Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mine drilling maintenance technology, specifically relating to a mine drilling dredging device. Background Technology
[0002] Mining companies currently drill holes primarily for various purposes, including exploration, backfilling, drainage, cable holes, blasting holes, and raise boring machine (RBD) rig pilot holes. These types of holes are frequently blocked during use and maintenance due to foreign objects and debris falling into them, especially drainage, cable, and RBD rig pilot holes connecting two horizontal levels. Currently, there are three main technical methods for handling hole blockages:
[0003] 1. Using the original drilling equipment for dredging is a method with high labor and material costs, and it also has a certain impact on the drilling equipment construction plan and mine production organization.
[0004] 2. Using blasting is a high-risk method. The amount of explosives used is difficult to control, and it has a significant destructive effect on the borehole. Improper handling can affect the function of subsequent drilling and may even cause the drilling to fail.
[0005] 3. For boreholes that cannot be cleared or are severely blocked, redesign and construction are required, which increases production costs as well as time and management costs.
[0006] Therefore, it is essential to develop a mine borehole clearing device that is simple to manufacture, easy to use, and facilitates rapid resumption of production. Utility Model Content
[0007] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a mine borehole clearing device.
[0008] The purpose of this utility model is achieved as follows: it includes a rod body, an impact head, a hanging ring, an annular sleeve, and balls. The rod body is an externally threaded rod with internally threaded holes at both the upper and lower ends. The upper end of the impact head is a screw, which is threadedly connected to the internally threaded hole at the lower end of the rod body. The bottom of the hanging ring is provided with a screw, which is threadedly connected to the internally threaded hole at the upper end of the rod body. The annular sleeve is provided with internal threads, and several balls are embedded in the outer side of the annular sleeve along its circumference. There are multiple annular sleeves, which are respectively fitted onto the outside of the rod body from bottom to top, with the lowest annular sleeve abutting against the impact head.
[0009] Among them, the ball bearing is a common component in the field, such as a steel ball, which can be embedded in the cavity of the annular sleeve. The cavity can accommodate the ball bearing, while a part of the ball bearing protrudes out of the annular sleeve.
[0010] Preferably, the rod is a solid rod, specifically made of carbon steel.
[0011] Preferably, the length of the rod is 0.5m to 2m.
[0012] Preferably, the impact head is a conical head or an impact head with barbs. The barbs are used to catch debris, which is lifted and carried out during the recovery process of the upper part of the rod.
[0013] Preferably, the hanging ring is bound with a rope, and the rope is connected to a winding device, which is a commonly used tool in the art, such as a winding handwheel.
[0014] Preferably, each annular sleeve has four balls, more preferably six.
[0015] The beneficial effects of this utility model are as follows: This utility model utilizes impact to unclog various drill holes in mines that are blocked by falling foreign objects. It is easy to operate and can be done manually by a single person. In particular, for drainage drill holes with a construction angle >60° and which are often easily blocked by foreign objects, as well as large downward T150 holes, this device has a significant unblocking effect, is highly efficient and convenient, and achieves the unblocking purpose while avoiding excessive consumption of time, manpower and materials. Moreover, the structure is simple and easy to process. If some ball bearings of this device are damaged after long-term use, it is only necessary to unscrew the ring sleeve and replace the corresponding ring sleeve, which is very convenient. This device can also be replaced with ring sleeves and impact heads of different specifications and sizes as needed, making it widely applicable. Attached Figure Description

[0021] The present invention will be further described below with reference to the embodiments and accompanying drawings, but this does not limit the present invention in any way. Any changes or substitutions made based on the teachings of the present invention shall fall within the protection scope of the present invention.
[0022] Example 1
[0023] As attached Figures 1-3As shown, the mine drilling and dredging device of this embodiment includes a rod body 1, an impact head 2, a hanging ring 3, an annular sleeve 4, and ball bearings 5. The rod body 1 is a solid carbon steel rod with a length of 1.5m and a diameter of 30mm. The rod body 1 is an externally threaded rod with internally threaded holes at both the upper and lower ends. The impact head 2 is a conical head with a screw at the upper end, which is threaded to the internally threaded hole at the lower end of the rod body 1. The hanging ring 3 has a screw at the bottom, which is threaded to the internally threaded hole at the upper end of the rod body 1. The hanging ring 3 is bound with a 50-meter rope, which is connected to a winding device. The annular sleeve 4 has internal threads, and four ball bearings 5 are embedded on the outside of the annular sleeve 4 along its circumference. The annular sleeve 4 is 5cm high, and there are 30 annular sleeves in total, which are fitted onto the outside of the rod body 1 from bottom to top, with the lowest annular sleeve 4 abutting against the impact head 2.
[0024] The working principle and process of this utility model are as follows: This device is usually used in conjunction with a rope tied to the hanging ring 3. When in use, the device is lowered from the top of the blockage hole, and the device uses its own weight to impact the debris downwards. The ball bearings 5 contact and roll with the hole wall, avoiding direct friction between the rod 1 and the hole wall, thus enhancing the impact effect. After impact, the rope is retrieved. Repeated impacts are made to flush out the debris and clear the blockage hole. If the ball bearings 5 of the annular sleeve 4 become deformed after long-term use, affecting normal rolling, the annular sleeve 4 can be unscrewed and removed, and then replaced with a new annular sleeve 4.
