Abstract
The utility model relates to an aloft work platform, comprising a machine body, a running device, an elevating device and a work platform. The upper end of the elevating device is connected with the work platform. The utility model is characterized in that the platform also comprises a safe mechanism which comprises two safe boards and at least one transmission device unit. And when the work platform is not elevated, the safe boards are in a horizontal state and are far away from the ground, which is good for the running of the aloft work platform so as to avoid the block of an outshoot on the ground. When the work platform is elevated, the safe boards are in a vertical state and are near the ground and then the safe board can be used as braces on ground to keep a truck body from inclining when wheels touch potholes.
Description
Technical field
The utility model belongs to lifting machinery, particularly relates to a kind of high-altitude operation platform.
Background technology
Existing high-altitude operation platform comprises fuselage, running gear, jacking system and job platform, the upper end of described jacking system is connected with described job platform, jacking system can be scissor-type jacking system, column type jacking system or sleeve-type jacking system, and running gear can be a wheel formula running gear.The body bottom section of this high-altitude operation platform is bigger apart from ground distance, because when the walking of high-altitude operation platform, may there be some outstanding obstacles on the ground, such as hill or stone etc., distance ground-surface bigger distance in bottom can avoid the walking of high-altitude operation platform to be obstructed, just as the chassis of automobile must be apart from the ground certain altitude during with the protrusion that prevents to face the mountain with running into by stranded.But, brought the unsafe problems in the use for the aerial working platform vehicle body bottom distance bigger apart from ground.Because when the work of high-altitude operation platform, job platform rises very highly, and the staff stands in and carries out various required work on the platform.In the working process, may need mobile high-altitude operation platform, when mobile, the staff still rests on the job platform that is in high position very.If some hollow of the ground of working space, even very little hollow, because the wheel diameter of high-altitude operation platform is not very big, wheel can fall into hollow, and this can make the vehicle body run-off the straight, and the inclination of on the ground very little, pass to all can become when being in high-order job platform and be very big displacement and inclination, the lighter has no a sense of safety the staff, when serious, so because high-altitude operation platform when rising very high center of gravity higher, the danger that can topple.If can be designed to the distance less apart from ground to high-altitude operation platform to body bottom section can avoid this problem certainly, but, if this distance is less, when high-altitude operation platform does not rise, when its from the machine works of parking high-altitude operation platform or other places to the driving process of so long distance such as is travelled in the working space, if run into protrusion is arranged on the ground, thereby body bottom section can be met these protrusions and makes car load be obstructed by stranded.This has constituted a pair of unsolved always for many years contradiction.
Summary of the invention
The purpose of this utility model provides a kind of high-altitude operation platform, can be not stranded in the walking process before this high-altitude operation platform does not rise by ground protrusion, can not be subjected to the threat of ground hollow during walking after rising again, the inclined degree of the aerial working platform vehicle body when promptly having reduced as best one can to run into hollow.
