Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and particularly to a ship paint adhesion detection device. Background Art

[0002] A paint adhesion detection device is a tool used to evaluate the bonding strength between a coating or paint film and a substrate, mainly including the following types: Cross cutter: Use a cutting tool to make 6 parallel cutting lines vertically and horizontally cross-cut on a prepared specified test panel (the spacing is determined by the coating thickness and substrate hardness). Paste transparent tape on the cut part of the coating (no adhesive tape is used for soft substrates), evenly tear off the adhesive tape, and check the damage of the cut coating to evaluate the adhesion. Pull-off adhesion tester: Stick an aluminum test pull head on the coating, and use a mechanical tensile testing machine with a scale to pull off the pull head, and read the pulling force of the aluminum head from the scale on the ruler. This instrument is small and can be used for on-site detection, but the instability of manual operation will affect the accuracy of the test results. The hull is exposed to the marine environment for a long time, and the paint film is easily affected by seawater corrosion and marine organism attachment, resulting in accelerated coating failure. It is necessary to frequently detect the adhesion to ensure the protection effect.

[0003] For example, the invention patent with the publication number CN108872069B provides an adhesion detector with a self-locking calibration device. When the detection block is connected to the actuating mechanism, it can be automatically fixed and calibrated. It is equipped with an energy collection mechanism and an energy storage mechanism, which can convert the mechanical energy generated during the test into electrical energy. However, in actual application, when detecting the hull itself, due to the difficult control of the hull angle, the hull has planes and curved surfaces. When pulling the detection device and the hull apart, the pulling direction is prone to deviation, and one side of the paint surface is easily lifted, resulting in inaccurate test results due to uneven force. Summary of the Invention

[0004] The present invention provides a ship paint adhesion detection device to solve the problem that when the existing detection device is pulled apart from the hull, one side of the paint surface is easily lifted, resulting in inaccurate test results.

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Referring to Figures 1 to 10 As shown, a ship paint adhesion detection device provided by an embodiment of the present invention includes a housing 100, a connecting pipe 150, an abutting chassis and a force balance mechanism. The housing 100 is vertically arranged, and the connecting pipe 150 is slidably arranged in the housing 100. The abutting chassis is located below the connecting pipe 150. The abutting chassis includes a paste disk 171 and a guide disk 172 arranged concentrically. The paste disk 171 and the guide disk 172 can be deformed. The paste disk 171 is located below the guide disk 172, and the paste disk 171 abuts against the test piece. Two first through holes and two second through holes are formed in the guide disk 172, and the two first through holes and the two second through holes are sequentially distributed along the circumferential direction of the guide disk 172. And each second through hole is located between two adjacent first through holes.

[0035] The force balance mechanism includes a connecting shaft 155, a balance assembly, and an adjustment assembly. The connecting shaft 155 is vertically arranged, and the upper end of the connecting shaft 155 is rotatably arranged in the connecting pipe 150. The balance assembly includes a first balance wheel 163, a second balance wheel 164, a first connecting rope 160, and a second connecting rope 161. The first balance wheel 163 and the second balance wheel 164 are both rotatably arranged in the connecting pipe 150, and both the first balance wheel 163 and the second balance wheel 164 can slide up and down.

[0036] The first connecting rope 160 is wound around the first balance wheel 163. The two ends of the first connecting rope 160 respectively pass through two first through holes and are connected to the paste plate 171. The second connecting rope 161 is wound around the second balance wheel 164. The two ends of the second connecting rope 161 respectively pass through two second through holes and are connected to the paste plate 171. The adjustment assembly makes the forces on the first connecting rope 160 and the second connecting rope 161 the same.

[0037] Press the paste plate 171 against the test piece to be tested. Since the paste plate 171 and the guiding plate 172 can be deformed, when encountering an arc-shaped test piece, press the paste plate 171 to make the paste plate 171 closely adhere to the test piece. Therefore, a ship paint adhesion detection device can adapt to flat test pieces and arc-shaped test pieces with different bending degrees, and has stronger adaptability.

