Description

Electric push control system for vertical rotating protective doors Technical Field

[0001] The present invention relates to the technical field related to protective equipment, and more specifically, to an electric push control system for a vertical rotating protective door. Background Art

[0002] In the prior art, a typical hydraulic drive system structure is as follows: it includes a hydraulic oil station, which uses hydraulic oil (L-HM46 type, anti-wear) as a hydraulic conductor. A three-phase asynchronous motor drives a hydraulic oil pump to build up pressure (the pressure can reach 20MPa), which enters the rod chamber (or rodless oil chamber) of the hydraulic cylinder through a high-pressure oil pipe. The pressure difference at both ends of the cylinder is used to drive the piston to move. One end of the push rod is connected to the protective door body, and the other end is connected to the bracket on the wall on one side of the protective door frame in the tunnel, thereby pushing the protective door to open or close.

[0003] Since there are many hydraulic valves, pipes and joints between the hydraulic drive system and the protective door, and the environment inside the subway is humid, daily maintenance work becomes very difficult. Missed detection or misdetection can easily cause oil leakage in the hydraulic drive system, making subway operation and maintenance work extremely inconvenient and leaving hidden dangers to subway operation. In addition, the leakage of hydraulic oil will also cause environmental pollution. Summary of the Invention

[0039] The present invention provides an electric push control system for a vertical rotating protective door. The vertical rotating door body electric cylinder opening and closing device has a simple structure, which reduces the complexity of maintenance and management. Compared with the hydraulic drive system, the vertical rotating door body electric cylinder opening and closing device does not require regular replacement of hydraulic oil, cleaning of oil circuits and maintenance of hydraulic components, which reduces maintenance costs and workload. It is a solution that complies with environmental protection and modern management.

[0040] In the present invention, the electric push control system for the vertical rotating protective door includes:

[0041] The first part is a protective door designed to be installed on a mounting base 1 (an existing building in the subway system). The protective door comprises a door frame and a vertical, pivoting, and casement-opening door body 2. The door frame is secured to the mounting base 1 using pre-buried anchor bolts, and the door body 2 is attached to the door frame via a hinge assembly. A hinge assembly is provided on one side of the door body 2, and a wheel assembly is located on the other side and at the bottom of the door body 2 to support the other side of the door body 2, thereby reducing the load-bearing pressure on the hinge assembly from the door body 2.

[0042] The second part is a vertical rotary door body electric cylinder opening and closing device for electrically opening and closing the door body 2. In the prior art, the device used to drive the door body opening and closing is a hydraulic drive system. In the present invention, the device used to drive the door body 2 opening and closing is an electric drive system with an electric cylinder structure. The vertical rotary door body electric cylinder opening and closing device includes a drive motor module 3 and a push rod 4 that is power-connected to the drive motor module 3. The vertical rotary door body electric cylinder opening and closing device is hinged relative to the mounting base 1, and the push rod 4 is hinged to the door body 2.

[0043] Specifically, the vertical rotary door electric cylinder opening and closing device includes a door body mounting base 5 for being fixedly mounted on the door body 2, an opening and closing cylinder 6, a push rod 4 movably mounted on the opening and closing cylinder 6, a door body opening and closing servo motor provided on the opening and closing cylinder 6 for providing power, a first manual rocker integrated on the door body opening and closing servo motor that can manually drive its motor output shaft to rotate, a first reducer connected to the door body opening and closing servo motor for deceleration, and a fixed base 7 fixedly arranged relative to the mounting base 1, wherein the door body opening and closing servo motor is integrated with the first manual rocker and constitutes a drive motor module 3. The door body opening and closing servo motor includes a motor output shaft, on which a manual rocker gear that rotates synchronously therewith is provided, and the first manual rocker is engaged with the manual rocker gear through a gear set for manually driving the manual rocker gear to rotate.

The telescopic movement can realize the opening and closing of the door.

