AI Technical Summary
Existing coal mine gas monitoring equipment is prone to delays or errors in gas concentration monitoring, mainly because the air inlet at the lower end of the gas alarm is blocked, leading to inaccurate monitoring.
A clamping component was designed, including a support leg, a mounting frame, a pull frame, a pressure plate, and an insertion post. The pull frame pulls the pressure plate to insert the insertion post into the gas detector, and the support leg raises the detector to ensure that the air inlet is fully exposed. The clamping component is securely fixed by the cooperation of a stepper motor and a drive slide frame.
Ensuring the lower part of the gas detector is fully in contact with the air avoids obstructing the air intake, thus improving monitoring accuracy and stability, and enhancing the applicability and service life of the equipment.

Abstract
Description
Technical Field
[0001] This application relates to the field of gas monitoring technology, and in particular to a coal mine gas monitoring device. Background Technology
[0002] Methane gas, also known as biogas or natural gas, is primarily composed of methane. It is a colorless, odorless, tasteless, flammable, and explosive gas. A methane explosion generates high temperatures, high pressures, and shock waves, releasing toxic gases. Methane explosions are among the most serious hazards in coal mines, characterized by their destructiveness and suddenness, often causing significant casualties and property damage. Improper handling or failure to grasp key points during the handling of methane explosions can lead to multiple explosions, escalating the accident. Therefore, monitoring methane concentrations is essential in coal mines to ensure safety.
[0003] The prior art patent document CN221418437U provides a coal mine gas monitoring device. This device solves the problem by installing clamps. When workers need to install a gas monitor, they place the gas monitor into the transport ring, control the rotation of the bevel gear to drive the rotation of the drive turntable, and move the clamps along the square convex screw towards the center to clamp and fix the gas monitor. Because multiple clamps are used, circular, hexagonal and other shaped devices can be tightly fixed. Then, the drive wheel is started so that the transport body moves by track, which can adapt to complex terrain. Workers control the transport body to go deep into the mine for monitoring, thereby improving production safety, preventing the monitor from falling, increasing the service life of the equipment, and expanding the scope of application of the equipment.
[0004] Although the existing technical solutions mentioned above can prevent the monitor from falling by using clamps, they still have the following drawbacks: the existing technology clamps and fixes the bottom of the gas alarm, but because the bottom of the gas alarm is the air inlet, the existing technology will block the air intake, which can easily cause problems such as delayed or inaccurate monitoring of gas concentration.
[0005] In view of this, we propose a coal mine gas monitoring device. Utility Model Content
[0006] 1. The technical problem to be solved.
[0007] The purpose of this application is to provide a coal mine gas monitoring device to solve the problems mentioned in the background art that easily cause delays or errors in monitoring gas concentration, and to achieve that there is no interference with gas concentration monitoring.
[0008] 2. Technical solution.
[0009] A coal mine gas monitoring device, comprising an electric tracked vehicle.
[0010] A gas detector is mounted and fixed to the top surface of an electric tracked vehicle using clamping components.
[0011] The clamping component includes a support leg that is fixedly connected to the top surface of the electric tracked vehicle. A mounting frame is fixedly connected to the upper end of the support leg. A pull frame is slidably connected to the mounting frame. A pressure plate is fixedly connected to the end of the pull frame. A plug is fixedly connected to the inner end of the pressure plate. The plug is inserted into a gas detector. The pull frame has an n-shaped structure.
[0012] By adopting the above technical solution, the pull frame inside the mounting frame pulls the pressure plate, and then the insert on the pressure plate is inserted into the gas detector. The gas detector is then fixed and limited, and at the same time, the gas detector is lifted by the support legs. This allows the lower end of the gas detector to be in complete contact with the air, thus avoiding the problem of air intake obstruction in existing technologies and ensuring the accuracy of detection.
[0013] Preferably, the clamping member further includes a drive slide frame that is fixedly connected to the pull frame. A drive rod is slidably connected inside the drive slide frame. A stepper motor is fixedly connected to the end of the drive rod. The stepper motor is fixedly connected to the mounting frame. The drive rod has an L-shaped structure.
[0014] By adopting the above technical solution, after the gas detector is inserted into the mounting frame at the four corners and connected to the limiting frame, the stepper motor will drive the end of the rod to slide inside the drive slide frame. In this way, the slide frame is driven under the limit of the pulled frame, and the pulled frame will drive the insertion post on the pressure plate to insert and fix the gas detector.
[0015] Preferably, the inner wall of the drive slide frame is provided with a mating groove, the outside of the drive slide frame is abutted and fitted with a baffle, a spring is connected and fixed on the baffle, the other end of the spring is connected and fixed to the mounting frame, and the baffle is slidably connected to the mounting frame.
[0016] By adopting the above technical solution, after the drive slide frame moves to the farthest end, it will abut against the baffle and compress the spring. Then, the mating groove inside the drive slide frame will engage with the end of the drive rod. This ensures the stability of the drive slide frame after it moves and guarantees the fixed stability of the gas detector.
[0017] Preferably, a plurality of limiting frames are fixedly connected to the mounting frame, the limiting frames are inserted into the insert post, and the limiting frames are inserted into the gas detector.
[0018] By adopting the above technical solution, the limiting frame can limit the gas detector to a certain extent, which facilitates the precise fixing of the gas detector.
