Description

Technical Field

[0001] The invention belongs to the technical field of damper testing, and in particular relates to a bidirectional testing device for a rollover damper. Background Art

[0002] A damper is a device that provides resistance to movement and dissipates the energy of movement. Various dampers (or shock absorbers) have long been used in aerospace, aviation, military, guns, automobiles and other industries to reduce vibration and dissipate energy. At present, high-frequency heavy-duty hydraulic dampers are widely used in the field of nuclear power engineering, mainly for vibration reduction and isolation of large pipelines, in order to reduce or even avoid pipeline damage caused by vibrations caused by geological activities, mechanical vibrations and other factors.

[0003] Some dampers work in a horizontal direction, while others in a vertical direction. However, independent test platforms are used to test horizontal dampers and vertical dampers. For example, a horizontal damper is tested in a horizontal direction using a horizontal test platform, while a vertical damper is tested in a vertical direction using a vertical test platform. This means that at least two test platforms are required, which undoubtedly increases the equipment investment cost and floor space. Therefore, it is necessary to design a damper test device that can be used for both horizontal and vertical tests. Summary of the invention

[0063] Optionally, in this embodiment, the turning frame 2 may be a frame body surrounded by a turning seat 21, a mounting plate 22 and two side frames 23; and the vibration excitation device 211 may be a hydraulic vibration exciter.

[0064] In this embodiment, when the lateral damper 100 needs to be tested, the flip frame 2 can be flipped to the position as shown in FIG. Figure 1 The two ends of the lateral damper 100 are then connected to the excitation device 211 and the pressure sensor 221 respectively through the two quick release devices 4 for testing; when the vertical damper 200 needs to be tested, the flip frame 2 can be flipped to the horizontal position as shown by the flip drive device 3. Figure 2 and Figure 3 The vertical damper 200 is in the vertical position shown, and then the upper end and the lower end of the vertical damper 200 are connected to the pressure sensor 221 and the vibration excitation device 211 respectively through the vertical fixing device 5 for testing.

[0065] See also Figures 1 to 3In order to fix the flip frame 2 when the flip frame 2 is flipped to a vertical position, optionally, a plurality of first plug-in ears 212 are provided on the side of the flip seat 21, and a first plug-in hole 2121 is provided in each first plug-in ear 212; a first U-shaped groove 11 is provided on the fixed seat 1 for inserting the corresponding first plug-in ear 212; a first locking cylinder 12 is provided on one side of the first U-shaped groove 11, which is used for inserting its piston rod into the first plug-in hole 2121 after the first plug-in ear 212 is inserted into the first U-shaped groove 11, so as to connect the first plug-in ear 212 with the fixed seat 1.

[0066] See also Figures 1 to 3 In order to fix the flip frame 2 when the flip frame 2 is flipped to the horizontal position, optionally, a second plug-in ear 222 is provided on the side of the mounting plate 22, and a second plug-in hole 2221 is provided in each second plug-in ear 222; the flip damper bidirectional testing device also includes a support seat 6; the support seat 6 is provided with a second U-shaped groove 61 for inserting the corresponding second plug-in ear 222; a second locking cylinder 62 is provided on one side of the second U-shaped groove 61, which is used for inserting its piston rod into the second plug-in hole 2221 after the second plug-in ear 222 is inserted into the second U-shaped groove 61, so as to connect the second plug-in ear 222 with the support seat 6.

[0067] In some prior arts, the lug 101 of the lateral damper 100 is generally fixed by passing a pin through the fixing seat and the lug 101, and then inserting pins at both ends of the pin, and finally inserting a washer of corresponding thickness between the lug 101 and the pin. This method requires plugging and pulling out the pin, plugging and pulling out the plug, and plugging and pulling out the washer during disassembly and assembly. Generally, a high-frequency heavy-load hydraulic damper weighs 1.5 tons. For such a large damper, the above manual operation process is relatively complicated, and the disassembly and assembly are difficult, and there are safety hazards. In addition, the lug apertures of different models of dampers are different in size. Therefore, in order to make the pin and the lug fit tightly, it is necessary to prepare multiple pins and washers with matching diameters in advance, which is costly.

