Description

Technical Field

[0001] The utility model relates to the technical field of electric power engineering, and particularly relates to a wire clamp for electric power engineering. Background Art

[0002] Electric power engineering is the engineering related to the production, transmission, and distribution of electric energy, including the engineering of applying electricity as power and energy in multiple fields. In electric power engineering, wire clamps are often used. A wire clamp is an iron or aluminum metal accessory that can be fixed on a wire, and most of them need to bear a large tensile force during operation; since the wire will be affected by the external temperature, it will cause the wire to sag excessively or break due to being too tight. Therefore, people need to adjust the tightness of the wire.

[0003] Chinese patent document CN221009766U discloses a wire clamp for electric power engineering, which includes a wire winding box, a wire clamping plate, a steel wire rope, a reversing pulley, a wire winding shaft, a motor, a wire winding cylinder, and a coil spring; there are two steel wire ropes on the wire clamping plate of this utility model. When the wire sags excessively, the motor will start, so that the wire winding shaft winds up the steel wire rope, reducing the gap between the wire winding box and the wire clamping plate, and thus playing a role in straightening the wire; when the wire is too tight, the motor rotates in reverse, so that the wire winding shaft releases the steel wire rope, increasing the gap between the wire winding box and the wire clamping plate, and thus playing a role in relaxing the wire, preventing the wire from breaking due to being too tight; therefore, this utility model eliminates the phenomenon of excessive sag or breakage due to being too tight of the wire through the combination of the motor and the steel wire rope, and at the same time replaces the manual adjustment process, reducing the risk coefficient of the operator.

[0004] The following problems exist in the prior art:

[0005] The wire clamp uses a wire winding cylinder to wind the steel wire rope and the wire, but it is not provided with a guiding component, resulting in the steel wire rope and the wire piling up at one place on the wire winding cylinder, making it difficult to lay flat on the wire winding cylinder, and thus reducing the wire winding capacity of the wire winding cylinder.

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0024] As Figure 1 shown, a wire clamp for power engineering includes a protective housing 1. Mounting plates 2 are fixedly connected to the positions near the rear sides of the left and right sides of the protective housing 1. Three laterally distributed outlet pipes 3 are fixedly connected to the position near the bottom of the front side of the protective housing 1. Converging mechanisms 4 are rotatably connected to the left and right sides inside the protective housing 1. Conducting wires 5 are wound and connected to the positions near the bottom of the outer sides of the converging mechanisms 4. Two symmetrically distributed steel wire ropes 6 are wound and connected to the positions near the upper sides of the outer sides of the converging mechanisms 4.

[0025] It should be noted that the conducting wires 5 and the steel wire ropes 6 are connected together by the same clamping plates and anti-twisting blocks as in the reference case, so that the steel wire ropes 6 support the conducting wires 5.

[0026] As Figure 2 、 Figure 3 and Figure 5 shown, the converging mechanism 4 includes a motor 41. The lower side of the motor 41 is fixedly connected to the position near the upper right rear side of the protective housing 1. The output end of the motor 41 is fixedly connected to a worm 42. First lead screws 43 are rotatably connected to the positions near the upper rear sides of the left and right sides inside the protective housing 1. A worm gear 44 is fixedly connected to the outer wall near the right end of the first lead screw 43. The rear side of the worm gear 44 is meshed and connected to the front side of the worm 42.

[0027] It should be noted that the motor 41 drives the worm 42 to rotate. When the worm 42 rotates, it drives the worm gear 44 to rotate. When the worm gear 44 rotates, it drives the first lead screw 43 to rotate. Due to the self-locking property between the worm 42 and the worm gear 44, only the worm 42 can drive the worm gear 44 to rotate, but the worm gear 44 cannot drive the worm 42 to rotate.

[0028] As Figure 3 、 Figure 5As shown in the figure, the left and right sides of the inner side of the protective housing 1 near the lower rear side are rotatably connected with a second lead screw 45. The lower end of the worm 42 is fixedly connected with a first bevel gear 46. The outer wall of the second lead screw 45 near the right end is fixedly connected with a second bevel gear 47. The upper side of the second bevel gear 47 is meshed and connected with the left side of the first bevel gear 46.

[0029] It should be noted that when the worm 42 rotates, it drives the first bevel gear 46 to rotate. When the first bevel gear 46 rotates, it drives the second bevel gear 47 to rotate. When the second bevel gear 47 rotates, it drives the second lead screw 45 to rotate.

