Disclosure of Invention
The invention aims to solve the technical problem of providing a control method of a pneumatic locomotive door, which uses a pneumatic system to control the door to be automatically opened and closed.
The above object of the present invention is achieved by the following technical solutions:
the control method of the pneumatic locomotive door is characterized in that the opening and closing actions of the locomotive door are controlled by a pneumatic system.
Further, the secondary pressing action of the locomotive door is also controlled by a pneumatic system.
The control method of the locomotive door adopts the pneumatic system to control and realize the automation (pneumatic door) of opening, closing and secondary compression, compared with the motor control, the control method of the locomotive door is economical and practical, and reduces the cost; the structure of the motor is complicated, when the motor breaks down, the maintenance is difficult, the time consumption is long, and the cost for replacing the motor is high. The pneumatic system is safe and reliable, has an explosion-proof function, and is suitable for the actual working condition of the locomotive.
Further, the air intake amount of the cylinder in the pneumatic system is adjusted to adjust the driving force and the action time when the locomotive door is opened and closed.
Further, the magnitude of the driving force when the locomotive door is opened is greater than or equal to 100N, and the magnitude of the driving force when the locomotive door is closed is greater than or equal to 200N.
In order to reduce noise and ensure air tightness, a sealing rubber strip is arranged on a door leaf of the locomotive door, the pressing force on the door leaf is larger, the sealing rubber strip on the door leaf can be compressed in place, and a lock tongue can completely extend into a lock catch box after being locked, so that the locking reliability is ensured. Through repeated tests, when the driving force for closing the door is more than or equal to 200N, the automobile door can be ensured to overcome the counterforce of the sealing rubber strip, so that the automobile door can be reliably locked. The electric control door is driven by the motor, the larger the driving force is, the larger the size of the motor is, the motor is arranged on the door frame, and the space for installation and utilization is limited, so the door closing force of the electric control door is often insufficient, and the door closing reliability is poor. Meanwhile, if the power of the motor is increased, the size of the motor is large, the meshing force of a motor gear is large, and when the manual door opening is switched, the manual door opening force is seriously influenced by the rotation resistance of the motor during power failure. When the induction system is not flexible and the locomotive is not powered for maintenance and repair, a manual door needs to be opened. The motor is too large, the larger the meshing force of the motor gear is, the door cannot be opened, and the maintenance and the repair are inconvenient.
Furthermore, when the door is opened, the lock tongue retracts into the lock body, and the door leaf rotates to be opened to the door opening position; when the door is closed, the door leaf is rotated to be closed, and when the door leaf is rotated by 90 degrees to a door closing position, the lock tongue extends out.
When the electric control door is closed, the door is closed by the motor driven by inertia, which is equivalent to a falling door, and the lock tongue impacts the lock catch box to retract into the lock body, so that the noise is high. The invention uses pneumatic control, the door leaf is closed by the driving force, the lock tongue is retracted in the lock body, and the lock tongue is extended again after the door leaf is closed to the door closing position, thereby avoiding the door from falling and closing, and having extremely low noise.
Furthermore, the execution of the door opening and closing actions of the locomotive door is controlled by a sensing system, and sensing areas are set to be 3.5-4.5 m on two sides of the locomotive door; when the door is opened, when a person approaches the locomotive door for a distance of 3.5-4.5 m, the sensor senses and executes the door opening action, the locomotive door rotates 90 degrees in 2-3 s, and the locomotive door moves from a door closing position to a door opening position; when the personnel leave the locomotive door sensing area for 5-8 s, the locomotive door rotates 90 degrees in 3-5 s and moves from the door opening position to the door closing position.
The sensing area is 3.5-4.5 m on two sides of the locomotive door, people walk to the locomotive door from the sensing area and need 3-5 s of time, the distance of the sensing area cannot be too small, the door leaf needs time for opening, and if the distance is too small, people walk to the locomotive door and need to wait for the door to open. 3.5-4.5 m is set, the time of people walking is almost the same as the time needed by opening the door, and people can enter the door when walking to the locomotive door.
And people leave the induction area for 5-8 s and then start to close the door because people sometimes go in and out of the door, and when the system confirms that no people pass through the door, the door is closed again.
Further, the execution of the door opening action of the locomotive door is controlled by a control button; when the door is opened, a button for executing the door opening action is pressed, the locomotive door rotates 90 degrees in 2-3 s, and the locomotive door moves from a door closing position to a door opening position; the execution of the door closing action of the locomotive door is controlled by a sensing system, a sensing area is set to be 3.5-4.5 m on two sides of the locomotive door, and after personnel leave the sensing area of the locomotive door for 5-8 s, the locomotive door rotates 90 degrees in 3-5 s and moves to the door closing position from the door opening position.
When the locomotive door is a passage door between the driver cab and the machine, a plurality of components for controlling the locomotive are arranged in the machine room, the noise is high, the driver cab is close to the passage door, a button for opening the passage door can be arranged, and when a worker needs to enter the machine room, the locomotive door is opened by pressing the button.
Further, when the door is closed, the door page is set to pause.
The anti-pinch function can be achieved by setting the pause action. Because the electric control door is closed by inertia, if the door is stopped in the closing process, the later closing force is not enough, and the door cannot be closed. The pneumatic door is closed by the driving force, the closing force can be adjusted by adjusting the air inflow, and pause can occur in midway.
