Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1 to 5, the utility model discloses a building site elevator well head protector of first embodiment, including rectangular frame 1, be provided with a plurality of vertical poles 11 in the rectangular frame 1, and a plurality of vertical poles 11 set up side by side, vertical pole has strengthened rectangular frame's fastness like this. The width of the rectangular frame body 1 is greater than that of the elevator shaft opening 2; when the rectangular frame body 1 is arranged on the inner side of the elevator shaft opening 2, and constructors need to move the upper part or the lower part of the rectangular frame body, the width of the rectangular frame body is larger than that of the elevator shaft opening, so that the rectangular frame body cannot swing up and down; thereby improving safety. The bottom of the front face of the rectangular frame body 1 is provided with a warning board 12, so that warning stripes can be seen at night, the middle of the front face of the rectangular frame body 1 is provided with an identification board 13, and words of 'elevator well mouth, attention safety' can be written on the identification board 13. A support plate 14 is transversely arranged in the middle of the back of the rectangular frame body 1, the support plate 14 is fixedly connected with the plurality of vertical rods 11, and the length of the support plate 14 is greater than the width of the rectangular frame body 1; thus, the two ends of the supporting plate can be clamped on the clamping pieces 3 of the supporting plate; the scissors wall 21 inboard of elevator well head 2 is provided with two backup pad fasteners 3, backup pad fastener 3 includes vertical board 31 and "L" shape limiting plate 32, vertical board 31 is fixed in on the scissors wall 21, "L" shape limiting plate 32 is connected with vertical board 31 bottom is perpendicular, the outside perk of terminal 321 of "L" shape limiting plate 32, the inboard of "L" shape limiting plate 32 is provided with a bellying 322, both ends are provided with concave part 141 about backup pad 14, concave part 141 and bellying 322 phase-match, and the backup pad card is in vertical inboard like this, and the bellying of "L" shape limiting plate 32 can carry out the block operation to the backup pad for the backup pad is difficult for removing on the backup pad fastener, thereby has improved the security.
