All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
Referring to fig. 1 to 5, the present embodiment provides an elevated pole saw with a movable gripper, which includes an extension rod 1, a chain saw body 2 and a movable gripper assembly 4. The chain saw body 2 is fixed on the upper part of the extension rod 1 and is used for sawing the sawn object 3. The movable gripper assembly 4 is mounted on the upper part of the extension rod 1 and used for clamping the sawn objects 3, and comprises a first clamping plate 401 which is arranged opposite to the chain saw body 2 and hinged to the top of the extension rod 1, a second clamping plate 402 of which the upper end is hinged to the upper end of the first clamping plate 401, and a hydraulic mechanism for connecting the first clamping plate 401 and the second clamping plate 402; the hydraulic mechanism is used for driving the second clamping plate 402 to cooperate with the first clamping plate 401 to clamp the sawn object 3 so as to enable the sawn object 3 to approach or depart from the chain saw body 2.
It should be noted that when needing to clean the sawn objects 3 such as branches on an overhead line, the operation and maintenance personnel stand on the ground, lift the chain saw main body 2 and the movable gripper assembly 4 to the air through the extension rod 1, enable the first clamping plate 401 and the second clamping plate 402 of the movable gripper assembly 4 to clamp the sawn objects 3 tightly, start the chain saw, and then enable the sawn objects 3 to be close to the chain saw main body 2 through the movable gripper assembly 4 to perform sawing operation on the sawn objects 3, the whole process does not need to ascend, and the operation and maintenance personnel do not need to hold the sawn objects 3 with one hand, which is simple, convenient, safe and reliable; after the sawed object 3 is sawn, the first clamping plate 401 and the second clamping plate 402 clamp the sawn object 3, so that the sawn object 3 can be slowly lowered to the ground through the extension rod 1 and then the first clamping plate 401 and the second clamping plate 402 are loosened, the situation that the sawn object 3 is thrown from high altitude can be avoided, and the personal safety of maintenance personnel and pedestrians on the ground is guaranteed. Therefore, the lopper saw with the movable gripper can solve the problems that the traditional chain saw needs to fix the sawn object 3 with one hand and the sawn object 3 cannot be placed on the ground.
Preferably, the first clamp 401, the second clamp 402 and the extension rod 1 are rotatably coupled about the same rotation shaft 5.
In this embodiment, the movable gripper assembly 4 includes a first hydraulic cylinder 403 and a second hydraulic cylinder 404. The first hydraulic cylinder 403 is connected with the first clamping plate 401 and the second clamping plate 402, and is used for adjusting the included angle between the first clamping plate 401 and the second clamping plate 402. The second hydraulic cylinder 404 is connected to the second clamp plate 402 and the extension rod 1, and is used for adjusting an included angle between the second clamp plate 402 and the extension rod 1.
It should be noted that when the driving end of the first hydraulic cylinder 403 extends out, the included angle between the first clamping plate 401 and the second clamping plate 402 increases, and the object to be sawn 3 can be loosened; when the driving end of the first hydraulic cylinder 403 is retracted, the included angle between the first clamping plate 401 and the second clamping plate 402 is reduced, and the sawn object 3 can be clamped. Specifically, the amount of clamping force between the first clamping plate 401 and the second clamping plate 402 can be adjusted by adjusting the stroke of the driving end of the first hydraulic cylinder 403. When the driving end of the second hydraulic cylinder 404 extends out, the included angle between the second clamping plate 402 and the extension rod 1 is increased, and the sawn object 3 is far away from the chain saw body 2; when the driving end of the second hydraulic cylinder 404 is retracted, the angle between the second clamp plate 402 and the extension rod 1 is reduced, and the sawn object 3 approaches the chain saw body 2. Specifically, the sawing depth of the chain saw body 2 can be adjusted by adjusting the stroke of the driving end of the second hydraulic cylinder 404.
When the chain saw main body 2 performs sawing operation, the sawn objects 3 can generate violent vibration, and the hydraulic cylinder can ensure that enough clamping force is provided between the first clamping plate 401 and the second clamping plate 402 and between the movable gripper assembly 4 and the chain saw main body 2 so as to prevent the sawn objects 3 from loosening.
