Description

Technical Field

[0001] The utility model belongs to the technical field of anti-backwarding, and more specifically relates to an anti-backwarding structure for a cooling roller. Background Art

[0002] In steel mill production, the cooling roller conveyor is a core conveying equipment, and its stability is directly related to production safety and efficiency. The existing cooling roller conveyor was not initially designed with a dedicated anti-fallback device. As a result, in the event of an emergency stop or equipment failure, the wire rods on the roller conveyor are prone to slipping and becoming untidy due to the combined effects of the roller conveyor's inclination and the weight of the product. This significantly impacts maintenance personnel when adjusting chains or replacing components, and can easily lead to hand injuries. More importantly, the occurrence of a fallback situation directly affects the final product quality and leads to increased scrap rates. Equipment failures include power outages, cooling chain breakage, and chain link failure.

[0003] Although the following forms of anti-reverse devices have emerged subsequently, such as a structure combining a push rod, a block and a fixed support, the above structure is prone to rapid wear during long-term use and usually needs to be replaced and reinforced in about half a month. This not only increases maintenance costs, but may also cause downtime accidents due to failure to detect wear in time. At the same time, the above device is also accompanied by the problem of high noise, which affects the working environment of the operator. Utility Model Content

[0006] In one possible implementation, the limit swing seat is connected to the outer wall of the frame through a rotating pin, the top of the limit swing seat has a limit surface that is pressed against the side stop block for limiting the position, and the bottom of the limit swing seat has a guide surface that slides with the side stop block, and the guide surface gradually extends upward on the side close to the one-way bearing.

[0008] In some embodiments, the bottom of the limiting groove has an inclined surface that abuts against the guide surface for limiting position, and the inclined surface extends gradually upward on a side close to the cooling roller.

[0009] In a possible implementation, an elastic member is provided between the rotating pin and the position-limiting swing seat, and the elastic member is used to pull the position-limiting swing seat to be limited to the lower end of the position-limiting groove.

Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "several" means two or more, unless otherwise clearly and specifically defined.

[0025] Please also refer to Figures 1 to 5 Now, the anti-reversal structure of the cooling roller provided by the present invention is described. The anti-reversal structure of the cooling roller includes a cooling roller 1, a one-way bearing 2, a side block 3, a limit swing seat 4 and a limit vertical plate 6. The cooling roller 1 is rotatably connected to the frame 8, one end of the cooling roller 1 extends to the outside of the frame 8, the one-way bearing 2 is sleeved on the outer end of the cooling roller 1, the side block 3 is connected to the outer ring of the one-way bearing 2, the limit vertical plate 6 is connected to the side of the frame 8, the limit swing seat 4 is rotatably connected to the side of the limit vertical plate 6 away from the cooling roller 1, and can swing vertically. The limit vertical plate 6 is provided with a limit groove 61 for the limit swing seat 4 to pass through to limit the swing amplitude of the limit swing seat 4. The side block 3 is connected to the limit swing seat 4 by a connecting member 5. The connecting member 5 can break when the one-way bearing 2 is stuck. The limit swing seat 4 can swing upward to avoid the side block 3 when the one-way bearing 2 is stuck, and abut against the side block 3 for limitation when the one-way bearing 2 reverses following the cooling roller 1.

[0026] The anti-reversal structure of the cooling roller provided in this embodiment is compared with the prior art. The side block 3 outside the one-way bearing 2 is connected to the limit swing seat 4 through the connecting piece 5, so that the cooling roller 1 meets the requirement of one-way operation under the action of the one-way bearing 2. When the one-way bearing 2 fails and becomes stuck, the connecting piece 5 can break under the pulling action of the side block 3, and the cooling roller 1 drives the one-way bearing 2 to rotate clockwise synchronously. The side block 3 can push the limit swing seat 4 upward to realize the continued rotation of the cooling roller 1, and then the machine can be shut down for maintenance or replacement. The above structure meets the anti-reversal effect of the one-way bearing 2 in different states such as normal and stuck, ensures the stability of equipment operation, facilitates daily inspection and maintenance, guarantees product quality, and improves production safety.

