Description
Technical Field
[0001] This utility model relates to the field of hydraulic winches, and in particular to a hydraulic winch for core sampling in mining exploration. Background Technology
[0002] In the field of mineral exploration, hydraulic winches for coring are one of the core pieces of equipment. They are mainly used to control the raising and lowering of exploration ropes and work with coring devices to collect underground rock samples. Relying on the stable performance of hydraulic drive, they can adapt to the complex spatial environment and load requirements of underground mines, providing key support for the efficient advancement of exploration operations. They are widely used in exploration projects for various mineral resources, including metallic and non-metallic minerals.
[0003] Traditional hydraulic winches for core drilling in mining operations have significant technical limitations in practical use. Because the exploration ropes need to penetrate deep underground and come into direct contact with rock formations and mud, a large amount of mud easily adheres to the rope surface during winding. This adhered mud contaminates the main components of the winch during rope winding, accelerating wear on the rope and winch, shortening the equipment's lifespan. Furthermore, the hardened lumps formed after the mud dries can cause rope jamming, affecting the continuity and safety of exploration operations. Utility Model Content

The winch body is fixedly installed on the upper end of the winch base. A support frame is fixedly installed on the front end of the winch base. The support frame consists of a square rod and a connecting frame. Two connecting frames are symmetrically fixedly installed at both ends of the square rod. A mounting slide is slidably installed on the square rod. The mounting slide consists of a circular tube, a support slide, and an inner ring. The circular tube is fixedly installed on the upper end of the support slide. The inner ring is fixedly installed on the inner wall of the circular tube.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0015] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, a hydraulic winch for core sampling in mining includes a winch base 1 and a winch body 7. The winch body 7 is fixedly installed on the upper end of the winch base 1. A support frame 2 is fixedly installed on the front end of the winch base 1. The support frame 2 consists of a square rod 8 and a connecting frame 9. There are two connecting frames 9, which are symmetrically fixedly installed at both ends of the square rod 8. A mounting slide 3 is slidably installed on the square rod 8. The mounting slide 3 consists of a circular tube 13, a support slide 14, and an inner ring 17. The circular tube 13 is fixedly installed on the upper end of the support slide 14, and the inner ring 17 is fixedly installed on the inner wall of the circular tube 13. A water spray assembly 4 is fixedly installed on the circular tube 13. The water spray assembly 4 consists of a main pipe 19, an annular pipe 20, and a spray nozzle. The system consists of a head 21, two annular tubes 20 symmetrically fixedly installed on the main pipe 19, several nozzles 21 installed on the two annular tubes 20 respectively, and a brushing assembly 5 installed on the circular pipe 13. The brushing assembly 5 consists of a rotating ring 22, a limiting ring 23, a toothed ring 24, bristles 25, a servo motor 26, and a gear 27. The limiting ring 23 is fixedly sleeved on the rotating ring 22, the toothed ring 24 is fixedly installed on the front end of the rotating ring 22, the bristles 25 are fixedly installed on the inner wall of the rotating ring 22, and the gear 27 is fixedly installed on the output shaft of the servo motor 26, meshing with the toothed ring 24. A guide frame 6 is fixedly installed on the front end of the support frame 2. The winch frame 6 consists of a mounting frame 10, a first guide roller 11, and a second guide roller 12. There are two first guide rollers 11, which are symmetrically rotated vertically within the mounting frame 10. There are also two second guide rollers 12, which are symmetrically rotated horizontally within the mounting frame 10. The first guide roller 11 is located behind the second guide roller 12. A support frame 2, consisting of a square rod 8 and a connecting frame 9, is installed at the front end of the winch base 1. An installation slide 3, consisting of a round tube 13, a support slide 14, and an inner ring 17, is installed on the support frame 2. A water spray assembly 4, consisting of a main pipe 19, an annular pipe 20, and a nozzle 21, and a rotating ring 22, a limiting ring 23, a toothed ring 24, and brush bristles 21 are installed on the installation slide 3. 5. The brushing assembly 5, consisting of a servo motor 26 and gears 27, has a spray nozzle 21 on the front side of the water spray assembly 4 that can spray water onto the wound rope to initially rinse the mud on the rope surface. The servo motor 26 of the brushing assembly 5 can drive the brush bristles 25 to rotate and perform a second brushing of the rope. The spray nozzle 21 on the rear side of the water spray assembly 4 can spray water onto the rope after the second brushing to further clean the rope. The triple cleaning can effectively remove the mud attached to the surface of the rope, prevent the mud from contaminating the winch body 7, reduce the wear of the rope and the winch body 7, extend the service life of the equipment, and at the same time prevent the rope from getting stuck due to the drying and clumping of mud, ensuring the continuity and safety of exploration operations.A guide frame 6, consisting of a mounting frame 10, a first guide roller 11, and a second guide roller 12, is installed in front of the mounting carriage 3. The vertically symmetrical first guide roller 11 and the horizontally symmetrical second guide roller 12 can provide multi-directional limiting and guiding for the rope, ensuring that the rope maintains a stable trajectory as it passes through the mounting carriage 3, water spray assembly 4, and brushing assembly 5 during winding and unwinding, preventing rope deviation and ensuring that the rope can be cleaned normally and effectively. The mounting carriage 3 can slide along the square rod 8, allowing for flexible adjustment of the cleaning position according to the rope winding and unwinding position, improving cleaning adaptability and effectiveness.
