Abstract

The utility model provides a rail impact tester that drops into hammer, its technical scheme is that support, workstation and collateral branch hold are constituteed, and wherein the collateral branch holds and passes through welded connection with the support, plays the supporting role to the support, prevents to strike too big equipment slope that leads to of during operation and collapses, and the workstation passes through welded connection with the support, and the scaling ladder on the staff's accessible support climbs to the workstation on, carries out the maintenance and the detection of equipment. And the tester is mainly characterized in that the free-falling body motion of the hammer body reaches 12 meters.

Description

Steel rail drop hammer impact testing machine

Technical Field

The utility model relates to a hammer impact test falls, concretely relates to rail hammer impact tester falls for detect the plastic deformation ability and the performance of detecting the rail, belong to rail hammer impact tester technical field that falls.

Background

Most of the existing drop hammer impact tests adopt a manual method, a heavy hammer is hung on a hook manually each time, the hook is lifted to a certain height, the heavy hammer is enabled to do free-fall motion to perform the impact test, then an operator picks up the heavy hammer and hangs the heavy hammer on the hook again to perform the next impact test, the operation is repeated, manpower is wasted, the required impact test cannot be achieved once, the drop hammer impact test machine is partially adopted, but the ratio of the height to the weight cannot reach the national standard, so that the height of a support is reduced, the weight of the heavy hammer is increased, the service life of equipment is greatly shortened, and the safety of the equipment is greatly reduced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough of above-mentioned current instrument, provide a rail impact tester that falls into hammer, impact energy 1000J-120000J (electrodeless adjustable) to detect the plastic deformation ability and the performance of rail.

The utility model provides a rail drop hammer impact tester, its technical scheme is that support 1, workstation 2 and collateral branch holds 3 constitution, and wherein collateral branch holds 3 and support 1 and passes through welded connection, plays the supporting role to support 1, prevents to strike too big equipment slope that leads to of during operation and collapses, and workstation 2 and support 1 pass through welded connection, and the scaling ladder on the staff accessible support 1 climbs to the workstation, carries out the maintenance and the detection of equipment. The testing principle of the machine is that the actual impact rate of the batch of products can be measured by impacting a specified position of a test sample from a specified height by a drop weight with specified mass and size (when the whole batch of products are tested, the total impact damage is divided by the total impact to obtain the actual impact rate TIR, which is expressed by percentage).

The machine uses a standard hammer body of 1000 plus or minus 5kg to do free-falling motion at the height of 1-12 m, so that the hammer body is hammered on a specified position of a steel rail pattern (75 kg/m; 60 kg/m; 50kg/m), the deformation amount and the fracture condition of the pattern are detected, and whether the quality of a product is qualified or not is judged.

And the tester is mainly characterized in that the free-falling body motion of the hammer body reaches 12 meters.
