This also leads to the following two risks in the existing inspection mode:
[0004] (1) The inspection method using a crane hanging a hanging basket causes personnel to be in a shaking state during the operation, resulting in inconvenient operation and risks such as falling objects from high altitude;
[0005] (2) The crane has a limited travel range and there are risks such as the hook wire rope derailing and the basket tilting at a large angle. Utility Model Content

[0008] Furthermore, a mounting hole is provided on the semicircular clamp.
[0009] Furthermore, the safety device also includes a reinforcement plate, which is connected to the semicircular clamp and the pedal.
[0010] The beneficial effects of the technical solution provided by the embodiment of the utility model include at least: a safety device applied to the vertical rod of the swing rod, including a semicircular clamp, a connecting bolt and a pedal, the two ends of the semicircular clamp are provided with a connecting part, the connecting part is provided with a connecting hole, the two semicircular clamps are arranged oppositely, so that the connecting holes on the two semicircular clamps are located oppositely; the connecting bolt is passed through the connecting hole, and the two ends of the connecting bolt are provided with an adjusting nut; the pedal is connected to the semicircular clamp.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.
[0019] Refer to the following Figure 1 to Figure 2 A safety device provided according to some embodiments of the present invention is described.
[0020] like Figure 1 and Figure 2 As shown, according to an embodiment of the utility model, a safety device provided for sleeve installation on the vertical rod of the swing rod can be used for inspection and maintenance of the bearings at the segmented connection of the vertical rod of the swing rod. The safety device includes a semicircular clamp 1, a connecting bolt 4 and a pedal 6. The two ends of the semicircular clamp 1 are provided with a connecting portion 2, and the connecting portion 2 is provided with a connecting hole 3. The two semicircular clamps 1 are arranged relative to each other, so that the whole formed by the two semicircular clamps 1 can be sleeved on the vertical rod of the swing rod, and the connecting holes 3 located on the two semicircular clamps 1 are located relative to each other. The connecting bolt 4 is inserted into the connecting hole 3, and the two ends of the connecting bolt 4 are screwed with an adjusting nut 5, so that the adjusting nut 5 can adjust the size of the whole formed by the two semicircular clamps 1, so as to be fixed to the vertical rod of the swing rod of different models, and prevent the semicircular clamp 1 from sliding on the vertical rod of the swing rod. The pedal 6 is welded to one side of the semicircular clamp 1, and is used to provide a fulcrum when the staff inspects the bearing. Therefore, the safety device can effectively replace the method of inspecting bearings through a hanging basket, solve the problem of having no fulcrum when adjusting the height of the swing arm, facilitate the staff to operate in a fixed position, and improve safety.
[0021] Specifically, in the use state, two semicircular clamps 1 are fixed in parallel to the bearing position of the segmented connection of the vertical rod of the swing arm, and the staff can inspect the bearing by stepping on the pedal 6 without using tools such as a hanging basket, thereby reducing costs. By adjusting the connecting bolts 4 and the adjusting nuts 5, the safety device can be fixed to different height positions of the vertical rod of the swing arm, which is easy to operate and can be freely adjusted.
[0022] Among them, the pedal 6 is preferably made of thickened steel plate, and after actual testing, the load-bearing capacity exceeds 100 kilograms.
[0023] In addition to inspecting the bearings, the safety device can also be used to adjust the height of the vertical rod of the swing arm.
[0024] like Figure 2 As shown, a mounting hole 7 is provided on the parallel surface of the semicircular clamp 1 in the vertical direction for installing an anti-fall rope to ensure the safety of the workers.
[0025] like Figure 1 As shown, the safety device further comprises a reinforcing plate 8 for reinforcing the connection between the pedal 6 and the semicircular hoop 1, thereby improving the load-bearing capacity of the pedal 6. Preferably, the reinforcing plate 8 is made of angle steel and welded to the semicircular hoop 1 and the pedal 6.
