Description

Technical Field

[0001] This invention relates to the field of elevator equipment technology, specifically to a right-angle door elevator. Background Technology

[0002] A typical elevator opens so that a passenger enters from one door direction and exits from the same door after reaching the destination floor. There are also elevators with doors opening in both directions. However, due to building structure limitations, some elevators with two entrances have their center lines intersecting at a 90° angle. Passengers enter the elevator from the door in the positive direction and exit from a different direction. This is called a right-angle door elevator. The existing right-angle door elevator car guide rails are usually arranged diagonally within the elevator car. Elevators of the same size often require a larger shaft to complete the layout and installation. The overall elevator structure lacks a counterweight, making the elevator prone to swaying and unstable when there is an uneven load inside the elevator car. Furthermore, the safety protection mechanisms of existing right-angle door elevators are mostly installed on the elevator guide rails or at the hinges of the steel cables to achieve emergency stops. However, the existing safety protection mechanisms have certain defects in emergency braking. When the elevator experiences severe vibrations, the safety clamps are prone to slippage and cannot provide safety protection. In addition, some elevators stop immediately after emergency braking. If the elevator stops immediately after a rapid descent, it can easily cause injury to people inside the elevator car, posing a certain safety hazard. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1 to 9This invention provides a technical solution: a right-angle door elevator, comprising a car body 1, a car top assembly 11, and a car wall assembly 12. The car top assembly 11 is fixedly connected to the upper end of the car body 1, and the car wall assembly 12 is fixedly connected to the side of the car body 1.

A deceleration assembly is arranged on two adjacent sides of the car body 1. The deceleration assembly does not contact the car body 1. The guide rails 3 and the deceleration assembly are both installed in the elevator shaft and are fixedly connected to the side wall of the elevator shaft. The elevator shaft should be made of reinforced concrete. For earthen structures, when the user's civil engineering is a ring beam structure, a 200mm high concrete frame should be set according to the guide rail support spacing, and a 200mm high concrete beam with the same width as the shaft should be set on the upper edge of each floor door opening. The lower end of the car body 1 is fixedly connected to a cross-shaped connecting frame 4, and the lower end of the cross-shaped connecting frame 4 is fixedly connected to a regular polygonal column 5. The lower end of the regular polygonal column 5 is installed with a base 6. Four deceleration mechanisms and four emergency braking mechanisms are installed in a circumferential array inside the base 6. The four deceleration mechanisms and four emergency braking mechanisms are alternately arranged on the base 6. A counterweight is set on the back side of the car. The elevator traction rope is distributed on the rear and front sides of the shaft so that the overall force of the lifting point is centered and matches the center of gravity of the car.

[0018] Please see Figure 1 , Figure 2 and Figure 4 The backpack frame 2 includes an upper beam assembly 21 disposed on the upper end of the car body 1, a spreader beam assembly wide wheel 22 disposed on the lower end of the upper beam assembly 21, two upright beam assemblies 23 symmetrically disposed on the sides of the upper beam assembly 21, and a cable tray reinforcement plate 24 disposed on the lower end of the upright beam assembly 23. The upper beam assembly 21 and the cable tray reinforcement plate 24 are both fixedly connected to the upright beam assembly 23. The upper beam assembly 21 is fixedly connected to the spreader beam assembly wide wheel 22. The spreader beam assembly wide wheel 22 is fixedly connected to the car top assembly 11 through a connecting plate 25. The upper beam assembly 21 is symmetrically and fixedly connected to two high-strength threaded rods 26 on the side away from the vertical beam assembly 23. The lower ends of the two high-strength threaded rods 26 are fixedly connected to the lower end of the car body 1. The backpack frame 2 is fixedly connected to the car body 1. When the car and car frame are assembled, four corner structural components are used, with two vertical beam assemblies 23 on the rear side and two high-strength threaded rods 26 on the front side, forming a frame shape while enhancing the load-bearing capacity. This makes the elevator safe, easy to manufacture and install, quiet, and comfortable.

[0019] Please see Figure 1 , Figure 5 , Figure 6 and Figure 8The mitigation assembly includes two limiting vertical plates 32 disposed on the side of the car body 1, and multiple high-strength elastic ropes 33 disposed between the two limiting vertical plates 32. The multiple high-strength elastic ropes 33 are equidistant from top to bottom, and the two ends of the high-strength elastic ropes 33 are fixedly connected to the two limiting vertical plates 32. The limiting vertical plates 32 are fixedly connected to the side wall of the elevator shaft. The high-strength elastic ropes 33 are made of high molecular weight polyethylene ropes. The two mitigation assemblies are disposed on both sides of the car body 1 where there are no elevator doors.

