It includes the entire production process from construction preparation, groundbreaking to project completion acceptance.
[0003] At present, in construction, as the height of buildings continues to increase, construction elevators have become a construction machine that must be used in every construction project. Many safety accidents on construction sites are caused by improper protection around construction elevators. The construction of construction elevator protective doors can effectively prevent people from being hit, falling, and objects falling from high-rise buildings, reducing the occurrence of safety accidents. Therefore, more attention needs to be paid to the safety of construction elevator protective doors. Nowadays, construction elevator protective doors have become one of the necessary protective equipment on high-rise building construction sites. Please refer to Figure 1 As shown, the existing construction elevator protective door usually includes a left protective door 1 and a right protective door 2, which are both arranged vertically and along the left and right directions and adjacent to each other on the left and right sides. A latch 3 is installed on the right protective door 2, which is arranged along the left and right directions and can be moved left and right and can be rotated around the left and right directions. A socket 4 is arranged on the left protective door 1 along the left and right directions, and the socket 4 is located on the left side of the latch 3. The socket 4 is inserted by moving the latch 3 to the left. A lock nose 5 is also installed on the right protective door 2, and the lock nose 5 is arranged vertically and along the front-back direction and is located below the latch 3.

[0030] See also Figure 2 As shown, in a specific embodiment of the utility model, the construction elevator protective door switch anti-dropping device of the utility model includes a fixing plate 7, a housing 8, a clamping pin 9, a pull ring 10, an elastic member 11 and a fixing member 12, wherein:
[0031] The fixing plate 7 and the shell 8 are both arranged vertically and along the left-right direction. The shell 8 is located in front of the middle part of the fixing plate 7 and connected to the middle part of the fixing plate 7. The card pin 9 is arranged along the left-right direction and can be movably penetrated through the left and right sides of the shell 8 along the left-right direction. The left end of the card pin 9 is exposed on the left side of the shell 8 and protrudes to the left of the fixing plate 7. The right end of the card pin 9 is exposed on the right side of the shell 8 and is provided with the pull ring 10. The elastic member 11 is arranged along the left-right direction and located in the shell 8. The left and right ends of the elastic member 11 are respectively connected to the card pin 9 and the shell 8.
[0032] The fixing member 12 is arranged along the front-to-back direction and is located outside the outer shell 8. The fixing member 12 passes through the fixing plate 7 along the front-to-back direction and is used to pass through the right protective door 2 of the construction elevator protective door along the front-to-back direction to fix the fixing plate 7 and the right protective door 2 together.
[0033] The fixing plate 7 may have any suitable shape, see Figure 2 As shown, in a specific embodiment of the present invention, the fixing plate 7 is a rectangular plate.
[0034] The housing 8 can be made of any suitable material. In a specific embodiment of the present invention, the housing 8 is a metal housing.

[0036] The pull ring 10 may have any suitable shape, see Figure 2 As shown, in a specific embodiment of the present invention, the pull ring 10 is a circular pull ring.
[0037] The pull ring 10 can be arranged in any suitable direction. Figure 2 As shown, in a specific embodiment of the present utility model, the pull ring 10 is arranged vertically and along the left-right direction.
[0038] The elastic member 11 may be any suitable elastic member, see Figure 2 As shown, in a specific embodiment of the present utility model, the elastic member 11 is a telescopic spring, and the telescopic spring is sleeved on the clamping pin 9 .
[0039] The fixing member 12 can be any suitable fixing member. In a specific embodiment of the present invention, the fixing member 12 is a fixing screw.
[0040] The number of the fixing members 12 can be determined as needed. Preferably, the number of the fixing members 12 is multiple, and the multiple fixing members 12 are arranged around the housing 8 at intervals.
