Description

[0001] EMERGENCY SUPPORT FOR OVERHEAD CABLE TRANSPORT SYSTEMS

[0002] TECHNICAL FIELD

[0003] The present invention relates to cableway systems and mechanisms and devices that enable the safe and continuous operation of such cableway systems when failures occur. Specifically, the present invention relates to mechanisms that reduce the impact caused by damage to a clutch and release path of vehicles traveling on the cableway, such as cabs or chairs.

[0004] DESCRIPTION OF THE STATE OF THE ART

[0005] Metrocables, also known as cable cars or cableways, are transportation systems that use cabins or chairs suspended by overhead cables to move between stations. These systems are commonly used in rural or urban areas with mountainous topography or difficult access, both for tourism and mass urban transportation. These systems have proven to be effective solutions for improving mobility in urban areas with particular topographical challenges, which is why their demand has been increasing in recent years.

[0006] Specifically, cable cars operate by suspending cabins or gondolas from overhead cables. These cables are supported by pylons or towers, located at strategic points throughout the area covered by the cable car system. Typically, in these systems, the cabins move with the cable and are secured to it by means of a clamp. In some cases, upon entering a station where passengers can board and disembark, the cabin enters a coupling and uncoupling track where the clamp separates from the cable, and the cabin slows down so that passengers can enter and exit the cabin. This coupling and uncoupling track comprises a set of transmission mechanisms that, in the event of a failure, can cause an emergency stop in the cable car's operation.Therefore, the state of the art reports documents related to emergency mechanisms in different systems such as patent document CN205533659U, and the internet pages called “VERSATILE PLATFORM FOR MOUNTING A VARIETY OF HARDWARE" retrieved from the link https: / / www.autom8.com / si skiyou- document “EXTRACTOR OF CRUCETAS DE.

[0007] TRANSMISSION” retrieved from the link https^ ws^w.partseurope.eu / es / producVu-joint- press-tool / 38,500446.

[0008] Document CN205533659U discloses an emergency bolt assembly for a head control device for oil well applications. The emergency bolt assembly includes a first bolt, a second bolt, and a connecting member, the first bolt and the second bolt being provided respectively at the two ends of the connecting member, and both the first bolt and the second bolt are connected to the flange when in use.

[0009] In addition, CN205533659U mentions a recessed section on the bottom surface of the connecting member. The recessed section is provided along the longitudinal length of the connecting member. The first bolt and the second bolt are mounted parallel to each other in the center connector, so the insertion of the two bolts into the bolt holes of the flange can be completed in one go. After this, only the nut needs to be installed at the bottom. The top of the flange does not require the use of a non-rotating wrench, so a single person can complete the flange fastening work independently.

[0010] For its part, the information published in “VERSATILE PLATFORM FOR MOUNTING A VARIETY OF HARDWARE” describes a versatile platform for mounting hardware at different heights on an isolation table or platform. The document mentions spacers of different lengths that are selected to vertically adjust the distance between a base plate and a top plate. The spacers are screwed to the plates with screws. Furthermore, it is also mentioned that to adjust the height of the platform, the spacers are screwed together with set screws. Furthermore, the publication mentions that the top and base plates are fixed to the four columns of spacers with cylindrical head screws.

[0011] Regarding the publication "TRANSMISSION CROSSHEAD EXTRACTOR," it discloses a transmission crosshead extractor device. The document shows in its figures that the extractor has a lower plate and an upper plate connected to each other by a pair of screws. The upper plate has a threaded central hole in which a press plunger is arranged, which is connected to said threaded central hole by an upper end with a male thread. The lower plate has an enclosure with a cylindrical cavity that is arranged coaxially with the press plunger.

[0012] However, the aforementioned documents do not refer to emergency mechanisms that allow stabilizing a cable car system mechanism. Specifically, the prior art does not disclose devices that allow stabilization.

[0013] BRIEF DESCRIPTION

[0014] In cable car-type transportation systems, the cabins or chairs that seat passengers move with the cable and are secured to it by means of a clamp. In some cases, upon entering a station where passengers can board and disembark, the cabin enters a coupling and uncoupling track where the clamp separates from the cable and the cabin slows down so that users can enter and exit the cabin. This coupling and uncoupling track comprises a set of parts and mechanisms that ensure the transmission of motion to the cabins, but at speeds different from those of the cable.

[0015] One of the sets of parts and mechanisms found on the coupling and uncoupling track includes a stabilization structure consisting of a first profile located on a second profile. Connected between these profiles are a plurality of bearings, to which pulleys and wheels are attached, allowing movement to be transmitted to the clamp that holds the cabin so it can move within the station and allow users to board or disembark.

