Description

Technical Field

[0001] This utility model relates to the field of cableway braking technology, and in particular to a manual braking rope device. Background Technology

[0002] A sled is a mechanical device typically used to move heavy objects or suspend sightseeing vehicles for tourists on a cableway. Safety and controllability are paramount during sled operation. Braking systems effectively control the sled's speed. Without braking, a sled moving at high speed could lead to loss of control, causing accidents or equipment damage. Existing braking systems usually require manual braking by the user. When the sightseeing vehicle slides into a station on the cableway, it needs to slow down in advance. However, passengers often cannot accurately slow down in advance to allow the sled to enter the station slowly. If passengers fail to slow down in time, the sled may not be able to enter the station at a safe speed, which is quite dangerous. Utility Model Content

[0003] The purpose of this invention is to provide a manual braking rope device. This device is installed at the front edge of the lower platform and can replace passengers in actively braking, so as to control the speed of the trolley within a suitable range and facilitate entry into the station.

[0004] The purpose of this utility model is to provide a manual braking pull rope device, including a mounting frame and a steel wire rope. Rollers are rotatably connected to both ends of the top of the mounting frame. The bottom end of the roller contacts the steel wire rope. A friction block is provided below the steel wire rope. One end of the friction block is provided with a braking device that can pull the friction block into contact with the steel wire rope. The other end of the friction block is provided with a reset device that can pull the friction block out of contact with the steel wire rope.

[0005] Preferably, the braking device includes a crescent plate, the bottom end of which is rotatably connected to the mounting bracket, a friction block is fixedly connected to the middle of the crescent plate, a first connecting hole is opened at the top of the crescent plate, a tension spring is fixedly installed in the first connecting hole, a second connecting hole is opened at the top of the mounting bracket, and the other end of the tension spring is fixedly installed in the second connecting hole.

[0006] Preferably, the reset device includes a pull plate, the bottom end of which is rotatably mounted in the mounting frame, a friction block fixedly connected to the top of the pull plate, a horizontal plate integrally formed with the pull plate at the bottom end of the pull plate, a control rope fixedly connected to the bottom end of the horizontal plate, a first locking block fixedly connected to the bottom end of the junction between the pull plate and the horizontal plate, a second locking block being fitted to one side of the first locking block, the second locking block being rotatably mounted in the mounting frame, and a handle fixedly connected to the bottom end of the second locking block.

[0010] Preferably, a pulley is rotatably mounted at the bottom of the mounting frame, and the pulley is in contact with the control rope.

[0011] The working principle and usage principle of this utility model are as follows: simply place this device on the front edge of the lower platform, and the braking device will drive the friction block to contact the wire rope, thereby increasing the friction force and preventing the trolley from pushing the device to move, thus achieving braking. To release the braking, simply operate the reset device to make the friction block lose contact with the wire rope, thereby facilitating the sliding of this device.

[0019] To make the technical means, creative features, objectives and effects of the embodiments of this application easier to understand, the embodiments of this application are further described below in conjunction with the figures and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of this application and are not intended to limit the embodiments of this application.

[0020] Figure 1 The diagram schematically illustrates a manual braking pull rope device of this invention, including a mounting frame 1 and a steel wire rope. Rollers 12 are rotatably connected to both ends of the top of the mounting frame 1. The bottom of the rollers 12 contacts the steel wire rope. A friction block 13 is located below the steel wire rope. One end of the friction block 13 is equipped with a braking device 2 capable of pulling the friction block 13 into contact with the steel wire rope, and the other end of the friction block 13 is equipped with a reset device 3 capable of pulling the friction block 13 out of contact with the steel wire rope. The surface of the mounting frame 1 has multiple limiting pin holes 4. By inserting locking pins into the limiting pin holes 4, the rebound amplitude of the braking device 2 can be limited, thereby controlling the contact force between the friction block 13 and the steel wire rope. A buffer pad 5 is fixedly installed at one end of the mounting frame 1. The buffer pad 5 can be made of flexible materials such as rubber to reduce impact force. The fixed shaft of the roller 12 passes through the mounting frame 1, and a locking block 6 is engaged inside the fixed shaft. The locking block 6 can be pulled out, thereby pulling out the fixed shaft of the roller 12 for easy replacement of the roller 12.

[0021] like Figure 2 and Figure 3 The braking device 2 shown includes a crescent plate 21, the bottom end of which is rotatably connected to the mounting bracket 1. A friction block 13 is fixedly connected to the middle of the crescent plate 21. A first connecting hole 22 is opened at the top of the crescent plate 21, and a tension spring 24 is fixedly installed in the first connecting hole 22. A second connecting hole 23 is opened at the top of the mounting bracket 1, and the other end of the tension spring 24 is fixedly installed in the second connecting hole 23.

[0022] In practice, when the equipment is moved to a suitable position on the wire rope, the tension spring 24 will contract, thereby pulling the crescent plate 21 to rotate. The rotation of the crescent plate 21 will drive the friction block 13 to move, so that the friction block 13 comes into contact with the wire rope. When the trolley comes into contact with the mounting frame 1, the friction between the friction block 13 and the wire rope will cause the trolley to decelerate until it stops, thereby preventing the trolley from entering the station at too high a speed.

[0023] like Figure 2 and Figure 4 The reset device 3 shown includes a pull plate 31, the bottom end of which is rotatably mounted in the mounting frame 1. A friction block 13 is fixedly connected to the top of the pull plate 31. A horizontal plate 32 integrally formed with the pull plate 31 is provided at the bottom end of the pull plate 31. A control rope 33 is fixedly connected to the bottom end of the horizontal plate 32. A first locking block 34 is fixedly connected to the bottom end of the junction between the pull plate 31 and the horizontal plate 32. A second locking block 35 is connected to one side of the first locking block 34. The second locking block 35 is rotatably mounted in the mounting frame 1. A handle 36 is fixedly connected to the bottom end of the second locking block 35. A pulley 7 is rotatably mounted at the bottom end of the mounting frame 1. The pulley 7 is in contact with the control rope 33. The rotatable nature of the pulley 7 makes it convenient for the user to pull the control rope 33.

[0024] In practice, when the braking device 2 needs to be reset to release the braking state, simply hold the control rope 33 and pull it downwards. The control rope 33 will pull the horizontal plate 32 to move, and the movement of the horizontal plate 32 will cause the pulling plate 31 to rotate. The rotation of the pulling plate 31 will cause the friction block 13 to move, thereby causing the friction block 13 to lose contact with the wire rope, thus facilitating the movement of the mounting frame 1. The rotation of the pulling plate 31 will also cause the first locking block 34 and the second locking block 35 to engage and connect. The second locking block 35 can limit the rebound of the first locking block 34, so that the friction block 13 can always lose contact with the wire rope. When you want the friction block 13 to re-engage with the wire rope, simply turn the handle 36. The rotation of the handle 36 will cause the second locking block 35 to lose engagement with the first locking block 34, thereby allowing the pulling plate 31 to reset, and thus causing the friction block 13 to re-engage with the wire rope.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
