[0017] See also Figure 1 A power cable manhole cover handling tool includes a crossbeam 2, a mounting plate 21 is symmetrically welded on the upper surface of the crossbeam 2, a motor 3 is mounted on the surface of the mounting plate 21, a winding roller 31 is mounted on the rotating shaft of the motor 3 through the mounting plate 21, a lifting rope 32 is fixedly connected to the surface of the winding roller 31, and the motor 3 rotates to drive the winding roller 31 to reel in the lifting rope 32 to lift the manhole cover.
[0018] See also Figure 1 and Figure 3A balance bar 1 is welded at the lower end of the beam 2. The balance bar 1 is symmetrically welded at both ends of the beam 2. The balance bar 1 increases the stability of the beam 2 during lifting. A universal wheel 11 is installed on the lower surface of the balance bar 1 to facilitate the movement of the handling device.
[0019] See also Figure 1 and Figure 2 Positioning blocks 22 are symmetrically welded on the lower surface of the crossbeam 2, and guide rollers 23 are installed on the rotating shaft between the positioning blocks 22. The surface of the guide rollers 23 is connected with a lifting rope 32. The guide rollers 23 guide the lifting rope 32. When lifting, the guide rollers 23 are located at the upper end of the manhole cover.
[0020] See also Figure 2 A reserved opening 24 is provided on the surface of the cross beam 2, and the reserved opening 24 is used for inserting the lifting rope 32. The lifting rope 32 is inserted into the inner side of the reserved opening 24. The lifting rope 32 adopts a 5.2 cm steel wire rope, and the maximum lifting weight of the lifting rope 32 is 1.5 tons.
[0021] See also Figure 1 and Figure 2 The lower end of the lifting rope 32 is fixedly connected to a limiting shaft 33. The limiting shaft 33 is composed of a large cylinder and a small cylinder. A bearing 34 is installed on the surface of the small cylinder and a connecting port is provided at the top thereof for connecting the lifting rope 32. The large cylinder is used to limit the bearing 34. A bearing 34 is installed on the surface of the limiting shaft 33. The setting of the bearing 34 facilitates the rotation of the manhole cover lifted from the bottom.
[0022] See also Figure 1 The surface of the bearing 34 is connected with a hook 35 through a composite lifting rope, and a connecting ear is welded on the surface of the bearing 34. The composite lifting rope is connected to the bearing 34 through the connecting ear. The hook 35 is T-shaped. The hook 35 is inserted into the plug hole of the manhole cover, and then the hook 35 is rotated so that its horizontal surface overlaps with the inner wall of the manhole cover, which is convenient to use.
[0023] See also Figure 1 A switch 25 is installed on the surface of the beam 2, and the switch 25 controls the forward rotation, stop and reverse rotation of the motor 3.
[0024] The working principle of this scheme is: when the power cable manhole cover handling tool is used, the device is first moved to the manhole cover position so that the guide roller 23 is located at the center position above the manhole cover, and then the hook 35 is inserted into the inner side of the manhole cover plug hole to complete the connection between the handling tool and the manhole cover, and then the switch 25 is used to control the motor 3 to rotate forward, driving the winding roller 31 to rotate. Because one end of the lifting rope 32 is connected to the surface of the winding roller 31, the manhole cover will be lifted when the winding roller 31 reels the lifting rope 32, thereby reducing the difficulty of handling the power cable manhole cover and reducing the number of people required to complete the work; because the hook 35 is connected to the surface of the bearing 34 through the composite lifting rope, the bearing 34 can rotate along the limit shaft 33, and therefore, the manhole cover can be easily rotated and lifted through the setting of the bearing 34, which can reduce the torque generated when the lifting rope 32 is rotated; because the universal wheel 11 is installed under the balance bar 1, the movement of the handling device can be facilitated through the setting of the universal wheel 11.
