[0002] With the continuous improvement of people's living standards, the concept of residents is changed, and the demand for installing elevators in old buildings is large. For residents living in high-rise buildings, especially for the elderly, this will be a major change. Installing elevators can well solve the time they need to go up and down the stairs. It is impossible to design an elevator shaft in the original old building. Therefore, we can only complete this project outside the old building. Some outdoor shafts generally use steel structure wellhead, which is covered with protective plates, simple structure, practical and economical.

[0019] The present utility model is further described below in combination with the accompanying drawings and specific implementation:

[0020] As Figs. 1 to 4 shown in the figure, the embodiment of the present utility model preferably provides a stable structure of an elevator steel frame, which comprises a top frame 1 and four columns 2, and an installation space for installing an elevator shaft is formed between the top frame 1 and the four columns 2, characterized in that a connecting beam 6 is arranged between adjacent columns 2, and a limiting assembly is arranged between the column 2 and the connecting beam 6; wherein the limiting assembly comprises a first limiting block 21 horizontally and telescopically arranged on the side wall of the column 2, a driving member 22 for driving the first limiting block 21 to protrude outwardly from the side wall of the column 2, and a second limiting block 23 telescopically arranged on the end of the connecting beam 6, the first limiting block 21 is recessed on the side away from the column 2 and has a first limiting groove 24, one end of the connecting beam 6 is embedded in the first limiting groove 24, the lower side of the first limiting groove 24 is a guide slope 25, and the upper side of the first limiting groove 24 is recessed and has a second limiting groove 26 capable of being embedded in the second limiting block 23, and the guide slope 25 can abut against the lower end of the second limiting block 23 to cause the upper end of the second limiting block 23 to be embedded in the second limiting groove 26.

[0021] Specifically, the driving member in the limiting assembly drives the first limiting block to protrude outwardly from the column in a connected state, and then the first limiting groove of the first limiting block and the connecting beam remain in an embedded connected state, and at this time, the second limiting block in the connecting beam is resisted by the guide slope of the first limiting groove, causing the second limiting block to move upward relative to the connecting beam and be embedded in the second limiting groove in the first limiting groove, thereby achieving complete limiting of the first limiting block and the connecting beam, thereby effectively avoiding the risk of the connecting beam directly falling and causing injury when the bolt connecting the connecting beam and the column is loose.

[0022] Further, the column 2 has a first cavity 3 with one side opening, the first cavity 3 has a vertically arranged screw rod 27, the driving member 22 is threadedly fitted on the screw rod 27, the lower side of the driving member 22 is a circumferentially inclined guide cone surface 28, the guide cone surface 28 abuts against one end of the first limiting block 21, and a spring 29 is arranged between the inner side of the first cavity 3 and the first limiting block 21 to cause one end of the first limiting block 21 to tightly abut against the guide cone surface 28.

[0023] ​Specifically, in the initial state, the first limiting block is kept in the retracted state relative to the column by the elastic force of the spring, and at this time, one end of the first limiting block is in abutting connection with the guide cone surface of the driving member. When the connecting beam is displaced and the end is positioned at the first limiting groove of the first limiting block, the driving member is screwed down along the screw rod, and the guide cone surface on the driving member abuts against one end of the first limiting block, thereby driving the first limiting block to displace relative to the column through the guidance of the guide cone surface, and keeping the first limiting block in the connected state of protruding outward from the side wall of the column. The first limiting groove of the first limiting block is kept in the embedded state with the connecting beam, and the second limiting block is kept in the embedded state in the second limiting groove through the guide slope of the first limiting groove, thereby achieving the firm connection between the connecting beam and the column. Then, the connecting bolts can be installed between the connecting beam and the column to make the connection between the connecting beam and the column more firm.

[0025] Specifically, the column can be formed by bending a steel plate to effectively save the material and processing cost of the column. The first cavity is formed in the inner side of the column, and a plurality of first reinforcing rib plates are vertically spaced and welded in the first cavity to effectively ensure the structural strength of the column formed by bending the steel plate. The connecting beam is connected between the connecting plates of different columns by bolts, and the connecting beam effectively achieves the mutual locking between adjacent columns.

A plurality of first reinforcing rib plates 7 are vertically spaced in the first cavity 3. The connecting beam 6 is detachably connected between adjacent connecting plates 4 of different columns 2 by bolts, and the connecting beam 6 is detachably connected to the inner side wall of the installation cavity 5 by bolts.

[0027] Further, the top frame 1 and the connecting beam 6 are detachably connected by bolts with a plurality of second reinforcing rib plates 11 and a plurality of third reinforcing rib plates 12, the length direction of the second reinforcing rib plates 11 and the length direction of the third reinforcing rib plates 12 are 90 degrees.
