Description

Technical Field

[0001] This utility model relates to the field of safety equipment technology, specifically to a safety attachment point and protective device. Background Technology

[0002] When working in areas such as aircraft maintenance, maintenance of the top of some equipment, and glass curtain walls, the edges of some equipment and facilities at high altitudes are smooth and have no other protruding structural devices, or the structures are there but cannot be installed with anchor points. The only way to provide fall protection is to use aerial ladder trucks. However, due to the height and angle limitations of aerial ladder trucks, the operation is inconvenient and the protection area is incomplete. In some cases, the area is too high or the site structure is too limited to provide any fall protection. Moreover, some areas cannot provide anchor points, which poses a great risk of falling.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] like Figures 1-2The safety attachment point and protective device shown includes a support housing 1, a suction cup structure 2 is provided below the support housing 1, the suction cup structure 2 and the adsorption surface 3 form a suction cup chamber 4, a rotatable hanging arm 5 is provided above the support housing 1, the hanging arm 5 is provided with a buckle 51 for suspending a safety belt, the suction cup chamber 4 is made to have a negative pressure inside by a suction device 6, so that the suction cup structure 2 and the adsorption surface 3 are tightly fixed. In order to reduce weight, the support housing 1 has a cavity 11, which is connected to the suction cup chamber 4. A pressure gauge 7 is provided on the support housing 1 for observing the pressure of the suction cup chamber 4, and an air pipe connector 111 is provided on the side of the cavity 11, which can control the opening and closing of the air pipe.

[0023] like Figure 3 As shown, this is the first embodiment of the present invention. The suction device 6 is external and is located outside the cavity 11. It includes a vacuum pump 62 driven by a power supply 61. One end of the vacuum pump 62 is connected to the air pipe 63, and the other end of the air pipe 63 is connected to the air pipe connector 111 and connected to the suction cup chamber 4. The vacuum pump 62 draws air from the suction cup chamber 4 to create a negative pressure inside it.

[0024] like Figure 4 As shown, this is the second embodiment of the present invention. The suction device 6 is built-in and located inside the cavity 11. The power supply 61 and the vacuum pump 62 are also located inside the cavity 11. The air pipe 63 is a three-way pipe connecting the air pipe connector 111, the vacuum pump 62, and the suction cup chamber 4. When the hanging point device itself needs to be evacuated, the air pipe connector 111 is adjusted to be in the closed state. The vacuum pump 62 can draw air from the suction cup chamber 4 through the air pipe 63 to create a negative pressure inside. When it is necessary to evacuate other safety hanging point devices, the air pipe connector 111 can be connected to another air pipe to evacuate other safety hanging point devices without the need to carry an additional suction device 6. At this time, the safety hanging point is the suction device 6.

[0025] like Figure 5 The aforementioned is a protective device, including at least two safety attachment points located on the same horizontal line. The two safety attachment points are connected by a safety rope. When working, personnel can attach their safety belts to the safety rope 8 to achieve the protective function.

[0026] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention. The technical content for which protection is sought in the present invention has been fully described in the claims.
