Description

Technical Field

[0001] This utility model specifically relates to a protective device for reserved holes in building construction, belonging to the field of hole protection technology. Background Technology

[0002] In building construction, pre-reserved holes at the same location on multiple floors serve the core purpose of improving construction efficiency and adapting functions in the vertical direction: they can create convenient vertical channels to support the top-down layered transportation of flexible pipelines (cables, hoses), facilitate the vertical transfer of small construction tools and materials, reduce the trouble of detours when moving across floors, and some holes also serve as ventilation channels to help air circulation in the construction area. The protection of pre-reserved holes is equally important, as it can effectively prevent construction workers from falling and materials from falling and causing safety accidents, while preventing dust and debris from entering the holes and ensuring that subsequent use is not affected.

[0003] However, most current protection methods simply seal the openings, ignoring the special need for openings in the same location on multiple floors of a building. This sealing method hinders the transportation of wiring tools. Openings in the same location on multiple floors are convenient channels for temporarily transporting flexible pipelines and small construction tools. Directly sealing them requires detours, prolonging transportation time and reducing construction efficiency.

[0004] To address the aforementioned issues, this application proposes a protective device for pre-reserved holes in building construction. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a protective device for pre-reserved holes in building construction. This device consists of a connecting pipe, a bottom cover, and a liftable top cover. The bottom cover is placed over the lower hole. Synchronous transmission via a gear ring drives four sets of threaded rods to rotate synchronously. Through threaded engagement with the threaded holes, the top cover rises, pressing against the upper wall and covering the outside of the upper hole, thus achieving simultaneous protection for the holes on both the upper and lower sides. After installation, the upper and lower holes remain connected through the connecting pipe, facilitating the vertical transport of flexible pipelines and other components, as well as meeting the vertical transfer requirements of small construction tools and materials, thereby solving the problems mentioned in the background section.

[0006] A protective device for pre-reserved holes in building construction, comprising:

[0007] A vertically arranged connecting pipe has a bottom cover fixedly installed at its lower end and a top cover slidably fitted at its upper end. A set of lifting rods are installed around the bottom of the top cover. The lifting rods have threaded holes, and threaded rods are threadedly connected to the threaded holes. A hollow ring is fixedly installed on the outside of the connecting pipe, and a gear ring is rotatably installed inside the hollow ring. Multiple sets of gears are meshed on the outside of the gear ring.

[0008] The connecting pipe has an opening on one side below it and an air inlet pipe on the other side below it. An air collection hood is installed at one end of the air inlet pipe and an air intake fan is installed inside the air collection hood.

[0009] In a preferred embodiment, both the top cover and the bottom cover are conical structures and are arranged in a mirror image.

[0010] In a preferred embodiment, the top cover, bottom cover, and connecting pipe are all made of stainless steel.

[0011] In a preferred embodiment, a set of rubber anti-slip rings are respectively installed on the upper surface of the top cover and the lower surface of the bottom cover.

[0012] In a preferred embodiment, the multiple sets of gears correspond to the positions and quantities of multiple sets of threaded rods. A transmission rod is installed inside the gear. The upper end of the transmission rod passes through the hollow ring and is fixedly connected to the threaded rod. The transmission rod and the hollow ring form a rotatable connection. The gear ring is located outside the connecting pipe. An oil injection hole is opened on one side above the hollow ring.

[0013] In a preferred embodiment, a set of drive motors is installed on one side below the hollow ring, and the output shaft of the drive motors is connected to one of the transmission rods that are connected to gears.

[0014] In a preferred embodiment, a cap is threadedly connected to one side of the dispensing / removing port, and the dispensing / removing port is connected to the inside of the connecting pipe.

[0015] In a preferred embodiment, the air inlet pipe is internally connected to the connecting pipe, and a filter plate is installed on the front side of the air collection hood, with multiple sets of filter holes on the surface of the filter plate.

