Description

Technical Field

[0001] This invention relates to the field of mine pipeline dredging technology, and in particular to a mine underground filling pipeline dredging device. Background Technology

[0002] In mining operations, underground backfilling pipelines are crucial facilities for ensuring the stability of goaf areas and preventing surface subsidence. However, due to factors such as unevenness of backfill materials, wear on the inner walls of the pipelines, and improper operation, backfilling pipelines often experience blockages, severely impacting mine production efficiency and safety. The length of underground backfilling pipelines varies depending on the specific conditions and mining needs of the mine, and mainly includes three types: trunk backfilling pipes, working face backfilling pipes, and backfilling pipes. Among them, the backfilling pipes laid from the ground to the lower roadway are called trunk backfilling pipes, which can reach several kilometers in length. Pipes entering the working face are called working face backfilling pipes, which can reach several hundred meters in length. Backfilling pipes are those that branch off from the working face backfilling pipes at regular intervals to deliver paste to the goaf area, and can reach several meters in length.

[0003] Chinese utility model patent with publication number CN202105824U discloses a dredging device for underground filling pipes in mines. When using this device, a lightweight down-the-hole drill with a drill rod diameter suitable for the diameter of the wear-resistant steel filling pipe is selected. The wear-resistant steel filling pipe is installed and fixed on the wear-resistant steel filling pipe support with several clamps, so that the center line of the inner hole of the wear-resistant steel filling pipe is on the same line as the center line of the drill rod. The drill rod of the dredging device is inserted into the wear-resistant steel filling pipe to clean the blockage filler.

[0004] When using existing underground filling pipe dredging tools for clearing short filling pipes (approximately a few meters in length), a drill rod is often inserted through the pipe joint, inspection port, valve, or special dredging hole. High-pressure water jets or drill bits are used to remove the blockage. However, due to limitations in the location of pipe joints, a straight drill rod creates dead angles, making it difficult to adjust the direction and affecting the construction progress.

[0025] Reference Figure 2The first adjustment assembly 31 includes a base 311, a first drive source 312, a first support 313, a first gear 315, a first telescopic cylinder 316, and a first hydraulic cylinder 317. The base 311 is fixedly installed on one side of the base 2. The first drive source 312 is fixedly installed on the circumferential surface of the base 2. The first support 313 is rotatably connected to the base 311, and the outer circumferential surface of the first support 313 has a first tooth 314.

The first teeth 314 mesh with each other, the first telescopic cylinder 316 is fixedly installed on one side of the first support 313, and the end of the first telescopic cylinder 316 away from the base 311 is inclined, that is, the connection between the first telescopic cylinder 316 and the second adjusting component 32 is at a certain angle to the horizontal plane, and because of the inclination, the cross section of the inclined end is elliptical. The fixed part of the first hydraulic cylinder 317 is fixedly installed on the first support 313, and the output end of the first hydraulic cylinder 317 is fixedly connected to the movable end of the first telescopic cylinder 316.

[0026] Reference Figure 3 The second adjustment assembly 32 includes an adjustment shim 321, a second drive source 322, a second support 323, a second gear 325, a second telescopic cylinder 326, and a second hydraulic cylinder 327.

The inclination direction of the second telescopic cylinder 326 near the first adjusting component 31 is opposite to that of the first telescopic cylinder 316, but the cross sections of the inclined ends of the first telescopic cylinder 316 and the second telescopic cylinder 326 match. At the same time, the inclinations on both sides of the second telescopic cylinder 326 are mirror-symmetrically distributed. The fixed part of the second hydraulic cylinder 327 is fixedly installed on the fixed cylinder of the second telescopic cylinder 326, and the output end of the second hydraulic cylinder 327 is fixedly connected to the movable end of the second telescopic cylinder 326.

[0028] Reference Figure 5 The control device 4 includes an intelligent interactive screen 41 and a joystick 42, both of which are mounted on one side of the top of the bracket 1. Users can install different construction tools on the tool mounting platform 5 according to different usage scenarios. During changes in direction and position, the tool mounting platform 5 images the working environment and transmits the images to the intelligent interactive screen 41 for display. Users control the joystick 42 to operate the adjustment device 3. The intelligent interactive screen 41 has a built-in PLC controller and is electrically connected to an external power source. The joystick 42 is controlled by an internal PLC programming program. The tool mounting platform 5 is electrically connected to an external power source and is also controlled by an internal PLC programming program.

[0029] In addition, both the adjusting shim 321 and the functional shim 331 are circular and fixed on an inclined elliptical cross section. The inclination angle of the inclination is variable, including but not limited to 30°, 35°, 40° and 45°. However, regardless of the angle, the inclination of the first telescopic cylinder 316 and the inclination of the third telescopic cylinder 336 are always mirror-symmetrically distributed. The inclinations on both sides of the second telescopic cylinder 326 are always mirror-symmetrically distributed. The inclination angle of the first telescopic cylinder 316 is the same as the inclination angle of the side of the second telescopic cylinder 326 closest to the first telescopic cylinder 316.

The first hydraulic cylinder 317, the second hydraulic cylinder 327 and the third hydraulic cylinder 337 are controlled by an internal PLC programming program.

[0031] The implementation principle of a mine underground filling pipe dredging device according to an embodiment of the present invention is as follows:

[0032] The bracket 1 supports the other parts of the device. The base 2 serves as the mounting platform for the adjustment device 3 and also acts as a counterweight to prevent the device from tipping over due to instability of the center of gravity caused by changes in the length direction of the adjustment device 3 during operation. The control device 4 is used to observe the working environment and control the adjustment device 3 and construction tools. The tool mounting platform 5 is compatible with various tools such as high-pressure water guns and drill bits, and can be replaced according to different working environments. The tool mounting platform 5 has a built-in camera (not shown in the figure) that can image the working environment and transmit it to the control device 4. The user controls the adjustment device 3 and construction tools through the control device 4.

[0033] In addition, due to different blockage locations, the user needs to continuously adjust the position and direction of the construction tool. The first adjustment component 31 is used for the first stage of direction adjustment. The first drive source 312 is activated, driving the first gear 315 to rotate, which in turn drives the first support 313, which meshes with the first gear 315 through the first toothed teeth 314, to rotate. The base 311 has a circular cross-section and is used to support and assist the rotation of the first support 313, completing the direction change. One end of the first telescopic cylinder 316, fixedly connected to the output end of the first hydraulic cylinder 317, can move relative to its other end. After completing the extension and retraction of the first telescopic cylinder 316, when a change in length is required, the first hydraulic cylinder 317 is controlled to extend and retract, thereby driving the first telescopic cylinder 316 to extend and retract to change its length. Due to the variety of possible blockage locations, a single-dimensional directional change is insufficient to meet the requirements, and a second-stage directional change is needed. The implementation principle of the second adjustment component 32 is the same as that of the first adjustment component 31. In order to increase the flexibility of the adjustment device 3, a third-stage directional change is required. The implementation principle of the functional component 33 is the same as that of the first adjustment component 31 and the second adjustment component 32.

Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component.
