Description

The locking device that railway container flat car loading is used

Technical field

The locking device that railway container flat car loading is used relates to a kind of container locking device that is assemblied on the articulated car, especially convertible full automaticity container locking device.

Background technology

The straight desk-top or projective table type container locks of the many employings of China Railway freight container at present, 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 freight container is not retrained, there is potential safety hazard.Freight container may take place when operation conditions is abominable turn over accident.The patent No. 20062013384.9 discloses a kind of " the automobile-used upset locking device of railway container ", it is to level up on the plate at lock reversing the lock solid welding, the lock rotating shaft is welded with the bottom surface that lock is leveled up plate, and the lock rotating shaft is inserted between the axis hole of back and front supporting plate, and the back and front supporting plate welds with the car body crossbeam respectively.This locking device is owing to adopt the assembly welding structure, and parts are more, and complex structure is installed difficulty.Level up on the plate at lock owing to reverse the lock solid welding, the lock rotating shaft is welded on the bottom surface that lock is leveled up plate again, reverses lock the vertical bearing capacity and the longitudinal impact force of freight container is transmitted on the back and front supporting plate, and whole like this locking device is also insecure.And the locking device of this structure is also insecure to the constraint of twistlock, has potential safety hazard.

Summary of the invention

The problem to be solved in the present invention is exactly to provide a kind of structure more simple, reasonable, firm at above deficiency, the convertible locking device of can be in the horizontal direction casing with vertical while constraint set.The employing technical scheme is as follows:

It comprises revolves lock, tapered end rotating shaft and baffle plate, and its gordian technique is:

Described locking device revolves the lock base in addition, has dovetail furrow revolving the lock base top surface, has a through hole on the base revolving lock;

Described locking device also has lock, and the lock middle part is a cavity, has chute in the inboard of lock both sides;

Has a dovetail form boss revolving lock bottom, the dovetail form boss embeds in the dovetail furrow that revolves on the lock base, the tapered end rotating shaft is inserted in the through hole that revolves on the lock base, and tapered end rotating shaft two ends lay respectively in the chute of lock both sides, by the baffle plate rotating shaft baffle plate is installed at the lock other end.

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, revolves lock and adopts full-automatic spin lock, and revolves the lock base and is connected by dovetail furrow, and the through hole that revolves on the lock base is inserted in the lock rotating shaft, and with revolve the spot welding of lock base, it is simple, firmly to revolve locking bit, freight container latch facility, safety.

3, lock rotating shaft two ends are positioned at the chute of lock, revolve the lock base and are positioned at lock, and lock is welded on the floor underframe for vehicle, has so more increased the fastness of whole locking device, is beneficial to traffic safety.When the working position of locking device, revolve lock on vertical and revolved the lock base and retrain with dovetail furrow, to revolve the lock base and retrained by lock again, horizontal direction is revolved lock like this and is retrained fully by the side of lock and baffle plate constraint, and freight container is as safe as a house.

4, the push-and-pull upset of lock rotating shaft except being used to lock also because of locking rotating shaft and revolving the spot welding of lock base, revolved lock if will take out, and the rotating shaft of necessary destruction lock does not have special tool to accomplish, so this locking device has very strong anti-theft feature.

5, simple in structure, but revolve all once-formings of lock base and lock, processing technology is simple, installs and uses, dismounting, easy to maintenance, and safe and reliable, greatly degree reduces fault rate.

6, 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.Container handling efficient height, and full-automatic spin lock has enough vertical constrained forces to freight container, can prevent effectively that freight container from turning over, and safety is good.When full-automatic spin lock is not worked, tapered end can be turned to the below, effectively lock is revolved in protection, has improved the service life of whole locking device.

The specific embodiment

Referring to accompanying drawing, the present invention includes full-automatic spin lock 6, tapered end rotating shaft 3 and baffle plate 4, its gordian technique is:

Described locking device revolves lock base 7 in addition, has dovetail furrow 11 revolving lock base 7 end faces, revolve be positioned on the lock base 7 dovetail furrow below have a through hole;

Described locking device also has lock 2, and lock 2 middle parts are a cavity, has chute 1 in the inboard of lock 2 both sides;

Has a dovetail form boss 12 in full-automatic spin lock 6 bottoms, dovetail form boss 12 embeds in the dovetail furrow 11, tapered end rotating shaft 3 is inserted in the through hole that revolves lock base 7, tapered end rotating shaft 3 with revolve 7 spot welding of lock base and fix, tapered end rotating shaft 3 two ends lay respectively in the chute 1 of lock 2 both sides, by baffle plate rotating shaft 5 baffle plate 4 are installed at lock 2 other ends.

Earlier lock 2 is welded on the flatcar underframe during use, full-automatic spin lock 6 by dovetail furrow 11 with revolve the lock base 7 cooperate, constitute and revolve the lock assembling, it is spacing with retaining to revolve lock base 7 two ends, wherein an end adopts active catch 9, with screw 10 with active catch 9 with revolve lock base 7 tight, and screw 10 is locked base 7 spot welding with revolving, the other end is a fixed stop 8, fixed stop 8 with revolve lock base 7 weld togethers.Tapered end rotating shaft 3 is passed and is revolved the hole of lock on the base 7 and insert in the chute 1 of lock 2 inboards, will revolve the lock assembling and be assembled into lock 2, and with tapered end rotating shaft 3 with revolve 7 solid weldings of lock base.Baffle plate 4 usefulness baffle plate rotating shafts 5 and lock 2 assemblings, and with baffle plate rotating shaft 5 and baffle plate 4 solid weldings.

It shown in Fig. 1 the working position of this locking device.When this locking device is in working position and full-automatic spin lock and is in the tram, get final product normal operation.Owing to adopt full-automatic spin lock, therefore do not need manual operation, during loading container, revolve lock meeting auto lock, during unload containers, revolving lock can self-opening.

When this locking device is not worked, can will revolve the lock upset by Fig. 6-step shown in Figure 9:

1. baffle plate 4 is started, promote full-automatic spin lock to the baffle plate direction and be assembled into the appropriate location;

2. be the assembling of fulcrum rotation full-automatic spin lock with tapered end rotating shaft 3;

3. up to revolving lock vertically downward;

4. promote the full-automatic spin lock assembling to reversing sense and get back to original position, put down baffle plate 4.

When this locking device needs work, can locking device be returned to working position with reference to said method.
