Description

Technical Field

[0001] The invention relates to the technical field of building material waterproof detection, in particular to building material waterproof detection equipment. Background Art

[0002] Building materials are various materials used in construction projects. There are many types of building materials, which can be roughly divided into: inorganic materials, organic materials and composite materials. With the continuous development of construction technology and the continuous innovation of the combination components and combination technology of building materials, as well as the increasing demand of users for building materials and the improvement of quality, the waterproofness of building materials has received more and more attention.

[0003] The anti-penetration test is one of the important indicators for testing the waterproof performance of building materials. Common testing methods include pressure test, loss test and immersion test. When conducting the anti-penetration test, the soaked building materials are generally weighed, and the change in weight before and after immersion is observed to judge the waterproof performance of the building materials.

[0004] In the prior art, the announcement number is CN116297108B, and the main title is a waterproof detection system and detection method for building material production. The patent proposes that the soaked building materials are transported to the support plate, and when the support plate is supported by the reset spring, the changes of the reset spring and the support plate are observed. When the support plate moves downward under the influence of the building material, it can be judged that the waterproof performance of the material is unqualified;

[0005] However, there are still some problems in this patent. For example, it is difficult to ensure that the moisture on the surface of the building materials is completely removed when transporting building materials that have been soaked in water. For example, after soaking, some moisture will remain on the surface of building materials containing open holes, building materials containing patterns, or building materials with uneven surfaces. After the building materials are transported to the support plate, the moisture on the surface of the building materials that has not been removed will follow the building materials to exert pressure on the reset spring, thereby affecting the accuracy of the waterproof detection.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The building material waterproof testing equipment places the standard test piece on the top of the weighing scale, and then starts the electric telescopic rod through the controller. The electric telescopic rod drives the offset bracket, the fixed plate and the sleeve plate to contact the standard test piece, and then drives the standard test piece to rise in the direction of the waist bracket.

During the falling process of the standard test piece, the standard test piece contacts with two groups of water-absorbing sponges in turn, and under the short-term obstruction of the water-absorbing sponges, the standard test piece falls in an inclined state. This process improves the effect of draining water on the surface of the standard test piece, and at the same time, the water on the side of the standard test piece is absorbed and wiped by the water-absorbing sponge.

[0039] A reserved groove 37 is provided inside the vertical parts on both sides of the limit frame 33, and sliding grooves 38 are provided on both sides of the reserved groove 37. The sliding groove 38 is slidably sleeved with a sliding rod 5 inside; a rotating plate 51 is fixed outside the sliding rod 5, and a limiting block 52 is fixed on the top of the rotating plate 51. A first spring 53 is fixed outside the rotating plate 51 close to the sliding rod 5, and the first spring 53 is fixed to the inner wall of the reserved groove 37. A supporting block 54 is fixed outside the rotating plate 51 away from the first spring 53, and a water-absorbing sponge 55 is rotatably sleeved outside the two sides of the supporting block 54;

[0040] The top support assembly includes an electric telescopic rod 8, which is controlled by a controller. A dislocation bracket 81 is fixed to the outside of the output end of the electric telescopic rod 8, a fixed plate 82 is fixed to the top of one side of the dislocation bracket 81, a sleeve plate 83 is slidably sleeved on the outside of the fixed plate 82, a transverse plate 84 is fixed to the outside of the sleeve plate 83, a second spring 85 is fixed to the bottom of the transverse plate 84, and one end of the second spring 85 is fixed to the horizontal part of the dislocation bracket 81; a limiting plate 35 is fixed to the bottom of the first limiting rod 34, the limiting plate 35 is inclined, the bottom of the second limiting rod 36 is inclined, and the length of the second limiting rod 36 is 3-5cm longer than the length of the first limiting rod 34; a wiper plate 44 is slidably sleeved on the inside of the lifting groove 42, and a soft brush 43 is slidably sleeved on the wiper plate 44, a slide groove 45 is provided on one end of the movable plate 41 close to the second limiting rod 36, a locking bolt 46 is fixed to the outside of the wiper plate 44, and the locking bolt 46 is slidably sleeved inside the slide groove 45;

