Description

Technical Field

[0001] The utility model belongs to the technical field of ship outfitting design, and in particular relates to a supporting structure of a large vertical pump. Background Art

[0002] With the development of ship technology, ships are getting bigger and bigger, and the power and volume of the corresponding propulsion devices are also getting bigger and bigger. As a result, the vibration of auxiliary equipment is becoming more and more obvious, especially large vertical pumps, which are heavy and have a high center of gravity. The original anti-vibration method for large vertical pumps was relatively casual and lacked dedicated fixed limiters. Therefore, a bracing structure was designed to prevent the vibration of large vertical pumps.

[0003] There are two types of anti-vibration designs for conventional large vertical pumps on ships:

[0004] Use angle steel, steel pipe and other profiles to connect the motor lifting lug and a more stable end (hull structure or iron rigging platform); use steel wire rope to connect the motor lifting lug and a more stable end (hull structure or iron rigging platform).

[0005] The first type uses steel profiles. First, this type is relatively heavy. Second, because the profile is used to directly pull the motor lifting ring, there have been several cases of motors being torn in ships in use.

[0006] The second type uses a wire rope. Since the rope is fixed in only one direction, it often needs to be tied in multiple directions. It is not beautiful, and the strength is not as good as the profile. In addition, the rope is very easy to loosen and needs to be tightened frequently. Utility Model Content

[0007] In order to solve the technical problems in the prior art, the utility model provides a support structure for a large vertical pump. The support structure itself is a rod-shaped member with a horn structure at one end, which is connected to the pump body of the pump through two bolts between the pump body and the motor bracket; the other end is connected to the hull or other fixing parts, thereby playing a fixing role.

[0008] Furthermore, the rod-shaped member of the bracing structure itself is two sleeved steel pipes, the end of one steel pipe is fixedly connected to the horn structure, and the end of the other steel pipe is connected to a hinged member connected to the hull or other fixed parts.

[0009] Furthermore, the hinged part includes a circular plate connected to the end face of the steel pipe, and a first eye plate is vertically connected to the circular plate; the hinged part also includes a second eye plate connected to the hull or other fixing parts, and the first eye plate and the second eye plate are connected by fasteners.

[0010] Furthermore, at least two bracing structures are provided around the vertical pump, and the angle between two adjacent bracing structures is ≤120° and ≥30°.

[0011] Furthermore, the two braces should avoid being arranged opposite each other.

[0012] Furthermore, as the volume of the pump increases, the number of braces is increased.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The present invention is safe, stable and durable in use, and has a simple and beautiful appearance and layout. Conventional tensioning braces are used to fix the motor lifting rings, which may cause the lifting rings to tear the motor. The present invention fixes the fasteners on the pump body and the pump motor, and each tensioning brace can hold two points of the pump, so the present invention is better in terms of safety and stability in equipment use. Compared with the wire rope tensioning type solution, the present invention does not require fastening in multiple directions, is relatively simple in space, and does not have a "tied up" feeling. The tensioning structure of the present invention, once installed, does not require subsequent maintenance, and even when the pump is overhauled, the disassembly of the tensioning structure is extremely convenient and simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 This is a structural diagram I of the present invention (main viewing angle);

[0016] Figure 2 This is a schematic diagram II of the structure of the present invention (top view);

[0017] Figure 3-Figure 5 It is a schematic diagram of a specific application scenario of the present utility model. DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0019] Reference Figure 1 This application proposes a tensioning structure for a large vertical pump: it is welded together by a ram horn structure, an elbow plate, a circular plate, and a steel pipe. A sleeve structure is used between the two steel pipes, and the length can be adjusted according to the actual situation of the application scenario before welding. The other end of the steel pipe is welded to the circular plate and the small eye plate, and the small eye plate and the large eye plate are connected by fasteners.

[0020] It solves the shortcomings of the first two commonly used types: safe and stable, beautiful appearance, and long-lasting durability.

[0021] like Figure 1 and Figure 2As shown, the bracing arrangement and use: the bracing structure itself is a rod-shaped member, one end of which is a clevis structure, connected to the pump body through two bolts between the pump body and the motor bracket; the other end is connected to the hull or other fixing parts to play a fixing role;

[0022] Reference Figure 3-Figure 5 At least two bracing structures should be installed around the vertical pump, with the angle between adjacent braces ≤ 120° and ≥ 30°. Avoid placing the two braces directly opposite each other to prevent the kinetic energy from being released during the pump's startup due to violent vibrations. For larger pumps, consider increasing the number of braces.

[0023] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. All equivalent changes and modifications made within the scope of the present invention and the contents of the specification are within the scope covered by the present invention.
