Description
Technical field
The utility model relates to a kind of hydraulic circulation charger, belongs to railway construction ballast track bed detection technique field.
Background technology
For a long time, in test and research process for track structure characteristic and operation conditions, the simulation of railroad train operating load is a difficult problem.Owing to being subject to the restriction of the factors such as physical environment, place, real train operation Load Simulation is difficult to realize, how by effective approach, to simulate the running status of train on rail, major issue urgently to be resolved hurrily, the outstanding knotty problem running in the on-the-spot test of Ye Shi enterprise and scientific research process.
In practice, moving triaxial test, wheel load drop test have application in the test of track structure, Tie Ke institute once set paddy etc. and set up single hydraulic jack CYCLIC LOADING simulation train load, cannot represent real load action situation, also have the operation that adopts single hydraulic jack simulation loop loading procedure in casing test, but all there is defect in these structures.
Therefore be necessary to change existing loading mode, by new mode, solve the problem of modelling of train operation load.
Summary of the invention
The utility model aims to provide a kind of hydraulic circulation charger, by research technique, realizes simulation train operation load, solves the problem of modelling of load in railway track structure test, testing process.
The utility model hydraulic circulation charger comprises support 1 and three groups of above load maintainers, load maintainer is arranged on support 1 with parallel way, wherein load maintainer comprises pedestal 2, hydraulic jack 3, wedge 4, loading beam 5, split pin 7, oil cylinder 8, bearing pin 9, pedestal 2 is welded on support 1, hydraulic jack 3 is fixedly connected with pedestal by bolt, wedge is connected with the earrings 8 of hydraulic jack by bearing pin 9, split pin 7 penetrates pin-and-hole axial restraint wedge 4 on bearing pin 9, and loading beam horizontal stroke 5 crosses and is fixed on wedge 4; Described loading beam 5 can slide on wedge 4.
The installation interval of described load maintainer on support 1 is the integral multiple of sleeper pitch on the section of track.
Principle of work of the present utility model: during work, primer fluid press pump, by three hydraulic jacks of PLC programmed control, with sequence of movement, the working pressure of setting, the operating frequency of setting set, move, with the equally spaced priority time, carry out and load action in order.
The beneficial effects of the utility model are: utilize hydraulic principle to realize the simulation of railroad train load to rail effect, the setting sequence of movement of hydraulic jack and true train axle are heavily very approaching to the effect situation of track, with succinct structure, realize the simulation to train axle heavy load, hydraulic structure makes axle heavily be easy to adjust.The utility model is applicable to the simulation that a prose style free from parallelism has the middle train operation load of common railway, high-speed railway and other rail lines such as quarrel railway ballast, nothing quarrel railway ballast, whole railway ballast.
The utlity model has simple in structurely, easy to operate, pressure adjustment is easy, the advantage that operating cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the utility model is faced structural representation;

In figure: 1 is support, 2 is pedestal, and 3 is hydraulic jack, and 4 is wedge, and 5 is loading beam, and 6 is rail, and 7 is split pin, and 8 is oil cylinder, and 9 is bearing pin.
Embodiment
Below by drawings and Examples, the utility model is described in further detail, but protection domain of the present utility model is not limited to described content.
Embodiment 1: as Figure 1-3, this hydraulic circulation charger comprises support 1 and three groups of above load maintainers, load maintainer is arranged on support 1 with parallel way, wherein load maintainer comprises pedestal 2, hydraulic jack 3, wedge 4, loading beam 5, split pin 7, oil cylinder 8, bearing pin 9, pedestal 2 is welded on support 1, hydraulic jack 3 is fixedly connected with pedestal 2 by bolt, wedge is connected with oil cylinder 8 by bearing pin 9, split pin 7 penetrates pin-and-hole axial restraint wedge 4 on bearing pin 9, and loading beam horizontal stroke 5 crosses and is fixed on wedge 4.
During hydraulic jack 3 work, first hydraulic jack moves downward, be depressed on rail 6 and carry out and load action, after unloading, then second hydraulic jack starts to move downward execution loading action, after unloading, then the 3rd hydraulic jack starts to move downward execution loading action, order is until all hydraulic cylinder action completes once presses down, loads, unloads according to this, and a CYCLIC LOADING process completes, and next repeats the motion during through rail with simulation railroad train of this CYCLIC LOADING process.
The installation interval of described load maintainer on support 1 is the integral multiple of sleeper pitch on the section of track.
The working pressure size of described load maintainer hydraulic jack 3 is with loading force curvilinear motion, and the operating frequency of hydraulic jack 3 matches with the speed of simulation train.
Described loading beam 5 can slide on wedge 4.
Embodiment 2: this hydraulic circulation charger comprises support 1 and three groups of above load maintainers, load maintainer is arranged on support 1 with parallel way, wherein load maintainer comprises pedestal 2, hydraulic jack 3, wedge 4, loading beam 5, split pin 7, oil cylinder 8, bearing pin 9, pedestal 2 is welded on support 1, hydraulic jack 3 is fixedly connected with pedestal 2 by bolt, wedge is connected with oil cylinder 8 by bearing pin 9, split pin 7 penetrates pin-and-hole axial restraint wedge 4 on bearing pin 9, and loading beam horizontal stroke 5 crosses and is fixed on wedge 4.
During hydraulic jack 3 work, first hydraulic jack moves downward, be depressed on rail 6 and carry out and load action, in the time of first hydraulic jack unloading, second hydraulic jack starts to move downward execution loading action, in the time of second hydraulic jack unloading, the 3rd hydraulic jack starts to move downward execution loading action, order is until all hydraulic cylinder action completes once presses down, loads, unloads according to this, a CYCLIC LOADING process completes, the motion while next repeating this CYCLIC LOADING process with simulation railroad train process rail.
The working pressure size of described load maintainer hydraulic jack 3 is with loading force curvilinear motion, and the operating frequency of hydraulic jack 3 matches with the speed of simulation train.
