[0022] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1: As Figures 1 - 5As shown in the figure, the utility model provides a construction operation frame for a building elevator shaft, including: a support frame 1, a top plate 3 is fixedly connected to the top of the support frame 1, an installation frame 8 is fixedly connected to the bottom of the top plate 3 near the center position, a threaded rod 15 is rotatably connected to the center position of the left surface of the installation frame 8, a contact plate 7 is threadedly connected to the outer surface of the threaded rod 15, a first bevel gear 9 is fixedly connected to the outer surface of the threaded rod 15 near the left side, an avoidance groove 11 is opened on the top of the top plate 3, a movable rod 14 is installed on the inner surface of the avoidance groove 11 through a bearing, a second bevel gear 10 is fixedly connected to the bottom of the movable rod 14, the position of the first bevel gear 9 is matched with the position of the second bevel gear 10, and the outer surface of the first bevel gear 9 is meshed with the outer surface of the second bevel gear 10. Symmetrically fixed blocks 6 are fixedly connected to the top of the support frame 1 near the left side, guide rods 12 are fixedly connected to the right surfaces of the two fixed blocks 6, the left end faces of the two guide rods 12 are fixedly connected to the right surface of the installation frame 8, both of the two guide rods 12 penetrate through the contact plate 7 movably, a turning handle 13 is fixedly connected to the top of the movable rod 14, a plurality of hanging rings 4 are fixedly connected to the top of the top plate 3, and two limiting frames 2 are fixedly connected to the right surface of the support frame 1 near the bottom position.

[0025] The effect achieved by the entire embodiment 1 is that during use, the hanging rings 4 on the top plate 3 are connected by the hook on the crane, the top plate 3 is hoisted from the top of the elevator shaft by the crane and slowly placed at the required floor position. Then, after the staff fits the sides and bottom of the support frame 1 and the limiting frame 2 to the floor surface, the movable rod 14 is rotated through the turning handle 13, so that the second bevel gear 10 rotates, thereby synchronously driving the first bevel gear 9 to rotate. Through the rotation of the first bevel gear 9, the threaded rod 15 will rotate on the installation frame 8. At the same time, with the cooperation of the guide rod 12, the contact plate 7 continuously moves outward, so that the contact plate 7 fits with the shear wall of the elevator shaft, thereby limiting and fixing the top plate 3 inside the elevator shaft through the contact plate 7 and the limiting frame 2, and then the hook is removed for use. When the height of the top plate 3 needs to be adjusted, the hook is connected to the hanging ring 4, and then the turning handle 13 is rotated in the reverse direction, so that the contact plate 7 no longer contacts and fits with the shear wall, and the limiting frame 2 and the support frame 1 are separated from the floor surface, so that the position of the top plate 3 can be adjusted inside the elevator shaft. When contacting, only by rotating the turning handle 13 on the top plate 3 can the contact plate 7 be made to contact or separate, which is more convenient. Moreover, by using the threaded rod 15 to adjust the contact plate 7, a smoother adjustment range can be provided, allowing the contact plate 7 to be finely adjusted within a larger range to meet diverse usage requirements.

[0026] Embodiment 2: As Figures 1 - 5 shown, a cover plate 5 is hinged to the top of the support frame 1, the position of the cover plate 5 is matched with the position of the avoidance groove 11, and the turning handle 13 is located inside the avoidance groove 11.

[0027] The effect achieved by the entire Embodiment 2 is that the handlebar 13 can be accommodated through the avoidance groove 11, preventing accidental contact with the handlebar 13 by workers when working on the top plate 3, which may cause loosening. At the same time, the avoidance groove 11 can be sealed by the cover plate 5 to further protect the handlebar 13.

[0028] Working principle: During use, the hanging ring 4 on the top plate 3 is connected by a hook on the crane. The top plate 3 is hoisted into the elevator shaft from the top by the crane and slowly placed at the required floor position. Then, after the side and bottom of the support frame 1 and the limiting frame 2 are fitted to the floor surface, the cover plate 5 is opened to expose the handlebar 13. Then, the handlebar 13 is rotated to rotate the movable rod 14, causing the second bevel gear 10 to rotate, which in turn drives the first bevel gear 9 to rotate synchronously. The rotation of the first bevel gear 9 drives the threaded rod 15 to rotate on the mounting bracket 8. At the same time, with the cooperation of the guide rod 12, the contact plate 7 continuously moves outward, causing the contact plate 7 to fit against the shear wall of the elevator shaft. Thus, the top plate 3 is limited and fixed inside the elevator shaft by the contact plate 7 and the limiting frame 2. Only by rotating the handlebar 13 on the top plate 3 can the contact plate 7 be made to contact or disengage, which is relatively convenient. Moreover, the contact plate 7 can be adjusted by the threaded rod 15, providing a smoother adjustment range and allowing the contact plate 7 to be finely adjusted within a larger range to meet diverse usage requirements.

[0029] The above is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as the technical solution content of the present invention is not departed from, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
