Description
Technical field
The present invention relates to a kind of technical field of high-speed railway bridge inspection trolley, especially a kind of high-speed railway bridge inspection trolley hydraulic efficiency pressure system.
Background technology
Along with China's rapid economy development; Railway construction has also got into a rapid growth period; The quantity surge of high speed railway, railroad bridge and urban viaduct; Satisfy the efficient utilization of railway; Need to improve the detection of bridge and the efficient of maintenance activity; At present domestic bridge inspection car is difficult to satisfy the needs that railroad bridge detects development in technical merit aspect section operation speed and the reliability; It is lower that rear stability stretches out at working arm in inspection trolley operating mechanism, is difficult to guarantee inspection trolley and supervisory personnel's safety.
Summary of the invention
In order to overcome the deficiency that existing high-speed railway bridge inspection trolley working stability is lower and safety performance is low, the invention provides a kind of high-speed railway bridge inspection trolley hydraulic efficiency pressure system.
The technical solution adopted for the present invention to solve the technical problems is: a kind of high-speed railway bridge inspection trolley hydraulic efficiency pressure system; Comprise vehicle frame, Hydraulic Station, bogie truck and top car oil cylinder; Vehicle frame is provided with Hydraulic Station; Be provided with bogie truck in the vehicle frame; The bogie truck top is provided with top car oil cylinder, and Hydraulic Station is connected with top car oil cylinder.
According to another embodiment of the invention, comprise that further being provided with height between vehicle frame and the bogie truck justifies spring.
According to another embodiment of the invention, the quantity that further comprises top car oil cylinder is 8.
According to another embodiment of the invention; Comprise that further Hydraulic Station is made up of pressure port A/B, governor valve, solenoid directional control valve, reducing valve and by pass valve; Governor valve one end is connected with pressure port A/B; The other end is connected with solenoid directional control valve; Reducing valve is connected with solenoid directional control valve, and by pass valve is connected with reducing valve.
According to another embodiment of the invention, comprise that further top car oil cylinder is connected with pressure port A/B, top car oil cylinder is provided with bidirectional hydraulic lock.
The invention has the beneficial effects as follows; This high-speed railway bridge inspection trolley hydraulic efficiency pressure system is the hydraulic oil that inspection trolley operating mechanism and bogie truck blocking device top car oil cylinder provide certain pressure, flow; Each parts of Hydraulic Station adopt modular design; Drive operating mechanism and realize the different types of rridges audit function; Also improve simultaneously operating mechanism in the stability that working arm stretches out the back car load, guaranteed inspection trolley and supervisory personnel's safety.

1. vehicle frames among the figure, 2. Hydraulic Station, 3. bogie truck, 4. top car oil cylinder, 5. height circle spring.
The specific embodiment
Like Fig. 1 is structural representation of the present invention; A kind of high-speed railway bridge inspection trolley hydraulic efficiency pressure system; Comprise vehicle frame 1, Hydraulic Station 2, bogie truck 3 and top car oil cylinder 4; Vehicle frame 1 is provided with Hydraulic Station 2; Be provided with bogie truck 3 in the vehicle frame 1; Bogie truck 3 tops are provided with top car oil cylinder 4, and Hydraulic Station 2 is connected with top car oil cylinder 4, are provided with high circle spring 5 between vehicle frame 1 and the bogie truck 3.
Like Fig. 2 is the hydraulic schematic diagram of Hydraulic Station of the present invention; Hydraulic Station is made up of pressure port A/B, governor valve, solenoid directional control valve, reducing valve and by pass valve; Governor valve one end is connected with pressure port A/B; The other end is connected with solenoid directional control valve; Reducing valve is connected with solenoid directional control valve; By pass valve is connected with reducing valve, and pressure port A/B is connected with 8 top car oil cylinders, and top car oil cylinder is provided with bidirectional hydraulic lock.
During use, pressure port A/B mouth connects 8 top car oil cylinders 4, and system pressure is regulated by by pass valve and set, and is set in 200bar, and bogie truck blocking device pressure is regulated by reducing valve and set, and is set in 65bar, and governor valve is regulated the kinematic velocity of top car oil cylinder 4.Before operating mechanism's dead work; The bridge inspection car switches to operation and walks row mode; The start-up control button; Solenoid directional control valve right side electromagnet gets; Pressure oil gets into the rodless cavity of top car oil cylinder 4; Piston rod stretches out and acts on the bogie truck 3; The cylinder barrel of top car oil cylinder 4 drives vehicle frame 1 upward movement; With elasticity and bogie truck 3 inner each damping of the circle of the height between vehicle frame 1 and the bogie truck 3 spring 5 is that elasticity is eliminated; Make car load become the rigidity operation; To increase the stability that the back car load stretches out at working arm in operating mechanism, guarantee inspection trolley and supervisory personnel's safety; The inspection operation is accomplished, after working arm is regained, and the start-up control button; Electromagnetic steering valve left side electromagnet gets electric, and pressure oil gets into the rod chamber of top car oil cylinder 4, and the cylinder barrel of top car oil cylinder 4 drives vehicle frame 1 and moves downward; Blocking device is removed, and inspection trolley switches to the interval and walks the row mode high-speed cruising; Electromagnetic steering valve left and right sides electromagnet all must not when electricity, and top car oil cylinder 4 does not move, and the bidirectional hydraulic lock on the top car oil cylinder 4 guarantees that oil cylinder can be owing to action of gravity move downward, thereby guarantees traffic safety.This high-speed railway bridge inspection trolley hydraulic efficiency pressure system is the hydraulic oil that inspection trolley operating mechanism and bogie truck blocking device top car oil cylinder provide certain pressure, flow; Each parts of Hydraulic Station adopt modular design; Drive operating mechanism and realize the different types of rridges audit function; Also improve simultaneously operating mechanism in the stability that working arm stretches out the back car load, guaranteed inspection trolley and supervisory personnel's safety.
