Pre-buried casing type sleeper hoisting device

Abstract

The invention discloses a pre-embedded casing type sleeper hoisting device, which comprises a hanger, and both sides of the bottom of the hanger are provided with tongs, and the tongs are connected to the hanger through a sling, and the tongs include a suspension ring, a first connecting piece, The second connecting piece, the first clip and the second clip, the upper end of the first connecting piece, the upper end of the second connecting piece and the lower end of the suspension ring are hinged, the upper end of the first connecting piece is hinged with the lower end of the second connecting piece, and the second connecting piece The upper end and the lower end of the first connecting piece are hinged, the first clip and the second clip are composed of an upper clip and a lower clip, and the upper clip of the first clip and the upper clip of the second clip are arranged crosswise and hinged Together, the lower clip of the first clip and the lower clip of the second clip are provided with clip teeth, and the clip teeth cooperate with the internal threads on the pre-embedded casing in the pre-buried sleeve type sleeper. The invention can increase the hoisting speed of the sleeper and reduce the number of operators, and the sleeper has a neat landing point, which can meet the loading requirement that the sleeper of a long rail laying machine must be aligned, and can ensure construction safety.

Description

technical field [0001] The invention belongs to the technical field of railway construction, and in particular relates to a hoisting device for a pre-embedded casing type sleeper. Background technique [0002] In the gradual promotion and use of CPG500 / TCM60 and other domestic and foreign long rail laying machines "single sleeper continuous laying method" to lay long steel rails in one seamless line laying process, rail materials and sleepers must be transported to the front of track laying by sleeper transport vehicles to cooperate with track laying Machine track laying work. In the operation process, the loading and unloading of rail materials and sleepers takes up most of the track laying process, and the laying points of the sleepers must be neat to ensure the speed of track laying construction and the safety of equipment. The traditional hoisting methods of sleeper hoisting devices are mostly steel wire rope at the bottom of the sleeper, clamping at the bottom of the s...

AI Technical Summary

Problems solved by technology

The traditional hoisting methods of sleeper hoisting devices are mostly steel wire rope at the bottom of the sleeper, clamping at the bottom of the sleeper, on-site anchoring or pre-tightened bolt lifting, etc. In the above methods, the assembly platform needs to be set up in advance to ensure the safety of the sleeper. The landing points are aligned front and back; on-site anchoring is not suitable for pre-embedded sleeve type sleepers; and pre-tightening anchor bolts are a great waste of human resources and take up working time, low work efficiency, and cannot achieve sleeper clamping to the landing point Neatly in place

At the same time, according to the operating speed requirements of long-rail track-laying machines, there are many deficiencies in the currently used hoisting devices, which can no longer meet the high-speed, economical and safe needs of long-rail track-laying machines.
