Abstract
The utility model relates to a hydraulic driving quick plane gate, which is composed of an oil cylinder which is connected with a hydraulic station, and a gate which is connected with a piston rod in the oil cylinder. After the utility model is additionally provided with an energy accumulator on the hydraulic station, and is additionally provided with a bearing between the piston rod and the gate, the oil pressure of a hydraulic system can be supplemented effectively, an oil bearing motor of the hydraulic station can be reduced or can not start to make the opening operation and the closing operation of the gate flexible. The speed regulation is balanced and reliable. The abrasion of the oil cylinder is reduced, and thereby, the service life of the utility model is extended.
Description
The utility model relates to the gate that surges.
The domestic various water supply and sewage work such as water conservancy, water power, sewerage treatment that are used for switch runner, block the gate that surges of current, are made up of Hydraulic Station, oil cylinder, gate; The switching of its gate drilled through common slide valve by hydraulic pressure and choke valve is controlled oil pressure, in-oil cylinder piston is risen or decline, thereby makes gate reach the purpose of open and close.When gate was in normally open, hydraulic system leakage needed the Oil pump electrical machinery frequent starting on the Hydraulic Station, so that give the timely repairing of hydraulic system, just can make gate keep normally open.
In addition, the suspension rod of gate and the piston rod of oil cylinder are direct-connected, because alignment error is bigger, make the axiality of gate and piston rod be difficult to guarantee, cause very quick-wearing of oil cylinder inner seal ring, cylinder body, piston, even make the piston rod distortion.Need often maintenance or change the part that weares and teares, the maintenance cost height, and maintenance difficulty is big.
The purpose of this utility model is: increasing an energy storage equipment on the Hydraulic Station and being connected with bearing between piston rod and the gate, to reduce the Oil pump electrical machinery number of starts, improve the hydraulic system pressure maintaining performance, make piston rod and gate start the flexible increase life-span.
The technical solution of the utility model is as follows:
The utility model comprises Hydraulic Station and plane gate, and the oil pipe of Hydraulic Station is connected with oil cylinder, and in-oil cylinder piston rod links to each other with gate, and its accumulator is on Hydraulic Station; Be connected with a bearing between piston rod and the gate.
Accumulator and Oil pump electrical machinery are connected on the pressure controller by oil pipe.
Be connected with one between piston rod and the gate and hang head, piston rod with hang head and be connected by screw nut, hang and gate between bearing is arranged.
When Oil pump electrical machinery was worked, the hydraulic control one-way valve of road of the pressure oil of output to the integrated package be to oil cylinder, promotes the oil cylinder piston piston rod and the gate that is attached thereto moves upward, with gate opening; Can lay in hydraulic pressure to get up to accumulator in another road, when hydraulic system pressure was raised to the upper limit force value of pressure controller, pressure controller was sent out signal and quit work by Oil pump electrical machinery.Make gate remain on normally open by accumulator.When the hydraulic system micro-leakage made system pressure reduce to pressure controller threshold pression value, pressure controller was just sent out signal by Oil pump electrical machinery work, till pressure rises to pressure controller upper limit force value.
Advantage of the present utility model is as follows:
1. because the novel accumulator that increased on Hydraulic Station of this reality has replenished the oil pressure of hydraulic system effectively, reduced the number of starts of Oil pump electrical machinery or do not started Oil pump electrical machinery, made hydraulic system stable more, reliable.
2. after having assembled bearing between piston rod and the gate, can guarantee piston rod, shutter opening and closing motion flexibly, improved equipment installation and operation precision, reduced the loss of part, improved the application life of equipment, hang the screw thread of head by the adjusting connecting portion and can regulate centre distance by trace, satisfy installation requirement.
Embodiment is further described at the utility model in conjunction with the accompanying drawings.
Fig. 1 is the utility model structural representation.
Fig. 2 is a Hydraulic Station vertical view among Fig. 1.
Fig. 3 is a partial enlarged drawing among Fig. 1.
Among Fig. 1: the oil pipe (3) on the Hydraulic Station (1) is connected with rod chamber with oil cylinder (5) rodless cavity respectively with oil pipe (4), be connected with a bearing (7) between piston rod (6) in the oil cylinder (5) and the gate (8), 2 accumulators (20) are connected on the Hydraulic Station (1) by stop valve (21), oil pipe (19), and one of them accumulator (20) is standby.
Among Fig. 2: accumulator (20) is connected on the pressure controller (9) of Hydraulic Station (1) by oil pipe (19), 2 Oil pump electrical machineries (2) are connected on the pressure controller (9) by oil pipe (10), oil pipe (3) on the Hydraulic Station (1) is connected with pressure controller (9), and oil pipe (4) is connected with hydraulic electric motor (2).
Among Fig. 3: piston rod (6) with hang the head (12) by being threaded, lock with nut (11), hang in the head (12) bearing (14) is housed, compress by gland (13), there is felt (15) sealing at bearing (14) two ends, prevent that dirt from entering, gate suspension rod (8) is connected with bearing (14) by bearing pin (16).If during gate (8) operation, if setting-up eccentricity, the deviation of bearing (14) adjusting piston bar (6) and gate (8) to guarantee gate (8) motion flexibly, makes oil cylinder and piston rod (6) not be damaged by the effect of external force, and prolongs its application life.
