Description
Technical Field
The invention belongs to the technical field of constructional engineering equipment, and particularly relates to an out-of-control prevention hand-held ground troweling machine.
Background
The ground smoothing machine is also called a cement smoothing machine, is a concrete surface rough and fine smoothing machine tool, has smoother and flatter surface after machine construction compared with the surface constructed manually, can greatly improve the compactness and the wear resistance of the concrete surface, and can be widely used for slurry lifting, smoothing and smoothing of the concrete surface of pavements, high-standard factory buildings, warehouses, parking lots, squares, airports and frame-type buildings; the troweling machine is a preferred machine in concrete construction, the troweling machine can trowel 100-30 m2 per hour, and the working efficiency is improved by more than 10 times compared with manual operation in efficiency.
The ground troweling machine is generally divided into a walking type troweling machine and a driving type troweling machine, wherein the walking type troweling machine mainly structurally comprises a troweling rotor driven by a gasoline engine, and 2-4 trowels are mounted on the bottom surface of a cross in the middle of the rotor. The oblique direction of the spatula is consistent with the rotating direction of the rotor, and the gasoline engine drives the triangular belt to rotate the spatula rotor. When the device is operated, the operating handle is held firstly, the gasoline engine is started, then the oil door is filled, the gasoline engine is increased to rotate, the clutch is automatically engaged, and the trowel is driven to rotate to trowel the cement floor; under the idle state of the fuel engine, namely under the condition of not adding a fuel door, the clutch is automatically separated, and the spatula is stopped to be driven to rotate.
Although the hand-held troweling machine can greatly improve the construction efficiency, the polishing machines commonly used in the market generally have the following defects:
in the using process, the situation of out-of-control of the hands caused by misoperation exists, namely, in the working process of the equipment, if an operator leaves the handle of the handrail by both hands carelessly, the handrail rotates around the disc at a high speed, and the operator cannot approach the equipment to close the equipment under the condition of high-speed rotation of the handrail, so that the out-of-control phenomenon occurs; once out of control, the equipment must wait until the fuel in the fuel tank of the fuel engine is exhausted and stop naturally. The out-of-control troweling machine not only seriously affects the construction progress, but also seriously damages the construction ground; but also poses serious threats to the life safety of surrounding personnel. The main reason that the walking trowelling machine is easy to lose control is that the gasoline engine throttle switch is a fixed switch, and the gasoline engine runs at a certain rotating speed after the throttle is adjusted, so that an operator does not need to adjust the throttle during the use, but the phenomenon of losing control can happen once the trowelling machine is carelessly released.