[0044] The opening and closing cylinder body 6 is a long straight cylindrical structure, and a limited track is set inside the opening and closing cylinder body 6. The push rod 4 can be installed inside the opening and closing cylinder body 6 through a linear bearing. A limit groove structure that cooperates with the limit track can also be set on the push rod 4, so that the push rod 4 can move linearly inside the opening and closing cylinder body 6 while not rotating in the circumferential direction. Push rod teeth are also provided on the push rod 4 (the push rod teeth can be a rack, and the rack is directly installed on the push rod 4). The push rod teeth are arranged in a straight line along the axis of the push rod 4. The push rod 4 is slidably set in the opening and closing cylinder body 6, one end of the push rod 4 is located in the opening and closing cylinder body 6, and the other end of the push rod 4 is located outside the opening and closing cylinder body 6, so that the push rod 4 can be installed in the opening and closing cylinder body 6, and the linear bearing, the limit track and the push rod teeth do not affect each other when sliding. For example, a linear bearing is set at each end of the push rod 4, and a push rod tooth and a limit groove structure are set in the middle rod section of the push rod 4. Alternatively, a linear bearing is provided at the front end and the middle part of the push rod 4, and a push rod tooth and a limit groove structure are provided at the rear end of the push rod 4. The first reducer specifically includes a gear and a pinion, and the pinion is connected to the power of the door opening and closing servo motor.

Further, the present invention can be provided with a shell mold, and the door opening and closing servo motor and the first reducer are integrated and installed on the shell mold. A manual rocker gear can also be provided inside the shell mold, and the manual rocker gear can be installed on the motor output shaft, or meshed with the pinion of the first reducer. A gear set can be provided on the first manual rocker, and meshed with the manual rocker gear through the gear set, thereby realizing manual control. For the specific connection structure of the door opening and closing servo motor and the first manual rocker, it is a design standard to be able to realize the door opening and closing servo motor power output while being able to adopt the first manual rocker to realize power output. In addition, the first manual rocker arm can also be easily removed from the gear set (similar to a tractor that is started by hand). The present invention has a door body mounting base 5 fixedly installed on the door body 2. The door body mounting base 5 is a metal component. The door body mounting base 5 is an integrated structure. The door body mounting base 5 is fixedly set on the door body 2. The present invention has a fixed base 7 set on the door frame. The fixed base 7 is a metal component. The metal component is an integrated structure. The metal component is fixedly set on the door frame of the protective door or on the mounting base 1. One end of the opening and closing cylinder 6 is hinged to the fixed base 7 by a rotating pin, and one end of the push rod 4 is hinged to the door body mounting base 5 by a rotating pin.

[0045] Furthermore, multiple groups of vertical rotary door body electric cylinder opening and closing devices are provided, and all vertical rotary door body electric cylinder opening and closing devices are arranged at intervals in the height direction.

[0046] The third part is the protective door control system used to realize the operation control of the electric propulsion control system. The protective door control system is a redundant control system. The protective door control system includes a main controller and a backup controller. The main controller and the backup controller can independently control the operation of the electric propulsion control system, and when the main controller fails, the backup controller intervenes.

[0047] The protective door control system adopted by the present invention adopts a redundant PLC system. When the main controller of the system fails, it will automatically switch to the backup controller. If the system loses power due to overall power outage, the station main control room will diagnose that the communication of the protective door control system is abnormal, and issue a fault prompt, and then arrange for personnel to go to the protective door control room to handle it. If the protective door control system is normal and the water level sensor fails, the system can diagnose the water level sensor, determine that the water level signal is abnormal, and then issue an on-site system alarm and upload it to the station main control. The protective door control system is mainly connected to the station main control system. As long as there is a system failure (including a water level meter failure), the failure can be fed back on the main control.

[0048] The fourth part is also provided with a manual electric door locking device on the door body 2; the manual electric door locking device includes a locking servo motor 8 and a handwheel connecting rod transmission system, the handwheel connecting rod transmission system is provided on the door body 2, and a lock tongue 9 is provided at the movable end of the handwheel connecting rod transmission system, the handwheel connecting rod transmission system includes a handwheel 10, the locking servo motor 8 can be linked with the handwheel 10, the locking servo motor 8 is used to provide electric power to the handwheel connecting rod transmission system or the handwheel 10 is used to provide manual power to the handwheel connecting rod transmission system.

In the present invention, the second reducer and the locking servo motor 8 are integrated in a housing mold, thereby realizing the modularization of the components and facilitating installation.

[0050] The fifth part, the door guide and servo motor driven locking device, is used to limit and lock the door 2 when it is opened to the extreme position.

