Description

Technical Field

[0001] This utility model is a cabin crane test bench, belonging to the field of cabin crane. Background Technology

[0002] An engine room crane is a lifting device used in the engine room of a ship, primarily for main engine maintenance and other related work. An engine room crane test bench is a device used for performance testing, debugging, and research of engine room cranes.

[0003] In existing technologies, when testing engine room trolleys, they are installed on a test bench and driven to move on the bench while carrying cargo to test their operational stability, load-bearing capacity, and braking performance. However, in reality, during operation, the wheels exert continuous pressure on the connecting frame track. Over time, the track surface gradually undergoes plastic deformation due to this long-term pressure, resulting in indentations on the inner track. This leads to poor contact between the trolley wheels and the track, causing periodic vibrations. However, the connecting frame track in existing test benches is generally straight, making it difficult to test engine room trolleys operating under track deformation and to adjust the track deformation. Therefore, there are deficiencies in the test items for engine room trolley experiments. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cabin crane test bench to solve the problems mentioned in the background art. This utility model can simulate the state of track deformation through the test bench, thereby conducting more detailed experiments on the cabin crane.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a cabin driving test bench, including a base plate and a cross plate, wherein a connecting plate is provided on the top of the base plate, and a bracket is fixedly connected to the top of the connecting plate by bolts.

[0006] The top of the bracket is fixedly connected to a connecting frame by bolts. The inner side of the connecting frame has multiple sets of recessed grooves, and cylindrical pins are slidably connected to the inner side of the recessed grooves. The cylindrical pins are fixed to both sides of the rotating plate. The inner side of the recessed grooves has a strip-shaped groove. One side of the rotating plate is movably connected to a horizontal plate through a rotating shaft. Fixing blocks are provided on both sides of the horizontal plate, and the top of the fixing blocks is wedge-shaped. One side of the fixing blocks is welded and fixed to the connecting frame. An adjustment mechanism is provided at the bottom of the horizontal plate.

[0007] Furthermore, the adjustment mechanism includes a hydraulic rod a fixedly connected to the bottom of the horizontal plate, a fixed seat fixedly connected to the bottom of the hydraulic rod a, and the top of the fixed seat welded and fixed to the connecting frame.

[0008] Furthermore, a rubber pad is connected to the top of the connecting plate, and multiple sets of the rubber pad are provided and are evenly distributed on the top of the connecting plate.

[0009] Furthermore, a fixing seat is welded and fixed at the center of the top of the base plate, and a connecting ball is rolled to the inner side of the fixing seat via ball bearings. The top of the connecting ball is connected and fixed to the connecting plate, and a shaking test mechanism is provided around the top of the base plate.

[0010] Furthermore, the shaking test mechanism includes a hydraulic rod b fixedly installed around the top of the base plate, a rolling ball being rotatably connected to the top of the hydraulic rod b, and grooves being formed around the bottom of the connecting plate, with the grooves being rotatably connected to the rolling ball.

[0011] Furthermore, a counterweight box is provided on the top of the rotating plate, and a counterweight block a is provided inside the counterweight box. A connecting ring is welded and fixed to the top of the counterweight block a, and a connecting rod is welded and fixed to the bottom of the counterweight block a. Multiple sets of counterweight blocks b are connected through the outside of the connecting rod, and a limit mechanism is provided inside the connecting rod.

[0012] Furthermore, the limiting mechanism includes an insert rod that penetrates the interior of the connecting rod, the interior of the counterweight b is slidably connected to the insert rod, and a threaded rod is fixed to one end of the insert rod near the connecting rod, the outer side of the threaded rod being threadedly connected to the counterweight b.

[0013] The beneficial effects of this utility model are as follows: When testing the engine room trolley, in order to simulate the deformation state of the track on the connecting frame, the hydraulic rod a is activated to drive the horizontal plate downward. The horizontal plate pulls the rotating plate downward, causing the cylindrical pin on one side to slide in the strip groove, thereby causing the two sets of rotating plates to rotate to an inclined state. The two sets of fixed blocks support the two sides of the rotating plate. At this time, the two sets of rotating plates and the horizontal plate will be in a concave state, and multiple sets of pits will be formed on the track of the connecting frame. When the engine room trolley moves on the connecting frame and comes into contact with the pits, it will shake. In this way, the stability of the engine room trolley can be tested by moving on the connecting frame in a deformed state. The PLC controls the activation of multiple sets of hydraulic rods b to extend or retract, thereby pushing the connecting plate to rotate. The connecting plate will swing around the connecting ball at the bottom in the fixed seat, thereby simulating the swaying of a ship when the sea is rough, and testing the stability of the engine room trolley. In this way, the above operation can facilitate the experiment of the engine room trolley under track deformation state. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1-2 This utility model provides a technical solution: a cabin driving test bench, including a base plate 1 and a cross plate 6. A connecting plate 2 is provided on the top of the base plate 1, and a bracket 3 is fixedly connected to the top of the connecting plate 2 by bolts.

