Description
Technical Field
[0001] This utility model relates to the field of dust control net technology, specifically to a fixing device for covering bare soil with dust control net. Background Technology
[0002] With the development of the construction industry and the increasing emphasis on environmental protection, dust control has become a routine management practice, and various regions have issued standards for dust control in the construction engineering field. At present, most of the earthwork stockpiled and exposed areas at construction sites are covered with green dust-control netting, and after the netting is installed, it needs to be secured with fixing devices.
[0003] The existing fixing device places the dust net on the bare soil surface, and then inserts it into the ground through the holes on the edge of the dust net via a fixing frame. The blocking frame installed on the surface of the fixing frame fixes the dust net. However, there is a gap between the two sets of fixing frames, which makes the dust net in the gap easy to be blown away by the wind.
[0004] The aforementioned fixing device has gaps between adjacent fixing frames, which makes the edges of the dustproof net easily blown up by the wind, thus reducing the fixing effect of the device. Utility Model Content
[0005] This utility model proposes a fixing device for covering bare soil with dustproof netting, which solves the problem in the prior art that fixing frames are difficult to fix at the edges of the dustproof netting.
[0006] The technical solution of this utility model is as follows: A fixing device for covering bare soil with dustproof netting, including an installation pipe, and further comprising:
[0007] The connecting frame is installed on the outer surface of the mounting tube. A movable column is slidably connected inside the connecting frame. A fixing pin is passed through the upper surface of the connecting frame. One end of the fixing pin, which is inserted into the connecting frame, abuts against the movable column. The connecting block is installed on the lower surface of the movable column. A lower pressure plate is installed on the lower surface of the connecting block. A plug-in post is installed on the lower surface of the lower pressure plate. The connecting piece is installed on the upper surface of the lower pressure plate. A connecting shaft is rotatably connected inside the connecting piece. A fixing block is installed on the outer surface of the connecting shaft. The connecting tube is installed on the outer side of the connecting piece. The connecting shaft passes through the connecting tube. A connecting pin is passed through the outer surface of the connecting tube. One end of the connecting pin, which is inserted into the connecting tube, abuts against the connecting shaft. The connecting frame is installed on the side of the fixing block. An auxiliary rod passes through the inside of the connecting frame. An auxiliary plate is installed on the outer end of the auxiliary rod.
[0008] As a preferred embodiment of the fixing device for the bare soil covering dustproof net described in this utility model, in order to facilitate the operator to install the fixing rod, an auxiliary tube is installed on the front of the connecting frame, and the fixing rod passes through the inside of the auxiliary tube.
[0009] As a preferred embodiment of the fixing device for the bare soil covering dustproof net described in this utility model, in order to prevent the fixing rod from detaching from the auxiliary pipe during the downward movement, a blocking plate is installed at the top of the fixing rod, and an auxiliary block is slidably connected inside the fixing rod.
[0010] As a preferred embodiment of the fixing device for the bare soil covering dustproof net of this utility model, in order to better fix the dustproof net, an mounting plate is installed on the outer side of the auxiliary block, and the fixing rod passes through the interior of the mounting plate.
[0011] As a preferred embodiment of the fixing device for the bare soil covering dustproof net of the present invention, in order to make it easier for operators to lift the installation pipe, a connecting ring is installed inside the installation pipe, a support rod passes through the inside of the connecting ring, a blocking plate is installed at the top of the support rod, and both the blocking plate and the support rod pass through the installation pipe.
[0012] As a preferred embodiment of the fixing device for the bare soil covering dustproof net of this utility model, in order to facilitate the repositioning of the connecting frame after the operator loosens the installation pipe, a buffer spring is installed on the lower surface of the blocking plate, the outer surface of the support rod passes through the interior of the buffer spring, and a fixing frame is installed on the outer surface of the support rod.
[0013] The working principle and beneficial effects of this utility model are as follows:
[0014] In this invention, the movable column extends to the right along the connecting frame, and the operating auxiliary plate flips to the right along the connecting piece via the connecting shaft to contact the dustproof net. Compared with the existing technology of fixing the dustproof net at intervals, this device can reduce the gap between adjacent installation tubes, maximize the coverage of the edge area of the dustproof net, and prevent the dustproof net from being blown away by the wind due to large gaps.
[0015] In this invention, by moving the mounting plate directly below the auxiliary tube and then sliding it along the fixing rod via the auxiliary block, compared to the prior art which places a set of fixing parts at intervals, this device can fill the gaps between the mounting tubes to the maximum extent, reduce the exposed area of the dustproof net edge, and improve the fixing effect of the device.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0023] like Figures 1-4 As shown, this embodiment proposes a fixing device for covering bare soil with dustproof netting, including an installation pipe 1, a connecting frame 2, a movable column 3, a connecting block 4, a lower pressure plate 5, a fixing pin 6, a plug-in column 7, a connecting piece 8, a connecting shaft 9, a fixing block 10, a connecting pipe 11, a connecting pin 12, a connecting frame 13, an auxiliary rod 14, and an auxiliary plate 15;
[0024] like Figure 1 and Figure 4As shown, the connecting frame 2 is installed on the outer surface of the mounting tube 1. A movable column 3 is slidably connected inside the connecting frame 2. A fixing pin 6 passes through the upper surface of the connecting frame 2, with one end of the fixing pin 6 penetrating the connecting frame 2 and pressing against the movable column 3. A connecting block 4 is installed on the lower surface of the movable column 3. A lower pressure plate 5 is installed on the lower surface of the connecting block 4. The lower pressure plate 5 moves downward, causing the insertion post 7 to move downward, allowing the insertion post 7 to pass through the holes in the dustproof net and insert into the ground. The insertion post 7 is installed on the lower surface of the lower pressure plate 5, and a connecting piece 8 is installed on the upper surface of the lower pressure plate 5. A connecting shaft 9 is rotatably connected inside the connecting piece 8. A fixing block 10 is mounted on the outer surface of the connecting shaft 9. A connecting tube 11 is installed on the outer side of the connecting piece 8. The connecting shaft 9 passes through the connecting tube 11. A connecting pin 12 passes through the outer surface of the connecting tube 11. One end of the connecting pin 12, which passes through the connecting tube 11, abuts against the connecting shaft 9. A connecting frame 13 is installed on the side of the fixing block 10. An auxiliary rod 14 passes through the inside of the connecting frame 13. An auxiliary plate 15 is installed on the outer end of the auxiliary rod 14. It should be noted that the initial state of the auxiliary plate 15 is as follows: Figure 1 As shown, when the edge of the dustproof net is still exposed after the moving column 3 is fully extended, the operator will then flip the auxiliary plate 15 to the right to unfold it.
