Description
Technical Field
[0001] The invention relates to the field of shipbuilding, and in particular to a base reinforcement structure for a cargo oil pump. Background Art
[0002] The cargo oil pump is a special machine on the cargo oil tanker. The loading and unloading of cargo oil is mainly completed by it, so it is as important as the cargo lifting machine on the dry cargo ship. Due to the different sizes of cargo oil tankers, different types of oil loaded, and different specific conditions of each type of ship, the requirements for cargo oil pumps are also different.
[0003] After the current cargo oil pump is installed, you need to use a reinforcing structure to fix and strengthen the base between the base and the hull. The existing base reinforcement structure.
[0004] Since the hull design and manufacturing process is completed in stages, the existing cargo oil pump base reinforcement structure is pre-designed before the cargo oil pump is installed and pre-installed on the back of the floor of the cabin where the cargo oil pump is located during the hull construction process. This can not only reduce the ship's occupation of the internal space of the cabin and facilitate the maintenance and repair of the cargo oil pump, but also improve the efficiency of subsequent cargo oil pump installation. When installing the subsequent cargo oil pump, the base can be directly erected on top of the reinforcement structure and installed.
[0005] However, during the construction of cargo oil tankers, the design drawings and specific parameter information of the cargo oil pump may be changed according to different situations. This results in the installation position of the base of the cargo oil pump during actual installation not corresponding to the position of the original pre-installed reinforcement structure, which in turn makes the base directly installed on the cabin floor unstable and causes the cargo oil pump to generate great vibration when in use. Summary of the invention
[0006] The technical problem to be solved by the present invention is to provide a base reinforcement structure for a cargo oil pump which is directly installed inside a cabin and can stabilize the cargo oil pump base and reduce vibration when the cargo oil pump is working.

[0027] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.
[0028] See attached Figures 1 to 6 , a base reinforcement structure for a cargo oil pump of the present invention comprises a base and a support member;
[0029] The base is fixedly connected to the side wall of the cabin through a support member, and the base includes a top plate 1 and two mutually parallel support plates 2 fixedly connected to the bottom of the top plate 1, and the two support plates 2 are fixedly connected by a side plate 3;
[0030] The support member includes a panel 4 and a web 5. The panel 4 is an isosceles trapezoid. There are two webs 5. The two webs 5 are fixedly connected to two symmetrical oblique sides of the panel 4. An arc-shaped first notch 51 is provided at the bottom of the web 5. A slot 11 corresponding to the web 5 is provided on the lower surface of the top plate 1. The top end of the web 5 is clamped in the slot 11.
[0031] The panel 4 has a protrusion 41 on one edge close to the carrier plate 2 , and the carrier plate 2 has a groove 21 on its surface corresponding to the protrusion 41 . The protrusion 41 is embedded in the groove 21 , and the web 5 has a fixed connection with the carrier plate 2 on one edge close to the base.
[0032] The working principle of the present invention is as follows: when installing the support member, first align the top end of the web 5 with the slot 11 on the lower surface of the top plate 1, and push the web 5 toward the base, then align the raised portion 41 of the panel 4 with the groove 21 on the surface of the carrier plate 2, wherein the raised portion 41 and the groove 21 are transitionally matched, so it is necessary to use a hammer to gently knock the carrier plate 2 toward the direction of the panel 4, and when the raised portion 41 is successfully embedded in the groove 21, the support member and the base can be relatively fixed, and at this time, the support member is fixedly connected to the cabin side wall by welding or bolting, and the base is also fixedly connected to the cabin floor by welding or bolting.
[0033] After the reinforcement structure is installed, the bottom of the support member does not contact the cabin floor. Since the base is connected to the cabin side wall as a whole through the support member, the resonant frequency of the base is changed and the rigidity is increased, thereby achieving the effect of vibration reduction. At the same time, since the ship is subjected to large vibrations from waves when sailing on the sea, and the part connected by bolts between the cargo oil pump and the base is relatively fragile, in order to avoid the horizontal impact caused by the vibration of the hull causing irreparable damage to the connection between the cargo oil pump and the base, an arc-shaped first notch 51 is provided at the bottom of the web 5 of the support member, so that when the hull is subjected to a large horizontal impact, the part of the first notch 51 on the web 5 can be more easily compressed and deformed, thereby absorbing the energy generated by the impact, and avoiding damage to the connection between the cargo oil pump and the base.
