The hanger realizes automatic opening and closing of heavy hoisting equipment through the limiting mechanism, and is convenient and safe to operate; the limiting mechanism is compact and stable in structure; through a guide post of the hanger, the hanger is more convenient and accurate and higher in efficiency in heavy hoisting; and by designing a connecting lug plate, the accuracy of the in-place space of the hanger is further realized, and meanwhile, the connecting lug plate is used as a supporting piece for the lever mechanism so that the hanger has more scientific structure, better functions and skilful multi-purpose effect.
Description
Technical field
The invention belongs to machine design and make the field, require to belong to heavy lifting equipment and manufacture and design the field, particularly a kind of railway truck central sill hoisting appliance.
Background technology
Domestic each railway truck manufacturer used central sill suspender in central sill handling operation generally adopts the gravity self-locking structure at present.When opening hooking part, suspender drops to the hook arm and contacts with middle flange of beam, and the operator opens out the lifting of hook auxiliary member, and the central sill suspender closes hook by suspension hook gravity and carries out handling; When driving hook and falling part, suspender drops to the hook arm and contacts with middle flange of beam, leans on suspender gravity to drive hook automatically, is opening the hook position, and the operator is closed make and break hook auxiliary member and will be opened hook-shaped attitude and keep, and withdraws the central sill suspender.Utilizing this mode to lift by crane can be long because of suspender suspension hook and lorry central sill Heave Here distance, and suspension hook and lorry central sill side friction cause the central sill rust proofing primer to be destroyed, even central sill can take place by scratch, the situation of beam strength appearance in the destruction; When workpiece breaks off relations, need the operator that application force is provided, the guiding suspender breaks away from workpiece, and suspension hook is prone to flange of beam in the hook lorry during unhook, and safety misadventure takes place.
Summary of the invention
The present invention discloses a kind of novel railway lorry central sill suspender according to the deficiency of prior art; The problem that the present invention will solve provides a kind of convenient railway truck central sill suspender that opens and closes of realizing; It is accurately convenient that the present invention has realized that also the suspender suspension member is gone into the position; Shortened suspender and gone into the moving distance of displacement, reduced damage hanging piece.
The present invention realizes through following technical scheme:
Novel railway lorry central sill suspender comprises supporting seat, girder and suspension hook, and wherein: be fixedly connected on the stop gear on the supporting seat in addition, girder moves in the position-limited trough of stop gear; Suspension hook is installed on the supporting seat through leverage, and an end of suspension hook is connected with removable girder through leverage to be realized opening and closing.
The position-limited trough of further said stop gear is the bar shaped groove and constitutes suspension hook by the locating dowel pin that passes the bar shaped groove and open and close shelves.
Further said stop gear is formed position-limited trough by the base and the limiting block of bar shaped hollow; Telescopic locating dowel pin is through spring, sleeve and handle and be screwed in the stop gear base wall.
Above-mentioned leverage comprises " L " shape suspension hook, and " L " shape suspension hook arm and supporting seat are hinged, and an end of " L " shape suspension hook and the gangbar of removable girder are hinged.
Above-mentioned girder comprises gangbar, end carriage, connecting panel, central sill, hanger and the fixing screw of gangbar; Gangbar one end is connected with end carriage, and connecting panel is connected with central sill with end carriage to be fixed, and connecting panel moves in position-limited trough.
Above-mentioned supporting seat comprises support beam, backing plate, connection otic placode and guidepost; It is fixing and hinged through fulcrum post with suspension hook to connect the welding of otic placode and support beam, and guidepost is weldingly fixed on the support beam both sides.
Hang the loser place of hanger on the girder during use with the elevator machinery main hook, suspender is moved to lorry central sill center of gravity place, slowly fall suspender to suspender supporting seat and contact with the central sill top flange; Handle in the operating spring limit switch mechanism withdraws from locating dowel pin from base and cooperates the position-limited trough that forms with limiting block, keeps action; The elevator machinery main hook hangs girder and slowly rises; This moment, supporting seat kept original position, and the interlock screw rod on the girder drives suspension hook around the fulcrum post rotation, begins to close the hook action; When girder rises to when contacting with limiting block, the handle in the shut-down operation spring limit switch mechanism, suspension hook stop the rotation and hold mode, realize closing the hook action; This continued rising elevator machinery main hook, supporting seat rises thereupon, and the railway truck central sill keeps original position, and supporting seat rises to suspension hook and contacts with the railway truck central sill; Continued rising elevator machinery main hook again, the railway truck central sill will be by handling.When falling part, the railway truck central sill is put into the appointment station, the support beam in decline suspender to the suspender supporting seat contacts with railway truck central sill top flange; Girder slowly descends; This moment, supporting seat kept original position, and the interlock screw rod on the girder drives suspension hook around the fulcrum post rotation, begins out the hook action; When plane on the girder was lower than the locating dowel pin lower plane in the spring limit switch mechanism, locating dowel pin received the tension force effect of spring, is retracted into spacing space, kept suspender to open hook-shaped attitude, hung suspender.Limiting block in guidepost on the suspender supporting seat and the spring limit switch mechanism; In the handling process, shorten suspender and gone into the moving distance of displacement; Protected the railway truck central sill not receive the suspension hook scratch; Because the design of guidepost is arranged, not only avoided potential safety hazard, and the storage support frame is provided for suspender.
In sum, helpfulness of the present invention is: suspender of the present invention has been realized the automatic shutter of heavy handling appliance through stop gear, and easy and safe to operate; Stop gear is simple for structure stable; The guidepost setting of suspender makes heavy handling more convenient accurately, and efficient is higher; The design that connects otic placode had both realized further that suspender went into the accuracy of bit space, and simultaneously again as the strut member of leverage, structure is science more, and function is more excellent, has high-mobility, multipurpose, wheeled vehicle effect cleverly.The present invention be a kind of simple in structure, easy to use, practicality is good, the process-cycle reaches railway truck central sill suspender easy to maintenance soon.
