Description

Technical Field

[0001] The utility model relates to the technical field of exploration and measurement equipment, in particular to a depth measurement device for exploring a goaf area in a mine. Background Art

[0002] Mine goaf refers to underground hollow areas formed by the gradual emptying of space originally supported by ore or surrounding rock during the mining process of underground mineral resources as ore is excavated and transported out. Since these areas have lost their original supporting structures, the stability and stress balance of the upper rock layers will be affected, which may lead to geological disasters such as ground collapse, cracks, and subsidence, posing a potential threat to the surrounding ecological environment, building safety, and human activities;

[0003] Therefore, the management and monitoring of mine goafs are important contents of sustainable development and environmental protection of the mining industry. When measuring the depth of mine goafs, drilling is generally used to drill into the goafs, and cables and other mechanisms are used to measure the depth of the goafs from below. For example, the Chinese utility model patent disclosed by announcement number CN213812082U: a portable goaf filling height measuring device, the application includes a winding device, the winding end of the winding device is wound with a measuring rope, and the end of the measuring rope is installed with a counterweight block to solve the problem that the height of the goaf filling surface, the remaining height of the goaf filling, and the depth of the inclined filling borehole are difficult to measure. Although the application can measure the depth of the goaf, when measuring the depth of the goaf, it is impossible to collect the rock and soil samples in the goaf, and the rock and soil of different regions and types have different engineering properties. Through sampling and analysis, the type and structural characteristics of the rock and soil in the goaf can be clarified, providing a basis for formulating targeted management plans. Therefore, when measuring the depth of the goaf, the application cannot achieve more extended functions. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-Figure 5 As shown, the utility model provides a depth measuring device for exploring a mine goaf, comprising a pay-off frame 1 and a depth detection mechanism 2, wherein a motor 3 is fixedly mounted on one side of the pay-off frame 1, a control box 4 is also fixedly mounted on the pay-off frame 1 below the motor 3, and the motor 3 is electrically connected to the control box 4 via a connecting line, and the depth detection mechanism 2 further comprises a carrier ring 5, a plurality of connecting rods 6 are movably mounted on the outer side of the carrier ring 5, and two connecting rods 6 form a group, an expansion rod 7 is movably mounted between the two connecting rods 6, a sampling shovel 8 is fixedly mounted on one side of the expansion rod 7, and a counterweight plate 10 is movably connected between the three expansion rods 7.

[0026] like Figure 2-Figure 4As shown, three fixing rods 11 are fixedly installed on the outside of the carrier ring 5. Through the arrangement of the carrier ring 5 and the three fixing rods 11, a basic point for installing the connecting rod 6 can be provided. Two connecting pins 12 are inserted and connected between the two connecting rods 6, and one end of the connecting rod 6 is rotatably installed on one end of the fixing rod 11 through one of the connecting pins 12. A fixing ring 13 is fixedly installed on the top of the expansion rod 7, and an arc-shaped guide rod 14 is fixedly installed on one side of the expansion rod 7. Both sides of the expansion rod 7 and the arc-shaped guide rod 14 are provided with a connecting driving guide groove 15. The top of the expansion rod 7 is rotatably installed on the opposite side through the fixing ring 13. The expansion rod 7 should be rotatably installed on one of the connecting pins 12 between the two connecting rods 6 through the fixing ring 13 on the corresponding connecting pin 12, so that the expansion rod 7 can be rotated with the fixing ring 13 as the axis, thereby driving the sampling shovel 8 to be retracted and released. A mounting groove 16 is provided in the middle position of one side of the sampling shovel 8, and a fixing seat 17 is fixedly installed on the side of the sampling shovel 8 opposite to the mounting groove 16. The sampling shovel 8 is inserted and installed on one side of the expansion rod 7 through the mounting groove 16 and fixed by screws. When the expansion rod 7 drives the sampling shovel 8 to be retracted and released, the rock and soil samples in the goaf can be collected.

[0027] like Figure 2-Figure 5 As shown, three slide grooves 19 are opened on the outside of the counterweight plate 10, and sliders 20 are fixedly installed on both sides of the slide grooves 19. A suspension rod 9 is fixedly installed at the center position of the top of the counterweight plate 10. The counterweight plate 10 is installed between the three expansion rods 7 through the three slide grooves 19 on the outside, and the slider 20 is slidably installed in the corresponding guide groove 15. The top of the suspension rod 9 passes through the load ring 5 and extends to the position above the load ring 5 and is fixedly installed with a suspension ring 18. The suspension ring 18 is movably connected to one end of the connecting rope in the wire pay-off frame 1. Through the setting of the counterweight plate 10, when the bottoms of the three sampling shovels 8 contact the bottom of the goaf, the weight of the counterweight plate 10 can be used to squeeze and expand the three expansion rods 7 outward.

[0028] It should be noted that the utility model is a depth measuring device for exploring a goaf in a mine. When measuring the depth of the goaf, the user can first hold the cable connected to the lifting ring 18 by hand, thereby lowering the entire depth detection mechanism 2 into the borehole pre-opened by the drilling rig. Then, the motor 3 can be started through the control box 4, so that the output end of the motor 3 drives the roller in the pay-off frame 1 to rotate, thereby uniformly passing the depth detection mechanism 2 through the bottom of the borehole to the goaf through the cable. When the three sampling shovels 8 touch the bottom, the cable continues to go down for a certain length, so that the counterweight plate 10 descends by its own weight, and the counterweight plate 10 can slide between the three fixed seats 17 through the three outer slide grooves 19, and the two sliders 20 in the slide groove 19 slide down in the corresponding guide groove 15, so that the counterweight plate 10 cooperates with the arc-shaped guide rod 14 to move the fixed seat 17 outward. The three fixing seats 17 are synchronously driven to expand the three sampling shovels 8, and the corners of the sampling shovels 8 are inserted into the soil layer in the goaf. After the depth in the goaf is measured according to the lower length of the cable, the cable is wound up by the motor 3 and the rotating shaft in the pay-off frame 1, so that the cable lifts the boom 9 through the lifting ring 18, and the boom 9 drives the counterweight plate 10 to move up. Then, the boom 9 retracts the three expansion rods 7 through the sliders 20 in the three outer slide grooves 19, so that the corners of the three sampling shovels 8 shovel a certain amount of soil in the goaf, and the three sampling shovels 8 are combined so that the sample is stored in the three sampling shovels 8, and the whole depth detection mechanism 2 can be raised by the cooperation of the cable and the pay-off frame 1.