[0016] The aforementioned bearings house bearings through which a shaft passes, connecting to a pulley and a wheel. The pulley is part of the transmission system that takes the cable's motion and applies a gear ratio to it to reduce it and use it to slow down the car's movement at the station. The wheel transmits the slowed motion to the car's clamp to advance the car.

[0017] The bearing has a first end where a first support member is located, and a second end where a second support member is located. The bearing also has a coupling hole where bearings are arranged. Specifically, the first bearing is arranged at the first end of the bearing structure and in the coupling hole, and the second bearing is arranged at the second end and in the coupling hole of the bearing structure.

[0018] According to the above, a shaft that connects to the wheel and the pulley is inserted into the coupling hole and is connected to a first bearing and a second bearing, which allows that, when said shaft rotates, both the wheel and the pulley rotate simultaneously.

[0019] Furthermore, the first support piece is simultaneously connected to a first side of the first profile and the second profile, while the second support piece is connected to a second side of the first profile and the second profile. Said first support piece and second support piece are connected by a fastening element, which may be a screw passing through the first profile or the second profile.

[0020] In accordance with the foregoing, the present disclosure relates to an emergency support for bearings in overhead cableway transportation systems, comprising a first plate with a perimeter, an internal surface, and an external surface parallel to the internal surface, said first plate including two fixing elements arranged on the internal surface. Furthermore, the emergency support for bearings in overhead cableway transportation systems comprises a second plate with a perimeter including two holes configured to connect with the two fixing elements of the first plate; and a groove located on the perimeter of said second plate. The first and second plates of the emergency support stabilize a bearing with respect to a profile of the overhead cableway transportation system.

[0032] DETAILED DESCRIPTION

[0033] A transportation system refers to a coordinated set of components, infrastructure, vehicles, and technologies designed to move people or goods from one place to another. These systems are essential for connectivity and mobility in urban, regional, and global areas.

[0034] In cable car-type transportation systems, the cabins or chairs that seat passengers move with the cable and are secured to it by means of a clamp. In some cases, upon entering a station where passengers can board and disembark, the cabin enters a coupling and uncoupling track where the clamp separates from the cable and the cabin slows down so that users can enter and exit the cabin. This coupling and uncoupling track comprises a set of parts and mechanisms that ensure the transmission of motion to the cabins, but at speeds different from those of the cable.

[0035] One of the sets of parts and mechanisms found on the coupling and uncoupling track includes a stabilization structure consisting of a first profile located on a second profile. Connected between these profiles are a plurality of bearings, to which pulleys and wheels are attached, allowing movement to be transmitted to the clamp that holds the cabin so it can move within the station and allow users to board or disembark.

[0036] The clutch and release mechanisms are made up of different parts, such as:

[0037] - A rail on which the skates of the cable car system's clamps roll;

[0038] - a clutch release ramp (inbound side), a clutch release ramp (outbound side), which actuates a movable jaw of the calipers; wheel ramps with tires in contact, at a calibrated pressure, with the upper part of the vehicle calipers, in order to drag them from their clutch release to their engagement on the cable; stabilization profiles, which properly hold the calipers; cable support and deflection pulleys; and vehicle stabilization devices at the station entrance and exit.

[0039] Referring to FIG. 3A and FIG. 3B, when a cabin of a cable car system enters a station, the cabin moves along a structure (70) that includes one or more stabilizing profiles, for example, a first profile (71) located above a second profile (72). In the embodiment of FIG. 3A and FIG. 3B, a plurality of bearings are connected between said profiles, wherein said bearings are connected to wheels connected to pulleys, and the pulleys are connected to each other with belts, which allow movement of the wheels, and said wheels in turn, allow stabilizing the cabins that enter or leave the stations while allowing their movement within the station.

[0040] Particularly, in an example of the clutch and release path where the invention is applied, and referring to FIG. 3 A and FIG. 5, between said profiles (71 and 72) there is located a bearing corresponding to a bearing structure (60) comprising a first bearing (65) and a second bearing (66) through which passes a shaft (52) that is connected to a pulley (51) and a wheel (50), in accordance with the above.

[0041] Specifically, referring to FIG. 3A and FIG. 3B, the bearing structure (60) has a first end where a first support piece (61) is located and a second end where a second support piece (73) is located. In addition, the bearing structure (60) has a coupling hole (64) in which bearings are arranged. Particularly, at the first end of the bearing structure (60) and in the coupling hole (64), a first bearing (65) is arranged, and in turn, at the second end and in the coupling hole (64) of the bearing structure (60) a second bearing (66) is arranged.

