[0001] The utility model belongs to the technical field of construction hole protection, and in particular relates to a foldable hoistway construction elevator protection door. Background Art

[0002] With the development of high-rise buildings, construction elevators are an indispensable vertical transportation equipment during the main construction phase and the decoration and renovation construction phase.

[0003] In order to reduce the accident rate of vertical transportation machinery and equipment, improve vertical transportation efficiency, and shorten the overall construction period of the building facade, shaft construction elevators are now mostly used as vertical transportation machinery and equipment. Therefore, the reasonable installation of shaft elevator protective door devices during the construction process is a very necessary work arrangement.

[0004] Traditional hoistway elevator opening protection mostly uses steel pipes, square wood or standardized protective baffles, which need to be fixed to the outside of the opening by expansion bolts or settings. This temporary protective device cannot be opened, which is inconvenient for the entry and exit of personnel and materials using the hoistway elevator. Moreover, if a whole piece of standardized protection is used as a temporary opening door leaf, it will greatly affect the use space of the elevator hall. The protective door needs to be dismantled and modified during construction, which is labor-intensive, time-consuming and inconvenient to operate. In addition, traditional standardized protective devices are larger than the vertical size of the elevator hoistway opening and need to be installed on the wall outside the opening, which affects the construction of later wall tiling and other decorative decorations. Utility Model Content

[0005] The utility model aims to solve the problem that the traditional hoistway elevator opening protection is mostly fixed and cannot be opened, which is inconvenient for personnel and materials using the hoistway elevator to enter and exit.

[0006] The utility model provides the following technical scheme: a foldable elevator protective door for shaft construction, comprising a plurality of protective door leaves connected by rotating hinges, the opening and closing directions of adjacent protective door leaves are opposite, the width of each protective door leaf is equal to the width of the elevator opening / the total number of protective door leaves, the protective door leaves located on both sides are connected to the elevator opening, the protective door leaves on one side are connected to the elevator opening shear wall by rotating hinges through self-tapping screws, and the protective door leaves on the other side are connected to the elevator opening shear wall through lock buckles, the lock buckles are installed on the inner side of the elevator opening, the lock buckles include wall components and door leaf components, the door leaf components are installed on the protective door leaves, and the wall components are installed on the elevator opening shear wall.

[0007] Furthermore, the door leaf component includes a seat body and a 90° rotating buckle, the seat body is fixed on the protective door leaf, the first right-angled side of the 90° rotating buckle is hinged to the seat body, and the curved surface formed by the 90° rotating buckle rotating around the hinge axis is a cylindrical surface perpendicular to the protective door leaf. A slot that passes through the front and back and has an entrance facing upward is provided on the wall component, and the second right-angled side enters and exits the slot when the 90° rotating buckle rotates around the hinge axis.

[0008] Furthermore, the 90° rotating buckle is connected to the pin on the seat body through the through slot on the first right angle side parallel to the length direction.

[0009] Furthermore, a limiting cap is installed at the end of the second right-angled side of the 90° rotating buckle. The limiting cap is perpendicular to the second right-angled side and parallel to the first right-angled side. After the second right-angled side enters the slot, the limiting cap stops at the edge of the slot.

[0010] Furthermore, two protective door leaves form an elevator protective door.

[0011] Furthermore, the protective door leaf comprises an external keel welded with square steel, a foot plate welded at the bottom of the inner circle of the external keel, a baffle welded in the middle, a protective mesh welded outside the foot plate and the baffle, and the door leaf component is installed at the baffle.

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] The utility model provides a foldable elevator protection door for shaft construction, which solves the problems that the existing hole protection needs to be dismantled and modified when the elevator is used, which is labor-consuming and time-consuming, inconvenient to operate, occupies space, and affects subsequent construction.

[0014] The protective door is made of lightweight steel, and its own connection method can be welded, which is easy to process, light in weight, strong in strength, stable in structure, not easy to damage, durable and high in utilization rate.

[0015] The protective door is fully enclosed to prevent workers from climbing; the lock is set on the inside of the protective door and cannot be opened from the outside. The other part of the lock is fixed to the side of the shear wall to prevent the protective door leaf from shifting into the shaft, increasing safety during use. In addition, the 90° rotating buckle can be used as an opening and closing handle for the protective door leaf, which is convenient for internal opening.

