[0017] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a retractable laser ultrasonic dual-control leveling full-width bridge deck paver of the utility model in conjunction with the accompanying drawings.

[0018] like Figure 1 and Figure 2 As shown: a retractable laser ultrasonic dual-control leveling full-width bridge deck paver, including a main truss 9 and a mobile truss 10. The main truss 9 is assembled from a number of standard section trusses. A slide 2 is installed at the top of both ends of the main truss 9 along the length direction. The mobile truss 10 is connected to the main truss 9 through the slide 2. A hydraulic telescopic device 1 is connected between the main truss 9 and the mobile truss 10. Under the action of the hydraulic telescopic device 1, the mobile truss 10 can move horizontally on the main truss 9, thereby achieving the purpose of adjusting the length of the whole machine. Connection holes are arranged at intervals on the main truss 9 and the mobile truss 10. In the case of long-term operation, the mobile truss 10 is bolted and locked to the main truss 9 by bolts to avoid damaging the slide structure.

[0019] A traveling device 3 is installed on the end side of the mobile truss 10, and the traveling device 3 is connected to the mobile truss 10 through a hydraulic lifting device 8. In the guardrail section, the traveling device 3 adopts a grooved wheel type traveling device, which is supported on the track 4 laid on the top surface of the guardrail. When the guardrail is not constructed, it uses rubber wheels to travel, which can cope with bridge deck paving under different conditions. The hydraulic lifting device 8 is connected to the laser and ultrasonic dual control device 5, and rises or falls after receiving the signal of the laser and ultrasonic dual control device 5, and realizes automatic adjustment of the elevation through the laser and ultrasonic dual control device 5, thereby realizing the height adjustment of the whole machine.

[0020] A fixed scraper 6 and a fixed roller 11 are arranged below the main truss 9. A retractable adjustment scraper 7 is installed at both ends of the fixed scraper 6. The adjustment scraper 7 has a retractable function and can change its length. Similarly, an adjustment roller with a retractable function is also installed at both ends of the fixed roller 11. The retractable function of the scraper and roller can ensure that the length of the whole machine changes in the same manner. Specifically, the length of the fixed scraper 6 and the fixed roller 11 is equal to the length of the main truss 9, and the length of the adjustment scraper 7 and the adjustment roller is equal to the length of the mobile truss 10. The adjustment scraper 7 is connected to the ends of the fixed scraper 6 by a hydraulic telescopic rod, so that it has a retractable function and can change its length to achieve the same width as the bridge deck. The non-standard section roller parts at both ends of the fixed roller 11 are connected by a hydraulic telescopic rod, and also use a roller with a retractable function, which can be adjusted and changed in length. In addition, the adjustment scraper 7 and the adjustment roller can also be staggered with the fixed scraper 6 and the fixed roller by a certain distance, and can be retracted independently to ensure that the width of the bridge deck is covered.

[0021] During the on-site construction process, according to the width of the bridge deck, appropriate standard section trusses and scrapers and rollers of corresponding lengths are configured. If there is an extra section of truss and the length of the whole machine is too long, this section of truss is reduced and the mobile truss 10 is used for adjustment. Under the action of the hydraulic telescopic device 1, the mobile truss 10 is moved and telescoped on the main truss 9 to a length that is suitable for the width of the bridge deck. Then, the mobile truss 10 is connected and locked to the main truss 9 with bolts, and the scraper and roller are subjected to the same steps to make them suitable for the width of the bridge deck.

[0022] For bridges with gradually changing widths in the project, especially at the transition section between the bridge and the ramp, for example, where the beam width gradually changes from 15.5m to 24.35m, segmented construction is adopted. After the paver is assembled to a width suitable for 15.5m, construction is carried out forward. During the movement, the truss 10, scraper, and roller are extended by the telescopic function to extend the overall length of the truss, scraper, and roller until they are extended to the maximum working width. Then, construction is stopped, construction joints are set, and the construction width of the paver is increased again by adding standard sections. The maximum construction width can reach 25m.

In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
