Description

Technical Field

[0001] The present invention relates to the technical field related to elevator rescue equipment, and in particular to an emergency opening device for a quick rescue passenger elevator car frame and a use method thereof. Background Art

[0002] During the operation of an elevator, passengers are often trapped in the elevator car due to equipment aging factors such as mechanical wear, electrical failure, and control system abnormalities, or external environmental influences such as power grid fluctuations, sudden power outages, and natural disasters. Traditional elevator rescue methods mainly rely on professional rescuers carrying special triangular keys, crowbars and other tools to open the elevator floor doors and car doors to rescue trapped passengers. This not only requires extremely high professional skills from rescuers, but is also subject to objective factors such as traffic conditions and rescue distances, resulting in a generally long rescue response time. Trapped passengers are very likely to suffer from physical and psychological discomfort such as shortness of breath, panic and anxiety due to problems such as oxygen consumption in a confined space and excessive psychological pressure. Therefore, there is a special need for an emergency opening device and a method for using it for quickly rescuing a passenger elevator car frame.

[0003] Chinese patent CN118495302B published on October 11, 2024 discloses an elevator car with an emergency rescue device. The distance between the entire emergency rescue device and the safety passage is shortened by a folding frame assembly and a telescopic ladder assembly, so that people can enter the safety passage along the telescopic ladder assembly, avoiding the danger of height fear caused by the long distance between the car body and the elevator shaft. The entire emergency rescue device can be set on the side wall of the elevator car, which is convenient for people of different heights to use and makes the entire emergency rescue device storable. However, the elevator car with the emergency rescue device is heavily dependent on external power supply and complex system response when in use. Once a power outage, circuit failure or hydraulic system leakage occurs, the emergency switch will not be able to open. The start function will not work properly, resulting in trapped passengers unable to be rescued in time. In actual use, the elevator operating environment is complex and changeable, and emergencies such as power outages and equipment failures occur from time to time, making it difficult to ensure the timeliness and reliability of rescue. It is only equipped with a single contact anti-pinch device, and the anti-pinch function will be triggered only when an obstacle is in direct contact with the elevator door. It lacks early warning capabilities. During the closing process of the elevator door, if passengers or objects fail to avoid in time, pinching accidents are very likely to occur. It is impossible to perform real-time and sensitive monitoring of obstacles between the elevator doors, making it difficult to fully ensure passenger safety and unable to effectively buffer external impact forces. After long-term use, the elevator door may have problems such as reduced sealing and structural damage, which reduces the reliability and service life of the device and increases maintenance costs and safety risks. Summary of the Invention

[0004] The purpose of the present invention is to provide an emergency opening device and a method of use for a quick rescue passenger elevator car frame, so as to solve the problem that the existing elevator car with emergency rescue device proposed in the above background technology is heavily dependent on external power supply and complex system response when in use. Once a power outage, circuit failure or hydraulic system leakage occurs, the emergency opening function will not work normally, resulting in trapped passengers unable to be rescued in time. In actual use, the elevator operating environment is complex and changeable, and emergencies such as power outages and equipment failures occur from time to time, making it difficult to ensure the timeliness and reliability of rescue. It is only equipped with a single contact anti-pinch device, and the anti-pinch function will only be triggered when an obstacle is in direct contact with the elevator door. It lacks early warning capability. During the closing process of the elevator door, if the passenger or object fails to avoid in time, a pinching accident is very likely to occur. It is impossible to perform real-time and sensitive monitoring of obstacles between the elevator doors, making it difficult to fully ensure passenger safety and unable to effectively buffer external impact forces.

