Description

Technical Field

[0001] This invention relates to the field of guidance measurement equipment in mine roadway and tunnel construction, and particularly to an integrated laser guidance device for centerline and waistline. Background Technology

[0002] In daily mine excavation, it is often necessary to mark both the centerline and the waistline of the roadway. The traditional approach is to equip the underground working face with two laser devices, one for indicating direction and the other for indicating slope.

[0003] This traditional method, which relies on two laser instruments to separately mark the center line and waistline, has the following shortcomings in practical applications: 1. High cost: Waste of human and material resources. Two laser devices require the installation of two combination poles, which requires 3-4 people to work together to install and debug, which is time-consuming and labor-intensive.

[0004] 2. Low equipment integration: The equipment occupies a large space and is easily restricted by the working face space conditions; due to the influence of the underground site conditions, the waistline marking position is limited and can only be marked above the unit and below the ventilation duct, which limits the installation position of the laser equipment, makes it difficult to align the laser equipment with the center waistline, and makes it even more difficult to install two laser equipment.

[0005] 3. Low work efficiency and accuracy: In the opening section of the roadway, the waistline cannot be reliably marked because the roadway sidewalls have not yet formed; due to the limitations of the working face, laser obstruction often occurs, affecting the roadway forming or slope construction during the tunneling process and causing engineering quality issues; the traditional process requires marking the waistline on both sides of the roadway first, stringing up the line, and then aligning the laser with the line before it can be used. The laser pointing is affected by the marked position of the waistline, resulting in low work efficiency and accuracy. Utility Model Content

[0006] The purpose of this invention is to provide an integrated device for centerline and waistline laser guidance to solve the technical problems of low equipment integration, low working efficiency and accuracy, and high cost.

[0007] This utility model provides an integrated laser guiding device for centerline and waistline, comprising: a laser emitter for emitting a laser beam, the laser beam being used to simultaneously indicate the centerline and waistline; an angle setter connected to the laser emitter and used to set the emission angle of the laser beam emitted by the laser emitter; and a horizontal indicator mounted on the angle setter and used to indicate the horizontal reference of the laser beam.

[0008] During operation, the integrated laser guidance device for the centerline and waistline is stably mounted on a dedicated bracket above the tunnel. The laser emitter is switched on, and the level indicator is kept horizontal at all times to establish a reliable horizontal reference for the laser emitter's emission angle. Based on the tunnel's designed slope, the angle setter is precisely rotated to the required angle value. The laser emitter, fixedly connected to the angle setter, rotates synchronously by the same angle, pointing the laser beam at the required inclination angle within the vertical plane of the tunnel's designed slope. Through fine adjustments, the laser beam emitted by the emitter passes through 3 to 4 centerline ropes pre-stretched within the tunnel, ensuring that the laser beam perfectly coincides with the tunnel's centerline on the horizontal plane. Finally, the calibrated laser beam forms a clear and stable spot on the excavation face. This spot provides two guidelines: its horizontal position indicates the tunnel's designed centerline, controlling lateral deviations in the excavation direction; its vertical position corresponds to the waistline of the tunnel's designed slope, providing a direct, real-time reference for tunnel slope construction.

[0009] Optionally, the level indicator includes a tubular spirit level, one end of which is hinged to the rotation center axis of the angle setter, and the other end of which points to the scale of the angle setter.

[0010] Optionally, the level indicator further includes a pointer portion, one end of which is connected to the other end (free end) of the tubular spirit level, and the other end points to the scale. The length direction of the tubular spirit level is parallel to or coincides with the length direction of the pointer portion, and the center line of the length direction of the pointer portion passes through the rotation center axis of the angle setter (i.e., the center of the angle setter), so that when indicating a certain scale, the center line of the length direction of the pointer portion coincides with the corresponding radius direction, ensuring the accuracy of the indicated scale.

[0011] Optionally, the level indicator includes a tubular bubble and a pointer. One end of the pointer is hinged to the rotation center axis of the angle setter, and the other end points to the scale of the angle setter. The tubular bubble is disposed on the pointer, and the length direction of the tubular bubble is parallel to or coincides with the length direction of the pointer.

[0012] Optionally, the angle setter is detachably connected to the laser emitter.

[0013] Optionally, the laser emitter is a laser pointer.

[0014] Optionally, the angle setter is a slope gauge.

[0015] The beneficial effects of this utility model include: This utility model provides an integrated laser-guided centerline and waistline indicator. Firstly, the integrated device boasts high integration, a small footprint, and minimal limitations on installation location due to working face space constraints. Even in complex or unsupported opening conditions, it effectively guides tunneling production and is suitable for centerline and waistline indication in various roadways. Secondly, installation is easy, requiring only 1-2 people for installation and debugging, saving significant manpower and material resources and reducing costs. Thirdly, the positional relationship between the angle setter and the level indicator can be directly adjusted, ensuring the vertical position of the laser beam emitted by the laser emitter corresponds to the waistline of the roadway's designed slope, eliminating the need for additional waistline rope installation, resulting in high work efficiency and accuracy.

