Dual-rotated counterweight type automatic horizontal regulation sling system

Abstract

The invention provides a dual helix counterweight type automatic horizontal adjustment hanger system, which comprises: a load bearing hanger for bearing the weight of a load; an automatic horizontal adjustment box which is arranged on the load-bearing hanger and is used for balancing the bottom surface of the load by adjusting a counterweight; a first platform and a second platform which have horizontal upper surfaces and are used for bearing the load; a first bottom surface angle sensor and a second bottom surface angle sensor which are positioned on the first platform and the second platform respectively; and a computer which is connected with the first bottom surface angle sensor and the second bottom surface angle sensor respectively, calculates a control signal according to the singles of the first bottom surface angle sensor and the second bottom surface angle sensor and transmits the control signal to the automatic horizontal adjustment box to control the position of the counterweight in the automatic horizontal adjustment box to compensate for the eccentric torque of the load and keep the bottom surface of the load in a horizontal state. Therefore, the system realizes the hoisting of precise vulnerable loads and has the advantages of high precision, high speed and safety and reliability.

Description

technical field [0001] The invention relates to an automatic level adjustment sling system, especially including a fully automatic level adjustment control system. Background technique [0002] In industrial production or national defense construction, frequent product hoisting is often required. Due to reasons such as design and manufacturing process, the center of gravity of these products often deviates from the geometric center. When hoisting, the product will tilt, and the bottom surface will therefore have an included angle with the target installation plane. If you install it directly in this case, it is easy to cause damage to the lower surface of the product. [0003] For many expensive, precise and fragile products, it is required to ensure surface-to-surface contact between the docking planes during the hoisting process, and to avoid point contact or line contact. Therefore, they have particularly high requirements on their own levelness, and the collision cause...

Problems solved by technology

For example, use a length-adjustable sling, and manually adjust the length of the sling to achieve the level of the bottom surface of the heavy object according to the measured included angle. This manual operation method is completely based on experience and gradually explored. The accuracy is difficult to guarantee, and it is time-consuming and laborious. It is often difficult to achieve the required accuracy after several hours or even a day; and the on-site participation of personnel is required, which poses a great safety hazard

Another example is to adjust the attitude of the weight by changing the length of the force arm by moving the lifting point of the crane hook on the spreader, so as to achieve the level of the bottom surface of the weight; this method can achieve a certain adjustment effect, but due to the overall The load is added to the lifting point, and it is quite difficult to move the lifting point, especially when the load is relatively heavy, and a slight movement of the lifting point will cause a drastic change in the included angle, which is not easy to stabilize, so this method is not suitable for heavy loads, High-precision hoisting

In the case of heavy loads, direct manipulation of slings, lifting points or beams requires a lot of power, which is very difficult to achieve in engineering practice, and the accuracy is difficult to guarantee

[0005] In summary, the level adjustment method of the traditional spreader has great limitations, and the industrial production department urgently needs a fully automatic level adjustment spreader system that can achieve precise lifting
