Description

Technical Field

[0002] A viscous damper is a damper that is related to the speed of piston movement. It is widely used in high-rise buildings, bridges, seismic retrofitting of building structures, seismic resistance of industrial pipeline equipment, military industry and other fields. Its working principle is based on fluid movement. When the fluid passes through the throttling hole, throttling resistance will be generated.

[0003] The main structure of a common viscous damper includes a cylinder, a piston, a piston rod and a pin. The piston rod is subjected to force to drive the piston to move in the cylinder. When the viscous medium passes through the throttle hole on the piston, resistance is generated to offset the force on both ends of the piston rod. In order to ensure that the viscous medium does not leak from the cylinder, it is necessary to test the sealing of the cylinder when manufacturing the viscous damper. The existing testing process is a static pressure holding test, in which a medium with a constant pressure is passed into the cylinder to observe whether the cylinder leaks. However, this test cannot reflect the actual working scenario of the viscous damper. When in use, the viscous damper may be subjected to continuous lateral shock waves, which act on the viscous damper at a pulse frequency and destroy the sealing of the cylinder.

[0032] like Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, it includes an active detection mechanism 100 and a damper fixing mechanism 200, the active detection mechanism 100 includes a rotating pushing component 101 and a sliding connection component 102, and the two ends of the viscous damper to be detected are respectively connected to the active detection mechanism 100 and the damper fixing mechanism 200, wherein the rotating pushing component 101 and the sliding connection component 102 are arranged on the damper fixing mechanism 200, the sliding connection component 102 and the damper fixing mechanism 200 are slidingly connected, a driven wheel 112 is provided on the sliding connection component 102, the driven wheel 112 and the sliding connection component 102 are rotationally connected, the rotating pushing component 101 includes an active wheel 103 and a biasing block 104, the biasing block 104 is arranged on the active wheel 103, and the active wheel 103 and the damper fixing mechanism 200 are rotationally connected.

[0033] The rotation axes of the driving wheel 103 and the driven wheel 112 are on the same horizontal plane. The driving wheel 103 is configured to drive the biasing block 104 to push the driven wheel 112 when rotating, and the driven wheel 112 is configured to slide on the damper fixing mechanism 200 when under pressure.

[0034] In this embodiment, this embodiment proposes a device for detecting the sealing of a viscous damper, including a movable detection mechanism 100 and a damper fixing mechanism 200, wherein two ends of the viscous damper to be detected are respectively connected to the movable detection mechanism 100 and the damper fixing mechanism 200, wherein the end of the viscous damper to be detected connected to the damper fixing mechanism 200 remains fixed, and the end of the viscous damper to be detected connected to the movable detection mechanism 100 is movable, and the specific structure of the movable detection mechanism 100 includes a rotating pushing component 101 and a sliding connection component 102, wherein the rotating pushing component 101 rotates relative to the damper fixing mechanism 200, and the sliding connection component 102 slides relative to the damper fixing mechanism 200, and a continuously periodically changing thrust is applied to one end of the viscous damper to be detected through the cooperation of the sliding connection component 102 and the rotating pushing component 101, thereby simulating the vibration of the viscous damper to be detected in the working environment, and then observing whether the viscous damper to be detected leaks and judging its sealing.

[0035] Specifically, the rotating pushing assembly 101 includes an active rotating wheel 103 and an offset block 104, and a driven rotating wheel 112 is arranged on the sliding connection assembly 102, wherein the offset block 104 is arranged on the active rotating wheel 103, the active rotating wheel 103 rotates relative to the damper fixing mechanism 200, and the driven rotating wheel 112 rotates relative to the sliding connection assembly 102, and the offset block 104 is arranged on the active rotating wheel 103 and is higher than the surface of the active rotating wheel 103, and when the active rotating wheel 103 rotates, the offset block 104 is driven to rotate synchronously, and when the offset block 104 contacts the driven rotating wheel 112, it interferes with the driven rotating wheel 112, and then pushes the sliding connection assembly 102 to slide on the damper fixing mechanism 200 through the driven rotating wheel 112, and the sliding of the sliding connection assembly 102 simulates the vibration of the viscous damper to be detected.

