It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
The invention provides an elevator shaft construction platform as shown in fig. 1-4, which comprises a rotating shaft 10, a first supporting frame 20 and a second supporting frame 30 which are rotatably connected on the rotating shaft 10, and a first platform 40 arranged on the first supporting frame 20, wherein the first platform 40 protrudes out of the first supporting frame 20 and covers the second supporting frame 30, and a plurality of supporting legs 50 are arranged at one ends of the first supporting frame and the second supporting frame, which are far away from the rotating shaft 10. The first platform 40 is provided with a plurality of lifting lugs 41. The rotation shaft 10 may be disposed at a central bottom of the first platform 40, the first support frame 20, the second support frame 30, and the first platform 40 may be made of steel, and the first platform 40 may be welded to the first support frame 20. The first platform 40 includes a first platform frame 42 and a steel plate disposed on the first platform frame 42, wherein the steel plate may be a patterned steel plate, and has a non-slip function. The legs 50 project from the first and second support frames as fulcrums for connection to the hoistway.
Specifically, the landing leg overlap joint of first braced frame 20 is on the floor of elevartor shaft door opening, and the landing leg of second braced frame 30 then stretches into and reserves the mounting groove in the lateral wall relative with the door opening in, makes the contained angle between first, the second braced frame stretched into 180, because first platform 40 protrusion first braced frame 20 and cover second braced frame 30, play limiting displacement to the rotation of second braced frame 30, under the action of gravity of construction platform self and load, form the stable platform that can supply the construction, as shown in fig. 3. When the lifting hook needs to be moved to the next floor, as shown in fig. 4, the lifting hook is hung on the lifting lug 41 by adopting a tower crane or a crane arranged at the top of the elevator shaft, the first supporting frame 20 and the first platform 40 incline to the left side of the lifting lug 41 under the action of gravity, the second supporting frame 30 inclines to the right side of the lifting lug 41, along with the rising of the lifting hook, the supporting leg 50 is separated from a floor slab and a mounting groove, the included angle between the first supporting frame and the second supporting frame is reduced, the size of the construction platform is reduced, the construction platform can be completely accommodated in the elevator shaft, and other floors can be smoothly moved.
A limiting device is further arranged between the second supporting frame 30 and the first supporting frame 20, and the limiting device is used for limiting the rotation amplitude of the second supporting frame, further limiting the distance between the second supporting frame and the side wall of the elevator shaft, and avoiding that the second supporting frame is too far away from the side wall of the elevator shaft when being hoisted, which is not beneficial to installation. In this embodiment, the limiting device is an expansion link 70 with two ends respectively rotatably connected to the bottoms of the first and second supporting frames, the expansion link 70 can be an electric expansion link with a remote control function, when the elevator car is hoisted, the expansion link 70 is controlled to slowly retract, so that the second supporting frame 30 is prevented from rotating to cause excessive shaking, and the first and second supporting frames and the distance between the supporting legs and the elevator car wall are controlled to avoid too long distance; when the support is installed, the telescopic rod 70 is controlled to extend, so that the second support frame 30 is tightly attached to the first platform 40, and the support legs 50 can be inserted into the installation grooves with the aid of a crane; when the construction platform is used, the limiting device can also play a role in stabilizing the structure.
The bottom of the supporting leg 50 of the first supporting frame 20 is also provided with a supporting leg 51, the supporting leg 51 and the supporting leg 50 form an L-shaped structure which can be clamped at the edge of a floor slab of an elevator shaft door opening to prevent the supporting leg 50 of the construction platform from escaping from a mounting groove reserved on the side wall of the elevator shaft.
Further, the construction platform further includes a reinforcing means including reinforcing bolts that screw-connect the first platform 40 and the second support frame 30. Specifically, the first platform frame 42 and the second supporting frame 30 may include a plurality of beams, and threaded holes may be formed in the two corresponding beams, so that reinforcing bolts may be driven into the threaded holes after the construction platform is installed, thereby enhancing the stability of the construction platform.
Preferably, the legs 50 are provided with chamfers to facilitate insertion into the mounting slots.
Preferably, the end of the supporting leg 50 is also provided with a roller to avoid the collision of the supporting leg 50 with the elevator shaft wall during hoisting.
Example 2
The invention provides an elevator shaft construction platform, which is different from the embodiment 1 in that a limiting device is a steel wire rope 60 connected between one end of a first platform 40 far away from a first supporting frame 20 and one end of a second supporting frame 30 far away from a rotating shaft 10, and a support leg 51 is arranged at the bottom of a support leg 50 of the second supporting frame 30, as shown in figure 5, the support leg of the second supporting frame 30 is lapped on a door opening floor slab, and the support leg of the first supporting frame 20 is lapped in a mounting groove reserved on the wall of an elevator shaft. When the construction is carried out, the constructor pulls the second support frame 30 to the first platform 40 by using the wire rope 60, and the whole construction platform forms a plate shape after the two are attached, so that the supporting legs can be inserted into the installation grooves more easily.
Example 3
The invention provides an elevator shaft construction platform, which is different from the embodiment 1 in that a second supporting frame 30 is further provided with a second platform 80, the first platform and the second platform are in a straight shape and are parallel, and the second platform 80 protrudes out of the second supporting frame 30 and covers a first supporting frame 20, as shown in fig. 6. Compared with embodiment 1, the size of the first platform 40 is reduced, and the center of gravity during hoisting is easier to control.
