Description

Technical Field

[0001] The invention relates to a translation mechanism for a cableway car door, belonging to the technical field of cableways. Background Art

[0002] Cableway generally refers to a cable car, which is a transport machine that uses a steel wire rope to pull the carriage along a track laid on the ground with a certain slope to lift or lower people and goods. It is mostly used as a means of transportation in industrial and mining areas, cities or scenic tourist areas. It is a general term or general name for equipment that uses steel rope traction to achieve the purpose of transporting people or goods. A cableway cabin refers to a transport cabin suspended on an aerial cableway, usually used to transport passengers or goods. In order to ensure the safety of people, a cabin door will be set on the cabin, and the opening and closing of the cabin door needs to be driven by a switch device.

[0003] For example, the Chinese utility model patent with the announcement number CN201695842U discloses an automatic opening and closing device for a passenger ropeway car door. The device comprises an opening and closing door mechanism (25) connected to the car door (1) and a trigger mechanism (24) fixed to the car. The trigger mechanism (24) is connected to the opening and closing door mechanism (25) via a flexible shaft (2). The utility model uses the curved surface of the opening and closing door specially provided on the ropeway to trigger the trigger roller on the utility model to drive the trigger rod to rotate a certain angle. The trigger rod drives the flexible shaft to drive the opening and closing door mechanism to operate, thereby realizing the automatic opening or closing of the car door.

[0004] The above solution has the following shortcomings in actual use: 1. This solution uses multiple connecting rods and rocker arms to open and close the hanging car door. In actual use, the hanging car door will swing when opening and closing, so the opening and closing of the hanging car door will occupy additional external space and may injure people.

[0005] This solution does not have the function of preventing rigid pinching. When closing the cabin door, people may be pinched by rigid pinching, which reduces the safety.

[0006] The emergency method of this solution is single. In actual use, if the flexible shaft is stuck, the trigger mechanism is stuck, or other failures occur that cause the flexible shaft to be unable to move, it is difficult to open the door in an emergency, and it cannot be applied to various emergency situations.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-15 , the present invention provides a technical solution: A translation mechanism for a cableway car door includes a load-bearing main body assembly, which includes a lower mounting plate 1. An upper mounting plate 2 is provided above the lower mounting plate 1. During use, the lower mounting plate 1 needs to be installed above the skylight of the car, and the upper mounting plate 2 needs to be installed on the lower side of the top of the car. Several connecting columns 3 are fixed between the lower mounting plate 1 and the upper mounting plate 2, and several special-shaped holes are provided on one side of the lower mounting plate 1 and the upper mounting plate 2.

[0027] In order to enable the two cabin doors to be opened and closed horizontally, Figures 2 to 3 、 Figure 5 、 Figure 15 As shown, a bidirectional translation assembly is provided inside the bearing body assembly, and the bidirectional translation assembly is used to enable the two hanging car doors to move in opposite directions. The bidirectional translation assembly is connected to the two hanging car doors, and the bidirectional translation assembly includes a main synchronous belt 5. Two rotating shafts 4 are rotatably connected between the lower mounting plate 1 and the upper mounting plate 2. A main synchronous wheel 6 is fixed on the outer periphery of the rotating shaft 4. The main synchronous wheel 6 is connected to the inner side of the main synchronous belt 5 through meshing transmission. An upper moving frame 7 and a lower moving frame 8 are fixed on the outer periphery of the main synchronous belt 5. The upper moving frame 7 is an L-shaped structure, and the lower moving frame 8 is a T-shaped structure. One side of the upper moving frame 7 and the lower moving frame 8 is fixed with a clamp seat in turn. 10. Clamp 11. The main synchronous belt 5 is fixed between the clamp seat 10 and the clamp plate 11. A connecting hole 9 is provided on one side of the upper movable frame 7 and the lower movable frame 8. The upper movable frame 7 and the lower movable frame 8 are respectively connected to the two hanging car doors. When the upper movable frame 7 and the lower movable frame 8 are connected to the hanging car doors, they need to be connected through the connecting holes 9 and bolts. When the rotating shaft 4 rotates, the main synchronous belt 5 can be driven to move through the main synchronous wheel 6. When the main synchronous belt 5 moves, the upper movable frame 7 and the lower movable frame 8 can be moved away from or close to each other, and the upper movable frame 7 and the lower movable frame 8 can be made to perform reverse translation movement, thereby enabling the two hanging car doors to synchronously translate in reverse.

