The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

In an embodiment of the present invention, a complex phase spacer installation apparatus is provided, referring to fig. 1 to 5, the complex phase spacer installation apparatus includes: the walking device 110, the walking device 110 includes a rolling wheel 1101 which is used for striding over the cable 1 and is matched with the cable 1 in a rolling way;

a mounting device 120, the mounting device 120 being used for mounting the complex phase spacer 20;

a control unit 130 for controlling the traveling device 110 and the mounting device 120;

a base 140, the base 140 being used to hold the walking device 110, the mounting device 120 and the control unit 130.

Since the base 140 holds the walking device 110, the mounting device 120, and the control unit 130. Wherein, the rolling wheel 1101 of the walking device 110 rolls on the cable 1 to advance to drive the complex phase spacer installation equipment to move; the mounting device 120 is used for mounting the complex phase spacer 20; the control unit 130 controls the traveling device 110 and the mounting device 120. The complex phase spacer mounting equipment in the embodiment has a simple structure, can greatly improve the mounting efficiency of the complex phase spacer 20, and can reduce the personnel safety risk in the mounting process of the complex phase spacer 20.

It should be noted that the control unit 130 can control the traveling device 110 to travel to a predetermined position on the cable 1 and brake the rolling wheel 1101, so that the complex phase spacer mounting apparatus stays at a designated position on the cable 1, and the control unit 130 controls the mounting device 120 to mount the complex phase spacer 20 which is already equipped. The roller wheel 1101 of the walking device 110 may be directly driven by a motor, or a direct in-wheel motor may be installed in the roller wheel 1101.

In some embodiments, referring to fig. 4 and 5, the walking device 110 includes a first motor 1102 and a first transmission mechanism 1103, and the first transmission mechanism 1103 couples the first motor 1102 with the scroll wheel 1101. The typical motor speed is too fast and may slip or wash directly out of the cable 1 if the roller wheel 1101 is driven directly. The first drive mechanism 1103 can be a variety of structures to effect linkage between the first motor 1102 and the scroll wheel 1101. For example, a gear drive, a chain drive, a belt drive, a worm gear drive or a cam drive, etc.

In certain specific embodiments, the first drive mechanism 1103 includes a reduction mechanism 1103 that is comprised of a plurality of gears. The gears are simple transmission structures, and can finish the effects of reducing the rotating speed and improving the torque of the rolling wheel 1101 according to the number of teeth of different gears. The complex phase spacer installation equipment can walk on the cable 1 with a certain slope.

In certain specific embodiments, the mounting device 120 comprises:

a closing structure, which can close the movable hand 210 and the fixed hand 220 at the two ends of the complex phase spacer 20;

and a locking structure, wherein the locking structure enables the bolts 250 at both ends of the complex phase spacer 20 to rotate through the preset screw holes 240 of the movable hand 210 and the fixed hand 220 and fix the movable hand 210 and the fixed hand 220.

Referring to fig. 1, 6 and 7, the two ends of the complex phase spacer 20 are respectively provided with a movable hand 210 and a fixed hand 220, and the fixed hand 220 is lapped on the cable 1 and slides along the cable 1. When the complex phase spacer 20 moves to a designated position on the cable 1, the closing movable hand 210 and the fixed hand 220 are closed, and after the movable hand 210 and the fixed hand 220 are closed, the complex phase spacer 20 cannot move on the cable 1. After the movable hand 210 and the fixed hand 220 are closed, the movable hand 210 and the fixed hand 220 are closed to form corresponding screw holes 240, and the screw holes 240 are screwed in by bolts 250, so that the movable hand 210 and the fixed hand 220 are closed to always keep a closed state. Finally, the complex phase spacer 20 is fixed at a certain position on the cable 1.

In this embodiment, the mounting device 120 closes the movable hand 210 and the fixed hand 220 through the closing structure, and the bolt 250 is screwed into the screw hole 240 through the locking structure to complete the screwing action, so as to lock the movable hand 210 and the fixed hand 220.

In some specific embodiments, the closing structure includes an electric telescopic rod 1201, the electric telescopic rod 1201 can be extended and retracted and abut against the movable hand 210, so that the movable hand 210 abuts against the fixed hand 220, and the electric telescopic rod 1201 is controlled by the control unit 130. The electric telescopic rod 1201 is a standard component, and is easily purchased from the market, and the purpose of closing the movable hand 210 and the fixed hand 220 in the embodiment is achieved.

