Description

Technical Field

[0001] This application relates to the field of building electrical construction technology, specifically to a wiring device for building electrical construction. Background Technology

[0002] Building electrical construction refers to a series of operations in which electrical wiring, electrical equipment installation and commissioning are carried out in a building in accordance with electrical design drawings and relevant specifications. In the process of electrical construction, a cable puller is an important auxiliary tool. Its core function is to help construction workers to smoothly pass wires, cables and other materials through pre-buried pipes or cable trays.

[0003] A wiring harness for building electrical construction, application number CN202420399828.8, includes a wiring harness body and a first bearing symmetrically mounted on the wiring harness body. A rotating shaft is fixedly mounted on the inner ring of the first bearing, and a rotating cylinder is fixedly connected to one end of the rotating shaft. A frame is symmetrically arranged inside the wiring harness body, and a support plate is arranged inside the frame. Three sets of positioning blocks are fixedly connected to the support plate, and a guide component is arranged inside the frame.

[0004] However, when threading wires manually in the traditional way, workers rely more on feel to apply force, making it difficult to maintain even pressure. This can easily lead to sudden over- or under-force application: over-force may cause the wire to suddenly tighten, increasing the risk of wire stretching; under-force may cause the wire to slack in the channel, requiring repeated pulling and adjustment, which reduces the stability of the threading process. The aforementioned wire threader for building electrical construction has certain shortcomings. Its drum rotation speed depends on the worker's pulling force and speed, and it cannot automatically adjust the rotation speed to regulate the pulling force of the cable. This increases the force required for workers when threading wires, which is not conducive to conserving physical strength.

[0005] Therefore, it is necessary to provide a wiring device for building electrical construction to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a wiring device for building electrical construction, which solves the problem that when wiring is done manually, workers rely more on feel to determine the amount of force applied, making it difficult to maintain uniform force and easily resulting in sudden excessive or insufficient force.

[0008] The technical solution adopted by this application to solve its technical problem is: a wiring device for building electrical construction, including a mounting frame, on which a transmission component and a wiring component are respectively provided, two support rods are connected to the top of the mounting frame, a drive source is connected to the top of the two support rods, and a reinforcing plate is connected to the surface of the mounting frame; The surface of the transmission component is connected to the power output end of the drive source to drive the transmission component to perform variable speed transmission rotation. The surface of the threading assembly is poweredly connected to the power output end of the transmission assembly for threading.

[0009] Furthermore, the transmission assembly includes a worm gear and a transmission rod. The worm gear is disposed on the power output end of the drive source. The surface of the transmission rod is rotatably connected to the inner side of the reinforcing plate through a bearing. A worm wheel is connected to the surface of the transmission rod, and a connecting rod is connected to one side of the worm wheel.

[0010] Furthermore, the surface of the worm is rotatably connected to the inner top of the mounting bracket via a bearing, and the bottom end of the worm is rotatably connected to the inner bottom end of the mounting bracket via a bearing.

[0011] Furthermore, the surface of the transmission rod is rotatably connected to the interior of one side of the mounting bracket via a bearing.

[0012] Furthermore, the worm gear is engaged with the worm.

[0013] Furthermore, the threading assembly includes two limiting discs and two threading wheels. One of the limiting discs is located at one end of the connecting rod, and a winding roller is connected between the two limiting discs. Two threading wheels are rotatably connected to the inner side of the other limiting disc, and the surface of the winding roller is provided with the cable body.

[0014] Furthermore, the surface of the cable body is in contact with the surfaces of the two threading wheels.

