Detailed Description

The following describes in detail preferred embodiments of the present invention. It should be noted that the following description is only illustrative of the patented implementation of the invention and should not be taken as limiting the scope of the invention.

The preferred embodiment of the device for applying high voltage to a self-traction hoisting double-traction rope is shown in fig. 1, and the basic implementation structure is on a platform base 110, the platform base 110 can be provided with a flat plate structure or a frame structure, as shown in fig. 1, a platform base formed by a plurality of laths side by side is used, one or more laths can be provided with mounting holes 101 for assembling other working units, and the mounting holes 101 can be assembled with other units according to actual needs, such as but not limited to a spraying robot 300 for spraying insulating layer paint on a cable, as shown in fig. 6 and 7.

At least two sets of suspension wheels 120, as shown in fig. 2-5, which may be, but not limited to, three or four sets, for example, are disposed on the platform base 110, and the suspension wheels 120 are fixed on the platform base through a rotating shaft 121 and a seat frame 122, and rotatably wind a suspension belt 130, as shown in fig. 1. The hanging wheels 120 are provided with inner grooves 123 recessed inwards for winding the hanging strips 130, and two hanging wheels 120 are arranged in each group and arranged side by side. The strap 130 may be, but is not limited to, a variety of tough materials such as a belt, a woven tape, etc., and may be used with a strap having a weighing capacity selected according to the weighing requirements of the work apparatus. The harness 130 is used to suspend the dual pull-cord lift platform assembly from a cable 200, as shown in FIG. 1.

When the platform is in operation, each group of the suspension wheels 120 are controlled to rotate in opposite directions, that is, when the suspension wheels 120 are controlled to rotate, the same group of the suspension wheels 120 rotate inwards or simultaneously rotate, and are wound into the suspension belts, so that the platform base body is driven to ascend; or simultaneously rotate in an outward direction, synchronously release the sling, and accordingly release the platform base to descend downwards. The depth of the inner groove 123 is set according to the height requirement of construction and the winding thickness of the hanging strip, so as to ensure that the inner groove can be lifted to a sufficiently high height. For each cable, the length of the sling needs to exceed two times of the height of the cable, so that the hoisting can be conveniently realized.

The harness 130 can be passed over the cable 200 at one end by an auxiliary tool, such as a drone or a parabolic implement, and drawn into the corresponding side suspension wheel, and then wound onto the corresponding suspension wheel by a corresponding control and power drive.

The power drive generally adopts a first motor, and the first motor can adopt any drive mode, such as belt or gear drive, or coaxial first motor drive; in the embodiment shown in fig. 1, each suspension wheel 120 is coaxially driven by a corresponding first motor 124 through a rotating shaft 121, and each first motor 124 is respectively controlled by a control system (not shown in the figure, a control circuit and a control system) so that the synchronous retraction and retraction of the suspension belts of each group of suspension wheels can be realized through the control instruction of the control system.

Meanwhile, in the lifting process of the platform base body, an unstable state of the movement of the platform base body is easy to occur, and the unstable state may be an external influence, such as the blowing of wind to the equipment or a cable, or a shaking influence of the suspension wheel 120 on the platform base body caused by the controlled synchronous retraction of the suspension belt. In a preferred embodiment of the present invention, a corresponding dynamic sensor, such as a gyroscope sensor, may be further disposed on the platform substrate, so as to sense the dynamic state of the platform substrate, and a corresponding logic function is preset in the function setting of the control system, for example, the respective rotation modes of the four suspension wheels 120 are adjusted according to the direction and amplitude of the vibration, so as to fine-tune and maintain the stable state of the platform substrate.

In order to facilitate the arrangement of the center of gravity of the device for applying high voltage to the self-traction hoisting double-traction rope, the four suspension wheels 120 and the arrangement mode of the four suspension wheels corresponding to the first motor 124 are shown in fig. 1, but not limited to the adoption of a centrosymmetric mode, namely, the arrangement positions of the suspension wheels and the first motor on the same side of the two groups of suspension wheels 120 are along the same direction, but are opposite to the arrangement positions of the suspension wheels and the first motor on the other side, and the center of gravity of the whole platform device is arranged in the center, so that the rotation control of the suspension wheels is facilitated, and the dynamic stable balance of the whole platform device is kept and controlled; this arrangement also advantageously allows one of the first motors to be suspended, reducing the space occupied by the platform substrate 110, such as the first motor 125 shown in FIG. 1.

In the case that the platform base 110 has a relatively wide space, other symmetrical arrangement manners may also be adopted, for example, the first motors of each set of suspension wheels are arranged on the same side, and the suspension wheels on the same side between the two sets are arranged in opposite directions, that is, all the first motors are arranged between the suspension wheels, or all the suspension wheels are arranged between the first motors.

