Description

Technical Field

[0001] This invention relates to the field of maintenance equipment for multi-split transmission lines, specifically to a multifunctional maintenance platform and method for multi-split transmission lines. Background Technology

[0002] Multi-split transmission lines (such as four-split, six-split, and eight-split lines) are the core carriers of ultra-high voltage / extra-high voltage power grids, and their safe operation depends on regular maintenance. Traditional maintenance methods face the following bottlenecks: First, high-altitude operations are risky, as maintenance must be carried out on conductors tens of meters above the ground, requiring personnel to climb or use pulleys for movement, posing risks of falls and electric shock; Second, coordinated operation of split sub-conductors is difficult, as the spacing between multiple sub-conductors is fixed, and existing platforms cannot simultaneously cover adjacent sub-conductors, leading to frequent traversal and relocation of personnel, increasing the risk of imbalance and loss of control; Third, there are significant limitations on the carrying of tools and equipment, requiring maintenance to carry heavy equipment such as crimping equipment, X-ray flaw detectors, and ultraviolet imagers, while traditional maintenance platforms lack sufficient load-bearing capacity and cannot provide stable position adjustment capabilities.

[0003] Therefore, how to construct a maintenance platform that can accommodate tools while maintaining their position, thereby effectively demonstrating the collaborative effect of maintenance work and improving maintenance efficiency, has become an urgent problem to be solved in the field of maintenance equipment for multi-split transmission lines. Summary of the Invention

[0084] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0085] Example 1:

[0086] like Figures 1-8 As shown, a multi-functional maintenance platform for multi-split transmission lines includes a support frame 3, and a first lifting component 1 and a second lifting component 13 are provided inside the support frame 3. The lifting trajectory of the first lifting component 1 and the lifting trajectory of the second lifting component 13 are staggered.

[0087] The first lifting assembly 1 is provided with a first mounting platform 7, and the second lifting assembly 13 is provided with a second mounting platform 8;

[0089] The bearing frame 3 is fixed with a first base platform 17 and a second base platform 14, and the second base platform 14 avoids the first base platform 17 in the vertical direction;

[0090] The first lifting assembly 1 is fixed on the first base platform 17, and the second lifting assembly 13 is fixed on the second base platform 14;

[0091] The bearing frame 3 is further fixed with a walking mechanism, which is used to drive the bearing frame 3 to reciprocate.

[0092] In actual operation, the position of the walking mechanism is adjusted so that the walking mechanism can effectively carry the bearing frame 3 to reciprocate, and on this basis, the first mounting platform 7 and the second mounting platform 8 are installed with maintenance equipment such as a ray machine, a detector, a mechanical arm, a maintenance hand and / or a de-icer, and the characteristics of the maintenance equipment are adjusted according to the characteristics of the first mounting platform 7 and the second mounting platform 8.

[0093] The first lifting assembly 1 controls the height of the first mounting platform 7, and the second lifting assembly 13 controls the height of the second mounting platform 8, and the corresponding maintenance equipment is carried to the corresponding maintenance position by using the rotation adjustment capability of the first mounting platform 7 and the horizontal movement capability of the second mounting platform 8, and when selecting the first mounting platform 7 and the second mounting platform 8, the first mounting platform 7 or the second mounting platform 8 should be selected according to the characteristics required by the maintenance equipment to carry the maintenance equipment, so that the first mounting platform 7 and the second mounting platform 8 can effectively play the maintenance function of the maintenance equipment.

[0094] The walking mechanism includes a first limiting track 4 and a second limiting track 12, and the first limiting track 4 and the second limiting track 12 are symmetrically distributed on the bearing frame 3;

[0095] A plurality of first wheel body hangers 5 are detachably fixed on the first limiting track 4, and the first wheel body hangers 5 are each installed with a first driving wheel 6;

[0096] A plurality of second wheel body hangers 11 are detachably fixed on the second limiting rail 12, and a second traveling wheel 10 is installed on each second wheel body hanger 11, and a locking assembly 9 is also installed on the second wheel body hanger 11, and the locking assembly 9 can abut against the second traveling wheel 10 and stop the second traveling wheel 10.

