TECHNICAL FIELD

[0001] The utility model relates to a single track of air door before the rail of monorail crane track alarm car stopper. BACKGROUND

[0002] The utility model discloses a kind of air door linkage monorail beam car stopper, including car stopper main body, the bottom end of the car stopper main body is equipped with compression plate, compression plate is fixedly connected with car stopper main body;Air cylinder is installed at the top of compression plate, air cylinder is installed with fixed connector on one side;The one side of the car stopper main body is installed with multiple evenly distributed pressure regulators, hydraulic cylinder is installed at the top of car stopper main body, hydraulic cylinder is installed with telescopic pipe on one side, and fixed connector and car stopper main body are fixedly connected by screw, this kind of air door linkage monorail beam car stopper, connect the pneumatic control system on air door with the air cylinder on car stopper, form air door air cylinder and the air cylinder linkage of car stopper, when air door opens, car stopper opens simultaneously, locomotive passes, when air door closes, car stopper closes simultaneously, locomotive cannot pass, to ensure that locomotive can safely pass air door, it is favorable to prevent accident from happening.

[0003] The air control system of the car stopper in the car stopper is connected with the air control system of the car stopper, parallel control is formed, under normal circumstances, air door and car stopper open simultaneously, mine car can pass smoothly. Sometimes, air door fails to open or fails to open completely due to failure or obstruction, etc., at this time, the car stopper is still opened, the mine car cannot stop in time, and the phenomenon of hitting the air door occurs from time to time.

[0004] The utility model discloses a kind of monorail crane car track linkage car stopper, involve the technical field of mine safety auxiliary transport equipment, including support frame, the center of the support frame inner chamber top is transversely installed with monorail, the right side of the monorail is provided with rotation adjusting mechanism;The rotation adjusting mechanism includes shell cover, servo motor, limit disc, shaft rod, shaft seat, drive shaft, limit rod, connecting plate and shock absorbing spring.

[0005] The application uses a buffer device to stop the passing vehicle, and the stopping force can be adjusted according to the load size, but the application does not disclose under what circumstances the air door is considered to be not opened or not completely opened, and only manual control is available.

[0006] The prior art urgently needs an alarm car stopper that can only be opened when the air door is completely opened. SUMMARY

[0007] The technical problem to be solved by this utility model is how to overcome the above-mentioned defects of the prior art and provide a single-rail hoist track alarm and vehicle stop device in front of the damper.

[0008] To solve the above-mentioned technical problems, this monorail overhead crane alarm vehicle stopper includes a monorail overhead crane vehicle stopper, an air damper controller, and an audible and visual alarm. The air damper controller includes a programmable controller and an air damper drive cylinder. The monorail overhead crane vehicle stopper includes a frame, a vehicle stopper, and a vehicle stopper drive cylinder. The vehicle stopper drive cylinder includes a cylinder body and a piston rod. The middle part of the vehicle stopper is hinged to the frame, and the top of the vehicle stopper is hinged to the outer end of the piston rod. The vehicle stopper drive cylinder and the air damper drive cylinder are each equipped with an electrically controlled valve assembly. Both of their electrically controlled valve assemblies and the audible and visual alarm are connected to the signal output terminal of the programmable controller via wires and are controlled by it.

[0009] It also includes a damper position sensor, which comprises a housing, a contact rod, a ball joint, a guide rod, and a normally open switch. The normally open switch is located inside the housing, which has a guide hole. The guide rod passes through the guide hole, and its outer end is connected to a support plate. The inner end of the guide rod can abut against the moving contact of the normally open switch. The ball joint includes a ball socket, a ball head, and a ball rod. The ball head has a cut surface that presses against the support plate. The extension line of the ball rod's axis passes through the center of the ball head. The ball rod also has an annular boss. The contact rod is located at the end of the travel of the damper when it is opened and is connected to the outer end of the ball rod. The ball rod and the guide rod are each fitted with a helical spring. The two ends of the helical spring on the ball rod abut against the annular boss and the ball socket, respectively. The two ends of the helical spring on the guide rod abut against the support plate and the housing, respectively. The normally open switch is connected in series to the wires of the electronically controlled valve group of the vehicle-driving cylinder and the signal output terminal of the programmable controller.

[0010] With this design, the guide rod can only close the normally open switch when the damper is fully open, ensuring proper continuity between the programmable controller's signal output and the solenoid valve assembly of the brake cylinder. Otherwise, the signal output of the programmable controller and the solenoid valve assembly of the brake cylinder remain open. This hardware-based design eliminates the need for the brake to release its braking function when the damper is not fully open or partially open, making it more reliable than manual operation.

[0011] As an optimization, the contact rod is also fitted with an elastic buffer sleeve. This design can buffer door panel collisions and ensure reliable operation.

[0012] This utility model of a single-rail alarm and vehicle stop device for ventilation doors is scientifically designed and reliably operated, making it suitable for use in underground coal mines. Attached Figure Description
