Falling, serious causes the accident, and as smashed equipment, injury to personnel etc., this still awaits technology solution
Certainly.
Summary of the invention
In order to solve the problems referred to above, this utility model provides a kind of excavator self-locking grab bucket.
The technical solution adopted in the utility model is: a kind of excavator self-locking grab bucket, its feature exists
In including left grab bucket and right grab bucket, left grab bucket and right grab bucket upper end are hinged on one by jointed shaft
Rising, jointed shaft connects has the landing arm stretched upwards, between landing arm and left grab bucket, landing arm
And it is respectively equipped with folding hydraulic cylinder between right grab bucket, in left grab bucket, is provided with one and hinge near superjacent air space
The rotary shaft that spindle is parallel, rotating shaft terminal runs through left grab bucket two ends sidewall and distinguishes outside sidewall
Being fixedly connected with locking swing arm, locking swing arm free end is provided with latch hook, and right grab bucket two ends are provided with lock
The locking that hook coordinates is protruding, is fixedly connected with the driving passed outside left grab bucket in the middle part of rotary shaft
Arm, is provided with capstan winch in the side in left grab bucket external drive arm swing direction, and opposite side is provided with commutation
Pulley, capstan winch is wound with a driving rope, drives rope one end to be connected to drive arm external end head, drives
Running rope one end is walked around angle pulley and is connected to drive arm external end head, and capstan winch drives locking swing arm reciprocal
Swing, swing process drives rope do not leave being a little fixed on capstan winch in capstan winch part, strand
Dish connects driving motor.
Further, described locking swing arm is provided with two in the position of free termination and close termination
Latch hook, right grab bucket two ends are provided with the locking projection that latch hook coordinates.
Further, described driving motor connects has controller, left grab bucket or right grab bucket to be provided with
Closed sensor, sensor is connected with controller.
This utility model use time, left and right grab bucket by hydraulic pressure close after capstan winch by drive rope,
Driving arm, rotary shaft to drive locking swing arm to rotate makes latch hook catch on locking projection, it is achieved left and right
The reliable Guan Bi of grab bucket, even if now hydraulic failure does not results in spilling of grab bucket yet, when opening
Before hydraulic-driven, capstan winch is again by driving rope, driving arm, rotary shaft to drive locking swing arm to rotate
Release the latch hook locking to locking projection, both can discharge the earthwork, safe and reliable.

Detailed description of the invention
As shown in Figure 1, 2, this excavator self-locking grab bucket is provided with a left side and grabs this utility model embodiment
Bucket 1 and right grab bucket 2, left grab bucket and right grab bucket upper end are hinged by jointed shaft 3, hinge
Connecting in spindle and have the landing arm 4 stretched upwards, between landing arm and left grab bucket, landing arm is with right
It is respectively equipped with folding hydraulic cylinder 5 between grab bucket, in left grab bucket, is provided with one with hinged near superjacent air space
The rotary shaft 6 that axle is parallel, rotating shaft terminal runs through left grab bucket two ends sidewall and distinguishes outside sidewall
Being fixedly connected with locking swing arm 7, locking swing arm free end is provided with latch hook 8, and right grab bucket two ends set
There is the locking projection 9 coordinated with latch hook, be fixedly connected with in the middle part of rotary shaft and pass outside left grab bucket
The driving arm 10 in portion, is provided with capstan winch 11 in the side in left grab bucket external drive arm swing direction,
Opposite side is provided with angle pulley 12, and capstan winch is wound with a driving rope, drives rope one end to connect
Driving arm external end head, driving rope one end to walk around angle pulley and be connected to drive arm external end head, strand
Locking swing arm reciprocally swinging is moved in dribbling, drives rope not leave in capstan winch part in swing process
Point is fixed on capstan winch, and capstan winch connects driving motor 13, and driving motor to connect has controller,
Left grab bucket or right grab bucket are provided with closed sensor, and sensor is connected with controller.
This utility model use time, left and right grab bucket by hydraulic pressure close after capstan winch by drive rope,
Driving arm, rotary shaft to drive locking swing arm to rotate makes latch hook catch on locking projection, it is achieved left and right
The reliable Guan Bi of grab bucket, even if now hydraulic failure does not results in spilling of grab bucket yet, when opening
Before hydraulic-driven, capstan winch is again by driving rope, driving arm, rotary shaft to drive locking swing arm to rotate
Release the latch hook locking to locking projection, both can discharge the earthwork, safe and reliable.
When this utility model is implemented, can set in the position of the free termination of locking swing arm and close termination
There are two latch hooks, right grab bucket two ends to be provided with the locking projection that latch hook coordinates, improve the reliable of indication
Property.
It is only the specific embodiment of the invention in sum, but is not limited to embodiment, also can be each
Technical characteristic reconfigures more implementation, all without departing from the inventive concept,
The equivalence done according to the application is modified and prior art interpolation is accordingly to be regarded as the technology of the present invention category.
