Description
Technical Field
[0001] This invention relates to the field of cable reel technology, and more particularly to a detachable, retractable, circulating cable delivery reel. Background Technology
[0002] When cables are delivered, they need to be wound on delivery reels for transportation. The delivery reels with the cables wound on them are transported to the construction site by transport vehicles. The cable delivery reel is the core load-bearing tool in the production, transportation and laying process of wires and cables. It must have sufficient structural strength to withstand heavy winding, impact and stacking pressure, while ensuring smooth laying and no damage to the cable insulation layer.
[0003] In the prior art, patent CN209275843U discloses a cable reel that is easy to disassemble. It includes a winding drum, with an inner support frame fixedly installed inside. Limiting grooves are formed on both the left and right sides of the inner support frame, and fixing rods are inserted into the limiting grooves. Limiting discs that contact the winding drum are fixedly installed on the opposing surfaces of the two fixing rods. Fixing frames are fixedly installed at the top and bottom of the fixing rods. Two insertion holes are formed on the top and bottom walls of the inner cavity of the winding drum. A hollow cylinder is fixedly installed at the end of the fixing frame away from the fixing rod.
[0004] The above structure utilizes the overall separation of the limiting plate and the winding drum, but it does not effectively integrate the two functions of detachability and retraction. The detachable structure cannot achieve the shrinkage of the empty drum volume, and the retractable structure is difficult to balance convenient disassembly and assembly with long-term cyclic use. It is difficult to simultaneously meet the needs of improving on-site disassembly and assembly efficiency and extending the cycle life. Summary of the Invention
[0005] In view of this, the purpose of this invention is to propose a detachable, retractable, reusable cable delivery reel to solve the problem that retractable structures are difficult to balance convenient disassembly and long-term reusability, and difficult to simultaneously improve on-site disassembly efficiency and extend the service life.
[0006] To achieve the above objectives, the present invention provides a detachable, retractable, circulating wire and cable delivery reel, comprising a left side plate, a right side plate, and a cylindrical body disposed between the left side plate and the right side plate, and further comprising: A telescopic adjustment mechanism is provided between the left side plate and the right side plate, and the telescopic adjustment mechanism is used to adjust the axial distance between the left side plate and the right side plate. The interior of the cylinder is symmetrically arranged with multiple main load-bearing components along the circumference. These main load-bearing components are all located between the left side plate and the right side plate, and are used to maintain a fixed distance between the left side plate and the right side plate. The cylinder is assembled from multiple circumferentially distributed arc-shaped modules, and each arc-shaped module is detachably connected to the left and right side plates.
[0007] Preferably, the telescopic adjustment mechanism includes an inner telescopic tube, a middle telescopic tube, and an outer telescopic sleeve that slide and cooperate with each other, and one end of the inner telescopic tube and the outer telescopic sleeve is fixedly installed with a mounting plate that cooperates with the left side plate and the right side plate. Limiting structures are respectively provided on the inner telescopic tube, the middle telescopic tube and the outer telescopic sleeve. The limiting structures are used to lock and position each other when telescopically extended to the limit position.
[0008] Preferably, the limiting structure includes a rod fixedly installed at the bottom end of the inner telescopic tube and the middle telescopic tube. A lever and a retaining spring are movably installed on both sides of the bottom end of the lever. A protrusion is fixedly installed at the end of the lever, and the outside of the lever is provided with a slot to accommodate the movement of the retaining spring and a slot to restrict the movement of the retaining spring. Both the middle telescopic tube and the outer telescopic sleeve have insertion holes for accommodating the insertion rod inside, and both sides of the middle telescopic tube and the outer telescopic sleeve have sliding holes corresponding to the protrusion. Multiple sets of snap-fit holes are opened on one side of the sliding hole.
[0009] Preferably, one side of the multiple sets of snap-fit holes is rounded, and the multiple sets of snap-fit holes are equidistant. Both the upper and lower ends of the sliding hole are provided with stepped layers, which are used to drive the snap-fit spring sheet to move inside the slot and the snap-fit opening.
[0010] Preferably, the number of main load-bearing components is four, which are evenly and symmetrically arranged along the circumference of the cylinder; The main load-bearing component is a double-ended stud, with its two ends passing through the left and right side plates respectively and being locked in place by nuts.
[0011] Preferably, there are six arc-shaped modules, each with multiple operation holes for picking up the components. The central angle of each arc-shaped module is 60°. The splicing end faces of adjacent arc-shaped modules are provided with mutually cooperating positioning plates, and the adjacent positioning plates are locked together by bolts.