[0041] During the specific operation, the standard test piece 23 to be tested is first placed on the top of the measuring scale 21, and then the first servo motor 11 is controlled by the controller to start, so that the first servo motor 11 drives the linkage rod 3 to rotate, and the bottom bracket 31, the waist bracket 32 ​​and the limit bracket 33 are driven to rotate synchronously through the rotation of the linkage rod 3. When the limit bracket 33 rotates to the top of the measuring scale 21, the movable plate 41 slides inside the limit frame 4 under the influence of gravity, and the electric telescopic rod 8 is controlled by the controller to start. The electric telescopic rod 8 drives the dislocation bracket 81 and the fixed plate 82 and the sleeve plate 83 to be ejected in the direction of the waist bracket 32 ​​and contact with the standard test piece 23, so that the sleeve plate 83 and the dislocation bracket 81 drive the standard test piece 23 to move in the direction of the waist bracket 32 ​​and enter the interior of the limit bracket 33;

[0042] When the standard test piece 23 enters the interior of the limit bracket 33, it contacts the water-absorbing sponge 55 in the reserved groove 37, and squeezes the water-absorbing sponge 55 to drive the rotating plate 51 to move in the sliding groove 38, so that the water-absorbing sponge 55 is completely retracted into the interior of the reserved groove 37, and then the surface of the standard test piece 23 contacts the second limit rod 36 first, and at this time the electric telescopic rod 8 controls the standard test piece 23 to continue to be ejected, and under the limiting action of the second limit rod 36, the standard test piece 23 reversely presses the sleeve plate 83, and the sleeve plate 83 presses the second spring 85, so that the sleeve plate 83 contracts toward the measuring scale 21, until the surface of the standard test piece 23 contacts the first limit rod 34, and the standard test piece 23 is tilted along the width direction of the standard test piece 23 as a whole, and the surface of the standard test piece 23 contacts the soft brush 43, in this process, the standard test piece 23 is clamped by the offset bracket 81 and the sleeve plate 83 and the first limit rod 34 and the second limit rod 36, so as to ensure the stability of the standard test piece 23 flipping;

[0043] Furthermore, when the standard test piece 23 is turned over, the standard test piece 23 has an inclined angle, and under the influence of gravity, the water in the lines on the surface width direction of the standard test piece 23 slides downward. At the same time, the first servo motor 11 is started, and the linkage rod 3 is controlled to rotate by the first servo motor 11. The linkage rod 3 drives the bottom bracket 31, the waist bracket 32 ​​and the limit bracket 33 to rotate, and drives the standard test piece 23 inside the limit bracket 33 to rotate synchronously. In the process of tilting and turning over the standard test piece 23, the water is affected by the dual influence of gravity and the centrifugal force of the turning over, which accelerates the drainage speed of the standard test piece 23.

[0044] During the turning over of the standard test piece 23, as the standard test piece 23 gradually approaches the bottom of the inner cavity of the box body 1, the movable plate 41 gradually slides toward the side away from the standard test piece 23 under the influence of gravity. During the sliding process of the movable plate 41 in the return stroke, the soft brush 43 is driven to slide on the surface of the standard test piece 23, and the moisture in the surface texture of the standard test piece 23 is scraped off by the soft brush 43, thereby reducing the moisture contained in the surface texture of the standard test piece 23 and improving the accuracy of the later waterproof detection of the standard test piece 23;

[0045] When the standard test piece 23 is in the process of flipping, the limit frame 33 gradually approaches the support frame 2 until the limit frame 33 contacts the bottom of the support frame 2, and the controller controls the first servo motor 11 to reverse, so that the first servo motor 11 drives the linkage rod 3 to flip in the opposite direction, and the linkage rod 3 drives the bottom bracket 31, the waist bracket 32 ​​and the limit frame 33 to flip in the opposite direction, and the limit frame 33 drives the standard test piece 23 to flip in the opposite direction, and in the process of reverse flipping, the standard test piece 23 again experiences the dual effects of gravity and flipping centrifugal force, which accelerates the drainage, and at the same time, the movable plate 41 slides again from the inside of the limit frame 4 toward the standard test piece 23, and in the process of sliding, the surface of the standard test piece 23 is scraped in the opposite direction to remove water, thereby improving the accuracy of the later waterproof detection of the standard test piece 23;

