Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1-4 As shown, an adjustable construction elevator floor door includes a fixed column 1 and a lifting column 2. The lifting column 2 is slidably inserted into a connecting slot on the fixed column 1, and is fixedly connected to the fixed column 1 by a positioning pin assembly 3. A grounding frame 4 is installed on the fixed column 1, and a lifting frame 5 is slidably inserted into the grounding frame 4. The grounding frame 4 and the lifting frame 5 are fixedly connected to the fixed column 1 and the lifting column 2 respectively by a limiting connector 6. A mesh 7 is fixedly installed on the inner wall of both the grounding frame 4 and the lifting frame 5. In use, the position of the lifting column 2 on the fixed column 1 is adjusted according to the required floor height by sliding the lifting column 2 to the appropriate height. After reaching the specified height, the lifting column 2 is securely connected to the fixed column 1 using the positioning pin assembly 3, ensuring that the lifting column 2 will not slide arbitrarily and guaranteeing safety and stability. Next, the lifting frame 5 is slid on the grounding frame 4 to the position corresponding to the lifting column 2, and fixed to the lifting column 2 and the fixed column 1 respectively through the limiting connector 6. This forms a complete floor door frame. At this time, the mesh 7 inside the grounding frame 4 and the lifting frame 5 plays a protective role, preventing people from falling accidentally and maintaining the transparency of the construction area. The entire adjustment process is simple and quick, and can be flexibly adjusted according to the actual needs of different floors, greatly improving the safety and practicality of the construction elevator floor door.
[0021] A connecting strip 8 is fixedly installed on the top of the lifting frame 5. The connecting strip 8 is fixedly connected to the top of the lifting frame 5 by fixing bolts 9. This not only enhances the stability of the structure, but also facilitates the connection with adjacent components. The connecting strip 8 is tightly connected to the top of the lifting frame 5 by fixing bolts 9, ensuring stability under various usage conditions and providing additional safety for the construction elevator floor door.
[0022] The positioning pin assembly 3 includes a U-shaped mounting base 301, which is fixed to the side wall of the fixed column 1. A positioning pin 302 is slidably mounted on the U-shaped mounting base 301. One end of the positioning pin 302 is inserted into a positioning pin hole that is linearly opened on the lifting column 2. A lifting head 303 is fixedly mounted on the other end of the positioning pin 302. An annular connecting block 304 is fixedly sleeved on the positioning pin 302. The annular connecting block 304 is elastically connected to the U-shaped mounting base 301 through a clamping spring 305. When in use, the positioning pin 302 is pulled outward by holding the lifting head 303. At this time, the clamping spring 305 is compressed by force, and the positioning pin 302 disengages from the positioning pin hole of the lifting column 2. Next, adjust the height of the lifting column 2 as needed. After adjustment, release the lifting head 303, press the spring 305 to release the elastic force, and push the positioning pin 302 to slide along the U-shaped mounting base 301 until its other end is precisely inserted into the corresponding positioning pin hole on the lifting column 2 to achieve a firm fixed connection. The whole operation process is simple and quick, ensuring that the height adjustment of the construction elevator floor door is stable and reliable.
[0023] The limiting connector 6 includes a first ear plate 601 and a second ear plate 602. The first ear plate 601 and the second ear plate 602 are fixed on the inner walls of the fixed column 1 and the lifting column 2, and the first ear plate 601 and the second ear plate 602 are horizontally aligned. The grounding frame 4 and the lifting frame 5 are located between the first ear plate 601 and the second ear plate 602. The first ear plate 601 and the second ear plate 602 are fixedly connected by a connecting bolt 603, and the connecting bolt 603 is inserted into the mesh 7. In use, the grounding frame 4 and the lifting frame 5 are placed between the first ear plate 601 and the second ear plate 602 of the fixed column 1 and the lifting column 2, respectively, to ensure that each component is horizontally aligned. Then, the connecting bolt 603 passes through the mesh 7 to tightly fix the first ear plate 601 and the second ear plate 602 together. In this way, not only is the stability of the floor door structure strengthened, but also the reliable connection between the grounding frame 4 and the lifting frame 5 and the column is ensured. At the same time, the design of the mesh 7 also enhances the safety protection effect.
