Abstract

The invention provides an adjustable supporting frame. The adjustable supporting frame comprises a top plate, a rear plate, side vertical plates, an adjusting port baffle and rib plates. The top plateis rectangular. The two ends of the top plate are provided with two rectangular grooves. The rear plate is perpendicularly welded to the top plate and is flush with rectangular guide grooves. The twoside vertical plates are perpendicularly welded to the rear plate and the top plate and are flush with the two sides of the rear plate. The two rib plates are perpendicularly welded to the top plateand the rear plate with the center line of a center hole as the symmetry axis. The adjusting port baffle is perpendicularly welded to one end of the top plate and one ends of the rib plates to form the adjustable supporting frame. When a chain mechanism gets too loose and exceeds the adjusting distance of a lifting mechanism, the adjustable supporting frame is jacked up through a jacking device and moves along a guide rail. The maximum moving distance is equal to the length of adjusting grooves of the rear plate. Thus, there is no need to manually cut off a chain within certain range. The adjustable supporting frame is easy, convenient and reliable to adjust.

Description

technical field [0001] The invention relates to a support frame of a scraper mechanical tensioning device, in particular to an adjustable support frame which can be moved to adjust the tensioning distance. Background technique [0002] At present, the known support frame technology is a fixed non-adjustable support frame, which is composed of a top plate, a side plate, and a rib plate. The long sides of the top plate and the side plate are aligned and welded together, and the two rib plates are welded symmetrically and vertically on the top plate and the side plate. Above, the lifting device such as hydraulic lifting mechanism is installed on it, and the position of the tensioning device is adjusted by the lifting of the jack rod of the hydraulic lifting mechanism, so as to achieve the purpose of adjusting the tightness of the chain. The disadvantage of this technology is that when the chain is over When loosening exceeds the lifting distance of the mandrel of the lifting me...