[0042] According to the above, in an example of the clutch and release path where the invention is applied, a shaft (52) that is connected to the wheel (50) and the pulley (51), is inserted into the coupling hole (64) and is inserted into the first bearing (65) and the second bearing (66), which allows that, when said shaft (52) rotates, both the wheel (50) and the pulley (51) rotate simultaneously.

[0043] Furthermore, the first support piece (61) is simultaneously connected to a first side of the first profile (71) and the second profile (72), while the second support piece (73) is connected to a second side of the first profile (71) and to a second side of the second profile (72). Said first support piece (61) and second support piece (73) are connected by a fixing element that can be a screw (67). In one embodiment of the present disclosure, and referring to FIG. 3 A and FIG. 3B, the first support piece (61) is located adjacent to the pulley (51). For its part, the second support piece (73) is located adjacent to the wheel (50).

[0044] In accordance with the foregoing, the present disclosure relates to an emergency support (10) for bearings in overhead cableway transportation systems, comprising: a first plate (20) with a perimeter, an internal surface (21) and an external surface (22) parallel to the internal surface (21), including: two fixing elements (24) arranged on the internal surface (21). Said emergency support (10) also comprises a second plate (40) with a perimeter, which includes two holes (42) configured to connect with the two fixing elements (24) of the first plate (20); and a slot (41) located on the perimeter of said second plate (40). Wherein the first plate (20) and the second plate (40) of the emergency support (10) stabilize a bearing with respect to a profile of the overhead cableway transportation system.

[0045] When the first bearing (65), the second bearing (66), or the pillow block structure (60) suffers some damage, the axle (52) becomes destabilized or changes orientation, destabilizing the wheel (50) and the pulley (51), which can cause a cabin that is moving within a station where said axle (52) is not correctly oriented, to become destabilized or the entire traction system to stop. Therefore, referring to FIG. 2A, FIG. 2B, FIG. 3 A and FIG. 3B in an example of the clutch and disengagement path where the invention is applied, the inner surface (21) of the first plate (20) and the inner surface (43) of the second plate (40) are connected between the first support piece (61) and the second support piece (73) of the pillow block structure (60).

[0046] In another example of the clutch and release path where the invention is applied, referring to FIG. 1 A, FIG. IB, and FIG. 6, a protuberance or projection of the bearing structure (60) or a portion of a screw (67) corresponding to the fixing element that allows the bearing structure (60) to be connected to the profiles is inserted into the groove (45, 46) of the second plate (40). Said first plate (20) and second plate (40) generate a force between them, adjusting the position of the bearing structure (60) and therefore correcting the orientation of the shaft (52).

[0047] Referring to FIG. IB, the first plate (20) is connected to the second plate (40) by the two fixing elements (24) arranged on the inner surface (21) of the first plate (20) which connect with the two holes (42) of the second plate (40).

[0048] For the understanding of the present disclosure it will be understood that the axis (52) of the bearing (60) is destabilized or changes orientation, and that the axis (52) is oriented in a correct way so that both the wheel (50) and the pulley (51) rotate, allowing the movement and stability of a cabin of a cable car system within a station. For example, if the axis (52) is correctly arranged in a horizontal position and perpendicular to the direction of movement of the cabin on the clutch and disengagement track, the fact that said axis (52) is destabilized or changes its orientation means that said axis (52) is no longer horizontal and perpendicular to the direction of movement of the cabin on the clutch and disengagement track.

[0049] In a first embodiment of the present disclosure, and in an example of the clutch and release path where said disclosure is applied, referring to FIG. 1 A and FIG. IB and FIG. 6 the first plate (20) is an element with a flat surface, and can be made of rigid material. Said first plate (20) can be oblong, that is, longer than it is wide and have two opposite longitudinal ends where the two fixing elements (24) are arranged, respectively. This allows that between the two fixing elements (24) and the internal surface (21) of the first plate (20) there is the appropriate length to embrace a profile of the clutch and release path.

[0050] Furthermore, in said first embodiment and referring to FIG. 1A , the inner surface (21) of the first plate (20) may have a protuberance (26) that engages the profile of the aerial cableway transportation system. For the purposes of the present disclosure, a protuberance is a bump or elevation on a surface. Said protuberance (26) prevents the disclosed emergency support from shifting or sliding from its position.

[0051] Said protuberance (26) may have an oblong shape, where the length of said protuberance (26) is given between the two fixing elements (24), and furthermore, it may have a rectangular prism shape.

