Description
Technical Field
[0001] The utility model relates to the technical field of trowel machine operation safety, in particular to a trowel machine with a hands-off protection function. Background Art
[0002] Trowel machines can be divided into two categories according to the type of working device: disc trowel machines and blade trowel machines. Blade trowel machines have two types: single trowel head and double trowel heads. According to the power, they can be divided into electric and internal combustion types. Disc trowel machines are mainly used for concrete slurry and leveling, while blade trowel machines are mainly used for troweling in the subsequent construction of concrete. They are a kind of concrete floor construction machinery with good construction quality and high efficiency.
[0003] At present, the gasoline floor trowels used in the market are shut down by pulling back the throttle switch, which reduces the speed of the gasoline engine, opens the clutch wheel, loosens the belt, and stops the trowel. The disadvantage is that sometimes the gasoline throttle adjustment fails, and the gasoline engine speed cannot be reduced by loosening the throttle, or the clutch wheel cannot be separated when starting the gasoline engine, causing the trowel handle to slip out of the hand and rotate with the trowel, and the automatic shutdown switch fails again, and the trowel cannot be shut down, causing the handle to rotate with the trowel and injure people, which poses certain safety hazards.
[0004] For this purpose, we propose a trowel machine with a hands-off protection function. Utility Model Content
[0005] The utility model aims to provide a trowel machine with a hands-off protection function to solve the problems raised in the above-mentioned background technology.

A switch control component is installed on the surface of the frame, and the switch control component is used to stop the overall operation of multiple control devices, and the switch control component can make the overall device safer during operation.
[0007] Preferably, the position of the swing arm body and the position of the safety anchor body correspond to each other when in a normal state.
[0008] Preferably, a gasoline engine body is installed in the middle of the frame, and a leveling device body is installed on the bottom surface of the gasoline engine body.
[0009] Preferably, a large handle is installed on the right side of the trowel device body, a small handle is installed on the right end of the large handle, and the angle between the small handle and the large handle can be adjusted.
[0010] Preferably, the switch control assembly comprises a remote control switch module, which is installed on the left side of the frame and electrically connected to the gasoline engine body. A balance switch module electrically connected to the gasoline engine body is installed on the right side of the frame, and a manual switch electrically connected to the gasoline engine body is installed at the right end of the handle.

[0013] The utility model has at least the following beneficial effects:
[0014] 1. When the device is operating normally without any accidents, the staff holds the small handle with both hands, and then adjusts the angle between the small handle and the large handle to achieve a comfortable working angle. The staff can press the manual switch with their hands to control whether the gasoline engine body is working. When the device as a whole is accidentally lost, the field staff can control the remote control switch module through the remote control to shut down the gasoline engine body. When the field staff fails to react, the balance switch module can be set to make the device lose balance and work automatically, thereby shutting down the gasoline engine body.
[0015] By setting a series of coordinated settings of the switch control components, the remote control switch module, the balance switch module and the manual switch can control the gasoline engine body to achieve a triple insurance effect, thereby making the device safer during use.
[0016] 2. If the balance switch module fails due to an accident, the frame will rotate after the entire device fails. At this time, under the action of centrifugal force, the swing arm pin, the swing arm sleeve, the swing arm body and the first spring will make the swing arm body swing automatically. Then, through the cooperation of the safety anchor pin, the safety anchor body and the second spring, when the swing arm body swings to a certain angle, the swing arm body will release the lock on the safety anchor body position. At this time, the safety anchor body will be affected by its own gravity and the torsion of the second spring, so that the safety anchor body can fall to the lower end of the device, thereby locking the entire device.
[0017] By setting up a safety protection component, when multiple switches fail due to accidents, the entire device can be automatically locked, ensuring that the handle will no longer rotate if the entire device fails, thus solving the problem of injuries caused by the trowel handle.
