Description

Technical Field

[0001] This utility model belongs to the field of cable construction, and in particular relates to a dual-station cable unwinding machine for building construction. Background Technology

[0002] In the field of building construction, cable laying is a core component, and its construction efficiency and quality directly determine the stability and safety of the entire electrical system. With the acceleration of urbanization and the continuous expansion of building projects, electrical circuits are becoming increasingly complex, placing higher demands on the continuity, adaptability, and safety of cable laying.

[0003] Currently, most cable unwinding equipment widely used in the industry is designed for a single station, meaning that only one cable roll can be installed at a time. Once a roll of cable is unwound, the machine needs to be stopped to replace it with a new roll, resulting in long idle time for the equipment and making it difficult to meet the continuous operation requirements of large-scale photovoltaic power plant construction.

[0004] Meanwhile, the cable reel fixing structure of existing unwinding machines has limited adaptability. Due to the differences in the diameter and width of cables of different specifications, the support components of traditional equipment often require cumbersome adjustments using multiple bolts. This is not only time-consuming to operate but also lacks stability, easily causing cable reel swaying during unwinding, leading to problems such as cable wear or uneven tension. Utility Model Content

[0005] In view of the above problems, the purpose of this utility model is to provide a dual-station cable unwinding machine for building construction, so as to solve the problems of low efficiency and poor adaptability of existing single-station unwinding machines.

[0006] The present invention adopts the following technical solution:

[0007] The dual-station cable unwinding machine includes a base, a carrier on top of the base, a pair of rotating shafts rotatably mounted on the carrier, the two shafts being arranged in opposite directions and adjacent to each other, a disc on each shaft, a slide rail on the disc facing outwards, a threaded section formed on the outer side of the disc on the shaft, a pair of threaded sleeves slidably mounted on the slide rail, the threaded sleeves being located on the shaft, an adjusting rod inside the shaft, the adjusting rod extending out of the end face of the slide rail, the adjusting rod being rotatable, a connecting plate rotatably mounted around each of the threaded sleeves, an arc-shaped support plate rotatably mounted above each pair of connecting plates, and a detachable baffle mounted on the two opposing support plates.

[0008] Furthermore, the adjusting rod extends out of the end face of the slide and forms a square column.

[0009] Furthermore, the bottom of the baffle has a slot that matches the support plate, and a threaded hole is opened in the baffle directly opposite the slot. An abutment screw is screwed into the threaded hole, and the bottom of the abutment screw resists the support plate.

[0010] Furthermore, each support plate on the disc has a limiting opening, and a pair of limiting wheels are rotatably provided at the tail of the support plate, the limiting wheels passing through and being limited in the limiting opening.

[0011] Furthermore, the inner side of the disk is provided with several reinforcing strips.

[0012] The beneficial effects of this utility model are:

[0013] 1. This device adopts a dual-station design, with two rotating shafts arranged in opposite directions and adjacent to each other. This allows the other station to prepare for roll changing while one station is unwinding, without stopping the machine, which greatly improves work efficiency.

[0014] 2. By rotating the adjusting rod, the threaded sleeve can be moved on the threaded section of the rotating shaft, which in turn drives the support plate to move through the connecting plate, thus achieving the adaptation of cable rolls of different diameters. The adjustment is convenient and does not require cumbersome bolt operations.

[0015] 3. The baffle and the support plate are connected by slots and abutting screws. Combined with the limiting wheel at the tail of the support plate in the limiting port of the disc, the cable roll is fixed more stably, reducing shaking during the unwinding process and reducing the risk of cable wear and uneven tension.

[0020] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0021] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0022] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0023] Combination Figure 1-4 As shown, the dual-station cable unwinding machine includes a base 1, a carrier 2 on top of the base 1, a pair of rotating shafts 3 rotatably mounted on the carrier 2, the two rotating shafts 3 being arranged in opposite directions and adjacent to each other, a disc 4 on the rotating shaft 3, a slide 5 facing outwards on the disc 4, a threaded section formed on the rotating shaft 3 outside the disc 4, a pair of threaded sleeves 6 slidably mounted on the slide 5, and the threaded sleeves 6 being located on the rotating shaft 3, an adjusting rod 7 inside the rotating shaft, the adjusting rod 7 passing through the end face of the slide, the adjusting rod 7 being rotatable, a connecting plate 8 rotatably mounted around the pair of threaded sleeves 6, an arc-shaped support plate 9 rotatably mounted above the pair of connecting plates 8, and a detachable baffle 10 mounted on the two opposing support plates 9.

[0024] This dual-station cable unwinding machine includes a base, on which a carrier provides a stable support foundation for the entire device. A pair of rotating shafts are mounted on the carrier, arranged in opposite directions and adjacent to each other, forming a dual-station structure. This allows for the simultaneous placement of two cable rolls of different specifications or lengths, enabling unwinding at one station while the other station prepares for cable changing, eliminating the need to stop the machine and significantly improving operational efficiency. The inner side of the disc 4 is equipped with several reinforcing strips 16, which enhance the structural strength of the disc and improve the overall stability of the equipment.

[0025] like Figure 3 The adjusting rod 7 extends through the end face of the slide to form a square post 11. In actual use, a square socket wrench can be used to rotate the square post, causing the adjusting rod to rotate as well. This causes the threaded sleeve to move on the threaded section of the rotating shaft. The threaded sleeve, through the connecting plate, moves the support plates, causing the four support plates to retract inward to accommodate the inner diameter of the cable roll. The cable roll is then placed on the mounting frame, and the adjusting rod is rotated in the opposite direction, causing the four support plates to rotate outward a short distance. This tightens the cable roll, making it more securely installed. Finally, two baffles are installed on the corresponding support plates to further secure the cable roll and prevent it from shifting during unwinding.

[0026] In this device, the bottom of the baffle 10 has a slot 12 that matches the support plate, and the baffle has a threaded hole 13 facing the slot. An abutment screw is screwed in through the threaded hole 13, and the bottom of the abutment screw resists the support plate.

[0027] In general, the two baffles are installed symmetrically. When installing the baffles onto the support plate, first align the slots at the bottom of the baffles with the support plate to initially mount the baffles onto the support plate. Then, screw the engagement screws into the threaded holes so that the bottoms of the engagement screws resist the support plate, thus fixing the baffles onto the support plate. As can be seen, the entire installation process of the baffles is relatively simple, saving time and effort.

[0028] As a preferred structure, combined with Figure 4Each support plate on the disc 4 has a limiting opening 14, and a pair of limiting wheels 15 are rotatably provided at the tail of the support plate. The limiting wheels 15 pass through and are limited in the limiting opening 14.

[0029] When the position of the cable sleeve is adjusted by the adjusting rod, thereby moving the support plate to accommodate cable reels of different diameters, the limiting wheels ensure that the support plate can only move along the extension direction of the limiting opening, making the support plate more stable throughout the movement. This also ensures that the two opposing support plates remain symmetrical, guaranteeing that the center of the cable reel is aligned with the center of the rotating shaft, laying the foundation for stable unwinding.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
