Description

Technical Field

[0001] The invention relates to the technical field of continuously reelable pipe cables, and in particular to a retractable reel mechanism and a working method. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In the storage, transportation and construction of continuous reelable pipes and cables (including continuous oil pipes, composite flexible pipes, optical cables, electrical cables, etc.), the pipes and cables need to be reeled on storage and transportation reels. Usually, the diameter of the storage and transportation reel is 3-5 meters. The large diameter is to prevent the pipes and cables from being excessively bent when reeling, but it also brings inconvenience to the separate storage, transportation and recycling of the reel, thus affecting the transportation and recycling efficiency of the reel.

[0004] Patent CN214569823U discloses a reel with foldable and retractable reels. By providing a first reel and a second reel composed of a plurality of independent and foldable reels, each reel can be folded during transportation and storage, and the folded reel is stored in the cavity of the reel, which not only effectively reduces the volume of the reel, but also effectively protects the reel, and well solves the problems of inconvenience in transportation and storage of existing reels, and the reel is easily damaged during transportation and storage. However, when the reel is shrunk, each independent reel needs to be folded, which is inconvenient to operate. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a retractable reel mechanism, which is in an open state when in use. When it needs to be stored, transported and recycled separately, it is adjusted to a retracted state to facilitate storage, transportation and recycling. At the same time, the operation is convenient and quick when opening and retracting.

[0006] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0007] In the first aspect, an embodiment of the present invention provides a retractable reel mechanism, comprising two coaxially arranged flanges, a coaxial support tube is fixed between the centers of the two flanges, the support tube is slidably connected to two support seats, the support seats are connected to a two-way drive mechanism arranged between the two flanges to achieve synchronous movement toward or away from each other, the support seats are hinged to one end of a plurality of ribs arranged along the circumferential direction on the corresponding side, the other end of the ribs is hinged to a guard edge, the inner end of the guard edge is hinged to the flange, the guard edge is rotatably connected to a sliding member, a support rod is provided between the sliding members corresponding to each other on both sides, and the sliding member is slidably connected to the support rod.

[0008] Optionally, the bidirectional drive mechanism includes a bidirectional screw, one end of which is rotatably connected to the eccentric position of the flange on one side, and the other end is rotatably connected to the eccentric position of the flange on the other side. The bidirectional screw is threadedly connected to the two support seats to drive the two support seats to move toward or away from each other synchronously.

[0009] Optionally, the support seat adopts a tubular structure, which is sleeved on the outer circumference of the support tube and is slidably connected to the support tube.

[0010] Optionally, the support seat is provided with a plurality of hinge plates along the annular direction, the support seat is rotatably connected to one end of the rib via the hinge plates, and an ear plate is also fixed on the support seat, and the ear plate is connected to the bidirectional lead screw.

[0011] Optionally, the inner side surface of the flange is provided with a plurality of hinge seats along the circumferential direction, and the flange is rotatably connected to one end of the rib via the hinge seats.

[0012] Optionally, an ear plate is further provided on the outer surface of the support seat, and a threaded hole matching the bidirectional lead screw is provided on the ear plate, and the ear plate is threadedly connected to the bidirectional lead screw through the threaded hole.

[0013] Optionally, the support rod passes through the sliding member and is slidably connected to the sliding member.

[0014] Optionally, the outer periphery of the support rod is covered with a protective tube;

[0015] Furthermore, the protection tube is a PE heat shrink tube.

[0016] Optionally, the ribs, ribs and support rods are distributed at equal intervals along the circumferential direction of the flange.

[0017] In the second aspect, an embodiment of the present invention provides a working method of the retractable reel mechanism described in the first aspect: the two support seats are driven to move toward or away from each other synchronously through a bidirectional driving mechanism, and then the ribs are used to drive the side guard to swing. The swing of the side guard drives the support rod to move radially along the flange through a sliding member, thereby realizing the contraction and opening of the entire retractable reel mechanism.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The retractable reel mechanism of the present invention can realize the retraction and opening movement of the entire reel mechanism by driving the support base to make synchronous movements toward or away from each other through the two-way driving mechanism. When in use, the entire reel mechanism is in an open state. When separate storage, transportation and recycling are required, the entire reel mechanism is adjusted to a retracted state, thereby reducing the volume of the entire reel mechanism and facilitating separate storage, transportation and recycling. During operation, only the two-way drive needs to be operated, and there is no need to fold each reel sheet. The operation is simpler and the use is more convenient and quicker.

[0020] 2. In the retractable reel mechanism of the present invention, the outer periphery of the support tube is covered with a protective tube, which protects the tube and cable during use and avoids scratching of the tube and cable. BRIEF DESCRIPTION OF THE DRAWINGS

Specifically, as Figure 6-Figure 7 As shown, connecting plates 2-1 are provided at both ends of the support tube 2, which are fixedly connected to the flange plate through the connecting plates 2-1 and bolts. Two support seats 7 are slidably connected to the support tube 2, and the two support seats 7 can move toward or away from each other synchronously. The support seats 7 are connected to a two-way driving mechanism arranged between the two flange plates, and the two-way driving mechanism can drive the two support seats to move toward or away from each other synchronously.