[0046] Furthermore, when the limit frame 33 drives the standard test piece 23 to flip over to the top of the measuring scale 21, the controller controls the electric telescopic rod 8 to return. During the return process, the electric telescopic rod 8 releases the pressure on the standard test piece 23, so that the standard test piece 23 is carried on the top of the sleeve plate 83 and the offset bracket 81, and falls toward the measuring scale 21. During the falling process, it gradually returns to a horizontal state. At the same time, during the process of the standard test piece 23 following the offset bracket 81 and the sleeve plate 83 falling, one end of the standard test piece 23 is close to the first The water-absorbing sponge 55 on one side of the limit rod 34 is in contact with the water-absorbing sponge 55, and is subject to the resistance of the water-absorbing sponge 55 and the rotating plate 51, so that the end of the standard test piece 23 that is not in contact with the water-absorbing sponge 55 continues to move downward, while the descending speed of the end in contact with the water-absorbing sponge 55 is slowed down, thereby making the standard test piece 23 inclined along the length direction of the standard test piece 23. In this inclined state, the water contained in the lines on the length direction of the surface of the standard test piece 23 is drained out under the influence of gravity, thereby improving the drainage effect of the standard test piece 23 and the accuracy of the subsequent waterproof detection;

[0047] Then, under the influence of gravity, the standard test piece 23 squeezes the water-absorbing sponge 55. During the squeezing process, the water-absorbing sponge 55 drives the rotating plate 51 to flip in the direction of the axis of the slide rod 5 toward the weighing scale 21, and in the flipping process, the water-absorbing sponge 55 contacts the side of the standard test piece 23 and absorbs and removes the moisture in the side lines, thereby improving the drainage effect of the side lines of the standard test piece 23, until the standard test piece 23 is completely separated from the water-absorbing sponge 55 on the side close to the first limit rod 34, the water-absorbing sponge 55 and the rotating plate 51 are reset under the pulling force of the first spring 53, and the standard test piece 23 continues to fall after returning to a horizontal state. , one end of the standard test piece 23 contacts the water-absorbing sponge 55 on the side away from the first limit rod 34 again. Due to the upper and lower offset settings of the two sets of reserved grooves 37 and the water-absorbing sponge 55, the standard test piece 23 tilts again, and this time the tilting direction is opposite to the above tilting direction. Therefore, during the falling process, the standard test piece 23 tilts relatively twice along the length direction of the standard test piece 23, so that both side edges of the standard test piece 23 are able to contact the water-absorbing sponge 55 and are drained by the water-absorbing sponge 55. At the same time, the water contained in the length direction of the lines on the surface of the standard test piece 23 is drained, thereby improving the accuracy of the later waterproof detection of the standard test piece 23.

[0048] It should be noted that when the surface of the standard test piece 23 to be tested has uneven textures of different depths, the locking bolt 46 and the movable plate 41 can be activated by rotating the nut outside the locking bolt 46, and the locking bolt 46 can be adjusted to drive the wiper plate 44 to adjust the depth inside the lifting groove 42 through the locking bolt 46, so as to avoid increasing the sliding resistance of the movable plate 41 and the actual effect of the soft brush 43 wiping water when the wiper plate 44 contacts the uneven standard test piece 23. When in a smooth state, the depth of the wiper blade 44 can be adjusted so that the bottom of the wiper blade 44 is flush with the bottom of the soft brush 43, that is, the wiper blade 44 directly contacts the surface of the standard test piece 23, and during the sliding process, the wiper blade 44 directly performs a wiping operation, that is, the wiper blade 44 is suitable for wiping operations on standard test pieces 23 with smooth surfaces, and the soft brush 43 is suitable for wiping operations on standard test pieces 23 with uneven surfaces, thereby improving the drainage effect of the present invention on standard test pieces 23 with different degrees of surface roughness.

[0049] Embodiment 2:

[0050] A double-layer drain trough 6 is provided on one side of the two bottom brackets 31 close to the weighing scale 21. A push rod 61 is fixed to the inner wall of the double-layer drain trough 6 along the direction of the weighing scale 21. A transmission screw group 62 is rotatably sleeved on one side of the inside of the two double-layer drain troughs 6. A second servo motor 63 is fixed to the outside of the first-layer transmission screw group 62 passing through one end of the bottom bracket 31. The second servo motor 63 is controlled by a controller. A transmission frame 64 is threadedly sleeved on the outside of the transmission screw group 62. A sponge roller 65 is rotatably sleeved on the inside of the transmission frame 64. The slotted height of the double-layer drain trough 6 is much smaller than the diameter of the sponge roller 65.

