Description

Technical Field

[0001] This utility model relates to the field of drilling and sampling technology, and in particular to a core sampler for drilling on mine slopes. Background Technology

[0002] A mine slope coring tool is a specialized piece of equipment used for drilling operations on mine slopes. It is typically used to collect rock samples for rock mechanical property analysis, environmental monitoring, and mine safety assessments. In use, the entire core sampler is moved to the mine slope and placed. After starting the engine, the engine rotates the sampling cylinder via a chain and sprocket. The adjusting wheel rotates the screw, causing the lifting seat to descend, thus lowering the sampling cylinder for sampling. After sampling, the core sampler rises back to its original position. A limit rod on the adjusting wheel limits the movement of the lifting seat, ensuring it does not descend further during subsequent movements.

[0003] However, in existing core drills, the limiting rod needs to be operated to limit or unlock the adjusting wheel, which is extremely inconvenient. Furthermore, the limiting rod can only limit the adjusting wheel for a full number of turns, resulting in poor flexibility and adaptability. In addition, the limiting rod relies solely on gravity to descend and limit the wheel, which can easily become loose and move upwards, thus the limiting effect is generally poor. Utility Model Content

[0004] The main purpose of this utility model is to provide a core sampling tool for drilling on mine slopes, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A core drilling tool for mine slopes includes a base frame, a fixed column on the base frame, a lifting seat on the fixed column, a rotating seat on the lifting seat, a sampling cylinder below the rotating seat, a top plate at the upper end of the fixed column, a lead screw on the lifting seat with its upper end penetrating the top plate, an adjusting wheel at the upper end of the lead screw with a hexagonal groove on the adjusting wheel, a limiting structure that mates with the hexagonal groove fixed on the top plate, and a mounting plate on the lifting seat with an engine fixed on the mounting plate.

[0007] Preferably, the limiting structure includes a bracket, a mounting base, a limiting groove, a movable rod, and a limiting block. The bracket is fixedly connected to the mounting base, and the mounting base is fixed to the top plate by screws. The limiting groove is formed on the bracket. The movable rod and the limiting block are fixedly connected, and the movable rod passes through the bracket.

[0008] Preferably, the limiting structure further includes a hexagonal plug, an elastic component, and a knob. The hexagonal plug is fixed to the lower end of the movable rod, the elastic component is mounted on the movable rod, and the knob is mounted on the upper end of the movable rod.

[0009] Preferably, the elastic component includes an external thread, an adjusting plate, a spring, and a threaded hole. The external thread is disposed on the movable rod, the adjusting plate is fixedly connected to the spring, the threaded hole is opened on the adjusting plate, and the adjusting plate is connected to the movable rod through the threaded hole and the external thread. The upper end of the spring abuts against the bracket.

[0010] Preferably, the engine and the sampling cylinder are connected by a sprocket and a chain drive, a push rod is fixed on the base frame, and the base frame is equipped with casters and fixed wheels.

[0011] Compared with the prior art, this utility model has the following beneficial effects: This mine slope drilling core extractor, through the setting of a limiting structure, works in conjunction with the hexagonal groove on the adjusting wheel. While ensuring limiting, the hexagonal plug and hexagonal groove cooperate to limit the movement, eliminating the need to rotate the adjusting wheel a full circle to achieve limiting, thus improving operational convenience and providing a wider range of limiting angles. The use of limiting grooves and limiting blocks, in conjunction with an elastic component, ensures that the hexagonal plug at the lower end of the movable rod is assembled in the hexagonal groove during limiting, preventing the plug from falling off due to the movable rod rising, thus guaranteeing the limiting effect. The adjusting plate in the elastic component can be height-adjusted on the movable rod, thereby changing the relative compression of the spring and adjusting the elastic force, resulting in higher adaptability.

[0017] 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.

[0018] like Figures 1-4 As shown, a core drilling tool for mine slopes includes a base frame 1, a fixed column 2 on the base frame 1, a lifting seat 3 on the fixed column 2, a rotating seat 4 mounted on the lifting seat 3, and a sampling cylinder 5 below the rotating seat 4. A top plate 6 is located at the upper end of the fixed column 2. A lead screw 7 is mounted on the lifting seat 3, with its upper end penetrating the top plate 6. An adjusting wheel 8 is located at the upper end of the lead screw 7, and the adjusting wheel 8 has a hexagonal groove. A limiting structure 9 that mates with the hexagonal groove is fixed on the top plate 6. A mounting plate 10 is mounted on the lifting seat 3, and an engine 11 is fixed on the mounting plate 10. The engine 11 is connected to the sampling cylinder 5 via a sprocket and chain drive. A push rod 12 is fixed on the base frame 1, and the base frame 1 is equipped with casters 13 and fixed wheels 14.

