Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ballastless track construction, in particular to an automatic sleeper separation platform. Background Art
[0002] Railway track construction mainly includes direct laying method, replacement laying method and track arrangement method, among which the track arrangement method is the most commonly used. The main construction equipment used in the track arrangement method is the sleeper platform, which includes the sleeper platform main beam, track and sleeper trolley for placing sleepers. The track is set on the sleeper platform main beam. There are multiple sleeper trolleys, and each sleeper trolley is connected and arranged on the track in sequence through hinges. Before construction, the sleepers are installed on each sleeper trolley by manual cooperation with the sleeper hoist. After installation, the sleeper trolley at the end is pulled, and the hinge is gradually opened until it is fully opened. After each sleeper trolley moves into place, the track is installed on the sleeper, and then the track and sleeper are hoisted to the working position by a special hoist to increase work efficiency. However, the design method of the existing sleeper platform still has the following defects:
[0003] 1. The distance between each sleeper trolley is fixed, which is determined by the horizontal length after the hinge is fully opened. Therefore, this type of sleeper platform can only be used on the rail frame with a specified sleeper spacing, which has limitations in use;
[0004] 2. The spacing of the limit structure cannot be changed, but the width of the pillow blocks in different regions will vary slightly. When sending to different regions, the appropriate limit structure must be temporarily processed according to the on-site conditions, which leads to slow delivery time;
[0005] 3. When separating the pillows, you need to observe the spacing between the trolleys several times and check with the naked eye whether they are arranged in place. Not only can they not be arranged in place at one time, resulting in low efficiency, but the spacing between the pillow blocks will also be inaccurately controlled. Utility Model Content

[0013] Preferably, there are several load-bearing and traction trolleys, which are supported on the running rails by four steel wheels and move horizontally along the direction of the running rails.

[0017] 2. The automatic pillow separation platform has the effect of changing the spacing of the limiting structures to adapt to pillow blocks in different regions through the setting of the limiting structures. The limiting structures can be slid through the waist-shaped holes on both sides of the waist-shaped hole bottom plate below the limiting structure, and the spacing between the two limiting structures can be changed to adapt to pillow blocks in different regions.
[0018] 3. The automatic pillow separation platform, through the coordinated setting of the transmission rack and the traction device, has the effect of one-time placement of pillows with high efficiency and high precision. Since the traction device pulls the load-bearing traction trolley through the meshing transmission of the gear rack with high transmission precision, the position of the traction device relative to the transmission rack can be controlled by controlling the rotation angle of the gear. Therefore, it only needs to set the number of revolutions of the motor to drive the traction device to the required position at one time and the stop position is the same each time, thereby achieving one-time placement of pillows with high efficiency and high precision.
