In order to achieve the purpose, the utility model adopts the following technical scheme:
the multifunctional object hanging hole cover plate comprises two bottom frames and two side covers, one ends of the two bottom frames are respectively and rotatably connected to the upper side and the lower side of the object hanging hole, stop blocks are respectively fixed to the left side and the right side of the object hanging hole, and the other ends of the two bottom frames can be respectively supported on the stop blocks; one end of each of the two side covers is rotatably connected to the left side and the right side of the object hanging hole respectively, and the two side covers are positioned on the upper layers of the two bottom frames respectively; when the two side covers and the two bottom frames cover the object hanging holes respectively, the two side covers and the two bottom frames close the object hanging holes; when two side covers and two underframe found respectively, adjacent side cover and underframe link into an integrated entity through dismantling the connecting piece between to form the protection rail around hanging the thing hole.
Further, the detachable connecting piece is a bolt.
Further, the middle part of underframe has the apron, and the both sides of underframe are hollow out construction, and the apron is the protruding structure that makes progress, and when the side cover lid was on the underframe, apron top and side cover top parallel and level.
Furthermore, a handle is arranged at the top of the side cover.
Furthermore, a hand-pulling chain is connected to the bottom frame.
By adopting the technical scheme, the utility model has the following beneficial technical effects:
1. the hanging hole cover plate is designed to be a permanent device connected with the hanging hole, so that the hanging hole cover plate does not need to be hung down by a bridge crane every time of use, and the use is safer;
2. the object hanging hole cover plate is in a closed state when covered, the function of the cover plate is achieved, the two side covers and the two bottom frames form a protective fence when erected respectively, the use is flexible, and the functions are diversified;
3. the opening and closing of the object hanging hole cover plate only needs to be completed through manual operation, the use is convenient, and the working efficiency is high.
Drawings
The utility model is described in further detail below with reference to the accompanying drawings and the detailed description;
FIG. 1 is a schematic view of the cover of the present invention shown open;
FIG. 2 is a schematic view of the cover half-closed of the present invention;
fig. 3 is a schematic view of the cover plate of the present invention fully closed.
Detailed Description
As shown in fig. 1-3, the multifunctional object hanging hole cover plate of the present invention comprises two bottom frames 1 and two side covers 2, wherein one end of each of the two bottom frames 1 is rotatably connected to the upper and lower sides of the object hanging hole, the left and right sides of the object hanging hole are respectively fixed with a stop block 3, and the other end of each of the two bottom frames 1 can be respectively supported on the stop block 3; one end of each of the two side covers 2 is rotatably connected to the left side and the right side of the object hanging hole respectively, and the two side covers 2 are positioned on the upper layers of the two bottom frames 1 respectively; when the two side covers 2 and the two bottom frames 1 cover the object hanging hole respectively, the two side covers 2 and the two bottom frames 1 close the object hanging hole; when two side covers 2 and two underframe 1 stand up respectively, link into an integrated entity through dismantling the connecting piece between adjacent side cover 2 and the underframe 1 to form the protection rail around hanging the thing hole.
Wherein, the detachable connecting piece is a bolt.
Preferably, the middle part of the bottom frame 1 is provided with a cover plate 11, the two sides of the bottom frame 1 are hollow structures 12, the cover plate 11 is an upward protruding structure, and when the side cover 2 covers the bottom frame 1, the top of the cover plate 11 is flush with the top of the side cover 2.
In order to conveniently and manually pull up the side cover 2 and the bottom frame 1, a handle 21 is arranged at the top of the side cover 2, and a hand chain 4 is connected to the bottom frame 1.
The using method of the utility model comprises the following steps: when the device of the hanging hole cover plate 11 needs to be opened, 2 workers stand at the two ends of the hanging hole to open the side covers 2 at the two sides firstly, then stand at the upper side and the lower side of the hanging hole to pull up the two bottom frames 1 by using one side of the handle chain 4 together, and insert the side covers 2 at the two sides by using the bolts on the bottom frames 1 to form a # -shaped protective fence without installing a temporary fence.
