Description

Technical Field

[0001] The utility model relates to the technical field of power transmission, and more specifically, to a power grid support frame. Background Art

[0002] Electric energy refers to the ability to use electricity in various forms to do work (i.e., generate energy). Electric energy is an economical, practical, clean, and easy-to-control and convert form of energy. It is also a special product provided by the power sector to electricity users, with the quality guaranteed by the three parties of generation, supply, and use. It also has several product characteristics, such as being measurable, predictable, guaranteed, or improved. Electric energy is widely used in various fields such as power, lighting, chemistry, textiles, communications, and broadcasting. It is the main driving force for scientific and technological development and economic leap. At present, the transmission of electric energy needs to rely on wires, so support frames need to be erected to support the wires.

[0003] Most of the existing support frames are made of iron products welded or riveted. After completion, the support direction of the support frame is fixed. It takes a lot of energy and time to change the direction of the support frame during the installation process. In addition, when the support frame encounters a corner where the wires are laid, another device needs to be used for orientation and fixation. This not only increases the cost investment, but also is inconvenient to use. In addition, due to gravity and the influence of external factors, the support frame will move downward for a certain distance, resulting in inconsistent falling distances of the power grid on each section of the bracket, which can easily make the power grid in some distance sections fall too far and pose a safety hazard.

[0032] See also Figure 1-9 ,The utility model provides a technical solution:

[0033] A power grid support frame includes a power pole 1 and a support frame, which is fixed to the top of the power pole 1. The support frame includes a base plate 2, a support plate 3, two bearing plates 4, a bidirectional motor 5, two support structures 6, a constraint structure 7 and a steering structure 9. The base plate 2 is fixed to the top of the power pole 1, the support plate 3 is located above the base plate 2, the two bearing plates 4 are located on both sides of the top of the support plate 3, the bidirectional motor 5 is installed at the bottom end of the support plate 3, one end of the bidirectional motor 5 is fixed to the constraint structure 7, and the other end of the bidirectional motor 5 is fixed to the steering structure 9. The support structure 6 is located on the top of the bearing plate 4, which solves the problems of the support frame being unable to rotate, inconvenient to turn corners, and falling.

[0034] Specifically, the supporting structure 6 includes a vertical plate 61, a clamping plate 62, a wire trough 63, a fixing rod 64 and a reinforcing plate 65. The bottom end of the vertical plate 61 is fixedly connected to the top of the supporting plate 4. The wire trough 63 is opened inside the vertical plate 61 and the clamping plate 62. The top end of the fixing rod 64 is fixedly connected to the bottom end of the clamping plate 62. A protrusion is provided on the left side of the clamping plate 62. The interior of the vertical plate 61 is provided with a groove for the fixing rod 64 and the protrusion to cooperate. The fixing rod 64 and the protrusion are embedded in the groove and fixed by bolts and nuts, which can fix the position of the wires and prevent the wires from shaking.

[0035] Furthermore, the constraint structure 7 includes a gear 71, a belt 72, two second gears 73, two connecting rods 74, two brackets 75, two moving rings 76, a limit block 77 and a clamp 78. The output end of the top of the bidirectional motor 5 is fixedly connected to the bottom of a gear 71, the belt 72 is sleeved on the surface of a gear 71 and the two second gears 73, and a gear 71 is located between the two second gears 73, the bottom end of the connecting rod 74 is fixedly connected to the top of the second gear 73, the top of the connecting rod 74 is fixedly connected to the bottom of the bracket 75, the side of the bracket 75 away from the connecting rod 74 is fixedly connected to the inner side of the moving ring 76, the bottom end of the moving ring 76 is fixedly connected to the top of the limit block 77, and the end of the limit block 77 away from the moving ring 76 is embedded in the interior of the support plate 3, and the clamp 78 is fixedly connected to the top of the moving ring 76. The constraint structure 7 can drive the two clamps 78 to move synchronously, so that the clamping direction and angle of the clamp 78 are synchronized.

