[0001] The invention relates to the technical field of cable construction, in particular to a cable laying auxiliary tool. Background Art

[0002] High-voltage cables are the main arteries of power transmission and are widely used in shield-bored subway and tunnel construction. Due to the relatively long length of high-voltage cables, they are generally wound on special cable reels. During construction, the cable reel rack is placed in the cable trough, and the cable is retracted and released by rotating the cable reel. Because the cable is of high value and easily damaged, if there is a non-straight area in the cable trough, the cable reel needs to be moved manually, and the cable needs to be manually pulled out and laid according to the shape of the cable trough, which greatly reduces construction efficiency, makes it impossible to proceed to the next process in time, and increases the labor intensity of the operators. Summary of the Invention

[0003] The technical problem to be solved by the present invention is the low construction efficiency of the existing cable reel retracting and releasing device.

[0004] In order to solve the above problems, the present invention provides a method for improving the construction efficiency of a cable reel retracting device, and the specific solution is: A cable laying auxiliary tool is used on a cable reel, including a support frame. Support platforms are provided on both sides of the support frame. The height of the support platforms on the support frame is adjustable. Bearings are provided on the support platforms. A rotating shaft is inserted in the two bearings. The rotating shaft is used to be inserted in the cable reel. A walking component is provided at the bottom of the support frame.

[0005] Compared with the prior art, the present invention adopting the above technical solution has the following beneficial effects: The present invention provides a rotating shaft for inserting the cable reel, and bearings are sleeved at both ends of the rotating shaft, and the bearings on both sides are arranged on a movable support frame, so that during construction, the support frame is pushed to move the position of the cable reel, and the cable reel is rotated by the rotating shaft, so that the cable reel is quickly retracted and released; the support platform carrying the cable reel is height-adjustable, and the height of the cable reel can be adjusted according to actual needs during use; laying cables with the auxiliary tool of the present invention saves time and effort, and the flexibility is significantly improved. It can be put into use frequently once, which greatly reduces the cost compared with the traditional method. At the same time, it greatly increases the safety of the operator and saves manpower.

[0006] Preferably, a further technical solution of the present invention is: The support frame comprises a rectangular frame at the bottom, four vertical rods are fixed on the rectangular frame, and two support platforms are respectively arranged on two vertical rods on the same side. The two vertical rods on the same side are used as the setting points of the support platforms, making the support platforms more stable.

[0007] A sleeve is mounted on the vertical rod, and two support platforms are fixed between the two sleeves on the same side. A lifting platform is installed between the two vertical rods below the two sleeves on the same side. The support platform on the same side is vertically aligned with the lifting platform, and a jack is installed on the lifting platform. With this structure, the height of the support platform can be adjusted by the jack during use.

[0008] Each support platform is equipped with a storage rack, each with a bearing slot equal to the height of the bearing. The outer ring of the bearing is fixedly inserted into the bearing slot, with the axes of the two bearings aligning. This structure allows the outer ring of the bearing to be fixed to the support platform, while the inner ring of the bearing rotates with the shaft, facilitating the rotation of the cable reel.

[0009] The two vertical rods on the same side are provided with lifting lug assemblies, which are symmetrical to each other. Through the lifting lug assemblies, the support frame can be driven by the cable reel to be lifted together and transported to the position where the cables are laid.

[0010] The lifting lug assembly includes a lifting lug compartment. One end of the lifting lug is pinned to the compartment, and the other end of the lifting lug is pivoted out of the compartment to connect to an external lifting device. This structure conceals the lifting lug within the compartment, allowing it to be pivoted out to connect to the lifting device during lifting, preventing damage to the lifting lug.

[0014] See attached Figure 1-5 An embodiment of the present invention discloses a cable laying auxiliary tool, which is used on a cable reel 4 and includes a support frame. Support platforms 8 are provided on both sides of the support frame. The height of the support platform 8 on the support frame is adjustable. Bearings 9 are provided on the support platform 8. A rotating shaft 5 is inserted into the two bearings 9. The rotating shaft 5 is used to be inserted into the cable reel 4. A walking component is provided at the bottom of the support frame.

[0015] The two vertical rods 3 on the same side are used as the setting points of the support platforms 8, so that the support platforms 8 are more stable.

[0016] In this embodiment, each support platform 8 is provided with a storage rack. Preferably, the storage rack is composed of two inverted V-shaped steel plates 81, which are welded to the support platform 8 at intervals. Two limiting bars 82 are welded and fixed to the inner sides of the two inverted V-shaped steel plates 81. The space between the two limiting bars 82 on the same inverted V-shaped steel plate 81 serves as a bearing 9 slot for placing the bearing 9. The width of the bearing 9 slot is set to be the same as the height of the bearing 9. The outer ring of the bearing 9 is fixedly inserted into the bearing 9 slot, and the axis centers of the two bearings 9 coincide. Preferably, the depth of the bearing 9 slot is set to be less than the ring diameter of the outer ring of the bearing 9 to prevent the inner ring of the bearing 9 from contacting the bearing 9 slot and affecting the rotation of the rotating shaft 5. Through the above structure, the outer ring of the bearing 9 is fixed to the support platform 8, and the inner ring of the bearing 9 rotates with the rotating shaft 5, facilitating the rotation of the cable reel 4.

[0017] In this embodiment, the two vertical rods 3 on the same side are provided with lifting lug assemblies 6, which are symmetrical to each other. Preferably, the lifting lug assemblies 6 include a lifting lug compartment 62, into which a lifting lug 61 is pinned.