[0020] Please see Figure 1 , Figure 6 , Figure 7 and Figure 9 The cross-shaped connecting frame 4 has four speed detectors 41 installed in a circular array. Two rollers 42 are installed at each of the four ends of the cross-shaped connecting frame 4. The side of the guide rail 3 has a groove, and the rollers 42 are rolled in the groove. When the elevator is running up and down, the cross-shaped connecting frame 4 drives the rollers 42 to move up and down. The rollers 42 roll up and down along the groove of the guide rail 3, so that the elevator can run up and down stably.

[0021] Please see Figure 6 , Figure 7 and Figure 9 The side members of the regular polygonal column 5 are provided with multiple positioning holes 51 in a circumferential array. The lower end of the regular polygonal column 5 is fixedly connected with multiple gas springs 52 in a circumferential array. The side of the regular polygonal column 5 is fixedly connected with four guide blocks 53 and four extrusion plates 54 in a circumferential array. The four guide blocks 53 and four extrusion plates 54 are alternately distributed. The upper end of the base 6 is provided with a regular polygonal groove 61. The regular polygonal column 5 is slidably connected to the regular polygonal groove 61. The lower end of the gas spring 52 is fixedly connected to the bottom of the regular polygonal groove 61. The inner side of the regular polygonal groove 61 is provided with four guide grooves 62 and four sliding grooves 64 arranged in a circumferential array. The four guide grooves 62 and four sliding grooves 64 are alternately distributed. The inner side of the regular polygonal groove 61 is provided with four contraction grooves 63 above the four guide grooves 62. The sides of the four sliding grooves 64 are provided with extrusion grooves 65. The guide block 53 is slidably connected to the guide groove 62. The extrusion plate 54 is slidably connected to the sliding groove 64. The gas spring 52 applies elastic force to the regular polygonal column 5. When the elevator moves upward, the regular polygonal column 5 drives the guide block 53 to move upward, and the guide block 53 drives the base 6 to move upward.

[0022] Please see Figure 6 , Figure 8 and Figure 9The deceleration mechanism includes a concave plate 7 disposed in the shrinkage groove 63, two limiting rods 71 ​​symmetrically disposed on the side of the concave plate 7, a hydraulic cylinder 72 disposed on the inner side of the concave plate 7, and two safety claws 73 symmetrically disposed at both ends of the concave plate 7. The concave plate 7 is fixedly connected to the limiting rods 71 ​​and the safety claws 73 respectively. The hydraulic cylinder 72 is fixedly installed on the side of the base 6. The piston rod of the hydraulic cylinder 72 passes through the base 6 and is fixedly connected to the concave plate 7. When the regular polygonal column 5 moves downward, the limiting rods 71 ​​are inserted into the positioning holes 51 of the regular polygonal column 5, and the regular polygonal column 5 and the base 6 move up and down synchronously. The concave plate 7 is slidably connected to the contraction groove 63, and the safety claw 73 is slidably connected to the base 6. One end of the safety claw 73 passes through the base 6 and is engaged with the high-strength elastic rope 33 in the deceleration assembly. A controller is installed on the car body 1. The controller is connected to the speed detector 41 and the hydraulic cylinder 72 respectively. When the elevator experiences an abnormal rapid descent, the speed detector 41 can detect it in time and send the information to the controller. At this time, the controller receives the signal and controls the piston rod of the hydraulic cylinder 72 to retract. The piston rod drives the concave plate 7 to move into the contraction groove 63. The concave plate 7 drives the limit rod 71 to move out of the positioning hole 51 on the side of the regular polygonal column 5, so that the limit rod 7... 1. Loosen the fixation on the regular polygonal column 5. At the same time, the concave plate 7 drives the safety claw 73 to extend outward, so that the safety claw 73 engages with the high-strength elastic rope 33. Under the action of multiple high-strength elastic ropes 33, the downward movement speed of the safety claw 73 is slowed down until the safety claw 73 stops moving downward. At the same time, the base 6 slows down the downward falling speed until the base 6 stops moving downward. At this time, under the action of the gravity of the car body 1, the regular polygonal column 5, and the people in the elevator, the regular polygonal column 5 moves downward along the regular polygonal groove 61. At the same time, the regular polygonal column 5 compresses the gas spring 52. Under the action of the elastic force of the gas spring 52, the downward movement speed of the regular polygonal column 5 and the car body 1 is slowed down.

