The base 11 and the upwardly facing top of the surrounding seat 12 jointly form an upwardly facing blocking surface 6, and each perforation group 14 has two upper and lower corresponding perforations 141.

The body 1 is specifically an inflatable air cushion composed of the base 11 and the surrounding seat 12, the diameter of the base 11 is greater than the diameter of the surrounding seat 12, and the distance between the base 11 and the surrounding seat 12 Connect with each other. Since the main body 1 needs to be placed in a high-temperature environment, both the base 11 and the surrounding seat 12 need to have high heat resistance. The base 11 is covered with the outer coating 16, and the surrounding seat 12 itself It is made of heat-resistant material. The outer coating layer 16 can resist high temperature and prevent the air cushion structure covered inside from being damaged by high temperature. In this embodiment, the outer coating 16 is a protective film made of polyvinyl chloride (PVC) with a temperature resistance of 100°C. It can also be made of polyimide (PI) or polyethylene (PE)... It is made of other materials, but it is not limited by this.

The inner diameter of the feeding channel 13 of the main body 1 is equal to the inner diameter of the opening 912 of the furnace body 91. The feeding channel 13 is used to transport materials required for maintenance or construction. It can also be implemented together without affecting the construction progress. Each perforation group 14 is arranged at equal intervals and is connected with each corresponding hanging member 22. In this embodiment, the method in which the rope is directly wound and tied to each perforation group 14 is taken as an example, but it is not limited to its number, arrangement position, and shape, and can also be adjusted as required, as long as the main body 1 can be stably It only needs to be hung inside the furnace body 91, and it is not limited to the above description.

The inflating unit 3 includes a blower 31 for generating power to introduce air into the body 1, and an inflator 32 connecting the blower 31 and the air inlet 15 of the body 1. The blower 31 can fill the inside of the body 1 with gas, or extract gas from the body 1 in the reverse direction. The inflation tube 32 is a flexible flexible tube body, which facilitates the configuration of the matching path and facilitates the implementation of the inflation operation.

Referring to Figures 4 and 5 and in conjunction with Figure 3, when installing this embodiment, one end of each hanger 22 is first positioned on the fixing frame 21, and then the other end is wound around each corresponding perforation The assembly 14 is connected to the air inlet 15 of the main body 1 with the inflation tube 32. At this time, the main body 1 is in an uninflated state. Then the body 1 is hoisted from the opening 912 of the furnace body 91 into a predetermined installation area inside the furnace body 91, and the blower 31 of the inflating unit 3 can be turned on to perform the inflating operation. After the inflating operation is completed, the main body 1 Expand from the uninflated state to an inflated state, and the base 11 will surround and abut against the inner edge of the furnace body 91, and the blocking surface 6 formed together with the surrounding base 12 prevents falling from above the body 1 A falling object 7 of the body 1 is prevented from being injured by the falling object 7 for maintenance personnel located under the main body 1.

It should be noted here that the height of the top surface of the surrounding seat 12 is higher than the height of the top surface of the base 11 mainly because when the falling object 7 falls onto the body 1, there will be a rebound force to make the falling object 7 bounces to other places and there is a risk of falling into the feeding channel 13, and then increase the height of the surrounding seat 12 to block the falling object 7 after rebounding, so as to ensure that the falling object 7 will not come from the feeding channel 13 fell and injured the maintenance personnel. When the present embodiment is to be dismantled after the maintenance work is completed, the blower 31 of the inflating unit 3 only needs to operate in the reverse direction to extract the gas inside the body 1, so that the body 1 is changed from the inflated state to the uninflated state, and then The main body 1 is lifted from the furnace body 91 from the opening 912 and stored, and it can be used for the next maintenance project.

In summary, the embodiment of the new type of suspension protection device uses the base 11 and the surrounding seat 12 to define and form the blocking surface 6 and the feeding channel 13, so as to block falling objects 7 from above. Moreover, the required materials can be transported through the feeding channel 13, and the existing furnace body 91 can be matched to complete the installation without modification and design, and the furnace body 91 itself will not be damaged. Therefore, it can indeed achieve the purpose of cost and new style.
