Description

Technical Field

[0001] This invention relates to the field of elevator technology, specifically to an anti-collision electromechanical integrated structure for a platform elevator and its implementation method. The aim is to provide collision warnings for transporting objects that are too high through a unique mechanical structure and electrical coordination, and to stop or return the elevator in time to ensure the safety of the transport components, elevator components, and passengers. Background Technology

[0002] Platform elevators are widely used in high-end residential areas such as villas, serving not only as passenger transport but also frequently for transporting small parts. However, these elevators often lack top protection in their design, leading to a series of safety hazards.

[0003] When the height of an object to be transported exceeds the elevator's top floor design height, if there is insufficient space at the top floor, the object may collide with the top of the shaft when the elevator stops. Such an impact could not only damage the object itself and elevator components, but also pose a threat to the safety of passengers or operators.

[0004] Furthermore, because platform elevators have no obstruction at the top, the height of objects allowed to enter is typically no more than the height of the elevator doors (approximately 2 meters), which is less than the total height of the elevator. Therefore, these objects usually do not hit the top when the elevator is running normally to the top floor. However, if an object enters the elevator at an angle through the doors, its height may exceed the top of the elevator shaft. In this case, when the elevator reaches the top floor, the object could potentially hit the top of the shaft, causing property damage or personal injury.

[0005] To address these issues, an anti-collision electromechanical structure needs to be designed to prevent objects from hitting the top of the shaft when transporting objects at excessive heights, thereby ensuring the safe operation of the elevator and the personal safety of passengers. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the above-mentioned background technology and provide an anti-top-collision electromechanical integrated structure for a platform elevator and its implementation method, so as to solve the collision problem that may occur when transporting excessively tall objects in a platform elevator without top protection, and ensure the safety and stability of elevator operation.

[0007] The technical solution of this invention is: an anti-collision electromechanical integrated structure for a platform elevator, comprising: a limit switch, an upper bracket, a compression spring, a lower bracket, a compressible impact top, a control system, an audible and visual alarm, a component mounting bracket, a shaft beam light curtain, and an aluminum alloy shaft frame; the aluminum alloy shaft frame is used to fix the platform elevator and install related components. Two sets of upper and lower brackets are respectively provided at the top of the aluminum alloy shaft frame, and two compression springs are respectively provided between each set of upper and lower brackets. The limit switch consists of a limit switch mounting bracket and a limit switch swing wheel. The limit switch mounting bracket is set on the upper bracket, and the limit switch swing wheel is located above the lower bracket. A compressible impact top is connected below the lower bracket, and a component mounting bracket is provided below the compressible impact top. The control system and the audible and visual alarm are respectively provided on the component mounting bracket. A shaft beam light curtain is provided below the component mounting bracket, and the shaft beam light curtain is installed on both sides of the aluminum alloy shaft frame.

[0008] The shaft-mounted light curtain consists of a shaft-mounted light curtain transmitter, a shaft-mounted light curtain receiver, a shaft-mounted light curtain connecting line, and a shaft-mounted light curtain controller. The shaft-mounted light curtain transmitter is located below the component mounting bracket and is connected to the shaft-mounted light curtain receiver via the shaft-mounted light curtain connecting line and the shaft-mounted light curtain controller. The shaft-mounted light curtain transmitter and the shaft-mounted light curtain receiver are at the same horizontal position.

[0009] The control system is connected to the elevator traction machine, the shaft light curtain, the audible and visual alarm, the limit switch, and the compressible impact top via circuits.

[0010] A method for implementing an anti-top-touch electromechanical integrated structure for a platform elevator, the method comprising the following steps:

[0011] (1) When the platform elevator is running, the shaft beam light curtain continuously performs infrared detection on the top area. When an object is detected blocking the infrared light, it is considered that an object of too high has intruded and a pulse signal is immediately input to the control system.

[0012] (2) When the control system receives the pulse signal from the beam light curtain in the shaft, it immediately turns on the power of the sound and light alarm, so that the sound and light alarm emits light and sound to remind the movers to adjust the position of the object that is too high in the platform, and passively prevent the object from hitting the top of the shaft; at the same time, the control system immediately stops the elevator quickly to actively prevent the object from hitting the top of the shaft.

[0013] (3) Because there are too tall objects in the platform, the elevator platform cannot continue to move upward. After the elevator stops running, the control system cancels all registered floors and automatically returns to the next floor where the door can be opened. After reaching the leveling area, it opens the door and stops the sound and light alarm, waiting for the passenger to move the too tall object out of the elevator.

[0014] (4) In certain situations, such as when transporting transparent objects that prevent the infrared detector of the shaft light curtain from detecting them, or when the elevator is traveling at a high speed and there is a large inertial distance when the light curtain detects the elevator stopping, the compressible impact top can reduce the loss to a greater extent. When an object passes through the shaft light curtain and hits the compressible top, the spring of the compressible top will cushion the impact on the object, preventing excessive force from damaging the object or the top. At this time, the control system will handle the situation according to the following states:

[0015] If the light curtain has detected an object and the elevator decelerates and stops, but still comes into contact with the impact-prone compression top due to the deceleration distance, and if the limit switch on the upper part of the compression top does not activate at this time, the elevator will return to the nearest floor with an openable door after the light curtain detects an object.

