Description

A wire protection rope cross-arm connection device

technical field

The utility model relates to a wire protection rope cross-arm connecting device.

Background technique

When daily power outages or live inspections need to move wires, increase wire clamps, or replace insulator strings, etc., if a single suspension wire device is used, a back protection rope must be used to prevent wires from falling off according to safety regulations, but the existing protection rope hangs The device is a hook that loops through the main material of the tower and buckles to the protection rope. It is obvious that the protection rope will be damaged due to friction with the pole tower and the hook after being used many times like this, so that its service life is greatly shortened. Moreover, the friction between the insulation protection rope and the hook or the angle iron of the main material will also make it stained with metal powder, which will reduce its insulation performance and endanger the safety of live work. The drooping metal hook will also short the effective insulation distance. Nowadays, live work generally adds a protective cover to the insulating rope where the hook is fixed, but the protective cover is not made of insulating material, and it is easy to short the effective insulation length.

Utility model content

The purpose of this utility model is to overcome the shortcomings of the above-mentioned prior art, and provide a wire protection rope cross-arm connection device, which can quickly and firmly fix the wire protection rope to the main material of the cross-arm, and lock the device reliably. The hook is directly hung on the main material, and the insulating rope does not need to be looped through the main material, which avoids the friction between the insulating rope, the main material and the hook, improves the service life of the protection rope, and avoids the situation that the hook and the protection rope cover short the effective insulation distance .

In order to achieve the above object, the utility model adopts the following technical solutions:

A wire protection rope cross-arm connection device, including a hook, the hook is an inverted U-shaped structure, the hook is hung on the angle iron of the main material of the pole tower, and one end of the inverted U-shaped opening of the hook extends out and is connected with an inverted L Type baffle, the hook and the baffle are integrally formed, and the lower side of the inverted U-shaped opening on the hook is connected with a locking device to prevent the hook from detaching from the angle iron of the main material of the pole tower. The extension part of the baffle and the hook An inverted U shape is formed, and the space formed by the baffle plate and the extension part of the hook is connected with a wire protection rope.

The width of the inverted U-shaped opening of the hook is greater than the thickness of the angle iron of the main material of the pole tower, which can meet the thickness of the angle iron of the main material of various tower types.

The locking device is a bolt, which passes through the iron plate of the hook, and the head of the bolt can be rotated to adjust its penetration depth. Before hanging, the bolt should be unscrewed (the screw should not expose the plane on the right side of the hook), so that the hook can be hung on the hook smoothly. The main material of the tower is on the angle iron. After hanging, turn the bolt, and the protruding screw rod at this time can be used as a locking device to prevent the hook from coming out of the angle iron.

The wire protection rope is connected with the baffle plate and the extension part of the hook through bolts. The bolt is unscrewed from the threaded hole of the extension part of the hook, passes through the wire protection rope, and plays the role of connecting the wire protection rope.

The utility model has the beneficial effects of being simple and fast, avoiding the friction between the insulating rope, the main material and the hook, improving the service life of the protection rope, and avoiding the situation that the hook and the protection rope cover are short-circuited with the effective insulation distance.

Description of drawings

Fig. 1 is the structural representation of the utility model wire protection rope cross-arm connecting device;

Fig. 2 is a side view of the wire protection rope cross-arm connecting device of the present invention;

Among the figure, 1 is a hook, 2 is the angle iron of the main material of the tower, 3 is a bolt, 4 is a baffle plate, 5 is a wire protection rope, and 6 is a bolt hole.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Figure 1, the wire protection rope crossarm connection device includes a hook 1, which is an inverted U-shaped structure. The hook 1 is hung on the angle iron 2 of the main material of the tower. One end of the inverted U-shaped opening of the hook 1 is extended and connected There is an inverted L-shaped baffle 4, the hook 1 and the baffle 4 are forged from a single steel plate, the hook 1 and the baffle 4 are provided with bolt holes 6, and the bolt holes 6 are pierced with bolts 3, and one of the bolts 3 is on the hook 1. Upside down the lower side of the U-shaped opening and pass through the iron plate of the hook. The head of the bolt 3 can be rotated to adjust its penetration depth. Before hanging, the bolt 3 should be unscrewed out (screw 3 should not be exposed to the plane on the right side of the hook). In order to successfully hang the hook 1 on the main material angle iron 2 of the tower. After hanging, the bolt 3 is rotated, and the screw rod stretched out at this time can be used as a locking device to prevent the hook 1 from coming out of the main material angle iron 2 of the pole tower. The baffle 4 and the extension of the hook 1 form an inverted U shape, and the space formed by the baffle 4 and the extension of the hook 1 is connected with a wire protection rope 5 through a bolt 3 . The bolt is unscrewed from the threaded hole of the extension part of the hook, passes through the wire protection rope, and plays the role of connecting the wire protection rope. The width of the inverted U-shaped opening of the hook 1 is greater than the thickness of the angle iron of the main material of the pole tower, which can meet the thickness of the angle iron of the main material of various tower types.

As shown in Figure 2, the wire protection rope cross-arm connection device, the width of the hook 1 and the baffle 4 is 40mm, the length of the whole device is 330mm, the bolt holes on the hook 1 and the baffle 4 can be determined according to the actual size of the bolts , but the strength of the steel plate after punching should meet the load requirements and have a certain safety margin.

The utility model is suitable for live or power failure maintenance operations. When a single suspension wire device is used for operations such as moving wires, increasing wire clamps, and replacing insulator strings, a backup protection rope for preventing wires from falling off is required. The device is used to hang the protection rope on the cross arm firmly and reliably without damaging the insulation protection rope.

Although the specific implementation of the utility model has been described above in conjunction with the accompanying drawings, it does not limit the protection scope of the utility model. Those skilled in the art should understand that on the basis of the technical solution of the utility model, those skilled in the art do not need to Various modifications or deformations that can be made with creative efforts are still within the protection scope of the present utility model.
