Description

Technical Field

[0001] This invention relates to the field of elevator technology, and in particular to a vertical elevator with multiple emergency protection structures. Background Technology

[0002] Elevators are a common tool, but they are prone to various malfunctions during prolonged use. If the elevator's braking system malfunctions, it can cause the elevator to plummet. Existing safety devices, such as brake clamps, will immediately clamp the guide rails on the inner wall of the elevator shaft during a rapid descent, thus achieving an emergency braking effect to protect the safety of people inside the elevator. After the elevator stops, firefighters can then open the elevator doors to rescue those trapped inside.

[0003] Because the brake caliper generates intense friction during braking, it is subjected to enormous compressive force and generates a great deal of heat. After the elevator stops, it is difficult to guarantee that the brake caliper will not be damaged. During fire rescue, if the trapped person is injured, firefighters need to enter the elevator to carry the trapped person out. This process will cause changes in the weight inside the elevator. If the brake caliper is damaged at this time, the elevator will fall again, especially when passing through the elevator door, which can easily cause injury to people.

[0004] Without professional assistance, if trapped individuals accidentally open the elevator door, it is impossible to determine whether the elevator is locked or whether it will slip. If trapped individuals exit the elevator at this time, and the elevator slips, it will pose a significant threat to them. Summary of the Invention

[0017] This invention detects whether the elevator car is slipping by measuring the speed of the traction rope.

Detailed Implementation

[0032] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] When an elevator malfunctions and falls, the brakes on the elevator slow the descent through friction and bring the elevator to a stop. During braking, the brakes generate intense friction and immense pressure, producing significant heat. After the elevator stops, if trapped individuals are injured during rescue operations, firefighters need to enter the elevator to carry them out. This process causes changes in weight within the elevator. If the brakes fail, the elevator may fall again, especially when passing through the elevator doors, potentially causing injury. Therefore, this invention improves upon this by implementing the following steps:

[0034] Example 1: A vertical elevator with multiple emergency protection structures, referring to... Figures 1-5 As shown, the system includes a fixed frame 1, to which two symmetrically distributed guide rails 11 are fixedly connected. A car 12 is slidably connected between the two symmetrically distributed guide rails 11. Two symmetrically distributed sliding doors 13 are slidably connected to the front of the car 12. Equally spaced traction ropes 14 are fixedly connected to the upper side of the car 12. A traction machine 15 is fixedly connected to the upper side of the fixed frame 1. A counterweight block 16 is fixedly connected to the end of the traction rope 14 away from the car 12, passing over the fixed frame 1 and the traction machine 15. Brake calipers 17 are fixedly connected to both the left and right sides of the car 12. The brake calipers 17 are symmetrically distributed, and two symmetrically distributed brake blocks 18 are slidably connected inside the brake calipers 17. Two symmetrically distributed mounting brackets 2 are fixedly connected to both the left and right sides of the car 12. The mounting brackets 2 are located on the upper side of the car 12 and are slidably connected to the adjacent guide rails 11. The first limiting block 21 and the second limiting block 22 are in a compression fit. In use, the first limiting block 21 and the second limiting block 22 compress the adjacent guide rail 11 to prevent the car 12 from moving. The first limiting block 21 is located above the adjacent second limiting block 22. The side of the first limiting block 21 closest to the adjacent mounting frame 2 is inclined. The first limiting block 21 is inclined from bottom to top away from the adjacent mounting frame 2. The inclination directions of the first limiting block 21 and the adjacent second limiting block 22 are opposite. The first limiting block 21 and the second limiting block 22 are both in a compression fit with the adjacent mounting frame 2. In use, the first limiting block 21 compresses the adjacent mounting frame 2 upward, and the second limiting block 22 compresses the adjacent mounting frame 2 downward. The car 12 is provided with a power component for driving the first limiting block 21 and the second limiting block 22 to move.

