Description

Technical Field

[0001] This utility model relates to the field of cable laying technology in communication engineering, specifically to a cable laying device for communication engineering. Background Technology

[0002] Communication cables are key components in communication systems used for signal transmission, widely used in wired, wireless, and network communications. When laying cables, appropriate installation methods must be selected based on the environment. For example, inside buildings, twisted-pair cables can be concealed (by embedding conduits in walls or floors) or exposed (by laying cable trays along walls or ceilings). For optical fibers, excessive bending should be avoided during installation, as a small bending radius can increase signal loss. Generally, the minimum bending radius of optical fibers should be no less than 10-20 times the outer diameter of the fiber. When laying cables outdoors, factors such as moisture and rodent damage must be considered. For example, armored cables (with an added metal armor layer on the outer layer of the cable) can be used to improve the cable's resistance to mechanical damage.

[0003] Currently, when laying communication cables in scenarios such as long-distance ducts, narrow cable trays, or through walls and holes, it usually requires two people to work together. One person pushes the cable at the entrance, and the other person pulls the cable at the exit. The person pushing at the entrance often finds it difficult, especially when the cable is long, has many bends, or has high frictional resistance. The cable is prone to bending, knotting, or getting stuck at the duct entrance, bends, or under its own weight, making it difficult to push and requiring repeated pulling and adjustment, which is inefficient.

[0004] Therefore, a cable laying device for communication engineering is proposed to solve the above problems. Utility Model Content

[0005] 1. Technical problem to be solved by the utility model

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a cable laying device for communication engineering. This device aims to solve the problem that, under current technology, laying communication engineering cables in scenarios such as long-distance ducts, narrow cable trays, or through walls and holes typically requires two people: one to push the cable at the entrance and the other to pull it at the exit. The person pushing the cable at the entrance often finds this strenuous, especially when the cable is long, has many bends, or experiences significant frictional resistance. The cable is prone to bending, knotting, or getting stuck at duct entrances, bends, or under its own weight, leading to difficulties in pushing the cable and requiring repeated pulling and adjustment, resulting in low efficiency.

[0007] 2. Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A cable laying device for communication engineering includes a base, a support frame mounted on the top of the base, the support frame being rotatable on the top of the base, a conveyor roller capable of automatically feeding cables and a cable reel capable of automatically winding cables, the cable reel being capable of uniformly winding cables.

[0010] As a preferred embodiment of this utility model, pulleys are installed at the four corners of the bottom of the base, and positioning plates are symmetrically installed on the bottom edges of the two sides of the base. The top two ends of the positioning plates are symmetrically provided with through holes through which screws can pass.

[0011] As a preferred embodiment of this utility model, a motor is installed inside the base, and a motor shaft driven by the motor is installed on the top of the base. A push rod capable of moving the base is installed at one end of the base, and a controller capable of controlling the start and rotation direction of the motor is installed on the push rod. The bottom center of the support frame is connected to the top of the motor shaft.

[0012] As a preferred embodiment of this utility model, a motor is installed on the outer surface of the lower end of the support frame, and a conveying roller is installed on the inner side of the lower end of the support frame. The motor drives the conveying roller to rotate, and the direction of rotation of the motor is counterclockwise.

[0013] As a preferred embodiment of this utility model, a second motor is installed on the outer surface of the higher end of the support frame, and two conveying rollers are installed vertically on the inner side of the higher end of the support frame. One of the conveying rollers is driven by the second motor, the gap between the two conveying rollers is smaller than the width of the cable, and the second motor rotates clockwise.

[0014] As a preferred embodiment of this utility model, a limiting rotating rod is installed on the inner side of the support frame, and a reciprocating screw is installed on the inner side of the support frame below the bottom of the limiting rotating rod. A guide wheel is sleeved on the reciprocating screw and threadedly connected to it. One end of the cable on the reel passes through the inner side of the guide wheel and then through the gap between the two conveying rollers. The thread size on the reciprocating screw matches the size of the cable.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention uses a motor shaft to drive the base to rotate, which can adjust the direction of cable feeding and winding. The cable on the reel passes sequentially through the inner sides of the limiting rotating rod, the reciprocating screw, and the two conveying rollers. During feeding, the second motor drives the conveying rollers to rotate, using the friction of the conveying rollers to feed the cable. During winding, the first motor drives the reel to rotate, winding the cable onto the reel. No manual feeding or winding is required, saving time and effort, and the operation is simple. At the same time, during the cable feeding and winding process, the reciprocating screw can evenly feed and wind the cable on the reel, thereby effectively improving construction efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figure 1-3 This embodiment provides a cable laying device for communication engineering, including a base 1, a support frame 2 installed on the top of the base 1, the support frame 2 being rotatable on the top of the base 1, a conveyor roller 24 for automatically feeding cables and a cable reel 23 for automatically winding cables on the support frame 2, the cable reel 23 being able to evenly wind the cable, the direction of feeding and winding is adjusted by the rotation of the support frame 2 on the base 1 according to the direction of feeding and winding, the feeding is carried out by the conveyor roller 24 and the winding is carried out by the cable reel 23, saving time and effort, eliminating the need for manual feeding and winding, and the cable is evenly wound on the cable reel 23, improving construction efficiency.

