[0033] A lifting belt type lifting device, comprising:

[0034] The hanging seat 1 is provided with a lifting ring 2 and is rotationally connected with a chain wheel 3, and the chain wheel 3 is rotationally driven by a drive motor 5.

[0035] The lifting rod 7 is provided below the lifting seat 1, and a chain belt 4 is connected between both ends of the lifting rod 7; the chain belt 4 is hung on the sprocket 3 and engaged with the sprocket 3.

[0036] A pair of lifting belts 10 are provided at both ends of the lifting rod 7.

[0037] An inclination sensor 12 is used to monitor the inclination angle of the lifting rod 7, and drive the rotation angle of the sprocket 3 in the forward and reverse directions according to the inclination angle.

[0038] In the initial state, the sprocket 3 is located at the middle position of the chain belt 4, the crane will lift through the lifting ring 2, and rise to a reasonable height, because the gravity center of the whole device coincides with the vertical line of the lifting point at this time, and the lifting rod 7 is in a horizontal state.

[0039] After moving to the designated position, the two ends of the workpiece 11 are hung through the two lifting belts 10.

[0040] During the lifting and leveling, the workpiece 11 is slowly lifted by the crane to make the workpiece 11 slowly separate from the placing rack, and during the lifting process, due to the structural characteristics of the workpiece 11, the gravity center of the lifting rod 7 and the workpiece 11 deviates, so that the inclination angle between them is generated, the inclination sensor 12 senses the change of the inclination angle, and starts to control the rotation of the driving motor 5 to drive the sprocket 3, so as to adjust the length of the chain belt 4 on the left side of the sprocket 3 and the length of the chain belt 4 on the right side of the sprocket 3, so as to overcome the change of the inclination angle caused by the deviation of the gravity center of the lifting rod 7 and the workpiece 11, and through continuous real-time adjustment, when the gravity center position of the lifting point coincides with the gravity center position of the lifting rod and the workpiece 11 hung below, the horizontal adjustment of the workpiece 11 is completed.

[0041] In some embodiments, the inclination sensor 12 is provided on the lifting rod 7 and is provided with a wireless signal module. It is directly arranged on the lifting rod 7 to facilitate real-time monitoring, and the inclination angle parameter can be transmitted to the control module through wireless signal, and the driving motor 5 is controlled through the control module.

[0042] In some embodiments, the sprocket 3 is installed inside the lifting seat 1; a detachable base 13 is provided below the lifting seat 1; side openings 15 are provided on both sides of the lifting seat 1 for the chain belt 4 to pass through; a lifting hole 14 for installing the lifting ring 2 is provided above the lifting seat 1.

[0043] The front and rear sides of the lifting seat 1 are respectively used to install the driving motor 5 and the electric control box 6.

[0044] Through the above structure, the whole device can be quickly assembled, and the gravity center can be as much as possible to be arranged in the center through the effective arrangement.

[0045] In some embodiments, the sling 10 is slidingly mounted on the boom 7. Since the length of the workpiece 11 is uncertain, the sliding structure is used to make it more applicable, and when the sling 10 and the workpiece 11 are hung, the length of the workpiece 11 can be pre-adjusted, thereby reducing the adjustment range of the equipment and improving the horizontal adjustment efficiency.

[0046] In some embodiments, further comprising:

[0047] A pair of limiting blocks 8 are located on both sides of each sling 10 and are slidingly mounted on the boom 7, and each limiting block 8 is fixed by a limiting bolt 9.

[0048] Since the sliding structure is used, the upper part of the sling 10 is fixed by the limiting block 8 to prevent displacement of the sling 10 due to swinging and to prevent dangerous accidents.

[0049] In some embodiments, the sling 10 is a length-adjustable structure.

[0050] In some embodiments, the boom 7 is provided with two in parallel.

[0051] In some embodiments, further comprising:

[0052] A remote control module is used to remotely control the drive motor 5. The remote control module can be a remote control handle, thereby increasing remote control, so as to prevent automatic adjustment when the sensor fails, and thereby quickly switch to manual control.

[0053] In some embodiments, the drive motor 5 is a brake clutch reducer motor. When the inclination sensor feedback signal is within the set range, the drive motor 5 stops moving and is locked by the brake to make the boom 7 horizontal, thereby achieving the effect of leveling the workpiece 11.

[0054] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