[0097] The locking assembly 9 comprises a telescopic rod 91, one end of which is fixed with the second wheel body support, and the other end is provided with a hinged end head 92, the side surface of the second wheel body support is fixed with a limiting frame 93, the limiting frame 93 is hinged with the side surface of the hinged end head 92, and the telescopic rod 91 is hinged with the end of the hinged end head 92;

[0098] The other end of the hinged end head 92 away from the telescopic rod 91 is fixed with an arc-shaped rod 94, which extends in the direction of the second traveling wheel 10;

[0099] The end of the arc-shaped rod 94 is fixed with a friction roller 95.

[0100] According to the actual situation of the power transmission conductor, the positions of the first wheel body support and the second wheel body support in the embodiment are adjusted correspondingly, the unmanned aerial vehicle hanger 2 is connected with a suspension device such as an unmanned aerial vehicle or a boom, the embodiment is lifted to the upper side of the power transmission conductor, the first traveling wheel 6 and the second traveling wheel 10 are placed on the power transmission conductor, the load bearing of the power transmission conductor is effectively maintained, and the first traveling wheel 6 and the second traveling wheel 10 are used to transport the load bearing frame 3 to each detection position, so that the work of lifting and detecting multiple positions at one time is completed.

[0101] In the embodiment, the first limiting rail 4 and the second limiting rail 12 are symmetrically distributed with the center line of the bottom surface of the load bearing frame 3 as the center line, so that the gravity center can be controlled in the vertical area of the load bearing frame, so that the embodiment not only can use the frame structure of the load bearing frame 3 to bear the maintenance equipment, can use the frame structure to increase the movable range of the maintenance equipment, but also can guarantee the stability of the whole walking mechanism when moving.

[0102] When the embodiment needs to be stopped, the telescopic rod 91 is extended, the articulated end head 92 rotates around the limiting frame 93 under the push of the telescopic rod 91 and squeezes and pushes the arc-shaped rod 94 to swing towards the wheel surface of the second traveling wheel 10, the arc-shaped rod 94 pushes the friction roller 95 to press the power transmission cable contacted by the wheel surface of the second traveling wheel 10 to realize friction resistance stopping, the telescopic rod 91 is a pneumatic rod or a hydraulic rod, the articulated end head 92 is pushed by pneumatic or hydraulic action, since the end of the articulated end head 92 is hinged with the end of the telescopic rod 91 and the side of the articulated end head 92 is hinged with the limiting frame 93, the position of the articulated end head 92 does not change and rotates around the hinge between the limiting frame 93 and the articulated end head 92, the rotating behavior can push the arc-shaped rod 94 to swing and drive the friction roller 95 to press the power transmission cable contacted by the wheel surface of the second traveling wheel 10, thereby realizing the operation of friction stopping. During stopping, the overall stopping process can be stabilized by increasing static friction, and the surface of the cable can be prevented from being damaged by hard contact.

[0103] When the embodiment does not need to be stopped, the friction roller 95 can be used to assist the maintenance of stability, for example, during slope walking or when it is necessary to cross the strain clamp, the second traveling wheel 10 presses the cable thereon, and the friction roller 95 is used to abut against the cable below the second traveling wheel 10, thereby realizing bidirectional clamping of the cable, resisting the action of gravity by increasing static friction, avoiding the embodiment from sliding down on the slope, thereby effectively improving the actual climbing ability of the embodiment;

[0104] The improvement of the climbing ability mainly lies in that the wheel surface of the second traveling wheel 10 and the surface of the friction roller 95 simultaneously press the cable from two different directions of components, thereby continuously forming a clamped state of the cable during walking by relying on the rolling friction of two directions, more contact area can be used to improve the friction when climbing, thereby making the embodiment less likely to slide on the slope.

[0119] A connecting sliding end 729 is also provided, the sliding track group close to the detection carrying frame is slidingly connected with the connecting sliding end 729, and the connecting sliding end 729 is connected with the outside;

[0120] One end of the base track 724 is provided with a first power group, and the other end is provided with a second power group 7210, the first power group is used to pull the sliding track group to slide in the direction of the first power group, and the second power group 7210 is used to pull the sliding track group to slide in the direction of the second power group 7210.

