摘要： A vibrating device includes a housing with a first and second cases that are connected to a mounting device and are connected to each other with a bridge tube. The mounting plate with the connected housing is removably connected to a blade of a cement smoothing device where the first and second cases are positioned on either side of a handle of the blade. The housing contains one or more motors to evenly impart a vibration to the blade. The housing also contains one or more sensor assemblies which are electrically connected to the one or more motors to selectively engage or disengage a circuit to power or not power the one or more motors. The one or more sensor assemblies are arranged to detect a tilt of the vibrating device to engage or disengage the power.

摘要： The present disclosure relates to the field of construction machinery, and discloses a troweling device and a troweling robot. The troweling device includes: a main body; a roller traveling mechanism mounted on the main body and can travel along a construction surface; and a vibrating slurry extracting mechanism mounted on the main body and located behind the roller traveling mechanism in a traveling direction of the troweling device. The vibrating slurry extracting mechanism can abut against the construction surface, and perform slurry extracting on slurry on the construction surface through vibration.

摘要： A self-propelled power trowel for finishing a concrete surface is equipped with reversible rotors to allow an operator to reverse the direction of rotation of rotor blades. The trowel includes a rigid frame adapted for operation over a concrete surface, a pair of rotor assemblies having rotor blades tiltably connected to the rigid frame for frictionally contacting the concrete surface and supporting the rigid frame thereabove, a prime mover mounted to the rigid frame and operatively coupled to drive the rotor blades of the rotor assemblies in opposite rotational directions. Synchronous or hydraulic motors are configured for causing, responsive to manual controls, reversal of the direction of rotation of the rotor blades.

摘要： A concrete float, float assembly, float adapter and interface, and float vibration apparatus and methods are described. A concrete float has improved surfaces, and structures for controlling flow of wet concrete. An interface such as may be included in a quick attach/release configuration may be integrated on a float, and/or may be added onto a float for quick attach/release of a pivot assembly. Adapters may ease attachment or release of an assembly, and may be an interengaging element, such as a sliding dovetail as an interengaging element, or an adapter may be used to place an assembly in tension to secure the assembly. A vibration assembly may be included and configured to have a low center of mass, can have a user display, an accelerometer, and/or other components. A pivot assembly may be included for easier use by an operator, and may include a user display, quick release mechanisms.

摘要： A poured, seamless polyurethane floor includes woodgrain markings and floorboard markings protected within a top clear coating, thereby to achieve a poured seamless floor with a “wood look.” The woodgrain markings are achieved by moving a heavy brush through the wear layer, during installation, prior to curing. The longitudinal floorboard markings may be achieved by moving a line marking apparatus over the upper layer, parallel with the woodgrain markings, after the wear layer has cured. The line marking apparatus assures distinct parallel floorboard lines on the wear layer, due to the use of permanent markers held in a downwardly biased, spring-loaded condition during movement of the apparatus over the floor. The installer then marks the transverse floorboard lines. A top coat seals and protects the woodgrain marking and the floorboard lines, thereby resulting in a seamless, poured polyurethane floor with a permanent wood look.

摘要： A screeding machine for screeding an uncured concrete surface includes a screed head assembly movable over the concrete surface via the screeding machine. A pair of elevation sensors disposed at opposite ends of the screed head assembly sense an elevation of the respective end of the screed head assembly. An angle sensor disposed at the screed head assembly senses a pitch angle and/or a roll angle of the screed head assembly. A gyroscope sensor disposed at the screed head assembly senses rotational velocity of the screed head assembly about a lateral axis and/or a longitudinal axis of the screed head assembly. A control uses gyroscope sensor data and angle sensor data to determine pitch angle and/or roll angle of the screed head assembly. The control controls the screed head assembly based on the signals from one or both of the elevation sensors and the determined pitch and/or roll angles.
