Description

Technical Field

[0001] This utility model relates to the technical field of wedge-shaped wire clamps, specifically a high-stability wedge-shaped wire clamp with a shock-absorbing device. Background Technology

[0002] Fittings are iron or aluminum metal accessories widely used in power transmission lines. Most fittings need to withstand significant tensile force during operation, and some must simultaneously ensure good electrical contact. Furthermore, with the widespread use of electrical and electronic equipment, the demand for electricity is increasing. To ensure economic efficiency and quality of life, power maintenance is increasingly moving towards uninterrupted power supply (UDS) work. DAS, also known as live-line work, involves power maintenance personnel directly contacting the power lines and using specialized equipment to perform operations on the lines. To ensure the safety, efficiency, economy, and speed of DAS work, wire clamp fittings are required during the process.

[0003] Existing wedge clamps are used for passing wires, but they do not have relevant protective and shock-absorbing structures inside. When the wires are at a height, they are affected by external factors such as wind and sway. When this happens, the wires will come into contact with the protruding side of the clamp, which may lead to wear and breakage of the wires. Utility Model Content

[0004] The purpose of this invention is to provide a highly stable wedge-shaped wire clamp with a shock-absorbing device that provides good shock absorption and protects the sides of the wire from damage.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The device includes a wedge-shaped fitting, which has a large opening at one end and a small opening at the other. A rubber sleeve is slidably inserted into the wedge-shaped fitting. There are two rubber sleeves, which are symmetrically arranged. Each rubber sleeve has a fixing plate fixed near both ends. The two fixing plates of one rubber sleeve are flush with the ends of the rubber sleeve, while the two fixing plates of the other rubber sleeve are arranged near the middle of the rubber sleeve. The two opposing fixing plates on different rubber sleeves are arranged adjacent to each other. The rubber sleeve has an elastic element on its side.

[0007] Furthermore, an arc-shaped rubber plate is screwed to the end of the rubber sleeve facing the small opening of the wedge-shaped fitting. An extension plate is integrally fixed to the arc-shaped rubber plate away from the end of the rubber sleeve. The extension plate is wedge-shaped and enclosed. By adopting the above technical solution, an enclosed extension plate is set at the protruding end of the wire. During the wire's swaying process, it contacts the extension plate, covering and supporting the wire, reducing the amplitude of wire swaying, and improving the stability of the wire.

[0008] Furthermore, the rubber sleeve has a groove near the inner wall of the wedge-shaped fitting, and several grooves are evenly spaced along the length of the rubber sleeve.

[0009] Furthermore, the elastic element includes a fixed post fixed to the bottom of the groove. Two fixed posts are symmetrically arranged inside each groove. A sliding post is slidably connected inside each fixed post. An abutment plate is fixed to the end of the sliding post away from the fixed post.

[0010] Furthermore, the contact plate has wedge-shaped surfaces at both ends.

[0011] The above technical solution facilitates the entry of the contact plate into the wedge-shaped fitting without affecting the pulling of the wire along the axial direction of the wedge-shaped fitting.

[0012] Furthermore, a spring is fixed inside the fixed column, and the end of the spring away from the fixed column is fixed to the end face of the sliding column.

[0013] Using the above technical solution, after the wire is pulled, the rubber sleeve is squeezed, causing the contact plate to drive the sliding column to slide along the inner wall of the fixed column. At the same time, it contacts the spring, and the spring is compressed. The friction of the sliding column counteracts the tension of the external wire, thus achieving a shock absorption effect.

[0014] In summary, the beneficial technical effects of this utility model are as follows:

[0015] 1. An extension plate is used. An enclosing extension plate is set at the protruding end of the wire. When the wire swings, it comes into contact with the extension plate, covering and supporting the wire, reducing the amplitude of wire swing and improving the stability of the wire.

[0016] 2. An abutment plate is used. When the wire is pulled, it squeezes the rubber sleeve, causing the abutment plate to drive the sliding column to slide along the inner wall of the fixed column. At the same time, it abuts the spring, and the spring is compressed. The friction of the sliding column counteracts the tension of the external wire, achieving a shock absorption effect.

