Embodiment

[0020] Such as figure 1 As shown, the pitch mechanism of the stacker-reclaimer used in this embodiment includes a slewing mechanism 3 supported on the traveling wheel 4, a pitch cylinder 5 supported on the slewing mechanism 3, a cantilever beam 6, and a counterweight arm 2, which are mounted on the counterweight The counterweight 1 of the arm 2 is mounted on the bucket wheel 7 of the cantilever beam 6 . Wherein, a pressure detection sensor is installed in the rodless cavity and the rod cavity of the hydraulic oil cylinder respectively, and the output terminal of the sensor signal is connected with a programmable controller.

[0021] The rapid detection method of the stacker-reclaimer balance weight in this embodiment includes:

[0022] The first step is to lower the cantilever beam bucket wheel of the stacker-reclaimer to the lower limit position in the no-load state; at this time, according to the working pressure P of the rodless cavity of the hydraulic cylinder 无 and rod ...

Abstract

The invention relates to a rapid detecting method of balance weight distribution of a material piling and taking machine. The method includes the steps that the output load of an oil cylinder output load in an limit position under an unloaded state is determined, ground contact pressure of a cantilever beam bucket wheel is determined, and by judging whether the ground contact pressure is within a preset value range or not, whether the weight distribution is reasonable or not is judged. The rapid detecting method of balance weight distribution of the material piling and taking machine is convenient and easy to operate, capable of quickly determining whether the balance weight distribution is reasonable or not, high in reliability, and free of support of professional theory and technology and large scale equipment, and labor and cost are saved.

Description

technical field [0001] The invention relates to a rapid detection method for the balance weight of a stacker-reclaimer, which is suitable for quickly judging whether the balance weight of the stacker-reclaimer is reasonable. Background technique [0002] According to the applicant's understanding, the arm-type bucket wheel stacker-reclaimer is a large-scale efficient stacker-reclaimer, and it is a track-type loading and unloading machine that can use the bucket wheel to continuously take materials and use the belt conveyor on the machine to continuously stack materials. [0003] Usually, when installing the stacker-reclaimer, the number of balance weights of the stacker-reclaimer is initially determined according to the design requirements. In the daily production process, due to local structural changes, bucket wheel accumulation and other reasons, the pitching mechanism of the feeder will be unbalanced, causing uneven force on the slewing bearing of the feeder, resulting i...
