For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0021] The present application will be further elaborated in detail below with reference to the drawings and embodiments.

[0022] Referring to Figures 1 to 9 , an elevator with an emergency locking mechanism is provided in an embodiment of the present application, including a car 1. A protection component 3 is arranged at the top of the car 1. A locking component 2 is arranged outside the protection component 3. A buffer component 4 is arranged at the bottom of the car 1. The protection component 3 includes a top plate 31. An external block 33 is fixedly installed at the bottom of the top plate 31. An insertion block 34 is fixedly installed at the top of the car 1. The insertion block 34 is inserted into the external block 33. A first shock absorber 32 is fixedly installed between the top plate 31 and the car 1. The locking component 2 includes a guiding rack 21 and a connecting block 23. The connecting block 23 is fixedly installed on the left and right sides of the top plate 31. A wheel frame 24 is fixedly installed outside the connecting block 23. A rotating shaft 26 is rotatably connected between the wheel frames 24. A locking gear 22 is fixedly installed on the outside of the rotating shaft 26. The locking gear 22 meshes with the guiding rack 21 on the corresponding side. The guiding rack 21 is fixedly installed on the left and right inner walls of the elevator shaft.

[0023] An external cover 25 is fixedly installed on the front surface of the wheel frame 24. An auxiliary block 27 is fixedly installed on the front surface of the rotating shaft 26. The auxiliary block 27 is rotatably connected inside the external cover 25. A first sliding groove 28 is formed inside the auxiliary block 27. A clamping plate 29 is slidably connected inside the first sliding groove 28. A first spring 210 is fixedly installed between the clamping plate 29 and the inner wall of the first sliding groove 28. A clamping tooth 213 is fixedly installed on the inner wall of the external cover 25. A groove 211 is formed inside the auxiliary block 27. An arc-shaped elastic piece 212 is fixedly installed inside the groove 211. The arc-shaped edge of the arc-shaped elastic piece 212 is inserted into the clamping plate 29.

[0024] In this embodiment, during the normal operation of the elevator, the car 1 relies on the drive system to smoothly lift and lower along the guide rack 21 in the elevator shaft. The locking gear 22 in the locking assembly 2 meshes with the guide rack 21 to play a guiding role and ensure the stable running direction of the car 1. At this time, the rotating shaft 26 drives the locking gear 22 to rotate smoothly between the wheel frames 24, and the auxiliary block 27 rotates synchronously inside the outer cover 25. Under the action of the first spring 210, the clamping plate 29 is in a non-clamping state with the tooth 213 and will not hinder the rotation of the rotating shaft 26, ensuring the normal lifting and lowering of the car 1. The top plate 31 in the protection assembly 3 is connected to the top of the car 1 through the first shock absorber 32. The first shock absorber 32 can absorb the vibration generated during the operation of the car 1 and make the operation of the car 1 more stable. The insertion block 34 is inserted into the external block 33. Under normal circumstances, under the action of the second spring 37, the arc-shaped edge of the locking block 38 is inserted into the insertion block 34 to realize the firm connection between the top plate 31 and the car 1. The buffer plate 41 in the buffer assembly 4 is in a relatively static state at the bottom inside the car 1. The second shock absorber 47 does not undergo compression deformation during normal operation. The piston plate 48 and the connecting rod 49 in the air box 43 also remain stationary, and there is no pressure change in the gas inside the pressure box 46. When an emergency such as an abnormal rapid descent of the elevator occurs, the locking assembly 2 starts to perform the emergency locking function. The rapid descent of the car 1 drives the locking gear 22 to rotate at an accelerated speed, and the rotating shaft 26 rotates at a high speed accordingly. During the rapid rotation of the auxiliary block 27, the clamping plate 29 inside overcomes the elastic force of the first spring 210 due to the centrifugal force and slides outward in the first chute 28 until the clamping plate 29 engages with the tooth 213 on the inner wall of the outer cover 25, thereby restricting the rotation of the rotating shaft 26 and stopping the rotation of the locking gear 22. Since the locking gear 22 meshes with the guide rack 21, the stop rotation of the locking gear 22 can quickly fix the car 1 in the elevator shaft to achieve emergency braking and prevent the car 1 from continuing to fall and causing danger. At the same time, the impact force generated by the rapid descent of the car 1 is transmitted to the extrusion block 36 inside the external block 33 through the insertion block 34. The extrusion block 36 overcomes the elastic force of the second spring 37 and extrudes the locking block 38, causing the locking block 38 to withdraw from the insertion block 34, temporarily releasing the connection between the top plate 31 and the car 1. The first shock absorber 32 is further compressed to play a buffering role and reduce the impact force received by the car 1.

