Description

Technical Field

[0001] This invention relates to a sliding mechanism for cableway gondola doors, belonging to the field of cableway technology. Background Technology

[0002] Cableways generally refer to cable cars. Cable cars are transport machines that use a drive motor to pull steel cables, which pull the cabins along a track laid on the ground with a certain slope. They are used to lift or lower people and goods. They are mostly used as transportation in industrial and mining areas, cities, or scenic tourist areas. They are a general term or common name for equipment that uses steel cables to achieve the purpose of transporting people or goods. Cableway gondolas refer to the transport cabins suspended on the aerial cableway. They are usually used to transport passengers or goods. In order to ensure the safety of personnel, gondolas are equipped with gondola doors, and the opening and closing of the gondola doors need to be driven by a switch device.

[0003] For example, Chinese utility model patent CN201695842U discloses an automatic opening and closing device for passenger cableway gondola doors. It includes an opening and closing mechanism (25) connected to the gondola door (1) and a triggering mechanism (24) fixed to the gondola. The triggering mechanism (24) is connected to the opening and closing mechanism (25) via a flexible shaft (2). This utility model uses a curved surface specially designed on the cableway to trigger a trigger roller on the device, which rotates a trigger rod by an angle. The trigger rod then drives the flexible shaft to activate the opening and closing mechanism, thus automatically opening or closing the gondola door…

[0004] The above solution has the following shortcomings in practical use:

[0005] 1. This solution uses multiple linkages and rocker arms to open and close the gondola door. In actual use, the gondola door will swing when it is opened and closed, so the opening and closing of the gondola door will occupy additional external space and may injure people.

[0006] 2. This solution does not have the function of preventing rigid pinching injuries. When closing the hoist door, there may be a situation where people are rigidly pinched and injured, which is a low safety level.

[0007] 3. This solution has only one emergency method. In actual use, if there is a problem such as the flexible shaft jamming, the trigger mechanism jamming, or other malfunctions that prevent the flexible shaft from moving, it will be difficult to open the door in an emergency and it cannot be applied to a variety of emergency situations.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0045] Please see Figure 1-15 The present invention provides a technical solution:

[0046] A sliding mechanism for a cable car gondola door includes a load-bearing main assembly. The load-bearing main assembly includes a lower mounting plate 1 and an upper mounting plate 2 above the lower mounting plate 1. During use, the lower mounting plate 1 needs to be installed above the skylight of the gondola, and the upper mounting plate 2 needs to be installed on the lower side of the top of the gondola. Several connecting columns 3 are fixedly provided between the lower mounting plate 1 and the upper mounting plate 2. Several irregular holes are provided on one side of the lower mounting plate 1 and the upper mounting plate 2.

[0047] In order to enable the two hanging cabin doors to slide open and close, such as Figures 2 to 3 , Figure 5 , Figure 15As shown, the main supporting component has a bidirectional translation component inside, which enables the two gondola doors to move in opposite directions. The bidirectional translation component is connected to the two gondola doors and 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 pulley 6 is fixed on the outer periphery of the rotating shaft 4. The main synchronous pulley 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 has an L-shaped structure, and the lower moving frame 8 has a T-shaped structure. A clamp is fixed on one side of the upper moving frame 7 and the lower moving frame 8 in sequence. 10. Clamping plate 11, main synchronous belt 5 is fixed between clamping seat 10 and clamping plate 11. Connecting holes 9 are provided on one side of upper moving frame 7 and lower moving frame 8. Upper moving frame 7 and lower moving frame 8 are respectively connected to two gondola doors. When upper moving frame 7 and lower moving frame 8 are connected to gondola doors, they need to be connected through connecting holes 9 and bolts. When rotating shaft 4 rotates, it can drive main synchronous belt 5 to move through main synchronous wheel 6. When main synchronous belt 5 moves, it can make upper moving frame 7 and lower moving frame 8 move away from each other or move closer to each other, so that upper moving frame 7 and lower moving frame 8 can perform reverse translational movement, thereby enabling the two gondola doors to move synchronously in the opposite direction.

