Description

Technical Field

[0001] This utility model relates to the technical field of dust monitoring instrument mounting brackets, specifically a dust monitoring instrument mounting bracket for large-section tunnel blasting. Background Technology

[0002] Considering the needs of tunnel safety and construction progress, and in accordance with the blasting regulations that the total time for each section of the electric detonator in a high-gas tunnel coal mine should not exceed 130ms, cross-sectional excavation and blasting will be carried out on the tunnel face. During the blasting process, in order to reduce environmental pollution, it is necessary to monitor dust and air. Therefore, a dust monitor is required. However, due to the uneven terrain, the monitor needs to be installed using a mounting frame.

[0003] Chinese Utility Model Patent Publication No. CN219823203U discloses an instrument mounting bracket, comprising a combined square frame and a docking slot. The top surface of the combined square frame has the docking slot, and a support roller is installed inside the frame. A support rod is provided at the bottom end of the frame, and the support rod has a docking hole. A bottom is fixedly installed at the bottom end of the support rod, and a positioning hole is provided at the middle of the bottom. A first adjusting shaft and a second adjusting shaft are installed above the bottom. A connecting rod is installed at the center of the first adjusting shaft, and an adjusting hole is provided at the center of the second adjusting shaft, with the adjusting hole connected to the connecting rod. This instrument mounting bracket allows for adjustment of the distance between the ring and the positioning rod through rotational adjustment between the first and second adjusting shafts. Subsequently, the positioning rod engages with the positioning hole to precisely stabilize the distance between the bottoms, preventing misalignment.

[0004] While the aforementioned mounting bracket can facilitate users in adjusting the installation spacing to avoid misalignment during use, it lacks a mechanism for folding, resulting in a large space occupation during transportation or handling and reducing its practicality. Therefore, we propose a mounting bracket for a dust monitor used in large-section tunnel blasting. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a dust monitoring device mounting bracket for large-section tunnel blasting, thereby solving the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust monitoring device mounting frame for large-section tunnel blasting, comprising a mounting structure, connecting components, and reinforcing components. The mounting structure includes a mounting plate, a fixing hole on the top of the mounting plate, a connecting plate and a positioning block fixedly mounted on the top of the mounting plate, a mounting hole on the outer wall of the connecting plate, a positioning screw fixedly mounted on the outer wall of the positioning block, and a fastening nut threadedly connected to the outer wall of the positioning screw. The connecting assembly includes a connecting rod with a circular hole on its outer wall. Rotating rods are rotatably connected to both sides of the connecting rod. A second connecting groove is provided on the outer wall of the rotating rod. A crossbar is rotatably connected to the outer wall of the rotating rod. A positioning plate is rotatably connected to the top of the connecting rod. A first connecting groove is provided on the outer wall of the positioning plate. A top plate is fixedly mounted on the top of the positioning plate. A through hole is provided on the top of the top plate.

[0007] Through the above technical solution, the installation structure, connecting components, mounting plate, fixing holes, positioning screw, fastening nut, connecting rod, rotating rod, top plate, and through-hole structure are designed so that when the user moves or assembles the mounting frame, the connecting rod and the top plate can be folded and the rotating rod can be flipped and folded due to the rotatable connection between the connecting rod and the rotating rod. This reduces the space occupied by the mounting frame, makes it convenient for the user to transport or carry, and thus improves the practicality of the mounting frame.

[0008] Preferably, the reinforcing assembly includes a reinforcing rod that fits against the outer wall of the rotating rod. The outer wall of the reinforcing rod is provided with a second positioning screw. The outer wall of the second positioning screw is threaded with a second fastening nut. The outer wall of the reinforcing rod is fixedly fitted with a third positioning screw. The outer wall of the third positioning screw is threaded with a third fastening nut. A round rod is fixedly fitted on the side wall of the reinforcing rod away from the third positioning screw.

[0009] Through the above technical solution, by setting up a structure of reinforcing rod, positioning screw two, fastening nut two, and positioning screw three, the user can first connect the reinforcing rod to the rotating rod during assembly, then align the positioning block on the mounting plate with the connecting rod, and finally tighten the fastening nut one by inserting the positioning screw one into the round hole to fix the mounting plate and the connecting rod. This achieves the effect of reinforcing the mounting frame through the connection between the connecting plate and the reinforcing rod, thereby improving the stability of the mounting frame after installation.

[0010] Preferably, the diameter of the positioning screw is adapted to the diameter of the circular hole, and the connecting rod is fixedly connected to the mounting plate through the positioning block.

[0011] Through the above technical solution, by setting the positioning screw and the round hole structure, the user can push the mounting plate to make the positioning block align with the connecting rod during the assembly process, so that the positioning screw can be inserted into the round hole. This makes it convenient for the user to assemble the mounting bracket and improves the user's assembly efficiency.

[0012] Preferably, the diameter of the crossbar is adapted to the diameter of the connecting groove, and the rotating rod is fixedly connected to the connecting rod by a reinforcing rod.

[0013] Through the above technical solution, by setting the connecting groove and the crossbar structure, the mounting bracket can use the connecting groove to store the crossbar and position the angle of the rotating rod during the installation process, thereby achieving the effect of assembling the mounting bracket and ensuring its normal use.

[0014] Preferably, the outer wall of the fastening nut three is in close contact with the outer wall of the connecting rod, and there are two positioning screws three, both of which are symmetrically distributed along the outer wall of the round rod.

[0015] Through the above technical solution, the two positioning screws are designed to connect the reinforcing rod during use, thereby increasing the connection between the reinforcing rod and the rotating rod, and also increasing the tightness of the connection between the two, thus further improving the stability of the mounting bracket.

