Description

Technical Field

[0001] This utility model relates to the technical field of electrical construction wiring tools, specifically an indoor wiring device for electrical construction. Background Technology

[0002] In electrical construction, indoor wiring laying devices are essential tools, primarily used to ensure accurate cable length, efficient operation, and safe and orderly cable laying. Their functions include helping construction workers control cable length, preventing cables from being too long or too short, thus improving construction quality and work efficiency. Their structure typically consists of a reel or spool, a support, a bearing system, a handle or knob, a guide device, and a storage space. The reel or spool is the core component, used for winding and releasing the cable. The support holds the reel for stability, the bearing system allows for smooth rotation, the handle controls the cable release speed, the guide device ensures the cable is straight and smooth, and the storage space facilitates the storage of spare cables or tools. When using the device, construction workers need to prepare the cable, fix it to the reel, place the laying device securely, and gradually rotate the handle to control the cable release, paying attention to the straightness and tension of the cable to avoid kinking or breakage.

[0003] As disclosed in the power cable installation and wiring device with authorization announcement number CN219351128U, the wiring frame has two sets of sliding grooves spaced apart, and a cable support frame is slidably connected in the two sets of sliding grooves. A screw threadedly connected to the cable support frame is rotatably connected to the wiring frame. The screw is driven by a power device. The cable support frame has a placement groove, and an auxiliary roller is fitted in the placement groove. A coil body is fitted on the auxiliary roller. The auxiliary roller is controlled by a controller to start a motor to drive the screw, which can adjust the height of the cable placement frame. It is suitable for coils of different diameters and achieves convenient adjustment. When it is necessary to stop the coil, the extension rod is activated to make the brake plate engage with the coil to prevent the coil from continuing to rotate due to inertia. The roller in the above technical solution is horizontal, which means that once the cable specifications change, such as from a thinner control wire to a thicker power wire, or from a single-core wire to a multi-core wire, the original cable laying device may not be able to adapt. This is because different cables vary significantly in parameters such as diameter, flexibility, and weight, making it difficult for a single-specification roller to meet diverse needs. Furthermore, due to the horizontal roller design, cables are typically wound along the axial direction, requiring them to be removed from one or more ends or unwound from the roller for loading and unloading. This makes changing cables of different specifications cumbersome and time-consuming, especially in situations with limited space and a wide variety of cables, where frequent cable replacements can severely impact construction efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an indoor wiring device for power construction, wherein multiple support columns perpendicular to the ground are installed on the top of a rotatable tray, and cable reels are fitted onto the support columns. The cable wires on the support columns are led out from the conductor and used for wiring and laying operations, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an indoor wiring device for power construction, comprising a bottom shell, a tray rotatably mounted on the top of the bottom shell, and a plurality of lower expansion sleeves arranged in a ring at equal intervals at the edge of the top of the tray. The top of each lower expansion sleeve is equipped with a support column, and the tops of the plurality of support columns are connected to a tray cover. A wire guide is installed on the outer wall of the tray below the lower expansion sleeves, and the wire guide is used to guide the cable roll on the support column to be pulled out.

[0006] Preferably, a rotary drive unit for driving the tray to rotate is installed inside the bottom shell, and a motor controller electrically connected to the input terminal of the rotary drive unit is installed on one outer wall of the bottom shell.

[0007] Preferably, the rotary drive unit includes an H-shaped base integrally formed on the bottom of the base shell, a geared motor mounted on the bottom end of the H-shaped base, and a main shaft mounted on the top end of the geared motor drive shaft, with the top end of the main shaft fixedly connected to the bottom end of the tray.

[0008] Preferably, an arc-shaped baffle is integrally formed on the upper surface of the tray on one side of the lower expansion sleeve, and the arc-shaped baffle is concentric with the lower expansion sleeve.

[0009] Preferably, the bottom end of the disc cover is bolted with an upper expansion sleeve that is concentric with the lower expansion sleeve.

[0010] Preferably, the conductor includes a support arm fixed to the outer wall of the tray, a rectangular sleeve slidably mounted on one end of the support arm surface, a U-shaped frame welded and fixed to the top of the rectangular sleeve, and a hollow steel sleeve mounted on the top of the U-shaped frame. The end of the support arm away from the tray has an integrally formed vertically upward protrusion.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This indoor wiring device for power construction utilizes a structure consisting of a tray, a lower tension sleeve, support columns, a tray cover, and a conductor guide, all working together. Multiple support columns perpendicular to the ground are mounted on the top of the rotatable tray. Cable reels are mounted on these support columns, and the cables are led out from the conductor guide for wiring and laying operations. By mounting multiple support columns on the top of the tray, each column can specifically store different types and specifications of cables. The cable reels mounted on the support columns prevent cables from getting mixed up during laying, reducing the possibility of tangling and knotting. This not only makes cable management clearer but also facilitates quick location of required cables by construction personnel, saving search and replacement time and improving construction efficiency. Secondly, the rotatable design of the tray allows the position of the support columns to be adjusted according to construction needs, and the cable lead-out direction can be flexibly changed to adapt to different construction scenarios and wiring routes. Finally, the cable reels mounted on the support columns provide good support and protection for the cables during storage and laying, reducing friction and pulling between the cables and the ground or other hard objects, thereby reducing the risk of cable breakage or damage. Meanwhile, the cable is led out from the cable guide and follows a reasonable guide path to avoid kinking or tangling during the cable laying process, ensuring the linearity and integrity of the cable.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the 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 scope of protection of the present utility model.

