[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] The following is for reference. Figure 1 and Figure 2 Description of a fixing device 100 for fixing a cable reel 200 according to an embodiment of the present utility model.

[0027] like Figure 1 and Figure 2As shown, the fixing device 100 for fixing the cable reel 200 according to an embodiment of the present invention includes: two bracket assemblies 10, two support assemblies 20, and a rotating shaft 30. The two bracket assemblies 10 are spaced apart; the two support assemblies 20 are respectively disposed on the two bracket assemblies 10 and are arranged facing each other. The support assembly 20 includes: a first bearing member 21, a second bearing member 22, and a braking member 23, along the height direction of the fixing device 100 (i.e., Figure 1 and Figure 2 (As shown in the Z direction), the second support member 22 is movably disposed above the first support member 21 and together with the first support member 21 defines the receiving hole 24. The rotating shaft 30 is rotatably engaged with the receiving hole 24. The rotating shaft 30 is adapted to be assembled with the cable reel 200. The braking member 23 is connected to the second support member 22 and can apply force to the second support member 22 to increase the friction of the rotating shaft 30.

[0028] In this embodiment, two support components 10 are spaced apart. As some embodiments of this application, the two support components 10 have the same structure and are symmetrically spaced apart. Two support components 20 are respectively disposed on the two support components 10 and are positioned opposite each other. As some embodiments of this application, the two support components 20 have the same structure and are symmetrically spaced apart.

[0029] The support assembly 20 includes a first bearing member 21, a second bearing member 22, and a braking member 23, along the height direction of the fixing device 100 (i.e., Figure 1 and Figure 2 (as shown in the Z direction), the second support member 22 is located above the first support member 21, and the second support member 22 can be positioned along the height direction of the fixing device 100 (i.e., along the Z direction). Figure 1 and Figure 2 The rotating shaft 30 moves relative to the first support member 21 in the Z direction shown. The first support member 21 and the second support member 22 together define the receiving hole 24. The rotating shaft 30 is fitted with the receiving hole 24 and can rotate relative to the receiving hole 24. The rotating shaft 30 is suitable for fitting with the cable reel 200. As some embodiments of this application, the connection method between the rotating shaft 30 and the cable reel 200 can be, but is not limited to, welding connection, snap connection, bolt connection, etc., so that the cable reel 200 can rotate relative to the fixing device 100, which facilitates the cable reel 200 to lay out the cable.

[0030] This configuration allows for changing the interval between the second support member 22 and the first support member 21, enabling flexible adjustment of the size of the receiving hole 24 according to the diameter of the rotating shaft 30 to accommodate rotating shafts 30 of different diameters. Consequently, it can accommodate cable reels 200 of different specifications, which is beneficial for improving the versatility and practicality of the fixing device 100.

[0031] The brake element 23 can be connected to the second support element 22. As some embodiments of this application, the brake element 23 can be connected to the end of the second support element 22 away from the first support element 21 (i.e., above). By manipulating the brake element 23 (e.g., rotating or flicking the brake element 23), pressure can be applied to the second support element 22 to increase the friction between the rotating shaft 30 and the first support element 21 and the second support element 22, thereby increasing the friction when the rotating shaft 30 rotates and realizing the braking of the rotating shaft 30.

[0032] As some embodiments of this application, the first support member 21 and the second support member 22 may have the same structure, which can reduce the manufacturing difficulty of the fixing device 100.

[0033] This design allows for precise control of the rotation speed of the cable reel 200 during cable release, reducing the risk of excessive cable release, cable entanglement, and collapse of the fixing device 100 caused by rapid rotation of the cable reel 200.

[0034] Therefore, the size of the receiving hole 24 can be flexibly adjusted according to the diameter of the rotating shaft 30 to accommodate cable reels 200 of different specifications, improving the versatility of the fixing device 100. Furthermore, by providing the braking element 23, force can be applied to the second bearing member 22 to increase the frictional force of the rotating shaft 30, thereby controlling the cable unloading speed of the cable reel 200, reducing the risk of excessive cable unloading, cable tangling, and collapse of the fixing device 100, and improving the safety and reliability of cable laying operations.

