Description

Technical Field

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

[0002] At present, for sections that are convenient for rollers to roll, rollers are mostly used; however, in actual engineering, there are some sections with large slopes, narrow roads, sharp bends and other construction difficulties, where rollers cannot operate. Such roads or bridge decks usually require manual hand-held compactors to compact and pave the road surface or bridge deck to make it stronger.

[0003] In the related art, reference can be made to the Chinese patent with the announcement number CN215715212U, which specifically discloses a tamping device for bridge and road construction. When the tamping device for bridge and road construction is used, when the device needs to be moved, the clamping plate is controlled by the hydraulic cylinder to clamp and fix the tamping hammer to avoid shaking and safety hazards during the movement. When the tamping hammer contacts the buffer block during the rising process, the impact force of the tamping hammer is reduced through the mutual matching between the buffer spring and the buffer block, so as to avoid the top plate from being damaged, which is conducive to improving the service life of the top plate.

[0004] The applicant found that there were deficiencies in the use of the above-mentioned compaction device for bridge and road construction: although the rammer was clamped and fixed by the hydraulic cylinder to avoid shaking and safety hazards during movement, when the rammer was used, it was necessary to control the separation of the clamp and the rammer by the hydraulic cylinder. At this time, the rammer was connected to a steel wire rope, so the rammer would shake to a certain extent, and the rammer would move upward under the pull of the steel wire rope, so the rammer would also shake. If there was strong wind or external force, the rammer would also shake. Since the rammer needed to pass through the slot to work when it fell, the above-mentioned problems would easily affect the stable fall of the rammer from the slot.

[0005] In view of this, the present technical solution proposes a laying mechanism for bridge and road construction, so as to better solve the above-mentioned problems. Utility Model Content

[0031] The auxiliary support plate 7 is driven by the hydraulic cylinder 6 to move its position. At this time, with the cooperation of the limit rod 8, the stability of the movement of the auxiliary support plate 7 is increased. At the same time, the auxiliary support plate 7 is supported on the ground to protect the universal wheel 5 and increase the service life of the universal wheel 5.
