Abstract
The invention discloses a bridge crane off-track locking device which comprises a main-vehicle girder and an auxiliary-vehicle girder, wherein a motor and a speed reducer are installed on the main-vehicle girder, and a small gear is arranged on an output shaft of the speed reducer; the small gear is fixed through a mandrel of a girder top flange plate, and a big gear is fixed through the mandrel of the girder top flange plate and is engaged with the small gear to rotate; a positioning plate is arranged on the big gear, and a connecting rod is installed on a main-vehicle girder web; a baffle plate is hinged onto the connecting rod, and an auxiliary-vehicle baffle plate is hinged onto an auxiliary-vehicle girder web; a positioning groove is formed in the auxiliary-vehicle girder. The lower end of the baffle plate is linear, and the upper end of the baffle plate is arc-shaped. The bridge crane off-track locking device adopts motor driving and a crank and rocker mechanism to realize the off-track running of a bridge-crane lifting car on the main-vehicle girder and the auxiliary-vehicle girder and meanwhile utilizes the positioning plate for locking and limiting. The bridge crane off-track locking device has the advantages of compact structure, simplicity in operation, positioning accuracy, long service life and safe and reliable performance.
Description
Technical field:
The present invention relates to a kind of rail blocking device of crossing, be 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 vertically operation on girder.But excessive when the factory building span, or the article hoisting position is not while allowing to advance cart on locus, need lifting trolley to cross the 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 be fixedly mounted with on the side of girder, one end of the hinged wedge shape movable block of this 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.The shortcomings such as this crosses the form that the rail blocking device adopts rotating shaft driving wedge shape movable block, and the rail blocking device of crossing of this pattern exists locking not firm, and positioning precision is low.
Summary of the invention:
Task of the present invention 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 the rail blocking device.
Task of the present invention completes like this, crane in bridge type is crossed the 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 rotated with the miniature gears engagement by the axle of girder top flange plate is fixing, on 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 present invention has following effect: the present invention adopts motor driving, quadric linkage to realize that the cross rail of crane in bridge type lifting trolley on major-minor car owner beam moves, utilize simultaneously locating plate to lock spacing, compact conformation, simple to operate, accurate positioning, the life-span is long, performance safety is reliable.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present invention; Fig. 2 is the side diagram of Fig. 1; Fig. 3 is the constitution diagram before OTC's trolley is crossed 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 rotated with the miniature gears engagement by the axle of girder top flange plate is fixing, on 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 rotations when rotating.
It is as follows that crane in bridge type is crossed rail blocking device working process: when hoisting crane needed rail, electrical motor 11 drives retarder 1 and rotates, the miniature gears be arranged on reducer output shaft rotates counterclockwise, driving big gear wheel 8 clockwise rotates, the locating plate 7 be cemented on 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 and upwards rotates, connecting rod 4 drives main vehicle baffle board 5 and clockwise rotates, main vehicle baffle board 5 drives secondary vehicle baffle board 6 and rotates counterclockwise, now the major-minor vehicle baffle board all turns to the girder top, lifting trolley runs to secondary car owner beam from main car owner's beam, realizes smoothly rail.After crossing the rail end, motor reversal, drive the major-minor vehicle baffle board and 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 present invention adopts positioning element to lock, and utilizes simultaneously motor-driven quadric linkage to realize that lifting trolley crosses rail operation, not only compact conformation, simple to operate, and accurate positioning, and safety performance is good.
