Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical industry equipment, in particular to a movable rack that can be quickly replaced. Background Art

[0002] A walking cooling bed is a common piece of equipment used in rolling mills within metallurgical enterprises. It's located behind a sawing machine or shearing machine and is used to transport rolled steel horizontally. When the cooling bed is operating, the moving rack moves in a step-by-step manner, transporting the steel to the stationary rack. During this motion, the teeth near the loading end of the moving rack constantly rub against the incoming material, causing the first tooth near the loading end to wear rapidly. When the wear exceeds a certain limit, the first tooth loses its grip on the incoming material, preventing the steel from being transported. At this point, the machine must be shut down and the moving rack replaced. Because the moving rack is mounted on a movable bracket via a pin, replacement is cumbersome. Furthermore, the moving rack is relatively long, and replacing the entire moving rack due to wear on the first tooth is a significant waste. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] It should be noted that, in the description of the present invention, the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0028] In addition, it should be understood that for the convenience of description, the sizes of the various components shown in the drawings are not drawn according to the actual scale.

[0029] It should be noted that like numbers and letters represent similar items in the following figures, so once an item is defined or described in one figure, it will not need to be further discussed and described in detail in the description of the subsequent figures.

[0030] Before understanding the present invention, it is necessary to understand that Figure 1 As shown, the walking cooling bed includes a static beam mechanism 1, a dynamic beam mechanism 2 and a driving device 3. The static beam mechanism 1 includes a static rack 11 and a static gear bracket 12 fixed to the ground. The dynamic beam mechanism 2 includes a dynamic rack 21 and a dynamic gear movable bracket 22 installed between the dynamic rack 21 and the driving device 3. The driving device 3 can drive the dynamic gear movable bracket 22 to realize the stepping motion of the dynamic rack 21. When the dynamic beam mechanism 2 moves, the tooth profiles of the dynamic rack 21 and the static rack 11 are staggered and cooperate with each other. The dynamic beam mechanism 2 of the walking cooling bed adopts a cyclic step-by-step movement of lifting-lateral movement-falling-backward-and-lifting to realize the flipping of the steel on the walking cooling bed.

[0031] like Figures 1 to 8 As shown, the present invention provides a technical solution: a quickly replaceable movable rack, wherein the movable rack 21 includes a rack body 7, a first tooth portion 5, and a second tooth portion 4. The first tooth portion 5 is detachably mounted on the rack body 7, and the first tooth portion 5 is mounted near the loading end where the steel is stored. The second tooth portion 4 is fixed to the rack body 7. Along the stepping motion direction of the movable rack 21, the first tooth portion 5 and the second tooth portion 4 are smoothly connected and mutually adapted. In an embodiment of the present invention, the rack body 7 and the second tooth portion 4 are integrally connected, and the tooth profile size and tooth profile angle of the first tooth portion 5 and the second tooth portion 4 are the same, so as to better achieve the turning of the steel on the walking cooling bed.

[0032] Specifically, in the embodiment of the present invention, the first tooth portion 5 includes a slot plate 51 and an insert plate 52. Along the stepping motion direction of the movable rack 21, the slot plate 51 is fixedly attached to the rack body 7. A slot is formed on the slot plate 51, or the slot plate 51 can cooperate with the rack body 7 to form a slot. Furthermore, after being fixed, the top surface of the slot plate 51 is lower than the tooth groove of the first tooth portion 5. The insert plate 52 is formed with the tooth profile of the first tooth portion 5, and can be assembled into the slot. When the insert plate 52 is assembled into the slot, a gap of 1 to 5 mm (e.g., 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, or 5 mm) is left to facilitate installation or removal of the insert plate 52.

[0033] Furthermore, the slot plate 51 includes a slot plate body 51A and a baffle 51B. The baffle 51B is fixed to the slot plate body 51A. The slot plate body 51A has screw holes through which screws are inserted to tighten the insert plate 52. When the teeth on the first tooth portion 5 become worn and need to be replaced, the machine is stopped, the screws 6 are loosened, and the insert plate 52 is pulled out and replaced, allowing the walking-beam cooling bed to continue in use. Not only is replacement convenient, but only the easily worn insert plate 52 needs to be replaced, eliminating the need to replace the entire movable rack 21, thus reducing costs.

[0034] like Figures 3 and 4 The figure shows a first embodiment of the slot plate 51 of the present invention, in which a baffle 51B cooperates with the slot plate body 51A to form a slot into which the inserting plate 52 can be assembled. The top surface of the baffle 51B can be used to support the inserting plate 52 after assembly. In this embodiment, the baffle 51B can be an L-shaped steel plate with an inner side. The sides of the two L-shaped steel plates are welded to a side surface of the slot plate body 51A, and the bottom surfaces of the two L-shaped steel plates are welded to the rack body 7. In other embodiments, a single channel steel can be used as the baffle 51B, with the sides of the channel steel welded to a side surface of the slot plate body 51A and the bottom surface of the channel steel welded to the rack body 7.

[0035] like Figures 5 and 6The figure shows a second embodiment of the slot plate 51 of the present invention, wherein the slot plate 51 includes a slot plate body 51A and two baffles 51B disposed on either side of the slot plate body 51A. The two baffles 51B are located between the rack body 7 and the slot plate body 51A. The two sides of the two baffles 51B are welded to the rack body 7 and the slot plate body 51A, respectively. The slot plate body 51A can cooperate with the rack body 7 through the two baffles 51B to form a slot, into which the insert plate 52 can be assembled. The top surface of the baffles 51B can be used to support the assembled insert plate 52. After welding, the welds are then painted or treated with other protective methods. Specifically, baffles 51B are welded to both sides of the slot plate 51. The side of the baffle 51B away from the slot plate 51 is welded to the rack body 7. The baffles 51B on both sides can prevent the insert plate 52 from being overturned and tilted by the loaded steel during loading, thereby affecting the transportation of the steel.

[0036] In the embodiment of the present invention, the number of teeth of the first tooth portion 5 provided on the inserting plate 52 is 2 to 5. In order to facilitate the installation and fixation of the inserting plate 52 and reduce the cost, preferably, the number of teeth of the first tooth portion 5 is 3.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
