Description

Technical Field

[0001] This utility model relates to the field of road stone loading technology, specifically a road stone alignment retaining device. Background Technology

[0002] Road paving stones are strips of stone or concrete products laid along the edges of roads. They are mainly used to demarcate the boundaries between roads and shoulders, sidewalks, green belts, etc., to prevent vehicles from accidentally entering sidewalks or green belts and to avoid damage to the road surface and ancillary facilities.

[0003] During the paving of paving stones, it is often necessary to place them upright in the pre-embedded trenches dug along the roadside, and then fill them with concrete to keep them upright and stable. However, without an auxiliary stabilizing structure, the paving stones may shift to varying degrees during the concrete filling process. In this case, the deviation in alignment needs to be repaired later, which leads to time and resource consumption. Utility Model Content

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: including a bottom fixing plate 1 and an upper positioning frame 4. A crossbeam 2 is fixed at the middle position of the upper end of the bottom fixing plate 1, and a vertical plate 3 is fixed at the upper end of the crossbeam 2. The front side of the vertical plate 3 is slidably connected to the upper positioning frame 4, and a one-way sliding component is provided between the two. The upper positioning frame 4 has an L-shaped structure, and a positioning plate 5 is slidably connected to the bottom. A driving component is provided on the inner wall of the upper positioning frame 4. Positioning holes 11 are opened at the four corners of the bottom fixing plate 1. A T-shaped groove is opened on the vertical plate 3, and a T-shaped block that matches the T-shaped groove is opened on the upper positioning frame 4.

[0018] The drive assembly includes a horizontal groove 41 and a knob 44. The horizontal groove 41 is formed on the inner wall of the upper positioning frame 4. An adjusting block 42 is slidably connected in the horizontal groove 41. The bottom of the adjusting block 42 is fixedly connected to the positioning plate 5. The knob 44 is rotatably connected to the end of the upper positioning frame 4. A threaded rod 43 is rotatably connected in the horizontal groove 41. The end of the threaded rod 43 passes through the adjusting block 42 and is threadedly connected to the adjusting block 42. The end of the threaded rod 43 is fixed to the knob 44.

[0019] The one-way sliding assembly includes a right-angled toothed block 32 and a right-angled toothed groove 45. The right-angled toothed block 32 is installed on the side of the upright plate 3 near the upper positioning frame 4 and is symmetrically distributed. The right-angled toothed groove 45 is opened on the side wall of the upper positioning frame 4 and is aligned with the right-angled toothed groove 45. The end of the right-angled toothed block 32 is inserted into the right-angled toothed groove 45. A telescopic groove 31 is opened in the upright plate 3 at a position corresponding to the right-angled toothed block 32. The end of the right-angled toothed block 32 is located in the telescopic groove 31 and a push-out spring 33 is fixed between it and the side wall of the telescopic groove 31. A pull rod 34 is fixed at one end of the right-angled toothed block 32 located in the telescopic groove 31. The end of the pull rod 34 extends out of the upright plate 3. A connecting plate 35 is fixed between the pull rods 34, and a through hole 21 is opened on the crossbeam 2 at a position corresponding to the connecting plate 35.

[0020] Working principle: First, insert the bottom of the paving stone into the pre-reserved roadside groove. Then, use bolts to fix the bottom fixing plate 1 at the designated position on the ground by passing it through the positioning hole 11, so that the upper end of the paving stone is between the upper positioning frame 4 and the positioning plate 5. Next, adjust the height of the upper positioning frame 4 so that the upper end of the paving stone abuts against the bottom of the upper positioning frame 4. Then, by sliding the positioning plate 5, the side wall of the positioning plate 5 abuts against the side wall of the paving stone. At this time, the upper end of the paving stone can be kept stable, avoiding the risk of the paving stone shifting during the concrete grouting process. In specific operation, the downward pressure of the upper positioning hole 11 will squeeze the right-angle toothed block. When the upper positioning frame 4 enters the telescopic groove 31 and rises, it is blocked by the bottom plane of the right-angle toothed block 32. Therefore, when there is no external force, the upper positioning frame 4 can only slide downward on the vertical plate 3. So, it is only necessary to press down the upper positioning frame 4 so that it abuts against the upper end of the road stone. At the same time, when it is necessary to slide the upper positioning frame 4 upward, it is only necessary to pull the connecting plate 35 and the pull rod 34 to drive the right-angle toothed block 32 to slide into the telescopic groove 31. Then, by rotating the knob 44, the threaded rod 43 can be rotated, so that the adjusting block 42 slides in the horizontal groove 41, and finally drives the adjusting block 42 to slide.
