Description

Technical Field

[0002] At present, the continuous sleeper replacement operations on old lines abroad are mainly carried out using large-scale rail and sleeper replacement equipment. These equipment have long operation lines, large volumes, low work efficiency, difficult construction organization, long operation time, and difficult parking. In addition to this large equipment, domestic railway sleeper replacement machines that are transformed from small excavators with multi-functional sleeper grabbing devices are mostly used for construction. The efficiency of a single operation is not high, and multiple machines can be laid out and operated simultaneously to flexibly meet the requirements of operation efficiency. This mode cannot transport sleepers in one go, and at least three special constructions are required to completely complete the replacement of sleepers. The construction organization is difficult, the personnel demand is large, and there are great safety hazards. At present, the sleeper changing equipment on the market, whether it is a large-scale track and sleeper changing equipment or a sleeper changing machine modified from a small excavator, has the following defects: during construction, it is inevitable to lift or shift the track, which will damage the bed and rails; only a short distance of sleepers can be replaced at a time, and new sleepers need to be frequently transported and old rails need to be exported to meet construction needs, resulting in low construction efficiency; two sets of equipment need to be set up for laying new sleepers and recycling old sleepers, respectively, which increases the cost and the length of the entire set of sleeper changing equipment; since most of the existing sleeper changing equipment is a complete work line, as long as one of the links fails, the construction has to be stopped, and the operation can only be continued after the problematic link is repaired, delaying the construction progress.

The sleeper replacement vehicle and combined sleeper replacement unit provided in the embodiment of the present application can complete the sleeper replacement operation without destroying the old sleepers, and do not require track lifting or track shifting actions, and are suitable for the field of railway line maintenance technology.

[0004] However, there are some shortcomings in the sleeper replacement device provided by the device. When used in reality, the transported target object is difficult to fix in position, and it sways left and right and there is a risk of falling, which can easily cause unnecessary trouble, and it is more troublesome to clamp or place the target object.
