Description

Technical Field

[0001] The utility model relates to the technical field of insulating saws, in particular to an insulating saw for power engineering maintenance. Background Art

[0002] During the operation and maintenance of current transmission lines, they are easily threatened by branches and bamboos in the channels, especially some fast-growing trees, whose branches overlap with the exposed transmission lines, thus causing unnecessary power outages.

[0003] An existing Chinese patent, publication number CN217903846U, discloses an insulating saw for power maintenance, comprising an insulating operating cylinder, the inner wall of which is slidably connected to an internally threaded insulating cylinder, the top of which is fixedly mounted a mounting cylinder, the inner wall of which is slidably connected to a telescopic cylinder, the top of which is fixedly mounted a mounting plate, and both sides of which are provided with serrated bars; the insulating operating cylinder is internally provided with an adjustment mechanism for driving the movement of the internally threaded insulating cylinder. During actual use, the insulating saw for power maintenance can be activated by a controller based on actual conditions. The rotation of the first motor drives the threaded column, which in turn drives the internally threaded insulating cylinder to rotate. Simultaneously, a limit slider causes the internally threaded insulating cylinder to move upward, thereby automatically adjusting the length of the insulating saw and providing great convenience for the operator.

[0004] However, although the above-mentioned insulated saw can cut high branches, when using the insulated saw to cut high branches, there is a reaction force generated by the branches on the saw. This reaction force may cause certain risks to the operator, including but not limited to the saw bouncing, losing control or the operator losing balance. In order to avoid the above-mentioned risks, the operator needs to use a large force to control the telescopic rod to ensure that the insulated saw on the top of the telescopic rod remains balanced, which increases the labor intensity of the operator. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and to provide an insulating saw for power engineering maintenance. By making the limit block on the first shell or the second shell abut against the tree branch, the reaction force generated by the wire rope when cutting the tree branch is reduced. The operator only needs to push the insulating saw at the end of the telescopic rod toward the tree branch to be cut, avoiding the use of excess force to resist the reaction force generated by cutting the tree branch, thereby reducing the labor intensity of the operator.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] An insulated saw for power engineering maintenance, having a structure as follows Figure 1-Figure 3As shown, it includes a telescopic rod, an insulating saw is provided on the top of the telescopic rod, a power source is installed on the bottom of the telescopic rod, the interior of the telescopic rod is a hollow structure, and a cable connecting the power source and the insulating saw is installed inside the telescopic rod. The insulating saw includes a main shell 7, and a first shell 8 and a second shell 9 are respectively provided on both sides of the top of the main shell 7. The first shell 8 and the second shell 9 form a V-shaped structure at a certain angle. A driving wheel 10 is installed in the main shell 7, and driven wheels 11 are installed in the ends of the first shell 8 and the second shell 9 away from the main shell 7. A steel wire rope 12 is installed on the driving wheel 10 and the two driven wheels 11, and a limit block 13 is installed on the ends of the first shell 8 and the second shell 9 away from the main shell 7.

[0027] When it is necessary to cut a branch at a high place, first stretch out the telescopic rod to ensure that the telescopic rod can extend the insulating saw at its top to a high place, and the power source can be connected to the insulating saw through a cable to drive the insulating saw to work. Since the first shell 8 and the second shell 9 are arranged in a V shape on the top of the main shell 7, and a driving wheel 10 is arranged inside the main shell 7, a driven wheel 11 is arranged in the end of the first shell 8 and the second shell 9 away from the main shell 7, and a wire rope 12 is set on the driving wheel 10 and the two driven wheels 11. When the driving wheel 10 drives the two driven wheels 11 to rotate, it is convenient for the operator to align the wire rope 12 between the two driven wheels 11 with the tree branch, and the wire rope 12 driven by the driving wheel 10 and the two driven wheels 11 can be cut. The steel wire rope 12 between the two driven wheels 11 can cut the tree branch. Since the limit blocks 13 are installed on the top of the first shell 8 and the second shell 9, when the steel wire rope 12 cuts the tree branch, the operator only needs to extend the telescopic rod to the position of the tree branch, so that the limit blocks 13 on the first shell 8 or the second shell 9 abut against the tree branch, thereby reducing the reaction force generated by the steel wire rope 12 when cutting the tree branch. The operator only needs to push the insulated saw at the end of the telescopic rod toward the tree branch to be cut, thereby avoiding using excess force to resist the reaction force caused by cutting the tree branch, thereby reducing the labor intensity of the operator, and also avoiding the insulated saw from bouncing or losing control when cutting the tree branch, thereby affecting the safety of the operator.

