Description

Technical Field

[0001] This utility model relates to the field of tail rope protection technology, specifically a tail rope protection device for mining hoists. Background Technology

[0002] Mining hoists are key pieces of equipment in mining production, mainly used to lift personnel, materials, and equipment in vertical or inclined shafts. They play an irreplaceable role in mining, transportation, and other processes. The tail rope of a mining hoist is a device used to lift containers up or down.

[0003] Currently, due to its excessive length, the tail rope in actual use can cause swaying during the up-and-down movement of the tail rope and container when the operating speed is too fast. This can lead to repeated contact and even entanglement between adjacent tail ropes, potentially causing damage to both the tail rope and the hoist. Summary of the Invention

[0004] This utility model provides a tail rope protection device for mining hoists. By setting up an adjustment mechanism and a limit wheel to cooperate with each other, it can limit multiple tail ropes of different diameters, reduce the damage caused by the tail ropes touching each other and the problem of shaking and tangling, thereby providing a certain protection effect for the tail ropes.

[0005] To achieve the above objectives, a tail rope protection device for a mining hoist is provided, comprising a mounting base, a fixing plate fixedly connected to one side of the mounting base, two symmetrical fixing plates, mounting grooves formed on the surface of the fixing plates, several mounting grooves arranged side by side, adjustment grooves formed on the bottom surface of the mounting grooves, two symmetrical adjustment grooves, an adjustment plate slidably connected to the inner side of the adjustment groove, a rotating groove formed at the upper end of the adjustment plate, a limit wheel rotatably connected to the inner side of the rotating groove, a rotating column rotatably connected to the inner side of the mounting groove, the outer surface of the rotating column being movably connected to the inner center of the limit wheel, a tail rope body disposed inside the mounting groove, the tail rope body contacting the outer surface of the rotating column, and an adjustment mechanism rotatably connected to the inner side of the fixing plate, the adjustment mechanism being threadedly connected to the inner side of the adjustment plate. By setting up the cooperation between the adjustment mechanism and the limit wheel, multiple tail ropes of different diameters are limited, reducing damage caused by back-and-forth contact and tangling of the tail ropes, thus providing a certain degree of protection for the tail ropes.

[0006] According to the aforementioned tail rope protection device for a mining hoist, the adjusting mechanism includes an adjusting column, a threaded joint, a rotating disc, bolts, and a limiting groove. The adjusting column is rotatably connected to the inner side of a fixed plate, and one end of the adjusting column passes through the middle of the fixed plate and the adjusting plate, extending to the outer side of the other end of the fixed plate. By setting up the mutual cooperation between the adjusting plate and the adjusting column, the adjusting column limits the movement of the adjusting plate, making the movement of the adjusting plate more stable.

[0007] According to the aforementioned tail rope protection device for a mining hoist, the set threads are located on the outer side of the adjusting column. Several sets of set threads are provided, corresponding to the adjusting plates. Two sets of set threads close to each other are symmetrical. The adjusting column is threadedly connected to the adjusting plates via the contact surfaces of the set threads. By rotating the adjusting column, the threads drive the two close-to-each-other adjusting plates to move synchronously towards or away from each other according to the diameter of the tail rope, thereby adjusting the stability of the adjusting plate's position.

[0008] According to the aforementioned tail rope protection device for a mining hoist, the rotating disc is fixedly connected to one end of an adjusting column. Anti-slip stripes are provided on the outer side of the rotating disc, and these stripes are numerous and evenly distributed on the outer side. By providing numerous anti-slip stripes, the friction force when the user rotates the rotating disc is increased, making the rotation more stable.

[0009] According to the aforementioned tail rope protection device for a mining hoist, the surface of the rotating disc has holes, the bolt is disposed inside the holes, and the limiting groove is formed on the side of the fixed plate near the rotating disc. Several limiting grooves are evenly distributed in a ring at equal angles. The end of the bolt away from the hole is threadedly connected to the limiting groove. By setting the mutual cooperation between the bolt and the limiting groove, the rotating disc is limited, preventing the adjusted rotating disc from rotating on its own.