In the preferred embodiment of the present invention, as shown in fig. 1, in order to facilitate the cooperative winding of the hanging strip 130 and the hanging wheel 120 and prevent the problem that the hanging strip is wound or pulled off from the edge of the hanging wheel during the winding process, a guide assembly 140 is further disposed at the position where the hanging strip 130 enters the hanging wheel 120, as shown in fig. 1 and 2. The engagement between the hanging band 130 and the hanging wheel 120 is not limited to the winding from the inside in the drawing, and may be the winding from the outside at the same time.

The guide assembly 140 of the present invention, as shown in fig. 1, is disposed to penetrate through one side, i.e., the inner side, between two suspension wheels 120 of the same set, and is provided with a damping rod 141, as shown in fig. 2, clamped between the suspension belt 130 and the suspension wheels 120, and a frame is formed at both ends and the outer side of the damping rod 141, and a guide hole for allowing the suspension belt to pass through is formed in the frame. The damping rod 141 can also adopt a roller arrangement mode so as to reduce the wear of the sling. A second rail 142 is provided at an outer side of the frame, that is, an outer side of the strap, in parallel with the damping bar 141, so as to restrict the winding process of the strap 130 from being smoothly performed. That is, the strap 130 can pass through the gap between the damping rod 141 and the second rail 142 to ensure the safety and smoothness of the winding process.

In another preferred embodiment of the dual-pull-cord elevating platform assembly of the present invention, at least one working boom 150, preferably two working booms, is further disposed on the platform base 110, and the working booms can be disposed on two sides of the platform base according to the distribution space of the suspension wheels and the first motor on the platform base, preferably adjacent to the suspension wheels 120 and symmetrically distributed with respect to the center of the platform base as shown in fig. 1. In the preferred embodiment as shown in FIG. 1, two of the working booms 150 are disposed diagonally on the platform substrate 110.

A corresponding pulley 151 is provided at the top end of the working boom 150 toward the inside direction between the two suspension wheels of the same set (the direction facilitating the engagement of the cable), and a groove 152 for engaging the cable 200 is provided on each pulley 151. The working boom 150 may be configured to be fixed with the platform substrate, and the pulley 151 may be configured to be a support arm structure extending outward from the working boom 150, so as to adjust the pulley 151 to be adapted to the cable 200, thereby forming a state convenient for the working device on the platform substrate to work, such as spraying a coating on the cable or removing an obstacle.

In the case of one working boom 150, the pulleys may be provided in more than two, arranged in the cable direction, one of which serves as the active driving wheel, for example, by using the pulley arrangement on the working boom 150, by using the driving first motor, and by using further pulleys on one or both sides of the working boom in the cable direction (the cable direction being substantially perpendicular to the working boom and parallel to the platform base surface), and by extending the boom from the working boom for arranging these further pulleys.

In the preferred embodiment of the present invention, the working boom 150 is arranged in a manner that one side of the bottom of the working boom is hinged to the working base 110, and a telescopic rod 153 is arranged at the outer side of the working boom 150, as shown in fig. 1, one end of the telescopic rod 153 is hinged to the top end of the working boom 150, and the other end is hinged to the working base 110, and the control of the telescopic rod 153 can control the inclination angle of the working boom 150, so that when the platform device is lifted to the working position by the hanging strip 130, the two working booms 150 are opened, the cable 200 is conveniently moved to a position lower than the pulley 151, then the pulley at the front end of the working boom 150 can be moved to the upper side of the cable 200 by controlling the telescopic rod 153, and then the cable can be clamped on the pulley 151 by releasing the hanging strip, thereby facilitating the maintenance of the hanging position and the corresponding movement during the work. The telescopic rod 153 may specifically, but not exclusively, be implemented as a hydraulic rod.

The pulley 151 may also be provided with a second motor 154 for driving the active rotation thereof, as shown in fig. 1, thereby facilitating the movement of the integrated dual pull-cord lift platform assembly and the associated working equipment along the cable during operation.

In order to prevent obstacles on the cable, such as kites, plastic cloths, etc. that may be present on the cable 200 during the movement of the platform assembly along the cable and, during operation, due to the damping frictional resistance of the harness and the cable, which may be moving late, a V-shaped open protection flap 155 is also provided between the pulley 151 and the cable 200 on the front side of the pulley, i.e. on the side close to the center of the platform base in the direction of movement of the cable along the double traction rope lifting platform assembly, as shown in fig. 2, which protection flap 155 may be provided integrally with the working boom 150 and in front of the inner groove of the pulley 151 so as to push away obstacles on the cable during operation. The V-shaped opening of the protective plate 155 does not need to grip the cable and therefore, the position at which it is disposed needs to be carefully determined in advance to prevent the structure of the protective plate 155 from causing a wear damage to the cable 200 or causing difficulty in moving the platform assembly during operation. It should be noted that the protection sheet 155 is not limited to the one-side arrangement, and the protection sheet 155 may be disposed on both sides of the pulley 151.

