Description

Technical Field

[0001] The utility model relates to the technical field of foundation leveling equipment, in particular to a foundation leveling mechanism. Background Art

[0002] Land leveling refers to the transformation of the land surface conditions through demolition and earthwork, the removal of buildings, structures and obvious height differences in different locations of the land, so that the requirements of subsequent construction are met. Land leveling is mostly a necessary condition for ground construction projects and land consolidation. For example, before real estate development, the target land must be developed at the first level so that it meets the construction standards of "three connections and one leveling" or "seven connections and one leveling". The "three connections" refer to "electricity, water, and roads", and the other "one leveling" means that the land has been leveled and has met the construction conditions for subsequent real estate development and the conditions for occupancy after the project is completed.

[0003] For example, a Chinese patent (CN220166874U) discloses a foundation leveling mechanism, including a working frame and an adjusting structure, wherein a cylinder is installed on the upper part of the working frame, the output end of the cylinder is directed downward, a connecting shaft is fixedly connected to the output end of the cylinder, a leveling plate is fixedly connected to the bottom of the connecting shaft, and the adjusting structures are all installed on the upper part of the working frame; the adjusting structure includes a supporting frame, the supporting frame is fixedly connected to the working frame, a driving motor is fixedly connected to the upper part of the supporting frame, the output end of the driving motor is directed downward, a gear is fixedly connected to the output end of the driving motor, and a rack is meshed and connected to the right side of the gear; pads are fixedly connected to the top and bottom of the fixed block. The foundation leveling mechanism has an adjusting structure installed on the working frame, and the adjusting structure can adjust the leveling position of the leveling plate relative to the ground, thereby saving workers' labor and improving the leveling efficiency of the leveling mechanism.

[0004] The above scheme also has the following technical deficiencies: the above scheme is not convenient for flattening protruding soil blocks. Since protruding soil blocks will be encountered during the land leveling process, if the leveling plate is simply used to impact and level them, it will not have a good leveling effect. It takes many impacts to make the protruding position as flat as the adjacent position. Based on this, a foundation leveling mechanism is proposed. Utility Model Content

[0008] Furthermore, the leveling mechanism includes a hydraulic cylinder fixed to the bottom end of the rotating plate, a connecting rod is fixed to the telescopic end of the hydraulic cylinder, a push plate is fixed to the bottom end of the connecting rod, a first sleeve is sleeved on the outer surface of the connecting rod, a spring is placed in the first sleeve, a leveling plate is fixed to the bottom end of the first sleeve, two second sleeves are fixed to the top end of the leveling plate, two limit rods are slidably connected inside the second sleeve, and two limit blocks are fixed to the bottom end of the limit rod.

[0009] Furthermore, a bearing seat is fixed to the top of the working frame, and the rotating column rotates in the bearing seat.

[0010] Furthermore, an annular slide groove is provided at the bottom end of the working frame, and the sliding block slides in the annular slide groove.

[0011] Furthermore, the top end of the limiting rod is fixed to the bottom side of the rotating plate, and the plurality of groups of flattening knives are fixed to the four sides of the flattening plate respectively.

[0012] Furthermore, the top end of the spring abuts against the bottom side of the push plate, and the bottom end of the spring abuts against the bottom side of the inner wall of the first sleeve.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The foundation leveling mechanism is provided with a leveling mechanism on a working frame so that the device can level raised soil blocks, thereby eliminating the need to simply use a leveling plate to level raised soil blocks, thereby improving the efficiency of foundation leveling.
