Description

Technical Field

[0001] This utility model relates to the field of pump station construction technology, specifically to a pre-embedded lifting ring structure for preventing falls. Background Technology

[0002] In the construction of water conservancy projects and urban water supply and drainage systems, large pumping stations serve as core hub facilities, and their installation quality directly determines the system's operational efficiency, safety, stability, and service life. Currently, the construction of large pumping stations shows a trend of "expanded scale, integrated equipment, and multifunctional components," with the number of embedded parts reaching hundreds to thousands, covering dozens of types such as bolt assemblies, lifting rings, pipe interfaces, and electrical grounding terminals.

[0003] Embedded lifting rings used in large pumping stations are critical safety components, primarily used for hoisting large equipment (such as pumps, motors, valves, etc.) during installation, inspection, and maintenance within the pump house. They must be precisely embedded before the concrete structure is poured, ensuring sufficient strength and reliability to withstand the expected hoisting loads. Because half of the embedded lifting ring is made of bent steel bars, its overall shape is "T," making it difficult to insert into the pre-reinforced steel columns, resulting in cumbersome installation. Furthermore, due to different applications and varying force directions, the stress position of the embedded lifting ring may deviate from its center, posing a risk of breakage. Therefore, we propose a fall-prevention embedded lifting ring structure. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a pre-embedded lifting ring structure for preventing falls. By matching the tension in different directions through the rotation of the lifting ring, the force position is always located in the middle of the ring's arc, reducing the possibility of breakage due to excessive force on the lifting ring. At the same time, the split pre-embedded steel bars are easy to fix, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pre-embedded lifting ring structure for preventing falls, comprising a hexagonal platform; Hexagonal platform: Both its left and right sides are connected to embedded steel bars by nuts. A connecting column is rotatably connected to the middle of the hexagonal platform. The lower end of the connecting column is equipped with a lifting ring seat. The lifting ring seat is located at the lower end of the hexagonal platform. The lower end of the lifting ring seat is rotatably connected to a lifting ring by a pin. By rotating the lifting ring, different directions of tension are matched, so that the force position is always located in the middle of the lifting ring arc, reducing the possibility of breakage due to excessive force on the lifting ring. At the same time, the split embedded steel bars are easy to fix.

[0006] Furthermore, a ring is fixedly fitted onto the upper end of the connecting post, and the ring is located inside the through hole of the hexagonal platform to prevent the connecting post from falling off.

[0007] Furthermore, an umbrella-shaped platform is provided between the lower end of the connecting column and the upper surface of the lifting ring seat to increase the force-bearing area at the connection position between the connecting column and the lifting ring seat.

[0008] Furthermore, the front and rear sides of the hexagonal platform are bolted with reinforcing claws, and the lower surface of the disc of the lifting ring seat is slidably connected to the upper surface of the transverse plate of the reinforcing claw, thereby improving the tensile strength of the lifting ring seat.

[0009] Furthermore, a positioning piece is inserted between the vertical bars of the two pre-embedded steel bars. The positioning piece is an I-shaped positioning piece, which positions the distance between the two pre-embedded steel bars.

[0010] Furthermore, the positioning piece has evenly distributed fixing grooves at both ends to prevent the tie wire from detaching from the positioning piece.

[0011] Furthermore, the lower end of the hexagonal platform is provided with evenly distributed arc-shaped grooves, and the nuts for fixing the pre-embedded steel bars are located inside the adjacent arc-shaped grooves, making it easy to tighten the nuts.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This pre-embedded lifting ring structure for fall protection has the following advantages: 1. The two embedded reinforcing bars are L-shaped, allowing them to be easily inserted into the pre-tied reinforcing column. I-shaped positioning clips ensure the vertical spacing between the two embedded reinforcing bars remains constant. These clips are fixed between two parallel reinforcing bars in the column, preventing excessive deviation and facilitating installation. 2. The connecting column and the lifting ring seat form a whole that rotates along the Z-axis inside the hexagonal platform. The lifting ring can rotate along the X-axis at the lower end of the lifting ring seat. The rotation in both directions allows the lifting ring to automatically rotate to match the direction of the force after being subjected to force, avoiding large differences in the force conditions at different positions of the lifting ring and enhancing stability.

[0015] 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.

