Description

Technical Field

[0001] This invention relates to the field of cable reel equipment technology, and in particular to an adjustable power cable reel storage and transfer device. Background Technology

[0002] In power engineering construction and equipment maintenance, the storage and transfer of cable reels are common and demanding tasks. Currently, cable reels are often stored using simple fixed supports, pallets, or placed directly on the ground. For transfer, common handling equipment such as hydraulic pallet trucks, forklifts, or flatbed trolleys are typically used. Existing technologies include some cable reel racks that combine storage and easy movement functions. Their basic structure includes a support shaft or two support arms for inserting into the center hole of the cable reel and lifting it off the ground, with casters installed on one side of the bottom for easy movement.

[0003] However, in practical applications, the length and angle of the support arm or support shaft of most existing cable reel storage and transfer devices are usually fixed, or have only very limited adjustment capabilities. This makes the operation extremely inconvenient when switching the cable reel from a static storage state to a transfer state (or vice versa). Specifically, during storage, the support arm needs to be fully inserted into the center hole of the cable reel to maintain stability. However, before transfer, the entire device needs to be tilted so that the casters at the bottom touch the ground, and then the tilted device is pushed for transfer. During the transfer process, because the device remains tilted, the excessively long support arm is very likely to collide or interfere with the inner wall or flange of the cable reel. It often requires multiple people to work together or repeatedly adjust the position of the cable reel to complete the mode switch, which is inefficient and poses a safety risk. Summary of the Invention

[0014] In one embodiment, a first slot is provided on the wheel seat, the first slot being located on the side of the wheel seat opposite to the roller;

[0015] The roller mechanism further includes an insert plate assembly; the insert plate assembly includes a first insert plate and a positioning plate, the first insert plate is connected and fixed to the positioning plate, the first insert plate is detachably inserted into the first slot, and when the first insert plate is inserted into the first slot, the positioning plate abuts against and fits against the outer surface of the base.

[0016] In one embodiment, the number of the receiving slot, the roller and the first insert plate are multiple in a one-to-one correspondence;

[0017] The number of positioning plates and the number of rotating shafts are one-to-one, and the length direction of each positioning plate is arranged parallel to the axial direction of the rotating shaft.

[0018] In one embodiment, the bearing mechanism includes a bearing shaft and two bearing seats;

[0019] Both ends of the bearing shaft are provided with limiting components. The limiting components include two limiting rings. Both limiting rings are connected and fixed to the bearing shaft. The two limiting rings are arranged at intervals to form an annular groove.

[0020] The two support seats are respectively installed on one end of the two lifting and telescopic mechanisms. Each support seat includes a support body, a movable buckle, and a locking member. The support body is located in the annular groove. The movable buckle is flip-covered on the support body and fastens the support shaft to the support body. The locking member is used to lock and fix the support body to the movable buckle so that the support shaft can be rotatably installed in the support seat.

[0021] In one embodiment, the bearing shaft includes a first shaft body and a second shaft body;

[0022] The first shaft and the second shaft are arranged coaxially and are screwed together.

Then, the lifting and telescopic mechanism is controlled to extend, and the entire cable reel is lifted off the ground again, and the base is placed stably on the ground. During the transfer process, the lifting and telescopic mechanism is retracted to ground the cable reel and lift the roller mechanism off the ground. Then, the roller is flipped to the bottom of the base, and the lifting and telescopic mechanism is controlled to extend again, lifting the cable reel off the ground. This allows for transfer. It can be seen that the storage and transfer of this application can achieve rapid and smooth switching between modes without the need for an overall tilting device or repeated adjustments by multiple people. This avoids the complex operation caused by tilting devices, improves operational efficiency, and effectively reduces interference between support components and cable reels, thereby improving operational safety and work efficiency.

[0042] 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 embodiments described below 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.

