Description

Technical Field

[0001] The utility model relates to the technical field of mine monitoring, in particular to a mine ventilation monitoring device. Background Technique

[0002] The mine ventilation monitoring system is one of the important systems in the mine. The coal mine requires "determining the production according to the ventilation", which can show the importance of the ventilation monitoring system. When the mine is being mined, generally, a monitoring device is used to monitor the ventilation state in the mine to ensure the safety during mining.

[0003] In the Chinese patent with the publication number CN217951749U, a mine ventilation monitoring device is disclosed. By rotating the threaded rod, the threaded rod drives the brake plate to limit the wheel, which can make the device more stable during use and solve the problem that it is inconvenient to limit the wheel of the existing mine ventilation monitoring device during use. However, in actual use of the above monitoring device, generally, the brake plate abuts against the wheel. However, when the wheel moves in the mine, it is easy to adhere to mud, so that the brake plate and the wheel cannot be tightly abutted, resulting in the situation that the wheel will still be pushed after stopping, thus reducing the stability of the monitoring device and affecting the detection of the mine by the monitoring device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a mine ventilation monitoring device. Through the setting of the limiting component, it can realize firm limitation of the wheel, so that the monitoring component can stably monitor the ventilation in the mine, thus solving the problem that the existing wheel is easy to adsorb mud when moving in the mine, resulting in the situation that the brake plate and the wheel cannot be tightly abutted, and the wheel will still be pushed after stopping, greatly improving the stability of the monitoring device and facilitating the accurate detection of the mine by the monitoring device, so as to solve the above deficiencies in the technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solution: A mine ventilation monitoring device, comprising:

Each limiting component includes a limiting disc fixed on one side of the wheel and a plurality of insertion slots opened on one side of the limiting disc. A plug post is inserted on the base, and one end of the plug post penetrates into the installation cavity and is inserted into the insertion slot. An adjusting component for driving the two plug posts to move in a guiding manner is provided on the base.

[0008] Preferably, the adjusting assembly includes a mounting bracket installed on the base and two guiding grooves formed on one side of the mounting bracket for two plugging columns to slide into. A first push plate and a second push plate are installed on one side of the mounting bracket, and one ends of the two first push plates are inserted into the two guiding grooves and fixedly connected to one ends of the two plugging columns. An elastic component for supporting the plugging columns is arranged in the guiding grooves; through the arrangement of the mounting bracket, it can guide the movement of the plugging columns during movement, so that the plugging columns can be more accurately plugged and fixed with one of the plugging slots, thereby limiting the wheels in the installation cavity and preventing the base from being pushed, facilitating the stable monitoring of the ventilation situation in the mine by the monitoring component.

[0009] Preferably, the elastic component includes a positioning ring fixed in the guiding groove and a pulling ring sleeved outside the plugging column, and the positioning ring is sleeved outside the plugging column. A spring is connected between the positioning ring and the guiding groove; through the arrangement of the spring, it can provide additional stability to the plugging column to ensure a firm connection between the plugging column and the plugging slot.

[0024] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0025] The present utility model provides a mine ventilation monitoring device as Figure 1 shown, including:

[0026] Base 1, on which a monitoring component 11 is installed. Four installation cavities 12 are opened at the bottom end of the base 1, and a rollable wheel 13 is installed in each installation cavity 12; the structure and principle of the monitoring component 11 are both prior arts, and specifically, reference can be made to the comparative document (publication number: CN217951749U, patent name: A mine ventilation monitoring device), which will not be elaborated here;