[0028] In order to ensure the safety of people in the car, a one-way locking assembly is provided on one side of the speed change connection assembly. The one-way locking assembly is used to prevent the two car doors from being accidentally pushed open during closing. The one-way locking assembly includes a moving rod, a rotating link 12, a hollow shaft 28, a dual-purpose limiter and an emergency assembly. The hollow shaft 28 is rotatably connected between the lower mounting plate 1 and the upper mounting plate 2, and the rotating link 12 is fixed on the outer periphery of the hollow shaft 28.

[0029] The movable rod is used to prevent the cabin door from being rigidly clamped when closing, such as Figure 6 、 Figure 10 、 Figure 11As shown, the movable rod is hinged with the rotating connecting rod 12, and the movable rod includes a rack rod 16, one end of the rack rod 16 is provided with a telescopic slot, and a core shaft 17 is slidably provided on the inner side of the telescopic slot. One end of the core shaft 17 is rotatably connected to the lower side of the rotating connecting rod 12, and a limiting hole is provided on one side of the rack rod 16. The limiting hole is connected to the telescopic slot, and a limiting rod 18 is fixed on one side of the core shaft 17. The limiting rod 18 is located on the inner side of the limiting hole. The limiting rod 18 can prevent the core shaft 17 from falling out. A retaining ring 19 is provided on the outer periphery of 7 through a threaded connection, and a main spring 20 is fixed between one side of the retaining ring 19 and one end of the rack rod 16. Before use, it is necessary to rotate and adjust the position of the retaining ring 19 to adjust the initial preload force of the main spring 20. The main spring 20 can make the core shaft 17 and the rack rod 16 elastically transmitted, so that the two hanging car doors have a small amount of elastic translation range, so when closing the door, the two hanging car doors will not rigidly clamp people, and have higher safety.

[0030] In order to make the rack bar 16 drive the rotating shaft 4 to rotate when it moves, Figure 3 、 Figure 6 、 Figure 10 、 Figure 13 As shown, a speed change connection assembly is provided on one side of the bidirectional translation assembly, and the speed change connection assembly includes a speed change shaft 13, which is rotatably connected between the lower mounting plate 1 and the upper mounting plate 2. The outer periphery of the speed change shaft 13 is connected to the outer periphery of a rotating shaft 4 through a synchronous belt and a synchronous wheel. The speed of the speed change shaft 13 is lower than the speed of the rotating shaft 4. A gear 14 is fixed on the outer periphery of the speed change shaft 13, and a double fork seat 15 is rotatably provided on the outer periphery of the speed change shaft 13. The double fork seat 15 is a U-shaped structure. The double fork seat 15 includes two L-shaped seats, and the two L-shaped seats form a U-shaped structure. Double fork seat 15, rack rod 16 slides on the inner side of double fork seat 15, rack rod 16 and gear 14 are connected by meshing transmission. When rack rod 16 moves, rack rod 16 will slide on the inner side of double fork seat 15, and rack rod 16 can drive gear 14 and speed change shaft 13 to rotate. When speed change shaft 13 rotates, it can drive a rotating shaft 4 to rotate through synchronous belt and synchronous wheel. The rotation of rotating shaft 4 can drive the car door to open or close, which can make the moving rod as part of the transmission link, and then make the main spring 20 play the role of preventing rigid clamping.

[0031] In order to ensure that there is no gap between the two car doors after closing, Figure 6 、 Figure 7As shown, a bottom limit assembly is provided on one side of the rack rod 16, and the bottom limit assembly includes a limit frame 25, which is fixed between the lower mounting plate 1 and the upper mounting plate 2, and a third threaded hole is provided on one side of the limit frame 25, and a third stop head 26 is provided on the inner side of the third threaded hole through a threaded connection. Before use, the third stop head 26 needs to be adjusted to a suitable position, and a positioning nut 27 is provided on the outer periphery of the third stop head 26 through a threaded connection. After the position of the third stop head 26 is adjusted, the third stop head 26 is locked by the positioning nut 27, and the positioning nut 27 contacts the limit frame 25. The other end of the rack rod 16 is an arc structure. When the two car doors are in the closed state, as shown in FIG. Figure 6 As shown, the third stop 26 can contact the rack rod 16, and the third stop 26 contacts one end of the rack rod 16 which is an arc-shaped structure. The third stop 26 can limit one end of the rack rod 16, thereby preventing the rack rod 16 from failing to reach the predetermined position due to the tension of the main spring 20, so that there will be no gap between the two car doors after the car doors are closed.

