[0008] As a further technical solution of the utility model, two groups of limiting rings are arranged on the supporting roller at intervals, and the two groups of limiting rings can be slidably connected to the supporting roller.

[0009] As a further technical solution of the utility model, two groups of limit assemblies are symmetrically arranged on the base, and the limit assemblies include a curved arm rotatably connected to the base and a limit roller rotatably connected to the other end of the limit assembly, the limit roller contacts the wire drum, and the limit roller is above the plane where the rotation center of the wire drum is located.

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0021] In order to solve the problem that it is rather laborious to install a wire reel in a wire-paying device in the prior art, the present application provides a wire-paying device capable of lifting a wire reel on the ground. The wire reel is lifted by bringing two spaced-apart support rollers closer to each other, thereby lifting the wire reel off the ground and releasing manpower. Furthermore, the two support rollers can rotate simultaneously with the rotation of the wire reel to allow the wire reel to be paid out.

[0022] Figure 1 It shows a schematic diagram of the structure of the power cable pay-off device in use; Figure 1 It can be seen that the cable drum is lifted off the ground rod by the power cable pay-off device and can be rotated to achieve the pay-off of the cable.

[0023] Figure 2 shows a schematic structural diagram of the base 100; Figure 2In the invention, the electric power cable unwinding device comprises a base 100, in which a bidirectional screw rod 110 is rotatably connected, and connecting members 120 are rotatably connected to both sides of the bidirectional screw rod 110, and one end of each group of connecting members 120 is rotatably connected to a supporting roller 130, and the two groups of supporting rollers 130 are both horizontally arranged and spaced apart; since the two connecting members 120 are distributed on both sides of the bidirectional screw rod 110 and are threadedly connected to the bidirectional screw rod 110, when the bidirectional screw rod 110 is driven to rotate, the two connecting members 120 can be driven to move in opposite directions, that is, to move closer to or farther away from each other, thereby adjusting the distance between the two supporting rollers 130, so when installing the wire drum, the two supporting rollers 130 are pre-opened so that the distance between the two supporting rollers 130 is greater than the diameter width of the wire drum, and then the base 100 is moved so that the wire drum is between the two supporting rollers 130, and the movement referred to here can be It can be moved by manpower, or a pulley can be installed at the bottom of the base 100, which is well known to those skilled in the art, and then the bidirectional screw rod 110 is driven to rotate, driving the two support rollers 130 to approach each other to lift the wire drum and make the wire drum off the ground, and when the wire drum is driven to rotate, since the support roller 130 is rotatably connected to the connecting member 120, the support roller 130 can cooperate with the rotation of the wire drum to allow the wire drum to rotate after being lifted; it should be noted that, in this embodiment, a wire-releasing device based on a unilateral support and lifting structure is provided, that is, the power output is unilateral, and in some other embodiments, in order to ensure the stability of the wire drum being lifted, the support and lifting components composed of the base 100, the bidirectional screw rod 110 and the connecting member 120 are provided with two groups, which are symmetrically distributed on both sides of the support roller 130 to achieve bilateral support and lifting, which should not be a limitation to the present application.

[0024] Figure 3 A schematic diagram of the exploded structure of the support roller 130 and the support block 140 is shown; Figure 3 In the figure, two groups of limiting rings 131 are arranged at intervals on the support roller 130, and the two groups of limiting rings 131 can be slidably connected to the support roller 130. The two limiting rings 131 can limit the wire drum in two directions to prevent the wire drum from deflecting after being lifted, and the limiting rings 131 can be locked by fixing methods such as bolts after sliding, which is well known to those skilled in the art. The limiting ring 131 has a ball on the end surface facing the wire drum, which is not shown in the figure, to prevent the limiting ring 131 from causing resistance to the rotation of the wire drum; a support block 140 is sleeved on the end of the support roller 130 away from the connecting member 120, and the lower edge of the support block 140 is in the same horizontal plane as the lower edge of the base 100. The support roller 130 is supported by the support block 140 in cooperation with the base 100 to prevent the support roller 130 from tilting when supporting the wire drum, and the support block 140 is detachably connected to the support roller 130, so it can be sleeved on the end of the support roller 130 after the wire drum is lifted.

[0025] Figure 4 A schematic structural diagram of the limit assembly 150 is shown; Figure 4 In the figure, two groups of limiting components 150 are symmetrically arranged on the base 100, and the limiting components 150 include a crank arm 151 rotatably connected to the base 100 and a limiting roller 152 rotatably connected to the other end of the limiting components 150, the limiting roller 152 abuts against the wire drum, and the limiting roller 152 is above the plane where the rotation center of the wire drum is located; after the wire drum is lifted, the limiting component 150 can be rotated to make the limiting roller 152 abut against the wire drum, so that the wire drum has two support points on both the upper and lower sides of the rotation center, ensuring the stability of the wire drum when unwinding; the crank arm 151 is connected to the base 100 through a damping shaft, and when the limiting component 150 is rotated by an external force, it can maintain the state of the external force after the external force disappears, thereby ensuring the support effect on the wire drum.

[0026] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