[0019] Preferably, the bottom surface of the support leg is fitted with a cushioning pad, and the support leg and the cushioning pad are connected and fixed to the top surface of the electric tracked vehicle by bolts.
[0020] By adopting the above technical solution, the buffer pad can buffer and reduce shock for the clamping parts.
[0021] 3. Beneficial effects.
[0022] Compared with existing technologies, the advantages of this application are as follows.
[0023] 1. This application, through the design of the clamping component, allows the pressure plate to be pulled by the pull frame inside the mounting frame, and then the insertion post on the pressure plate is inserted into the gas detector, thereby fixing and limiting the gas detector. At the same time, the gas detector is lifted by the support legs, so that the lower end of the gas detector can be fully in contact with the air. This avoids the problem of air intake obstruction in the prior art and ensures the accuracy of detection.
[0024] 2. After the drive slide frame moves to its farthest point, it will abut against the baffle and compress the spring. Then, the mating groove inside the drive slide frame will engage with the end of the drive rod. This ensures the stability of the drive slide frame after it moves and guarantees the fixed stability of the gas detector. Attached Figure Description

[0029] The present application will be further described in detail below with reference to the accompanying drawings.
[0030] Reference Figure 1 and Figure 2 This application discloses a coal mine gas monitoring device. Electric tracked vehicle 1.
[0031] Gas detector 2 is mounted and fixed to the top surface of electric tracked vehicle 1 by clamping component 3.
[0032] The clamping component 3 includes a support leg 4 that is fixedly connected to the top surface of the electric tracked vehicle 1. A mounting frame 5 is fixedly connected to the upper end of the support leg 4. A pull frame 6 is slidably connected to the mounting frame 5. A pressure plate 7 is fixedly connected to the end of the pull frame 6. A plug 8 is fixedly connected to the inner end of the pressure plate 7. The plug 8 is inserted into the gas detector 2. The pull frame 6 has an n-shaped structure.
[0033] The pull frame 6 inside the mounting frame 5 pulls the pressure plate 7, and then the insertion post 8 on the pressure plate 7 is inserted into the gas detector 2. The gas detector 2 will then be fixed and limited, and at the same time the gas detector 2 is lifted by the support leg 4. This allows the lower end of the gas detector 2 to be in complete contact with the air, thus avoiding the problem of air intake obstruction in the existing technology and ensuring the accuracy of the detection.
[0034] Reference Figure 3 The clamping component 3 also includes a drive slide frame 9 that is connected and fixed to the pull frame 6. A drive rod 10 is slidably connected inside the drive slide frame 9. A stepper motor 11 is connected and fixed to the end of the drive rod 10. The stepper motor 11 is connected and fixed to the mounting frame 5. The drive rod 10 has an L-shaped structure.
[0035] After the gas detector 2 is inserted into the mounting frame 5 at its four corners and connected to the limiting frame 15, the stepper motor 11 will drive the end of the rod 10 to slide inside the drive slide frame 9. In this way, the slide frame 9 is driven under the limit of the pull frame 6, and the pull frame 6 will drive the insertion post 8 on the pressure plate 7 to insert and fix the gas detector 2.
[0036] The inner wall of the drive slide frame 9 is provided with a mating groove 12, and the outside of the drive slide frame 9 is abutted and mated with a baffle 13. A spring 14 is connected and fixed on the baffle 13, and the other end of the spring 14 is connected and fixed to the mounting frame 5. The baffle 13 and the mounting frame 5 are slidably connected.
[0037] After the drive slide frame 9 moves to its farthest point, it will abut against the baffle 13 and compress the spring 14. Then, the mating groove 12 inside the drive slide frame 9 will engage with the end of the drive rod 10. This ensures the stability of the drive slide frame 9 after it moves and ensures the fixed stability of the gas detector 2.
[0038] Reference Figure 2 Multiple limiting frames 15 are fixedly connected to the mounting frame 5. The limiting frames 15 are plugged into the insert post 8 and the limiting frames 15 are plugged into the gas detector 2.
[0039] The limiting frame 15 can limit the gas detector 2 to a certain extent, so as to accurately fix the gas detector 2.
[0040] Reference Figure 1 The bottom surface of the support leg 4 is fitted with a buffer pad 16, and the support leg 4 and the buffer pad 16 are connected and fixed to the top surface of the electric tracked vehicle 1 by bolts.
[0041] The cushioning pad 16 can cushion and reduce shock for the clamping part 3.
[0042] The implementation principle of a coal mine gas monitoring device according to an embodiment of this application is as follows: After the gas detector 2 is inserted into the mounting frame 5 at its four corners and connected to the limiting frame 15, the stepper motor 11 will drive the end of the rod 10 to slide inside the drive slide frame 9. In this way, the slide frame 9 is driven under the limit of the pull frame 6, and the pull frame 6 will drive the insert 8 on the pressure plate 7 to insert and fix the gas detector 2. After the drive slide frame 9 moves to the farthest end, it will abut against the baffle 13 and compress the spring 14. Then the mating groove 12 inside the drive slide frame 9 will engage with the end of the drive rod 10. This can ensure the stability of the drive slide frame 9 after movement and ensure the fixed stability of the gas detector 2. Then the electric tracked vehicle 1 drives the gas detector 2 to move inside the mine to detect the gas concentration.
