Description

Technical Field

[0001] The utility model relates to a safety protection device for a construction elevator door opening. Background Art

[0002] In the field of construction technology, construction elevators are used as a vertical transportation tool in engineering construction due to their stable performance, high structural safety, and economical use. During the construction process, a doorway is opened on the side of each floor of the building close to the construction elevator for construction workers to enter and exit the floor. Generally, construction elevators are used in conjunction with protective doors, which are set on the doorway to replace the scaffolding outside the building wall, making it convenient for construction workers to enter and exit the building, while also protecting the construction workers inside the building.

[0003] At present, due to the different sizes of elevator door openings in existing buildings, it is necessary to customize protective doors that meet the sizes of the elevator door openings, which reduces the applicability of the equipment to a certain extent and is more costly in terms of materials.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0020] The embodiment of the utility model comprises a mounting structure 1, a protective structure 2 and a door bolt 3.

[0021] The mounting structure 1 is used to support the equipment, and includes a mounting frame 11 , a bidirectional screw rod 12 , a movable abutment plate 13 , a handle 16 and a rubber gasket 17 .

[0022] The bidirectional screw rod 12 is arranged horizontally and is rotatably installed in the middle position inside the mounting frame 11 through a bearing. One end of the bidirectional screw rod 12 passes through and extends out of the mounting frame 11, and a hexagonal handle 16 is provided on the end. A movable clamping plate 13 is respectively installed on the right-handed thread and the left-handed thread of the bidirectional screw rod 12 through a screw nut, and the movable clamping plate 13 is set to be L-shaped. The movable clamping plate 13 is slidably installed in the mounting frame 11, specifically, a movable groove 15 is provided on the mounting frame 11, and the movable clamping plate 13 is slidably installed in the movable groove 15. A rubber gasket 17 is pressed and fixed on the movable clamping plate 13, and fixing holes 18 are provided on the movable clamping plate 13 and the rubber gasket 17. An insertion groove 14 is provided on the movable clamping plate 13, and the position of the movable groove 15 corresponds to the position of the insertion groove 14. When in use, when the bidirectional screw rod 12 is rotated by the handle 16, the movable clamping plate 13 sleeved on the right-handed and left-handed threads of the bidirectional screw rod 12 can be synchronously moved outward or inward, thereby the L-shaped inner wall surface of the movable clamping plate 13 can be pressed against the wall surface inside the door opening, and the toughness and elasticity of the rubber gasket 17 can enhance the friction between it and the wall surface inside the door opening, and the expansion bolt is connected to the wall through the fixing hole 18, so as to fix the position of the mounting structure 1. The mounting structure 1 is divided into two groups, and the two groups of mounting structures 1 are arranged up and down, and are respectively installed at the upper and lower ends inside the door opening.

[0023] The protective structure 2 is used to protect construction workers, and the protective structure 2 includes a connecting rod 21 , a rotating plate 22 , a door plate 23 and a tightening bolt 24 .

[0024] The connecting rod 21 passes through the moving groove 15 and is inserted into the inside of the insertion groove 14, so that the connecting rod 21 is fixed to the moving abutting plate 13. One end of the rotating plate 22 is rotatably sleeved on the connecting rod 21. The door panel 23 is slidably sleeved on the rotating plate 22 left and right, and the outer diameter of the connecting rod 21 matches the inner diameter of the insertion groove 14 and the width inside the moving groove 15. The threads on the upper and lower ends of the inner surface of the door panel 23 are connected with a tightening bolt 24, and the door panel 23 and the rotating plate 22 are fixed by the tightening bolt 24. When in use, when the moving abutting plate 13 moves, the connecting rod 21 can be synchronously driven to move, and the rotating plate 22 can be moved left and right on the door panel 23, so that the equipment can be adjusted according to the actual width of the door opening; and when the rotating plate 22 is hinged and rotated on the connecting rod 21, it can synchronously drive the door panel 23 to rotate, so that the door panel 23 is opened or closed. The protective structure 2 is divided into two groups, which are arranged on the left and right.

[0025] The door bolt 3 is installed on the door panel 23 and is used to lock the door panel 23 .

[0026] Working principle: The utility model is placed at the elevator door opening under construction, and the hexagonal handles 16 of the two sets of mounting structures 1 are rotated by external instruments to rotate the two sets of bidirectional screws 12, so that the movable clamping plate 13 mounted on the bidirectional screws 12 is synchronously moved outward, so that the rubber gasket 17 on the movable clamping plate 13 is pressed against the wall surface inside the door opening, and then the expansion bolt is passed through the fixing hole 18 opened inside the surface of the movable clamping plate 13 and the rubber gasket 17, so that the expansion bolt is connected to the wall, thereby completing the fixing of the utility model on the elevator door opening. While the movable clamping plate 13 moves, the connecting rod 21 inserted in the insertion groove 14 moves synchronously in the inside of the movable groove 15 with the movement of the movable clamping plate 13, driving the rotating plate 22 to move inside the door plate 23. When it moves to a suitable position, the clamping bolt 24 is rotated so that one end of the clamping bolt 24 is pressed against the outer surface of the rotating plate 22, fixing the position of the rotating plate 22. When the bolt 3 is opened, the two sets of door panels 23 can be unfolded by rotating the rotating plate 22, and the staff can enter the interior of the building. On the contrary, when the bolt 3 is closed, the door panels 23 can be locked.

[0027] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is only an example of the structure of the utility model. All equivalent changes or simple changes made based on the structure, features and principles described in the patent concept of the utility model are included in the protection scope of the utility model patent.
