Description

Technical Field

[0001] This utility model relates to the field of cable protection technology, specifically a protective device for construction power cables to prevent dragging damage. Background Technology

[0002] Power cable drag damage protection refers to the protection methods that use technical measures, structural design, or protective devices to prevent mechanical damage to cables caused by dragging behavior such as pulling, friction, squeezing, and torsion during laying, operation and maintenance, and external forces, and to ensure the integrity of the core structure of the cable, such as the insulation layer, shielding layer, and conductor.

[0003] Currently, during construction, cables are usually laid directly on the ground. Due to the complex ground conditions and frequent dragging, the protective layer on the cable surface may crack, exposing the internal metal wires and posing a safety risk. To address this, we propose a protective device for construction power cables to prevent dragging damage. Summary of the Invention

[0004] The purpose of this utility model is to provide a protective device for construction power cables to prevent dragging damage, so as to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions: A protective device for construction power cables to prevent dragging damage includes a storage box. The inner cavity of the storage box is provided with three support mechanisms. Two of the support mechanisms have connecting components on their surfaces and are movably placed inside the storage box. The third support mechanism is fixedly connected inside the storage box.

[0006] The three support mechanisms are used in conjunction to change the support path of the cable.

[0007] The support mechanism includes a fixed frame located on the bottom surface of the inner cavity of the storage box, an adjustable support frame above the fixed frame, a first rotating roller rotatably connected to both sides of the top surface inside the support frame, and a second rotating roller rotatably connected to the bottom of the two side walls of the support frame that are far apart from each other.

[0008] Preferably, the support mechanism further includes a threaded rod rotatably connected to the top plate of the fixed frame, and a limit rod slidably connected to the top plate of the fixed frame. The top end of the threaded rod is rotatably connected to the bottom surface of the support frame, and the top end of the limit rod is fixedly connected to the bottom surface of the support frame.

[0009] Preferably, a placement groove is provided on the bottom plate of the fixed frame, and a counterweight is movably placed in the placement groove.

[0010] Preferably, the top of each of the two side walls of the storage box that are far apart from each other are fixedly connected with an extension rod, and the surface of each of the two extension rods is provided with a hexagonal insertion hole.

[0011] Preferably, the connecting assembly includes a connector fixedly connected to the top of the fixed frame, a rotating rod rotatably connected to the surface of the connector, and a hexagonal plug fixedly connected to the end of the rotating rod away from the connector, the hexagonal plug being movably inserted into a hexagonal plug hole.

[0012] Preferably, a reinforcing plate is fixedly connected to each of the four corners of the bottom surface of the storage box, and a reinforcing hole is opened through the surface of each of the four reinforcing plates, and a reinforcing rivet is movably inserted into each of the four reinforcing holes.

[0013] Preferably, the fixing frame of the support mechanism, which is fixedly connected inside the storage box, is fixedly connected to the storage box.

[0014] The beneficial effects of this utility model are: This invention utilizes rotating rollers, hexagonal inserts, and hexagonal insertion holes. By removing two movable fixing frames from the storage box and inserting the hexagonal inserts on the two movable fixing frames into the hexagonal insertion holes on both sides of the storage box, and by placing the cable on three second rotating rollers for pulling, it prevents the cable from dragging on the ground and causing damage. The rotation of the second rotating rollers further reduces friction between the cable and the frame. Changing the insertion direction of the hexagonal inserts alters the angle of the fixing frames, thus changing the cable's transport direction. The contact between the first rotating rollers on both sides of the support frame and the cable reduces lateral friction, protecting the cable and preventing damage to the cable's protective layer caused by frequent dragging, thereby enhancing cable safety.

The third support mechanism 6 is fixedly connected inside the storage box 1. The three support mechanisms 6 work together to change the cable support path. Each support mechanism 6 includes a fixed frame 61 located on the bottom surface of the storage box 1's cavity. An adjustable support frame 65 is located above the fixed frame 61. First rotating rollers 66 are rotatably connected to both sides of the top surface inside the support frame 65. Second rotating rollers are rotatably connected to the bottom of the two mutually distant side walls of the support frame 65. 67. Extension rods 2 are fixedly connected to the top of the two side walls of the storage box 1 that are far apart from each other. Hexagonal insertion holes 3 are opened through the surface of the two extension rods 2. The connecting component 7 includes a connector 71 fixedly connected to the top of the fixed frame 61. A rotating rod 72 is rotatably connected to the surface of the connector 71. A hexagonal insertion rod 73 is fixedly connected to the end of the rotating rod 72 that is away from the connector 71. The hexagonal insertion rod 73 is movably inserted into the hexagonal insertion hole 3. Reinforcing plates 4 are fixedly connected to the four corners of the bottom surface of the storage box 1. Reinforcing holes 5 are opened through the surface of the four reinforcing plates 4. Reinforcing rivets are movably inserted into the four reinforcing holes 5. The fixed frame 61 of the support mechanism 6 fixedly connected inside the storage box 1 is fixedly connected to the storage box 1.

[0019] In practice, by removing the two movable fixed frames 61, inserting the hexagonal rods 73 on the two fixed frames 61 into the hexagonal insertion holes 3 on both sides of the storage box 1, and pulling the cable on the three second rotating rollers 67, damage caused by the cable dragging on the ground can be prevented. The rotation of the second rotating rollers 67 can further reduce the friction between the cable and the fixed frame 61. By changing the insertion direction of the hexagonal rods 73, the angle of the fixed frame 61 can be changed, thereby changing the cable conveying direction. By using the first rotating rollers 66 on both sides of the support frame 65 to contact the cable, the lateral friction of the cable can be reduced, thereby protecting the cable.

A placement groove is provided on the bottom plate of the fixed frame 61, and a counterweight 62 is movably placed in the placement groove.

[0022] In practice, by rotating the threaded rod 63 to drive the support frame 65 to rise, the support height of the cable can be adjusted to the specified height for use, thus enhancing the practicality of the device. By placing the counterweight 62 in the placement slot, the stability of the fixed frame 61 during use can be enhanced.

[0023] In use, the two movable fixing frames 61 are removed, and the hexagonal rods 73 on the two fixing frames 61 are respectively inserted into the hexagonal insertion holes 3 on both sides of the storage box 1.
