Abstract

The utility model relates to a lumbering tethering tool, which comprises a telescopic operation rod (1), a rope (6) which can be connected to the top end of the telescopic operation rod and a hook (3) which is fastened on the rope; a magnet ring (7) is fixed on the position which is 20 to 30 mm away from the head of the telescopic operation rod; an iron ring (4) which can lead into the telescopic operation rod is fixed at the back of the hook (3); and a circular ring (5) for fastening the rope is arranged on the tail part of the hook. The lumbering tethering tool has the advantages that the climbing is not required, the tool is convenient to operate, the operation is safe, and the lumbering efficiency is high.

Description

Lumbering tether instrument

Technical field

The utility model is applicable to falls trees and controls the trees toppling direction, need fasten the lumbering operation device of control rope, is particularly suited near the trees felling application apparatus technical field of structures high voltage transmission line paths.

Background technology

The parameatal trees of cleaning high-tension line are the work that the power worker often carries out.Along with power network development is more and more faster, the amount of falling trees is increasing.And general two the bigger risks that exist of falling trees around the power circuit: the one, trees may be poured onto on the charged high-tension line, causing discharge to jeopardize the ground personal security that chops at a tree; The 2nd, for preventing trees guidance tape electric line, the staff must climbing go up the trees tether usually, in case accidentally drop then very likely cause operating personnel's injures and deaths of falling, a lot of getting an electric shock and dying and the high-altitude death by accident of falling of causing because of falling trees has been taken place in the power system.

Summary of the invention

The purpose of this utility model provides a kind of in order to overcome the weak point that the above-mentioned existing draw-gear of falling trees exists just and need not climb, easy to operate, job safety, lumbering tether instrument that lumbering efficient is high.

The purpose of this utility model is achieved by the following technical solution.

Lumbering tether instrument comprises a flexible action bars, is connected the rope and the hook of fastening on rope on flexible action bars top; At the fixedly connected magnet ring in 20～30mm place apart from flexible operation club head; Be fixed with an iron ring that can penetrate flexible action bars at the back place of hook; Be provided with an annulus of fastening rope at the hook afterbody.

Adopt the utility model, when lumbering, the operator need not climb on the tree can be suspended to hook upward desired height of tree like a cork, when lumbering, personnel strain rope towards assigned direction by terrestrial operation, the trees that traction is cuted down fall towards assigned direction, prevent that trees are pressed onto transmission line of electricity and operating personnel.The utility model is easy to operate, job safety, lumbering efficient height.

Further set forth the utility model content below in conjunction with accompanying drawing.

Fig. 2 uses schematic diagram for the utility model.

Embodiment

See Fig. 1, lumbering tether instrument comprises a flexible action bars 1, can be connected the rope 6 and the hook 3 of fastening on rope on flexible action bars top; At the fixedly connected magnet ring 7 in 20～30mm place apart from flexible operation club head 2; Be fixed with an iron ring 4 that can penetrate flexible action bars in hook 3 hook back of a bow centre, magnet ring and iron ring are by the sticking mutually suction of magnetic force.Be provided with an annulus 5 that is used to fasten the rope that draws trees at the hook afterbody.Flexible action bars elongation back length shortens back length and is no more than 2000mm about 10000mm, and material is light firm aluminium or carbon fiber pipe, and is during use, extending to Len req; The time spent is collapsible not shorter, easy to carry and store.The hook 3 of tether adopts aluminum alloy materials certain toughness and lighter weight to make, and the diameter that the opening diameter of hook is fallen trees according to need can adopt 150mm, 250mm, 350mm not to wait.Iron ring 4 highly is 10-20mm, and the circle wall thickness is about 5mm.The drag rope length that the control trees are swung to is more than 1.2 times of height of falling trees, and generally uses length to be 20000mm or 30000mm, and material is the silk insulation ropes.Rope can be fixedly connected on flexible action bars top, also can not connect, and does not all influence use.

During use, the staff is the drag rope 6 of falling trees in hook afterbody annulus 5, and flexible operation club head 2 is inserted in the iron ring 4 of hook, magnet ring 7 is inhaled, to keep the stability of hook by magnetic force is sticking mutually with iron ring 4.The staff is by the flexible action bars 1 that raises, as shown in Figure 2, tether hook 3 is hung on 8 the proper height (being generally 1/2nd places of trees overall height) of need falling trees, the personnel that treat drag rope are after tight rope rope 6 is dragged on ground, the staff gets and takes off flexible action bars, can cut down trees.Trees are in the process of falling, and drag rope is controlled it and fallen to the opposite direction in high-voltage line road, guarantee transmission line of electricity and lumbering personnel's safety.

Claims

1. lumbering tether instrument is characterized in that, comprises a flexible action bars (1), can be connected the rope (6) on flexible action bars top and fasten hook (3) on rope; At the fixedly connected magnet ring in 20～30mm place (7) apart from flexible operation club head (2); Be fixed with an iron ring (4) that can penetrate flexible action bars at the back place of hook (3); Be provided with an annulus (5) of fastening rope at the hook afterbody.
