Detailed Description

To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.

Referring to fig. 1 to 4, the present embodiment provides an anti-falling device for a guide wheel 3, including a seat plate 1, a rotating shaft, a main bolt 2 and a guide wheel 3. The rotating shaft 4 includes a first screw hole and a second screw hole, the first screw hole and the second screw hole are disposed on two opposite surfaces of the rotating shaft, and generally, the first screw hole and the second screw hole are disposed on a plane of the rotating shaft. The main bolt 2 penetrates through the seat plate 1 and is connected into the first screw hole. It should be noted that a screw hole is also provided in the seat plate 1 so that the main bolt 2 can pass through, and the anti-drop safety plate 5 is also applied in the same way. The guide wheel 3 is sleeved on the rotating shaft 4, and the guide wheel 3 is used for rotating by taking the rotating shaft 4 as an axis. The wheel surface of the guide wheel 3 can be used as a contact surface with the rope in the construction hoist. The anti-falling device of the guide wheel 3 also comprises an anti-falling safety plate 5 and an auxiliary bolt 6. The auxiliary bolt 6 penetrates through the anti-falling safety plate 5 and is connected into the second screw hole. The falling-off prevention safety plate 5 is further connected with the seat plate 1, so that the falling-off prevention safety plate 5 is more stable.

In the prior art, one side of the guide wheel 3 is fixed by the main bolt 2, and the other side of the guide wheel 3 is fixed without a fixing device, so that the guide wheel 3 is easy to fall off from the other side of the guide wheel 3, and the structure is as shown in fig. 1. The guide wheel 3 that drops has potential safety hazard, and the personnel or the equipment that can injure the below when the guide wheel 3 falls. According to the technical scheme, the anti-falling safety plate 5 and the auxiliary bolt 6 are designed at the other side of the guide wheel 3, if the guide wheel 3 falls off from the rotating shaft 4, the guide wheel 3 can be hung by the anti-falling safety plate 5 and the auxiliary bolt 6, and people or equipment below the guide wheel 3 are prevented from being injured by the collision. 3 dropout prevention means of guide pulley has improved guide pulley 3's factor of safety under the prerequisite that does not influence 3 rotations of guide pulley, has guaranteed personal safety or property safety, has positive meaning.

In this embodiment, the guide wheels 3 are provided in plurality, and the fall-off prevention plate 5 is provided between the guide wheels 3 and the heads of the sub bolts 6. As an example, the guide wheel 3 can be two, three or even more. The structure of the two guide wheels is shown in fig. 2, 3 and 4. The guide wheels 3 are respectively connected to the seat plate 1 through a rotating shaft 4, and the anti-falling safety plate 5 is arranged outside each guide wheel 3. Therefore, when each guide wheel 3 is to be separated from the rotating shaft 4, the guide wheels can be hung by the anti-falling safety plate 5, and potential safety hazards caused by falling of the guide wheels 3 are avoided.

In the present embodiment, since the guide wheels have a certain width, there is a certain distance between the fall-off prevention guard and the seat plate, so the fall-off prevention guard 5 is designed to include a recessed portion 51 and a non-recessed portion, the non-recessed portion is located at the side wall of the guide wheel 3, the recessed portion 51 is located between the plurality of guide wheels, the recessed portion 51 is closer to the seat plate than the non-recessed portion, and the structure is shown in fig. 3.