[0015] The beneficial effects of this application are as follows: The wire puller for building electrical construction provided by this application drives the worm gear to rotate via a drive source, which facilitates the worm wheel to rotate at varying speeds according to the required pulling speed for wire pulling. This allows the rotation speed of the winding roller to be flexibly adjusted according to the actual force and rhythm of the worker pulling the wire, ensuring that the wire pulling speed is always adapted to the worker's operating habits and the internal conditions of the channel. This reduces operational jams or errors caused by speed mismatch. The rotational connection of the wire puller helps to reduce wear between the cable body and the limit plate, thereby protecting the insulation layer on the surface of the cable body. Furthermore, the transmission between the worm gear and the worm wheel itself has the characteristics of smooth transmission and low noise. After the speed is changed with the worm wheel, it helps to buffer the fluctuations in the force when the worker pulls the wire, avoiding sudden stress or loosening of the cable body due to uneven manual force, further improving the stability of the wire pulling process, and helping to conserve the worker's energy.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] like Figure 1-4 As shown, this application provides a wiring harness for building electrical construction, including a mounting frame 1. The mounting frame 1 is respectively provided with a transmission component 2 and a wiring component 3. Two support rods are connected to the top of the mounting frame 1 to provide support for the drive source 4 and avoid swaying. The top of the two support rods is connected to the drive source 4. A reinforcing plate 5 is connected to the surface of the mounting frame 1 to provide stable support. The surface of the transmission component 2 is connected to the power output end of the drive source 4 to drive the transmission component 2 to perform variable speed transmission rotation; The surface of the threading assembly 3 is poweredly connected to the power output end of the transmission assembly 2 for threading.

[0021] The transmission assembly 2 includes a worm gear 21 and a transmission rod 22. The worm gear 21 is located on the power output end of the drive source 4. The surface of the transmission rod 22 is rotatably connected to the inner side of the reinforcing plate 5 through a bearing. The reinforcing plate 5 provides support for the transmission rod 22 and prevents the transmission rod 22 from falling off. A worm wheel 23 is connected to the surface of the transmission rod 22, and a connecting rod 24 is connected to one side of the worm wheel 23.

[0022] The surface of the worm 21 is rotatably connected to the inner top of the mounting bracket 1 via a bearing, and the bottom end of the worm 21 is rotatably connected to the inner bottom of the mounting bracket 1 via a bearing.

[0023] The surface of the transmission rod 22 is internally rotatably connected to one side of the mounting bracket 1 via a bearing, which helps to improve the stability of the rotation of the transmission rod 22 and the worm gear 23.

[0024] The worm gear 23 is meshed with the worm 21. The worm 21 can easily drive the worm gear 23 to rotate at different speeds. The transmission between the worm 21 and the worm gear 23 is characterized by smooth transmission and low noise. After the speed is changed with the worm gear 23, it helps to buffer the force fluctuation when the worker pulls the wire.

[0025] The cable threading assembly 3 includes two limiting discs 31 and two threading wheels 33. One of the limiting discs 31 is located at one end of the connecting rod 24. A winding roller 32 is connected between the two limiting discs 31 to facilitate the winding of the cable body 34. The inner side of the other limiting disc 31 is rotatably connected to two threading wheels 33. The surface of the winding roller 32 is provided with the cable body 34.

[0026] The surface of the cable body 34 is in contact with the surfaces of the two threading wheels 33. By rotating the threading wheels 33, wear between the cable body 34 and the limiting disc 31 can be reduced, thereby protecting the insulation layer on the surface of the cable body 34.

[0027] Working principle: First, the mounting frame 1 is installed at the construction position where the cable needs to be threaded, and the cable body 34 is pre-wound around the surface of the winding roller 32. At this time, the position of the cable body 34 is pre-positioned. Then, the drive source 4 drives the worm gear 21 to rotate at a variable speed according to the required pulling speed for threading, thereby driving the worm wheel 23 meshing with the worm gear 21 to rotate at a variable speed, which in turn drives the winding roller 32 to rotate at a variable speed. This allows the rotation speed of the winding roller 32 to be flexibly adjusted according to the actual force and rhythm of the worker pulling the cable, so that the threading speed is always adapted to the worker's operating habits and the internal conditions of the channel, reducing the impact of speed. To prevent operational delays or errors caused by mismatch in the degree of rotation, a threading wheel 33 is installed on the rotating limit plate 31. The threading wheel 33 is in close contact with the cable body 34, which helps to reduce wear between the cable body 34 and the limit plate 31, thereby protecting the insulation layer on the surface of the cable body 34. Furthermore, the transmission between the worm gear 21 and the worm wheel 23 is characterized by smooth transmission and low noise. After the speed is changed with the worm wheel 23, it helps to buffer the fluctuation of force when the worker pulls the cable, and avoids sudden stress or loosening of the cable body 34 due to uneven manual force. This further improves the stability of the threading process and helps to maintain the worker's physical strength.

[0028] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