[0051] Part 6, Emergency Power Supply EPS System. The emergency power supply EPS system is connected to various electrical equipment in the electric push control system for vertical rotating protective doors and is used to provide backup power in the event of a power outage.

[0052] Furthermore, the present invention is provided with three motor devices, namely, a door opening and closing servo motor, a locking servo motor 8, and a limit servo motor. In a preferred embodiment of the present invention, the door opening and closing servo motor, the locking servo motor 8, and the limit servo motor are all servo motors with brakes (i.e., after the servo motor is powered off, the brake closes to achieve self-locking of the servo motor). The innovation of the present invention lies in the use of an electric cylinder structure (which can be understood as the door opening and closing servo motor, the locking servo motor 8, and the limit servo motor) as the power system of each actuator. Compared with the hydraulic drive system, it is more precise and reliable in terms of electrical control, and can ensure that the protective door is quickly and accurately closed when needed. In addition, the electric cylinder drive system does not have the risk of hydraulic oil leakage, thereby reducing safety hazards to the environment and equipment.

The manual electric door body locking device can be opened, closed and locked manually or automatically (manually, the staff manually opens or closes, and automatically, the servo motor drives the electric opening or closing). The door body guide and servo motor driven locking device are used to fix the position of the door body 2 when it runs to the extreme position. The protective door control system can monitor the water level status in the protective door operating range and the operating status of each device in the entire system, and send a protective door opening or closing request to the main control room according to the actual status, and perform relevant control on the entire system after receiving the instructions from the main control room. The present invention has the characteristics of simple structure, low cost, small layout space, and is compatible with the subway section line environment, which reduces the complexity of maintenance and management. All devices can be operated manually or automatically and have remote monitoring functions.

[0054] This invention utilizes a combined approach of overall design and multiple experimental studies to develop an electric cylinder structure suitable for subway protective doors. Based on design requirements, water head, and other indicators, mechanical and electrical design of the vertical rotary door electric cylinder opening and closing mechanism was performed, along with calculations of the protective door opening and closing force. While meeting civil air defense and flood prevention requirements, a non-standard design was implemented for the existing opening and closing mechanism and support mechanism to achieve the required functionality. An optimized solution was then used for trial production and various performance tests of the original hydraulic drive system to verify the protective door's opening and closing performance, flood prevention performance, operational performance, and the overall system's safety and reliability.

[0055] The above describes the structural design of an electric push control system for a vertical rotary protective door provided by the present invention.

[0058] 3. The speed of the opening and closing process of the vertical rotary door electric cylinder opening and closing device is adjustable (the opening and closing speed of the electric cylinder structure is regulated by controlling the operating speed of the door opening and closing servo motor), with better performance to meet the needs of different working conditions;

[0059] 4. The structure of the vertical rotary door body electric cylinder opening and closing device is simpler (compared to the hydraulic drive system), and the vertical rotary door body electric cylinder opening and closing device also reduces the complexity of maintenance and management. Compared with the hydraulic drive system, the vertical rotary door body electric cylinder opening and closing device does not require regular replacement of hydraulic oil, cleaning of oil circuits and maintenance of hydraulic components, which reduces maintenance costs and workload. At the same time, the vertical rotary door body electric cylinder opening and closing device has no risk of hydraulic oil leakage and is environmentally friendly.

[0060] 5. The emergency power supply EPS system is used to ensure that the protective door can be opened or closed smoothly in the event of power failure.

[0063] 1. The limit rod exits and stops when it reaches the designated position;

[0064] 2. The electric cylinder extends and the door closes. The door stops when it is fully closed.

[0065] 3. The manual electric door locking device locks into place and stops. The door closing process is complete.

[0066] In the present invention, the protective door opening operation process is as follows:

[0067] 1. The manual electric door locking device unlocks and stops when it is fully unlocked;

[0084] 2. Enhanced stability and reliability: By optimizing the design and material selection, the stability and reliability of the protective door are improved, the possibility of failure is reduced, and the service life is extended;

[0085] 3. Realize intelligent control: By introducing advanced sensors, protective door control systems and communication technologies, the door can be automatically and intelligently controlled to improve ease of use and safety.

