Description

Technical Field

[0001] This utility model relates to the field of slope measurement technology, and in particular to a slope meter for coal mine surveying. Background Technology

[0002] Coal mine surveying is used to accurately measure and analyze the geological conditions of mining areas, ensuring the safety and efficiency of mining operations. Inclinometers are used in coal mine surveying to measure the inclination angle of slopes or tunnels within the mine, helping to ensure the stability of the working environment and avoid dangerous accidents.

[0003] Inclinometers typically measure slopes by having their two right-angled sides in contact with the slope surface. After contact, rotating the scale wheel rotates the level tube, and observing the bubble level ensures the level tube is horizontal. The slope is then determined by reading the value on the scale. However, existing slope meters for coal mine surveying have shortcomings. First, after prolonged contact with rough surfaces such as ore, the right-angled sides of the slope meter are easily worn down, affecting normal use and requiring replacement of the entire meter, resulting in high costs. Second, after leveling the level tube during measurement, the scale wheel is prone to accidental rotation, leading to instability and deviations in the slope readings. This paper proposes a slope meter for coal mine surveying to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a slope meter for coal mine surveying, which aims to improve the existing technology where the right-angle side of the slope meter needs to be replaced after wear, resulting in high consumption costs. Also, after leveling the level tube of the slope meter during measurement, the scale rotating wheel is prone to accidental rotation due to instability, causing deviations in the read slope value.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a slope meter for coal mine surveying, comprising a slope meter body, a side plate engaged on one side of the slope meter body, a bottom plate engaged at the bottom of the slope meter body, slots provided on both sides of the bottom end of the side plate and both sides of one end of the bottom plate, inserts fixedly connected to the top of the side plate and the other end of the bottom plate, locking components installed at the four slots at the bottom of the slope meter body, a scale rotating wheel provided on one side of the top of the slope meter body, and a stop component installed on the front side of the slope meter body near the scale rotating wheel;

[0006] The locking assembly includes a connecting groove, a spring, and a locking block. The connecting groove is located at the bottom of the inclinometer body. A spring is fixedly connected to the inner wall of the connecting groove, and a locking block is fixedly connected to one end of the spring.

[0007] As a further description of the above technical solution:

[0008] One end of the card block engages with the inner wall of the card slot.

[0009] As a further description of the above technical solution:

[0010] The stop assembly includes a connecting seat, a spring, and a stop block. The connecting seat is fixedly connected to the front side of the inclinometer body. A spring is fixedly connected to the inner wall of the connecting seat, and a stop block is fixedly connected to one end of the spring.

[0011] As a further description of the above technical solution:

[0012] The front side of the connecting seat is provided with a dial opening, and the front side of the abutment is fixedly connected to a dial block, which is slidably connected to the inner wall of the dial opening.

[0013] As a further description of the above technical solution:

[0014] A rubber sheet is fixedly connected to one end of the spring.

[0015] As a further description of the above technical solution:

[0016] A scale is provided on one side of the surface of the slope meter body, and a level tube fixing ring is provided on the inner wall of the scale.

[0017] As a further description of the above technical solution:

[0018] The slope meter body has slots on both the bottom and top sides away from the side plate, and the two plugs are respectively inserted into the inner walls of the two slots.

[0019] As a further description of the above technical solution:

[0020] A handheld opening is provided on the side of the main body of the inclinometer away from the scale.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, side plates and bottom plates are provided at the two right-angled sides of the slope meter. When the slope meter is worn down after long-term measurement on the rough surface of a coal mine, the two locking blocks at the ends of the side plates can be pressed into the connecting grooves to release the lock. The side plates can then be removed and replaced with new ones. The locking blocks will engage in the locking slots under the action of springs, thus enabling the right-angled sides of the slope meter for coal mine surveying to be disassembled and replaced individually after wear, reducing cost consumption.

