Description

Technical Field

[0001] This application relates to the technical field of filler rope processing equipment, and in particular to a high-capacity long guide pulley frame. Background Technology

[0002] In the cable manufacturing process, filler rope is often used as a material to fill gaps in the cable. Conductor racks, as important equipment for storing and managing filler rope, are widely used in the power, communication, and other technical fields.

[0003] Currently, traditional guide reels typically employ a single-layer or multi-layer disc structure, using multiple parallel discs rotating on a frame to control the loading and unloading of the filler rope. However, with the expansion of project scale and the increasing complexity of working environments, traditional reel frames have gradually revealed shortcomings in filler rope management efficiency, space occupation, and interference resistance. In recent years, the industry has attempted to improve these issues by increasing the number of discs or optimizing the disc layout, but the effects have been limited, often leading to increased structural complexity and manufacturing costs.

[0004] Regarding the aforementioned technologies, the inventors believe that during the use of the aforementioned conductor frame, when the filler rope breaks, it is difficult to locate the broken filler rope and reconnect it. This leads to the filler ropes becoming entangled, increasing the difficulty of management. Summary of the Invention

[0005] In order to increase the storage capacity of filler rope and reduce management difficulty, this application provides a large-capacity long guide reel frame.

[0006] The high-capacity long guide wheel frame provided in this application adopts the following technical solution: A high-capacity long guide pulley frame includes a main rod, a connecting top plate, branch rods, and limiting members. The connecting top plate is connected to the top of the main rod. Several branch rods are arranged circumferentially along the edge of the connecting top plate. The connecting top plate is a circular plate. The branch rods are arranged along the radius of the connecting top plate. Several sets of limiting members are arranged along the length of the top surface of each branch rod. Each limiting member includes a clamping rod and a clamping roller. The clamping rod is vertically arranged on the branch rod. Each limiting member includes two clamping rods. The clamping roller is rotatably sleeved on the clamping rod. Several limiting members on each branch rod are arranged one-to-one along the circumference of the connecting top plate, and the corresponding limiting members are located on the same circumference.

[0007] By adopting the above technical solution, when storing the filler rope, the filler rope is clamped between two clamping rods in a corresponding limiting member along the circumference of the connecting top plate. The filler rope is wound several times between the corresponding limiting members. One filler rope is wound between each corresponding limiting member. Because there is a gap between adjacent limiting members, when one filler rope breaks, the broken end will not entangle with other filler ropes, which facilitates the management of the filler rope by the operator and thus improves the overall work efficiency. Through the cooperation of the main rod, connecting top plate, branch rod, and limiting members, the storage capacity of filler rope is increased and the management difficulty is reduced.

[0008] Optionally, the branch rod is provided with numerical markings along its length, and a plurality of the numerical markings are provided in one-to-one correspondence with a plurality of the limiting members.

[0009] By adopting the above technical solution, the setting of digital markers facilitates operators in locating the source of the breakage on the branch pole and performing rewiring operations based on the corresponding digital marker when the filler rope breaks. The filler rope passes between corresponding limiting pieces at the same digital marker position on the branch pole. Through the even distribution of the limiting pieces and the corresponding design of the digital markers, interference or knots in the filler ropes are avoided during storage and deployment.

[0010] Optionally, a mounting ring is coaxially disposed on the top surface of the connecting top plate, and a sliding ring groove is disposed along the circumferential direction on the outer ring wall of the mounting ring. One end of the branch rod is slidably disposed in the sliding ring groove of the mounting ring, and a locking member for fixing the branch rod is provided on the connecting top plate.

[0011] By adopting the above technical solution, the angle of the branch pole can be adjusted for different placement positions of the main pole, and the angle of the branch pole can be limited by locking components, so that the guide wheel frame can better adapt to the working environment and reduce the space occupied.

[0012] Optionally, the locking component includes a lifting plate, a limiting tooth ring, and a limiting tooth plate. The lifting plate is disposed above the mounting ring. The limiting tooth ring is connected to the bottom surface of the lifting plate and coaxially disposed with the connecting top plate. A lifting slide rod is vertically disposed on the top surface of the connecting top plate. The lifting plate is slidably connected to the lifting slide rod. A connecting member is disposed between the lifting plate and the connecting top plate. One limiting tooth plate is connected to the top surface of each branch rod. The limiting tooth plate is vertically disposed corresponding to the limiting tooth ring. The limiting tooth plate is provided with limiting teeth corresponding to the limiting tooth ring. In the natural state, the limiting tooth ring engages with the limiting teeth of the limiting tooth plate under the action of the elastic element.

