The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1 to 6, the aerial work platform swing mechanism according to the embodiment of the present invention includes a frame 100, and a work platform 200 is installed on the upper portion of the frame; a rotating arm 210 is arranged at the center of the working platform 200, one end of the rotating arm 210 is rotatably connected with the rack 100, the other end of the rotating arm 210 is hinged with a movable connecting rod 220, and the other end of the movable connecting rod 220 is hinged with a driving connecting rod 230; one end of the driving link 230 far away from the movable link 220 is hinged with the frame 100; and the electric push rod 300 is installed on the frame 100, is hinged to the middle of the driving connecting rod 230, and is used for driving the driving connecting rod 230 to move and finally driving the working platform 200 to rotate relative to the frame 100. Specifically, as shown in fig. 4, the rotating arm 210 is rotatably connected to the rack 100 through a point O, one end of the movable connecting rod 220 is hinged to the rotating arm 210 at a point C, the other end of the movable connecting rod is hinged to the driving connecting rod 230, and the other end of the driving connecting rod 230 is hinged to the rack 100 at a point B; one end of the electric push rod 300 is hinged with the driving connecting rod 230, and the other end is hinged with the frame 100 at the point A. The electric push rod 300 drives the driving link 230 to move, the driving link 230 further drives the movable link 220 to move, and the movable link 220 thereby drives the rotating arm 210 to rotate around the connection between the rotating arm and the frame 100 and drives the working platform 200 to rotate around the center thereof relative to the frame 100. The high-altitude working platform 200 swinging mechanism is simple in structure, and compared with a common hydraulic swinging motor, the high-altitude working platform 200 swinging mechanism is lighter in overall weight, is arranged at the lower part of the working platform 200, cannot generate overturning moment on the working platform 200, can improve the stability of the whole vehicle, and cannot influence the load capacity of the working platform 200; and the swing mechanism of the invention does not adopt precise elements, is more economical and practical compared with hydraulic pushing, and can effectively reduce the use cost and the maintenance cost.
It is understood that the rotating arm 210 may be fixedly disposed on the working platform 200 or detachably connected to the working platform 200.
In some embodiments of the present invention, the rotating arm 210 is provided with a mounting hole 211, and the mounting hole 211 coincides with the center of the working platform 200; the frame 100 is provided with a connecting shaft 110, and the connecting shaft 110 is installed in the installation hole 211 to realize the connection of the frame 100 and the working platform 200. Specifically, since the working platform 200 is disposed at the upper portion of the frame 100, and a gap is left between the frame 100 and the working platform 200 for the movable connecting rod 220 and the driving connecting rod 230 to move, the connecting shaft 110 engaged with the mounting hole 211 should be longer than the diameter of the mounting hole 211, so that a gap is left between the frame 100 and the working platform 200.
In some embodiments of the present invention, the power putter 300 includes a rod body 310 and a telescopic rod 320, wherein the rod body 310 is hinged to the frame 100, one end of the telescopic rod 320 is hinged to the driving link 230, and the other end is installed in the rod body 310. Specifically, one end of the rod body 310, which is far away from the telescopic rod 320, is connected with the other end of the rod body 310, or an electric driving device is arranged in the rod body 310, and the telescopic rod 320 is driven by electric power to stretch.
In some embodiments of the present invention, the driving link 230 is provided at a middle portion thereof with a hinge hole 231 protruding radially, and the expansion link 320 is hinged at the hinge hole 231. The hinge hole 231 is disposed at one end of the driving link 230 close to the frame 100, and the movement range of the driving link 230 close to the frame 100 is relatively small, so that the telescopic rod 320 of the electric putter 300 does not need to be too long, the telescopic rod 320 is not easily deformed, and a relatively large moment can be transmitted.
In some embodiments of the present invention, the work platform 200 can rotate left and right, respectively, no less than 90 degrees about its center. Specifically, the swing angle range of the existing working platform 200 is mostly about 160 °, and the larger the swing angle range of the working platform 200 is, the larger the swing angle range is, the working range is increased without moving the rack 100, and the more flexible adjustment can be performed for different environments, so that the working platform is suitable for more complicated conditions.
In a further embodiment of the present invention, as shown in fig. 5 and 6, the rack 100 is provided with a balance roller 400, the balance roller 400 includes a housing 410 and a roller 420, the housing 410 is mounted on the rack 100, the roller 420 is disposed in the housing 410, and the roller 420 abuts against the working platform 200; the balance roller 400 is used to support the work platform 200, so that the work platform 200 is stressed in a balanced manner. It should be understood that the balance roller 400 should not be disposed on the moving path of the driving link 230 and the movable link 220.
