Description

Technical Field

[0001] The invention relates to the technical field of high-voltage line deicing, and in particular to a high-voltage line segmented obstacle-crossing deicing machine. Background Art

[0002] At present, my country has room for improvement in deicing and snow removal of high-voltage lines. High-voltage wires may fail in winter due to accumulation of snow or frost, especially in cold weather, when water vapor or snow condenses on power lines to form a thick layer of ice. The use of lead screws to control the moving wheels to overcome obstacles and squeeze the high-voltage wires for deicing cannot guarantee the speed and completeness of deicing. In order to ensure the stable operation of the power system and prevent potential risks and damage caused by snow and frost, it is necessary to improve the existing deicing technology.

[0003] For example, the patent disclosed by application number CN201921814422.7 includes an obstacle crossing actuator, a motion actuator, and an ice-breaking actuator. The motion actuator is located on one side of the obstacle crossing actuator, and the motion actuator is located on the top of the obstacle crossing actuator. The position of the moving wheel is controlled by the lead screw to achieve the effect of crossing obstacles such as insulators. Although the effect of obstacle crossing and de-icing on the high-voltage line can be achieved, the lead screw needs to be alternately controlled to move when crossing the obstacle, which is less efficient. It breaks the ice by squeezing the high-voltage line, and the effect is not ideal when facing a thicker ice layer. Summary of the invention

[0004] Therefore, the present invention solves the technical problems in the prior art that the high-voltage line de-icing device alternately controls the movement of the lead screw to achieve obstacle crossing, which has low efficiency, and breaks ice by squeezing the high-voltage line, which has unsatisfactory effect when facing a thicker ice layer; the present invention provides a high-voltage line segmented obstacle-crossing and de-icing machine, which overcomes obstacles by rotating the machine in segments, and in terms of de-icing, the ice layer is impacted by a crank rocker mechanism to complete the de-icing work, thereby improving the obstacle crossing and de-icing efficiency.

[0005] The high-voltage line segmented obstacle-crossing and deicing machine provided by the present invention specifically includes a deicing mechanism, an obstacle-crossing mechanism, and a moving mechanism; the entire device is bilaterally symmetrical in space, and the deicing mechanism is installed in front of the front moving platform, and its direction is consistent with the moving direction of the entire device, and the front-back direction is based on the moving direction of the device; it specifically includes a front mounting plate, a first driving motor, a crank rocker mechanism, a deicing brush bracket, and a deicing brush. When the first driving motor starts to work, it drives the crank to rotate, thereby driving the impact hammer to repeatedly impact the ice layer up and down. When the machine moves forward, the high-voltage line after the impact is acted on by the deicing brush, and the ice on the high-voltage line is further removed;

[0006] Furthermore, the obstacle-crossing mechanism is installed inside the middle moving platform and is connected to the front moving platform and the rear moving platform through a rotating joint. When an insulator is encountered during movement, the electric cylinder starts to work, pushing out the first telescopic joint and the second telescopic joint to increase the length of the machine. Subsequently, the steering gears on the first rotating joint and the second rotating joint start to work, respectively driving the front moving platform, the middle moving platform and the rear moving platform to rotate, and after completing a series of actions, the obstacle is crossed.

[0007] Furthermore, the moving mechanism is divided into an active part and a passive part. A driving motor, an active gear, a passive gear and a moving wheel are respectively installed on the front moving platform and the rear moving platform. During normal deicing, only the third driving motor installed on the rear moving platform needs to work, which drives the rear active gear to work, thereby driving the rear passive gear to work, the rear moving wheel starts to rotate, and the entire device starts to move forward. The rear mounting plate is installed at the rear of the rear moving platform.

[0008] Furthermore, the auxiliary wheel is connected to the rear mounting plate through screws and nuts, and the auxiliary device moves. During the obstacle crossing process, when the rear moving platform rotates, the third drive motor thereon stops working, and the second drive motor on the front moving platform starts working, driving the rear moving platform to cross the insulator. After that, the machine is still driven forward by the third drive motor on the rear moving platform.

[0009] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0010] 1. The present invention provides a high-voltage line segmented obstacle-crossing and de-icing machine, which drives a crank to rotate through a first driving motor, and the crank drives a rocker to rotate, thereby driving an impact hammer to reciprocate up and down to impact the ice layer and complete the de-icing work. While the machine moves forward, the impacted ice layer is brushed by a de-icing brush to further remove ice debris; the double de-icing measures improve the de-icing effect, the ice-breaking force is large, and it is suitable for working conditions when the ice layer is thick.

[0011] 2. The present invention provides a high-voltage line segmented obstacle-crossing and de-icing machine. When encountering an insulator during movement, the electric cylinder starts working to increase the length of the machine. Subsequently, the servo on the rotating section starts working to drive the front moving platform, the middle moving platform and the rear moving platform to rotate respectively, and the obstacle is crossed after a series of actions are completed. The segmented obstacle-crossing mechanism is flexible and fast, thereby improving work efficiency and accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
