Sleeper changing method for greatly improving sleeper replacing efficiency and eliminating personal potential safety hazards

Abstract

The invention relates to a sleeper chaging method for greatly improving sleeper replacing efficiency and eliminating personal potential safety hazards, and relates to the technical field of railway construction. The method comprises the following steps that two cooperation personnel are arranged in advance to check or wash new I-type, II-type and III-type cement pillow screws to be replaced, then prepared spring boxes are installed, and spring washer nuts are tightened; meanwhile, two cooperation personnel are arranged to remove nuts, fasteners, elastic strips and nylon pads of the I-type old pillow, the II-type old pillow and the III-type old pillow or the damaged pillow which are prepared to be replaced; after a skylight point is started, a manipulator of the multifunctional operation vehicle normally rags ballast and opens an opening under the command of a safety commander, and an old pillow is pulled out. According to the sleeper changing method for greatly improving the sleeper changing efficiency and eliminating the personal safety hazards, the transition product spring box is utilized, sleeper changing mechanization can be achieved, the sleeper changing efficiency is greatly improved, and meanwhile the personal safety hazards of cooperation personnel are thoroughly eliminated.

Description

technical field [0001] The invention relates to the technical field of railway construction, in particular to a pillow changing method for greatly improving the efficiency of pillow changing and eliminating hidden dangers of personal safety. Background technique [0002] The railways built before the 1990s in my country basically used 67-type fasteners and WJ-type elastic fasteners. Now it is the time for a large number of pillow replacements; because the designers did not consider the use of mechanized pillow replacement operations in the future. Therefore, in the current process of changing pillows, only parts of mechanization can be used, and the installation of a complete set of fastener systems such as rubber pads, fasteners, nylon pads and spring bars is relatively complicated and difficult to complete by mechanization. Sea Tactics". Therefore, only semi-mechanization can be realized in the process of changing pillows, which not only affects the working efficiency of ...
