Description

Technical Field

[0001] This application relates to the field of winch protection technology, and in particular to a winch protection device for a heating furnace. Background Technology

[0002] The repair process of rolls mainly includes turning and cleaning the roll surface, heat strengthening, welding repair, and cooling. During the heat strengthening process, the roll needs to be placed in a heating furnace for heating to increase its hardness. The sealing door of the heating furnace is raised and lowered using a winch and pulley assembly.

[0003] The exposed nature of the winch makes it susceptible to dust and debris accumulation, hindering cleaning and interfering with its normal operation. Current technology typically involves installing a protective cover around the winch to protect it and reduce the impact of dust and debris. However, existing covers are bolted to the base plate where the winch is mounted, making the removal of the cover for maintenance cumbersome and reducing maintenance efficiency.

[0004] Regarding the aforementioned technologies, the inventors believe that existing winch guards have a cumbersome disassembly and assembly process, which reduces the maintenance efficiency of winches. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a winch protection device for a heating furnace.

[0006] The winch protection device for a heating furnace provided in this application adopts the following technical solution:

[0007] A winch protection device for a heating furnace includes a base plate, a winch mounted on the base plate, a mounting mechanism mounted on the base plate, and a protective mechanism. The mounting mechanism includes a mounting frame and a connecting plate located on the side of the mounting frame near the base plate. The mounting frame is located outside the winch. The connecting plate is connected to the base plate by bolts. The protective mechanism includes a protective cover for covering the outside of the winch, a snap-fit ​​block on the protective cover, and a snap-fit ​​groove on the mounting frame. The snap-fit ​​block snaps into the snap-fit ​​groove, and the side of the protective cover away from the snap-fit ​​block is hinged to the mounting frame.

[0008] By adopting the above technical solution, the protective cover is installed on the mounting frame. When maintenance of the winch is required, the protective cover can be opened by rotating it, allowing for maintenance. When it is necessary to close the protective cover, the locking block is aligned with the locking slot to close the cover, thus protecting the winch. The opening and closing process of the protective cover is simple and convenient, facilitating winch maintenance and improving maintenance efficiency.

[0009] Preferably, the protective cover has a handle on the side near the snap-fit ​​block.

[0010] By adopting the above technical solution, staff can easily open and close the protective cover, further improving the maintenance efficiency of the winch.

[0011] Preferably, the mounting frame is provided with a limiting component for limiting the locking block. The limiting component includes a mounting groove formed on the mounting frame, a limiting spring disposed in the mounting groove, a limiting block, and a pull rod. The mounting groove communicates with the locking groove. One end of the limiting spring is connected to the limiting block, and the other end is connected to the mounting frame. The limiting spring is used to push the limiting block out of the mounting groove. A connecting hole is connected to the side of the mounting groove away from the locking groove. One end of the pull rod is connected to the locking block, and the other end extends out of the connecting hole. A limiting groove is formed on the locking block, and the limiting block engages with the limiting groove.

[0012] By adopting the above technical solution, pulling the lever causes the limiting block to retract into the mounting groove, then pushing the snap-fit ​​block into the snap-fit ​​groove, releasing the lever, and the limiting spring pushes the limiting block into the limiting groove, thereby limiting the snap-fit ​​block and the protective cover, improving the connection stability between the protective cover and the mounting frame. When it is necessary to open the protective cover, pulling the lever away from the limiting groove will open the protective cover.

[0013] Preferably, a limit rod is connected to one end of the pull rod that extends out of the connecting hole.

[0014] By adopting the above technical solution, the limiting rod limits the position of the pull rod, thereby improving the limiting stability of the limiting component on the locking block.

[0015] Preferably, the end of the limiting block away from the limiting spring is provided with a first guide slope, and the end of the snap-fit ​​block away from the protective cover is provided with a second guide slope, with the first guide slope and the second guide slope being arranged parallel to each other.

[0016] By adopting the above technical solution, when the protective cover needs to be closed, the locking block is pushed to move closer to the locking groove. The locking block abuts against the first guide slope through the second guide slope. During the process of the locking block being inserted into the locking groove, it simultaneously pushes the limiting block back into the mounting groove. When the limiting groove is aligned with the mounting groove, the limiting spring pushes the limiting block into the limiting groove, thereby achieving the limiting of the protective cover, further improving the efficiency of the protective cover closing process, and thus improving the maintenance efficiency of the winch.

[0017] Preferably, the protective cover has an observation window at the top.

[0018] By adopting the above technical solution, the observation window allows staff to observe the working status of the winch without opening the protective cover, thereby determining whether the winch needs maintenance. This eliminates the need to open the protective cover and further improves the working efficiency of the winch.

[0019] Preferably, a first sealing gasket is provided at the bottom of the protective cover, and a second sealing gasket is provided on the side of the mounting frame away from the base plate. When the snap-fit ​​block snaps into the snap-fit ​​groove, the first sealing gasket abuts against the second sealing gasket.

