specific Embodiment approach 1

[0026] Specific implementation mode one: combine Figure 1 to Figure 2 This embodiment is described. A radial arm saw for cutting branches intruding into power transmission channels in this embodiment includes a car body 1, which also includes a rocker rod 2, a counterweight seat 3, a support frame 5 and a plurality of chainsaws 4, The support frame 5 is installed on the upper end of the car body 1, and the rocker lever 2 is rotated and installed on the support frame 5. The up and down swing angle between the support frame 5 and the rocker lever 2 is regulated by the rocker lever 2 itself, and the A counterweight base 3 is installed at one end, and a plurality of chain saws 4 are installed around the other end of the rocker arm 2 along its length direction.

[0027] In actual use of this embodiment, the rocker lever 2 is an electric rocker arm, and the rocker lever 2 is divided into two parts, one part is used as a lever and shrinks, and the other part is used to hold multiple...

specific Embodiment approach 2

[0029] Specific implementation mode two: combination Figure 1 to Figure 2 This embodiment will be described. The rocker lever 2 of this embodiment is a telescopic rocker lever. Designed in this way, it is convenient to cut down branches according to different heights. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0030] Specific implementation mode three: combination Figure 1 to Figure 2 To describe this embodiment, the connection point between the rocker lever 2 and the support frame 5 in this embodiment can be folded. Such a design makes it easy to install the folded rocker arm on the vehicle, which is convenient for transportation and takes up little space. Other compositions and connections are the same as those in Embodiment 1 or 2.

[0031] The rocker lever 2 used in this embodiment can be folded at the rotation point, which means that it can be folded upwards, which can effectively prevent the rocker lever from being subjected to the gravity of multiple chainsaws and the lateral force in the process of cutting branches. , to prevent the rocker arm from bending and deforming downwards, so as to ensure the service life and safety performance during use.

Abstract

The invention relates to a rocker saw for felling branches intruding into a power transmission channel and a using method of the rocker arm saw, in particular to the rocker arm saw and the using method thereof, and aims to solve the problems of low efficiency, high risk and high resistance existing in manual felling of ultrahigh trees in the prior art. A supporting frame (5) is arranged at the upper end of a vehicle body (1), a rocker arm rod (2) is rotatably arranged on the supporting frame (5), the vertical swing angle between the supporting frame (5) and the rocker arm rod (2) is adjusted through the rocker arm rod (2), a balance weight seat (3) is arranged at one end of the rocker arm rod (2), and a plurality of chain saws (4) are arranged on the periphery of the other end of the rocker arm rod (2). The using method comprises the steps of, 1, determining an advancing route of the rocker arm saw; 2, oiling a chain saw (4); 3, carrying out felling when reaching an area where branches need to be felled; 4, taking back tools; and 5, checking and maintaining the rocker arm saw. The rocker arm saw is used for felling the branches intruding into the power transmission channel.

Description

technical field [0001] The present invention relates to a radial arm saw and its use method, in particular to a radial arm saw for cutting branches intruding into power transmission channels and its use method. Background technique [0002] In daily life, green vegetation has always played a very important role, beautifying the environment, absorbing environmental pollution, providing homes for wild animals and so on. However, the green vegetation around the transmission line has a great potential danger to public safety. Falling trees around transmission lines can hit transmission lines causing power outages and forest fires, trees growing too high under transmission lines, or tree growth near transmission line passages can encroach on transmission passages, posing a serious safety hazard. Therefore, green vegetation management and felling around transmission lines is a very important issue. At present, the pruning of trees around the transmission line and the control of ...