[0030] As Figures 2 - 5 shown in the figure, two rotating rods 48 distributed up and down are rotatably connected to the left and right sides of the inner side of the protective housing 1 near the rear side. The outer walls of the two rotating rods 48 near the right side, the outer wall of the first lead screw 43 near the right side, and the outer wall of the second lead screw 45 near the right side are all fixedly connected with spur gears 416. The mutually adjacent sides of the front and rear two spur gears 416 on the same side are meshed and connected together. The outer walls of the first lead screw 43 and the second lead screw 45 are both threadedly connected with moving seats 49. And two moving seats 49 are symmetrically distributed left and right on the first lead screw 43. The front sides of the three moving seats 49 are all rotatably connected with winding sleeves 410. The inner sides of the winding sleeves 410 are movably sleeved on the outer sides of the rotating rods 48. The outer side of the wire 5 is wound and connected to the outer side of the lower winding sleeve 410. The outer side of the steel wire rope 6 is wound and connected to the outer side of the upper winding sleeve 410.

[0031] It should be noted that both the first lead screw 43 and the second lead screw 45 are reciprocating lead screws. There are two threads connected end to end on the first lead screw 43. There are two threads connected end to end on each of the left and right sides of the second lead screw 45. So when the first lead screw 43 and the second lead screw 45 rotate, the moving seat 49 makes a reciprocating motion in the left and right directions.

[0032] As Figures 2 - 4 shown in the figure, the left and right sides of the inner side of the protective housing 1 near the lower front side are rotatably connected with a first guide roller 411. The left and right sides of the front surface of the inner side of the protective housing 1 near the upper side are fixedly connected with two electromagnetic telescopic rods 414 distributed symmetrically left and right. The rear ends of the two electromagnetic telescopic rods 414 are both fixedly connected with connecting plates 413. The mutually adjacent sides of the connecting plates 413 are rotatably connected with two second guide rollers 412 distributed symmetrically up and down. The lower side of the wire 5 is lapped on the upper side of the lower second guide roller 412. The lower side of the steel wire rope 6 is lapped on the upper side of the upper second guide roller 412. The upper sides of the steel wire rope 6 and the wire 5 are lapped on the lower side of the first guide roller 411.

[0033] It should be noted that the electromagnetic telescopic rod 414 can control its own length, thereby driving the connecting plate 413 to move in the front-back direction. The electromagnetic telescopic rod 414 is inclined backward and downward, causing the connecting plate 413 to move slightly upward when moving forward.

[0034] As Figure 2 , Figure 4 shown, on the side where the two connecting plates 413 are away from each other, card slots 415 are provided. The inclined platforms on the left and right inner sides of the protective housing 1 are slidably connected to the inner sides of the card slots 415.

[0035] It should be noted that the functions of the card slot 415 and the inclined platform cause the polarity of the connecting plate 413, and at the same time make the connecting plate 413 more stable when moving.

[0036] The working principle of the present utility model: First, the motor 41 drives the worm 42 to rotate. When the worm 42 rotates, it drives the worm gear 44 to rotate. When the worm gear 44 rotates, it drives the first lead screw 43 to rotate. Due to the self-locking property between the worm 42 and the worm gear 44, only the worm 42 can drive the worm gear 44 to rotate, but the worm gear 44 cannot drive the worm 42 to rotate. When the worm 42 rotates, it drives the first bevel gear 46 to rotate. When the first bevel gear 46 rotates, it drives the second bevel gear 47 to rotate. When the second bevel gear 47 rotates, it drives the second lead screw 45 to rotate. Both the first lead screw 43 and the second lead screw 45 are reciprocating lead screws. There are two threads connected end to end on the first lead screw 43, and there are two threads connected end to end on each of the left and right sides of the second lead screw 45. Therefore, when the first lead screw 43 and the second lead screw 45 rotate, the moving seat 49 performs a reciprocating movement in the left-right direction. By driving the first lead screw 43 and the second lead screw 45 to rotate through the motor 41, the moving seat 49 performs a reciprocating movement left and right, so that the steel wire rope 6 and the wire 5 are evenly wound on the winding sleeve 410, improving the capacity of the winding sleeve 410 and preventing the wire from accumulating in one place, thus affecting the service life of the wire. Finally, the electromagnetic telescopic rod 414 can control its own length, thereby driving the connecting plate 413 to move in the front-back direction. The electromagnetic telescopic rod 414 is inclined backward and downward, causing the connecting plate 413 to move slightly upward when moving forward. The functions of the card slot 415 and the inclined platform cause the polarity of the connecting plate 413, and at the same time make the connecting plate 413 more stable when moving. By quickly driving the second guide roller 412 to move through the electromagnetic telescopic rod 414, the tightness of the wire 5 and the steel wire rope 6 within a certain range can be quickly adjusted, avoiding the problem of frequent adjustment caused by only using the method of winding the wire. For example, in the case of high-frequency temperature changes, repeatedly using the winding method increases the wear of the components. However, by directly moving the second guide roller 412, it is convenient to adjust, reduce component loss, and reduce maintenance costs.
