Description

Technical Field

[0001] This utility model relates to the field of industrial and mining monitoring devices, and in particular to a ventilation duct mounting bracket for coal mine monitoring. Background Technology

[0002] In coal mine construction or mining, structures such as ventilation ducts are frequently used to ensure the safety of the underground environment and reduce the impact of dust on the environment. Currently, common ventilation duct structures often use relatively soft fabric extending into the mine tunnel, which can improve overall safety performance while significantly reducing overall costs, and is therefore widely used. However, this type of structure cannot quickly install related supporting equipment, and cannot fully reflect wind speed and overall flow, thus affecting the real-time monitoring by sensors. This causes significant inconvenience to the normal and safe operation of the equipment and fails to meet current usage requirements. Utility Model Content

[0003] The purpose of this utility model is to provide a ventilation duct installation bracket for coal mine monitoring, which solves the technical problems of difficult installation and inability to fully monitor the safety of the ventilation duct in the prior art, and achieves the technical effect of convenient equipment installation and full monitoring of the ventilation duct.

[0004] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0005] A ventilation duct mounting bracket for coal mine monitoring includes a fixed frame and a sensor. The fixed frame consists of two sets of overlapping semi-circular metal frames with a limit plate at the opening for fixed connection. A mounting bracket is located at the top of the fixed frame and is fixedly connected to the fixed frame by welding. A connecting ring is fixed to the upper end of the mounting bracket. The sensor is located on one side of the fixed frame, facing the center of the fixed frame. A mounting plate is located on the side of the sensor closest to the fixed frame, and the mounting plate is detachably connected to the sensor by bolts. Connecting seats are located on both sides of the mounting plate, and threaded holes are located on the inner side of the connecting seats. Bolts are used to detachably connect the connecting seats to the fixed frame inside the threaded holes. A folding plate is rotatably connected to the lower part of the mounting plate, located below the sensor. One end of the folding plate, facing the sensor, has a pressure transmission plate. The pressure transmission plate is used to apply pressure to the sensor's sensing position in conjunction with the folding plate.

[0006] As an improvement, the outer side of the fixing frame is coated with an anti-corrosion coating, and the opening of the fixing frame is equipped with a protective sleeve. The protective sleeve is made of rubber and its diameter is larger than the diameter of the steel pipe of the fixing frame. It is used to protect the port opening of the fixing frame and prevent scratches on the air duct.

[0007] As an improvement, the sensor has a terminal block on the side near the mounting bracket, and the outer side of the terminal block has a protective ring to improve the strength of the wiring connection.

[0008] As an improvement, the width of the mounting plate is greater than the width of the fixing frame, a connecting ring is fixed on the side of the mounting plate away from the sensor, the side edges of the folding plate have rounded corners, and the pressure transmission plate is made of rubber.

[0009] The beneficial effects of this utility model are as follows: by setting up structures such as fixing frames and mounting frames, it is easy to fit on the outside of the air duct, which facilitates the overall installation and provides a better fixing effect. By setting up sensors and pressure transmission plates, it can better adapt to changes in the shape of the air duct, thereby enabling better safety supervision. Attached Figure Description

[0013] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0014] like Figure 1 and Figure 2As shown, a ventilation duct mounting bracket for coal mine monitoring includes a fixed frame 1 and a sensor 6. The fixed frame 1 consists of two sets of overlapping semi-circular metal frames, with a limiting plate 2 at the opening for fixed connection. The top of the fixed frame 1 is provided with a mounting bracket 3, which is fixedly connected to the fixed frame 1 by welding. A connecting ring 4 is fixed to the upper end of the mounting bracket 3. The sensor 6 is located on one side of the fixed frame 1 and is positioned towards the center of the fixed frame 1. The side of the sensor 6 near the fixed frame 1 is provided with a mounting plate 5, which is detachably connected to the sensor 6 by bolts. The mounting plate 5 has connecting seats on both sides, and the inner side of the connecting seats has threaded holes. The inner side of the threaded holes is provided with bolts for detachable connection to the fixed frame 1. A folding plate 8 is rotatably connected to the lower part of the mounting plate 5. The folding plate 8 is located below the sensor 6. One end of the folding plate 8 facing the sensor 6 is provided with a pressure transmission plate 9, which is used to cooperate with the folding plate 8 to move towards the sensing position of the sensor 6 to apply pressure. The folding plate 8 can be connected with multiple sets of rotating pins to facilitate the fitting of the air duct in different positions. One end of the folding plate 8 is equipped with a limit plate to limit its maximum folding angle.

[0015] The outer side of the mounting bracket 1 has an anti-corrosion coating, and the opening of the mounting bracket 1 has a protective sleeve made of rubber with a diameter larger than that of the steel pipe of the mounting bracket 1. This protective sleeve protects the opening of the mounting bracket 1 and prevents scratches on the air duct. The sensor 6 has a terminal block 7 on the side near the mounting frame 3, and the terminal block 7 has a protective ring on its outer side to improve the strength of the wiring connection. The width of the mounting plate 5 is greater than the width of the mounting bracket 1, and a connecting ring 4 is fixed to the side of the mounting plate 5 away from the sensor 6. The side edges of the folding plate 8 have rounded corners, and the pressure transmission plate 9 is made of rubber. A status indicator light is located on one side of the sensor 6. This status indicator light can display the current operating status of the device or provide a light alarm.

[0016] When in use, the operator can hold the fixed frame 1, install it with the opening facing the air duct, and attach one end of the folding plate 8 to the air duct, while setting the other end so that the pressure transmission plate 9 faces the sensor 6. At this time, the device can be fixed by using a cable and connecting ring 4, and the wiring can be connected through the terminal block 7. When the air duct is running, it will bulge, at which time the folding plate 8 will be pushed towards the sensor 6. The sensor 6 will receive the corresponding contact signal and pressure information, thereby determining the current operating status of the air duct and achieving stable monitoring.
