Description
Technical Field
[0001] This utility model relates to a protective structure for elevator shafts in building construction, belonging to the field of building construction technology. Background Technology
[0002] Construction elevator shafts are vertical spatial structures that provide the operating path for construction elevators (also known as construction hoists) during building construction. They typically span multiple floors of a building and serve as the track space for the elevator's vertical movement. As a vertical space traversing multiple floors, without proper protection, construction workers may slip, fall, or accidentally enter the shaft, resulting in falls from heights (one of the high-risk accident types in construction). Protective structures (such as safety doors at floor entrances and safety nets inside the shaft) physically isolate hazardous areas.
[0003] During construction, protective doors are installed on each floor, protective nets or barriers are installed on the sides, and protective canopies are added to the top. After completion, recyclable components are removed. These protective measures are designed to prevent people from falling or being struck by objects, ensure elevator operation, isolate dangerous areas, and comply with safety regulations. However, traditional protective measures have limitations such as being easily opened without authorization and insufficient impact resistance, and need to be implemented in conjunction with management to be effective.
[0004] In existing technologies, the installation of some elevator shaft protection structures in building construction requires the use of bolt-tightening tools to disassemble and assemble the protective netting. Each operation requires tightening the bolts one by one, which is not only time-consuming and labor-intensive, but also significantly slows down the construction progress and reduces construction efficiency in multi-story building construction by repeating this process floor by floor. Therefore, a new elevator shaft protection structure for building construction is proposed to solve the above problems. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a protective structure for elevator shafts in building construction to solve the existing problems.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a protective structure for elevator shafts in building construction, including a protective net, a shaft is provided on the rear side of the protective net, two main blocks are slidably connected inside the left and right sides of the shaft, the rear side of the protective net is fixedly connected to the front side of the main blocks, and sliding components are slidably connected inside the left and right ends of the two main blocks, the sliding components include a blocking block, and the blocking block 5 is triangular. Each sliding component includes a stop block. The two stop blocks are slidably connected to the interior of the left and right ends of the main body block, respectively. A bearing block is fixedly connected to the side of the two stop blocks that is close to each other. The two bearing blocks are slidably connected to the interior of the main body block.
[0007] Preferably, the front and rear ends of the two sliding components are fixedly connected to rotating shafts, the front and rear ends of the bearing blocks are rotatably connected to the outside of the two rotating shafts, and the outside of the multiple bearing blocks are slidably connected to the inside of the left and right ends of the shaft.
[0008] Preferably, multiple rotating shafts are internally rotatably connected to transmission blocks, two transmission blocks are rotatably connected to a rotating block at their adjacent ends, and the two rotating blocks are externally slidably connected to the interior of the main body block.
[0009] Preferably, the two rotating blocks are internally slidably connected by a sliding column, the sliding column is externally fixedly connected to the inside of the main block, and a spring is sleeved on the outside of the sliding column 11. The front and rear ends of the spring are fixed to the adjacent side of the two rotating blocks, and the two ends of the spring are welded to the adjacent side of the two rotating blocks.
[0010] Preferably, the front end of the shaft has recessed grooves on both the left and right sides for the installation of the main block.
[0011] Preferably, the protective net has multiple guide posts slidably connected inside, a barrier net is fixedly connected to the front side of the multiple guide posts, a spring is sleeved on the outside of each of the multiple guide posts, the rear side of the protective net is fixedly connected to the front side of the multiple springs, and a limiting block is fixedly connected to the rear side of each of the multiple guide posts.
[0012] The beneficial effects of the utility model are: This utility model has a simple structure and is easy to operate. It is equipped with two electric telescopic rods that extend and push the moving plate to descend, which in turn drives the lifting plate to descend, causing the push plate to move. This in turn drives the connecting plate and scraper to move. One end of the scraper contacts the outer wall of the roller. When the roller rolls, the impurities on its surface can be scraped off by the scraper, thus facilitating the normal movement of the transfer trolley.
[0013] It is also equipped with a rocker arm to drive the threaded rod to rotate, so that the two sliders move closer to each other. When the rocker arm moves closer to each other, the two extrusion plates move up, pushing the adjustment plate upward. At this time, the roller leaves the through-hole and contacts the bottom of the steel structure. At this time, the staff pulls the steel structure, and the steel structure moves along the top of the roller. The roller rotates, the friction is reduced, and the unloading is convenient.