[0020] By adopting the above technical solution, the setting of the first sealing gasket and the second sealing gasket improves the protective effect of the protective cover on the winch and reduces the situation where dust and impurities enter the interior of the protective cover from the gap between the protective cover and the mounting frame.

[0021] Preferably, the base plate has a through hole through which the wire rope of the winch passes, and a cleaning brush for cleaning the wire rope is provided in the through hole.

[0022] By adopting the above technical solution, the cleaning brush cleans the wire rope of the winch, thereby reducing the situation where the wire rope carries dust and impurities into the protective cover, and thus improving the operational stability of the winch.

[0023] In summary, this application has the following beneficial technical effects:

[0024] 1. The operation of opening and closing the protective cover is simple and convenient, thereby improving the maintenance efficiency of the winch;

[0025] 2. By limiting the locking block with the limiting component, the connection stability between the protective cover and the mounting frame is improved, thereby improving the protective effect of the protective cover on the winch. Attached Figure Description

The mounting mechanism 3 includes a mounting frame 31 and a connecting plate 32 fixedly mounted on the side of the mounting frame 31 near the base plate 1. The mounting frame 31 is located outside the winch 2, and the connecting plate 32 is connected to the base plate 1 by bolts. The protective mechanism 4 includes a protective cover 41 for covering the outside of the winch 2, a snap-fit ​​block 42 fixedly mounted on the protective cover 41, and a snap-fit ​​groove 43 formed on the mounting frame 31. The snap-fit ​​block 42 snaps into the snap-fit ​​groove 43, and the side of the protective cover 41 away from the snap-fit ​​block 42 is hinged to the mounting frame 31. A limiting component 44 is provided on the mounting frame 31 to limit the movement of the snap-fit ​​block 42.

[0033] A handle 46 is fixedly installed on the side of the protective cover 41 near the snap-fit ​​block 42. An observation window 47 is fixedly installed on the top of the protective cover 41.

[0034] A through hole 11 is provided on the base plate 1. The wire rope 21 of the winch 2 passes through the through hole 11. A cleaning brush 12 for cleaning the wire rope 21 is fixedly installed in the through hole 11.

[0035] The limiting component 44 includes a mounting groove 441 formed on the mounting frame 31, a limiting spring 442 disposed in the mounting groove 441, a limiting block 443, and a pull rod 444. The mounting groove 441 communicates with the snap-fit ​​groove 43. One end of the limiting spring 442 is fixedly connected to the limiting block 443, and the other end is fixedly connected to the mounting frame 31. The limiting spring 442 is used to push the limiting block 443 out of the mounting groove 441. A connecting hole 445 is connected to the side of the mounting groove 441 away from the snap-fit ​​groove 43. One end of the pull rod 444 is fixedly connected to the snap-fit ​​block 42, and the other end extends out of the connecting hole 445. A limiting rod 446 is fixedly connected to the end of the pull rod 444 that extends out of the connecting hole 445. A limiting groove 421 is formed on the snap-fit ​​block 42, and the limiting block 443 snaps into the limiting groove 421.

[0036] The end of the limiting block 443 away from the limiting spring 442 is provided with a first guide slope 447, and the end of the snap-fit ​​block 42 away from the protective cover 41 is provided with a second guide slope 422.

[0037] The bottom of the protective cover 41 is fixedly provided with a first sealing gasket 48, and the side of the mounting frame 31 away from the base plate 1 is fixedly provided with a second sealing gasket 33. When the snap-fit ​​block 42 snaps into the snap-fit ​​groove 43, the first sealing gasket 48 and the second sealing gasket 33 abut against each other.

[0038] The implementation principle of the protective device for the winch 2 of a heating furnace according to an embodiment of this application is as follows: When the winch 2 needs to be repaired, by pulling the limiting rod 446, the pull rod 444 and the limiting block 443 move away from the limiting groove 421, thereby separating the limiting block 443 from the limiting groove 421. Then, by using the handle 46 to drive the protective cover 41 to rotate away from the mounting frame 31, the protective cover 41 can be opened, thus facilitating the repair and maintenance of the winch 2. After the repair is completed, by using the handle 46 to drive the protective cover 41 to rotate closer to the mounting frame 31, the locking block 42 abuts against the second guide slope 422 and the first guide slope 447, thereby causing the locking block 42 to insert into the locking groove 43 and simultaneously pushing the limiting block 443 back into the mounting groove 441. When the limiting block 443 is aligned with the limiting groove 421, the limiting spring 442 pushes the limiting block 443 into the limiting groove 421, thereby making the protective cover 41 stably connected to the mounting frame 31. The opening and closing process of the protective cover 41 is simple and convenient, thereby improving the maintenance effect of the winch 2.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
