Description

Technical Field

[0001] This utility model relates to the field of sealing installation technology, specifically to a floating seal installation device for an underwater pump shaft assembly. Background Technology

[0002] The submersible pump shaft assembly is a crucial component of the submersible pump, consisting of the pump shaft, bearings, shaft sleeve, and mechanical seal. The pump shaft is typically made of high-strength stainless steel and is used to transmit power, connecting the motor and impeller to drive water flow. The bearings support the pump shaft and reduce friction; the shaft sleeve protects the pump shaft and assists in sealing; the mechanical seal prevents liquid leakage. During the production and assembly process, a floating oil seal is required to ensure the sealing performance of the submersible pump shaft assembly.

[0003] The diameter of the floating oil seal is usually the same as the diameter of the pipe opening to ensure a tight seal. However, when the diameter of the floating oil seal is the same as the pipe opening, during installation, the floating oil seal needs to be bent, and one side needs to be inserted into the pipe opening first. Then, the floating oil seal needs to be unfolded, and the edge of the floating oil seal needs to be pressed into the pipe opening little by little. When only the last bit is left, which is also the most difficult part to insert into the pipe opening, it is usually hammered to force the floating oil seal into the pipe opening. This method is time-consuming and laborious, and there is a high risk of deviation or injury to the operator during hammering. Utility Model Content

Detailed Implementation

[0039] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0040] like Figures 1-4As shown, this embodiment proposes a floating seal installation device for an underwater pump shaft assembly, including: a fixed plate 1, clamping rods 2, a lower pressure plate 3, a clamping mechanism, and a lower pressure mechanism. Multiple connecting seats 18 are fixedly connected to the bottom end of the fixed plate 1, and multiple clamping rods 2 are rotatably connected within the multiple connecting seats 18. Two hand-held brackets 17 are fixedly connected to the top end of the fixed plate 1. Multiple rotating seats 16 are fixedly connected to the rotating bracket 9, and multiple lower pressure wheels 10 are rotatably connected within the multiple rotating seats 16. Multiple sliding rods 14 are fixedly connected to the fixed plate 1. Multiple slip rings 15 are fixedly connected to the pressure plate 3. The slip rings 15 are slidably connected to multiple slide rods 14. Multiple clamping rods 2 are provided. The clamping rods 2 are rotatably connected to the bottom end of the fixed plate 1. The lower pressure plate 3 is slidably connected to the bottom end of the fixed plate 1. Through the cooperation between the fixed plate 1, clamping rods 2, lower pressure plate 3, clamping mechanism and lowering mechanism, it is convenient to press the entire floating oil seal parallel down when installing the floating oil seal. The floating oil seal can be pressed into the pipe port quickly and flatly, which is more time-saving and labor-saving, and has a lower risk.

[0041] The clamping mechanism is mounted on the fixed plate 1 and is used to drive the clamping rods 2 to clamp the position where the floating oil seal needs to be installed. The clamping mechanism includes: clamping blocks 4, transmission rods 5 and a drive assembly. Clamping blocks 4 are fixedly connected to multiple clamping rods 2, and transmission rods 5 are rotatably connected to multiple clamping rods 2. The drive assembly is mounted on the fixed plate 1 and is used to drive multiple transmission rods 5 to move. The drive assembly includes: a drive plate 6 and a first electric cylinder 7. The drive plate 6 is rotatably connected to the top of multiple transmission rods 5. The first electric cylinder 7 is mounted on the fixed plate 1. The output end of the first electric cylinder 7 passes through the fixed plate 1 and is fixedly connected to the drive plate 6. Specifically, the first electric cylinder 7 drives the drive plate 6 to rise. When the drive plate 6 rises, it drives the bottom ends of multiple transmission rods 5 to move closer to each other, thereby driving multiple clamping rods 2 and clamping blocks 4 to clamp and fix the pipe opening.

[0042] The pressing mechanism is mounted on the pressing plate 3 and is used to press down and install the floating oil seal. The pressing mechanism includes a second electric cylinder 8, a rotating frame 9, and a pressing and rotating assembly. A through hole matching the second electric cylinder 8 is provided on the fixed plate 1. The second electric cylinder 8 is mounted on the top of the drive plate 6, and its output end passes through the drive plate 6 and is fixedly connected to the pressing plate 3. The rotating frame 9 is rotatably connected to the pressing plate 3. Multiple pressing wheels 10 are provided, and all pressing wheels 10 are rotatably connected to the bottom end of the rotating frame 9. The rotating assembly is mounted on the pressing plate 3 and is used to drive the rotating frame 9 to rotate. The rotating assembly includes a rotating gear 11, a drive gear 12, and a first motor 13. The rotating gear 11 is fixedly connected to the first motor 13. On the rotating frame 9, the drive gear 12 is rotatably connected to the lower pressure plate 3. The drive gear 12 meshes with the rotating gear 11. The first motor 13 is mounted on the lower pressure plate 3. The output end of the first motor 13 passes through the lower pressure plate 3 and is fixedly connected to the drive gear 12. Specifically, the lower pressure plate 3 is driven to descend by the second electric cylinder 8 set on the drive plate 6, so that the lower pressure wheel 10 contacts the floating oil seal. Then, the first motor 13 drives the drive gear 12 and the rotating gear 11 to rotate, which in turn drives the rotating frame 9 to rotate. When the rotating frame 9 rotates, it drives multiple lower pressure wheels 10 to roll along the floating oil seal. At this time, the second electric cylinder 8 continues to press down, thereby quickly pressing the floating oil seal into the pipe opening.

[0043] In this embodiment, when it is necessary to install the floating oil seal inside the pipe opening, the floating oil seal is placed at the pipe opening. Then, the first electric cylinder 7 drives the drive plate 6 to rise. When the drive plate 6 rises, it drives the bottom ends of multiple transmission rods 5 to move closer to each other, thereby driving multiple clamping rods 2 and clamping blocks 4 to clamp and fix the pipe opening. The second electric cylinder 8 on the drive plate 6 drives the lower pressure plate 3 to descend, thereby causing the lower pressure roller 10 to contact the floating oil seal. Then, the first motor 13 drives the drive gear 12 and the rotating gear 11 to rotate, thereby driving the rotating frame 9 to rotate. When the rotating frame 9 rotates, it drives multiple lower pressure rollers 10 to roll along the floating oil seal. At this time, the second electric cylinder 8 continues to press down, thereby quickly pressing the floating oil seal into the pipe opening.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