[0010] According to the aforementioned tail rope protection device for a mining hoist, a limiting post is provided on the inner side of the fixed plate. Two limiting posts are provided, symmetrically arranged, and their two ends pass through the fixed plate and the adjusting plate, and are fixedly connected to the side of the adjusting groove that is away from each other. By setting up the mutual cooperation between the limiting posts and the adjusting plate, the adjusting plate is further limited.

[0011] According to the aforementioned tail rope protection device for a mining hoist, the inner side of the adjusting groove and the adjusting plate are fitted together, and the contact surface between the adjusting groove and the adjusting plate is set to a smooth surface. By setting the contact surface between the adjusting plate and the adjusting groove to a smooth surface, the adjusting plate slides more stably inside the adjusting groove.

[0012] According to the aforementioned tail rope protection device for a mining hoist, the limiting wheel engages with the outer side of the rotating column, and the contact surface between the limiting wheel and the rotating column is smooth. By ensuring the limiting wheel engages with the rotating column, the contact is made more complete, resulting in more stable movement of the limiting wheel on the outer side of the rotating column.

[0013] The beneficial effects of this utility model are as follows: by setting up an adjustment mechanism, an adjustment plate and a limit wheel, etc., the structure cooperates with each other to limit multiple tail ropes of different diameters, reduce the damage caused by the tail ropes touching back and forth and the problem of shaking and tangling, and thus play a certain protective effect on the tail ropes.

[0024] The inner side of the fixed plate 2 is provided with limit posts 3. There are two limit posts 3, which are symmetrical to each other. The two ends of the limit posts 3 pass through the fixed plate 2 and the adjusting plate 9 and are fixedly connected to the side of the adjusting groove 5 that is far away from each other. The inner side of the adjusting groove 5 fits with the adjusting plate 9. The contact surface between the adjusting groove 5 and the adjusting plate 9 is set to be smooth. The limit wheel 8 fits with the outer side of the rotating column 6. The contact surface between the limit wheel 8 and the rotating column 6 is set to be smooth.

[0025] The adjustment mechanism 22 includes an adjustment column 2201, a setting thread 2202, a rotating disk 2203, a bolt 2204, and a limiting groove 2205. The adjustment column 2201 is rotatably connected to the inner side of the fixed plate 2. One end of the adjustment column 2201 passes through the middle of the fixed plate 2 and the adjustment plate 9 and extends to the outer side of the other end of the fixed plate 2. The setting thread 2202 is opened on the outer side of the adjustment column 2201. There are several setting threads 2202, which correspond to the adjustment plate 9. Two setting threads 2202 that are close to each other are symmetrical. The adjustment column 2201 is threadedly connected to the contact surface of the adjustment plate 9 through the setting thread 2202.

[0026] The rotating disk 2203 is fixedly connected to one end of the adjusting column 2201. Anti-slip stripes are provided on the outer side of the rotating disk 2203. Several anti-slip stripes are provided and evenly distributed on the outer side of the rotating disk 2203. Holes are provided on the surface of the rotating disk 2203.

After threading, first rotate bolt 2204 and pull bolt 2204 out from the inside of the limiting groove 2205. Next, rotate the rotating disk 2203, causing the rotating disk 2203 to drive the adjusting post 2201 to rotate. When the adjusting post 2201 rotates, it will drive the adjusting plates 9 on both sides of the tail rope body 7 to move closer to each other through the threaded 2202. When the plates 9 approach each other, they will drive the limit wheels 8 to gradually approach the tail rope body 7 until the two limit wheels 8 contact the surface of the tail rope body 7. At this time, the limit wheels 8 will limit the tail rope body 7 one by one, reducing the problem of tail rope body 7 swinging. Then, the two ends of the tail rope body 7 are tied and connected to the hoist and the container respectively. After the connection is completed, the hoisting mechanism is started to allow the tail rope body 7 to slide. At this time, the rotating column 6 and the limit wheels 8 rotate under the contact of the tail rope body 7, which reduces the wear of the tail rope body 7 and increases the service life of the tail rope body 7.