[0036] It is worth noting that the clamp 78 includes a vertical rod 781, a connecting shaft 782, a side plate 783, two side plates 784, a constraint groove and a fixed block 785. The bottom end of the vertical rod 781 is fixedly connected to the top of the movable ring 76. One end of the connecting shaft 782 is embedded in the vertical rod 781 and connected by a rotating shaft. The other end of the connecting shaft is connected to the side of the side plate 783 through the rotating shaft. The constraint groove is opened inside the one side plate 783 and the two side plates 784. The fixed block 785 is respectively fixed on the left side of the top and bottom of the one side plate 783 and on the right side of the top and bottom of the two side plates 784. The clamp 78 can assist in clamping the wires and enable the wires to pass through the wire groove 63 in a straight line.

[0037] It is worth noting that the two fixing blocks 785 at the top and the two fixing blocks 785 at the bottom are fixed by bolts, and the one side plate 783 and the two side plates 784 are in the shape of a semicircle. The semicircle can reduce the friction area with the wires and prevent the wires from turning at too small an angle to damage the protective skin or inner core.

[0038] In addition, the steering structure 9 includes a connecting frame 91, a connecting column 92 and a sliding ring 93. The output end of the bottom end of the bidirectional motor 5 is fixedly connected to the top of the connecting frame 91, the four corners of the connecting frame 91 are fixedly connected to the connecting column 92, one end of the connecting column 92 is fixedly connected to the support plate 3, and the other end of the connecting column 92 is fixedly connected to the top of the sliding ring 93. The end of the sliding ring 93 away from the connecting column 92 is embedded in the bottom plate 2, and a groove compatible with the sliding ring 93 is opened inside the bottom plate 2. The two output ends of the bidirectional motor 5 respectively drive the constraint structure 7 and the steering structure 9, which not only realizes the steering function of the support frame but also can realize auxiliary constraint of the wires.

[0039] It must be said that a plurality of balls 8 are arranged inside the base plate 2, and the plurality of balls 8 are concentrically distributed at the bottom of the sliding ring 93 with the center of the sliding ring 93, thereby reducing the friction when the sliding ring 93 rotates, reducing the load of the bidirectional motor 5, and increasing the service life of the bidirectional motor 5.

[0040] Working principle: When the wire needs to be turned during the laying process, the user embeds the wire into the constraint groove of one side plate 783, and then fixes the wire through the two side plates 784, the fixing block 785 and the bolts. Then the user starts the output end of the top of the bidirectional motor 5, and the output end of the top of the bidirectional motor 5 drives a gear 71 to rotate. The gear 71 drives two second gears 73 to rotate through the belt 72. The two gears 73 rotate the bracket 75 to move. The movement of the bracket 75 drives the moving ring 76 to move. The movement of the moving ring 76 drives the limit block 77 and the clamp 78 to move. The clamp 78 drives the wire to rotate. When the wire rotates to the appropriate angle, the user turns off the bidirectional motor 5, and then passes the other end of the wire through the wire groove 63, and then through the clamp The fixing rod 64 and the protruding edge of the plate 62 are embedded in the interior of the vertical plate 61, and then fixed with bolts to complete the installation. When the falling wires need to be tightened, the user starts the top output end of the bidirectional motor 5 again to move the two clamps 78 inward or outward to tighten the falling wires and close them. When the direction of the support frame needs to be rotated, the user starts the output end of the bottom end of the bidirectional motor 5. The output end of the bottom end of the bidirectional motor 5 drives the connecting frame 91 to move the rod. The movement of the connecting frame 91 drives the connecting column 92 to move. The movement of the connecting column 92 drives the sliding ring 93 and the support plate 3 to move. The support plate 3 drives the support frame to move as a whole. When the support frame reaches a suitable angle, the user turns off the bidirectional motor 5 to complete the operation.
