Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, specifically to a reel-type cable laying device. Background Technology

[0002] In fields such as power engineering, elevator installation, and industrial equipment wiring, the laying of cables and heavy-duty wires (such as elevator steel wires and cables) is a critical construction step, and its efficiency and safety directly affect the overall project progress and the personal safety of on-site workers. Currently, commonly used cable laying tools on construction sites have many technical defects: traditional, simple on-site cable laying devices require multiple people to push the cable reel, which not only consumes a lot of manpower but also easily causes the cable reel to shift due to uneven force during laying; bracket-type cable laying devices, due to insufficient structural stability at the connection between the bracket and the crossbar, are prone to falling or tipping over when carrying heavy wires, posing serious safety hazards.

[0003] For example, patent CN205583543U discloses a large-scale reel cable laying device based on hydraulics, including a pair of identical reel support frames. Each reel support frame includes a base, guide rails, and a lifting frame. At least two guide rails are provided on the base, and the guide rails are vertically fixed to the base. The lifting frame has guide grooves that fit onto the guide rails. A hydraulic rod for driving the lifting frame to rise and fall is installed on the base. This invention is widely applicable to reel cable laying, eliminating the need for forklifts during the laying process, reducing the need for traditional reel cable support fabrication, simplifying the cable laying process, reducing the use of machinery during cable laying, and significantly saving cable laying costs.

[0004] However, the aforementioned hydraulic-based large-scale reel cable laying device, which uses a symmetrical fixing structure of "a pair of reel support frames," can achieve reel support, but lacks flexibility in positioning and adjusting the reels. When laying cable reels of different diameters, it is necessary to frequently disassemble and adjust the spacing of the support frames, which is cumbersome and time-consuming. It is difficult to adapt to the diverse cable laying needs of construction sites, and there is no dedicated locking mechanism. If the work needs to be temporarily suspended during cable laying (such as adjusting the cable route or connecting cable joints), the reels are prone to accidental rotation due to their own weight or external force, resulting in loose stacking or displacement of the cables. This not only affects the laying accuracy but may also cause safety risks such as cable entanglement and personnel tripping. Utility Model Content

[0005] The purpose of this utility model is to provide a reel-type cable laying device to solve the problems mentioned in the background art, such as insufficient flexibility in positioning and adjusting the reel due to the symmetrical fixed structure of "a pair of reel support frames", the need to frequently disassemble and adjust the spacing of the support frames for cables of different diameters and specifications, cumbersome operation, and the lack of a special locking mechanism, which causes the reel to rotate accidentally due to its own weight or external force when the cable laying is temporarily suspended, thereby causing the cable to slack and stack, shift, and affect the laying accuracy.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A reel-type cable laying device includes: a carrying cylinder, a rotating shaft fixedly installed inside the carrying cylinder, a placement disc rotatably installed at the upper end of the outer surface of the rotating shaft, the lower surface of the placement disc simultaneously abutting the upper ends of multiple sets of first rollers, each set of first rollers being rotatably installed in a first U-shaped frame, the multiple sets of first U-shaped frames being fixedly installed in an equidistant ring on the upper surface of the carrying cylinder, and a toothed ring being embeddedly fixedly installed on the lower surface of the outer ring of the placement disc, the toothed ring being capable of engaging with a vertically sliding locking mechanism, the locking mechanism being rotatably installed at the bottom of the carrying cylinder.

[0007] Preferably, the locking mechanism includes a connecting ring, which is located inside the bearing cylinder and simultaneously slidably mounted on the outer surface of multiple sets of guide rails. The guide rails are fixedly mounted on the upper surface of the "spokes" inside the bearing cylinder. The upper surface of the connecting ring is fixedly mounted with a tooth, which can engage with a toothed ring by sliding the connecting ring vertically upward.

[0008] Preferably, a lifting plate is fixedly installed on the lower surface of the connecting ring. The lifting plate is in the shape of an annular triangular inclined plane. The lifting plate is located between the "spokes" of every two sets of bearing cylinders, and its lower surface is in contact with the second roller. The second roller is rotatably installed in the second U-shaped frame. The second U-shaped frame is fixedly installed on the outer ring of the upper surface of the connecting plate. The connecting plate is rotatably installed at the bottom of the bearing cylinder.