[0051] The top of the bottom bracket 31 is fixed with a lifting screw 7 on both sides of the waist bracket 32, and the lifting screw 7 is threadedly sleeved with a lifting nut 71 on the outside, and a lifting seat 72 is slidably sleeved on the outside of the lifting screw 7 above the lifting nut 71, and a positioning block 78 is fixed at the bottom of the lifting seat 72. An upper drainage trough 73 is provided inside the lifting seat 72, and a blade group 74 is fixed to the top plate and bottom plate of the inner cavity of the upper drainage trough 73. An upper screw 75 is rotatably sleeved on one side of the inner cavity of the upper drainage trough 73, and an upper transmission frame 76 is threadedly sleeved on the outside of the upper screw 75. An upper sponge roller 77 is rotatably sleeved on the inside of the upper transmission frame 76, and the slot height of the upper drainage trough 73 is much smaller than the diameter of the upper sponge roller 77.

[0052] The outer transmission sleeve of the end of the transmission screw group 62 away from the second servo motor 63 is connected with a belt 66, and the end of the upper screw 75 away from the second servo motor 63 is connected with the inner part of the belt 66; the auxiliary rod is rotatably sleeved on the side of the double-layer drain trough 6 opposite to the transmission screw group 62, and the sliding rod is rotatably sleeved on the side of the upper drain trough 73 opposite to the upper screw 75, and the auxiliary rod and the sliding rod respectively increase the stability of the transmission of the transmission frame 64 and the upper screw 75;

[0053] Specifically, when the controller controls the electric telescopic rod 8 to return, the standard test piece 23 is carried on the top of the sleeve plate 83 and the offset bracket 81 and falls, and the specific height of the output end of the electric telescopic rod 8 is controlled by the controller, and then the specific heights of the offset bracket 81, the sleeve plate 83 and the standard test piece 23 are controlled, so that the top height of the standard test piece 23 is located below the upper transmission frame 76, and the two ends of the standard test piece 23 are respectively against the two groups of positioning blocks 78, and then the second servo motor 63 is started by the controller, and the second servo motor 63 controls the rotation of the transmission screw group 62 in the first layer of the double-layer dewatering tank 6, and the double-layer The transmission screw group 62 in the first layer of the dewatering tank 6 drives the belt 66 to operate, and under the drive of the belt 66, the transmission screw group 62 in the second layer of the double-layer dewatering tank 6 rotates synchronously with the upper screw 75. During the rotation of the first-layer transmission screw group 62, the first-layer transmission frame 64 is driven to move along the length direction of the standard test piece 23, so that the sponge roller 65 inside the first-layer transmission frame 64 contacts the bottom of the standard test piece 23 and absorbs and removes the moisture at the bottom of the standard test piece 23, thereby ensuring the effect of draining and removing water from the bottom of the standard test piece 23, thereby improving the accuracy of the standard test piece 23 during waterproof testing;

[0054] At the same time, under the action of the belt 66, the transmission screw group 62 in the second layer of the double-layer dewatering tank 6 rotates synchronously. During the rotation of the second-layer transmission screw group 62, the second-layer transmission frame 64 is driven to move along the length direction of the standard test piece 23, and the sponge roller 65 in the second-layer transmission frame 64 is driven to contact the top of the weighing scale 21 during the movement, so that the second-layer sponge roller 65 moves with the transmission frame 64, and absorbs and removes the moisture on the top of the weighing scale 21, thereby ensuring the dryness of the weighing scale 21 before the standard test piece 23 is tested, ensuring that the weighing scale 21 only tests the moisture content in the standard test piece 23, thereby improving the accuracy of the waterproof test of the standard test piece 23;

[0055] Similarly, the upper screw 75 rotates under the drive of the belt 66. During the rotation of the upper screw 75, the upper transmission frame 76 is driven to move along the length direction of the standard test piece 23. During the movement, the upper transmission frame 76 drives the upper sponge roller 77 to contact the top of the standard test piece 23, and the upper sponge roller 77 follows the movement of the upper transmission frame 76 to absorb and remove the moisture on the top of the standard test piece 23, thereby ensuring the effect of draining and removing water from the top of the standard test piece 23, thereby improving the accuracy of the standard test piece 23 during waterproof testing;

