Description

Technical Field

[0001] This application relates to the field of cable winding and unwinding equipment technology, and more specifically, to a cable winding and unwinding device for construction. Background Technology

[0002] Cable retraction devices are used for the orderly storage and release of cables. They are mainly used to achieve rapid and neat cable retrieval and release through automation, avoiding the inefficiency and messy cable problems caused by repeated manual pulling.

[0003] In related technologies, cable winding and unwinding devices consist of a steel reel, a support frame, and a transmission device. The working principle of the cable winding and unwinding device is that the transmission device drives the steel reel to rotate along its axis, and the cable winding mechanism sequentially winds the cable onto the steel reel in the axial direction, thereby achieving a fully automatic cable winding function.

[0004] In actual use, when the cable winding mechanism guides the cable to wind axially towards the steel reel, the cable is prone to friction with the discs at both ends of the steel reel, which leads to wear on the outer surface of the cable and damage to the insulation layer, thus affecting the subsequent use of the cable. Utility Model Content

[0005] In view of this, the present application provides a cable winding and unwinding device for construction to solve the problem that cables in the related art are prone to outer surface wear during winding.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] A cable winding and unwinding device for construction, comprising:

[0008] A steel pipe reel is rotatably mounted on the frame via bearings, with a disc fixedly mounted at each of its two axial ends and coaxially fixedly connected to the drive end of the first motor.

[0009] The cable laying mechanism includes a cable laying frame, a cable laying screw, a guide rod, and a cable laying device. The cable laying frame is mounted on the frame and located next to the steel cable reel. The cable laying screw is rotatably mounted on the cable laying screw. The guide rod is fixedly connected to the cable laying frame and parallel to the cable laying screw. The cable laying device is threadedly connected to the cable laying screw through a threaded hole and slidably connected to the guide rod through a sliding hole.

[0010] Two wire pulleys are symmetrically arranged on the inner surface of the cable tray and distributed along its length, with the plane containing the wires located inside the inner surface of the disc.

[0011] The second motor is located outside the cable tray and is coaxially fixed to the cable screw via a drive shaft.

[0012] In some possible implementations, the wire pulley includes a support and a fixed pulley rotatably connected thereto, which is bolted to the inner surface of the cable tray via the support.

[0013] In some possible implementations, the disc located at one end of the steel pipeline reel is a detachable connection structure.

[0014] In some possible implementations, both the disc and the steel pipe reel are provided with winding grooves in the radial direction.

[0015] In some possible implementations, a threader is welded to the bottom surface of the winding groove, the axis of the threading hole of which is parallel to the axis of the steel pipe disc, and a nylon cable tie is inserted into the threading hole.

[0016] In some possible implementations, the winding grooves on the steel pipe reel and the disc are in one-to-one correspondence, and the groove openings of the two are aligned to form a continuous bundling space.

[0017] The construction cable winding and unwinding device provided in this application embodiment has at least the following beneficial effects:

[0018] In the construction cable winding and unwinding device provided in this application embodiment, two guide pulleys are symmetrically installed on the inner surface of the cable tray, and the two guide pulleys are symmetrically distributed along the length direction of the cable tray. Furthermore, the guide planes of the two guide pulleys are located inside the inner surfaces of the two discs. Thus, when the cable follows the cable winding mechanism close to the inner surface of the discs, the cable is guided by the guide pulleys, thereby avoiding sliding friction with the inner surface of the discs. This structural design effectively protects the outer surface and insulation layer of the cable, thereby extending the cable's service life. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0037] like Figures 1-4As shown in the embodiment of this application, the construction cable winding device includes a frame 100, a steel cable reel 300, a cable laying mechanism, two conductor pulleys 800, and a second motor 510. The frame 100 is the main supporting structure of the cable winding device, and is welded from structural steel with anti-slip pads installed at its bottom. The first motor 200 is fixedly mounted on the side wall of the frame 100 using flange bolts. The steel cable reel 300 consists of a steel shaft and discs 310 fixedly mounted at both ends of its axial direction. The two ends of the steel shaft are rotatably supported on bearing seats of the frame 100 by deep groove ball bearings. Discs 310 for limiting movement are also installed at both ends of the steel shaft, and the outer diameter of each disc 310 is larger than the outer diameter of the steel shaft. In actual use, the cable can be wound around the steel shaft of the steel cable reel 300 and limited by the discs 310 at both ends. Furthermore, the drive shaft of the second motor 510 is coaxially and fixedly connected to the steel shaft of the steel cable reel 300 via a coupling.

[0038] The cable winding mechanism is a device used to evenly wind cables along the axial direction onto a steel shaft. The mechanism consists of a cable winding frame 400, a cable winding screw 500, a guiding rod 600, and a cable winding device 700. The cable winding frame 400 is a rectangular frame structure, fixed to the frame 100 by bolts. The cable winding frame 400 is located on the side of the steel cable reel 300. The two ends of the cable winding screw 500 are rotatably mounted on the bearing seats of the cable winding frame 400 via bearings. The guiding rod 600 is fixedly connected to the cable winding frame 400 and parallel to the cable winding screw 500. The cable winding device 700 is threadedly connected to the cable winding screw 500 through a pre-drilled threaded hole and slidably connected to the guiding rod 600 through a pre-drilled sliding hole. Therefore, the cable winding device 700 can move linearly along the guiding rod 600.

