Abstract
The invention discloses a locking device of a shipping container of a rail flat car, and relates to a locking device of a shipping container which is assembled on a rail flat car, in particular to a fully automatic stationary-typed locking device of a shipping container. The invention comprises a fully automatic spin lock, a spin lock base and a lock seat, the top surface of the spin lock base is opened with a dovetail groove, and the two bottom sides of the spin lock base have steps; the two sides and one end of the lock seat have frames, and the frames along the two sides of the lock seat are provided with convex platforms; the bottom of the fully automatic spin lock has a dovetail-shaped convex platform, which is embedded into the dovetail groove, and the spin lock base is embedded into the lock seat. The structure of the invention is simpler and more reasonable, and the whole device is firmer and can restrict a shipping container simultaneously along the horizontal and vertical directions.
Description
Technical field
A kind of railway flat car container locking device relates to a kind of container locking device that is assemblied on the articulated car, especially fixed type full automaticity container locking device.
Background technology
At present the China Railway freight container is adopted straight desk-top or projective table type container lock more, and these two kinds do not need manual operation when being locked in loading and unloading container, but because their constraint set vannings in the horizontal direction, and vertical to not constraint of freight container, have potential safety hazard.Freight container may take place when operation conditions is abominable turn over accident.
Summary of the invention
The problem to be solved in the present invention provides more advantages of simple of a kind of structure at above deficiency exactly, and whole device is more firm, can be in the horizontal direction and the locking device of vertical while constraint set vanning.The employing technical scheme is as follows:
It comprises full-automatic spin lock, revolves lock base and lock, and the described lock base top surface that revolves has dovetail furrow, revolves lock base two bottom sides and has step; Described lock both sides and an end have frame, are provided with boss along the frame of lock both sides; Described full-automatic spin lock bottom has a dovetail form boss, and the dovetail form boss embeds in the dovetail furrow, revolves the lock base and embeds in the lock.
Compared with prior art the present invention has following advantage:
1, this locking device has good assembly performance, is easy to and various articulated car assembling.
2, this device has one and revolves the lock base, adopts full-automatic spin lock to lock base and be connected by dovetail furrow with revolving, and freight container is carried out vertical constraint; Be provided with lock and revolve the lock base and cooperates, to lock base spacing to revolving to rely on the frame of lock and stopper, and lock is welded on the floor underframe for vehicle.Locking for freight container and flatcar underframe provides powerful guarantee like this, ensures that freight container can not turn over, and eliminates safe hidden trouble.
But 3, revolve all once-formings of lock base and lock, structure and processing technology are simple, and be safe and reliable, container handling efficient height.Install and use, dismounting, easy to maintenance.
4, this locking device adopts full-automatic spin lock, does not need manual operation, during loading container, revolves lock meeting auto lock, and during unload containers, revolving lock can self-opening.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is Fig. 1 birds-eye view;
Fig. 3 revolves lock and revolves lock base package assembly scheme drawing for of the present invention;
Fig. 4 is Fig. 3 birds-eye view.
The specific embodiment
Referring to accompanying drawing, the present invention includes full-automatic spin lock 6, revolve lock base 7 and lock 2, described lock base 7 end faces that revolve have dovetail furrow 1, revolve lock base 7 two bottom sides and have step 9, install and fix retaining 8 revolving an end that is positioned at dovetail furrow on the lock base 7; Described lock 2 both sides and an end have frame, are respectively equipped with boss 10 along the frame of lock 2 both sides, and boss 10 constitutes T shape platform and hold down groove with frame; Described full-automatic spin lock 6 bottoms have a dovetail form boss 5, dovetail form boss 5 embeds in the dovetail furrow 1, be full-automatic spin lock 6 and revolve lock base 7 and be connected by dovetail furrow 1, revolve lock base 7 and embed in the locks 2, promptly lock 2 with revolve lock base 7 and be connected with hold down groove by the T shape platform of boss 10 with the frame formation.At lock 2 one ends stopper 3 is installed.
Earlier lock 2 is welded on the flatcar underframe during installation, full-automatic spin lock 6 by dovetail furrow 1 with revolve lock base 7 and cooperate, constitute and revolve the lock assembling, it is spacing with fixed stop 8 to revolve lock one end, the other end is in that to revolve the lock assembling spacing by lock 2 after assembling with lock 2.Revolve lock and pack into behind the lock 2, an end that does not have frame on lock 2 passes through fixedly stopper 3 of bolt 4, then with bolt, nut spot welding.The frame of lock 2 sides and boss 10 cooperate with the step 9 that revolves lock base 7 bottoms, and moving of lock assembling vertical direction revolved in restriction, and the frame of the frame of lock 2 ends, stopper 3 and lock 2 sides has limited and revolved moving of lock assembling horizontal direction.