[0036] In this embodiment, a plurality of offset blocks 104 are provided on the active rotating wheel 103, and the distance between the offset blocks 104 and the number of the offset blocks 104 are adjusted, so that the contact frequency between the offset blocks 104 and the driven rotating wheel 112 within the rotation period of the active rotating wheel 103 can be controlled, thereby realizing the periodic sliding of the sliding connection assembly 102, applying a periodic thrust to the viscous damper to be tested, and simulating the vibration to which the viscous damper to be tested is subjected during actual use.

[0037] This embodiment can specifically set the distance between the offset blocks 104, the number of the offset blocks 104, and the height of the offset blocks 104 according to different operating conditions of the viscous damper to be tested, thereby simulating different vibration conditions, thereby specifically testing the sealing of the viscous damper to be tested.

[0038] like Figure 2 and Fig. 9 As shown, the sliding connection assembly 102 is also provided with a damper movable support 113, in which a movable latch 117 is provided, and one end of the viscous damper to be detected is connected to the damper movable support 113 through the movable latch 117, and the damper fixing mechanism 200 includes a fixing seat 201 and a damper fixed support 202, and the damper fixed support 202 is arranged on the fixing seat 201, and the positions of the damper fixed support 202 and the damper movable support 113 correspond, and the other end of the viscous damper to be detected is connected to the damper fixed support 202.

[0039] In this embodiment, a damper movable support 113 is also provided on the sliding connection assembly 102 in this embodiment, and a movable latch 117 is provided in the damper movable support 113. One end of the viscous damper to be detected is connected to the damper movable support 113 through the movable latch 117. The damper fixing mechanism 200 includes a fixing seat 201 and a damper fixed support 202. The damper fixed support 202 is arranged on the fixing seat 201. The positions of the damper fixed support 202 and the damper movable support 113 correspond. The other end of the viscous damper to be detected is connected to the damper fixed support 202. The viscous damper to be detected is fixed by the damper movable support 113 and the damper fixed support 202.

[0040] When this embodiment is in use, the active wheel 103 rotates to drive the offset block 104 to squeeze the driven wheel 112, and the driven wheel 112 pushes the sliding connection assembly 102 to move. The thrust exerted on the sliding connection assembly 102 acts on one end of the viscous damper to be tested through the damper movable support 113. The other end of the viscous damper to be tested is fixed on the damper fixed support 202. The thrust at one end of the damper movable support 113 pushes the piston rod in the viscous damper to be tested to move. At this time, observe whether the viscous damper to be tested is leaking to determine its sealing performance.

[0041] In this embodiment, one end of the viscous damper to be tested is fixed, and pressure is applied to the other end to move its piston rod, thereby completing the sealing test, and the structure is more stable.

[0042] like Figure 4 and Figure 5 As shown, the rotating pushing assembly 101 also includes a hydraulic motor 106, which is arranged on the damper fixing mechanism 200. The active rotating wheel 103 is provided with an active rotating shaft 108, and the active rotating shaft 108 is connected to the output end of the hydraulic motor 106. The hydraulic motor 106 is provided with a motor oil port 111. The hydraulic motor 106 is configured to drive the active rotating wheel 103 to rotate through the active rotating shaft 108.

[0043] In this embodiment, the rotating pushing assembly 101 in this embodiment also includes a hydraulic motor 106, which is arranged on the damper fixing mechanism 200. An active rotating shaft 108 is provided on the active rotating wheel 103, and the active rotating shaft 108 is connected to the output end of the hydraulic motor 106. A motor oil port 111 is provided on the hydraulic motor 106. The hydraulic motor 106 drives the active rotating wheel 103 to rotate through the active rotating shaft 108.

[0044] When this embodiment is in use, high-pressure hydraulic oil is introduced into the hydraulic motor 106 through the motor oil port 111, and the output end of the hydraulic motor 106 drives the active shaft 108 to rotate, and the active shaft 108 further drives the active wheel 103 to rotate, and the active wheel 103 and the offset block 104 push the driven wheel 112 to achieve an extrusion test on the viscous damper to be tested.

