Description

Technical Field

[0001] The invention relates to the technical field of road surface leveling, in particular to a road surface leveling device for road construction. Background Art

[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. The asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by traffic and natural factors, making the road surface smooth, dust-free, impermeable and durable. Therefore, in the field of road construction, asphalt pavement is a high-grade pavement widely used.

[0003] In the prior art, a Chinese patent with publication number "CN114164731A" discloses an asphalt leveling device for road construction, comprising a connecting plate arranged at the rear of a vehicle body, a mounting plate being fixedly mounted on the outer wall of the connecting plate, two fixing seats being relatively arranged at the bottom of the left side of the mounting plate, a roller shaft being rotatably mounted between the two fixing seats, and a leveling roller being fixedly mounted on the outer wall of the roller shaft; when the leveling roller rolls, the second synchronous wheel can be driven to rotate through the roller shaft, the first synchronous wheel and the first synchronous belt, the second synchronous wheel can drive the driving wheel to rotate through the rotating shaft, the driving wheel can drive the driven wheel meshed with its outer wall to rotate, the driven wheel can drive the trowel plate to rotate through the vertical shaft, the trowel plate rotates on the asphalt pavement, so that the asphalt pavement can be leveled, and since the leveling of the trowel plate occurs before the leveling of the leveling roller, the leveling effect of the pavement can be further guaranteed.

[0004] The above patent can level the road surface to a certain extent, but in actual operation, the main pressure on the road surface comes from the leveling roller, and there is no other impact device to further compact and squeeze the road surface.

A plurality of guide windows 214 are provided around the fixing ring 212, which penetrate the fixing ring 212.

Can further compact and squeeze the road during the working process to ensure that the road surface is uniform and dense.

[0032] How it works

[0033] The road leveling device used in road construction is designed to achieve effective leveling and compaction of the road surface through a complex mechanical structure and electromagnetic control system, thereby improving the density and durability of the road.

[0034] Smoothing roller 1 and drive system

[0035] The leveling roller 1 is the core component of the device, which is designed to be able to roll on the road surface to perform the functions of leveling and compacting. The driving roller 101 is located in the middle of the leveling roller 1 and is connected to the driving system through the active bevel gear 201 to provide power.

[0036] Brush 205 system and control components 2:

[0037] The brush 205 system controls the direction and intensity of the current inside the device, affecting the direction of the magnetic force in the spiral coil 207. The control component 2 includes an active bevel gear 201 and a driven bevel gear 202, which transmit power through meshing to drive the operation of the leveling roller 1. The spiral coil 207 is fixed on the rotating cylinder 203, and forms a magnetic field through current control, cooperating with the pole 208 and the magnetic seat 216 to change the direction of the magnetic force. The design of the magnetic seat 216 and the lower pressure seat 217 allows the downward pressure potential energy to be increased through the synergistic effect of gravity and magnetism when the leveling roller 1 is working, thereby improving the density of the road surface.

[0038] The guide window 214 has a built-in guide roller 215, which is connected to the mounting platform 211 through the rotation of the fixed ring 212 to ensure the stability and accuracy of the device during operation. The device can perform leveling and compacting operations at the same time. Through the composite power system and mechanical design, it ensures that the road surface is evenly and fully squeezed, thereby improving the density of the road surface. Through the precise control of the brush 205 system and the spiral coil 207, the magnetic force direction inside the device can be adjusted to optimize the compaction effect and ensure the uniformity and durability of the road surface. The structural stability and durability of each component are taken into consideration in the design to ensure the reliability and durability of the device when working for a long time. The control system design of the device makes it easy to operate. The operator can accurately control the leveling and compacting effects by adjusting the current of the brush 205 system. The leveling device combines mechanical motion and electromagnetic control technology with the goal of improving road construction efficiency and construction quality. Through precise leveling and compaction operations, it ensures the uniformity and durability of the road surface, thereby improving the service life and safety of the road.