[0016] Beneficial effects:

[0017] 1. By designing a connecting pipe, a bottom cover, and a liftable top cover, the bottom cover is placed over the lower hole. With the synchronous transmission of the gear ring, four sets of threaded rods are driven to rotate synchronously. Through the threaded engagement with the threaded hole, the top cover is driven to rise, abut against the upper wall, and cover the outside of the upper hole, achieving synchronous protection of the holes on both the upper and lower sides. After installation, the upper and lower holes are kept connected by the connecting pipe, which facilitates the vertical transportation of flexible pipelines and meets the vertical transfer needs of small construction tools and materials. During the transfer process, items can be easily retrieved and placed through the pick-and-place port.

[0018] 2. By designing an air intake fan, a gas collection hood, and a filter plate, after the device is installed, the air intake fan can draw air from inside the building. The air is filtered by the filter plate and then enters the gas collection hood, then is transmitted to the connecting pipe, and finally discharged through the reserved holes. This not only protects the holes, but also effectively removes dust raised inside the building and smoke generated during construction, avoids the accumulation of smoke and dust, and optimizes the air quality of the construction environment.

[0025] 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.

[0026] Please see Figures 1-5 As shown, a protective device for pre-reserved holes in building construction includes:

[0027] A vertically arranged connecting pipe 1 has a bottom cover 3 fixedly installed at its lower end and a top cover 2 slidably fitted at its upper end. A set of lifting rods 4 are installed around the bottom of the top cover 2. The lifting rods 4 have threaded holes, and threaded rods 5 are threadedly connected to the threaded holes. A hollow ring 6 is fixedly installed on the outside of the connecting pipe 1. A gear ring 13 is rotatably installed inside the hollow ring 6. Multiple sets of gears 12 are meshed on the outside of the gear ring 13.

[0028] A pick-up and drop-out port 8 is provided on one side below the connecting pipe 1, and an air inlet pipe 10 is installed on the other side below it. An air collection hood 11 is installed at one end of the air inlet pipe 10, and an air intake fan 14 is installed inside the air collection hood 11.

[0029] Please see Figures 1-2As shown, both the top cover 2 and the bottom cover 3 are conical structures and are mirror images of each other. The conical structure can increase the contact area with the edge of the hole and improve the sealing of the protective cover. The mirror image setting can be adapted to the installation direction of the upper and lower holes respectively.

[0030] The top cover 2, bottom cover 3, and connecting pipe 1 are all made of stainless steel. Stainless steel has high strength and corrosion resistance, can withstand collisions and dust erosion in the construction environment, extend the service life of the device, and meet the structural stability requirements during construction.

[0031] Please see Figures 1-2 As shown, a set of rubber anti-slip rings are installed on the upper surface of the top cover 2 and the lower surface of the bottom cover 3. The rubber anti-slip rings can increase the friction between the top cover 2, the bottom cover 3 and the wall, prevent the device from shifting due to vibration or external force after installation, and fill the gaps in the contact surface to improve the protective sealing.

[0032] Please see Figures 1-4 As shown, multiple sets of gears 12 correspond to multiple sets of threaded rods 5 in position and quantity. A transmission rod is installed inside the gear 12. The upper end of the transmission rod passes through the hollow ring 6 and is fixedly connected to the threaded rod 5. The transmission rod and the hollow ring 6 form a rotatable connection. The gear ring 13 is set outside the connecting pipe 1. An oil injection hole is opened on one side above the hollow ring 6, and an oil drain hole is opened on the other side below it. Lubricating oil can be injected into the hollow ring 6 through the oil injection hole. Before injecting lubricating oil, the oil drain hole can be sealed with a rubber sealing plug. After injection, the oil injection hole can be sealed with a rubber sealing plug to prevent impurities from entering. When draining oil, the pump pipe can be inserted into the oil drain hole to drain and replace the lubricating oil in the hollow ring. The lubricating oil can form an oil film on the meshing surface of the gear 12 and the gear ring 13 and the rotating part of the transmission rod, effectively isolating the metal parts from direct contact. This reduces the frictional resistance during meshing and rotation, greatly reduces wear, scratches, and even meshing damage on the surface of the parts, thereby significantly reducing overall wear and greatly extending service life.

