Description

Technical Field

[0002] Mine tunnels are a general term for various underground spaces that are excavated in different rocks along different directions, at different inclinations, in different sections and lengths, and serve different ranges and for different purposes. The construction of coal mine tunnels needs to be carried out according to the designed slope. In related technologies, it is necessary to use a level and a laser to measure the slope of the tunnel to avoid errors. However, in the measurement process of tunnels with large differences in inclination, the laser rotates with the rotation of the level. If the rotation rate is too fast, the equipment jitter will increase, which will easily lead to low positioning accuracy. If the rotation rate is too slow, it will easily lead to a long measurement time, affecting the construction progress. Utility Model Content

The driving assembly 4 includes a driving part 41 and a transmission part 42. The first end of the transmission part 42 is connected to the driving part 41, and the transmission part 42 is rotatable around the second axial direction. The second end of the transmission part 42 is connected to the second end of the level ruler 2. The driving part 41 is used to drive the transmission part 42 to move in the first direction (i.e. Figure 1The transmission part 42 drives the level ruler 2 to rotate, the first direction is orthogonal to the first axial direction, and the first axial direction is parallel to the second axial direction.

[0035] Specifically, Figure 1 As shown, the level 2 is arranged in the front-to-back direction, the front end of the level 2 can be matched with the frame 1 through the shaft hole, and the rear end of the level 2 can rotate relative to the frame 1 around the shaft. The laser instrument 3 is arranged above the level 2, and the laser instrument 3 and the level 2 can be connected by plugging (that is, the laser instrument 3 and the level 2 are interference fit through the hole shaft), or by threaded connection.

[0036] It can be understood that the driving part 41 is a device that provides moving power for the transmission part 42, such as a cylinder, a telescopic motor or a linear module, etc. The lower end of the transmission part 42 is connected to the driving part 41, and the upper end of the transmission part 42 is connected to the rear end of the level 2, so that when the driving part 41 drives the transmission part 42 to move in the front-back direction, the transmission part 42 moves and drives the level 2 to rotate.

[0037] Optionally, the driving part 41 may be a guide rail, a guide member of the guide rail is connected to the frame body 1 , and a moving member of the guide rail is connected to the first transmission member 421 .

[0038] That is to say, the slope detection device used in underground tunnels of coal mines of the utility model can rotate the transmission part 42 around the second axis to change the inclination angle of the transmission part 42, thereby changing the rate at which the level ruler 2 is driven to rotate by the transmission part 42, so that the slope detection device can be used in scenes with large slope changes, and has the advantage of a wide range of uses.

[0039] In other words, the utility model can set the inclination angle of the transmission part to be close to the inclination degree of the laneway, so that the speed of moving the transmission part and driving the horizontal ruler to rotate can be kept stable, which is beneficial to reducing the jitter of the equipment.

[0040] It should be noted that if Figure 2 and Figure 3 As shown, the greater the inclination angle of the transmission part 42 is, the faster the speed of the level 2 is rotated.

[0041] Optionally, the transmission part 42 includes a first transmission member 421 and a second transmission member 422, the first transmission member 421 and the second transmission member 422 are detachably connected, and the first transmission member 421 is rotatable relative to the second transmission member 422, and at least part of the first transmission member 421 is connected to the driving part 41.

[0042] Specifically, Figure 1As shown, the lower end of the first transmission member 421 is connected to the driving part 41, so that the driving member can drive the first transmission member 421 to move when it is started. The second transmission member 422 can be connected to the first transmission member 421 through a shaft hole, or the second transmission member 422 and the first transmission member 421 are connected by bolts to fasten the first transmission member 421 and the second transmission member 422.

[0043] Optionally, the slope detection device for underground mine tunnels of the utility model further includes a first connecting member 5, the second transmission member 422 has a slide groove 4221, the extension direction of the slide groove 4221 is consistent with the extension direction of the second transmission member 422, and the slide groove 4221 is along the thickness direction of the second transmission member 422 (such as Figure 1 The first end of the first connecting member 5 passes through the slide groove 4221 and is detachably connected to the second end of the level ruler 2.

[0044] Specifically, if Figure 1 As shown, a connecting hole is provided on the second end of the level 2 (i.e., the rear end of the level 2), and the left end of the first connecting member 5 passes through the slide groove 4221 and fits in the connecting hole to connect the level 2 and the first connecting member 5.

[0045] Preferably, the first connecting member 5 can be a screw, and the connecting hole is a threaded hole. Then, the stud of the first connecting member 5 can fit into the connecting hole after passing through the slide groove 4221, thereby fixing the first connecting member 5 and the level 2 and facilitating disassembly.

[0046] Optionally, the slope detection device for underground coal mine tunnels of the utility model further includes a second connecting member 6 , and the second connecting member 6 is used to connect the first transmission member 421 and the second transmission member 422 .

[0048] It is understandable that when the tilt angle of the second transmission member 422 needs to be adjusted, the second connecting member 6 can be loosened, and then the second transmission member 422 is adjusted to the desired tilt position and the second connecting member 6 is tightened to achieve the function of adjusting the second transmission member 422.

[0049] Optionally, the frame 1 includes a base 11 and an extension portion 12 , a first end of the extension portion 12 is connected to the base 11 , and a second end of the extension portion 12 is connected to a first end of the level 2 .

[0052] Specifically, Figure 1 As shown, the correction opening 71 is arranged along the front-rear direction through the correction part 7. When the laser instrument 3 is started, the optical signal generated by the laser instrument 3 can pass through the correction opening 71 and be emitted into the lane to be measured, so as to measure the lane.

[0053] It is understandable that after long-term use, when one of the laser instrument 3 or the correction part 7 is misaligned or deformed, the optical signal generated by the laser instrument 3 is easily blocked by the correction part 7, resulting in measurement failure.

[0057] It is understandable that if Figure 1 As shown, the fitting portion 81 is movable relative to the base 11 in the up-down direction so as to be able to adjust the depth of the tip portion 82 inserted into the ground.