[0023] 2. In this utility model, after the right-angled edge of the slope meter is attached to the slope surface, the stop block at the stop component is moved, causing the abutment block to retract. At this time, the scale rotating wheel can be rotated to adjust the orientation of the level tube so that it is in a horizontal state. Then the stop block is released, and the rubber sheet at the end of the abutment block will press against the scale rotating wheel under the action of the spring force, increasing the resistance so that it will not be easily rotated, thereby avoiding the slope reading deviation caused by accidentally touching the scale rotating wheel during measurement.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3This utility model provides an embodiment of a slope meter for coal mine surveying, including a slope meter body 1 for measuring the slope of a coal mine slope. A side plate 2 is engaged on one side of the slope meter body 1, and a bottom plate 3 is engaged at the bottom of the slope meter body 1. These plates are installed on the two right-angled sides of the slope meter and can be worn. Slots 9 are provided on both sides of the bottom of the side plate 2 and on both sides of one end of the bottom plate 3. Inserts 4 are fixedly connected to the top of the side plate 2 and the other end of the bottom plate 3 to improve the installation stability of the side plates. Locking components are installed at the bottom of the slope meter body 1 at the four slots 9 to fix the position of the two side plates. A scale rotating wheel 10 is provided on one side of the top of the slope meter body 1 to adjust the orientation of the level tube. A stop component is installed on the front side of the slope meter body 1 near the scale rotating wheel 10 to limit the rotation of the scale rotating wheel 10.

[0032] Reference Figure 2 The locking component includes a connecting groove 6, a spring 7, and a locking block 8. The connecting groove 6 is located at the bottom of the inclinometer body 1. The inner wall of the connecting groove 6 is fixedly connected to the spring 7. One end of the spring 7 is fixedly connected to the locking block 8. Under the action of the spring force, the spring 7 will push the locking block 8 out of the connecting groove 6.

[0033] Reference Figure 2 One end of the locking block 8 engages with the inner wall of the locking slot 9, which can lock the side plate onto the slope meter body 1 and restrict its movement.

[0034] Reference Figure 4 The stop assembly includes a connecting seat 11, a spring 12, and a stop block 13. The connecting seat 11 is fixedly connected to the front side of the inclinometer body 1. The inner wall of the connecting seat 11 is fixedly connected to the spring 12. One end of the spring 12 is fixedly connected to the stop block 13. Under the elastic force of the spring 12, the stop block 13 will be pushed out of the connecting seat 11.

[0035] Reference Figure 1 and Figure 4 The front side of the connecting seat 11 is provided with a dial 16, and the front side of the abutment 13 is fixedly connected with a dial 15, and the dial 15 is slidably connected to the inner wall of the dial 16. The dial 16 provides space for the movement of the dial 15. By moving the dial 15, the abutment 13 is moved backward. At this time, the scale rotating wheel 10 can be rotated to adjust the orientation of the level tube.

[0036] Reference Figure 4 One end of the spring 12 is fixedly connected to a rubber sheet 14, which can increase friction and improve the anti-slip effect.

[0037] Reference Figure 1A scale 17 is provided on one side of the surface of the slope meter body 1. A level tube fixing ring 18 is provided on the inner wall of the scale 17. The right-angled edge of the slope meter is attached to the slope surface. Then, the scale rotating wheel 10 is rotated to adjust the orientation of the level tube so that it is horizontal. By observing the reading of the scale 17, the slope value of the location can be determined.

[0038] Reference Figure 3 The slope meter body 1 has slots 5 on the bottom and top sides away from the side plate 2, and two plugs 4 are respectively inserted into the inner walls of the two slots 5. The plugs 4 at one end of the two side plates are inserted into the slots 5, and the other end is locked by two locking blocks 8, so that they can be stably fixed on the slope meter body 1.

[0039] Reference Figure 1 A handheld opening 19 is provided on the side of the slope meter body 1 away from the scale 17. When measuring the slope of a coal mine, the hand can hold the handheld opening 19 for picking up and using the slope meter.

[0040] Working principle: The slope meter has side plates 2 and bottom plates 3 at its two right-angled edges. When worn down from prolonged use on rough coal mine surfaces, the two locking blocks 8 at the ends of the side plates can be pressed into the connecting grooves 6 to release the lock, allowing for removal and replacement of the side plates. The locking blocks 8, under the action of spring 7, engage with the locking slots 9, thus locking the right-angled edges of the slope meter. This allows for individual disassembly and replacement of the worn edges, reducing costs. After the right-angled edges of the slope meter are attached to the slope surface… Move the lever 15 at the stop assembly to retract the stop block 13. At this time, rotate the scale wheel 10 to adjust the orientation of the level tube to make it horizontal. Then release the lever 15. The rubber sheet 14 at the end of the stop block 13 will press against the scale wheel 10 under the elastic force of the spring sheet 12, increasing the resistance so that it will not be easily rotated. This avoids the slope reading deviation caused by accidentally touching the scale wheel 10 during measurement. After leveling the level tube, observe the reading on the scale 17 to determine the slope value at that location.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