[0017] 3. A wedge-shaped surface is adopted, which facilitates the insertion of the contact plate into the wedge-shaped fitting and does not affect the pulling of the wire along the axial direction of the wedge-shaped fitting. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[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 1-4 The present invention provides a technical solution comprising: a wedge-shaped fitting 1, one end of which is a large opening and the other end is a small opening; a rubber sleeve 2 is slidably inserted inside the wedge-shaped fitting 1; two rubber sleeves 2 are provided and symmetrically arranged; each rubber sleeve 2 is fixed with a fixing plate 3 near both ends; the two fixing plates 3 of one rubber sleeve 2 are flush with the ends of the rubber sleeve 2, and the two fixing plates 3 of the other rubber sleeve 2 are arranged near the middle of the rubber sleeve 2; the two opposing fixing plates 3 on different rubber sleeves 2 are arranged adjacent to each other; and an elastic element is provided on the side of the rubber sleeve 2.

[0027] The end of the rubber sleeve 2 facing the small end of the wedge-shaped hardware 1 is fixed with an arc-shaped rubber plate 4. The end of the arc-shaped rubber plate 4 away from the rubber sleeve 2 is integrally fixed with an extension plate 5. The extension plate 5 is set in a wedge-shaped enclosure. The small end of the wedge-shaped hardware 1 is generally the end of the wire protrusion. The enclosure-shaped extension plate 5 is set at the end of the wire protrusion. During the wire swaying, it comes into contact with the extension plate 5, covering and supporting the wire, reducing the amplitude of the wire swaying and improving the stability of the wire.

[0028] In this embodiment, a rubber sleeve 2 is provided inside the wedge-shaped hardware 1. The two rubber sleeves 2 are symmetrically arranged and are simultaneously abutted by a fixing plate 3 during pulling. The wire extends out between the two rubber sleeves 2. A groove 6 is provided on the side of the rubber sleeve 2 near the inner wall of the wedge-shaped hardware 1. Several grooves 6 are provided at equal intervals along the length direction of the rubber sleeve 2.

[0029] The elastic element includes a fixed post 7 fixed to the bottom of the groove 6. Two fixed posts 7 are symmetrically arranged inside each groove 6. A sliding post 8 is slidably connected inside each fixed post 7. An abutment plate 9 is fixed to the end of the sliding post 8 away from the fixed post 7.

[0030] Furthermore, at the position where the wire is located between the two rubber sleeves 2, the wire can be fixed by the contact between the rubber sleeves 2. At the same time, a sliding contact plate 9 is provided on the side of the rubber sleeve 2. The contact plate 9 extends beyond the groove 6 in the free state. At the same time, wedge-shaped surfaces are provided at both ends of the contact plate 9. When the rubber sleeve 2 slides along the inside of the wedge-shaped hardware 1, it can contact the inner wall of the wire clamp hardware through the wedge-shaped surface 11 on the side of the contact plate 9, so that the rubber sleeve 2 can slide freely.

[0031] An elastic structure is provided between the contact plate 9 and the groove 6 at the position inside the wire clamp hardware. A spring 10 is fixed inside the fixed post 7, and the end of the spring 10 away from the fixed post 7 is fixed to the end face of the sliding post 8. When the wire is pulled, it squeezes the rubber sleeve 2, causing the contact plate 9 to drive the sliding post 8 to slide along the inner wall of the fixed post 7, while simultaneously contacting the spring 10. The spring 10 is compressed, and the friction of the sliding post 8 counteracts the pulling force of the external wire, achieving a shock absorption effect.

[0032] The working principle of this utility model is as follows: Two rubber sleeves 2 are provided for the power supply line to pass through. The sides of the rubber sleeves 2 are provided with elastically sliding contact plates 9. When the wire is pulled, the rubber sleeves 2 are squeezed, so that the contact plates 9 drive the sliding column 8 to slide along the inner wall of the fixed column 7. At the same time, they contact the spring 10, and the spring 10 is compressed. The friction of the sliding column 8 counteracts the tension of the external wire, achieving a shock absorption effect. At the same time, a surrounding extension plate 5 is provided at the protruding end of the wire. During the wire swaying process, it contacts the extension plate 5, covering and supporting the wire, reducing the amplitude of wire swaying, and improving the stability of the wire.