[0013] By adopting the above technical solution, when it is necessary to adjust the angle of the branch rod, the lifting plate is pulled up, the limiting gear ring and the limiting gear plate separate from each other, the branch rod is rotated to a suitable angle, the lifting plate is released, the lifting plate moves downward under the action of the elastic element, the limiting gear ring and the limiting gear plate mesh with each other, thereby fixing the angle of the branch rod and reducing the possibility of the branch rod rotating on the connecting top plate during the operation.

[0014] Optionally, the mounting ring is provided with a top support assembly, which includes a connecting crossbar, a top support shaft, and a sliding rod. Several connecting crossbars are provided, positioned between two adjacent branch rods. The connecting crossbars are slidably connected to the mounting ring. A receiving cavity is provided inside the connecting crossbar along its length, and the sliding rod is slidably disposed within the receiving cavity. Several top support shafts are vertically arranged on the top surface of each sliding rod. Several connecting grooves are formed on the top surface of the connecting crossbar along its length, and these connecting grooves correspond one-to-one with and are slidably connected to several top support shafts. The top support shaft extends out of the connecting crossbar through the corresponding connecting groove. The connecting crossbar is provided with a driving component for driving the sliding rod to move along its length. Several top support shafts on the connecting crossbar are corresponding one-to-one with several limiting components along the circumference of the connecting top plate.

[0015] By adopting the above technical solution, during the winding of the filler rope, the filler rope is wrapped around the outside of the corresponding top support shaft. During storage, a driving component pushes the sliding rod away from the connecting top plate. Simultaneously, the sliding rod drives the top support shaft mounted on it to move synchronously away from the connecting top plate, and the top support shaft slides within the connecting groove of the corresponding tube. The top support shaft tensions the filler rope, reducing the possibility of the filler rope detaching from the branch rod during storage and unloading.

[0016] Optionally, a compression ring is coaxially connected to the bottom surface of the lifting plate, and a compression opening is provided on the connecting crossbar. The compression opening corresponds to the position of the compression ring in the vertical direction. The pressure opening is connected to the receiving cavity. An abutment block is connected to one end of the sliding rod near the connecting top plate. An abutment slope is provided on the side of the abutment block near the connecting top plate. The abutment slope is located at the top of the abutment block. A compression cone is provided circumferentially on the bottom surface of the compression ring. The compression cone corresponds to the abutment slope. A compression spring is provided at one end of the sliding rod away from the connecting top plate. One end of the compression spring is connected to the inner end wall of the receiving cavity. Under normal circumstances, the compression cone of the compression ring and the abutment slope of the abutment block are in contact with each other, and the compression spring is in a compressed state.

[0017] By adopting the above technical solution, when the lifting plate descends, the extrusion cone surface of the extrusion ring contacts the abutment slope of the abutment block. Under the extrusion action of the extrusion ring, the abutment block moves away from the connecting top plate, achieving synchronous drive of several top support shafts and tensioning the filling rope. When the lifting plate rises, the sliding rod moves towards the connecting top plate under the action of the extrusion spring, separating the top support shaft from the filling rope, facilitating the removal of the filling rope from the guide frame.

[0018] Optionally, the bottom surface of the branch rod is connected to a supporting inclined rod, the main rod is connected to a connecting ring, the peripheral wall of the mounting ring is provided with a supporting ring groove along the circumferential direction, and the bottom end of the supporting inclined rod is slidably disposed in the supporting ring groove.

[0019] By adopting the above technical solution, the support diagonal brace is inclined between the branch pole and the main pole, which realizes stable support for the branch pole, improves the connection stability between the branch pole and the main pole, and reduces the possibility of the branch pole breaking during use.

[0020] Optionally, the branch rod is hollow, and an extension slide rod is slidably provided at the end of the branch rod away from the connecting top plate. Several pairs of extension clamps are vertically and detachably provided on the section of the extension slide rod outside the branch rod. The branch rod is provided with a locking member for limiting the extension slide rod.

