Description

Technical Field

[0001] This invention belongs to the field of cableway rescue technology and relates to a GPS-based cableway entrapment rescue device. Background Technology

[0002] Cableways are widely used for long-distance passenger transport in outdoor environments. However, malfunctions can also frequently lead to people getting trapped in cableways.

[0003] Current cableway rescue operations mainly rely on rescuers locating the trapped individuals. Rescuers need to arrive at the scene with rescue equipment based on the location, and then use a series of lifting mechanisms to lift the rescuers and equipment to the trapped individuals' location for rescue. This rescue method is time-consuming due to the large amount of equipment involved and the high operational requirements, resulting in low rescue efficiency. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a GPS-based cableway entrapment rescue device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A GPS-based cableway entrapment rescue device includes a cableway mechanism, a boom, and a descent device. The cableway mechanism includes a pulley that abuts against a steel wire rope, a drive structure for driving the pulley to rotate, and a braking structure for braking the pulley. The braking structure includes friction pads, which abut against the pulley when braking. The boom is connected to the cableway mechanism, and the descent device is connected to the boom. The descent device includes a pull rope, which is connected end-to-end in a loop. The device also includes a GPS positioning device for determining the location of the rescue device.

[0007] Furthermore, the braking structure includes an upper bracket and a lower bracket located on the upper and lower sides of the wire rope, respectively, and the pulleys are provided on both the upper bracket and the lower bracket; it also includes a telescopic structure, which is connected to the upper bracket and the lower bracket at both ends in the telescopic direction.

[0008] Furthermore, the braking structure also includes a connecting rod, the friction pad is fixed on the connecting rod, and a spring, one end of which is connected to the connecting rod and the other end is connected to the upper bracket or the lower bracket. The extension and retraction direction of the spring is parallel to the extension and retraction direction of the extension and retraction structure.

[0009] Furthermore, the upper support is provided with two pulleys, and the lower support is provided with at least one pulley, which is located between the two pulleys of the upper support.

[0010] Furthermore, the driving structure includes a first motor fixedly mounted on the upper bracket or the lower bracket, the first motor driving at least one of the pulleys to rotate.

[0011] Furthermore, the descent device includes a housing, inside which a deceleration structure is provided, the pull rope is sleeved on the deceleration structure, and the pull rope is provided with a sling.

[0012] Furthermore, it also includes a winding device located outside the housing. The winding device includes a base and two straight rods disposed on the base. The number of straight rods is two and they are arranged in parallel. The pull rope passes between the two straight rods, and the straight rods are perpendicular to the pull rope. It also includes a second motor for driving the base to rotate. The rotation axis of the base is parallel to the straight rods and located between the two straight rods.

[0013] Furthermore, there are two descent devices, which are respectively located on the left and right sides below the boom.

[0014] In summary, the advantages of this invention are:

[0015] 1) The rescue equipment of the present invention is transported directly via cableway. It can be transported by its own drive structure or by auxiliary steel cable, without the need for rescue personnel to carry it, which greatly reduces the load on rescue personnel and shortens the time to reach the scene. In addition, the rescue equipment is equipped with GPS positioning, which can accurately locate the trapped location along the cableway, quickly transport it to the scene and provide positioning.

[0016] 2) The rescue equipment is equipped with a drive structure and a braking structure, which can move and stop at will on the cableway, providing high stability and good safety in rescue operations.

[0017] 3) The rescue equipment is directly installed on the cableway, and a descent device is provided for rescuers to operate. Rescuers do not need to bring the rescue equipment onto the cableway, which greatly improves the convenience of operation.

[0018] 4) The pull rope of the descent device in the rescue equipment is looped and equipped with a retractor, which can realize the rapid release and retraction of the pull rope, thereby enabling more efficient rescue of multiple trapped people, greatly reducing rescue time and improving rescue efficiency.

[0027] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0028] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be changed arbitrarily, and the layout of the components may also be more complex.

[0029] In this embodiment of the invention, all directional indicators (such as up, down, left, right, front, back, lateral, longitudinal, etc.) are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0030] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of the present invention may actually be an approximate parallel relationship, and the perpendicular relationship may actually be an approximate perpendicular relationship.