[0121] The first power group and the second power group 7210 are the same in structure.

[0122] The first power group comprises an adjusting motor 722, the adjusting motor 722 is fixed with the base track 724, the adjusting motor 722 is connected with a driving wheel 723, and the adjusting motor 722 is used to drive the driving wheel 723 to rotate.

[0123] The end of the sliding track group is provided with a translation pulley 727, the driving wheel 723 is wound with a traction rope, the traction rope is serpentine extended and sequentially passes through the translation pulley 727 and is fixed with the end translation pulley 727, and the driving wheel 723, the traction rope and the translation pulley 727 form a plurality of series of movable pulley connections.

[0124] The sliding track group comprises a first translation track 725 and a second translation track 726, the first translation track 725 and the second translation track 726 are parallel to each other, and the first translation track 725 and the second translation track 726 are provided with a track connecting rod 728, one end of the track connecting rod 728 is fixed with the first translation track 725, and the other end is fixed with the second translation track 726.

[0125] The first translation track 725 is in sliding connection with the sliding seat 721, and the second translation track 726 is in sliding connection with the sliding seat 721 or the connecting sliding end head 729.

[0126] The translation pulley 727 comprises a base 7271, the base 7271 is fixed with the end of the sliding track group, a horizontal pulley 7272 is installed in the base 7271, a limiting rod 7273 is arranged on the side away from the sliding track group of the horizontal pulley 7272, and the limiting rod 7273 is fixed with the base 7271.

[0127] The sliding seat 721 comprises a first end head 7211 and a second end head 7213, a synchronous connecting rod 7212 is arranged between the first end head 7211 and the second end head 7213, one end of the synchronous connecting rod 7212 is fixed with the first end head 7211, and the other end is fixed with the second end head 7213.

[0128] The first end 7211 is in sliding connection with the base track 724 or the second translation track 726, and the second end 7213 is in sliding connection with the first translation track 725.

[0129] In the embodiment, when the horizontal movement telescopic frame 72 needs to be stretched in the direction of the first power group, the adjusting motor 722 is turned on, the driving wheel 723 rotates, and the traction rope continuously presses the translation pulleys 727 at the ends of the sliding track groups in turn when being tightened, thereby generating a pushing force on the translation pulleys 727. On this basis, the translation pulleys 727 can effectively push the sliding track groups to slide on the sliding seat 721 or drive the sliding seat 721 to slide together. When the sliding seat 721 is limited to stop at the end of the adjacent sliding track group, the subsequent adjacent sliding track group continues to slide until all the sliding track groups and the sliding seat 721 are located at the end in the same direction, and the complete expansion is completed.

[0130] When the horizontal movement telescopic frame 72 needs to be contracted or expanded in the direction of the second power group 7210, the adjusting motor 722 of the first power group is turned off, and the adjusting motor 722 of the second power group 7210 is turned on. The whole horizontal movement telescopic frame 72 moves in the opposite direction in the same manner, thereby driving the maintenance equipment in the opposite direction, and completing the adjustment of the horizontal position of the maintenance equipment.

[0131] If the sliding track groups are connected in the form of a single sliding rail, the sliding stroke is limited, and the stability is poor. The first translation track 725 and the second translation track 726 are combined in the embodiment, so that the sliding on the first translation track 725 and the sliding on the second translation track 726 are relatively independent, and the whole sliding stroke of the first translation track 725 and the second translation track 726 can be utilized. Therefore, in the embodiment, each sliding action does not affect each other.

[0132] On this basis, the two adjacent sliding track groups can realize sliding stroke connection through the fixed connection of the first translation track 725 and the second translation track 726, so that the expansion length of the horizontal movement telescopic frame 72 in the embodiment is longer, and the whole telescopic range of the embodiment is larger.

