Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 to 5, a chassis for a single-column fixed hydraulic lifting apparatus includes a main frame 1 having a U-shaped structure and two sub-frames 2 having a rectangular structure.
Four universal wheels 14 are symmetrically arranged on the main frame body 1, the main frame body 1 comprises a closed bending section and a straight section with an opening, the bending section is fixedly connected with a fixing plate 13, a plurality of sliding holes are arranged on the straight section, two auxiliary frame bodies 2 respectively correspond to the front side and the rear side of the straight section, a plurality of sliding rods 3 are fixedly connected in the auxiliary frame bodies 2, the sliding rods 3 are in sliding connection with the sliding holes, one side of each auxiliary frame body 2, which is far away from the center of the main frame body 1, is provided with a supporting foot component, the supporting foot component comprises four gears 4 rotatably connected on the auxiliary frame bodies 2, the gears 4 are rotatably connected with the auxiliary frame bodies 2 to form a conventional connecting structure, the connecting structure can fix the gear 4 on the auxiliary frame body 2 and can not move up and down and left and right, but does not influence the rotation of the gear, and specifically, a connecting circular pipe can be formed by extending the lower end of the gear 4, and the connecting circular pipe is inserted into the auxiliary frame body 2 and is rotationally connected with the auxiliary frame body 2 through a sliding bearing. Four gears 4 are arranged in a row and are meshed in sequence, a screw rod 5 is connected in each gear 4 in a threaded mode, the lower end of each screw rod 5 penetrates through the auxiliary frame body 2 and is fixedly connected with the supporting foot 6, the upper end of each screw rod 5 is fixedly connected with the stop block 12, the gear located at the leftmost end or the rightmost end in the row of gears 4 is a driving gear 400, and the upper end of the driving gear 400 is fixedly connected with a hand-operated wheel 7.
