Anti-jam mechanism for controlling lifting of brush plate of ground washing vehicle

Abstract

The invention provides an anti-jam mechanism for controlling lifting of a brush plate of a ground washing vehicle. The anti-jam mechanism includes a vehicle frame, a connecting rod and a rotating plate, and a convex block is arranged on the rotating plate; in the process in which a clamping hook moves to a clamping groove so as to be clamped in the clamping groove, when a guide wheel moves to be about to be in contact with a position-limiting surface, the convex block pushes against the guide wheel so as to make a guide wheel axial section which is parallel to a guide surface located beyond the position-limiting surface, therefore, the position-limiting surface will not jam the guide wheel and thus not limit the guide wheel to move toward the guide surface, the guide wheel can be smoothly transmitted from the position-limiting surface to the guide surface so as to achieve the smooth clamping connection of the clamping hook and the clamping groove, the brush plate can be smoothly lifted in place, and the cleaning efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of floor washing vehicles, in particular to an anti-jamming mechanism for controlling the lifting and lowering of the brush plate of the floor washing vehicle. Background technique [0002] With the development of society, environmental sanitation is an important factor affecting the quality of life. Therefore, with the continuous improvement of people's requirements for quality of life, the requirements for environmental sanitation are also getting higher and higher. The rapid increase, it is urgent to be liberated from the heavy cleaning work, so there are many equipment for cleaning the ground to improve the environmental sanitation. The floor washing car is commonly used to clean the ground. The cleaning efficiency is high, which can greatly reduce the labor intensity of cleaning personnel and win the favor of the people. Floor washing vehicles are widely used in indoor places in service industries such...

Problems solved by technology

[0005] Invention idea: the applicant found that before the guide wheel contacts the guide surface, the guide wheel first contacts the limit surface, so that the limit surface can easily block the guide wheel, so that the guide wheel cannot continue to move downward along the guide surface, so The hook just cannot be stuck in the draw-in groove. To solve this problem, the applicant sets a bump on the rotating plate. When the guide wheel moves to be about to contact with the limit surface, the bump pushes against the guide wheel, so that the guide wheel will not be in contact with the guide surface. The axial section of the parallel guide wheels is located outside the guide surface, so that the guide wheels can smoothly transition from the limit surface to the guide surface
