Description

Technical Field

[0001] The present invention relates to the technical field of support and hanger performance testing, and in particular to a support and hanger performance testing device and a performance testing method. Background Art

[0002] In the power, chemical and steel industries, supports and hangers are important components to ensure the safe operation of pressure pipelines and process equipment. Their main functions are to bear loads, control displacement and suppress vibration. The size of the load is directly related to the stress and strain of the pipeline system, thus affecting the life of the pipeline system. Therefore, the mechanical quality of the supports and hangers must be tested, such as the constant force characteristics and locking overload capacity of constant force spring supports and hangers, the stiffness and locking overload capacity of variable force spring supports and hangers, the stiffness of spring shock absorbers, the damping performance of dampers, etc. Even the overload capacity of rigid supports and hangers needs to be tested item by item.

[0003] The application of online performance testing technology for supports and hangers is of great significance to improving the safety and reliability of the system. Through testing, problems with supports and hangers can be discovered in a timely manner and corresponding measures can be taken to deal with them, thereby avoiding system failures and safety accidents caused by support and hanger failures. At the same time, test data can also provide important references for the design and optimization of supports and hangers, and promote the continuous progress and development of support and hanger technology. Therefore, it is particularly important to conduct online performance testing of supports and hangers.

[0044] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0045] refer to Figure 1 , Figure 3 as well as Figure 5 It can be seen that the performance testing device of the support and hanger 3 of the present invention includes:

[0046] The test frame 1 includes a top plate 101, a bottom plate 102 and a column 103;

[0047] The slide 2 is located between the top plate 101 and the bottom plate 102. A first screw rod 104 is provided between the top plate 101 and the bottom plate 102. The first screw rod 104 is threadedly connected to the four corners of the slide 2. The first screw rod 104 can rotate relative to the top plate 101 and the bottom plate 102 to enable the slide 2 to move between the top plate 101 and the bottom plate 102.

[0048] A support bracket 3, the support bracket 3 is vertically arranged on the lower end surface of the slide seat 2;

[0049] Pipeline 4, pipeline 4 is horizontally connected to the lower end of the support bracket 3;

[0050] The force applying mechanism 5 is used to control the pipeline 4 to move downward along the Z-axis direction or horizontally along the Y-axis direction.

[0051] The rotation of the first screw rods 104 connected to the four corners of the slide 2 drives the slide 2 and the support bracket 3 connected to the lower end surface of the slide 2 to move upward, so that the support bracket 3 can be suspended in the test frame 1.

[0052] In addition, the force-applying mechanism 5 applies a driving force downward along the Z-axis direction or laterally along the Y-axis direction to the pipeline 4, driving the pipeline 4 to have a tendency to move along the Z-axis direction or along the Y-axis direction.

[0053] At this time, since the pipeline 4 is connected to the lower end of the support bracket 3, the support bracket 3 will apply a reaction force to the pipeline 4 to limit the movement of the pipeline 4, thereby transferring the driving force applied by the force-applying mechanism 5 to the pipeline 4 to the support bracket 3 to simulate the actual force condition of the support bracket 3.

[0054] Through the above technical solution, the slide 2 in the present invention suspends the support and hanger 3 in the test frame 1, and connects the pipe 4 at the lower end of the support and hanger 3 to simulate the working environment of the support and hanger 3, and drives the pipe 4 to move downward along the Z axis or horizontally along the Y axis through the force-applying mechanism 5 to simulate the actual working force condition of the support and hanger 3. Therefore, the problem of low accuracy in the detection process of the support and hanger 3 is solved.

[0055] In the present invention, the Z axis is the height direction of the test frame 1 , the Y axis is the width direction of the test frame 1 , and the X axis is the length direction of the test frame 1 .

[0056] In some embodiments, mounting grooves 105 are provided in the columns 103 on both sides of the test frame 1, and the force-applying mechanism 5 is provided in the mounting grooves 105. The force-applying mechanism 5 may include a pressure block 501, a clamp assembly and a drive assembly. The pressure block 501 is connected to both axial ends of the pipeline 4. The clamp assembly is used to clamp the pressure block 501 at the same height as the pipeline 4. The drive assembly is used to drive the clamp assembly and the pressure block 501 to move downward along the Z-axis direction or drive the pressure block 501 to move laterally along the Y-axis direction alone.

[0057] Among them, circular fixing grooves matching the shapes of the pipe openings at both ends of the pipe 4 can be set on the pressure block 501, and the two ends of the pipe 4 can be correspondingly inserted into the circular fixing grooves of the pressure blocks 501 on both sides, so that the pipe 4 moves with the pressure blocks.

