Description

Technical Field

[0001] The invention relates to the field of MS sealant testing, and in particular to an MS sealant extreme condition simulation device and a testing method. Background Art

[0002] MS sealant is a new generation of building sealing materials. It is widely used in the fields of bonding, caulking, jointing, sealing, waterproofing and reinforcement in construction engineering and decoration. Especially in prefabricated buildings, it can effectively avoid cracking caused by large internal stress and improve durability.

[0003] When MS sealant is used in construction, the specification recommends that it should be constructed within the range of 4 to 40°C to ensure its effective bonding effect. However, due to the requirements of the project schedule, many projects have to be constructed in the winter environment of -3 to 5°C. At present, most domestic MS sealant products can basically achieve the expected bonding effect. However, in the winter environment of -10°C, the bonding effect of assembled MS sealant needs to be verified. In the northeast of my country and other regions, the outdoor temperature in winter can even reach -20°C to -30°C. Therefore, it is necessary to test the adhesion effect of MS sealant under various cold conditions; the existing test usually takes the MS sealant into the cold storage to simulate the actual situation under cold conditions, so as to test the adhesion effect of MS sealant, but this test cost is high, and at the same time, workers are often required to enter the cold storage to cooperate with the test. Workers are in the cold storage conditions for a long time, which causes damage to the workers' bodies and easily causes discomfort to the workers. Based on this, we proposed a simulation equipment and test method for the extreme conditions of MS sealant. Summary of the invention

[0004] In order to solve the technical problem that the existing MS sealant testing often requires workers to enter a cold storage to cooperate with the testing, and the workers are in the cold storage conditions for a long time, which causes damage to the workers' bodies, the present invention provides an MS sealant extreme condition simulation device and a testing method.

[0005] The present invention is implemented by the following technical scheme: a simulation device for the extreme conditions of MS sealant, comprising a simulation device as a whole, the simulation device as a whole comprising a two-way reciprocating movement mechanism; an opening and closing separation mechanism; a refrigeration simulation mechanism for simulating a freezing environment; and a cleaning mechanism for cleaning the MS sealant;

[0006] The bidirectional reciprocating mechanism includes a motor mounting plate, a moving gear is connected to the bottom of the motor mounting plate, a bidirectional rack is meshed on the outer side of the moving gear, the bidirectional rack is clamped in the limit slot block, the bottom end of the bidirectional rack is connected to a mounting rod, the mounting rod is connected to the sub-telescopic rod, and the sub-telescopic rod is inserted into the inner side of the main telescopic rod.

[0007] The opening and closing separation mechanism includes a receiving seat, which is installed on a movable plate, and the bottom end of the receiving seat is connected to a sliding rack, which is arranged in a sliding groove, and a rotating gear is arranged inside the sliding groove; an adjusting groove is opened on the surface of the movable plate, and a transverse frame is overlapped at the bottom end of the movable plate, and a limiting block extends above the transverse frame, and the limiting block is clamped in the adjusting groove in the movable plate; one end of the transverse frame is connected to a moving component part, and the moving component part slides inside the moving groove, and a fixed block is connected above the moving component part, and a closing plate is connected above the fixed block.

[0008] The refrigeration simulation mechanism includes a connecting rod, the bottom end of the connecting rod is connected to the rotating gear, the top surface of the connecting rod is sleeved with a main gear, the connecting rod passes through the mounting plate, the outer side of the main gear is meshed with an eccentric gear, the surface of the eccentric gear is mounted with a first axis, one end of the moving shaft is connected to the first axis, the other end is connected to the second axis, the second axis is mounted on the swing rod, one end of the swing rod is provided with a rotating axis, the rotating axis is connected to the rotating shaft seat, and the other end of the swing rod is connected to the refrigerator;

[0009] The cleaning mechanism includes a rotating disk, the surface of the rotating disk is connected to a first adjusting axis, one end of the adjusting shaft is connected to the first adjusting axis, the other end of the adjusting shaft is connected to the second adjusting axis, the second adjusting axis is installed on the top of the moving rod, the bottom end of the moving rod is connected to the inside of the transverse groove, the surface of the moving rod is sleeved with a connecting sleeve, the outer side of the connecting sleeve is movably connected to a cleaning rod, and the cleaning rod is connected to a cleaning brush.