[0035] Reference Figure 3 and Figures 5-7As shown, the power assembly includes two symmetrically distributed fixed columns 3, which are rotatably connected to the upper side of adjacent sliding doors 13. A telescopic rod 31 is fixedly connected to each fixed column 3, and a rotating ring is fixedly connected to the end of the telescopic rod 31 away from the adjacent fixed column 3. Two symmetrically distributed first fixed pipes 311 are fixedly connected to the upper side of the car 12. The telescopic rod 31 is rotatably connected to the adjacent first fixed pipe 311 via the rotating ring. A rotating ring 32 is rotatably connected to the telescopic rod 31 via the rotating ring. The rotating ring 32 is located above the telescopic rod 31 and is fixedly connected to a first fixed block 33. The rear side of 3 is a square rod. The first fixing block 33 is slidably connected to the limiting frame 34. The limiting frame 34 has a groove. The first fixing block 33 slides in the groove of the adjacent limiting frame 34. The limiting frame 34 is slidably connected to two transmission frames 35 symmetrically distributed front and rear. The first limiting block 21 and the adjacent second limiting block 22 are slidably connected to the adjacent transmission frame 35. The first limiting block 21 and the adjacent second limiting block 22 slide on the adjacent transmission frame 35. A fixing component is provided on the outside of the car 12. The fixing component is used to fix the telescopic rod 31 and the adjacent rotating ring 32.

[0036] Reference Figure 4 , Figure 6 and Figure 7 As shown, the fixing assembly includes two second fixing tubes 4 symmetrically distributed on the left and right sides. The two second fixing tubes 4 are respectively fixed to the left and right sides of the car 12. The lower end of the second fixing tube 4 is slidably connected to a first piston rod 41. One end of the piston of the first piston rod 41 faces upward and is located inside the adjacent second fixing tube 4. The first piston rod 41 is in contact with the adjacent brake block 18. When the brake block 18 brakes, the brake block 18 moves upward relative to the car 12, thereby pressing the adjacent first piston rod 41, causing the first piston rod 41 to move upward relative to the car 12. The second fixed tube 4 is filled with hydraulic oil and is connected to the adjacent first fixed tube 311. The upper side of the first fixed tube 311 rotates and is connected to the third fixed tube 42. The third fixed tube 42 is located inside the rotating ring on the adjacent telescopic rod 31 and inside the adjacent rotating ring 32. The third fixed tube 42 slides and is connected to the circumferentially arrayed limiting posts 43. The rotating ring on the telescopic rod 31 and the rotating ring 32 are both provided with grooves that are limited and matched with the adjacent limiting posts 43. Initially, the limiting posts 43 do not contact the rotating ring on the adjacent telescopic rod 31 or the adjacent rotating ring 32.

[0037] Reference Figure 6 and Figure 8As shown, a second piston rod 5 is slidably connected to a second fixed tube 4. The end of the second piston rod 5 away from its own piston passes through an adjacent second fixed tube 4. A sealing ring 51 is slidably connected to an adjacent second fixed tube 4. The part of the second piston rod 5 passing through the second fixed tube 4 is not sealed. A sealing ring 51 is slidably connected to the second piston rod 5. There is hydraulic oil between the sealing ring 51 and the piston on the adjacent second piston rod 5. There is no hydraulic oil on the upper side of the sealing ring 51. A first spring 52 is fixedly connected between the sealing ring 51 and the adjacent second fixed tube 4. The first spring 52 is used to reset the adjacent sealing ring 51. A fixed ring 53 is fixedly connected to the upper side of the second fixed tube 4. A groove is opened in the fixed ring 53. The second piston rod 5 slides in the groove of the adjacent fixed ring 53. The upper side of the second piston rod 5 is rotatably connected to the first limiting ring 54. The first limiting ring 54 is in limiting engagement with the adjacent fixed ring 53. The first limiting ring 54 slides in the groove of the adjacent fixed ring 53. The upper side of the fixed ring 53 is fixedly connected to a square block that is in limiting engagement with the adjacent first limiting ring 54. When the first limiting ring 54 is disengaged from the groove of the adjacent fixed ring 53, the square block on the upper side of the fixed ring 53 limits the adjacent first limiting ring 54. A torsion spring 55 is fixedly connected between the first limiting ring 54 and the adjacent second piston rod 5. The torsion spring 55 is used to drive the adjacent first limiting ring 54 to rotate. Initially, the torsion spring 55 stores force.

