Description

Technical Field

[0001] The invention relates to the technical field of gangway ladder load testing, in particular to a novel gangway ladder load testing device. Background Art

[0002] Gangway refers to a movable ladder installed on both sides of a ship for passengers to get on and off the ship. It is made of wood or metal and consists of upper and lower platforms, ladder frames, steps, handrails and hanging ladder devices. It is hoisted when the ship is sailing, folded and stored on the deck, and lowered and hung on the side when in use. Gangway devices are generally used in passenger ships and other large and medium-sized ships. When a ship is undergoing repair inspection, it is usually necessary to complete a load test on the gangway.

[0003] At present, sandbags are usually used as test loads for load tests on gangways, which have the following shortcomings in actual use: 1. The existing gangway load test uses sandbags as the test load, each bag is 15kg. According to the statistics of the past two years, the proportion of gangway with test load within 2T is 88.21%. Therefore, if the test load is calculated as 2T, 134 sandbags are needed, and the demand for sandbags for gangway load test is relatively large; 2. Before the gangway load test, a large number of sand bags need to be prepared according to the load requirements. The filling and weighing of sand bags not only requires the cooperation of multiple people, but also consumes a lot of manpower and time. In addition, each sand bag has a certain weight error. Once it encounters rainy weather, the weight of the sand bag will increase due to water immersion. Therefore, the total test weight inevitably has a cumulative error and cannot be effectively controlled. The above factors directly affect the test quality; 3. Before the gangway load test, all the sandbags for the test shall be loaded into a special sandbag bucket, and the sandbag handling personnel shall stand in the bucket at the same time, generally 3 to 5 persons are required. Although the handling personnel wear safety belts, there are still great safety hazards; 4. During the gangway load test, the sandbags are carried to the steps of the gangway by the sandbag carriers. After the test, the sandbags are moved back into the sandbag bucket. The test is time-consuming and laborious. At the same time, repeated handling can easily cause the sandbags to be damaged. During the test, a gantry crane is used to lift the sandbag bucket. During the lifting and handling process, the sandbag bucket is unstable, which can easily cause a hard metal collision between the sandbag bucket and the gangway ladder, thereby causing damage to the gangway ladder. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a novel gangway load testing device to solve the problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a new type of gangway load testing device, comprising a plurality of hanging beams, a plurality of connecting beams and a plurality of water bags, the connecting beam being arranged between two adjacent hanging beams, a plurality of hooks being fixedly connected to the bottom outer surface of the hanging beam, a plurality of connecting ropes being fixedly connected to the left and right outer surfaces of the plurality of water bags, a plurality of lifting rings being fixedly connected to the top outer surfaces of the two corresponding connecting ropes on the left and right sides, two lifting ears being fixedly connected to the top outer surface of the hanging beam, a plurality of lifting ears being connected by steel ropes, a water inlet joint being fixedly connected to the left outer surface of the water bag, and a drainage joint being fixedly connected to the right outer surface of the water bag.

[0007] As a further illustration of the present invention, a flow meter is installed outside the water supply pipe.

[0008] As a further description of the present invention, a first valve is installed on the outside of the water supply pipe, and a second valve is installed on the outside of each of the plurality of branch pipes.

[0009] As a further explanation of the present invention, the relative outer surfaces of two adjacent suspension beams are fixedly connected with a rotating seat, the outer surface of the rotating seat is rotatably connected with a damping shaft, and the connecting beam is fixedly sleeved on the outer surface of the damping shaft between the two corresponding rotating seats.

[0010] As a further explanation of the present invention, the outer surfaces of the rotating seat and the connecting beam are both provided with a first plug hole, a pin shaft is movably inserted into the first plug holes corresponding to the rotating seat and the connecting beam, and a cotter pin is movably inserted into the axial hole of the pin shaft.

[0011] As a further description of the present invention, the connecting beam is provided with second insertion holes on both upper and lower sides of the first insertion hole.

[0012] As a further explanation of the present invention, a one-way valve is installed inside the water inlet joint, and the flow direction of the one-way valve is from the inside of the water inlet joint to the inside of the water bag. A sealing cover is installed on the outer surface of the drainage joint.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In a novel gangway load test device provided by the present invention, water is added to the water bag to increase the weight in the water bag, and then the water bag is lifted by the lifting beam, and the water bag is lifted to the gangway that needs to be tested, thereby replacing the traditional sandbag load mode, liberating labor, and improving the efficiency of load testing. The test time of each gangway ladder is reduced by 0.5 hours, and the cost of manual filling and transportation of sandbags is saved. The number of test partners is reduced by 3 people, and the test efficiency of each gangway ladder is improved by more than 30%, saving the cost of about 3,000 yuan. At the same time, during the test, the test personnel do not need to work on the side of the ship or at high altitude, eliminating the safety hazards of the test. The strength of the device exceeds the test strength requirement, and the safety reaches 100%.

[0014] 2. In a novel gangway ladder load test device provided by the present invention, water bags are used instead of sand bags, and there is no need to put the sand bags into a special sand bag bucket, thereby avoiding the metal hard collision between the sand bag bucket and the gangway ladder during lifting and transportation due to the instability of the sand bag bucket, thereby avoiding damage to the gangway ladder.

