Description

Technical Field

[0001] The present invention relates to the technical field of gas buffer type elevator shock absorbers, and specifically relates to a gas buffer type elevator shock absorber with a self-detection structure. Background Art

[0002] The self-detection structure gas buffer type elevator shock absorber is an active shock absorption device based on the gas compression principle. The air chamber and the piston rod absorb vibration energy through the compression and release of gas. The air chamber is usually filled or suddenly impacted. With the increase of high-rise buildings and the development of elevator high-speedization, the performance requirements for shock absorbers are becoming increasingly stringent. The self-detection gas buffer shock absorber not only improves the comfort of passengers, but also reduces the operation and maintenance costs by reducing the failure rate. However, the gas pressure of the existing gas buffer type elevator shock absorber cannot be automatically detected, which reduces the shock absorption safety.

[0003] The defects of the existing gas buffer type elevator shock absorbers are as follows: 1. Patent document CN107848752A discloses an elevator system. "The elevator system includes a hoistway having a plurality of landing floors, each landing floor having a landing floor door. One or more guide rails are positioned in the hoistway to guide one or more elevator system components along the hoistway. A shock absorber is positioned at the bottom pit of the hoistway and supports the guide rail among the one or more guide rails. The shock absorber is configured to absorb the load applied to the guide rail due to the vertical translation and / or pressurization of the hoistway. A method of supporting the guide rail of an elevator system includes positioning a shock absorber in the elevator hoistway in a manner operably communicating with the guide rail of the elevator system. The vertically acting load is transmitted from the guide rail to the shock absorber via the shock absorber piston, thereby increasing the fluid pressure in the housing chamber", but the gas pressure of the existing gas buffer type elevator shock absorber cannot be automatically detected, which reduces the shock absorption safety; 2. Patent document CN111924682A discloses a spring shock absorber for an elevator, "including a car body and an elevator shaft. The car body is configured to match in the elevator shaft. A receiving support plate is horizontally arranged in the bottom space of the elevator shaft. An air cushion is arranged on the upper plate surface of the receiving support plate. A main buffer spring is correspondingly configured in the cavity of each support sleeve. A side horizontal buffer spring is also correspondingly sleeved on the column body of each horizontal sliding column. A side vertical buffer spring is also correspondingly sleeved on the rod body of the linkage pull rod. A synchronous downward movement column is vertically fixed at the center position of the upper surface of the downward movement walking block. A trapezoidal chuck is correspondingly clamped between two adjacent trapezoidal teeth among a plurality of trapezoidal teeth. The trapezoidal chuck is adaptively limited in the positioning short cylinder in a movable manner and a reset top spring is also configured in the cavity of the positioning short cylinder. The present invention brings a good buffer and shock absorption effect to personnel and ensures the safety of the entire device", but the No. 9 spring of the existing gas buffer type elevator shock absorber cannot be quickly replaced, increasing the maintenance time of the elevator shock absorber; 3. Patent document CN207844786U discloses an elevator car shock absorber, "including an upper connecting plate and a lower connecting plate arranged opposite to each other. A rubber elastic body is arranged between the upper connecting plate and the lower connecting plate. At least two spring holes are arranged in the rubber elastic body. Through holes matching the spring holes are arranged on the upper connecting plate. Springs are arranged in the spring holes. The outer diameter of the spring fits the inner diameter of the spring hole. Two upper threaded holes are arranged on the upper connecting plate. Lower threaded holes matching the upper threaded holes are arranged on the lower connecting plate. Rounded transitions extending towards the upper connecting plate and the lower connecting plate are respectively arranged at the upper and lower ends of the side wall of the rubber elastic body. The utility model can achieve the dual functions of elevator overload protection weighing and car shock absorption, has excellent performance parameters and high stability, and has the characteristics of wear resistance, high viscosity, good elasticity, non-toxic safety, long service life, etc., and can be widely applied to various passenger and freight elevators", but the shock absorption effect of the existing gas buffer type elevator shock absorber cannot be quickly adjusted, reducing the shock absorption stability; 4. Patent document CN209023975U discloses a spring shock absorber for an elevator, "including a base, a bottom cylinder vertically fixed on the base, and a top cover connected to the bottom cylinder along the length direction of the bottom cylinder. A lifting spring is vertically connected in the cavity. The upper end of the top cover is slidably connected with an anti-slip plate. A plurality of anti-slip springs are horizontally fixed around the edge of the anti-slip plate between the anti-slip plate and the top cover. The utility model solves the technical problem that the elevator will swing during the descending process in the prior art, which will cause the elevator buffer device and the car to bear more impacts and be more easily damaged, and achieves the effect of being able to buffer the swinging elevator in the horizontal direction and is applied to the elevator", but the existing gas buffer type elevator shock absorber cannot be automatically lubricated during movement, reducing the movement stability.