[0086] The present application relates to a vertically rotating electric cylinder door opening and closing device for use in subway cross-river tunnels. It automatically closes in the presence of water, meeting both civil air defense and flood prevention requirements. Furthermore, the successful development of this vertically rotating electric cylinder door opening and closing device can reduce equipment and construction costs, minimize pipeline construction, lower operating and maintenance costs, and optimize the subway environment.

[0087] The purpose of the present invention is to improve the deficiencies in the prior art and provide a control system for vertical rotating protective doors that has a reasonable design, simple structure, small footprint, good safety and reliability. The system is operated in two control modes: manual and servo motor drive, and can realize intelligent remote control. The control system for vertical rotating protective doors provided by the present invention includes: an installation base 1 (civil engineering supporting facilities), a protective door, a door guide and servo motor driven locking device, a manual electric door locking device, a vertical rotating door electric cylinder opening and closing device, and a protective door control system. The protective door control system is respectively connected to the door guide and servo motor driven locking device, the vertical rotating door electric cylinder opening and closing device, and the manual electric door locking device (for realizing the opening and closing control of the above-mentioned devices).

[0088] The vertical rotating door body electric cylinder opening and closing device is installed on the back of the door body 2 of the protective door, and includes a fixed base 7 (fixed on the mounting base 1 by pre-buried anchor bolts or other structures), a first rotating pin, a second rotating pin, and an electric cylinder assembly. The electric cylinder assembly includes an electric cylinder (opening and closing cylinder body 6), a push rod 4, and a drive motor module 3. The electric cylinder (opening and closing cylinder body 6) is hingedly fixed to the mounting bracket of the fixed base 7 by the first rotating pin. One end of the electric cylinder (opening and closing cylinder body 6) is hinged to the first rotating pin, and the other end is connected to the push rod 4. The other end of the push rod 4 is connected to the door body mounting base 5 by the second rotating pin. In actual application, the vertical rotating door body electric cylinder opening and closing device can be set to multiple groups arranged horizontally above and below the door body 2 according to the opening and closing resistance of the door body 2. In the embodiment of the present invention, only one group is set. The device has a simple structure and a compact layout, which can meet the installation requirements of a small space. The optimal fixing point is calculated based on the actual opening resistance to meet the requirements of rapid opening and closing of the protective door.

[0089] The manual electric door locking device is installed on the front of the door body of the protective door, and includes a handwheel 10, a gear transmission pair 11, a locking servo motor 8, a guide rod mounting seat 12, a guide rod 13, a connecting rod connecting bracket 14, a connecting rod 15, and a lock tongue 9. The handwheel 10 is connected to the input end of the second reducer, and the driven gear of the gear transmission pair 11 is fixed to the output shaft of the handwheel 10. The driving gear of the gear transmission pair 11 is fixed to the output shaft of the locking servo motor 8. The guide rod 13 is fixed to the output shaft of the second reducer and can slide up and down in the guide rod mounting seat 12. In the present invention, when the manual electric door locking device receives a locking signal from the remote monitoring system, the locking servo motor 8 drives the driving gear of the gear transmission pair 11, which drives the input end of the second reducer after being transmitted through the driven gear, thereby driving the guide rod 13 to move downward. At this time, the connecting rod connecting bracket 14 moves downward together with the guide rod 13, and the connecting rod 15 slides up and down in the guide rod mounting seat 12, driving the connecting rod 15 to move downward, so that the lock tongue 9 finally reaches the locked position, completing the locking of the door body 2. When the device receives the unlocking signal from the remote monitoring system, the movement of the device is opposite to the above process. The present device can be switched between manual mode and automatic mode. In manual mode, the brake of the locking servo motor 8 is unlocked (the present invention can provide a backup power supply for supplying power to the locking servo motor 8 in the event of a power outage to drive the brake to unlock), and the operator directly turns the handwheel 10 to operate. In automatic mode, the system drives the locking servo motor 8 to complete the corresponding operation.

