Description

Technical Field

[0001] This utility model relates to the field of pump body technology, specifically a novel large-scale high-pressure pump body structure. Background Technology

[0002] High-pressure pumps are an important component of dredgers. They provide high-pressure power for high-pressure jet slurry. The pump casing of a high-pressure pump is generally manufactured by casting. Casting reduces the need for welding repairs, thereby improving the sealing and pressure-bearing performance of the pump body.

[0003] The existing high-pressure pump body structure has a fixed and unadjustable position for the inlet and outlet after installation. This results in poor flexibility when connecting the pump body to the water pipe, making it impossible to adjust the pump body's position according to the actual connection situation. The entire pump body needs to be disassembled for adjustment, which is very inconvenient and makes the high-pressure pump body difficult to use. Utility Model Content

[0004] The purpose of this utility model is to provide a novel large-scale high-pressure pump body structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a novel large high-pressure pump body structure, including a pump casing, an inlet pipe and an outlet pipe fixedly connected to the pump casing, and an installation mechanism installed on the vertical side wall of the pump casing.

[0007] The mounting mechanism includes two threaded columns symmetrically fixedly connected to the vertical outer wall of the pump casing. An arc-shaped plate is mounted on each of the two threaded columns, and an arc-shaped hole is formed on the arc-shaped plate. The two threaded columns pass through the arc-shaped hole and pass through the arc-shaped plate. A locking nut is threaded onto each threaded column. Multiple toothed blocks are evenly fixedly connected to the upper side of the arc-shaped plate. A locking assembly is fixedly connected to the vertical outer wall of the pump casing. The locking assembly is located above the arc-shaped plate and includes a mounting plate fixedly connected to the vertical outer wall of the pump casing. The mounting plate has a threaded hole, and an adjusting screw is threaded into the threaded hole. A connecting plate is fixedly connected to the lower side of the arc-shaped plate. An L-shaped plate is fixedly connected to the lower side of the connecting plate. Multiple mounting blocks are fixedly connected to the vertical side wall of the L-shaped plate, and pin holes are formed on the mounting blocks.

[0008] Furthermore, a connecting rod is fixedly connected to the lower end of the adjusting screw, and a locking block is rotatably sleeved on the wall of the connecting rod through a bearing. The locking block is located between two adjacent tooth blocks, and two limiting rods are symmetrically fixedly connected to the upper side of the locking block. Two limiting holes are symmetrically opened on the mounting plate, and the limiting rods pass through the limiting holes and penetrate the mounting plate.

[0009] Furthermore, each of the two threaded posts is movably fitted with a limiting washer, which is located between the locking nut and the arc-shaped plate.

[0010] Furthermore, an arc-shaped support plate is fixedly connected to the vertical side wall of the L-shaped plate. The arc-shaped support plate is located below the pump casing, and the upper side of the arc-shaped support plate is tightly fitted to the bottom of the pump casing.

[0011] Furthermore, a reinforcing rib is fixedly connected between the vertical sidewall and the horizontal sidewall of the L-shaped plate, and a connecting rib is fixedly connected between the reinforcing rib and the L-shaped plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model, through its installation mechanism, allows for the installation of the pump casing. An arc-shaped plate is fitted onto two threaded posts, and the arc-shaped plate is secured using locking nuts and a locking assembly. Bolts are then used to fix the mounting block, completing the fixed installation of the pump casing. To adjust the orientation of the inlet and outlet pipes, the two locking nuts are loosened, releasing their constraint on the arc-shaped plate. The adjusting screw is then turned, and through the threaded engagement between the screw and the threaded hole, it moves away from the toothed block, thus releasing the constraint on the arc-shaped plate and consequently the pump casing. Rotating the pump casing allows for adjustment of the orientation of the inlet and outlet pipes, enabling flexible adjustment of the water inlet and outlet directions according to actual connection requirements. This eliminates the need to disassemble the entire pump body, effectively improving the convenience of pump use. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-5 This utility model provides a novel large-scale high-pressure pump body structure, including a pump casing 1. The pump casing 1 is fixedly connected to an inlet pipe 2 and an outlet pipe 3. An installation mechanism 4 is installed on the vertical side wall of the pump casing 1. The pump casing 1 is produced by a whole sample plus core assembly method. The outer shape is a whole sample shape, and the inner cavity is a whole core. Special anti-crack ribs are set for the parts of the pump casing 1 and flange 26 that are prone to cracking due to the large difference in thickness. The inner cavity of the pump casing 1 has a large difference in thickness, and open chills and closed risers and shrinkage channels are set for zoned shrinkage. The junction of the hot joint at the foot of the pump casing 1 is set with an inner chill and a round steel closed chill to achieve sequential shrinkage. The core head of the inner cavity of the pump casing 1 and the core head of the sample are made of steel structure hard points to prevent sinking. The core skeleton is made of reinforced steel structure to ensure that it is not lifted during lifting, transportation and casting process.

[0025] The mounting mechanism 4 includes two threaded posts 5 symmetrically fixedly connected to the vertical outer wall of the pump casing 1. An arc-shaped plate 6 is mounted on the two threaded posts 5. An arc-shaped hole 7 is opened on the arc-shaped plate 6. The two threaded posts 5 pass through the arc-shaped hole 7 through the arc-shaped plate 6. A locking nut 8 is threadedly fitted on the threaded post 5. A plurality of toothed blocks 9 are evenly fixedly connected to the upper side of the arc-shaped plate 6. A locking assembly 10 is fixedly connected to the vertical outer wall of the pump casing 1. The locking assembly 10 is located above the arc-shaped plate 6. The locking assembly 10 includes a mounting plate 11 fixedly connected to the vertical outer wall of the pump casing 1. A threaded hole is opened on the mounting plate 11, and an adjusting screw 12 is threadedly fitted into the threaded hole. A connecting plate 13 is fixedly connected to the lower side of the arc-shaped plate 6. An L-shaped plate 14 is fixedly connected to the lower side of the connecting plate 13. A plurality of mounting blocks 15 are fixedly connected to the vertical side wall of the L-shaped plate 14. A pin hole 16 is opened on the mounting block 15.