[0027] For ease of description, the following example illustrates that the cooling roller 1 rotates clockwise as forward rotation and counterclockwise as reverse rotation. In this embodiment, the side block 3 on the outside of the one-way bearing 2 is fixed to the limiting swing seat 4 via a connector 5, so that the outer ring of the one-way bearing 2 is securely fixed. The one-way bearing 2 can cooperate with the cooling roller 1 to rotate clockwise in the forward direction, while the one-way bearing 2 prevents the cooling roller 1 from rotating counterclockwise, thereby achieving an anti-reverse effect on the cooling roller 1 and preventing reverse rotation.

[0028] When the one-way bearing 2 fails and gets stuck, the inner and outer rings of the one-way bearing 2 are relatively fixed, and the inner and outer rings of the one-way bearing 2 keep rotating synchronously with the cooling roller 1. At this time, the cooling roller 1 is difficult to stop in time due to inertia, and the cooling roller 1 will drive the one-way bearing 2 to rotate synchronously clockwise. At this time, the side block 3 outside the one-way bearing 2 rotates synchronously clockwise with the cooling roller 1, and the connecting part 5 is subjected to excessive force and breaks. When the side block 3 rotates to the bottom of the limit swing seat 4, it can push the limit swing seat 4 upward to realize the continued rotation of the cooling roller 1 until the cooling roller 1 stops rotating one after another, and then the machine is shut down for maintenance or replacement.

[0029] Specifically, the limiting groove 61 on the limiting vertical plate 6 is horizontally continuous, allowing the limiting swing seat 4 to pass through. The limiting groove 61 extends in the up and down directions, and the upper and lower ends of the limiting groove 61 are used to effectively limit the swing amplitude of the limiting swing seat 4.

[0030] The swing amplitude of the limiting swing seat 4 is subject to certain restrictions. In the above-mentioned initial position, it can swing upward but cannot swing downward. The top surface of the limiting swing seat 4 can abut against the side block 3 when the cooling roller 1 is reversed to limit the rotation of the cooling roller 1. Therefore, it is ensured that when the one-way bearing 2 is stuck, the structure also has the function of preventing the cooling roller 1 from reversing, and has good safety in use.

[0031] It should be noted that the operation of the cooling roller 1 is not limited to the above-mentioned rotation mode. For example, the cooling roller 1 can rotate counterclockwise as forward rotation and clockwise as reverse rotation, which will not be described in detail here.

[0032] In one possible implementation, see Figures 1 to 5 The limiting swing seat 4 is connected to the limiting vertical plate 6 through a rotating pin 41. The top of the limiting swing seat 4 has a limiting surface 42 that is pressed against the side stopper 3 to limit the position. The bottom of the limiting swing seat 4 has a guide surface 43 that slides with the side stopper 3. The guide surface 43 gradually extends upward on the side close to the one-way bearing 2.

[0033] In this embodiment, a connecting seat 44 is provided on the side of the limiting plate 6 facing away from the cooling roller 1. The limiting swing seat 4 is rotatably connected to the connecting seat 44 of the limiting plate 6 via a rotating pin 41. In its natural state, the limiting swing seat 4 is held in a lower position due to gravity. If the one-way bearing 2 fails and becomes stuck with the cooling roller 1, the side block 3 can push against the bottom surface of the limiting swing seat 4, forcing it to clear the side block 3, ensuring the forward rotation of the cooling roller 1. Simultaneously, the limiting surface 42 on the top of the limiting swing seat 4 limits the side block 3, preventing reverse rotation.

[0034] The setting of the guide surface 43 makes it easier for the side block 3 to push the limiting swing seat 4, thereby causing the side block 3 to rotate around the rotating pin 41, thereby effectively avoiding the side block 3 and meeting the forward rotation requirement of the cooling roller 1 under the action of inertia.

[0035] For some examples, see Figures 1 to 5 The limiting swing seat 4 extends along the axial direction of the cooling roller 1, and the cross section of the limiting swing seat 4 is a right triangle. The limiting swing seat 4 adopts a right triangle structure, wherein the horizontally extending surface corresponding to the right angle side is the limiting surface 42, and the surface corresponding to the hypotenuse is the guide surface 43, which satisfies the limiting function of the side block 3 when the cooling roller 1 is reversed.

