Embodiment Construction

[0039] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0040] In a low temperature environment, the decrease in temperature will easily cause the viscosity of the reducer, the oil in the push rod screw or the grease in the motor bearing to increase or freeze, resulting in an increase in static resistance, which adds an additional load to the push rod drive motor . If the equipment is lifted with a large load, the push rod drive motor may stall due to insufficient starting torque, and even cause the push rod drive motor to burn out. In addition, the brittleness of the material increases at low temperatures, and the output shaft of the push rod drive motor or reducer may There is a possibility of breakage.

Abstract

The invention relates to the field of engineering machinery, and discloses a method and device for load control and full-electric high-altitude operation equipment, the method for load control is applied to the full-electric high-altitude operation equipment, and the full-electric high-altitude operation equipment comprises a push rod driving motor which is used for achieving the lifting action of the full-electric high-altitude operation equipment. The method comprises the steps that the current actual load of the all-electric high-altitude operation equipment is obtained; acquiring the temperature of a push rod driving motor; the maximum allowable load of the all-electric high-altitude operation equipment is determined according to the temperature of the push rod driving motor; comparing the actual load with the maximum allowable load; and under the condition that the actual load is larger than the maximum allowable load, the full-electric high-altitude operation equipment is forbidden to act. The adaptive capacity of the full-electric high-altitude operation equipment to different environments can be improved.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a load control method, device and all-electric high-altitude operation equipment. Background technique [0002] Since all-electric aerial work equipment usually needs to bear a certain load during operation, it is extremely important to determine the rated working load of all-electric aerial work equipment. In the prior art, to determine the rated working load of the all-electric aerial work equipment, the usual method is to calculate the maximum tipping moment of the all-electric aerial work equipment under the current working conditions, thereby calculating the maximum load, or on the basis of the maximum load Further consider the safety factor to determine the rated working load of the all-electric aerial work equipment. However, the actual application environment of all-electric aerial work equipment is varied and complex. The above method does not take into account the ...
