Description

Technical Field

[0001] This invention relates to the field of cable production equipment technology, specifically to a cable reel lifting device. Background Technology

[0002] In the cable manufacturing industry, after the cables are produced, they usually need to be regularly wound onto cable reels for easy storage, transportation, and subsequent use. Before the winding operation, the empty cable reel must be installed on the winding expansion shaft of the winding equipment. The expansion shaft tightens the shaft hole of the cable reel and drives it to rotate, thereby completing the cable winding process.

[0003] Because cable reels are quite heavy and are often placed off the ground during installation, specialized lifting equipment is needed to lift them from the ground before moving and installing them onto the expansion shaft. Currently, the commonly used lifting equipment is a forklift-like structure with two sets of parallel support plates. In operation, the operator first manually moves the cable reel to the lifting platform and pushes it between the two support plates, ensuring its axis is parallel to the plates. Then, the lifting platform raises the cable reel to approximately the same height as the expansion shaft. Next, by repeatedly moving the lifting platform or manually pushing and pulling the cable reel, its position is continuously adjusted until the expansion shaft and the cable reel's shaft hole are aligned. Finally, the cable reel is pushed axially to fit onto the expansion shaft and locked in place.

[0004] The existing operating methods described above have at least the following obvious shortcomings: First, transferring the cable reel to the elevator mainly relies on manual handling and pushing, which is extremely labor-intensive. Especially for large-sized and heavy cable reels, the handling process is not only time-consuming and labor-intensive, but also poses significant safety hazards. Second, after the cable reel is lifted on the elevator, its spatial posture and position still need to be manually adjusted repeatedly to achieve precise alignment between the winding expansion shaft and the shaft hole. However, due to the limited movement accuracy and flexibility of the elevator itself, this alignment operation is very difficult and often requires multiple attempts. The entire process is time-consuming, which seriously reduces the installation efficiency of the cable reel and thus affects the continuous operation capability of the entire production line. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a cable reel lifting device, thereby reducing labor intensity and improving the convenience, alignment accuracy, and efficiency of cable reel installation.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A cable reel lifting device includes a base, and the device further includes:

[0008] The frame includes two sets of vertical plates and one set of horizontal plates. The two sets of vertical plates are fixed longitudinally to the base, and the horizontal plate is fixed to the top of the two sets of vertical plates. A reversing groove is provided on the inner side of the vertical plate. The reversing groove is composed of a lower arc segment and an upper vertical segment.

[0009] The lifting frame includes a set of base plates and two sets of guide plates. A telescopic component is installed on the base, and its output end is fixedly connected to the base plate. The two sets of guide plates are symmetrically installed on the base plate and are slidably connected along the vertical plate. A connecting plate is provided at the bottom end of the guide plate.

[0010] The pallet includes a set of curved pallets and two sets of support plates. The two sets of support plates are symmetrically installed on the pallets, and guide rollers are installed on the support plates. The guide rollers move along the reversing groove. Two sets of rotating shafts are symmetrically arranged on the pallets and are rotatably mounted on the connecting plate.

[0011] A positioning mechanism is provided on the side of the tray for positioning the cable reel.

[0012] As a further aspect of the present invention: a plurality of sliding rollers and a plurality of supporting rollers are respectively installed on the guide plate, and a longitudinal vertical groove is opened on the outer side of the vertical plate, the sliding rollers abut against the side of the vertical groove, and the supporting rollers abut against the inner surface of the vertical groove.

[0013] As a further embodiment of the present invention: the positioning mechanism includes a slide, a mounting frame, positioning posts, and a mounting plate. The slide is fixed to the side of the support plate, the mounting frame is slidably mounted on the slide, and the mounting frame is provided with a plurality of positioning posts for positioning the cable reel. The side of the support plate is also provided with a mounting plate. The pinion and the gear are coaxially mounted on the mounting plate. A main gear plate is installed through the side of the support plate. The main gear plate meshes with the pinion. An elastic element is connected between the main gear plate and the side of the support plate through a baffle. One end of the main gear plate located inside the support plate is wedge-shaped. A secondary gear plate is provided at the bottom of the mounting frame. The secondary gear plate passes through the slide and meshes with the gear.

[0014] As a further embodiment of the present invention: the mounting frame is provided with a plurality of compartments, a sliding plate is slidably installed in the compartments, a fixing cylinder is provided on one side of the sliding plate, the positioning post is slidably installed inside the sliding plate and the fixing cylinder, and an elastic element is connected between the end of the positioning post and the end of the fixing cylinder.

