The invention relates to a gravity center adjusting device for a ground grinding machine. The gravity center adjusting device comprises a lifting device, a support frame, a counter weight device and aflexible driving piece all arranged on a plane at the middle section of a rack; the support frame is arranged on the two sides of the lifting device and comprises two channel steel with opposite openings; the lifting device comprises a transverse lifting rod arranged on the top; pulleys are arranged at the two ends of the lifting rod and move up and down in the channel steel; the upper front endof the counter weight device is hinged to the rack; the upper end of the flexible driving piece is connected with the lifting rod; and the lower end of the flexible driving piece is connected with therear end of the counter weight device. The gravity center adjusting device has the following advantages: the electric lifting device is adopted, is stable in transferring, can bear the counter weightdevice with larger gravity, pulls and adjusts the counter weight device through a chain, can lock the counter weight device at any inclination angle, realizes stepless adjustment of counter weight ofthe grinding machine, saves labor, is high in efficiency, can conveniently adjust and maintain a grinding disc, is reliable and safe in action, and facilitates transportation and movement.
Description
technical field [0001] The invention relates to a ground grinding construction device, in particular to a gravity center adjustment device for a ground grinding machine. Background technique [0002] The ground grinder is a multifunctional machine that integrates different processes such as fast sealing and curing agent floors, hardened floors, epoxy floor treatment, stone renovation, concrete leveling, grinding, polishing, etc. It is light, flexible, and easy to work. Features such as high efficiency. [0003] At present, the commonly used ground grinders on the market include a frame. The front part of the frame is fixed with a motor drive device, which is connected to the grinding disc. There is a handrail at the rear and upper extension of the frame. When replacing the grinding head or abrasive, It is necessary to lift the handle and lower the pedal. The worker stands on the pedal and presses down with the gravity inertia of the whole body to realize the lifting of the ...
