[0019] In the figure: a first screw rod 101, a second screw rod 102, a connecting frame 103, a gear ring 104, a connecting frame driving device 105, a first plate 106, a second plate 107, a guide rod 108, a limiting rod 109, an annular limiting groove 110, and a suspended object 2. DETAILED DESCRIPTION

[0020] The preferred solution is Figures 1 to 6 As shown, an electric adjustment device for the length of a suspension rope includes a first screw rod 101 and a second screw rod 102, wherein the first screw rod 101 and the second screw rod 102 are threadedly connected to a connecting frame 103, a gear ring 104 is provided in the middle of the connecting frame 103, and the gear ring 104 is driven to rotate by a connecting frame driving device 105;

[0021] The axes of the first screw rod 101 and the second screw rod 102 coincide with each other, and the center of the ring gear 104 coincides with the axes of the first screw rod 101 and the second screw rod 102 .

[0022] This device is used to adjust the length of the suspension rope. In this embodiment, the first screw 101 and the second screw 102 are used to connect with the suspension rope. If the suspension rope is other connecting parts, the first screw 101 and the second screw 102 in the suspension rope length electric adjustment device 1 are used to connect with other connecting parts. The number of suspension rope length electric adjustment devices 1 is preferably 2 or 4. The suspension rope length is adjusted by the suspension rope length electric adjustment device 1, so as to achieve the purpose of adjusting the horizontality of the suspended object.

[0023] Furthermore, the specific structure of the electric adjustment device 1 for the length of the suspension rope is as follows:

[0024] The axes of the first screw rod 101 and the second screw rod 102 coincide with each other, and the center of the circle of the gear ring 104 coincides with the axes of the first screw rod 101 and the second screw rod 102. The first screw rod 101 is connected to the first plate 106, the second screw rod 102 is connected to the second plate 107, the first plate 106 is connected to the guide rod 108, and the guide rod 108 is inserted into the insertion hole on the second plate 107. A connecting frame driving device 105 is installed on the guide rod 108, and the connecting frame driving device 105 includes a stepping motor, which is used to drive the driving teeth to rotate, and the driving teeth are engaged with the gear ring 104.

[0025] In this embodiment, the connection frame 103 is rotated by electric drive, mainly because the weight of the suspended object is large, the size of the electric adjustment device 1 for the suspension rope length is large and the position is high, which is not convenient for manual adjustment.

[0026] The adjustment principle of the electric adjustment device 1 for the length of the hoisting rope is as follows: the connecting frame driving device 105 drives the driving teeth to rotate, the driving teeth drive the connecting frame 103 to rotate, and the connecting frame 103 is threadedly matched with the first screw rod 101 and the second screw rod 102 to adjust the distance between the first screw rod 101 and the second screw rod 102. Since the first screw rod 101 is connected to the hoisted object through the hoisting rope, and the second screw rod 102 is connected to the crane hook through the hoisting rope, and the hoisting rope is generally a steel wire rope, when the connecting frame 103 rotates, it will not cause the hoisting rope to twist.

[0027] Preferably, the connection frame driving device 105 is powered by batteries to avoid interference of wires on the connection frame 103. The connection frame driving device 105 is connected to the remote controller via a Bluetooth module.

[0028] Furthermore, to prevent the connection frame driving device 105 from axial movement, the following method is used for limiting:

[0029] An annular limiting groove 110 is provided inside the gear ring 104 . A limiting rod 109 is provided in the radial direction of the annular limiting groove 110 . The limiting rod 109 is connected to the base of the connecting frame driving device 105 .

[0030] The limiting rod 109 is radially inserted into the annular limiting groove 110 . When the connecting frame 103 rotates, the limiting rod 109 can ensure that the limiting rod 109 and the annular limiting groove 110 are always located in the same plane.

[0031] The operating principle of the utility model is as follows:

[0032] When adjusting the length of the lifting rope using the lifting rope electric adjustment device 1, the object to be lifted is placed back on the ground until the lifting rope is just free of stress, and then the lifting rope electric adjustment device 1 is turned on to adjust the length;

[0033] After the electric adjustment device 1 of the lifting rope length is adjusted, the object to be lifted is lifted again, and the level measuring device is reinstalled for measurement. If it is found that the object to be lifted is not in a level state, the level measuring device is removed and the object to be lifted is placed on the ground again, and the electric adjustment device of the lifting rope length is turned on again for adjustment. After repeated leveling cycles, the leveling is completed until the object to be lifted is in a horizontal position.

[0034] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