[0048] To ensure the safety of personnel inside the gondola, a one-way locking component is provided on one side of the transmission connection assembly. The one-way locking component is used to prevent the two gondola doors from being accidentally pushed open during closing. The one-way locking component includes a moving rod, a rotating connecting rod 12, a hollow shaft 28, a dual-purpose limiter, and an emergency component. The hollow shaft 28 is rotatably connected between the lower mounting plate 1 and the upper mounting plate 2, and the rotating connecting rod 12 is fixed on the outer periphery of the hollow shaft 28.

[0049] The movable rod is used to prevent personnel from being rigidly pinched when the gondola door closes, such as... Figure 6 , Figure 10 , Figure 11 As shown, the moving rod and the rotating connecting rod 12 are hinged. The moving rod includes a rack 16, one end of which has a telescopic groove. A spindle 17 is slidably mounted inside the telescopic groove. One end of the spindle 17 is rotatably connected to the lower side of the rotating connecting rod 12. A limiting hole is provided on one side of the rack 16, which communicates with the telescopic groove. A limiting rod 18 is fixedly mounted on one side of the spindle 17, located inside the limiting hole. The limiting rod 18 can prevent the spindle 17 from coming out. A retaining ring 19 is provided on the outer periphery of 7 via a threaded connection. A main spring 20 is fixed between one side of the retaining ring 19 and one end of the rack 16. Before use, the position of the retaining ring 19 needs to be rotated and adjusted to adjust the initial preload of the main spring 20. The main spring 20 enables the spindle 17 and the rack 16 to be elastically transmitted, allowing the two hanging doors to have a small range of elastic translation. Therefore, when closing the doors, the two hanging doors will not rigidly pinch and injure personnel, providing a high level of safety.

[0050] In order for the rack 16 to drive the rotating shaft 4 to rotate during movement, such as Figure 3 , Figure 6 , Figure 10 , Figure 13 As shown, a speed-changing connection assembly is provided on one side of the bidirectional translation component. The speed-changing connection assembly includes a speed-changing shaft 13, which is rotatably connected between the lower mounting plate 1 and the upper mounting plate 2. The outer periphery of the speed-changing shaft 13 is connected to the outer periphery of a rotating shaft 4 via a synchronous belt and a synchronous pulley. The rotational speed of the speed-changing shaft 13 is less than the rotational speed of the rotating shaft 4. A gear 14 is fixedly provided on the outer periphery of the speed-changing shaft 13, and a double fork seat 15 is rotatably provided on the outer periphery of the speed-changing shaft 13. The double fork seat 15 has a U-shaped structure and includes two L-shaped seats, which together form a U-shaped structure. The rack and pinion 16 slides inside the double fork seat 15. The rack and pinion 16 is connected to the gear 14 through meshing transmission. When the rack and pinion 16 moves, it slides inside the double fork seat 15. At the same time, the rack and pinion 16 can drive the gear 14 and the gear change shaft 13 to rotate. When the gear change shaft 13 rotates, it can drive a rotating shaft 4 to rotate through the synchronous belt and synchronous pulley. The rotation of the rotating shaft 4 can drive the cabin door to open or close. This allows the moving rod to be part of the transmission link, thereby enabling the main spring 20 to play a role in preventing rigid pinching.