[0015] As a further aspect of the present invention: the tray is bent, and when the cable reel is placed on the tray, a diameter on the end face of the cable reel intersects with the bending line of the tray, and the line connecting the centers of the end faces of several positioning posts coincides with this diameter.

[0016] As a further aspect of the present invention: a positioning sensor is provided at one end of the positioning column via a connecting rod, the connecting rod passing through the end of the fixed cylinder, and a positioning sensor is installed on the base via a support rod. The positioning sensor and the positioning sensor work together to determine whether the cable reel has reached the correct lifting position.

[0017] As a further aspect of the present invention: a clamping component is installed inside the positioning column, and a driving component for driving the clamping component to clamp the cable reel is installed on the side of the mounting frame. The clamping component includes a bent tube, a piston rod, and a clamping block. One end of the bent tube passes through the positioning column, and the other end is coaxial with the positioning column. A piston rod is movably installed in the section of the bent tube that is coaxial with the positioning column. The other end of the piston rod is provided with an end plate, and several movable plates are hinged to the end plate. The other end of the movable plate is hinged to the clamping block, which passes through the positioning column and moves radially along the positioning column to abut against the inner wall of the cable reel shaft hole.

[0018] As a further embodiment of the present invention: the driving component includes a sealing box, an extrusion plate, and an extrusion rod. The sealing box is fixed to the side of the mounting frame, the extrusion plate is movably installed inside the sealing box, the extrusion rod is fixed to the side of the extrusion plate and extends through to the outside of the sealing box, and the extrusion plate and the surface of the vertical plate are in a state of extrusion fit. An elastic element is connected between the extrusion plate and the inner wall of the sealing box. The sealing box has several air outlets, the mounting frame has several air inlets communicating with the air outlets, and the sliding plate has a connecting hole communicating with the air inlets. The size of the connecting hole is larger than the size of the air inlets, and the connecting hole is connected to one end of the bend.

[0019] The beneficial effects of this invention are:

[0020] (1) By setting a tray with a bent shovel-shaped structure, the present invention allows the cable reel to roll directly onto the tray in the initial state so that one bent surface of the tray is in contact with the ground. This eliminates the need for manual handling and lifting, significantly reducing labor intensity and eliminating safety hazards during the handling of large-sized cable reels. At the same time, both bent surfaces of the tray are in an inclined state during the lifting process, which can reliably limit the cable reel within the tray. Combined with the limiting effect formed by the positioning pin inserted into the shaft hole, the cable reel is constrained from multiple directions, greatly enhancing the stability of the cable reel during lifting and moving, and effectively preventing the cable reel from shaking or slipping.

[0021] (2) In this invention, through the cooperation of the guide roller and the reversing groove, during the process of the telescopic component driving the pallet to rise and fall, the guide roller first moves along the arc section of the reversing groove, causing the pallet to automatically flip and adjust the cable reel from a horizontal state to an inclined limit state. Then the guide roller enters the vertical section, and the pallet maintains its posture, driving the cable reel to rise vertically. The entire posture conversion process is automatically completed by the mechanical structure, without the need for manual intervention to adjust the spatial posture of the cable reel, making the operation convenient and efficient.

[0022] (3) This invention arranges multiple sets of positioning pins along the diameter of the cable reel. When the cable reel rolls into the tray, the main toothed plate is squeezed and the mounting frame is moved through gear transmission, so that the positioning pins at the corresponding shaft hole positions are automatically inserted into the shaft hole, and the misaligned positioning pins are automatically retracted, thus achieving adaptive positioning of the shaft holes of cable reels with different diameters. At the same time, through the cooperation of the positioning sensor and the positioning sensor, the stop signal is triggered only by the sensor connected to the positioning pin inserted into the shaft hole, ensuring that the cable reel shaft hole and the winding expansion shaft are accurately aligned in height at one time, without the need for repeated manual adjustments, which greatly improves the installation alignment accuracy and installation efficiency of the cable reel.

[0023] (4) By setting up clamping and driving components, during the pallet flipping and lifting process, the extrusion rod is squeezed by the vertical plate, which introduces the gas in the sealed box into the bent tube in the positioning post inserted into the shaft hole through the air passage. This pushes the piston rod to drive the clamping block to expand radially outward and press against the inner wall of the shaft hole, thereby achieving active clamping of the cable reel. This clamping action further improves the concentricity of the cable reel shaft hole and the winding expansion shaft, ensuring that the cable reel can be smoothly fitted onto the winding expansion shaft, and further enhances the stability of the cable reel during the transfer process. Since the remaining positioning posts that are not inserted into the shaft hole have retracted, their internal air passages and connecting holes are misaligned, ensuring that the gas only enters the effective positioning posts, thus guaranteeing the accuracy and reliability of the clamping action.

