[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-Figure 5 , an embodiment provided by the utility model:
[0023] A lifeboat load test device comprises a base 1, a vertical frame 2 is fixedly installed on the top of the base 1, a plurality of counterweight blocks 3 arranged in an up-and-down manner are placed inside the vertical frame 2, and the bottom of a lower counterweight block 3 is in contact with the top of the base 1, a ⊥-shaped groove 4 is provided on the front of the vertical frame 2, an inclined frame 5 is fixedly installed between the top of the base 1 and the two sides of the vertical frame 2, an L-shaped folding plate 6 is fixedly installed between the back of the vertical frame 2 and the top of the base 1, a hydraulic cylinder 7 is fixedly installed on the rear wall of the L-shaped folding plate 6, a U-shaped pushing plate 8 fixedly installed at the telescopic end of the hydraulic cylinder 7 has a height consistent with the smallest counterweight block 3 among the plurality of counterweight blocks 3, a display controller 9 installed on one side of the vertical frame 2 is electrically connected to the hydraulic cylinder 7, and a height difference ranging component 10 is fixedly installed on the front side of the bottom of the inclined frame 5.
[0024] In actual application, after combining the device with the lifeboat to be tested, the hydraulic cylinder 7 is controlled by the display controller 9 to perform forward extension and backward contraction operations accordingly. When it extends forward, it can correspondingly drive the U-shaped pushing plate 8 to move forward, and then generate a forward driving force for the lowest counterweight block 3, and push the larger part of the counterweight block 3 along the lower part of the ⊥-shaped groove 4 into the space inside the inclined frame 5, and then the counterweight block 3 can slide down along the bottom wall of the inclined frame 5 into the lifeboat, so as to achieve the purpose of autonomously adding weight to the lifeboat to be tested to gradually increase the load of the lifeboat, and after pushing one counterweight block 3, the hydraulic cylinder 7 immediately contracts backward to restore its original state, so that the second counterweight block 3 originally at the bottom falls down.
[0025] An adjusting seat 11 is movably installed at the bottom of the base 1, and a bidirectional screw 12 is rotatably connected between the inner walls on both sides of the adjusting seat 11. The top of a slide cylinder 13 threadedly sleeved on the outer surface of the bidirectional screw 12 is fixedly connected to the middle of the bottom of the base 1. A rocker 14 is installed on one side of the adjusting seat 11, and one side of it is fixedly connected to one end of the bidirectional screw 12. Two front and rear limit rods 15 fixedly installed between the inner walls on both sides of the adjusting seat 11 are respectively located in front and behind the bidirectional screw 12, and the top of a cylinder 16 slidably sleeved on the outer surface of the two limit rods 15 is fixedly connected to the bottom of the base 1.
[0026] When the rocker 14 is rotated, the bidirectional screw rod 12 can be driven to rotate in the set direction, so that the slide cylinder 13 moves toward one side along the outer surface of the bidirectional screw rod 12, and the base 1 follows and slides toward one side along the top of the adjustment seat 11. Based on this, the vertical frame 2, the tilting frame 5 and the height difference ranging assembly 10 follow the movement, so that when the counterweight block 3 is dropped onto the lifeboat through this device, the counterweight block 3 can be distributed more evenly on the lifeboat.
[0027] The engaging strip 22 slidably sleeved on the outer surface of the T-shaped cylinder 21 can be installed on one side of the top of the lifeboat to be tested, and in combination with the telescopic sleeve 20, the connection between the test device and the lifeboat to be tested can be increased. The circular groove with the same diameter as the bottom of the T-shaped cylinder 21 is provided on the top of the engaging strip 22, which can facilitate the combination of the T-shaped cylinder 21 and the engaging strip 22. The elastic bands 23 installed on both sides of the front end of the tilting frame 5 can relieve the impact force when the counterweight 3 slides down along the bottom wall of the tilting frame 5. In addition, the elastic bands 23 in the device are installed relatively loosely, so while relieving the impact force of the counterweight 3 sliding down, it does not affect the counterweight 3 sliding out of the inside of the tilting frame 5. In addition, because the T-shaped cylinder 21 can slide left or right along the inside of the engaging strip 22 under the action of external force, it is convenient for the T-shaped cylinder 21 and the base 1 to keep moving at the same speed when the rocker 14 is turned.
[0028] The structure of the height difference ranging component 10 includes a leveling plate 17, a first ultrasonic ranging sensor 18 and a second ultrasonic ranging sensor 19. The leveling plate 17 is fixedly installed at the bottom of the tilting frame 5. The first ultrasonic ranging sensor 18 and the second ultrasonic ranging sensor 19 are installed at the bottom of the leveling plate 17 in a front-to-back interlocking manner. The structure of the height difference ranging component 10 also includes a telescopic sleeve 20 and a T-shaped cylinder 21. The telescopic sleeve 20 is fixedly installed at the bottom of the leveling plate 17, and the telescopic sleeve 20 is located between the first ultrasonic ranging sensor 18 and the second ultrasonic ranging sensor 19 arranged front and back. The T-shaped cylinder 21 is fixedly installed at the bottom of the telescopic sleeve 20.
[0029] The telescopic sleeve 20 is telescopic. In the process of adding weight to the lifeboat, the lifeboat will sink into the water. In addition, since the height of the main structure of the device remains unchanged, it shows that the distance between the tilting frame 5 and the lifeboat below it is gradually increasing, and the telescopic sleeve 20 can follow the downward extension length. Moreover, since the T-shaped cylinder 21 and the engaging strip 22 installed on the lifeboat are combined with each other, the relative position between the tail end of the tilting frame 5 and the lifeboat can be effectively limited. At this time, the first ultrasonic ranging sensor 18 is located above the water surface and the second ultrasonic ranging sensor 19 is located on one side of the top of the lifeboat. In actual application, each time a counterweight block 3 is added to the lifeboat, the distance between the first ultrasonic ranging sensor 18 and the water surface below is compared with the distance between the second ultrasonic ranging sensor 19 and the lifeboat below. The height difference between the two is used to determine whether the lifeboat is overweight, and the height difference between the two is displayed on the display controller 9, which is convenient for the staff to understand intuitively.
[0030] Working principle: The staff installs the fitting strip 22 on one side of the top of the lifeboat to be tested, and combines the T-shaped cylinder 21 with the fitting strip 22 along the circular groove. At this time, the first ultrasonic ranging sensor 18 is located above the water surface and the second ultrasonic ranging sensor 19 is located on one side of the top of the lifeboat. Then, the display controller 9 controls the hydraulic cylinder 7 to extend forward, so that the U-shaped pushing plate 8 generates a forward thrust on the counterweight block 3 at the bottom of the vertical frame 2, and pushes the larger part of the counterweight block 3 along the lower part of the ⊥-shaped groove 4 into the space inside the tilting frame 5, and then the counterweight block 3 can slide downward autonomously along the bottom wall of the tilting frame 5. To the lifeboat, so as to achieve the purpose of autonomously adding weight to the lifeboat to be tested to gradually increase the load of the lifeboat, and then by starting the first ultrasonic ranging sensor 18 and the second ultrasonic ranging sensor 19 electrically connected to the hydraulic cylinder 7, the first ultrasonic ranging sensor 18 monitors the distance between itself and the water surface below, and the second ultrasonic ranging sensor 19 monitors the distance between itself and the lifeboat below. The height difference between the two is used to determine whether the lifeboat is overweight, and the height difference between the two is displayed on the display controller 9, which is convenient for the staff to understand intuitively. After that, the load capacity of the lifeboat is tested by repeatedly adding counterweight blocks 3 and ranging operations to the lifeboat.
