Description

Technical Field

[0001] The utility model relates to the field of building construction engineering, in particular to an elevator shaft opening protection device. Background Art

[0002] In current construction, standardized protection or steel pipes are often used as protection for elevator shaft openings. However, standardized protection cannot achieve full enclosure (during the elevator installation process, in order to ensure the safety of installers in the shaft, the elevator shaft opening must be fully enclosed to prevent falling objects), and steel pipe protection cannot be easily moved (when installing the elevator, the protection needs to be frequently moved and opened to facilitate the installation of elevator doors, tracks and other components).

[0003] Therefore, it is necessary to develop a protective device that can fully enclose the elevator entrance and is easy to move. Utility Model Content

[0004] The utility model aims to overcome the defects of the prior art and provide an elevator opening protection device to solve the problem that the existing protection device cannot take into account both full closure and easy movement at the same time.

[0005] The utility model provides an elevator shaft opening protection device, and its technical solution is as follows: it comprises: a protection plate arranged at the elevator shaft opening; at least two U-shaped handles movably arranged on the protection plate, and the ends of the U-shaped handles are tightly attached to the inner wall of the elevator shaft opening.

[0006] Furthermore, the U-shaped handle includes: a sliding rod; a fixed rod fixed at one end of the sliding rod, the fixed rod being in close contact with the inner wall of the elevator shaft opening; and a hand-held rod fixed at one end of the sliding rod away from the fixed rod.

[0007] Furthermore, the protective plate is provided with a semicircular guide ring, the guide ring is fixed on the guide rail to form a closed circular ring, and the sliding rod is located in the circular ring formed between the guide ring and the guide rail.

[0008] Furthermore, a semicircular guide ring is provided on the protective plate, and the guide ring cooperates with the guide rail.

[0009] Furthermore, the protective plate includes: a protective frame and a protective net, and the protective net is fixed to the inner wall of the protective frame.

[0010] Furthermore, the protective plate includes an upper protective plate and a lower protective plate, and the upper protective plate and the lower protective plate are hinged.

[0011] Furthermore, the upper protective plate and the lower protective plate are hinged via a hinge.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By setting a protective plate and a U-shaped handle, the protective plate can protect the elevator shaft opening. At the same time, the design of the U-shaped handle can abut against the inner wall of the elevator shaft opening, thereby fixing the protective plate. The device is simple to operate, highly practical, convenient to disassemble and assemble, and has good protective effect.

[0014] By setting a hinged upper protective plate and a lower protective plate, when the device is in a non-use state or a moving state, the upper protective plate and the lower protective plate can be folded in half, thereby reducing the occupied space and facilitating movement and storage.

[0015] This device is made of common materials at the construction site such as waste steel bars, is convenient to use, has a high utilization rate, can be recycled and reused, and conforms to the concept of green construction. Brief Description of the Drawings