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

[0037] like Figures 1-7 As shown, a cable reel lifting device includes a base 1, and the device further includes:

[0038] Frame 2 includes two sets of vertical plates 21 and one set of horizontal plates 22. The two sets of vertical plates 21 are longitudinally fixed to the base 1, and the horizontal plate 22 is fixed to the top of the two sets of vertical plates 21. A reversing groove 212 is provided on the inner side of the vertical plate 21. The reversing groove 212 is composed of a lower arc section and an upper vertical section.

[0039] The lifting frame 3 includes a set of base plates 31 and two sets of guide plates 32. A telescopic component 4 is installed on the base 1, and its output end is fixedly connected to the base plate 31. The two sets of guide plates 32 are symmetrically installed on the base plate 31 and are slidably connected along the vertical plate 21. A connecting plate 33 is provided at the bottom of the guide plate 32.

[0040] The pallet 5 includes a set of curved pallet plates 51 and two sets of support plates 52. Two sets of support plates 52 are symmetrically installed on the pallet plates 51. Guide rollers 53 are installed on the support plates 52. The guide rollers 53 move along the reversing groove 212. Two sets of rotating shafts 54 are symmetrically provided on the pallet plates 51. The rotating shafts 54 are rotatably installed on the connecting plate 33.

[0041] Positioning mechanism 6: A positioning mechanism 6 for positioning the cable reel is installed on the side of the tray 51.

[0042] In one embodiment, the tray 51 is bent, and when the cable reel is placed on the tray 51, both bent surfaces of the tray 51 are tangent to the outer periphery of the cable reel.

[0043] In practical application, in the initial state, one bent surface of the pallet 51 remains horizontal and in contact with the ground. Workers only need to roll the cable reel onto the pallet 51, ensuring the outer perimeter of the cable reel is tangent to the two bent surfaces of the pallet 51, thus completing the loading without manual handling. Subsequently, the telescopic component 4 is activated, extending it. The telescopic component 4 drives the base plate 31 and, through the guide plate 32, moves the entire pallet 5 upwards. At this time, the guide roller 53 first moves along the arc segment of the reversing groove 212, causing the pallet 51 to gradually rotate around the pivot 54. The bent surface that was originally in contact with the ground tilts accordingly until both bends... All the folded surfaces are in an inclined state, reliably limiting the cable reel within the support plate 51 to ensure stability during the lifting process; when the guide roller 53 enters the vertical section of the reversing groove 212, the support plate 51 stops flipping, causing the cable reel to maintain its vertical upward posture; at the same time, the positioning mechanism 6 positions the height of the cable reel's shaft hole, and when the shaft hole rises to the same height as the winding expansion shaft, the telescopic component 4 is closed; finally, the external horizontal moving component drives the base 1 to feed horizontally, causing the support plate 51 to move the cable reel toward the winding expansion shaft until the cable reel's shaft hole is fitted onto the winding expansion shaft, completing the auxiliary installation. By setting a bent shovel-shaped support plate 51, the cable reel can be rolled in directly, significantly reducing labor intensity. The positioning mechanism 6 ensures that the shaft hole and the winding expansion shaft are aligned in height at one time, without repeated adjustments, thus effectively improving installation efficiency. In addition, the support plate 51 can adapt to cable reels of different sizes. Compared with existing lifting platforms, which require adjusting the distance between two sets of support plates when lifting cable reels of different sizes, this can further reduce labor intensity and further improve installation efficiency.

[0044] Furthermore, the positioning mechanism 6 includes a slide 61, a mounting frame 62, positioning posts 64, and a mounting plate 65. The slide 61 is fixed to the side of the support plate 51. The mounting frame 62 is slidably mounted on the slide 61, and the mounting frame 62 is provided with several sets of positioning posts 64 for positioning the cable reel. The side of the support plate 51 is also provided with a mounting plate 65. The pinion 67 and the large gear 68 are coaxially mounted on the mounting plate 65. A main gear plate 66 is installed through the side of the support plate 51. The main gear plate 66 meshes with the pinion 67, and an elastic element 69 is connected between the main gear plate 66 and the side of the support plate 51 through a baffle. One end of the main gear plate 66 located inside the support plate 51 is wedge-shaped. The bottom of the mounting frame 62 is provided with a secondary gear plate 622, which passes through the slide 61 and meshes with the large gear 68.