[0038] Reference Figure 5 and Figure 9As shown, a reset frame 6 is slidably connected to the mounting bracket 2. A reset block 61 is slidably connected to the upper side of the reset frame 6. A second spring 62 is fixed between the reset block 61 and the adjacent mounting bracket 2. The second spring 62 is used to support the reset block 61. The reset frame 6 is provided with threads and a nut. The nut and the adjacent reset block 61 are pressed together. The reset frame 6 is pressed together with the adjacent second limiting block 22. The reset block 61 is pressed together with the adjacent first limiting block 21. When the reset frame 6 and the adjacent reset block 61 approach each other, the reset block 61 presses against the adjacent first limiting block 21, and the reset frame 6 presses against the adjacent second limiting block 22. The reset frame 6 and the adjacent reset block 61 are used to reset the first limiting block 21 and the adjacent second limiting block 22. A third limiting block 63 is fixedly connected to the second limiting block 22. The third limiting block 63 is slidably connected with a spring that limits the adjacent first limiting block 21. Initially, the elastic block 631 limits the adjacent first limiting block 21, causing the first limiting block 21 and the adjacent second limiting block 22 to move closer to each other. The first limiting block 21 is slidably connected to a fourth limiting block 64, which is in a pressing fit with the adjacent elastic block 631 and the adjacent mounting bracket 2. When the second limiting block 22 moves towards the car 12, the fourth limiting block 64 moves towards the adjacent elastic block 631 under the pressure of the adjacent mounting bracket 2. The elastic block 631 is compressed and retracts into the adjacent limiting block 63, unlocking the first limiting block 21. An elastic element 65, which is a spring, is fixed between the first limiting block 21 and the adjacent second limiting block 22. Initially, the elastic element 65 stores force and is used to separate the adjacent first limiting block 21 and the adjacent second limiting block 22.

[0039] During the use of this device, if the elevator is working normally, when the sliding door 13 is opened, taking the right sliding door 13 as an example, the right sliding door 13 moves to the right and drives the fixed column 3 to move to the right. The fixed column 3 drives the front end of the telescopic rod 31 to move to the right, so that the telescopic rod 31 rotates counterclockwise (from top to bottom) around the first fixed tube 311. The telescopic rod 31 retracts. At this time, the limiting column 43 on the third fixed tube 42 does not contact the ring and rotating ring 32 on the telescopic rod 31, and the telescopic rod 31 cannot drive the rotating ring 32.

[0040] During normal operation of the elevator, the traction machine 15 drives the traction rope 14 to move, the traction rope 14 drives the car 12 to move up and down, and the counterweight 16 moves up and down in the opposite direction to the car 12.

[0041] If the elevator traction machine 15 malfunctions, after the user enters the car 12 (at this time, the total weight of the car 12 and the personnel inside it is greater than the weight of the counterweight 16), the traction machine 15 cannot move the car 12 through the traction rope 14. The car 12 stalls and falls under the action of gravity. When the car 12 stalls and falls, taking the right brake caliper 17 as an example, when the car 12 stalls and falls, the two brake blocks 18 in the brake caliper 17 move upward relative to the car 12 and squeeze the adjacent guide rail 11. The friction between the two brake blocks 18 and the guide rail 11 slows down the descent speed of the car 12, thereby stopping the car 12. When the brake blocks 18 rise, one of the brake blocks 18 drives the adjacent first piston rod 41 to move upward.

[0042] During the upward movement of the first piston rod 41, the first piston rod 41 presses upward against the hydraulic oil in the second fixed tube 4. The hydraulic oil presses against the second piston rod 5, causing the second piston rod 5 to move upward. The second piston rod 5 drives the first limiting ring 54 to slide within the fixed ring 53. When the first limiting ring 54 disengages from the fixed ring 53, the torsion spring 55 drives the first limiting ring 54 to rotate until the first limiting ring 54 contacts the square block on the fixed ring 53, and then stops, fixing the second piston rod 5 and preventing it from descending.

[0043] During the upward movement of the second piston rod 5, the hydraulic oil on the upper side of the second piston rod 5 moves upward along the second fixed pipe 4 until the hydraulic oil enters the first fixed pipe 311. The hydraulic oil in the first fixed pipe 311 enters the third fixed pipe 42 and squeezes the limiting post 43 on the third fixed pipe 42. The limiting post 43 gradually contacts the adjacent rotating ring 32 or the adjacent telescopic rod 31 and enters the groove of the rotating ring 32 or the adjacent telescopic rod 31. Since it is impossible to determine whether the limiting post 43 corresponds to the groove on the adjacent rotating ring 32 or the groove on the adjacent telescopic rod 31 during use, when the limiting post 43 cannot enter the corresponding groove, the limiting post 43 no longer enters the hydraulic oil. At this time, the excess hydraulic oil squeezes the sealing ring 51, and the sealing ring 51 moves upward to squeeze the first spring 52. Under the compression of the first spring 52, the limiting post 43 always maintains an outward force through the transmission of hydraulic oil.

