Description

Technical Field

[0001] This utility model relates to the field of ventilation resistance detection technology, specifically to a safety evaluation device for detecting ventilation resistance in mine roadways. Background Technology

[0002] Ventilation is the lifeline of a mine, and ventilation resistance is the "blood clot" in this lifeline. Ventilation resistance testers are used to detect the distribution of these resistances, diagnose the mine's ventilation conditions, and understand the resistance distribution so that targeted adjustments can be made to the mine's ventilation status.

[0003] For example, the Chinese patent for ventilation resistance detector with patent application number 201922431284.0 has a solar cell and a storage battery installed inside the casing. The solar cell is electrically connected to the solar panel through connecting wires. When the storage battery is depleted, the solar cell can provide power, which greatly improves its endurance. At the same time, the solar panel generates electricity, which not only saves energy but also protects the environment.

[0004] However, the aforementioned patent requires the ventilation resistance detector to be fixed to the testing device using bolts or other means. This results in operators spending a significant amount of time installing and disassembling the ventilation resistance detector, which severely impacts the efficiency of maintenance and replacement of the ventilation resistance detector. Utility Model Content

[0006] This application provides a safety evaluation equipment for detecting ventilation resistance in mine roadways, including a shock-absorbing base. The shock-absorbing base has a shock-absorbing groove inside, and a detection frame is movably connected inside the shock-absorbing groove through a shock-absorbing mechanism. A ventilation resistance detector is fixedly connected to one side of the detection frame through a clamping mechanism.

[0007] By adopting the above technical solution, this device can quickly diagnose the ventilation conditions of the mine through a ventilation resistance detector, thereby greatly improving the safety of the mine.

[0008] Optionally, the damping mechanism includes a buffer plate installed at the bottom of the ventilation resistance detector and slide rods arranged on both sides inside the damping groove. The four bottom corners of the buffer plate are fixedly connected to a first connecting seat, and the two sides of the slide rods are movably connected to a second connecting seat. A connecting rod is hinged to the top of the second connecting seat, and the other end of the connecting rod is hinged to the first connecting seat. A first damping damping spring is provided on the outer surface of the slide rod between the two second connecting seats. The two sides of the buffer plate are movably connected to the damping base through guide components.

[0009] By adopting the above technical solution, this device can effectively reduce the vibration amplitude of the ventilation resistance detector when it is affected by vibration inside the mine roadway through the vibration damping mechanism. This can effectively prevent the precision components inside the ventilation resistance detector from loosening or even falling off due to large vibrations, thereby greatly improving the vibration damping and safety of the device.

[0010] Optionally, the clamping mechanism includes a fixed plate installed on one side of the testing frame. A motor is fixedly connected to one side of the fixed plate. The output end of the motor extends into the inner cavity of the fixed plate and is fixedly connected to a positive and negative lead screw. Both ends of the positive and negative lead screws are movably connected to lead screw nuts. The top of the lead screw nuts extends through a groove to the top of the fixed plate and is fixedly connected to a clamping plate.

[0011] By adopting the above technical solution, the device can quickly fix the ventilation resistance detector through the clamping mechanism, which greatly facilitates the installation and disassembly of the ventilation resistance detector by the operator, and thus greatly improves the efficiency of the device in replacing and maintaining the ventilation resistance detector.

[0012] Optionally, the guide assembly includes a guide groove formed on the top of the shock-absorbing base, a guide rod fixedly connected to the bottom of the inner cavity of the guide groove, a guide plate movably connected to the outer surface of the guide rod, and the other end of the guide plate fixedly connected to the buffer plate.

[0013] By adopting the above technical solution, this device can guide and limit the ventilation resistance detector through the guide component, thereby preventing the ventilation resistance detector from swaying left and right when vibrating.

[0014] Optionally, a sponge sleeve is fixedly connected to the outer surface of the clamping plate.

[0015] By adopting the above technical solution, the use of a sponge sleeve can reduce the clamping wear of the air resistance detector by the clamping plate.

[0016] Optionally, a second damping spring is provided on the outer surface of the guide rod located below the guide plate.

[0017] By adopting the above technical solution, the vibration amplitude of the ventilation resistance detector can be further reduced by utilizing the damping effect of the second damping spring, thereby greatly improving the damping effect of the device.

[0018] Optionally, a protective plate is installed on the top of the testing frame.

[0019] By adopting the above technical solution, the device can be protected by a protective plate, thereby greatly improving the safety of the device.

[0020] Optionally, a controller is fixedly connected to one side of the testing frame.

[0021] By adopting the above technical solution, the electrical components inside this device can be controlled more conveniently using a controller.

[0022] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0023] This technical solution, by incorporating a fixing plate, motor, positive and negative lead screws, lead screw nuts, sliding grooves, and clamping plates, allows the device to quickly fix the ventilation resistance detector using a clamping mechanism. This greatly facilitates the installation and disassembly of the ventilation resistance detector by operators, thereby significantly improving the efficiency of replacing and maintaining the detector. Furthermore, by incorporating a buffer plate, sliding rod, first connecting seat, second connecting seat, connecting rod, guide groove, guide rod, guide plate, first damping spring, and second damping spring, this technical solution effectively reduces the vibration and sway amplitude of the ventilation resistance detector when subjected to vibrations within the mine roadway. This effectively prevents the loosening or even detachment of precision components inside the ventilation resistance detector due to excessive vibration, thus greatly improving the device's vibration damping and operational safety.

