Problems solved by technology
In recent years, with the development of track science, many tracks use support blocks instead of long sleepers. During the test, because a support block can only install a set of fasteners and the support block is small in size and light in weight, the fasteners are not The installation and adjustment have brought troubles. It is difficult to adjust the two support blocks to the same height and plane, and it is also difficult to maintain a certain distance. Even after the assembly is completed, the support blocks will move under the action of the test force during the test, resulting in Inaccurate results

The invention discloses an adjustable-height track fastener fatigue testing device, comprising two side positioning plates, two end positioning plates, two central positioning plates, four pressing plates, two support blocks, multiple end positioning bolts and multiple central positioning bolts. The two side positioning plates and the two end positioning plates form a closed rectangular body; thecentral positioning plates, the side positioning plates and the end positioning plates form two support block grooves for holding the support blocks; the four pressing plates are inserted in the support block grooves through pressing plate insert slots by being perpendicular to the side positioning plates; the side positioning plates located within the range of the support block grooves are provided with transversely height adjusting holes, and pads can be mounted in the height adjusting holes. The adjustable-height track fastener fatigue testing device has the advantages that mounting and testing are facilitated since mounting states of long sleepers are simulated by respectively mounting the support blocks at two ends of the positioning tooling and adjusting position and height of the support blocks in the positioning tooling.
Description
technical field [0001] The invention relates to a test device, in particular to a height-adjustable fatigue test device for rail fasteners. Background technique [0002] As a key component of the track structure, railway fasteners play an important role in maintaining the stability of the track structure. During the fastener assembly fatigue test, it is an important test item to judge the long-term performance of the fastener. When performing the fastener assembly fatigue test, the fastener needs to be Assembled in the laboratory to the state of use, that is, two sets of fasteners (or four sets of fasteners) are kept at the same height, level and at a certain distance. In recent years, with the development of track science, many tracks use support blocks instead of long sleepers. During the test, because a support block can only install a set of fasteners and the support block is small in size and light in weight, the fasteners are not The installation and adjustment have b...