[0021] By adopting the above technical solution, the extension slide bar increases the wire storage capacity of the conductor rack, making it easier for operators to adjust the wire storage capacity according to actual needs and working environment.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the cooperation of the main rod, connecting top plate, branch rod and limiting parts, it can increase the storage capacity of filling rope and reduce the management difficulty; 2. The top support assembly reduces the possibility of the filler rope detaching from the branch pole during storage and deployment; 3. The installation of the supporting diagonal brace improves the connection stability between the branch bar and the main bar, and reduces the possibility of the branch bar breaking during use.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-8 This application will be further described in detail below. Embodiments of this application provide a high-capacity long guide reel frame, which has the effect of increasing the storage capacity of filler rope and reducing management difficulty.

[0033] Example 1 Reference Figure 1-3A high-capacity long guide wheel frame includes a main rod 1, branch rods 2, a connecting top plate 3, and an extension slide rod 4. The main rod 1 is vertically arranged, and the connecting top plate 3 is a circular plate, coaxially and horizontally connected to the top of the main rod 1. A mounting ring 5 is coaxially arranged on the top surface of the connecting top plate 3, and a sliding ring groove 51 is arranged along the circumferential direction on the outer peripheral wall of the mounting ring 5. Several branch rods 2 are arranged along the radial direction of the mounting ring 5, and a rotating roller 6 is connected to the end of the branch rod 2 near the mounting ring 5. The end of the branch rod 2 is located in the sliding ring groove 51, and the rotating roller 6 rotatably abuts against the inner ring wall of the sliding ring groove 51. The branch rod 2 is a square rod, and several limiting members are evenly spaced along its length on the top surface of the branch rod 2. The limiting members include clamping rods 7 and clamping rollers 8 rotatably sleeved on them. Each set of limiting members includes two clamping rods 7, and the two clamping rods 7 are arranged along the length direction of the branch rod 2. The limiting members on several branch rods 2 are arranged one-to-one along the circumference of the connecting top plate 3, and the limiting members in the corresponding circle form a group for storing filling rope. The clamping rods 7 are vertically arranged on the top surface of the branch rods 2, and the two clamping rollers 8 are spaced apart. Several numerical marks 9 are arranged on the branch rods 2 along their length direction, and the numerical marks 9 are arranged one-to-one with the limiting members, and are consistent with the numerical marks 9 corresponding to the limiting members in the same circle.

[0034] Reference Figure 2 and Figure 3 A connecting ring 10 is fixedly connected to the main rod 1, and a support ring groove 101 is provided along the circumferential direction on the outer ring wall of the connecting ring 10. A support rod 26 is inclinedly connected to the bottom surface of the branch rod 2, and a sliding arc plate 27 is connected to the bottom end of the support rod 26. The sliding arc plate 27 is slidably disposed in the support ring groove 101.

[0035] Reference Figure 3 A lifting plate 11, circular in shape, is arranged parallel and coaxially above the connecting top plate 3. A lifting slide rod 12, square in shape, is vertically and coaxially connected to the top surface of the connecting top plate 3, passing through and slidably connected to the lifting plate 11. A limiting block 13, detachably connected to the top of the lifting slide rod 12, is connected to the top of the lifting slide rod 12. A return spring 14 is fitted on the lifting slide rod 12, with one end connected to the bottom surface of the lifting plate 11 and the other end connected to the top surface of the connecting top plate 3.

[0036] Reference Figure 3 The bottom surface of the lifting plate 11 is coaxially connected to a limiting gear ring 15, and the top surface of the branch rod 2 is connected to a limiting gear plate 16. The limiting gear plate 16 is provided with limiting teeth corresponding to the limiting gear ring 15, and the limiting gear ring 15 is vertically aligned with the limiting gear plate 16. In its natural state, the limiting gear ring 15 is engaged with the limiting gear plate 16 under the action of the return spring 14.

