Description

Technical Field

[0001] The utility model relates to a lateral displacement limiter of a lightweight strong impact test bench. Background Art

[0002] The lightweight strong impact test system is a test instrument defined in military standards. It mainly simulates the strong impact of ship machinery, equipment and systems (hereinafter referred to as equipment) with a total mass less than 200kg caused by underwater explosions, close-range off-target artillery fire, etc. that ships may encounter during combat, and assesses and evaluates the ability of ship equipment to withstand strong impacts.

[0003] The lightweight strong impact test system is driven by a motor to lift the pendulum and vertical impact hammer to the set height to impact the table surface, simulating the impact of the explosive environment on the test piece installed on the work surface. Its main mechanical table body includes impact frame, impact hammer, lateral displacement limiter, buffer spring group, lifting release mechanism, work surface and other parts.

[0004] The lateral displacement limiter plays a buffering and limiting role when a horizontal side impact is carried out at the same time. The lateral displacement limiter and the impact test bench are usually set separately. After the impact frame is fixed, the lateral displacement limiter must also be fixed to ensure that its position is aligned with the side of the impact frame, and the distance between the lateral displacement limiter and the bottom of the impact frame needs to be adjusted to meet the test requirements of the impacted object. However, due to the separate setting of the lateral displacement limiter and the impact test bench, the adjustment process is relatively cumbersome, which directly affects the efficiency of the impact test.

[0027] Reference Figure 1-6 The utility model proposes a lateral displacement limiter of a lightweight strong impact test bench, comprising a guide rail assembly 2 and a lateral displacement limiting assembly 3 installed on one side of an impact frame 1, and a fixing assembly 4 matching the guide rail assembly 2 is provided on the lateral displacement limiting assembly 3;

[0028] Reference Figure 4 The guide rail assembly 2 includes two guide rails 21 installed on one side of the bottom of the impact frame 1, and a plurality of positioning grooves 22 are provided on the two guide rails 21. Slots 23 are provided on both sides of the positioning grooves 22, and plug-ins 24 are installed in the slots 23;

[0029] In this embodiment, the guide rail assembly 2 is fixed to one side of the bottom of the impact frame 1, and includes two guide rails 21. Each guide rail 21 is provided with a plurality of positioning grooves 22 with uniform intervals, which are convenient for adjusting and optimizing the fixed position of the lateral displacement limiting assembly 3. Slots 23 are also provided on both sides of the positioning grooves 22. The slots 23 are equipped with plug-ins 24. The plug-ins 24 are used to limit the fixing parts in the fixing assembly 4 in the positioning grooves 22, thereby fixing the fixing assembly 4 and limiting the movement of the lateral displacement limiting assembly 3.

[0030] Reference Figure 5 The lateral displacement limiting component 3 includes an L-shaped plate 31, a plurality of reinforcing plates 32 are connected to the inner side of the L-shaped plate 31, a plurality of mounting holes 33 are opened on the front side of the L-shaped plate 31, and buffer components 5 are correspondingly installed in the plurality of mounting holes 33, and the fixing component 4 is installed on the bottom plate of the L-shaped plate 31.

[0031] In this embodiment, the lateral displacement limiting component 3 includes an L-shaped plate 31, and a reinforcing plate 32 is arranged between two vertical plates to make the overall structure more stable. A plurality of mounting holes 33 are provided on the plate of the L-shaped plate 31 perpendicular to the ground, and a buffer component 5 is installed inside the L-shaped plate 31, and a fixing component 4 is installed on the plate parallel to the ground.

[0034] In this embodiment, a worker steps on the pedal 43 to rotate it around the rotating hole 42, so that the fixing rod 45 in the sleeve 44 installed at the bottom of the pedal 43 moves along with it until it moves into the positioning groove 22. At this time, the plug-in 24 is inserted into the slot 23 to fix the fixing rod 45 in the positioning groove 22. The multiple anti-slip grooves on the pedal increase the friction between the operator and the pedal, reducing the risk of sliding.

An extension plate 54 is also fixed to the outside of the connecting plate 53. A compression spring 55 is also sleeved on the support rod 51. The compression spring 55 is placed on the outer side of the L-shaped plate 31 and acts between the outer side of the L-shaped plate 31 and the inner side of the connecting plate 53.

[0036] Specifically, the size of the extension plate 54 should be at least larger than the size of the connection plate 53 , and the size of the limiting plate 52 should be at least larger than the maximum size between the plurality of support rods 51 .

[0037] In this embodiment, the buffer assembly 5 can effectively absorb and disperse the impact energy, reduce the force directly acting on the test bench body, and increase the stability of the structure through the design of the extension plate and the limit plate to prevent the buffer assembly from being displaced or falling off under extreme conditions.

[0038] Reference Figure 1-3 The fixing assembly 4 is integrally arranged on the inner side of the L-shaped plate 31 close to the plate angle, and the overall size of the L-shaped plate 31 does not exceed the size between the two guide rails 21.

The top of the L-shaped plug block 241 is connected to a baffle 242, and a pull ring 243 is installed on the top of the baffle 242.

[0040] In this embodiment, by optimizing the structural design and adding a buffer mechanism, the lateral displacement limiter can effectively resist impact forces from different directions, reduce displacement and damage during the test, and ensure the accuracy and reliability of the test data.
