Abstract
Description
Technical Field
[0001] The invention relates to the technical field of gangway load testing, in particular to a device for gangway load testing. Background Art
[0002] The original ship repair gangway load test used sandbags as the test load, with each bag weighing 15kg. According to the statistics of the past two years, the proportion of gangways with test loads within 2T is 88.21%. Therefore, the test load is calculated as 2T, and 134 bags are required. The demand for sandbags for the gangway load test is relatively large. Before the gangway load test, a large number of sandbags need to be prepared according to the load requirements. Before the test, the sandbags need to be filled with sand and weighed. Before the test, all the sandbags for the test need to be loaded into a special sandbag bucket, and the sandbag handling personnel stand in the bucket at the same time, generally requiring 3 to 5 people. During the test, the sandbag handling personnel will carry the sandbags to the steps of the gangway, and after the test, the sandbags will be moved back to the sandbag bucket. During the test, a gantry crane is required to cooperate with the lifting of the sandbag bucket. Before the gangway load test, the filling and weighing of a large number of sandbags not only requires the cooperation of multiple people, but also consumes a lot of manpower and time. In addition, each bag of sandbags has a certain weight error. Once it encounters rainy weather, the weight of the sandbags will increase due to water immersion. Therefore, the total weight of the test inevitably has a cumulative error and cannot be effectively controlled. The above factors directly affect the quality of the test. During the test, although the transporters wear safety belts, there are still major safety hazards. The existing gangway load test is time-consuming and laborious. At the same time, repeated handling can easily cause the sandbags to be damaged. During the test, the gantry crane cooperates with the sandbag bucket to lift the sandbag bucket. During the lifting and handling process, due to the instability of the sandbag bucket, it is very easy to cause a metal hard collision between the sandbag bucket and the gangway, resulting in damage to the gangway. The test time for each gangway ladder is about 50 minutes. The original ship repair gangway ladder load test has major drawbacks and can no longer meet the actual needs of the annual ship repair gangway ladder load test for large volume, load flexibility, safety and reliability.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0018] Embodiment 1 See also Figure 1-Figure 6The present invention provides a technical solution: a device for a gangway load test, comprising a tooling body 1 and a counterweight 2. A connecting crossbeam 3 is fixedly installed at the bottom of the tooling body 1. A hanging hole 4 is opened on the connecting crossbeam 3. A plurality of hanging holes 4 are provided and are evenly spaced on the connecting crossbeam 3. A connecting rope 9 is tied to the outer wall of the counterweight 2. A U-shaped connecting piece 8 is fixedly connected to the top of the connecting rope 9. The U-shaped connecting piece 8 is connected to the hanging hole 4 by bolts. There are three connecting ropes 9 tied to the counterweight 2. A lifting lug 11 is fixedly installed on the top of the tooling body 1. The tooling body 1 is used to install the connecting beam 3, and the top of the connecting rope 9 is connected to the connecting beam 3 through the hanging hole 4 and the U-shaped connecting piece 8, and then the counterweight 2 is connected to the connecting beam 3. The crane lifts the tooling body 1 through the lifting lug 11 on the tooling body 1, and then lifts the counterweight 2 to achieve the transportation of the counterweight 2. By carrying the counterweight 2 to the gangway for load testing, no manual transportation is required, which ensures the safety of personnel. Because multiple counterweights 2 are directly hoisted to the gangway, the work efficiency is higher than that of manual transportation; The left and right ends of the tooling body 1 are rotatably provided with extension tooling 7 through a rotating component 12, and a connecting beam 3 is fixedly installed at the bottom of the extension tooling 7. The left and right two extension toolings 7 are provided to extend the length of the tooling body 1, so that the length of the three-section connecting beam 3 is consistent with the length of the gangway ladder, ensuring that the suspended counterweight 2 can match the number of sections of the gangway ladder; The counterweight 2 includes a soft bag body 201, the interior of the soft bag body 201 is filled with sand, and the outer wall of the soft bag body 201 is connected to an inlet and outlet pipe 202, and the soft bag body 201 is used as the outer shell of the counterweight 2, so that the connecting rope 9 is conveniently tied to the counterweight 2, and the sand is filled into the soft bag body 201 through the inlet and outlet pipe 202. Because the internal space of the soft bag body 201 is closed, compared with a sandbag, it can prevent rainwater from soaking the sand; The rotating component 12 includes a fixed plate 1201 and a rotating plate 1202. The fixed plate 1201 is fixedly mounted on the end of the extended tooling 7, and the rotating plate 1202 is fixedly mounted on the end of the tooling body 1. The fixed plate 1201 and the rotating plate 1202 are rotatably connected by a pin shaft. The fixed plate 1201 and the rotating plate 1202 are provided with threaded holes. The fixed plate 1201 and the rotating plate 1202 are fixedly connected by bolts. The extended tooling 7 and the tooling body 1 are connected by the relatively rotatable fixed plate 1201 and the rotating plate 1202, so that the extended tooling 7 can be folded during transportation to reduce the occupied length, thereby reducing the difficulty of transportation. A pull ring 5 is fixedly installed at the bottom of one end of the extension tooling 7 away from the tooling body 1, and a guide rope 6 is tied to the pull ring 5. The two ends of the guide rope 6 are respectively located in the front and rear directions of the extension tooling 7. The pull ring 5 is provided to fix the middle part of the guide rope 6 with the end