Automatic leveling and adjusting lifting appliance and control method thereof

Abstract

The invention provides an automatic leveling and adjusting lifting appliance and a control method thereof. The lifting appliance comprises the main technical characteristics that: a y-axis guide rail arranged on the upper part of a frame is provided with a sliding device which moves a lifting device in an x axis, and a y-axis driving mechanism of the sliding device; a lifting device is arranged on the upper part of the sliding device; the frame is also provided with an inclination sensor, a system controller and a drive motor circuit device; and the system controller reads inclination data sent by the inclination sensor, carries out calculation according to the read inclination data, and outputs a control signal required by leveling and adjusting the lifting appliance to the drive motor circuit device so as to drive an X-axis motor and a Y-axis motor to do cyclic action until the inclination data read by the system controller meets the requirements of leveling and adjusting. The lifting appliance and the control method thereof have the advantages of high automation degree, accurate leveling and adjusting, convenient operation and flexible use.

Description

technical field [0001] The invention belongs to the technical field of hoisting and conveying spreaders, in particular to a spreader capable of automatically leveling and adjusting the attitude of suspended objects and a control method thereof. Background technique [0002] In important fields such as logistics, machinery, chemical industry, metallurgy, weapons, aerospace and aviation, spreaders are necessary tools or equipment commonly used in lifting, handling and hoisting operations. In some special fields, the hoisting and hoisting operation of the hoisted objects needs to maintain a high level of precision or maintain a predetermined inclination angle during the hoisting and hoisting process. Since the traditional spreader does not have the function of automatic leveling, in order to maintain the balance of the hoisted item during the hoisting process, it is often necessary to calculate the position of the center of mass of the hoisted item in advance, determine the pos...

Problems solved by technology

Since the traditional spreader does not have the function of automatic leveling, in order to maintain the balance of the hoisted item during the hoisting process, it is often necessary to calculate the position of the center of mass of the hoisted item in advance, determine the position of the lifting point according to the position of the center of mass, and then select the position according to the position of the hoisting point. or adjust the position of the hook on the sling and the length of the sling to achieve the level of the hoisted item or maintain a predetermined inclination angle, which takes a lot of time, and in the actual lifting process, On the basis of the above calculation and adjustment, it is often necessary to carry out several trial lifting adjustments to ensure safety.

Therefore, the entire hoisting process is not only time-consuming and laborious, but also a slight deviation may cause an overturning accident, resulting in loss of personnel and equipment. At the same time, this method also has the following disadvantages:

[0005] (3) Due to the aforementioned deviation, the lifting point and the length of the sling often need to be adjusted repeatedly, which is labor-intensive and time-consuming, and the work efficiency is low;

[0006] (4) Due to the aforementioned deviation, it may even cause damage to the suspended objects
