Description

Technical Field

[0001] The utility model relates to a damper or fireproof partition door with a linkage vehicle-blocking net for a monorail crane. Background Art

[0002] Monorail cranes are widely used in underground coal mine tunnels. For ventilation and fire prevention requirements, dampers or fire partition doors need to be installed at corresponding locations in the underground coal mine tunnels. Before the monorail crane passes through the damper or fire partition door, the damper or fire partition door must be opened first to allow the monorail crane to pass. If the damper or fire partition door fails to open in time due to human or electrical failure, the monorail crane will collide with the damper or fire partition door, not only causing damage to the damper but also causing economic losses. More importantly, this will cause the coal mine's ventilation system to become disordered, posing a serious threat to miner safety and the overall operation of the mine. For dampers or fire partition doors, please refer to CN221568602U. Summary of the Invention

[0003] The technical problem to be solved by the utility model is how to overcome the above-mentioned defects of the prior art and provide a damper or fireproof partition door with a linkage vehicle-blocking net for a monorail crane.

[0004] In order to solve the above technical problems, the present monorail crane adopts a damper or fireproof partition door scheme with a linkage vehicle-blocking net, which includes a door frame, two door leaves and a driving cylinder. The driving cylinder includes a cylinder body, a piston and a piston rod. The piston is arranged in the cylinder body and divides the internal space of the cylinder body into a front chamber and a rear chamber, and is equipped with an electric control valve group, which is connected to the underground high-pressure air supply pipe through a manual or electric control valve group. It is characterized in that: a vertical hinged door axis is provided on the side wall of the tunnel in front of the door frame and / or behind the door frame, a movable door frame is fixed on the vertical hinged door axis, a nylon net is provided on the movable door frame, a horizontal swing arm is provided on the vertical hinged door axis, a pull rope is tied to the free end of the horizontal swing arm, and the tunnel roof or anchor net above it is fixed on the vertical hinged door axis. There are multiple fixed pulleys on it, and the other end of the pull rope is fixed on the outer end of the piston rod after passing around the fixed pulley. A torsion spring is also provided on the vertical hinged door shaft. When the driving cylinder drives the two door leaves to open, the pull rope overcomes the elastic force of the torsion spring under the pulling of the piston rod, and drives the vertical hinged door shaft to rotate through the horizontal rocker bar, thereby driving the movable door frame so that the movable door frame is attached to the adjacent alley (i.e. the side wall of the alley), and the movable door frame is in an open state; when the driving cylinder drives the two door leaves to close, the piston rod extends, releasing the pull rope, and the torsion spring rebounds, driving the vertical hinged door shaft to reverse, thereby blocking the movable door frame in front of or behind the door frame, and the movable door frame is in a closed state.

[0005] With this design, the movable door frame and the nylon net on it constitute a linkage vehicle-blocking net installed in front of or behind the door frame of the existing damper or fire partition door. When the damper or fire partition door is opened, the linkage vehicle-blocking net is abutted against the adjacent alley, facilitating the passage of the monorail crane; when the damper or fire partition door fails to open, the linkage vehicle-blocking net cannot be opened either, but is blocked in front of or behind the damper or fire partition door. When the crane driver sees it, he can stop the car in time. Even if he cannot stop the car in time, the crane will first hit the linkage vehicle-blocking net and be stopped by the linkage vehicle-blocking net, so that the damper or fire partition door will not be damaged, and the crane will not suffer major damage, thereby protecting the safety of equipment and personnel.

[0006] The second scheme of the damper or fireproof partition door with a linkage vehicle-blocking net for a monorail crane of the present invention includes a door frame, two door leaves and a driving cylinder, wherein the driving cylinder includes a cylinder body, a piston and a piston rod, the piston is arranged in the cylinder body, and divides the internal space of the cylinder body into a front chamber and a rear chamber, and is equipped with an electric control valve group, which is connected to the underground high-pressure air supply pipe through a manual or electric control valve group, and is characterized in that: a vertical hinged door shaft is provided on the side wall of one side of the tunnel in front of the door frame and / or behind the door frame, a movable door frame is fixed on the vertical hinged door shaft, a nylon net is provided on the movable door frame, and a horizontal swing arm is provided on the vertical hinged door shaft, and it also includes a second driving cylinder, the second driving cylinder includes a cylinder body, a piston and a piston rod, the piston is arranged in the cylinder body The cylinder body is hinged at the outer end of the piston rod of the second driving cylinder through a vertical axis, and the root of the cylinder body of the second driving cylinder is hinged and fixed through another vertical axis. The second driving cylinder is linked with the driving cylinder. When the driving cylinder drives the two door leaves to open, the second driving cylinder drives the vertical hinged door axis to rotate through the horizontal rocker, thereby driving the movable door frame so that the movable door frame is affixed to the adjacent door frame, and the movable door frame is in an open state; when the driving cylinder drives the two door leaves to close, the second driving cylinder drives the vertical hinged door axis to reverse through the horizontal rocker, thereby blocking the movable door frame in front of or behind the door frame, and the movable door frame is in a closed state.

[0007] With this design, the second driving cylinder is used to control the linked car-blocking net, and the torsion spring can be omitted, which is more reliable.

[0008] As an optimization, the front chamber of the driving cylinder and the front chamber of the second driving cylinder are connected in parallel to the two interfaces of a tee, and the rear chamber of the driving cylinder and the rear chamber of the second driving cylinder are connected in parallel to the two interfaces of another tee. The remaining interfaces of the two tees are respectively connected to the manual or electric control valve group, which is controlled and operated synchronously by the manual or electric control valve group. With this design, a set of manual or electric control valve groups can simultaneously control the driving cylinder and the second driving cylinder, eliminating the need for a separate manual or electric control valve group. Of course, the driving cylinder and the second driving cylinder are preferably cylinders with the same structure.

[0009] The air door or fireproof partition door with a linkage vehicle-blocking net for the monorail crane has a simple structure, is safe and reliable, and is suitable for use in coal mine tunnels where monorail cranes are installed. BRIEF DESCRIPTION OF THE DRAWINGS