[0034] Since the panel 4 is an isosceles trapezoid, the webs 5 symmetrically connected to both sides of the panel 4 are not parallel, but form a structure similar to a triangular support, thereby further improving the connection stability between the base and the cabin side wall.
[0035] From the above description, it can be seen that the beneficial effects of the present invention are: the support member can be directly installed inside the cabin, and connect the base with the side wall of the cabin, so as to change the working frequency of the base and improve its rigidity, and reduce the vibration generated when the cargo oil pump is working; when the hull is subjected to a large horizontal impact, the part of the first notch on the web can be more easily compressed and deformed, thereby absorbing the energy generated by the impact, and avoiding damage to the connection between the cargo oil pump and the base; the trapezoidal panel can make the two webs form a stable structure of triangular support, thereby improving the connection stability between the base and the side wall of the cabin.
[0036] Furthermore, a hook 52 is provided on one side of the web 5 close to the base, and a slot 22 corresponding to the hook 52 is provided on the support plate 2 of the base, and the hook 52 is engaged in the slot 22 .
[0037] It can be seen from the above description that the web plate and the carrier plate are reinforcedly connected by hooks, so that no additional welding is required between the web plate and the carrier plate, thereby improving installation efficiency.
[0038] Furthermore, the top end of the web 5 rises linearly from the side close to the cabin side wall to the side close to the base, and the hook 52 includes a connecting rod 521, an upper hook 522 and a lower hook 523. The height of the bayonet 22 is equal to the length of the upper hook 522. One end of the connecting rod 521 is fixedly connected to the web 5, and the other end is fixedly connected to the upper hook 522. The lower hook 523 is hinged to the bottom end of the upper hook 522. A limit block 524 is provided on the side of the upper hook 522 close to the base for limiting the unidirectional rotation of the lower hook 523.
[0039] From the above description, it can be seen that since the height of the bayonet is equal to the length of the upper hook, the hook cannot be directly installed into the bayonet, and the support can only be slightly tilted so that the top of the web rotates from the tilted state to the horizontal state. At this time, the support is pushed toward the base so that the upper hook extends into the bayonet. When the raised portion on the panel is embedded in the groove, the support is rotated to its original position. During the rotation, the lower groove is blocked by the edge of the bayonet, thereby rotating clockwise relative to the upper hook and extending into the bayonet. When the lower hook is fully extended into the bayonet, the lower hook returns to its original position under the action of its own weight, and due to the limitation of the limit block, the lower hook cannot rotate counterclockwise. At this time, the hook is fully inserted into the bayonet, ensuring a fixed connection between the support and the base and preventing detachment.
[0040] Furthermore, a second notch 53 is provided at the top of the web 5 near the corner of the base.
[0041] From the above description, it can be seen that since the top of the web is inclined, the stress at the corner where the top of the web is clamped in the groove is relatively large. Providing a second notch at the corner can avoid damage caused by excessive stress at the corner.
[0042] Furthermore, third notches 42 are provided at four corners of the panel 4 .
[0043] Furthermore, a first through hole 43 is opened in the middle of the panel 4 .
[0044] It can be seen from the above description that the first through hole in the middle of the panel can facilitate the staff to insert the tool under the cargo oil pump through the first through hole and inspect the cargo oil pump.
[0045] Furthermore, a second through hole 12 is opened in the middle of the top plate 1 , and a third through hole 23 is opened in the middle of the support plate 2 .
[0046] It can be seen from the above description that the second through hole of the top plate and the third through hole of the support plate can facilitate the staff to insert the tool into the bottom of the cargo oil pump through the second through hole and the third through hole and inspect the cargo oil pump.
[0047] Furthermore, the support plate 2 is in a trapezoidal shape.
[0048] It can be seen from the above description that the trapezoidal shape of the support plate can improve the stability of the base.
