Embodiment Construction
[0044] In order to describe in a simple manner, the folding guardrail and the folding cover according to the present invention will be described simultaneously with the same drawings.
[0045] exist figure 1 Among them, for the convenience of observation, the building floor is omitted, and the folding guardrail includes two symmetrically arranged folding cover plates 11 and two symmetrically arranged fences 12 . figure 1 The foldable guardrail in is fully opened. If the foldable cover plates 11 are closed, the two foldable cover plates 11 can completely cover the equipment lifting opening. Two symmetrically arranged fences 12 can freely undulate conveniently. Both the folding cover 11 and the fence 12 are arranged on the frame 13 . The frame 13 should be widely understood, and it can be understood as any supporting device suitable for being arranged at the equipment hoisting opening. figure 2 shown figure 1 The folding guardrail in is closed. The two foldable cover plat...

The invention discloses a foldable cover plate and foldable guardrail. The foldable guardrail includes the foldable cover plate; the foldable cover plate is arranged on the equipment hatch of a building floor; the surrounding of the equipment hatch is provided with a supporting framework; the invention is characterized by including a first cover plate, a second cover plate, supporting parts arranged at the two sides of the second cover plate, as well as a counter weight connected with the four connection part of the second cover plate. The first cover plate is provided with a first connectionpart and a second connection part; the second connection part and the first connection part are opposite; the first connection part used for connecting the supporting framework can rotate along a first axis relative to the supporting framework; the second cover plate is provided with a third connection part and a fourth connection part; the fourth connection part and the third connection part areopposite; the third connection part is connected with the second connection part of the first cover plate; the second cover plate can rotate along a second axis relative to the first cover plate; thesecond axis is parallel with the first axis; the supporting parts are arranged between the third connection part and the fourth connection part; the counter weight is connected with the four connection part of the second cover plate so as to lead the centers of gravity of the second cover plate and the counter weight to be at one side of the supporting part near the fourth connection part.
Description
technical field [0001] The invention relates to a cover plate and a guardrail arranged on an equipment hoisting opening of a building floor. Background technique [0002] On the equipment hoisting opening of the building floor of the power plant, there must be a gearbox at the connection between the support frame and the cover plate, and the larger the cover plate, the larger the gearbox and the more, the space is not effectively used, and the effective opening is much smaller than the actual opening. . [0003] Due to structural limitations, the erected height of the cover plate is determined by the opening, so it is difficult to ensure the height of the guardrail. [0004] When the opening is large, the cover plate will be relatively high, and the equipment must be hoisted higher when hoisting the equipment, so the hoisting of the equipment has certain requirements on the height of the floor. Therefore speaking from this point of view, the prior art just cannot make a co...
