Description

[0001] The present invention relates to the technical field of power transmission and transformation circuits, and in particular to a power transmission and transformation line interval maintaining device. Background Art

[0002] The process of electric current transmission requires multiple transformations, so it is called power transmission and transformation. In the process of laying power transmission and transformation lines, cable trays are often used to erect and fix the lines. Currently, most cable trays on the market are made of welded steel structures. This design makes it impossible to flexibly adjust the cable trays. Due to the lack of adjustment function, the existing cable trays cannot meet the demand for adjusting the line spacing size according to actual needs during line laying.

[0003] After consulting the relevant patent document CN117578322A, it is found that there are still some problems with the existing transmission and transformation line interval maintenance device. The optimization scheme currently on the market is mainly: "By pushing the No. 2 top frame and the No. 1 top frame, the No. 2 adjustment frame and the No. 1 adjustment frame can be driven to move to push the No. 2 adjustment slide and the No. 1 adjustment slide, so that the two No. 2 adjustment slides and the two No. 1 adjustment slides can slide on the line supporting cross frame to move to both sides, thereby driving the movement of multiple lines, so that the multiple lines are gradually dispersed, so as to adjust the intervals between the multiple lines to meet the line layout requirements. However, after the device adjusts the wire spacing, if there is strong wind, the wires will shake on the device. On the one hand, the shaking can easily cause the wires to collide with each other, resulting in short circuit or damage. On the other hand, usually at the supporting point, the wires will sag symmetrically on both sides of the supporting point due to the gravity of the wires themselves. In addition, the violent shaking caused by strong winds can easily cause friction between the supporting points, thereby causing damage to the wires. The wires are more likely to be worn off over a long period of time. In view of the above problems, a transmission and transformation line spacing maintenance device is proposed.

The fixed rod 141 and the second connecting rod 146 and the rectangular slider 7 are all slidingly connected. The end of the fixed rod 141 away from the end fixedly connected to the cross bar 2 slides with the clamping plate 610, the first driving gear 142 is rotationally connected to the first connecting rod 609, and the first driven gear 143 is rotationally connected to the fixed plate 147 on the side away from the second driven gear 144, and the upper end of the fixed plate 147 is fixedly connected to the outer wall of the first connecting rod 609.

[0029] The driving mechanism 16 includes a third driven gear 161, which is meshed with the second driving gear 15. The upper surface of the third driven gear 161 is fixedly connected with a handle 162. The inner part of the third driven gear 161 is rotatably connected with a positioning shaft 163. The bottom of the positioning shaft 163 is fixedly connected with an inner ring 164. The bottom of the inner ring 164 is fixedly connected with a chassis 166. The upper surface of the chassis 166 close to the circumferential side is fixedly connected with an outer ring 165. The outer ring 165 and the inner ring 164 are spaced a certain distance apart.

[0030] An anti-slip block 167 is slidably connected inside the chassis 166, and a connecting bolt 168 is fixedly connected to the upper surface of the anti-slip block 167. The top of the connecting bolt 168 is fixedly connected to the lower surface of the third driven gear 161, and a fastening nut 169 is rotatably connected to the surface of the connecting bolt 168.

[0031] The working principle of a power transmission and transformation line interval maintenance device in the embodiment of the present application is as follows: when adjusting the interval, first loosen the fastening nut 169, then hold the handle 162, and rotate the third driven gear 161 through the handle 162, so that the third driven gear 161 drives the connecting bolt 168 to slide inside the chassis 166, and at the same time, the rotation of the third driven gear 161 will synchronously drive the second driving gear 15 to rotate, so that the second driving gear 15 drives the positioning block 4 to rotate, so that the slip ring 602 is The top end of the rotating shaft 5 moves upward, so that the slip ring 602 drives the roller 603 to move upward inside the supporting box 604. Under the action of the roller 603, the roller 603 slides the arc block 607 outward along the inside of the horizontal slide groove 605, so that the arc block 607 pushes the first connecting rod 609 to move. When the first connecting rod 609 moves, the first driving gear 142 rotates on the surface of the fixed rod 141. At the same time, the first driven gear 143 and the second driven gear 144 are driven by the first driving gear 142 to reverse. The second driving gear 15 is meshed with the second driven gear 144 above it, so that the second driven gear 144 drives the moving rod 145 to move in the same direction. Because the second driven gear 144 is larger than the first driving gear 142, the moving rod 145 moves at a speed greater than the moving speed of the first connecting rod 609, so that the distance between the adjusting bolt 11 at the outermost end of the upper surface of the cross bar 2 and the adjusting bolt 11 beside it gradually increases, so as to adjust the spacing of the wires and cables. When adjusted to a suitable position, the third driven gear 161 is stopped from rotating, and the fastening nut 169 is tightened to complete the fixation of the third driven gear 161, so that the second driving gear 15 and the positioning block 4 both stop rotating, so that the distance between the adjusting bolts 11 on the upper surface of the cross bar 2 can be kept fixed. Finally, according to actual needs, by screwing the torsion cap 134, the first belt 135 and the second belt 136 are driven to transmit in the same direction, so that the two sets of adjusting bolts 11 rotate synchronously, and the spacing adjustment between the fixed structures 10 is completed.

[0032] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention.
