[0001] The utility model relates to the technical field of metal hose vibration reduction performance testing, in particular to a metal hose vibration reduction performance testing device. Background Art

[0002] Metal hoses are flexible pipes made of metal. They are often used to connect various pipes and equipment. Vibration can cause joints to loosen and seals to fail, leading to leaks or equipment failure. Vibration damping testing can help evaluate the hose's performance under vibration, ensuring it can effectively absorb and reduce vibration, protecting the overall performance of the equipment.

[0003] In the prior art, there is a patent document with publication number CN217586223U, which discloses a metal hose vibration damping performance test device. The patent document has a mounting bracket, a vibration device, a drive device and a detection component. The mounting bracket includes two fixed plates arranged opposite to each other, and an adjustment plate movably arranged between the two fixed plates along a connecting rod. The two ends of the metal hose are respectively fixed to the vibration device and the adjustment plate; the drive device is used to drive the vibration device to drive the metal hose to swing back and forth; the vibration detector is used to detect the vibration value generated by different parts of the metal hose under the action of the vibration device. The metal hose vibration damping performance test device using this technical solution can quantitatively analyze the vibration damping performance of the metal hose and the fatigue life under high-frequency vibration, so as to test the service life of metal hoses of different lengths. It meets the dynamic performance test requirements of the metal hose and has guiding significance in the pipeline design, process improvement and other aspects of the metal hose.

[0004] The above-mentioned and existing technologies have the following defects: when testing metal hoses, since the lengths of metal hoses in each batch are different, the position of the adjustment plate needs to be adjusted when testing metal hoses of different lengths. Since the existing adjustment method uses manual pushing of the adjustment plate for adjustment, manual adjustment increases the subjective factors of the operator, which may result in inaccurate adjustment and require multiple fine-tuning. This will significantly increase the total test time and reduce test efficiency.

[0005] Therefore, a metal hose vibration reduction performance testing device is proposed. Utility Model Content

[0009] Preferably, a groove is provided on one side of the baffle, and a protective pad is fixedly connected to the inner wall of the groove.

[0010] The effect achieved by the above components is that the baffle drives the protective pad to fit tightly to the other end of the metal hose body, and the protective pad prevents the baffle from fitting to the metal hose body, causing wear on one end of the metal hose body.

[0014] The effect achieved by the above components is: the limit plate will drive the anti-slip strip to fit tightly against the inner wall of the U-shaped plate, and the anti-slip strip increases the friction between the limit plate and the inner wall of the U-shaped plate, further improving the limiting effect on the baffle position.

[0030] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0032] like Figure 1 - Figure 2 As shown, the utility model provides a metal hose vibration reduction performance testing device, including a workbench 1, a first fixing plate 2 is fixedly connected to the surface of the workbench 1, a second fixing plate 3 is fixedly connected to the surface of the workbench 1, a plurality of fixing rods are fixedly connected to the side where the first fixing plate 2 and the second fixing plate 3 are close to each other, an adjustment plate 4 is slidably connected to the surface of the plurality of fixing rods, and a mounting joint 5 is fixedly connected to the side where the adjustment plate 4 and the first fixing plate 2 are close to each other, a vibration detector 12 is installed on the surface of the mounting joint 5, a metal hose body 11 is installed on the surfaces of the two mounting joints 5, and the surface of the workbench 1 is fixed. It is connected to a motion motor 6, and the output end of the motion motor 6 is covered with a conveyor belt 7. The surface of the second fixed plate 3 is slidably penetrated by two adjustment rods 10, and the two adjustment rods 10 are fixedly connected to the surface of the adjustment plate 4. The surfaces of the first fixed plate 2 and the second fixed plate 3 are provided with a driving structure 8. By providing the driving structure 8, it is convenient to adjust the position of the adjustment plate 4 according to the length of the metal hose body 11, thereby avoiding the need to repeatedly adjust the position of the adjustment plate 4, and then facilitating the installation of the metal hose body 11 on the installation joint 5, reducing the time occupied by the installation and improving the efficiency of the test of the metal hose body 11. The surface of the workbench 1 is provided with an adjustment structure 9. By providing the adjustment structure 9, it is convenient to tighten the loose conveyor belt 7, thereby improving the transmission effect of the conveyor belt 7, and then ensuring the effect of the shock absorption performance test of the metal hose.

[0033] The specific settings and functions of the driving structure 8 and the regulating structure 9 are described in detail below.

[0034] like Figure 3 and Figure 4As shown, the driving structure 8 includes two side plates 801, and the two side plates 801 are fixedly connected to the first fixed plate 2 and the second fixed plate 3 respectively. The side of the two side plates 801 close to each other is rotatably connected to the screw rod 802, and the surface of the second fixed plate 3 is fixedly connected to the servo motor 803, and the output end of the servo motor 803 is fixedly connected to the screw rod 802. The surface of the screw rod 802 is threadedly connected to the driving plate 813, and the driving plate 813 is fixedly connected to the surface of the adjusting plate 4. The side of the two side plates 801 close to each other is fixedly connected to the U-shaped plate 804, and the surface of the U-shaped plate 804 is slidingly covered with a baffle 805, and one side of the baffle 805 is fixedly connected to an extension plate 806, and the surface of the extension plate 806 is threaded with a screw rod 807, and one end of the screw rod 807 is rotatably connected to the limiting plate 808. A groove 809 is formed on one side of the baffle 805, and a protective pad 810 is fixedly connected to the inner wall of the groove 809. The baffle 805 drives the protective pad 810 to fit tightly against the other end of the metal hose body 11. The protective pad 810 prevents the baffle 805 from fitting against the metal hose body 11, which could cause wear on one end of the metal hose body 11. A turntable 811 is fixedly connected to the end of the screw 807 away from the limit plate 808. The cross-section of the turntable 811 is in the shape of a cross. Rotating the turntable 811 drives the screw 807 to rotate, facilitating the rotation of the screw 807. Several anti-slip strips 812 are fixedly connected to the surface of the limiting plate 808. The cross-section of the anti-slip strips 812 is arc-shaped. The limiting plate 808 will drive the anti-slip strips 812 to fit tightly against the inner wall of the U-shaped plate 804. The anti-slip strips 812 increase the friction between the limiting plate 808 and the inner wall of the U-shaped plate 804, further improving the limiting effect on the position of the baffle 805.

