Description

Technical Field

[0001] This utility model belongs to the field of construction equipment technology, and in particular relates to a concrete paver. Background Technology

[0002] In modern road construction, with the rapid growth of urban traffic flow, ultra-wide pavements with eight or more lanes in both directions have become the mainstream configuration for high-grade roads. Traditional concrete paving equipment generally adopts an integral vibratory roller structure, whose working width is limited by the material strength and structural stiffness characteristics. Engineering practice shows that when the roller length exceeds 8 meters, significant central deflection deformation will occur during continuous vibration compaction operations, directly affecting the pavement smoothness index, and in severe cases, even causing roller structure failure.

[0003] To address this issue, existing technologies typically employ a multi-segment roller splicing scheme. However, this scheme has two technical drawbacks: firstly, the axial gaps between adjacent roller segments can cause concrete material to accumulate and form longitudinal bulges; secondly, to eliminate joint marks, the construction team needs to assign 2-3 auxiliary workers to perform real-time leveling operations, which not only increases labor costs by 15% to 20%, but also reduces the plasticity of the initially set concrete due to the lag in manual operation.

[0032] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figure 1-4 As shown, a concrete paver includes a truss 1, a movable frame 2, a moving mechanism, and a paving mechanism. The movable frame 2 is symmetrically arranged at both ends of the truss 1, and the truss 1 can move up and down relative to the movable frame 2.

[0034] Specifically, the paving mechanism includes a spreading roller 31, a primary pressure roller 32, a finishing roller 33, a paving drive assembly, a scraper, a connecting rod 35, and a screed 36. The finishing roller 33 includes a connecting shaft 331, a pressure roller 332, a flange 333, a support plate 334, and bolts 335. At least two connecting shafts 331 are provided, with the outermost connecting shaft 331 rotatably connected to the truss 1. The number of pressure rollers 332 is the same as that of the connecting shafts 331, and they are fixed to the connecting shafts 331 respectively. The flange 333 is fixed to the end of the connecting shaft 331. The support plate 334 is fixed to the truss 1 and has a circular hole for the connecting shaft 331 to pass through. The bolts 335 pass through the flange 333. The structures of the spreading roller 31 and the primary pressure roller 32 are the same as those of the finishing roller 33, and will not be described again. The scraper is fixed to the truss 1, and the scraper is connected to the adjacent... The gaps between the pressure rollers 332 are correspondingly set, and the scraper bends towards the middle on both sides, forming a guide structure that can concentrate the concrete material and spread it evenly on both sides, reducing material accumulation at the edges; one end of the connecting rod 35 is fixed to the scraper; the trowel 36 is fixed to the end of the connecting rod 35 and is set horizontally, with the side of the trowel 36 near the scraper curving upwards in an arc. The arc design of the side of the trowel 36 near the scraper can lift excess concrete smoothly during troweling, reducing drag resistance and preventing material from getting stuck between the scraper and the trowel 36; the paving drive assembly uses a conventional motor, gears, and chains to drive the spreading roller 31, the initial pressure roller 32, and the fine pressure roller 33 to rotate; the paving mechanism consists of the spreading roller 31, the initial pressure roller 32, and the fine pressure roller 33, which are responsible for the distribution, initial compaction, and fine compaction of concrete, respectively. The precision pressure roller 33 is segmented through multiple independent connecting shafts 331 and pressure rollers 332, and is fixed to the flange 333 with the support plate 334. This design can disperse vibration pressure and prevent deflection in the middle of the long roller. The gap between the scraper and the pressure roller 332 is set accordingly, which can simultaneously scrape and level the concrete accumulation at the joint when the pressure roller 332 rotates. The trowel plate 36 at the end of the connecting rod 35 further trims the surface to ensure flatness. The synergistic effect of the scraper and the trowel plate 36 automatically processes the joint, reducing manual intervention, lowering construction costs and improving efficiency.

[0035] Specifically, the moving mechanism includes a hydraulic push rod 41, a guide rod 42, a fixed frame 43, moving wheels 44, a tilt sensor 45, and a moving drive assembly. The hydraulic push rod 41 is equipped with a PLC controller. The guide rod 42 is located on the other side of the moving frame 2 and can move up and down relative to the moving frame 2. The fixed frame 43 is fixed to the ends of the hydraulic push rod 41 and the guide rod 42. The moving wheels 44 are symmetrically arranged on the fixed frame 43. The tilt sensor 45 is a MEMS tilt sensor, which is installed on the moving frame 2 and is communicatively connected to the PLC controller of the hydraulic push rod 41. The hydraulic push rod 41 detects the tilt angle of the equipment in real time through the tilt sensor 45 and adjusts the extension and retraction of the push rod in conjunction with the controller, thus moving the mechanism. The moving frame 2 remains horizontal. The closed-loop control of the tilt sensor 45 and the hydraulic push rod 41 ensures the levelness of the paving process and avoids uneven road surface caused by equipment tilting. The moving drive assembly includes a moving shaft 441, a driven wheel 442, a driving wheel 443, a connecting belt 444, and a first drive component 445. The moving shaft 441 is fixed on the moving wheel 44 and rotatably connected to the fixed frame 43. The driven wheel 442 is a metal gear and is fixed on the moving shaft 441. The driving wheel 443 is a metal gear and is fixed on the output shaft of the first drive component 445. The connecting belt 444 is a metal chain and is sleeved on the driving wheel 443 and the driven wheel 442. The first drive component 445 is a conventional servo motor and is fixed on the fixed frame 43.

[0036] As a preferred embodiment, the moving mechanism further includes a screw 46, a limiting slider 47, a handle 48, and an adjusting plate 49. The screw 46 is rotatably connected to the moving frame 2; the limiting slider 47 is fixed to the truss 1, and the moving frame 2 is provided with a limiting groove that cooperates with the limiting slider 47; the handle 48 is fixed to the end of the screw 46; the adjusting plate 49 is fixed to the truss 1, and the adjusting plate 49 has a threaded hole that cooperates with the screw 46.

[0037] In other embodiments, the truss 1 is provided with a lighting mechanism, which includes a mounting plate 51, a lighting lamp 52, a fixing frame 53, a rotating shaft 54, a fixing sleeve 55, a mounting hole 56, an elastic element 57, a top rod 58, and a ball bearing 59.
