Commonly used paving materials include precast blocks, ceramic bricks, terracotta bricks and permeable bricks, etc. The specifications and applicable scope are selected according to specific usage requirements.

[0003] Based on the above, the inventors have discovered the following shortcomings in existing pedestrian pavement construction devices:

[0004] 1. When the device is dragged to press down on the permeable bricks, it is easy to come into contact with the curb stone, causing the device to get stuck. It is inconvenient to install contact measures at both ends of the device to prevent the device from getting stuck when dragging.

[0005] 2. The length of the device spanning the road surface is fixed and cannot be adjusted according to the width of the permeable brick paving. It is inconvenient to set the compaction roller as a sheet structure to increase or decrease it according to the width of the road surface. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a pedestrian pavement construction device. This addresses the issues of existing devices easily coming into contact with curb stones and getting stuck when dragging permeable bricks for compaction, making it inconvenient to install contact measures at both ends of the device to prevent jamming during dragging; the fixed length of the device spanning the road surface, making it impossible to adjust according to the width of the permeable bricks, and the inconvenience of setting the compaction roller as a sheet structure to increase or decrease it according to the road width.

[0007] The purpose and effectiveness of this utility model pedestrian pavement construction device are achieved through the following specific technical means:

[0008] A pedestrian pavement construction device includes a device body; the device body is provided with a compaction roller rod in the left-right direction, a limiting ring plate is provided on the outer circumference of the compaction roller rod, a through hole is provided below the limiting ring plate of the compaction roller rod in the left-right direction, a fixing post is provided on both the left and right end faces of the compaction roller rod, and a frustum contact plate in the left-right direction is sleeved on both ends of the compaction roller rod, a U-shaped groove in the front-back direction and the left-right direction is provided in the interior of the frustum contact plate, an arc-shaped strip hole in the top-bottom direction and the left-right direction is provided in the front of the inner end of the U-shaped groove of the frustum contact plate, and through holes in the top and bottom of the inner end of the U-shaped groove of the frustum contact plate are provided in the left-right direction.

[0009] Furthermore, the outer circumference of the locking nut cylinder is provided with a regular hexagonal structure, and both the left and right end faces of the locking nut cylinder are provided with a frosted surface.

[0010] Furthermore, the outer circumference of both ends of the limiting anti-detachment rod is threaded with locking nut sleeves in the left and right directions, and the inner circumference of the locking nut sleeves is threaded.

[0011] Furthermore, a left-right directional limiting anti-detachment rod is inserted into the through hole of the compaction roller rod. The outer circumference of the limiting anti-detachment rod is threaded, and both the left and right end faces of the limiting anti-detachment rod are provided with regular hexagonal grooves.

[0012] Furthermore, the inner end of the U-shaped groove of the circular compaction plate is provided with an arc-shaped strip hole that runs through the vertical direction in both the left and right directions, and the inner end of the U-shaped groove of the circular compaction plate is provided with through holes that run through the vertical direction in both the top and bottom.

Fixing posts are provided on both the left and right end faces of the compaction roller rod 2 to facilitate the installation of the roller support rod 4 through bearings. Both ends of the compaction roller rod 2 are fitted with left-right oriented frustum contact plates 3 to facilitate contact with the curb stone. The frustum contact plates 3 have front and rear oriented... The U-shaped groove extending to the left and right facilitates the entry and exit of the compaction roller rod 2. The inner end of the U-shaped groove of the frustum contact plate 3 has an arc-shaped strip hole extending vertically and horizontally, which is convenient for hand insertion and gripping. The inner end of the U-shaped groove of the frustum contact plate 3 has through holes extending horizontally at both the top and bottom, which is convenient for the limit anti-detachment rod 6 to pass through. The left and right roller bearing rods 4 are installed between the fixed columns of the compaction roller rod 2 through bearings, which is convenient for the compaction roller rod 2 to rotate through the bearings. The roller bearing rod 4 has a U-shaped rod structure, which is convenient for rope installation. Both ends of the roller bearing rod 4 are provided with left and right through fixed cylinders, which is convenient for the compaction roller rod 2 to be installed through the bearings.