[0044] If rescuers open sliding door 13 at this time, during the opening process of sliding door 13, taking the right sliding door 13 as an example, as sliding door 13 drives telescopic rod 31 to rotate via fixed post 3, the groove in the rotating ring of telescopic rod 31 gradually aligns with the adjacent limiting post 43. The first spring 52 is released, causing the adjacent sealing ring 51 to move downwards and compress the hydraulic oil. The hydraulic oil compresses the limiting post 43, causing the limiting post 43 to move outwards into the adjacent groove. Then, telescopic rod 31 drives the third fixed tube 42 to rotate via the limiting post 43. The fixed tube 42 drives the upper limiting post 43 to rotate. The limiting post 43 on the third fixed tube 42, corresponding to the rotating ring 32, gradually enters the groove of the rotating ring 32. At this time, the telescopic rod 31 drives the rotating ring 32 to rotate counterclockwise through the third fixed tube 42 and the limiting post 43. The rotating ring 32 drives the first fixed block 33 to rotate. The first fixed block 33 drives the limiting frame 34 to move to the left. The limiting frame 34 drives the two transmission frames 35 to move to the left. The transmission frames 35 drive the adjacent first limiting block 21 and the adjacent second limiting block 22 to move to the left.

[0045] During the leftward movement of the first limiting block 21 and the second limiting block 22, taking the first limiting block 21 and the second limiting block 22 corresponding to a transmission frame 35 as an example, initially, the first limiting block 21 and the second limiting block 22 form a whole under the action of the third limiting block 63 and the elastic block 631. During the leftward movement of the first limiting block 21 and the second limiting block 22, the fourth limiting block 64 gradually contacts the left side of the mounting frame 2. The mounting frame 2 contacts and presses the fourth limiting block 64, causing the fourth limiting block 64 to move to the right relative to the first limiting block 21, and gradually presses the elastic block 631, causing the elastic block... 631 gradually enters the third limiting block 63. After the elastic block 631 is fully inside the third limiting block 63, the elastic element 65 is released, separating the first limiting block 21 and the second limiting block 22. This causes the first limiting block 21 to move upward and contact the mounting frame 2. Under the pressure of the inclined surface on the mounting frame 2, the first limiting block 21 moves closer to the guide rail 11 and contacts the guide rail 11. At this time, the transmission frame 35 slides within the adjacent limiting frame 34. The first limiting block 21 and the second limiting block 22 slide relative to the adjacent transmission frame 35. The first limiting block 21 and the second limiting block 22 press against the guide rail 11 to fix the car 12.

[0046] When the brake block 18 inside the brake caliper 17 is activated, during the door opening process, the car 12 is fixed again by the first limit block 21 and the second limit block 22 to prevent the brake caliper 17 from being damaged during braking, which could cause the car 12 to slip again due to weight changes inside the car during rescue, endangering the personal safety of the users.

[0047] After all the trapped people were rescued, the maintenance personnel repaired the traction machine 15 and the brake caliper 17. After the repair was completed, the first limit block 21 was reset. By rotating the nut on the reset frame 6, the reset frame 6 moved the adjacent reset blocks 61 closer to each other. The reset frame 6 and the reset blocks 61 gradually squeezed the adjacent first limit block 21 and the adjacent second limit block 22, so that the first limit block 21 and the adjacent second limit block 22 contacted each other and reset. At the same time, the second spring 62 was compressed. Then the maintenance personnel reset the first limit ring 54. After the first limit ring 54 was reset, the rotating ring 32 no longer followed the telescopic rod 31 to rotate. Then the parts in the mounting frame 2 were reset, the first piston rod 41 was reset, and the limit post 43 disengaged from the groove on the ring of the adjacent telescopic rod 31 or the groove of the adjacent rotating ring 32.

