Description

Technical Field

[0001] This utility model relates to the field of iron accessories technology, specifically an iron accessory for the installation of power grid transmission lines. Background Technology

[0002] Iron fittings generally refer to the iron parts on concrete poles and their wiring, such as various clamps, bolts, crossbeams, crossbars, tie rods, and wire rods. In practical applications, iron fittings can be used to tighten cables and prevent them from overlapping or collapsing.

[0003] However, the current iron accessories for wires have the following problems: (1) When there are too many cables on the same horizontal line, clamps are needed to separate the cables into multiple groups and tighten them. If there are too many cables in each group, resulting in a large diameter, and the spacing of the clamps cannot be adjusted, the adjacent cables will come into contact, which is not conducive to separating the cables; (2) Due to the different positions (such as height) of the cables, after the clamps connected to the pole are fixed, the height of the clamps cannot be adjusted, so they cannot be adapted to cables of different heights. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an iron accessory for power grid transmission line installation, thereby solving the problems mentioned in the background section.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An iron accessory for installing power grid transmission lines includes a mounting base, a groove on one side of the mounting base, a first mounting plate slidably connected in the groove, and a driving mechanism on the mounting base for driving the first mounting plate to slide in the groove; a second mounting plate is hinged to the end of the first mounting plate away from the mounting base via a hinge mechanism, and the first and second mounting plates are fixed by a locking mechanism; both the first and second mounting plates are provided with sliding holes, and clamps are slidably disposed in the two sliding holes.

[0007] Preferably, the driving mechanism includes a lead screw and a handle. The lead screw is rotatably connected in a slide groove, one end of the lead screw protrudes through a retainer, and the protruding end is connected to a handle. One end of the first mounting plate is threadedly connected to the lead screw.

[0008] The above technical solution involves rotating the handle to drive the lead screw to rotate, which in turn causes the first mounting plate to move along the lead screw within the slide groove, thereby adjusting the position of the first mounting plate.

[0009] Preferably, the hinge mechanism includes two bearing plates connected to one end of the first mounting plate, a rotating block connected to one end of the second mounting plate, a shaft fixedly connected to the two bearing plates, and limiting plates connected to both ends of the shaft. The rotating block is rotatably connected to the shaft, and the two limiting plates are pressed tightly against their respective bearing plates.

[0010] The above technical solution allows for the fixing of cables in different directions using clamps on the second mounting plate and the first mounting plate by adjusting the angle between the two plates.

[0011] Preferably, the outer end faces of both bearing plates are provided with first slots, the first slots are on the same straight line as the axis of the shaft, and the second mounting plate is provided with second slots on both sides near the rotating block. The first slots are provided with internal splines, and the inner walls of the second slots are provided with internal threads. The locking mechanism includes a J-shaped positioning rod, a first nut rotatably connected to one end of the positioning rod through a rotary bearing, and a screw fixedly connected to the first nut. There are two positioning rods, located on both sides of the hinge mechanism. The end of the positioning rod away from the screw is provided with an external spline and splined into the first slot. The screw is threaded into the second slot on the same side. The end of the positioning rod away from the screw is threaded with a second nut. Tightening the second nut can press it tightly against the bearing plate.

[0012] In the above technical solution, after the second mounting plate is adjusted to the required angle, the screw at one end of the positioning rod is threaded into the second slot. Then, the positioning rod is rotated so that the external spline at the other end of the positioning rod is aligned with the internal spline in the first slot. Then, the first nut is tightened so that the screw continues to move into the second slot until the spline of the positioning rod is connected to the first slot. This can keep the second mounting plate stable and prevent it from rotating.

[0013] Preferably, the clamp includes a base, a sliding rod connected to the lower end of the base, and an arc-shaped clamping plate hinged to the upper end of the base. The upper part of the base is provided with an arc-shaped groove that cooperates with the clamping plate. The end of the clamping plate away from the hinge is connected to the base by bolts. The sliding rod is slidably connected in the sliding hole, and the lower end of the sliding rod is threaded with a third nut.

[0014] The above technical solution allows the position of the slide rod to be adjusted by loosening the third nut, thereby adjusting the position of the clamp, and the clamp can be fixed in the required position by tightening the third nut.

[0015] Preferably, the card holder has an arc-shaped groove on the side away from the slide groove, and a U-shaped card rod is inserted into the side of the card holder near the groove. The card rod passes through the card holder and is threaded with a fourth nut at the end of the passage.

[0016] The above technical solution uses a clamp to fix the mounting bracket at the desired position on the utility pole.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) The cables can be divided into multiple groups by the clamps on the first and second mounting plates, and the spacing of the clamps is adjustable, thereby preventing adjacent cables from contacting each other.