[0058] In some embodiments, reference Figure 2As shown, the clamp assembly may include a support plate 502, a third slide groove 503 and a driving member 504. The pressure block 501 is arranged on the support plate 502. The third slide groove 503 is arranged on both sides of the mounting groove 105 along the Y-axis direction. The two ends of the support plate 502 can slide in the third slide groove 503. The driving member 504 is used to drive the support plate 502 to drive the pressure block 501 to move upward along the Z-axis direction, thereby lifting the force block.

[0059] The third sliding grooves 503 are vertically arranged on both sides of the mounting groove 105 along the direction of the Z axis to limit the moving direction of the support plate 502 .

[0060] In some embodiments, the driving member 504 may include a limit plate 5041, a second driving motor 5042 and a second screw rod 5043. The limit plate 5041 is slidably set in the third slide groove 503 and is located above the support plate 502. The second screw rod 5043 is connected between the limit plate 5041 and the support plate 502. The second driving motor 5042 is set on the limit plate 5041. The second screw rod 5043 is connected to the output end of the second driving motor 5042. The limit plate 5041 is detachably provided with a fastener 505 for fastening the limit plate 5041 to the column 103.

[0061] The limiting plate 5041 may be used to limit the rising height of the force block, and the fastener 505 may include a fastening bolt.

[0062] It can be understood that the tightening bolts fix the limit plate 5041 to the side of the column 103, and then the second drive motor 5042 is controlled to drive the second screw rod 5043 to rotate. At this time, the third slide groove 503 limits the support plate 502 to rotate with the second screw rod 5043, so that the support plate 502 drives the force block to move along the Z-axis direction, so that the fixed groove on the force block is level with the two end pipe openings of the pipe 4, and the two ends of the pipe 4 are inserted into the fixed grooves on both sides. At this time, the force block is clamped between the limit plate 5041 and the support plate 502.

[0063] Of course, in some other embodiments, an internally threaded sleeve 5044 can be rotatably set at one end of the limit plate 5041 toward the support plate 502, and the internally threaded sleeve 5044 is connected to the output end of the second drive motor 5042. The second screw rod 5043 is fixedly connected to the support plate 502 and threadedly connected in the internally threaded sleeve 5044. The second drive motor 5042 is controlled to drive the internally threaded sleeve 5044 to rotate, thereby driving the second screw rod 5043 to move upward along the Z-axis direction in the internally threaded sleeve 5044.

[0064] In some embodiments, the driving assembly includes a hydraulic press 506 and a variable force member 507. The output end of the hydraulic press 506 can extend into the mounting groove 105 to apply a downward driving force along the Z-axis direction to the variable force member 507. The variable force member 507 is used to transfer the driving force of the hydraulic press 506 to the pressure block 501 or to convert the driving force in the Z-axis direction into a driving force along the Y-axis direction and transfer it to the pressure block 501.

[0065] In some embodiments, reference Figure 8 and Fig. 9 It can be seen that a pressure plate 508 is provided at the output end of the hydraulic press 506, and a driving block 509 is provided at the lower end of the pressure plate 508. A first slide groove 510 and a second slide groove 511 which are layered up and down along the Z-axis direction and arranged along the X-axis direction are provided on both sides of the pressure block 501 away from the end of the pipe 4. The variable force member 507 includes a first slider 5071 slidably connected to the first slide groove 510 and a second slider 5072 slidably connected to the second slide groove 511. When the driving block 509 moves downward along the Z-axis, it contacts the top surface of the first slider 5071.

[0066] It can be understood that the force block is clamped between the first slider 5071 and the second slider 5072. After the driving block 509 contacts the top surfaces of the two first sliders 5071, the first slider 5071 transfers the pressure along the Z-axis direction applied by the driving block 509 to the force block.

[0067] In some embodiments, the first slider 5071 and the second slider facing each other are both provided with a downwardly inclined inclined surface 5073, and the driving assembly also includes a pushing member 512, which can push the two first sliders 5071 and the second slider 5072 on one side to slide in the corresponding first slide groove 510 and the second slide groove 511 at a time to avoid the driving block 509, so that the driving block 509 can contact the inclined surface 5073 of the remaining second slider 5072; of course, in some other embodiments, other corresponding structures can also be provided, and this article will not go into too much detail here.

[0068] Among them, reference Fig. 9 It can be seen that the width of the force block is smaller than the width of the mounting groove 105, and the first slide groove 510 and the second slide groove 511 extend to the outside of the support plate 502. When the first slider 5071 and the second slider 5072 slide there, there is only one second slider 5072 on the support plate 502. It can be understood that the pressure applied by the driving block 509 to the inclined surface 5073 will drive the remaining second slider 5072 to move along the Y-axis direction to the other side of the force block, thereby realizing the application of driving force in the Y-axis direction to the pipeline 4.