[0043] In power engineering construction and equipment maintenance, the storage and transfer of cable reels are common and demanding tasks. Currently, cable reels are often stored using simple fixed supports, pallets, or placed directly on the ground. For transfer, common handling equipment such as hydraulic pallet trucks, forklifts, or flatbed trolleys are typically used. Existing technologies include some cable reel racks that combine storage and easy movement functions. Their basic structure includes a support shaft or two support arms for inserting into the center hole of the cable reel and lifting it off the ground, with casters installed on one side of the bottom for easy movement.

[0044] However, in practical applications, the length and angle of the support arm or support shaft of most existing cable reel storage and transfer devices are usually fixed, or have only very limited adjustment capabilities. This makes the operation extremely inconvenient when switching the cable reel from a static storage state to a transfer state (or vice versa). Specifically, during storage, the support arm needs to be fully inserted into the center hole of the cable reel to maintain stability. However, before transfer, the entire device needs to be tilted so that the casters at the bottom touch the ground, and then the tilted device is pushed for transfer. During the transfer process, because the device remains tilted, the excessively long support arm is very likely to collide or interfere with the inner wall or flange of the cable reel. It often requires multiple people to work together or repeatedly adjust the position of the cable reel to complete the mode switch, which is inefficient and poses a safety risk.

[0045] To address this issue, this invention provides an adjustable power cable reel storage and transfer device to solve the problems of inconvenient operation and low efficiency in the storage and transfer switching process in the prior art, thereby reducing interference between the support components and the cable reel and improving operational efficiency and safety.

[0046] The following is for reference. Figures 1 to 6 This invention describes an adjustable power cable reel storage and transfer device provided in an embodiment of the present invention.

[0047] Please see Figures 1 to 4 The present invention provides an adjustable power cable reel 4 storage and transfer device, comprising:

[0048] Supporting mechanism 1 is used to support cable reel 4;

[0049] At least two roller mechanisms 2, including a base 20, a rotating member 21 and a roller member 22, wherein the roller member 22 is rotatably mounted on the base 20 via the rotating member 21, and the rotating member 21 is configured to be drivably rotated to cause the roller member 22 to flip to the bottom of the base 20 or to flip to the top of the base 20;

[0050] At least two lifting and telescopic mechanisms 3, one end of each lifting and telescopic mechanism 3 is connected and fixed to the base 20 of each roller mechanism 2, and the other end of each lifting and telescopic mechanism 3 is connected and fixed to the bearing mechanism 1.

[0051] The operation of this embodiment includes a transfer state and a storage state of the power cable reel 4. The following describes an operation process from the transfer state to the storage state, and an operation process from the storage state to the transfer state:

[0052] During the transfer and storage process, the lifting and telescopic mechanism 3 is controlled to retract during the transfer phase. The retraction of the lifting and telescopic mechanism 3 causes the cable reel 4 on the bearing mechanism 1 to descend smoothly until the cable reel 4 contacts the ground. Then, the lifting and telescopic mechanism 3 is controlled to continue retracting, causing the roller mechanism 2 to lift off the ground. After the roller mechanism 2 lifts off the ground, the roller component 22 is flipped to the top of the base 20. Then, the lifting and telescopic mechanism 3 is controlled to extend, the base 20 is grounded again, and the entire cable reel 4 is lifted off the ground again. The base 20 is then placed stably on the ground, at which point it can be placed stably.

[0053] During the transition from storage to transport, the lifting and telescopic mechanism 3 retracts during storage, causing the cable reel 4 on the bearing mechanism 1 to descend smoothly until it contacts the ground. Then, the lifting and telescopic mechanism 3 continues to retract, lifting the roller mechanism 2 off the ground. Once the roller mechanism 2 is off the ground, the roller component 22 flips to the bottom of the base 20. Then, the lifting and telescopic mechanism 3 extends, the base 20 is grounded again, and the entire cable reel 4 is lifted off the ground again, with the roller component 22 of the base 20 placed on the ground. At this point, the transport can begin.