[0010] As a further improvement of the above solution, the rod body of the sub-telescopic rod is inserted into the main telescopic rod, the sub-telescopic rod slides inside the rod body of the main telescopic rod, and one end of the sub-telescopic rod is connected to the receiving seat in the opening and closing separation mechanism.

[0011] As a further improvement of the above solution, four groups of closing plates are provided, and the four groups of closing plates are closed to form a circular shape. Sealing parts are provided at the connection between adjacent closing plates, and MS sealing glue is applied to the sealing parts.

[0012] As a further improvement of the above scheme, the sub-telescopic rod drives the receiving seat connected to it to move back and forth horizontally, and the two-way reciprocating movement mechanism can drive the opening and closing separation mechanisms set on both sides to move synchronously, thereby realizing the synchronous movement of the two sets of opening and closing separation mechanisms and ensuring the synchronization of the work.

[0013] As a further improvement of the above scheme, two groups of opening and closing separation mechanisms are provided, and the two groups of opening and closing separation mechanisms are arranged at both ends of the two-way reciprocating mechanism. The operation of the two-way reciprocating mechanism drives the two groups of two-way reciprocating mechanisms to move synchronously.

By observing how long it takes for the closing plates to be separated under the pulling of external force when the closing plates are sealed with MS sealant, the adhesion strength of MS sealant under different cold conditions can be known.

[0015] As a further improvement of the above scheme, the refrigerator connected to it is driven to perform reciprocating deflection and swing through the swing rod, and the refrigerator sprays out refrigerant gas to ensure uniform spraying of the cold air. The temperature of the cold air sprayed by the refrigerator can be controlled and adjusted according to actual conditions. The reciprocating swing of the refrigerator sprays the refrigerant gas, and the cold air reaches the sealing part to simulate the cold weather outside, so as to facilitate the subsequent measurement of the adhesion strength of the MS sealant in cold weather.

[0016] As a further improvement of the above solution, the excess MS sealant dripping from the sealing part is cleaned by lateral movement and swinging of the cleaning brush, thereby preventing the excess MS sealant from falling downward and avoiding adhesion of the mechanical structure.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention innovatively proposes a refrigeration simulation mechanism and a cleaning mechanism. The two groups of mechanisms are tightly connected together. When the refrigeration simulation mechanism is working, the refrigerator performs reciprocating deflection and swinging. When the refrigerator sprays out refrigerant gas, the cleaning mechanism also works synchronously. The cleaning brush in the cleaning mechanism also performs reciprocating swinging synchronously. The cleaning brush cleans the excess MS sealant dripping from the sealing part to prevent the excess MS sealant from falling to the bottom and avoiding adhesion of the mechanical structure. The two groups of mechanisms are tightly connected to ensure the synchronization of the work.

[0019] 2. The two-way reciprocating mechanism, the opening and closing separation mechanism, the refrigeration simulation mechanism and the cleaning mechanism of the present invention are interconnected. The synchronous operation of all the mechanisms can be achieved only through the operation of the motor in the motor mounting plate of the two-way reciprocating mechanism. The four groups of mechanisms are linked to each other to ensure the compactness and synchronization of the structural operation, and also save costs. By observing how long it takes for the closing plates to be separated under the pull of external force when the closing plates are sealed with MS sealant, the adhesion force of the MS sealant under different cold conditions can be known, thereby realizing the detection of the adhesion effect of the MS sealant under cold conditions.

[0033] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0034] Embodiment 1:

[0035] Please combine Figure 1-Figure 5 This embodiment proposes a simulation device for the extreme conditions of MS sealant, including a simulation device as a whole 1, the simulation device as a whole 1 including a two-way reciprocating movement mechanism 2; an opening and closing separation mechanism 3; a refrigeration simulation mechanism 4 for simulating a freezing environment; and a cleaning mechanism 5 for cleaning the MS sealant;

[0036] The bidirectional reciprocating mechanism 2 includes a motor mounting plate 21, a moving gear 22 is connected to the bottom of the motor mounting plate 21, a bidirectional rack 23 is meshed on the outer side of the moving gear 22, the bidirectional rack 23 is clamped in the limiting groove block 24, and a mounting rod 25 is connected to the bottom end of the bidirectional rack 23, the mounting rod 25 is connected to the sub-telescopic rod 26, and the sub-telescopic rod 26 is inserted into the inner side of the main telescopic rod 27.