[0068] See also Figures 4 to 8As a preferred embodiment of the quick release device 4, the quick release device 4 comprises: a block 41, one end of which is provided with a connection block 411 for connecting with the excitation device 211 or the pressure sensor 221, and the other end is provided with two opposite mounting blocks 412; a through hole 413 is provided in the mounting block 412, and a baffle 414 is fixed on the outer side of the mounting block 412; two pins 42 are respectively provided in the corresponding through holes 413, and one end of the pin 42 extends out from the through hole 413, and the other end passes through The spring 43 is connected to the baffle 414; when the pull ear 101 of the lateral damper 100 is inserted between the two mounting blocks 412, the inner ends of the two pins 42 are abutted against each other to be inserted into the pull ear hole 102 to fix the pull ear 101; two groups of sleeves 44 are respectively arranged between the outer wall of the pin 42 and the inner wall of the through hole 413; each group of sleeves 44 includes multiple layers of coaxial sleeves 44, which are used to select a corresponding number of sleeves 44 to seal the gap according to the size of the gap between the outer wall of the pin 42 and the pull ear hole 102.

[0069] Preferably, the upper and lower surfaces of the inner ends of the pin shafts 42 are provided with inclined surfaces 421 , so that when the inner ends of the two pin shafts 42 abut against each other, two upper and lower V-shaped notches are formed, which can facilitate the pull ear 101 to push the two pin shafts 42 apart.

[0070] In this embodiment, the pin shaft 42 of the quick release device 4 is of plug-free design, the plug-in and pull-out operation of the sleeve 44 is simple and convenient, and by setting multiple layers of sleeves 44 for selection, gaps of different thicknesses can be flexibly matched.

[0071] Furthermore, the quick-release device 4 also includes a sleeve moving assembly installed on the corresponding mounting block 412; the sleeve moving assembly includes a plurality of moving rings 45, which are arranged on the outer side of the baffle 414 in a one-to-one correspondence with each sleeve 44; each moving ring 45 is connected to the corresponding sleeve 44 through a plurality of connecting rods 46.

[0072] Optionally, each movable ring 45 is connected to the corresponding sleeve 44 via a plurality of connecting rods 46 , and the connecting rods 46 may be arranged in a ring shape on the circumference.

[0073] In some application scenarios, for example, the thickness of each layer of sleeve 44 can be 5 mm, and there can be 10 layers. If the thickness of the gap between the outer wall of the pin shaft 42 and the pull ear hole 102 is 20 mm, the 4-layer sleeve 44 located on the inner side can be selected and pushed into the gap through the corresponding moving ring 45, so that the pin shaft 42 and the pull ear 101 are tightly matched. Of course, in some other embodiments, the thickness of each layer of sleeve 44 can be other values.

[0074] Furthermore, a plurality of threaded holes 4141 are provided on the outer surface of the baffle 414; a plurality of fixing members 47 for adapting to the threaded holes 4141 are provided on the movable ring 45; wherein when the movable ring 45 drives the sleeve 44 to be inserted into the gap between the outer wall of the pin shaft 42 and the pull ear hole 102, the fixing member 47 is screwed into the corresponding threaded hole 4141 to fix the movable ring 45 and the baffle 414 together.

[0075] Optionally, the fixing member 47 and the movable ring 45 may also be threadedly matched, and may always remain on the movable ring 45 .

[0076] It should be noted that the length of the sleeve 44 is such that after being inserted into the gap, a certain length of the sleeve 44 is still located in the through hole 413 .

[0077] During specific installation, when fixing the pull ear 101 of the lateral damper 100, the pull ear 101 can be inserted from top to bottom between the two mounting blocks 412. After the lower end of the pull ear 101 contacts the V-shaped notch on the upper side of the pin 42, the two pins 42 will overcome the elastic force of the spring 43 and retreat until the pin 42 is inserted into the pull ear hole 102; then, several layers of sleeves 44 are selected according to the thickness of the gap between the outer wall of the pin 42 and the pull ear hole 102, and the corresponding sleeves 44 are inserted into the gap by pushing the corresponding moving rings 45, and then the fixings 47 on these moving rings 45 are screwed into the corresponding threaded holes 4141, so that the moving rings 45 are fixed on the baffle 414, so that the pin 42, the pull ear 101, the sleeve 44, and the mounting block 412 are tightly matched, and loosening due to vibration can be prevented.

[0078] In some application scenarios, since the high-frequency heavy-load hydraulic damper is heavy, manual pushing of the moving ring 45 has certain safety hazards. Therefore, automatic pushing can be achieved through the moving ring driving mechanism 48.