[0035] like Figure 5 As shown, the adjustment structure 9 includes a rectangular plate 91, which is fixedly connected to the surface of the workbench 1. A threaded rod 92 is threadedly passed through the surface of the rectangular plate 91, and a pressure block 93 is fixedly connected to the end of the threaded rod 92 near the conveyor belt 7. Both sides of the rectangular plate 91 are fixedly connected to a limit arm 94, and a round rod 95 is slidably passed through the surface of the limit arm 94. The round rod 95 is fixedly connected to the surface of the pressure block 93. During the movement of the pressure block 93, the round rod 95 is driven to slide within the limit arm 94. The limit arm 94 limits the movement path of the round rod 95, and then limits the movement path of the pressure block 93, thereby preventing the pressure block 93 from rotating during movement. A rectangular groove 96 begins to appear on the surface of the pressing block 93, and the inner wall of the rectangular groove 96 is rotatably connected to a rotating wheel 97. The pressing block 93 will drive the rotating wheel 97 to squeeze the conveyor belt 7. When the conveyor belt 7 is working, the rotating wheel 97 will drive the rotating wheel 97 to rotate in the rectangular groove 96. The rotating wheel 97 reduces the friction between the conveyor belt 7 and the pressing block 93, thereby further reducing the energy consumption of the motion motor 6.

[0036] The overall working principle is that when the position of the adjustment plate 4 needs to be adjusted according to the length of the metal hose body 11, the turntable 811 is first rotated. The rotation of the turntable 811 will drive the screw 807 to rotate. The rotation of the screw 807 will move in the extension plate 806 with the help of the thread. The movement of the screw 807 will drive the limit plate 808 to move away from the U-shaped plate 804. When the curved plate moves to the appropriate position, the metal hose body 11 is placed in the curved plate so that one end of the metal hose body 11 is attached to the inner wall of the U-shaped plate 804, and then the baffle 805 is pushed. 05 will move closer to one end of the metal hose body 11. When the baffle 805 moves to a suitable position, the baffle 805 will drive the protective pad 810 to fit tightly against the other end of the metal hose body 11. The protective pad 810 can prevent the baffle 805 from fitting against the metal hose body 11, which may cause wear on one end of the metal hose body 11. Then, the turntable 811 is rotated in the opposite direction. The screw 807 drives the limit plate 808 to move closer to the U-shaped plate 804 with the help of the turntable 811. When the limit plate 808 moves to a suitable position, After that, the limit plate 808 will drive the anti-slip strip 812 to fit tightly against the inner wall of the U-shaped plate 804, and the limit plate 808 will reach the position of the limiting baffle 805. The anti-slip strip 812 can increase the friction between the limit plate 808 and the inner wall of the U-shaped plate 804, further improving the limiting effect on the position of the baffle 805. Then adjust the limit structure on the adjustment rod, remove the limit structure, and then drive the servo motor 803. The rotation of the servo motor 803 will drive the screw rod 802 to rotate, and the rotation of the screw rod 802 will drive the driving plate 813 to move with the help of the thread, and the driving plate 813 moves. The movement will drive the adjustment plate 4 to move, and the adjustment plate 4 will slide along the surface of the fixed rod when moving. The adjustment plate 4 will drive the adjustment rod 10 to slide in the second fixed plate 3 when moving. When the adjustment plate 4 moves to a suitable position, the driving plate 813 will fit on the surface of the baffle 805, and the baffle 805 reaches the position of limiting the driving plate 813, thereby limiting the moving position of the adjustment plate 4, so as to facilitate adjusting the position of the adjustment plate 4 according to the length of the metal hose body 11, and then tighten the limiting structure on the adjustment rod 10 to limit the position of the adjustment plate 4.

[0037] When the conveyor belt 7 becomes loose, the threaded rod 92 is first rotated. The rotation of the threaded rod 92 will move in the rectangular plate 91 with the help of the thread. The movement of the threaded rod 92 will drive the pressure plate to move in the direction close to the conveyor belt 7. During the movement, the pressure block 93 will drive the round rod 95 to slide in the limiting arm 94. The limiting arm 94 limits the moving path of the round rod 95, and then limits the moving path of the pressure block 93, thereby preventing the pressure block 93 from rotating during movement. When the pressure block 93 moves to the appropriate position, the pressure block 93 will drive the rotating wheel 97 to squeeze the conveyor belt 7 until the conveyor belt 7 is tightened. At this time, the conveyor belt 7 will drive the rotating wheel 97 to rotate in the rectangular groove 96 when working. The rotating wheel 97 reduces the friction between the conveyor belt 7 and the pressure block 93, thereby further reducing the energy consumption of the motion motor 6.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
