At present, the most frequently used checkout facility to the bridge edge of a wing and skew web plate in domestic and abroad bridge field has Simple crawling ladder and bridge inspection vehicle etc.But conventional its examination scope of Simple crawling ladder is limited, due to can not the bottom of full maintenance arch bridge, so tunneling boring inspection cannot be carried out to bridge, use also inconvenient, inefficiency; Existing mobile scissor aerial work platform, although can carry out bridge inspection, because bottom is not fixed with inspection trolley vehicle frame, because wind carries the impact with inspection trolley movement, stability is not good yet, makes it can not reexamine in car moving process to check the bridge edge of a wing.And area of platform is little, structure weight.The bridge edge of a wing can be checked under now needing a kind of easy to operate, area of platform simultaneously, middle inspection can be moved, structure is light, the bridge inspection vehicle lift platform of good stability.
Summary of the invention
The invention provides the quick lift platform of a kind of bridge inspection vehicle, to realize the stable quick lifting that inspection trolley moves middle working platform, meet the needs to the high efficiency examination and maintenance of bridge bottom.
The present invention adopts following technical scheme:
The quick lift platform of a kind of bridge inspection vehicle of the present invention, comprise upper mounting plate, foldable crane, electric pushrod and base, described foldable crane is made up of travelling carriage, slide mechanism, bracing frame, link, brace, bracing frame is connected to form by upper and lower two joint bracing frames, its upper end is connected with upper mounting plate by bearing pin, travelling carriage is by its upper end slide mechanism and upper mounting plate sliding connection, and the lower end of travelling carriage and bracing frame and base pinned connection are separately fixed at and connect inspection trolley vehicle frame; Link is horizontally disposed with, the link pinned connection of its one end and upper and lower joint bracing frame, forms the break of bracing frame side; Its other end is connected with travelling carriage by bearing pin with brace lower end, is the break of travelling carriage side; This jib head and upper mounting plate pinned connection; The electric pushrod end of electric pushrod is connected with travelling carriage bottom, and stretched by electric pushrod, travelling carriage slides along upper mounting plate, makes foldable crane stretch at break place or fold into, thus realizes the quick lifting of working platform.
Described slide mechanism is made up of pulley, connecting axle, and pulley is arranged on travelling carriage top by connecting axle, and travelling carriage is slidably matched by its top pulley and upper mounting plate.
Described upper mounting plate is provided with the chute coordinated with travelling carriage top pulley.
Described electric pushrod is made up of the electric pushrod of band brake and Connection Block, and the electric pushrod of band brake is connected with Connection Block by bearing pin and is fixed on inspection trolley vehicle frame.
The quick lift platform of a kind of bridge maintenance of the present invention, by existing mobile scissor aerial work platform, Creative Design is the folded truss structure that can use at inspection trolley moving process, there is stability strong, working platform is large, can check the bridge edge of a wing in inspection trolley moves, the feature that safety is high, first the base of lift platform and Connection Block are fixed on inspection trolley vehicle frame, when needs check bridge, the travelling carriage that electric pushrod promotes foldable crane rises around break, the slide mechanism at travelling carriage top slides jack-up upper mounting plate one end in the chute of upper mounting plate, travelling carriage drives brace and link respectively, link drives bracing frame to rise around break, the other end of jack-up upper mounting plate, whole like this upper mounting plate rises to operating position, at this moment the electric pushrod of band brake stops action, electric pushrod locks by the brake that the electric pushrod of band brake carries, electric pushrod and travelling carriage are fixed on by base and Connection Block and inspection trolley vehicle frame form a stable triangular structure, ensure that the firm of upper mounting plate, then the working face that staff climbs upper mounting plate by the cross bar on bracing frame just can overhaul the bridge edge of a wing, otherwise, electric pushrod bounces back, upper mounting plate can decline, even if in inspection trolley moving process, because lift platform bottom is fixed on support, good stability, staff is without the need to getting off just can continue to overhaul bridge from upper mounting plate again, and whole operation use procedure is simple, safe and reliable, not only operating efficiency is high, and integrated cost is low.
