Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to an embossing device for concrete pavement. Background Technology

[0002] Currently, when texturing the concrete pavement after pouring, brush texturing machines or stainless steel texturing machines are usually used for surface texture treatment. This texturing method has technical pain points such as poor work continuity and strict requirements for pressure control. Specifically, the construction work must be completed continuously in one go without interruption; the operator must accurately control the pressure of the texturing machine to ensure uniform texture depth; and frequent movement of formwork and repeated lifting of equipment lead to high labor intensity and low construction efficiency.

[0003] Existing technologies cannot guarantee the stability of the straightness of the texture and the depth of the structure, which directly affects the anti-skid performance and appearance quality of the road surface, and there are no effective means to repair quality defects.

[0032] Reference Appendix Figure 1-3 This embodiment provides a textured surface device for concrete pavement, comprising: a first guide rail 1, a second guide rail 2, a limiting mechanism 3, and a textured surface mechanism 4. The first guide rail 1 extends along the length of the road, and the second guide rail 2 extends along the width of the road. For a straight road, the extension directions of the first guide rail 1 and the second guide rail 2 are perpendicular. The first guide rail 1 is disposed on both sides of the road, and the second guide rail 2 is movably disposed on the first guide rail 1, with at least a portion of the second guide rail 2 located above the road surface. The limiting mechanism 3 connects the first guide rail 1 and the second guide rail 2 and is used to limit the movement of the second guide rail 2. The textured surface mechanism 4 is movably disposed on the second guide rail 2, and when it moves along the second guide rail 2, it can texture the road surface, with the textured surface extending along the width of the road.

[0033] The first guide rail 1 and the second guide rail 2 can both be made of C-shaped steel commonly used on construction sites. The first guide rail 1 is located on both sides of the road, with its opening facing away from the road. Support ribs 5 are installed on the sides of the first guide rail 1 to hold it firmly against the road side. The second guide rail 2 is located above the road surface, with its opening vertically upwards to facilitate connection to the embossing mechanism 4. (See attached reference.) Figure 2 The support rib group 5 includes a first longitudinal rib 51, a second longitudinal rib 52, a transverse brace 53, and a diagonal brace 54. The first longitudinal rib 51 is located inside the first guide rail 1, and its top and bottom ends abut against the inner wall of the first guide rail 1. The second longitudinal rib 52 is located outside the first guide rail 1 and is anchored in the ground foundation. The transverse brace 53 connects the first longitudinal rib 51 and the second longitudinal rib 52 laterally. The top end of the diagonal brace 54 is connected to the first longitudinal rib 51, and the bottom end of the diagonal brace 54 is connected to the connection between the second longitudinal rib 52 and the transverse brace 53. The first longitudinal rib 51, the transverse brace 53, and the diagonal brace 54 form a triangular stable structure, and the first guide rail 1 is stably supported by the second longitudinal rib 52 anchored in the ground foundation.

[0034] Reference Appendix Figure 2, the limiting mechanism 3 for limiting the second guide rail 2 includes: a first carriage 31, a second carriage 32, a connecting bolt 33, a first self-locking wheel 34 and a second self-locking wheel 35. The first carriage 31 and the second carriage 32 have the same configuration and face each other. They are respectively located on the upper and lower sides of the top wing plate of the first guide rail 1 (taking the example that the first guide rail 1 selects a C-shaped steel and the opening faces away from the road). The second guide rail 2 is located above the first carriage 31. The first carriage 31 and the second carriage 32 respectively include a connecting plate 36 extending in the same direction as the first guide rail 1, and "J"-shaped seats 37 located at both long ends of the connecting plate 36. The first self-locking wheel 34 is located on the first carriage 31 and is configured at the end of the "J"-shaped seat 37 close to the web of the first guide rail 1. The second self-locking wheel 35 is located on the second carriage 32 and is configured at the end of the "J"-shaped seat 37 close to the web of the first guide rail 1. The first self-locking wheel 34 and the second self-locking wheel 35 respectively abut against the upper and lower surfaces of the top wing plate of the first guide rail 1. A bolted plate 38 is configured at the end of the "J"-shaped seat 37 far from the web of the first guide rail 1. After both ends of the connecting bolt 33 respectively penetrate through the bolted plates 38 in the first carriage 31 and the second carriage 32, the two can be stably connected.

