Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0023] In the description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, the terms "installed", "provided with", "sheathed / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0024] Example 1: Refer to Figures 1-4A crane inspection protection device shown in the figure includes a fixing plate 7 and a bottom column 1 that supports the fixing plate 7. A sliding groove 8 is provided inside the fixing plate 7, and a sliding slot 9 is provided on the inner side surface of the sliding groove 8. A slider 11 is slidably connected to the inner side surface of the sliding groove 8. A plurality of grooves 19 are provided on both sides of the inner wall of the sliding groove 8, and a limiting component is arranged in the grooves 19; the limiting component includes a spring 20 arranged in the groove 19, a limiting block 10 is slidably connected to the inner side surface of the groove 19, the side surface of the limiting block 10 is trapezoidal, and both ends of the spring 20 are fixedly connected to the limiting block 10 and the inner side surface of the groove 19 respectively. A fixing ring 24 is fixedly connected to the side surface of the slider 11, and a buckle 6 is arranged on the outer side of the fixing ring 24. Through the cooperation of the limiting block 10 of the slider 11, the corresponding limiting block 10 can stably support the slider 11 at a suitable position, without manually hanging the safety lock at different positions, the operation is simple, and it is more convenient and safe; a fixing block 12 is fixedly connected to the outer side of the slider 11, a slot hole 22 is provided inside the fixing block 12, and a sliding frame 14 is slidably connected to the inner side surface of the slot hole 22, which is convenient for the sliding of the sliding frame 14 and avoids the situation of deviation during the sliding of the sliding frame 14; a bottom plate 21 is fixedly connected to the outer side of the sliding frame 14, and a seat plate 15 is fixedly connected to the top of the bottom plate 21, which is convenient for the staff to sit on the seat plate 15 to rest and avoid the situation of arm fatigue and falling; a fixing frame 16 is fixedly connected to the outer side of the sliding frame 14, a screw hole 17 is provided inside the fixing frame 16, a screw rod 18 is threadedly connected to the inner side surface of the screw hole 17, and a threaded hole 13 adapted to the screw rod 18 is provided on the outer side of the fixing block 12, which is convenient for fixing the positions of the fixing frame 16 and the sliding frame 14.
