[0004] "The device's support plate, connected load-bearing plate, and two foundation leveling components work together to level the foundation. It can also monitor the additional pressure applied to the foundation during leveling in real time and adjust the height of the scraper. As the device moves forward, the two pressing rollers roll on the foundation, allowing the scraper to level the raised parts.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a foundation leveling device for building construction, including a vehicle body 1, on which a leveling mechanism 2 is installed for foundation leveling, the leveling mechanism 2 including:

[0026] The main component 21 includes an upper ring seat 211 disposed below the vehicle body 1, a slewing bearing 212 mounted on the upper ring seat 211, and the upper ring of the slewing bearing 212 fixed to the bottom of the upper ring seat 211.

[0027] The execution component 22 includes a lower ring seat 221 fixed to the bottom of the lower ring of the slewing bearing 212. Shaft brackets 222 are fixed on both the left and right sides of the front end of the lower ring seat 221. A bracket 223 is pivotally connected to the lower end of the shaft bracket 222. A slider 224 is fixed to the inner end of the bracket 223. A guide rail 225 is slidably mounted on the slider 224. A blade 226 is fixed on the guide rail 225. A first hydraulic cylinder 227 is fixedly mounted on the inner end of the bracket 223, and the output end of the second hydraulic cylinder 228 is fixed to the blade 226.

[0028] In this implementation scheme, the smoothness and positioning accuracy of the lateral sliding of the blade 226 are achieved through the precise cooperation between the slider 224 and the guide rail 225, ensuring the straightness of the leveling operation; the first hydraulic cylinder 227 directly drives the blade 226 to move laterally; this allows the blade 226 to adjust its lateral position without changing the overall position of the equipment; and it enables the coverage width of a single operation to be adjustable, which can handle narrow areas and efficiently complete large-area leveling, significantly improving construction efficiency.

[0029] Specifically, the actuator 22 also includes a second hydraulic cylinder 228 pivotally connected to the upper end of the shaft bracket 222, and the output end of the second hydraulic cylinder 228 is pivotally connected to the bracket 223.

[0030] In this embodiment, the extension and retraction of the second hydraulic cylinder 228 can precisely control the pitch angle adjustment of the bracket 223 around the pivot point at the lower end of the shaft frame 222, thereby realizing the adjustment of the working tilt angle of the blade 226, enabling the blade 226 to quickly adapt to the construction requirements of different slopes and terrains.

[0031] Specifically, the main component 21 also includes a traction frame 213 fixed to the upper end of the upper ring seat 211, and the front end of the traction frame 213 is connected to the vehicle body 1 through a ball joint 214.

[0032] In this embodiment, the multi-degree-of-freedom connection characteristics of the ball joint 214 enable the leveling mechanism 2 to automatically adapt to the undulations of complex terrain, ensuring that the blade 226 always maintains the best contact angle with the working surface.

[0033] Specifically, the main component 21 also includes a mounting base 215 fixed inside the traction frame 213. A gear 216 is rotatably mounted inside the mounting base 215 and meshes with the gear ring of the slewing bearing 212 for transmission. A motor 217 is mounted on the top of the mounting base 215 and is used to drive the gear 216 to rotate.

[0034] In this embodiment, the output end of the motor 217 drives the gear 216 to cooperate with the slewing bearing 212 to drive the actuator 22 to rotate around the vertical axis, ultimately realizing the adjustment of the working angle of the blade 226. By changing the angle between the blade 226 and the traveling direction of the vehicle body 1, the soil or material pushing path can be optimized, significantly improving the leveling efficiency. When constructing on a slope, the slope gradient can be precisely controlled by adjusting the angle of the blade 226 to ensure construction accuracy. When encountering obstacles, the angle of the blade 226 can be quickly adjusted to avoid obstacles and maintain continuous operation.

[0035] Specifically, the leveling mechanism 2 also includes a mounting bracket 23 fixed on the vehicle body 1. Both ends of the mounting bracket 23 are equipped with third hydraulic cylinders 24, and the output end of the third hydraulic cylinders 24 is pivotally connected to the traction frame 213.

[0036] In this embodiment, the height and tilt angle of the entire leveling mechanism 2 are precisely adjusted by the cooperation of the third hydraulic cylinders 24 on both sides of the mounting frame 23, so that the equipment can adapt to construction conditions with different slopes and leveling requirements.

[0037] Specifically, the back of the scraper 226 is provided with several parallel reinforcing ribs, which extend longitudinally along the scraper 226 and are welded and fixed to the arc-shaped plate surface of the scraper 226.

[0038] In this embodiment, by setting longitudinally extending reinforcing ribs, the overall structural strength and deformation resistance of the blade 226 are significantly improved, enabling it to effectively resist bending stress when dealing with construction on hard foundations.

[0039] The working principle and usage process of this utility model are as follows: First, the precise cooperation between the slider 224 and the guide rail 225 achieves the stability and positioning accuracy of the lateral sliding of the blade 226, ensuring the straightness of the leveling operation; the first hydraulic cylinder 227 directly drives the blade 226 to move laterally; this allows the blade 226 to adjust its lateral position without changing the overall position of the equipment; and it enables adjustable coverage width for a single operation, which can handle narrow areas and efficiently complete large-area leveling, significantly improving construction efficiency.

[0040] Secondly, through the extension and retraction of the second hydraulic cylinder 228, the pitch angle of the bracket 223 around the pivot point at the lower end of the shaft frame 222 can be precisely controlled, thereby realizing the adjustment of the working tilt angle of the blade 226, so that the blade 226 can quickly adapt to the construction requirements of different slopes and terrains.

[0041] Then, the output end of the motor 217 drives the gear 216 to cooperate with the slewing bearing 212 to drive the actuator 22 to rotate around the vertical axis, ultimately realizing the adjustment of the working angle of the blade 226;

[0042] By changing the angle between the blade 226 and the vehicle body 1 in the direction of travel, the path of soil or material movement can be optimized, significantly improving leveling efficiency; when constructing on a slope, the slope gradient can be precisely controlled by adjusting the angle of the blade 226, ensuring construction accuracy; when encountering obstacles, the angle of the blade 226 can be quickly adjusted to avoid obstacles and maintain continuous operation.

[0043] Finally, through the cooperation of the third hydraulic cylinders 24 on both sides of the mounting frame 23, the height and tilt angle of the entire leveling mechanism 2 are precisely adjusted, enabling the equipment to adapt to construction conditions with different slopes and leveling requirements.
