Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and in particular to a protective device for elevator shaft construction. Background Technology

[0002] During the construction process, especially in the construction phase of elevator shafts in high-rise buildings, ensuring the safety of construction workers is of paramount importance. As an important structural part of the building, the construction environment of elevator shafts often presents high safety risks, especially in the elevator doorway area, where the large opening can easily become a potential hazard point for accidents. Therefore, it is particularly important to design a simple, practical, and effective elevator shaft construction safety protection device.

[0003] Traditional elevator shaft construction protection methods typically involve using simple wooden boards or steel plates for temporary shielding. However, this method has drawbacks such as insecure fixing, easy detachment, and ineffective warning, making it difficult to effectively prevent construction accidents. Furthermore, the temporary shielding boards or steel plates are placed on the outside of the elevator shaft, which can affect the construction of the elevator door opening side walls, such as plastering or tiling. In addition, with the continuous improvement of building safety regulations and the increasing demands for construction safety, traditional protection methods are no longer sufficient to meet the needs of modern building construction.

[0004] Based on this, the applicant proposed a construction protection device for elevator shafts to solve the above technical problems. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a protective device for elevator shaft construction.

[0006] This utility model is solved by the following technical solution:

[0007] An elevator shaft construction protection device includes symmetrically installed slots on the inner side of the elevator shaft at the lower end of the elevator door opening. A protective plate is snapped onto the slot, and the upper end of the protective plate is fixed to the inner side of the elevator shaft by a pin.

[0008] Preferably, the pins are symmetrically arranged on the protective plate.

[0009] Preferably, the pin includes a pin seat fixedly installed on the upper part of the back of the protective plate, and a mounting plate is correspondingly provided on the inner side of the elevator shaft. A plug rod is movably connected to the mounting plate through two limit seats, and the plug rod is connected to the pin seat.

[0010] Preferably, the insertion rod is also provided with a handle, which is located between the two limiting seats.

[0011] Preferably, the mounting plate is further provided with a locking ring, and the handle is provided with a through hole, the locking ring passing through the through hole restricting the movement of the insertion rod.

[0012] Preferably, a warning sign is provided on the front of the protective plate.

[0013] Preferably, the protective plate has a warning pattern on its front side.

[0014] Preferably, it also includes a padlock, wherein after the locking ring passes through the through hole, the padlock is attached to the locking ring to prevent the handle from disengaging.

[0015] Preferably, the slot is detachably fixed to the wall inside the elevator shaft by screws.

[0016] Preferably, the mounting plate is detachably fixed to the wall inside the elevator shaft by screws.

[0017] Preferably, the pin holder is fixedly mounted on the protective plate by screws or welding.

[0018] The beneficial effects of this utility model are as follows:

[0019] First, the protective device uses a slot and pin structure to enable the rapid installation and fixation of the protective plate inside the elevator shaft, thus avoiding the problems of insecure fixing and easy detachment in traditional methods. This stable fixing method ensures that the protective plate will not fall off or shift during construction, effectively preventing construction accidents and ensuring the safety of construction personnel.

[0020] Secondly, the design of installing the protective plate inside the elevator shaft not only ensures the safety of construction workers, but also avoids affecting the construction of the elevator door opening side wall. This protective device allows construction workers to carry out normal construction operations on the door opening side wall, improving construction efficiency.

[0021] In addition, the protective device also has a good warning effect. The protective plate can be set with obvious warning slogans or patterns to remind construction workers to pay attention to safety and further reduce the risk of construction accidents.

[0022] Finally, the protective device also has the advantages of simple structure, convenient operation and reusability. Its structural design is reasonable, and the installation and disassembly process is simple and quick, without the need for complicated tools and equipment, which reduces construction costs. At the same time, the protective plate can be reused, reducing resource waste and meeting the environmental protection requirements of modern building construction. Attached Figure Description
