Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of ship partial load inclination test, and particularly relates to an adjustable test counterweight structure. Background Technique
[0002] The partial load inclination test is to verify the heel angle obtained when the maximum number of crew members (crew limit) of the ship is concentrated on one side under the full load condition. When the ship is conducting the partial load inclination test, it is necessary to use the weight of the maximum number of crew members for testing. The current tests mainly use crew boarding tests or use water-filled buckets and sandbags to simulate the weight for testing. Using crew members for testing has the risk of falling into the water, while using sandbags or other buckets has an unclear weight, and the on-site measurement of the mass cannot achieve a reliable effect. In addition, the mass of the sandbags will increase due to continuous water absorption. Moreover, the center of gravity of the test weights cannot reach the required corresponding height, and the accuracy of the test results will be adversely affected. Therefore, in view of the above problems, it is of great significance to provide an adjustable test counterweight structure according to the utility model. Content of the Utility Model

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0028] In the description of the present utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc. indicating the orientation or positional relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present utility model.
[0029] Please refer to Figures 1-6As shown in the figure, an adjustable test counterweight structure of the utility model includes a base 1. The base 1 is U-shaped, and a vertical rod 2 is fixedly connected to the center of its top. Lifting components are installed on both sides of the base 1. A number of counterweight weights 3 are stacked on the base 1. The counterweight weights 3 are circular, and through holes 4 are provided at their centers. The vertical rod 2 can pass through the through holes 4 on multiple counterweight weights 3 at the same time, so as to stack multiple counterweight weights 3 together. When the base 1 together with multiple counterweight weights 3 is placed on a ship, it can replace personnel boarding the ship to complete the offloading and tilting test of the ship, thus effectively reducing the risk of falling into the water caused by personnel falling into the water during the test or the ship capsizing due to the test not passing. The counterweight weights 3 are standard parts with accurate masses, which can make the test highly reliable. And by adjusting the stacking height of the counterweight weights 3, the center of gravity height of personnel can be simulated, eliminating the moment influence caused by different center of gravity heights and making the test results more accurate;
[0030] The lifting component includes a mounting plate 5. A lifting ring 6 is fixedly connected to one side of the mounting plate 5. The lifting ring 6 is C-shaped. A number of screw rods 7 are fixedly connected to the other side of the mounting plate 5. Nuts 8 that are matched with the screw rods 7 are threadedly connected to the screw rods 7. The hook of an external lifting device can be hooked on the lifting ring 6 so as to lift the counterweight structure for movement and handling.
[0031] Among them, a number of anti-slip pads 9 are provided on the bottom surface of the base 1. The anti-slip pads 9 are strip-shaped and are linearly distributed at equal intervals along the length direction of the base 1. And the surface of each anti-slip pad 9 is engraved with herringbone anti-slip patterns. The anti-slip pads 9 are made of elastic materials such as rubber and are fixed by means of glue. When the base 1 is placed on the ship, the anti-slip patterns on the surfaces of the anti-slip pads 9 can be used to increase the friction between the base 1 and the ship to play an anti-slip role, thereby preventing the counterweight structure from slipping and displacing during the test and affecting the accuracy of the test results.
[0032] Among them, a number of mounting holes 10 are provided on both sides of the base 1. The number of mounting holes 10 is the same as that of the screw rods 7 and their diameters are equal. And the center of each mounting hole 10 corresponds to the center of each screw rod 7 one by one. Each screw rod 7 can be aligned and pass through the corresponding mounting hole 10. At this time, the nuts 8 are threadedly connected to the screw rods 7 and tightened, and the mounting plate 5 together with the entire lifting component can be fixed on the base 1 through the mutual cooperation among the screw rods 7, the mounting holes 10, and the nuts 8. And when the lifting component has been used for a long time, the lifting component can be removed by unscrewing the nuts 8 so as to maintain or replace it.
[0033] Among them, a pair of reinforcing blocks 11 are fixedly connected to the inner walls on both sides of the base 1. The reinforcing blocks 11 are triangular, and their bottoms are fixedly connected to the top of the base 1. The base 1 can be reinforced through the reinforcing blocks 11 so as to improve the structural strength of the base 1 and prevent it from deforming after being stressed for a long time.
[0034] Among them, a buffer sleeve 12 is sleeved on the rod body of the vertical rod 2. The buffer sleeve 12 is made of an elastic material such as silica gel. When the vertical rod 2 passes through the through holes 4 on each counterweight 3, the buffer sleeve 12 can play a role in buffer protection to prevent the vertical rod 2 from directly contacting the hole wall of the through hole 4 and causing collision and wear.
[0035] Among them, a plurality of clamping blocks 13 are fixedly connected to the top of each counterweight 3, and a plurality of clamping grooves 14 are formed on the bottom surface of each counterweight 3. The cross sections of the clamping grooves 14 and the clamping blocks 13 are circular, their numbers are the same, their diameters are equal, and the clamping grooves 14 and the clamping blocks 13 are evenly distributed in an annular shape along the circumferential direction of the counterweight 3. The centers of each clamping groove 14 and each clamping block 13 correspond to each other one by one. When a plurality of counterweights 3 are stacked together, each clamping block 13 can be aligned and inserted into the corresponding clamping groove 14. At this time, the mutual cooperation between the clamping block 13 and the clamping groove 14 can play a role in limiting, so as to improve the stability of the stacked counterweights 3 and prevent them from loosening and shifting.
[0036] Among them, a layer of buffer pad 15 is arranged on the top surface of each clamping block 13. The buffer pad 15 is made of an elastic material such as rubber and is fixed by means such as glue. When a plurality of counterweights 3 are stacked together and each clamping block 13 is inserted into the clamping groove 14, the buffer pad 15 can be padded at the bottom of the clamping groove 14. At this time, the buffer pad 15 can play a role in buffer protection to prevent the counterweights 3 from directly contacting each other and causing collision and wear when stacked together.

[0039] The working principle of the present utility model is:
[0040] When in use, the utility model can hook the lifting hook on the lifting ring 6 through an external lifting device, so as to lift, move and transport the counterweight structure to the ship to be subjected to the offloading inclination test. The counterweight structure can pass through the through holes 4 on multiple counterweight weights 3 simultaneously through the vertical rod 2, so as to stack the multiple counterweight weights 3 together. When the base 1 and the multiple counterweight weights 3 are placed on the ship together, it can replace personnel boarding the ship to complete the offloading inclination test of the ship, thereby effectively reducing the risk of falling into the water caused by personnel falling into the water during the test or the ship capsizing due to the failure of the test. The counterweight weight 3 is a standard part with accurate mass, which can make the test result highly reliable. And by adjusting the stacking height of the counterweight weight 3, the center of gravity height of personnel can be simulated, eliminating the moment influence caused by different center of gravity heights and making the test result more accurate.
