Beneficial effect

The beneficial effects of the facade cleaning device provided by the present invention.

It should be noted that when using the facade cleaning device, it is necessary to rely on a driving mechanism through which the installation main body is driven to move up and down or horizontally.

When the facade cleaning device is used to clean the surface to be cleaned (such as: curtain wall), the walking wheel and the cleaning part are in contact with the surface to be cleaned. Driven by the driving mechanism, the walking wheel can rotate, thereby driving the facade cleaning device to When traveling on the surface to be cleaned, in the process of traveling, because the sweeping element is pivotally connected to the frame, the sweeping element can rotate relative to the frame and clean the surface to be cleaned; in this process, when the traveling wheel travels over obstacles, due to the connecting element It is hinged to the frame at the third hinge point, the third hinge point is located at the first hinge point (the sweeper and the frame are pivotally connected to the first hinge point) and the second hinge point (the walking wheel and the frame are pivoted to the second hinge point) Point), and the elastic member is connected between the connector and the installation body (the connector and the installation body are hinged to the fourth hinge point).

Under the elastic force of the elastic piece, it can buffer the impact force between the traveling wheel and the frame. On the one hand, the frame will not drive the traveling wheel suddenly when it suddenly rises or falls due to inertia. Lifting or falling, so that the walking wheel always keeps in contact with the surface to be cleaned and can smoothly cross obstacles; on the other hand, it can reduce the impact of the facade cleaning device on the surface to be cleaned.

Furthermore, taking the linear drive assembly drive mechanism as a crane as an example, when in use, the installation body is installed on the crane arm. Due to the arrangement of the connecting piece and the elastic piece, when the crane arm approaches the surface to be cleaned, the installation The main body can squeeze the elastic element, and at the same time, the elastic element will give the installation main body a reverse action. Since the force perpendicular to the surface to be cleaned is offset by the elastic element, there will be no violent collision with the surface to be cleaned.

Example

This embodiment provides a facade cleaning device. With reference to Figures 1 and 2, the facade cleaning device includes a frame 100, a rolling brush assembly 200, a walking wheel 300, a connecting member 510, and an elastic member 600; the rolling brush assembly 200 includes The cleaning member 210 is pivotally connected to the frame 100 at a first hinge point; the walking wheel 300 is pivotally connected to the frame 100 at a second hinge point; the connecting part 510 is hinged to the frame 100 at a third hinge point, and the third hinge point The hinge point is located between the first hinge point and the second hinge point; the connecting member 510 and the mounting body 700 are hinged to the fourth hinge point; the elastic member 600 is connected between the connecting member 510 and the mounting body 700.

It should be noted that, when using the facade cleaning device, a driving mechanism is required to drive the installation main body 700 to move up and down or horizontally through the driving mechanism.

When the facade cleaning device is used to clean the surface to be cleaned (such as a curtain wall), both the walking wheel 300 and the cleaning member 210 are in contact with the surface to be cleaned. Driven by the driving mechanism, the walking wheel 300 can rotate, thereby driving the facade The cleaning device travels on the surface to be cleaned. In the process of traveling, since the cleaning member 210 is pivotally connected to the frame 100, the cleaning member 210 can rotate relative to the frame 100 and clean the surface to be cleaned; in this process, when the walking wheel 300 When driving over obstacles, since the connecting member 510 and the frame 100 are hinged at the third hinge point, the third hinge point is located at the first hinge point (the cleaning element 210 and the frame 100 are pivotally connected to the first hinge point) and the second hinge point (The traveling wheel 300 and the frame 100 are pivotally connected to the second hinge point), and the elastic member 600 is connected between the connecting member 510 and the installation body 700. When the traveling wheel 300 drives the frame 100 to lift or fall, the The wheel 300 can drive the frame 100 to rotate relative to the connecting member 510 and squeeze the elastic member 600. Under the elastic force of the elastic member 600, the impact force between the traveling wheel 300 and the frame 100 can be buffered. On the one hand, the frame 100 Because the inertia suddenly lifts or falls, it will not drive the traveling wheel 300 to suddenly lift or fall, so that the traveling wheel 300 always keeps in contact with the surface to be cleaned and can smoothly cross obstacles; on the other hand, it can reduce facade cleaning The impact force of the device on the clean surface.

Furthermore, taking the linear drive assembly drive mechanism as a crane as an example, when in use, the mounting body 700 is installed on the crane arm. Due to the arrangement of the connecting member 510 and the elastic member 600, when the crane arm approaches the surface to be cleaned When the installation main body 700 can squeeze the elastic member 600, the elastic member 600 will give the installation main body 700 a reverse action.
