Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of elevator equipment, in particular to an elevator rescue device and an elevator. BACKGROUND

[0002] Elevator is a device frequently used in daily life, and the high frequency of use is prone to elevator trapping failure. Among the elevator trapping failures, there is a special load condition, that is, the load on the car side and the counterweight side is consistent. In this condition, rescue is more difficult due to the equal load on both sides.

[0003] When the elevator trapping failure of the equal load condition occurs, if the elevator is equipped with a hand wheel for turning, manual turning is needed to move the car for rescue, which is complicated to operate and has low automation. Moreover, the elevator without machine room basically cannot be equipped with a hand wheel for turning. For the elevator without a hand wheel for turning, it is necessary to rely on manual pulling of the traction rope or the use of hoisting equipment such as hand-operated hoist to move the elevator car. However, the configuration of hoisting equipment will result in high cost of the elevator and more complex installation of the elevator. Therefore, the current elevator rescue device has the defects of complicated operation and high cost in the equal load condition. CONTENT OF THE UTILITY MODEL

[0037] See Figure 1 and Figure 2This diagram illustrates the structure of an elevator rescue device according to an embodiment of this application. The elevator rescue device and elevator include a control mechanism 100, a drive mechanism 200, and a clamping mechanism 300. The control mechanism 100 is electrically connected to the traction mechanism 20 of the elevator. The drive mechanism 200 is mounted on the load-bearing beam 24 of the traction mechanism 20 and is electrically connected to the control mechanism 100. The drive mechanism 200 is also connected to the traction sheave 22 of the traction mechanism 20 via a transmission connection. The clamping mechanism 300 includes a first clamp 310 and a second clamp 320. Both the first clamp 310 and the second clamp 320 are mounted on the load-bearing beam 24. The first clamp 310 is used to clamp or release the traction rope 21 extending from one end of the traction sheave 22, and the second clamp 320 is used to clamp or release the traction rope 21 extending from the other end of the traction sheave 22. Both the first clamp 310 and the second clamp 320 are electrically connected to the control mechanism 100.

[0038] In one exemplary embodiment, such as Figure 2 As shown, the first clamp 310 is used to clamp or release the traction rope 21 between the car 10 and the traction sheave 22, and the second clamp 320 is used to clamp or release the traction rope 21 between the counterweight mechanism 30 and the traction sheave 22.

[0039] The elevator rescue device described in this application embodiment electrically connects the control mechanism 100 to the traction mechanism 20, thereby enabling the control mechanism 100 to obtain the state of the traction mechanism 20. The drive mechanism 200 is connected to the traction sheave 22 for transmission, and the drive mechanism 200 is used to drive the traction sheave 22 to rotate. The first clamp 310 clamps or releases the traction rope 21 at one end of the traction sheave 22, and the second clamp 320 clamps or releases the traction rope 21 at the other end of the traction sheave 22. The first clamp 310 and the second clamp 320 are used to ensure that the traction rope 21 will not move unexpectedly. The control mechanism 100 can control the operation of the drive mechanism 200, the first clamp 310 and the second clamp 320. When the control mechanism 100 detects that the elevator is trapped, the control mechanism 100 controls the drive mechanism 200 to operate. At this time, the first clamp 310 and the second clamp 320 cooperate to release the clamp on the traction rope 21, so that the drive mechanism 200 drives the traction wheel 22 to rotate, thereby moving the car 10 to the leveling and unlocking area through the traction rope 21 for further rescue.

[0040] The elevator rescue device described in this application embodiment has a control mechanism 100 that can control the drive mechanism 200 to move the car 10 when a fault occurs, without the need for manual operation. It can also be adapted to different types of elevators, is easy to install, and has strong versatility. The control mechanism 100 can acquire a variety of fault signals, so it can rescue a wide range of fault conditions. It has the advantages of simple operation and low cost.

