Description
Technical Field
The utility model relates to a transmission line overhauls the field, particularly, relates to a felling is to controlling means.
Background
The channel trees not only harm the safe operation of the line and cause the trip of the line, thereby causing the power failure of the line, even causing the total station voltage loss of the transformer substation, but also possibly causing casualties of people and animals, the trees are not well controlled to fall in the cleaning process of the channel trees, and the operating personnel can be caused to be injured by electric shock, and in order to ensure the normal operation of the transmission line, the trees in the channel of the transmission line must be cleaned regularly. In the maintenance operation of the power transmission line, the proportion of the tree cleaning work of the channel is large.
When the passageway obstacles are felled and cleaned, because field personnel misjudge trees can not fall to the guide line side, so the safety measure for controlling the trees to fall is not taken, the trees fell to the line side, the safety distance of the guide line to the trees is not enough, and meanwhile, the guide line discharges to the trees, so that operating personnel are burnt by electric arc, even die, and similar accidents happen.
In the actual channel tree cutting and shearing process, the cutting and shearing trees are pulled to the direction opposite to the direction of the conducting wire by adopting a control method of a rope, and an operator must climb onto the trees to tie the rope at a proper position of the cutting and shearing trees. The trees cut by cutting are mainly eucalyptus and the like, the trunk is thin, but the trees are high, few and fragile in branches and difficult to climb. The trees are cut a lot of at every operation, and personnel climb trees repeatedly, and intensity of labour is big, increases personnel's risk of falling simultaneously. The requirement of climbing trees on the physical condition of operators is high, and the time for climbing trees is long, so that the working efficiency is low.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a felling is to controlling means, its process of saving the staff and climbing the tree treats that the trees play the effect of felling and falling to control, and is applicable to the trees of waiting to fell of different diameters, easy operation, labour saving and time saving, and the security is high.
The embodiment of the utility model discloses a realize through following technical scheme:

The rope fixing portion 600 is disposed at an end of the first connecting rod 300 close to the third point 510, and the pulling rope 700 is detachably connected to the rope fixing portion 600.
The inventor finds that the specific gravity of the channel tree cleaning work is large in the overhauling operation of the power transmission line. Because field personnel misjudge trees can not fall to the wire side, or field personnel omit the operation of climbing trees and tying up the rope, can cause the potential safety hazard.
The inventor invents a felling direction-reversing control device 10 which comprises a first tree clamping hook 100, a second tree clamping hook 200, a first connecting rod 300, a second connecting rod 400, a supporting rod 500, a rope fixing part 600 and a traction rope 700.
The first tree hook 100 is hinged to the second tree hook 200, the first tree hook 100 is hinged to the first connecting rod 300, the second tree hook 200 is hinged to the second connecting rod 400, and the first connecting rod 300 is hinged to the second connecting rod 400, so that the first tree hook 100 and the second tree hook 200 can be opened at a large enough angle to meet the requirement of controlling the direction of felling of trees with different diameters.
The first tree-clamping hook 100 and the second tree-clamping hook 200 are conveyed to the designated positions of the trees to be felled through the supporting rod 500, the pulling rope 700 is detachably connected with the rope fixing portion 600, and the rope fixing portion 600 is arranged at one end of the first connecting rod 300 close to the third point 510. An operator pulls the pulling rope 700, so that the pulling rope 700 forms a certain included angle with the supporting rod 500, and the first connecting rod 300 and the first tree hook 100 can rotate relatively through the pulling rope 700. Thereby driving the first tree hook 100 and the second tree hook 200 to rotate with each other, and thus causing the second tree hook 200 and the second link lever 400 to rotate with each other. The second connecting rod 400 and the first connecting rod 300 also rotate around the third point 510.
Rotation through first card tree hook 100 and second card tree hook 200 for contained angle between first card tree hook 100 and the second card tree hook 200 reduces, thereby can make sawtooth portion 120 of first card tree hook 100 and the sawtooth portion 120 card of second card tree hook 200 advance the assigned position of waiting to fell the trees, form the felling and fall to controlling means 10 and wait to be connected between the trees, provide the effect of control falling to the felling process, save the process that the staff climbed the tree, time saving and labor saving, and the security is high.
The support rod 500 comprises a long rod and a connector which are detachably connected, and one end of the first connecting rod 300 away from the first point 110, one end of the second connecting rod 400 away from the second point 210, and the connector are both hinged to the third point 510. The worker sends the first tree hook 100 and the second tree hook 200 to the set position of the tree to be felled by holding the long rod. After the saw tooth portion 120 of the first tree hook 100 and the saw tooth portion 120 of the second tree hook 200 are clamped into the designated positions of the trees to be felled, the worker can tear the long rod, so that the long rod is separated from the connector.

To sum up, such felling is fallen to controlling means 10 and is saved the process that the staff climbed the tree, treats that the felling trees play the effect of felling and falling to control, and is applicable to the trees of waiting to fell of different diameters, easy operation, labour saving and time saving, and the security is high.
Further, referring to fig. 1 and 2, the first point 110 and the second point 210 are symmetrically disposed with respect to the axial direction of the support rod 500.
The axial direction of the supporting rod 500 is used as a reference, the first point 110 and the second point 210 are symmetrically arranged, so that the rotating angles of the first tree clamping hook 100 and the first connecting rod 300 around the first point 110 and the rotating angles of the second tree clamping hook 200 and the second connecting rod 400 around the second point 210 can be kept consistent, and the sawtooth part 120 of the felling and inverting control device 10 can be conveniently clamped with a tree to be felled.
Further, referring to fig. 1 and 2, the first point 110, the second point 210, the third point 510, and the fourth point 130 sequentially form a parallelogram.
When the first tree hook 100 and the second tree hook 200 rotate around the fourth point 130, the angle of rotation of the first tree hook 100 relative to the first tree hook is the same as the angle of rotation of the second tree hook relative to the first tree hook, and on the premise that symmetry is met, time and labor are saved.
Further, referring to fig. 2 and 3, a first hollow cavity 140 is disposed at an end of the first tree clasp 100 close to the first point 110, and the second tree clasp 200 is disposed through the first hollow cavity 140 and hinged to the fourth point 130 together with the first tree clasp 100.
The second hook 200 and the first hook 100 are rotated relative to each other about the fourth point 130, as far as possible with little wear on each other. The second tree hook 200 and the first tree hook 100 are subjected to a surface polishing process. The second tree hook 200 penetrates through the first hollow cavity 140, and the first hollow cavity 140 limits the movement of the second tree hook 200 in the direction relative to the first tree hook 100, thereby facilitating the overall stability of the felling and inverting control device 10.
