Description

Technical Field

[0001] This utility model belongs to the field of impact testing technology, and in particular relates to a gas cylinder impact testing device. Background Technology

[0002] To ensure the safety of gas cylinders in actual use, they must undergo rigorous impact resistance tests after production to verify their sufficient impact resistance. Impact resistance testing equipment typically uses principles such as free fall to simulate the impact of external gravel or other sharp objects on the cylinder surface, thereby assessing the cylinder's impact resistance.

[0003] During the test, a certain mass of crushed stone or steel shot is placed in a specific device, and its falling speed, angle and number of impacts are controlled so that the crushed stone or steel shot impacts the surface of the gas cylinder under test with a certain amount of energy.

[0004] However, existing gas cylinder impact testing machines cannot guarantee the stability of the impacting object during free fall, which makes it impossible to accurately conduct impact tests on the parts of the gas cylinder to be tested, thus affecting the accuracy of the gas cylinder impact test and failing to meet the testing requirements. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] A typical embodiment of this utility model is as follows: Figure 1 As shown, a gas cylinder impact testing device includes a support platform 1, a support frame 2 is provided on the upper surface of the support platform 1, the support frame 2 is a frame structure, and a plurality of guide rods 3 are provided inside the support frame 2. In this embodiment, there are two guide rods 3, which are arranged in parallel. The bottom end of the guide rod 3 is fixedly connected to the support platform 1, and the top end of the guide rod 3 is connected through a connecting plate. A movable plate 5 is also provided inside the support frame 2. The two ends of the movable plate 5 are slidably connected to the two guide rods 3 respectively, so that the movable plate 5 can slide along the guide rods 3.

[0026] The lower surface of the movable plate 5 is provided with an impact weight 6. In use, the gas cylinder is fixed on the support platform 1 and located directly below the impact weight 6. After the movable plate 5 rises to the set height along the guide rod 3, it is allowed to fall freely to impact the gas cylinder. By interactively connecting the movable plate 5 and the guide rod 3, the guide rod 3 can ensure the stability of the movable plate 5 during its descent, thereby ensuring the accuracy of the test structure.

[0027] A shock-absorbing spring 7 is fitted on the bottom outer surface of the guide rod 3, which can buffer the fall of the moving plate 5 and thus protect the moving plate 5.

[0028] Furthermore, a groove 8 is provided on the upper surface of the support platform 1. The width of the groove 8 is greater than the width of the gas cylinder, so that the gas cylinder can be placed in the groove 8. A gas cylinder clamping device is provided in the groove 8. The gas cylinder clamping device is located directly below the moving plate 5. The gas cylinder is fixed on the support platform 1 by the gas cylinder clamping device.

[0029] The gas cylinder clamping device includes a first clamping claw 9 and a second clamping claw 10. The first clamping claw 9 and the second clamping claw 10 are symmetrically arranged. The first clamping claw 9 is rotatably connected to one side wall of the groove 8 through a first connecting rod, and the second clamping claw 10 is rotatably connected to the other side wall of the groove 8 through a second connecting rod.

[0030] Specifically, a threaded hole is provided on the side wall of the groove 8 opposite to the first clamping claw 9, and an external thread that matches the threaded hole is provided on the outer surface of the second connecting rod, thereby realizing the threaded connection between the second connecting rod and the side wall of the groove 8. The end of the second connecting rod close to the first clamping claw 9 is rotatably connected to the second clamping claw 10, and the end of the second connecting rod away from the first clamping claw 9 is fixedly connected to the first handwheel 11.

[0031] The connection between the second clamping claw 10 and the side wall of the groove 8 is the same as the connection between the first clamping claw 9 and the side wall of the groove 8, and will not be repeated here.

[0032] The first clamping claw 9 and the second clamping claw 10 both have arc-shaped cross sections. When the first handwheel 11 on both sides of the support platform 1 is rotated, due to the threaded connection between the first connecting rod and the side wall of the groove 8, and the threaded connection between the second connecting rod and the side wall of the groove 8, the first clamping claw 9 can move along the axial direction of the first connecting rod, and the second clamping claw 10 can move along the axial direction of the second connecting rod. The gas cylinder is placed between the first clamping claw 9 and the second clamping claw 10. Rotating the first handwheel 11 controls the first clamping claw 9 and the second clamping claw 10 to move towards the gas cylinder, thereby clamping and fixing the gas cylinder placed between the first clamping claw 9 and the second clamping claw 10.