[0035] In some embodiments of this utility model, such as Figure 2 As shown, the support assembly 20 also includes: a plurality of rollers 25, a first support member 21 having a first groove 211, a second support member 22 having a second groove 221, the first groove 211 and the second groove 221 being constructed as part of the receiving hole 24, at least one roller 25 being rotatably disposed on the first support member 21 with a portion of its structure located in the first groove 211, at least one roller 25 being rotatably disposed on the second support member 22 with a portion of its structure located in the second groove 221, and the rollers 25 rollingly engaging with the rotating shaft 30.

[0036] The support component 20 may further include multiple rollers 25. In some embodiments of this application, the rollers 25 may be spherical or cylindrical. The first bearing member 21 may have a first groove 211, which may be a portion of the receiving hole 24. In some embodiments of this application, the first groove 211 may be a semi-circular groove. The connection between the rollers 25 and the first groove 211 may be, but is not limited to, shaft-hole connection. In some embodiments of this application, one roller 25 is disposed on the first bearing member 21; in some embodiments of this application, multiple rollers 25 are disposed on the first bearing member 21.

[0037] The second support member 22 may have a second groove 221, which may be configured as part of the receiving hole 24. As some embodiments of this application, the second groove 221 may be configured as a semi-circular groove. The connection between the roller 25 and the first groove 211 may be, but is not limited to, shaft hole connection. As some embodiments of this application, one roller 25 is provided on the second support member 22. As some embodiments of this application, multiple rollers 25 are provided on the second support member 22.

[0038] The roller 25 and the rotating shaft 30 can roll together. When the rotating shaft 30 rotates, the roller 25 also rotates. The friction between the rotating shaft 30 and the roller 25 is rolling friction. Rolling friction can reduce the frictional force between the roller 25 and the rotating shaft 30, reduce energy loss, and thus reduce the labor intensity of the workers. In addition, it can also reduce the wear of the rotating shaft 30 and the support component 20, and increase the service life of the rotating shaft 30 and the support component 20. This is beneficial to reducing the maintenance cost of the fixing device 100 and improving cost-effectiveness.

[0039] In some embodiments of this utility model, such as Figure 2 As shown, both the first support member 21 and the second support member 22 are provided with multiple rollers 25, and the multiple rollers 25 of the support assembly 20 are arranged around it.

[0040] The first support member 21 has multiple rollers 25, and the second support member 22 has multiple rollers 25. The multiple rollers 25 are arranged around the outside of the rotating shaft 30, and the multiple rollers 25 are in rolling contact with the rotating shaft 30.

[0041] This design can further reduce the friction when the shaft 30 rotates, reduce energy loss, and thus reduce the labor intensity of the workers. In addition, it can further reduce the wear of the shaft 30 and the support assembly 20, and improve the service life of the shaft 30 and the support assembly 20.

[0042] In some embodiments of this utility model, such as Figure 2 As shown, the brake element 23 is configured as a manual brake element 23 or an electric brake element 23.

[0043] In some embodiments of this application, the brake element 23 can be configured as a manual brake element 23. For example, the manual brake element 23 can be configured as a rocker arm, which can be manually operated to apply pressure to the second support element 22. In some embodiments of this application, the brake element 23 can be configured as an electric brake element 23. For example, the electric brake element 23 can be configured as a hydraulic press, which can be controlled to apply pressure to the second support element 22.

[0044] This configuration allows the fixing device 100 to have multiple braking methods, which can be selected according to actual needs, providing better selectivity.

[0045] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the support assembly 20 also includes a support member 26 and a drive member 27, along the height direction of the fixing device 100 (i.e., Figure 1 and Figure 2 (as shown in the Z direction), the support member 26 is located below the first bearing member 21, and the driving member 27 is located on the support member 26 and is used to drive the first bearing member 21 along the height direction of the fixing device 100 (i.e., the Z direction). Figure 1 and Figure 2 Move in the Z direction (as shown).

