All-in-one machine system for loosening and tightening maintenances of railroad sleeper bolts and nuts

Abstract

The invention discloses an all-in-one machine system for loosening and tightening maintenances of railroad sleeper bolts and nuts in the loosening and tightening maintenance field of the railroad sleeper bolts and nuts. The all-in-one machine system comprises a digital display control system, a power system, a hydraulic loosening and tightening system, an outputting mechanism and an oil coating system; and during the process that the hydraulic loosening and tightening system is used for adjusting the bolts and nuts by the outputting mechanism, the oil coating system is used for coating oil on the threads of the bolts by the outputting mechanism. With the adoption of the all-in-one machine system for the loosening and tightening maintenances of the railroad sleeper bolts and nuts, the maintenance work time of the bolts and nuts of an existing railroad sleeper is greatly shortened, the efficiency is improved, the work strength of an operator is reduced, oil coating work is synchronized when the loosing, tightening and showing work of the bolts and nuts of the existing railroad line sleeper is performed, the existing technology is improved and optimized, accuracy control and monitoring are achieved, one-step is really finished and actual work efficiency is increased in several times.

Description

Technical field: [0001] The invention relates to the field of maintaining the tightness of bolts and nuts of railway ties, in particular to an integrated machine system for maintaining the tightness of bolts and nuts of railway ties. Background technique: [0002] According to the requirements of 4.18 of the standard content 4.18 of the "General Technical Conditions for Sleeper Bolt Motorized Wrench" issued on October 23, 2004 by the railway standard TB / T3099-2004 of the People's Republic of China: within the set working range, the torque error of the mechanical transmission wrench is not greater than ±10% of the tightening torque; the error of the tightening torque of the hydraulic transmission wrench is not greater than ±5% of the tightening torque. [0003] According to the requirements of the current "General Technical Conditions for Sleeper Bolt Motorized Wrench", it only reflects the requirements of the sleeper bolt motorized wrench for loosening, tightening and displa...

AI Technical Summary

Problems solved by technology

[0004] Since the existing equipment only includes the functions of loosening, tightening, and displaying, and the requirements for anti-rust and oiling of bolts and nuts of the actual railway line sleeper, the actual oiling operation requires manual oiling operations or additional independent oiling machinery to complete , in the existing maintenance operation, the bolts and nuts must be completely removed first, and then manually oiled or oiled with special oiling equipment, and finally the steps of tightening the bolts again are relatively cumbersome. In addition, the display mechanism of the existing equipment uses a hydraulic gauge, which requires Convert the pressure into torque, the error is large, the output torque is inaccurate, and it is extremely inconvenient to operate

The above status quo has led to the defects of low efficiency of repair and maintenance of sleeper bolts and nuts and high fatigue strength of personnel