[0033] By setting the first clamping claw 9 and the second clamping claw 10, the gas cylinder clamping device can grasp the gas cylinder at any position, thereby enabling impact tests on different parts of the gas cylinder. Furthermore, the position of the gas cylinder can be adjusted at any time during the impact test, improving its flexibility.

[0034] Because the impact weight 6 is relatively heavy, a lifting device is also provided to facilitate lifting the moving plate 5 to the set height. The lifting device is fixed on the support platform 1. The lifting device can control the moving plate 5 to rise or fall, thereby raising the moving plate 5 to the set height for easy impact testing.

[0035] The lifting device includes a fixed plate 12, which is located on one side of the support platform 1 and is fixedly connected to the support platform 1. A second handwheel 14 and a drive pulley 17 are provided on the fixed plate 12. The second handwheel 14 is connected to the drive pulley 17 through a gear transmission mechanism, thereby controlling the rotation of the drive pulley 17 by the second handwheel 14.

[0036] Specifically, a fixing block 13 is provided on the upper surface of the fixing plate 12. A first support rod is threadedly connected to the fixing block 13. The first support rod is rotatably connected to the fixing block 13. A second handwheel 14 is fixedly connected to one end of the first support rod. A first bevel gear 15 is fixedly connected to the end of the first support rod away from the second handwheel 14. The first bevel gear 15 meshes with a second bevel gear 16. The second bevel gear 16 is sleeved on the second support rod and is rotatably connected to the second support rod. Both ends of the second support rod are fixedly connected to the fixing plate 12 through bearing seats. The second support rod is perpendicular to the first support rod.

[0037] The fixed plate 12 is also provided with an active pulley 17. The active pulley 17 is located on one side of the upper surface of the fixed plate 12. A rotating shaft is provided at the axis of the active pulley 17. The rotating shaft is rotatably connected to the support plates located on both sides of the active pulley 17. A first gear 18 is fixedly connected to one end of the rotating shaft near the second support rod. The first gear 18 meshes with the second gear 19. The second gear 19 is sleeved on the second support rod.

[0038] Rotating the second handwheel 14 causes the second support rod to rotate by meshing between the first bevel gear 15 and the second bevel gear 16, while simultaneously causing the drive pulley 17 to rotate by meshing between the first gear 18 and the second gear 19.

[0039] The second handwheel 14 and the drive pulley 17 are connected by a gear set. By utilizing the labor-saving characteristics of the gear set, the moving plate 5 can be easily lifted to the set height, and the stability of the moving plate 5 during lifting is ensured.

[0040] A top pulley 20 is provided on the bottom surface of the top plate 4 of the support frame 2. The top pulley 20 is located above the moving plate 5. A chain is wound on the drive pulley 17. One end of the chain passes around the top pulley 20 and is fixedly connected to the upper surface of the moving plate 5. When the drive pulley 17 rotates, the chain drives the moving plate 5 to rise along the guide rod 3 under the action of the top pulley 20, so that the moving plate 5 reaches different heights and conducts impact tests at different heights to meet the test requirements.

[0041] Working principle

[0042] In use, first place the gas cylinder on the fixed platform, between the first and second clamping claws. Rotate the first handwheel to fix the gas cylinder, thereby securing it and providing stability. Then, rotate the second handwheel, which, through the first and second bevel gears and the first and second gears, drives the drive pulley to rotate. The top pulley then moves the moving plate up the guide column to the set height. Release the second handwheel to allow the moving plate to descend freely. An impact test is then conducted on the gas cylinder using an impact weight on the lower surface of the moving plate. During the descent, the shock-absorbing spring protects the moving plate from the impact. Finally, a safety inspection is performed on the gas cylinder after the impact test to observe whether it meets the standard requirements.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
