Description

Technical Field

[0001] The utility model relates to the technical field of bridge and road construction, in particular to a base surface leveling device for bridge and road construction. Background Art

[0002] During the construction of bridges and roads, after the base surface is paved with concrete, in order to ensure the flatness of the road surface in the future, a leveling device is needed to level the base surface. For example, the patent with application number CN202021306006.9 discloses a concrete base surface leveling device for municipal highway construction, which uses a scraper to scrape and level the concrete base surface. However, after long-term use, the scraping surface of the scraper will be worn and uneven. Since the scraper in the above-mentioned device is fixedly mounted on the adjusting block, it is difficult to remove the scraper when it is necessary to replace the scraper. The replacement of the scraper is relatively troublesome. For this reason, the utility model improves a roadbed leveling device that can facilitate the replacement of the scraper. Summary of the invention

[0003] The disclosed embodiment relates to a bridge and road construction base surface leveling device, which uses a positioning socket to easily place and install a leveling scraper, making it relatively simple to remove the leveling scraper when it needs to be removed. Compared with the method of fixing the scraper blade in the comparative document, the method of the roadbed leveling device makes it easier to replace the leveling scraper.

[0004] In a first aspect, the present disclosure provides a base surface leveling device for bridge construction, specifically comprising: a base guide rail, a cylindrical docking clamp is fixedly installed on the front end of the base guide rail; a circular hole-shaped docking slot is provided at the rear end of the base guide rail; when two base guide rails are docked, the docking clamp on the rear base guide rail will be inserted into the docking slot on the front base guide rail; a leveling vehicle body is slidably installed on the base guide rail; a convenient roller is rotatably installed on the bottom of the leveling vehicle body; a push-touch rod is fixedly installed on the inner side of the leveling vehicle body by bolts.

[0005] In at least some embodiments,

[0006] A guide groove is provided on the outer side of the flat body; a transmission screw is rotatably installed inside the guide groove; the top end of the transmission screw protrudes from the top of the flat body; an operating handwheel is fixedly installed on the top of the transmission screw; a connecting sprocket is fixedly installed on the circumferential outer wall of the transmission screw; the two connecting sprockets are connected by a chain; an adjusting slider is slidably installed inside the guide groove; the adjusting slider is also connected to the transmission screw through threads.

[0007] In at least some embodiments,

[0008] A positioning card seat is fixedly installed on the inner side of the adjusting slider; a flat scraper is placed and installed inside the positioning card seat; positioning clamping columns are slidably installed on the front and rear sides of the positioning card seat; the positioning clamping columns are cylindrical structures; an embedded baffle is fixedly installed on the outer end of the positioning clamping column; the embedded baffle is a disc-shaped structure; one end of a restoring spring is embedded and installed on the inner side of the embedded baffle; the other end of the restoring spring is embedded and installed on the outer side wall of the positioning card seat.

[0009] In at least some embodiments,

[0010] When the transmission screw rotates, the transmission screw will move along the guide groove by rotating with the adjusting slider; when the adjusting slider moves downward, the adjusting slider will move downward with the positioning card seat and the leveling scraper; a transmission column is fixedly installed on the outer side of the embedded baffle; the transmission column is a cylindrical structure with an inclined structure at the bottom end; when the transmission column moves downward, the push contact rod will push the inclined surface of the transmission column.

[0011] The utility model provides a bridge construction base surface leveling device, which has the following beneficial effects:

[0012] 1. The leveling scraper in the leveling device is installed by placing it without direct fixation. Therefore, after the scraping surface of the leveling scraper is seriously damaged, the staff can directly remove the damaged leveling scraper from the positioning holder for replacement, which will not spend too much time on replacing the leveling scraper, thereby improving the convenience of replacement.

[0013] 2. When the leveling device controls the leveling scraper to descend and contact the base surface for pre-leveling work, the leveling scraper can be automatically fixed with positioning clamps to avoid affecting the leveling quality due to the leveling scraper being too loose. In this way, the leveling quality of the leveling scraper for the base surface can be guaranteed and the convenience of replacing the leveling scraper can be guaranteed.
