Description

Technical Field

[0001] This utility model relates to the field of metal clamps for overhead lines, and in particular to a locking rod clamp. Background Technology

[0002] A pole clamp is a metal clamp used in overhead power and communication lines to secure conductors. It uses bolts, wedges, or crimping to lock the conductor in place, preventing slippage or loosening. They are typically made of aluminum alloy or galvanized steel, offering both strength and corrosion resistance, and some designs include moisture-proof features.

[0003] Traditional cable clamps typically use an upward lifting method to clamp cables, which is unsuitable for cables of varying diameters. For large-diameter, heavy cables, the operation is time-consuming and labor-intensive, prone to cable slippage and insufficient clamping force, affecting operational safety and cable stability. Furthermore, the clamp itself lacks protective measures, leaving it completely exposed at high altitudes, making it susceptible to corrosion and wear on the insulation layer, as well as loosening, after prolonged exposure to wind and sun. Utility Model Content

[0004] The purpose of this utility model is to overcome the problems of existing technologies that use an upward lifting method, which are difficult to apply to large-diameter cables, are prone to cable slippage and insufficient clamping force, and have the clamp body exposed at high altitudes, making them susceptible to corrosion from wind and sun exposure over long periods of time. This utility model provides a locking rod clamp that is suitable for cables of different diameters, provides stable clamping force, and is equipped with an insulating protective layer to prevent corrosion and wear.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a locking rod cable clamp, comprising: a cable clamp body and a spiral clamping mechanism disposed on the cable clamp body, characterized in that: a cable groove is formed on the cable clamp body, the spiral clamping mechanism includes a movable clamping block slidably disposed on the cable clamp body along the length direction of the cable groove, and a screw threadedly connected to the cable clamp body for driving the movable clamping block to slide, the movable clamping block cooperating with the groove wall of the cable groove to clamp the cable, and a turning ring is provided at the end of the screw. By setting the operating position of the screw below the cable clamp body and providing a turning ring for inserting a lever, it is convenient for workers to operate the lever from the ground to turn it, thereby driving the movable clamping block to slide along the length direction of the cable groove and clamping the cable, improving work efficiency and avoiding the safety hazards that are prone to occur during high-altitude contact operations.

[0006] Furthermore, the groove wall of the wire trough is configured with a downward-facing first arc-shaped clamping surface, and the movable clamping block is located at the lower part of the wire trough and has an upward-facing second arc-shaped clamping surface. The screw is threadedly connected to the wire clamp body, and the top of the screw is rotatably connected to the movable clamping block to push the movable clamping block to slide along the length direction of the wire trough. The cable is placed on the second arc-shaped clamping surface of the movable clamping block, and the screw drives the movable clamping block and the cable to slide together along the length direction of the wire trough until the cable contacts and is clamped with the first arc-shaped clamping surface of the wire trough.

[0007] Furthermore, the groove wall of the cable tray is configured with an upward-facing first arc-shaped clamping surface. The movable clamping block is located at the top of the cable tray and has a downward-facing second arc-shaped clamping surface. The screw is rotatably mounted on the clamp body and threadedly connected to the movable clamping block. The clamp body has a sliding groove, and the rear end of the movable clamping block has a slider that slides along the sliding groove. A spring supports the clamp body and the movable clamping block. The spring is sleeved on the screw, with its lower end abutting the bottom of the sliding groove and its upper end abutting the lower surface of the slider. By using the spring, the clamp is always kept in an open state, making it easy to hang the cable on the clamp body. The cable is placed on the first arc-shaped clamping surface of the cable tray. The screw drives the movable clamping block to slide downward until the second arc-shaped clamping surface of the movable clamping block contacts and clamps the cable. The weight of the cable acts directly on the clamp body, and the movable clamping block is in a free state. Ground personnel can use a small force to drive the movable clamping block to clamp the cable, which is convenient for operation and avoids cable shaking during operation, thus improving safety.

[0008] Furthermore, the length direction of the wire groove forms an angle with the vertical direction, and the wire clamp body has an inclined surface along the length direction of the wire groove. The side of the movable clamp block is slidably connected to this inclined surface. The angle between the length direction of the wire groove and the vertical direction ranges from 10° to 45°.

[0009] Furthermore, the clamp body is fitted with an insulating shell, which includes a lower insulating shell fixedly fitted to the lower half of the clamp body and an upper insulating shell rotatably connected to the lower insulating shell. The upper insulating shell is provided with a pull ring for opening and closing the insulating shell.

[0010] Furthermore, the outer sides of the clamp body and the movable clamp block are covered with an insulating layer.

[0011] Furthermore, the surfaces of the cable groove and the movable clamp that contact the cable are provided with protruding ridges to increase the frictional force on the cable.

[0012] The beneficial effects of this utility model are: 1. This utility model utilizes a movable clamping block that engages with a groove in the clamp body. A screw drives the movable clamping block to clamp the cable. The movable clamping block can be positioned above or below the groove. When positioned above the groove, the cable's weight is supported by the groove (clamp body), making it suitable for large-diameter cables. When positioned below the groove, the cable's weight is supported by the movable clamping block and the screw, making it suitable for small-diameter cables. This design is simple in structure, highly stable, and suitable for cables of different diameters, avoiding problems such as cable slippage and insufficient clamping force, which affect operational safety and cable stability.

[0013] 2. This utility model sets the operating position of the screw below the clamp body and provides a screw ring for inserting the pull rod, which makes it convenient for workers to operate the pull rod on the ground to rotate and tighten the pull rod, thereby driving the movable clamp block to slide along the length of the cable groove and clamp the cable. This improves work efficiency and avoids the safety hazards that are prone to occur when working at height.

[0014] 3. This utility model avoids the problem of the clamp body being exposed at high altitudes and easily corroded by long-term exposure to wind and sun by encasing an insulating shell on the outside of the clamp body. In addition, the upper insulating shell is equipped with a pull ring for opening and closing the insulating shell. The insulating shell can be opened and closed by the operator on the ground by inserting the pull ring through the lever, avoiding climbing work and improving work efficiency.