[0041] In some embodiments, the control mechanism 100 includes a power supply module, a control module, a detection module, and an energy storage module. The power supply module is electrically connected to the power supply of the elevator and is also electrically connected to the energy storage module. The detection module is electrically connected to the traction host 23 of the traction mechanism 20. The detection module and the drive mechanism 200 are both electrically connected to the control module, and both the detection module and the control module are electrically connected to the energy storage module.

[0042] The control mechanism 100 in this embodiment is the core of the elevator rescue device for signal reception and signal transmission. The power module obtains power from the elevator and provides power to the elevator rescue device. The detection module acquires elevator entrapment signals, including but not limited to alarm signals inside the car 10, traction motor 23 power-on signals, control cabinet door lock signals, and safety circuit signals. The control module sets different operating modes based on different elevator entrapment signals obtained by the detection module and outputs control signals to the drive mechanism. The energy storage module stores electrical energy during normal operation and provides power to the elevator rescue device when the elevator loses power.

[0043] In an exemplary embodiment, the power module includes an input circuit, a conversion circuit, a control circuit, and an output circuit. The input circuit connects to an external power source and performs preliminary filtering and processing on the input power to reduce electromagnetic interference and noise. The conversion circuit typically employs switching power supply technology to convert the input AC or DC power into the required DC voltage. Common conversion circuit topologies include flyback, forward, push-pull, half-bridge, and full-bridge, with different topologies suitable for different power ranges and application scenarios. The control circuit controls the operation of the conversion circuit, achieving precise adjustment and stable control of the output voltage. Through a feedback mechanism, the control circuit compares the output voltage with a set reference voltage and adjusts the on-time and frequency of the switching transistors based on the error signal, thereby maintaining a stable output voltage. The output circuit further filters and regulates the converted DC voltage to provide a clean and stable DC power supply to the load. Simultaneously, the output circuit may also include overcurrent protection and overvoltage protection circuits to ensure the safe operation of the load.

[0044] Furthermore, the control module includes a microprocessor, memory, input / output interfaces, and communication circuits. The control module uses these components to control and coordinate operations, ensuring the efficiency and safety of the rescue work.

[0045] Furthermore, the detection module includes sensors, signal conditioning circuits, data acquisition circuits, and communication interfaces. The detection module uses these components to monitor various status parameters and operating conditions of the elevator in real time, so as to detect abnormalities in a timely manner and take corresponding measures.

[0046] Furthermore, the energy storage module is a battery. Under normal conditions, the power module charges the battery. When the elevator experiences a power outage, the battery can provide power to the entire elevator rescue device, thereby ensuring the stable operation of the elevator rescue device.

[0047] In one exemplary embodiment, the control module can set two operating modes based on the elevator's preset parameters: a normal movement mode and a high-height movement mode. The normal movement mode is set to multiple inching movements, meaning the car 10 moves 10cm at a time and then stops, repeating this cycle until it reaches the leveling and unlocking area. The high-height movement mode is primarily for special situations where the distance between floors is large and rescue operations are possible. It is set to start slowly, then move at a constant speed, and finally slowly approach the leveling point, aiming to ensure comfortable movement while maximizing rescue time. Of course, the control module can automatically select between these two modes based on the car 10's position and the elevator's parameters.

[0048] In an optional embodiment, the control mechanism 100 further includes a remote IoT module electrically connected to the control module. Furthermore, a camera is installed inside the car 10. By configuring the remote IoT module and the camera, remote online rescue operations and observation of the situation of personnel inside the car 10 can be realized, making rescue operations more stable and intelligent.

[0049] In an optional embodiment, such as Figure 1 and Figure 2 As shown, the drive mechanism 200 includes a drive wheel 210, a mounting frame 220, and a drive unit 230. The mounting frame 220 is used to mount the load-bearing beam 24. The drive wheel 210 is movably mounted on the mounting frame 220. The drive unit 230 is mounted on the mounting frame 220 and is electrically connected to the control mechanism 100. The power output end of the drive unit 230 is connected to the drive wheel 210, and the drive wheel 210 is used to connect to the traction sheave 22. The drive unit 230 can obtain electrical energy from a power module or an energy storage module. By setting the mounting frame 220 on the load-bearing beam 24, the drive wheel 210 is movably mounted on the mounting frame 220, and the drive wheel 210 and the traction sheave 22 are rotatably connected. When the control module starts the drive unit 230, the drive unit 230 can drive the drive wheel 210 to rotate, which in turn drives the traction wheel 22 to rotate. The rotation of the traction wheel 22 then drives the traction rope 21 on it to move, thereby moving the car connected to the traction rope 21 to the floor.