[0037] It should be noted that the rod body of the sub-telescopic rod 26 is inserted into the main telescopic rod 27, the sub-telescopic rod 26 slides inside the rod body of the main telescopic rod 27, and one end of the sub-telescopic rod 26 is connected to the receiving seat 31 in the opening and closing separation mechanism 3.

[0038] More specifically, when the closing plates 312 are in the closed state, the staff drips MS sealant into the sealing portion 313 between the adjacent closing plates 312 and smoothes it. Then, the motor inside the motor mounting plate 21 is operated to drive the motion gear 22 connected thereto to rotate, and the motion gear 22 drives the two-way rack 23 meshing therewith to move, and the two-way rack 23 then slides on the inner side of the limit slot block 24. With the movement of the two-way rack 23, the mounting rod 25 connected to the two-way rack 23 is driven to move synchronously, and the mounting rod 25 drives the sub-telescopic rod 26 to perform telescopic operation on the inner side of the main telescopic rod 27, and the sub-telescopic rod 26 thereby drives the receiving seat 31 connected thereto to reciprocate and move horizontally, and the two-way reciprocating movement mechanism 2 can thereby drive the opening and closing separation mechanisms 3 arranged on both sides to move synchronously, thereby realizing the synchronous movement of the two sets of opening and closing separation mechanisms 3, and ensuring the synchronization of the work;

[0039] Furthermore, two groups of opening and closing separation mechanisms 3 are provided, and the two groups of opening and closing separation mechanisms 3 are arranged at both ends of the two-way reciprocating mechanism 2. The operation of the two-way reciprocating mechanism 2 drives the two groups of two-way reciprocating mechanisms 2 to move synchronously.

[0040] The opening and closing separation mechanism 3 includes a receiving seat 31, which is mounted on a movable plate 32. The bottom end of the receiving seat 31 is connected to a sliding rack 33, which is arranged in a sliding groove 34. A rotating gear 35 is arranged inside the sliding groove 34. An adjusting groove 36 is provided on the surface of the movable plate 32. A transverse frame 37 is overlapped at the bottom end of the movable plate 32. A limiting block 38 extends above the transverse frame 37. The limiting block 38 is clamped in the adjusting groove 36 in the movable plate 32.

[0041] One end of the transverse frame 37 is connected to a moving assembly part 39 , and the moving assembly part 39 slides inside the moving groove 310 . A fixing block 311 is connected above the moving assembly part 39 , and a closing plate 312 is connected above the fixing block 311 .

[0043] More specifically, while the receiving seat 31 is driven by the telescopic rod 26 to move, the receiving seat 31 synchronously drives the movable plate 32 connected thereto to move. As the movable plate 32 moves laterally, the adjustment groove 36 on the surface of the movable plate 32 drives the limit block 38 to move synchronously. The limit block 38 thereby drives the transverse movement frame 37 thereunder to move. The transverse movement frame 37 thereby drives the moving component part 39 to slide on the inner side of the moving groove 310. The moving component part 39 thereby pulls the fixed block 311 connected thereto to move synchronously. The fixed block 311 thereby drives the closing plate 312 to move, pulling the closing plates 312 to separate. By observing how long it takes for the closing plates 312 to be separated under the pull of external force when the closing plates 312 are sealed with MS sealant, the adhesion force of the MS sealant under different cold conditions can be known.

[0044] Embodiment 2:

[0045] Please combine Figure 6-Figure 8 Embodiment 2 further proposes a refrigeration simulation mechanism 4 and a cleaning mechanism 5. The refrigeration simulation mechanism 4 and the cleaning mechanism 5 are each provided with two groups, which are symmetrically installed at both ends of the simulation device as a whole 1.

