Abstract
The utility model discloses a rail-crossing locking device of a bridge crane. The rail-crossing locking device comprises a main vehicle girder and an auxiliary vehicle girder, wherein a motor and a speed reducer are mounted on the main vehicle girder; a pinion is arranged on an output shaft of the speed reducer and is fixed through a mandrel of an upper girder flange plate; a rack wheel is fixed through the mandrel of the upper girder flange plate and is meshed with the pinion to rotate; a positioning plate is arranged on the rack wheel; a connection rod is mounted on a main vehicle girder web; a baffle is hinged to the connection rod; an auxiliary girder web is hinged with an auxiliary vehicle baffle; a positioning slot is formed in the auxiliary vehicle girder; the lower end of the baffle is linear, and the upper end of the baffle is arc-shaped. By adopting motor driving and a crank rocker mechanism, the rail-crossing locking device realizes rail-crossing running of a lifting trolley of the bridge crane on the main vehicle girder and the auxiliary vehicle girder; meanwhile, locking and limiting are implemented through the positioning plate; the rail-crossing locking device is compact in structure, easy to operate, positioned accurately, long in service life and safe and reliable in performance.
Description
Technical field:
The utility model relates to a kind of rail blocking device of crossing, and is specially adapted to use on crane in bridge type.
Background technology:
Common crane in bridge type is that end carriage operates in the horizontal operation that realizes cart on the track of factory building bracket, and lifting trolley (electric block) article hoisting is longitudinally operation on girder.But excessive when factory building span, or article hoisting position while not allowing to advance cart on locus, needs lifting trolley to cross rail article hoisting.The patent No. that Patent Office of the People's Republic of China is authorized is 200520028002.8, patent name is crane cross track locking device, this device is packed on the girder of hoisting crane, the hinged middle brace rod in end in the be inserted into fixed beam fixed cover being fixedly mounted with on the side of girder, one end of this hinged wedge shape movable block in middle brace rod one end, this wedge shape movable block by the driving that is packed in the rotating shaft on girder to realize the swing at its two ends.This is crossed rail blocking device and adopts rotating shaft to drive the form of wedge shape movable block, and the rail blocking device of crossing of this pattern exists the shortcomings such as locking is not firm, and positioning precision is low.
Summary of the invention:
Task of the present utility model is that a kind of tracking of proposition is accurate, and the simple to operate and good crane in bridge type of safety performance is crossed rail blocking device.
Task of the present utility model completes like this, crane in bridge type is crossed rail blocking device, it comprises main car owner's beam and secondary car owner beam, it is characterized in that: on main car owner's beam, motor and retarder are installed, on the output shaft of retarder, miniature gears is housed, miniature gears is to fix by the axle of girder top flange plate, big gear wheel is fixed with miniature gears engagement and is rotated by the axle of girder top flange plate, in big gear wheel, be equipped with locating plate, connecting rod is arranged on main car owner's web, baffle plate is hinged on connecting rod, on secondary car owner web, be hinged with secondary vehicle baffle board, on secondary car owner beam, have positioning groove.Linearly, it is circular-arc that upper end is in the lower end of described baffle plate.
The utlity model has following effect: the utility model adopts motor driving, quadric linkage to realize the cross rail of crane in bridge type lifting trolley on major-minor car owner beam and moves, utilize locating plate to lock spacing simultaneously, compact conformation, simple to operate, accurate positioning, the life-span is long, performance safety is reliable.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model; Fig. 2 is the side diagram of Fig. 1; Fig. 3 is that OTC's trolley is crossed the constitution diagram before rail; Fig. 4 is the constitution diagram that OTC's trolley is crossed rail.
Drawing explanation: 1, reductor, 2, miniature gears, 3, main car owner's beam, 4, connecting rod, 5, main vehicle baffle board, 6, secondary vehicle baffle board, 7, locating plate, 8, big gear wheel, 9, positioning groove, 10, secondary car owner beam, 11, motor.
The specific embodiment:
In conjunction with above accompanying drawing, describe embodiment in detail, as shown in Figure 1, motor 11 and retarder 1 are installed on main car owner's beam 3, miniature gears 2 is housed on the output shaft of retarder 1, miniature gears is to fix by the axle of girder top flange plate, big gear wheel is fixed with miniature gears engagement and is rotated by the axle of girder top flange plate, in big gear wheel, be equipped with locating plate 7, connecting rod 4 is arranged on main car owner's beam 3 webs, baffle plate 5 is hinged on connecting rod 4, on secondary car owner beam 10 webs, be hinged with secondary vehicle baffle board 6, on secondary car owner beam, have positioning groove 9, the lower end of described baffle plate 5 linearly, it is circular-arc that upper end is, the straight line portion of lower end is to prevent that lifting trolley from dropping, the circular-arc of upper end is that circular arc portion can drive baffle plate 6 to rotate when rotating.
It is as follows that crane in bridge type is crossed rail blocking device working process: when hoisting crane need to be crossed rail, electrical motor 11 drives retarder 1 to rotate, the miniature gears being arranged on reducer output shaft rotates counterclockwise, drive big gear wheel 8 to clockwise rotate, the locating plate 7 being cemented in big gear wheel turns in the positioning groove 9 of secondary car owner beam, realizes the accurate tracking of major-minor car location.Simultaneously, big gear wheel 7 drives hinged connecting rod 4 thereon upwards to rotate, connecting rod 4 drives main vehicle baffle board 5 to clockwise rotate, main vehicle baffle board 5 drives secondary vehicle baffle board 6 to rotate counterclockwise, now major-minor vehicle baffle board all turns to girder top, lifting trolley runs to secondary car owner beam from main car owner's beam, realizes smoothly rail.After crossing rail and finishing, motor reversal, drives major-minor vehicle baffle board to turn to major-minor car owner beam below, prevents that lifting trolley from running to end of main beam and falling down.
It is spacing that the utility model adopts positioning element to lock, and utilize motor-driven quadric linkage to realize lifting trolley simultaneously and cross rail operation, not only compact conformation, simple to operate, and accurate positioning, safety performance is good.
