[0025] The adjustable fixing component includes a hand wheel 1, a transmission screw 3, a nut, a suspension fixing unit 5 and a baffle 4; the transmission screw 3 is arranged on the upper part of the oblique support unit 6;

[0026] The top of the transmission screw 3 is fixedly connected to the hand wheel 1; the nut and the transmission screw 3 are threadedly connected; the suspension fixing unit 5 is fixedly connected to the nut, and the bottom of the baffle 4 is fixedly connected to the suspension fixing unit 5;

[0027] An accommodating space is defined between the baffle plate 4 and the suspension fixing unit 5 , and the accommodating space is used to support the transverse axis of the cable drum.

[0028] In this embodiment, a connecting plate is provided at the connection between the vertical supporting unit 2 and the oblique supporting unit 6; screw holes are provided on the connecting plate.

[0029] In this embodiment, the transmission screw 3 passes through the screw hole, and the hand wheel 1 is arranged on one side above the connecting plate.

[0030] In this embodiment, the oblique support unit 6 is made of channel steel, and the transmission screw 3 is arranged in the groove of the channel steel.

[0031] In this embodiment, the vertical support unit 2 and the bottom support unit 7 are made of channel steel; in other embodiments, other steel materials may also be used.

[0032] In this embodiment, bottom support plates are provided at the bottom of the vertical support unit 2 and the oblique support unit 6. The bottom support plates are used to increase the contact area with the ground to prevent tilting and collapsing.

[0033] Specifically, one end of the bottom support unit 7 is connected to the bottom support plate at the bottom of the vertical support unit 2, and the other end is connected to the bottom support plate at the bottom of the inclined support unit 6; the bottom support unit 7, the bottom support plate at the bottom of the vertical support unit 2, and the bottom support plate at the bottom of the inclined support unit 6 specifically form an I-shape, an L-shape, a triangle, or other shapes that can stabilize the bottom of the entire tool.

[0037] The method of using the special tool for laying cables on a large cable drum provided by the utility model is as follows:

[0038] The two ends of the transverse axis of the cable drum are placed on the baffles 4 of two special tools respectively. When the hand wheel 1 is turned, the transmission screw 3 rotates relative to the nut, the distance between the hand wheel 1 and the nut changes, and the suspension fixing unit 5 moves upward or downward along the oblique support unit 6, thereby driving the baffle 4 to move, and finally realizing the upward and downward movement of the transverse axis of the cable drum on the baffle 4. This ensures the safe fixing of the cable, greatly reduces the consumption of manpower, materials and machines, greatly saves the cable laying cost, and improves the work efficiency.

[0039] Specifically, when it is necessary to quickly lay the cable, the hand wheel 1 is turned to move the suspension fixing unit 5 upward along the inclined support unit 6. When the cable reel is in a suspended state, the cable can be quickly laid. When the cable laying work is completed, the hand wheel 1 can be adjusted to lower the position of the suspension fixing unit 5 through the transmission screw 3 to replace the cable reel.

[0040] The special tool for laying cables on a large cable reel provided by the utility model is simple to manufacture, firm and durable, easy to operate, efficient and fast, safe and reliable, and reduces the use of cranes, which ensures the safe fixation of cables and greatly reduces the consumption of manpower, materials and machines, greatly saves the cost of cable laying and improves work efficiency.