[0014] An emergency opening device for a quick rescue passenger elevator car frame and a method for using the device include the following steps: Step 1: Component Manufacturing: Frame and foundation component fabrication: High-strength metal materials are used to manufacture the frame through cutting and welding processes to ensure that its dimensional accuracy and structural strength meet the load-bearing requirements of the elevator car frame. Mounting slots are reserved at the bottom of the frame for fixing electromagnetic rails. The electromagnetic rails are fixedly installed in the mounting slots at the bottom of the frame and tightened with bolts. Electrical connections are debugged to ensure that the electromagnetic rails can stably generate electromagnetic force to drive the elevator car to operate smoothly. The elevator car is manufactured by stamping and welding metal sheets according to the design dimensions, and mounting holes are reserved on the outside of the car for installing the left and right elevator doors. Manufacturing of elevator doors and related components: Use metal sheets to make the left elevator door, and accurately process through holes and snap-in grooves on the outside. The size of the through holes must be adapted to the reset column. The snap-in groove is used to cooperate with the silicone pad. Similarly, make the right elevator door, and process snap-in grooves two to prepare for the subsequent installation of silicone pad two. Use highly elastic silicone material to make silicone pads one and two through mold injection molding, and integrally form snap-in columns one and two on the outside of the silicone pad to ensure that the snap-in columns are firmly connected to the silicone pad. Make the right and left sensing doors separately, install mounting base one on the outside of the right sensing door, and fix the infrared sensing lamp. Install mounting base two on the outside of the left sensing door, fix the receiver, and fix the sensor on the sensing base. The fixed roller is installed on the fixed base. The rotating rod can be flexibly rotatably installed on the outside of the fixed roller. The connecting block and the trigger rod are fixed on the outside of the rotating rod in turn, and the contact position of the rotating rod and the arc seat is adjusted to ensure good contact and smooth rotation. Use metal materials to make an emergency box, and design a reasonable space layout inside the box for installing support rods, hooks and rings and other components; Step 2: Component assembly: Elevator door assembly: Fix silicone pad 1 to the first clamping slot of the left elevator door through the first clamping column, and fix silicone pad 2 to the second clamping slot of the right elevator door through the second clamping column. Install the induction anti-pinch assembly inside the right elevator door, so that the right induction door and the right elevator door fit tightly together. Install the left induction door and related components inside the left elevator door, ensuring that the infrared induction lamp and the receiver are accurately positioned. The two sets of induction anti-pinch assemblies are symmetrically distributed about the vertical center line of the frame. Install the emergency opening assembly on the outside of the frame, so that the emergency box is firmly fixed, the hook ring and the lock hook are in normal cooperation, and the limit seat and the fixing plate are fixedly connected to the left induction door to ensure that the emergency opening assembly and the induction anti-pinch assembly form a linkage structure. Overall assembly: Install the elevator car with the elevator doors and related components installed on the electromagnetic slide rails inside the frame. Adjust the position of the elevator car to ensure that it runs smoothly on the electromagnetic slide rails, and that the left and right elevator doors open and close smoothly and fit tightly with the car. Step 3: Debugging and testing: Debugging the sensor anti-pinch function: Start the elevator operation program, simulate the elevator door closing process, place obstacles of different sizes and shapes between the elevator doors, test the sensitivity of the infrared sensor light and the receiver, and the mechanical linkage response of the sensor, rotating rod, trigger rod and other components, to ensure that the elevator door can quickly stop and open in the opposite direction when an obstacle is detected. Record the debugging data and adjust or replace any components that do not meet the requirements. Emergency opening function test: In emergency situations such as simulated power outages and control system failures, manually operate the emergency opening assembly to disengage the lock hook from the hook ring. Observe the movement of the reset spring driving the connecting rod, rotating connecting rod, and other components, as well as the reset rod and reset column opening the left elevator door. Test multiple times to ensure that the emergency opening operation is simple and reliable, and that the opening time meets the design requirements. If any fault occurs, promptly investigate and repair it. Operation stability test: Run the elevator under different load and speed conditions to test the guiding and shock-absorbing performance of the electromagnetic slide rail on the elevator car, as well as the sealing and stability of the elevator door during operation. Check whether the connections between the various components are firm, and whether there is any looseness or abnormal noise. Any problems found will be dealt with in a timely manner to ensure that the entire emergency opening device can operate stably and reliably.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The emergency opening device and method for using a rapid-rescue passenger elevator car frame of the present invention, by providing an emergency opening assembly, eliminates the need for external power supplies or complex system responses. Rescuers only need to operate the lock hook to disengage the shackle ring. The reset spring activates the connecting rod, rotating connecting rod, and other components, thereby rapidly opening the left elevator door via the reset rod and reset column. This significantly shortens rescue time, especially in extreme situations such as power outages, as the emergency opening assembly can still operate stably, ensuring timely rescue. 2. The emergency opening device and method for the rapid rescue passenger elevator car frame of the present invention utilizes an inductive anti-pinch assembly. The infrared sensor light and receiver work together to monitor obstacles between elevator doors in real time, providing enhanced sensitivity and early warning capabilities. Furthermore, the tilting structure composed of the fixed base, sensing base, and sensor, in conjunction with components such as a rotating rod and a trigger lever, not only rapidly stops the elevator door from closing upon detecting an obstacle, but also promptly triggers an emergency response through mechanical linkage, further ensuring passenger safety. The multi-layered and multi-faceted anti-pinch design more comprehensively prevents the risk of passenger injuries. 3. The emergency opening device and use method of the quick rescue passenger elevator car frame of the present invention have better guiding and shock-absorbing performance, reducing the impact of the shaking of the elevator operation on various components. Through the cooperation of silicone pad 1 and silicone pad 2 on the outside of the left elevator door and the right elevator door with the clamping column 1 and clamping column 2, as well as the design of the clamping groove 1 and clamping groove 2, not only the sealing of the elevator door is enhanced, but also the external impact force can be buffered to a certain extent, the durability of the overall structure is improved, and the reliability and service life of the device are significantly improved.