[0016] Preferably, the outer wall of the positioning screw three is slidably connected to the inner wall of the connecting groove two, and the rotating rod is fixedly connected to the reinforcing rod through the positioning screw three.

[0017] Through the above technical solution, the user can pull out the mounting plate and remove the reinforcing rod by unscrewing the three fastening nuts and the one fastening nut during use. This makes it easy for the user to disassemble and assemble the mounting bracket, thus ensuring that the mounting bracket is recyclable and further improving its practicality.

[0018] Preferably, the diameter of the second positioning screw is adapted to the diameter of the mounting hole, and the connecting plate is fixedly connected to the reinforcing rod through the second positioning screw.

[0019] Through the above technical solution, the connection plate, reinforcing rod, and positioning screw structure make it easy for the user to pass the positioning screw through the mounting hole after installing the mounting plate, and tighten the fixing nut to reinforce the rotating rod, thereby ensuring the stability of the dust monitor during use and further improving the practicality of the mounting bracket.

[0020] Compared with the prior art, this utility model provides a dust monitoring instrument mounting bracket for large-section tunnel blasting, which has the following beneficial effects: 1. The mounting frame for the dust monitor used in large-section tunnel blasting, through its installation structure, mounting plate, fixing holes, fastening nuts, connecting plate, positioning block, and rotating rod structure, allows the user to fold the rotating rod and rotating arm separately during transportation or handling. This effectively reduces the space occupied by the mounting frame, making it easier for the user to transport and handle, easier to carry, reducing transportation costs, and improving the practicality of the mounting frame.

[0021] 2. The mounting frame for the dust monitor used in large-section tunnel blasting, through the setting of reinforcement components, reinforcement rods, positioning screws two and three, fastening nuts two and three, allows the mounting frame to reinforce the rotating rod during use, thereby effectively reducing the probability of the rotating rod tilting or even shifting position when supporting the connecting rod, and thus improving the stability of the dust monitor after installation.

This achieves the effect of reinforcing the mounting frame by connecting the connecting plate 105 with the reinforcing rod 301, thereby improving the stability of the mounting frame after installation.

[0029] Specifically: the diameter of the positioning screw 103 is matched with the diameter of the round hole 209, and the connecting rod 201 is fixedly connected to the mounting plate 101 through the positioning block 106.

[0030] The advantage is that, through the structure of the positioning screw 103 and the round hole 209, during the assembly process, the user can push the mounting plate 101 to make the positioning block 106 align with the connecting rod 201, thereby allowing the positioning screw 103 to be inserted into the round hole 209. This facilitates the user's assembly of the mounting bracket and improves the user's assembly efficiency.

[0031] Specifically: the diameter of the crossbar 207 is matched with the diameter of the connecting groove 206, and the rotating rod 202 is fixedly connected to the connecting rod 201 through the reinforcing rod 301.

[0034] The advantage is that, through the structure of the two positioning screws 304, the mounting bracket can be used to connect the reinforcing rod 301 during use, thereby increasing the connection structure between the reinforcing rod 301 and the rotating rod 202, and also increasing the tightness of the connection structure between the two, further improving the stability of the mounting bracket.

[0035] Specifically: the outer wall of the positioning screw 304 is slidably connected to the inner wall of the connecting groove 208, and the rotating rod 202 is fixedly connected to the reinforcing rod 301 through the positioning screw 304.

[0036] The advantage is that, through the installation bracket, the user can pull out the mounting plate 101 and remove the reinforcing rod 301 by unscrewing the fastening nut 305 and fastening nut 104 during use. This makes it easy for the user to disassemble and assemble the mounting bracket, thus ensuring that the mounting bracket is recyclable and further improving its practicality.

[0037] Specifically: the diameter of the positioning screw 302 is matched with the diameter of the mounting hole 107, and the connecting plate 105 is fixedly connected to the reinforcing rod 301 through the positioning screw 302.

[0038] The advantage is that, through the structure of the connecting plate 105, the reinforcing rod 301, and the positioning screw 302, after installing the mounting plate 101, the user can easily pass the positioning screw 302 through the mounting hole 107 and tighten the fastening nut 303 to reinforce the rotating rod 202 with the reinforcing rod 301, thereby ensuring the stability of the dust monitor during use and further improving the practicality of the mounting bracket.

[0039] Working principle: When assembling or transporting the mounting bracket, the user can first fold the connecting rod 201 against the outer wall of the positioning plate 205 by folding it. Then, by flipping the rotating rod 202, the rotating rod 202 and the connecting rod 201 are folded together, thereby reducing the space occupied by the mounting bracket during transportation or handling. This makes it easier for the user to transport and carry the mounting bracket, improving its practicality. During installation, the connecting rod 201 is unfolded again, and the crossbar 207 is placed in the connecting groove 206, followed by reinforcement. Tighten the reinforcing rod 301 and the three fastening nuts 305 to fix the reinforcing rod 301 to the rotating rod 202. Then, align the positioning block 106 on the mounting plate 101 with the connecting rod 201 so that the positioning screw 103 passes through the round hole 209. At this time, the connecting plate 105 and the end of the reinforcing rod 301 away from the rotating rod 202 are tightly fitted. Pass the positioning screw 202 through the mounting hole 107 and tighten the three fastening nuts 305 and the two fastening nuts 303 respectively. Thus, the reinforcing rod 301 reinforces the rotation of the rotating rod 202, thereby improving the stability of the dust monitor during operation.