[0036] For some examples, see Figures 1 to 5 The bottom of the limiting groove 61 has an inclined surface 62 that abuts against the guide surface 43 for limiting the position. The inclined surface 62 extends gradually upward on the side close to the cooling roller 1. The inclined surface 62 provided at the bottom of the limiting groove 61 can effectively contact the guide surface 43 of the limiting swing seat 4, forming a support and limit for the limiting swing seat 4, so that the limiting swing seat 4 is stably located at a lower position, meeting the anti-reversal function.

[0037] In one possible implementation, see Figures 1 to 5 An elastic member 7 is provided between the rotating pin 41 and the limiting swing seat 4. The elastic member 7 is used to pull the limiting swing seat 4 to be limited to the lower end of the limiting groove 61. The provision of the elastic member 7 can form a unidirectional pulling effect on the lower part of the limiting swing seat 4 away from the cooling roller 1, so that the limiting swing seat 4 is always in a lower position, that is, a position where it can effectively press against the inclined surface 62, thereby avoiding the problem that the free swing of the limiting swing seat 4 affects the anti-reversal effect.

[0038] In one possible implementation, see Figures 1 to 5The connecting member 5 is an annular member that passes through the side block 3 and the limiting swing seat 4. The connecting member 5 is an annular member, and a groove can be correspondingly provided on the surface of the limiting swing seat 4 that contacts the connecting member 5, so that the connecting member 5 can be stuck in the groove to be limited, preventing the connecting member 5 from moving relative to the limiting swing seat 4. The annular member can be made of materials such as iron wire and plastic, and can meet the function of limiting and fixing the outer ring of the one-way bearing 2 under the normal state of the one-way bearing 2. It can also be broken by the large pulling force of the side block 3 when the one-way bearing 2 is stuck, so that the cooling roller 1 can gradually decelerate in the forward direction until it stops, avoiding damage caused by rigid impact.

[0039] In one possible implementation, see Figures 1 to 5 The outer ring of the one-way bearing 2 is provided with a fixed sleeve 21, and the side block 3 is welded to the outer peripheral wall of the fixed sleeve 21. The fixed sleeve 21 on the outer periphery of the one-way bearing 2 is used to install the side block 3 to ensure good connection reliability.

[0040] In one possible implementation, see Figures 1 to 5 The end of the cooling roller 1 is provided with a shaft head 11 for mounting a one-way bearing 2, and a limiting retaining spring 12 is sleeved on the shaft head 11 and located outside the one-way bearing 2. The limiting retaining spring 12 on the shaft head 11 can limit the axial position of the one-way bearing 2, ensuring the reliable installation of the one-way bearing 2.

[0041] In one possible implementation, see Figures 1 to 5 The cooling roller 1 is mounted on the frame 8 via two bearing seats 13. Two bearing seats 13 are provided, and the two bearing seats 13 are mounted one-to-one on the two side walls of the frame 8. The cooling roller 1 is mounted on the frame 8 via the bearing seats 13 at both ends, meeting the support requirements for the cooling roller 1. Furthermore, two limit swing seats 4 can also be symmetrically provided on both sides of the frame 8. At the same time, two one-way bearings 2 can also be provided and connected one-to-one to the two ends of the cooling roller 1, forming an anti-reversal function at both ends of the cooling roller 1.

[0042] In the above-mentioned anti-reversal structure of the cooling roller, the side block 3 outside the one-way bearing 2 is connected to the limit swing seat 4 through the connecting piece 5, so that the cooling roller 1 meets the requirements of one-way operation under the action of the one-way bearing 2. When the one-way bearing 2 fails and becomes stuck, the connecting piece 5 can break under the pulling action of the side block 3, and the cooling roller 1 drives the one-way bearing 2 to rotate clockwise synchronously. The side block 3 can push the limit swing seat 4 upward to realize the continued rotation of the cooling roller 1, and then the machine can be shut down for maintenance or replacement. The above structure meets the anti-reversal effect of the one-way bearing 2 in different states such as normal and stuck, ensures the stability of the equipment operation, facilitates daily inspection and maintenance, ensures product quality, and improves production safety.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