All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention. Example 1

[0019] See also Figure 1-10 The present invention provides a technical solution: an emergency opening device for a quick rescue passenger elevator frame and a method of use, comprising a frame 1, an electromagnetic slide rail 2 fixedly installed at the bottom of the interior of the frame 1, an elevator car 3 arranged inside the frame 1, a left elevator door 4 arranged on the outside of the elevator car 3, a through hole 5 opened on the outside of the left elevator door 4, a clamping groove 6 opened on the outside of the left elevator door 4, a silicone pad 7 movably installed on the outside of the left elevator door 4, a clamping column 8 fixedly installed on the outside of the silicone pad 7, a right elevator door 9 arranged on the outside of the elevator car 3, a clamping groove 2 opened on the outside of the right elevator door 9, a silicone pad 2 11 movably installed on the outside of the right elevator door 9, a clamping column 2 12 fixedly installed on the outside of the silicone pad 2 11, an induction anti-pinch component 13 arranged inside the right elevator door 9, and an emergency opening component 14 arranged inside the left elevator door 4.

[0020] The induction anti-pinch assembly 13 includes a right induction door 1301, which is arranged inside the right elevator door 9. A mounting seat 1302 is fixedly installed on the outside of the right induction door 1301, and an infrared induction lamp 1303 is fixedly installed on the outside of the mounting seat 1302. A left induction door 1304 is arranged inside the left elevator door 4. A mounting seat 2 1305 is fixedly installed on the outside of the left induction door 1304, and a receiver 1306 is fixedly installed on the outside of the mounting seat 2 1305. A fixing seat 1307 is fixedly installed on the outside of the left induction door 1304, and a sensing seat 1308 is fixedly installed on the outside of the fixing seat 1307. A sensor 1309 is fixedly installed on the outside of the sensing seat 1308, and an outer curvature seat 1310 of the fixing seat 1307 is fixedly installed on the outside of the fixing seat 1307. A fixed roller 1311 is fixedly installed on the outside of the fixed roller 1311. A rotating rod 1312 is installed on the side, and a connecting block 1313 is fixedly installed on the outside of the rotating rod 1312. A trigger rod 1314 is fixedly installed on the outside of the connecting block 1313. The left sensing door 1304 is configured in the same manner as the right sensing door 1301. By providing an induction anti-pinch component 13, the infrared sensing lamp 1303 cooperates with the receiver 1306 to monitor obstacles between the elevator doors in real time, with higher sensitivity and early warning capabilities. At the same time, the inclined structure composed of the fixed seat 1307, the sensing seat 1308, the sensor 1309, etc. cooperates with the rotating rod 1312, the trigger rod 1314 and other components. When an obstacle is detected, it can not only quickly stop the elevator door closing action, but also trigger an emergency response in time through mechanical linkage, thereby further ensuring the safety of passengers. The multi-level and multi-mode anti-pinch design can more comprehensively avoid the risk of passengers being pinched.

[0021] The fixing seat 1307, the sensing seat 1308, the sensor 1309, the radian seat 1310, the fixed roller 1311, the rotating rod 1312, the connecting block 1313 and the trigger rod 1314 are provided in two identical groups, and the two groups of the fixing seat 1307, the sensing seat 1308, the sensor 1309, the radian seat 1310, the fixed roller 1311, the rotating rod 1312, the connecting block 1313 and the trigger rod 1314 are symmetrically distributed about the vertical center line of the frame 1. By providing two sets of fixing seats 1307, the sensing seat 1308, the sensor 1309, the radian seat 1310, the fixed roller 1311, the rotating rod 1312, the connecting block 1313 and the trigger rod 1314 are symmetrically distributed about the vertical center line of the frame 1. The seat 1307, the sensing seat 1308, the sensor 1309, the arc seat 1310, the fixed roller 1311, the rotating rod 1312, the connecting block 1313 and the trigger rod 1314 can realize all-round and no-dead-angle monitoring and protection of both sides of the elevator door, so that when an obstacle appears at any position of the elevator door, the anti-pinch mechanism can be quickly triggered to avoid the safety hazards caused by the unilateral sensing blind spot, thereby improving the reliability and stability of the sensing anti-pinch component 13 and ensuring the safety of the elevator during operation.