[0054] Therefore, the advantage of this embodiment is that the storage and transfer process of this application only requires the cooperation of the lifting and telescopic mechanism 3 and the roller mechanism 2 to enable the cable reel 4 to quickly and smoothly switch between storage and transfer modes. It does not require the overall tilting device or repeated adjustments by multiple people as in traditional technology, thus avoiding the complicated operation caused by the tilting device, improving the operation efficiency, and effectively reducing the interference between the support components and the cable reel 4 to improve the operation safety and work efficiency.

[0055] In one specific embodiment, such as Figure 3 and Figure 4 As shown, a feasible mating structure for the base 20, the rotating member 21, and the roller member 22 is further provided. The side wall of the base 20 is provided with a receiving groove 200 for accommodating the roller member 22. The receiving groove 200 extends along the height direction of the base 20 and passes through the top and bottom of the base 20. The rotating member 21 includes a rotating shaft 210 and a driving part 211. The rotating shaft 210 is rotatably inserted into the receiving groove 200 and at least partially extends out of the base 20. The rotating shaft 210 is connected to the roller member 22. The driving part 211 is connected to the rotating shaft 210. That is, one end of the rotating shaft 210 is located outside the base 20 and connected to the driving part 211. One end of the rotating shaft 210 passes into the base 20 and through the entire receiving groove 200 of the base 20. The driving part 211 is used to drive the rotating shaft 210 to rotate so that the roller member 22 flips in the receiving groove 200. For example, the driving part 211 can be a manual crank drive or an electric drive device to facilitate switching operations.

[0056] In the specific implementation of this embodiment, when it is necessary to flip the roller component 22 to the bottom of the base 20, the operator can drive the rotating shaft 210 to rotate in a preset direction by operating the drive unit 211. At this time, the roller component 22 connected to the rotating shaft 210 rotates synchronously. During the flipping process, since the side slot, top opening and bottom opening of the receiving groove 200 are ensured, the roller component 22 is flipped in the slotted space of the receiving groove 200 until the roller component 22 is flipped to the bottom of the base 20. Similarly, when the roller component 22 is to be flipped to the top of the base 20, it is only necessary to drive the rotating shaft 210 to rotate in the opposite direction by the drive unit 211, and the roller component 22 can be flipped back to the top of the base 20 along the original path.

[0057] Understandably, the structure of the receiving groove 200, which runs through the height and has slots on the side, not only provides ample space for the roller component 22 to rotate, but also avoids interference with other components of the base 20 during the rotation process, ensuring smooth operation. When the device is in storage, the roller component 22 rotates to the top of the receiving groove 200, and then to the top of the base 20. At this time, the bottom of the base 20 contacts the ground, increasing the contact area with the ground and significantly improving the static stability of the device. This effectively prevents the cable reel 4 from tipping over due to external impact or slight unevenness of the ground. When the cable reel 4 needs to be transferred, the roller component 22 is rotated to the bottom of the receiving groove 200 by the drive unit 211, and then to the bottom of the base 20. With the help of the rolling characteristics of the roller 221, the operator can easily push the device to complete the position adjustment, greatly reducing the labor intensity of manual handling.

[0058] In one specific embodiment, such as Figure 3 and Figure 4 As shown, a feasible mating structure between the roller component 22 and the base 20 is further provided. The roller component 22 includes a wheel seat 220 and a roller 221. The wheel seat 220 is connected and fixed to the rotating shaft 210, and the wheel seat 220 extends at least partially out of the receiving groove 200. The roller 221 is located outside the receiving groove 200 and is rotatably mounted on the protrusion of the wheel seat 220. For example, the roller 221 and the wheel seat 220 can be mated using a fixed wheel or a universal wheel structure. The specific mating structure is prior art and is not limited here.