[0035] During implementation, first place the second guide rail 2 on the top of the connecting plate 36 of the first carriage 31 and bolt it tightly; then adjust the directions of the second guide rail 2, the first carriage 31 and the second carriage 32 to make the second guide rail 2 extend in the same direction along the road width direction, and use the connecting bolt 33 to connect the first carriage 31 and the second carriage 32 (slightly loose); then move the second guide rail 2 along the first guide rail 1 and move it above the road surface area to be embossed. Again, finely adjust and复核 the second guide rail 2 to extend along the road width direction, lock the first self-locking wheel 34 and the second self-locking wheel 35, and lock the connecting bolt 33 to ensure the position and direction stability of the second guide rail 2; finally, place the embossing mechanism 4 on the second guide rail 2 and make the embossing mechanism 4 move along the second guide rail 2 to emboss the road surface.

[0036] Reference appendix Figure 3 , the embossing mechanism 4 includes a roller frame 41, a first driving handle 42, an embossing roller 43 and an adjusting component 45. The first driving handle 42 is configured on the roller frame 41 so that when a person holds and pulls it, it can带动 the roller frame 41 to move along the second guide rail 2; the surface of the embossing roller 43 is provided with embossing ridges, and the embossing roller 43 is connected to the roller frame 41 through the adjusting component 45, and the adjusting component 45 can change the embossing depth by adjusting the height of the embossing roller 43.

[0037] Note: There is an unclear "复核" in the Chinese text which is tentatively translated as "复核" here. It might need to be further clarified in the original context for a more accurate translation.In this embodiment, the roller frame 41 includes a first C-shaped frame 411 and a second C-shaped frame 413, both with their openings facing the second guide rail 2. The second C-shaped frame 413 is located inside the first C-shaped frame 411 and is connected to the first C-shaped frame 411 by an adjusting component 45. The adjusting component 45 can change the height of the embossing roller 43 by adjusting the distance between the sealed end (i.e., the top end) of the first C-shaped frame 411 and the sealed end (i.e., the top end) of the second C-shaped frame 413. The two axial ends of the embossing roller 43 are respectively rotatably connected to the open end (i.e., the side end) of the second C-shaped frame 413. The bottom end of the first C-shaped frame 411 is provided with a movable wheel 44, which is movably disposed in the second guide rail 2.

[0038] During implementation, the height of the embossing roller 43 is first changed using the adjustment component 45 so that the embossing depth meets the construction requirements; then, a person holds and pulls the first drive handle 42 to move the roller frame 41 and the embossing roller 43 along the second guide rail 2 to achieve embossing.

[0039] In this embodiment, the adjustment assembly 45 includes a bidirectional lead screw 451, a second drive handle 452, a transmission block 453, and an adjusting rod 454. The bidirectional lead screw 451 is rotatably connected to the side plate of the first C-shaped frame 411. The second drive handle 452 is located at the end of the bidirectional lead screw 451 and is used to drive the bidirectional lead screw 451 to rotate. The transmission block 453 and the adjusting rod 454 are respectively provided in two sets, and the two sets of transmission blocks 453 are respectively threaded to the bidirectional lead screw 451 with opposite threads. The two ends of the adjusting rod 454 are respectively rotatably connected to the sealing end of the second C-shaped frame 413 and the transmission block 453. When a person holds and rotates the second drive handle 452, the two sets of transmission blocks 453 are subjected to force and move towards or away from each other, thereby driving the adjusting rod 454 to rotate. When the adjusting rod 454 rotates, the vertical height difference between its top and bottom ends will change, thereby causing the height of the second C-shaped frame 413 and the embossing roller 43 to change.