[0012] Preferably, the inner sides of both the left and right side plates are provided with annular positioning stops that mate with the ends of the arc-shaped module, and the depth of the annular positioning stops is 30-50mm.
[0013] Preferably, the inner sides of the left and right side plates are respectively provided with radial reinforcing ribs and circumferential reinforcing ribs, and the radial reinforcing ribs are evenly distributed along the circumferential direction.
[0014] The beneficial effects of this invention are: The entire system, through the setting of a telescopic adjustment mechanism and multiple main load-bearing components, achieves flexible adjustment and reliable fixation of the distance between the left and right side plates. The telescopic adjustment mechanism is responsible for adjusting the axial distance between the left and right side plates, so that the delivery tray can be adapted to cable specifications of different widths, making it highly versatile. Meanwhile, multiple main load-bearing components are symmetrically arranged along the circumference of the cylinder and independently bear the cable load. The outer cylinder is designed to be spliced together from multiple arc-shaped modules distributed along the circumference, and each arc-shaped module is detachably connected to the left and right side plates, so that the cylinder can be quickly disassembled into multiple independent arc-shaped modules, which are easy to stack and store after disassembly. The whole effectively integrates the two functions of detachability and shrinkability, which greatly improves the load-bearing reliability and service life of the structure.

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.
[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the detachable retractable circulating wire and cable delivery reel includes a left side plate 1, a right side plate 2, and a cylindrical body 3 disposed between the left side plate 1 and the right side plate 2, and also includes: A telescopic adjustment mechanism 4 is provided between the left side plate 1 and the right side plate 2. The telescopic adjustment mechanism 4 is used to adjust the axial distance between the left side plate 1 and the right side plate 2. Multiple main load-bearing components 5 are symmetrically arranged circumferentially inside the cylinder 3. The multiple main load-bearing components 5 are all set between the left side plate 1 and the right side plate 2. The main load-bearing components 5 are used to keep the distance between the left side plate 1 and the right side plate 2 fixed. The cylinder 3 is assembled from multiple circumferentially distributed arc-shaped modules 6, and each arc-shaped module 6 is detachably connected to the left side plate 1 and the right side plate 2.
[0022] In this embodiment, by setting up a telescopic adjustment mechanism 4 and multiple main load-bearing components 5, the flexible adjustment and reliable fixing of the distance between the left side plate 1 and the right side plate 2 are realized. The telescopic adjustment mechanism 4 is responsible for adjusting the axial distance between the left side plate 1 and the right side plate 2, so that the delivery tray can be adapted to cable specifications of different widths and has strong versatility. Meanwhile, multiple main load-bearing components 5 are symmetrically arranged around the circumference of the cylinder 3 and independently bear the cable load. The outer cylinder 3 is designed to be spliced together from multiple circumferentially distributed arc-shaped modules 6, and each arc-shaped module 6 is detachably connected to the left side plate 1 and the right side plate 2, so that the cylinder can be quickly disassembled into multiple independent arc-shaped modules 6. When the empty disc is recycled, each arc-shaped module 6 can be disassembled and stacked for storage. The overall design effectively integrates the two functions of detachability and retraction, which greatly improves the load-bearing reliability and service life of the structure.
[0023] As one implementation method, such as Figure 2 , Figure 5 and Figure 6 As shown, the telescopic adjustment mechanism 4 includes an inner telescopic tube 42, a middle telescopic tube 43 and an outer telescopic sleeve 44 that slide and cooperate with each other. One end of the inner telescopic tube 42 and the outer telescopic sleeve 44 is fixedly installed with a mounting plate 41 that cooperates with the left side plate 1 and the right side plate 2. Limiting structures 8 are provided on the inner telescopic tube 42, the middle telescopic tube 43 and the outer telescopic sleeve 44 respectively. The limiting structures 8 are used to lock and position each other when telescopically extended to the limit position.
[0024] In this embodiment, a three-layer sleeve nesting structure is adopted, consisting of an inner telescopic tube 42, a middle telescopic tube 43, and an outer telescopic sleeve 44 that slide and cooperate with each other. The structure is simple, the number of parts is small, and the processing difficulty is low. One end of the inner telescopic tube 42 and the outer telescopic sleeve 44 is fixedly installed with a mounting plate 41 that cooperates with the left side plate 1 and the right side plate 2, which ensures the connection rigidity and positioning accuracy between the telescopic mechanism and the left side plate 1 and the right side plate 2. At the same time, the inner telescopic tube 42, the middle telescopic tube 43 and the outer telescopic sleeve 44 are respectively provided with a limit structure 8, which can lock each other when telescopically extended to the designated position, ensuring the precise adjustment and reliable locking of the distance between the left side plate 1 and the right side plate 2.
