DETAILED DESCRIPTION

[0031] The following will be combined with the attached Figures 1 to 11 The technical solution of the present invention is further described.

[0032] The described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] Embodiment 1: like Figures 1 to 4 As shown, a cable hoisting device includes at least two groups of cables 100, and both ends of the cables 100 are anchored at anchor points. Hydropower stations are mostly built in canyons. When used, the anchor points at both ends of the cables 100 are set on the mountains at both ends of the dam or on the poured concrete piers in combination with the terrain. The cable crane adopts a fixed non-walking mobile setting, which reduces the construction and operation costs of the original steel structure cable crane tower operation platform, foundation and track, auxiliary facilities, etc. Although such a setting cable crane cannot be moved, it seems to reduce the scope of the working area, but the problem of insufficient working area can be compensated by the innovative design of the structure. The use of fixed anchor points and the appropriate increase in the verticality of the cable crane can greatly reduce the internal stress of the cable, and can effectively increase the bearing capacity of the cable crane, make full use of the strength of the cable, and avoid the problem of significant load reduction caused by the mobile cable crane load.

[0037] At least one cable car 200 is arranged on two adjacent groups of cables 100, that is, one cable car 200 is supported by two cables 100. However, a plurality of cable car trolleys 200 may be arranged on a pair of cables according to the carrying capacity, such as Figure 3 shown.

[0038] The cable car 200 includes a trolley platform 210, at least two sets of running mechanisms 220 are provided at the bottom of the trolley platform 210, the running mechanisms 220 move along the cable 100, the running mechanisms 220 include a running bracket 221, the running bracket 221 is provided with a first running wheel 222 and a first supporting wheel 223 driven by a motor, the cable 100 is arranged between the first running wheel 222 and the first supporting wheel 223, and a lifting mechanism 300 is provided on the trolley platform 210. The first supporting wheel 223 does not have a driving device, and the function of the first supporting wheel 223 is to avoid the risk of overloading or overturning of the cable car 200 when the lifting mechanism 300 is overloaded.

[0039] Preferably, Figure 1 As shown, two sets of traveling mechanisms 220 are arranged at the bottom of the trolley platform 210 relative to each set of cables 100, and the traveling brackets 221 of each set of traveling mechanisms 220 are hinged to the trolley platform 210. This structural setting enables the cable car trolley 200 to adapt to the curvature of the cable 100 at different positions, and the trolley platform 210 and the traveling mechanism 220 form different angles, so that the trolley platform 210 can run smoothly and reliably at different curvature positions of the cable.

[0040] In this embodiment, if Figure 2 and 4As shown, the lifting mechanism 300 includes at least one group of mobile trolleys 310 arranged on the trolley platform 210. In this embodiment, two groups of mobile trolleys 310 are arranged symmetrically at the left and right ends. A guide rail 211 is arranged on the upper side of the trolley platform 210, and the guide rail 211 is symmetrically arranged along the hanging hole 212. The bottom of the body of the mobile trolley 310 is provided with a second running wheel 311 driven by a motor that cooperates with the guide rail 211. The mobile trolley 310 is provided with a winch 320, and the lifting rope of the winch 320 is connected to the main hook mechanism 330. The trolley platform 210 is provided with a hanging hole 212 for the main hook mechanism 330 to pass through, and the hanging hole 212 is a strip hole parallel to the guide rail 211.

[0041] The moving trolley 310 moves along the guide rail 211 to drive the main hook mechanism 330 to adjust the lifting position.

[0042] Preferably, Figure 4 As shown, a lifting arm 340 is provided at the end of the mobile trolley 310, and an arm wheel 350 cooperating with the guide rail 211 is provided at the bottom of the lifting arm 340. The lifting arm 340 can move synchronously with the mobile trolley 310 to meet the needs of expanding the working area outside the track.