[0046] Among them, along the height direction of the fixing device 100 (i.e. Figure 1 and Figure 2 (As shown in the Z direction), the support member 26 is located below the first bearing member 21, and the drive member 27 is disposed on the support member 26. As some embodiments of this application, the drive member 27 and the support member 26 can be fixedly connected, for example, the drive member 27 and the support member 26 can be bolted, welded, snap-fitted, etc.

[0047] The driving component 27 can drive the first bearing component 21 along the height direction of the fixing device 100 (i.e., Figure 1 and Figure 2 (Z direction shown) movement. The drive member 27 can be constructed as a jack or a hydraulic cylinder. As some embodiments of this application, the drive member 27 is constructed as a jack, which is supported between the first carrier member 21 and the support member 26. The first carrier member 21 is raised or lowered by the extension and retraction of the jack, thereby realizing the adjustment of the height of the cable reel 200.

[0048] This configuration allows the first carrier member 21 to be supported by the support member 26 and the drive member 27, thereby increasing the load-bearing capacity of the fixing device 100 for the cable reel 200. Furthermore, the drive member 27 can drive the first carrier member 21 along the height direction of the fixing device 100 (i.e.,...). Figure 1 and Figure 2 The rotating shaft 30 can be moved in the Z direction as shown to adjust the height of the rotating shaft 30 according to the size parameters of the cable reel 200 and actual needs, thereby adapting to different specifications of cable reels 200 and improving the versatility and practicality of the fixing device 100.

[0049] In some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the support assembly 10 includes two columns 11. The first support member 21 includes a first support body 212 and two first connecting sleeves 213. The first support body 212 is connected between the two first connecting sleeves 213. The two first connecting sleeves 213 are slidably sleeved on the two columns 11 respectively. The second support member 22 includes a second support body 222 and two second connecting sleeves 223. The second support body 222 is connected between the two second connecting sleeves 223. The two second connecting sleeves 223 are slidably sleeved on the two columns 11 respectively.

[0050] The first bearing body 212 is located between the two first connecting sleeves 213. Both ends of the first bearing body 212 are fixedly connected to the two first connecting sleeves 213. For example, the connection method between the first bearing body 212 and the two first connecting sleeves 213 can be, but is not limited to, welding or snap-fit ​​connection. Alternatively, the first bearing body 212 and the two first connecting sleeves 213 can be integrally formed. As some embodiments of this application, the first bearing body 212 and the two first connecting sleeves 213 are integrally formed, meaning that the first bearing body 212 and the two first connecting sleeves 213 are constructed as an integrally formed part. An integrally formed part has good structural strength. By making the first bearing body 212 and the two first connecting sleeves 213 integrally formed, the connection reliability between the first bearing body 212 and the two first connecting sleeves 213 can be improved, the risk of breakage at the connection point between the first bearing body 212 and the two first connecting sleeves 213 can be reduced, and the structural strength of the first bearing member 21 can be improved.

[0051] Two first connecting sleeves 213 are respectively fitted onto two columns 11, and the first connecting sleeves 213 can slide relative to the columns 11.

[0052] The second bearing body 222 is located between the two second connecting sleeves 223. The two ends of the second bearing body 222 are fixedly connected to the two second connecting sleeves 223 respectively. For example, the connection method between the second bearing body 222 and the two second connecting sleeves 223 can be, but is not limited to, welding connection, snap connection, etc., or the second bearing body 222 and the two second connecting sleeves 223 can be integrally formed.

[0053] Two second connecting sleeves 223 are respectively fitted onto two columns 11, and the second connecting sleeves 223 can slide relative to the columns 11.

[0054] As some embodiments of this application, the column 11 can be constructed as a hollow cylindrical steel or a hollow cuboid steel. Similarly, the first connecting sleeve 213 and the second connecting sleeve 223 can be constructed as corresponding cylindrical sleeves or cuboid sleeves.

