Picking device used for preventing sleeper overturning

Abstract

The invention provides a picking device used for preventing the sleeper overturning. Two fixing moldboards are connected through a connecting pipe. The liftable fixing moldboards are provided with flexible moldboards. One end of each flexible moldboard is connected with the front end of each fixing moldboard, and the other end is connected with a piston rod of a flexible moldboard motion hydro-cylinder, wherein the piston rod of the flexible moldboard motion hydro-cylinder is fixed on the fixing moldboard and is used for promoting the flexible moldboard to rotate around a pin shaft so as to prevent the sleeper overturning. Two machine arms are respectively installed on a left toggle plate and a right toggle plate of a rack. A rack lift cylinder arranged in the middle of a rack shaft is connected with otic placodes. Machine arms include an upper claw and a lower claw. The end of the upper claw is arranged on the rack through a connecting shaft of the upper claw. An upper claw body is connected with each otic placode of the rack toggle plates through an upper claw clamping cylinder. The end of the lower claw is arranged on a connecting otic placode II of the lower claw cylinder of the rack toggle plate through a lower claw connecting shaft. A lower claw body is connected with a connecting otic placode I of the lower claw cylinder through a lower claw clamping cylinder, wherein the connecting otic platcode I of the lower claw cylinder is arranged on the rack toggle plate. The picking device used for preventing the sleeper overturning solves the problem that the sleeper overturns in the picking process, greatly improves the picking efficiency of the sleeper so as to improve the working efficiency of a whole overhauled train.

Description

technical field [0001] The invention relates to a railway sleeper pick-up device, in particular to a sleeper pick-up device installed on a railway line overhaul operation vehicle. Background technique [0002] At present, in the process of replacing sleepers in railway construction, when the sleepers are pried up by the moldboard and separated from the ballast bed to be picked up by the robot, due to the influence of the conditions of the ballast bed, it is often easy for the sleeper to turn over on the picking mechanism, resulting in failure to pick up the sleeper smoothly. Due to the overturning of the sleeper, manual intervention is required to process the position of the sleeper before the operation can continue, which not only increases the workload of manual assistance, but also affects the efficiency of the entire sleeper replacement operation. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art in...

[0002] At present, in the process of replacing sleepers in railway construction, when the sleepers are pried up by the moldboard and separated from the ballast bed to be picked up by the robot, due to the influence of the conditions of the ballast bed, it is often easy for the sleeper to turn over on the picking mechanism, resulting in failure to pick up the sleeper smoothly.

Due to the overturning of the sleeper, manual intervention is required to process the position of the sleeper before the operation can continue, which not only increases the workload of manual assistance, but also affects the efficiency of the entire sleeper replacement operation