[0038] When the connecting pipe 150 is inclined relative to the housing 100, its force application center and the axis of the paste plate 171 are offset. Due to the same tension on the same rope, even if the connecting shaft 155 and the paste plate 171 are not coaxial, and the centers of the first balance wheel 163, the second balance wheel 164, and the paste plate 171 are not concentric, the tensions of the two ends of the first connecting rope 160 on the paste plate 171 are the same, and the tensions of the two ends of the second connecting rope 161 on the paste plate 171 are also the same. At the same time, through the adjustment assembly, the forces on the first connecting rope 160 and the second connecting rope 161 are made the same, and the forces exerted by the first connecting rope 160 and the second connecting rope 161 on the paste plate 171 are the same, thereby preventing one side of the paste plate 171 from being lifted.

[0039] In this embodiment, a connecting frame 156 is slidably arranged in the connecting pipe 150. A connecting ring is fixedly arranged on the connecting frame 156, and the connecting ring is coaxially arranged with the connecting shaft 155. Two first sliding grooves and two second sliding grooves are formed on the connecting frame 156. The first sliding grooves and the second sliding grooves are both vertically arranged. The two first sliding grooves and the two second sliding grooves are both distributed along the circumferential direction of the connecting shaft 155, and each first sliding groove is located between the two second sliding grooves.

[0040] A first slider 165 that slides up and down is arranged in each first chute, and a second slider 166 that slides up and down is arranged in each second chute. A first rotating shaft is fixedly arranged on the first balance wheel 163. The first rotating shaft is arranged along the radial direction of the connecting shaft 155, and both ends of the first rotating shaft are rotatably arranged on the two first sliders 165. A second rotating shaft is fixedly arranged on the second balance wheel 164. The second rotating shaft is arranged along the radial direction of the connecting shaft 155, and both ends of the second rotating shaft are rotatably arranged on the two second sliders 166.

[0041] In this embodiment, the adjusting assembly includes a plurality of gears 154. First racks 1651 are arranged on both sides of the first slider 165 along the circumferential direction of the connecting shaft 155, and second racks 1661 arranged vertically are arranged on both sides of the second slider 166 along the circumferential direction of the connecting shaft 155. Both the first rack 1651 and the second rack 1661 are arranged vertically. The gears 154 are rotatably arranged on the connecting shaft 155, and the axis of the gear 154 is arranged along the radial direction of the connecting shaft 155. Each gear 154 is arranged between the first slider 165 and the second slider 166, and the gear 154 meshes with the first rack 1651 and the second rack 1661.

[0042] When the force application center of the connecting pipe 150 on the adhesive disc 171 is offset from the axis of the adhesive disc 171, resulting in the tension on the first connecting rope 160 being greater than the tension on the second connecting rope 161. The first connecting rope 160 drives the two first sliders 165 to move upward through the first balance wheel 163. At this time, the movement of the first slider 165 causes the gear 154 to rotate, and the gear 154 drives the second slider 166 to move downward through the second rack 1661, realizing the transmission and balance of force. At this time, the magnitudes of the forces on the first connecting rope 160 and the second connecting rope 161 are the same.

[0043] In this embodiment, two first guide wheels 162 and two second guide wheels 169 are rotatably arranged on the connecting frame 156. The two first guide wheels 162 and the two second guide wheels 169 are both distributed along the circumferential direction of the connecting shaft 155. The first guide wheel 162 and the second guide wheel 169 are at the same horizontal height, and the first guide wheel 162 is between two adjacent second guide wheels 169. The first connecting rope 160 bypasses the two first guide wheels 162, and the second connecting rope 161 bypasses the two second guide wheels 169.

[0044] Since the first guide wheel 162 and the second guide wheel 169 are at the same horizontal height, after being guided by the first guide wheel 162 and the second guide wheel 169, when the lengths of the first connecting ropes 160 on both sides of the first balance wheel 163 are the same and the lengths of the second connecting ropes 161 on both sides of the second balance wheel 164 are the same, the angle between the first connecting rope 160 and the horizontal plane is the same as the angle between the second balance wheel 164 and the horizontal plane, thereby achieving the force balance of the paste disk 171.

[0045] In this embodiment, the force balance mechanism further includes a sliding assembly, and the sliding assembly includes a first sliding rod 151, a second sliding rod 152 and a sliding block 153. The first sliding rod 151 is arranged along a first direction, and the first sliding rod 151 is slidably arranged in the connecting pipe 150 along a second direction. Both the first direction and the second direction are the radial directions of the connecting pipe 150, and the first direction is perpendicular to the second direction. The second sliding rod 152 is arranged along the second direction, and the second sliding rod 152 is slidably arranged in the connecting pipe 150 along the first direction.

