Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and in particular to a cable laying device for laying electrical cables in buildings. Background Technology

[0002] Wires and cables are wire products used to transmit electrical energy, electrical signals, and realize electromagnetic energy conversion. Cables are usually composed of a core that transmits power or electrical signals and an outer shell that provides protection and insulation. Cables containing only one core and with a relatively small diameter are usually called wires. Some wires do not have an insulating sheath and are called bare wires. The core of a cable is made of a metal material with good conductivity.

[0003] Publication number CN219730183U discloses a cable laying device for building electrical cables, including a carrying mechanism and a cable laying mechanism. The cable laying mechanism is rotatably connected to the top of the carrying mechanism and includes a winding unit and a guiding unit. The winding unit is rotatably connected to the top of the carrying mechanism, and the guiding unit is fixedly connected to the top of the carrying mechanism. The carrying mechanism consists of a base plate, a first support leg, a slider, and a second support leg. This cable laying device for building electrical cables uses a drive component to drive the second guide wheel to rotate, which, in conjunction with the first guide wheel, adjusts the spacing, facilitating the transmission of cables of different thicknesses. It eliminates the need for manual rotation and allows for rapid cable laying. The drive component drives a transmission component, which in turn drives a rotating rod and a winding roller to rotate, enabling rapid loading of cables and winding of excess cable, thus improving the practicality of the device.

[0004] While the above solutions can quickly load cables and reel in excess cable, the cable laying operation requires a motor drive, resulting in high operating costs. Furthermore, the cable is rigidly clamped and fixed, leading to mediocre cable laying performance. Therefore, we propose a cable laying device for laying electrical cables in buildings. Utility Model Content

[0005] The main purpose of this utility model is to provide a cable laying device for building electrical cables. By setting an adjustment drive unit and a guide unit, it solves the problems of high operating costs due to the need for motor drive in cable laying operations and the poor cable laying effect when the cable is rigidly clamped and fixed.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a cable laying device for laying electrical cables in buildings, including a carrier plate and a winding drum, and further including: an adjustment drive unit disposed between the carrier plate and the winding drum and a guide unit disposed on the carrier plate;

[0007] The adjustment drive unit includes a slide rod, a support frame, a rotating shaft, a drive motor, and a push-pull screw. A strip-shaped groove is formed on the top surface of one side of the carrier plate. The slide rod is fixedly mounted on the strip-shaped groove. The support frame is U-shaped and movably sleeved on the slide rod. The rotating shaft is movably mounted on the support frame. The winding spool is fixedly sleeved on the outer circumference of the middle end of the rotating shaft. The drive motor is fixedly mounted on the top surface of the carrier plate, and a rectangular insertion block is fixedly mounted on its output end. A rectangular insertion slot is formed on the end face of the rotating shaft. The rectangular insertion block movably extends into the rectangular insertion slot. The push-pull screw is threaded to one side surface of the carrier plate, and one end of the push-pull screw extending into the strip-shaped groove is connected to the side of the support frame through a bearing.

[0008] The guiding unit includes a fixed frame, a lower roller, a support spring, an adjusting frame, an upper roller, and a lifting rod. The fixed frame is in the shape of an inverted "U" and is fixedly installed on the top surface of the other side of the carrier plate. The lower roller is installed on the inner wall of the bottom end of the fixed frame through a first support rod. A strip-shaped through groove is opened on each of the opposite sides of the fixed frame. The support spring is fixedly installed on the top wall of the strip-shaped through groove. The adjusting frame is in the shape of an inverted "U" and is fixedly installed at the bottom end of the support spring. The upper roller is installed on the inner wall of the adjusting frame through a second support rod and is located directly above the lower roller. The lifting rod is fixedly installed at the center of the top surface of the adjusting frame and moves through the top surface of the fixed frame.

[0009] Preferably, the push-pull screw and the slide rod are arranged parallel to each other.

[0010] Preferably, a turntable is fixedly installed at one end of the push-pull screw located on the outer side of the carrier plate.

[0011] Preferably, there are two support springs, which are symmetrically arranged on the top surface of the adjustment frame.

[0012] Preferably, the lifting rod and the upper roller are arranged perpendicular to each other.

[0013] Preferably, casters are fixedly installed at the corners of the bottom surface of the carrier plate.

[0014] Compared with the prior art, the cable laying device for building electrical cables of this utility model has the following advantages:

[0015] 1. In this utility model, by setting an adjustment drive unit, when performing winding or unwinding operations, the push-pull screw connected to one side surface of the carrier plate is held and rotated. The push-pull screw connected to the side of the support frame via the bearing can push or pull the support frame. The U-shaped support frame can slide and move on the slide rod in the strip groove. The rotating shaft movably set on the support frame can adjust the distance between itself and the rectangular plug block on the output end of the drive motor. After the rectangular plug slot on the rotating shaft is connected to the rectangular plug block, the drive motor can drive the rotating shaft to rotate to assist the winding drum in the winding operation. After the rotating shaft is disengaged from the rectangular plug block, the rotating shaft can rotate freely with the winding drum to complete the unwinding operation. The unwinding operation of the equipment does not require motor drive, resulting in low operating costs.

[0016] 2. In this utility model, the cable being released can pass between the upper roller and the lower roller. The support spring, which is fixedly installed on the top wall of the strip groove, helps the upper roller to flexibly clamp the cable downwards. When the cable is pulled out, the support spring can deform and extend to change within a certain range in coordination with the distance between the upper roller and the lower roller to ensure a smooth cable release process. By holding and lifting the lifting rod, the adjusting frame drives the upper roller to move upwards, and the support spring is compressed accordingly. After the cable passes between the upper roller and the lower roller, the lifting rod is released, and the deformation of the support spring returns to normal, which can drive the upper roller to move downwards and reset to maintain the flexible clamping effect. The equipment has a flexible clamping and fixing effect on the cable, and its cable release effect is stable. Attached Figure Description

After the rectangular plug-in slot on the rotating shaft 203 is connected to the rectangular plug-in block, the drive motor 204 drives the rotating shaft 203 to rotate to assist the winding drum 3 in the winding operation. After the rotating shaft 203 disengages from the rectangular plug-in block, the rotating shaft 203 cooperates with the winding drum 3. The cable release operation is completed by free rotation. The support spring 403, which is fixed on the top wall of the slot, helps the upper roller 405 to flexibly clamp the cable downward. When the cable is pulled out, the support spring 403 deforms and expands in coordination with the distance between the upper roller 405 and the lower roller 402 to ensure a smooth cable release process. By holding and moving the lifting rod 406 upward, the adjusting frame 404 drives the upper roller 405 to move upward, and the support spring 403 is compressed accordingly. After the cable passes between the upper roller 405 and the lower roller 402, the lifting rod 406 is released, and the support spring 403 deforms and returns to its original position, causing the upper roller 405 to move downward and reset to maintain the flexible clamping effect.