[0048] Example 2: Based on Example 1, referring to... Figure 1 , Figure 10 , Figure 11 and Figure 13 As shown, it also includes two symmetrically distributed first rotating shafts 7, both of which are fixed to the upper side of the fixed frame 1. Two symmetrically distributed second rotating shafts 71 are fixed to the lower side of the fixed frame 1. A traction rope 72 passing through the fixed frame 1 is wound between the first rotating shaft 7 and the adjacent second rotating shaft 71. The traction rope 72 passes through the second fixed block 74 and the third fixed block 75. The traction rope 72 is fixed to the counterweight block 16. A fixed seat 73 is fixed to the lower side of the fixed frame 1. The second fixed block 74 is slidably connected inside the fixed seat 73. The third fixed block 75 is slidably connected to the middle of the second fixed block 74. Two symmetrically distributed fixing mechanisms are provided on the upper side of the second fixed block 74. The fixing mechanisms are used to fix the adjacent traction ropes 72. Two symmetrically distributed triggering components are provided on the upper side of the second fixed block 74. The triggering components are used to trigger the adjacent fixing mechanisms.

[0049] Reference Figure 11 and Figure 12As shown, the triggering component includes two symmetrically distributed fixed shafts 8, both fixedly connected to the upper side of the third fixed block 75. Two symmetrically distributed rotating frames 81 are rotatably connected to the fixed shafts 8, and a rotating shaft 82 is rotatably connected between the two symmetrically distributed rotating frames 81. The rotating shaft 82 contacts the adjacent traction rope 72, and a groove is provided in the middle of the rotating shaft 82 to mate with the adjacent traction rope 72. Three circumferentially distributed fifth limiting blocks 83 are slidably connected to both the front and rear sides of the rotating shaft 82, and the three circumferentially distributed fifth limiting blocks 83 are spaced far apart from each other. Each end is fixed with a triangular block. A first tension spring 84 is fixed between the fifth limiting block 83 and the adjacent rotating shaft 82. The first tension spring 84 is used to reset the adjacent fifth limiting block 83. The rotating frame 81 is rotatably connected to a second limiting ring 85. The inner ring of the second limiting ring 85 is provided with three triangular blocks that limit and cooperate with the adjacent fifth limiting block 83. The second limiting ring 85 limits and cooperates with the adjacent rotating frame 81. Two square blocks are provided inside the rotating frame 81. The inner ring of the limiting ring 85 is provided with a square block between the two square blocks on the adjacent rotating frame 81, thereby limiting the limiting ring 85. The rotation angle is adjusted. An elastic pull rope 86 is fixedly connected between the second limiting ring 85 and the adjacent rotating frame 81. A limiting pin 87 is slidably connected to the rotating frame 81. A second tension spring 88 is fixedly connected between the limiting pin 87 and the adjacent rotating frame 81. The second tension spring 88 is used to reset the adjacent limiting pin 87. A tension rope 89 is fixedly connected to the limiting pin 87. One end of the tension rope 89 away from the adjacent limiting pin 87 is fixedly connected to the adjacent second limiting ring 85. The tension rope 89 passes through the adjacent rotating frame 81. The limiting pin 87 is in a limiting engagement with the adjacent fixed shaft 8. The fixed shaft 8 has two holes. Initially, the limiting pin... 87 is located in adjacent holes on adjacent fixed shafts 8. The adjacent fixed shafts 8 and adjacent rotating frames 81 are fixed by limiting pins 87. A fixed plate 810 is fixed between two symmetrically distributed rotating frames 81. The fixed plate 810 is located on the lower side of the adjacent rotating frames 81. Two sets of square blocks are fixed on the upper side of the third fixed block 75. Each set of square blocks consists of two symmetrically distributed blocks. The third fixed block 75 is slidably connected to the third limiting rod 811 through the square blocks. The third limiting rod 811 is pressed and engaged with the adjacent fixed plate 810. When the fixed plate 810 moves, it presses the adjacent third limiting rod 811 to move.

