Detailed Description
As shown in fig. 1, the present embodiment is a work vehicle platform on a work surface with a certain slope.
The hook 2 at the front end of the bottom plate 4 of the trolley platform is connected with a steel wire rope 19 of the winch 1, and the winch 1 provides power for the movement of the trolley platform. The hinge base 16 of the trolley bottom plate 4 is hinged with one end of the rear wheel supporting rod 14 to form a hinge. The rear wheel support lever 14 is free to rotate about the hinge base 16. A sleeve supporting rod 8 is installed at the rear end of the trolley bottom plate 4, and a hinge seat 9 on the sleeve supporting rod 8 is hinged with the sleeve 6 to form a hinge. The sleeve 6 is free to rotate about the hinge mount 9. The other end of the rear wheel support rod 14 is rigidly connected with the axle of the rear wheel 13, so that the axle of the rear wheel 13 cannot swing relative to the rear wheel support rod 14, but auxiliary structures such as a certain buffer structure are not excluded. A hinge seat 15 at the midpoint of the rear wheel support rod 14 is hinged with one end of the slide rod 5 to form a hinge, and the other end of the slide rod 5 passes through the sleeve 6. The slide rod 5 can slide along the sleeve 6 while being rotatable about the hinge mount 15. The slide bar 5 is marked with scales, and different scales correspond to different slopes. A plurality of bolt holes are formed in the sleeve 6, and the peripheries of the bolt holes need to be locally thickened to lengthen the bolt stroke. By adjusting the relative position of the sliding rod 5 and the sleeve 6, the relative position of the rear wheel supporting rod 14 and the rear wheel 13 and the trolley bottom plate 4 can be adjusted, so that the trolley platform bottom plate 4 can be kept horizontal on working surfaces with different gradients. When the slide bar 5 drives the rear wheel support bar 14 and the rear wheel 13 to proper positions, the fastening bolt 10 is screwed down, and the whole trolley is locked.
The size of the outer edge of the cross section of the sliding rod 5 is slightly smaller than that of the inner edge of the cross section of the sleeve 6, and the outer edge of the cross section of the sliding rod 5 and the inner edge of the cross section of the sleeve 6 are preferably rectangular or nearly rectangular, so as to enhance the friction force between the fastening bolt 10 and the sliding rod 5 and between the outer surface of the sliding rod 5 and the inner surface of the sleeve 6.
The bottom plate 4 is provided with a ceiling bracket 7, the ceiling bracket 7 is provided with a ceiling 3, and the ceiling 3 can be used for preventing rain and sun.
Carrying out structural analysis on the trolley platform mechanism:
the total number of mechanism parts K of the trolley platform is 4[ the bottom plate 4, the slide rod 5, the sleeve 6 and the rear wheel support rod 14 ]]The number of movable members n-K-1-3, including the lower pair PL4 (revolute pair and revolute pair), high pair PH0, the degree of freedom F of the trolley platform is 3n-2PL-P H3 × 3-2 × 4-0-1, no further movement occurs when the slide bar 5 of the trolley is locked.
The slide bar 5 is marked with scales, and different scales correspond to different slopes. The marking method of the scales of the sliding rod is as follows:
①, according to the specific design dimension parameters of each component, a structure diagram similar to that of figure 1 is formed in drawing software, and the diagram requires the dimension parameters of each component to be accurate.
②, adjusting the rear wheel support bar 14 and the slide bar 5 in the drawing, adjusting the trolley platform to the working state corresponding to the minimum gradient and the maximum gradient, respectively recording the working length [ which can be defined as the length between the outlet of the sleeve 6 and the hinge base 15 ] of the corresponding slide bar 5, and determining the difference between the two working lengths as the working range of the corresponding trolley platform.
③, within the working range of the trolley platform, the rear wheel supporting rod 14 and the sliding rod 5 are adjusted according to a certain gradient difference, and the working lengths of the corresponding sliding rods 5 under different gradients are recorded respectively.
④, drawing the recorded data on the slide bar 5 by clear scale lines for the use when the working face gradient of the trolley platform changes.