[0016] If the light curtain does not detect an object coming into contact with the compressible top by the elevator itself, and if the limit switch on the upper part of the compressible top does not activate when the elevator stops, the elevator will stop at the current position, and the passenger will decide how to handle the situation.

[0017] Regardless of whether the light curtain detects an object, when the object touches the compressible top and the limit switch at the top activates, the limit switch immediately sends a pulse signal to the control system. Upon receiving the signal, the control system immediately performs an emergency stop at the current position, cancels all registered floors, and records a fault. At the same time, it activates the power supply to the audible and visual alarm, causing the alarm to emit light and sound to remind the movers to adjust the position of excessively tall objects in the platform, passively preventing objects from hitting the top of the shaft.

[0018] After the elevator stops running, the control system sends a command to automatically return to the next floor where the door can be opened. Once it reaches the leveling area, it opens the door automatically and stops the audible and visual alarms, waiting for passengers to move the excessively tall objects out of the elevator.

[0019] At this point, since there is no object in contact with the compressible top, the spring force will automatically push the top back, causing the limit switch to return to its original state. The control system also checks whether the limit switch has returned to its original position. If it has, the fault is cleared and the elevator returns to a working state. If it has not, it proves that the impact force was too large and may cause damage to the top of the shaft. In this case, the fault is not cleared, the elevator cannot continue to be used, and it must be repaired and maintained by professionals.

[0020] Compared with existing technologies, this invention achieves timely warning of objects that are too high through the shaft light curtain and audible and visual alarm, reminding passengers to pay attention to safety; through the compressible impact top and limit switch, it achieves timely detection and response to impact events, effectively avoiding hard contact between objects and the shaft top, protecting the elevator and transportation components; the control system can stop the elevator operation in time and make reasonable return-to-floor instructions based on the warning and impact signals, ensuring the personal safety of passengers.

[0030] A method for implementing an anti-top-touch electromechanical integrated structure for a platform elevator, the method comprising the following steps:

[0031] (1) When the platform elevator is running, the shaft beam light curtain continuously performs infrared detection on the top area. When an object is detected blocking the infrared light, it is considered that an object of too high has intruded and a pulse signal is immediately input to the control system.

[0032] (2) When the control system receives the pulse signal from the beam light curtain in the shaft, it immediately turns on the power of the sound and light alarm, so that the sound and light alarm emits light and sound to remind the movers to adjust the position of the object that is too high in the platform, and passively prevent the object from hitting the top of the shaft; at the same time, the control system immediately stops the elevator quickly to actively prevent the object from hitting the top of the shaft.

[0033] (3) Because there are too tall objects in the platform, the elevator platform cannot continue to move upward. After the elevator stops running, the control system cancels all registered floors and automatically returns to the next floor where the door can be opened. After reaching the leveling area, it opens the door and stops the sound and light alarm, waiting for the passenger to move the too tall object out of the elevator.

[0034] (4) In certain situations, such as when transporting transparent objects that prevent the infrared detector of the shaft light curtain from detecting them, or when the elevator is traveling at a high speed and there is a large inertial distance when the light curtain detects the elevator stopping, the compressible impact top can reduce the loss to a greater extent. When an object passes through the shaft light curtain and hits the compressible top, the spring of the compressible top will cushion the impact on the object, preventing excessive force from damaging the object or the top. At this time, the control system will handle the situation according to the following states:

[0035] If the light curtain has detected an object and the elevator decelerates and stops, but still comes into contact with the impact-prone compression top due to the deceleration distance, and if the limit switch on the upper part of the compression top does not activate at this time, the elevator will return to the nearest floor with an openable door after the light curtain detects an object.

[0036] If the light curtain does not detect an object coming into contact with the compressible top by the elevator itself, and if the limit switch on the upper part of the compressible top does not activate when the elevator stops, the elevator will stop at the current position, and the passenger will decide how to handle the situation.

[0037] Regardless of whether the light curtain detects an object, when the object touches the compressible top and the limit switch at the top activates, the limit switch immediately sends a pulse signal to the control system.

Once it reaches the leveling area, it opens the door automatically and stops the audible and visual alarms, waiting for passengers to move the excessively tall objects out of the elevator.

[0039] At this point, since there is no object in contact with the compressible top, the spring force will automatically push the top back, causing the limit switch to return to its original state. The control system also checks whether the limit switch has returned to its original position. If it has, the fault is cleared and the elevator returns to a working state. If it has not, it proves that the impact force was too large and may cause damage to the top of the shaft. In this case, the fault is not cleared, the elevator cannot continue to be used, and it must be repaired and maintained by professionals.
