Detailed description of the invention
The standardized element used in this utility model all can commercially, shaped piece according to
The record with accompanying drawing of description all can carry out customized, and the concrete connected mode of each part is all adopted
With bolt, rivet ripe in prior art, weld, the conventional means such as stickup, the most detailed at this
State.
With reference to Fig. 1-3, one detailed description of the invention of this utility model includes rectangular chassis 1, rectangular base
The outside of 1 four drift angles of frame is each provided with a guide wheel 2, and the top of 1 four drift angles of rectangular chassis is each
Being fixed with a support bar 3, two adjacent support bars 3 are symmetrical arranged, and support bar 3 top is passed through
Suspension rod 4 is fixed with job platform 5, between two support bars 3 of rectangular chassis 1 minor face both sides
It is provided with several horizon bars 6, sets between two support bars 3 of both sides, rectangular chassis 1 long limit
Being equipped with several reinforcements 7, reinforcement 7 joins end to end, and the adjacent angle between reinforcement 7 is
90 °, rectangular chassis 1 being additionally provided with two fixation clamps 8, guide wheel 2 is solid by head rod 9
Being scheduled in rectangular chassis 1, guide wheel 2 includes wheel hub 10, is provided with bearing 11 inside wheel hub 10,
Being provided with the second connecting rod 12 in bearing 11, the medial extremity of the second connecting rod 12 is provided with spherical appearance
