The invention relates to a tractor for a torch platform lifting mechanism, which comprises a frame, wherein the front end of the frame is provided with a third pulley; the top of the frame is provided with a draw hook; both sides of the bottom of the frame are respectively provided with a front traveling wheel and a rear traveling wheel which are arranged in the longitudinal direction and match with the lower guide face of the guide rail; both sides of the front part of the frame draw hook are symmetrically provided with upper guide wheels which match with the upper guide face of the guide rail; the upper guide wheels are arranged between the front traveling wheel and the rear traveling wheel and adjacent to the front traveling wheel; the diameter of the front traveling wheel is smaller than that of the rear traveling wheel; the connecting line of the rim bottoms of the front and rear traveling wheels is parallel to the lower guide face of the guide rail; and the vertical distance between the highest point of the rims of the upper guide wheels and the lowest point of the rim of the front traveling wheel is equal to the vertical distance between the upper guide face and the lower guide face of the guide rail. The draw hook on the tractor matches with the middle section of the axle of the bearing wheel, thereby transferring power and limiting the transverse freedom degree of thecambered rack on the ground, and thus, the cambered rack is pulled to move along the guide rail to the preset position to form an arched top. The tractor of the invention has the advantages of simplestructure and is convenient in operation.
Description
(1) Technical field [0001] The invention relates to equipment used in a celebration ceremony at the opening of a large-scale sports meeting, in particular to a tractor used for a torch stand jacking mechanism used in an ignition ceremony.