[0045] The mounting frame 62 has several compartments 621. A slide plate 63 is slidably installed in the compartment 621. A fixing cylinder 631 is provided on one side of the slide plate 63. A positioning post 64 is slidably installed inside the slide plate 63 and the fixing cylinder 631. An elastic element 633 is connected between the end of the positioning post 64 and the end of the fixing cylinder 631.

[0046] The tray 51 is bent. When the cable reel is placed on the tray 51, a diameter on the end face of the cable reel intersects with the bending line of the tray 51, and the line connecting the centers of the end faces of several positioning posts 64 coincides with this diameter.

[0047] A positioning sensor 642 is provided at one end of the positioning column 64 via a connecting rod 641. The connecting rod 641 passes through the end of the fixed cylinder 631. A position sensor 8 is installed on the base 1 via a support rod. The positioning sensor 642 works in conjunction with the position sensor 8 to determine whether the cable reel has reached the correct lifting position.

[0048] In one embodiment, the pinion 67 and the gear 68 have a moving gear ratio, which allows the main gear plate 66 to move a small distance, while the gear plate 622 can drive the mounting frame 62 to move a large distance, thereby ensuring that the positioning pin 64 can be smoothly inserted into the shaft hole of the cable reel.

[0049] In practical application, when the cable reel rolls onto the support plate 51, the outer periphery of the cable reel presses against the wedge-shaped end of the main toothed plate 66, causing the main toothed plate 66 to move outward against the elastic element 69. The main toothed plate 66 drives the pinion 67 to rotate, and the coaxial large gear 68 rotates synchronously. This drives the mounting frame 62 to move along the slide block 61 towards the cable reel via the toothed plate 622. Since several positioning pins 64 are distributed along the diameter of the cable reel, there is always a set of positioning pins 64 aligned with the shaft hole of the cable reel. During the movement of the mounting frame 62, the positioning pins 64 that are not aligned with the shaft hole contact the end face of the cable reel, compress the elastic element 633, and retract into the fixed cylinder 631; while the positioning pins 64 aligned with the shaft hole smoothly insert into the shaft hole under the sliding cooperation of the slide plate 63, completing the positioning of the cable reel.

[0050] When the support plate 51 drives the cable reel to rise longitudinally, the positioning pin 64 inserted into the shaft hole is connected to the positioning sensor 642 through the connecting rod 641. When the positioning sensor 642 rises to the same height as the positioning sensor 8 on the base 1, the two sensors exchange signals to control the telescopic component 4 to stop, so that the cable reel shaft hole reaches the preset position at the same height as the winding expansion shaft. Since the other positioning pins 64 have been retracted, the position of their corresponding positioning sensors 642 is shifted accordingly and will not be triggered by the positioning sensor 8. This ensures that the stop is accurately controlled only by the positioning pins 64 in the shaft hole, achieving precise height alignment, so that the cable reel can move horizontally and fit around the winding expansion shaft, further improving installation efficiency.

[0051] By setting multiple sets of positioning posts 64 along the diameter direction of the cable reel, the positioning mechanism 6 can adapt to cable reels of different diameters, improving the versatility of the equipment; at the same time, the positioning posts 64 inserted into the shaft hole limit the cable reel during the lifting process, and work together with the two inclined bending surfaces of the support plate 51 to further enhance the stability of the cable reel during movement.

[0052] like Figures 4-9 As shown, a clamping component is installed inside the positioning post 64. A driving component 7 for driving the clamping component to clamp the cable reel is installed on the side of the mounting frame 62. The clamping component includes a bent tube 643, a piston rod 644, and a clamping block 647. One end of the bent tube 643 passes through the positioning post 64, and the other end is coaxial with the positioning post 64. The piston rod 644 is movably installed in the section of the bent tube 643 that is coaxial with the positioning post 64. The other end of the piston rod 644 is provided with an end plate 645. Several movable plates 646 are hinged on the end plate 645. The other end of the movable plate 646 is hinged to the clamping block 647. The clamping block 647 passes through the positioning post 64 and moves radially along the positioning post 64 to abut against the inner wall of the cable reel shaft hole.