[0037] Reference Figure 2 and Figure 4 The branch rod 2 is hollow, and an extension slide rod 4 is slidably installed at the end of each branch rod 2 away from the connecting top plate 3. A connecting screw hole 41 is provided on the bottom surface of the branch rod 2, and several fixing screw holes 21 are provided along the length of the bottom surface of the extension slide rod 4. The connecting screw hole 41 is connected to one of the fixing screw holes 21, and a bolt for fixing the position of the extension slide rod 4 is threaded into both the connecting screw hole 41 and the corresponding fixing screw hole 21. Several pairs of extension clamping rods 17 are vertically connected to the top surface of the extension slide rod 4 outside the branch rod 2. An extension roller 18 is rotatably sleeved on the extension clamping rod 17, and the bottom end of the extension clamping rod 17 is threadedly connected to the extension slide rod 4.

[0038] Reference Figure 1-3 When storing the filler rope, it is passed between the two clamping rollers 8 corresponding to a certain ring of limiters, and the filler rope is wound several times within the corresponding ring of limiters. The number of rings of limiters increases the storage capacity of the conductor frame. Furthermore, because there are gaps between adjacent limiters, the filler rope between adjacent rings is less likely to entangle, interfere, or knot during winding and unwinding, facilitating the management of the filler rope. Since each branch rod 2 has several corresponding number marks 9, during winding, the filler rope passes through the limiter above the same number mark 9 on each branch rod 2. The evenly distributed limiters and corresponding number marks 9 on the branch rod 2 prevent interference between filler ropes and also prevent difficulty in locating the source of a broken filler rope.

[0039] Reference Figure 2-4The angle of branch rod 2 can be adjusted according to different placement positions of the device. Lifting the lifting plate 11 upwards causes the return spring 14 to extend and accumulate elastic potential energy, separating the limiting gear ring 15 from several limiting gear plates 16, thus releasing the positional limitation on branch rod 2. Rotating branch rod 2 to a suitable angle allows the rotating roller 6 to slide in the sliding ring groove 51. After adjusting branch rod 2 to the appropriate angle, releasing the lifting plate 11 causes the limiting gear ring 15 on the bottom surface of the lifting plate 11 to engage with several limiting gear plates 16, fixing the angle of branch rod 2 and reducing the possibility of rotation during storage. Simultaneously with the rotation of branch rod 2, the sliding arc plate 27 slides in the support ring groove 101, and the support diagonal rod 26 provides inclined support between branch rod 2 and main rod 1, improving the structural stability between them, reducing the possibility of breakage, and enhancing the load-bearing capacity of branch rod 2. Because of the sliding connection between branch rod 2 and mounting ring 5, operators can easily adjust the angle of branch rod 2 according to actual needs, which helps the conductor frame better adapt to the working environment. To meet different wire storage requirements, the position of the end of extension slide rod 4 within branch rod 2 is adjusted, and bolts are used to pass through the corresponding fixing screw holes 21 and connecting screw holes 41 to fix the position of extension slide rod 4. Extension clamp rod 17 is connected to the section of the extension slide plate located outside branch rod 2. By adjusting the length of extension slide rod 4 extending beyond branch rod 2, the number of filler ropes wound can be increased, thereby increasing the wire storage capacity of the conductor frame.

[0040] The implementation principle of a large-capacity long guide reel frame in Embodiment 1 of this application is as follows: When storing filler rope, the filler rope is passed between two clamping rollers 8 corresponding to a certain circle of limiting members, and the filler rope is wound several times in the corresponding circle of limiting members. By setting several circles of limiting members, the storage capacity of the guide frame is increased. Through the design of the evenly distributed limiting members and corresponding number markings 9 on the branch rod 2, interference between filler ropes is avoided, and it is also prevented that if a filler rope breaks, it is not difficult to find the source of the breakage.

[0041] The angle of branch rod 2 can be adjusted to suit different placement positions of the device. The support rod 26 is inclined between branch rod 2 and main rod 1, improving the structural stability between them. To meet different wire storage requirements, the position of the end of the extension slide rod 4 within branch rod 2 is adjusted, and the extension clamp rod 17 is connected to the section of the extension slide rod located outside branch rod 2, thereby increasing the wire storage capacity of the conductor frame.

