Abstract
The utility model relates to a working platform extension mechanism for a bridge inspection vehicle. The extension mechanism is installed on a fixed walking plate of a working platform and includes gear racks, a hydraulic motor, a gear and an installation seat, wherein the gear is installed on a transmission shaft of the hydraulic motor and rotates under the driving of the hydraulic motor; the hydraulic motor is installed on the installation seat; the installation seat is fixed below the fixed waling plate and hinged with the fixed walking plate; the gear is positioned below a movable walking plate; the gear racks are fixed at the bottom of the movable walking plate and meshed with the gear; and under the driving of the hydraulic motor, the gear drives the gear racks on the movable walking plate, so as to enable the movable walking plate to perform linear motion. The working platform extension mechanism for the bridge inspection vehicle adopting the technical scheme of gear-gear racks in charge of movable walking plate transmission has such advantages as convenience for operation, excellent stability, simple structure and convenience for maintenance.
Description
Technical field
The utility model relates to the parts of bridge inspection vehicle, particularly a kind of bridge inspection vehicle working platform telescoping mechanism.
Background technology
At present; Particularly the working platform telescoping mechanism on the bridge inspection vehicle uses the engineering special-purpose vehicle is roller type and chain type, and the roller type telescoping mechanism is walked platen through roller friction promotion activity, and activity is walked platen and fixedly walked when moving on the platen; Acceleration of gravity is arranged; Can not effectively be parked in certain a bit, perhaps impact limited block, cause the movable platform landing easily; There is the defective of easy chain rupture, poor stability in the chain type telescoping mechanism.
Summary of the invention
The purpose of the utility model is that a kind of bridge inspection vehicle working platform telescoping mechanism will be provided, and solves problems such as existing chain type and roller type telescoping mechanism poor stability, inconvenient maintenance, potential safety hazard are big.
The purpose of the utility model realizes like this: a kind of bridge inspection vehicle working platform telescoping mechanism; Telescoping mechanism is installed in working platform and fixedly walks on the platen, and telescoping mechanism is made up of tooth bar, hydraulic motor, gear and mount pad, and gear is installed on the hydraulic motor power transmission shaft; Rotate by the fluid motor-driven gear; Hydraulic motor is installed on the mount pad, and mount pad is located at fixedly walks platen below and with fixedly to walk platen hinged, gear is positioned at activity and walks the platen below; Platen bottom and gears engaged are walked in the tooth bar activity of being fixed on, and the tooth bar that gear drive activity under the driving of hydraulic motor is walked on the platen makes activity walk the platen rectilinear motion.
The beneficial effect of the utility model: bridge inspection vehicle working platform telescoping mechanism adopts gear-tooth bar transmission activity plate technique scheme of walking on stage, and has easy to operate, good stability, advantage such as simple in structure, easy to maintenance.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, platen is walked in activity, and 2, fixedly walk platen, 3, tooth bar, 4, hydraulic motor, 5, gear, 6 mount pads.
The specific embodiment
Referring to accompanying drawing 1; Bridge inspection vehicle working platform telescoping mechanism is installed in working platform and fixedly walks on the platen 2, and telescoping mechanism is made up of tooth bar 3, hydraulic motor 4, gear 5 and mount pad 6, and gear 5 is installed on the power transmission shaft of hydraulic motor 4; Rotate by hydraulic motor 4 driven wheels 5; Hydraulic motor 4 is installed on the mount pad 6, and mount pad 6 is located at fixedly walks platen 2 belows and with fixedly to walk platen 2 hinged, gear 5 is positioned at activity and walks platen 1 below; Platen 1 bottom and gear 5 engagements are walked in tooth bar 3 activities of being fixed on, and the tooth bar 3 that gear 5 is walked on the platen 1 in drive activity under the driving of hydraulic motor 4 makes activity walk platen 1 rectilinear motion.
