The rope supporting device speed adjusting device 1 comprises a traction pulley block 13 and a driving pulley block 120, the traction pulley block 13 corresponds to the first rope supporting traction rope 102, the first rope supporting traction rope 102 bypasses the reversing pulley block 5 and then matches with the corresponding traction pulley block 13, the driving pulley block 120 can drive all the traction pulley block 13 to rotate, at least two of the first rope supporting traction rope 102 are different in speed and all the mid-span rope supporting devices 4 are located between the reversing pulley block 5 and the rope supporting device speed adjusting device 1, one end of the rope supporting driving traction rope 101 is connected with the sports car system 6, the other end of the rope supporting driving traction rope 101 sequentially bypasses the driving pulley block 120 and the reversing pulley block 5 and then is connected with the sports car system 6.

When the supporting cable system is applied to a cable crane, cable towers 9 are arranged at two ends of the cable crane, and two ends of a bearing cable 10 penetrate through the cable towers 9 and are anchored on the ground, so that a running track is provided for a sports car system 6 and a mid-span supporting cable device 4. The traction cables 104 and the hoisting cables 107 of the sports cars mainly turn through the cable saddle wheel set 25 and stretch and retract through the corresponding windlasses 90, so that the sports cars run along the bridge direction through the traction cables 104 of the sports cars, and the hoisting cables 107 realize vertical movement of hoisted objects.

In operation, the sports car traction rope 104 drives the sports car system 6 to move along the bridge direction on the bearing rope 10, because one end of the supporting rope driving traction rope 101 is connected with the sports car system 6, the other end of the supporting rope driving traction rope 101 sequentially bypasses the driving pulley block 120 and the reversing pulley block 5 and then is connected with the sports car system 6, the sports car system 6 drives the supporting rope driving traction rope 101 to move, the supporting rope driving traction rope 101 drives the driving pulley block 120 to move, then the driving pulley block 120 drives all the traction pulley blocks 13 to rotate, the traction pulley blocks 13 drive the corresponding first supporting rope 102 to move, so that at least two first supporting rope 102 speeds are different, because the first supporting rope 102 and the second supporting rope 103 are respectively connected between the corresponding mid-span cable devices 4 at two sides of the sports car system 6, the first supporting rope 102 and the second supporting rope 103 enclose a closed loop, the different speeds correspond to positions of the different mid-span cable devices 4, so as to provide the corresponding operating speeds for each mid-span cable device 4, and achieve better control of the mid-span cable devices 4, thereby achieving better control effect of controlling the moving of the mid-span devices 4.

As shown in fig. 3 to 7, the rope supporter speed adjusting device 1 described in this embodiment specifically includes a driving pulley block 120, a driving shaft 15, and at least two traction pulley blocks 13, wherein:

one end of a supporting rope driving traction rope 101 is connected with a sports car system 6, the other end of the supporting rope driving traction rope 101 sequentially bypasses a driving pulley block 120 and a reversing pulley block 5 and then is connected with the sports car system 6, so that when the sports car system 6 walks on a bearing rope 10 in a reciprocating manner, the supporting rope driving traction rope 101 can drive the driving pulley block 120 to rotate in a reciprocating manner, the driving pulley block 120 drives a driving shaft 15 to rotate in a moving manner, the driving pulley block 13 comprises a speed regulating wheel 11, a first wheel groove 19 matched with a corresponding first supporting rope traction rope 102 is formed in the speed regulating wheel 11, the speed regulating wheel 11 is in driving fit with the driving shaft 15 through a transmission mechanism 14, the driving shaft 15 can drive the speed regulating wheels 11 in at least two traction pulley blocks 13 to rotate, and the linear speeds of the first wheel grooves 19 in at least two speed regulating wheels 11 are different, so as to achieve the purpose that the speeds of at least two first supporting rope traction ropes 102 are different; the purpose of synchronous speed regulation of at least two speed regulation wheels 11 is further achieved, the speed regulation wheels 11 and the first supporting rope 102 are correspondingly arranged, the single first supporting rope 102 bypasses the speed regulation wheels 11, the first supporting rope 102 is driven to move through rotation of the speed regulation wheels 11, linear speeds of the first wheel grooves 19 on at least two speed regulation wheels 11 are different, the requirements of different moving speeds of different first supporting rope 102 are met, and therefore the purpose of adapting to different walking speeds of the mid-span supporting rope device 4 is achieved.

The number of the mid-span guy apparatus 4 is even, the number of the mid-span guy apparatus 4 at two sides of the sports car system 6 is the same, when the number of the mid-span guy apparatus 4 is at least four, the moving speed of the mid-span guy apparatus 4 close to the sports car system 6 on the bearing rope 10 in the adjacent mid-span guy apparatus 4 at one side of the sports car system 6 is greater than the moving speed of the mid-span guy apparatus 4 far away from the sports car system 6 on the bearing rope 10.

