[0052] See also Figure 1-14 The present invention describes the above technical solution in detail through the following embodiments:

[0053] A power transmission overhead line crossing construction device, used for lifting and crossing a power transmission line 1, comprising:

[0054] The lifting and moving part 4 is used to be installed on the frame column 2 and move along the frame column 2, including a moving cylinder 41 sleeved on the frame column 2 and three transmission components 42, a gear ring 44 and six brake units 45 installed inside the moving cylinder 41;

[0056] The line supporting part 5 includes a supporting plate 51 for supporting the transmission line 1 across the transmission line. A rotating disk 52 is installed below the supporting plate 51. The rotating disk 52 is rotatably installed above the moving cylinder 41.

[0057] like Figure 4As shown in the structure, in this embodiment, a triangular support block 22 and a base plate 21 are provided under the frame column 2, and three vertically arranged movable grooves 201 and a horizontally arranged anti-falling groove 202 are provided on the column body of the frame column 2; in order to obtain a stable moving grip, in this embodiment, rubber pads are provided in the three movable grooves 201, and the anti-falling groove 202 adopts an upwardly inclined groove opening. In order to prevent the device from sliding downward and falling off when being lifted across the transmission line 1, the anti-falling groove 202 can be clamped into the opening and closing component 33 during sliding to form a clamping structure.

[0058] like Figure 8 As shown in the structure, in this embodiment, an inner mounting cavity 4101 is provided inside the movable cylinder 41, and the gear ring 44 is rotatably mounted on the cavity wall of the inner mounting cavity 4101; an active driving gear 46 is rotatably installed in the inner mounting cavity 4101 by using a driving motor as a driving source, and the active driving gear 46 engages with the gear ring 44, and can drive the gear ring 44 to rotate.

[0059] In this embodiment, three groups of mounting holes 411 are provided on the outer wall of the moving cylinder 41, and three rotation grooves 412 are provided on the inner wall of the moving cylinder 41. The transmission assembly 42 is installed in the inner mounting cavity 4101; Figures 8 to 11 In the structure shown, each transmission assembly 42 includes a group of symmetrically arranged side fixing rods 421 and a fixedly connected connecting seat 422, a vertical shaft 423 is inserted on each side connecting seat 422, and a first bevel gear 425 is coaxially installed on the vertical shaft 423; a horizontal shaft 427 is rotatably installed between the connecting seats 422 on both sides, and a second bevel gear 426 meshing with the first bevel gears 425 on both sides is installed on the horizontal shaft 427, and a wheel body 43 corresponding to the rotating groove 412 is coaxially installed on the horizontal shaft 427; wherein the wheel body 43 of this embodiment is protrudingly arranged at the rotating groove 412, so that the wheel body 43 can move along the moving groove 201 in contact;

[0060] like Fig.10 and Fig.11 In the structure shown, a first gear 424 is coaxially mounted on a vertical shaft 423 on one side, and the first gear 424 is meshed with a gear ring 44; a reversing gear 428 is coaxially mounted on the vertical shaft 423 on the other side, and the reversing gear 428 is meshed with the gear ring 44 through a second gear 429; in order to ensure that the rotation direction is consistent, a reversing gear 428 is provided in this embodiment.

[0061] like Fig.12 and Fig.13As shown in the structure, the brake unit 45 in this embodiment includes a fixed support rod 451 with a pawl 453 installed, and a ratchet 452 coaxially installed on the horizontal shaft 427; the fixed support rod 451 is installed on the inner mounting cavity 4101, and the fixed support rod 451 is provided with a conducting inner cavity 4512 and a movable slide groove 4511 for slidingly installing the pawl 453; a push rod 455 is vertically inserted in the conducting inner cavity 4512, and a second return spring 454 is installed between the push rod 455 and the pawl 453; when moving upward, the ratchet 452 rotates and there is no blockage between the pawl 453. During the downward movement, the pawl 453 is squeezed by the rotating ratchet 452, and under the contraction of the second return spring 454, the push rod 455 is pressed downward, and during this process, the pawl 453 retreats along the movable slide groove 4511, and does not hinder the rotation of the ratchet 452 during the downward movement; at the same time, during this process, the pawl 453 will be reset under the action of the second return spring 454 to repeat the above action.

