Description

Technical Field

[0001] The utility model relates to the technical field of elevator equipment, and particularly relates to a counterweight side bracket assembly for an elevator. Background Technique

[0002] An elevator is an indispensable device in modern buildings. The installation and fixation of the elevator are extremely important for the safe and stable operation of the elevator. Most elevators are equipped with counterweights. The existing installation positions of the counterweights on the elevator are divided into side-mounted and rear-mounted. Generally, the counterweight is rear-mounted for passenger elevators with machine rooms, but in special cases, the counterweight can also be side-mounted. Generally, the side-mounted counterweight is for machine-roomless passenger elevators, sightseeing elevators, freight elevators, and medical elevators. Since the size between the hoistway wall and the elevator car changes according to the size during the hoistway civil engineering, the elevator car and the hoistway wall are fixed through the cooperation of the car guide rail and the guide rail bracket. Then, when the counterweight is side-mounted and in a limited space, it is necessary to install the counterweight guide rail of the counterweight well as the car guide rail of the elevator car, and it is necessary to meet the requirements of convenient installation, good strength, and convenient obstacle avoidance. All the above problems need to be solved urgently.

[0003] Although there are many types of existing side-mounted counterweight brackets, during the actual installation process, due to the flatness of the hoistway wall and small errors during the installation process, it is very difficult to adjust the horizontal flatness of the side-mounted counterweight bracket and correct the dimensional deviation that occurs during the installation process through the structural design of the existing side-mounted counterweight bracket.

[0004] To sum up, the existing elevator counterweight side bracket has technical problems that it is difficult to balance the structural strength, installation convenience, and adjustable adaptability of the structure. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that the elevator counterweight side bracket has technical problems that it is difficult to balance the structural strength, installation convenience, and adjustable adaptability of the structure.

[0006] To solve the above problems, the utility model provides an elevator counterweight side bracket assembly, which includes two horizontal bracket components arranged in parallel and at a preset distance apart. Two side counterweight guide rails and a main counterweight guide rail are respectively connected between the two horizontal bracket components. The horizontal bracket component includes a cross beam for installing the elevator car guide rail and side brackets respectively fixedly connected to both ends of the cross beam. The side bracket includes a wall surface fixing part and a guide rail installation part in a right-angled shape, which are respectively used for connecting with the hoistway wall and the side counterweight guide rail on the corresponding side. The guide rail installation part is connected to the end of the cross beam, and the cross beam and the guide rail installation parts connected to both ends of it are perpendicular to each other to form a C shape.

[0007] The counterweight side support assembly of the utility model includes a transverse support assembly and a guide rail member that are connected to form a semi-cage-shaped frame. The transverse support assembly includes two groups and is spaced at a preset height. The main body is a cross beam, and its two ends are fixedly connected to side supports. The side supports are respectively connected to the side counterweight guide rail and the elevator shaft wall surface through a right-angled structure. Through such a structure, the installation between the counterweight side guide rail and the wall surface can be transformed from a linear fit to a point-like fit, which can more easily avoid obstacles and adapt to the unevenness of the wall surface. Moreover, due to the reduction of the guide rail connection area, when the guide rail needs to be finely adjusted relative to the support, there are fewer positions that need to be disassembled and adjusted, which improves the adaptability and adjustment performance of the support assembly. In addition, through such a semi-cage-shaped structure, a good supporting effect on the guide rail member can be provided, ensuring the strength of the structure, and having the advantages of simple structure and convenient installation, effectively solving the technical problem that it is difficult to balance the structural strength, installation convenience, and adaptability and adjustability of the existing elevator counterweight side support.

The cross beam uses a common C-shaped channel steel, and integral flanging structures are added to the edges on both sides. Through this structure, the bending and torsional resistance of the steel beam are further increased. On this basis, a reinforcing cross plate along the length direction of the cross beam is welded and fixed in the middle section of the flanging structure of the cross beam to further improve the strength of the steel beam.

[0009] As a preferred solution, the cross beam and the main counterweight guide rail are adjustably connected through a right-angle mounting member.
