Description

Technical Field

[0001] This utility model belongs to the technical field of mine hoisting machines, specifically relating to a multi-stage isolation device for mine tail ropes. Background Technology

[0002] Multi-rope friction hoists are widely used in coal mines and metal mines, and are important transportation equipment for personnel and materials in shaft mining.

[0003] In multi-rope friction hoists, the tail rope is indispensable. Due to the depth of the mine, the required tail rope is quite long. However, a long tail rope can easily cause it to swing during hoist operation, resulting in adjacent tail ropes rubbing against each other. In severe cases, it can even cause two tail ropes to become entangled. Therefore, a multi-stage tail rope isolation device is needed to separate the multiple strands of tail rope. However, when using a traditional steel beam type tail rope isolation device, if the tail rope swings and accidentally collides with the steel structure on the steel beam type tail rope isolation device, the tail rope will rub against the steel structure, which will cause a certain degree of wear on the tail rope and thus affect its service life.

[0004] Therefore, this utility model provides a multi-stage isolation device for mine tail ropes to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-stage isolation device for mine tail ropes, which aims to solve the problem that when the tail rope swings and accidentally collides with the steel structure on the steel beam tail rope isolation device in the existing technology, the tail rope will rub against the steel structure, which will cause a certain degree of wear on the tail rope.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage isolation device for mine tail ropes, including a mounting frame. A positioning groove is formed on the top surface of the mounting frame, a positioning block is connected to the inner surface of the positioning groove, a connecting block is connected to the top surface of the positioning block, an isolation plate is provided at one end of the connecting block, first stop blocks are connected to both sides of the isolation plate, a second stop block is connected to the end of the mounting frame facing the isolation plate, a groove is formed on one end of the surface of the second stop block, one end of a third bolt is connected to the inner surface of the groove, and a tail rope is provided on one side of the isolation plate.

[0007] In order to facilitate the assembly and disassembly of the connecting block, as a preferred embodiment of the multi-stage isolation device for mine tail ropes of this utility model, a first bolt is connected through the surface of the mounting frame away from the isolation plate. One end of the first bolt passes through a limiting hole opened on one end surface of the positioning block, and the first bolt forms a threaded connection with the mounting frame through the limiting hole.

[0008] In order to facilitate the assembly and disassembly of the second stop, as a preferred embodiment of the multi-stage isolation device for mine tail ropes of this utility model, the other end of the third bolt passes through the second stop and the mounting frame to form a threaded connection.

[0009] In order to realize the movement of the sliding block, as a preferred embodiment of the multi-stage isolation device for mine tail rope of this utility model, the connecting block has a movable groove on one end surface facing the isolation plate, a sliding rod is connected to the inner surface of the movable groove, one end of the sliding rod passes through the sliding block, and one end of the sliding block extends into the placement groove, which is opened on the bottom surface at both ends of the isolation plate.

[0010] In order to buffer the sliding block, as a preferred embodiment of the multi-stage isolation device for mine tail rope of this utility model, springs are provided on both sides of the sliding block and penetrated by sliding rods. One end surface of the spring is connected to the inner surface of the movable groove, and the other end surface of the spring is connected to the sliding block.

[0011] In order to facilitate the assembly and disassembly of the isolation plate, as a preferred embodiment of the multi-stage isolation device for mine tail ropes of this utility model, a second bolt is connected through the top surface of the isolation plate, and the other end of the second bolt forms a threaded connection with the sliding block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes the cooperation of a mounting frame, an isolation plate, a first stop, and a second stop to separate the multiple strands of the tail rope in a multi-rope friction hoist, thereby achieving multi-stage isolation of the tail rope. Simultaneously, the first stop and the second stop are respectively installed on the isolation plate and the mounting frame. This protects the tail rope from direct impact with the mounting frame and the isolation plate, reducing wear and tear and extending its service life.

[0014] This invention utilizes the cooperation of a sliding block, a sliding rod, a spring, and a second bolt. When the isolation plate is impacted by the tail rope, the isolation plate will cause the sliding block to slide on the sliding rod, thereby compressing the spring. In this way, the spring will reduce the impact force on the isolation plate during the compression and extension movement, thus improving the service life of the first stop block on the isolation plate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 The present invention provides the following technical solution: a multi-stage isolation device for mine tail rope, including a mounting frame 1, a positioning groove 2 on the top surface of the mounting frame 1, a positioning block 3 connected to the inner surface of the positioning groove 2, a connecting block 4 connected to the top surface of the positioning block 3, an isolation plate 12 at one end of the connecting block 4, first blocks 14 connected to both sides of the isolation plate 12, a second block 15 connected to the end of the mounting frame 1 facing the isolation plate 12, a groove 16 on one end of the second block 15, a third bolt 17 connected to the inner surface of the groove 16, and a tail rope 18 on one side of the isolation plate 12.

[0023] Preferably, a first bolt 5 is connected to the end surface of the mounting bracket 1 away from the isolation plate 12. One end of the first bolt 5 passes through the limiting hole 6 opened on one end surface of the positioning block 3, and the first bolt 5 forms a threaded connection with the mounting bracket 1 through the limiting hole 6.

