[0022] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0023] like Figures 1 to 4 As shown, a wind-shielding and dust-suppressing wall for a coal mine goaf in one embodiment of the utility model comprises a mounting bracket 11, a first wind-shielding and dust-suppressing board 12 and a second wind-shielding and dust-suppressing board 13, and mounting holes are provided in the first wind-shielding and dust-suppressing board 12 and the second wind-shielding and dust-suppressing board 13.

[0024] Specifically, a fixing bracket is also provided at the bottom of the mounting bracket 11, and the fixing bracket is generally pre-buried in the ground or fixed on a pre-cast concrete foundation to ensure the stability of the mounting bracket 11. The wind and dust suppression plate is fixed to the mounting bracket 11 from bottom to top in sequence through the mounting holes and fixing bolts.

[0025] The mounting bracket 11 has a slide rail 21, a slider 22 is slidably connected to the slide rail 21, and a mounting plate 23 is fixedly connected to the slider 22. The mounting plate 23 has a first fixing hole 31 matching the mounting hole, and the mounting bracket 11 below the mounting plate 23 has a second fixing hole 32 matching the first fixing hole 31.

[0026] Specifically, the wind and dust shield plate at the bottom of the mounting bracket 11 is better fixed. The wind and dust shield plate at a high position on the mounting bracket 11 needs to be fixed with the help of a ladder or a climbing rack due to the height of the operator, which is time-consuming and laborious.

[0027] When fixing the wind and dust shielding plate, the slider 22 and the mounting plate 23 are moved to the bottom of the mounting bracket 11, and a plurality of first wind and dust shielding plates 12 are fixed on the mounting plate 23. Then, the mounting plate 23 is moved upward, and the first wind and dust shielding plate 12 on the mounting plate 23 is moved above the mounting bracket 11.

[0028] Then the mounting plate 23 is supported, and a support plate or other manual support by the installer is used, and then the second wind and dust shielding plate 13 is fixed below the mounting plate 23. At this time, the second wind and dust shielding plate 13 can support the mounting plate 23, and there is no need to support the mounting plate 23. Then, other second wind and dust shielding plates 13 are fixed in sequence.

[0029] The height of the mounting bracket 11 is 3 to 4 meters. That is, the height of the wind and dust shield is also 3 to 4 meters, which can block wind and dust. It is convenient for the operator to move the first wind and dust shield 12 to the top of the mounting bracket 11 to prevent the height of the mounting bracket 11 from being too high, which makes it impossible for the operator to move the first wind and dust shield 12 to the top of the mounting bracket 11.

[0030] The height of the slider 22 and the mounting plate 23 is half of the mounting bracket 11. When the first wind and dust shielding plate 12 is fixed on the mounting plate 23, the operator can easily move the first wind and dust shielding plate 12 to the top of the middle position of the mounting bracket 11.

[0031] The slide rail 21 is a T-shaped groove, and the slider 22 is a T-shaped block. The stability of the slider 22 when sliding in the slide rail 21 is ensured.

[0032] A handle 41 is fixedly connected to the bottom of the mounting plate 23. The handle 41 facilitates the installation personnel to move the mounting plate 23 upwards.

[0033] A protective sleeve 42 is provided on the handle 41. The protective sleeve 42 is a rubber sleeve, which can increase the comfort of the installer when pushing the handle 41.

[0034] The mounting bracket 11 is provided with a limit slot, in which a pin 51 is arranged. The pin 51 can be inserted into the limit slot, and one end of the pin 51 can extend into the slide rail 21 to support the slider 22 and prevent the mounting plate 23 from moving downward.

[0035] A spring 52 is fixedly connected between the pin shaft 51 and the mounting bracket 11, and a buffer portion 53 is provided at the front end of the pin shaft 51. The buffer portion 53 is an inclined chamfer, and when the slider 22 moves upward, the pin shaft 51 can be pushed outward along the buffer portion 53. When the slider 22 completely passes through the pin shaft 51, the pin shaft 51 can automatically pop out under the action of the spring 52 to support the slider 22. It is convenient to fix the second wind and dust suppression plate 13 located below the mounting bracket 11.

[0036] The bottom wall of the slide rail 21 is fixedly connected with a support leg 61. The slider 22 moves downward to the top of the support leg 61, and the support leg 61 can prevent the slider 22 from driving the mounting plate 23 to move to a position close to the ground. In this way, when the first wind and dust shielding plate 12 is fixed on the mounting plate 23, it is inconvenient to move the first wind and dust shielding plate 12 upward.

[0037] The height of the support legs 61 is 10 to 20 centimeters, leaving enough space for the installer to move the first wind and dust suppression board 12 upwards.

[0038] When using, refer to Figure 1 to Figure 4As shown, when installing the wind and dust shielding plate, the pin shaft 51 can be pulled outward, and the pin shaft 51 no longer supports the slider 22, and the slider 22 drives the mounting plate 23 to move downward along the slide rail 21 to the top of the support leg 61. At this time, the mounting plate 23 is located at the bottom position of the mounting bracket 11, and the installer fixes the first wind and dust shielding plate 12 on the mounting plate 23.

[0039] Then, the mounting plate 23 is moved upward by the handle 41, and the mounting plate 23 drives the slider 22 and the first wind and dust shielding plate 12 fixed on the mounting plate 23 to move upward. When the bottom end surface of the slider 22 moves to the top of the pin 51, the pin 51 pops up under the action of the spring 52 to support the slider 22, and the installation of the first wind and dust shielding plate 12 is completed. At this time, the first wind and dust shielding plate 12 is located at a high position on the mounting bracket 11. Then, the second wind and dust shielding plate 13 located at the bottom of the mounting bracket 11 is installed.

[0040] Compared with the prior art, the utility model provides a wind-proof and dust-suppressing wall for coal mine goafs. When installing the wind-proof and dust-suppressing panels at heights, there is no need to rely on ladders or set up climbing frames, which reduces the installation time and is less likely to cause high-altitude safety accidents.

[0041] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0042] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
