Abstract

The invention relates to the field of vacuum-machine machine frames, and discloses a vacuum machine unit machine frame with a bottom frame capable of being drawn. The vacuum machine unit machine framecomprises a main frame, the bottom frame located in the main frame and directional wheels located on the lower portion of the bottom frame. Turnover assemblies driving the directional wheels to overturn sideward are arranged on the lower portion of the bottom frame. Each turnover assembly comprises a guide base connected to the main frame and a turnover piece connected to the bottom frame in a pivoted manner. A first guide groove is formed in each guide base. Each turnover piece comprises a first connection section connected with the corresponding directional wheel, a pivoted connection section used for being connected with the bottom frame in a pivoted manner, a second connection section and a guide section matched with the corresponding first guide groove. Each first guide groove comprises a first lead-in section, a turnover section and a first lead-out section. The guide sections drive the directional wheels to overturn sideward when moving along the turnover sections, positioningpieces used for positioning the turnover pieces are connected to the bottom frame, a tangent plane is arranged on each turnover piece, the turnover pieces cannot rotate when the positioning pieces areconnected with the tangent planes in an abutting manner, a second guide part is arranged on each guide base, and the second guide parts and second guide grooves can cooperate to drive the positioningpieces to be separated from the tangent planes.

Description

technical field [0001] The invention relates to the field of vacuum machine frames, in particular to a vacuum machine unit frame with a drawable bottom frame. Background technique [0002] Vacuum machine is an important equipment and tool in the industry. One of the Roots pump vacuum machines is composed of oil rotary vane vacuum pump, Roots pump, mounting frame, etc. The oil rotary vane vacuum pump and Roots pump are in a high A low position is set and there is a connecting hard pipe between the two. The main frame is welded by twelve angle steels to form a cube. The oil rotary vane vacuum pump and the Roots pump are respectively installed on the top and inside of the frame. Maintenance is troublesome, and the Roots pump located inside the frame needs to be removed and removed. There is also a frame on the market that can pull out the vacuum pump. The frame includes a main frame, a bottom frame inside the main frame, and an oil The rotary vane vacuum pump and the Roots pum...
