Embodiment 1

[0025] Please refer to figure 1 , the crane operating condition query system in this embodiment includes a first input unit, a second input unit, a third input unit and a comparison processing unit.

[0026] Wherein, the first input unit is used for the user to input the target weight (the weight of the hoisting object); the second input unit is used for the user to input the target range (the distance between the hoisting object and the center of gravity of the crane); the third input unit is used for the The user inputs the target height (the hoisting height of the hoisting object); the comparison processing unit is connected to the signal of the first input unit, the second input unit and the third input unit, and is used to compare the target weight, target amplitude, and target height with the crane performance table The hoisting weight, hoisting range, and hoisting height are compared, and the working conditions in which the hoisting weight is greater than or equal to th...

Embodiment 2

[0031] like figure 2 As shown, the second embodiment includes the first input unit, the second input unit, the third input unit and the comparison processing unit described in the first embodiment, the difference is that it also includes a comparison calculation unit, a first sorting unit , the hoisting calculation unit, the second sorting unit and the third sorting unit.

[0032] Wherein, the comparison calculation unit is connected to the comparison processing unit for comparing the listed working conditions with the current working conditions of the crane, and calculating the movement stroke required to switch from the current working condition to the listed working conditions ; The first sorting unit is connected with the signal comparison calculation unit for sorting the listed working conditions according to the size of the motion stroke from small to large; the hoisting weight calculation unit is connected with the comparison processing unit signal and used for calcula...

Embodiment 3

[0036] like image 3 As shown, the third embodiment includes the first input unit described in the second embodiment, the second input unit, the third input unit, the comparison processing unit, the comparison calculation unit, the first sorting unit, the hoisting weight calculation unit, the second The sorting unit and the third sorting unit also include a fourth input unit, a fifth input unit, a current working condition detection unit and a selection execution unit.

[0037] Wherein, the current working condition detection unit is signal-connected with the comparison processing unit, and is used to detect the status of the outrigger, the counterweight, the main arm and / or the auxiliary arm. The fourth input unit is signal-connected to the comparison processing unit for inputting counterweight state adjustment information, and the fifth input unit is signal-connected to the comparison processing unit for inputting outrigger state adjustment information; the comparison proces...

Abstract

The invention discloses a crane working condition inquiring system and a method. The system comprises a first input unit for obtaining a target weight, a second input unit for obtaining a target amplitude, and a comparison processing unit for comparing the target weight and the target amplitude with a lifting weight and a lifting amplitude in a crane performance table, and listing out working conditions that the lifting weight is greater than or equal to the target weight and the lifting amplitude is greater than or equal to the target amplitude. The crane working condition inquiring system and the method, provided by the invention, can compare the parameters, such as the target weight and the target amplitude of a lifting object input by a user with the crane performance table, and can list out the working conditions accordant with requirements for the user to estimate and choose; and compared with the prior art, the system and the method reduce the user manual participation time, and improve the working efficiency and the lifting safety.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a system and method for querying working conditions of a crane. Background technique [0002] As a major lifting and handling equipment, cranes are widely used in construction, manufacturing and port transportation. The hoisting performance of the crane is different under different amplitudes and different boom sections. Therefore, before the hoisting operation, for the sake of safety, the user needs to make a preliminary pre-judgment on the hoisting object. [0003] In the prior art, the operator generally obtains the approximate weight (target weight), target height, and target range of the hoisted object by the operator, and consults the crane performance table based on these parameters to determine how much counterweight to use, how much luffing angle to use, or Working condition parameters such as how long the boom can be extended, so as to be able to complete the lift...