[0045] In this embodiment, the active rotating wheel 103 is driven to rotate by the hydraulic motor 106. The rotational torque provided by the hydraulic motor 106 is relatively large, which is suitable for the detection of the viscous damper to be detected. The rotational torque acting on the sliding connection assembly 102 is sufficient to push the piston rod of the viscous damper to be detected to move, thereby ensuring the detection effect.

[0046] like Figure 7 and Figure 8 As shown, radial blind holes 107 are provided on the driving wheel 103 . The radial blind holes 107 are arranged in a circular array around the axis of the driving wheel 103 . The offset blocks 104 are arranged in the radial blind holes 107 .

[0047] In this embodiment, radial blind holes 107 are provided on the driving wheel 103 of this embodiment. The radial blind holes 107 are arranged in a circular array around the axis of the driving wheel 103. The offset blocks 104 are arranged in the radial blind holes 107. By arranging the radial blind holes 107 on the driving wheel 103 and then arranging the offset blocks 104 in the radial blind holes 107, it is ensured that the driving wheel 103 can drive the offset blocks 104 to rotate, thereby improving the force transmission effect.

[0048] When the present embodiment is in use, the offset blocks 104 are arranged in the radial blind holes 107 according to the working conditions to be simulated. For example, if the working conditions with high vibration frequency are to be simulated, the offset blocks 104 are arranged densely in the radial blind holes 107. If the working conditions with large vibration amplitude are to be simulated, the offset blocks 104 with greater height are arranged, and vice versa.

[0049] like Figure 7 and Figure 8 As shown, the rotating pushing assembly 101 further includes a fastening bolt 105 , and a bolt hole 110 is provided on the offset block 104 . The fastening bolt 105 passes through the bolt hole 110 , and the offset block 104 is bolted in the radial blind hole 107 through the fastening bolt 105 .

[0050] In this embodiment, the rotating pushing assembly 101 of this embodiment also includes a fastening bolt 105, and a bolt hole 110 is provided on the offset block 104. The fastening bolt 105 passes through the bolt hole 110, and the offset block 104 is bolted in the radial blind hole 107 through the fastening bolt 105. The fastening bolt 105 passes through the bolt hole 110 to bolt the offset block 104 in the radial blind hole 107.

[0051] When this embodiment is in use, the offset block 104 is installed by inserting the offset block 104 into the radial blind hole 107, and then the fastening bolt 105 is passed through the offset block 104 through the bolt hole 110, and then the fastening bolt 105 is bolted to the bottom of the radial blind hole 107, so that the offset block 104 can be fixed. The offset block 104 is fixed by the fastening bolt 105, and the fixing effect is more secure, which prevents the offset block 104 from falling off from the radial blind hole 107.

[0052] like Figure 6 and Fig. 9 As shown, end face flanges 109 are provided on both end faces of the driving wheel 103 , and universal ball transfers 116 are provided on both side faces of the driven wheel 112 . The universal ball transfers 116 are rotationally connected to the driven wheel 112 , and the universal ball transfers 116 are configured to roll on the end face flanges 109 .

[0053] In this embodiment, end face flanges 109 are provided on both end faces of the driving wheel 103 of this embodiment, and universal ball transfers 116 are provided on both side faces of the driven wheel 112. The universal ball transfers 116 are rotatably connected to the driven wheel 112, and the universal ball transfers 116 are configured to roll on the end face flanges 109. When the driving wheel 103 rotates, the end face flanges 109 limit the driven wheel 112 to ensure that the driven wheel 112 always corresponds to the position of the driving wheel 103 to avoid the driven wheel 112 from being offset.

[0054] When this embodiment is in use, the active rotating wheel 103 drives the end face flange 109 to rotate synchronously, and the driven rotating wheel 112 is restricted between the symmetrical end face flanges 109, so that the driven rotating wheel 112 and the active rotating wheel 103 always keep corresponding, and at the same time, a universal ball 116 is provided on the side of the driven rotating wheel 112, and the universal ball 116 rolls on the end face flange 109, reducing the friction between the end face flange 109 and the driven rotating wheel 112, so that the movement of the driven rotating wheel 112 is smoother.