[0025] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] This application provides an integrated device for centerline and waistline laser guidance, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, it includes: Laser emitter 1 is used to emit a laser beam, which is used to synchronously indicate the centerline and waistline; Angle setter 2 is connected to the laser emitter 1 and is used to set the emission angle of the laser beam emitted by the laser emitter 1; A horizontal indicator 7 is mounted on the angle setter 2 and is used to indicate the horizontal reference of the laser beam.

[0027] In this embodiment, the integrated centerline and waistline laser guidance device has a high degree of integration, occupies little space, and its installation location is less restricted by the working face space conditions. Even in complex or unsupported opening conditions, it can effectively guide the tunneling production at the working face, suitable for indicating the centerline and waistline of roadways under various conditions. Secondly, installation is easy, requiring only 1-2 people to complete the installation and debugging, saving significant manpower and material resources, and reducing costs. Thirdly, the operator can directly adjust the positional relationship between the angle setter and the level indicator, ensuring that the vertical position of the laser beam emitted by the laser emitter corresponds to the waistline of the roadway's designed slope, eliminating the need for additional waistline rope installation, resulting in high work efficiency and accuracy.

[0028] In one specific embodiment, reference Figure 3 , Figure 4 The level indicator 7 is a tubular bubble level 3, which is hinged at one end to the rotation center axis of the angle setter 2 in the longitudinal direction, and the other end points to the scale of the angle setter 2.

[0029] Specifically, when the operator rotates the angle setter 2 to adjust the laser emission angle, such as Figure 3 , Figure 4 Since one end of the tube level 3 is hinged to the rotation center axis of the angle setter 2, its whole does not rotate with the angle setter 2, so that the bubble of the tube level 3 is always centered. At this time, the operator can directly read the tilt angle of the current laser beam relative to the horizontal plane by observing the position of the free end of the tube level 3 on the dial.

[0030] In one specific embodiment, reference Figure 5 Figure 6The level indicator 7 includes a tubular bubble level 3 and a pointer 6. One end of the tubular bubble level 3 is hinged to the rotation center axis of the angle setter 2 along its length, and the other end points to the scale of the angle setter 2. One end of the pointer 6 is connected to the other end of the tubular bubble level 3, and the other end points to the scale. The length direction of the tubular bubble level 3 is parallel to or coincides with the length direction of the pointer 6, and the center line of the length direction of the pointer 6 passes through the rotation center axis of the angle setter 2. When the slope is zero degrees, the indicating end of the pointer 6 points to the 90 degree mark on the scale.

[0031] In one specific embodiment, reference Figure 7 , Figure 8 The level indicator 7 includes a tubular bubble level 3 and a pointer part 6; one end of the pointer part 6 is hinged to the rotation center axis of the angle setter 2, and the other end points to the scale of the angle setter 2. The tubular bubble level 3 is disposed on the pointer part 6. The length direction of the tubular bubble level 3 is parallel to or coincides with the length direction of the pointer part 6. When the slope is zero degrees, the indicating end of the pointer part 6 points to the 90 degree mark on the scale.

[0032] Specifically, when the operator rotates the angle setter 2 to the target slope value, the other end (tip) of the pointer directly indicates the corresponding angle value on the scale. The operator can directly and accurately read the scale value without moving their line of sight. The whole process is intuitive and efficient, effectively eliminating visual errors, thereby significantly improving the accuracy of slope setting and operation speed.

[0033] In one specific embodiment, the angle setter 2 is detachably connected to the laser emitter 1. This detachable connection allows for rapid disassembly and replacement in case of a malfunction in either the angle setter 2 or the laser emitter 1, significantly reducing on-site troubleshooting time and improving equipment availability.

[0034] In one specific embodiment, the laser emitter 1 is a laser pointer.

[0035] In one specific embodiment, the angle setter 2 is a slope gauge.

[0036] Specifically, such as Figure 2As shown, during operation, the integrated laser guidance device for the centerline and waistline is stably installed on a dedicated bracket above the roadway. The laser emitter 1 is switched on, and the level indicator 7 is kept horizontal at all times, thus establishing a reliable horizontal reference for the laser emitter 1's emission angle. Based on the roadway's designed slope, the angle setter 2 is precisely rotated to the required angle value. The laser emitter 1, fixedly connected to the angle setter 2, rotates synchronously by the same angle, pointing the laser beam at the required inclination angle in the vertical plane of the roadway's designed slope. Through fine adjustments, the laser beam emitted by the laser emitter 1 simultaneously passes through 3 to 4 centerline ropes pre-stretched within the roadway, ensuring that the laser beam and the roadway centerline are completely aligned horizontally. Finally, the calibrated laser beam forms a clear and stable spot on the excavation face. This spot provides two guidelines: its horizontal position indicates the roadway's designed centerline, controlling lateral deviations in the excavation direction; its vertical position corresponds to the waistline of the roadway's designed slope, providing a direct, real-time reference for roadway slope construction.
