Description

Technical Field

[0001] This utility model relates to the field of tunnel positioning support technology, and in particular to an adjustable support for a mine tunnel positioning instrument. Background Technology

[0002] Mining tunnel positioning devices are specialized instruments installed in mining tunnels, such as those in coal mines, to determine the real-time location of personnel and equipment and monitor their movement. By integrating technologies such as RFID, UWB, and inertial navigation, they can accurately acquire the coordinates of targets in the three-dimensional space of the tunnel. They also have environmental data acquisition capabilities, enabling simultaneous monitoring of parameters such as methane concentration, temperature, and humidity within the tunnel, thus providing safety assurance for underground operations.

[0003] For example, patent application number CN202320726022.0 discloses a stable underground base station positioning server, including a server body, a battery, a motherboard, a signal transmitting chip, a signal receiving chip, and a positioning chip. A fixing plate is fixedly connected to the server body, and a positioning rod is slidably connected inside the fixing plate. This server is installed on the ground using threaded rods, connecting plates, and positioning rods. In some scenarios, workers will hang the positioning device on the side of the tunnel wall. The size of the bracket structure used to hang the positioning device is often fixed. Therefore, when hanging larger or smaller positioning devices, a mismatch between the positioning device and the bracket installation occurs, and the bracket structure cannot provide stable support for the positioning device, affecting subsequent use.

[0025] A slot 13 is provided at the end of the support arm 8 away from the back plate 1. An adjusting arm 4 is provided in the slot 13. One end of the adjusting arm 4 is slidably connected to the slot 13. A first positioning member for fixing the adjusting arm 4 is provided on the outside of the support arm 8.

[0026] Fix the back plate 1 to the side wall of the tunnel, place the positioning device that needs to be fixed on the two support arms 8, the support arms 8 support the positioning device, release the first positioning component from the fixing of the adjusting arm 4, the adjusting arm 4 can be pulled out from the slot 13, increase the support length of the support arm 8, and ensure that the adjusting bracket can place positioning devices of different widths.

[0027] The other end of the adjusting arm 4 is provided with a front baffle 11, which is fixedly installed on the upper end of the adjusting arm 4. A movable sleeve 5 is sleeved on the outside of the front baffle 11, and the movable sleeve 5 is slidably connected to the front baffle 11. A second positioning member for fixing the movable sleeve 5 is provided on the outside of the movable sleeve 5. A pressure plate 6 is provided on the upper end of the movable sleeve 5, and the pressure plate 6 is fixedly installed on the side of the movable sleeve 5 near the back plate 1.

[0028] The adjusting arm 4 and the movable sleeve 5 can limit and protect the positioning device from the front. After the second positioning component is released from fixing the movable sleeve 5, the movable sleeve 5 can be pulled up and down to adjust the height of the pressure plate 6. After the pressure plate 6 falls, it will press on the top of the positioning device, further improving the stability of the positioning device and realizing the fixing of positioning devices at different heights.

[0029] Regarding the first positioning component:

[0030] The first positioning component includes a second positioning bolt 14, which is mounted on the lower end of the support arm 8. A plurality of second positioning holes 15 are provided on the outer side of the adjusting arm 4. The second positioning holes 15 are evenly arranged along the length of the adjusting arm 4, and the second positioning holes 15 are threadedly connected to the second positioning bolt 14.

[0031] Rotate the second positioning bolt 14 to unscrew it from the second positioning hole 15 on the outside of the adjusting arm 4, thus releasing the fixed state between the support arm 8 and the adjusting arm 4. Adjust the horizontal position of the adjusting arm 4 by screwing the second positioning bolt 14 into the corresponding second positioning hole 15, thus completing the horizontal position adjustment of the adjusting arm 4.

[0032] Regarding the second positioning component:

[0033] The second positioning component includes a first positioning bolt 10, which is mounted on the side of the movable sleeve 5 away from the back plate 1. A plurality of first positioning holes 12 are provided on the outer side of the front baffle 11. Each first positioning hole 12 is evenly arranged along the height direction of the front baffle 11, and the first positioning holes 12 are threadedly connected to the first positioning bolt 10.

[0034] Rotate the first positioning bolt 10 to unscrew it from the first positioning hole 12 on the outside of the front baffle 11, thus releasing the fixed state between the movable sleeve 5 and the front baffle 11. Adjust the set height of the movable sleeve 5 and screw the first positioning bolt 10 into the corresponding first positioning hole 12 to complete the height adjustment of the movable sleeve 5.

[0035] To improve the stability of the adjusting arm 4 during sliding, limit grooves are provided on the left and right sides of the adjusting arm 4. A guide rib 17 is provided inside the slot 13. The guide rib 17 is fixedly connected to the support arm 8 and slidably connected to the limit groove.

[0036] After the adjusting arm 4 is pushed into the slot 13, the guide rib 17 on the inner side of the slot 13 will be engaged in the limiting grooves opened on the left and right sides of the adjusting arm 4. The guide rib 17 guides the adjusting arm 4 from the left and right sides by cooperating with the limiting grooves.

[0037] It is worth explaining in detail that a bolt plate 16 is provided on one side of the adjusting arm 4, and the bolt plate 16 is fixedly connected to the adjusting arm 4. The bolt plate 16 has mounting bolt holes. The positioning device is fixed to the support arm 8 by bolting.

[0038] The back panel 1 has multiple bolt lugs 3 on its outer side, which are fixedly connected to the back panel 1. The bolt lugs 3 have mounting holes. Similarly, the back panel 1 is also fixed to the external wall or frame by bolting.

[0039] The back plate 1 has a rubber pad 2 on its front side, and the rubber pad 2 is fixedly connected to the back plate 1. The back plate 1 supports the positioning instrument from the back. The rubber pad 2 between the back plate 1 and the positioning instrument will contact the instrument shell first, and the rubber pad 2 can play a cushioning role.

[0040] Similarly, a rubber pad 9 is provided on the lower end face of the pressure plate 6, and the rubber pad 9 is fixedly connected to the pressure plate 6. When the pressure plate 6 presses on the top of the positioning device, the rubber pad 9 fixed to the lower end of the pressure plate 6 will contact the positioning device first, dispersing the pressure at the contact point between the positioning device and the rubber pad 9, protecting the positioning device, and also playing a shock-resistant role.

[0041] To improve the structural strength of the support arm 8, a reinforcing rib 7 is provided at the angle between the support arm 8 and the back plate 1, and the reinforcing rib 7 is fixedly installed at the lower end of the support arm 8.

[0042] How this application works:

[0043] The backplate 1 is fixed to the side wall of the tunnel. The positioning device to be fixed is placed on the two support arms 8, which support the positioning device. The first positioning component is released from fixing the adjusting arm 4, allowing the adjusting arm 4 to be pulled out from the slot 13, increasing the support length of the support arm 8 and ensuring that the adjusting bracket can support positioning devices of different widths. The adjusting arm 4 and the movable sleeve 5 limit and protect the positioning device from the front. After the second positioning component is released from fixing the movable sleeve 5, the movable sleeve 5 is pulled up and down to adjust the height of the pressure plate 6. After the pressure plate 6 falls, it will press on the top of the positioning device, further improving the stability of the positioning device and achieving the fixing of positioning devices of different heights.