[0050] In an optional embodiment, such as Figure 2As shown, the drive mechanism 200 also includes an elastic element 240. The drive wheel 210 is radially movably arranged along the traction sheave 22. One end of the elastic element 240 is connected to the drive wheel 210, and the other end is connected to the mounting frame 220. The drive wheel 210 and the traction sheave 22 are movably connected, and the drive wheel 210 can move radially along the traction sheave 22. By providing the elastic element 240, which is connected to the mounting frame 220 and the drive wheel 210, the elastic force of the elastic element 240 pushes the drive wheel 210 to abut against the traction sheave 22, enhancing the stability and reliability of the drive wheel 210 during operation. When the drive wheel 210 and the traction sheave 22 are driven by friction, the greater the elastic force of the elastic element 240, the greater the wheel pressure of the drive wheel 210 on the traction sheave 22, resulting in a better frictional connection between the drive wheel 210 and the traction sheave 22, and improving the stability of use.

[0051] In an exemplary embodiment, the mounting bracket 220 is provided with a sliding groove, the extension direction of which is consistent with the radial direction of the traction wheel 22. The drive wheel 210 is movably disposed in the sliding groove. The elastic element 240 is a spring, and the two ends of the spring are respectively connected to the drive wheel 210 and the mounting bracket 220, thereby pushing the drive wheel 210 to abut against the traction wheel 22.

[0052] In an optional embodiment, the clamping mechanism 300 further includes a first pressure sensor and a second pressure sensor. The first pressure sensor is mounted on the first clamp 310 and electrically connected to the control module. The second pressure sensor is mounted on the second clamp 320 and electrically connected to the control module.

[0053] This embodiment uses a first pressure sensor in the first gripper 310 and a second pressure sensor in the second gripper 320 to obtain the magnitude of the first tension of the traction rope on the car side and the magnitude of the second tension of the traction rope 21 on the counterweight side. Based on the magnitude of the first and second tensions, the system can determine whether to move the car 10 upwards or downwards. When the tension on the car side is greater than the tension on the counterweight side, the drive mechanism 200 is controlled to move the car 10 downwards to the floor level. When the tension on the car side is less than the tension on the counterweight side, the drive mechanism 200 is controlled to move the car 10 upwards to the floor level. This reduces the energy output of the elevator rescue device, ensuring the smooth completion of the rescue operation of the car 10 and offering the advantage of high reliability.

[0054] In an exemplary embodiment, the procedure for rescuing the car by moving upwards is as follows: First, the drive mechanism 200 is energized, the second clamp is released, and then the first clamp is released, allowing the car 10 to move slowly, thus preventing the car 10 from sliding backwards and avoiding the passengers experiencing a feeling of falling. When approaching the leveling unlock area, the drive mechanism 200 decelerates to a stop, the first clamp first clamps the traction rope 21, then the second clamp clamps the traction rope 21, and finally the drive mechanism 200 is de-energized. This ensures that the traction rope 21 does not slacken or disengage, and the car 10 moves slowly and stably. The reverse procedure is followed when moving in the opposite direction.

[0055] In an optional embodiment, such as Figure 1 and Figure 2 As shown, the elevator rescue device also includes a positioning mechanism 400, which includes a transmitter 410 and a receiver 420. The transmitter 410 is installed on the load-bearing beam 24, and the receiver 420 is installed on the elevator car 10. The transmitter 410 and receiver 420 are correspondingly arranged, and the receiver 420 is electrically connected to the control module. In other embodiments, the transmitter 410 can also be installed on the car 10, and the receiver 420 can be installed on the load-bearing beam 24.