[0040] In addition to the above, the side plate of the first C-shaped frame 411 is also provided with a vertical sliding hole 412, and a sliding limit member 46 is provided in the vertical sliding hole 412. The other end of the sliding limit member 46 is connected to the second C-shaped frame 413. The vertical sliding hole 412 restricts the movement path of the sliding limit member 46, that is, the sliding limit member 46 can only slide vertically and cannot move horizontally. Therefore, during the rotation of the second drive handle 452, the transmission block 453 can only move axially along the double-acting screw 451 due to the indirect restriction of the sliding limit member 46 and the vertical sliding hole 412, and cannot rotate around the double-acting screw 451. This ensures that the process of adjusting the height of the embossing roller 43 is more efficient, and avoids the problem of the second C-shaped frame 413 tilting or shifting due to the squeezing friction between the embossing roller 43 and the road surface during the process of pulling the embossing mechanism 4 along the second guide rail 2.

[0041] The shape of the sliding limit member 46 can be configured according to actual needs. For example, it can be an inclined rod, and an anti-detachment block 461 is provided at the end of the inclined rod that extends out of the vertical sliding hole 412. The width of the anti-detachment block 461 is greater than the width of the vertical sliding hole 412.

[0042] When using this embossing device for road surface embossing, the following steps are included:

[0043] (1) Lay the first guide rail 1 along the road length direction, and use the support rib group 5 to support the two first guide rails 1 on both sides of the road.

[0044] (2) Connect the limiting mechanism 3 to the top wing plate of the first guide rail 1, and lay the second guide rail 2 along the road width direction and connect it to the limiting mechanism 3.

[0045] (3) Move the limiting mechanism 3 along the first guide rail 1, thereby moving the second guide rail 2 above the area to be embossed, and locking the first self-locking wheel 34, the second self-locking wheel 35 and the connecting bolt 33;

[0046] (4) Place the embossing mechanism 4 in the second guide rail 2 and rotate the second drive handle 452 to adjust the height of the embossing roller 43, thereby changing its embossing depth.

[0047] (5) Pull the first drive handle 42 to move the embossing mechanism 4 along the second guide rail 2, thereby embossing the road surface;

[0048] (6) Loosen the first self-locking wheel 34, the second self-locking wheel 35 and the connecting bolt 33, and repeat steps (3) to (5) to gradually carry out the complete embossing construction on the road surface.

[0049] It is worth noting that after each set of embossing operations is completed, the position of the embossing mechanism 4 on the second guide rail 2 can be used as the starting point for the next set of embossing operations. That is, in the previous set of embossing operations, the embossing mechanism 4 is pulled and moves from the first end to the second end of the second guide rail 2. When the second guide rail 2 and the embossing mechanism 4 are moved synchronously to the area above the next embossing area, the embossing mechanism 4 can be pushed back from the second end to the first end of the second guide rail 2 to complete the current set of embossing operations.

[0050] Compared with the prior art, the beneficial effects of this utility model include at least the following:

[0051] (1) Through the coordinated design of dual-track orientation (first guide rail 1, second guide rail 2) and height-adjustable embossing roller 43, the quality problems such as poor straightness of texture and uneven texture depth in traditional construction process are solved, and the anti-skid performance and surface quality of the road surface are significantly improved.

[0052] (2) The limit components ensure the stability of continuous operation over ultra-long distances, greatly reducing the frequency of process interruptions. Combined with the manual adjustment mechanism, it optimizes both ease of operation and labor efficiency.

[0053] (3) The modular guide rails and replaceable embossing devices not only simplify the equipment transfer process, but also reduce human error through standardized construction processes, forming an innovative concrete pavement surface treatment device that combines construction accuracy, work efficiency and economy.

[0054] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