[0059] In this specific implementation, when the drive unit 211 drives the rotating shaft 210 to rotate in the forward direction, the wheel seat 220, which is fixed to the rotating shaft 210, rotates synchronously with the rotating shaft 210. Since the receiving groove 200 has slots on the side and is open at the top and bottom, the wheel seat 220 drives the roller 221 on its protrusion to rotate smoothly in the slotted space of the receiving groove 200 until the roller 221 rotates to the bottom of the base 20. Since the roller 221 is located outside the base 20 and its receiving groove 200, the device is completely switched to the transfer state at this time. The operator can easily push the device to complete the position adjustment of the cable reel 4 by using the rolling characteristics of the roller 221. When it is necessary to switch the device to the storage state, the drive unit 211 drives the rotating shaft 210 to rotate in the reverse direction, and the wheel seat 220 drives the roller 221 to rotate along the original path, so that the roller 221 returns to the top of the receiving groove 200 and is located on the top of the base 20.

[0060] Understandably, the advantage of this setup is that the wheel seat 220 is directly connected and fixed to the rotating shaft 210, which ensures that the power of the rotating shaft 210 is accurately transmitted to the roller component 22, making the flipping action responsive and stable. The design that the wheel seat 220 extends at least partially out of the receiving groove 200 and the roller 221 is located outside the groove ensures that the roller 221 can smoothly contact the ground when flipped to the bottom of the base 20, achieving smooth rolling and transfer. At the same time, when flipped to the top, the roller 221 will not rub against or obstruct other components due to being too close to the inside of the base 20, further improving the smoothness of the device's operation.

[0061] In one embodiment, such as Figure 3 and Figure 4 As shown, in order to fix the roller component 22 after rotation, a first slot 2200 is provided on the wheel seat 220. The first slot 2200 is located on the side of the wheel seat 220 away from the roller 221. The roller mechanism 2 also includes a plate assembly 23. The plate assembly 23 includes a first plate 230 and a positioning plate 231. The first plate 230 is connected and fixed to the positioning plate 231. The first plate 230 can be pulled out and inserted into the first slot 2200. When the first plate 230 is inserted into the first slot 2200, the positioning plate 231 abuts against and fits against the outer surface of the base 20. That is, when the plate assembly 23 is inserted into the receiving groove 200, the first plate 230 of the plate assembly 23 is inserted into the first slot 2200, while the positioning plate 231 of the plate assembly 23 is snapped against and fits against the outer surface of the base 20.

[0062] In this specific implementation, when the roller 221 is rotated to the target position, such as the bottom or top of the base 20, the operator can insert the insert plate assembly 23 into the receiving groove 200 so that the first insert plate 230 is aligned with the first slot 2200 on the wheel seat 220 and inserted. At this time, the positioning plate 231 is tightly attached to the outer surface of the base 20. Through the mechanical cooperation between the insert plate and the slot and the abutment and limiting of the positioning plate 231 on the base 20, the rotation of the wheel seat 220 is effectively locked.

[0063] Understandably, when the insert plate assembly 23 is inserted into the receiving groove 200, the insert plate assembly 23 will abut against and fit against the wheel seat 220 and the base 20, thereby restricting the rotation of the wheel seat 220. This locking method effectively prevents the roller 221 from accidentally flipping during the transfer process, causing the device to tip over or shift its position during storage, thus ensuring the safety of the cable reel 4 during storage and transfer.

[0064] Based on the above embodiments, such as Figure 3 and Figure 4 As shown, in one embodiment, to further enhance the stability of the locking, the number of receiving slots 200, rollers 22, and first insert plates 230 are multiple in a one-to-one correspondence, and the receiving slots 200 are arranged in an array on the base 20; the number of positioning plates 231 and rotating shafts 210 are multiple in a one-to-one correspondence, and the length direction of each positioning plate 231 is arranged parallel to the axial direction of the rotating shaft 210, and the two rotating shafts 210 are arranged parallel to each other on both sides of the base 20; exemplaryly, four receiving slots 200 can be provided on a base 20, and the four receiving slots 200 are arranged in an array on both sides of the base 20. That is, there are two receiving slots 200 on the same side of the base 20, and the number of rollers 22 is also four, and the number of first inserts 230 of the insert assembly 23 is also four; there are two rotating shafts 210, each rotating shaft 210 passing through the two receiving slots 200 on the same side of the base 20, and there are two positioning plates 231 of the insert assembly 23, each positioning plate 231 is arranged on one side of the base 20, and two first inserts 230 are connected and fixed on each positioning plate 231. The first two rollers 22 can be fixed wheels, and the last two rollers 22 are omnidirectional wheels equipped with foot brakes.

