Description
Technical field
The present invention relates to the self-propelled aloft working platform chassis.
Technical background
Self-propelled aloft working platform is widely used in the industries such as Ship Building and Repairing, engineering construction, industry installation, overhaul of the equipments.In order to improve the working stability of self-propelled aloft working platform, generally need to strengthen the wheel gauge, but wheelspan is fixed and larger high-altitude operation platform transport performance is poor.Therefore, the wheel gauge on chassis needs scalable, improves the stability of operation and the comfort feature of transportation.
Patent No. ZL200720177872.0 provides a kind of underpan traveling system for altitude operation vehicle, be the four wheel drive mode, it takes turns the gauge telescoping mechanism, and can automatically to finish the wheel gauge in the process of travelling flexible, its telescopic oil cylinder is the double piston-rod structure, the telescopic oil cylinder cylinder barrel is fixed on the chassis, and oil cylinder is made and install complicated.
Patent No. ZL200820035630.2 and 200810025198.3 provides a kind of chassis that can automatically keep the self-propelled aloft working platform of turn table balance, adopt the moving bridge construction of double pendulum, to be articulated on the vehicle frame, three six logical control cock are installed on its back axle, and the control lever of control cock and rear-axle hinging, be difficult to form feedback, action response accuracy and runtime aspect Shortcomings, and it takes turns the flexible of gauge also is to have adopted jacking cylinder system, complex structure, inefficiency.
Summary of the invention
The problem of solution required for the present invention is, overcomes now technical deficiency, and a kind of self-propelled aloft working platform chassis is provided, and can realize in the process of moving taking turns the flexible, reliable and stable of gauge.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: high-altitude operation platform adopts the four wheel drive mode, is divided into four half-bridges all around; The front left half-bridge all is to be connected by a common oil cylinder with front right half-bridge, rear left half-bridge with the rear right half-bridge; Half-bridge is equipped with slide block all around and slides in vehicle frame smoothly; Be welded with the annular stop piece on the half-bridge, the stroke that slides by the restriction half-bridge that is fixed on the bearing pin machinery on the vehicle frame; On the vehicle frame four half-bridges are equipped with four approach switchs, detect the situation that slides of half-bridge, behind the flexible Overstroke of half-bridge, also keep locking by electric-control system cut-out oil circuit, thereby reach the purpose of the automatically controlled and mechanical double-locking of wheel gauge variation.
Advantage of the present invention is simple in structure, with low cost, successful, safe.