[0024] Please see Figures 1-6The top of the bracket 3 is fixedly connected to the connecting frame 4 by bolts. The inner side of the connecting frame 4 has multiple sets of recessed grooves, and the inner side of the recessed grooves is slidably connected to the cylindrical pins 23. The cylindrical pins 23 are fixed to both sides of the rotating plate 5. The inner side of the recessed grooves has strip-shaped grooves. One side of the rotating plate 5 is movably connected to the horizontal plate 6 by a rotating shaft. The two sides of the horizontal plate 6 are provided with fixing blocks 7, and the top of the fixing blocks 7 is wedge-shaped. One side of the fixing blocks 7 is welded and fixed to the connecting frame 4. The bottom of the horizontal plate 6 is provided with an adjustment mechanism. The adjustment mechanism includes a hydraulic rod a8 fixedly connected to the bottom of the horizontal plate 6. The bottom of the hydraulic rod a8 is fixedly connected to a fixing seat 22, and the top of the fixing seat 22 is welded and fixed to the connecting frame 4. The top of the connecting plate 2 is connected with rubber pads 9. Multiple sets of rubber pads 9 are provided and are evenly distributed on the top of the connecting plate 2. The strip-shaped grooves opened on the inner side of the recessed grooves allow the cylindrical pins 23 on both sides of the rotating plate 5 to slide, so that the rotating plate 5 can rotate when the horizontal plate 6 moves.

[0025] Please see Figure 1 , Figure 2 and Figure 5 A fixed base 11 is welded and fixed at the center of the top of the base plate 1. A connecting ball 12 is rolled and connected to the inner side of the fixed base 11 via ball bearings. The top of the connecting ball 12 is connected and fixed to the connecting plate 2. A shaking test mechanism is provided around the top of the base plate 1. The shaking test mechanism includes a hydraulic rod b10 fixedly installed around the top of the base plate 1. A rolling ball 13 is rolled and connected to the top of the hydraulic rod b10. A groove 14 is provided around the bottom of the connecting plate 2, and the groove 14 is rolled and connected to the rolling ball 13. A counterweight box 15 is provided on the top of the rotating plate 5. A counterweight block a16 is provided inside the counterweight box 15. A connecting ring 17 is welded and fixed to the top of the counterweight block a16. A connecting rod 18 is welded and fixed to the bottom of the counterweight block a16. The outer side of the connecting rod 18 passes through... Multiple sets of counterweights b19 are connected, and a limiting mechanism is provided inside the connecting rod 18. The limiting mechanism includes an insert rod 20 that passes through the inside of the connecting rod 18. The inside of the counterweight b19 is slidably connected to the insert rod 20. A threaded rod 21 is fixed at one end of the insert rod 20 near the connecting rod 18. The outer side of the threaded rod 21 is threadedly connected to the counterweight b19. A through hole matching the insert rod 20 is opened inside the connecting rod 18. The connecting rod 18 and the insert rod 20 form a sliding structure, and the threaded rod 21 and the counterweight b19 form a threaded transmission structure. When multiple sets of balls are provided inside the fixed seat 11 and come into contact with the connecting ball 12, they can reduce the friction force when the connecting ball 12 rotates. The connecting ring 17 can facilitate the connection between the trolley and the counterweight a16, thereby enabling load testing.

[0026] Please see Figures 1-4In specific implementation, when the cabin crane test bench is used to test the cabin crane, in order to simulate the deformation state of the track on the connecting frame 4, the hydraulic rod a8 is activated to drive the horizontal plate 6 to move downward. The horizontal plate 6 will pull the rotating plate 5 to move, so that the cylindrical pin 23 on one side slides in the strip groove, thereby causing the two sets of rotating plates 5 to rotate to an inclined state. The two sets of fixing blocks 7 will support the two sides of the rotating plate 5. At this time, the two sets of rotating plates 5 and the horizontal plate 6 will be in a concave state, and multiple sets of pits will be formed on the track of the connecting frame 4. When the cabin crane moves on the connecting frame 4 and comes into contact with the pits, it will shake. In this way, the cabin crane moving on the connecting frame 4 in a deformed state can be tested, thereby measuring the stability of the cabin crane. When the deformation of the connecting frame 4 is not required, the hydraulic rod a8 can be activated to push the horizontal plate 6 upward. The horizontal plate 6 will make the rotating plate 5 return to a straight state and be flush with the track on the inner side of the connecting frame 4. At this time, the cabin crane can move smoothly.

[0027] Please see Figure 1 , Figure 2 and Figure 5 When simulating the rocking of a ship at sea, multiple hydraulic rods b10 can be extended or retracted via PLC control, thereby driving the connecting plate 2 to rotate. The connecting plate 2 will swing around the connecting ball 12 at the bottom in the fixed seat 11, thus simulating the rocking of a ship in rough seas, and testing the stability of the engine room crane. When testing the load capacity of the engine room crane, the hook of the engine room crane is connected to the connecting ring 17 at the top of the counterweight a16, and then the counterweight a16 is lifted. When the weight needs to be adjusted, the weight can be adjusted by... The insert rod 20 in counterweight b19 passes through the connecting rod 18. Then, rotating the insert rod 20 drives the threaded rod 21 to perform threaded transmission with the counterweight b19, completing the connection between counterweight a16 and counterweight b19. Depending on different test conditions, different numbers of counterweight b19 and counterweight a16 can be connected to adjust the load. The rotating plate 5 on the top of the connecting plate 2 can protect the connecting plate 2 and prevent the counterweight b19 and counterweight a16 from making direct hard contact with the connecting plate 2 when they fall. In this way, the above operation can facilitate the experiment of the engine room crane under track deformation conditions.