Furthermore, stopping for 1-2 s when the door leaf rotates for alpha degrees; the alpha is 75-85 degrees, when the alpha is 75-85 degrees, the included angle between the door leaf and the door frame is 5-15 degrees, and when the alpha is 5 degrees, the distance between the door leaf and the door frame is approximately the width of a human arm; at 15 deg., the distance between the door leaf and the door frame is about the width of human body.
Furthermore, a sensing area is arranged, when a person is in the sensing area during door closing, the door closing action is stopped and reversely moved to the initial position, and then the door closing action is executed again.
Further, when the door is closed, when the door meets the resistance of 25-80N, the door closing action is stopped, the time is delayed for 2-3 s, the door is reversely moved to the initial position, and the door closing action is executed again.
Furthermore, when the door leaf is in the door opening position, the lock tongue and the lock bolt are both positioned in the lock body, after the locomotive door moves from the door opening position to the door closing position, the air cylinder II driving the handle to rotate releases air pressure, the lock tongue extends out of the lock body under the action of the lock tongue return spring, and the lock bolt rotates anticlockwise for 45 degrees under the action of the lock bolt return spring; the cylinder II drives the handle to rotate 90 degrees anticlockwise, and the lock latch extends out of the lock body and enters the lock catch box to finish secondary compression; when the door is opened, the cylinder II drives the handle to rotate 90 degrees clockwise, the lock latch retracts into the lock body, and secondary compression is released; the second cylinder drives the handle to rotate clockwise by 45 degrees, and the lock tongue is retracted into the lock body; after the bolt enters the lock body, the door leaf is rotated to be opened to the door opening position.
When the door leaf is opened, the two pairs of handles of the air cylinder keep acting force, after the door leaf moves to the closed door position, the two pairs of handles of the air cylinder release air pressure, the two pairs of handles of the air cylinder do not exert force, and the spring bolt and the lock bolt reset under the action of the reset spring.
Compared with an electric control door, the pneumatic control locomotive door can realize automatic secondary compression, and because the force required by the pneumatic control locomotive door is more than 300N during the secondary compression, the motor of the electric control door cannot reach the large force, and the motor is required to be very large to reach the large force, which does not meet the requirement of practical application, the existing electric control door cannot realize the automatic secondary compression and is subjected to the secondary compression in a manual mode. The invention uses a pneumatic system, and the pressing force can be adjusted by adjusting the air input of the air cylinder, so that automatic secondary pressing can be realized.
The execution of the secondary pressing action can also be controlled by a control button, and whether the secondary pressing is carried out or not can be selectively selected.
Further, the air inlet amount of the second air cylinder is adjusted to adjust the driving force and the action time of the secondary compression of the locomotive door.
Further, the pneumatic system of the present invention is comprised of a programmable logic controller.
Further, a stroke switch is installed in the keeper to detect whether the latch enters the keeper.
The invention has the following beneficial effects:
compared with the control method of the electric control door, the control method of the pneumatic locomotive door has the following advantages that:
1. the air input of the door opening, door closing and secondary compression air cylinders can be adjusted, and the larger driving force is ensured; the driving force is too small, the door leaf is not pressed tightly enough, and the spring bolt cannot stretch into the lock catch box; because the driving force of the motor can not be adjusted, the motor with larger volume can be used for improving the driving force, the motor is too large, the manufacturing cost is high, and even the motor cannot be installed due to too large volume, so that the motor is not in line with the requirements of practical application. The invention is controlled by a pneumatic system, the output door closing force is constant, and the air inflation quantity of the air cylinder can be adjusted to obtain different forces so as to meet the requirements of the vehicle door under various conditions.
2. The electric control door is limited by the installation size of the motor, the motor cannot be too large, namely the driving force of the motor is limited, so that the electric control door cannot realize automatic secondary compression, and the pneumatic door can realize automatic secondary compression by adjusting the driving force by adjusting the air input of the air cylinder.
3. Double anti-pinch functions. Pause actions (double anti-pinch) can be set, so that the anti-pinch safety is improved; because the electric control door is closed by inertia, if the door is stopped in the closing process, the later closing force is not enough, and the door cannot be closed. The pneumatic door is closed by the driving force, the closing force can be adjusted by adjusting the air inflow, and pause can occur in midway. When the door is closed, when the door meets the resistance of 25-80N, the door closing action is stopped, the time is delayed for 2-3S, the door moves to the initial position in the reverse direction, and the door closing action is executed again (double anti-pinch).
4. The door closing manner is different. When the electric control door is closed, the door is closed by the motor driven by inertia, which is equivalent to a falling door, and the lock tongue impacts the lock catch box to retract into the lock body, so that the noise is high. The invention uses pneumatic control, the door leaf is closed by the driving force, the lock tongue is retracted in the lock body, and the lock tongue is extended again after the door leaf is closed to the door closing position, thereby avoiding door falling and door closing, improving safety and having extremely low noise.
5. The door opening, door closing and secondary pressing actions are automatically completed under the control of a pneumatic system, and the pneumatic system is stable in control action, high in reliability and low in failure rate.