[0052] For its part, and in said first embodiment and referring to FIG. IB the second plate (40) has an internal surface (43) and an external surface (44), and has two grooves, a first groove (45) and a second groove (46), wherein said grooves are contiguous with each other. Both the first groove (45) and the second groove (46) are located between the internal surface (43) and the perimeter of said second plate (40); wherein two projections of the bearing structure (60) are inserted into said grooves (45, 46) respectively, as seen in FIG. 6.

[0053] The above allows the second plate (40) to be coupled to the external shape of the bearing structure (60) and that by means of said coupling the position of said bearing structure (60) can be adjusted and, therefore, the orientation of the shaft (52).

[0054] Furthermore, and referring to FIG. IB, the second plate (40) may have a third groove (47) located between the inner surface (43) and the perimeter of said second plate (40), wherein said third groove (47) is located opposite to the first groove (45) and second groove (46) adjacent to each other. The above allows the second plate (40) to be coupled to the external shape of the bearing structure (60) when it has three projections or protuberances on its surface, which allows the grooves (45, 46, 47) to be coupled in a solidary manner with the protuberances or projecting elements of the bearing structure (60), and the position of said bearing structure (60) and, therefore, the orientation of the shaft (52) can be adjusted.

[0055] In a second embodiment of the present disclosure, and in another example of the clutch and release path where said disclosure is applied, referring to FIG. 3A , and FIG. 5 , the bearing (60) is held between the first profile (71) and the second profile (72) by means of two screws (67) that pass through and connect the first support piece (61) and the second support piece (73). In said embodiment, one of said screws (67) can fracture, causing the bearing structure (60) to become unstable and change the orientation of the shaft (52) or stop the entire transmission system. Therefore, in said embodiment, and referring to FIG. 2A and FIG.2B, the first plate (20) has an oblong central slot (25) extending from the perimeter and toward the center of said first plate (20); in said central slot (25) a portion of the screw (67) is inserted that connects the first support piece (61) and the first support piece (61) of the bearing structure (60).

[0056] In said second embodiment, a longitudinal end of the screws (67) protrudes from the first support piece (61), therefore, referring to FIG. 4A and FIG. 4B, the head of a screw (67) is inserted into the central slot (25) of the first plate (20), and furthermore, the internal surface (21) of said first plate (20) rests on the first support piece (61).

[0057] On the other hand, said second embodiment of the present disclosure, and referring to FIG. 2 A and FIG. 2B, the groove (41) of the second plate (40) has a convex arc-shaped contour with respect to the holes. In said embodiment, and referring to FIG. 3A, FIG. 3B, FIG. 4B and FIG. 4C, wherein the first support piece (61) is located adjacent to the pulley (51) and the second support piece (73) is located adjacent to the wheel (50), in this way the second support piece (73) is a flange that has an external contour with a circular shape, which allows the convex arc-shaped contour of the groove (41) of the second plate (40) to couple to the external surface of the second support piece (73).

[0058] Both the first plate (20) and the second plate (40) can have a shape that is selected from the group consisting of: squares, triangles, circles, rectangles, pentagons, trapezoids, ellipses, rhombuses, hexagons, heptagons, octagons, decagons, equivalent shapes known to a person moderately versed in the subject or a combination of the above.Furthermore, the material of the first plate (20) and the second plate (40) is selected from the group consisting of: carbon steel, iron castings, galvanized iron, chromium steels, chromium-nickel steels, chromium-nickel-titanium steels, nickel-chromium-molybdenum-tungsten alloy, chromium-molybdenum ferrous alloys, 301 stainless steel, 302 stainless steel, 304 stainless steel, 316 stainless steel, 405 stainless steel, 410 stainless steel, 430 stainless steel, 442 stainless steel, manganese alloy steel, equivalent materials known to a person of ordinary skill in the art, or a combination of the foregoing.

[0059] In any of the previously described embodiments of the present disclosure, and with reference to FIG. 1A, FIG. 1B, FIG. 2A and FIG. 2B, the two fixing elements (24) may be two screws parallel to each other, which are connected to the second plate (40). Particularly, said two fixing elements (24) may be parallel screws that can be fixedly or removably connected to the first plate (20) and can be inserted into the two holes (42) of the second plate (40). In addition, said fixing elements (24) may include slots for arranging padlock pins or another element that prevents the first plate (20) or the second plate (40) from sliding relative to them.

[0060] Furthermore, in any of the previously described embodiments of the present disclosure, and referring to FIG. 1 A, FIG. IB, FIG. 2A and FIG. 2B, the first plate (20) and the second plate (40) are arranged parallel to each other, which allows them to properly reorient the bearing structure (60).

