The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Referring to fig. 1 and 2, an embodiment of the insulated high branch gripper of the present invention is an insulated high branch gripper, which includes an insulating rod 1, an upper gripping arm 2 and a lower gripping arm 3, wherein the upper gripping arm 2 is located right above the lower gripping arm 3, the upper gripping arm 2 includes a horizontal rod 21 and an arc rod 22, a front end of the horizontal rod 21 is connected to a rear end of the arc rod 22, the arc rod 22 is generally arc-shaped, an inner concave surface of the arc rod faces one side of the lower gripping arm 3, the horizontal rod 21 is in threaded connection with the insulating rod 1, the lower gripping arm 3 is a straight rod, and the lower gripping arm 3 is rotatably connected with the insulating rod 1.
The holding arm 2 can be controlled to move along the vertical direction through the rotation of the insulating rod 1, when a branch needs to be grasped, the holding arm 2 is drawn close to the holding arm 3 downwards, the relative position of the branch can be fixed, the branch can be conveniently sawed by the aid of the hand saw, the problems that trees are shaken due to the fact that the branches are unilateral stressed, the branch is deformed, the distance between the tree lines is changed and the like are effectively solved, supporting force is provided for the hand saw, the trimming efficiency is improved, and the safety factor is increased.
In order to better grasp the branches, a plurality of spike teeth 23 can be arranged on the concave surface of the arc-shaped rod 22, so that when the upper holding arm 2 and the lower holding arm 3 are matched, the spike teeth 23 are clamped into the branches to grasp the branches. In addition, in order to reduce the processing difficulty of the upper holding arm 2, the threaded connection between the insulating rod 1 and the horizontal rod 21 is realized, the upper holding arm 2 can move up and down when the insulating rod 1 rotates, a threaded structure is needed on the horizontal rod 21, but the threaded hole 15 is directly formed in the horizontal rod 21, the number of threads of the threaded hole can be insufficient to support and realize the purpose, therefore, a through hole is formed in the middle of the horizontal rod 21, a nut 24 coaxial with the through hole is fixed on the horizontal rod 21, and the threaded connection between the nut 24 and the insulating rod 1 can be perfectly solved.
When taking place to rotate at last holding arm 2 and insulator spindle 1, though can utilize the branch to block holding arm 2 and make it can not be rotatory along with insulator spindle 1, but cause holding arm 2 and holding arm 3 down to not correspond like this easily, produce the influence to the gripping branch, so even there is the guide bar 4 towards holding arm 3 down at the afterbody of horizon bar 21, and open at the afterbody of holding arm 3 down and have the through-hole, let the lower extreme of guide bar 4 pass the through-hole, when insulator spindle 1 and last holding arm 2 take place relative rotation, it can not rotate along with together to control to hold arm 2, and it can only move along vertical direction to fix holding arm 2, of course, in order to protect holding arm 3 down, reduce and the guide bar 4 between the frictional force, can set up second sleeve 5 in the through-hole.
Similarly, when the insulating rod 1 rotates, the lower holding arm 3 is to be kept stationary relative to the insulating rod 1, a through hole can be formed in the middle of the lower holding arm 3, the first sleeve 6 is arranged, the insulating rod 1 penetrates through the first sleeve 6, the insulating rod 1 is rotatably connected with the first sleeve 6, and the rotatable connection only needs the inner diameter of the first sleeve 6 to be slightly larger than the outer diameter of the insulating rod 1.
As shown in fig. 2 and 3, insulating rod 1 includes insulating grab handle 11 and threaded rod 12, insulating grab handle 11 top can be dismantled with threaded rod 12 and be connected, the top diameter of insulating grab handle 11 is greater than 6 internal diameters of first sleeve, the lower part of threaded rod 12 is rotated and is connected in first sleeve 6, the lower part of threaded rod 12 still is equipped with along the protruding eaves 13 of radial outside extension, protruding eaves 13 is located the top of first sleeve 6, the diameter of protruding eaves 13 is greater than 6 internal diameters of first sleeve, the top surface and the bottom surface of holding arm 3 down are spacing respectively through protruding eaves 13 and insulating grab handle 11 top, thereby it is spacing on the realization is holding arm 3 vertical direction down, prevent holding arm 3 down and appear removing on vertical direction, the removal that just so can be better control holding arm 2 realizes holding arm 2 and holding arm 3's closing up and separation down. Insulating grab handle 11 is connected with dismantling of threaded rod 12, can adopt threaded connection's mode, set up double-screw bolt 14 at the top of insulating grab handle 11, threaded hole 15 is opened in the bottom of threaded rod 12, cooperation through double-screw bolt 14 and threaded hole 15, with insulating grab handle 11 together with the firm connection of threaded rod 12, and convenient to detach in the transportation, can also set up the fixed orifices that passes threaded hole 15 and double-screw bolt 14 on the lateral wall of threaded rod 12 bottom, insert fixed pin 16 in the fixed orifices, when operation insulator spindle 1 rotates like this, ensure that insulating grab handle 11 and threaded rod 12 can not become flexible.
During the equipment, general insulating grab handle 11 can adopt the order gram stick commonly used, will hold down the bottom that arm 3's first sleeve 6 inserted threaded rod 12, is located the below of protruding eaves 13, then screws insulating grab handle 11 and threaded rod 12, makes down arm 3 be located between protruding eaves 13 and the 11 top surfaces of insulating grab handle, then will go up the horizontal pole 21 screw in threaded rod 12 of grab handle, lets guide bar 4 penetrate second sleeve 5 simultaneously, accomplishes the equipment of whole device. During the use, go up holding arm 2 and hold down between the arm 3 with the branch card, then rotatory insulator spindle 1 makes the distance between holding arm 2 and the lower arm 3 reduce, until grasping the branch, then uses the receipt to saw down the branch. And through the rotation control on hold arm 2 and hold arm 3 and draw close down, strengthen the parcel nature of gripper and the operation flexibility to different diameters trees, strengthened the centre gripping effect of gripper, ensure that the branch can not break away from the gripper, easily control trees lodging direction simultaneously, guarantee the safety of personnel and equipment. The insulation rod 1 can also keep enough insulation distance for users, and casualties caused by tree line discharge are avoided.
The above description is only an embodiment of the present invention, but the technical features of the present invention are not limited thereto, and any changes or modifications within the technical field of the present invention by those skilled in the art are covered by the claims of the present invention.