[0046] The refrigeration simulation mechanism 4 includes a connecting rod 41, the bottom end of the connecting rod 41 is connected to the rotating gear 35, the top surface of the connecting rod 41 is sleeved with a main gear 43, the connecting rod 41 passes through the mounting plate 42, the outer side of the main gear 43 is meshed with an eccentric gear 44, the surface of the eccentric gear 44 is mounted with a first axis 45, one end of a moving shaft 46 is connected to the first axis 45, the other end is connected to a second axis 47, the second axis 47 is mounted on a swing rod 48, one end of the swing rod 48 is provided with a rotating axis 49, the rotating axis 49 is connected to a rotating shaft seat 410, and the other end of the swing rod 48 is connected to a refrigerator 411;

[0047] More specifically, when the receiving seat 31 is driven by the telescopic rod 26, the receiving seat 31 then drives the sliding rack 33 connected to the bottom end thereof to slide inside the sliding groove 34. As the sliding rack 33 slides, the rotating gear 35 meshing therewith is then driven to rotate, and the connecting rod 41 connected to the top of the rotating gear 35 is then driven to rotate synchronously, and the main gear 43 sleeved on the rod body surface at the top of the connecting rod 41 is driven to rotate synchronously;

[0048] As the main gear 43 rotates, the main gear 43 then drives the two sets of eccentric gears 44 meshing therewith to rotate synchronously, the first axis 45 connected to the surface of the eccentric gear 44 is driven to reciprocate, the motion shaft 46 connected to the outside of the first axis 45 is driven to move synchronously, the second axis 47 connected to the other end of the motion shaft 46 is driven to move synchronously, the second axis 47 then drives the swing rod 48 connected thereto to swing back and forth, the rotating axis 49 at the bottom end of the swing rod 48 deflects with the rotating shaft seat 410 as the base point, and the swing rod 48 thereby drives the refrigerator 411 connected thereto to swing back and forth, the refrigerator 411 sprays refrigerant gas to ensure uniform spraying of the cold air, the temperature of the cold air sprayed by the refrigerator 411 can be controlled and adjusted according to actual conditions, the reciprocating swing of the refrigerator 411 to spray the refrigerant gas, the cold air reaches the sealing part 313, simulating the cold weather outside, so as to facilitate the subsequent measurement of the adhesion force of the MS sealant in cold weather.

[0049] It should be noted that the top end of the connecting rod 41 is connected to the rotating disk 51 in the cleaning mechanism 5, and the connecting rod 41 rotates while driving the rotating disk 51 to rotate synchronously.

[0050] The cleaning mechanism 5 includes a rotating disk 51, the surface of which is connected to a first adjusting axis 52, one end of an adjusting shaft 53 is connected to the first adjusting axis 52, the other end of the adjusting shaft 53 is connected to a second adjusting axis 54, the second adjusting axis 54 is installed at the top of a moving rod 55, the bottom end of the moving rod 55 is connected to the inside of a transverse groove 56, a connecting sleeve 57 is sleeved on the surface of the moving rod 55, a cleaning rod 58 is movably connected to the outer side of the connecting sleeve 57, and a cleaning brush 59 is connected to the cleaning rod 58.

[0051] Specifically, with the rotation of the connecting rod 41, the rotating disk 51 connected to the top of the connecting rod 41 rotates synchronously, and the first adjusting axis 52 connected to the surface of the rotating disk 51 moves synchronously. The first adjusting axis 52 then drives the adjusting shaft 53 to swing synchronously, and the adjusting shaft 53 thereby drives the second adjusting shaft 54 ​​connected thereto to move synchronously. The moving rod 55 connected below the second adjusting shaft 54 ​​is then driven to slide inside the transverse groove 56, and the moving rod 55 thereby performs reciprocating transverse movement. With the reciprocating transverse movement of the moving rod 55, the connecting sleeve 57 and the cleaning rod 58 connected thereto are driven to move, and the cleaning rod 58 thereby drives the cleaning brush 59 connected thereto to perform reciprocating transverse movement and swing. With the transverse movement and swing of the cleaning brush 59, the excess MS sealant dripping from the sealing portion 313 is cleaned to prevent the excess MS sealant from falling to the bottom, thereby avoiding adhesion of the mechanical structure.