[0053] The driving component 7 includes a sealing box 71, a pressing plate 72, and a pressing rod 73. The sealing box 71 is fixed to the side of the mounting frame 62. The pressing plate 72 is movably installed inside the sealing box 71. The pressing rod 73 is fixed to the side of the pressing plate 72 and extends through to the outside of the sealing box 71. The pressing plate 72 and the surface of the vertical plate 21 are in a pressing fit. An elastic element 74 is connected between the pressing plate 72 and the inner wall of the sealing box 71. The sealing box 71 has several air outlets 711. The mounting frame 62 has several air inlets 623 that communicate with the air outlets 711. The slide plate 63 has a connecting hole 632 that communicates with the air inlets 623. The size of the connecting hole 632 is larger than the size of the air inlets 623, and the connecting hole 632 is connected to one end of the bend 643.

[0054] In practical application, when the guide roller 53 moves along the arc section of the reversing groove 212, the support plate 51 flips accordingly, and the extrusion rod 73 gradually turns to a horizontal state and is squeezed by the surface of the vertical plate 21. When the guide roller 53 enters the vertical section of the reversing groove 212, the extrusion rod 73 remains in a squeezed state. The extrusion rod 73 pushes the extrusion plate 72 to move, and the gas in the sealing box 71 enters the bent pipe 643 through the air outlet 711, the air inlet 623 and the connecting hole 632, thereby pushing the piston rod 644 to move. The piston rod 644 drives each clamping block 647 to move radially outward along the positioning post 64 through the end plate 645 and the movable plate 646 until the clamping block 647 presses against the cable reel shaft. The clamping action of the inner wall of the hole enables the positioning post 64 to be coaxial with the shaft hole, thereby ensuring that when the positioning sensor 642 and the positioning sensor 8 are at the same height, the shaft hole is simultaneously coaxial with the winding expansion shaft. This not only further improves the positioning accuracy and ensures that the cable reel can be smoothly fitted onto the winding expansion shaft, but also reliably restricts the cable reel, further enhancing the stability during movement. At the same time, since the other positioning posts 64 that are not inserted into the shaft hole have been compressed and retracted, their internal bends 643 are misaligned with the corresponding connecting holes 632. The gas in the sealing box 71 can only enter the bends 643 in the positioning posts 64 that are inserted into the shaft hole, thereby ensuring that only the clamping block 647 in the shaft hole stably clamps the cable reel.

[0055] In addition, by using several clamping blocks 647 to press against the inner wall of the cable reel shaft hole, the cable reel is eventually coaxial with the winding expansion shaft. This effectively prevents some of the sector plates on the winding expansion shaft from being overloaded and damaged during the expansion process of the winding expansion shaft.

[0056] like Figure 2 and Figure 3 As shown, a number of sliding rollers 34 and a number of support rollers 35 are respectively installed on the guide plate 32. A longitudinal vertical groove 211 is opened on the outer side of the vertical plate 21. The sliding rollers 34 abut against the side of the vertical groove 211, and the support rollers 35 abut against the inner surface of the vertical groove 211.

[0057] In practical application, both the sliding roller 34 and the support roller 35 move along the vertical groove 211. The sliding roller 34 ensures that the cable reel rises and falls smoothly, while the support roller 35 keeps the cable reel stable during rise and fall.

[0058] Working principle: Initially, one bent surface of the pallet 51 is in contact with the ground, and the cable reel rolls into the pallet 51. The end face of the cable reel presses against the main tooth plate 66. Through the transmission of the small gear 67 and the large gear 68, the mounting frame 62 is driven to move, so that the positioning post 64 at the corresponding position automatically inserts into the shaft hole, completing the positioning. The telescopic component 4 is activated to extend, driving the guide plate 32 to move the tray 5 upward. The guide roller 53 first moves along the arc section of the reversing groove 212, causing the pallet 51 to flip, limiting the cable reel between the two inclined bent surfaces. During the flipping process, the extrusion rod 73 is squeezed by the vertical plate 21, and gas enters the bent tube 643 to push the clamping block 647 to expand and press against the inner wall of the shaft hole. After the guide roller 53 enters the vertical section, the pallet 51 stops flipping, driving the cable reel to rise vertically. When the positioning sensor 642 on the positioning post 64 inserted into the shaft hole is at the same height as the positioning sensor 8, the telescopic component 4 stops. Finally, the external horizontal moving component drives the base 1 to feed, fitting the shaft hole onto the winding expansion shaft, completing the installation.
