Description

Technical Field

[0001] This utility model belongs to the field of climbing machine technology, specifically a power transmission line tower climbing robot. Background Technology

[0002] Transmission line tower climbing robots are robots capable of climbing and inspecting transmission line towers. Employing a modular design, these robots can automatically climb and overcome obstacles on the main structure of the tower, making them suitable for various complex environments. However, current transmission line tower climbing robots are prone to accidental falls and damage when climbing on uneven poles because the fixing mechanism cannot fully fit the pole's surface. Therefore, a new type of transmission line tower climbing robot is needed that can easily climb poles with irregular surfaces. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a power transmission line tower climbing robot, which solves the problem that when the power transmission line tower climbing robot is climbing on uneven poles, the fixing mechanism cannot fully fit the surface of the pole, which makes the power transmission line tower climbing robot prone to accidental fall during use, and thus damage the power transmission line tower climbing robot.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a power transmission line tower climbing robot, comprising an upper support plate, a motor fixedly connected to the inner wall of the upper support plate, a threaded rod installed on one side of the motor, one end of the threaded rod being connected to the upper support plate via a bearing, the threaded rod having threads in opposite directions, two threaded plates threadedly engaged on the threaded rod, a first slider fixedly connected to one side of the threaded plates, a first sliding groove provided on one side of the upper support plate, the inner wall of the first sliding groove being slidably engaged with the outer side of the first slider, a shell fixedly connected to one side of the first slider, a second slider slidably engaged with the inner wall of the shell, a second sliding groove provided on the second slider, a first column slidably engaged with the inner wall of the second sliding groove, the first column being fixedly connected to the shell, fixing blocks provided on both sides of the second slider, the fixing blocks being through-engaged with the inner wall of the shell, a third sliding groove provided on the fixing blocks, a second column slidably engaged with the inner wall of the third sliding groove, the second column being fixedly connected to the shell.

[0005] As a further embodiment of this utility model: a cylinder is fixedly connected to the bottom side of the upper support plate, a piston rod is installed on the bottom side of the cylinder, and a lower support plate is fixedly connected to the bottom end of the piston rod.

[0006] As a further embodiment of this utility model: two connecting plates are fixedly connected to one side of the lower support plate, an electric push rod is installed on one side of the connecting plate, and a fixing plate is fixedly connected to one end of the electric push rod.

[0007] As a further embodiment of this utility model: two telescopic rods are installed on one side of the fixing plate, and one end of the telescopic rod is fixedly connected to the connecting plate.

[0008] As a further embodiment of this utility model: two first U-shaped frames are fixedly connected to one side of the upper support plate. A first rotating arm is hinged to the first U-shaped frame by a pin. A second rotating arm is hinged to the bottom end of the first rotating arm by a pin. A second U-shaped frame is hinged to the bottom end of the second rotating arm by a pin. The second U-shaped frame is fixedly connected to the lower support plate.

[0009] As a further embodiment of this utility model: an anti-slip sleeve is fitted onto one side of the fixing block, and the anti-slip sleeve has anti-slip texture.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This power transmission line tower climbing robot, by setting up a motor, threaded rod, threaded plate, first slider, first slide groove, outer shell, second slider, and fixing block, allows the robot to be fixed on irregularly shaped power transmission line towers. When the robot is fixed on the tower, the operator starts the motor, which drives the threaded rod to rotate. Because the threaded rod has threads in opposite directions, the threaded rod pushes two threaded plates to move towards each other. The threaded plates drive the first slider to slide in the first slide groove. The first slider drives the outer shell and fixing block to move. After the fixing block contacts the tower, it retracts into the outer shell and pushes the second slider to move until the fixing block is completely in contact with the surface of the tower. This facilitates fixing on towers with irregular surfaces and prevents the robot from slipping off the tower during operation because the fixing mechanism cannot fully fit the tower due to the irregular surface. This improves the versatility and stability of the robot during fixing.

[0012] 2. This transmission line tower climbing robot, by setting up an upper support plate, a first U-shaped frame, a first rotating arm, and a second rotating arm, allows the upper support plate to move the first U-shaped frame upwards during the robot's ascent. The first U-shaped frame then moves the first rotating arm upwards, and the first rotating arm rotates the second rotating arm. This facilitates the movement of the upper support plate and limits its movement, preventing the upper support plate from detaching during the robot's ascent and causing it to fall off the tower, thus improving the overall stability of the robot.

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: a transmission line tower climbing robot, including an upper support plate 1, a cylinder 15 fixedly connected to the bottom side of the upper support plate 1, a piston push rod 16 installed on the bottom side of the cylinder 15, and a lower support plate 17 fixedly connected to the bottom end of the piston push rod 16. Because of the piston push rod 16, when the robot climbs, the operator starts the cylinder 15, the cylinder 15 causes the piston push rod 16 to extend, and pushes the cylinder 15 and the upper support plate 1 to move upward, which facilitates the rapid and automatic lifting of the height of the upper support plate 1, saves manpower and material resources, and improves the working efficiency of the robot.

