Description

Leveling mechanism and ground leveling robot

Technical Field

The utility model relates to a construction equipment technical field particularly, relates to a leveling mechanism and ground leveling robot.

Background

With the increasing requirements on building quality, the quality of ground forming is particularly important, and the method is directly related to the realizable degree of a subsequent new process and method, such as a new floor tile thin-pasting process, a wood floor installation secondary-leveling-free technology and the like. The existing high-precision ground is continuously corrected mainly in a mode of manual polishing and retesting until the target requirement is met, the efficiency is low, the whole construction period is seriously influenced, the labor cost is high, and due to the fact that the technical levels of different workers are different, the effects of the high-precision ground are also different in level, and the difference is large.

The construction of high-precision concrete ground is divided into three important processes, namely ground leveling, floating, slurry lifting, surface collecting and polishing. The ground leveling process refers to elevation control and secondary vibration of the concrete ground after concrete pouring and paving, and a common constructor at the present stage comprises a wood trowel, a vibration leveling ruler, a vibration leveling beam and the like. The vibrating ruler is additionally provided with a vibrating motor on the basis of a wooden trowel, so that the compacting effect is further improved, the vibrating ruler also has the defects that the elevation is difficult to control and the construction efficiency is low, meanwhile, workers cannot work for a long time, and the physical strength of the workers is greatly tested by using the vibrating ruler. The vibrating beam then indicates to arrange the guide rail in concrete both sides, arranges the crossbeam between two guide rails to and at vibrating motor, drive the crossbeam simultaneously and move along the guide rail, thereby a concrete plane is gone out in the flattening, and the vibrating beam can guarantee better elevation face, and simultaneously, the effect of compaction is also better, but, the vibrating beam is established on the spot more troublesome, and is independent between every concrete plane, needs the later stage to do the seam, and efficiency is not high.

After the concrete is initially set, the concrete ground needs to be screeded and subjected to a grout lifting construction process, the screeding of the ground is an important process in the forming process of the concrete ground, and the implementation quality of the process directly influences the problems of whether the concrete is cracked in the later stage, the levelness of the ground and the like. The ground surface floating work mainly has three modes, the first mode is that a trowel is manually used for floating the ground surface, the efficiency is low, and the floating quality is not high; the second type is to use a hand-held trowelling machine, which needs to be supported by hands to operate, the trowelling plate is driven by a gasoline engine in a rotating way by walking through manual driving, and compared with manual trowelling, the hand-held trowelling machine is relatively labor-saving, but the efficiency is not high due to manual driving, the gasoline engine vibrates violently, the manual operation time cannot be too long, and the trowelling efficiency is general; the third is to use the driving trowelling machine, and the people can sit on the trowelling machine, operates the trowelling machine motion, compares in above-mentioned two kinds of modes, and this method is laborsaving, and efficiency is higher, but because its own characteristic problem, this equipment quality is great, when carrying out the ground floating work after the initial set, equipment often can leave great floating mark, and the effect of floating and receipts face is not good, and is better to the concrete ground polishing effect after the final set.

At present, automatic eveners are also available on the market to improve the construction effect of concrete floors. The existing automatic trowelling machine basically comprises a driving vehicle, a connecting support and a levelling mechanism, wherein the levelling mechanism is connected with the driving vehicle through the connecting support, and the connecting support can drive the levelling mechanism to move in the vertical direction. In the moving process of the leveling machine, if the driving vehicle encounters the problem of uneven ground, the leveling mechanism is subjected to the force of left and right inclination, and the leveling mechanism is often locked and cannot lift the scraper. In addition, because leveling mechanism's scraper blade is driven by two lift driving pieces and is gone up and down, often can also lead to the lift card of scraper blade to die because the motion of two lift driving pieces is asynchronous.