Since the first rope 102 will limit the minimum diameter of the flywheel 11 when the first rope 102 is engaged with the flywheel 11, when the flywheel 11 is designed, the diameter of the flywheel 11 is greater than the minimum diameter of the flywheel 11, under this condition, when the number of the flywheel 11 is at least 3, if the purpose of different linear velocities of the first wheel grooves 19 on the different flywheels 11 is achieved based on setting different diameters of the different flywheels 11, the diameters of the other flywheels 11 will be gradually increased based on the flywheel 11 with the minimum diameter, which will cause the diameter of the flywheel 11 with the maximum linear velocity of the first wheel groove 19 to be very large, and further cause the base for installing the flywheel 11 to be very large, thereby greatly increasing the structural cost of the rope supporter speed adjusting device 1. Meanwhile, the flywheel 11 with different diameters can cause the respective service lives of the different first supporting rope traction ropes 102 matched with the flywheel to be significantly different, so that the maintenance and replacement times of the first supporting rope traction ropes 102 can be increased, and the maintenance cost can be increased. Therefore, in the rope supporting device speed adjusting device 1 of the present embodiment, all the diameter of the speed adjusting wheels 11 are the same, and the purpose that the linear velocities of the first wheel grooves 19 on at least two speed adjusting wheels 11 are different is achieved by utilizing different rotation angular velocities of the speed adjusting wheels 11, and at the same time, only the diameter of the speed adjusting wheel 11 is larger than the minimum diameter of the speed adjusting wheel 11, compared with the scheme that the diameters of the speed adjusting wheels 11 are different, the base for installing the speed adjusting wheel 11 is smaller due to the scheme that the diameters of the speed adjusting wheels 11 are the same, so that the structural cost of the rope supporting device speed adjusting device 1 of the present application can be effectively reduced, and the service lives of different first rope traction ropes 102 are not greatly different due to the same diameter of all the speed adjusting wheels 11, so that different first rope traction ropes 102 can be replaced at the same time, thereby greatly reducing the maintenance times of the first rope traction ropes 102 collectively and further reducing the maintenance cost.

Under the condition that all the speed regulating wheels 11 have the same diameter, the purpose of different linear speeds of the first wheel grooves 19 on at least two speed regulating wheels 11 is achieved by using different transmission ratios of at least two transmission mechanisms 14.

The transmission mechanism 14 may be a chain and sprocket transmission mechanism, a gear transmission mechanism or a synchronous belt transmission mechanism, and the positions of the rope supporters are efficiently adjusted by speed regulation control of the rope supporter speed regulation tractors.

Specifically, in one mode, the transmission mechanism 14 includes a driving sprocket 119 and a follower sprocket 16, the driving sprocket 119 is driven by a chain 17, the follower sprocket 16 rotates, the follower sprocket 16 and the corresponding flywheel 11 are coaxially disposed, the follower sprocket 16 and the corresponding flywheel 11 rotate together, the driving sprocket 119 is sleeved on the driving shaft 15, wherein the diameters of the driving sprockets 119 of at least two transmission mechanisms 14 are different, or the diameters of the follower sprockets 16 of at least two transmission mechanisms 14 are different. The aim of the transmission ratio difference of at least two transmission mechanisms 14 is achieved under the condition that all the speed regulating wheels 11 have the same diameter.

Specifically, the transmission mechanism 14 includes a driving gear and a follower gear, the driving gear drives the follower gear to rotate, the follower gear is coaxially disposed with the flywheel 11, the follower gear is rotatably disposed with the flywheel 11, the driving gear is sleeved on the driving shaft 15, and the driving gears or the follower gears of at least two transmission mechanisms 14 have different diameters.

On the basis of the above, in a further preferred manner, the traction sheave block 13 or the drive sheave block 120 further comprises a diverting sheave 18, taking the traction sheave block 13 as an example: the diverting pulley 18 and the governor wheel 11 are arranged at intervals, the diverting pulley 18 and the governor wheel 11 are arranged in parallel, at least two first wheel grooves 19 are arranged on the governor wheel 11, second wheel grooves are arranged on the diverting pulley 18, and the number of the second wheel grooves is one less than that of the first wheel grooves 19.