[0016] The protective door is connected to the main structure by hinges and self-tapping screws, which are both secure and flexible to open. This connection method is easy to install and remove and can be used multiple times.

[0017] The protective door adopts double-door folding type. When opened, it can reduce the occupancy of the limited space in the elevator hall and increase the space utilization rate of the elevator hall.

[0018] Since this protective door is installed on the inner side of the elevator shaft opening and is lower than the shear wall plane, it does not affect the subsequent series of decoration and renovation processes such as tiling of the elevator hall wall. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0026] like Figure 1 , Figure 2 As shown: a foldable elevator protective door for shaft construction, comprising a plurality of protective door leaves 1 connected by rotating hinges 2, the opening and closing directions of adjacent protective door leaves 1 are opposite, the width of each protective door leaf 1 is equal to the width of the elevator opening / the total number of protective door leaves 1, the protective door leaves 1 on both sides are connected to the elevator opening, one of the protective door leaves 1 is connected to the shear wall of the elevator opening by a rotating hinge 2 through self-tapping screws, and the other side of the protective door leaf 1 is connected to the shear wall of the elevator opening through a lock, the lock is installed on the inner side of the elevator opening, the lock comprises a wall component 4 and a door leaf component 3, the door leaf component 3 is installed on the protective door leaf 1, and the wall component 4 is installed on the shear wall of the elevator opening.

[0027] Specifically, two protective door leaves 1 form an elevator protective door, and the two protective door leaves 1 open outward from the elevator opening. When the protective door is subjected to external thrust, it closes more tightly to prevent falling objects or people from accidentally falling.

[0028] like Figure 3 , Figure 4 As shown: the door leaf component 3 includes a seat body 3.1 and a 90° rotating buckle 3.2. The seat body 3.1 is fixed on the protective door leaf 1. The first right-angled side of the 90° rotating buckle 3.2 is hinged to the seat body 3.1. The curved surface formed by the rotation of the 90° rotating buckle 3.2 around the hinge axis is a cylindrical surface perpendicular to the protective door leaf 1. The wall component 4 is provided with a card slot 4.1 that runs through the front and back and has an upward entrance. When the 90° rotating buckle 3.2 rotates around the hinge axis, the second right-angled side enters and exits the card slot 4.1. When the protective door is opened, a lateral pulling force is applied to the wall component 4, and an upward thrust is required to unlock the 90° rotating buckle 3.2. The two forces are perpendicular, so the lock will not be accidentally opened if it is not actively controlled by non-operating personnel. The 90° rotating buckle 3.2 serves as the opening and closing handle and internal locking device of the protective door.

[0029] The 90° rotating buckle 3.2 is connected to the pin 3.4 on the seat body 3.1 through the through slot 3.3 on the first right angle side parallel to the length direction, so that the use range of the 90° rotating buckle 3.2 can be adjusted.

[0030] A limiting cap 3.5 is installed at the end of the second right-angled side of the 90° rotating buckle 3.2. The limiting cap 3.5 is perpendicular to the second right-angled side and parallel to the first right-angled side. After the second right-angled side enters the slot 4.1, the limiting cap 3.5 stops at the edge of the slot 4.1. The limiting cap 3.5 further prevents the 90° rotating buckle 3.2 from sliding off the wall component 4 when the protective door is subjected to external tension.

[0031] like Figure 5 As shown: the protective door leaf 1 includes an external keel 1.1 welded with square steel, the external keel 1.1 adopts 5 cm lightweight square steel, the bottom of the inner circle of the external keel 1.1 is welded with a foot plate 1.2, the middle is welded with a baffle 1.3, the foot plate 1.2 and the baffle 1.3 are welded with a protective mesh 1.4, the baffle 1.3 and the foot plate 1.2 are made of hard iron sheet, and the door leaf component 3 is installed at the baffle 1.3 to prevent it from being opened from the outside of the elevator opening.

[0032] The use of this elevator protective door saves both effort and trouble. It reduces the safety risks faced by workers in the elevator shaft during operation. At the same time, it is fully suitable for the use of elevator protective doors in shaft construction, and has been well received by workers during the main construction stage and the decoration stage.