[0016] Specifically, the connecting frame 9 on the support frame 2 is fixedly installed at the front end of the winch base 1 by bolts. The mounting slide 3 is located behind the guide frame 6. The support slide 14 is slidably installed on the square rod 8. Two sets of through holes 15 are opened in a ring on the front and rear sides of the round tube 13. A through groove 16 is opened on the upper side wall of the round tube 13 between the two sets of through holes 15. The inner ring 17 is located between the two sets of through holes 15. An annular groove 18 is opened on the inner wall of the inner ring 17. The main pipe 19 on the water spray assembly 4 is connected to the water supply equipment through a hose. Two annular pipes 20 are symmetrically fixed and sleeved on the round tube 13. The nozzle 21 passes through the through hole 15 and brushes the components on the assembly 5. The rotating ring 22 is rotatably installed inside the inner ring 17, the limiting ring 23 is rotatably installed in the annular groove 18, the toothed ring 24 is located in front of the inner ring 17, the servo motor 26 is fixedly installed on the upper outer wall of the circular tube 13, the gear 27 passes through the through groove 16, and the mounting bracket 10 on the guide frame 6 is fixedly installed at the front end of the two connecting frames 9 by bolts. In the process of core sampling for mining exploration, the winch body 7 is started first, and the winch body 7 begins to wind up the exploration rope. Under the action of the winding force, the rope drives the core drilling tool in the well to be slowly lifted until it is completely lifted to the ground. The workers then take out the collected rock core from the core drilling tool to complete one core sampling operation.
[0017] Furthermore, during the entire process of the winch body 7 winding the rope, the support frame 2 located at the front end of the winch base 1 is stably fixed to the winch base 1 through the connecting frame 9, providing a support foundation for subsequent components. The mounting slide 3 slides flexibly along the square rod 8 of the support frame 2 through the support slide 14, adjusting its position in real time according to the winding position of the rope on the winch body 7 to ensure that it corresponds to the rope winding trajectory. The main pipe 19 of the water spray assembly 4 continuously obtains water from the water supply equipment through the hose. The water flow is divided into two annular pipes 20 through the main pipe 19, and then sprayed out through the nozzles 21 installed on the annular pipes 20. The nozzle 21 located at the front sprays water flow onto the rope that has just entered the circular pipe 13 to initially wash the mud attached to the surface of the rope. Then, the servo motor 26 of the brushing assembly 5 is started. The output shaft of the servo motor 26 drives the gear 27 to rotate. The gear 27 meshes with the toothed ring 24 at the front end of the rotating ring 22, thereby driving the rotating ring. The rotating ring 22 rotates inside the inner ring 17. When the rotating ring 22 rotates, the bristles 25 on its inner wall rotate synchronously, which thoroughly scrubs the rope after the initial rinsing to further remove residual mud. At the same time, the limiting ring 23 rotates in the annular groove 18 to ensure the stable rotation of the rotating ring 22. Then, the nozzle 21 located at the rear sprays water again onto the scrubbed rope to wash away the scrubbed mud residue. The guide frame 6 located in front of the mounting slide 3 is fixed to the front end of the connecting frame 9 of the support frame 2 by the mounting frame 10. Before entering the mounting slide 3, the rope passes through the first guide roller 11 symmetrically arranged vertically and the second guide roller 12 symmetrically arranged horizontally in the guide frame 6. The first guide roller 11 and the second guide roller 12 limit and guide the rope in multiple directions to ensure that the rope always maintains a stable trajectory through the round pipe 13, the water spray component 4 and the scrubbing component 5, avoiding rope deviation that would affect the cleaning effect. Finally, the cleaned rope is smoothly wound up by the winch body 7.
[0018] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
