Specific embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book is understood other advantages and efficacy of the present invention easily.
It should be clear that this specification structure depicted in this specification institute accompanying drawings, ratio, size etc., only to cooperate specification to be taken off
The content shown is not intended to limit the invention enforceable qualifications so that those skilled in the art understands and reads, therefore
Do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influencing the present invention
Under the effect of can be generated and the purpose that can reach, the range that disclosed technology contents can be covered should all be still fallen in
It is interior.Meanwhile in this specification cited such as "upper", "lower", "left", "right", " centre " term, be merely convenient to describe
Be illustrated, rather than to limit the scope of the invention, relativeness is altered or modified, and is changing technology without essence
It inside holds, when being also considered as the enforceable scope of the present invention.
Dumper includes vehicle frame and compartment in the prior art, and the position of close rear end is hinged on the vehicle frame on the compartment
On, hydraulic jacking device is installed on vehicle frame, pushes compartment to tumble backward by the piston rod of hydraulic cylinder.
As shown in Figures 1 to 4, the present invention provides a kind of dumper pintle locking device based on wirerope, including fixation
Seat 1, wirerope 2 and latch hook 3, the fixing seat 1 are fixed on the vehicle frame, and the latch hook 3 includes ontology and hook portion 31, described
Ontology is equipped with the first connecting hole 32 and the second connecting hole 33, and first connecting hole 32 is hinged on described by fixing axle 321
The bottom in compartment, the second connecting hole 33 is interior equipped with the first pin shaft 331, and one end of the wirerope 2 is hinged in fixing seat 1, separately
One end is connected on the first pin shaft 331.
