[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides, for example Figures 1-9 The cable laying device for power facility planning shown includes a base plate 1, on which a fixed frame 2 and a movable frame 4 are provided, and a chuck 3 for clamping the cable drum is rotatably installed on the side of the movable frame 4 facing the fixed frame 2.

[0031] The base plate 1 is also equipped with a lifting mechanism for lifting the cable drum. The lifting mechanism includes a cavity opened in the base plate 1 and a lifting platform 6 set on the upper surface of the base plate 1. The top of the lifting platform 6 is obliquely cut to form an inclined part, and the middle part of the inclined part is recessed downward to form an arc-shaped placement groove. The top of the cavity is provided with an opening, and a hydraulic cylinder 8 and four telescopic auxiliary support rods 9 are installed in the cavity. The four auxiliary support rods 9 are distributed in a rectangular array around the outside of the hydraulic cylinder 8, and the top of the four auxiliary support rods 9 and the top of the hydraulic cylinder 8 are connected to the bottom of the lifting platform 6.

[0032] Meanwhile, in this embodiment, regarding how the aforementioned movable frame 4 moves, as follows: Figures 1-5 As shown, a drive component 5 for moving the movable frame 4 is provided on the base plate 1. The drive component 5 includes two grooves opened on the base plate 1 and two movable seats 53 installed at the bottom of the movable frame 4. Threaded rods 52 are rotatably installed in both grooves, and one end of each threaded rod 52 extends to the outside of the base plate 1 and is equipped with a pulley. A synchronous belt meshes between the two pulleys. The two movable seats 53 are respectively located in the two grooves and connected to the threaded rods 52. A motor 51 is also fixed on one side of the base plate 1, and the main shaft of the motor 51 is connected to one end of one of the threaded rods 52.

[0033] As described above, during use, the device is first placed at the cable laying position using the base plate 1. Then, the cable drum with the cable wound around it is raised to the height corresponding to the chuck 3. Then, the motor 51 drives one of the threaded rods 52 to rotate. At the same time, the engagement of the pulley and the timing belt drives the other threaded rod 52 to rotate synchronously. This causes the threaded rod 52 to drive the moving seat 53 to move along the groove, thereby driving the movable frame 4 to move along the base plate 1 until the cable drum is clamped between the two chucks 3. This completes the installation of the cable drum. Then, the worker pulls one end of the cable out of the cable drum and uses mechanical equipment (such as a vehicle) to pull the cable. At this time, the chuck 3 rotates, thereby driving the cable drum to rotate and completing the cable laying.

[0034] During cable reel installation, the cable reel with the cable wound on it is placed in the placement slot on the lifting platform 6. The lifting platform 6 is then raised by the hydraulic cylinder 8, causing the cable reel to rise to the height corresponding to the chuck 3. At this point, the retractable auxiliary support rod 9 provides auxiliary support to the lifting platform 6, facilitating stable lifting. The motor 51 then drives the threaded rod 52 to rotate, causing the movable frame 4 to move. The two chucks 3 are used to install the cable reel. After installation, the hydraulic cylinder 8 lowers the lifting platform 6 back to its initial position, completing the reset. The cable is then pulled for laying, thus achieving automatic lifting of the cable reel without manual intervention. This significantly reduces the installation difficulty and labor intensity of the workers, enabling rapid installation and facilitating rapid cable laying, which is beneficial for power facility construction.

[0035] Furthermore, to facilitate the normal transmission of the synchronous belt, such as Figures 1-3 As shown, an L-shaped baffle is also provided on one side of the base plate 1, and the baffle is used to cover the pulley, synchronous belt and motor 51, which can protect the pulley, synchronous belt and motor 51.

[0036] Furthermore, to prevent impurities from falling into the groove and to ensure the normal transmission of the threaded rod 52, such as... Figures 1-5 As shown, a telescopic cover is also provided on the base plate 1 to cover the groove, and the movable end of the telescopic cover is fixedly connected to the side wall of the movable frame 4.

[0037] In another embodiment, such as Figures 1-9 As shown, the lifting platform 6 is also equipped with a limiting component 7 for quickly positioning the cable drum. The limiting component 7 includes two movable plates 71 that are disposed in the placement groove and can move relative to each other. Springs 73 are connected to the opposite sides of the two movable plates 71, and a limiting plate 72 is connected to the end of the spring 73 away from the movable plate 71.

[0038] Specifically, regarding how the two movable plates 71 move relative to each other, such as... Figures 6-9 As shown, the limiting component 7 also includes a movable groove 74 opened on the lifting platform 6. A bidirectional lead screw 78 is rotatably installed in the movable groove 74, and two movable plates 76 are provided on the bidirectional lead screw 78. One end of the two movable plates 76 is fixedly connected to one side of the two movable plates 71 respectively. One end of the bidirectional lead screw 78 extends to the outside of the lifting platform 6 and is equipped with a handwheel 75.

[0039] As described above, when the cable drum is placed on the placement groove for lifting, the double-acting screw 78 can be rotated via handwheel 75. This causes the double-acting screw 78 to drive the two moving plates 76 to move synchronously along the moving groove 74. At this time, the two moving plates 76 drive the two movable plates 71 to move away from each other, and drive the limiting plates 72 to move synchronously until the two limiting plates 72 abut against the inner walls of the cable drum. Then, under the action of spring 73, the limiting plates 72 maintain a tendency to press against the inner walls of the cable drum, thereby completing the positioning of the cable drum. After the cable drum is installed, the double-acting screw 78 is rotated in the opposite direction again by the handwheel 75. This causes the double-acting screw 78 to drive the two movable plates 71 to move towards each other through the two movable plates 76. Subsequently, the movable plates 71 drive the limiting plate 72 away from the inner wall of the cable drum, thereby separating the limiting plate 72 from the cable drum. This achieves stable positioning of the cable drum on the placement groove, preventing the cable drum from sliding on the placement groove. This, in turn, enables stable lifting of the cable drum, facilitates rapid installation of the cable drum, and is beneficial for the rapid laying of the cable.

[0040] Meanwhile, in this embodiment, such as Figures 7-9 As shown, the lifting platform 6 is also provided with a threaded hole 79, and a locking bolt 77 is screwed into the threaded hole 79. One end of the locking bolt 77 can be pressed against the outer wall of the double-acting screw 78.

[0041] After adjusting the two movable plates 71 by rotating the double-acting screw 78 using the handwheel 75, the locking bolt 77 can be screwed into the threaded hole 79 until one end of the locking bolt 77 abuts against the double-acting screw 78, thus locking the double-acting screw 78 in place. This prevents the double-acting screw 78 from rotating and causing the movable plates 71 to move, resulting in offset. This ensures the stable positioning of the cable drum and further facilitates the laying of the cable.

[0042] Furthermore, to ensure the stable movement of the movable plate 71 and the limiting plate 72 within the placement groove, such as... Figures 6-9 As shown, guide blocks are provided at the bottom of both the movable plate 71 and the limiting plate 72, and guide grooves are provided on the placement groove for the guide blocks to slide.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
