A ground leveling device

Abstract

The invention discloses a ground leveling device comprising a rack and a hydraulic telescopic rod connected to the rack. A connection frame horizontally arranged is fixedly connected with the tail endof the hydraulic telescopic rod, and hydraulic cylinders are separately fixedly connected with two ends of the connection frame; piston rods of the hydraulic cylinders are vertically arranged and a leveling plate is fixed at the ends of the piston rods, and support frames are vertically slidably connected with the leveling plate; the support frames are slidably connected with a scraping plate inthe width direction of the leveling plate, the scraping plate is arranged in the length direction of the leveling plate, and when the bottom surface of the leveling plate is adhered to a concrete surface, the bottom surface of the scraping plate is higher than the bottom surface of the leveling plate; a first transmission part is fixed on the connection frame, the leveling plate is provided with asecond transmission part, and the second transmission part is matched with the first transmission part to drive the supporting frames to move downwards relative to the leveling plate when the leveling plate moves upwards to break away from the concrete surface; and the scraping plate is provided with a first driving mechanism in a fitted mode, and the first driving mechanism drives the scraping plate to slide in the width direction of the leveling plate when the scraping plate moves downwards until the upper end surface of the scraping plate is flush with the bottom surface of the leveling plate. The ground leveling device can quickly and promptly remove concrete which adheres to the bottom of the leveling plate.

Description

technical field

[0001] The invention relates to the field of construction machinery, more specifically, it relates to a ground leveling device. Background technique

[0002] In the summary of the building construction process, after the grouting construction of the building is completed, after the formwork is subsequently removed, only a rough cement floor can be formed. Since the cement floor area is quite large, it takes a lot of labor and time to complete the cement slurry layer leveling construction. Currently, cement The ground leveling construction mainly uses a leveler to level the semi-dry cement slurry on the cement floor manually.

[0003] The Chinese patent with the patent notification number CN103758351A discloses a concrete laser leveling machine, which includes a frame, a laser system and a computer control system. The two ends of the connecting frame are respectively connected with hydraulic cylinders, the piston rods of the hydraulic cylinders are hinged wit...
