Embodiment 1

[0029] First, a first embodiment of an inversion preventing device according to the present invention will be described with reference to FIGS. 3 to 9 . As shown in Figure 3, the above-mentioned upside-down prevention device 10 includes a pair of upside-down prevention plates 11 installed on the vehicle body 2, a pair of left and right driving arms 12, and a first bracket on the unfolding operation part 14 and the scissor lift 4. 8 is installed on the storage operation part 15.

[0030] The inversion preventing plate 11 is composed of an elongated plate-shaped member extending in the vehicle front-rear direction, and has a shaft coupling portion 11a formed inside the inverting preventing plate 11 and extending upward, and a swing portion 11b extending inwardly. The shaft coupling portion 11a of the above-mentioned inversion preventing plate 11 is freely swingably mounted on the plate mounting portion 2a formed below the left and right sides of the vehicle body 2 . In addition...

Embodiment 2

[0047] Next, a second embodiment of an upside-down preventing device according to the present invention will be described with reference to FIG. 11 . Here, the same symbols are used for the same parts as those in the first embodiment, and detailed explanations are omitted. In the first embodiment, when the inversion preventing plate 11 is unfolded, the head 12b of the driving arm 12 is pushed up by the unfolding operation part 14, so that the outer part of the driving arm 12 is swung downward, but in the inversion of the second embodiment, In the arresting device 10', an expansion spring 14' is used. One end of the above-mentioned expansion spring 14' is fixed on the driving arm mounting part 2b of the vehicle body 2, and the other end is fixed on the outside of the shaft coupling hole 12a of the driving arm 12, so that the outer part of the driving arm 12 is pulled inward and swings downward. Therefore, when the lifting cylinder 7 starts to extend the operation to extend the...

Abstract

The invention relates to an anti-perversion device (10) used for an overhead working truck (1). The overhead working truck comprises a truck body which is provided with a front wheel and a rear wheel (3a and 3b) and walks forwards, and a fork-type lifting device (4) arranged on the truck body and used for lifting a working table (5). The invention comprises an anti-perversion board (11) arranged inside a vertical panel extending leftwards and rightwards below the truck body between the front wheel and the rear wheel in a free swing way and moved to a folding position and an unfolding position; a driving arm (12) whose external side part is connected with the anti-perversion board; an unfolding operation part (14) arranged on the truck body and used for pushing upwards the head (12b) of the driving arm so as to swing downwards to the external side part of the driving arm and swing the anti-perversion board towards to the unfolding position; and a folding operation part (15) arranged onthe lifting device and used for pressing downwards the head of the driving arm when the lifting device lifts downwards and swing upwards the external side part of the driving arm so as to swing the anti-perversion board to the folding position.

Description

technical field [0001] The invention relates to an upside-down preventing device for an aerial work vehicle that vertically lifts working equipment. Background technique [0002] The high-altitude operation vehicle has a scissors link type lift so that the work platform can be raised and lowered vertically, and the aerial work vehicle can travel in a state where the lift is extended to move the work platform to a high altitude, and can be used, for example, for maintenance installation in Lighting on the roof of a stadium or accessing supplies from the roof of a warehouse. When the above-mentioned aerial work vehicle is in a state where the lift is raised, if the wheel sinks into a dent or the like, the position of the center of gravity will shift and the stability will be impaired. Therefore, it is often necessary to install inversion prevention equipment (also called "equipment to prevent depression"). The pit will also prevent the wheel from sinking into the pit due to ...