[0065] In this embodiment, the same insert plate assembly 23 can be simultaneously inserted into the two receiving slots 200 of the base 20. Since the two rollers 22 on the same side of the base 20 are driven by the same rotating shaft 210, when the two first insert plates 230 on a positioning plate 231 can be inserted into the first slots 2200 of the two wheel seats 220 on the same side of the base 20, the two rollers 22 on the same side of the base 20 can be simultaneously rotated and locked.

[0066] Understandably, the simultaneous locking operation of two roller components 22 on the same side via the same insert plate assembly 23 eliminates the need for individual locking, significantly simplifying the operation and improving the device's securing efficiency before storage or transport. The cooperation of multiple first insert plates 230 with slots increases the number of locking points, resulting in more even force distribution on the roller components 22. This effectively prevents loosening of individual locking structures due to concentrated force, significantly enhancing locking stability. The array-like layout design ensures more balanced force distribution on both sides of the base 20, preventing tilting or swaying during transport and improving overall safety. Furthermore, the combination of front fixed wheels and rear omnidirectional wheels ensures both stability in straight-line movement and flexibility in turning during transport. A foot brake can lock the omnidirectional wheels when the device is parked or stored, preventing them from rolling and enhancing device stability.

[0067] In one specific embodiment, such as Figure 1 , Figure 2 and Figure 5 As shown, a feasible structure for the bearing mechanism 1 is further provided. The bearing mechanism 1 includes a bearing shaft 10 for insertion into the center hole of the cable reel 4 and two bearing seats 11. Both ends of the bearing shaft 10 are provided with limiting components 102. Each limiting ring 1020 includes two limiting rings 1020, both of which are connected and fixed to the bearing shaft 10. The two limiting rings 1020 are spaced apart to form an annular groove, which provides axial positioning for the seat body 110 or the movable buckle 111 of the bearing seat 11. The two bearing seats 11 are respectively installed on one end of the two lifting and telescopic mechanisms 3. The bearing seat 11 includes a seat body 110, a movable buckle 111, and a locking element 112. The seat body 110 has a first semi-circular groove, and the movable buckle 111 has a second semi-circular groove. When the main body 110 is engaged with the movable buckle 111, the first semi-circular groove and the second semi-circular groove form an annular placement groove for accommodating the bearing shaft 10. The carrier body 110 is located in the annular slot. The movable buckle 111 and the carrier body 110 are hinged separately. The movable buckle 111 can be flipped to cover the carrier body 110. The movable buckle 111 engages the bearing shaft 10 with the carrier body 110. The locking member 112 is used to lock and fix the seat body and the movable buckle 111 so that the bearing shaft 10 can be rotatably installed in the carrier 11. For example, the locking member 112 can be a fastening bolt or a quick lock. For example, the docking ends of the carrier body 110 and the movable buckle 111 are respectively provided with connecting ears with through holes. By passing the bolt through the through hole and fastening it with a nut, quick locking and unlocking can be achieved.

[0068] In this specific implementation, after the bearing shaft 10 passes through the center hole of the cable reel 4, the operator can first align the annular slots at both ends of the bearing shaft 10 with the carrier bodies 110 of the two bearing seats 11, so that the carrier bodies 110 are precisely embedded in the annular slots; then flip the movable buckle 111 so that it tightly covers the top of the carrier body 110, and securely fasten the bearing shaft 10 in the carrier body 110; finally, by tightening the locking member 112, the movable buckle 111 and the carrier body 110 are locked and fixed. At this time, the bearing shaft 10 can rotate smoothly in the bearing seat 11, which meets the rotation requirements of the cable reel 4 when it is being retracted and extended.

