Description

Technical Field

[0001] This utility model relates to the field of bolt tensioning technology, specifically an automated bolt lifting device for hot-dip galvanizing process. Background Technology

[0002] In the field of mechanical assembly, bolts are undoubtedly indispensable key components. Their fastening method offers numerous significant advantages. Compared to other methods, they are not only more robust and reliable, effectively ensuring the stability and safety of the connection, but also extremely convenient to implement, requiring no complex procedures or specialized equipment. Furthermore, from a cost perspective, bolt fastening offers a clear advantage, reducing assembly costs. For these reasons, bolts have become the most commonly used connecting component in the mechanical field, widely applied in various scenarios requiring the tight fixing of two or more components together, providing a solid foundation for the normal operation of mechanical devices.

[0003] However, current automated bolt lifting devices are typically only suitable for tightening a single type of nut. This means that when dealing with tightening different types of nuts, multiple nut retainers are often required, limiting the device's versatility and convenience. Therefore, existing automated lifting devices cannot be flexibly applied to diverse nut tightening needs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automated bolt lifting device for hot-dip galvanizing processes, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automated bolt lifting device for hot-dip galvanizing process includes a chassis, a nut retaining ring inside the chassis, a plurality of mounting holes on the outer wall of the nut retaining ring, and fixing bolts threaded into the interior of the plurality of mounting holes, the fixing bolts being distributed in a circular pattern, and a plurality of fastening holes on the outer wall of the nut retaining ring.

[0007] Preferably, a bolt fixing sleeve is provided above the nut fixing ring, and an installation ring is connected to the outer wall of the bolt fixing sleeve. The outer wall of the installation ring is provided with several fastening holes.

[0008] Preferably, the top surface of the chassis is provided with a hydraulic tensioning body, and the top surface of the hydraulic tensioning body is in contact with the bottom surface of the mounting ring.

[0009] Preferably, an air supply pipe is fixedly connected to the outer wall of the hydraulic tensioning body, one end of the air supply pipe is connected to a pressure injector, and a pressure gauge is installed on the outer wall of the air supply pipe.

[0010] Preferably, one end of each of the fixing bolts is connected to a fixing plate, and one side of each of the fixing plates is connected to an anti-slip block.

[0011] Preferably, a through hole is provided on the outer wall of the chassis, and the through hole is arc-shaped.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In actual operation, workers place the nut retaining ring onto the outer wall of the nut to be tightened, and then rotate the fixing bolt at different positions to achieve a secure fixation of the nut. Because different types of nuts differ in size and structure, this design ensures that the fixing bolt is firmly fixed to different types of nuts. It eliminates the need to change nut holders of different models, thus completing the fixing work for various types of nuts, greatly improving work efficiency, saving time and labor costs, and bringing great convenience to related operations.

[0014] 2. An anti-slip block is connected to one side of the fixing plate, preventing the fixing bolt from rotating or slipping during the tightening of the nut. The anti-slip block enhances the friction between the fixing plate and the operating interface, ensuring that the fixing bolt maintains a stable point of force when tightening, thereby effectively fixing the nut and improving the accuracy and reliability of the tightening operation.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: an automated bolt lifting device for hot-dip galvanizing process, including a chassis 1, a nut fixing ring 2 is provided inside the chassis 1, a plurality of mounting holes 3 are provided on the outer wall of the nut fixing ring 2, and fixing bolts 4 are threadedly connected to the interior of the plurality of mounting holes 3 respectively, the fixing bolts 4 are distributed in a circle, and a plurality of fastening holes 5 are provided on the outer wall of the nut fixing ring 2.

[0022] More specifically, the worker places the nut retaining ring 2 onto the outer wall of the nut to be tightened, and securely fixes the nut by rotating the fixing bolts 4 at different positions. Because different types of nuts differ in size and structure, this design ensures that the fixing bolts 4 are firmly fixed to nuts of different types.

[0023] In this utility model, a bolt fixing sleeve 6 is provided above the nut fixing ring 2, and an installation ring 7 is connected to the outer wall of the bolt fixing sleeve 6. Several fastening holes 5 are provided on the outer wall of the installation ring 7.

[0024] More specifically, the bolt fixing sleeve 6 fixes the bolts that need to be tightened, stretches the bolts, and thus tightens the nuts at the bottom.

[0025] In this utility model, a hydraulic tensioning body 8 is provided on the top surface of the chassis 1, and the top surface of the hydraulic tensioning body 8 is in contact with the bottom surface of the mounting ring 7.

[0026] More specifically, when hydraulic fluid enters the working chamber through the supply port, it applies pressure within the chamber, causing the piston or other moving parts inside to move outward. After the hydraulic pump starts, it draws hydraulic oil from the tank and pushes it into the hydraulic cylinder. As the pressure inside the hydraulic cylinder increases, the hydraulic piston begins to move, applying tension to the workpiece, thereby lifting the bolt. The nut below the bolt, which needs to be tightened, can then be rotated and secured.

[0027] In this utility model, an air supply pipe 9 is fixedly connected to the outer wall of the hydraulic tensioning body 8, one end of the air supply pipe 9 is connected to a pressure booster 10, and a pressure gauge 11 is installed on the outer wall of the air supply pipe 9.

[0028] More specifically, high-pressure gas is injected into the gas supply pipe 9 through the pressure injector 10. This gas is then transmitted to the hydraulic tensioning body 8 through the gas supply pipe 9, thereby generating pressure inside the hydraulic tensioning body 8 to achieve the function of stretching or compressing. At the same time, the pressure gauge 11 is used to monitor and display the system pressure to ensure operational safety.

[0029] In this utility model, one end of several fixing bolts 4 is respectively connected to a fixing plate 12, and one side of several fixing plates 12 is respectively connected to an anti-sliding block 13.

[0030] More specifically, during the tightening of the nut, the fixing bolt 4 will not rotate or slip due to force. The anti-slip block 13 can enhance the friction between the fixing plate 12 and the operating interface, ensuring that the fixing bolt 4 maintains a stable point of force when tightening, thereby effectively fixing the nut and improving the accuracy and reliability of the tightening operation.

[0031] In this utility model, a through hole 14 is provided on the outer wall of the chassis 1, and the through hole 14 is arc-shaped.

[0032] More specifically, the through hole 14 is designed so that a wrench can be inserted through the through hole 14 into the fastening hole 5 on the outer wall of the nut retaining sleeve, and then rotated to complete the tightening of the nut.

[0033] Working principle: First, the operator places the nut retaining ring 2 onto the outer wall of the nut to be tightened. The nut is then securely fixed by rotating the fixing bolts 4 at different positions. Next, the base plate 1 is placed on the nut retaining ring 2, and the hydraulic tensioning body 8 is placed on the base plate 1. Then, the bolt fixing sleeve 6 is threaded onto the bolt. A wrench is inserted into the tightening hole 5 on the outer wall of the mounting ring 7, and the wrench is rotated to firmly fix the device. After the device is fixed, gas is injected into the hydraulic tensioning body 8 using the pressure injector 10. As the pressure increases, the bolt fixing sleeve 6 is lifted. The wrench is then inserted through the through hole 14 into the tightening hole 5 on the outer wall of the nut retaining ring 2 and rotated, thus completing the tightening of the nut. This device is suitable for nuts of different sizes and types, increasing its application range in various situations.