[0031] By adopting the above technical solution, this device can quickly diagnose the ventilation conditions of the mine through the ventilation resistance detector 4, thereby greatly improving the safety of the mine.

[0032] In the embodiments of this application, such as Figure 1 and Figure 3 As shown, the damping mechanism includes a buffer plate 6 installed at the bottom of the ventilation resistance detector 4 and slide rods 7 arranged on both sides inside the damping groove 12.

The outer surface of the slide rod 7 located between the two second connecting seats 9 is provided with a first damping damping spring 11. The two sides of the buffer plate 6 are movably connected to the damping base 1 through the guide assembly.

[0033] By adopting the above technical solution, this device can effectively reduce the vibration amplitude of the ventilation resistance detector 4 when it is affected by vibration inside the mine roadway through the vibration damping mechanism. This can effectively prevent the precision components inside the ventilation resistance detector 4 from loosening or even falling off due to large vibrations, thereby greatly improving the vibration damping and safety of this device.

[0034] In the embodiments of this application, such as Figure 1-2As shown, the clamping mechanism includes a fixed plate 3 installed on one side of the testing frame 2. A motor 17 is fixedly connected to one side of the fixed plate 3. The output end of the motor 17 extends into the inner cavity of the fixed plate 3 and is fixedly connected to a positive and negative lead screw 18. Both ends of the positive and negative lead screw 18 are movably connected to lead screw nuts 19. The top of the lead screw nut 19 extends to the top of the fixed plate 3 through a sliding groove 20 and is fixedly connected to a clamping plate 21.

[0035] By adopting the above technical solution, the device can quickly fix the ventilation resistance detector 4 through the clamping mechanism, which greatly facilitates the installation and disassembly of the ventilation resistance detector 4 by the operator, and thus greatly improves the efficiency of the device in replacing and maintaining the ventilation resistance detector 4.

[0036] In the embodiments of this application, such as Figure 4 As shown, the guide assembly includes a guide groove 13 formed on the top of the shock-absorbing base 1. A guide rod 14 is fixedly connected to the bottom of the inner cavity of the guide groove 13. A guide plate 15 is movably connected to the outer surface of the guide rod 14. The other end of the guide plate 15 is fixedly connected to the buffer plate 6.

[0037] By adopting the above technical solution, the device can guide and limit the ventilation resistance detector 4 through the guide component, thereby preventing the ventilation resistance detector 4 from swaying left and right when vibrating.

[0038] In the embodiments of this application, such as Figure 2 As shown, a sponge sleeve is fixedly connected to the outer surface of the clamping plate 21.

[0039] By adopting the above technical solution, the sponge sleeve can reduce the clamping wear of the clamping plate 21 on the ventilation resistance detector 4.

[0040] In the embodiments of this application, such as Figure 4 As shown, a second damping spring 16 is provided on the outer surface of the guide rod 14 located below the guide plate 15.

[0041] By adopting the above technical solution, the vibration amplitude of the ventilation resistance detector 4 can be further reduced by utilizing the damping effect of the second damping spring 16, thereby greatly improving the damping effect of the device.

[0042] In the embodiments of this application, such as Figure 1 As shown, a protective plate 5 is installed on the top of the testing frame 2.

[0043] By adopting the above technical solution, the protective plate 5 can be used to protect the device, thereby greatly improving the safety of the device.

[0044] In the embodiments of this application, such as Figure 1As shown, a controller 22 is fixedly connected to one side of the testing frame 2.

[0045] By adopting the above technical solution, the controller 22 can more conveniently control the electrical components inside the device.

[0046] In use, the operator first places the ventilation resistance detector 4 on the fixed plate 3, and then starts the motor 17 through the controller 22, causing the motor 17 to drive the positive and negative lead screws 18 to rotate. When the positive and negative lead screws 18 rotate, they will be limited by the slide groove 20 and drive the lead screw nuts 19 at both ends of the threaded part to move towards each other, so that the lead screw nuts 19 can drive the clamping plate 21 to fix and clamp the ventilation resistance detector 4, which greatly facilitates the operator's installation and disassembly of the ventilation resistance detector 4, thereby greatly improving the efficiency of the device for replacing and maintaining the ventilation resistance detector 4. When the ventilation resistance detector 4 is affected by the vibration inside the mine roadway during operation, it will drive the buffer plate 6 to move downward, so that the buffer plate 6 can drive the guide plate 15 to slide along the guide rod 14, and at the same time pass through the first connecting seat 8 on both sides and the connecting Rod 10 drives the second connecting seat 9 to slide along the slide rod 7. When the second connecting seat 9 slides, it will compress the first damping spring 11. The first damping spring 11 with damping function can greatly reduce the vibration amplitude of the ventilation resistance detector 4, thereby effectively preventing the precision components inside the ventilation resistance detector 4 from loosening or even falling off due to large vibrations. This greatly improves the vibration damping performance and safety of the device. When the guide plate 15 slides, it can effectively prevent the ventilation resistance detector 4 from swaying left and right under the guiding and limiting action of the guide groove 13. On the other hand, it can compress the second damping spring 16. At this time, the second damping spring 16 with damping function can further reduce the vibration amplitude of the ventilation resistance detector 4, thereby further improving the vibration damping effect of the device.