[0015] 3. In a novel gangway load test device provided by the present invention, when the hanging beam needs to be folded and stored when not in use, the cotter pin and the pin shaft are removed to allow the rotating seat and the connecting beam to rotate, and the pin shaft is inserted into the second insertion hole, and then the cotter pin is inserted into the shaft hole of the pin shaft to limit the rotating seat and the connecting beam, so that multiple hanging beams and connecting beams can be stored in a "2" shape, thereby reducing the space occupied by the hanging beam when not in use.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1: Please refer to Figure 1-Figure 5 The present invention provides a technical solution: a novel gangway load test device, comprising a plurality of hanging beams 1, a plurality of connecting beams 2 and a plurality of water bags 4, wherein the connecting beam 2 is arranged between two adjacent hanging beams 1, a plurality of hooks 3 are fixedly connected to the bottom outer surface of the hanging beam 1, a plurality of connecting ropes 5 are fixedly connected to the left and right outer surfaces of the plurality of water bags 4, a plurality of connecting ropes 5 are fixedly connected to the top outer surfaces of the two corresponding connecting ropes 5 on the left and right sides, a lifting ring 6 is fixedly connected to the top outer surface of the hanging beam 1, and the plurality of lifting ears 9 are connected by steel ropes, a water inlet joint 7 is fixedly connected to the left outer surface of the water bag 4, and a drainage joint 8 is fixedly connected to the right outer surface of the water bag 4, Specifically, the lifting ring 6 on the connecting rope 5 of the water bag 4 is hung on the hook 3, and a plurality of lifting ears 9 are connected by a steel rope, and then the steel rope connected to the lifting ear 9 is connected by the hook of the crane, and the lifting beam 1 is lifted, and the water bag 4 is lifted onto the gangway for a load test, and the load test is tested by a precise testing device. The traditional sand belt load mode takes about fifty minutes to perform a load test on each gangway, while it only takes twenty minutes to perform a load test using the load testing device. The gangway test time is reduced by 0.5 hours, which improves the test efficiency. The water bag 4 is provided instead of the sand bag to avoid metal hard collision between the gangway and the test device.

[0020] In this embodiment, a water supply pipe 16 is also included. The water supply pipe 16 is fixedly connected to the output end of the external water pump. The other end of the water supply pipe 16 is fixedly connected to a water divider 17. The water dividing end of the water divider 17 is fixedly connected to a branch pipe 18. Specifically, the supplied water flow is evenly diverted by the water divider 17, thereby improving the uniformity of water filling in multiple water bags 4.

[0021] In this embodiment, a flow meter 19 is installed on the outside of the water supply pipe 16. Specifically, the amount of water supplied is recorded by the flow meter 19, so as to accurately supply water, ensure the weight of the water bag 4, and ensure the accuracy of the load test.

[0022] In this embodiment, a first valve 20 is installed on the outside of the water supply pipe 16, and a second valve 21 is installed on the outside of each of the multiple branch pipes 18. Specifically, the first valve 20 is opened to allow the water in the water supply pipe 16 to enter the water distributor 17. According to the branch pipe 18 that needs water supply, the second valve 21 is opened so that the water distributor 17 divides the water and then enters the water delivery pipe through the branch pipe 18 and finally enters the water bag 4.

[0023] In this embodiment, a one-way valve is installed inside the water inlet joint 7, and the flow direction of the one-way valve is from the inside of the water inlet joint 7 to the inside of the water bag 4. A sealing cover is installed on the outer surface of the drainage joint 8. Specifically, by setting the one-way valve, when the water supply is completed, the water pipe needs to be disconnected from the water inlet joint 7 to avoid water backflow. When the water in the water bag 4 needs to be discharged, the sealing cover is unscrewed to allow the water to be discharged from the drainage joint 8.

[0024] In the specific implementation process, when it is necessary to carry out a load test on the gangway, the branch pipe 18 is connected to the water inlet joint 7 through the water pipe, and the water flow is delivered to the water supply pipe 16 through the external water pump. After the first valve 20 is opened, the water flow enters the water distributor 17 for diversion, and the water flow enters the water pipe through the branch pipe 18 and enters the water bag 4 through the water inlet joint 7. Water flow is injected into the water bag 4, and the amount of injected water flow is displayed by the flow meter 19, so that the water in the water bag 4 reaches the specified appropriate weight, and then the water bag 4 is connected to the rope. The lifting ring 6 on 5 is hung on the hook 3, and multiple lifting ears 9 are connected by steel ropes, and then the lifting hook of the crane is connected to the steel rope connected to the lifting ear 9, the lifting beam 1 is lifted, and the water bag 4 is lifted to the gangway for load test. The load test is tested by precise testing equipment. The traditional sand belt load mode takes about fifty minutes to perform a load test on each gangway, while the load test device only takes twenty minutes to perform a load test. The gangway test time is reduced by 0.5 hours, which improves the test efficiency.

