Description

Technical Field

[0001] The present invention relates to a ballastless track construction technology, and in particular discloses an automatic laying device and method for an isolation layer of a ballastless track of a high-speed railway. Background Art

[0002] With the development of the times, the speed of high-speed trains is getting faster and faster, and the high-speed railway has higher and higher requirements for the stability and smoothness of the track. The traditional ballasted track cannot meet these requirements. Therefore, ballastless track technology came into being; ballastless track is mainly composed of track plate, self-compacting concrete layer, isolation layer and concrete base. The isolation layer is located between the track plate and the concrete base. The isolation layer usually uses geotextile, which can play the role of isolation and buffering, preventing the track plate and the base from contacting, thereby reducing vibration and friction, ensuring the stability of the track, and at the same time improving the service life of the track; before paving the isolation layer, it is necessary to ensure that there are no foreign objects and dust such as stones, steel bars, iron filings, etc. on the concrete base. The existing isolation layer is usually laid by staff, which has defects such as slow manual laying, large looseness, and contamination of geotextile.

[0003] For example, the invention with patent number CN115432518A discloses a geotextile laying and winding device for slab ballastless track construction, including a box body, a push rod fixed to the box body through two first connecting rods, a first opening opened on the box body, a box cover is rotatably connected to the first opening, two first rotating shafts are rotatably connected inside the box body, both ends of the first rotating shaft extend out of the box body and are respectively fixed with a rotating wheel, a second rotating shaft is connected to the box body through a moving component, one of the first rotating shafts is fixed with two first gears, the second rotating shaft is fixed with two second gears and a winding drum, the two second gears are respectively located at the two ends of the winding drum, and the second gear is meshed with the first gear, and a second opening is opened on the box body. When laying the isolation layer, the existing isolation layer laying device needs to first fix the isolation layer on the concrete base, and then use the mobile laying device to rotate the winder to lay the geotextile on the concrete base. However, when laying the geotextile, the staff still needs to clean the surface of the concrete base first before laying the geotextile, so the laying efficiency of the geotextile will be reduced due to the low cleaning efficiency of the staff. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an automatic laying device and method for the isolation layer of the ballastless track of a high-speed railway, so as to solve the technical problem that before laying the geotextile, it is necessary to ensure that there is no foreign matter and dust on the concrete base, so the laying efficiency of the geotextile will be reduced due to the low cleaning efficiency of the staff.

[0012] Furthermore, a baffle is provided on the third fixing frame to prevent impurities from splashing during cleaning and causing damage to people or equipment.

[0013] A method for using an automatic laying device for a high-speed railway ballastless track isolation layer comprises the following steps:

[0014] S1: First, the high-speed railway ballastless track isolation layer automated laying device is moved to the designated location, and then the geotextile is installed on the first fixed frame, and then one end of the geotextile is pulled so that both sides of the geotextile are clamped between two sets of movable columns;

[0015] S2: Then, the vertical moving device is started, which drives the second connecting frame to descend, which drives the connecting column and the fixed plate to descend, which drives the two sets of third fixed frames to descend, which drives the three sets of transmission wheels and the conveyor belt to descend until one side of the conveyor belt contacts the concrete base, and at the same time, the fixed plate drives the drive motor and the fourth transmission shaft connected thereto to descend;

[0016] S3: Rotate the movable sleeve, the movable sleeve moves on the threaded rod, the threaded rod descends on the fixed platform, and drives the air intake port to descend until the air intake port descends to a suitable position;

[0017] S4: Start the dust collection device, which sucks the dust from the air intake port into the dust collection device; start the drive motor, and the output shaft of the drive motor drives the fourth transmission shaft to rotate through the coupling, and the fourth transmission shaft drives the fifth spur gear and the transmission wheel to rotate, and the transmission wheel cooperates with the other two sets of transmission wheels to drive the conveyor belt to rotate, and through the engagement of the two sets of fifth spur gears, the other set of conveyor belts also rotates to clean the impurities on the concrete base.

[0018] S5: Start the four-wheel traveling device, drive the first spur gear to rotate through the rotating shaft, the first spur gear drives the second spur gear to rotate, the second spur gear drives the first bevel gear to rotate, the first bevel gear drives two sets of second bevel gears to rotate, one set of second bevel gears drives the third bevel gear and the third spur gear to rotate, the third spur gear drives the fourth spur gear, the third spur gear and the fourth spur gear respectively drive two sets of movable columns to rotate, and the rotation directions are opposite, pull the geotextile out from the first fixed frame, and lay the geotextile on the concrete base.

[0019] It can quickly clean the concrete base and lay geotextiles, and can effectively avoid the contamination of the geotextiles. The delivery speed of the geotextiles is proportional to the moving speed of the four-wheel walking device, ensuring that the looseness of the geotextiles can be kept appropriate when laying, and at the same time ensuring high efficiency when laying the geotextiles.

[0020] The working principle and beneficial effects of this solution are:

[0021] When in use, first move the ballastless track isolation layer automatic laying device to the designated position through the four-wheel walking device, while ensuring that the cleaning mechanism is at the front end and the paving mechanism is at the rear end, and then install the geotextile, and then start the dust suction mechanism and the cleaning mechanism to clean the concrete base to ensure that the concrete base meets the requirements for paving the geotextile, and then start the four-wheel walking device, the four-wheel walking device drives the paving mechanism to run, and the paving mechanism lays the geotextile on the concrete base. The speed at which the paving mechanism sends out the geotextile is proportional to the moving speed of the four-wheel walking device, which can ensure that no matter what the moving speed of the four-wheel walking device is, the paving mechanism can send out the appropriate geotextile and can quickly lay the geotextile on the concrete base, thereby improving the laying efficiency of the geotextile.

[0022] When the paving mechanism is no longer needed, the hydraulic cylinder is activated, and the telescopic end of the hydraulic cylinder drives the first connecting frame to retract. The first connecting frame drives the second spur gear to move through two sets of U-shaped blocks. The second spur gear drives the first transmission shaft and the first bevel gear to move, so that the second spur gear and the first bevel gear are separated from the first spur gear and the second bevel gear respectively. At this time, the paving mechanism is separated from the four-wheel travel device. When the paving mechanism is needed to operate, it is first necessary to ensure that the four-wheel travel device remains stationary, and then the hydraulic rod is activated. The hydraulic rod moves the second spur gear, the first transmission shaft, and the first bevel gear to the initial position. At this time, the second spur gear and the first bevel gear are meshed with the first spur gear and the second bevel gear respectively. Whether the paving mechanism is connected to the four-wheel travel device can be controlled by separating the components. BRIEF DESCRIPTION OF THE DRAWINGS