[0028] The telescopic rod includes a first sleeve 1 and a second sleeve 2 , wherein the second sleeve 2 is telescopically sleeved inside the first sleeve 1 .

[0029] When it is necessary to cut off a branch at a high place, the second sleeve 2 can be pulled out from the inside of the first sleeve 1, thereby increasing the length of the telescopic rod to facilitate sending the insulated saw at the end of the telescopic rod to a high place to cut off the branch at a high place. When it is necessary to cut off a branch at a relatively low height or to put away the insulated saw, the second sleeve 2 can be retracted into the inside of the first sleeve 1 to facilitate the storage of the insulated saw.

[0030] The power source includes a battery 4 . A mounting base 3 is provided at the bottom of the first sleeve 1 . The battery 4 is detachably mounted on the bottom of the mounting base 3 . A switch is provided at the top of the mounting base 3 .

[0031] The battery 4 is detachably mounted on the bottom of the mounting base 3, which is convenient for quickly replacing the battery 4 when the battery 4 is out of power, and a switch is provided on the top of the mounting base 3, which is convenient for the operator to control the insulated saw on the top of the telescopic rod through the switch.

[0032] The cable is a retractable spiral cable 5 , the top of the spiral cable 5 is connected to the insulating saw, and the bottom of the spiral cable 5 is connected to the power source.

[0033] The battery 4 can transmit electricity to the insulating saw through the spiral cable 5 for the insulating saw to work, and the spiral cable 5 can be stretched when the second sleeve 2 extends from the first sleeve 1, so that when the telescopic rod is stretched to the maximum state, it can still power the insulating saw.

[0034] The driving wheel 10 is provided with a main limiting wheel 14 , and the driven wheel 11 is provided with a slave limiting wheel 15 . Both the main limiting wheel 14 and the slave limiting wheel 15 are provided with limiting grooves 16 , and the steel wire rope 12 is embedded in the limiting grooves 16 .

[0035] The driving wheel 10 can drive the main limiting wheel 14, and the driven wheel 11 can drive the slave limiting wheel 15 to rotate. The main limiting wheel 14 and the slave limiting wheel 15 are both provided with limiting grooves 16 on their circumferential surfaces, and the wire rope 12 is embedded in the limiting grooves 16 on the main limiting wheel 14 and the slave limiting wheel 15 to prevent the wire rope 12 from deviating when cutting the tree branch, thereby limiting the wire rope 12.

[0036] Example 2

[0037] Based on the first embodiment, a motor 6 for driving a driving wheel 10 is provided outside the main housing 7. The driving wheel 10 is detachably mounted on the main housing 7, and the driven wheel 11 is detachably mounted on the second housing 9 and the first housing 8.

[0038] The motor 6 can drive the driving wheel 10 to rotate, and the two driven wheels 11 can be mobilized to rotate through the wire rope 12. When the driving wheel 10 and the driven wheel 11 rotate, the wire rope 12 can rotate to cut the tree branch. The detachable driving wheel 10 and the driven wheel 11 are convenient for removing the wire rope 12 after disassembly, and replacing or maintaining the wire rope 12.

[0039] The first sleeve 1 and the second sleeve 2 are both made of epoxy resin. A threaded groove is provided inside the top end of the first sleeve 1, and a threaded protrusion adapted to the threaded groove is provided outside the bottom end of the second sleeve 2.

[0040] The first sleeve 1 and the second sleeve 2 made of epoxy resin not only have high mechanical strength, but also can play an insulating role, preventing the operator from touching the cables near the tree branch and causing electric shock when cutting the tree branch. Since the threaded grooves and the threaded protrusions can cooperate with each other, after the second sleeve 2 extends out of the first sleeve 1, the threaded grooves and the threaded protrusions cooperate to ensure that the second sleeve 2 will not easily slide back into the first sleeve 1, thereby playing a role of stability.

[0041] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes, additions, subtractions, or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
