[0001] The utility model belongs to the technical field of elevator construction, in particular to an elevator steel structure well frame. Background Art

[0002] With the development of society and the needs of an aging population, the functions of existing residential buildings need to be improved and the addition of elevators is a supplement to the original vertical transportation system.

[0003] The Chinese utility model patent with publication number CN108821057A discloses an elevator steel structure derrick, comprising four longitudinal beams and a plurality of transverse beams connected to the four longitudinal beams; each longitudinal beam comprises a plurality of connecting segments connected in sequence, and adjacent connecting segments are connected by a first screw; each transverse beam is connected to the longitudinal beam by a second screw, the surface of the first screw being flush with the surface of the longitudinal beam, and the surface of the second screw being flush with the surface of the transverse beam; the longitudinal beams and the transverse beams are respectively made of square tubes. Adjacent connecting segments are connected by the first screw, and the required number of connecting segments can be provided according to actual use needs; the surface of the first screw is flush with the surface of the longitudinal beam, and the surface of the second screw is flush with the surface of the transverse beam. In this way, the surface of the elevator steel structure derrick is flush and has no protrusions, which facilitates the painting of the entire surface of the elevator steel structure derrick; in this way, the connecting segments and transverse beams can be mass-produced and stored, reducing the production cost of the elevator steel structure derrick.

[0004] However, the above-mentioned comparative documents have the following technical problems:

[0005] First, when installing and erecting a crossbeam between two adjacent columns in the above-mentioned device, there is no leveling device for the crossbeam. Therefore, when installing the crossbeam, manual leveling is usually performed to ensure the horizontality of the crossbeam during installation, thereby ensuring the structural strength of the subsequent overall steel structure derrick. However, this method requires manual participation before each erection of the crossbeam to ensure the level of the crossbeam, which greatly increases the labor workload and is inconvenient for the installation and erection of the above-mentioned device.

[0006] Second, the bottom of the beam in the above device lacks a supporting mechanism. As a result, after the above device is used for a long time, the ends of the beam and the columns will become loose, and the surface of the beam will deform after being subjected to pressure, affecting the supporting effect of the beam, which is not conducive to the long-term use of the above device.

The second locking bolt 34, whose threaded end passes through the fixing hole on one side, passes through the strip groove 121, and comes out from the fixing hole on the other side, and a second locking nut 35 is threadedly connected to its threaded end.

[0046] Specifically, the opening size of the second accommodating groove 33 and the thickness transition of the end of the angle steel 12 are matched, so that when the second fixing block 32 is installed, it can be clamped on the outside of the end of the angle steel 12 through the second accommodating groove 33, further ensuring the stability of the second fixing block 32 during installation and the tightness of the connection between it and the end of the angle steel 12, preventing subsequent loosening or falling.