[0090] The protective door control system consists of two independent control systems, one located within the protective door sections of the left and right tunnels of the station. The protective door control room is responsible for monitoring the operating status of the protective doors and their associated equipment, comparing and verifying water level signals from water level sensors, and, based on the verification results, transmitting corresponding operation requests to the station control room's main control system (also known as the station main control room). When door closing or opening is required, operators send a closing or opening signal through the protective door control room. Only after approval from the station main control room can manual closing or opening commands be issued. The protective door control room controls the corresponding devices to implement the door opening or closing commands. Water level sensors are located in the lowest section pump room of each protective tunnel. Their automatic alarm limits and water level rise limits can be set according to relevant standards or actual conditions. When the water level or rate of rise exceeds the set limits, the protective door control room sends an alarm signal and a door closing request to the station main control room. The station main control room then determines the appropriate operation and issues instructions. The protective door control room then carries out the corresponding operation after receiving the instructions from the main control room.

[0091] The door guide and servo motor-driven locking device, the vertical rotary door electric cylinder opening and closing device, and the manual electric door locking device are connected to the remote monitoring system. Door 2 is equipped with a position sensor or travel switch for detecting door 2's position. The door guide and servo motor-driven locking device can be operated in either manual or automatic modes. In manual mode, the limit servo motor brake is unlocked, and the opening, closing, or locking of door 2's limit positions is entirely manual.

[0092] When the electric push control system of the present invention receives a command to open the protective door and needs to automatically open the door, the various systems work together as follows: the manual electric door locking device performs the unlocking operation. Then, the vertical rotary door electric cylinder opening and closing device performs the door opening operation, that is, the electric cylinder structure pulls back, driving the door body 2 to open, until the door body 2 opens to the specified position. Finally, the door body guide and servo motor drive the locking device to lock the door body 2. That is, when the door body 2 opens to a position close to the limit, the guide slider guides and decelerates the door body 2. When the door body 2 reaches the limit position, the door body 2 stops moving, and the limit servo motor drives the limit rod 18 to complete the locking of the door body 2. Similarly, when the electric push control system receives a command to close the protective door and needs to automatically close the door, its collaborative working sequence is the opposite of the above-mentioned actions. That is, first, the door body guide and servo motor drive the locking device to unlock, then the vertical rotary door electric cylinder opening and closing device closes the door body 2 to the limit position, and finally, the manual electric door locking device completes the locking of the door body 2.

[0093] The electric push control system for a vertical rotating protective door provided by the present invention has the following specific structure: it includes a door guide and servo motor driven locking device, a vertical rotating door electric cylinder opening and closing device, a manual electric door locking device, and a remote monitoring system (protective door control system). The protective door control system is connected to the door guide and servo motor driven locking device, the vertical rotating door electric cylinder opening and closing device, and the manual electric door locking device (controlled by cables). The door guide and servo motor driven locking device consists of a limit rod 18, a locking servo motor 8, a limit seat 19, and other structures. The limit rod 18 is installed at the bottom of the cantilever end of the door body 2 of the protective door. After the door body 2 is opened and reaches the limit position, the limit rod 18 can be lowered (this action can be completed manually, similar to a latch structure; it can also be completed electrically, that is, driven by the limit servo motor, and the fiber servo motor receives instructions to complete the extension and retraction action) and inserted into the limit seat 19, thereby locking the door body 2.

[0094] The vertical rotary door body electric cylinder opening and closing device (except the limit seat 19) is installed on the back of the protective door, including the elevator mounting base 17 and the limit rod 18. The limit rod 18 is arranged on the elevator mounting base 17 so that it can be raised and lowered. The limit servo motor is installed on the elevator mounting base 17. A screw rod 20 is arranged on the elevator mounting base 17. The limit servo motor drives the screw rod 20 to rotate through a third reducer. The screw rod 20 cooperates with the elevator mounting base 17 to achieve up and down lifting. The screw rod 20 is connected to the limit rod 18 through a rotatable joint, so that the limit rod 18 can be lifted and lowered with the movement of the screw rod 20. When the door body 2 is opened to the limit position, the remote monitoring system locks the door body 2 according to the signal of the door body 2 position sensor. At this time, the limit servo motor drives the limit rod 18 to descend and engage with the limit seat 19 to complete the locking of the door body 2.

[0095] In the present invention, the manual electric door locking device includes a connecting rod 15, a locking tongue 9, and other structures. A connecting rod 15 and a locking tongue 9 constitute a locking unit. Multiple locking units can be installed on the back of the door 2, either on the left or right side, depending on the actual force applied. The number of locking units can also be increased or decreased based on actual needs. All locking units are connected to the connecting rod connecting bracket 14 via a guide rod mounting base 12. Furthermore, the present invention incorporates a position sensor or travel switch on the door 2 for detecting its position.