[0025] As one implementation method, such as Figure 5 and Figure 6 As shown, the limiting structure 8 includes a rod 82 fixedly installed at the bottom of the inner telescopic tube 42 and the middle telescopic tube 43. A lever 81 and a retaining spring 83 are movably installed on both sides of the bottom end of the rod 82. A protrusion 87 is fixedly installed at the end of the lever 81, and the outside of the lever 81 is provided with a slot to accommodate the movement of the retaining spring 83 and a slot to restrict the movement of the retaining spring 83. Both the middle telescopic tube 43 and the outer telescopic sleeve 44 have insertion holes for accommodating the insertion rod 82, and both the middle telescopic tube 43 and the outer telescopic sleeve 44 have sliding holes 84 corresponding to the protrusion 87 on both sides. Multiple sets of snap-fit holes 85 are opened on one side of the sliding hole 84.
[0026] In this embodiment, the insertion rod 82 is fixedly installed at the bottom end of the inner telescopic tube 42 and the middle telescopic tube 43. The middle telescopic tube 43 and the outer telescopic sleeve 44 are provided with insertion holes to accommodate the insertion rod 82. When the inner telescopic tube 42, the middle telescopic tube 43 or the middle telescopic tube 43 and the outer telescopic sleeve 44 are pulled, the lever 81 drives the protrusion 87 to swing, smoothly sliding into and out of the locking hole 85. The spring plate 84 is used for elastic reset, and the spring plate 83 is buffered in the slot of the lever 81. When the lever 81 moves to the top, the step layer 86 at the top moves the spring plate 83 into the locking slot, so that the lever 81 moves downward at the maximum angle until it contacts the step layer 86 at the bottom. The spring plate 83 is re-locked into the slot outside the lever 81 and re-enters the sliding path of the locking hole 85, thereby achieving positioning. The operation is convenient and the positioning is reliable.
[0027] As one implementation method, such as Figure 6 As shown, one side of the multiple sets of snap-fit holes 85 is rounded, and the multiple sets of snap-fit holes 85 are equidistant. The upper and lower ends of the sliding hole 84 are provided with stepped layers 86, which are used to drive the snap-fit spring sheet 83 to move inside the slot and the snap-fit opening.
[0028] In this embodiment, by setting one side of multiple sets of snap-fit holes 85 to be rounded and evenly distributed, the protrusion 87 can smoothly slide into and out of the snap-fit holes 85 during the extension and retraction process, thereby reducing operating resistance and improving the smoothness of extension and retraction adjustment. Meanwhile, since both the upper and lower ends of the sliding hole 84 are provided with stepped layers 86, the stepped layers 86 are used to drive the retaining spring 83 to switch between the slot and the latch of the lever 81. When the lever 81 drives the protrusion 87 to swing, the retaining spring 83 is buffered in the slot of the lever 81. When the lever 81 moves to the top, the stepped layer 86 at the top is used to move the retaining spring 83 into the latch, so that the lever 81 moves downward at the maximum angle until it contacts the stepped layer 86 at the bottom. The retaining spring 83 is then re-engaged into the slot outside the lever 81 and re-enters the sliding path of the latching hole 85, realizing the automatic switching between the locking and unlocking states, further improving the ease of operation and locking reliability of the limit structure 8.
[0029] As one implementation method, such as Figure 1 , Figure 2 and Figure 3 As shown, there are four main load-bearing components 5, which are evenly and symmetrically arranged around the circumference of the cylinder 3. The main load-bearing component 5 is a double-ended stud, with both ends of the stud passing through the left side plate 1 and the right side plate 2 respectively and being locked in place by nuts.
[0030] In this embodiment, since there are four main load-bearing components 5, they are evenly and symmetrically arranged around the cylinder 3, so that the cable load is evenly distributed in the circumferential direction, avoiding local stress concentration caused by eccentric load. The main load-bearing components 5 adopt double-headed studs, with both ends passing through the left side plate 1 and the right side plate 2 respectively and locked and fixed by nuts, forming a rigid main support frame, which is easy to disassemble.