The closing structure may also adopt other forms to achieve the purpose of closing the movable hand 210 and the fixed hand 220. For example, the purpose of closing the movable hand 210 and the fixed hand 220 is achieved by a motor, a lead screw and a slider structure. Specifically, a lead screw and a guide rod are disposed on the base 140, and the slider is disposed through the lead screw and the guide rod. The motor rotates the screw rod to enable the sliding block to move up and down on the screw rod, the sliding block can abut against the movable hand 210, and the movable hand 210 and the fixed hand 220 are closed. Alternatively, the movable hand 210 is abutted and closed with the fixed hand 220 by a cam or the like.

In certain specific embodiments, the locking structure includes a socket wrench 1202 and a second motor 1203 that drives the socket wrench 1202, and the socket wrench 1202 fixedly couples the fixed hand 220 and the moveable hand 210 by rotating the bolt 250. Bolts 250 are typically hex bolts and socket wrench 1202 may be adapted to accommodate bolts 250 of different sizes. If a general wrench is used, the wrench and the bolt 250 need to be completely matched, and when the wrench shakes out the screw hole 240 during the movement of the complex phase spacer mounting apparatus, there is no way to rotate the bolt 250 again. The socket wrench 1202 prevents the above situation, and even if the socket wrench 1202 is shaken out and falls on the bolt 250, the bolt 250 can be rotated.

In some specific embodiments, referring to fig. 5, the locking structure further includes a second transmission structure, the second transmission structure is used for linking the second motor 1203 and the socket wrench 1202, the second transmission structure is a worm 1204 arranged on the worm 1204 of the second motor 1203 and a worm 1205 matched with the worm 1204, and the worm 1205 is fixedly connected with the socket wrench 1202. The bolt 250 can also be tightened by directly driving the socket wrench 1202 by the second motor 1203, but the rotation speed of the second motor 1203 is too high and the torque is too low, so that it may not be possible to tighten the bolt 250 into the screw hole 240 well. In this embodiment, by the structure of the worm gear, the torque of the socket wrench 1202 can be increased, and the torque output direction of the second motor 1203 can also be changed, so that the locking structure is more concise.

It should be noted that the second transmission structure can also be implemented by other specific structures. For example, a gear structure composed of a plurality of gear sets.

In some specific embodiments, please refer to fig. 5, further comprising a pinch device 150 and a pinch roller 1504 located below the cable 1, wherein the pinch roller 1504 is disposed on the base 140, and the pinch device 150 can control the pressure between the pinch roller 1504 and the cable 1. The pinching device 1504 urges the pinching roller 1504 to rise against the cable 1, and the pressing force between the cable 1 and the roller 1101 becomes large, so that the rolling friction force of the roller 1101 and the cable 1 becomes large.

In the present embodiment, since the rolling friction of the rolling wheel 1101 with the cable 1 becomes large, the complex spacer mounting apparatus 10 does not slip while running on the cable 1, especially on the cable 1 having a certain inclination angle. It should be noted that the pinch rollers 1504 may be other pinching objects, such as pinching blocks. In practice, the cable 1 is mostly twisted from a plurality of strands of thinner cable, which are avoided by friction breaking using the pinch rollers 1504. The pinch roller 1504 is generally provided not directly below the scroll wheel 1101, but in the vicinity of the cable 1 below the scroll wheel 1101. This arrangement prevents the pinch roller 1504 from interfering with the rolling of the scroll wheel 1101.

It should be noted that the cooperation of the pinch rollers 1504 and the pinch device 1504 can also serve as a brake. When the multiple phase spacer mounting apparatus 10 is located somewhere on the inclined cable 1, pinching the cable by the pinch roller 1504 may increase the static friction between the roller wheel 1101 and the cable 1.

In certain embodiments, the pinching apparatus 150 includes a third motor 1501, a gear 1502, and a rack 1503 coupled to the gear 1502, wherein the third motor 1501 drives the gear 1502, the gear 1502 drives the rack 1503, and the pinching wheel 1504 is rotatably coupled to the rack 1503. The cooperation of gear 1502 and rack 1503 allows for easy control of the pressure between pinch wheel 1504 and cable 1.

