Description

Technical Field

[0001] The utility model belongs to the technical field of floor grinders, and particularly relates to a soft connection device between a grinding machine frame and a gearbox. Background Art

[0002] Floor grinders are mainly used for grinding the ground, and can effectively polish terrazzo, concrete surface layer, epoxy mortar layer and old epoxy floor, etc.

[0003] Since the hydraulic lifting gearbox of a conventional floor grinder adopts a hard connection, the vibration generated during its mechanical transmission will cause vibration and wear at the connection, resulting in the problem that the hydraulic lifting gearbox of a conventional floor grinder is prone to vibration and wear.

[0004] Therefore, we propose a soft connection device between a grinding machine frame and a gearbox to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that the hydraulic lifting gearbox of a conventional floor grinder is prone to vibration and wear, and to propose a soft connection device between a grinding machine frame and a gearbox.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A soft connection device between a grinding machine frame and a gearbox includes a box body. A soft rubber pad is padded on the upper part of the box body. A box cover is installed on the soft rubber pad. A first bolt is inserted through the box body, the soft rubber pad and the box cover. A first nut is threadedly installed on the upper part of the first bolt. A connecting pin is installed on the lower part of the box body. A soft rubber sleeve is sleeved on the lower part of the box body. The soft rubber pad is used to buffer the vibration between the box cover and the box body, which is convenient for protecting the box body and the box cover. By sleeving the soft rubber sleeve on the lower part of the box body, it is convenient to protect the lower part of the box body.

[0008] Preferably, first reinforcing plates are symmetrically and fixedly connected to the upper part of the box body. The first reinforcing plates are used to increase the stability of the upper structure of the box body.

[0009] Preferably, second reinforcing plates are symmetrically and fixedly connected to the upper part of the box cover. The second reinforcing plates are used to increase the stability of the upper structure of the box cover.

[0010] Preferably, a second bolt is movably inserted through the upper part of the box cover. The box cover is connected to an external device through the second bolt.

[0011] Preferably, a second nut is threadedly installed on the outside of the second bolt. Pass the second bolt through the target device, and then tighten the second nut on the second bolt to conveniently fix the box cover to the target device.

[0012] In summary, the technical effects and advantages of the present utility model are as follows: The vibration between the box cover and the box body is buffered by the soft rubber pad, reducing vibration wear and facilitating the protection of the box body and the box cover. The lower part of the box body is sleeved with a soft rubber sleeve, which facilitates the protection of the lower part of the box body. BRIEF DESCRIPTION OF THE DRAWINGS
