Description

Technical Field

[0002] Ductile iron pipes are generally produced using blast furnace iron as raw material. The blast furnace iron is heated and tempered in an induction furnace, then subjected to magnesium spraying and spheroidization treatment. The spheroidization grade of the molten iron is controlled to be 1-3. After centrifugal casting, it undergoes annealing, zinc spraying, finishing, lining, curing, cement internal grinding, external wall coating, and marking processes. Ductile iron pipes possess the inherent qualities of iron and the performance of steel, while also being easy and quick to install, making them the ideal choice for water pipelines and thus widely used.

[0003] Chinese Patent No. CN220787807U discloses a lifting device for ductile iron pipes, including a lifting beam with lifting plates at both ends. Each lifting plate is hinged with a lifting hook. The lifting hook is connected to a power mechanism mounted on the lifting beam via a transmission component. Driven by the power mechanism, the transmission component moves to adjust the state of the lifting hook. This invention enables rapid lifting of ductile iron pipes, has a simple structure, is easy to operate, and is highly practical.

[0004] During the lifting operation of ductile iron pipes, due to the weight and volume of the pipes, special attention needs to be paid to the selection of lifting points and the rationality of the lifting method. As a result, existing lifting tools are not convenient for adjusting the lifting connection position according to the lifting point, which may lead to deformation or damage of the ductile iron pipes during the lifting process, thereby reducing the safety and efficiency of the lifting, and increasing the lifting cost and risk.

[0026] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0027] Example 1

[0028] like Figure 1 - Figure 4As shown, the present invention proposes a lifting tool for ductile iron pipes, comprising: a lifting rod 1, a mounting block b2, a reinforcing component 3, and a lifting component; the lifting rod 1 is connected to the upper part of the mounting block a101, and splicing rods a102 are respectively connected to the upper two ends of the mounting block a101. The splicing rods a102 are provided with through holes a. The inner walls of the mounting block a101 and the two splicing rods a102 form a mounting cavity a. A connector a103 is connected above the mounting cavity a, and the connector a103 is connected to a hook a for connecting with a lifting machine. The mounting block b2 is connected to the lower part of the lifting rod 1; the mounting block b2 is connected to the splicing rod b201, and the splicing rod b201 and the splicing rod a102 have the same structure and are provided with through holes b, so that the inner walls of the mounting block b2 and the splicing rod b201 penetrate the mounting cavity b, and the connector b is connected to the lower part of the mounting cavity b; the reinforcing component 3 is connected to the lower part of the mounting cavity b; the lifting component is connected to the lower part of the mounting cavity b; the lifting component is set on both sides of the reinforcing component 3, so that the reinforcing component 3 cooperates to lift the ductile iron pipe body 5. The installation positions of connectors A103 and B are adjusted to facilitate the adjustment of the installation position of connector B according to the balance point of the lifting tool for ductile iron pipes. In turn, the installation position of connector A103 is adjusted according to the overall structure of the lifting tool and the connection balance point of the lifting machine. This increases the rationality of the lifting method, improves the safety and stability of the lifting operation, avoids deformation or damage to ductile iron pipes during the lifting process, and reduces the lifting cost and risk of ductile iron pipes.

[0029] To further explain, there are two connectors a103 and six connectors b, so that the number of corresponding mounting cavities a and b is the same; connectors a103 and b have the same structure; connector b includes an adjustment seat 202 connected to the bottom of mounting cavity b, the adjustment seat 202 is provided with a mounting hole, the mounting hole and the through hole b are opposite each other, and a connecting block 203 is connected below the adjustment seat 202 for connecting with the hoisting component or the reinforcement component 3. First, based on the overall lifting device structure and the stable connection of the pipe body 5, adjust the connection position of the connector b and the mounting cavity b. According to the balance point, align the through hole b and the through hole of the adjusting seat 202, and use flange bolts to install and fix them through. At the same time, the connection method of the connector a103 and the mounting cavity a is the same. According to the lifting device structure and the connection balance point of the lifting machine equipment, adjust the installation position. The connector b drives the lifting assembly and the reinforcement assembly 3 to connect to the lower position of the lifting rod 1. At the same time, adjust the distance between the lifting assembly and the reinforcement assembly 3 through the connection position of the connector b, so as to facilitate the adjustment and use according to the length of the pipe body 5 and increase the practicality of the overall lifting device structure.

[0030] Further explanation: The reinforcing component 3 includes a connecting sleeve 301, to which a rod 302 is connected. The rod 302 is connected to a bracket 303, which is connected to a reinforcing seat 304. The reinforcing seat 304 is connected to an anti-friction pad a305 for connecting the ductile iron pipe body 5. The sleeve 301 is connected to an installation component. The installation component includes an installation rod 306 connected to the sleeve 301. Splicing plates a307 are connected to both ends of the installation rod 306. A connecting block 203 is connected to the splicing plate a307, and the connection is detachable. The anti-friction pads a305 and b403 are made of the same material, using rubber or nylon rope slings to protect the ductile iron pipe body 5. The splicing plate a307 and the connecting block 203 are connected using flange bolts. The connection method for the connecting block 203 and the splicing plate b403 is the same, making operation simple and facilitating the assembly and connection of the lifting device structure.

[0031] Example 2

[0032] like Figure 1 and Figure 2 As shown, the present invention proposes a lifting tool for ductile iron pipes. Based on the above embodiments, this embodiment also details the specific components of the lifting rod 1 and the lifting assembly, as well as their matching methods.

[0033] To further explain, each end of the lifting rod 1 is connected to two connecting rods 104, and the four connecting rods 104 are connected to four hooks b105, which are used to connect the hooks a and the lifting equipment. Through the hooks b105 and hooks a, the lifting structure of the entire ductile iron pipe is connected to the lifting equipment, which facilitates the lifting and use of the ductile iron pipe body 5.

[0034] Further explanation: The lifting assembly includes four splicing plates b4, each connected to a connector a103 at both ends. Each of the four splicing plates b4 is connected to a hook 401. The four hooks 401 are paired and connected to lifting ropes 402. Each lifting rope 402 has openings at both ends for connection to the hooks 401. Each lifting rope 402 is connected to an anti-friction pad b403 for connecting to the ductile iron pipe body 5. The openings pass through the hooks 401, creating an arc-shaped connection for the lifting ropes 402, thus facilitating the lifting of the ductile iron pipe body 5.

[0035] The working principle of this utility model is as follows: When using the ductile iron pipe lifting tool, connectors a103 and b are connected to splicing plate a307 and splicing rod b201 respectively, so that splicing plate a307 drives mounting rod 306. Mounting rod 306 is connected to sleeve 301. Sleeve 301 is fitted around rod 302. Rod 302 drives bracket 303. Bracket 303 drives reinforcing seat 304. Reinforcing seat 304 is connected to pipe 5 through anti-friction pad a305. Then splicing plate b4 is connected to hook 401. Hook 401 is connected to lifting rope 402. Lifting rope 402 passes through the bottom of pipe 5, and both ends are connected to the corresponding hook 401, so that the ductile iron pipe 5 can be lifted. The reinforcing seat 304 cooperates to increase the stability of the ductile iron pipe 5 and improve the practicality of the ductile iron pipe lifting tool.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