[0056] After the two-layer sponge roller 65 and the upper sponge roller 77 complete the single adsorption and dehydration of the top of the weighing scale 21, the top and the bottom of the standard test piece 23, the two-layer sponge roller 65 enters the double-layer dehydration tank 6 near the first servo motor 11. Since the slot height of the double-layer dehydration tank 6 is much smaller than the sponge roller 65, when the sponge roller 65 enters the double-layer dehydration tank 6, the sponge roller 65 is squeezed, and the water absorbed inside is squeezed out. While the sponge roller 65 is subjected to the limited squeezing of the double-layer dehydration tank 6, the top rod 61 punctures the sponge roller 65, so that the number of openings on the surface of the sponge roller 65 increases, and then the roughness of the surface of the sponge roller 65 increases, thereby improving the subsequent sponge roller 65 adsorption and dehydration effect, and then improving the accuracy of the waterproof detection of the standard test piece 23 and the weighing scale 21;

[0057] Similarly, after the upper sponge roller 77 enters the upper drainage trough 73 near the side of the first servo motor 11, since the slot height of the upper drainage trough 73 is much smaller than the upper sponge roller 77, the upper sponge roller 77 is limited and squeezed by the upper drainage trough 73 after entering the upper drainage trough 73, so that the water adsorbed in the upper sponge roller 77 is squeezed out. At the same time, after the upper sponge roller 77 enters the upper drainage trough 73, it contacts the blade group 74, and the blade group 74 cuts the upper sponge roller 77, so that the opening on the surface of the upper sponge roller 77 is increased, and then the roughness of the surface of the upper sponge roller 77 is increased, and the contact area with the standard test piece 23 is increased, thereby improving the effect of the upper sponge roller 77 on the adsorption and dehydration of the standard test piece 23, and further improving the accuracy of the waterproof detection of the standard test piece 23;

[0058] After the upper sponge roller 77 and the sponge roller 65 complete the unidirectional adsorption and water removal, the second servo motor 63 is reversed through the controller, thereby reversing the first-layer transmission screw group 62, and under the drive of the belt 66, the two-layer transmission screw group 62 and the upper screw 75 are synchronously reversed, thereby making the transmission frame 64 drive the sponge roller 65 to move in the opposite direction, and making the upper transmission frame 76 drive the upper sponge roller 77 to move in the opposite direction. Since the two-layer sponge roller 65 and the upper sponge roller 77 are squeezed and drained by the double-layer drain trough 6 and the upper drain trough 73 respectively, the secondary adsorption and water removal effect of the sponge roller 65 and the upper sponge roller 77 in the reverse return stroke is improved, further improving the surface drainage and water removal effect of the standard test piece 23 and the weighing scale 21, and also improving the accuracy of the waterproof detection of the standard test piece 23 and the weighing scale 21.

[0059] It should be noted that, in the present invention, the bottom bracket 31 and the waist bracket 32 ​​are symmetrically arranged with the support frame 2 as the center, so the double-layer drain trough 6, the top rod 61, the lifting screw 7, the lifting nut 71, the lifting seat 72, the upper drain trough 73 and the blade group 74 are all symmetrically arranged, and the initial state of the sponge roller 65 is retracted inside the double-layer drain trough 6 on the side away from the first servo motor 11, and the initial state of the upper sponge roller 77 is retracted inside the upper drain trough 73 on the side away from the first servo motor 11. In the present invention, the standard test piece 23 is used as a standard part, and its area can be set to be equal to the top area of ​​the weighing scale 21. The width of the upper sponge roller 77 is wider than the width of the weighing scale 21, and the width of the sponge roller 65 is smaller than the width of the weighing scale 21, thereby ensuring that the upper sponge roller 77 and the sponge roller 65 are in the retracted state, and the standard test piece 23 will not be blocked by the upper screw 75 and the transmission screw group 62 during the lifting process;

[0060] When the thickness of the standard test piece 23 to be tested changes, the height of the lifting nut 71 can be adjusted, and the lifting seat 72 can be driven by the lifting nut 71 to adjust up and down outside the lifting screw 7, ensuring that the present invention can perform waterproof testing on standard test pieces 23 of different thicknesses.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