[0056] Under normal circumstances, the leveling unlocking area can be identified by marking lines on the traction rope 21 or by an audio-visual device for the unlocking area, and then the car 10 is moved to the leveling unlocking area. However, the marking lines on the traction rope 21 will wear out and become unclear over time, and the audio-visual device for the unlocking area cannot provide a display when the elevator is powered off, making it impossible to identify the unlocking area. In this embodiment, a transmitter 410 and a receiver 420 are respectively installed on the car 10 and the load-bearing beam 24. The position of the car 10 is obtained through the transmitter 410 and the receiver 420, thereby accurately moving the car 10 to the leveling unlocking area, which has the advantages of high identification accuracy and high reliability.

[0057] In one exemplary embodiment, such as Figure 2 As shown, the transmitter 410 is connected to the load-bearing beam 24 via a mounting rod 430.

[0058] In an optional embodiment, such as Figure 3 As shown, the drive wheel 210 has a gear on its circumference, which is used to mesh with the traction wheel 22. When the traction wheel 22 is a gear, by setting the drive wheel 210 as a gear, the drive wheel 210 and the traction wheel 22 can be meshed and connected, thereby driving the traction wheel 22 to rotate.

[0059] In another embodiment, such as Figure 4As shown, the outer surface of the drive wheel 210 is provided with multiple rubber strips spaced along the axis. These rubber strips are used for frictional connection with the traction sheave 22. By providing rubber strips on the drive wheel 210, the friction between the drive wheel 210 and the traction sheave 22 is increased, making the drive wheel 210 suitable for most traction sheaves 22, thus having the advantage of good applicability.

[0060] In other embodiments, such as Figure 5 As shown, the drive wheel 210 is equipped with a permanent magnet, and the drive wheel 210 is frictionally connected to the traction wheel 22. By equipping the drive wheel 210 with a permanent magnet, a magnetic attraction force is generated between the drive wheel 210 and the metal traction wheel 22, thereby enhancing the tightness of the connection between the drive wheel 210 and the traction wheel 22.

[0061] In an optional embodiment, the control mechanism 100 includes a housing with a receiving cavity and a battery cavity. The power module, control module, and detection module are all housed in the receiving cavity, while the energy storage module is detachably housed in the battery cavity. By providing the receiving cavity and battery cavity within the housing, the different modules of the control mechanism 100 can be fitted together and installed inside the housing, preventing environmental factors such as dust from affecting the functions of the power module, control module, and detection module. Furthermore, the energy storage module can be easily removed from the housing for convenient replacement.

[0062] On the other hand, embodiments of this application also provide an elevator, such as Figure 1 and Figure 2 As shown, the elevator includes a traction mechanism 20, a car 10, a counterweight mechanism 30, and an elevator rescue device as described in any of the above embodiments. The car 10 is movably disposed in the elevator shaft, and the counterweight mechanism 30 is movably disposed on one side wall of the elevator shaft. The traction mechanism 20 includes a traction rope 21, a traction sheave 22, a traction host 23, and a load-bearing beam 24. The load-bearing beam 24 is installed at the top of the elevator shaft, and the traction host 23 is installed on the load-bearing beam 24. The power output end of the traction host 23 is connected to the traction sheave 22. One end of the traction rope 21 is connected to the car 10, and the other end of the traction rope 21 passes around the traction sheave 22 and is connected to the counterweight mechanism 30. The elevator rescue device is installed on the traction mechanism 20.

[0063] The elevator described in this application embodiment, by installing an elevator rescue device, enables the control mechanism 100 to control the drive mechanism 200 to move the car 10 when a entrapment fault occurs in the elevator, without the need for manual operation. Moreover, it can be adapted to different types of elevators, is simple to install, and has strong versatility. The control mechanism 100 can acquire a variety of fault signals, so it can rescue people in many fault situations. It has the advantages of simple operation and low cost.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