[0050] Reference Figures 11-12As shown, the fixing mechanism includes a fourth spring 9, which is fixed between the upper square block of the third fixing block 75 and the adjacent third limiting rod 811. The fourth spring 9 is used to make the adjacent third limiting rod 811 contact the adjacent fixing plate 810. The end of the third limiting rod 811 away from the adjacent fixing plate 810 is slidably connected to a sixth limiting block 91. The sixth limiting block 91 is composed of two semi-circular frustum blocks spliced ​​together, and the diameter gradually decreases from the middle to the top and bottom sides. The sixth limiting block 91 has a semi-cylindrical groove. The third fixing block 75 is fixedly connected to a third limiting ring 92. The lower side of the third limiting ring 92 is provided with an inclined surface. The two symmetrically distributed sixth limiting blocks 91 cooperate with the third limiting ring 92 for limiting. The sixth limiting block 91 is in frictional cooperation with the adjacent traction rope 72. When the sixth limiting block 91 contacts the adjacent traction rope 72, the traction rope 72 drives the adjacent sixth limiting block 91 to move upward and contact the adjacent third limiting ring 92.

[0051] Reference Figure 13 As shown, the third fixed block 75 is fixedly connected to two symmetrically distributed first damping rods 93. The telescopic ends of the first damping rods 93 are fixedly connected to the second fixed block 74. The second fixed block 74 and the fixed seat 73 are fixedly connected to the second damping rod 94, which is used to slow down the rising speed of the counterweight.

[0052] When the elevator experiences a sudden drop, the counterweight 16 rises, causing the traction rope 72 to rotate rapidly. This causes the traction rope 72 between the two rotating shafts 82 to rise rapidly. The traction rope 72 drives the rotating shaft 82 to rotate rapidly. Taking the right-side traction rope 72 as an example, the rotating shaft 82 drives the fifth limiting block 83 inside it to rotate rapidly. The centrifugal force generated by the rotation of the fifth limiting block 83 overcomes the tension of the first tension spring 84 and spreads outward. The fifth limiting block 83 gradually contacts the adjacent second limiting ring 85, which then limits the movement of the fifth limiting block 83. When the counterweight 16 rises normally, the fifth limiting block 83... 3. When not in contact with the adjacent second limiting ring 85, the rotating shaft 82 drives the adjacent second limiting ring 85 to rotate clockwise (from front to back) through the adjacent fifth limiting block 83. The second limiting ring 85 pulls the elastic rope 86, and the elastic rope 86 is stretched. While the second limiting ring 85 rotates, it drives the tension rope 89 to move (initially, the limiting pin 87 passes through the adjacent rotating frame 81 and the fixed shaft 8 to fix the rotating frame 81). The tension rope 89 drives the adjacent limiting pin 87 to move, so that the limiting pin 87 is disengaged from the adjacent fixed shaft 8. At the same time, the second tension spring 88 stores force.

[0053] After the aforementioned limiting pin 87 disengages from the adjacent fixed shaft 8, the rotating shaft 82 is limited by the adjacent fifth limiting block 83, the adjacent second limiting ring 85, and the adjacent rotating frame 81. The rotating shaft 82 is fixed to the adjacent rotating frame 81, and the rotating shaft 82 no longer rotates. The traction rope 72 drives the rotating frame 81 to rotate through the rotating shaft 82, causing the rotating frame 81 to drive the fixed plate 810 to rotate. The fixed plate 810 presses against the adjacent third limiting rod 811. The third limiting rod 811 drives the sixth limiting block 91 to move and presses against the adjacent fourth spring 9, causing the two adjacent sixth limiting blocks 91 to gradually approach each other and contact the traction rope 72 in the middle of the two adjacent sixth limiting blocks 91. After contact, the two sixth limiting blocks 91 move upward with the adjacent traction rope 72 under the action of friction until the two sixth limiting blocks 91 enter the... The three limiting rings 92 are inside the car and compress the two sixth limiting blocks 91, fixing the sixth limiting blocks 91 to the traction rope 72. The traction rope 72 drives the third limiting ring 92 to move upward through the sixth limiting blocks 91. The third limiting ring 92 drives the third fixed block 75 to move upward, and at the same time pulls the first damping rod 93. The first damping rod 93 decelerates the third fixed block 75, thereby reducing the falling speed of the car 12. When the lower side of the third fixed block 75 is above the second fixed block 74, the third fixed block 75 drives the second fixed block 74 to move upward. At the same time, the second damping rod 94 is stretched, which slows down the movement of the second fixed block 74, decelerates the car 12, and stops the car 12 to prevent it from falling. During subsequent maintenance, the parts near the second fixed block 74 are reset.
