Description

Technical Field

[0001] This utility model relates to the field of tunnel safety protection technology, specifically a tunnel safety protection locking device. Background Technology

[0002] A floor slab generally refers to a precast concrete component manufactured in a prefabrication yard. It is the load-bearing part of a floor layer, vertically dividing a building into several floors and transferring the vertical loads of people and furniture, as well as the floor slab's own weight, to the foundation through walls, beams, or columns. Based on the materials used, floor slabs can be classified into several types, including wooden floor slabs, brick arch floor slabs, reinforced concrete floor slabs, and steel-lined load-bearing floor slabs. An existing patent, patent publication number CN211949697U, discloses a protective cover device for a pre-reserved material loading opening to prevent movement. The device includes a cover plate for covering a pre-reserved material loading opening. A limiting mechanism that extends into the opening is located below the cover plate. A vertically extending and rotatable central axis is located in the middle of the cover plate. A handle is located at the upper end of the central axis above the cover plate, and a locking rod is located at the lower end below the limiting mechanism. The locking rod is spaced apart from the side wall of the pre-reserved material loading opening when the central axis is at a first angle, and abuts against the side wall when the central axis is at a second angle. The pre-reserved material loading opening anti-movement protective cover plate device provided in this application has the characteristics of preventing horizontal and vertical movement, preventing personnel from arbitrarily opening the cover plate, and improving construction safety.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: in practical applications, it is inconvenient to disassemble and install protective devices, which will affect the ease of use of the device and reduce its efficiency, causing inconvenience in subsequent use. Therefore, we propose a safety protection locking device for openings to solve the above-mentioned problems. Utility Model Content

[0013] Beneficial effects

[0014] This utility model provides a safety protection locking device for openings. Compared with the prior art, it has the following advantages:

[0015] This safety locking device for openings works by placing a positioning plate under the floor slab, then passing an iron chain through the opening via a plug rod, inserting a screw into a limiting plate on the horizontal plate, and finally tightening a nut.
