The purpose of this utility model is achieved in that a kind of collapsible aerial work platform, it comprises job platform (3), flat car (1), pivoting support and hydraulic mechanism, it also is provided with plural support arm, each arm room is hinged, drive by oil cylinder (4) between corresponding two support arms, the both sides that are adjacent two support arms are provided with the oil cylinder (4) that symmetry is installed, the bottom of its oil cylinder (4) connects with lower branch arm, the piston rod and the upper branch arm of oil cylinder (4) link, support (2) on the top bottom-disc of nethermost support arm and pivoting support (10) is hinged, nethermost support arm is driven by the oil cylinder that is located at its both sides (4), the bottom of oil cylinder (4) and top bottom-disc (10) link, the piston rod and the nethermost support arm of oil cylinder (4) link, the low bottom-disc of pivoting support (8) is fixed on the flat car (1), and topmost the top of support arm is provided with hinge and makes itself and job platform (3) hinged.
Support arm is by upper branch arm (7), and middle support arm (6) and lower branch arm (5) are formed.Also be provided with balance rope (11) between job platform (3) and the pivoting support, respectively be provided with a stabilizer (12) in the both sides of each support arm hinge, hinge two ends between middle support arm (6) and lower branch arm (5) respectively are provided with two directive wheels (13), one end of balance rope (11) is through stabilizer (12), directive wheel (13) and adjust screw (14) and connect with top bottom-disc (10) on being located at pivoting support, the other end be fixedly mounted on the fastening stabilizer that connects of job platform (3) (12) on, on stabilizer (12), also be installed with balance rope (11) around to opposite extension spring (15), the other end of its extension spring (15) is assemblied on the upper branch arm (7) through adjusting screw (16).Pivoting support is made up of top bottom-disc (10), low bottom-disc (8) and pivoting support (9).Also be equipped with hydraulic power unit, balancing weight, power distribution cabinet and one group of action bars on the top bottom-disc of pivoting support (10).
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a user mode schematic diagram of the present utility model.
Fig. 2 is a folded state schematic diagram of the present utility model.
Fig. 3 is a job platform balance schematic diagram.
As Fig. 1, Fig. 2, shown in Figure 3, the four rolling of flat car contacts with track, the low bottom-disc of flat car and pivoting support seat is fixedly connected, be fitted with power distribution cabinet on the top bottom-disc of pivoting support seat, hydraulic power unit, balancing weight, one group of action bars and a pair of triangular shape support, be provided with a hinge between two triangle supports, make itself and lower branch arm hinged, during present embodiment also is provided with and upper branch arm, all adopt hinged between its each arm room and upper branch arm and job platform, simultaneously, all be respectively fitted with symmetrical oil cylinder in the both sides of lower branch arm bottom and the both sides of adjacent two support arms, the fastening respectively top bottom-disc that is installed in the bottom of its each oil cylinder, on lower branch arm and the middle support arm, the fastening respectively lower branch arm that is installed in the top of the piston rod of oil cylinder, on middle support arm and the upper branch arm.In order to guarantee the job platform degree of balance in use, between job platform and top bottom-disc, assembled balance rope through 4 pairs of stabilizers and four directive wheels, one end of its wire rope connects with top bottom-disc is fastening through adjusting screw, the other end is fixed on the stabilizer after 3/4 week around the stabilizer that is installed on the job platform, so formed a cornerite between stabilizer and wire rope, promptly utilize the action of the cornerite of each stabilizer and directive wheel and angle of release to realize the balance of job platform.Also be equipped with on the fastening stabilizer that is installed on the job platform in addition around to the extension spring opposite with wire rope, an end of its extension spring is fixed on the stabilizer, and the other end is fastened on the upper branch arm through adjusting screw.