[0069] The pusher 512 of the present invention may have any suitable structure. Figure 6 and Figure 7 According to the embodiment, the pushing member 512 includes a fourth sliding groove 5121 , a first strip connecting plate 202 , a second strip connecting plate 202 , an L-shaped connecting plate 5122 and a second telescopic rod 5127 .

[0070] Among them, the fourth slide groove 5121 includes a horizontal groove and two straight grooves, the two straight grooves are located at the two ends of the horizontal groove and are connected to the horizontal groove, the third slider 5123 is slidably set in the horizontal groove, and the two fourth sliders 5125 are correspondingly slidably set in the two straight grooves, the two ends of the connecting plate 5122 are in contact with the third slider 5123 and the fourth slider 5125, and the second telescopic rod 5127 is set on the connecting plate 5122, which is used to push the connecting plate 5122 to slide in the fourth slide groove 5121.

[0071] The pushing member 512 further includes a first push rod 5124 for connecting the third slider 5123 and the first slider 5071 , and a second push rod 5126 for connecting the fourth slider 5125 and the second slider 5072 .

[0072] In some embodiments, a third telescopic rod 5128 is provided in the transverse groove for pushing the third slider 5123 back to its original position, and a second return spring is connected to the fourth slider 5125 and the force block for pulling the fourth slider 5125 back to its original position.

[0073] In the present invention, the support bracket 3 is subjected to a stress deformation test:

[0074] Apply force in the Z-axis direction to the support bracket 3. First, remove the fastening bolts from the limit plate 5041 so that the entire clamp assembly can move with the force block. Turn on the hydraulic press 506 to drive the pressure block 501 to descend and contact the top surface of the first slider 5071, and drive the entire clamp assembly, the force block and the pipeline 4 to move downward along the Z-axis direction, thereby applying force in the Z-axis direction to the support bracket 3 and measuring its strain.

[0075] It is worth noting that the driving force applied to the support and hanger 3 at this time includes the sum of the gravity of the clamp assembly, the force block, the pipeline 4 and the support and hanger 3 and the pressure applied by the hydraulic press 506.

[0076] To apply force in the Y-axis direction to the support bracket 3, first install the fastening bolts back on the limit plate 5041, and fix the limit plate 5041 on the column 103 to offset the gravity of the support bracket 3, the pipe 4 and the force block, so that when the force along the Y-axis direction is applied to the force block, the influence of the gravity of the support bracket 3, the pipe 4 and the force block is eliminated.

[0077] Then, the third telescopic rod 5128 on one side of the force block is driven to push the connecting plate 5122 at this end and the third slider 5123 and the fourth slider 5125 attached to the two ends of the connecting plate 5122 to move to the outside of the supporting plate 502 along the opposite direction of the X-axis, so that only the second slider 5072 remains on the supporting plate 502.

[0078] At this time, the hydraulic press 506 is turned on to drive the pressure block 501 to descend and contact the inclined surface 5073 of the second slider 5072, so as to drive the force block to move along the Y-axis direction, thereby applying force along the Y-axis direction to the support bracket 3 and measuring its strain.

[0079] In some embodiments, the slide 2 includes a connecting block 201, a strip connecting plate 202 and a fixed plate 203. The connecting block 201 is correspondingly arranged on the first screw rod 104, the strip connecting plate 202 is arranged on both sides of the fixed plate 203 and connected to the connecting block 201 located in the X-axis direction, and the support bracket 3 is connected to the lower end surface of the fixed plate 203.

[0080] In some embodiments, reference Fig.10 and Fig.11 It can be seen that a telescopic support plate 107 is provided at one end of the column 103 close to the top plate 101 for supporting the strip connecting plate 202 .

[0081] In the present invention, when the connecting block 201 and the strip connecting plate 202 are moved to corresponding positions, the control support rod is extended from the column 103 and moved to the lower end of the connecting block 201 and the strip connecting plate 202 to prevent the connection between the connecting block 201 and the strip connecting plate 202 from breaking due to gravity.

[0082] In some embodiments, reference Figure 5 It can be seen that a vibration mechanism 6 is arranged on the fixed plate 203, and the vibration mechanism 6 includes a vibration simulator 601, a vibration base 602 and a locking assembly. The vibration simulator 601 is correspondingly arranged on the vibration base 602, and the vibration base 602 is connected to the top surface of the fixed plate 203. The locking assembly is used to lock the vibration base 602 and the fixed plate 203 together. A first shock-absorbing spring is arranged between the fixed plate 203 and the two strip connecting plates 202, which is used to reduce the vibration of the vibration simulator 601 on the strip connecting plates 202.