[0096] The structure of the electric cylinder assembly is as follows, including: a door body mounting base 5, a push rod 4, an opening and closing cylinder body 6, a door body opening and closing servo motor, a first manual rocker arm, a first reducer, a gear set, and a fixed base 7. The above-mentioned gear set is used to realize the connection between the first manual rocker arm and the motor shaft of the door body opening and closing servo motor. When the first manual rocker arm is manually shaken, the motor shaft of the door body opening and closing servo motor can be driven to rotate by the gear set. The door body opening and closing servo motor is integrated with the first manual rocker arm, and the door body opening and closing servo motor has a motor output shaft. A manual rocker arm gear that rotates synchronously with the motor output shaft can be set on the motor output shaft. The first manual rocker arm is connected to the manual rocker arm gear (connected by gear meshing or key connection). In this way, in the power-off state, the motor output shaft of the door body opening and closing servo motor can be driven to rotate by shaking the first manual rocker arm, thereby completing the manual opening and closing of the door.

[0097] The structure of the door guide and servo motor driven locking device is as follows, including: a second manual rocker arm, an elevator 16, a limit servo motor, an elevator mounting base 17, a limit rod 18 and a limit seat 19. The limit rod 18 is mounted on the elevator mounting base 17 through a screw rod 20 and is retractable. When the door body 2 opens to the limit position, it is limited by the limit seat 19 (the limit seat 19 can be a structure that protrudes, is flush with, or is sunken relative to the ground, with the preferred structure being a protruding relative to the ground, so that when the door body 2 is opened, it can be offset against the door body 2 to achieve the opening limit of the door body 2). The limit servo motor drives the screw rod 20 to descend, and the screw rod 20 drives the limit rod 18 to descend and insert into the limit seat 19 until the bottom, and the limit operation is completed.

[0098] The main innovations of the present invention are:

[0099] 1) High-precision positioning and fast response. The electric cylinder structure adopts advanced servo control system and driver, which can make the vertical rotary door electric cylinder opening and closing device achieve high-precision positioning and fast response speed, ensuring that the protective door can be quickly closed in an emergency.

[0100] 2) Select high-efficiency motors and optimized transmission systems to improve energy conversion efficiency, reduce energy consumption, and provide sufficient driving force and torque.

[0101] 3) A modular design divides the vertical rotary door electric cylinder opening and closing system into multiple independent modules, facilitating installation, commissioning, and maintenance. Simple and reliable connections between modules enhance system reliability and maintainability. The vertical rotary door electric cylinder opening and closing system is easy to maintain. The simple structure and lack of complex components such as hydraulic circuits reduce maintenance difficulty and cost. Furthermore, the use of standardized interfaces and accessories facilitates repair and replacement.

[0102] 4) Zero emissions and low noise: The vertical rotary door electric cylinder opening and closing device uses electricity as its power source, eliminating the need for hydraulic oil or other media, achieving zero emissions and low noise operation, meeting environmental requirements. The use of high-efficiency motors and transmission systems reduces energy consumption and improves energy efficiency.

[0103] Compared with the prior art, the present invention has the following advantages:

[0104] 1. The opening and closing drive of door body 2 is driven by an electric cylinder structure, which has a small layout space and a large opening and closing torque, and is suitable for the use characteristics and layout requirements of protective doors in subway civil air defense projects;

[0105] 2. The vertical rotary door body electric cylinder opening and closing device has a simple structure, which reduces the complexity of maintenance and management. Compared with the hydraulic drive system, the vertical rotary door body electric cylinder opening and closing device does not require regular replacement of hydraulic oil, cleaning of oil circuits and maintenance of hydraulic components, which reduces maintenance costs and workload. It is a solution that conforms to environmental protection and modern management.

[0106] 3. Each device in the system is driven by a servo motor (such as the door opening and closing servo motor, locking servo motor, and limit servo motor). When the power is cut off in an emergency, the servo motor will automatically release the brake. At this time, relevant operations can be performed manually, and the system will not generate additional opening and closing resistance.

[0107] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