[0025] The usage method of this shock absorber includes the following steps: Step S1. When the processing module detects a high-pressure state, the processing module controls the alarm 8 to start at a low power. After the alarm 8 starts at a low power, the high-frequency pressure sensor 9 continuously detects the real-time pressure data in the air box 6 until the processing module detects a low-pressure state or a proper pressure state. When the processing module detects a low-pressure state, the processing module controls the alarm 8 to start at a high power. After the alarm 8 starts at a high power, the high-frequency pressure sensor 9 continuously detects the real-time pressure data in the air box 6 until the processing module detects a high-pressure state or a proper pressure state. When the processing module detects a proper pressure state, the processing module controls the alarm 8 not to start. After the alarm 8 does not start, the high-frequency pressure sensor 9 continuously detects the real-time pressure data in the air box 6 until the processing module detects a high-pressure state or a low-pressure state, realizing the function of automatically detecting the gas pressure of the gas buffer type elevator shock absorber to improve the shock absorption safety. Step S2: The rotation of the ninth motor 11 drives the rotation of the ninth convex head 13. The rotation of the ninth convex head 13 drives the movement of the eighth buffer pad 20. The movement of the eighth buffer pad 20 drives the movement of the eighth frame 19. The movement of the eighth frame 19 drives the movement of the ninth frame 18. The movement of the ninth frame 18 drives the movement of the third spring 17. The movement of the third spring 17 causes the ninth frame 18 to drive the movement of the ninth chuck 15. The movement of the ninth chuck 15 drives the movement of the ninth buffer pad 16. The movement of the ninth buffer pad 16 causes it to move away from the ninth spring 3. At this time, the ninth spring 3 is taken out for replacement, realizing the function of quickly replacing the ninth spring 3 of the gas buffer type elevator shock absorber and reducing the maintenance time of the elevator shock absorber; Step S3: The function of the fourth frame 25 is to provide support for the fifth cylinder 28. The function of the elastic pad 22 is to provide movement buffer for the ninth pressing plate 4. Pull the eighth rod 27 to drive the movement of the fourth spring 30. The movement of the fourth spring 30 causes the eighth rod 27 to drive the movement of the fifth support rod 29. The movement of the fifth support rod 29 causes the eighth rod 27 to move out of the card slot 23. At this time, move the ninth pressing plate 4 to press the ninth spring 3 to different pressure states, realizing the function of quickly adjusting the shock absorption effect of the gas buffer type elevator shock absorber and improving the shock absorption stability; Step S4: Lubricating oil enters through the oil inlet pipe 44. The oil pump 36 is started to suck the lubricating oil in the storage box 35 into the spring pipe 37. The lubricating oil enters the oil outlet head 42. At this time, the sixth motor 38 rotates to drive the gear 39 to rotate. The rotation of the gear 39 drives the movement of the rack 41. The movement of the rack 41 drives the oil outlet head 42 to move through the seventh opening 43. The movement of the oil outlet head 42 evenly applies the lubricating oil on the surface of the buffer member 32, realizing the function of automatically lubricating during the movement of the gas buffer type elevator shock absorber and improving the movement stability;

[0026] Working principle: When the elevator sinks, it drives the top plate 5 to move. The movement of the top plate 5 drives the buffer member 32 to move. The movement of the buffer member 32 causes the top plate 5 to drive the ninth pressure plate 4 to move. The movement of the ninth pressure plate 4 drives the ninth spring 3 to move. The movement of the ninth spring 3 buffers the impact force when the elevator sinks. When the processing module detects a high-pressure state, the processing module controls the alarm 8 to start with low power. After the alarm 8 starts with low power, the high-frequency pressure sensor 9 continuously detects the real-time pressure data in the air tank 6 until the processing module detects a low-pressure state or a proper-pressure state. When the processing module detects a low-pressure state, the processing module controls the alarm 8 to start with high power. After the alarm 8 starts with high power, the high-frequency pressure sensor 9 continuously detects the real-time pressure data in the air tank 6 until the processing module detects a high-pressure state or a proper-pressure state. When the processing module detects a proper-pressure state, the processing module controls the alarm 8 not to start. After the alarm 8 does not start, the high-frequency pressure sensor 9 continuously detects the real-time pressure data in the air tank 6 until the processing module detects a high-pressure state or a low-pressure state. This realizes the function of automatically detecting the gas pressure of the gas buffer type elevator shock absorber to improve shock absorption safety. The ninth motor 11 rotates to drive the ninth convex head 13 to rotate. The rotation of the ninth convex head 13 drives the eighth buffer pad 20 to move. The movement of the eighth buffer pad 20 drives the eighth frame 19 to move. The movement of the eighth frame 19 drives the ninth frame 18 to move. The movement of the ninth frame 18 drives the third spring 17 to move. The movement of the third spring 17 causes the ninth frame 18 to drive the ninth chuck 15 to move. The movement of the ninth chuck 15 drives the ninth buffer pad 16 to move. The movement of the ninth buffer pad 16 causes it to move away from the ninth spring 3. At this time, the ninth spring 3 can be taken out for replacement. This realizes the function of quickly replacing the ninth spring 3 of the gas buffer type elevator shock absorber to reduce the maintenance time of the elevator shock absorber. The function of the fourth frame 25 is to provide support for the fifth cylinder 28. The function of the elastic pad 22 is to provide movement buffer for the ninth pressure plate 4. Pull the eighth lever 27 to drive the fourth spring 30 to move. The movement of the fourth spring 30 causes the eighth lever 27 to drive the fifth support rod 29 to move. The movement of the fifth support rod 29 causes the eighth lever 27 to move out of the card slot 23. At this time, move the ninth pressure plate 4 to press the ninth spring 3 to different pressure states. This realizes the function of quickly adjusting the shock absorption effect of the gas buffer type elevator shock absorber to improve shock absorption stability. Lubricating oil enters through the oil inlet pipe 44. The oil pump 36 starts to suck the lubricating oil in the storage box 35 into the spring pipe 37. The lubricating oil enters the oil outlet head 42. At this time, the sixth motor 38 rotates to drive the gear 39 to rotate. The rotation of the gear 39 drives the rack 41 to move. The movement of the rack 41 drives the oil outlet head 42 to move through the seventh opening 43. The movement of the oil outlet head 42 evenly applies the lubricating oil on the surface of the buffer member 32. This realizes the function of automatically lubricating during the movement of the gas buffer type elevator shock absorber to improve movement stability.