[0079] See also Figure 1 , Figure 4 , Figure 5 , Fig. 9, the quick release device 4 also includes a moving ring driving mechanism 48, which is used to drive the moving ring 45 to move; the moving ring driving mechanism 48 includes: a push rod motor 481, whose fixed end is installed on the side frame 23 of the flip frame 2; a box body 482, fixed to the driving end of the push rod motor 481, and the box body 482 is connected to the side frame 23 of the flip frame 2 through a plurality of telescopic guide columns 483; a rotating motor 484, installed in the box body 482; a plurality of connecting rod assemblies, each connecting rod assembly includes a first connecting rod 485 and a second connecting rod 486; the inner end of the first connecting rod 485 is rotatably installed in the box body 482, and cooperates with the output shaft gear of the rotating motor 484; the outer end of the first connecting rod 485 is hinged to the inner end of the second connecting rod 486; the outer end of the second connecting rod 486 extends out of the box body 482 from the guide hole 4821 on the side wall of the box body 482, and a push-pull column 487 is provided on the outer end.

[0080] Specifically, when the rotary motor 484 rotates, it can drive the first connecting rod 485 to move, the first connecting rod 485 drives the second connecting rod 486 to move, and the second connecting rod 486 can drive the push-pull column 487 to move closer to or away from the box body 482. In other words, by rotating the rotary motor 484, multiple push-pull columns 487 can be located on circumferences of different diameters, so that corresponding moving rings 45 located on different circumferences can be pushed.

[0081] For example, when the four-layer sleeve 44 located in the inner circle needs to be inserted into the gap, the rotating motor 484 drives the push-pull column 487 to be located on the circumference of the first layer of sleeve 44, and the push rod motor 481 is actuated to drive the push-pull column 487 to push the movable ring 45 corresponding to the first layer of sleeve 44, thereby pushing the first layer of sleeve 44 into the gap, and then the push rod motor 481 drives the push-pull column 487 to retract, and the rotating motor 484 drives the push-pull column 487 to be located on the circumference of the second layer of sleeve 44, and so on, inserting the sleeves 44 into the gap one by one.

[0082] Furthermore, in order to automatically pull out the sleeve 44 , preferably, the end surface of the push-pull column 487 is provided with a plug-in groove 4871 adapted to the fixing member 47 .

[0083] In this embodiment, the insertion groove 4871 can be used for inserting the fixing member 47 on the moving ring 45, and the inner wall of the insertion groove 4871 can be provided with an elastic member so as to have an interference fit with the fixing member 47. After the fixing member 47 is screwed out from the baffle 414, the fixing member 47 is still connected to the moving ring 45, and the push-pull column 487 can be driven by the push rod motor 481 to cover the fixing member 47, and then retract to drive the moving ring 45 to pull out the corresponding sleeve 44.

[0084] Optionally, since the push-pull column 487 does not move in a straight line in the radial direction but moves in an arc, the installation position of the fixing part 47 on each movable ring 45 can be determined according to the position of the push-pull column 487 on different circumferences, thereby ensuring that the push-pull column 487 can be adapted to the position of the fixing part 47 on the circumference when it is on different circumferences.

[0085] For example, when it is necessary to pull out a sleeve 44 of a certain layer, the rotating motor 484 drives the push-pull column 487 to the circumference where the sleeve 44 is located, the push rod motor 481 is actuated, and the push-pull column 487 is sleeved on the fixing part 47 on the movable ring 45 of that layer, and the push rod motor 481 retracts to pull out the sleeve 44 of that layer.

[0086] See also Figure 2 , Figure 3 and Fig.10 The vertical fixing device 5 includes: a top rod 51, whose upper end is connected to the pressure sensor 221, and whose lower end is provided with a pressure plate 52 for pressing on the vertical damper 200; a damper mounting plate 53, whose lower end is fixedly connected to the excitation device 211, and whose upper end surface is provided with a plurality of strip grooves 531 distributed in an x ​​shape; the four corners of the vertical damper 200 are fixed in the strip grooves 531 by bolts.

[0087] In this embodiment, when testing the vertical damper 200, the four corners of the bottom plate of the vertical damper 200 are fixed in the corresponding strip grooves 531 by corresponding bolts, and then the piston rod of the excitation device 211 is pushed out, and the upper end of the vertical damper 200 is pressed tightly against the pressure plate 52 to perform the test. The strip grooves 531 distributed in an x-shape can adapt to the installation of vertical dampers 200 of different sizes.
