Safety construction platform for machine-room-less elevator shaft

Abstract

The invention discloses a safety construction platform for a machine-room-less elevator shaft. The safety construction platform for the machine-room-less elevator shaft comprises a beam structure, a plate structure and a support. The beam structure is obliquely erected in the elevator shaft, the bottom end of the beam structure is fixedly connected with the elevator shaft, and the top end of the beam structure abuts against the shaft wall of the elevator shaft; the plate structure is movably connected with the beam structure, and the plate structure can rotate around the joint of the plate structure and the beam structure; the plate structure is overturned upwards, and the support is used for supporting the plate structure, so that the plate structure forms a construction platform for people to stand on in the elevator shaft; and the support can also be detached, and the plate structure is put down. Compared with a traditional scaffold building platform, according to the safety construction platform for the machine-room-less elevator shaft provided by the invention, a large amount of manpower, material resources and time are saved; and the building operation can be directly carried out on the top layer of the elevator shaft, so that the efficiency is greatly improved. According to the safety construction platform provided by the invention, the plate structure is movably connected with the beam structure, the plate structure is overturned upwards, the bottom of the plate structure is supported by the support, and then the construction platform for people to stand on can be formed in an elevator shaft, so that construction operation and building are extremely rapid and convenient.

Description

technical field [0001] The invention belongs to the technical field of elevator construction auxiliary equipment, and in particular relates to a safe construction platform for an elevator shaft without a machine room. Background technique [0002] Machine room-less elevators refer to elevators that do not require buildings to provide closed special machine rooms for installing elevator drive hosts, control cabinets, speed limiters and other equipment. In order to save space, the machine room-less elevator installed the control cabinet, main engine, speed limiter and other equipment in the machine room above the hoistway instead of the machine room, and canceled the special machine room setting, effectively improving the utilization rate of the building area while reducing construction cost. [0003] In the installation process of machine room-less elevators, it is often necessary to install hanging points and hanging beams in the top floor of the elevator shaft. In the tra...

Problems solved by technology

[0007] This invention can directly use the door opening of the elevator shaft to erect, and its structure is simpler than that of the previous invention, but the staff still need to build a scaffolding working platform on the two suspended I-beams, which poses a threat to the personal safety of the construction staff. greater threat
