Technical Field
[0001] The utility model relates to the technical field of elevator shaft operation frames, and particularly relates to an integrally liftable elevator shaft operation frame. Background Technique
[0002] In the elevator shaft, in order to facilitate the operation of workers and solve the problems of vertical and horizontal transportation, it is necessary to set up an elevator shaft construction operation frame (platform), mainly for construction workers to go up and down to work, for plastering and painting the elevator shaft, equipment installation, etc. In order to ensure the safety of construction operations in the elevator shaft, reduce the material use cost, and improve work efficiency, it is worthwhile to optimize and improve the structure and installation of the elevator shaft operation frame (platform).
[0003] The methods for setting up the elevator shaft operation frame usually include: segmental cantilever, elevator shaft steel platform, and automatic elevator shaft steel platform. The commonly used methods for setting up the elevator shaft operation frame are cumbersome, with high construction costs, and time-consuming and laborious for turnover after the operation frame is set up. There are also many potential safety hazards during the installation and removal process. Content of the Utility Model
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an integrally liftable elevator shaft operation frame.
[0005] The purpose of the utility model is achieved through the following technical solutions:

The cross-shaped main beams are fixed in the base frame, and the secondary beams are fixed in the "mouth"-shaped frame formed by the cross-shaped main beams. Support feet are provided at the four corners of the base frame. The support feet include support steel plates and clamping groove plates. The clamping groove plates are L-shaped. One side edge of the clamping groove plate is fixed on the base frame, and the other side edge forms a clamping groove with the base frame. The support steel plates are fixed on the base frame through fixed shafts. One end of the support steel plate is clamped into the clamping groove, and the other end extends out of the base frame as a support plate. The support steel plate can rotate around the fixed shaft as the rotation center.
[0007] Columns are fixed at the intersection points of the above-mentioned cross-shaped main beams, and steel pipes are used to reinforce and stabilize between the columns. The columns are divided into several operation layers.
[0008] Pedals are set around the operation layers of the above-mentioned columns. Support rods and cross beams are provided below the pedals. The other end of the support rods is fixed on the cross beams, and the other end is fixed on the pedals.
[0009] Ladders are provided between the above-mentioned operation layers, and safety rings are provided on each layer of columns.
[0010] Pulleys are installed at the top ends of the above-mentioned support plates.

[0012] The beneficial effects of the present utility model are as follows:
[0013] The present utility model is welded by channel steel and corresponding square steel, with stable structure and high strength. The connection of each component has obvious advantages in terms of tidiness and stability compared with the conventional method of using fasteners for erection. During the use process, mechanical lifting is mainly used, reducing manual labor and having better safety. The base of the operation frame is equipped with support feet, which are placed in the reserved holes of the shear wall of the elevator shaft. It can be lifted along with the construction floor. When the support feet reach the reserved holes, they can be automatically clamped, which is convenient for lifting. Compared with the traditional method of erecting the frame layer by layer, the working efficiency is greatly improved. Due to the setting of the support feet, only one set of standardized lifting operation frames needs to be configured for one shaft, saving costs. BRIEF DESCRIPTION OF THE DRAWINGS

SPECIFIC EMBODIMENTS
[0020] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.
[0021] Refer to Figures 1-5 , the present utility model provides a technical solution:
[0022] An integrally liftable elevator shaft operating frame, comprising a base. The base consists of a base frame 1, a cross-shaped main beam 2 and secondary beams 3. The cross-shaped main beam 2 is fixed in the base frame 1, and the secondary beams 3 are fixed in the "mouth"-shaped frame formed by the cross-shaped main beam 2. Support feet 5 are provided at the four corners of the base frame 1. Columns 7 are fixed at the intersection points of the cross-shaped main beam 2, and steel pipes are used to reinforce and stabilize between the columns 7. The elevator shaft operating frame is divided into three operating layers. A lifting ring 4 is provided at the top layer to facilitate the lifting of the elevator shaft operating frame; pedals 10 are set up around the columns 7 on the second and third layers. Support rods 9 are provided below the pedals 10, and the other ends of the support rods 9 are fixed on the cross beams 11. Ladders 12 are provided between layers, and safety rings 8 for hanging safety ropes are provided on each column 7.
[0023] The support foot 5 includes a support steel plate 51 and a clamping groove plate 52. The clamping groove plate 52 is L-shaped. One side of the clamping groove plate 52 is fixed on the base frame 1 through a fastening bolt 56. The other side of the clamping groove plate 52 and the base frame 1 form a clamping groove. The support steel plate 51 is fixed on the base frame 1 through a fixed shaft 53. One end of the support steel plate 51 is clamped into the clamping groove, and the other end extends outside the base frame 1 as a support plate. The support steel plate 51 can rotate around the fixed shaft 53 as the rotation center, and a pulley 55 is installed at the top end of the support plate.
[0024] A reinforcing column 6 is installed on the base frame 1 behind the support foot 5, and a reinforcing plate 54 is installed on the clamping groove plate 52. One end of the reinforcing plate 54 is fixed on the clamping groove plate 52, and the other end is fixed on the reinforcing column 6.
[0025] Lifting principle of the elevator shaft operating frame:
[0026] When the elevator shaft operating frame needs to move from one working site to the next working site, the hoist is connected to the lifting ring 4 to lift the elevator shaft operating frame upward. During the lifting process, the support steel plate 51 rotates counterclockwise around the fixed shaft 53. After leaving the reserved hole on the wall, a certain angle is formed between the support steel plate 51 and the base frame 1. The pulley 55 slides on the wall until it reaches the reserved hole at the next working site. Under the action of the self-gravity of the elevator shaft operating frame, the support steel plate 51 rotates clockwise around the fixed shaft 53 to the horizontal and is clamped into the reserved hole again.
[0027] The above are only the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge in related fields. And any changes and modifications made by those skilled in the art without departing from the spirit and scope of the present invention should fall within the protection scope of the appended claims of the present invention.