[0052] The specific implementation steps of the overall technical solution of the present invention are as follows:

[0053] When in use, when the closing plates 312 are in the closed state, the staff drips MS sealant into the sealing portion 313 between the adjacent closing plates 312 and smoothes it. Then, the motor inside the motor mounting plate 21 is operated to drive the motion gear 22 connected thereto to rotate, and the motion gear 22 drives the two-way rack 23 meshing therewith to move, and the two-way rack 23 then slides on the inner side of the limit slot block 24. With the movement of the two-way rack 23, the mounting rod 25 connected to the two-way rack 23 is driven to move synchronously, and the mounting rod 25 drives the sub-telescopic rod 26 to perform telescopic operation on the inner side of the main telescopic rod 27, and the sub-telescopic rod 26 thereby drives the receiving seat 31 connected thereto to move back and forth, and the two-way reciprocating movement mechanism 2 can thereby drive the opening and closing separation mechanisms 3 arranged on both sides to move synchronously, thereby realizing the synchronous movement of the two sets of opening and closing separation mechanisms 3, and ensuring the synchronization of the work;

[0054] When the receiving seat 31 is driven by the telescopic rod 26, the receiving seat 31 then drives the sliding rack 33 connected to its bottom end to slide inside the sliding groove 34. As the sliding rack 33 slides, it drives the rotating gear 35 meshing with it to rotate, and the connecting rod 41 connected to the top of the rotating gear 35 is then driven to rotate synchronously, and the main gear 43 sleeved on the surface of the rod body at the top of the connecting rod 41 is driven to rotate synchronously. As the main gear 43 rotates, the main gear 43 then drives the two sets of eccentric gears 44 meshing with it to rotate synchronously, and the first axis 45 connected to the surface of the eccentric gear 44 is driven to reciprocate, and the motion shaft 46 connected to the outside of the first axis 45 is driven to rotate. The second axis 47 connected to the other end of the motion shaft 46 is driven to move synchronously, and the second axis 47 then drives the swing rod 48 connected thereto to swing back and forth, and the rotating axis 49 at the bottom of the swing rod 48 deflects with the rotating shaft seat 410 as the base point, and the swing rod 48 drives the refrigerator 411 connected thereto to swing back and forth, and the refrigerator 411 sprays refrigerant gas to ensure uniform spraying of the cold air. The temperature of the cold air sprayed by the refrigerator 411 can be controlled and adjusted according to actual conditions. The reciprocating swing of the refrigerator 411 sprays the refrigerant gas, and the cold air reaches the sealing part 313 to simulate the cold weather outside, so as to facilitate the subsequent measurement of the adhesion force of the MS sealant in cold weather.

[0055] With the rotation of the connecting rod 41, the rotating disk 51 connected to the top of the connecting rod 41 rotates synchronously, and the first adjusting axis 52 connected to the surface of the rotating disk 51 moves synchronously. The first adjusting axis 52 then drives the adjusting shaft 53 to swing synchronously, and the adjusting shaft 53 drives the second adjusting shaft 54 ​​connected thereto to move synchronously. The moving rod 55 connected below the second adjusting shaft 54 ​​is then driven to slide inside the transverse groove 56, and the moving rod 55 moves back and forth transversely. With the reciprocating transverse movement of the moving rod 55, the connecting sleeve 57 and the cleaning rod 58 connected thereto are driven to move, and the cleaning rod 58 drives the cleaning brush 59 connected thereto to move back and forth transversely and swing. With the transverse movement and swing of the cleaning brush 59, the excess MS sealant dripping from the sealing portion 313 is cleaned to prevent the excess MS sealant from falling to the bottom, thereby avoiding adhesion of the mechanical structure.

[0056] At the same time, while the receiving seat 31 is driven by the telescopic rod 26 to move, the receiving seat 31 synchronously drives the movable plate 32 connected thereto to move. As the movable plate 32 moves laterally, the adjustment groove 36 on the surface of the movable plate 32 drives the limit block 38 to move synchronously. The limit block 38 thereby drives the transverse movement frame 37 below it to move. The transverse movement frame 37 thereby drives the moving component part 39 to slide on the inner side of the moving groove 310. The moving component part 39 thereby pulls the fixed block 311 connected above it to move synchronously. The fixed block 311 thereby drives the closing plate 312 to move and pulls the closing plate 312 to separate. By observing how long it takes for the closing plate 312 to be separated under the pull of external force when the closing plate 312 is sealed with MS sealant, the adhesion force of the MS sealant under different cold conditions can be known.

[0057] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