[0083] In some embodiments, reference Fig.12 and Fig.13It can be seen that the locking assembly includes a first telescopic rod 603, a limit frame 604, a return spring and a locking rod 606. A locking groove 607 is provided on the fixed plate 203. The locking groove 607 is located on both sides of the vibration base 602 along the Y-axis direction. The limit frame 604 is arranged in the locking groove 607. The locking rod 606 is arranged in the limit frame 604. The first telescopic rod 603 is arranged on the strip connecting plate 202, and pushes the limit frame 604 to move toward the vibration base 602, so that the locking rod 606 is inserted into the vibration base 602.

[0084] Among them, blind grooves for inserting the locking rod 606 are set on both sides of the vibration base 602 in the Y-axis direction, and the width of the limit frame 604 is slightly smaller than the width of the locking groove 607, so that the limiting locking rod 606 can be accurately inserted into the blind groove.

[0085] In some embodiments, two first return springs 605 are connected to the side of the limit frame 604 facing the strip plate, which are used to pull the limit frame 604 back to its original position to release the lock on the vibration base 602 and the fixing plate 203.

[0086] In some embodiments, a plurality of second shock-absorbing springs 608 are provided on the side of the vibration base 602 facing the top plate 101, and the plurality of springs are compressed between the vibration base 602 and the top plate 101, so as to limit the vibration effect of the vibration simulator 601 on the top plate 101, and prevent the vibration base 602 from detaching from the fixing plate 203 when the vibration base 602 and the fixing plate 203 are in an unlocked state.

[0087] In the present invention, when performing a vibration test on the support and hanger 3, the first telescopic rod 603 on the strip connecting plate 202 is controlled to move toward the top limit frame 604 toward the vibration base 602, so that the locking rod 606 is inserted into the blind groove of the vibration base 602. At this time, the vibration simulator 601 is turned on, and the vibration is transmitted to the support and hanger 3 connected to its lower end surface through the fixing plate 203.

[0088] In some embodiments, a first driving motor 106 is disposed on the top surface of the test stand 1 , and an output end of the first driving motor 106 is connected to the first screw rod 104 to drive the first screw rod 104 to rotate.

[0089] In some embodiments, reference Figure 4 As shown, the strip-shaped connecting plate 202 and the connecting block 201 are plug-fitted to facilitate installation.

[0090] In some embodiments, a fixing seat is provided at the top of the support bracket 3 and is fixed to the fixing plate 203 by bolts, and a detector 301 is provided on the support bracket 3 for detecting the deformation of the support bracket 3 .

[0091] The detector 301 includes a strain sensor, the strain gauge on which will deform synchronously, and the change in the resistance of the strain gauge will cause the amount of charge in the circuit to change, thereby testing the load change trend within the travel range of the support and hanger 3.

[0092] In some embodiments, a remote client can be set to receive the test signal of the strain detector 301 and make an adjustment plan: when the vertical bearing capacity of the support bracket 3 is insufficient, additional vertical support points or reinforcements can be added; when the horizontal bearing capacity is insufficient, additional horizontal support points or reinforcements can be added; when the vibration stability is insufficient, the connection structure can be added or the material strength can be improved.

[0093] In addition, another aspect of the present invention further provides a method for testing the performance of a support and hanger 3, which uses the device for testing the performance of the support and hanger 3 as described above.

[0094] In the present invention, the support and hanger 3 is preliminarily installed first, the support and hanger 3 is connected to the bottom end of the slide 2, and then the pipeline 4 is connected to the support and hanger 3.

[0095] After completing the preliminary installation, the first drive motor 106 is controlled to drive the first screw 104 at the four corners of the slide 2 to rotate, so that the slide 2 slides upward along the Z-axis direction to place the support bracket 3 in a suspended state in the test frame 1, and then the force-applying mechanism 5 is connected to the two ends of the pipeline 4. Finally, the force-applying mechanism 5 is used to control the pipeline 4 to move downward along the Z-axis direction or horizontally along the Y-axis direction to apply a force along the Z-axis direction or a force along the Y-axis direction to the support bracket 3, and the detector 301 on the support bracket 3 is used to read the strain amount on the support bracket 3 under the two force conditions.

[0096] After the stress deformation test is completed, the vibration environment of the support and hanger 3 is simulated by the vibration mechanism 6, and the strain amount of the support and hanger 3 under the vibration condition is read out by the detector 301 on the support and hanger 3.

[0097] The preferred embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and the present invention will not further describe various possible combinations. However, these simple modifications and combinations should also be regarded as the contents disclosed by the present invention and belong to the protection scope of the present invention.