[0046] The sliding block 153 is provided with a first limiting groove and a second limiting groove. The first limiting groove is arranged along the first direction, and the first sliding rod 151 is slidably arranged in the first limiting groove. The second limiting groove is arranged along the second direction, and the second sliding rod 152 is slidably arranged in the second limiting groove.

[0047] In this embodiment, a first connecting head 1551 is arranged at the upper end of the connecting shaft 155, and the first connecting head 1551 is ball-jointed with the sliding block 153. When the connecting pipe 150 is inclined relative to the housing 100, the connecting shaft 155 remains in a vertical state under the action of gravity and the traction of the first connecting rope 160 and the second connecting rope 161.

[0048] In this embodiment, a plurality of bending grooves 173 are formed on both the paste disk 171 and the guide disk 172, and the bending grooves 173 provide a deformation margin for the deformation of the paste disk 171 and the guide disk 172.

[0049] A first guide pipe is fixedly arranged in each first through hole, and a second guide pipe is fixedly arranged in each second through hole. The first connecting rope 160 passes through the first guide pipe, and the second connecting rope 161 passes through the second guide pipe. When the paste disk 171 and the guide disk 172 are horizontally arranged, both the first guide pipe and the second guide pipe are perpendicular to the paste disk 171 and the guide disk 172. When the paste disk 171 and the guide disk 172 are deformed into an arc shape, both the first guide pipe and the second guide pipe are perpendicular to the tangents of the arc-shaped paste disk 171 and the guide disk 172.

[0050] Through the provided first guide tube and second guide tube, when the paste plate 171 and the guide plate 172 are horizontally arranged, both the first connecting rope 160 and the second connecting rope 161 between the paste plate 171 and the guide plate 172 are perpendicular to the paste plate 171. After the paste plate 171 and the guide plate 172 are deformed into an arc shape, both the first connecting rope 160 and the second connecting rope 161 between the paste plate 171 and the guide plate 172 are perpendicular to the tangent of the paste plate 171.

[0051] Therefore, due to the consistent tension on the same rope, even if the connecting shaft 155 and the paste plate 171 are not coaxial, and the centers of the first balance wheel 163, the second balance wheel 164 and the paste plate 171 are not concentric, the tensions of the two ends of the first connecting rope 160 on the paste plate 171 are consistent, and the tensions of the two ends of the second connecting rope 161 on the paste plate 171 are also consistent.

[0052] In this embodiment, two limiting blocks 176 are fixedly arranged between the paste plate 171 and the guide plate 172. The two limiting blocks 176 are distributed along the circumferential direction of the paste plate 171, and limiting holes are formed in each limiting block 176. A ship paint surface adhesion detection device further includes a limiting screw 175, and the limiting screw 175 is arranged along the radial direction of the paste plate 171. The limiting screw 175 is arranged in the two limiting holes and is connected to the limiting block 176 through a nut. When encountering an arc-shaped test piece, press the paste plate 171 to make the paste plate 171 closely adhere to the test piece, and then tighten the limiting screw 175 to limit the deformation of the paste plate 171.

[0053] In this embodiment, a ship paint surface adhesion detection device further includes a driving mechanism. The driving mechanism includes a hydraulic cylinder 110 and a pressing rod 130. The pressing rod 130 is vertically arranged, and the pressing rod 130 is slidably arranged up and down in the housing 100. A limiting disk 131 is fixedly arranged on the pressing rod 130. The limiting disk 131 and the pressing rod 130 are coaxially arranged. The limiting disk 131 divides the housing 100 into a first chamber 101 and a second chamber 102. The first chamber 101 is located above the second chamber 102. An oil delivery pipe 113 is arranged on the hydraulic cylinder 110, and the oil delivery pipe 113 is communicated with the first chamber 101. A ball groove 136 is formed at the lower end of the pressing rod 130. A second connecting head 1501 is fixedly arranged at the upper end of the connecting pipe 150, and the second connecting head 1501 is rotatably arranged in the ball groove 136. The connecting pipe 150 is located in the second chamber 102.

