DETAILED DESCRIPTION

[0022] The present invention is further described in detail below in conjunction with the embodiments:

[0023] The high-voltage cabinet top maintenance device provided by the utility model can prevent construction workers from falling from the top of the high-voltage cabinet during the process of construction workers repairing the high-voltage cabinet by arranging a lifting guardrail, thereby greatly improving the safety performance; and by arranging an elastic belt to protect the maintenance workers, the number of rotating rods on the lifting guardrail can be reduced, reducing costs, and at the same time, the impact of the rotating rods on the construction workers during the maintenance process can be reduced.

[0024] Specific structure such as Figure 1-Figure 5 As shown, it includes a high-voltage cabinet 1 installed inside a power distribution room 2, and a lifting guardrail 5 that can be raised and lowered for protection and a telescopic ladder 7 that is convenient for going up and down the top of the high-voltage cabinet are arranged above the high-voltage cabinet 1.

[0025] Two mounting blocks 4 are installed on the top of the inner wall of the distribution room 2. Each rotating shaft 51 passes through a mounting block 4 for rotation, and at least one matching bearing is provided on the mounting block 4, which ensures the stability of the lifting guardrail 5 during the lifting process and improves the strength of the lifting guardrail 5.

[0026] The lifting guardrail 5 includes two horizontally arranged rotating shafts 51, one is a driving rotating shaft and the other is a driven rotating shaft. One end of the driving rotating shaft passes through the mounting block 4 and is rotatably mounted on the inner side wall of the power distribution room 2, and the other end is connected to the main shaft of the rotating motor 3 to provide power for the rotation of the driving rotating shaft, and the rotating motor 3 is fixed on the side wall of the power distribution room 2. The middle part of the driven rotating shaft passes through the mounting block 4, and the two ends are rotatably mounted on the inner side wall of the power distribution room 2 respectively.

[0027] A plurality of mounting shafts 54 are evenly spaced between the two rotating shafts 51. Bevel gears 57 are arranged at both ends of the mounting shafts 54. Bevel gears 53 are arranged at corresponding positions on the rotating shafts 51. Bevel gears 53 are meshed with bevel gears 57. The meshed bevel gears 53, 57 and mounting shafts 54 form a transmission component, so that the active rotating shaft drives the driven rotating shaft to rotate.

[0028] Rotating rods 52 perpendicular to the mounting shaft 54 ​​are fixed to both ends of the mounting shaft 54. The rotating rods 52 swing along with the rotation of the mounting shaft. The bottom ends of the rotating rods 52 at each end of the mounting shaft 54 ​​are hinged with guardrail bases 55. When the rotating motor 3 drives the rotating shaft to rotate, the mounting shaft 54 ​​rotates accordingly. At this time, the rotating rods 52 swing accordingly, so that the guardrail base 55 rises and falls accordingly, thereby realizing the lifting and lowering of the lifting guardrail 5.

[0029] A mounting groove 56 is provided on the top of the guardrail base 55 for accommodating the rotating rod 52 when the lifting guardrail 5 is raised.

[0030] Specifically, the distance between the mounting shafts 54 is greater than the length of the rotating rod 52, ensuring that the rotating rod 52 can be completely received in the mounting groove 56. The distance between the two guardrail bases 55 is greater than the width of the high-voltage cabinet 1, ensuring that the user will not be blocked by the lifting guardrail 5 during the process of inspecting the top of the high-voltage cabinet 1.

[0031] A groove is provided on the side of the guardrail base 55 close to the high-voltage cabinet 1, and the groove matches the edge of the top surface of the high-voltage cabinet, so that the guardrail base 55 can be stuck on the edge of the top surface of the high-voltage cabinet 1 when it is lowered. In this way, a gap can be avoided between the edge of the top surface of the high-voltage cabinet 1 and the guardrail base 55, preventing construction workers from accidentally putting their feet into the gap, causing injuries to the construction workers, and improving safety performance.

[0032] The telescopic ladder 7 is installed at one end of the guardrail base 55 away from the high-voltage cabinet 1, which is convenient for users to get on and off the high-voltage cabinet 1. The installation position of the telescopic ladder 7 can ensure that the telescopic ladder 7 will not hit the high-voltage cabinet 1 during the lifting and lowering process of the lifting guardrail 5, thereby avoiding affecting the lifting and lowering of the lifting guardrail 5.

[0033] Specifically, the telescopic ladder 7 includes a telescopic ladder body 72 with a pedal and a telescopic section 73. The telescopic section 73 is arranged inside the telescopic ladder body 72 and can slide up and down to extend and retract the telescopic ladder 7. The telescopic ladder body 72 and the telescopic section 73 are provided with a fixing block 71, and the bottom of the telescopic ladder body 72 and the bottom and top of the telescopic section 73 are provided with through holes into which the fixing block 71 can be inserted, and the fixing block 71 can be used to fix the telescopic ladder 7. The length of the telescopic ladder 7 after extension is greater than the height of the guardrail base 55 from the ground when the guardrail base 55 moves to the lowest position, thereby reducing the force on the lifting guardrail 5 when the user climbs the telescopic ladder 7.

[0034] An elastic band 6 is provided between the top of the guardrail base 55 and the bottom of the mounting block 4. The elastic band 6 can seal the space between the adjacent rotating rods 52 to prevent the protective effect of the lifting guardrail 5 from being affected due to the large distance between the rotating rods 52. The elastic band 6 has a certain elasticity to reduce the impact of the elastic band 6 on the user.

[0035] The working principle of the utility model is as follows: the rotating motor 3 is started, the rotating shaft 51 starts to rotate, the mounting shaft 54 ​​starts to rotate under the cooperation of the bevel gear 1 53 and the bevel gear 2 57, the guardrail base 55 descends, and the rotating motor 3 is stopped when the guardrail base 55 descends to the limit, and the guardrail base 55 is pushed so that the edge of the top surface of the high-voltage cabinet is stuck in the groove of the guardrail base 55. The fixing block 71 is pulled out, and the telescopic section 73 falls. When the telescopic section 73 drops to the lowest point, the fixing block 71 is pushed to fix the telescopic section 73, and the construction personnel climb up to the top surface of the high-voltage cabinet 1 through the telescopic ladder 7 for maintenance.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
