1. The utility model provides a hydraulic hoist on-line measuring system which characterized in that:

  • the hydraulic control system comprises a gate (1), a pin seat (2), a pin shaft (3), an opening and closing oil cylinder (4), an oil tank (5), an oil pump (6), a proportional overflow valve (7), a hydraulic control system (11), a first pressure gauge (8), a second pressure gauge (9), a third pressure gauge (10) and a plurality of pipelines;

    the plurality of pipelines comprise a first pipeline (11-1), a second pipeline (11-2), a third pipeline (11-3), a fourth pipeline (11-4), a fifth pipeline (6-1), a sixth pipeline (6-2), a seventh pipeline (7-1) and an eighth pipeline (7-2);

    the opening and closing oil cylinder (4) comprises an opening and closing oil cylinder piston rod (4-3) and an opening and closing oil cylinder piston (4-4), the opening and closing oil cylinder piston (4-4) is installed in a cylinder body of the opening and closing oil cylinder (4), an inner cavity of the opening and closing oil cylinder (4) is divided into an opening and closing oil cylinder lower working cavity (4-2) and an opening and closing oil cylinder upper working cavity (4-1), the upper end of the opening and closing oil cylinder piston rod (4-3) is connected with the opening and closing oil cylinder piston (4-4), the lower end of the opening and closing oil cylinder piston rod is connected with the gate (1) through a pin shaft (3) and a pin base (2), and the gate (1) is driven to move up and down by driving the opening and closing oil cylinder piston rod (4-3) and the opening and closing oil cylinder piston (4-4) to move up and down, so that the gate (1) is lifted and closed;

    an oil suction port of the oil pump (6) is communicated with the oil tank (5) through a fifth pipeline (6-1);

    an oil outlet of the oil pump (6) is communicated with an oil inlet of the hydraulic control system (11) through a first pipeline (11-1);

    an oil inlet of the proportional overflow valve (7) is communicated with a first pressure gauge (8) through a seventh pipeline (7-1);

    an oil outlet of the proportional overflow valve (7) is communicated with the oil tank (5) through an eighth pipeline (7-2);

    the seventh pipeline (7-1) is communicated with the sixth pipeline (6-2) and communicated with the first pipeline (11-1) through the sixth pipeline (6-2);

    an oil return port of the hydraulic control system (11) is communicated with the oil tank (5) through a second pipeline (11-2);

    a first oil outlet of the hydraulic control system (11) is communicated with a working cavity (4-1) on the opening and closing oil cylinder through a third pipeline (11-3);

    a second oil outlet of the hydraulic control system (11) is communicated with a lower working cavity (4-2) of the opening and closing oil cylinder through a fourth pipeline (11-4);

    the second pressure gauge (9) is arranged on the third pipeline (11-3); and

    the third pressure gauge (10) is arranged on the fourth pipeline (11-4).
