Abstract
A double-door hanging hole cover plate comprises a bottom plate, wherein a hanging hole is formed in the center of the bottom plate, lower cover plates are symmetrically mounted on two sides of the bottom plate through lower cover plate supports, upper cover plates are symmetrically mounted on the other two sides of the bottom plate through upper cover plate supports, and the heights of rotating shafts of the upper cover plate supports are larger than those of rotating shafts of the lower cover plate supports. The double-door hanging hole cover plate provided by the utility model has the advantages that the upper cover plates and the lower cover plates on the two layers are closed under normal conditions to serve as bearing components to plug the hanging hole on a base; and after the upper and the lower cover plates are opened, the hanging hole is unplugged, and the upper and the lower plates are connected through bolts to form a fence with a corresponding height around the hanging hole, so as to achieve high safety, simplicity of operation and convenience of opening. The upper and the lower cover plates can be manually opened and reset before and after construction, so that a bridge crane is no more used, and the working performance is further greatly improved.
Description
Technical field
The utility model relates to the cover plate that hangs the thing hole in a kind of hydroelectric power plant factory building, and particularly a kind of double door hangs the thing blind patch.
Background technology
Hanging the thing blind patch in the existing hydroelectric power plant factory building, all is to adopt integral body or distinguish prefabricated section flat-faced tube structure or all steel frame body plan panel type structure.This cover plate need hang out cover plate when object lifts by crane with the bridge machine, install the scaffold fence then around hanging the thing hole.When particularly the bottom object need lift by crane, just have the multilayer cover plate to open, having needs to set up fence around the multilayer hole, and object lifting at this moment needs to consume great amount of manpower and time to lift by crane cover plate and set up fence.Simultaneously, after completion, the fence dismounting, cover plate resets and also consumes a lot of activity durations.Particularly between the turn(a)round in winter, also need to take the bridge machine, influence the maintenance progress of a lot of scope of operations in the power station.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of double door and hangs the thing blind patch, can open cover plate easily, and the cover plate after opening can be formed fence.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of double door hangs the thing blind patch, comprise base plate, the base plate center is provided with hangs the thing hole, lower cover is installed in the base plate both sides by lower cover bearing symmetry, and upper cover plate is installed in the other both sides of base plate by upper cover plate bearing symmetry;
The height that upper cover plate props up seat rotating axis is higher than the height that lower cover props up seat rotating axis.
It is semicircle that the base of upper cover plate becomes.
It is semicircle that the lower cover leg becomes.
Under opening, connect by latch between upper cover plate and the adjacent lower cover.
Described upper cover plate and lower cover are provided with opens handle.
Described base plate has spacing stage.
A kind of double door that the utility model provides hangs the thing blind patch, by double-deck upper and lower cover plate is set, under normal circumstances, cover plate is closed up and down, the thing hole is hung in shutoff on base as load-supporting part, after having opened upper and lower cover plate, hang the thing hole and open, the levels cover plate connects by latch simultaneously, hanging the fence that the thing hole forms corresponding height all around, fool proof, simple to operate, it is convenient to open.Before and after the construction operation, the unlatching of upper and lower cover plate and reset and all can adopt manpower does not re-use the bridge machine, has improved operating efficiency greatly.
Simultaneously upper and lower cover plate overlaps and forms well cabinet frame structure when closing, and bearing capacity is big; Upper and lower cover plate is all detachable.When lifting article height superelevation, need when hanging in, a side upper cover plate or the lower cover of this one side can be removed, and other three faces still use as firm safe fence, after lifting operation is finished, in that being installed to reset, upper cover plate or lower cover get final product.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the vertical view of the utility model closed condition.
Fig. 2 is the vertical view that the fence state was opened and formed to the utility model.
Fig. 3 is the front view that the fence state was opened and formed to the utility model.
Fig. 4 is the lateral view that the fence state was opened and formed to the utility model.
The specific embodiment
In Fig. 1-Fig. 4, a kind of double door hangs the thing blind patch, comprises base plate 1, and base plate 1 center is provided with hangs thing hole 7, and lower cover 4 is installed in base plate 1 both sides by lower cover bearing 6 symmetries, and upper cover plate 2 is installed in the other both sides of base plate 1 by upper cover plate bearing 3 symmetries;
The height of upper cover plate bearing 3 axis of rotation is higher than the height of lower cover bearing 6 axis of rotation.The height that exceeds should add 1/2nd of upper cover plate thickness greater than the radius sum of two axis of rotation, thereby guarantees that upper cover plate 2 and lower cover 4 can fold mutually when closing.When upper cover plate bearing 3 and lower cover bearing 6 are set, to note avoiding forming and interfere.
It is semicircle that the base of upper cover plate 2 becomes, thereby avoid base and base plate 1 to interfere.
It is semicircle that lower cover 4 legs become, thereby avoid leg and base plate 1 to interfere.
Under opening, connect by latch 5 between upper cover plate 2 and the adjacent lower cover 4.In Fig. 2, latch 5 is positioned at the inboard of upper cover plate 2 and lower cover 4, and latch 5 also can be arranged on the outside of upper cover plate 2 and lower cover 4.
Described upper cover plate 2 and lower cover 4 are provided with opens handle.
Described base plate 1 has spacing stage 8, and the position that stage 8 can limit base plate 1 is set, and avoids mobile, has also strengthened braced structures simultaneously, is beneficial to load-bearing.Hang the shape in thing hole by transformation, for example hang the stage shape that the thing hole is set to three grades, after the utility model is packed into, can make upper cover plate 2 concordant, thereby be beneficial to passing through of personnel and equipment with ground.