[0039] In this embodiment, two wire pulleys 800 are symmetrically arranged on the inner surface of the cable tray 400, and the two wire pulleys 800 are symmetrically distributed along the length of the cable tray 400. Specifically, the wire pulley 800 includes a support 810 and a fixed pulley 820 rotatably connected thereto, which is installed on the inner surface of the cable tray 400 by bolts through the support 810.

[0040] The radius of the arc-shaped wire groove of each wire pulley 800 is adapted to the diameter of the cable, and the plane of the wire pulley 800 for guiding the cable is located inside the inner surface of the disc 310. In this way, when the cable approaches the disc 310 via the cable guide 700, the cable will be guided by the wire pulley 800, preventing it from sliding and rubbing against the inner surface of the disc 310, thus avoiding damage to the outer surface of the cable.

[0041] In addition, a second motor 510 is fixedly connected to the outside of the cable tray 400. The drive shaft of the second motor 510 is coaxially fixed with the cable screw 500 and is used to drive the cable screw 500 to rotate, so as to realize the function of driving the cable tray 700 to reciprocate in a straight line.

[0042] The following is combined Figures 1-4 The working principle and working process of the construction cable winding and unwinding device provided in the embodiments of this application are described.

[0043] The first motor 200 is started to drive the steel cable reel 300 to rotate, and the second motor 510 is started to drive the cable guide screw 500 to rotate. The cable guide 700 moves linearly along the guide rod 600 under the drive of the cable guide screw 500. Preferably, the second motor 510 is a reversible motor to enable the cable guide 700 to perform reciprocating linear motion. Under the action of the cable guide 700, the cable is wound axially onto the steel shaft of the steel cable reel 300, and is limited by the discs 310 at both ends. When the cable approaches the inner surface of the disc 310, the cable is guided by the guide pulley 800 to avoid sliding contact with the inner surface of the disc 310. Simultaneously, the periodic reversal frequency of the second motor 510 can be set so that it reverses when the cable contacts the guide pulley 800, thereby achieving the winding and coiling process of the cable.

[0044] In the construction cable winding and unwinding device provided in this application embodiment, two conductor pulleys 800 are symmetrically installed on the inner surface of the cable tray 400, and the two conductor pulleys 800 are symmetrically distributed along the length direction of the cable tray 400. Furthermore, the conductor planes of the two conductor pulleys 800 are located inside the inner surfaces of the two discs 310. Thus, when the cable follows the cable winding mechanism close to the inner surface of the disc 310, the cable is guided by the conductor pulleys 800, thereby avoiding sliding friction with the inner surface of the disc 310. This structural design effectively protects the outer surface and insulation layer of the cable, thereby extending the cable's service life.

[0045] In some embodiments, such as Figure 6 As shown, the disc 310 located at one end of the steel cable reel 300 is a detachable connection structure. This allows the entire cable reel to be easily removed from the steel cable reel 300 by disassembling one end of the disc 310 after the cable is wound. This avoids the cable tangling or wear problems caused by pulling the cable from the end of the reel with a traditional fixed disc 310.

[0046] Based on the above embodiments, such as Figures 5-6As shown, both the disc 310 and the steel pipe reel 300 are provided with winding grooves 900 in the radial direction. A threader 320 is welded to the bottom surface of the winding groove 900, and the axis of its threading hole is parallel to the axis of the steel pipe disc 310. Nylon cable ties 910 are inserted into the threading hole. Furthermore, the winding grooves 900 on the steel pipe reel 300 and the disc 310 are one-to-one corresponding, and the groove openings of the two are aligned to form a continuous binding space.

[0047] In practical use, multiple nylon cable ties 910 can be threaded through the cable threading holes into the cable threader 320 and temporarily placed in the storage and binding space. After the cable is wound up on the steel shaft of the steel cable reel 300, the two ends of the nylon cable ties 910 can be tightened to bind the cable roll. Finally, the entire cable roll can be removed from the steel cable reel 300 by disassembling the disc 310 at one end.

[0048] The various embodiments or implementation methods described in this specification are presented in a progressive manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts between the embodiments can be referred to each other.

[0049] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," "some embodiments," etc., mentioned in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0050] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.

[0051] It should be readily understood that the terms “on,” “above,” and “on top of” in this disclosure should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on top of something” but also “on top of something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0052] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations (rotated 90 degrees or in other orientations), and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0053] As used herein, the term "substrate" refers to the material on which subsequent material layers are added. The substrate itself may be patterned. The material added on top of the substrate may be patterned or may remain unpatterned. Furthermore, the substrate may include a wide range of materials, such as silicon, germanium, gallium arsenide, indium phosphide, etc. Alternatively, the substrate may be made of a non-conductive material (e.g., glass, plastic, or sapphire wafers).

[0054] The term "layer" as used herein can refer to a portion of material comprising a region of thickness. A layer may extend over the entire underlying or overlying structure, or may have a extent smaller than that of the underlying or overlying structure. Furthermore, a layer may be a region of a homogeneous or non-homogeneous continuous structure, with a thickness less than that of the continuous structure. For example, a layer may be located between the top and bottom surfaces of the continuous structure, or between any pairs of lateral planes at the top and bottom surfaces. A layer may extend laterally, vertically, and / or along a tapered surface. A substrate may be a layer, and may include one or more layers, and / or may have one or more layers located on, above, and / or below it. A layer may include multiple layers. For example, an interconnect layer may include one or more conductor and contact layers (forming contacts, interconnects, and / or vias therein) and one or more dielectric layers.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
