Technical Field

[0001] This utility model relates to the technical field of high-safety wire rope brakes, and in particular to a high-safety wire rope brake. Background Technology

[0002] A wire rope brake is a mechanical device used to control, decelerate, or stop the movement of a wire rope. It is widely used in systems involving wire rope transmission, such as cranes, elevators, cableways, and mining equipment. Its core function is to ensure load safety and prevent the wire rope from slipping uncontrollably or breaking.

[0003] Existing wire rope brakes can be used for emergency braking of wire ropes and have high safety. However, these brakes contain hydraulic cylinders that control the clamping and fastening components. The hydraulic cylinder's compression column lacks a dustproof component, causing it to accumulate dust. Some of this dust is carried to the inner wall of the hydraulic cylinder, leading to wear on the components and potential malfunctions. Therefore, we provide a wire rope brake with higher safety.

[0023] Example 1

[0024] like Figures 1-6 As shown, this utility model provides a technical solution: a high-safety wire rope brake, comprising: a brake body 1, a dustproof mechanism 2 provided on the inner side of the brake body 1, the dustproof mechanism 2 including a cover 21, a first mounting groove 22 and a second mounting groove 23 provided inside the cover 21, a magnet 24 sleeved inside the cover 21, the magnet 24 being fixedly connected to the cover 21, and a mounting ring 25 provided inside the first mounting groove 22 and the second mounting groove 23, a wear-resistant rubber pad 26 sleeved inside the mounting ring 25. The wear-resistant rubber pad 26 is fixedly connected to the mounting ring 25. A sealing gasket 27 is fitted inside the cover 21. The sealing gasket 27 is slidably connected to the cover 21. A sealing groove 28 that fits the sealing gasket 27 is provided on the cover 21. A fixing mechanism 3 is provided on the outside of the cover 21. The fixing mechanism 3 includes a connecting block 31. A fixing block 29 is fixedly connected to the outer surface of the cover 21. A positioning block 201 is fixedly connected to the outer surface of the cover 21. The positioning block 201 is fitted inside the fixing block 29. The positioning block 201 is slidably connected to the fixing block 29.

[0025] In this embodiment, two covers 21 are provided to provide dust protection for the extrusion column of the hydraulic cylinder. The inner side of the cover 21 is provided with a first mounting groove 22 and a second mounting groove 23, and both mounting grooves 22 and 23 can accommodate the mounting ring 25 and the wear-resistant rubber pad 26. Thus, the mounting ring 25 and the wear-resistant rubber pad 26 can be installed in different forms and work together to effectively scrape off the dust on the outer surface of the extrusion column during telescopic movement, preventing dust from entering the interior of the hydraulic cylinder. At the same time, a magnet 24 is provided, which can attract and fix the mounting ring 25, so that the mounting ring 25 can be installed in different forms into the interior of the first mounting groove 22 and the second mounting groove 23 on one of the covers 21, thereby making the installation of the other cover 21 more convenient.

[0026] Example 2

[0027] like Figures 1-6 As shown, the connecting block 31 is fixedly connected to the cover 21. An insert block 32 is sleeved inside the connecting block 31. The insert block 32 is slidably connected to the connecting block 31. The insert block 32 is fixedly connected to the cover 21. A locking rod 33 is sleeved inside the connecting block 31 and the insert block 32. The locking rod 33 is slidably connected to both the connecting block 31 and the insert block 32. A limiting ring 34 is sleeved on the outer surface of the locking rod 33. The limiting ring 34 is fixedly connected to the locking rod 33. A spring 35 is sleeved on the outer surface of the locking rod 33. The two ends of the spring 35 are fixedly connected to the outer surface of the limiting ring 34 and the inner wall of the connecting block 31, respectively. A pull block 36 is fixedly connected to one end of the locking rod 33.

[0028] In this embodiment, a fixing mechanism 3 is provided, which can be used in conjunction with the dustproof mechanism 2 to ensure the stability of the dustproof mechanism 2 during use. A locking rod 33 is provided, which can be engaged into the interior of the insert block 32, so that the insert block 32 will not detach after entering the interior of the connecting block 31. Thus, the two covers 21 can maintain a stable state after being fitted together.

[0029] Working principle:

[0030] like Figures 1-6As shown, in use, one of the covers 21 in the dustproof mechanism 2 can be placed on the outside of the extrusion column of the hydraulic cylinder of the wire rope brake. Then, different mounting rings 25 and wear-resistant rubber pads 26 are installed into mounting groove one 22 and mounting groove two 23, ensuring that the mounting rings 25 and wear-resistant rubber pads 26 in the mounting groove one 22 and mounting groove two 23 are in a cooperative state, guaranteeing that dust on the extrusion column can be effectively scraped off. Afterwards, a portion of the mounting rings 25 are installed into mounting groove one 22 and mounting groove two 23. Inside the slot 23, the mounting ring 25 is attracted by the magnet 24, thus maintaining a relatively stable state. Then, the cover 21 moves part of the mounting ring 25 to contact the extrusion column of the hydraulic cylinder. Next, the remaining mounting ring 25 and the wear-resistant rubber pad 26 are installed, ensuring the wear-resistant rubber pad 26 contacts the outer surface of the extrusion column. Then, two sealing gaskets 27 are installed into the sealing groove 28 on one of the cover 21. Finally, the pull block 36 is pulled, using the pull block 36 to drive the locking rod 33. Sliding is performed, and the lever 33 can compress the spring 35 using the limiting ring 34, so that the spring 35 can generate elastic force. Then, another cover 21 is installed. When the cover 21 is installed, the remaining mounting ring 25 can enter the mounting groove 22 and mounting groove 23 opened on the cover 21, and the other half of the sealing gasket 27 can enter the sealing groove 28 opened on the cover 21. At the same time, part of the insert block 32 can enter the interior of the connecting block 31. When the two covers 21 are tightly fitted, it can... When the pull block 36 is released, the elastic force of the spring 35 is released instantly, and the locking rod 33 is reset, so that the locking rod 33 can be tightly locked into the interior of the insert block 32. Thus, with the cooperation of the fixing mechanism 3, the entire dustproof mechanism 2 can remain stable. Even if the hydraulic cylinder's pressing rod is used for extension and retraction and gets contaminated with some dust, the wear-resistant rubber pad 26 can be used to scrape off the dust on its outer surface when the pressing rod is reset. Thus, the dust will not enter the interior of the hydraulic cylinder, ensuring the safety of the wire rope brake.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
