[0020] 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.
[0021] Please see Figures 1-4 In this embodiment of the utility model, a combined roadway support device includes a support frame 2, which is provided in a plurality of manners. A connecting block 13 is fixedly installed on the top side inside each support frame 2. An installation ring 10 is fixedly installed on one end of the connecting block 13. A bolt 12 is threadedly connected to the installation ring 10. A water pipe 6 is passed through the interior of each installation ring 10. The bolt 12 presses the water pipe 6 to fix it to the installation ring 10. A plurality of atomizing nozzles 19 are provided on one side of the water pipe 6. A first flange 1 is fixedly installed on the outer side of one end of the water pipe 6. A second flange 8 is fixedly installed on the outer side of the other end of the water pipe 6. Two screws 7 are passed through between the first flange 1 and the second flange 8 that are in contact with each other on two adjacent water pipes 6. Nuts 9 are symmetrically threaded on the outer side of the screws 7. The two nuts 9 are respectively tightened against the first flange 1 and the second flange 8.
[0022] A compression block 11 is rotatably mounted on one end of the bolt 12. The compression block 11 has an arc-shaped design, which increases the contact area with the water pipe 6 and improves the stability of fixing the water pipe 6.
[0023] The bottom of the support frame 2 is symmetrically fixed with a base plate 5, and the support frame 2 is fixed to the ground by the base plate 5 and expansion bolts.
[0024] The water pipe 6, which is closest to the alleyway exit, is connected to an external water source to provide water for spraying.
[0025] The front side of the support frame 2 is symmetrically fixed with slots 3. The rear side of the support frame 2 and the position corresponding to the two slots 3 are fixedly fixed with inserts 14. The two sides of the inserts 14 are provided with mounting grooves 17. A spring 15 is fixedly installed inside one side of the mounting groove 17. A limit block 16 is fixedly installed at one end of the spring 15. A limit groove 4 is provided on the slot 3 and the position corresponding to the limit block 16, so that the support frames 2 can be combined and the overall structural strength is improved. A telescopic rod 18 is provided inside the mounting groove 17 and inside the spring 15. The telescopic rod 18 includes a sleeve and a rod body. One end of the sleeve is fixedly connected to the mounting groove 17. The rod body is slidably connected inside the sleeve. One end of the rod body is fixedly connected to the limit block 16. The inserts 14 on one of the two adjacent support frames 2 are inserted into the slots 3 on the other support frame 2. The limit blocks 16 on one of the two adjacent support frames 2 pass through the limit grooves 4 on the other support frame 2.
[0026] The working principle of this utility model is as follows:
[0027] In use, a single support frame 2 is fixed to the interior top side of the tunnel and the ground via a base plate 5. Pressing the limiting block 16 causes it to compress the spring 15 and retract into the mounting groove 17. Then, the insert block 14 on another support frame 2 is inserted into the slot 3 on the previous support frame 2. During insertion, the limiting block 16 is restrained by the inner wall of the slot 3 and slides against it until it reaches the position corresponding to the limiting groove 4. At this point, the spring 15's reset action causes the end of the telescopic rod 18 to extend out of the cylinder and the limiting block 16 to pass through the limiting groove 4, thus achieving the combination of two adjacent support frames 2. After the support frame assembly is installed, the flexible water pipe 6 is passed through the mounting ring 10 on the support frame 2. The bolt 12 is rotated, and the bolt 12 drives the compression block 11 to compress and fix the water pipe 6. Adjacent water pipes 6 are fixed together by the first flange 1 and the second flange 8. The fixing method is to connect the two flanges together, pass two screws 7 through the two flanges, and tighten two nuts 9 on the outside of the screws 7 so that the nuts 9 clamp the two flanges, thereby clamping the water pipe 6. The water pipe 6 is connected to the external water source, and water will be sprayed from the atomizing nozzle 19, thereby achieving dust suppression inside the tunnel. When a water pipe 6 is damaged, the fixing of the water pipe 6 to other water pipes 6 is removed, and it can be pulled out for replacement.
[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
