Description

Technical field:

[0001] The utility model belongs to the field of mine mining mechanical equipment, in particular to a coal mining drainage drill rod cleaning and wiping device. Background technology:

[0002] Drill pipe is a steel pipe with a threaded tail, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or bottom hole device at the bottom of the well.

[0003] In order to solve the problem of water accumulation between coal seams during coal mining, drill rods are used to drill holes to drain the accumulated water by gravity. Since the mining surface of the mine is long, a large number of drill rods are required for a single drilling operation. After the drilling operation is completed, the drill rod installed on the drilling rig needs to be removed and the stains attached to its surface need to be rinsed. After the drill rod is rinsed, the water stains remaining on the surface of the drill rod need to be wiped clean to prevent the water stains from causing rust and corrosion on the outer surface of the drill rod, so as to ensure the normal use of the drill rod in the later stage. In the actual process, after the drill rod is rinsed, the on-site operators need to hold a wiping cloth to wipe the water stains, but this method is likely to result in unclean wiping of the water stains, and water stains will still remain on the surface of the drill rod, causing rust and corrosion on the surface of the drill rod. In addition, the drill rods are long and the number is large. Manual wiping is not only inefficient, but also increases the workload of on-site operators. Utility model content:

[0004] The utility model aims to provide a cleaning and wiping device for a coal mining drainage drill rod, and overcomes the deficiencies of the above-mentioned prior art, and effectively solves the existing problem that water stains cannot be wiped clean after the drill rod is cleaned.

Specific implementation method:

[0017] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation of the present invention is now described with reference to the accompanying drawings:

[0018] like Figures 1 to 4As shown, a coal mining drainage drill rod cleaning and wiping device comprises a cleaning box 1, both ends of the cleaning box 1 are provided with through openings 2, both sides of the through openings 2 are provided with sponge rollers 3, the sponge rollers 3 are located in the inner cavity of the cleaning box 1, both ends of the sponge rollers 3 are rotatably connected with bearing seats 4, the bearing seats 4 are mounted on a transverse plate 5, the transverse plate 5 is mounted on the inner wall of the cleaning box 1, one end of the sponge roller 3 is transmission-connected with a drive motor 6, the drive motor 6 is mounted on the transverse plate 5, roller groups 7 are installed on the top wall and the bottom wall of the inner cavity of both ends of the cleaning box 1, a wiper assembly is arranged in the cleaning box 1, the wiper assembly is used to scrape out the water adsorbed by the sponge roller 3, and inspection openings 16 are provided on the two side walls of the cleaning box 1, and a switch door 17 is provided on the inspection opening 16, and the switch door 17 is hinged on the side wall of the cleaning box 1.

[0019] Specifically, the sponge roller 3 can be used to wipe away the water stains remaining on the surface of the drill rod 19 .

[0020] During actual use, one end of the removed drill rod 19 is inserted into the through opening 2. At this time, the roller group 7 installed on the top wall and the bottom wall at both ends of the inner cavity of the cleaning box 1 not only plays a role in auxiliary transmission, but also can support and clamp the drill rod 19 to ensure that the drill rod 19 remains coaxial with the through opening 2 when entering the cleaning box 1. At this time, the two started drive motors 6 rotate in the same direction and drive the corresponding sponge rollers 3 to rotate. The rough outer surface of the sponge roller 3 rubs against the outer surface of the drill rod 19 and drives the drill rod 19 to rotate. At this time, the sponge roller 3 absorbs the water stains remaining on the surface of the drill rod 19, and the wiper assembly can scrape the water stains absorbed by the sponge roller 3 for temporary storage to maintain the normal absorption rate of the sponge roller 3. When the sponge roller 3 is severely worn during use, the switch door 17 can be opened and it can be replaced through the inspection port 16.

[0021] like Figures 1 to 4As shown, a coal mining drainage drill rod cleaning and wiping device, the scraping assembly includes a vertically arranged scraper 8, an elastic support assembly is arranged on the scraper 8, the elastic support assembly is installed on the top wall of the water storage tank 9, the water storage tank 9 is installed on the bottom wall of the inner cavity of the cleaning box 1, the top end of the scraper 8 is squeezed and slid with the outer surface of the sponge roller 3, and a water receiving port 10 matching the scraper 8 is opened on the top wall of the water storage tank 9, and the water receiving port 10 is located directly below the scraper 8. The elastic support assembly includes vertically arranged on both sides of the scraper 8. A straight-mounted support arm 11 has a collar 12 installed at the outer end of the support arm 11, and the collar 12 is slidably mounted on a vertical pole 13, and the vertical pole 13 is vertically mounted on the top wall of the water tank 9, and an anti-drop cap is installed on the top of the vertical pole 13, and a spring 14 is mounted on the vertical pole 13, and the spring 14 is located below the collar 12. A storage edge 15 is provided on the water receiving port 10, and the storage edge 15 is mounted on the top wall of the water tank 9, and a drain pipe 18 is installed on the water tank 9, extending to the outside of the cleaning box 1.

[0022] Specifically, the water stains absorbed by the sponge roller 3 can be quickly scraped out by the wiper assembly to maintain the normal absorption rate of the sponge roller 3 .

[0023] During actual use, when the sponge roller 3 absorbs a lot of water stains, the vertically arranged scraper 8 squeezes and slides with the outer surface of the sponge roller 3 to squeeze out the absorbed water stains, and the squeezed water flows into the water receiving port 10 below and is finally temporarily stored in the water storage tank 9; the storage edge 15 further prevents the water from falling out of the water storage tank 9; the spring 14 can make the ring 12 always at the top of the vertical pole 13, so that the top of the scraper 8 is squeezed and slid with the outer surface of the sponge roller 3 at all times, to ensure that the water in the sponge roller 3 can be efficiently squeezed out; when the amount of water temporarily stored in the water storage tank 9 is large, the valve on the drain pipe 18 can be opened to discharge the water.

[0024] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
