Equipment and methods for laying sleepers on ballast tracks for railroad construction

摘要

A device (100, 300) for laying sleepers (102, 318A, 318B, 318C) on a ballast track bed (320) for railway construction is disclosed. This device is a main body (104, 302) having a moving mechanism (106) and a forklift (108) arranged on the first side of the main body, and lifts at least one set of sleepers above the ballast trackbed. A forklift that can be actuated to hold and a pair of pivot arms (110) movably coupled to the body, each of which is equipped with a gripper (112) and a pair of pivot arm grippers. Can be actuated to capture a set of sleepers from a forklift and move this set of sleepers from the first side of the body towards the second side of the body opposite the first side. It is provided with a pair of pivot arms (110). Further, the present apparatus includes a cradle configuration (114, 304) mounted on the second side of the main body. The moving mechanism can be actuated to move the device. A pair of elongated fixed support members act to support a set of sleepers moved from the first side of the body to the second side of the body by a pair of pivot arm grippers. The pair of movable support members can be operated to perform reciprocating motion with respect to the pair of elongated fixed support members for sequentially releasing the pair of sleepers one by one from the pair of elongated fixed support members at a time. ..
