Description
Technical field
The utility model belongs to forestry machine field, more particularly to a kind of timber on woodland lumber carrier
Gripping apparatus.
Background technology
Log Grapple, it is a kind of hydraulic clamp for being used to capture timber on skidder, wherein, alternating expression is grabbed
Tool is a kind of relatively common type.Two clamping jaws up and down on alternating expression gripping apparatus mutually stagger in clamping process, by changing
Clamping range can be expanded by becoming hydraulic cylinder travel, obtain different armful circular diameters.According to upper gripper jaw structure type, alternating expression gripping apparatus
Two kinds of split and monoblock type can be divided into again.Two monodactyles of split upper gripper jaw are controlled respectively by two hydraulic cylinders, and whole
Body formula structure is compared, and is the advantages of this upper gripper jaw structure：Two monodactyles of upper gripper jaw can distinguish wood clamped by accurately adaptation
External diameter at material, so as to avoid because on timber length direction thickness it is uneven and to the grip strength of gripping apparatus caused by bad shadow
Ring.However, increasing due to hydraulic cylinder quantity, the manufacturing cost and maintenance cost of the upper gripper jaw structure of split are higher,
Required supporting hydraulic control architectures are also more complicated.
The content of the invention
The utility model provides a kind of Log Grapple on woodland lumber carrier, it is therefore intended that：By to existing
Log Grapple in the structure of monoblock type upper gripper jaw optimize so that monoblock type upper gripper jaw has concurrently and pressed from both sides on existing split
The clamping performance advantage of pawl and the monoblock type upper gripper jaw cost advantage of itself.
The technical problem that the utility model solves is realized using following technical scheme：The utility model provides a kind of use
Log Grapple on woodland lumber carrier, including upper gripper jaw and lower clamping jaw, upper and lower two clamping jaws pass through main be hinged point articulated
It is connected, a hydraulic cylinder is connected between upper and lower two clamping jaws, the both ends of hydraulic cylinder are hinged and connected with upper and lower two clamping jaws respectively,
By controlling the action of hydraulic cylinder to realize the folding pinching action of gripping apparatus, triangular structure is projected as under described upper gripper jaw,
Two monodactyles in left and right are provided with described lower clamping jaw, two monodactyles are fixedly connected in the agent structure of lower clamping jaw, in gripping apparatus
Lower perspective plane in, between two monodactyles of the projection of upper gripper jaw on the lower clamping jaw, be hinged with the downside of described upper gripper jaw
Arc vice jaw, arc vice jaw share two, are respectively hinged at the downside of the triangular structure of upper gripper jaw.
Preferably, sphere salient point is provided with the inside of described arc vice jaw.
The beneficial effects of the utility model are：
1st, the utility model on upper gripper jaw by setting arc vice jaw so that upper gripper jaw can accurately adapt to the outer of bundle of wood
Portion's shape, so as to realize the clamping effect equal with split upper gripper jaw, realize to the monoblock type in existing Log Grapple
The optimization of the structure of upper gripper jaw so that monoblock type upper gripper jaw has the clamping performance advantage and entirety of existing split upper gripper jaw concurrently
The formula upper gripper jaw cost advantage of itself.
2nd, the utility model is provided with the salient point of sphere in the inner side of arc vice jaw, can be effectively increased arc vice jaw and timber
Between frictional force, further improve clamping effect.Salient point is shaped to sphere rather than sharp face, can effectively avoid pressing from both sides
Pawl causes to damage to timber.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the partial enlarged drawing at A in Fig. 1；
Fig. 3 be in Fig. 1 B to direction view.
In figure：1- upper gripper jaws, 2- hydraulic cylinders, clamping jaw under 3-, 4- monodactyles, 5- arc vice jaws, 6- salient points, the main pin joints of 7-.
Embodiment
The utility model is described further below in conjunction with accompanying drawing：
The present embodiment includes upper gripper jaw 1 and lower clamping jaw 3, and upper and lower two clamping jaws are hinged and connected by main pin joint 7, and upper and lower two
A hydraulic cylinder 2 is connected between individual clamping jaw, the both ends of hydraulic cylinder 2 are hinged and connected with upper and lower two clamping jaws respectively, pass through control
The folding pinching action of gripping apparatus is realized in the action of hydraulic cylinder 2.It is above universal architecture of the prior art, will not be repeated here.
Triangular structure is projected as under described upper gripper jaw 1, compared with prior art, the upper gripper jaw 1 of triangular structure
With higher structural strength.
Two monodactyles 4 in left and right are provided with described lower clamping jaw 3, two monodactyles 4 are fixedly connected on the body junction of lower clamping jaw 3
On structure, in the lower perspective plane of gripping apparatus, the projection of upper gripper jaw 1 is located between two monodactyles 4 on lower clamping jaw 3, on being formed
Situation staggeredly down.
The downside of described upper gripper jaw 1 is hinged with arc vice jaw 5, and arc vice jaw 5 shares two, is respectively hinged at upper gripper jaw
The downside of 1 triangular structure.By setting arc vice jaw 5 on upper gripper jaw 1 so that upper gripper jaw 1 can accurately adapt to bundle of wood
Outer shape, so as to realize the clamping effect equal with split upper gripper jaw, realize to whole in existing Log Grapple
The optimization of the structure of body formula upper gripper jaw so that monoblock type upper gripper jaw have concurrently existing split upper gripper jaw clamping performance advantage and
The monoblock type upper gripper jaw cost advantage of itself.
The salient point 6 of sphere is provided with the inner side of arc vice jaw 5, rubbing between arc vice jaw 5 and timber can be effectively increased
Power is wiped, further improves clamping effect.Salient point 6 is shaped to sphere rather than sharp face, can effectively avoid clamping jaw to wood
Material causes to damage.
