of external force, and can adapt to more complex working conditions, maintain a stable production rhythm, reduce the probability of maintenance and shutdown, reduce production costs, and reduce labor intensity.

[0035] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