[0027] A plurality of limiting components 2, used to firmly fix the wheels 13. Each limiting component 2 includes a limiting disc 21 fixed on one side of the wheel 13 and a plurality of insertion slots 23 opened on one side of the limiting disc 21. Insertion columns 22 are inserted on the base 1, and one end of the insertion column 22 penetrates into the installation cavity 12 and is inserted into the insertion slot 23. An adjusting component for driving the two insertion columns 22 to move in a guiding manner is provided on the base 1; the adjusting component includes an installation frame 29 installed on the base 1 and two guiding slots 24 opened on one side of the installation frame 29 for the two insertion columns 22 to slide into. A first push plate 28 and a second push plate are installed on one side of the installation frame 29, and one end of each of the two first push plates 28 is inserted into the two guiding slots 24 and fixedly connected to one end of the two insertion columns 22. An elastic component for supporting the insertion column 22 is provided in the guiding slot 24; the elastic component includes a positioning ring 25 fixed in the guiding slot 24 and a pulling ring 27 sleeved outside the insertion column 22, and the positioning ring 25 is sleeved outside the insertion column 22. A spring 26 is connected between the positioning ring 25 and the guiding slot 24; a stabilizing component 3 for fixing the first push plate 28 to the second push plate is provided on the first push plate 28. The stabilizing component 3 includes a connecting plate 31 hinged on one side of the first push plate 28 and a clamping cavity 32 opened on one side of the second push plate. A torsion slot 33 for the second push plate to insert is opened on one side of the connecting plate 31, and a clamping block corresponding to the clamping cavity 32 is fixed in the torsion slot 33, and the clamping block is clamped and fixed with the clamping cavity 32.

[0028] As can be seen from the above, during use, the user first pushes the base 1 to move the device along the mine. Then, the wheel 13 rolls along the installation cavity 12 and the mine floor, driving the monitoring component 11 to move along the mine, enabling the monitoring component 11 to monitor the ventilation condition in the mine. Secondly, when it is necessary to stabilize the monitoring component 11, the user pushes the first push plate 28 to move along the guiding groove 24. Then, the clamping block is pulled out along the clamping cavity 32, causing the second push plate to lose the clamping effect in the torsion groove 33, and the distance between the second push plate and the torsion groove 33 is adjusted. At the same time, the connecting plate 31 is pushed to rotate along one side of the first push plate 28, disengaging the second push plate from the torsion groove 33, thus releasing the limit between the first push plate 28 and the second push plate. However, the spring 26 is tightened and a reset thrust is generated, providing a pulling force on the pull ring 27 towards the positioning ring 25. As the pull ring 27 moves along the guiding groove 24, it drives the first push plate 28 and the second push plate to move along the guiding groove 24 respectively. Then, the insertion post 22 is pushed to penetrate into the installation cavity 12 and insert into one of the insertion slots 23, enabling the wheel 13 to be firmly limited in the installation cavity 12, ensuring that the monitoring component 11 can stably monitor the ventilation in the mine, and further realizing the accurate detection of the mine by the monitoring device.

[0029] Furthermore, limit blocks are fixed on one side of the first push plate 28 and the second push plate. Limit slots corresponding to the limit blocks are formed in the guiding groove 24, and the limit slots are slidably connected to the limit blocks. Based on this, through the setting of the limit blocks, it can be ensured that the first push plate 28 and the mounting frame 29 move stably in the guiding groove 24, preventing the first push plate 28 and the mounting frame 29 from shifting during movement.

[0030] In addition, referring to Figures 1-4 as shown, a positioning component 4 for positioning and installing the mounting frame 29 is provided on the base 1. The positioning component 4 includes a mounting plate 42 fixed on one side of the mounting frame 29 and a mounting groove 41 formed on one side of the base 1, and the mounting plate 42 is fixedly connected to the mounting groove 41. Through grooves for inserting the insertion post 22 are formed on both the mounting plate 42 and the mounting groove 41. An ear plate 43 is also fixed on the mounting plate 42. An ear groove 44 corresponding to the ear plate 43 is formed in the mounting groove 41, and the ear groove 44 is slidably connected to the ear plate 43.

[0031] Through the above technical solutions:

[0032] During use, by inserting one side of the mounting plate 42 into the mounting groove 41, the mounting frame 29 then moves along the guide on the base 1, and the ear plate 43 moves synchronously along the ear groove 44 as the mounting plate 42 moves. This can prevent the mounting plate 42 from falling off during movement, enabling the mounting plate 42 to move stably. Subsequently, after the mounting plate 42 moves and abuts within the mounting groove 41, it is used to prompt the user that the mounting frame 29 can no longer move at this time, thereby fixedly connecting the mounting plate 42 and the mounting groove 41, being able to positionally connect the mounting frame 29 and the base 1, ensuring the stability of the mounting frame 29, helping to reduce the installation difficulty of the mounting frame 29, and further ensuring the normal use of the mounting frame 29.

[0033] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
