[0026] The utility model provides a technical solution:

[0027] See also Figures 1 to 4 A simple maintenance blocking structure installed on an upper beam comprises a car body 10, an upper beam 8 is arranged above the car body 10, and guide rails 9 are arranged on the left and right sides of the car body 10, a fixing plate 6 is installed on one side of the guide rail 9, a body base 1 is arranged on the top side of the car body 10, and a USK safety circuit switch 7 adapted to the position of the body base 1 is installed on one side of the upper beam 8;

[0028] A horizontal slide groove 11 is provided on one end surface of the main body base 1, and a vertical slide groove 12 is provided below the horizontal slide groove 11, and the vertical slide groove 12 is connected to the horizontal slide groove 11;

[0029] A latch 3 is installed inside the main body base 1, and a movable handle 4 that passes through a horizontal slide groove 11 is provided on one side of the latch 3. The switch button of the USK safety circuit switch 7 faces the car body 10. Two groups of vertical slide grooves 12 are provided. The movable handle 4 rotates on the main body base 1 through the vertical slide grooves 12, and the movable handle 4 slides on the main body base 1 through the horizontal slide grooves 11. A horizontal groove 61 is opened inside the fixed plate 6, and the latch 3 passes through the inside of the horizontal groove 61.

[0030] By adopting the above technical solution, when the elevator needs to be inspected, the car body 10 is moved to the bottom of the upper beam 8. At this time, the movable handle 4 is rotated, and the movable handle 4 drives the latch 3 to rotate, and the movable handle 4 moves in the vertical slide groove 12, so that the movable handle 4 moves to the horizontal slide groove 11 position. At this time, the movable handle 4 abuts against the USK safety circuit switch 7 to disconnect the safety circuit, and the movable handle 4 can slide in the horizontal slide groove 11, so that the movable handle 4 drives the latch 3 to slide, and the latch 3 is inserted into the horizontal groove 61 of the fixed plate 6 to fix the car body 10. When the movable handle 4 moves on the horizontal slide groove 11, it is blocked by the horizontal slide groove 11 and cannot be rotated downward, and the length of the movable handle 4 is adapted to the moving distance of the latch 3. When sliding the movable handle 4, the movable handle 4 is always abutted against the USK safety circuit switch 7.

[0031] Specifically, Figure 2 As shown, a limit plate 5 is provided on the surface of the latch 3, and a limit spring 51 is provided between the limit plate 5 and the main body base 1, one end of the limit spring 51 is embedded in the main body base 1, and the other end of the limit spring 51 is fixed on the limit plate 5, the axis of the limit spring 51 and the latch 3 coincide with each other, and the limit spring 51 is sleeved on the outside of the latch 3, and a movable through hole 2 penetrating the main body base 1 is provided at the connection between the latch 3 and the main body base 1, and the limit spring 51 is located inside the movable through hole 2.

When the movable handle 4 is located in the vertical slide groove 12, the limit spring 51 is in a stretched state. After the movable handle 4 rotates to enter the horizontal slide groove 11, the limit plate 5 drives the pin 3 to move under the tension of the limit spring 51, so that the pin 3 enters the horizontal groove 61 of the fixed plate 6 and is fixed.

[0033] Working principle: the car body 10 rises to the bottom of the upper beam 8 through the guide rail 9, and the movable handle 4 is rotated, and the movable handle 4 drives the latch 3 to rotate, and the movable handle 4 moves in the vertical slide groove 12, so that the movable handle 4 moves to the horizontal slide groove 11 position. When the movable handle 4 is in the vertical slide groove 12, the limit spring 51 is in a stretched state. After the movable handle 4 rotates to enter the inside of the horizontal slide groove 11, the limit plate 5 drives the latch 3 to move under the tension of the limit spring 51, so that the latch 3 enters the horizontal groove 61 of the fixed plate 6 and is fixed. The movable handle 4 abuts against the USK safety circuit switch 7 to disconnect the safety circuit, and the movable handle 4 can slide in the horizontal slide groove 11, so that the movable handle 4 drives the pin 3 to slide, and the pin 3 is inserted into the horizontal groove 61 of the fixed plate 6 to fix the car body 10. When the movable handle 4 moves on the horizontal slide groove 11, it is blocked by the horizontal slide groove 11 and cannot rotate downward, and the length of the movable handle 4 is adapted to the moving distance of the pin 3.