[0025] In summary, a new type of gangway ladder load test device proposed in the present invention replaces the traditional sandbag load mode, liberates labor, improves the efficiency of load testing, reduces the test time of each gangway ladder by 0.5 hours, and saves the cost of manual filling and transportation of sandbags. The number of test partners is reduced by 3 people, and the test efficiency of each gangway ladder is improved by more than 30%, saving the cost of about 3,000 yuan. At the same time, by arranging a water bag 4 instead of a sandbag, the metal hard collision between the gangway ladder and the test device is avoided. During the test, there is no need for the test personnel to work on the side of the ship or at high altitude, eliminating the safety hazards of the test. The strength of the device exceeds the test strength requirement, and the safety reaches 100%.

[0026] Embodiment 2: Please refer to Figure 1-Figure 5The present invention provides a technical solution: the relative outer surfaces of two adjacent suspension beams 1 are fixedly connected with a rotating seat 10, the outer surface of the rotating seat 10 is rotatably connected with a damping shaft 11, and the connecting beam 2 is fixedly sleeved on the outer surface of the damping shaft 11 between the two corresponding rotating seats 10.

[0027] In this embodiment, a first socket 12 is provided on the outer surface of the rotating seat 10 and the connecting beam 2, a pin shaft 13 is movably inserted into the first socket 12 corresponding to the rotating seat 10 and the connecting beam 2, and a cotter pin 14 is movably inserted into the axial hole of the pin shaft 13. Specifically, the pin shaft 13 is inserted into the corresponding positions of the first socket 12 on the rotating seat 10 and the first socket 12 on the connecting beam 2, and then the cotter pin 14 is inserted into the axial hole of the pin shaft 13 to limit the position between the connecting beam 2 and the suspension beam 1.

[0028] In this embodiment, the connecting beam 2 is provided with second holes 15 on the upper and lower sides of the first hole 12. Specifically, when the rotating seat 10 and the connecting beam 2 are rotated to be perpendicular to each other, the first hole 12 on the rotating seat 10 corresponds to the second hole 15, and then the pin shaft 13 is inserted into the first hole 12 and the second hole 15 on the rotating seat 10, and then the cotter pin 14 is inserted into the axial hole of the pin shaft 13 to limit the position between the suspension beam 1 and the connecting beam 2 when they are stored.

[0029] During the specific implementation process, when the suspension beam 1 needs to be folded and stored, the cotter pin 14 is removed and the pin shaft 13 is pulled out so that the rotating seat 10 and the connecting beam 2 can rotate. After the suspension beam 1 and the connecting beam 2 are adjusted to the appropriate position, the pin shaft 13 is inserted into the corresponding second socket 15, and the cotter pin 14 is inserted into the axial hole of the pin shaft 13 to limit the rotating seat 10 and the connecting beam 2, and the multiple suspension beams 1 and the connecting beams 2 are stored in a "2" shape, thereby reducing the space occupied by the suspension beam 1 when not in use.

[0030] Working principle: In actual use of the present invention, when it is necessary to carry out a load test on the gangway, the branch pipe 18 is connected to the water inlet joint 7 through the water pipe, and the water flow is transported to the water supply pipe 16 through the external water pump. After the first valve 20 is opened, the water flow enters the water distributor 17 for diversion, and the water flow enters the water pipe through the branch pipe 18 and enters the water bag 4 through the water inlet joint 7. Water flow is injected into the water bag 4, and the amount of injected water flow is displayed by the flow meter 19, so that the water in the water bag 4 reaches a specified appropriate weight, and then the lifting ring 6 on the connecting rope 5 of the water bag 4 is hung on the hook 3, and a plurality of lifting ears 9 are connected by a steel rope, and then the steel rope connected to the lifting ears 9 is connected by the hook of the crane, and the lifting beam 1 is lifted, and the water bag 4 is lifted onto the gangway. The load test is carried out by using precise detection equipment. The traditional sand belt load mode takes about fifty minutes to carry out load test on each gangway ladder, while the load test device only takes twenty minutes. The gangway ladder test time is reduced by 0.5 hours, which improves the test efficiency. At the same time, it saves the cost of manual filling and transportation of sand bags, and the number of test partners is reduced by 3. The test efficiency of each gangway ladder is improved by more than 30%, saving about 3,000 yuan in costs. At the same time, the water bag 4 is set to replace the sand bag to avoid the metal hard collision between the gangway ladder and the test device. During the test, there is no need for the test personnel to work on the side of the ship or at high altitude, eliminating the safety hazards of the test. The strength of the device exceeds the test strength requirement, and the safety reaches 100%.

[0031] When the suspension beam 1 needs to be folded and stored, remove the cotter pin 14 and pull out the pin shaft 13, so that the rotating seat 10 and the connecting beam 2 can rotate. After adjusting the suspension beam 1 and the connecting beam 2 to the appropriate position, insert the pin shaft 13 into the corresponding second plug hole 15, and insert the cotter pin 14 into the axial hole of the pin shaft 13 to limit the rotating seat 10 and the connecting beam 2, and store the multiple suspension beams 1 and the connecting beams 2 into a "2" shape, thereby reducing the space occupied by the suspension beam 1 when not in use.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