[0024] In practical use, the positioning block 3 on the connecting block 4 is slidably inserted into the positioning groove 2, and the first bolt 5 is screwed into the mounting bracket 1 through the limiting hole 6 on the positioning block 3. This fixes the position of the connecting block 4 in the mounting bracket 1. By unscrewing the first bolt 5, the positioning block 3 can be separated from the positioning groove 2, and the connecting block 4 can be disassembled.

[0025] Preferably, the other end of the third bolt 17 passes through the second stop 15 and forms a threaded connection with the mounting bracket 1.

[0026] In practical use, the third bolt 17 is inserted through the second stop 15 and screwed into the mounting bracket 1 to fix the second stop 15 on the mounting bracket 1. At this time, the head of the third bolt 17 will be in the groove 16 on the second stop 15, so that the head of the third bolt 17 will not have a protruding part on the second stop 15.

[0027] Preferably, the connecting block 4 has a movable groove 7 on one end surface facing the isolation plate 12, and a sliding rod 8 is connected to the inner surface of the movable groove 7. One end of the sliding rod 8 passes through the sliding block 9, and one end of the sliding block 9 extends into the placement groove 11. The placement groove 11 is opened on the bottom surface at both ends of the isolation plate 12.

[0028] In actual use, one end of the sliding block 9 on the connecting block 4 will slide into the placement groove 11 opened at the bottom of the isolation plate 12, so that the sliding block 9 is connected with the isolation plate 12. In this way, the isolation plate 12 will slide on the slide rod 8 with the sliding block 9, so that the sliding block 9 will also slide in the movable groove 7 on the connecting block 4.

[0029] Preferably, springs 10 are provided on both sides of the sliding block 9 and are penetrated by the sliding rod 8. One end surface of the spring 10 is connected to the inner surface of the movable groove 7, and the other end surface of the spring 10 is connected to the sliding block 9.

[0030] In practical use, when the sliding block 9 slides on the slide rod 8, the sliding block 9 will compress the spring 10 on the slide rod 8, allowing the sliding block 9 to move elastically through the spring 10.

[0031] Preferably, a second bolt 13 is connected through the top surface of the isolation plate 12, and the other end of the second bolt 13 is threadedly connected to the sliding block 9.

[0032] In practical use, when the isolation plate 12 is placed, one end of the sliding block 9 will slide into the placement groove 11 opened at the bottom of the isolation plate 12. At this time, the second bolt 13 is screwed through the isolation plate 12 into the sliding block 9, so that the isolation plate 12 and the sliding block 9 can be connected together. When the second bolt 13 is unscrewed, the isolation plate 12 can be separated from the sliding block 9, so that the operator can maintain and replace the isolation plate 12.

[0033] It should be noted that the first stop 14 and the second stop 15 are made of polyurethane. Polyurethane has good sliding properties and wear resistance. When the tail rope 18 comes into contact with the first stop 14 and the second stop 15, the contact point of the tail rope 18 can be protected, thereby reducing wear on the tail rope 18.

[0034] Working principle: When using this mine tail rope multi-stage isolation device, first install the mounting frame 1 at the designated position around the mine tail rope 18. Then, slide the positioning blocks 3 on the connecting block 4 into the positioning grooves 2. Tighten the first bolt 5 through the limiting hole 6 on the positioning block 3 into the mounting frame 1 to fix the position of the connecting block 4 on the mounting frame 1. Then, place the isolation plate 12, allowing one end of the sliding block 9 on the connecting block 4 to slide into the placement groove 11 at the bottom of the isolation plate 12. Then, use the first bolt 5... Two bolts 13 are screwed through the isolation plate 12 and into the sliding block 9, thus connecting the isolation plate 12 and the sliding block 9 together. At this point, the isolation plate 12 is installed on the mounting frame 1. By installing multiple isolation plates 12, the tail rope 18 of the multi-rope friction hoist used in the mine can be separated, thereby achieving multi-stage isolation of the tail rope 18 of the multi-rope friction hoist. When the tail rope 18 accidentally collides with the mounting frame 1 or the isolation plate 12, the mounting frame 1 and the isolation plate 1... The second stop 15 and the first stop 14 on plate 2 will separate the tail rope 18, preventing the tail rope 18 from directly colliding with the mounting frame 1 and the isolation plate 12, thereby protecting the tail rope 18, reducing the wear of the tail rope 18 when it collides, and improving the service life of the tail rope 18. When the second stop 15 and the first stop 14 are damaged and need to be replaced, simply separate the second bolt 13 and the third bolt 17 to remove the isolation plate 12 and the second stop 15, allowing the operator to replace them with new isolation plates 12 and the second stop 15, ensuring the effectiveness of the first stop 14 on the isolation plate 12 and the second stop 15 on the mounting frame 1. Furthermore, when the tail rope 18 collides with the isolation plate 12, the isolation plate 12 will cause the sliding block 9 to slide on the sliding rod 8 due to the collision. At this time, the sliding block 9 will squeeze the spring 10 while sliding. In this way, the spring 10 will weaken the impact force on the isolation plate 12 during the compression and extension movement, thereby improving the service life of the first stop 14 on the isolation plate 12.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