[0031] like Figure 1 As shown, a GPS-based cableway entrapment rescue device includes a cableway mechanism, a boom 2, a descent device, and a GPS positioning device. The cableway mechanism is mounted on the steel wire rope 1 of the cableway and is equipped with a drive structure and a braking structure to move and stop along the steel wire rope 1. The boom 2 connects the descent device to the cableway mechanism. The GPS positioning device can accurately locate the position of the rescue device in real time, allowing the rescue device to move along the steel wire rope 1 to the rescue location under the drive of the cableway mechanism. After the rescue device reaches the rescue location, the descent device can provide a safe high-altitude descent function for the trapped person, eliminating the need for rescuers to carry additional descent equipment for high-altitude operations.

[0032] Furthermore, the steel wire rope 1 erected by the zipline mechanism may not be the main cable of the cableway, but may be an auxiliary cable. The auxiliary cable has an independent driving mechanism for operation, so the operation of the zipline mechanism does not depend on the movement of the main cable. Thus, if the main cable fails, the zipline mechanism can still be moved to the rescue position through the auxiliary cable.

[0033] The zipline mechanism includes an upper support 12, a lower support 11, a drive mechanism, and a braking mechanism. The upper support 12 and the lower support 11 are located on the upper and lower sides of the wire rope 1, respectively. Both the upper support 12 and the lower support 11 are provided with pulleys 13. The circumference of the pulleys 13 abuts against the wire rope 1. The pulleys 13 are rotatable so that the zipline mechanism can travel on the wire rope 1.

[0034] The driving mechanism includes a first motor, which is fixedly mounted on the upper bracket 12 or the lower bracket 11. The first motor is used to drive the pulley 13 on the upper bracket 12 to rotate or drive the pulley 13 on the lower bracket 11 to rotate. The driving method includes, but is not limited to, belt and pulley drive or chain and sprocket drive.

[0035] The braking mechanism includes a telescopic structure, a connecting rod 14, and a friction plate 15, as shown in the reference. Figure 2 , 3The telescopic structure includes a main rod 111 and a secondary rod 121 sleeved within the main rod 111. The outer wall of the secondary rod 121 is clearance-fitted with the inner wall of the main rod 111, and the secondary rod 121 telescopically extends and retracts relative to the main rod 111 in the vertical direction. The lower support 11 is fixedly connected to the main rod 111, and the upper support 12 is fixedly connected to the secondary rod 121. Thus, the telescopic movement of the secondary rod 121 will cause the upper support 12 and the lower support 11 to move closer to each other or further away. The driving method for the telescopic movement of the secondary rod 121 and the main rod 111 includes, but is not limited to, cylinders, hydraulic cylinders, etc. Alternatively, a lead screw can be installed inside the main rod 111, and the lead screw is threadedly connected to the secondary rod 121. The telescopic movement is achieved by driving the lead screw to rotate, thereby driving the linear movement of the secondary rod 121.

[0036] The connecting rod 14 and the friction plate 15 are disposed between the upper support 12 and the lower support 11. When the upper support 12 and the lower support 11 approach each other, the pulley 13 first applies a greater force to the wire rope 1, and the staggered upper and lower pulleys 13 cause the wire rope 1 to bend to a certain extent, so that the contact area between the wire rope 1 and the pulley 13 is larger and the contact is tighter. Secondly, the connecting rod 14 drives the friction plate 15 to abut against the circumferential surface of the pulley 13, thereby generating a large friction force between the friction plate 15 and the pulley 13, making the pulley 13 unable to rotate. This fixes and limits the cable mechanism and the wire rope 1 to a certain extent, so that the cable mechanism will not move on the wire rope 1 under a certain range of force, achieving the effect of braking and stopping.

[0037] In order to achieve close contact with the wire rope 1, the pulleys 13 are arranged on the upper support 12 in this embodiment. This is to form two points on the left and right sides to support the wire rope 1, which provides good stability. The pulleys 13 arranged on the lower support 11 are at least one, preferably two.

[0038] In one embodiment, reference Figure 4 As shown, the lower support 11 has one pulley 13, which is horizontally positioned between the two pulleys 13 on the upper support 12. The line connecting the centers of the three pulleys 13 forms an inverted triangle. The connecting rod 14 is positioned between the upper support 12 and the lower support 11. There are three friction plates 15, which are respectively positioned at the left and right ends and the lower side of the middle of the connecting rod 14. The three friction plates 15 are used to abut against the three pulleys 13. A spring 16 is also provided, which extends and retracts vertically. One end of the spring 16 is connected to the connecting rod 14, and the other end is connected to the upper support 12.