[0019] (2) When the height of the cable or the cable is not on the same plane, the height of the first mounting plate and the second mounting plate can be adjusted, or the second mounting plate can be rotated to adjust the direction of the clamps on it, so as to tighten the cables in different directions or heights.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 An iron accessory for installing power grid transmission lines includes a mounting base 1. A groove 2 is provided on one side of the mounting base 1, and a first mounting plate 3 is slidably connected within the groove 2. The mounting base 1 is equipped with a driving mechanism for driving the first mounting plate 3 to slide within the groove 2. Specifically, the driving mechanism includes a lead screw 6 and a handle 7. The lead screw 6 is rotatably connected within the groove 2, with one end of the lead screw 6 extending from the mounting base 1 and connected to the handle 7. One end of the first mounting plate 3 is threadedly connected to the lead screw 6. Rotating the handle 7 causes the lead screw 6 to rotate, thereby moving the first mounting plate 3 along the lead screw 6 within the groove 2 to adjust the position of the first mounting plate 3.

[0027] like Figure 2 , Figure 3 As shown, the end of the first mounting plate 3 furthest from the card seat is hinged to the second mounting plate 4 via a hinge mechanism, and the first mounting plate 3 and the second mounting plate 4 are fixed by a locking mechanism. Specifically, the hinge mechanism includes two bearing plates 8 connected to one end of the first mounting plate, a rotating block 9 connected to one end of the second mounting plate, a shaft 10 fixedly connected to the two bearing plates, and limiting plates 11 connected to both ends of the shaft. The rotating block 9 is rotatably connected to the shaft 10, and the two limiting plates 11 are pressed tightly against their respective bearing plates 8. By rotating the second mounting plate 4, the rotating block 9 can rotate on the shaft 10 to adjust the second mounting plate 4 to the required angle. Both bearing plates 8 have a first slot 12 on their outer end faces. The first slot 12 and the axis of the shaft 10 are on the same straight line. The second mounting plate 4 has a second slot 13 on both sides near the rotating block. The first slot 12 has an internal spline, and the inner wall of the second slot 13 has an internal thread. The locking mechanism includes a J-shaped positioning rod 14, a first nut 16 rotatably connected to one end of the positioning rod via a rotary bearing 15, and a screw 17 fixedly connected to the first nut. There are two positioning rods 14, located on both sides of the hinge mechanism. The end of the positioning rod 14 away from the screw has an external spline and is splined into the first slot 12. The screw 17 is threaded into the second slot 13 on the same side. The end of the positioning rod 14 away from the screw is threaded with a second nut 18. Tightening the second nut 18 can press it tightly onto the bearing plate 8. Figure 3 As shown, after the second mounting plate 4 is adjusted to the required angle, the screw 17 at one end of the positioning rod 14 is threaded into the second slot 13. Then, the positioning rod 14 is rotated so that the external spline at the other end of the positioning rod 14 is aligned with the internal spline in the first slot 12. Then, the first nut 16 is tightened so that the screw 17 continues to move into the second slot 13 until the spline of the positioning rod 14 is connected into the first slot 12. This will keep the second mounting plate 4 stable and prevent it from rotating.

[0028] For example, 1. Figure 4 As shown, both the first mounting plate 3 and the second mounting plate 4 are provided with sliding holes 19, and clamps 5 are slidably disposed within the two sliding holes 19. Specifically, the clamp 5 includes a base 501, a sliding rod 502 connected to the lower end of the base, and an arc-shaped clamping plate 503 hinged to one end of the upper part of the base. The upper part of the base 501 is provided with an arc-shaped groove 504 that mates with the clamping plate. The end of the clamping plate 503 away from the hinge is bolted to the base 501. The sliding rod 502 is slidably connected within the sliding hole 19, and the lower end of the sliding rod 502 is threadedly connected to a third nut 505. Loosening the third nut 505 can adjust the position of the sliding rod 502, thereby adjusting the position of the clamp 5. Tightening the third nut 505 can fix the clamp 5 in the desired position.

[0029] The working principle of this embodiment is as follows: Cables can be divided into multiple groups using clamps 5 on the first mounting plate 3 and the second mounting plate 4, and the spacing of the clamps 5 is adjustable, thereby preventing adjacent cables from contacting each other. The height of the first mounting plate 3 and the second mounting plate 4 can also be adjusted via a drive mechanism according to the height of the cables. Furthermore, the direction of the clamps on the second mounting plate 4 can be adjusted by rotating it according to the direction or angle of the cables, thereby tightening cables in different directions or at different angles.

[0030] Example 2

[0031] The difference between this embodiment and Embodiment 1 is that the card holder 1 has an arc-shaped groove 20 on the side away from the slide groove, and a U-shaped locking rod 21 is inserted into the side of the card holder 1 near the groove. The locking rod 21 passes through the card holder and is threaded to a fourth nut 22 at the end of the rod. The locking rod 21 can fix the card holder 1 at the desired position on the utility pole.