[0016] Please see Figure 1-3 This embodiment provides a technical solution: a pre-embedded lifting ring structure for preventing falls, including a hexagonal platform 1; Hexagonal platform 1: Embedded steel bars 2 are connected to its left and right sides via nuts. A connecting column 3 is rotatably connected to the middle of the hexagonal platform 1. A lifting ring seat 4 is located at the lower end of the connecting column 3. A lifting ring 5 is rotatably connected to the lower end of the lifting ring seat 4 via a pin. A circular ring 7 is fixedly fitted onto the upper end of the connecting column 3, located inside the through hole of the hexagonal platform 1. An umbrella-shaped platform 6 is provided between the lower end of the connecting column 3 and the upper surface of the lifting ring seat 4. Reinforcing claws 8 are bolted to both the front and rear sides of the hexagonal platform 1. The lower surface of the disc of the lifting ring seat 4... The upper surface of the transverse plate of the reinforcing claw 8 is slidably connected. A positioning piece 9 is inserted between the vertical bars of the two pre-embedded steel bars 2. The positioning piece 9 is an I-shaped positioning piece. The left and right ends of the positioning piece 9 are provided with evenly distributed fixing grooves 10. The lower end of the hexagonal platform 1 is provided with evenly distributed arc-shaped grooves 11. The nuts for fixing the pre-embedded steel bars 2 are located inside the adjacent arc-shaped grooves 11. During pre-embedding, the two pre-embedded steel bars 2 are placed inside the tied steel bars respectively, and the positioning piece 9 is inserted between the two pre-embedded steel bars 2. The positioning piece 9 is an I-shaped positioning piece that can fix the steel bars. Between two adjacent reinforcing bars, to prevent the positioning piece 9 from flipping, the fixing grooves 10 on both sides of the positioning piece 9 facilitate the fixing of the binding strip of the positioning piece 9, preventing the binding strip from slipping off the positioning piece 9. Then, the threads at the lower ends of the two pre-embedded reinforcing bars 2 are wrapped with plastic to prevent contamination of the threaded parts during the pouring process. When installing the lifting ring 5, after inserting the whole assembly of the connecting column 3 and the lifting ring seat 4 into the round hole of the hexagonal platform 1, the ring 7 is welded to the upper end of the connecting column 3 to prevent the connecting column 3 from detaching from the hexagonal platform 1. The umbrella-shaped platform 6 increases the contact area at the connection position between the connecting column 3 and the lifting ring seat 4, increasing... The large bearing area reduces the possibility of breakage at the connection between the connecting column 3 and the lifting ring seat 4. The reinforcing claw 8 is installed on the front and rear sides of the hexagonal platform 1 by bolts. The disc of the lifting ring seat 4 is located between the transverse plate of the reinforcing claw 8 and the lower surface of the hexagonal platform 1, which improves the tensile strength of the lifting ring seat 4. Finally, the whole assembly consisting of the connecting column 3 and the lifting ring seat 4, as well as the hexagonal platform 1 with the reinforcing claw 8, is inserted between two pre-embedded steel bars 2 and fixed with nuts. The nuts are located inside the adjacent arc-shaped grooves 11, which increases the space for the nuts and makes it easier to tighten them.

[0017] The working principle of the pre-embedded lifting ring structure for preventing falls provided by this utility model is as follows: During pre-embedding, two pre-embedded steel bars 2 are placed inside the tied steel bars respectively, and a positioning piece 9 is inserted between the two pre-embedded steel bars 2. The positioning piece 9 is an I-shaped positioning piece, which can be fixed between two adjacent steel bars to prevent the positioning piece 9 from flipping. The fixing grooves 10 on both sides of the positioning piece 9 facilitate the fixing of the binding strip of the positioning piece 9 to prevent the binding strip from slipping off the positioning piece 9. Then, the threads at the lower ends of the two pre-embedded steel bars 2 are wrapped with plastic to prevent contamination of the threaded parts during the casting process. When installing the lifting ring 5, after the whole assembly of the connecting column 3 and the lifting ring seat 4 is inserted into the round hole of the hexagonal platform 1, the ring 7 is welded to the upper end of the connecting column 3 to prevent the connecting column 3 from detaching from the hexagonal platform 1. (The connecting column 3 and the lifting ring seat 4 are integrally formed by casting, or the connecting column 3 and the ring 7 can also be integrally formed by casting, and the lifting ring seat 4 and the connecting column 3 are fixed by welding.) Alternatively, the lower end of the connecting column 3 can be equipped with a stud, and the middle of the lifting eye seat 4 can be provided with a through hole. After the stud passes through the through hole, it can be fixed with a fixing nut. The umbrella-shaped platform 6 increases the contact area between the connecting column 3 and the lifting eye seat 4, increases the stress area, and reduces the possibility of breakage at the connection point between the connecting column 3 and the lifting eye seat 4. The reinforcing claw 8 is installed on the front and rear sides of the hexagonal platform 1 with bolts. The disc of the lifting eye seat 4 is located between the transverse plate of the reinforcing claw 8 and the lower surface of the hexagonal platform 1, which improves the tensile strength of the lifting eye seat 4. Finally, the hexagonal platform 1, which is composed of the connecting column 3 and the lifting eye seat 4 and the reinforcing claw 8, is inserted between two pre-embedded steel bars 2 and fixed with nuts. The nuts are located inside the adjacent arc-shaped grooves 11, which increases the space for the nuts and makes it easier to tighten them. The upper surface of the hexagonal platform 1 is in contact with the surface of the cast wall, and the upper surface of the hexagonal platform 1 is a regular hexagon, which has a larger contact area with the wall and a larger stress area.

[0018] It is worth noting that the microcontroller 4 disclosed in the above embodiments can be a PIC16F1823-I / P model microcontroller, and the data storage 5 and micro switch 63 can be freely configured according to the actual application scenario. The control switch group controls the operation of the fan 2 and the motor 31 using methods commonly used in the prior art. The control switch group 10 is equipped with switch buttons corresponding to the motor 21, the second motor 71 and the push rod 32 for controlling their switching operation.