[0039] When the telescopic mechanism drives the upper support 12 and the lower support 11 to move closer to each other, the friction plate 15 located in the middle of the connecting rod 14 first abuts against the circumferential surface of the pulley 13 of the lower support 11, and then pushes the connecting rod 14 to squeeze the spring 16. The friction plates 15 at both ends of the connecting rod 14 abut against the two pulleys 13 of the upper support 12 respectively, thereby braking the three pulleys 13, so that the cable mechanism can brake and stop on the wire rope 1.

[0040] In another embodiment, refer to Figure 2 As shown, the lower support 11 has two pulleys 13, which are arranged horizontally between the two pulleys 13 of the upper support 12. The line connecting the centers of the four pulleys 13 forms an inverted trapezoid, forming four fulcrums that contact the wire rope 1, resulting in better stability. There are two connecting rods 14, which are respectively arranged above and below the wire rope 1. There are four friction plates 15, which are respectively arranged at the left and right ends of the two connecting rods 14. The middle of the two connecting rods 14 forms a corresponding abutment. The upper and lower connecting rods 14 are each provided with the spring 16 described in the previous embodiment, which is used to connect with the upper support 12 and the lower support 11 respectively.

[0041] Furthermore, when the telescopic mechanism drives the upper support 12 and the lower support 11 to approach each other, the abutting parts on the two connecting rods 14 abut against each other, thereby driving the two connecting rods 14 to approach the upper and lower supports respectively and compress the two springs 16. A gap is formed in the middle of the two abutting parts for the steel wire rope 1 to pass through, avoiding compression of the steel wire rope 1. The movement of the two connecting rods 14 drives the four friction plates 15 to abut against the circumferential surfaces of the four pulleys 13 respectively, thereby braking the four pulleys 13, so that the cable mechanism can brake and stop on the steel wire rope 1.

[0042] The boom 2 is located below the zipline mechanism. The upper end of the boom 2 is connected to the lower end of the main rod 111. The lower side of the boom 2 extends to the left and right to form two ends. Each end is equipped with a descent device. Thus, the rescue device in this embodiment can achieve simultaneous rescue of two people.

[0043] The descent device in this embodiment includes a housing 3 and a pull rope 31. The pull rope 31 passes through and exits the housing 3. A deceleration structure is provided inside the housing 3 to decelerate the pull rope 31. The deceleration structure inside the housing 3 adopts the structure of mainstream descent devices in the prior art, so it will not be described in detail here. In the existing mainstream descent devices, one end of the pull rope 31 is wound on a rope reel, and the other end is connected to a sling. During use, the sling is tied to the person being rescued. During the descent, the pull rope 31 is continuously pulled out of the rope reel. After each rescue, the pull rope 31 needs to be rewound back to the rope reel. The winding of the rope reel is very cumbersome and difficult to operate in complex environments. Therefore, the existing descent devices are inefficient in the rescue of multiple people.

[0044] Unlike existing mainstream descent devices, the pull rope 31 in this embodiment is configured as a loop with the ends connected, and a winding device is provided on the lower side of the housing 3, as shown in the reference. Figure 5 The winding device includes a base 32, on which two parallel straight rods 33 are provided. The base 32 can rotate under the drive of a second motor 34, and the central axis of rotation is parallel to the straight rods 33 and located between the two straight rods 33, preferably at the center point of the line connecting the centers of the two straight rods 33. The straight rods 33 are transverse and perpendicular to the hanging direction of the pull rope 31.

[0045] With the pull rope 31 fully suspended, the sling is positioned at the lower end of the pull rope 31. One of the left and right sections of the pull rope 31 passes between the two straight rods 33, as shown in the reference. Figure 6 Therefore, when the winding device rotates, the two straight rods 33 can wind the pull rope 31, and simultaneously wind the pull rope 31 above and below the winding device, as shown in the figure. Figure 7 The winding speed is doubled, which can quickly lift the sling to the top for the next trapped person to use. This effectively improves the efficiency of the descent device in the continuous rescue of multiple trapped persons.

[0046] It should be added that when the trapped person is descending while wearing the harness, the rope 31 can be released simply by reversing the reel, making the structure simple and easy to use.

[0047] To ensure the winding effect of the rewinder and prevent the pull rope 31 from slipping, the outer peripheral wall of the straight rod 33 is provided with ribs to increase the friction on the pull rope 31.

[0048] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
