Description
Technical field
The utility model relates to a kind of guard rail that is used for rail traffic station, particularly uses the lifting mode guard rail of rail traffic station edge of table.
Background technology
Urban track traffic brings great convenience to people, but following two safety problems of the security presence of rail traffic platform: 1) an invisible catch siding is only arranged between rail traffic platform and the train rail, happen occasionally owing to crowded, careless and inadvertent, the child plays etc. falls into the incident that causes personal injury to influence normal operation in the track; 2) after train is stopped platform, exist a no small space between compartment and the platform, fall in the space, cause unnecessary damages and trouble to such an extent as to the passenger who much gets on or off the bus has been stuck in pin in the space or as small articles such as mobile phone, wallets.For avoiding the generation of above-mentioned incident, have at platform edge many fan shielded gates are installed, but this shielded gate sway is closed condition when passenger marquis's car, be opening when getting on the bus.Though this type shielding door can play buffer action, can not solve the injury and the trouble that cause because of the space that exists between compartment and the platform, and the structure bulky complex.
Summary of the invention
The purpose of this utility model provides a kind of guard rail that is used for rail traffic station, and it can move up and down, and both can erect the actv. safety curtain by track between platform when passenger marquis's car, the space in the time of can filling up train again and pull between compartment and the platform.
For achieving the above object, the utility model comprises: the nonfloating rail plate, moving door and actuating device, the nonfloating rail plate is fixed on the step of platform, moving door is between two blocks of nonfloating rail plates, each moving door is furnished with a cover actuating device, it is characterized in that also comprising: foot-operated backplate, foot-operated backplate is fixed on the top of moving door, every suit actuating device is by two multi-stage oil cylinders, check valve, back pressure valve, variable vane pump, by pass valve, change-over valve and flow regulating valve are formed, the push rod of two multi-stage oil cylinders connects foot-operated backplate respectively, the inner chamber of push rod is arranged by the oil pipe mutual conduction in two multi-stage oil cylinders, and be connected with change-over valve by oil pipe, the inner chamber of no push rod connects flow regulating valve by oil pipe in two multi-stage oil cylinders, flow regulating valve connects the mouth of change-over valve, the return opening of change-over valve connects back pressure valve, back pressure valve is by filter and fuel tank conducting, the input port of change-over valve connects the delivery port of check valve and the input port of by pass valve respectively, the delivery port of the input port link variable blade-type pump of check valve, the by pass valve delivery port is by filter and fuel tank conducting, the oil suction of variable vane pump is equipped with the oil-feed filter, and filter immerses in the fuel tank fluid.When need are closed moving door, variable vane pump starts, the change-over valve commutation, pressure oil divides two-way to enter the inner chamber of no push rod in two multi-stage oil cylinders through check valve, change-over valve, flow regulating valve, make in-oil cylinder piston actuated push rod protruding, rise to drive moving door, being in two multi-stage oil cylinders simultaneously has the oil in the push rod inner chamber to return fuel tank through change-over valve, back pressure valve and filter; When need are opened moving door, variable vane pump starts, the change-over valve commutation, pressure oil enters the inner chamber that push rod is arranged in two multi-stage oil cylinders through check valve, change-over valve, make the inside indentation of in-oil cylinder piston actuated push rod, descend to drive moving door, the oil that being in two multi-stage oil cylinders does not simultaneously have in the push rod inner chamber returns fuel tank through flow regulating valve, change-over valve, back pressure valve and filter; When moving door remained static, pressure oil returned fuel tank through check valve, change-over valve, back pressure valve and filter.
Left and right sides overbalance appears when preventing the moving door lifting; in flow regulating valve and two multi-stage oil cylinders have the oil pipe of push rod inner chamber, synchronous valve and two overload protection valves are not housed; the input port of synchronous valve connects flow regulating valve; two delivery ports connect the inner chamber that two multi-stage oil cylinders do not have push rod respectively, and two overload protection valves are connected in parallel on two multi-stage oil cylinders not to be had in the oil pipe between the delivery port of push rod inner chamber and synchronous valve.In the use, because the oil pump capacity of synchronous valve two delivery ports is identical, thereby the oil mass that can guarantee to enter two multi-stage oil cylinder inner chambers is identical, then guarantees the moving door balance lifting.When monolateral catching phenomenon occurring in moving door rises, the overload protection valve is promptly opened, and fluid flows to another multi-stage oil cylinder inner chamber through the overload protective valve, and identical with the oil pressure of guaranteeing two multi-stage oil cylinder inner chambers, moving door does not tilt.
The utility model is owing to adopt said structure, and both track was erected the actv. safety curtain between platform when passenger marquis's car, the space when filling up train again and pulling between compartment and the platform.In addition, in actuating device, adopt synchronous valve and overload protection valve, occur the unbalanced phenomenon in the left and right sides in the time of can preventing the moving door lifting.
Description of drawings:
Fig. 1, front view of the present utility model;
Fig. 2, left cutaway view of the present utility model;
The actuating device of Fig. 3, the utility model moving door.
The specific embodiment:
By shown in Figure 1, nonfloating rail plate 6 is fixed on the step 3 of platform, and moving door 1 is between two blocks of nonfloating rail plates 6, and each moving door 1 has two multi-stage oil cylinders 2 to drive.
By shown in Figure 2, foot-operated backplate 7 is fixed on the top of moving door 1, and the push rod of two multi-stage oil cylinders 2 connects foot-operated backplate 7 respectively.The width of foot-operated backplate 7 is less than the space between compartment 5 and the platform step 3.Two multi-stage oil cylinders 2 are fixed on the ground of platform by pedestal 4.