[0043] A second supporting wheel 360 is provided on the upper side of the lifting arm 340, and a plurality of supporting rollers 380 are provided on the lower side. An end hook mechanism 370 is provided at the end of the lifting arm 340. The end hook mechanism 370 includes an end wheel 371 provided at the end of the lifting arm 340, a first movable pulley 372 is provided below the end wheel 371, and a side hook 373 is provided on the wheel frame of the first movable pulley 372. The main hook mechanism 330 includes a steering wheel 331 provided at the bottom of the moving trolley 310, a second movable pulley 332 is provided below the steering wheel 331, and a main hook 333 is provided on the wheel frame of the second movable pulley 332. The lifting rope of the winch 320 passes through the upper side of the second supporting wheel 360, bypasses the end wheel 371 and the first movable pulley 372 in sequence, bypasses the supporting roller 380 and the upper side of the steering wheel 331 in sequence, and finally bypasses the second movable pulley 332 and is fixed to the bottom of the moving trolley 310.

[0044] A first upper electromagnet 375 is provided on the wheel frame of the end wheel 371 through a mounting frame 374, a first lower electromagnet 376 is provided on the wheel frame of the first movable pulley 372 corresponding to the first upper electromagnet 375, a second upper electromagnet 335 is installed on the wheel frame of the steering wheel 331 through a supporting frame 334, and a second lower electromagnet 336 is provided on the wheel frame of the second movable pulley 332 corresponding to the second upper electromagnet 335.

[0045] The main hook mechanism 330 and the end hook mechanism 370 can work in time sharing. The winch 320 first retracts the lifting rope. In the initial state, the first upper electromagnet 375 and the first lower electromagnet 376 are powered on for adsorption, and the second upper electromagnet 335 and the second lower electromagnet 336 are powered on for adsorption. When it is necessary to operate the main hook mechanism 330, the first upper electromagnet 375 and the first lower electromagnet 376 remain in the powered on adsorption state, and the second upper electromagnet 335 and the second lower electromagnet 336 are powered off to release the adsorption, and the winch 320 controls the main hook 333 to move up and down for lifting operations. When it is necessary to operate the end hook mechanism 370, the second upper electromagnet 335 and the second lower electromagnet 336 remain in the adsorption state, and the first upper electromagnet 375 and the first lower electromagnet 376 are powered off to release the adsorption, and the winch 320 controls the side hook 373 to move up and down for lifting operations.

[0046] During the hoisting process, the cable car 200 moves back and forth on the cable 100, and the mobile car 310 moves left and right with the lifting arm 340, which can achieve a full-range hoisting operation with a larger coverage than a pair of cables 100, achieving a good operating effect.

[0047] Preferably, the end of the guide rail 211 is provided with a limit protrusion 213 and an electronic limit switch 214. In order to ensure that the mobile trolley 310 does not derail and runs safely through multiple protections.

[0048] During specific use, a position sensor 230 is provided on the trolley platform 210 or the walking mechanism 220. The position of the trolley can be accurately located in real time. When multiple cable car trolleys 200 are running on the same cable, the positioning and program control of the position sensors of each cable car trolley 200 can ensure that the cable car trolleys 200 maintain a suitable spacing distance to avoid the risk of collision. When the distance is too close, the cable car trolley 200 stops running in time or evades in a farther direction. A lightning arrester 240 is also provided on the cable car trolley 200 to ensure that lightning protection measures are reliable in thunderstorms. The cable car trolleys 200 can not only share a pair of cables 100, but also only share one cable 100. This arrangement is more flexible and more adaptable. Figure 3 shown.

[0049] Preferably, Figure 1As shown, a maintenance mechanism 500 is provided below at least one end of the cable 100, and the maintenance mechanism 500 includes maintenance platforms 510 respectively arranged on both sides of the cable 100, and the maintenance platforms 510 are supported and connected to the rock wall through maintenance brackets 520. Two maintenance platforms 510 form a group, that is, a maintenance platform 510 is respectively provided below the left and right ends of each cable 100. This arrangement is for when the cable car 200 travels to a position where the end of the cable 100 is flush with the maintenance platform 510, the main hook mechanism 330 is arranged between the two groups of maintenance platforms 510, and does not interfere with the maintenance platform 510. The maintenance platform can be used for installation or maintenance of the device of the present invention.