[0050] In this embodiment, the two flanges 1 are respectively defined as a first flange and a second flange, the support seat 7 corresponding to the first flange is a first support seat, and the support seat corresponding to the second flange is a second support seat.

[0051] The support seat 7 is a tubular structure, and the support seat 7 is sleeved on the outer periphery of the support tube 2 and is slidably connected to the support tube.

[0052] The support seat 7 is hinged to one end of a plurality of ribs 6 which are equally spaced along the circumferential direction, and the other end of the ribs 6 is hinged to the retaining edge 3. Fig.18 As shown, hinge holes are provided at both ends of the rib 6, and the inner end of the retaining edge 3 is rotatably connected to the flange 1.

[0053] In this embodiment, the first support seat is hinged to one end of a plurality of ribs 6, the other end of the ribs 6 is hinged to the sidewall, the inner end of the sidewall 3 is rotatably connected to the first flange, the second support seat is hinged to one end of a plurality of ribs 6, the other end of the ribs 6 is hinged to the sidewall 3, and the inner end of the sidewall 3 is rotatably connected to the second flange.

[0054] In this embodiment, Figure 8 As shown, the first flange and the second flange include a body 1-1, the inner surface of the body is provided with a plurality of hinge seats 1-2 at equal intervals along the circumferential direction, and the inner end of the baffle is rotatably connected to the flange via the corresponding hinge seat.

[0055] Specific:

[0056] like Figure 9-10 , Fig.14 As shown, the outer tube surface of the support seat 7 is provided with a plurality of hinge plates 7-1 at equal intervals along the circumferential direction. The support seat is hinged to one end of the rib through the hinge plate 7-1 and the pin shaft, and the other end of the rib is hinged to the rib through the first hinge hole 3-1 and the pin shaft provided on the rib.

[0057] The retaining edge 3 is also rotatably connected to a sliding member 4 through a second hinge hole 3-2 and a pin. Figure 11-13 As shown, a hinge hole is provided on the fixed plate 4-1 on one side of the sliding member 4, and the sliding member 4 is rotatably connected to the retaining edge 3 through the hinge hole. The interior of the sliding member 4 has a cavity matching the support rod, and the support rod 5 passes through the sliding member 4 through the cavity. The sliding member 4 is slidably connected to the support rod 5. In this embodiment, the cross-section of the support rod 5 is square, and the internal space of the sliding member 4 is a square space, so the sliding member 4 adopts a rectangular tube structure.

[0058] In this embodiment, two ends of the same support rod 5 pass through the corresponding sliding members 4 on both sides respectively.

[0059] The bidirectional driving mechanism includes a bidirectional lead screw 8, which has a first lead screw section and a second lead screw section with opposite rotation directions, wherein the first lead screw section is threadedly connected to the first support seat, and the second lead screw section is threadedly connected to the second support seat.

[0060] Specifically, an ear plate 7-2 is provided on the outer tube surface of the first support seat and the second support seat, and a threaded hole matching the bidirectional lead screw is opened on the ear plate 7-2. The first support seat and the second support seat are connected to the bidirectional lead screw through the threaded hole. Rotating the bidirectional lead screw can drive the first support seat and the second support seat to move toward or away from each other synchronously.

[0061] One end of the bidirectional lead screw is rotatably connected to the first flange, and the other end is rotatably connected to the second flange. The bidirectional lead screw is arranged at one side of the support tube and parallel to the support tube.

[0062] In this embodiment, Fig.19 As shown, the two ends of the bidirectional screw are provided with connecting sections with a diameter smaller than the rest of the bidirectional screw, and the connecting sections are rotatably connected to the flange. A wrench hole is provided at the end of at least one connecting section to facilitate the staff to use a wrench to rotate the bidirectional screw.

[0063] The support rod 5 is a rod with a rectangular cross section, and a protective tube is wrapped around its outer circumference. Preferably, the protective tube is a PE heat shrink tube, which protects the pipe and cable during use and avoids scratches on the pipe and cable.

[0064] Further, such as Figure 15-17 As shown, the end and middle setting positions of the support rod are provided with limiting platforms 5 - 1 for limiting the sliding of the sliding members 4 on both sides thereof.

[0065] Example 2

[0066] This embodiment provides a working method of the retractable reel mechanism described in Embodiment 1:

[0067] When the reel mechanism needs to be used, an electric wrench is used to rotate the bidirectional screw, causing the two support seats to move away from each other. The support seats drive the retaining edges to swing outward through the ribs. At the same time, under the action of the sliding member, the support rod moves radially outward, thereby opening the reel mechanism for use.

[0068] When the reel mechanism is not in use and needs to be stored, transported or recycled, an electric wrench is used to rotate the bidirectional screw, and the two support seats move closer to each other. The support seats drive the retaining edges to swing inward through the ribs. At the same time, under the action of the sliding part, the support rod moves radially inward, thereby realizing the contraction of the reel mechanism.

[0069] By adopting the retractable reel mechanism of the present embodiment, when separate storage, transportation and recycling are required, the entire reel mechanism is adjusted to a retracted state, thereby reducing the volume of the entire reel mechanism and facilitating separate storage, transportation and recycling. During operation, it is only necessary to rotate the bidirectional screw without folding each reel piece, which makes the operation simpler and the use more convenient and quicker.

[0070] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