[0062] The opening and closing assembly 33 includes three opening and closing unit plates 331, a rotating connecting block 333 is installed on the outer side of the opening and closing unit plate 331, and a mounting seat 311 is provided at the bottom of the mounting cover 31, and the rotating connecting block 333 can be rotatably installed on the mounting seat 311; a conducting groove 3101 for the movement of the extrusion block 32 is provided inside the mounting cover 31, and the extrusion block 32 is provided with a movable cavity 3201 and a mounting groove 321; a connecting protrusion 3311 corresponding to the position of the mounting groove 321 is provided on the opening and closing unit plate 331, and the connecting protrusion 3311 is connected to the extrusion block 32 through a first reset spring 332.

[0063] The six push rods 455 of this embodiment are inserted through the movable cylinder 41 and connected to the extrusion block 32. Based on the action of the pawl 453 during the downward movement, the push rod 455 will press down the extrusion block 32, and then open the opening and closing unit plate 331, and descend smoothly. At the same time, under the action of the first return spring 332, the opening and closing unit plate 331 is closed again, thereby realizing the opening and closing descending action of the opening and closing unit plate 331, which plays a braking process. In order to improve the braking effect, this embodiment has rubber brake pads on the corresponding surfaces of the opening and closing unit plate 331 and the frame column 2.

[0064] like Fig.14 In the structure shown, in this embodiment, a rotating seat 522 is provided on the rotating disk 52, and the support plate 51 is installed on the rotating seat 522 in a flippable manner; a T-shaped vertical plate 53 is installed above the rotating seat 522, and an electric cylinder 54 for providing a flipping power source is installed between the T-shaped vertical plate 53 and the support plate 51, and the lifting angle can be adjusted and the lifting force can be maintained through the electric cylinder 54. The rotating disk 52 is provided with a socket 521 that fits with the frame column 2, and the support plate 51 is provided with an anti-blocking notch 511 for avoiding obstruction and restriction during flipping.

[0065] like Figure 1The structure shown is a construction device for crossing overhead power lines in this embodiment. Its working principle is as follows: in order to lift the crossing power line 1 arranged above, four construction devices can be arranged around the lower cable in this embodiment. The lifting and moving part 4 equipped with the clamping part 3 and the line supporting part 5 is pre-mounted on the frame column 2. Three wheels 43 are arranged in this embodiment to be installed at the position of the moving groove 201. The driving motor power supply of this embodiment adopts a battery, which is installed under the moving cylinder 41. After closing, it is covered by the lower installation cover 31. The perspective is not shown in the figure for special explanation; the driving motor drives the active driving gear 46 to rotate, and then the gear ring 44, the first gear 424, the first bevel gear 425, the second bevel gear 426 and the second gear 429 are driven to rotate synchronously. The second gear 429 drives the reversing gear 428 to rotate, so that the wheel body 43 keeps the same rotation direction and climbs upward;

[0066] During the climbing process, the brake unit 45 will not brake, but only keep the three opening and closing unit plates 331 in a closed trend under the action of the first return spring 332, and can move along the frame column 2 without being affected by the anti-falling slot 202. If the weight of the upper support is heavy and slides downward, it will get stuck in the anti-falling slot 202;

[0067] During the downward movement, the ratchet 452 pushes the movable pawl 453, so that the pawl 453 retreats along the movable slide groove 4511. In this embodiment, a spring is installed in the movable slide groove 4511 to push the hexagonal shaft of the pawl 453, so that the pawl 453 can maintain a stable periodic reset action; this process squeezes the second reset spring 454, and the second reset spring 454 drives the push rod 455 to move downward, and the push rod 455 presses down to push the extrusion block 32, and the extrusion block 32 is as shown in FIG. Figure 6 The structure shown adopts a truncated cone-like structure that matches the three opening and closing unit plates 331, which can open the opening and closing unit plates 331 so that the anti-falling slot 202 will not be stuck in the descending process; at the same time, this process will cause the ratchet 452 teeth to produce periodic reciprocating motion, which is manifested as the three opening and closing unit plates 331 continuously opening and closing during the downward movement process, thereby obtaining a braking friction force for the downward movement and avoiding the problem of stalling or falling during descent; the device has a stable lifting process and can drive the line supporting part 5 to obtain a stable lifting structure.

[0068] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0069] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0070] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
