Fig. 2 is one of using state figure of the present utility model (piston rod retracted mode).
Fig. 3 is using state figure bis-(piston rod stretches out state) of the present utility model.
Detailed description of the invention
In Fig. 1, the utility model comprises energy storage 11, single-action hydraulic cylinder; Energy storage 11 is provided with one for holding the inner chamber 6 of gas, and energy storage 11 is provided with for the shutoff valve 8 to energy storage inner chamber inflation/deflation, for detecting the compression indicator 9 of gas pressure value in energy storage inner chamber; Single-action hydraulic cylinder comprises cylinder barrel 3, piston rod 4, piston 7, energy storage 11 has mounting hole, the cylinder barrel 3 of single-action hydraulic cylinder is plugged in energy storage 11 inner chamber through mounting hole, piston rod 4 one end of stretching out outside cylinder barrel 3 is provided with the connector 1 for being connected with cable, the rod chamber 5 of single-action hydraulic cylinder is through air extractor vent 2 and energy storage 11 intracavity inter-connection, the rodless cavity of single-action hydraulic cylinder is provided with hydraulic fluid port 10, hydraulic fluid port 10 is connected with external hydraulic system through oil pipe, energy storage 11 is provided with fixed lug 12, and fixed lug 12 and connector 1 are oppositely arranged.Connector 1 is provided with a connecting bore.Shutoff valve 8, compression indicator 9 are relatively arranged on energy storage 11 the same side.The rodless cavity of single-action hydraulic cylinder is equipped with oil pressure indicator.
In Fig. 2, when temperature rising causes wire or catenary 13 to extend, energy storage internal pressure is constant, gas 14 cubic expansion, promotes piston through air extractor vent, drive piston rod is retracted, meanwhile, hydraulic oil is flowed out by hydraulic fluid port 10, promotes piston rod and shrinks the elongation compensating contact wire or catenary, at this moment, energy storage releases energy.In the process of piston rod reciprocating action, the tension variation of adjustment contact wire, as long as select suitable design parameters, just can meet the requirement of compensation precision.
In Fig. 3, when temperature reduction causes wire or catenary 13 to shrink, piston rod is drawn out, and energy storage internal pressure is constant, and hydraulic oil flows to rodless cavity, gas 14 volume-diminished, at this moment energy storage stored energy, and piston rod extends.
The utility model is by metal energy storage device, and the parts such as single acting oil cylinder and oil pipe form.Wherein energy storage with these assembling parts before, by charge valve, be first filled with a small amount of nitrogen, then according to calculate injection flow, be filled with hydraulic oil, after charging oil.Be filled with nitrogen again, reach the force value corresponding with the rated tension of contact wire or catenary.The connection structure of device is: metal energy storage device, and on fixing by former and later two coupling links, oil cylinder tail end is by bearing pin, and spring cotter is connected with base, and bolt is connected with base plate.Oil cylinder is connected by oil pipe with energy storage, and shutoff valve is arranged on energy storage for regulating hydraulic fluid flow rate, and oil pressure indicator charge of oil pipe is near one end of energy storage, and in order to show the pressure of this device, piston rod is connected with wire or catenary.The afterbody that air filter is arranged on oil cylinder is in piston rod crank motion, filters the air of oil cylinder rear portion turnover.This compensator is fixed by bolts on the shelf that tunnel top or contact system tower bar first set by the bolt hole on base plate, pressing of gas in energy storage is utilized to discharge and stored energy with release characteristics, and then to causing stretching or contract and automatically carrying out tension compensating of contact wire or catenary due to temperature traverse.
The utility model has small volume compared with existing tension compensator, lightweight, and structure is simple, easy for installation, simply, compensation precision is high for rated tension value and compensation range adjustment, under the short narrow obstruction clearance criterias such as tunnel, energy safety, reliably completes the auto-compensation of contact system tension force, avoids tunnel to dig, save construction costs, improve operating efficiency, reduce the interference to driving, ensure the safety of transport production.