[0042] Example 2 Reference Figure 5-7The difference between Embodiment 2 and Embodiment 1 is that Embodiment 2 also includes a top support assembly 19. Several sets of top support assemblies 19 are provided on the mounting ring 5, with one set between each pair of adjacent branch rods 2. The top support assembly 19 includes a connecting crossbar 191, a connecting roller 192, a top support shaft 193, a top support roller 194, a sliding rod 195, an abutment block 196, and a compression ring 197. The connecting crossbar 191 is horizontally arranged along the radial direction of the mounting ring 5. One end of the connecting crossbar 191 near the mounting ring 5 is connected to the connecting roller 192. The connecting roller 192 is disposed in the sliding ring groove 51 of the mounting ring 5, and the connecting roller 192 rolls against the inner ring wall of the sliding ring groove 51. A receiving cavity 1911 is provided inside the connecting crossbar 191 along its length direction, and the sliding rod 195 is disposed in the receiving cavity 1911 along the length direction of the connecting crossbar 191.

[0043] Reference Figure 8 A guide block 20 is provided at the end of the receiving cavity 1911 away from the mounting ring 5. A guide groove 201 is provided at the end of the guide block 20 near the mounting ring 5. One end of the sliding rod 195 is slidably disposed in the guide groove 201 of the guide block 20. A compression spring 22 is provided in the guide groove 201 along the length direction of the connecting crossbar 191. One end of the compression spring 22 is connected to the inner end wall of the guide groove 201, and the other end is connected to the end of the sliding rod 195.

[0044] Referring to Figure 8, a plurality of sleeve rings 23 are fixedly sleeved on the sliding rod 195. These sleeve rings 23 correspond one-to-one with several sets of limiting members on the branch rod 2 along the circumference of the connecting top plate 3. Each sleeve ring 23 has a sliding ring 24 on the side furthest from the mounting ring 5, and the sliding ring 24 is slidably sleeved on the sliding rod 195. A top support spring 25 connects the sleeve ring 23 to the corresponding sliding ring 24. A top support shaft 193 is vertically connected to the top surface of each sliding ring 24. A plurality of connecting grooves 1912 are formed along the length of the connecting crossbar 191 on its top surface. These connecting grooves 1912 correspond one-to-one with and are slidably connected to the top support shafts 193. The top support shafts 193 extend out of the connecting crossbar 191 through the connecting grooves 1912 and are rotatably connected to top support rollers 194.

[0045] Reference Figure 7 and Figure 8The compression ring 197 is coaxially connected to the bottom surface of the lifting plate 11, and a compression cone surface 1971 is formed circumferentially on the bottom surface of the compression ring 197. A compression opening 1913 communicating with the receiving cavity 1911 is formed on the top surface of the connecting crossbar 191, and the compression opening 1913 is vertically aligned with the compression ring 197. The abutment block 196 is connected to the end of the sliding rod 195 near the mounting ring 5, and an abutment slope 1961 is formed on the top surface of the abutment block 196 near the mounting ring 5, which corresponds to the compression cone surface 1971. In the natural state, the compression cone surface 1971 of the compression ring 197 and the abutment slope 1961 of the abutment block 196 are in contact with each other under the action of the return spring 14, and the top support spring 25 is in a compressed state.

[0046] Reference Figure 6-8 During the winding process, the lifting plate 11 is raised. After winding and angle adjustment of the branch rod 2 are completed, the lifting plate 11 is released, and it moves downward under the action of the return spring 14. The compression ring 197 extends into the receiving cavity 1911 through the compression opening 1913. The compression cone surface 1971 contacts the abutting inclined surface 1961 and slides relative to each other. The sliding rod 195 moves away from the mounting ring 5 as the compression ring 197 compresses, and the top support spring 25 compresses and accumulates elastic potential energy. The top support shaft 193 moves away from the mounting ring 5 as the sliding rod 195 compresses, and the top support shaft 193 presses the filling rope from the inside, achieving tension of the filling rope and reducing the possibility of insufficient tension and separation of the filling rope from the limiting component during winding, unwinding, and storage. The top support spring 25 achieves elastic tension of the filling rope, reducing the possibility of breakage due to excessive tension of the filling rope during the top support process.

[0047] The implementation principle of a large-capacity long guide reel frame in Embodiment 2 of this application is as follows: The top support assembly 19 achieves tensioning of the filler rope, reducing the possibility of insufficient tension in the filler rope and separation from the limiting component during the winding, unwinding, and storage processes. The top support spring 25 achieves elastic tensioning of the filler rope, reducing the possibility of breakage due to excessive tension in the filler rope during the top support process.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