[0026] In the above embodiment, when installing the pump housing 1, the arc-shaped plate 6 is fitted onto the two threaded posts 5, and the arc-shaped plate 6 is fixed by the locking nut 8 and the locking assembly 10. The mounting block 15 is fixed by bolts to complete the fixed installation of the pump housing 1. When it is necessary to adjust the orientation of the inlet pipe 2 and the outlet pipe 3, the two locking nuts 8 are loosened to release the limiting fixation of the arc-shaped plate 6 by the two locking nuts 8. The adjusting screw 12 is turned, and through the threaded engagement between the adjusting screw 12 and the threaded hole, the adjusting screw 12 is moved away from the toothed block 9, thereby releasing the limiting fixation of the arc-shaped plate 6 and the pump housing 1. The orientation of the inlet pipe 2 and the outlet pipe 3 on the pump housing 1 can be adjusted by rotating the pump housing 1. Thus, the inlet and outlet directions of the pump housing 1 can be flexibly adjusted according to the actual connection requirements without disassembling the entire pump body for operation, which effectively improves the convenience of using the pump body.

[0027] The lower end of the adjusting screw 12 is fixedly connected to a connecting rod 17. The rod wall of the connecting rod 17 is rotatably sleeved with a locking block 18 through a bearing. The locking block 18 is located between two adjacent toothed blocks 9. Two limiting rods 19 are symmetrically fixedly connected to the upper side of the locking block 18. Two limiting holes 20 are symmetrically opened on the mounting plate 11. The limiting rods 19 pass through the limiting holes 20 and penetrate the mounting plate 11. In use, the adjusting screw 12 is turned. Through the threaded engagement between the adjusting screw 12 and the threaded hole, the adjusting screw 12 moves. And through the limiting rods 19 limiting the locking block 18, the adjusting screw 12 can drive the locking block 18 to move, so that the locking block 18 can be engaged with or disengaged from the toothed block 9. This can realize the locking or unlocking of the arc plate 6, and improve the stability and convenience of fixing the pump housing 1.

[0028] Both threaded posts 5 are movably fitted with limiting washers 21. The limiting washers 21 are located between the locking nut 8 and the arc plate 6. The limiting washers 21 can improve the fixing effect of the locking nut 8 on the arc plate 6.

[0029] An arc-shaped support plate 22 is fixedly connected to the vertical side wall of the L-shaped plate 14. The arc-shaped support plate 22 is located below the pump housing 1, and the upper side of the arc-shaped support plate 22 is closely fitted to the bottom of the pump housing 1. The arc-shaped support plate 22 can support and limit the pump housing 1, thereby improving the stability of the pump housing 1.

[0030] A reinforcing rib 23 is fixedly connected between the vertical sidewall and the horizontal sidewall of the L-shaped plate 14, and a connecting rib 24 is fixedly connected between the reinforcing rib 23 and the L-shaped plate 14. The reinforcing rib 23 and the connecting rib 24 can improve the structural strength of the L-shaped plate 14 and improve the stability of the pump casing 1 installation.

[0031] The upper side of the locking block 18 is provided with a shaft hole 25, and the lower end of the connecting rod 17 is located in the shaft hole 25. The connecting rod 17 is rotatably connected to the hole wall of the shaft hole 25 through a bearing. The shaft hole 25 can improve the stability of the connection between the connecting rod 17 and the locking block 18.

[0032] The height of the lower side of the mounting block 15 is lower than the height of the bottom of the L-shaped plate 14, which allows for a gap between the L-shaped plate 14 and the mounting surface during installation, thereby improving the adaptability of the L-shaped plate 14 to the mounting surface during installation.

[0033] Flanges 26 are fixedly fitted on both the inlet pipe 2 and the outlet pipe 3. The inlet pipe 2 has an L-shaped structure. The flanges 26 can improve the convenience of connecting the inlet pipe 2 and the outlet pipe 3 to the pipeline. The L-shaped structure of the inlet pipe 2 can change the water inlet direction, thereby increasing the space for pipeline installation.

[0034] Working principle: When installing the pump casing 1, the arc-shaped plate 6 is fitted onto the two threaded posts 5, and the arc-shaped plate 6 is fixed by the locking nuts 8 and the locking assembly 10. The mounting block 15 is fixed by bolts to complete the fixed installation of the pump casing 1. When it is necessary to adjust the orientation of the inlet pipe 2 and the outlet pipe 3, loosen the two locking nuts 8 to release the limiting fixation of the arc-shaped plate 6. Turn the adjusting screw 12. Through the threaded engagement between the adjusting screw 12 and the threaded hole, the adjusting screw 12 moves away from the toothed block 9, thereby releasing the limiting fixation of the arc-shaped plate 6 and the pump casing 1. Rotating the pump casing 1 can adjust the orientation of the inlet pipe 2 and the outlet pipe 3 on the pump casing 1. This allows for flexible adjustment of the inlet and outlet directions of the pump casing 1 according to actual connection requirements, without having to disassemble the entire pump body for operation, effectively improving the convenience of pump body use.
