Embodiment Construction

[0021] The present invention will be further described below in conjunction with the embodiment in the accompanying drawings:

[0022] like Figure 1~3 As shown, the railway sleeper connection nut recovery treatment device provided by the present invention includes a bottom plate 1, a support frame 2, an excitation assembly 3, a primary treatment tank 4, a secondary treatment tank 5, a drying device 6 and an inclined ladder mechanism 7. The bottom plate 1 is a rectangular steel plate, which is located at the bottom of the entire railway sleeper connection nut recycling device.

[0023] The upper end of the support frame 2 is a rectangular frame structure, and parallel roller guide rails are arranged in the rectangular frame, and columns fixed to the bottom plate 1 are respectively arranged at each apex of the rectangular frame.

[0024] The vibration excitation assembly 3 includes a sliding beam 31 , a vertical multi-stage oil cylinder 32 , an excitation oil cylinder 33 , a c...

Abstract

The invention discloses a recycling treatment device for railroad sleeper connecting nuts. The recycling treatment device comprises a bottom plate, a support frame, a shock excitation assembly, a primary treatment tank, a secondary treatment tank, a spin-drying device and an inclined ladder mechanism. According to the recycling treatment device, quantities of rusted railroad sleeper connecting nuts generated during the railway track changing and ordinary maintenance processes are treated in the primary treatment tank and the secondary treatment tank which are filled with a pickling derusting solution through the shock excitation assembly, the residual derusting solution on the surfaces of the treated railroad sleeper connecting nuts is further removed through the spin-drying device, centralized treatment and reutilization of the batches of rusted railroad sleeper connecting nuts are achieved, the recycling treatment device has the advantages that recycling treatment efficiency is highand resources are saved, and the recycling treatment device is simple and reliable in overall structure, low in cost, high in adaptability and good in utilization effect, and has wide practicability.

Description

technical field [0001] The invention belongs to the technical field of railways, and in particular relates to a recovery processing device for connecting nuts of railway sleepers. Background technique [0002] Due to the long-term exposure of railway sleepers in the wild, although the sleeper connecting nuts are coated with anti-rust grease, they are still very prone to rust due to erosion by wind, rain, human excrement, etc. If the corroded nuts are not replaced in time, it will often lead to the reduction or failure of the rail buckle pressure, which will bring hidden dangers to the safe operation of the railway. At present, in the process of railway track changing and daily maintenance operations, when encountering corroded sleeper connecting nuts, the rusted sleeper connecting nuts are often directly discarded due to the troublesome derusting process, and replaced with new nuts. However, these corroded sleeper connection nuts can be reused after appropriate derusting tr...
