detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Referring to a foldable elevator shaft operating platform shown in Figures 1 to 5, it includes a main frame, the main frame includes an adjustable length outer frame, and the outer frame is composed of a first outer frame part and a second outer frame The square pipe of the second outer frame part is inserted and positioned on the square pipe of the first outer frame part, and is positioned by the positioning pin, and two connecting rods are connected between the first outer frame parts A square pipe, a support frame is connected below the main frame, a clamping column 10 is connected below the support frame, and a thick steel plate 11 is laid on the top of the main frame.

When the utility model is in use, the process is as follows. First, the outer frame is adjusted according to the size of the elevator wellhead. If the elevator wellhead is relatively large, the second outer frame part is pulled out from the first outer frame part, and then positioned by positioning pins. After the frame is adjusted, the extension of the support frame behind the clamping column 10 and the clamping column 10 are placed on the concrete platform of the next floor, and the outer frame is lapped on the concrete platform of the previous floor. Finally, the thick steel plate 11 Laying on the main frame, due to the support of the outer frame and connecting square pipes, the operator can step on it for construction. At the same time, after the construction is completed, the operation platform is easy to disassemble and transport. Of course, the outer frame of the present invention can also be stretched and shrunk at both ends.

Further, the support frame includes a slanted frame 9, the slanted frame 9 is connected to the first outer frame part through a hinge 12, the middle part of the slanted frame 9 is also fixed with a first stand 8, the The first stand 8 is connected with the outer frame by bolts. That is to say, after the construction is completed, the support frame can be folded through the hinge 12, so that the volume of the entire operating platform is smaller. Specifically, the support frame of the present utility model is detachably connected by the first stand 8 and the outer frame. Yes, so when folding, the first stand 8 and the outer frame need to be disassembled first.

Further, the middle part of the two connecting square pipes is also connected with a reinforced square pipe, and the second vertical stand 7 is connected to the bottom of the connecting square pipe, and the first stand 8 passes through the second stand 7 and The outer frames are connected. In order to make it more convenient and quick to connect the support frame to the outer frame, a second stand 7 is also connected below the connecting square tube of the outer frame, and the second stand 7 and the first stand 8 are connected by bolts.

Further, one side of the thick steel plate 11 is also connected with an extended side plate 13 through a hinge 12 . That is to say, if the length of the outer frame becomes longer, the length of the thick steel plate 11 can also be lengthened by directly expanding the side plate 13 . Certainly, if the outer frame of the present invention adopts the method that both ends can be stretched and contracted, then as shown in FIG. 5 , two expansion side panels 13 need to be provided.

Further, several groups of round holes 14 are provided in the middle of the thick steel plate 11, and a U-shaped bolt 6 is matched in each group of round holes 14, and each U-shaped bolt 6 passes through a group of round holes 14 and connects the square pipe , and fixed by nuts. In order to be more convenient in transportation, the utility model is provided with several groups of round holes 14 in the middle of the thick steel plate 11, and is provided with several U-shaped bolts 6, so it can be hoisted by hoisting equipment, which greatly increases convenience.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included in the Within the protection scope of the present utility model.