[0019] Two connecting plates 18 are fixedly connected to one side of the lower support plate 17. An electric push rod 19 is installed on one side of the connecting plate 18. A fixing plate 20 is fixedly connected to one end of the electric push rod 19. Because of the fixing plate 20, when fixing the lower support plate 17, the operator activates the electric push rod 19 on the connecting plate 18. The electric push rod 19 extends and pushes the fixing plate 20 towards the road pole until the fixing plate 20 is completely in contact with the road pole. This prevents the lower support plate 17 from sliding during the robot's climbing process, which would cause the robot to fail to climb. This improves the stability when the first support plate is fixed. A motor 2 is fixedly connected to the inner wall of the upper support plate 1. A threaded rod 3 is installed on one side of the motor 2. The end is connected to the upper support plate 1 via a bearing. The threaded rod 3 has threads in opposite directions. Two threaded plates 4 are threaded onto the threaded rod 3. A first slider 5 is fixedly connected to one side of the threaded plate 4. A first sliding groove 6 is opened on one side of the upper support plate 1. Two telescopic rods 7 are installed on one side of the fixed plate 20. One end of the telescopic rod 7 is fixedly connected to the connecting plate 18. Because of the telescopic rod 7, when the fixed plate 20 moves, the telescopic rod 7 extends or shortens along with the fixed plate 20. While limiting the fixed plate 20, it ensures the normal movement of the fixed plate 20 and prevents the fixed plate 20 from shifting during movement, which would cause the lower support plate 17 to become unstable. This improves the stability of the fixed plate 20 during movement.

[0020] Two first U-shaped frames 21 are fixedly connected to one side of the upper support plate 1. A first rotating arm 22 is hinged to the first U-shaped frame 21 by a pin. A second rotating arm 23 is hinged to the bottom end of the first rotating arm 22 by a pin. A second U-shaped frame 24 is hinged to the bottom end of the second rotating arm 23 by a pin. The second U-shaped frame 24 is fixedly connected to the lower support plate 17. The inner wall of the first sliding groove 6 is slidably engaged with the outer side of the first slider 5. A housing 8 is fixedly connected to one side of the first slider 5. A second slider 9 is slidably engaged with the inner wall of the housing 8. A second sliding groove 10 is provided on the second slider 9. A first column 11 is slidably engaged with the inner wall of the second sliding groove 10. The second slider 9 is fixedly connected to the outer shell 8. Fixing blocks 12 are provided on both sides of the second slider 9. The fixing blocks 12 are inserted and snapped into the inner wall of the outer shell 8. A third sliding groove 13 is provided on the fixing block 12. A second column 14 is slidably snapped into the inner wall of the third sliding groove 13. The second column 14 is fixedly connected to the outer shell 8. An anti-slip sleeve 25 is fitted on one side of the fixing block 12. The anti-slip sleeve 25 is provided with anti-slip texture. Because of the anti-slip sleeve 25, the fixing block 12 is prevented from directly contacting the road pole, which increases the friction between the fixing block 12 and the road pole and prevents the robot from slipping due to the surface of the fixing block 12 being too smooth, thus improving the stability of the robot.

[0021] The working principle of this utility model is as follows: When the robot climbs, the operator activates the electric push rod 19 on the connecting plate 18. The electric push rod 19 extends and pushes the fixed plate 20 towards the road pole until the fixed plate 20 is completely in contact with the road pole. Because the connecting plate 18 is fixedly connected to the lower support plate 17, the lower support plate 17 is fixed. The operator then activates the cylinder 15, which causes the piston push rod 16 to extend and pushes the cylinder 15 and the upper support plate 1 upward. After the upper support plate 1 moves to the appropriate position, the operator activates the motor 2. The motor 2 drives the threaded rod 3 to rotate. The threaded rod 3 has threads in opposite directions. The threaded rod 3 pushes two threaded plates 4 to move towards each other. The threaded plates 4 drive the first slider 5 to slide in the first groove 6. The first slider 5 drives the outer shell 8 and the fixed block 12 to move. After the fixed block 12 contacts the road pole, it retracts into the outer shell 8 and pushes the second slider 9 to move until the fixed block 12 is completely in contact with the surface of the road pole. Then the electric push rod 19 is activated to retract, thereby separating the fixed plate 20 from the road pole. Finally, the cylinder 15 is activated to retract the piston push rod 16 and pull the lower support plate 17 upward to complete one climbing cycle.
