Description

Technical Field

[0001] The utility model relates to the technical field of road construction obstacle clearance, in particular to a road construction obstacle clearer. Background Technique

[0002] Highway engineering refers to the work of surveying, measuring, designing, constructing, maintaining, managing, etc. of highway structures. Highway engineering structures include: subgrade, pavement, bridge, culvert, tunnel, drainage system, safety protection facilities, greening and traffic monitoring facilities, as well as houses, workshops and other service facilities used for construction, maintenance and monitoring. At present, obstacles on the road surface need to be cleared before road construction. When clearing obstacles on the road surface, a road obstacle clearer is required.

[0003] After retrieval, the existing patent application number: CN201921534180.6 discloses a road construction road obstacle clearing device. During the use of this road obstacle clearing device, although through the set auxiliary limiting mechanism, when the road obstacle is lifted, it can effectively contact and limit it, effectively avoiding random swaying under the influence of its own gravity during the moving and handling process. However, during the limiting operation of the auxiliary limiting mechanism on this road obstacle clearing device, since the limiting screw needs to rotate a large number of turns to achieve the limiting effect, the working efficiency of the road obstacle clearing device during use is reduced. Moreover, after the height of the auxiliary limiting mechanism is adjusted, since the wing nut is tightened for limiting, the wing nut is prone to loosen after being tightened, thus reducing the reliability of the auxiliary limiting mechanism during use.

[0043] The working principle of this embodiment: When in use, first move this road obstacle clearer to the obstacle clearing site through the universal wheels at the bottom of the U-shaped moving chassis 1. When the hook 206 is above the obstacle, hang the hook 206 on the obstacle, and then start the lifting motor 201 to drive the worm 202, the worm gear 204, and the reel 203 to rotate. The lifting rope 205 is wound by the rotating reel 203. At this time, the other end of the lifting rope 205 drives the hook 206 to move linearly upward, so as to lift the obstacle from the road surface.

[0044] After the obstacle is lifted, adjust the height of the height adjustment component 3. When adjusting the height of the height adjustment component 3 upward, only need to move the height adjustment component 3 upward, without pulling the T-shaped pull rod 403 forward. When it is necessary to adjust the height of the height adjustment component 3 downward, the T-shaped pull rod 403 can be pulled forward to drive the sliding block 402 and the trapezoidal insertion block 404 to move forward, so that the trapezoidal insertion block 404 is pulled out from the rectangular insertion hole 104, and then the height adjustment component 3 can be adjusted downward. When the height of the height adjustment component 3 is adjusted, drive the slider 602 to move towards the tail end direction of the spring guide rod 604 through the rotating rod 603, so that the slider 602 drives the insertion rod 605 to be pulled out from the limiting insertion hole 504, and then move the limiting plate 501 inward so that the rubber sheet 703 on the pressing surface of the pressing plate 701 is in close contact with the side surface of the obstacle, and then insert the insertion rod 605 into one of the corresponding limiting insertion holes 504 to quickly limit the limiting plate 501.

[0045] The two pressing mechanisms 7 and the two lifting support plates 301 can limit the obstacle, effectively avoiding the phenomenon that the obstacle swings violently during the lifting and moving process.