[0025] Refer to Figures 1 to 9, in one aspect of the present embodiment, a second sliding groove 35 is provided inside the outer block 33. An extrusion block 36 and a clamping block 38 are slidably connected inside the second sliding groove 35. A second spring 37 is fixedly installed between the extrusion block 36 and the clamping block 38. The outer side of the clamping block 38 is arc-shaped, and the arc-shaped side of the clamping block 38 is inserted inside the insertion block 34. A limiting block 39 is fixedly installed on the outer side of the outer block 33, and the limiting block 39 is attached to the outer side of the corresponding extrusion block 36. The buffer assembly 4 includes a buffer plate 41. The buffer plate 41 is slidably connected to the inner bottom of the car 1. A bottom shell 42 is fixedly installed at the bottom of the car 1. A second shock absorber 47 is fixedly installed inside the bottom shell 42, and the top of the second shock absorber 47 is fixedly installed at the bottom of the buffer plate 41. A gas box 43 is fixedly installed at the bottom of the car 1. A piston plate 48 is slidably connected inside the gas box 43. A connecting rod 49 is fixedly installed at the top of the piston plate 48. The connecting rod 49 movably penetrates the bottom wall of the car 1 and is fixedly connected to the bottom of the buffer plate 41. A connecting pipe 44 is fixedly installed at the bottom of the gas box 43. The connecting pipe 44 is in communication with the inside of the gas box 43. Pressure boxes 46 are fixedly installed on both the left and right sides of the outer block 33. The pressure boxes 46 are located on the outer side of the extrusion block 36. A split pipe 45 is fixedly installed on the outer side of the pressure box 46. The outer ends of the two split pipes 45 are fixedly connected to the top of the connecting pipe 44. The connecting pipe 44 is in communication with the inside of the split pipe 45, and the split pipe 45 is in communication with the inside of the pressure box 46.

[0026] In this embodiment, as the number of passengers or goods in the car 1 increases, the pressure on the buffer plate 41 increases, and the downward movement distance also increases accordingly. This causes the piston plate 48 to compress the gas in the gas tank 43 more intensively, and more gas enters the pressure tank 46 through the connecting pipe 44 and the split pipe 45, resulting in an increase in the internal pressure of the pressure tank 46; conversely, when the number of passengers in the car 1 decreases, the downward movement distance of the buffer plate 41 becomes smaller, the internal pressure of the pressure tank 46 decreases, and the pressure tank 46 is located outside the outer block 33 and outside the extrusion block 36. The change in the internal pressure of the pressure tank 46 will generate different degrees of thrust on the extrusion block 36. The greater the pressure, the greater the thrust on the extrusion block 36; the smaller the pressure, the smaller the thrust. A second spring 37 is installed between the extrusion block 36 and the latch 38, and a limiting block 39 is fixedly installed on the outside of the outer block 33 and fits on the outside of the extrusion block 36. The thrust generated by the change in the internal pressure of the pressure tank 46 acts on the extrusion block 36. When the pressure increases, the extrusion block 36 moves towards the latch 38 against the elastic force of the second spring 37, further compressing the second spring 37; when the pressure decreases, the second spring 37 pushes the extrusion block 36 to reset. Since the outside of the latch 38 is arc-shaped, its arc edge is inserted into the inside of the insert block 34. The change in the compression degree of the second spring 37 directly affects the fixing strength between the latch 38 and the insert block 34. The greater the compression degree of the second spring 37, the more firmly the latch 38 and the insert block 34 are fixed, and a greater inertial force is required to withdraw the latch 38 from the insert block 34 to achieve the release of the connection between the outer block 33 and the insert block 34; conversely, the smaller the compression degree of the second spring 37, the lower the fixing strength, and a smaller inertial force can release the connection between the two. In this way, by changing the internal pressure of the pressure tank 46 according to the number of people carried in the car 1, the compression degree of the second spring 37 is adjusted, and finally, according to the different inertias caused by different numbers of passengers, the inertial force required to automatically release the fixation between the outer block 33 and the insert block 34 is adjusted, ensuring that in case of an emergency, whether the elevator is empty or full, the emergency response mechanism of the protection component 3 can be reasonably triggered, improving the safety and reliability of the elevator operation.

