Description

Technical Field

[0001] The utility model relates to the technical field of track laying, in particular to a track laying device for rail transportation engineering construction. Background Art

[0002] A rail transit system is a transportation system in which operating vehicles run on specific tracks. For example, a railway transportation system is composed of trains and standard paved railways to form a certain transportation network. During the construction of the railway tracks, laying equipment is required to lay and install the sleepers.

[0003] In the prior art: Patent publication number CN202220773803.0 discloses a track laying device for rail transit engineering construction, comprising a carrier plate, wherein vertical plates are fixedly mounted on the left and right sides of the top of the carrier plate, and a first threaded rod is threadedly connected to the opposite side of the vertical plate and extends to the opposite side of the vertical plate. A movable hole is provided on the top of the carrier plate and located between the vertical plates, extending through the bottom of the carrier plate.

[0004] The above-mentioned laying device has some problems in actual operation. For example, the rails are clamped by a screw drive. However, when heavy materials such as rails are clamped for a long time, the screw thread surface is subjected to a heavy driving force for a long time, causing metal fatigue and poor transmission effect. After clamping the rails, the entire device needs to be manually moved to fine-tune the laying position, which is cumbersome to operate. For this reason, we propose a track laying device for rail transit engineering construction. Utility Model Content
