Description
Technical field
The present invention relates to the log grapple field of loading machine, especially relate to a kind of log grapple.
Background technology
At present, loading machine captures the mode of Timber Transport is realized by common log grapple.Existing log grapple has mechanical, fluid pressure type etc., and mechanical log grapple needs the effect realizing capturing timber by the drive of machinery, and the kinetic energy captured from diesel oil own can, larger to the consumption of resource, and crawl dynamics is undesirable.The log grapple of fluid pressure type needs to realize grasping movement by hydraulic motor and the hydraulic jack being arranged at gripper place, and in order to keep synchronous, prior art is also provided with coaxial bar linkage structure, ensures the uniformity of two gripper actions.But on the one hand, the setting of hydraulic jack adds the weight of log grapple own undoubtedly, and on the other hand, hydraulic jack adds the structural complexity of log grapple equally, adds the difficulty of the synchronous coordination between hydraulic motor simultaneously.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the object of the invention is to propose a kind of log grapple.
Object of the present invention will be achieved by the following technical programs: a kind of log grapple, comprise hydraulic motor and upper connecting base, described upper connecting base comprises symmetrically arranged first upper connecting base and the second upper connecting base, be fixedly connected with between described first upper connecting base with described second upper connecting base, described hydraulic motor is arranged at the inner chamber of described first upper connecting base and described second upper connecting base formation, the technical program also comprises the first coupling bar and the second coupling bar, the free end of described first coupling bar is provided with the first through hole, the free end of described second coupling bar is provided with the second through hole, described hydraulic motor is connected with decelerator, described decelerator connects leading screw connecting rod, described first through hole and described second through hole coaxial sleeve are connected on described leading screw connecting rod, the other end of described first coupling bar is connected with the first gripper, the other end of described second coupling bar is connected with the second gripper.
Preferably, above-mentioned a kind of log grapple: described first coupling bar and described second coupling bar are positioned at lower connecting base, and described lower connecting base is connected with described upper connecting base.
Preferably, above-mentioned a kind of log grapple: described lower connecting base comprises the first lower connecting base and the second lower connecting base, by four rivet interlacement between described first lower connecting base and described second lower connecting base.
Preferably, above-mentioned a kind of log grapple: described four rivets are equally divided into symmetrical two groups, and described first coupling bar and described second coupling bar are each passed through the space between described two groups of rivets.
Preferably, above-mentioned a kind of log grapple: described first through hole and the hole inwall of described second through hole are provided with the screw thread matched with described leading screw connecting rod.
Preferably, above-mentioned a kind of log grapple: described first coupling bar and described second coupling bar respectively at described first gripper and described second gripper hinged.
Outstanding effect of the present invention is: 1) decelerator slows down to hydraulic motor, make capture timber time can be mild work; 2) rotational translation of hydraulic motor can be flexible motion by leading screw connecting rod, for the gripper of log grapple improves the power opened with closed; 3) the first coupling bar is connected with leading screw connecting rod with the free end of the second coupling bar, ensures the synchronism of the first gripper and the second gripper action.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail the specific embodiment of the present invention, is easier to understand, grasp to make technical solution of the present invention.

Detailed description of the invention
As shown in Figure 1, a kind of log grapple of the present embodiment, comprise hydraulic motor 3 and upper connecting base, upper connecting base comprises symmetrically arranged first upper connecting base 1 and the second upper connecting base 2, be fixedly connected with between first upper connecting base 1 with the second upper connecting base 2 and form a cavity, hydraulic motor 3 is arranged in the cavity of the first upper connecting base 1 and the formation of the second upper connecting base 2, the present embodiment also comprises the first coupling bar 6 and the second coupling bar 7, the free end of the first coupling bar 6 is provided with the first through hole, the free end of the second coupling bar 7 is provided with the second through hole, first through hole is identical with the diameter of the second through hole, and the inwall of the first through hole and the second through hole is provided with helicitic texture.The rotating shaft part of hydraulic motor 3 is connected with decelerator 4, and decelerator 4 gears meshing has leading screw connecting rod 5, first through hole and the second through hole coaxial sleeve to be connected on leading screw connecting rod 5, and is engaged with leading screw connecting rod 5 by built-in screw thread.The bottom of upper connecting base is provided with lower connecting base, comprises by rivet interlacement between the first lower connecting base 8 and the second lower connecting base 9, two Connection Block, and be distributed in the corner place of Connection Block.The other end and first gripper 10 of the first coupling bar 6 are hinged, and the other end and second gripper 11 of the second coupling bar 7 are hinged, two groups of rivet spaces that the first coupling bar 6 is formed through the first lower connecting base 8 and the second lower connecting base 9.
When hydraulic motor 3 works, leading screw connecting rod 5 changes axial rotating speed the motion of telescopic direction into, the first coupling bar 6 that band is automatically connected on leading screw connecting rod 5 and the second coupling bar 7 move back and forth, simultaneously, first coupling bar 6 drives the first hinged gripper 10 to move, second coupling bar 7 drives the second hinged gripper 11 to move, thus realizes opening and closing of the first gripper 10 and the second gripper 11.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection scope of the present invention.
