Description

Lifting platform for building construction Technical Field The application belongs to the technical field of building construction equipment, and particularly relates to a building construction lifting platform. Background Building construction lift platforms, commonly referred to as building lifts, are vertical transport devices used for man-carrying cargo during building construction. The equipment is generally attached to the outer side of a main structure of a building and is arranged in parallel with the vertical face of the building so as to realize vertical transportation of materials and up-and-down passing of constructors. Because the traditional building is mostly of a vertical structure, the construction lifter is usually vertically installed, a guide rail frame of the construction lifter is fixed in a vertical direction, and the angle is not adjustable. The design forms a standardized production and installation mode in long-term practice, and can meet the construction requirements of most conventional buildings. However, with the continued development of modern architectural design concepts and the increasing diversity of building forms, the facades of many buildings exhibit different angled configurations in order to pursue aesthetic effects and differentiated appearance. Such non-vertical building forms place new adaptability demands on the construction hoist attached to its outside. Traditional perpendicular installation formula lift is because of its guide rail frame angle is fixed, can't laminate the building surface of slope, leads to the installation difficulty, adheres to unstably, exists the potential safety hazard even. To solve this contradiction, at present, a customized production mode is generally adopted in the industry, namely, a lifter with a corresponding angle is specially manufactured according to the inclination angle of a specific building. Although the customization scheme can meet the construction requirement, the customization scheme has the obvious defects that the customization relates to redesign of main structures such as a chassis, a suspension cage, a guardrail, a wall-attached support and the like due to different inclination angles of different buildings, the cost is high, the customization cannot be commonly used among different projects, and resource waste and repeated investment are caused. Disclosure of Invention Based on the technical problems, the application provides a lifting platform for building construction, which solves the technical problems that the lifting platform in the prior art does not have angle adjusting capability and cannot adapt to various inclined building outer facades. In order to achieve the purpose, the technical scheme adopted by the application is that the building construction lifting platform comprises: The support assembly comprises a guide rail frame and a wall-attached support, wherein the guide rail frame is arranged parallel to the outer wall of the building, and the wall-attached support is connected between the outer wall of the building and the guide rail frame; The lifting cage comprises a lower frame body, an upper frame body, at least four upright posts and a connecting rod unit, wherein the upper frame body and the lower frame body are of square frame structures which are horizontally arranged, at least four upright posts are connected to the corner positions of the upper frame body and the lower frame body in a one-to-one correspondence manner, the tops of the upright posts are hinged with the upper frame body, the bottoms of the upright posts are hinged with the lower frame body, the hinge shafts of the upright posts are parallel to each other, the connecting rod unit is connected between the upper frame body and the lower frame body in a telescopic manner, two side faces which define the lifting cage to be perpendicular to the hinge shaft line of the upright posts are first side faces, two side faces which are parallel to the hinge shaft line of the upright posts are second side faces, and The traveling assembly is arranged on the first side face of the suspension cage and used for driving the suspension cage to move along the guide rail frame. In one possible implementation, the support assembly further includes: A fixed seat with an arc-shaped track, a bottom of the guide rail frame is in sliding fit with the track, and And the hydraulic oil cylinder is arranged on the fixed seat and used for driving the guide rail frame to slide along the track.