[0055] like Fig. 9 and Fig.10 As shown, a compression spring 114 is provided on the sliding connection assembly 102, a spring baffle 203 is provided on the damper fixing mechanism 200, and two ends of the compression spring 114 are respectively connected to the sliding connection assembly 102 and the spring baffle 203.

[0056] In this embodiment, a compression spring 114 is provided on the sliding connection component 102 of this embodiment, and a spring baffle 203 is provided on the damper fixing mechanism 200. The two ends of the compression spring 114 are respectively connected to the sliding connection component 102 and the spring baffle 203. When the biasing block 104 contacts the driven wheel 112, the biasing block 104 pushes the sliding connection component 102 to slide on the damper fixing mechanism 200, and at the same time, the sliding connection component 102 compresses the length of the compression spring 114. When the biasing block 104 is separated from the driven wheel 112, the compression spring 114 rebounds to push the sliding connection component 102 to reset.

[0057] When this embodiment is in use, the active rotating wheel 103 drives the offset block 104 to rotate. When the offset block 104 contacts the driven rotating wheel 112, the offset block 104 pushes the sliding connection assembly 102 to slide on the damper fixing mechanism 200. The sliding connection assembly 102 pushes the piston rod of the viscous damper to be detected to move. At the same time, the sliding connection assembly 102 compresses the length of the compression spring 114. When the offset block 104 is separated from the driven rotating wheel 112, the compression spring 114 rebounds and pushes the sliding connection assembly 102 to reset. At the same time, the sliding connection assembly 102 pulls the piston rod of the viscous damper to be detected to reset. The compression spring 114 realizes the bidirectional movement of the piston rod of the viscous damper to be detected, thereby improving the detection effect of the sealing performance of the viscous damper to be detected.

[0058] like Figure 3 , Fig. 9 and Fig.10 As shown, the sliding connection component 102 is provided with a sliding groove 115 , and the damper fixing mechanism 200 is provided with a symmetrical sliding support frame 204 , and the sliding connection component 102 is slidably connected to the sliding support frame 204 through the sliding groove 115 .

[0059] In this embodiment, a sliding groove 115 is provided on the sliding connection component 102 of this embodiment, and a symmetrical sliding support frame 204 is provided on the damper fixing mechanism 200. The sliding connection component 102 is slidingly connected to the sliding support frame 204 through the sliding groove 115. When the offset block 104 pushes the driven wheel 112, the sliding connection component 102 slides on the sliding support frame 204.

[0060] When this embodiment is in use, the active rotating wheel 103 drives the offset block 104 to rotate. When the offset block 104 contacts the driven rotating wheel 112, the offset block 104 pushes the sliding connection assembly 102 to slide on the sliding support frame 204. The sliding support frame 204 provides a supporting force for the sliding connection assembly 102. At the same time, the sliding groove 115 limits the moving path of the sliding connection assembly 102, ensuring that the sliding connection assembly 102 applies thrust to the viscous damper to be detected.

[0061] like Figure 2and Fig.10 As shown, a limiting sleeve 205 is provided on the fixing seat 201 , and the limiting sleeve 205 is located between the damper fixing support 202 and the sliding connection assembly 102 , and the position of the limiting sleeve 205 corresponds to that of the damper fixing support 202 .

[0062] A limiting sleeve 205 is provided on the fixing seat 201 of the present embodiment. The limiting sleeve 205 is located between the damper fixing support 202 and the sliding connection assembly 102. The limiting sleeve 205 corresponds to the position of the damper fixing support 202. When the present embodiment is in use, the viscous damper to be tested is passed through the limiting sleeve 205, and the viscous damper to be tested is fixed by the limiting sleeve 205 to avoid its position deviation on the damper fixing mechanism 200, thereby ensuring the accuracy of the sealing test.

[0063] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
