Abstract
The utility model relates to a kind of test complex for urban rail transit vehicles bogie, comprises worktable, and the static-load testing device be installed on worktable and running test device; Static-load testing device comprises two root posts, static pressure bracing frame and hold-down devices, and static pressure bracing frame is fixedly installed in the inner side bottom bogie of car wheel; Running test device comprises running-in system and elevating mechanism, and wherein running-in system is positioned at wheel bottom outside position, and installs on the table by elevating mechanism; Each wheel of the bogie of car is equipped with a static pressure bracing frame and a running test device, and hold-down devices to be positioned at before and after the bogie of car directly over middle position.Static-load testing device and running test device are integrated, effectively saves space, no longer need crane to carry out handling transfer to the bogie of car, saved cost of wheeling.
Description
Technical field
The utility model relates to technical field of rail traffic, is specifically related to a kind of test complex for urban rail transit vehicles bogie.
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 to carry out static test and running adaptation to bogie, 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 tread, 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 and running adaptation all separately carry out usually, need to use crane for hoisting bogie during test transfer, considerably increase workload and handling risk thus, and the floor area of testing equipment is larger, process layout is reasonable not, and equipment foundation of civil work construction work amount is large.
Utility model content
The utility model aims to provide one effectively can save space, reduces handling workload, the test complex for urban rail transit vehicles bogie of increasing work efficiency.
For this reason, the technical scheme that the utility model adopts is: a kind of test complex for urban rail transit vehicles bogie, comprises worktable, and the static-load testing device be installed on worktable and running test device; Described static-load testing device comprises two root posts, hold-down devices and static pressure bracing frame, described column between left and right every layout on the table, the two ends, left and right of hold-down devices are connected with each self-corresponding column respectively, the sidewall that two root posts are relative is provided with guide rail to move up and down for hold-down devices, described static pressure bracing frame is installed on the wheel bottom inside position of the bogie of car, and be fixed on bottom static pressure bracing frame on worktable, top is used for the wheel rim inside support wheel; Described running test device comprises running-in system and elevating mechanism, and described running-in system is positioned at wheel bottom outside position, and installs on the table by elevating mechanism, and the friction pulley of described running-in system is positioned at immediately below wheel bottom outside tread; Each wheel of the bogie of car is equipped with a described static pressure bracing frame and a described running test device, and described hold-down devices to be positioned at before and after the bogie of car directly over middle position.
The beneficial effects of the utility model: static-load testing device and running test device are integrated on a worktable, effectively save space, crane is no longer needed to carry out transfer, greatly reduce handling workload, increase work efficiency and equipment security of operation, and static-load testing device and the integrated setting of running test device also make process layout more reasonable, make inspection and maintenance convenient, efficient.
Accompanying drawing explanation
Fig. 1 is the trystate figure of the bogie of car on the utility model.
Fig. 2 is the left view of Fig. 1 transparent effect.
Fig. 3 is B portion enlarged drawing in Fig. 1.
Embodiment
Below by embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
Shown in composition graphs 1-Fig. 3, a kind of test complex for urban rail transit vehicles bogie, primarily of worktable 1, and the static-load testing device be installed on worktable 1 and running test device composition.
Static-load testing device comprises two root posts 2, hold-down devices 4 and static pressure bracing frame 5, two root posts 2 are between left and right every being arranged on worktable 1, the two ends, left and right of hold-down devices 4 are connected with each self-corresponding column 2 respectively, the sidewall that two root posts 2 are relative is provided with guide rail to move up and down for hold-down devices 4, static pressure bracing frame 5 is installed on wheel 3 bottom inside position, and be fixed on worktable 1 bottom static pressure bracing frame 5, top is used for the wheel rim inside support wheel 3.
Running test device comprises running-in system 6 and elevating mechanism 7, running-in system 6 is positioned at wheel 3 bottom outside position, and be arranged on worktable 1 by elevating mechanism 7, running-in system 6 regulates height by elevating mechanism 7, its extreme higher position is higher than static pressure bracing frame 5, and extreme lower position is lower than hydrostatic support frame 5.Running-in system 6 is provided with two friction pulleys, is positioned at immediately below wheel 3 bottom outside tread, arranges in triangle disposition with wheel 3.During running adaptation, two friction pulleys one in front and one in back contact with tread outside 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.
Each wheel 3 of bogie of car A is equipped with a static pressure bracing frame 5 and a running test device, and hold-down devices 4 to be positioned at before and after bogie of car A directly over middle position.During static test, the friction pulley of running-in system 6 declines, and the rail of static pressure bracing frame 5 contacts with wheel 3 bottom inside wheel rim, and hold-down devices 4 moves down and completes test to bogie of car A applying static load; When running and test, the friction pulley of running-in system 6 rises, and contacts with wheel 3 bottom outside tread.