[0051] To ensure that there is no gap between the two gondola doors after they are closed, such as Figure 6 , Figure 7 As shown, a bottom limiting component is provided on one side of the rack 16. The bottom limiting component includes a limiting frame 25, which is fixed between the lower mounting plate 1 and the upper mounting plate 2. A third threaded hole is provided on one side of the limiting frame 25. A third stop 26 is provided on the inner side of the third threaded hole via a threaded connection. Before use, the third stop 26 needs to be adjusted to a suitable position. A positioning nut 27 is provided on the outer circumference of the third stop 26 via a threaded connection. After the position of the third stop 26 is adjusted, the positioning nut 27 is used to lock the third stop 26. The positioning nut 27 contacts the limiting frame 25. The other end of the rack 16 has an arc-shaped structure. When the two hanging doors are closed, as shown... Figure 6 As shown, the third stop 26 can contact the rack rod 16, and the third stop 26 contacts the arc-shaped end of the rack rod 16. The third stop 26 can restrict one end of the rack rod 16, which can prevent 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 rack doors after the hoist doors are closed.

[0052] To ensure that the hanging room door is not accidentally pushed open, such as Figure 3 , Figure 4 , Figure 9As shown, the rotating connecting rod 12 is bidirectionally limited by a dual-purpose limiting component. Specifically, when the gondola door is accidentally pushed while closed, the dual-purpose limiting component prevents the rotating connecting rod 12 from rotating. When the gondola door is open, the dual-purpose limiting component determines the stopping position of both gondola doors. The dual-purpose limiting component includes a limiting seat 21, which is fixed between the lower mounting plate 1 and the upper mounting plate 2. One side of the limiting seat 21 has a first threaded hole, and the inner side of the first threaded hole is provided with a first stop 22 via a threaded connection. The other side of the limiting seat 21 has a second threaded hole. The inner side of the two threaded holes is provided with a second stop 23 via a threaded connection. Before use, the positions of the first stop 22 and the second stop 23 need to be adjusted by rotation. Locking nuts 24 are threadedly connected to the outer circumferences of the first stop 22 and the second stop 23. After the positions of the first stop 22 and the second stop 23 are determined, they are locked by the locking nuts 24. The locking nuts 24 contact the limit seat 21, allowing the rotating connecting rod 12 to contact the first stop 22 and the second stop 23. When the hoist door is closed, such as... Figure 6 As shown, the rotating linkage 12 will be pressed against the first stop 22. At this time, if the hoist door is accidentally pushed, the pushing force on the hoist door can be converted into the rotational force of the transmission shaft 13 and gear 14. The rotational force of gear 14 can be converted into the translational force of rack 16 and spindle 17. At this time, the translational force of spindle 17 can only act on the first stop 22 through the rotating linkage 12, because the hinge point between spindle 17 and rotating linkage 12 is located on one side of the line connecting the center point of hollow shaft 28 and the meshing point of rack 16 and gear 14. For example: hollow shaft 28 Point A is the center of shaft 28, point B is the hinge point between spindle 17 and rotating connecting rod 12, and point C is the meshing point between rack 16 and gear 14. When the hoisting door is closed, point B is on one side of the line connecting points A and B. Due to the elasticity of the main spring 20, point B cannot cross the line connecting points A and B to reach the other side of the line connecting points A and B. Therefore, rack 16 and spindle 17 cannot move at this time, thus achieving one-way locking and preventing the hoisting door from being accidentally pushed open during closing, giving the hoisting door an anti-accidental opening function.

