Description
Technical field
The quick lift platform of a kind of bridge inspection vehicle of the present invention belongs to the bridge inspection apparatus field, particularly bridge lower edge inspection trolley.
Background technology
At present, the most frequently used checkout facility to the bridge edge of a wing and oblique web in domestic and abroad bridge field has Simple crawling ladder and bridge inspection vehicle etc.But its examination scope of Simple crawling ladder commonly used is limited because bottom that can not the full maintenance arch bridge, so can't carry out full section inspection to bridge, use also inconvenient, inefficiency; Existing mobile scissor aerial work platform, although can carry out bridge inspection, because the bottom is not fixed with the inspection trolley vehicle frame, because wind carries the impact of moving with inspection trolley, stability is not good yet, makes it to reexamine to check the bridge edge of a wing in the car moving process.And area of platform is little, structure is heavy.Now need can to check simultaneously the bridge edge of a wing under a kind of easy to operate, area of platform, can move in the bridge inspection vehicle lift platform of inspection, light in structure, good stability.
Summary of the invention
The invention provides the quick lift platform of a kind of bridge inspection vehicle, to realize that inspection trolley moves the quick lifting of stablizing of middle working platform, satisfy 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, the foldable crane, electric pushrod mechanism and base, described foldable crane is comprised of travelling carriage, slide mechanism, bracing frame, link, brace, bracing frame is connected to form by two joint bracing frames up and down, 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 travelling carriage is connected the lower end and is connected with the base bearing pin to be separately fixed at and connects the inspection trolley vehicle frame with bracing frame; Link is horizontally disposed with, and the one end is connected with the link bearing pin of upper and lower joint bracing frame, consists of the break of bracing frame one side; Its other end is connected bearing pin with the brace lower end and is connected with travelling carriage, is the break of travelling carriage one side; This jib head is connected with the upper mounting plate bearing pin; The electric pushrod end of electric pushrod mechanism is connected with the travelling carriage bottom, and flexible by electric pushrod, travelling carriage slides along upper mounting plate, makes the foldable crane stretch or fold at the break place, thereby realizes the quick lifting of working platform.
Described slide mechanism is comprised of pulley, connecting axle, and pulley is installed in the travelling carriage top by connecting axle, and travelling carriage is slidingly matched by its top pulley and upper mounting plate.
Described upper mounting plate is provided with the chute that cooperates with travelling carriage top pulley.
Described electric pushrod mechanism is comprised of electric pushrod and the Connection Block of band brake, and the electric pushrod of band brake is connected with Connection Block by bearing pin and is fixed on the inspection trolley vehicle frame.
The quick lift platform of a kind of bridge maintenance of the present invention, to have mobile scissor aerial work platform now, Creative Design is can be in the folded truss structure of inspection trolley moving process use, it is strong to have stability, working platform is large, can in moving, inspection trolley check the bridge edge of a wing, safe characteristics, base and Connection Block with lift platform is fixed on the inspection trolley vehicle frame first, when needs check bridge, the travelling carriage that electric pushrod promotes the foldable crane rises around break, the slide mechanism at travelling carriage top is slip jack-up upper mounting plate one end in the chute of upper mounting plate, travelling carriage drives respectively brace and link, link drives bracing frame and rises around break, the other end of jack-up upper mounting plate, whole like this upper mounting plate rises to the operating position, at this moment the electric pushrod of band brake stops action, the brake that the electric pushrod of band brake carries locks electric pushrod, electric pushrod mechanism and travelling carriage are fixed on by base and Connection Block and form a stable triangular structure on the inspection trolley vehicle frame, guaranteed the firm of upper mounting plate, then staff's working face of climbing upper mounting plate by the cross bar on the bracing frame just can overhaul the bridge edge of a wing, otherwise, the electric pushrod retraction, upper mounting plate can descend; Even in the inspection trolley moving process, because the lift platform bottom is fixed on the support good stability, the staff need not to get off just can continue bridge is overhauled from upper mounting plate again, and whole operation use procedure is simple, safe and reliable, high efficiency not only, and integrated cost is low.