[0009] Preferably, each set of the second U-shaped frame is also located between every two sets of "spokes" of the bearing cylinder.

[0010] Preferably, a push-pull handle is fixedly installed at one end of the outer surface of the connecting plate. The push-pull handle slides out from the sliding bar opening in a damped manner. The sliding bar opening is located on the outer surface of the bearing cylinder.

[0011] Preferably, the connecting plate is able to drive the second roller to roll and press against the inclined sliding surface of the lifting plate by pushing the push-pull handle, thereby achieving the vertical raising and lowering of the connecting ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The cable reel installation method, which combines "hoisting and installation + rotating shaft positioning" with rolling friction transmission achieved by the annularly distributed first roller, not only significantly reduces the manpower required for cable laying, but also adapts to cable reels of different diameters without structural adjustments, improving operational flexibility and efficiency. Furthermore, the locking mechanism driven by the push-pull handle allows for precise engagement / disengagement of the teeth and rings through simple operation, quickly locking the placement tray during temporary work stoppages. This effectively prevents cable slack stacking, displacement, and tripping risks caused by accidental rotation of the cable reel. Balancing operational efficiency, adaptability, and safety, this method provides reliable protection for cable laying in scenarios such as power engineering and elevator installation.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 This embodiment provides the following technical solution: like Figures 1-2As shown, a reel-type cable laying device includes: a bearing cylinder 1, a rotating shaft 102 fixedly installed inside the bearing cylinder 1, a placement disc 103 rotatably installed at the upper end of the outer surface of the rotating shaft 102, the lower surface of the placement disc 103 simultaneously abutting the upper ends of multiple sets of first rollers 105, each set of first rollers 105 being rotatably installed inside a first U-shaped frame 104, the multiple sets of first U-shaped frames 104 being fixedly installed in an equidistant ring on the upper surface of the bearing cylinder 1, and a toothed ring 106 being fixedly installed in an embedded manner on the lower surface of the outer ring of the placement disc 103, the toothed ring 106 being able to engage with a vertically sliding locking mechanism 2, the locking mechanism 2 being rotatably installed at the bottom inside the bearing cylinder 1.

[0017] Through the design of the bearing cylinder 1, rotating shaft 102, placement tray 103, first rollers 105, toothed ring 106, guide rail 107, and locking mechanism 2, the cable shaft is laid flat during use, and then hoisted and placed on the upper surface of the placement tray 103 and threaded onto the outer surface of the rotating shaft 102. The placement tray 103 provides stable support for the cable shaft. Since the placement tray 103 is rotatably mounted on the upper part of the outer surface of the rotating shaft 102, and its lower surface simultaneously abuts against the upper ends of multiple sets of equidistantly distributed first rollers 105, when the operator pulls the free end of the cable for laying, the cable shaft will drive the placement tray 103 to rotate synchronously around the rotating shaft 102. During this process, the first rollers 105 will roll synchronously with the rotation of the placement tray 103, replacing sliding friction with rolling friction, greatly reducing the resistance when the placement tray 103 rotates, reducing labor consumption. At the same time, the annularly distributed first rollers 105 can always provide uniform support to the placement tray 103, preventing the placement tray 103 from becoming unstable. 3. Due to uneven force, tilting or shifting may occur. Since there is no need to adjust the device structure for cable reels of different diameters, the placement tray 103 and the first roller 105 provide uniform support, accommodating the laying needs of cable reels of various diameters. When laying operations need to be temporarily paused, such as to adjust cable routing or connect cable joints, the locking mechanism 2, which is rotatably installed at the bottom of the bearing cylinder 1, can be operated to slide vertically upwards and engage with the toothed ring 106 embedded in the lower surface of the outer ring of the placement tray 103. The engagement between the toothed ring 106 and the locking mechanism 2 restricts the rotation of the placement tray 103, thereby preventing accidental rotation of the cable reel due to its own weight or external force. This avoids problems such as cable slack stacking and shifting, ensuring operational safety and laying accuracy. When laying operations need to resume, simply pull the locking mechanism 2 to release the engagement with the toothed ring 106, and the placement tray 103 can rotate freely around the rotating shaft 102 again to continue cable laying operations.