[0053] In order to be able to close the hanging room door by itself, such as Figure 3 , Figure 6As shown, a drive assembly is provided on one side of the one-way locking component. The drive assembly is used to drive the opening and closing of the gondola door. The drive assembly includes a rotating seat 36, which 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. A guide sleeve 39 is fixedly provided inside the mounting groove. A flexible shaft 37 is slidably connected inside the guide sleeve 39. A connector 38 is fixedly provided at one end of the flexible shaft 37. A trigger mechanism is connected to the other end of the flexible shaft 37. The trigger mechanism is used to control the extension and retraction of the flexible shaft 37. The connector 38 is located inside the shaft seat 35. A round hole is provided on the upper side of the connector 38. The pin 34 is disassembled and inserted into the inner side of the round hole. When the gondola enters the station, the trigger mechanism can control the flexible shaft 37 to retract. 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 points A, B and C. When the points are on a straight line, the main spring 20 is compressed to its shortest length. Then, the rotating link 12 continues to rotate, and the main spring 20 extends. When the main spring 20 extends to its longest length, that is, when the limit rod 18 contacts the inner wall of the limit hole, the rotational movement of the rotating link 12 can drive the spindle 17 and the rack 16 to move. When the rack 16 moves, it can drive the gear shaft 13 to rotate. The rotation of the gear shaft 13 can drive the rotating shaft 4 to rotate, which in turn can drive the gondola door to open. During this period, the rotating link 12 also gradually approaches the second stop 23. When the rotating link 12 contacts the second stop 23 and stops, the automatic door opening can be completed. When the gondola needs to close the gondola door when leaving the station, the flexible shaft 37 can be extended by the trigger mechanism when the gondola leaves the station. The principle of the trigger mechanism controlling the extension and retraction of the flexible shaft 37 is the same as that in the cited document, and will not be repeated here. This allows the rotating link 12 to contact the first stop 22, such as Figure 6 As shown, the door will close automatically.

[0054] In another embodiment, a push rod is used instead of the flexible shaft 37 and the guide sleeve 39.

[0055] In special circumstances, such as drive component failure, drive component jamming, or trigger mechanism failure, when it is necessary to open the door from inside the gondola, the gondola door can be manually opened and closed using the emergency component. In this embodiment, the drive component is a flexible shaft 37. Figure 8 , Figure 9As shown, the emergency assembly includes a trigger shaft 29, which is slidably connected to the inner side of a hollow shaft 28. A force-receiving groove 30 is provided on the lower side of the trigger shaft 29. A fixing cover 31 is fixedly provided on the inner side of the hollow shaft 28, and the fixing cover 31 is threadedly connected to the inner side of the hollow shaft 28. A trigger spring 32 is fixedly provided between the fixing 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 fixedly provided on the outer periphery of the trigger shaft 29, and the lifting plate 33 slides inside the lifting hole. A through hole is provided on the upper side of the lifting plate 33, and a pin 34 is rotatably provided inside the through hole. A bearing seat 35 is fixedly provided on the lower side of the rotating connecting rod 12. The bearing seat 35 has a U-shaped structure. The upper side of the rotating connecting rod 12 and the upper and lower sides of the bearing seat 35 are connected. Both sides are provided with shaft holes, and the pin 34 is disassembled and inserted into the inner side of the shaft hole. When it is necessary to manually open or close the hoist door, simply use a specific wrench to attach to the lower end of the trigger shaft 29, so that the wrench is locked in the force groove 30, and then press down the trigger shaft 29 so that the wrench is close to the hollow shaft 28. At this time, the trigger shaft 29, the lifting plate 33 and the pin 34 will rise, the trigger spring 32 will be compressed, and the pin 34 will disengage from the connector 38. Then rotate the wrench to drive the trigger shaft 29 and the hollow shaft 28 to rotate. The rotation of the hollow shaft 28 can manually open or close the hoist door. The hoist door can be manually opened or closed in the event of trigger mechanism failure or jamming of the flexible shaft 37, and then maintenance can be carried out under appropriate circumstances.

[0056] The workflow of this embodiment is as follows: When the gondola door needs to be opened, the drive component, one-way locking component, speed-changing connection component, and bidirectional translation component work together to automatically open the gondola door. When the gondola door needs to be closed, the drive component, one-way locking component, speed-changing connection component, and bidirectional translation component work together to automatically close the gondola door. Moreover, during the closing of the gondola door, rigid pinching injury can be prevented by moving the rod. After the gondola door is closed, accidental opening can be prevented by the one-way locking component. Thus, the automatic opening and closing of the gondola door is achieved through the cooperation of the drive component, one-way locking component, speed-changing connection component, and bidirectional translation component. When a special situation occurs that requires manual opening and closing of the gondola door, the emergency component can be used to manually open or close the gondola door.

[0057] 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.
