Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and more specifically to an adjustable testing device. Background Technology

[0002] When the mother ship is sailing, the release hook at the stern of the free-fall lifeboat is connected to the mooring chain on its frame. When the crew hears the boarding command, all crew members board the lifeboat and fasten their seat belts. The helmsman pulls the release handle, the lifeboat release hook is opened, the release hook is disengaged from the mooring chain, and the lifeboat falls freely into the water under the action of gravity. In order to improve the safety and driving comfort of the lifeboat, it is necessary to simulate and measure the attitude and impact force of the free-fall lifeboat when it enters the water.

[0003] Currently, most testing devices have fixed height and angle. These devices can only simulate and measure the attitude and impact force of lifeboats entering the water at the existing height and angle. When the mother ship is sailing in bad sea conditions, it may experience adverse conditions such as roll, trim, and combined trim. When launching lifeboats in such bad sea conditions, existing testing devices cannot simulate and measure the attitude and impact force of lifeboats entering the water.

[0004] Secondly, most testing devices are designed specifically for a certain product, and their slide length and slide spacing are not adjustable, which cannot meet the needs of different models of the same type of product. The testing device is not reusable, and when developing new products of the same type, the testing platform needs to be redesigned, which greatly increases the cost. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable testing device that can adjust the landing height and angle of a free-falling lifeboat to simulate the landing state of the lifeboat under different sea conditions; and can also adjust the slide length and slide spacing to adapt to the testing requirements of different products under different sea conditions, thus saving investment costs.

[0006] The invention includes a frame with a lifting platform connected inside. Guide pulleys are provided on the frame, and steel wire ropes pass through the guide pulleys. One end of the steel wire rope is connected to the lifting platform, and the other end is connected to an electric winch. The lifting platform includes a bracket and a storage platform fixed thereto. Rolling wheels are provided on both sides of the bracket, and the rolling wheels roll up and down within tracks on the left and right sides of the frame. The storage platform includes a boat frame, a first support beam, a second support beam, and a base. The lower part of the boat frame is fixed to the first support beam, the lower part of the first support beam is movably connected to the second support beam, and the lower part of the second support beam is movably connected to the base. The boat frame is provided with a slide length adjustment mechanism and a roller assembly for adjusting the slide width. A lateral angle adjustment mechanism is provided between the first and second support beams, and a longitudinal angle adjustment mechanism is provided between the second support beam and the base.

[0007] Preferably, the lateral angle adjustment mechanism includes an arc-shaped plate, the upper end of which is movably connected to the side of the first support beam, and the lower end of which is movably connected to the side of the second support beam.

[0008] Preferably, the longitudinal angle adjustment mechanism includes an arc-shaped plate II, the upper end of which is movably connected to the front side of the second support beam, and the lower end of which is movably connected to the front side of the base.

[0009] Preferably, the slide length adjustment mechanism includes an adjustment rod, one end of which is connected to the release hook of the lifeboat, and the other end is connected to a pull rope; the adjustment rod is provided with a plurality of adjustment holes at intervals, and the adjustment holes are connected to the lifeboat frame by fasteners.

[0010] Preferably, the roller assembly is arranged on the left and right sides of the boat frame. The roller assembly includes a roller shaft and a roller. The roller is movably connected to the end of the roller shaft. A bushing is also fitted on the roller shaft. The bushing is fixed to the boat frame. The roller shaft and the bushing are connected by fastening bolts.

[0011] Preferably, there are several roller assemblies, which are spaced apart along the length of the boat frame.

[0012] Preferably, the bushing is also provided with an oil cup, and the oil cavity of the oil cup is connected to the surface of the roller shaft.

[0013] In summary, the present invention has the following beneficial effects:

[0014] 1. The electric winch enables the lifting platform to rise and fall, which can simulate the attitude and impact of a lifeboat being lowered into the water at different heights. The adjustable test device has a simple structure and is easy to operate. The power source of the whole system is the electric winch, which has a low failure rate.

[0015] 2. By adjusting the lateral angle adjustment mechanism and the longitudinal angle adjustment mechanism, the attitude and impact force of lifeboats being lowered into the water when the mother ship is listing, listing, or listing in combination can be simulated, which can meet a variety of test scenarios, making the test range wider, the simulation more realistic, and the test data more accurate.

[0016] 3. By adjusting the slide length adjustment mechanism and roller assembly, the descent distance and slide spacing of the lifeboat can be adjusted to meet the needs of multiple models of lifeboats of the same type, greatly reducing cost investment, with a wide range of applications and strong scalability, laying a good foundation for the diversification of future product testing.

[0025] The invention will now be further described with reference to the accompanying drawings.

[0026] The orientations mentioned in this specification are based on the orientation of the adjustable testing device of the present invention during normal operation, and do not limit its orientation during storage and transportation. They only represent relative positional relationships and do not represent absolute positional relationships.

[0027] like Figures 1 to 8 As shown, an adjustable testing device includes a frame 1, a lifting platform 5 connected inside the frame 1, a guide pulley 2 on the frame 1, a steel wire rope 3 passing through the guide pulley 2, one end of the steel wire rope 3 connected to an electric winch 4, and the other end connected to the lifting platform 5; the lifting platform 5 includes a bracket 7 and a storage platform 9 fixed thereto, and four rollers 8 are provided on both sides of the bracket 7, distributed on the left and right sides of the bracket 7. The rollers 8 roll up and down in the tracks on the left and right sides of the frame of the frame 1, thereby driving the lifting platform 5 to move up and down, realizing the adjustment of the height of the testing device, used to simulate the water landing state of the lifeboat 6 at different heights.