[0025] like Figure 3 As shown, an auxiliary tube 16 is installed on the front of the connecting frame 2. A fixing rod 17 runs through the inside of the auxiliary tube 16. A blocking plate 18 is installed at the top of the fixing rod 17. It should be noted that there are five sets of fixing rods 17. When the moving column 3 is not extended, the number of fixing rods 17 is not needed. After the moving column 3 extends outward, the fixing rods 17 are installed one by one to avoid affecting the normal movement of the lower pressure plate 5. An auxiliary block 20 is slidably connected inside the fixing rod 17. After the auxiliary block 20 enters the fixing rod 17 and is blocked, the position of the mounting plate 19 is moved. It should be noted that the part of the fixing rod 17 located below the mounting plate 19 and the fixing frame 25 are all inserted into the ground after installation. Therefore, the lower pressure plate 5 and the flipped auxiliary plate 15 can contact the ground and will not be suspended. The mounting plate 19 is installed on the outer side of the auxiliary block 20, and the fixing rod 17 runs through the inside of the mounting plate 19.
[0026] like Figure 2 As shown, a connecting ring 21 is installed inside the mounting tube 1, and a support rod 22 passes through the inside of the connecting ring 21. A baffle plate 23 is installed at the top of the support rod 22. By manipulating the mounting tube 1, the connecting ring 21 is moved upward, which compresses the buffer spring 24. The upward movement of the mounting tube 1 lifts the connecting frame 2 upward. In order to place the edge of the dustproof net directly below the connecting frame 2, both the baffle plate 23 and the support rod 22 are installed inside the mounting tube 1. A buffer spring 24 is installed on the lower surface of the baffle plate 23, and the outer surface of the support rod 22 passes through the interior of the buffer spring 24. A fixing bracket 25 is installed on the outer surface of the support rod 22.
[0027] In this embodiment, the auxiliary plate 15 is manipulated to insert the auxiliary rod 14 into the connecting frame 13, moving the device to the installation location. The fixing frame 25 is inserted into the ground. The mounting tube 1 is manipulated to move the connecting ring 21 upward, compressing the buffer spring 24. The connecting ring 21 moves upward along the support rod 22, and the upward movement of the mounting tube 1 moves the connecting frame 2 upward, lifting the lower pressure plate 5 upward and moving the edge of the dustproof net directly below the connecting frame 2. Depending on the dustproof net, the moving column 3 is manipulated to move to the right along the connecting frame 2. The rightward movement of the moving column 3 moves the connecting block 4 to the right, and the rightward movement of the connecting block 4 moves the lower pressure plate. Move 5 to the right, the lower pressure plate 5 moves to the right and drives the connecting piece 8 to move to the right. After the movement is complete, operate the fixing pin 6 to pass through the connecting frame 2 and press against the moving column 3. Release the mounting tube 1 so that the buffer spring 24 rebounds and drives the connecting ring 21 to move downward along the support rod 22. The downward movement of the connecting ring 21 drives the mounting tube 1 to move downward. The downward movement of the mounting tube 1 drives the connecting frame 2 to move downward. The downward movement of the connecting frame 2 drives the moving column 3 to move downward. The downward movement of the moving column 3 drives the connecting block 4 to move downward. The downward movement of the connecting block 4 drives the lower pressure plate 5 to move downward, so that the insertion post 7 passes through the dustproof net and inserts into the ground. The lower pressure plate 5 contacts the dustproof net.
[0028] Move the mounting plate 19 directly below the auxiliary tube 16, manipulate the fixing rod 17 to move downward through the auxiliary tube 16, the fixing rod 17 enters the mounting plate 19, and the auxiliary block 20 slides along the inside of the fixing rod 17. The fixing rod 17 continues to move downward and inserts into the ground.
[0029] When there are still gaps in the dustproof net, pull out the connecting pin 12, operate the auxiliary plate 15 to rotate upward 180 degrees, the auxiliary plate 15 rotates upward to drive the connecting frame 13 to rotate, the connecting frame 13 rotates to drive the fixing block 10 to rotate, the fixing block 10 rotates along the connecting piece 8 through the connecting shaft 9, so that the auxiliary plate 15 contacts the ground, operate the connecting pin 12 to pass through the connecting pipe 11 and press against the connecting shaft 9.
[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