[0069] Understandably, the limiting effect of the annular groove effectively prevents the axial movement of the bearing shaft 10, ensuring the stability of the cable reel 4. Furthermore, the combination of the movable buckle 111, the carrier body 110, and the locking element 112 simplifies the installation and disassembly process of the bearing shaft 10, eliminating the need for complex tools and significantly improving ease of operation. Moreover, the two ends of the bearing shaft 10 can be detachably distributed on the two carrier seats 11, ensuring that the bearing shaft 10 is subjected to uniform force, avoiding structural deformation caused by stress concentration on one side, and further enhancing the load-bearing capacity and overall stability of the bearing mechanism 1.

[0070] In one embodiment, such as Figure 5 As shown, in order to reduce the sliding friction of the bearing shaft 10, a plurality of rolling balls 1110 are embedded on the opposing surfaces of the movable buckle 111 and the carrier body 110. The plurality of rolling balls 1110 are arranged in a ring on the annular placement groove formed by the movable buckle 111 and the carrier body 110. The rolling balls 1110 can be movably fitted with the bearing shaft 10, thereby forming a sliding bearing structure between the bearing shaft 10 and the carrier 11.

[0071] In the specific implementation of this embodiment, when the lifting and telescopic mechanism 3 is raised or lowered, the bearing seat 11 maintains contact and relative positioning with the bearing shaft 10 through the rolling ball 1110. At the same time, the rolling friction allows the bearing shaft 10 to rotate easily relative to the bearing shaft 10 when necessary (such as adjusting the cable reel 4 cable laying angle), reducing operating resistance.

[0072] In one embodiment, such as Figure 6 As shown, a feasible structure for the bearing shaft 10 is further provided. The bearing shaft 10 includes a first shaft body 100 and a second shaft body 101. The first shaft body 100 and the second shaft body 101 are arranged coaxially and are screwed together. For example, an external thread is provided on the outer side wall of one end of the first shaft body 100, and a screw hole is provided at the end of the second shaft body 101. The first shaft body 100 and the second shaft body 101 are screwed together through the external thread and the screw hole. Both the first shaft body 100 and the second shaft body 101 are steel components.

[0073] In this embodiment, the axial length of the bearing shaft 10 can be adjusted to a suitable size by rotating the first shaft 100 and the second shaft 101, and then the entire bearing shaft 10 is placed in the two bearing seats 11, thereby achieving a stable placement of the bearing shaft 10.

[0074] Understandably, the screw connection between the first shaft 100 and the second shaft 101 can adjust the axial length of the entire bearing shaft 10. This design allows the same device to adapt to various specifications of cable reels 4 with different center hole depths, without the need to replace the dedicated bearing shaft 10 for different sizes of cable reels 4. This improves the versatility of the device and significantly expands its applicability and versatility, eliminating the need to equip different cable reels 4 with specific shafts.

[0075] In one specific embodiment, such as Figure 5 and Figure 6 As shown, in order to limit the axial sliding of the cable reel 4 on the bearing shaft 10, the bearing mechanism 1 also includes two fastening components 12. Both fastening components 12 are installed on the bearing shaft 10 and are used to abut against both sides of the cable reel 4 to limit the axial sliding of the cable reel 4 on the bearing shaft 10. In specific implementation, the two fastening components 12 are respectively sleeved on the corresponding positions of the bearing shaft 10. According to the width of the cable reel 4 to be stored, the fastening components 12 are moved axially along the bearing shaft 10 to a position that matches the edge of the flange on both sides of the cable reel 4. It can be understood that the inner end faces of the two fastening components 12 are exactly in close contact with the flange on both sides of the cable reel 4, thereby effectively preventing the cable reel 4 from axially moving during transportation or storage.

[0076] In one embodiment, such as Figure 2 , Figure 5 and Figure 6 As shown, a feasible structure for the fastening assembly 12 is further provided. A plurality of second slots 103 are provided on the bearing shaft 10, and the plurality of second slots 103 are arranged along the axial direction of the bearing shaft 10. The fastening assembly 12 includes a fastening sleeve 120 and a second insert plate 121. The fastening sleeve 120 is sleeved on the bearing shaft 10 and is used to abut against the cable reel 4. The second insert plate 121 is located on the side of the fastening sleeve 120 away from the cable reel 4, and the second insert plate 121 is removably inserted into the second slot 103 to limit axial sliding of the fastener.

