Double sleeper lifting tool

Abstract

The invention discloses a double-layer sleeper hoisting tool. The problems existing in current sleeper hoisting operation in a large sleeper paving base that the end parts of all sleepers are not flush and the hoisting construction cost is too high are solved. The double-layer sleeper hoisting tool comprises a horizontal sleeper left support angle steel (3) arranged at the lower ends of two left support legs and a horizontal sleeper right support angle steel (17) arranged at the lower ends of two right support legs, wherein horizontal sleeves and hinge bases are respectively fixedly arranged at the upper ends of the four inverted L-shaped support legs, front loop bars and rear loop bars are respectively fixedly welded on a front frame and a rear frame of a rectangular main bracket (11) in a lateral horizontal direction, the front loop bars are connected with the two front sleeves in a sleeving way, the rear loop bars are connected with the two rear sleeves in a sleeving manner, a hinge oscillating bar mechanism driving the inverted L-shaped support legs on the two sides to synchronously move left and right is arranged on the rectangular main bracket (11), and one to two layers of sleepers are arranged between the left support angle steel (3) and the right support angle steel (17). The double-layer sleeper hoisting tool ensures that the end parts of all the sleepers are flush when a group of sleepers are put on a flat car.

Description

technical field [0001] The invention relates to a sleeper hoisting tool used in large-scale railway track laying construction, in particular to a spreader for hoisting and transporting sleepers at a track laying base. Background technique [0002] After the construction of the railway subgrade and track bed is completed, the long rails are generally laid using the single sleeper continuous method. The laying is carried out by the track laying unit. The sleepers are stored in the track laying base. The track laying unit requires the sleepers to be placed neatly on the On the flatbed car of the track laying unit, the sleepers are required to be placed in 4 layers per car, with 28 pieces in each layer, and the ends of the sleepers should be even, so that the track laying unit can smoothly carry out the track laying operation. In the on-site construction, the existing technology is to use traditional steel wire ropes to hoist and transfer the sleepers, and transfer the sleepers ...