[0031] As one implementation method, such as Figure 4 As shown, there are six arc-shaped modules 6. Each arc-shaped module 6 has multiple operation holes for picking up the parts. The central angle of each arc-shaped module 6 is 60°. The splicing end faces of adjacent arc-shaped modules 6 are provided with mutually cooperating positioning plates 61. The adjacent positioning plates 61 are locked together by bolts.
[0032] In this embodiment, since there are six arc-shaped modules 6, and the central angle of each arc-shaped module 6 is 60°, the weight of a single module is controlled within 30kg, which fully supports manual handling and installation. Each of the adjacent arc-shaped modules 6 has a matching positioning plate 61 on its splicing end face. The adjacent positioning plates 61 are locked together by bolts, which ensures high splicing accuracy and sufficient connection rigidity, thus guaranteeing the roundness and structural integrity of the cylinder 3 under full load. When a single arc-shaped module 6 is damaged, only the corresponding module needs to be replaced, without scrapping the entire assembly, which reduces maintenance costs.
[0033] As one implementation method, such as Figure 1 , Figure 2 As shown, the inner sides of both the left side plate 1 and the right side plate 2 are provided with annular positioning stops 7 that cooperate with the ends of the arc-shaped module 6. The depth of the annular positioning stops 7 is 30-50mm.
[0034] In this embodiment, annular positioning stops 7 are provided on the inner sides of both the left side plate 1 and the right side plate 2 to cooperate with the ends of the arc-shaped module 6. The depth of the annular positioning stops 7 is 30-50mm. When the arc-shaped module 6 is spliced, the ends can be directly inserted into the annular positioning stops 7 to achieve quick and accurate positioning without repeated hole adjustments, which greatly improves the assembly efficiency of the cylinder. At the same time, the annular positioning stops 7 can effectively constrain the radial displacement of the arc-shaped module 6 under full load conditions, enhancing the connection rigidity and deformation resistance between the cylinder 3 and the left side plate 1 and the right side plate 2.
[0035] As one implementation method, such as Figure 1 , Figure 2 and Figure 3 As shown, radial stiffeners and circumferential stiffeners are respectively provided on the inner sides of the left side plate 1 and the right side plate 2, with the radial stiffeners being evenly distributed along the circumferential direction.
[0036] In this embodiment, radial stiffeners and circumferential stiffeners are respectively provided on the inner sides of the left side plate 1 and the right side plate 2. The radial stiffeners are evenly distributed along the circumference to form a mesh-like stiffening structure. This structure effectively improves the stiffness and bending resistance while controlling the self-weight of the left side plate 1 and the right side plate 2, avoiding excessive deformation of the left side plate 1 and the right side plate 2 under full load, and ensuring the structural stability and safety of the delivery pallet during transportation and stacking.
[0037] As one implementation method, such as Figure 7 As shown, this specification discloses a disassembly fixture for assisting in the compression of the left side plate 1 and the right side plate 2. The disassembly fixture includes a base plate 9 and a fixed tray 10 fixedly installed on the base plate 9. A rail 12 is also fixedly installed on the base plate 9, and a sliding tray 11 is slidably installed on the rail 12. The left side plate 1 and the right side plate 2 correspond to the fixed tray 10 and the sliding tray 11, respectively. A screw 13 runs through the interior of the left side plate 1 and the right side plate 2. A nut seat 14 is threaded onto the outside of the screw 13, and a rectangular block 15 runs through the outside of the screw 13. The rectangular block 15 abuts against one side of the left side plate 1. A handwheel 16 is fixedly installed at one end of the screw 13. A fastening nut and a ring are provided between the handwheel 16 and the rectangular block 15.
[0038] When the shaft disc needs to be compressed, release the limiting structure 8 between the inner telescopic tube 42, the middle telescopic tube 43 and the outer telescopic sleeve 44 in the telescopic adjustment mechanism 4 in advance, place the left side plate 1 and the right side plate 2 of the shaft disc to be compressed on the fixed tray 10 and the sliding tray 11 respectively, ensuring that the left side plate 1 corresponds to the fixed tray 10 and the right side plate 2 corresponds to the sliding tray 11, and then rotate the handwheel 16 clockwise; The screw 13 is rotated by the handwheel 16, and the nut seat 14 moves linearly along the axis of the screw 13. Since the right side plate 2 corresponds to the sliding tray 11, the nut seat 14 will directly push the right side plate 2, thereby compressing the sliding tray 11 and moving it towards the fixed tray 10. The telescopic adjustment mechanism 4 is compressed internally to achieve rapid compression.