[0032] In order to ensure that the cabin door will not be opened by mistake, Figure 3 、 Figure 4 、 Figure 9 As shown, the dual-purpose limiter is used to limit the rotating link 12 in two directions, specifically: when the car door is pushed by mistake in the closed state, the dual-purpose limiter can prevent the rotating link 12 from rotating, and when the car door is opened, the dual-purpose limiter can determine the stop position of the two car doors. The dual-purpose limiter includes a limit seat 21, which is fixed between the lower mounting plate 1 and the upper mounting plate 2. One side of the limit seat 21 is provided with a first threaded hole, and the inner side of the first threaded hole is provided with a first stop head 22 through a threaded connection, and the other side of the limit seat 21 is provided with a second threaded hole, and the second stop head 22 is provided with a second threaded hole. The inner sides of the two threaded holes are provided with a second stopper 23 through a threaded connection. Before use, it is necessary to rotate and adjust the positions of the first stopper 22 and the second stopper 23. A locking nut 24 is provided on the outer periphery of the first stopper 22 and the second stopper 23 through a threaded connection. After the positions of the first stopper 22 and the second stopper 23 are determined, the first stopper 22 and the second stopper 23 are locked by the locking nut 24. The locking nut 24 contacts the limit seat 21, and the rotating connecting rod 12 can contact the first stopper 22 and the second stopper 23. When the car door is in the closed state, such as Figure 6As shown, the rotating connecting rod 12 will be close to the first stopper 22. At this time, if the car door is pushed by mistake, the thrust received by the car door can be converted into the rotational force of the speed change shaft 13 and the gear 14, and the rotational force of the gear 14 can be converted into the translational force of the rack rod 16 and the core shaft 17. At this time, the translational force of the core shaft 17 can only act on the first stopper 22 through the rotating connecting rod 12, because the hinge point of the core shaft 17 and the rotating connecting rod 12 is located on one side of the line connecting the center point of the hollow shaft 28 and the meshing point of the rack rod 16 and the gear 14, such as: The center point of the circle of the shaft 28 is point A, the hinge point of the core shaft 17 and the rotating connecting rod 12 is point B, and the meshing point of the rack rod 16 and the gear 14 is point C. When the car door is in the closed state, point B is on one side of the line connecting points AC. Due to the existence of the elastic force of the main spring 20, point B cannot cross the line connecting points AC to reach the other side of the line connecting points AC. Therefore, the rack rod 16 and the core shaft 17 cannot move at this time, thereby realizing one-way locking, which can prevent the car door from being accidentally pushed open during closing, so that the car door has an anti-accidental opening function.