In the platform device for implementing the above various preferred embodiments, the present invention also provides a preferred embodiment of a method for implementing the lifting of a dual-pull-rope lifting platform device, as shown in fig. 6, which includes the following steps:

step one, the sling is wound from the upper part of the cable, and then two ends of the sling are threaded into two hanging wheels in the same group. Specifically, the sling 130 can be pre-wound on one suspension wheel 120, the sling of the corresponding length can be released from the suspension wheel, the free end of the sling can be passed over the overhead cable by a corresponding auxiliary tool, such as a drone or an ejection device, and finally dropped and wound on another suspension wheel of the same group, and the respective winding lengths of the two suspension wheels can be pre-adjusted to ensure the bearing capacity and safety during the work process. When the two groups of suspension wheels are just lifted off the ground, the platform device is at the initial stage of lifting.

And step two, starting and controlling the synchronous operation of the two groups of suspension wheels, wherein the two suspension wheels in each group of suspension wheels rotate in opposite directions, and the synchronous winding sling can move the double-traction-rope lifting platform device to the aerial cable direction. In the moving process, in order to ensure the stable movement of the double-traction-rope lifting platform device, the antagonistic adjustment of the suspension wheels can be realized through the sensor arranged on the platform base body and the fine adjustment control of the control system, so that the mixed movement of the platform is reduced, the swing amplitude of the platform is reduced, the influence of external factors such as wind and cable vibration or the influence of the lifting process of the platform device is reduced, and the stable lifting of the whole platform device is kept as much as possible. The rotation of the suspension wheel is controlled in the opposite direction, so that the release of the suspension belt can be controlled, and the descending process of the platform device is controlled, which is not described in detail herein.

And step three, controlling the rotation of the suspension wheel, winding the suspension belt, lifting the platform device to a position high enough, wherein the cable is positioned right above the platform base body and lower than the end part of the working suspension arm, so that the pulley is higher than the cable, and at the moment, the position of the pulley can be adjusted, and the pulley is clamped and matched above the cable. More than two pulleys are provided, for example, as shown in the drawings of the invention, in the illustrated embodiment, two working booms are symmetrically provided, and the working booms can rotate towards one side of the pulleys relative to the working base body under the control of the telescopic rod 153, so that the pulleys at the ends of the two working booms can be respectively aligned with the cable and clamped and matched on the cable.

Therefore, the device for the high voltage wire on the self-traction winch double-traction rope can realize the moving working process on the cable by using the pulleys of the two working suspension arms, and in the working process, the hanging belt only exists as a safety precaution measure and does not play a main hanging role. Of course, in some embodiments, depending on the weight of the suspended work equipment, such as an excessively heavy work equipment, the timing of the suspension straps to perform the primary or secondary suspension functions may also be controlled.

During movement in a working process, such as spraying or obstacle clearing, the double-pull-rope lifting platform device provided by the invention mainly realizes the movement on the cable through the active rotation driving of at least one pulley. When the platform device moves, a certain friction resistance exists between the sling and the cable, and the certain friction resistance and the passive movement possibly lag behind the moving position of the platform device, at the moment, the platform device provided by the invention realizes the pushing of the sling 130 by arranging the protective sheet 155 on the front side of the pulley, and the protective sheet 155 not only pushes the movement of the sling 130, but also can push all obstacles on the cable to prevent the obstacles from being clamped between the pulley and the cable, so that the work is prevented, and the damage to the platform device is caused. In a preferred arrangement, the protective pieces 155 with the V-shaped openings are disposed on both the front and rear sides of the pulley 151, so that the moving direction of the dual-traction-rope lifting platform device can be changed, the dual-traction-rope lifting platform device can move forward or backward in a controlled manner, and the pulley can be safely moved on the cable.

According to the device and the method for the high voltage wire on the self-traction winch double-traction rope, the suspension wheel and the working suspension arm are arranged, so that a mode that a platform device can work by cable loading when the platform device is operated on the ground is realized, and the mode for realizing the operation is safe and convenient; meanwhile, in the working process of working equipment borne by the platform, the pulleys on the platform base body can keep adaptation with cables, so that the operation convenience and safety in the construction and maintenance process are ensured.

It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are intended to be included within the scope of the invention as defined in the appended claims.