[0077] In this embodiment, the operator first places the two fastening sleeves 120 onto the bearing shaft 10 and slides them axially along the bearing shaft 10 to position them on opposite sides of the cable reel 4. Then, from the side of the fastening sleeve 120 away from the cable reel 4, the second insert plate 121 is inserted into the matching second slot 103 on the bearing shaft 10, ensuring that the second insert plate 121 is fully embedded in the slot without any looseness, thereby firmly locking the position of the fastening sleeve 120. At this time, one end of the fastening sleeve 120 is in close contact with the cable reel 4, and the other end of the fastening sleeve 120 is in close contact with the second insert plate 121, effectively preventing the fastening sleeve 120 from sliding axially during the transportation or storage of the cable reel 4, further ensuring the stable placement of the cable reel 4. When it is necessary to adjust the position of the fastening assembly 12 to accommodate cable reels 4 of different widths, simply pull out the second insert plate 121, slide the fastening sleeve 120 back to the target position, and then insert the second insert plate 121 again.

[0078] Understandably, the cooperation between the second insert plate 121 and the second slot 103 provides a simple mechanical locking method. When the fastener slides to the appropriate position and abuts against the inner side of the cable reel 4 flange, the insertion can prevent the fastener from retracting, thereby clamping and limiting the cable reel 4 from both sides. The operation is intuitive and quick, thus limiting the axial movement of the cable reel 4 and ensuring that the cable reel 4 remains stable during storage and transportation, reducing safety hazards caused by loosening. Furthermore, the design of the second slot 103 arranged axially along the bearing shaft 10 makes the adjustment range flexible and can adapt to cable reels 4 of different widths, improving the versatility of the device.

[0079] In this embodiment, as Figure 2 , Figure 5 and Figure 6 As shown, a feasible structure for the fastening sleeve 120 is further provided. The diameter of the fastening sleeve 120 gradually decreases along the axial direction. The narrow end of the fastening sleeve 120 is located on the side close to the cable reel 4. That is, the fastening sleeve 120 is a conical structure. The tip of the conical structure is located on the side close to the cable reel 4. The outer surface of the fastening sleeve 120 is provided with an anti-slip layer to increase friction. The anti-slip layer can further restrict the cable reel 4 from sliding on the bearing shaft 10.

[0080] In the specific implementation of this embodiment, when the operator slides the fastening sleeve 120 along the bearing shaft 10, its narrowing end will first contact the side of the cable reel 4. As the sliding operation progresses, the narrowing tapered structure can gradually fit the edge contour of the cable reel 4, effectively reducing the gap between the two.

[0081] Understandably, the narrowed conical structure of the fastening sleeve 120 facilitates the insertion into the center hole of the cable reel 4, and achieves initial alignment by fitting its inclined surface against the hole wall. After the fastening sleeve 120 is locked in position by the second insert plate 121, this gradually changing diameter design can further enhance the axial compressive force on the cable reel 4, preventing the cable reel 4 from undergoing slight displacement due to vibration during transportation.

[0082] In one specific embodiment, such as Figure 1 , Figure 2 and Figure 5 As shown, a feasible structure for the lifting and telescopic mechanism 3 is further provided. The lifting and telescopic mechanism 3 includes a pneumatic component, a reversing valve, a throttle valve, and an air source. The pneumatic component includes a piston, a piston rod, and a double-acting cylinder. The piston is slidably installed in the double-acting cylinder, and the piston rod is connected to the piston. The extended end of the piston rod is connected to the bearing seat 11 of the bearing mechanism 1. The bottom of the double-acting cylinder is connected and fixed to the base 20 of the roller mechanism 2. The reversing valve is connected to the rodless chamber and the rod chamber of the double-acting cylinder through a hose. The reversing valve has three positions: up, stop, and down. The reversing valve is connected to an external portable air compressor or a fixed air source at the construction site through an air inlet hose (not shown in the figure). The throttle valve is connected to the air line between the reversing valve and the double-acting cylinder and is used to adjust the lifting speed of the piston rod in the pneumatic component. In specific implementation, the pneumatic drive component drives the piston rod to perform linear telescopic motion, which can realize the extension and retraction of the lifting and telescopic mechanism 3, thereby completing the lifting and retraction of the bearing mechanism 1 and the roller mechanism 2.