[0050] As a preferred embodiment of the present invention, Figure 4 and 5 As shown, it also includes a power supply control mechanism 400, which includes an electric control cabinet 410 arranged on the cable car 200 or the mobile car 310, a power supply board 420 is laid along the cable 100, and a power supply board 420 is arranged at a position on the side of the cable 100 that does not affect the operation of the first walking wheel 222 and the first supporting wheel 223. The power supply board is arranged along the length of the cable 110, and the end of the power supply board 420 is externally connected to a power supply. The walking bracket 221 is connected to a contact plate 440 through a spring 430. The contact plate 440 is arranged close to the power supply board 420 under the action of the spring 430 to ensure reliable power supply. The contact plate 440 is electrically connected to the electric control cabinet 410 through a cable 450 to supply power to the electric control cabinet 410. The power is transmitted from the power supply board 420 to the contact plate 440 and then transmitted to the electric control cabinet 410 through the cable 450 to be distributed to various devices for use.

[0051] An insulating pad 460 is disposed between the power supply board 420 and the cable 100 to insulate the power supply board 420 from the cable 100 .

[0052] The device of the present invention is controlled by wireless control, and the device is controlled through an operation room set at a suitable position on the ground. Semi-automatic or fully automatic control can also be achieved through built-in programs and responsive sensors in the control system.

[0053] Embodiment 2: Different from Example 1, Figures 6 to 11 As shown, at least one of the two adjacent groups of cables 100 has an adjustable cable point 120 at its end, and a fixed cable point 130 at the other end. By setting the adjustable cable point 120, when the cables 100 have been used for a period of time and have different elongations, adjustments can be made conveniently to adjust the verticality of the cables 100 to be consistent, thereby ensuring that the cable trolley is in good operating condition.

[0054] It is preferred to set an adjustable cable point 120 at one end of one of the two cables 100 arranged in a pair. When the two cables 100 have different elongations after being subjected to force, it is sufficient to adjust the length of the adjustable cable to be consistent with the length of the non-adjustable cable. In this way, the structure of the adjustment mechanism is simplified while satisfying the adjustment function.

[0055] Casting cable heads 110 with inverted cone structures are provided at both ends of the cable 100, and locking mechanisms 700 for locking the cable heads 110 are provided in the platforms 600 corresponding to the two ends of the cable 100, a trough box 610 is provided in the platform 600 corresponding to the fixed cable point 130, and a corridor 620 is provided in the platform 600 corresponding to the adjustable cable point 120, and cover plates 690 are provided on the tops of the trough box 610 and the corridor 620, and the locking mechanisms 700 are arranged in the trough box 610 and the corridor 620.

[0056] The locking mechanism 700 corresponding to the fixed cable point 130 includes two groups of semi-annular pull plates 710 clamped on the outside of the cable head 110, and flange plates 720 are provided on the outside of the opening positions of the two groups of semi-annular pull plates 710. The flange plates 720 of the two groups of semi-annular pull plates 710 are connected by flange bolts. The flange plates 720 are provided with through holes that cooperate with the side clamping shafts 730. The cable head 110 is initially locked by inserting the side clamping shafts 730 into the through holes of the flange plates 720 and the locking holes 630 on the top of the cover plate 690 at the same time.

[0057] A pull ring 740 is provided at one end of the semi-annular pull plate 710 close to the cable head 110, and a limit ring 760 is provided inside the pull ring 740 to cooperate with the main clamping shaft 750. A locking hole 630 is provided on the top of the cover plate 690 to cooperate with the side clamping shaft 730 and the main clamping shaft 750.