[0022] The combination of the fixed seat 1307, the sensing seat 1308, the sensor 1309, the arc seat 1310, the fixed roller 1311, the rotating rod 1312, the connecting block 1313 and the trigger rod 1314 has an inclined structure, and the rotating rod 1312 is in contact with the arc seat 1310. By setting the combination of the fixed seat 1307, the sensing seat 1308, the sensor 1309, the arc seat 1310, the fixed roller 1311, the rotating rod 1312, the connecting block 1313 and the trigger rod 1314 to have an inclined structure, it can be precisely controlled so that the trigger rod 1314 can trigger the emergency response action more quickly and accurately. The inclined structure can better utilize the principles of gravity and mechanical leverage, reduce friction loss between components, reduce loss in energy transfer, ensure that the elevator door can stop and open quickly at the moment an obstacle is detected, and improve the response speed and reliability of the overall anti-pinch system.

[0023] Two identical groups of sensing bases 1308 and sensors 1309 are provided, and the two groups of sensing bases 1308 and sensors 1309 are symmetrically distributed about the vertical center line of the rotating rod 1312. By providing two groups of sensing bases 1308 and sensors 1309, the position and size of the obstacle can be judged more accurately, thereby more accurately controlling the movement of the elevator door. When a smaller obstacle approaches the edge of the elevator door, the two groups of sensors 1309 work together to trigger the anti-pinch mechanism in a timely and accurate manner, preventing safety accidents caused by sensing deviation, and further enhancing the reliability and safety of the sensing anti-pinch component 13.

[0024] The emergency opening assembly 14 includes an emergency box 1401, which is mounted on the outside of the frame 1. A support rod 1402 is fixedly mounted on the bottom of the emergency box 1401, a hook 1403 is fixedly mounted on the top of the support rod 1402, a lock hook 1404 is provided on the outside of the hook 1403, a connecting rod 1405 is fixedly mounted on the outside of the lock hook 1404, a return spring 1406 is fixedly mounted on the top of the connecting rod 1405, a limit seat 1407 is fixedly mounted on the top of the return spring 1406, a limit column 1408 is fixedly mounted on the bottom of the limit seat 1407, a rotating connecting rod 1409 is fixedly mounted on the outside of the connecting rod 1405, a connecting disc 1410 is fixedly mounted on the outside of the connecting disc 1410, and a rotating connecting rod 1409 is fixedly mounted on the inside of the connecting disc 1410. Shaft 1411, a fixed plate 1412 is fixedly installed on the outside of the rotating shaft 1411, a reset column 1413 is rotatably installed inside the left elevator door 4, and a reset rod 1414 is fixedly installed on the outside of the reset column 1413. The hook 1403 and the lock hook 1404 are in contact. By setting up the emergency opening component 14, there is no need to rely on an external power supply or complex system response. Rescuers only need to perform simple operations to disengage the lock hook 1404 from the hook 1403. Under the action of the reset spring 1406, the connecting rod 1405, the rotating connecting rod 1409 and other components are driven to move, and then the left elevator door 4 is quickly opened through the reset rod 1414 and the reset column 1413, which greatly shortens the rescue time. Especially in extreme cases such as power outages, the emergency opening component 14 can still operate stably to ensure timely rescue.

[0025] The limit seat 1407 is fixedly connected to the left sensing door 1304, and the fixed plate 1412 is fixedly connected to the left sensing door 1304. By setting the limit seat 1407 and the left sensing door 1304, when the elevator door cannot be controlled normally, the emergency opening component 14 can enter the emergency preparation state in advance under the triggering of the sensing anti-pinch component 13, or directly start the emergency opening program, further improving the integrity and reliability of the elevator safety protection.

[0026] The limiting column 1408 is located inside the reset spring 1406, and the rotating link 1409 is in contact with the reset rod 1414. By setting the rotating link 1409 and the reset rod 1414, it is ensured that the emergency opening component 14 can operate stably and reliably during each action, avoiding emergency opening failure due to matching errors between components.

[0027] The reset column 1413 is located inside the left elevator door 4, and a cross slot is provided on the outside of the reset column 1413. By setting the reset column 1413 inside the left elevator door 4 and a cross slot is provided on the outside of the reset column 1413, the cross slot structure can be used to open the elevator using a screwdriver from the outside to prevent slipping or loosening during the opening process, thereby ensuring the smooth progress of the emergency opening operation. Setting the reset column 1413 inside the left elevator door 4 not only ensures that it will not affect the normal opening and closing action of the elevator door during normal operation, but also facilitates quick positioning and operation in an emergency, thereby improving the efficiency of emergency rescue.

The size of the through hole 5 needs to be adapted to the reset column 1413. The clamping groove 6 is used to cooperate with the silicone pad 7 for installation. Similarly, make the right elevator door 9, and process the clamping groove 2 10 to prepare for the subsequent installation of the silicone pad 2 11. Use high-elastic silicone material to make silicone pad 1 7 and silicone pad 2 11 through mold injection molding, and integrally form the clamping column 1 8 and the clamping column 2 12 on the outside of the silicone pad to ensure that the clamping column is firmly connected to the silicone pad.