In this embodiment, the pressing device 150 may also adopt other structures to realize the up-and-down movement of the pressing wheel 1504. For example, the vertical movement of the pinch roller 1504 is achieved using a conventional lead screw arrangement. Alternatively, a cam structure is used to achieve the up and down movement of the pinch rollers 1504. Or the compressing wheels 1504 can move up and down in the form of an electric telescopic rod. The structure of the pressing device 150 is various, and it is within the scope of the present invention that the pressing force between the pressing wheel 1504 and the cable 1 can be changed.

In some specific embodiments, the camera 160 is further included, the camera 160 is controlled by the control unit 130, and the camera 160 can rotate and can wirelessly transmit images. The camera 160 can be controlled by a remote control end to rotate, so that an installer can know the field environment in real time and give a corresponding operation instruction. In some cases, balancing of the complex phase spacer mounting apparatus 10 on the cable 1 may also be achieved by adjusting the orientation of the camera.

In some embodiments, referring to fig. 1, a hanging structure 1401 is disposed above the base 140, and the hanging structure 1401 can hang the base 140. The cable 1 is generally arranged on a very high iron tower, and a worker difficultly climbs and carries the complex-phase spacer installation equipment 10 to the iron tower. Usually, a worker climbs to the cable 1 on the iron tower and then hangs the cable on the hanging structure 1401 above the base 140 by using a hanging and pulling device, so as to move the whole complex phase spacer installation apparatus 10 to the required installation complex phase spacer 20 on the iron tower.

In some specific embodiments, an adjusting hole 1403 is provided below the base 140, and the adjusting hole 1403 is used for penetrating a rod-shaped object to adjust the multiphase spacer installation apparatus and to mount the rolling wheel 1101 on the cable 1. When the worker erects the multiphase spacer mounting apparatus 10 on the cable 1, both the rolling wheel 1101 and the fixing hand 220 of the multiphase spacer 20 need to be hung on the cable 1. Since many cables are charged, it is generally impossible for a worker to mount them directly by hand, and the installation of the complex phase spacer mounting apparatus 10 on the cable 1 is accomplished by inserting an insulating rod into the adjustment hole 1403 under the base 140 and then operating the insulating rod. Or the multiphase spacer installation apparatus 10 is not only erected on the cable 1 but also the socket wrench 1202 of the installation device 120 is just seized on the bolt 250 by firstly hanging the multiphase spacer 20 on the cable 1 and then inserting the insulation rod into the adjustment hole 1403.

In some embodiments, the cable 1 at each end of the complex phase spacer 20 has at least one running gear 110, a mounting gear 120, a hold-down gear 150, and a hold-down wheel 1504. Such a design can make the whole multiphase spacer installation apparatus 10 have stronger power, and make the multiphase spacer installation apparatus 10 also be able to move on the cable 1 with a larger inclination angle.

It should be noted that the control unit 130 may be one that can also control all of the walking device 110, the mounting device 120 and the pressing device 150. The traveling devices 110 straddling two different cables 1 can be driven by the same first motor 1102, and only the two rolling wheels 1101 need to be connected by bearings. Of course, it is preferable to use two first motors 1102 so that the power to the scroll wheel 1101 is stronger.

The closing structure and the locking structure on the installation device 120 can also be designed on one side of the cable 1, and the closing and locking actions on the complex phase spacer 20 can be completed simultaneously through the linkage structure.

The pressing device 150 may be designed only on one side of the cable 1, and both sides may simultaneously control the pressing wheels 1504 through a linkage structure.

Generally, the running gear 110, the mounting gear 120 and the pressing device 150 are respectively disposed on the cables 1, because the cables 1 swing, and the linkage structure between the cables 1 on both sides is easily damaged by the tension and pressure existing between the cables 1.

In certain embodiments, the cables 1 at either end of the complex phase spacer 20 are provided with at least two mounting devices 120. Two mounting means 120 may enable two complex phase spacers 20 to be mounted at a time.

In some specific embodiments, the base 140 has two, the walking device 110, the mounting device 120, the pressing device 150 and the pressing wheel 1504 of the base 140 under the support of each cable 1, the base 140 is connected by a connecting rod 1402, and the length of the connecting rod 1402 is adjustable. The function of the connecting stick 1402 is mainly to keep the traveling unit 110, the installation unit 120, the pressing unit 150, etc. on both sides of the cable uniform. The telescopic structure is adopted to counteract the tension and pressure on the connecting rod 1402 caused by the swing between the two cables 1.

Finally, it should be noted that a battery may be provided on the base 140 for powering the multiple phase spacer apparatus 10.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent should be subject to the appended claims.