In order to ensure that the rope-in and rope-out force of the first cable pull rope 102 enables an efficient movement of the first cable pull rope 102, the first cable pull rope 102 is passed at least twice around the flywheel 11, at least two first pulley grooves 19 are provided on the flywheel 11, and a diverting pulley 18 is provided to cooperate so that the first cable pull rope 102 is passed at least twice around the flywheel 11. In a general construction situation, the number of the first wheel grooves 19 is two, and the first cable pulling rope 102 passes through one first wheel groove 19, then passes through the second wheel groove, and then passes through the other first wheel groove 19.

In order to control the rope inlet angle or the rope outlet angle of the rope supporting device speed regulating device 1, a first double-wheel structure 111 is arranged on one side of the diverting pulley 18 away from the speed regulating wheel 11, the first double-wheel structure 111 forms a first limiting space 115 for radial limiting of a rope supporting device traction rope, the first rope traction rope 102 penetrates through the first limiting space 115 and then is matched with the first wheel groove 19, so that the rope inlet angle or the rope outlet angle of the first rope traction rope 102 entering the speed regulating wheel 11 is always kept consistent, the first rope traction rope 102 is prevented from jumping out of the first wheel groove 19 due to the change of the rope inlet angle or the rope outlet angle, and meanwhile, the first rope traction rope 102 serving as the rope supporting device traction rope is prevented from jumping out of the first wheel groove 19 through the cooperation of the U-shaped limiter 118 and the first double-wheel structure 111.

In addition to the above, it is further preferable that the driving shaft 15 includes at least two coaxially disposed axles 112, a clutch 12 is connected between adjacent axles 112, the clutch 12 can separate the adjacent axles 112 from each other, and the transmission mechanism 14 is respectively connected to at least two axles 112 in a driving manner.

Because of the influence of the sag of the bearing cable 10 of the cable crane, the movement of a sports car, the engineering environment and the like, the position distance of each cable supporter on the cable crane is changed, and in order to prevent special situations in the construction process, the clutch 12 is arranged to realize the adjustment of each first supporting traction rope 102. Taking a jaw clutch as an example, when the operating handle 116 of the clutch 12 is released during the operation of each flywheel 11, the gears 117 engaged with each other on the clutch 12 are released, the respective flywheel 11 does not provide speed and allows free rotation, and when the clutch 12 is closed, the gears 117 connected between the adjacent axles 112 on the driving shaft 15 are engaged with each other, so that the axles 112 operate at a common angular speed. The axle 112 drives the flywheel 11 to rotate through the transmission mechanism 14, so as to ensure that the speed of each first supporting cable traction rope 102 meets the construction requirement.

During normal use, the clutch 12 is closed, all the wheel shafts 112 coaxially and integrally rotate, and then each traction pulley block 13 is driven to rotate, the traction pulley blocks 13 drive the corresponding first supporting rope traction ropes 102 to move, the first supporting rope traction ropes 102 drive the middle supporting rope devices 4 to move, so that the positions of the middle supporting rope devices 4 are accurately controlled, when a certain deviation exists between the actual positions of part of the middle supporting rope devices 4 and the preset design positions, the wheel shafts 112 corresponding to the deviated middle supporting rope devices 4 are separated from the adjacent wheel shafts 112 through the clutch 12, the wheel shafts 112 corresponding to the deviated middle supporting rope devices 4 are independently driven to rotate through manual or auxiliary power equipment, so that the deviated middle supporting rope devices 4 are adjusted to the preset design positions, then the clutch 12 is closed, all the wheel shafts 112 coaxially and integrally rotate, then normal operation is continued, and the positions of part of the middle supporting rope devices 4 are independently adjusted through the clutch 12, so that the deviation of the positions of the middle supporting rope devices 4 can be timely corrected after the deviation occurs, and a good deviation correction effect of the middle supporting rope devices is ensured.

Meanwhile, when the rope supporting device speed regulating device 1 has deviation, each span middle rope supporting device 4 cannot run at a specified speed, so that the adjacent span middle rope supporting devices 4 collide, the clutch 12 at the corresponding position can be opened, the traction speed of the traction pulley block 13 is not provided for the corresponding wheel shaft 112, the continuous extrusion collision of the adjacent span middle rope supporting devices 4 is avoided, and the working safety of the span middle rope supporting devices 4 is guaranteed.

In the rope-supporting speed-regulating device 1 of the embodiment, the driving shaft 15 is reasonably arranged to drive all the speed-regulating wheels 11 so as to realize synchronous speed regulation between the first rope-supporting traction ropes 102. Because of the influence of the sag of the bearing cable 10 of the cable crane, the movement of a running vehicle, the engineering environment and the like, the position distance of each cable supporter on the cable crane is changed, and in order to prevent special situations in the construction process, the clutch 12 is arranged to realize the adjustment of each first supporting traction rope 102.