[0033] In order to be able to close the cabin door by itself, Figure 3 、 Figure 6 As shown, a driving assembly is provided on one side of the one-way locking assembly, and the driving assembly is used to drive the car door to open and close. The driving assembly includes a rotating seat 36, and the rotating seat 36 is rotatably connected between the lower mounting plate 1 and the upper mounting plate 2. A mounting groove is provided on one side of the rotating seat 36, and a guide sleeve 39 is fixedly provided on the inner side of the mounting groove. A flexible shaft 37 is slidably connected in the guide sleeve 39, and a connecting head 38 is fixedly provided at one end of the flexible shaft 37. The other end of the flexible shaft 37 is connected to a trigger mechanism, and the trigger mechanism is used to control the flexible shaft 37 to telescopically move. The connecting head 38 is located inside the shaft seat 35, and a circular hole is provided on the upper side of the connecting head 38. The pin shaft 34 is disassembled and plugged into the inner side of the circular hole. When the car enters the station, the flexible shaft 37 can be controlled to retract by the trigger mechanism. When the flexible shaft 37 retracts, it can drive the rotating connecting rod 12 to rotate. At this time, the main spring 20 will be compressed, and point B will gradually approach and cross the line connecting point AC. When points A, B and C When the points are on a straight line, the main spring 20 is compressed to the shortest point, and then the rotating link 12 continues to rotate, and the main spring 20 will extend. When the main spring 20 extends to the longest point, that is, when the limit rod 18 contacts the inner wall of the limit hole, the rotating movement of the rotating link 12 can drive the core shaft 17 and the rack rod 16 to move. When the rack rod 16 moves, it can drive the speed change shaft 13 to rotate. The rotation of the speed change shaft 13 can drive the rotating shaft 4 to rotate, and then drive the car door to open. During this period, the rotating link 12 also gradually approaches the second stop head 23. When the rotating link 12 stops after contacting the second stop head 23, the automatic door opening can be completed. When the car needs to close the car door when leaving the station, the trigger mechanism can be used to control the soft shaft 37 to extend. The principle of the trigger mechanism controlling the extension and retraction of the soft shaft 37 is the same as the cited document, and will not be repeated in this article, so that the rotating link 12 contacts the first stop head 22. Figure 6 As shown, automatic door closing can be completed.

[0034] In another embodiment, a push rod is used instead of the flexible shaft 37 and the guide sleeve 39.

[0035] When special circumstances occur, such as when a driving component fails, a driving component is stuck, a trigger mechanism fails, and the like, and the door needs to be opened from inside the cabin, the cabin door is manually opened and closed by the emergency assembly. In this embodiment, the driving component is a flexible shaft 37, such as Figure 8 、 Figure 9 As shown, the emergency component includes a trigger shaft 29, which is slidably connected to the inner side of the hollow shaft 28. A force groove 30 is provided on the lower side of the trigger shaft 29. A fixed cover 31 is fixed on the inner side of the hollow shaft 28. The fixed cover 31 is connected to the inner side of the hollow shaft 28 by threading. A trigger spring 32 is fixed between the fixed cover 31 and the trigger shaft 29. A lifting hole is provided on one side of the hollow shaft 28. A lifting plate 33 is fixed on the outer periphery of the trigger shaft 29. The lifting plate 33 slides on the inner side of the lifting hole. A through hole is provided on the upper side of the lifting plate 33. A pin 34 is rotatably provided on the inner side of the through hole. A shaft seat 35 is fixed on the lower side of the rotating connecting rod 12. The shaft seat 35 is a U-shaped structure. The upper side of the rotating connecting rod 12 and the upper and lower sides of the shaft seat 35 are connected. There are shaft holes on both sides, and the pin shaft 34 is disassembled and plugged into the inner side of the shaft hole. When the car door needs to be opened or closed manually, you only need to use a specific wrench to connect to the lower end of the trigger shaft 29, and make the wrench stuck in the force groove 30, and then press the trigger shaft 29 to make the wrench close to the hollow shaft 28. At this time, the trigger shaft 29, the lifting plate 33 and the pin shaft 34 will rise, and the trigger spring 32 will be compressed. At this time, the pin shaft 34 will be disengaged from the connector 38, and then the wrench is rotated to drive the trigger shaft 29 and the hollow shaft 28 to rotate. The hollow shaft 28 can be rotated to manually open or close the car door. In the event of a trigger mechanism failure or the soft shaft 37 being stuck, the car door can be manually opened or closed, and then maintenance can be carried out under appropriate circumstances.

[0036] The working process of this embodiment is: when the car door needs to be opened, the car door is automatically opened by cooperating with the driving component, the one-way locking component, the speed change connection component and the two-way translation component; when the car door needs to be closed, the car door is automatically closed by cooperating with the driving component, the one-way locking component, the speed change connection component and the two-way translation component; and during the closing of the car door, rigid pinching prevention can be achieved by moving the rod; after closing the car door, accidental opening prevention can be achieved by the one-way locking component, and then automatic opening and closing of the car door is achieved by cooperating with the driving component, the one-way locking component, the speed change connection component and the two-way translation component; when special circumstances require manual opening and closing of the car door, the emergency component is used to manually open or close the car door.
