According to the construction experience of steel construction box bridge, the bridge segment is dispatched from the factory before, need reserve the interim manhole of certain quantity at the bridge floor, inside in order to be ready for operating personnel to get into the segment through the manhole, mend the lacquer, operations such as welding, in the correlation technique, operating personnel can be around the manhole with the fix with screw steel sheet, when preventing that large-scale material from falling into the manhole, also prevent that operating personnel from stepping on the sky injured, but this kind of mode can't prevent that less object from falling into the manhole, also can't prevent that sleet from getting into the manhole simultaneously, thereby make the operating personnel's that gets into the bridge segment through the manhole work can receive the influence of environment and weather.

In view of the above problems, an embodiment of the present invention discloses a protective structure 101, as shown in fig. 1 to 2, the protective structure 101 includes a frame 102 and a moving member 104, the frame 102 is provided with a through hole 103, and the moving member 104 can move relative to the through hole 103 to close the through hole 103 or move away from the through hole 103. When an operator needs to enter the bridge segment 202, the through hole 103 is aligned to the manhole 201 on the bridge segment 202, so that the through hole 103 covers the manhole 201, at the moment, when the moving member 104 moves to close the through hole 103, the manhole 201 can be closed through the protective structure 101 and the moving member 104, the purpose of protecting the operator in the bridge segment 202 is achieved, the operation of the operator in the bridge segment 202 cannot be influenced by external weather (wind, rain, snow and the like) and environment (falling objects, personnel treading on the air and the like), and the operation safety and stability of the operator are ensured. When an operator in the bridge segment 202 needs to ventilate, the moving member 104 can be moved so that the moving member 104 is removed from the through hole 103, thereby achieving the effect of ventilating the operator in the segment.

It will be appreciated that the protective structure 101 may also comprise a fan, whereby the interior space of the auxiliary bridge section 202 is ventilated when the through hole 103 is open.

Specifically, as shown in fig. 2 to 5, the protection structure 101 includes a plurality of moving elements 104, a plurality of racks 205 are disposed on the driving element 203, each rack 205 corresponds to one rotating shaft 204, one rotating shaft 204 drives one moving element 104 to move, when all rotating shafts 204 are driven to rotate by the driving element 203, each rotating shaft 204 corresponds to one more moving element 104, so that all moving elements 104 can jointly seal the through hole 103, and prevent falling objects or rain and snow from entering the manhole 201, or all moving elements 104 no longer seal the through hole 103, so that the through hole 103 is communicated with the outside, and ventilate for an operator inside the bridge segment 202.

Specifically, the moving parts 104 on the protective structure 101 are sequentially arranged adjacently, as shown in fig. 6, two adjacent moving parts 104 are set, one of the two adjacent moving parts is a first moving part 601, the other is a second moving part 602, a first notch 603 is arranged on one side of the first moving part 601 close to the second moving part 602, a second notch 604 is arranged on one side of the second moving part 602 close to the first moving part 601, when the first moving part 601 and the second moving part 602 both seal the through hole 103, the first notch 603 and the second notch 604 can be buckled with each other, thereby ensuring that the first moving part 601 and the second moving part 602 can seal the through hole 103 with relatively closed.

It can be understood that each moving part 104 is provided with a first notch 603 and a second notch 604, and the first notch 603 and the second notch 604 are respectively located at two ends of the moving part 104, so that all the moving parts 104 can be connected with each other in a relatively closed manner.

Specifically, the protective structure 101 further includes an electromagnet, a battery 208, and a switch structure, where the battery 208 may supply power to the electromagnet, and the electromagnet may be connected to the battery 208 through the switch structure, so that whether the battery 208 powers the electromagnet may be controlled through the switch structure. The electromagnet is located on one side, used for being attached to the bridge section 202, of the frame body 102, when the protective structure 101 needs to be used, the protective structure 101 is firstly placed above the bridge section 202, the through hole 103 of the protective structure 101 is aligned to the manhole 201 and covers the manhole 201, then the switch structure is opened, the battery 208 is enabled to electrify the electromagnet, at the moment, the electromagnet can be adsorbed on the bridge section 202 (made of steel), connection of the protective structure 101 and the bridge section 202 is completed, when the protective structure 101 does not need to be used, the protective structure 101 can be separated from the bridge section 202 only by closing the switch structure, and therefore the protective structure 101 can be used for multiple times.

Specifically, the switch structure comprises an inner switch 207 and an outer switch, the inner switch 207 and the outer switch can independently control whether the battery 208 supplies power to the electromagnet, and the outer switch is located on the outer surface of the frame body 102, so that an operator located on the outer surfaces of the bridge segment 202 and the frame body 102 can turn on or off the electromagnet through the outer switch, and connection and separation of the protective structure 101 and the bridge are completed; the inner switch 207 is located on the inner surface of the frame body 102 (when the moving member 104 closes the through hole 103, the surface of the frame body 102 located in the space formed by the frame body 102 and the bridge segment 202 belongs to the inner surface of the frame body 102), which enables an operator located in the manhole 201 to control the working state of the electromagnet through the inner switch 207, thereby controlling the connection and disconnection of the protection structure 101 and the bridge segment 202.

The method of use of the above structure is that when an operator needs to enter the interior of the bridge section 202 for repair painting or welding, the protective structure 101 is first placed near the manhole 201 (in which case the protective structure 101 does not cover the manhole 201), then the operator enters the interior of the bridge section 202 through the manhole 201, then the operator extends the upper body out of the manhole 201 to the outside of the bridge section 202, and then the protective structure 101 is lifted by arms. With the gradual entering of operating personnel manhole 201, operating personnel can cover protective structure 101 on manhole 201 gradually, after the whole of operating personnel's health got into manhole 201, protective structure 101 just in time was placed on manhole 201, at this moment, operating personnel can pass through internal switch 207 for battery 208 energizes for the electro-magnet, makes protective structure 101 be connected with bridge segment 202, and then operating personnel can also drive moving member 104 through the second pushing piece and seal through-hole 103, thereby guarantee the operating safety and the stability of operating personnel who is located bridge segment 202, make it not influenced by environment and weather. During operation, an operator can move the moving element 104 by moving the second pushing element to ventilate the inside of the people hole 201. After the operation is completed, the operator can power off the electromagnet through the inner switch 207, at this time, the protection structure 101 is separated from the bridge structure, and the operator can move the protection structure 101 away from the manhole 201 and then move the protection structure out of the bridge from the manhole 201.

It will be appreciated that the protective structure 101 also serves to prevent others from falling out of the manhole 201 into the interior of the bridge section 202.

It will be appreciated that during the above operation, other persons may also move the moving member 104 via the first pushing member 206 to ventilate the interior of the bridge section 202, and may also control the electromagnet via the external switch to facilitate the movement of the shielding structure 101.