[0028] The storage platform 9 includes a boat frame 91, a first support beam 92, a second support beam 93, and a base 94. The boat frame 91 is used to store the lifeboat 6. The boat frame 91 is equipped with a slide length adjustment mechanism 98 and a roller assembly 97 for adjusting the slide width. The first support beam 92 and the second support beam 93 are both rectangular frame structures. The first support beam 92 is fixed to the bottom of the boat frame 91, and the second support beam 93 is stacked below the first support beam 92. The left side beam of the first support beam 92 is movably connected to the left side beam of the second support beam 93 by fasteners, and the right side beam of the first support beam 92 is movably connected to the right side beam of the second support beam 93 by a lateral angle adjustment mechanism 96. The front beam of the second support beam 93 is movably connected to the front side of the base 94 by a longitudinal angle adjustment mechanism 95, and the rear beam of the second support beam 93 is movably connected to the rear side of the base 94 by fasteners.

[0029] The lateral angle adjustment mechanism 96 includes two arc-shaped plates, distributed at the front and rear ends of the right side beam of the first support beam 92. Each arc-shaped plate has at least three through holes (top, middle, and bottom). Ear plates are provided on the right side beams of the first support beam 92 and the second support beam 93 at positions corresponding to the arc-shaped plates. The upper end of the arc-shaped plate is movably connected to the ear plate of the right side beam of the first support beam 92 via fasteners, and the lower end of the arc-shaped plate is movably connected to the ear plate of the second support beam 93 via fasteners. When it is necessary to adjust the lateral tilt angle of the boat frame 91... First, loosen the fasteners at the connection between the left side beam of the first support beam 92 and the second support beam 93. Then, loosen the fasteners at the connection between the arc plate 1 and the second support beam 93, allowing the boat frame 91 to rotate around the fasteners on the left side and adjust its lateral tilt angle to the required position. Locate the corresponding through hole on the arc plate 1 at this position, align this through hole with the ear plate hole on the second support beam 93, and tighten all fasteners. This completes the adjustment of the lateral angle of the boat frame 91, which can be used to simulate the landing state of the lifeboat 6 at different angles in the lateral direction.

[0030] The longitudinal angle adjustment mechanism 95 includes two arc-shaped plates, distributed at the left and right ends of the front beam of the second support beam 93. Each arc-shaped plate has at least three through holes (upper, middle, and lower). Ear plates are provided on the front beam of the second support beam 93 and the base 94 at positions corresponding to the arc-shaped plates. The upper end of the arc-shaped plate is movably connected to the ear plate of the front beam of the second support beam 93 via fasteners, and the lower end of the arc-shaped plate is movably connected to the ear plate of the base 94 via fasteners. When adjusting the longitudinal tilt angle of the boat frame 91, first loosen the fasteners at the connection between the rear beam of the second support beam 93 and the base 94, then loosen the fasteners at the connection between the arc-shaped plate and the base 94, rotate the boat frame 91 to adjust its longitudinal tilt angle to the required position, locate the through hole on the arc-shaped plate at this position, align this through hole with the ear plate hole on the base 94, and tighten all fasteners. This completes the adjustment of the longitudinal angle of the boat frame 91, which can be used to simulate the landing state of the lifeboat 6 at different angles in the longitudinal direction.

[0031] Furthermore, when the lateral angle adjustment mechanism 96 and the longitudinal angle adjustment mechanism 95 are adjusted simultaneously, the state of the lifeboat 6 falling into the water when the mother ship is in a compound tilt state under severe sea conditions can be simulated. The simultaneous adjustment of the lateral angle adjustment mechanism 96 and the longitudinal angle adjustment mechanism 95 can be combined to produce a variety of angle changes to adapt to the test requirements under different sea conditions.

[0032] The slide length adjustment mechanism 98 includes an adjustment rod 981. One end of the adjustment rod 981 is connected to the release hook of the lifeboat 6, and the other end is connected to a pull rope 982. A pull ring 983 is connected to the pull rope 982. Multiple adjustment holes are spaced apart on the adjustment rod 981. The adjustment holes are connected to the boat frame 91 by fasteners. When it is necessary to adjust the slide length, loosen the fasteners, pull the pull ring 983 to make the adjustment rod 981 in the appropriate position, align the adjustment holes with the ear plate holes on the boat frame 91, and tighten the fasteners to complete the adjustment of the slide length.

[0033] Several roller assemblies 97 are provided, arranged on the left and right sides of the boat frame 91, spaced apart along the length of the boat frame 91. Each roller assembly 97 includes a roller shaft 971 and rollers 974. Rollers 974 are movably connected to the end of the roller shaft 971, with a clearance fit between them to ensure free rotation of the rollers 974. The use of rollers 974 reduces friction during the lowering and launching of the lifeboat 6. A bushing 972 is also fitted onto the roller shaft 971, and the bushing 972 is fixed to the boat frame 91. The roller shaft 971 can... The roller shaft 971 moves along its length within the bushing 972, thereby adjusting the distance between the left and right rollers 974 on the boat frame 91. The roller shaft 971 and the bushing 972 are connected by fastening bolts 975. The bushing 972 is also equipped with an oil cup 973, the oil cavity of which is connected to the surface of the roller shaft 971. After the position of the roller shaft 971 is adjusted, the roller shaft 971 is firmly fixed with fastening bolts 975, and grease is injected through the oil cup 973 to prevent corrosion of the roller shaft 971 and the bushing 972.

[0034] By adjusting the slide length adjustment mechanism 98 and the roller assembly 97, the sliding distance and slide spacing of the lifeboat 6 can be adjusted, which can meet the needs of multiple models of lifeboat 6 products of the same type, greatly reduce the cost investment, have a wide range of applications, and strong scalability, laying a good foundation for the diversification of future product testing.
