[0002] In recent years, with the rapid development of my country's high-speed railways, passenger dedicated lines and urban rail transportation, ballastless tracks have been widely used. However, their laying requires high precision and is difficult. Considering factors such as uneven road surfaces and bridges and tunnels on the line, general cranes or traditional gantry cranes are used for track laying.
[0003] The existing track laying equipment for urban rail transit makes it difficult to complete track laying and accurate positioning in a small space. Since the rails are prone to shaking during transportation and it is difficult for workers to move the rails during transportation, it is easy for workers to position the rails inaccurately, resulting in a decrease in the accuracy of track laying and affecting the quality of track laying.

[0006] In a preferred embodiment of the utility model, the clamping assembly includes a fixing ring, a supporting ring, a left clamping plate, a right clamping plate and a roller. The bottoms of the two sliding rods are fixedly connected to the fixing rings. Two supporting rings are placed in the two fixing rings. The two supporting rings on the same fixing ring form a group. One of the supporting rings in each group is rotatably connected to the left clamping plate, and the other supporting ring is rotatably connected to the right clamping plate. The left clamping plate and the right clamping plate located on the same side are rotatably connected, and the lower parts of the left clamping plate and the right clamping plate are rotatably connected to two rollers.
[0007] In a preferred embodiment of the utility model, the anti-sway assembly includes a fixed frame, a limit rod and a return spring, the lower parts of the two sliding rods are fixedly connected to the fixed frame, the lower part of the fixed frame is slidably connected to two limit rods, and a return spring is connected between the two limit rods and the fixed frame, one of the limit rods is in contact with the left clamping plate, and the other limit rod is in contact with the right clamping plate.
[0008] In a preferred embodiment of the utility model, it also includes support rods and limit plates. Two support rods are fixedly connected to both sides of the two sliders.

[0009] In a preferred embodiment of the present utility model, an inclined surface is provided in the middle of the limiting plate, and the limiting plate provides guidance for the limiting rod.
[0010] The beneficial effects of the utility model are as follows: 1. In actual use, workers need to move the device to the place where the rails need to be laid, and the workers start the two electric push rods at the same time. The extension of the telescopic rod of the electric push rod will drive the sliding rod, the fixed ring, and the support ring to move upward. The upward movement of the support ring will drive the left clamping plate, the right clamping plate, the roller and the rail to move upward. The worker pulls the push rod to move, and the movement of the push rod will drive the sliding block, the electric push rod and the sliding rod to move. The limit rod will limit the left clamping plate and the right clamping plate on the two groups of fixed rings respectively. Under the action of the reset spring, the limit rod can reduce the shaking of the left clamping plate and the right clamping plate during the movement. The rail can be stably transported to the top of the laying place, so that the workers can judge the laying position more accurately, thereby improving the accuracy of laying the rails.
[0011] 2. The downward movement of the sliding rod will drive the left clamping plate, the right clamping plate, the roller, the limit rod and the rail to move downward. The downward movement of the limit rod will move along the inclined surface of the limit plate. When the limit rod moves downward to the bottom, the limit rod is limited by the limit plate, and the left clamping plate and the right clamping plate on the same side will be clamped by the two limit plates, thereby improving the stability of the rail between the left clamping plate and the right clamping plate. When the workers push the rails, the rollers can reduce the shaking caused by the rails being pushed, so that the workers can move the rails more easily and adjust the position of the rails, thereby laying the rails more accurately.
