Description

Technical Field

[0001] This utility model belongs to the field of coal mine ventilation technology, specifically, it relates to a prefabricated mine ventilation door. Background Technology

[0002] Coal mine ventilation refers to the use of ventilation systems to maintain air circulation and freshness within the working area of ​​a coal mine, in order to ensure the safety of miners and a good working environment. Coal mine ventilation systems typically include equipment such as ventilation shafts, ventilation roadways, fans, and air doors. Coal mine ventilation arches are generally referred to as ventilation roadways, and they are important facilities used to ensure air circulation and ventilation within the coal mine.

[0003] In order to effectively control airflow and regulate and manage the operation of ventilation systems in coal mines or other industrial sites, ventilation doors are usually installed at one end of ventilation roadways. However, during the installation and use of ventilation doors, when the wind force flowing in the ventilation roadway is too strong, it may be difficult to further support and stabilize the ventilation door frame, thereby significantly reducing the stability between the ventilation door frame and the ventilation roadway, which may lead to the risk of the ventilation door tipping over due to the wind in the roadway.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a prefabricated mine ventilation door to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A prefabricated mine ventilation door includes a mounting steel frame, on which a ventilation door body is hinged. A support frame is detachably connected to the outer wall of the mounting steel frame. The support frame has a first threaded hole and a first bolt threaded onto it. A first U-shaped steel plate is detachably mounted on the support frame via the first bolt.

A second bolt is threaded onto the support frame, and a second U-shaped steel plate is detachably mounted on it via the second bolt, with the second U-shaped steel plate positioned above the first U-shaped steel plate. A second telescopic rod is hinged to the outer wall of the second U-shaped steel plate, and the bottom of the second telescopic rod is hinged to the outer wall of the first telescopic rod.

[0008] Preferably, the mounting steel frame has mounting holes, and a triangular steel plate is welded to the outer side wall of the mounting steel frame.

[0009] By setting mounting holes and triangular steel plates, it is possible to easily install the mounting steel frame on the ventilation roadway of the coal mine.

[0010] Preferably, an adhesive plate is fixedly connected to the outer side wall of the ventilation door body, a hydraulic telescopic rod is hinged to the adhesive plate, and a vertical rod is fixedly connected to the outer side wall of the support frame, the vertical rod being rotatably connected to the end of the hydraulic telescopic rod away from the adhesive plate.

[0011] By setting up a bonding plate, a hydraulic telescopic rod, and a vertical rod, the ventilation door body is buffered, supported, and reset.

[0012] Preferably, a right-angle steel is detachably connected between the support frame and the mounting steel frame.

[0013] By incorporating right-angle steel, the connection between the steel frame and the support frame can be easily installed.

[0014] Preferably, the right-angle steel is threaded with a third bolt, and the right-angle steel is detachably installed between the support frame and the mounting steel frame via the third bolt.

[0015] The right-angle steel was fixedly installed by setting a third bolt.

[0016] Preferably, a washer is tightly attached to the third bolt, and the third bolt movably penetrates the interior of the washer.

[0017] By adding shims, the third bolt was added to secure the right-angle steel.

[0018] In summary, the technical effects and advantages of this utility model are as follows: This prefabricated mine ventilation door, through the cooperation of the first bolt and the second bolt, installs the second U-shaped steel plate and the first U-shaped steel plate on the support frame. Through the cooperation of the first telescopic rod and the second telescopic rod, the positions of the second U-shaped steel plate and the first U-shaped steel plate can be adjusted so that the first U-shaped steel plate and the second U-shaped steel plate are in a suitable supporting position. Furthermore, the base plate increases the stability below the first telescopic rod, thereby facilitating the stable support of the support frame and increasing the fit between the installed steel frame and one end of the ventilation roadway, avoiding the risk of the installed steel frame being blown over due to excessive wind force.

[0019] By using right-angle steel, third bolts, and washers, the support frame is connected to the installation steel frame. Then, by using the fitting plate, hydraulic telescopic rod, and vertical rod, the ventilation door body can be easily supported and reset, thus facilitating the exhaust of underground air through the ventilation roadway.