[0033] Please see Figures 1-3 As shown, a set of drive motors 7 are installed on one side below the hollow ring 6, and the output shaft of the drive motor 7 is connected to one of the transmission rods connected to the gear 12. The drive motor 7 drives the connected transmission rod to rotate, thereby driving the corresponding gear 12 to rotate. Since the gear 12 meshes with the gear ring 13 rotatably installed inside the hollow ring 6, the rotation of a single gear 12 will drive the gear ring 13 to rotate synchronously, so that the other sets of gears 12 and the corresponding transmission rods rotate synchronously.

[0034] Please see Figures 1-2 As shown, a cap 9 is threadedly connected to one side of the dispensing port 8. The dispensing port 8 is connected to the inside of the connecting pipe 1. The threaded cap 9 can seal the dispensing port 8 when not in use to prevent dust from overflowing during the discharge process inside the connecting pipe 1.

[0035] Please see Figure 1 As shown, the air inlet pipe 10 is connected to the internal of the connecting pipe 1. A filter plate 15 is installed on the front side of the air collection hood 11. Multiple sets of filter holes are opened on the surface of the filter plate 15. When the dusty and smoke-containing air in the building passes through the filter plate 15, the filter holes on its surface filter out large particulate impurities.

[0036] In practical use, the working principle of this utility model is as follows:

[0037] In use, it can be transported manually or by a forklift or other conveying equipment. After arriving at the site, the bottom cover 3 is precisely placed over the pre-drilled hole below. Then, the drive motor 7 below the hollow ring 6 (which can be connected to a controller and powered) is started. Its output shaft drives the connected transmission rod to rotate, which in turn drives the corresponding gear 12 to rotate. Since the gear 12 meshes with the gear ring 13 that is rotatably installed inside the hollow ring 6, the rotation of a single gear 12 will drive the gear ring 13 to rotate synchronously, so that the other gears 12 and the corresponding transmission rods rotate synchronously. Since the upper end of the transmission rod is fixed to the threaded rod 5, the four sets of threaded rods 5 rotate synchronously with the transmission rod. Combined with the cooperation between the threaded rod 5 and the threaded hole in the lifting rod 4 below the top cover 2, the lifting rod 4 drives the top cover 2 to rise vertically along the outside of the connecting pipe 1 until the rubber anti-slip ring on the upper surface of the top cover 2 is tightly pressed against the wall of the upper floor. At the same time, the top cover 2 is placed over the outside of the pre-drilled hole above, and works with the bottom cover 3 to achieve synchronous protection of the upper and lower holes. The rubber anti-slip ring can enhance the friction of the contact surface and improve the stability of the fixation.

[0038] After the device is installed, the connecting pipe 1 keeps the upper and lower holes vertically connected. When vertically transporting flexible pipelines, small tools or materials, ropes and straps can be used to hoist them down for transport, and they can be directly sent into the connecting pipe 1 through the upper hole. If the device is also installed in the upper hole, the corresponding pick-up and put-out port 8 can be opened and the material can be put in through the pick-up and put-out port 8 for transfer. After the item arrives at the target floor, the pick-up and put-out port 8 of that floor can be unscrewed and the cap 9 can be opened. The material in the connecting pipe 1 can be taken out through the pick-up and put-out port 8. After use, tighten the cap 9 to ensure that the connecting pipe 1 is relatively closed.

[0039] When it is necessary to purify the construction environment, the air intake fan 14 inside the air collection hood 11 is activated (it can be powered on). The dusty and smoke-laden air inside the building is filtered through the filter holes on the surface of the air filter plate 15 to remove large particles of impurities. It then enters the air collection hood 11 and the air intake pipe 10 in sequence, and finally flows into the connecting pipe 1. When the multiple layers of holes are vertically aligned, the connecting pipes 1 of each layer will be spliced ​​together to form a complete vertical exhaust channel. The final exhaust hole can be connected to the ventilation port that transmits to the outside through the pipe, so that the smoke and dust of each layer can be collected into the channel and discharged, realizing the emission of smoke and dust, effectively avoiding stagnation, and improving the air quality of the construction area.