Detailed Implementation
[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0016] Reference Figures 1 to 3 This utility model provides an embodiment of a protective structure for an elevator shaft in building construction, including a protective net 1, which is installed at the gap to provide protection. A shaft 3 is located behind the protective net 1, allowing the elevator to move stably through the restriction and guidance of the shaft 3. Two main blocks 4 are slidably connected to the left and right sides of the shaft 3, allowing the main blocks 4 to slide stably. The rear of the protective net 1 is fixedly connected to the front of the main blocks 4, providing a mounting surface for the main blocks 4 to fix the protective net 1. Sliding components are slidably connected to the left and right ends of the two main blocks 4, each including a triangular blocking block 5. Multiple sliding components each include a blocking block 5, with the outer surfaces of two blocking blocks 5 slidably connected to the interior of the left and right ends of the main blocks 4, so that when the main blocks 4 are pushed to slide, the blocking blocks 5 slide synchronously. A bearing block 6 is fixedly connected to the adjacent side of each of the two blocking blocks 5. The two blocking blocks 5 slide on the shaft 3 with inclined surfaces, causing the blocking blocks 5 to press against the bearing block 6 on the adjacent side, thus pushing the bearing block 6 to move. Two bearing blocks 6 are externally slidably connected to the inside of the main body block 4. They slide under pressure from the inclined surface of the blocking block 5, thus driving the bearing blocks 6 to slide. Rotating shafts 7 are fixedly connected to the front and rear ends of both sliding components. The blocking blocks 5 drive the bearing blocks 6 to slide, thereby causing the rotating shafts 7 to move synchronously. The front and rear ends of the bearing blocks 6 are rotatably connected to the outside of the two rotating shafts 7, respectively. When the bearing blocks 6 slide, they can drive the rotating shafts 7 to slide synchronously. Multiple bearing blocks 6 are externally slidably connected to the inside of the left and right ends of the shaft 3. The main body block 4 slides, causing the bearing blocks 6 to slide synchronously inside the left and right ends of the shaft 3, thus allowing them to slide stably inside the shaft 3. The outside of the rotating shafts 7 is fixed to the inside of both ends of the bearing blocks 6. When the bearing blocks 6 drive the rotating shafts 7 to slide, they restrict the rotating shafts 7 from sliding out. Multiple rotating shafts 7 are internally connected to transmission blocks 8. These shafts move synchronously via a bearing block 6, which in turn drives two transmission blocks 8 to rotate. A rotating block 9 is rotatably connected to the adjacent ends of the two transmission blocks 8. Movement of the rotating shafts 7 causes the two transmission blocks 8 to rotate, which in turn pushes the two rotating blocks 9 to slide. The two rotating blocks 9 are externally slidably connected to the interior of the main body block 4. The rotation of the transmission blocks 8 drives the rotating blocks 9 to slide within the main body block 4. A sliding column 11 is internally slidably connected to the two rotating blocks 9, providing stable guidance. The sliding column 11 is externally fixedly connected to the interior of the main body block 4, with both ends welded to the interior of the main body block 4 to restrict the internal space. A spring 10 is sleeved on the exterior of the sliding column 11, and by restricting the spring 10, the force on the spring 10 is evenly distributed. The front and rear ends of spring 10 are fixed to the adjacent sides of the two rotating blocks 9. The two rotating blocks 9 slide towards each other, compressing spring 10, which stores elastic potential energy, and then applies a force in the opposite direction to the rotating blocks 9 to reset them. The distal ends of spring 10 are fixedly connected to the adjacent sides of the two rotating blocks 9, and both ends of spring 10 are welded to the adjacent sides of the two rotating blocks, thus moving the rotating blocks 9. Each of the two main blocks 4 has a placement cavity 12 inside for installing components inside the main block 4. The front left and right sides of the wellhead 3 each have an embedded groove 13 for installing the main block 4. Reference Figure 4 and Figure 5 The protective net 1 has multiple guide posts 14 internally slidably connected, providing support as the guide posts 14 slide. A barrier net 2 is fixedly connected to the front of each guide post 14; when the barrier net 2 is impacted, it causes the guide posts 14 to slide synchronously, providing stable guidance. Each guide post 14 is fitted with a second spring 15, ensuring even force distribution through the guide posts 14. The rear of the protective net 1 is fixedly connected to the front of the second spring 15, with one end of each spring 15 welded to the rear of the net 1 to stabilize its tension. Each guide post 14 has a limiting block 16 fixedly connected to its rear, secured by welding, allowing the guide posts 14 to slide along the limiting block 16. The rear of each spring 15 is fixedly connected to the front of the limiting block 16, with one end welded to the front of the limiting block 16 to provide support for its reset.
[0017] Working principle: By pushing the main block 4 into the well 3, the blocking block 5 slides synchronously, and then squeezes towards the side close to the blocking block 5, thereby pushing the bearing block 6. The synchronous movement of the bearing block 6 drives the rotating shaft 7, which in turn drives the transmission block 8 to rotate. The rotation of the transmission block 8 drives the rotating block 9 to slide, thereby stretching the spring 10, storing the spring potential energy. When the spring potential energy is released, it pulls the rotating block 9 to rotate, so that the blocking block 5 is reset and locked inside the well 3 for installation. Upon impact, the barrier net 2 synchronously pushes the guide post 14, causing the limiting block 16 to move synchronously. Through the sliding of the limiting block 16, the second spring 15 is stretched, generating spring potential energy. When the spring potential energy is released, the second spring 15 pulls the limiting block 16, thereby pushing the guide post 14 to reset, absorbing the impact force and reducing the pain caused to construction workers when they are hit.
