Steel rail drop hammer testing machine easy to disassemble, assemble and transport

Abstract

The invention discloses a steel rail drop hammer testing machine easy to disassemble, assemble and transport. The steel rail drop hammer testing machine comprises an anvil assembly (1), a steel rail supporting seat assembly (2), a steel structural frame assembly (3), a lifting hook and hammer assembly (4), a security protection cover assembly (5) and a power room assembly (6), wherein the steel rail supporting seat assembly (2) is installed on the anvil assembly (1), the steel structural frame assembly (3) is installed on the steel rail supporting seat assembly (2), and the lifting hook and hammer assembly (4) is installed inside the steel structural frame assembly (3). The steel rail drop hammer testing machine provided by the invention is easy to disassemble, assemble and transport, and is safe and reliable. The steel rail drop hammer testing machine has the advantages of simple structure, convenient disassembly, transportation and installation, low transportation cost, few secondary installation cost, small land occupation, and small damage to soil and surrounding environment.

Description

technical field [0001] The invention relates to the field of railway safety, in particular to a rail drop weight testing machine that is easy to disassemble, assemble and transfer. Background technique [0002] At present, domestic drop-weight testing machines generally cannot be disassembled and moved. The overall structure of the drop-weight machine and the protective wall are fixed construction methods. The frame of the drop-weight testing machine, the protective net and the hoist are all connected together by anchor bolts and concrete bases. , the concrete and the base are poured together, which is inconvenient to disassemble. The overall height of the drop hammer machine is generally about 10m, which is relatively high and inconvenient to transport. At the same time, in order to fix the frame and shockproof, a large amount of concrete is used, about 100 cubic meters, and the weight is about two to three hundred tons, which is impossible for conventional transportation. ...

Problems solved by technology

[0002] At present, domestic drop-weight testing machines generally cannot be disassembled and moved. The overall structure of the drop-weight machine and the protective wall are fixed construction methods. The frame of the drop-weight testing machine, the protective net and the hoist are all connected together by anchor bolts and concrete bases. , the concrete and the base are poured together, and it is inconvenient to disassemble

The overall height of the hammer drop machine is generally about 10m, which is relatively high and inconvenient to transport. At the same time, in order to fix the frame and shockproof, the amount of concrete is very large, about 100 cubic meters, and the weight is about two to three hundred tons. It cannot be transported conventionally.

[0003] The width of the existing rail support seat of the drop hammer machine is wider than that of ordinary 60 rails, generally about 155cm wide, but it cannot meet the requirements of 60R2 and other grooved rails (180cm wide at the bottom of the rail). It is also prone to smashing and overturning, which will affect the test results

[0004] The whole drop hammer machine and supporting devices are turned into indoor devices by means of fixed buildings, which prolongs the life of the drop hammer machine, but increases a lot of cost. It is more suitable for the base welding test, but it is very wasteful for the on-site rail welding test.