[0029] The compaction roller rod 2 is surrounded by circular compaction plates 5 arranged horizontally to facilitate compaction of the permeable bricks. The circular compaction plates 5 have U-shaped grooves running horizontally and vertically to allow the compaction roller rod 2 to pass through. The inner end of the U-shaped groove of the circular compaction plate 5 has an arc-shaped hole running horizontally and vertically to allow for hand gripping. The inner end of the U-shaped groove of the circular compaction plate 5 has horizontal through-holes at both the top and bottom to allow the anti-detachment rod 6 to pass through. The anti-detachment rod 6 is inserted into the through-hole of the compaction roller rod 2 to prevent detachment between the circular compaction plate 5 and the frustum-shaped contact plate 3. The outer circumference of the anti-detachment rod 6 is circular... The locking nut cylinder 7 is threaded around its circumference, facilitating its installation via threaded connection. The left and right ends of the limiting anti-disengagement rod 6 are each provided with a regular hexagonal groove, allowing tools to be inserted for rotation and stopping.

Both the left and right ends of the locking nut cylinder 7 are provided with a frosted surface, increasing friction with the frustum contact plate 3 and preventing the locking nut cylinder 7 from loosening during rotation.

[0030] The specific usage and function of this embodiment are as follows:

[0031] In this utility model, when... Figure 1 As shown, when using the device body 1, it is placed on top of the permeable bricks paved on the pedestrian walkway, as shown in the diagram. Figure 4 As shown, the frustum contact plate 3 is positioned inside the curbstone, and its conical surface contacts the curbstone, thus preventing the right-angled structure from easily getting stuck. A rope is tied to the middle of the roller support rod 4, and the device body 1 is moved along the pedestrian walkway by the rope. The weight of the components on the compaction roller rod 2 compacts the permeable bricks. Figure 1 As shown, when disassembling the circular compaction plate 5, insert a tool into the regular hexagonal groove of the limiting anti-detachment rod 6 to prevent rotation of the limiting anti-detachment rod 6. Then, rotate the locking nut sleeve 7 with the tool to engage with the threaded engagement of the limiting anti-detachment rod 6, causing the locking nut sleeve 7 to move to the left and disengage from the outer circumference of the limiting anti-detachment rod 6, as shown. Figure 5 As shown, then the frustum contact plate 3 is moved to the left, causing the frustum contact plate 3 to disengage from the outer circumference of the limit anti-disengagement rod 6, as shown in the figure. Figure 6As shown, insert your hand into the arc-shaped slot of the frustum contact plate 3 and hold it. Move the frustum contact plate 3 forward to disengage it from the compaction roller rod 2, thereby disassembling the frustum contact plate 3. Then, move the circular compaction plate 5 to the left to disengage it from the outer circumference of the limiting anti-detachment rod 6. Insert your hand into the arc-shaped slot of the circular compaction plate 5 and hold it. Move the circular compaction plate 5 to disengage it from the compaction roller rod 2, thereby disassembling the circular compaction plate 5. This method of disassembling and adding / removing the circular compaction plate 5 makes it convenient to adjust according to the width of the permeable brick paving.

[0032] Example 2:

[0033] The difference from Embodiment 1 is that the regular hexagonal groove of the limiting anti-detachment rod 6 can also be set as a regular heptagonal groove, so that the limiting anti-detachment rod 6 can only be rotated by a special tool that cooperates with the regular heptagonal groove, thus preventing non-workers from rotating and disassembling the limiting anti-detachment rod 6.

[0034] Example 3:

[0035] The difference from Embodiment 1 is that the regular hexagonal structure of the locking nut cylinder 7 can also be set as a regular heptagonal structure, which makes the locking nut cylinder 7 require a special tool that cooperates with the regular heptagonal structure to rotate, thus preventing non-workers from rotating and disassembling the locking nut cylinder 7.
