Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an elevator steel structure gallery device. Background Art

[0002] Old residential buildings are generally not equipped with elevators. With the development of society, more and more residents of old buildings require the installation of outdoor elevators for the convenience of their lives. In real life, land is separated on one side of the building to build the elevator shaft, a passage is opened on the outer wall of the building, and then an aerial corridor bridge is built between the elevator shaft and the passage. When installing the corridor bridge on site, electric welding is generally used to weld the corridor bridge to the elevator shaft. Although it is simple, fast and low-cost, the corridor bridge and the elevator shaft become one after welding, which makes it impossible to adjust the position relationship with the elevator shaft. Especially when the angle and orientation between the corridor bridge and the shaft need to be adjusted during the later installation and maintenance, the two need to be cut and separated and adjusted before being fixed, which increases the difficulty of construction and increases the cost. Therefore, the existing technology for installing the corridor bridge has the disadvantages of being difficult to install and not being able to effectively adjust the position relationship between the corridor bridge and the elevator shaft.

[0003] A Chinese patent discloses an elevator gallery bridge with an adjustment function (authorization announcement number CN209384361U). The patented technology uses a high-strength bolt assembly to connect the two, which is easy to install and disassemble. At the same time, the verticality of the elevator shaft is adjusted by the cooperation of the gallery bridge and the elevator shaft. There is no need to spend separate time and manpower to solve the installation angle and orientation problems of the gallery bridge and the elevator shaft in the later stage. Therefore, the practical problem that the existing technology does not have the ability to effectively adjust the position relationship between the gallery bridge and the elevator shaft during the installation of the gallery bridge is solved;

[0004] However, it has certain disadvantages: the vibrations generated when residents walk on the walkway of the corridor bridge will be transmitted to the surface of the adjusting bolts. Over time, the adjusting bolts will rotate due to the vibrations, causing them to loosen, thereby affecting the stability of the entire corridor bridge. Utility Model Content