[0061] On the other hand, and referring to FIG. 2 A and FIG. 2B, a guide bar (30) may protrude perpendicularly from the inner surface (21) of the first plate (20), and connects with the inner surface (43) of the second plate (40). Said guide bar (30) is configured so that the first plate (20) and the second plate (40) remain parallel to each other. That is, while the two fixing elements (24) may allow the first plate (20) and the second plate (40) to be in a parallel position, the guide bar (30) ensures that said plates remain parallel to each other. In addition, two guide bars (30) may be connected between the first plate (20) and the second plate (40).

[0062] Additionally, and referring to FIG. 2A and FIG. 2B, in another embodiment of the present disclosure the two holes (42) of the second plate (40) may be two female threaded elements, wherein each female threaded element is configured to connect with the two fixing elements (24) housed in the two perforations (23) of the first plate (20). This allows two fixing elements (24) to be threaded bars that are inserted into the female threaded elements, without the need to require nuts.

[0063] On the other hand, the two perforations (23) of the first plate (20) can also be two female threaded elements, where each female threaded element is configured to connect with the two fixing elements (24).

[0064] EXAMPLES

[0065] EXAMPLE 1

[0066] Referring to FIG. 1 A and FIG. IB, an emergency support (10) for bearings in overhead cableway systems was developed, comprising:

[0067] - a first plate (20) with a perimeter, an inner surface (21) and an outer surface (22) parallel to the inner surface (21), including two fixing elements (24) arranged on the inner surface (21). The inner surface (21) of the first plate (20) has a protuberance (26) that engages with the profile of the overhead cableway system;

[0068] - a second plate (40) with a perimeter, including two holes (42) configured to connect with the two fixing elements (24) of the first plate (20));

[0069] - the second plate (40) has an internal surface (43) and an external surface (44), and has a first groove (45) and a second groove (46) adjacent, located between the internal surface (43) and the perimeter of said second plate (40). In addition, said second plate (40) has a third groove (47) located between the internal surface (43) and the perimeter of said second plate (40);

[0070] - in said example, the first plate (20) and the second plate (40) have a surface that is parallel to each other, and are furthermore connected by two fixing elements (24) that are threaded bars. In addition, said first plate (20) has a thickness of 22.5 mm and said second plate (40) has a thickness of 32 mm.

[0071] Said emergency support (10) made it possible to secure the structure of a bearing (60) to the stabilizing profile of the clutch and release track, in case the screws (67) fracture or bend or if another failure causes the axis (52) of the bearing (60) to deviate, causing the wheel (50) and the pulley (51) to lose their parallelism with the direction of travel of the clutch and release track. In cable transport systems, the repair of this type of failure can represent a stoppage of approximately one hour. However, the use of the emergency support of the present invention allows a provisional repair that can take between 5 and 15 minutes. Which is a very important time difference if it is considered that there are users waiting for the resumption of service inside the stopped cabins.

[0072] EXAMPLE 2

[0073] Referring to FIG. 2A and FIG. 2B, an emergency support (10) for bearings in overhead cableway systems was developed, comprising:

[0074] - a first plate (20) with a perimeter, an inner surface (21) and an outer surface (22) parallel to the inner surface (21), including two fixing elements (24) arranged on the inner surface (21). The first plate (20) has an oblong central slot (25) extending from the perimeter and towards the center of said first plate (20);

[0075] - a second plate (40) with a perimeter, including two holes (42) configured to connect with the two fixing elements (24) of the first plate (20); and a groove (41) located on the perimeter of said second plate (40). The groove (41) of the second plate (40) has a convex arc-shaped contour with respect to the holes (42);

[0076] - in said example, the first plate (20) and the second plate (40) have a surface that is parallel to each other, and are furthermore connected by two fixing elements (24) that are threaded bars. In addition, said plates (20, 40) have a thickness of 9.5 mm.

[0077] Said emergency support (10) made it possible to secure the structure of a bearing (60) to the first and second stabilizing profiles of the clutch and release track, in case the screws (67) fracture or bend or if another fault causes the shaft (52) of the bearing (60) to deviate, causing the wheel (50) and the pulley (51) to lose their parallelism with the direction of travel of the clutch and release track. In cable transport systems, the repair of this type of faults can represent a stoppage of approximately one hour. However, the use of the emergency support of the present invention allows a provisional repair that can take between 5 and 15 minutes. Which is a very important time difference if one considers that there are users waiting for the resumption of service inside the stopped cabins.

[0078] It should be understood that the present invention is not limited to the described and illustrated modalities, since as will be evident to a person skilled in the art, there are possible variations and modifications that do not depart from the spirit of the invention, which is only defined by the following claims.