[0054] In this embodiment, the diameter of the second connector 1501 is greater than that of the connecting pipe 150, and the lower side surface where the second connector 1501 and the connecting pipe 150 are fixedly connected forms a contact surface. A ship paint adhesion detection device further includes a clamping mechanism, and the clamping mechanism includes a plurality of spheres 135. A plurality of mounting grooves 134 are formed at the lower end of the pressing rod 130, and the plurality of mounting grooves 134 are sequentially distributed along the circumference of the pressing rod 130. Each sphere 135 is slidably disposed in one mounting groove 134. The sphere 135 is used to abut against the contact surface.

[0055] A tapered groove 143 is formed at the lower end of the housing 100, and the tapered groove 143 is coaxially arranged with the pressing rod 130. The radius of the upper end of the tapered groove 143 is smaller than that of the lower end. The tapered groove 143 is used to abut against the sphere 135. A spring 141 is fixedly arranged on the pressing rod 130, the spring 141 is arranged vertically, and the spring 141 is fixedly connected with the housing 100.

[0056] The housing 100 is sleeved on the connecting pipe 150, and the second connector 1501 is made to enter the ball groove 136. Since the sphere 135 abuts against the tapered groove 143 at this time, the second connector 1501 can enter the ball groove 136 after passing through the sphere 135. Then, the housing 100 is further pressed downward, so that the housing 100 moves downward relative to the pressing rod 130, the spring 141 is compressed, the sphere 135 is separated from the tapered groove 143, the sphere 135 enters the interior of the housing 100, and the housing 100 pushes the sphere 135 to abut against the second contact surface of the second connector 1501, and restricts the movement of the second connector 1501 relative to the ball groove 136, thereby connecting the pressing rod 130 and the connecting pipe 150.

[0057] Working process: In the initial state, the sphere 135 abuts against the tapered groove 143, and the pressing rod 130 is disconnected from the second connector 1501.

[0058] First, glue is applied to the paste plate 171, and then the paste plate 171 is pressed tightly against the test piece. Since the paste plate 171 and the guiding plate 172 can be deformed, when encountering an arc-shaped test piece, the paste plate 171 is pressed to make the paste plate 171 closely adhere to the test piece, and then the limiting screw 175 is tightened to limit the deformation of the paste plate 171. Therefore, a ship paint adhesion detection device can be adapted to flat test pieces and arc-shaped test pieces with different bending degrees, and has stronger adaptability.

[0059] After the glue is firmly attached, the housing 100 is sleeved on the connecting tube 150, and the second connecting head 1501 is inserted into the ball groove 136. Since the ball 135 and the tapered groove 143 are against each other at this time, the second connecting head 1501 can pass through the ball 135 and enter the ball groove 136. Then, the housing 100 is pressed downwardly again, so that the housing 100 moves downward relative to the pressing rod 130, the spring 141 is compressed, the ball 135 and the tapered groove 143 are out of contact, the ball 135 enters the interior of the housing 100, and the housing 100 pushes the ball 135 and the second contact surface of the second connecting head 1501 to abut against each other, and limits the movement of the second connecting head 1501 relative to the ball groove 136, thereby connecting the pressing rod 130 and the connecting tube 150.

[0060] The hydraulic cylinder 110 is started, and the hydraulic cylinder 110 inhales air, driving the lower pressure rod 130 to move upward, and the lower pressure rod 130 drives the connecting pipe 150 to move upward, and the connecting pipe 150 drives the adhesive plate 171 to move upward through the first connecting rope 160 and the second connecting rope 161, so that the paint surface on the test piece is pulled out through the adhesive plate 171.

[0061] The contact surface may be uneven due to production errors, and the contact surface may be uneven due to wear caused by long-term use, which may cause the connection tube 150 to tilt relative to the housing 100 when multiple balls 135 and the contact surface abut against each other. In addition, improper storage may cause the balls 135 or the contact surface to rust, which may cause the connection tube 150 to tilt when the housing 100 and the connection tube 150 are connected.

[0062] When the connecting tube 150 is tilted relative to the housing 100, the connecting tube 150 drives the pasting plate 171 to move upward, and the force center and the axis of the pasting plate 171 are offset, which will cause uneven force on the pasting plate 171, and then one side of the pasting plate 171 tends to be lifted, and then when the pasting plate 171 sticks to the paint surface, the paint surface is abnormally peeled off, resulting in the sample cannot be retested or reworked, increasing material and time costs. In addition, the test results are distorted, misleading quality judgment, and may trigger unnecessary process adjustments, resulting in increased production costs.