[0055] This arrangement makes the structure of the fixing device 100 reasonable, allows the first bearing member 21 and the second bearing member 22 to be movably mounted on the two columns 11, and makes the movement of the first bearing member 21 and the second bearing member 22 smooth, which helps to improve the reliability of the fixing device 100.

[0056] As some embodiments of this application, the first support body 212 has a first groove 211, and at least one roller 25 is rotatably disposed on the first support body 212 with a portion of its structure located in the first groove 211. As some embodiments of this application, the second support body 222 has a second groove 221, and at least one roller 25 is rotatably disposed on the second support body 222 with a portion of its structure located in the second groove 221.

[0057] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the bracket assembly 10 further includes: at least one limiting pin 12, and the column 11 has a plurality of mating holes 111, the plurality of mating holes 111 being along the height direction of the fixing device 100 (i.e., Figure 1 and Figure 2 Arranged in the Z direction as shown, the limiting pin 12 can be inserted into any mating hole 111 and limited to the first bearing member 21 or the second bearing member 22.

[0058] The bracket assembly 10 may further include one or more limiting pins 12, and the column 11 may have multiple mating holes 111 along the height direction of the fixing device 100 (i.e., Figure 1 and Figure 2 (As shown in the Z direction), multiple mating holes 111 are arranged at intervals. The limiting pin 12 can be inserted into any one of the mating holes 111. As some embodiments of this application, the limiting pin 12 can be located below the first connecting sleeve 213 and abut against the first connecting sleeve 213. Alternatively, the first connecting sleeve 213 can have mating holes 111, and the limiting pin 12 can be inserted into the mating holes 111. That is, the limiting pin 12 is inserted into both the first connecting sleeve 213 and the column 11. This allows the limiting pin 12 to engage with the first bearing member 21 to limit the first bearing member 21, thereby reducing the risk of the first bearing member 21 sliding downward under the pressure of the rotating shaft 30. It also reduces the risk of the engagement between the driving member 27 and the first bearing member 21 shifting due to the downward sliding of the first bearing member 21, which is beneficial to improving the reliability of the fixing device 100.

[0059] As some embodiments of this application, the limiting pin 12 can be located below the second connecting sleeve 223 and abut against the second connecting sleeve 223; alternatively, the second connecting sleeve 223 can have a mating hole 111, and the limiting pin 12 can pass through the mating hole 111. That is, the limiting pin 12 passes through both the second connecting sleeve 223 and the column 11. This allows the limiting pin 12 to engage with the second bearing member 22 to limit the position of the second bearing member 22, thereby stabilizing the position of the second bearing member 22 and improving the reliability of the fixing device 100.

[0060] In some embodiments of this utility model, the fixing device 100 further includes a pressure sensor and a controller, and the bracket assembly 10 further includes a base plate 13, the pressure sensor is disposed on the base plate 13, the column 11 is disposed on the pressure sensor, the controller is communicatively connected to the pressure sensor, and the controller is configured to trigger an alarm when the pressure detected by the pressure sensor reaches a preset pressure value.

[0061] The pressure sensor is installed between the base plate 13 and the column 11. As some embodiments of this application, the pressure sensor is installed at the connection between the base plate 13 and the column 11. The pressure sensor can monitor the pressure borne by the support assembly 10 in real time, convert the detected pressure into an electrical signal, and transmit the electrical signal to the controller.

[0062] The controller is communicatively connected to the pressure sensor. As some embodiments of this application, the controller can be configured as a PCL (Programmable Logic Controller). As some embodiments of this application, the controller and the pressure sensor can be connected via wired or wireless communication. The pressure sensor transmits electrical signals to the controller, and the controller is configured to trigger an alarm when the pressure detected by the pressure sensor reaches a preset pressure value.

[0063] By setting pressure sensors and controllers, the pressure borne by the support assembly 10 can be monitored in real time, and an alarm can be triggered when the pressure reaches the preset pressure value. This reduces the risk of overload damage to the fixing device 100 due to excessive pressure and improves the reliability of the fixing device 100.