of the extension tooling 7. Then, during hoisting, the extension tooling 7 can be guided by pulling the guide rope 6. On the one hand, the counterweight 2 can be better hoisted onto the gangway, and on the other hand, the extension tooling 7 can be prevented from colliding with the hull. The length of the tooling body 1 is 10m, and the length of the extended tooling 7 is 3m. The spacing of the hanging holes 4 is 100mm. The spacing of the three hanging holes 4 matches the 300mm step spacing of the gangway, thereby ensuring that one counterweight 2 can be placed just on a section of the gangway; An anti-collision pad 10 is fixedly installed on the front of the tooling body 1. Two anti-collision pads 10 are provided, and are respectively close to the left and right ends of the tooling body 1. The distance between the center of the anti-collision pad 10 and the end of the tooling body 1 is 3m. When the extended tooling 7 is rotated for folding, the end of the extended tooling 7 will contact the anti-collision pad 10 instead of the tooling body 1, avoiding direct collision between the rigid tooling body 1 and the extended tooling 7. An avoidance groove 13 is provided on the top of the connecting crossbeam 3, and the avoidance groove 13 is directly opposite to the rotating component 12, and the avoidance groove 13 is located at the edge of the connecting crossbeam 3 on the tooling body 1, and the avoidance groove 13 is provided to avoid the rotating component 12. Because the avoidance groove 13 is located at the edge of the connecting crossbeam 3 on the tooling body 1, when the fixed plate 1201 and the rotating plate 1202 rotate relatively, the fixed plate 1201 and the rotating plate 1202 will not collide with the inner wall of the avoidance groove 13; Gaps are provided between the counterweights 2 to avoid interference between adjacent counterweights 2. The connecting rope 9 tied to the counterweight 2 is staggered with the feed inlet and outlet pipe 202 to ensure a firm connection between the connecting rope 9 and the counterweight 2 and to avoid the feed inlet and outlet pipe 202 being strangled by the connecting rope 9.
[0019] Working principle: When in use, first place the gangway ladder horizontally, then use bolts to connect the hanging hole 4 and the U-shaped connecting piece 8, connect the hook on the crane with the lifting ear 11, lift the tooling body 1 through the crane, and then drive the connecting beam 3 to rise, lift the counterweight 2, and then lift the counterweight 2 onto the gangway ladder. When lifting, align multiple counterweights 2 with each section of the gangway ladder, and after the connecting rope 9 is loosened, perform a load test. In the process of lifting the counterweight 2, pull the pull ring 5 by pulling the guide rope 6, and then pull the extension tooling 7 to guide the extension tooling 7 to ensure that the counterweight 2 can fall on the gangway ladder. After the load test is completed, the counterweight 2 can be lifted off the gangway ladder.

The tooling body 1 is used to install the connecting beam 3, and the top of the connecting rope 9 is connected to the connecting beam 3 through the hanging hole 4 and the U-shaped connecting piece 8, and then the counterweight 2 is connected to the connecting beam 3. The crane lifts the tooling body 1 through the lifting lug 11 on the tooling body 1, and then lifts the counterweight 2 to achieve the transportation of the counterweight 2. By carrying the counterweight 2 to the gangway for load testing, no manual transportation is required, which ensures the safety of personnel.

Because the internal space of the soft bag body 201 is closed, compared with a sandbag, it can prevent rainwater from soaking the sand; The rotating component 12 includes a fixed plate 1201 and a rotating plate 1202. The fixed plate 1201 is fixedly mounted on the end of the extended tooling 7, and the rotating plate 1202 is fixedly mounted on the end of the tooling body 1. The fixed plate 1201 and the rotating plate 1202 are rotatably connected by a pin shaft. The fixed plate 1201 and the rotating plate 1202 are provided with threaded holes. The fixed plate 1201 and the rotating plate 1202 are fixedly connected by bolts. The extended tooling 7 and the tooling body 1 are connected by the relatively rotatable fixed plate 1201 and the rotating plate 1202, so that the extended tooling 7 can be folded during transportation to reduce the occupied length, thereby reducing the difficulty of transportation. A pull ring 5 is fixedly installed at the bottom of one end of the extension tooling 7 away from the tooling body 1, and a guide rope 6 is tied to the pull ring 5. The two ends of the guide rope 6 are respectively located in the front and rear directions of the extension tooling 7. The pull ring 5 is provided to fix the middle part of the guide rope 6 with the end of the extension tooling 7. Then, during hoisting, the extension tooling 7 can be guided by pulling the guide rope 6. On the one hand, the counterweight 2 can be better hoisted onto the gangway, and on the other hand, the extension tooling 7 can be prevented from colliding with the hull. The length of the tooling body 1 is 10m, and the length of the extended tooling 7 is 3m. The spacing of the hanging holes 4 is 100mm. The spacing of the three hanging holes 4 matches the 300mm step spacing of the gangway, thereby ensuring that one counterweight 2 can be placed just on a section of the gangway; An anti-collision pad 10 is fixedly installed on the front of the tooling body 1. Two anti-collision pads 10 are provided, and are respectively close to the left and right ends of the tooling body 1. The distance between the center of the anti-collision pad 10 and the end of the tooling body 1 is 3m. When the extended tooling 7 is rotated for folding, the end of the extended tooling 7 will contact the anti-collision pad 10 instead of the tooling body 1, avoiding direct collision between the rigid tooling body 1 and the extended tooling 7. An avoidance groove 13 is provided on the top of the connecting crossbeam 3, and the avoidance groove 13 is directly opposite to the rotating component 12, and the avoidance groove 13 is located at the edge of the connecting crossbeam 3 on the tooling body 1, and the avoidance groove 13 is provided to avoid the rotating component 12.