[0027] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0028] Working principle: During normal operation of the elevator, the car 1 is lifted and lowered smoothly along the guide rack 21 by the driving system in the elevator shaft. The locking gear 22 in the locking assembly 2 is meshed with the guide rack 21 to play a guiding role, ensuring that the running direction of the car 1 is stable. At this time, the rotating shaft 26 drives the locking gear 22 to rotate smoothly between the wheel frame 24, and the auxiliary block 27 rotates synchronously in the external cover 25. The card plate 29 is in a non-engaged state with the card tooth 213 under the action of the first spring 210, and will not hinder the rotation of the rotating shaft 26, ensuring the normal lifting and lowering of the car 1. The top plate 31 in the protective assembly 3 is connected to the top of the car 1 through the first shock absorber 32. The first shock absorber 32 can absorb the vibration generated during the operation of the car 1, so that the car 1 can run smoothly. More stable, the plug block 34 is inserted into the inside of the external block 33. Under normal circumstances, the arcuate edge of the card block 38 is inserted into the inside of the plug block 34 under the action of the second spring 37, so as to realize the stable connection between the top plate 31 and the car 1. The buffer plate 41 in the buffer assembly 4 is in a relatively static state at the bottom of the car 1. The second shock absorber 47 does not undergo compression deformation during normal operation. The piston plate 48 and the connecting rod 49 in the air box 43 also remain stationary. There is no pressure change in the gas inside the pressure box 46. When the elevator encounters an emergency such as an abnormal rapid descent, the locking assembly 2 starts to play the emergency locking function. The rapid descent of the car 1 drives the locking gear 22 to accelerate the rotation, and the shaft 26 rotates at high speed accordingly. During the rapid rotation of the auxiliary block 27, the internal card plate 29 Due to the centrifugal force, the elastic force of the first spring 210 is overcome and the car slides outward in the first slide groove 28 until the card plate 29 engages with the card teeth 213 on the inner wall of the outer cover 25, thereby limiting the rotation of the rotating shaft 26 and stopping the rotation of the locking gear 22. Since the locking gear 22 is engaged with the guide rack 21, the stopping of the locking gear 22 can quickly fix the car 1 in the elevator shaft, realizing emergency braking and preventing the car 1 from continuing to fall and causing danger. At the same time, the impact force generated by the rapid descent of the car 1 is transmitted to the squeezing block 36 in the outer block 33 through the insert block 34. The squeezing block 36 overcomes the elastic force of the second spring 37 and squeezes the card block 38, so that the card block 38 withdraws from the insert block 34. The connection between the top plate 31 and the car 1 is temporarily released, and the first vibration reduction The device 32 is further compressed to play a buffering role, reducing the impact force on the car 1. As the number of passengers or cargo in the car 1 increases, the pressure on the buffer plate 41 increases, and the distance it moves downward also increases accordingly, which makes the piston plate 48 compress the gas in the air box 43 more. More gas enters the pressure box 46 through the connecting pipe 44 and the branch pipe 45, causing the pressure inside the pressure box 46 to increase; conversely, when the number of people in the car 1 decreases, the distance the buffer plate 41 moves downward becomes smaller, and the pressure inside the pressure box 46 decreases. The pressure box 46 is located on the outside of the extrusion block 36 outside the outer block 33. The change in the internal pressure of the pressure box 46 will produce different degrees of thrust on the extrusion block 36. The greater the pressure, the greater the thrust on the extrusion block 36.The smaller the pressure, the smaller the thrust. A second spring 37 is installed between the extrusion block 36 and the clamping block 38, and a limit block 39 is fixedly installed on the outside of the external block 33 to fit the outside of the extrusion block 36. The thrust generated by the pressure change inside the pressure box 46 acts on the extrusion block 36. When the pressure increases, the extrusion block 36 overcomes the elastic force of the second spring 37 and moves toward the clamping block 38, further compressing the second spring 37; when the pressure decreases, the second spring 37 pushes the extrusion block 36 to reset. Since the outer side of the clamping block 38 is arc-shaped, its arcuate edge is inserted into the inside of the plug-in block 34. The change in the extrusion degree of the second spring 37 directly affects the fixing strength between the clamping block 38 and the plug-in block 34. The greater the compression degree of the second spring 37, the closer the clamping block 38 and the plug-in block The stronger the fixation between the outer block 33 and the insert 34, the greater the inertial force required to withdraw the locking block 38 from the insert 34, thereby releasing the connection between the outer block 33 and the insert 34. Conversely, the less compressed the second spring 37, the lower the fixing strength, and the smaller the inertial force required to release the connection between the two. In this way, the internal pressure of the pressure box 46 is changed by the number of people loaded in the car 1, and the degree of compression of the second spring 37 is adjusted. Ultimately, the inertial force required to release the fixation between the outer block 33 and the insert 34 is automatically adjusted according to the different inertias caused by different number of people carried. This ensures that in an emergency, whether the elevator is empty or fully loaded, the emergency response mechanism of the protection assembly 3 can be properly triggered, thereby improving the safety and reliability of elevator operation.