[0064] In some embodiments of this utility model, the fixing device 100 further includes: a warning light, which is disposed on the support component 20 and is communicatively connected to the controller. The controller is configured to control the warning light to illuminate when the pressure detected by the pressure sensor reaches a preset pressure value.

[0065] The warning light and the controller can be connected via wired or wireless communication. The controller can receive the electrical signal transmitted by the pressure sensor. When the detected pressure reaches the preset pressure value, the controller can control the warning light to light up to remind the staff to perform emergency braking and to remind the surrounding personnel to pay attention to safety. This setting can improve the safety of the fixed device 100.

[0066] In some embodiments of this utility model, such as Figure 1 As shown, the base plate 13 is perpendicular to the height of the fixing device 100 (i.e., Figure 1 and Figure 2 The cross-sectional structure of the plane in the Z direction shown is an isosceles trapezoid, with the lower base of the isosceles trapezoid being closer to the other base plate 13 than the upper base.

[0067] And / or, the support assembly 10 further includes: a walking wheel and a wheel frame, the wheel frame being rotatably mounted on the base plate 13, and the walking wheel being rotatably mounted on the wheel frame.

[0068] Among them, the base plate 13 is perpendicular to the height direction of the fixing device 100 (i.e. Figure 1 and Figure 2 The cross-sectional structure of the plane in the Z direction (as shown) is an isosceles trapezoid, with the lower base of the isosceles trapezoid being closer to the other base plate 13 than the upper base. Alternatively, the support assembly 10 may also include: a traveling wheel and a wheel frame, with the wheel frame rotatably mounted on the base plate 13 and the traveling wheel rotatably mounted on the wheel frame. Alternatively, the base plate 13 is arranged along the direction perpendicular to the height of the fixing device 100 (i.e., Figure 1 and Figure 2 The cross-sectional structure of the plane (in the Z direction shown) is an isosceles trapezoid. The lower base of the isosceles trapezoid is arranged closer to the other base plate 13 than the upper base. Furthermore, the support assembly 10 also includes: a walking wheel and a wheel frame. The wheel frame is rotatably mounted on the base plate 13, and the walking wheel is rotatably mounted on the wheel frame.

[0069] The base plate 13 adopts an isosceles trapezoidal structure. The isosceles trapezoidal structure occupies a large area, which can significantly improve the stability of the base plate 13, thereby improving the overall stability of the fixing device 100. Furthermore, by arranging the lower base of the isosceles trapezoid closer to the other base plate 13 than the upper base, the fixing device 100 can remain stable during the cable reel 200 cable laying process, reducing the risk of the fixing device 100 tipping outwards and causing personal injury during the cable reel 200 cable laying process.

[0070] The wheel frame is rotatably connected to the base plate 13. For example, the connection between the wheel frame and the base plate 13 can be, but is not limited to, a hinge connection, axle hole connection, etc. The traveling wheel is rotatably connected to the wheel frame. For example, the connection between the traveling wheel and the wheel frame can be, but is not limited to, axle hole connection or snap-fit ​​connection, etc. As some embodiments of this application, the wheel frame and the base plate 13 are connected by a hinge. When the fixing device 100 is idle, the wheel frame rotates to the underside of the base plate 13 via the hinge, so that the traveling wheel contacts the ground, which allows the fixing device 100 to move. This allows the fixing device 100 to be changed according to actual needs, improving the flexibility of the fixing device 100. When the fixing device 100 is working, the wheel frame rotates to the top of the base plate 13 via the hinge, so that the traveling wheel leaves the ground and the base plate 13 contacts the ground, which allows the fixing device 100 to be positioned, providing stable support for cable laying work.

[0071] As some embodiments of this application, the bottom of the base plate 13 may be provided with a material with anti-slip properties, such as silicone or rubber, which can increase the friction between the base plate 13 and the ground, reduce the risk of the fixing device 100 moving during operation, and improve the safety of the fixing device 100.
