Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing, to the present invention into
One step is described in detail.Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts all
Other embodiments shall fall within the protection scope of the present invention.
As shown in Figure 1 to 4, a kind of equalizer bar locking device of slag-soil truck container, including equalizer bar 1, be located at equalizer bar 1
The front beam 2 of top；It is characterized by: the end of the equalizer bar 1 is provided with latch hook 4, one end of latch hook 4 is hinged on equalizer bar
On 1, the other end has gib head 13, has card access surface 16 on the gib head 13, and card access surface 16 is arc surface, the circular arc of card access surface 16
Center is the hinge joint 10 of latch hook 4；The end of the front beam 2 is fixed with lock 7, and the upper end of the lock 7 is positioning surface 17；
The gib head 13 catches on lock 7, and positioning surface 17 matches with card access surface 16.
After latch hook 4 rotates, gib head 13 catches on lock 7, and card access surface 16 is stuck on positioning surface 17, completes locking, and positioning surface
17 and card access surface 16 are arc surface, and by rotation, card access surface 16 can be smoothly bonded with positioning surface 17, without there are rotations
Gap, so that substantially reducing the gap between card access surface 16 and positioning surface 17 after locking, it is firm to lock, and mitigates and shakes, and improves
The overall stability of slag-soil truck 18, avoids the building materials in slag-soil truck 18 from damaging or even fall because of shaking.
In the present embodiment, for the ease of processing, it is fixed with lock hook seat 3 in the end of equalizer bar 1, latch hook 4 passes through hinge
It is connected on lock hook seat 3, passes through welded connecting between equalizer bar 1 and lock hook seat 3.
2 upper end of front beam is fixed with container 8, lock 7 by being welded to connect on front beam 2, and front beam 2 be resisted against it is flat
The upper end of balance beam 1, when needing to unload, front beam 2 and equalizer bar 1 are detached from.
Cylinder 5 is fixed on the equalizer bar 1, the piston rod of cylinder 5 is connected with push rod 6；Cunning is offered on the latch hook 4
Slot 14, sliding slot 14 extend between gib head 13 and lock hook seat 3, and along the length direction of latch hook 4；Sliding in the sliding slot 14
It is provided with slide bar 15, slide bar 15 is fixed on the free end of push rod 6.Cylinder 5 pushes latch hook 4 to rotate, and realizes and unlocks, at 4 turns of latch hook
During dynamic, the tie point between push rod 6 and latch hook 4 can generate variation, and the present embodiment uses 15 structure of sliding slot 14 and slide bar,
So that latch hook 4 is during rotation, slide bar 15 is free to slide in sliding slot 14, and cylinder 5 can smoothly push latch hook 4 to rotate.
In the present embodiment, single-acting cylinder can be used in cylinder 5, and single-acting cylinder is common one of cylinder, is divided into bullet
Spring resets and external force resets, and single-acting spring reset cylinder is used in the present embodiment, single-acting spring reset cylinder is mainly by living
The composition such as plug, cylinder barrel, front and rear cover, piston rod, spring, pull rod, sealing ring, 5 one end of cylinder is by compressed air-driven, the other end
It is communicated with the atmosphere, resets and driven by spring.
In order to guarantee that latch hook 4 will not be automatically-unhooked under external force or effect of inertia, can connect between equalizer bar 1 and latch hook 4
Tension spring 9 is connect, one end of tension spring 9 is fixed on equalizer bar 1, and the other end is fixed on the middle part of latch hook 4, and tension spring 9 is always in stretching
State, after latch hook 4 is rotated clockwise and broken off relations, tension spring 9 pulls latch hook 4 to reset, after latch hook 4 hooks lock 7, tension spring 9
Pulling force plays fastening effect, prevents latch hook 4 from breaking off relations under external force or effect of inertia, improves the locking stability of equalizer bar 1, lock
It is tight more firm.Certainly, it can also be used simultaneously with single-acting spring reset cylinder 5, the spring in tension spring 9 and cylinder 5 acts on
Under, it is more firm to lock.
13 end of gib head of the latch hook 4 has the first inclined-plane 11, and the lower end of lock 7 has the second inclined-plane 12, and first tiltedly
Face 11 matches with the second inclined-plane 12.And first the tilt angle on inclined-plane 11 and the second inclined-plane 12 be 30 °~60 °, the first inclined-plane
11 are arranged in parallel with the second inclined-plane 12, and with further, the tilt angle on first inclined-plane 11 and the second inclined-plane 12 is
45 °, and the low spot on above-mentioned two inclined-plane is close to one end of front beam 2.In locking, front beam 2 drives lock 7 to act downward,
Second inclined-plane 12 is pressed on the first inclined-plane 11, and under the wedging power effect on inclined-plane, latch hook 4 is rotated clockwise, and latch hook 4 is opened,
It then proceedes to act downward, front beam 2 can playback, and then latch hook 4 rotates counterclockwise, and locking can be completed, it can be achieved that automatic
Locking, easy to operate, structure is simple.
The equal rounded corner in end of the card access surface 16 and positioning surface 17 plays guiding role, guarantees that latch hook 4 can be hooked smoothly
Lock 7.
The course of work of the invention is as follows:
When slag-soil truck 18 needs to unload, the piston rod of control cylinder 5 stretches out, and band moveable lock hook 44 is around 10 up time of hinge joint
Needle rotation, gib head 13 are detached from lock 7, and then front beam 2, lock 7 and 8 unilateral side of container move up, and complete unloading, while cylinder
5 automatically reset under the action of the spring, and piston rod retracts, and under the pulling force effect of tension spring 9, latch hook 4 automatically resets, and works as unloading
After the completion, front beam 2, lock 7 and container 8 move down, and latch hook 4 is under the wedge action on the first inclined-plane 11 and the second inclined-plane 12
It rotates clockwise, completes to reset so that 8 front beam 2 of container, lock 7 and container 8 continue to fall, then latch hook 4 is in 9 He of tension spring
Automatically rotation counterclockwise is done under the spring effect of cylinder 5, and clasp joint completes locking at the top of lock 7.
Therefore, the structure that the present embodiment uses is very simple, and locking speed is fast, under the action of tension spring 9, locks more firm
It leans on, effectively prevents lock-off, machine automatization locking can be achieved in when locking under the action of inclined-plane and tension spring 9, and it is easy to operate, reliably
Property it is high.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, there can be various modifications and variations in the spirit and principles in the present invention, these equivalent variation or replacement etc.,
It is all included in the scope of protection of the present invention.