[0018] like Figures 3-4As shown, the locking mechanism 2 includes a connecting ring 201, which is located inside the bearing cylinder 1 and simultaneously slidably mounted on the outer surface of multiple sets of guide rail rods 107. The guide rail rods 107 are fixedly mounted on the upper surface of the "spokes" inside the bearing cylinder 1. A tooth 202 is fixedly mounted on the upper surface of the connecting ring 201, and the tooth 202 can engage with the toothed ring 106 by the vertical upward sliding of the connecting ring 201. A lifting plate 203 is fixedly installed on the lower surface of the connecting ring 201. The lifting plate 203 is in the shape of an annular triangular inclined plane. The lifting plate 203 is located between the "spokes" of every two sets of bearing cylinders 1, and its lower surface is in contact with the second roller 207. The second roller 207 is rotatably installed in the second U-shaped frame 205. The second U-shaped frame 205 is fixedly installed on the outer ring of the upper surface of the connecting plate 204. The connecting plate 204 is rotatably installed at the bottom of the bearing cylinder 1. Each set of second U-shaped frames 205 is also located between every two sets of "spokes" of the bearing cylinder 1.

[0019] Among them, a push-pull handle 206 is fixedly installed on one end of the outer surface of the connecting plate 204. The push-pull handle 206 slides out from the sliding bar opening 101 in a damped manner. The sliding bar opening 101 is opened on the outer surface of the bearing cylinder 1, so that the connecting plate 204 can drive the second roller 207 to roll and press the inclined sliding surface of the lifting plate 203 through the push of the push-pull handle 206 to realize the vertical rise and fall of the connecting ring 201.

[0020] Through the design of the connecting ring 201, the serrated tooth 202, the lifting plate 203, the connecting plate 204, the push-pull handle 206, and the second roller 207, when the cable laying operation needs to be temporarily suspended and the placement plate 103 needs to be locked, the operator can push the push-pull handle 206 fixed to one end of the outer surface of the connecting plate 204, causing the push-pull handle 206 to slide along the sliding strip opening 101 on the outer surface of the bearing cylinder 1 in a damped manner, thereby driving the connecting plate 204, which is rotatably installed at the bottom of the bearing cylinder 1, to rotate synchronously. Since the second U-shaped frame 205 fixedly installed on the outer ring of the upper surface of the connecting plate 204 is located between every two sets of "spokes" of the bearing cylinder 1... Between them, and the second roller 207 rotatably installed inside the second U-shaped frame 205, contacts the lower surface of the lifting plate 203 fixedly installed on the lower surface of the connecting ring 201. When the connecting plate 204 rotates, it will drive the second roller 207 to make a circular motion around the center of the connecting plate 204. At the same time, the second roller 207 rolls on the annular triangular inclined surface of the lifting plate 203 and gradually presses against the inclined surface. As the pressing effect of the second roller 207 on the inclined surface of the lifting plate 203 increases, the lifting plate 203 will drive the connecting ring 201 fixed thereto to slide vertically upward along the outer surface of the guide rail rods 107 fixed on the upper surface of the "spokes" inside the bearing cylinder 1. The guide rail 107 guides and limits the sliding of the connecting ring 201, preventing it from shifting during its upward movement. When the connecting ring 201 slides to the preset position, the protruding teeth 202 fixedly mounted on the upper surface of the connecting ring 201 precisely mesh with the toothed ring 106 embedded in the lower surface of the outer ring of the placement tray 103. The meshing of the protruding teeth 202 and the toothed ring 106 restricts the rotation of the placement tray 103, thus achieving the rotation locking function of the placement tray 103. When it is necessary to release the lock and resume the laying operation, the operator pulls the push-pull handle 206 in the opposite direction, causing the connecting tray 204 to rotate in the opposite direction, so that the second Roller 207 rolls in the opposite direction along the inclined surface of lifting plate 203, and the pressing effect gradually weakens. Under its own gravity, connecting ring 201 slides vertically down guide rail 107. The tooth 202 disengages from the toothed ring 106, and the placement tray 103 can automatically return to a free rotation state. By locking the placement tray 103, the accidental rotation of the cable shaft due to its own gravity or external force is prevented from being touched, thereby preventing the cable from slack stacking and deviation, and preventing the cable from deviating from the preset laying path. At the same time, it eliminates the risk of personnel tripping due to the random rolling of the cable, and provides reliable protection for the personal safety of on-site workers and the integrity of the cable.