[0023] Please see Figure 1 , Figure 5 , Figure 7 and Figure 9The emergency braking mechanism includes a transmission block 8 disposed within a compression groove 65, two emergency braking toothed plates 81 symmetrically disposed on the sides of the transmission block 8, and a U-shaped spring plate 82 disposed between the two emergency braking toothed plates 81. The emergency braking toothed plates 81 are fixedly connected to the transmission block 8. The U-shaped spring plate 82 is disposed within the compression groove 65, and one side of the U-shaped spring plate 82 is fixedly connected to the transmission block 8. The upper end of the transmission block 8 and the lower end of the compression plate 54 are both sloped. The compression plate 54 is in sliding contact with the transmission block 8. Both the transmission block 8 and the emergency braking toothed plates 81 are slidably connected to the compression groove 65. One side of the emergency braking toothed plate 81 passes through the base 6 and engages with the rack plate 31. When the regular polygonal column 5 moves downward along the regular polygonal groove 61, it drives the compression plate 54 along the sliding groove 64. As the elevator slides downwards, the compression plate 54 slides down along the transmission block 8. At the same time, the compression plate 54 compresses the transmission block 8, causing the transmission block 8 to move inwards along the compression groove 65. The transmission block 8 drives the emergency brake toothed plate 81 to slide outwards along the base 6, so that the emergency brake toothed plate 81 engages with the rack plate 31, further fixing the base 6. When the gas spring 52 is compressed to the lowest end, the regular polygonal column 5 stops moving downwards. The regular polygonal column 5 drives the car body 1 to stop moving downwards. When the elevator falls rapidly, with the cooperation of the deceleration component, the gas spring 52, the deceleration mechanism and the emergency brake mechanism, the car body 1 can have a certain buffer distance during the process of stopping the fall, thereby preventing injury to the people inside the car body 1.

[0024] Working principle: The car frame is assembled using four corner structural components, two rear upright beam assemblies 23, and two high-strength threaded rods 26 on the front, forming a frame that enhances load-bearing capacity. The lower end of the car body 1 is stabilized by the cross-shaped connecting frame 4. When the car body 1 moves up and down, it drives the cross-shaped connecting frame 4 to move up and down. The cross-shaped connecting frame 4 drives the rollers 42 to roll up and down along the guide rail 3, thereby enabling the elevator to run stably up and down. This results in high overall elevator safety, ease of production and installation, quiet operation, and good comfort. When the elevator experiences an abnormal rapid descent during operation, the speed detector 41 promptly sends the abnormal descent speed information to the controller. Upon receiving the signal, the controller controls the piston rod of the hydraulic cylinder 72 to retract. The piston rod drives the concave plate 7 to move into the retraction groove 63. The concave plate 7 then moves the limit rod 71 out of the positioning hole 51 on the side of the polygonal column 5, releasing the limit rod 71 from its fixation to the polygonal column 5. At this point, the polygonal column 5 can move downwards along the base 6. Simultaneously, the concave plate 7 drives the safety claw 73 to extend outwards along the base 6, engaging with the high-strength elastic rope 33. Under the action of multiple high-strength elastic ropes 33, the downward speed of the safety claw 73 is slowed until it stops moving downwards. The safety claw 73 also slows the downward descent speed of the base 6 until it stops moving downwards. At this point, under the combined weight of the car body 1, the polygonal column 5, and the passengers inside the elevator, the polygonal column 5... The column 5 moves downward along the regular polygonal groove 61, while simultaneously compressing the gas spring 52. Under the elastic force of the gas spring 52, the downward movement speed of the regular polygonal column 5 and the car body 1 is reduced. As the regular polygonal column 5 moves downward along the regular polygonal groove 61, it drives the compression plate 54 to slide downward along the slide groove 64. When the compression plate 54 moves downward, it compresses the transmission block 8, causing the transmission block 8 to move inward along the compression groove 65. The transmission block 8 drives the emergency brake tooth plate 81 to slide outward along the base 6, so that the emergency brake tooth plate 81 engages with the rack plate 31, further fixing the base 6. When the gas spring 52 is compressed to the lowest end, the regular polygonal column 5 stops moving downward, and the regular polygonal column 5 drives the car body 1 to stop moving downward. When the elevator falls rapidly, with the cooperation of the deceleration component, the gas spring 52, the deceleration mechanism and the emergency brake mechanism, the car body 1 can have a certain buffer distance during the process of stopping the fall, thereby preventing injury to the people inside the car body 1.

[0025] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
