At present, China's high-altitude operation platform product is main with hand propelled still mostly, and volume and weight is all bigger; Change very difficulty of work-yard; Make troubles to user's use, can not be applicable to the aloft work in frequent change operation place, as: the aloft work of hand-held designs such as family or lounge; In building operation, construct to substitute scaffold; Decoration, cleaning and the maintenance on skin surface; Insulation stringing and maintenance; Fire-fighting and rescue and large-sized object are like maintenance inspection of boats and ships or aircraft etc.
Summary of the invention
The purpose of the utility model is exactly the self-propelled frame that a kind of high-altitude operation platform will be provided, and is applicable to the aloft work in frequent change operation place.
For realizing above-mentioned purpose; The self-propelled frame of the utility model institute design-calculated high-altitude operation platform comprises the chassis casing; The front end left and right sides of said chassis casing is provided with the driving wheel carrier; On the said driving wheel carrier drive wheel and Linkage steering are installed, said drive wheel links to each other with hydraulic drive motor, and said Linkage steering links to each other with hydraulic steering cylinder.The left and right sides, rear end of said chassis casing is provided with flower wheel, and the side of said flower wheel is provided with the stop hoof, and said stop hoof links to each other with the stop oil cylinder through the stop connecting rod.Be provided with motor-drive pump in the casing of said chassis, said hydraulic drive motor, hydraulic steering cylinder and stop oil cylinder all link to each other with motor-drive pump through hydraulic tubing.
Further, carry flat-bed stability when guaranteeing aloft work, the casing left and right sides, said chassis is provided with lands strut bar, and the said strut bar that lands links to each other with the strut bar hydraulic actuating cylinder, and said strut bar hydraulic actuating cylinder passes through hydraulic tubing and links to each other with motor-drive pump.
Again further, tilt safety misadventure takes place for preventing self-propelled frame, said chassis casing is provided with balance sensor.
The advantage of the utility model is: the self-propelled frame of institute's design-calculated high-altitude operation platform is provided with the driving wheel carrier through the front end left and right sides of the casing on the chassis; Said driving wheel carrier is provided with drive wheel and Linkage steering; The left and right sides, rear end of casing is provided with flower wheel on the chassis; The quick walking of job platform can be realized, and the 360 ° of turnings in original place can be realized.The casing left and right sides is provided with and lands strut bar on the chassis, and during aloft work, the strut bar that lands can land support automatically, stability when having increased aloft work greatly and safety.The chassis casing is provided with balance sensor, when the self-propelled frame run-off the straight, reports to the police immediately, can prevent the safety misadventure that self-propelled frame tilts to cause.Corresponding lifting mechanism is installed on the utility model and is carried platform, promptly can be used for aloft work.The utility model can be particularly suitable for the aloft work in frequent change operation place voluntarily through standard gate and passenger's elevator door.