[0019] Please see Figure 1-5 An embodiment of this utility model provides an indoor wiring device for power construction, comprising a base shell 1, a tray 2 rotatably mounted on the top of the base shell 1, and a plurality of lower expansion sleeves 3 arranged in a ring at equal intervals at the top edge of the tray 2. The top of the lower expansion sleeves 3 is equipped with support columns 4, and the tops of the plurality of support columns 4 are connected to a disc cover 5. A wire guide 9 is installed on the outer wall of the tray 2 below the lower expansion sleeves 3. The wire guide 9 is used to guide the cable roll on the support column 4 to be pulled out.

[0020] The bottom shell 1 is equipped with a rotary drive unit 11 for driving the tray 2 to rotate, and a motor controller 10 that is electrically connected to the input terminal of the rotary drive unit 11 is installed on one outer wall of the bottom shell 1.

[0021] The rotary drive unit 11 includes an H-shaped base 1101 integrally formed on the bottom of the base shell 1, a geared motor 1102 mounted on the bottom of the H-shaped base 1101, and a main shaft 1103 mounted on the top of the drive shaft of the geared motor 1102. The top of the main shaft 1103 is fixedly connected to the bottom of the tray 2. When using the cable roll on the support column 4, the operator starts the geared motor 1102 through the motor controller 10. The motor controller 10 controls the geared motor 1102 to work according to the set direction, speed, angle, and response time. The geared motor 1102 drives the tray 2 to rotate through the main shaft 1103. At this time, the support column 4 revolves around the center of the tray 2 to change the position of the support column 4 and the cable roll, so as to facilitate the selection of the corresponding cable roll.

[0022] An arc-shaped baffle 7 is integrally formed on the upper surface of the tray 2 on one side of the lower tension sleeve 3. The arc-shaped baffle 7 and the lower tension sleeve 3 are concentric. The arc-shaped baffle 7 is used to separate two adjacent support columns 4 so that adjacent cable rolls can be wrapped and knotted.

[0023] The bottom end of the cover 5 is bolted with an upper expansion sleeve 6 that is concentric with the lower expansion sleeve 3. The bottom end of the support column 4 is connected to the tray 2 through the lower expansion sleeve 3, and the top end of the support column 4 is connected to the bottom end of the cover 5 through the upper expansion sleeve 6, so as to achieve the purpose of quick assembly and disassembly of the support column 4 and the cover 5.

[0024] The cable guide 9 includes a support arm 8 fixed to the outer wall of the tray 2, a rectangular sleeve 901 slidably mounted on one end of the surface of the support arm 8, a U-shaped frame 902 welded and fixed to the top of the rectangular sleeve 901, and a hollow steel sleeve 903 mounted on the top of the U-shaped frame 902. The cable passes through the hollow steel sleeve 903 and is led to the point of use. The end of the support arm 8 away from the tray 2 has an integrally formed vertically upward protrusion 801. The rectangular sleeve 901 is manually slidable so that it slides in the extension direction of the support arm 8. The protrusion 801 is used to prevent the rectangular sleeve 901 from being drawn off the support arm 8, thereby adjusting the distance between the hollow steel sleeve 903 and the support column 4.

[0025] In this embodiment, the following steps are taken: First, prepare the required cable reels according to construction needs, confirm that the cable specifications, length, and quantity meet the design requirements, and organize the cables to avoid knots and tangles. Securely install the bottom of the support column 4 onto the top of the tray 2 using the lower tension sleeve 3, and then place the cable reel onto the support column 4. Subsequently, install the reel cover 5 on the top of multiple support columns 4. The reel cover 5 protects the cables and prevents them from slipping off the support columns 4 during the cable laying process. Lead the cables out from the cable guide 9 and gradually release them along the predetermined path. Workers should hold the cables gently to avoid excessive pulling. During the cable laying process, workers should observe the condition of the cables and adjust the tightness of the cables in a timely manner to prevent tangling or knots. After the cable laying is completed, tighten any excess cable on the support column 4 to prevent the cables from scattering on the ground and causing safety hazards.