[0133] In the embodiment, the sliding rail group closest to the base rail 724 is adjusted as follows: first, the first end head 7211 is driven to slide on the base rail 724; when the first end head 7211 slides to the end of the base rail 724, the first translation rail 725 connected to the second end head 7213 is driven to slide on the second end head 7213 and the second translation rail 726 is synchronously driven to slide, the adjacent sliding seat 721 connected to the second translation rail 726 is driven to move along with the second translation rail 726, the sliding seat 721 on the second translation rail 726 stops sliding when the first translation rail 725 slides to the end of the second translation rail 726, and the subsequent sliding seat 721 and the sliding rail group are sequentially driven to slide. The driving force comes from the rotation of the driving wheel 723, which drives the traction rope to press the translation pulley 727, so that the first translation rail 725 and the translation pulley 727 at the end thereof form a movable pulley with the traction rope, and the second translation pulley 727 and the translation pulley 727 at the end thereof also form a movable pulley.

[0134] In the embodiment, the traction rope in the first power group and the traction rope in the second power group 7210 are independent of each other, so as to avoid mutual influence between the first power group and the second power group 7210.

[0135] In the embodiment, the base 7271 of the translation pulley 727 is used to support the horizontal pulley 7272, the orientation of the base 7271 is adjusted according to the actual insertion position of the traction rope, and the limiting rod 7273 is used to limit the traction rope on the horizontal pulley 7272, so as to avoid the traction rope from being separated from the horizontal pulley 7272 when the sliding direction changes.

[0136] Further, the first lifting telescopic frame 18 comprises a platform connecting frame 21 fixedly connected with the first base platform 17, a lifting frame body 22 fixed below the platform connecting frame 21, a plurality of groups of second sliding frame bodies 24 parallel to each other arranged in the lifting frame body 22, two adjacent second sliding frame bodies 24 slidably connected, a first sliding frame body 25 slidably connected in the second sliding frame body 24, a connecting seat body 28 fixed to the bottom of the first sliding frame body 25, a plurality of fixing frames 27 fixed on the connecting seat body 28, and a lifting pulley 26 arranged in each fixing frame 27.

[0137] The first cable is fixedly connected with the platform connecting frame 21, the rope in the first cable extends to and passes through the lifting pulley 26, and the first cable and the lifting pulley 26 form a movable pulley.

[0138] The lifting frame 22 is fixed with a plurality of transverse reinforcing ribs which circumferentially surround the lifting frame 22.

[0139] In the present embodiment, the lifting frame 22 is used to accommodate the second sliding frame 24 and the first sliding frame 25. Since the second sliding frames 24 are parallel to each other and are slidingly connected, and the first sliding frame 25 is slidingly connected with the second sliding frames 24, the first sliding frame 25 can slide downward by its own weight in the present embodiment. During the sliding of the first sliding frame 25 downward, the first cable and the lifting pulley 26 in the first lifting telescopic frame 18 form a movable pulley connection which can pull the first sliding frame 25 to slide downward. Therefore, the first sliding frame 25 needs to be pulled by the first cable to slide downward. When the first sliding frame 25 slides to the bottom end of the sliding connection with the second sliding frame 24, the second sliding frame 24 can be sequentially pulled to slide downward, thereby extending the telescopic length to enable the first sliding frame 25 to be lowered to a lower position. Since the connecting seat 28 is fixedly connected with the first sliding frame 25, the height of the maintenance equipment is determined by the height of the first sliding frame 25, and the height of the first sliding frame 25 is determined by the length of the rope released by the first cable. The length of the second sliding frame 24 can be extended to limit the range of the maintenance equipment.

[0140] In the present embodiment, the length of the first lifting telescopic frame 18 and the second lifting telescopic frame is increased by the adjacent two second sliding frames 24 which are slidingly connected and can form a longer connecting body by dislocation. Similarly, the first sliding frame 25 and the second sliding frame 24 can also form a longer connecting body by sliding dislocation. Therefore, the first sliding frame 25 and the second sliding frame 24 can be extended to a longer length range by sliding dislocation.

[0141] The height position of the first sliding frame 25 in the second lifting telescopic frame is determined by the length of the rope released by the second cable.