[0025] In this embodiment, as Figure 1 and Figure 2 As shown, pulleys 11 are installed at the four corners of the bottom of the base 1. Positioning plates 12 are symmetrically installed on the bottom edges of both sides of the base 1. The top two ends of the positioning plates 12 are symmetrically provided with through holes through which screws can pass. When the base 1 is pushed to the construction site, in order to ensure that the base 1 will not be pulled when the cable is pushed during the cable winding and unwinding process, expansion bolts can be installed on the ground and installed with the through holes on the positioning plates 12 to fix the position of the base 1.

[0026] In this embodiment, as Figure 1 and Figure 2 As shown, a motor is installed inside the base 1, and a motor shaft 13 driven by the motor is installed on the top of the base 1. A push rod 14 that can push the base 1 to move is installed at one end of the base 1. A controller that can control the start and rotation direction of the motor is installed on the push rod 14. The bottom center of the support frame 2 is connected to the top of the motor shaft 13. When the position of the base 1 is fixed, the support frame 2 is rotated by the motor shaft 13 to adjust the appropriate winding and unwinding direction according to the winding and unwinding direction, so that the winding and unwinding is smoother.

[0027] In this embodiment, as Figure 2 and Figure 3 As shown, a motor 21 is installed on the outer surface of the lower end of the support frame 2, and a conveyor roller 24 is installed on the inner side of the lower end of the support frame 2. The motor 21 drives the conveyor roller 24 to rotate in a counterclockwise direction. When the motor 21 starts, it can retract the cable and wind it onto the reel 23. A motor 22 is installed on the outer surface of the higher end of the support frame 2, and two conveyor rollers 24 are installed vertically on the inner side of the higher end of the support frame 2. One of the conveyor rollers 24 is driven by the motor 22. The gap between the two conveyor rollers 24 is smaller than the width of the cable. The motor 22 rotates clockwise. When the motor 21 is off and the motor 22 is on, it can unload the cable from the reel 23 through the conveyor roller 24.

[0028] In this embodiment, as Figure 3As shown, a limiting rotating rod 25 is installed on the inner side of the support frame 2. A reciprocating screw 26 is installed on the inner side of the support frame 2 below the bottom of the limiting rotating rod 25. A guide wheel is sleeved on the reciprocating screw 26 and threadedly connected to it. One end of the cable on the reel 23 passes through the inner side of the guide wheel and then through the gap between the two conveying rollers 24. The thread size on the reciprocating screw 26 matches the size of the cable. During the cable winding and unwinding process, the cable will drive the guide wheel to rotate on the reciprocating screw 26. Because the guide wheel reciprocates on the reciprocating screw 26, the cable can be evenly wound on the reel 23 or evenly unwinded, avoiding the problem of messy cable caused by manual winding and unwinding.

[0029] Working Principle: When using this cable laying device for communication engineering, the base 1 is first pushed to the construction site. To ensure that the base 1 does not move when the cable is pushed during the cable winding and unwinding process, expansion bolts are installed on the ground and connected to the through holes on the positioning plate 12 to fix the position of the base 1. After the position of the base 1 is fixed, the support frame 2 is rotated by the motor shaft 13 to adjust the appropriate winding and unwinding direction according to the direction of the cable winding and unwinding, making the winding and unwinding smoother. When the motor 21 starts, it can move the cable towards... The cable is collected and wound onto the reel 23. When motor 1 21 is turned off and motor 22 is started, the cable on the reel 23 can be unloaded through the conveyor roller 24. No manual winding or unwinding is required, saving time and effort. The operation is simple. During the winding and unwinding process, the cable drives the guide wheel to rotate on the reciprocating screw 26. Because the guide wheel moves back and forth on the reciprocating screw 26, the cable can be evenly wound onto the reel 23 or evenly unwound, avoiding the problem of messy cable caused by manual winding and unwinding, thus effectively improving construction efficiency.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