[0083] It should be noted that the cylinder can be replaced with a hydraulic cylinder, and the air source can be replaced with a hydraulic source. The air source or hydraulic source can be connected to general equipment on the construction site, or a small air compressor or hydraulic station can be integrated on the base 20.

[0084] As described above, the basic structure and principle of this application are explained below. The entire process of rapid loading, lifting and transferring, auxiliary cable winding and unloading, and convenient unloading of the cable reel 4 is presented in the following text:

[0085] Preparation and loading stage: First, in the initial state, the base 20 of the roller mechanism 2 is in contact with the ground. The pneumatic component of the lifting and telescopic mechanism 3 is operated to raise the base 20 of the roller mechanism 2, flipping the two roller components 22 downwards to be perpendicular to the ground, and locking them through the first insert plate 230 and positioning plate 231 of the insert plate assembly 23 to put them in the transfer posture, keeping the piston rod of the pneumatic component in the retracted state. Next, the bearing shaft 10 of the bearing mechanism 1 is passed through the center hole of the cable reel 4, and the fastening sleeve 120 of the conical fastening assembly 12 is slid from both sides to the center, so that its outer conical surface is tightly attached to both ends of the center hole. The second insert plate 121 of the fastening assembly 12 is inserted to prevent the fastening sleeve 120 from retracting, thereby completing the initial fixation of the cable reel 4 on the bearing shaft 10 of the bearing mechanism 1.

[0086] Connection and Lifting Stage: Open the support seat 11 of the support mechanism 1 in the low position (i.e., separate the support body 110 and the movable buckle 111), and insert it into the support shaft 10 of the support mechanism 1 from the side, so that it is located between the two limiting rings 1020 at the same end of the support shaft 10; then, operate the pneumatic component of the lifting and telescopic mechanism 3 to raise its piston rod, adjust and close the support body 110 and the movable buckle 111, and use the locking component 112 to lock the two, so that the support seat 11 forms a complete ring support structure; then control the pneumatic component of the lifting and telescopic mechanism 3 to lift its piston rod, and the support seat 11 transmits the force to the support shaft 10 of the support mechanism 1. When the roller component 22 of the roller mechanism 2 contacts the ground, continue to extend the piston rod of the pneumatic component, thereby smoothly lifting the cable reel 4 off the ground and entering the transfer preparation state.

[0087] During the transfer and auxiliary operation phase: by releasing the caster wheel foot brake, the entire device can be pushed to transfer the cable reel 4; after being transferred to the target position, when it is necessary to reel in or unreel the cable, since the bearing shaft 10 of the bearing mechanism 1 is rotatably connected to the bearing seat 11 through the rolling ball 1110, the bearing shaft 10 of the bearing mechanism 1 and the cable reel 4 can be easily rotated manually, which facilitates the winding or laying of the cable and reduces the workload.

[0088] Unloading and Storage Stage: After the cable work is completed, push the device to the storage position, operate the pneumatic component of the lifting and telescopic mechanism 3 to lower its piston rod, and the cable reel 4 will fall to the ground; release the locking component 112, open the bearing seat 11 of the bearing mechanism 1, and then the roller mechanism 2 and the lifting and telescopic mechanism 3 can be removed. Finally, pull out the second plug plate, slide off the fastening sleeve 120, and the bearing shaft 10 of the bearing mechanism 1 can be pulled out, completing the unloading of the cable reel 4. The various components of the device can be stored separately, saving space.
