Description

Technical Field

[0001] This utility model relates to the field of support construction technology, specifically to an auxiliary directional device for tunneling support. Background Technology

[0002] Tunneling support is a series of support measures taken during underground mining to prevent damage to the surrounding rock of tunnels and ensure normal production and safety. Tunneling support is an important part of tunneling and support operations, aiming to prevent the surrounding rock of tunnels from becoming unstable due to fracturing, weathering or other reasons, thereby ensuring normal mine production and the safety of workers.

[0003] In existing technologies, during coal cutting and support operations at the tunneling face, a laser pointer is used to determine the direction of the roadway's advance, commonly known as the "roadway centerline." However, during anchor mesh support or canopy support operations, the laser pointer can only determine the left and right positions of the steel reinforcement top support beams or I-beams, not their positions at the front and rear of the roadway. This can lead to tilting. During roadway support, the top steel strip must be parallel to the roadway's advance direction and perpendicular to the roadway walls. In actual tunneling, on-site workers determine the steel strip position through on-site measurement or observation. Due to uneven roadway roofs and incorrect observation methods, installation is often based on experience, resulting in tilting of the top steel reinforcement support beams (i.e., the steel strip stepping), improper beam installation, unstable roadway support, and the need for reinforcement in certain areas, leading to the consumption of support materials.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Please see Figures 1-4 This utility model discloses a tunneling support auxiliary orientation device, including a crossbar 1. A first fixing mechanism 2 is installed on the rear side of the crossbar 1. A second fixing mechanism 3 is provided on the crossbar 1. A circular sleeve 4 is fixedly installed on the lower surface of the second fixing mechanism 3. An adjusting mechanism 5 is installed inside the lower surface of the circular sleeve 4. An installation sleeve 6 is fixedly installed on the lower surface of the adjusting mechanism 5. A laser pointer 7 is provided inside the installation sleeve 6. First fastening bolts 8 are threaded on the front and rear sides of the installation sleeve 6, and the front and rear first fastening bolts 8 lock and fix the laser pointer 7. A beam splitting mechanism 9 is provided on the left side of the laser pointer 7. A calibration mechanism 10 is provided on the left side of the beam splitting mechanism 9.

[0021] Specifically, the first fixing mechanism 2 includes a sliding sleeve 201 and a second fastening bolt 202. The sliding sleeve 201 is fixedly installed on the rear side of the crossbar 1, and the second fastening bolt 202 is threaded on the left and right side walls of the sliding sleeve 201.

[0022] In this embodiment, the sliding sleeve 201 is fitted onto the reinforcing steel bar at the top of the tunnel, and the sliding sleeve 201 is installed onto the reinforcing steel bar by the second fastening bolt 202, so as to achieve the effect of adjusting the height of the laser pointer 7.

[0023] Specifically, the second fixing mechanism 3 is the same as the first fixing mechanism 2, and the second fixing mechanism 3 is the first fixing mechanism 2 rotated by ninety degrees.

[0024] In this embodiment, the second fixing mechanism 3 can move back and forth and rotate on the crossbar 1 to achieve the effect of adjusting the front and back position and tilt angle of the laser pointer 7.

[0025] Specifically, the adjustment mechanism 5 includes a cylinder 501, an annular groove 502, and a third fastening bolt 503. The cylinder 501 is inserted into the sleeve 4. The annular groove 502 is formed on the outer surface of the cylinder 501. The third fastening bolt 503 is threaded on the front and rear side walls of the sleeve 4 corresponding to the annular groove 502, and the front and rear third fastening bolts 503 lock and fix the cylinder 501.

[0026] In this embodiment, the third fastening bolt 503 is loosened, allowing the cylinder 501 to rotate within the sleeve 4. After the laser pointer 7 is adjusted, the cylinder 501 and the sleeve 4 can be locked and fixed by the front and rear third fastening bolts 503, achieving the effect of adjusting the direction of the laser pointer 7. The cylinder 501 will not detach from the sleeve 4 when the annular groove 502 is loosened.

[0027] Specifically, the beam splitting mechanism 9 includes a beam splitting prism 901, a rubber sleeve 902, and a circular hole 903. The outer surface of the beam splitting prism 901 is fitted with a rubber sleeve 902, and a circular hole 903 is provided at the center of the four sides of the rubber sleeve 902.

[0028] In this embodiment, the beam splitter prism 901 splits the light emitted by the laser pointer 7 into two perpendicular beams. One beam follows the same trajectory as the original beam from the laser pointer 7, while the other beam is perpendicular to the original beam and points towards the roadside. The rubber sleeve 902 protects the beam splitter prism 901 from impact damage, and the circular hole 903 meets the light illumination requirements.

[0029] Specifically, the calibration mechanism 10 includes a cone body 101, a groove 102, a pull rope 103, and a mounting plate 104. The upper surface of the cone body 101 has a groove 102. The pull rope 103 is fixedly installed on the lower side wall of the groove 102. The upper end of the pull rope 103 is fixedly installed on the mounting plate 104. The mounting plate 104 is threaded into the groove 102.

[0030] In this embodiment, the mounting plate 104 is installed on the top of the roadway, and the pull rope 103 is used to install the hoisting cone body 101. At the same time, the hoisting cone body 101 calibrates the light on the original light trajectory of the laser pointer 7.

[0031] In use, the sliding sleeve 201 in the first fixing mechanism 2 is fitted onto the reinforcing steel bar at the top of the tunnel. The sliding sleeve 201 is then installed onto the reinforcing steel bar using the second fastening bolt 202, allowing the crossbar 1 to move up and down. The second fixing mechanism 3 can move back and forth and rotate on the crossbar 1, driving the circular sleeve 4 to move back and forth and rotate. Then, the third fastening bolt 503 in the adjusting mechanism 5 is loosened, allowing the cylinder 501 to rotate within the circular sleeve 4. After the laser pointer 7 is adjusted, the cylinder 501 and the circular sleeve 4 are locked and fixed using the front and rear third fastening bolts 503, achieving the effect of adjusting the installation height, front and rear position, tilt angle, and orientation of the laser pointer 7. After installing the laser pointer 7, the mounting plate 104 in the calibration mechanism 10 is installed on the top of the tunnel, and the pull rope 103 is used to install the main body 101 of the lifting cone. The body 101 is located on the original light trajectory of the laser pointer 7. The light emitted by the laser pointer 7 illuminates the beam splitting prism 901 in the beam splitting mechanism 9. The beam splitting prism 901 splits the light emitted by the laser pointer 7 into two perpendicular beams. The first beam follows the same trajectory as the original light from the laser pointer 7, while the second beam is perpendicular to the original beam and points towards the roadway side. In actual installation, to ensure that the first laser beam refracted by the beam splitting prism 901 is aligned with the original laser beam, calibration is performed using the main body 101. When installing the top steel reinforcement support beam or I-beam, ensuring that the top steel reinforcement support beam or I-beam is parallel to the second beam indicates correct installation. This prevents the steel belt from stepping, improves the stability of the roadway support, and avoids the need for reinforcement in roadway areas due to improper beam installation, indirectly reducing the consumption of support materials.

[0032] In summary, this tunneling support auxiliary orientation device can ensure the correct installation of the steel reinforcement support beams or I-beams on the tunnel roof, prevent the steel strip from stepping, improve the stability of the tunnel support, avoid the need for reinforcement in tunnel areas due to improper beam installation, and indirectly reduce the consumption of support materials.
