Description

Technical Field

[0001] The utility model relates to the field of cable laying, in particular to a long-distance high-voltage cable laying protection frame. Background Art

[0002] Cable laying refers to the way the cable is laid from the distribution box to the electrical equipment or another distribution box. For example, it can be laid concealed or openly along the ground, wall, or ceiling. Cable laying in bridges, cable trenches, and cable troughs are all commonly used cable laying methods. The appropriate cable laying method should be selected according to different environments, conditions, and properties. When the horizontal channel contains high-voltage cables above 35kV, or to meet the requirements of the allowable bending radius for the cables introduced into the cabinet, they should be arranged in a "bottom-to-top" order.

[0003] However, when laying high-voltage cables above 35kV, due to the weight and large diameter of the cables, the cables in the upper position are easily squeezed and fall into the cables in the lower position when they are laid directly. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a long-distance high-voltage cable laying protection frame, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: a long-distance high-voltage cable laying protection frame, comprising a mounting frame and a support frame, the upper surface array of the support frame is provided with a cable clamp, the cable clamp comprises: a first arc plate, a second arc plate, a connecting arc plate is provided on the outer side of one end of the first arc plate and the second arc plate, a bolt plug plate is provided on the end of the first arc plate away from the connecting arc plate, a movable groove is provided on the end of the second arc plate away from the connecting arc plate, a fastening screw is installed inside the bolt plug plate, and a fastening nut is provided on the outer side of the fastening screw.

[0006] As a further solution of the utility model: a rotating ear plate is installed on the lower surface of the support frame, an inclined support frame is arranged inside the rotating ear plate, and positioning holes are provided at the lower end of the inclined support frame and the side surface of the mounting frame.

[0007] As a further solution of the utility model: a mounting bolt is installed inside the positioning socket, and a mounting ear plate is installed on the outer side wall of the mounting frame.

[0008] As a further solution of the utility model: a movable pin is connected between the first arc plate, the second arc plate and the connecting arc plate.

[0009] As a further solution of the utility model: the first arc plate is fixedly connected to the support frame through the bolt insert plate.

[0010] As a further solution of the present invention: the inclined support frame is rotatably connected to the rotating ear plate.

[0011] As a further solution of the utility model: a rotating shaft is installed between the support frame and the mounting frame.

[0012] As a further solution of the present invention: the mounting ear plate is fixedly connected to the mounting frame.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] Open the first arc plate and the second arc plate, and then rotate the support frame as a whole to be parallel to the ground. Then, the cables can be conveniently lifted to a lower height inside the multiple first arc plates and placed on the first arc plates for support. After the support frame is rotated upward as a whole, the inclined support frame can be used to support the cables.

[0015] The cable clamps arranged in an array on the upper surface of the support frame can be used to install cables. After the lower-level cable limiters are installed, the gap between two adjacent cable clamps is used to limit the position above the stacking, which can ensure that the cables in the upper position will not be squeezed and fall below. The cables in the upper position are then fixed with binding tapes to ensure the laying of the cables. BRIEF DESCRIPTION OF THE DRAWINGS
