Description

Technical Field

[0001] The utility model relates to the field of operating vehicles, in particular to an operating vehicle for inspecting and maintaining a transformer substation. Background Art

[0002] With the continuous development of my country's economy, people have more stringent requirements for the stability of the power grid. In order to ensure the stability of the power grid, the substation should ensure that the equipment can perform its own performance during operation. Then the equipment needs to be regularly and comprehensively inspected.

[0003] During the inspection and maintenance process, the existing substation inspection and maintenance work vehicles are generally lifted by cylinders. If the cylinder fails during operation, the lifting platform will drop suddenly, and the workers above the lifting platform will be threatened. The existing substation inspection and maintenance work vehicles lack emergency safety protection equipment, which leads to safety hazards during the use of the work vehicle, and the life safety of the workers cannot be effectively guaranteed. In addition, dust is easily introduced between the base and the insulating platform of the existing work vehicle lifting device, affecting the normal lifting operation of the scissors fork parts inside. Therefore, improvement is needed. Utility Model Content

The end of the second sliding block 8 is located inside the second slide groove 7, and the second sliding block 8 can slide along the length direction of the second slide groove 7. One end of the second sliding block 8 is fixedly connected to the scissors fork member 1, one side of the second sliding block 8 is fixedly connected to the second hydraulic rod 9, one end of the second hydraulic rod 9 is fixedly connected to the top of the second slide groove 7, the upper surface of the base 2 is fixedly connected to the vertical axis 10, and the vertical axis 10 is sleeved with a buffer spring 11. The upper surface of the anti-fall plate 3 is provided with a through hole, and the vertical axis 10 is inserted in the through hole. The upper surface of the anti-fall plate 3 is fixedly connected to a dust cover 12, and one end of the dust cover 12 is fixedly connected to the second anti-fall plate 19. There are two groups of scissor parts 1, and the two groups of scissor parts 1 are arranged in parallel transversely. The scissor parts 1 include fork rods 101 and support rods 102. The scissor parts 1 are composed of fork rods 101 that are cross-hinged with each other. The ends of the fork rods 101 are hinged with the ends of the adjacent fork rods 101, and the middle of the fork rods 101 is hinged with the middle of the adjacent fork rods 101. The two ends of the support rods 102 are respectively fixedly connected to the two groups of scissor parts 1. The lower surface of the base 2 is fixedly connected with a support plate 13, and the lower surface of the support plate 13 is fixedly connected with a hydraulic lifting rod 14. The bottom end of the hydraulic lifting rod 14 is fixedly connected with a support foot 15.

The dust cover 12 is stretched when the insulating platform 17 rises, and is compressed when the insulating platform 17 falls.

[0024] When in use, the staff moves the substation maintenance work vehicle to the maintenance position through the universal wheel 16. During the movement, the hydraulic lifting rod 14 is controlled to rise by the controller, so that the height of the hydraulic lifting rod 14 is lower than the height of the universal wheel 16. After moving to the location, the hydraulic lifting rod 14 is controlled to descend by the controller, so that the height of the hydraulic lifting rod 14 is higher than the height of the universal wheel 16, so that the support leg 15 stably props up the work vehicle, and the staff carries the maintenance tools and stands on the insulating platform 17.

At the same time, the dust cover 12 is stretched with the rise of the second anti-fall plate 19 to prevent dust from entering the scissors fork member and affecting the rise of the scissors fork member. The first hydraulic rod 6 and the second hydraulic rod 9 stop extending, which limit the scissors fork member 1, so that the staff can work smoothly at a high place. After the operation is completed, the controller retracts the first hydraulic rod 6 and the second hydraulic rod 9, respectively driving the first slider 5 and the second slider 8 to slide in the first slide 4 and the second slide 7 in opposite directions, so that the scissor-type member 1 drives the anti-fall plate 3 and the insulating platform 17 to descend to the lowest position, completing the operation. When the lifting mechanism formed by the scissor-type member 1 suddenly fails during the operation of the staff, the guardrail 18 prevents the staff from falling directly, and the potential energy of the insulating platform 17 is first reduced by the first hydraulic rod 6 and the second hydraulic rod 9 arranged horizontally. The downward movement of the anti-fall plate 3 will squeeze the buffer spring 11 on the vertical shaft 10, so that most of the downward potential energy is offset by the elastic potential energy, ensuring the life safety of the staff.