[0019] When using a core drill to sample mine slopes, the entire core drill is moved using the casters 13 and fixed wheels 14 on the base frame 1. Once the core drill is positioned at a suitable location on the slope and stabilized, the engine 11 on the mounting plate 10 is started. The engine 11 drives the sampling cylinder 5 via sprockets and chains, causing the sampling cylinder 5 to rotate on the rotating seat 4. Simultaneously, the limiting structure 9 is activated, causing it to move aside. Then, the adjusting wheel 8 rotates the lead screw 7, which drives the lifting seat 3 to descend along the fixed column 2, thus lowering the rotating seat 4, sampling cylinder 5, mounting plate 10, and engine 11. The sampling cylinder 5 then samples the mine slope. After sampling, the adjusting wheel 8 drives the rotating seat 4, sampling cylinder 5, mounting plate 10, and engine 11 to rise again. The limiting structure 9 then limits the adjusting wheel 8. Finally, the sample from the sampling cylinder 5 is removed for subsequent testing.

[0020] According to the above implementation scheme, the limiting structure 9 includes a bracket 901, a mounting base 902, a limiting groove 903, a movable rod 904, and a limiting block 905. The bracket 901 is fixedly connected to the mounting base 902, and the mounting base 902 is fixed to the top plate 6 by screws. The limiting groove 903 is formed on the bracket 901. The movable rod 904 and the limiting block 905 are fixedly connected, and the movable rod 904 passes through the bracket 901. The limiting structure 9 also includes a hexagonal plug 906, an elastic component 907, and a knob 908. The hexagonal plug 906 is fixed to the lower end of the movable rod 904, the elastic component 907 is installed on the movable rod 904, and the knob 908 is installed on the upper end of the movable rod 904.

[0021] The elastic component 907 includes an external thread 9071, an adjusting plate 9072, a spring 9073, and a threaded hole 9074. The external thread 9071 is provided on the movable rod 904. The adjusting plate 9072 is fixedly connected to the spring 9073. The threaded hole 9074 is opened on the adjusting plate 9072, and the adjusting plate 9072 is connected to the movable rod 904 through the threaded hole 9074 and the external thread 9071. The upper end of the spring 9073 abuts against the bracket 901.

[0022] Before sampling, the movable rod 904 in the limiting structure 9 is at its lowest position, and the hexagonal plug 906 is located in the hexagonal groove on the adjusting wheel 8. When sampling is required, the movable rod 904 is pulled up by the knob 908, and the hexagonal plug 906 moves out of the hexagonal groove. The limiting block 905 then moves out of the limiting groove 903. At the same time, the adjusting plate 9072 in the elastic component 907 rises to compress the spring 9073. Rotating the knob 908 ninety degrees causes the movable rod 904 to rotate ninety degrees along with the limiting block 905. After releasing the knob 908, the adjusting plate 9072, along with the movable rod 904, descends under the action of the spring 9073 until the limiting block 905 contacts the bracket 901. At this point, the hexagonal plug 906 is above the hexagonal groove and has no limiting effect on the adjusting wheel 8. The operator then rotates the adjusting wheel 8 to rotate the screw 7, thereby adjusting the height of the lifting seat 3.

[0023] When it is necessary to limit the adjustment wheel 8, move the movable rod 904 upward and rotate it 90 degrees as described above. The limiting block 905 aligns with the limiting groove 903. After releasing the knob 908, the movable rod 904 descends under the action of the spring 9073, and the limiting block 905 inserts into the limiting groove 903. The hexagonal plug 906 then connects to the hexagonal groove, thereby limiting the adjustment wheel 8. Under the elastic action of the spring 9073, the movable rod 904 tends to move towards the adjustment wheel 8, which can prevent the hexagonal plug 906 from falling off due to movement, ensuring the limiting effect.

[0024] When needed, the adjusting plate 9072 can be rotated. The adjusting plate 9072 moves on the movable rod 904 through the threaded hole 9074 and the external thread 9071, thereby changing the compression effect of the spring 9073. This allows for the adjustment of the elastic force. The structure is simple and the performance is excellent.

[0025] It should be noted that by using the limiting structure 9 in conjunction with the hexagonal groove on the adjusting wheel 8, the hexagonal plug 906 can achieve limiting while ensuring the limiting function. This eliminates the need to rotate the adjusting wheel 8 a full circle to achieve the limiting function, resulting in greater ease of operation and a wider range of limiting angles. The limiting groove 903 and limiting block 905, used in conjunction with the elastic component 907, ensure that the hexagonal plug 906 at the lower end of the movable rod 904 is properly fitted into the hexagonal groove during limiting, preventing the plug 906 from falling off when the movable rod 904 rises, thus ensuring the limiting effect. The adjusting plate 9072 in the elastic component 907 can be height-adjusted on the movable rod 904, thereby changing the relative compression of the spring 9073 and adjusting the elastic force, resulting in greater adaptability.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