[0021] Based on the above technical solution, the working steps of this solution are summarized as follows: During use, the cable reel is laid flat and then hoisted onto the upper surface of the placement tray 103 and threaded onto the outer surface of the rotating shaft 102. The placement tray 103 provides stable support for the cable reel. Since the placement tray 103 is rotatably mounted on the upper surface of the outer surface of the rotating shaft 102, and its lower surface simultaneously contacts the upper ends of multiple sets of equidistantly distributed first rollers 105, when the operator pulls the free end of the cable for laying, the cable reel will drive the placement tray 103 to rotate synchronously around the rotating shaft 102. During this process, the first rollers 105 will roll synchronously with the rotation of the placement tray 103, using rolling friction to replace... Sliding friction significantly reduces the resistance when the placement disc 103 rotates, reducing manpower consumption. When the laying operation needs to be temporarily suspended, the operator can push the push-pull handle 206 fixed to one end of the outer surface of the connecting disc 204, causing the push-pull handle 206 to slide along the sliding strip opening 101 on the outer surface of the bearing cylinder 1 in a damped manner, thereby driving the connecting disc 204, which is rotatably installed at the bottom of the bearing cylinder 1, to rotate synchronously. Since the second U-shaped frame 205 fixedly installed on the outer ring of the upper surface of the connecting disc 204 is located between every two sets of "spokes" of the bearing cylinder 1, and the second roller 207 rotatably installed inside the second U-shaped frame 205 is in contact with the lower surface of the lifting plate 203 fixedly installed on the lower surface of the connecting ring 201, the second roller 207 rotatably installed inside the second U-shaped frame 205 is in contact with the lower surface of the lifting plate 203 fixedly installed on the lower surface of the connecting ring 201. When the connecting plate 204 rotates, it drives the second roller 207 to move in a circular motion around the center of the connecting plate 204. At the same time, the second roller 207 rolls on the annular triangular inclined surface of the lifting plate 203 and gradually presses against the inclined surface. As the pressing force of the second roller 207 on the inclined surface of the lifting plate 203 increases, the lifting plate 203 will drive the connecting ring 201 fixed thereto to slide vertically upward along the outer surface of the guide rail rods 107 fixed on the upper surface of the "spokes" inside the bearing cylinder 1. The guide rail rods 107 guide and limit the sliding of the connecting ring 201, preventing the connecting ring 201 from deviating during the upward sliding process. When the connecting ring 201 slides to the preset position, it is fixedly installed on the connecting ring 201. The protruding teeth 202 on the upper surface of the placement tray 103 precisely mesh with the toothed ring 106 embedded in the lower surface of the outer ring of the placement tray 103. The rotation of the placement tray 103 is restricted by the meshing of the teeth of the protruding teeth 202 and the toothed ring 106, thus realizing the rotation locking function of the placement tray 103. When it is necessary to release the lock and resume the laying operation, the operator pulls the push handle 206 in the opposite direction, which drives the connecting tray 204 to rotate in the opposite direction, so that the second roller 207 rolls in the opposite direction along the inclined surface of the lifting plate 203. The pressing effect gradually weakens, and the connecting ring 201 slides down vertically along the guide rail 107 under its own gravity. The protruding teeth 202 and the toothed ring 106 disengage, and the placement tray 103 can automatically resume its free rotation state.

[0022] In summary, this solution can adapt to cable reels of different diameters without frequent structural adjustments, reducing equipment costs and storage pressure. At the same time, the strong protection of the locking mechanism 2 completely eliminates cable slack stacking and solves the problem of accidental rotation of cable reels when temporarily suspending operations. This not only ensures the personal safety of operators and the integrity of cables, but also improves laying accuracy.
