Description
Technical field
The present invention relates to technical field of rail traffic, be specifically related to a kind of multi-function test stand for the bogie of car.
Background technology
In technical field of rail traffic, after the bogie of car is assembled, for ensureing service property (quality) and security performance, all need carry out static test, running adaptation to bogie and weigh, to test property indices, in static test, test its various performance parameters by applying certain static load to bogie; Running adaptation is then two friction pulleys by one in front and one in back contacting with wheel rim, and using one of them friction pulley as driving wheel band motor car wheel, running-in characteristic is tested in running.
On current market at home, static test, running adaptation and weighing all separately carries out, and needs to use crane for hoisting bogie, considerably increase workload and handling risk thus during test transfer, and the floor area of testing equipment is comparatively large, and equipment foundation of civil work construction work amount is large.
Summary of the invention
The present invention aims to provide one effectively can save space, and reduce handling workload, the bogie of car multi-function test stand of increasing work efficiency, integrates static-load testing device, running test device and function of weighing.
For this reason, the technical solution adopted in the present invention is: a kind of bogie of car multi-function test stand, comprises base, and is installed on static-load testing device, running test device and the lifting support system on base; Described static-load testing device comprises portal frame, hold-down devices and fixing rail, described hold-down devices can move up and down along portal frame, hold-down devices to be positioned at before and after the bogie of car directly over middle position, described fixing rail is arranged on base, and to be positioned at bottom wheel position in the outer part, the top of fixing rail is used for the lateral wheel tread of support vehicle bogie, is provided with pressure transducer in the rail groove of each fixing rail; Described running test device comprises running-in system and elevating mechanism, described running-in system to be positioned at bottom wheel position in the inner part, and realize highly regulating by the described elevating mechanism be arranged on base, the friction pulley of described running-in system is positioned at immediately below wheel bottom inside wheel rim; Each wheel of the bogie of car is equipped with a fixing rail and a running test device, and described lifting support system is positioned at immediately below bogie of car barycenter.
Preferred as such scheme, described lifting support system is made up of four lifting supports, and these four lifting supports are in rectangular layout immediately below bogie of car barycenter.
Beneficial effect of the present invention: static-load testing device, running test device and function of weighing are integrated in one, effectively save space, crane is no longer needed to carry out transfer, greatly reduce handling workload, improve work efficiency and equipment security of operation, and static-load testing device and the integrated setting of running test device make process layout more reasonable, and inspection and maintenance is convenient, efficient.

Fig. 1 is the state of the present invention when running adaptation.
Fig. 2 is the B portion enlarged drawing of Fig. 1.
Fig. 3 is the left view of Fig. 1.
Fig. 4 is the state of the present invention when static test.

Embodiment
Below by embodiment also by reference to the accompanying drawings, the invention will be further described:
Shown in composition graphs 1-Fig. 3, a kind of bogie of car multi-function test stand, primarily of base 1, and static-load testing device, running test device and the lifting support system 8 be installed on base 1 forms.
Shown in composition graphs 1-Fig. 3, Fig. 5, static-load testing device forms primarily of portal frame 2, hold-down devices 4 and fixing rail 5.Hold-down devices 4 can move up and down along portal frame 2, and hold-down devices 4 is positioned at before and after bogie of car A directly over middle position, is exerted pressure by hold-down devices 4 couples of bogie of car A.Fixing rail 5 is arranged on base 1, and to be positioned at bottom wheel 3 position in the outer part, the top of fixing rail 5 be used for support vehicle bogie A wheel 3 outside tread, each wheel 3 of bogie of car A is equipped with a fixing rail 5, Figure 4 shows that state during static test.
Be provided with pressure transducer in the rail groove of each fixing rail 5, when weighing, hold-down devices 4 moves up and leaves bogie of car A, Figure 5 shows that state when weighing.
Shown in composition graphs 1-Fig. 3, running test device forms primarily of running-in system 6 and elevating mechanism 7, running-in system 6 to be positioned at bottom wheel 3 position in the inner part, and realize highly regulating by the elevating mechanism 7 be arranged on base 1, the friction pulley of running-in system 6 is positioned at immediately below wheel 3 bottom inside wheel rim.Each wheel 3 of bogie of car A is equipped with a running test device.Running-in system 6 regulates height by elevating mechanism 7, and its extreme higher position is higher than fixing rail 5, and extreme lower position is lower than fixing rail 5.
As shown in Figure 3, running-in system 6 is provided with two friction pulleys, is positioned at immediately below wheel 3 bottom inside wheel rim, arranges in triangle disposition with wheel 3.During running adaptation, two friction pulleys one in front and one in back contact with wheel rim inside wheel 3, and one of them friction pulley is as driving wheel, and band motor car wheel 3 rotates, and wheel 3 drives another friction pulley to rotate running adaptation again.
Lifting support system 8 is positioned at immediately below bogie of car A barycenter.Preferably, lifting support system 8 is made up of four lifting supports, and these four lifting supports are in rectangular layout immediately below bogie of car A barycenter.
During static test, elevating mechanism 7 drives running-in system 6 to decline, and fixing rail 5 contacts with wheel 3 bottom outside tread, and hold-down devices 4 moves down and completes test to bogie of car A applying static load; Afterwards, hold-down devices 4 moves up, and weighs; When carrying out running adaptation, lifting support system 8 raises bogie of car A jack-up, makes bogie of car A depart from fixing rail 5, after arriving the position of setting, elevating mechanism 7 drives running-in system 6 to rise, and the friction pulley of running-in system 6 contacts with wheel 3 bottom inside wheel rim.
Static test and weighing is carried out on fixing rail 5, running adaptation carries out in the running-in system 6 of belt lifting mechanism 7, and after mainly considering that compbined test terminates, bogie of car A rolls multi-function test stand away from along fixing rail, do not need levelling and leveling, very convenient; Assuming that the rail of static test is made movable rail, and the running-in system 6 of running adaptation is made fixing, after completing compbined test, bogie of car A must get back on rail just can roll multi-function test stand away from, because rail is elevated, levelling and leveling must be carried out again, bother very much.Moreover, when needing to overhaul testing equipment and change in process of the test, only need bogie of car A jack-up by lifting support system 8, just between testing equipment and bogie of car A, service clearance has been vacateed, bogie of car A is not needed to roll testing equipment away from, keeped in repair when debugging, lifting support system 8 moves down, and has saved servicing time.Finally, when turning to running adaptation by static test, do not need bogie of car A jack-up by elevating mechanism 7 and running-in system 6, but after first bogie of car A being delivered to suitable position by lifting support system 8, again by elevating mechanism 7 by jack-up running-in system 6, improve the serviceable life of running-in system, reduce repair rate.
