Embodiment Construction

[0052] The preferred embodiments of the present invention are introduced below, and this part is only an illustration of the present invention, rather than limiting the present invention and its application or use. Other implementation modes obtained according to the present invention also belong to the technical innovation scope of the present invention. The setting of relevant parameters in the scheme does not mean that only example values ​​can be used.

[0053] In order to use the method of center of gravity compensation to compensate the eccentric moment caused by the eccentric load, the present invention designs such figure 1 Self-levelling spreader system shown in polar coordinates. The main part of the whole system is a load-bearing box 10, which consists of a box load-bearing beam 11 supporting the upper surface plate 81, a box body load-bearing beam 11 supporting the lower surface plate 83, and a box body load-bearing beam connecting the upper and lower surfaces. 1...

Abstract

The invention relates to a horizontal automatic adjusting hanger in a polar coordinate mode and a method thereof. The method comprises: adopting a double-layer bearing box body, arranging a rotatable balancing beam at an upper layer of the box body, arranging a wing beam at the bottom of the box body, and hanging a loaded hanger structure by means of a hook of the wing beam; and arranging a movable balancing block in the balancing beam, arranging a servo motor and a reduction box driving the balancing block at one end of the balancing beam, and arranging the servomotor and the reduction box driving the balancing block, and an inclination angle sensor and a controller at the lower layer of the box body. The method has the characteristics of quickness, safety and high efficiency, and solves the problems of time waste and danger when load is adjusted to be horizontal; and during adjustment, data obtained by the inclination angle sensor are transmitted to the controller, the controller sends out command to drive the two servo motors, the balancing beam uses the servo motors to change angle of the balancing beam through the reduction box, and the balancing block uses the servo motors to rotate a screw rod to adjust position of the balancing block through the reduction box, so as to change balance moment generated by the balancing block and achieve horizontal adjustment of the load.

Description

technical field [0001] The invention belongs to the field of loading and unloading lifting devices, and relates to a polar coordinate mode horizontal automatic adjustment lifting device and a method of the loading and unloading lifting devices. Background technique [0002] In industrial production or national defense construction, it is often necessary to load and unload loads. Due to the expensive load and high precision, the level of loading and unloading process on site is very high, and precise positioning is required to avoid deformation and damage to the assembled products caused by point-to-point contact and collision. For example, in order to ensure airtightness and safety during satellite loading and unloading, surface-to-face contact should be ensured between the lower surface of the satellite (ie, the docking surface) and the base, while avoiding collisions; the assembly and lifting of aircraft and helicopters should also ensure the safety of the body structure ...