[0063] Since the first connector 1551 on the connecting shaft 155 is spherically hinged with the sliding block 153, the connecting shaft 155 is still in a vertical state due to gravity and the traction of the first connecting rope 160 and the second connecting rope 161. The force exerted by the connecting shaft 155 on the first balance wheel 163 and the second balance wheel 164 through the first sliding block 165 and the second sliding block 166 is still vertically upward.

[0064] However, due to the inclination of the connecting pipe 150, the connecting shaft 155 and the pasting disk 171 may be misaligned. Through the provided first guiding pipe and second guiding pipe, when the pasting disk 171 and the guiding disk 172 are horizontally arranged, both the first connecting rope 160 and the second connecting rope 161 between the pasting disk 171 and the guiding disk 172 are perpendicular to the pasting disk 171. When the pasting disk 171 and the guiding disk 172 are deformed into an arc shape, both the first connecting rope 160 and the second connecting rope 161 between the pasting disk 171 and the guiding disk 172 are perpendicular to the tangent of the pasting disk 171.

[0065] Therefore, due to the consistent tension on the same rope, even if the connecting shaft 155 and the pasting disk 171 are misaligned, and the centers of the first balance wheel 163, the second balance wheel 164 and the pasting disk 171 are not concentric, the tensions of the two ends of the first connecting rope 160 on the pasting disk 171 are consistent, and the tensions of the two ends of the second connecting rope 161 on the pasting disk 171 are also consistent.

[0066] When the force application center of the connecting pipe 150 on the pasting disk 171 is offset from the axis of the pasting disk 171, resulting in the tension on the first connecting rope 160 being greater than the tension on the second connecting rope 161. The first connecting rope 160 drives the two first sliders 165 to move upward through the first balance wheel 163. At this time, the movement of the first sliders 165 causes the gear 154 to rotate, and the gear 154 drives the second slider 166 to move downward through the second rack 1661, realizing the transmission and balance of force. At this time, the magnitudes of the forces on the first connecting rope 160 and the second connecting rope 161 are consistent, and the forces exerted by the first connecting rope 160 and the second connecting rope 161 on the pasting disk 171 are consistent, thereby preventing one side of the pasting disk 171 from being lifted.

[0067] When the connecting shaft 155 and the pasting disk 171 are misaligned, at this time, the centers of the first balance wheel 163, the second balance wheel 164 and the pasting disk 171 are not concentric. The lengths of the first connecting ropes 160 on both sides of the first balance wheel 163 are inconsistent, and the lengths of the second connecting ropes 161 on both sides of the second balance wheel 164 are inconsistent. The angles between the first connecting ropes 160 on both sides of the first balance wheel 163 and the horizontal plane are inconsistent, and the angles between the second connecting ropes 161 on both sides of the second balance wheel 164 and the horizontal plane are inconsistent. As a result, when the connecting pipe 150 moves upward, the horizontal component forces of the first connecting ropes 160 on both sides of the first balance wheel 163 are inconsistent, and the horizontal component forces of the second connecting ropes 161 on both sides of the second balance wheel 164 are inconsistent. This leads to a horizontal thrust on the pasting disk 171 by the first connecting rope 160 and the second connecting rope 161. When the pasting disk 171 moves horizontally, it will rub against the specimen, affecting the test results.

[0068] Therefore, in the process of making the forces on the first connecting rope 160 and the second connecting rope 161 the same through the force balance mechanism, the first connecting rope 160 and the second connecting rope 161 drive the sliding block 153 to slide, so that the sliding block 153 drives the connecting shaft 155 to slide until the connecting shaft 155 and the paste disk 171 are coaxially arranged. At this time, the lengths of the first connecting rope 160 on both sides of the first balance wheel 163 are the same, and the magnitudes of the horizontal component forces on both sides are the same and cancel each other out. The lengths of the second connecting rope 161 on both sides of the second balance wheel 164 are the same, and the magnitudes of the horizontal component forces on both sides are the same and cancel each other out, preventing the detection result from being affected.

[0069] After the detection is completed, the housing 100 is no longer pressed. When the spring 141 resets, the housing 100 moves upward relative to the pressing rod 130, and the sphere 135 comes to the conical groove 143. At this time, the sphere 135 can move outward. Then, the pressing rod 130 is pulled outwards so that the pressing rod 130 is disconnected from the connecting pipe 150.

[0070] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
