Description

Technical Field

[0001] The invention belongs to the technical field of fire retardant coating detection, and in particular relates to a fire retardant coating spraying quality detection device. Background Art

[0002] Fire retardant coatings are made by brushing or spraying the coating on the surface of the material, which can improve the fire resistance of the material, slow down the spread of flames, or prevent combustion for a certain period of time. This type of coating is called fire retardant coating. After the fire retardant coating is sprayed, special inspectors will inspect the fire retardant coating layer. For example, a fire retardant coating spraying quality inspection device is proposed in patent announcement number CN219391611U.

[0003] When detecting cavities inside fire retardant coatings after spraying, existing detection devices can only roughly determine whether there are cavities inside the fire retardant coatings, but cannot determine the shape and size of the cavities. This is very unfavorable for subsequent repair work and cannot provide accurate information for repair. At the same time, when the spray surface of the fire retardant coating is an arc-shaped curved surface, the extrusion pressure on the coating near the edge of the detection block is much smaller than the extrusion pressure on the center. Such uneven pressure distribution will affect the judgment of the internal cavity of the coating, and will also make some cavities unable to be accurately detected in areas with insufficient pressure. At the same time, when using the detection block for extrusion detection on the curved surface, due to the curvature and irregularity of the curved surface, it is difficult to make the detection block maintain a stable and uniform extrusion force, which may cause cavities of the same size to show different degrees of deformation at different positions, thereby interfering with the judgment of the detection personnel.

The lower side wall of the hollow plate 21 is fixedly connected to a shaping component 35, which can detect the cavity condition below the fire retardant coating. The marking component 39 is arranged on the rear side wall of the rotating plate 11 and is used to mark the shape and size of the cavity. The thickness measuring component 12 is arranged at the center of the rear side wall of the rotating plate 11. The marking component 39 and the detection component 20 are symmetrically arranged about the thickness measuring component 12.

The discharge end of the micro pump 44 is connected to the hollow disk 392, so that the shape and size of the cavity can be displayed to the operator.

[0021] The shaping component 35 includes an injection cylinder 351 fixedly connected to the front side wall of the hollow plate 21.

The movable end of the piston mechanism 37 is connected to a limiting plate 38, which can change the shape of the multiple detection blocks 28 according to the shape of the surface to be measured.

[0022] The right side wall of the marking cylinder 391 is fixedly connected to a feed pipe 45 , and a sealing cap is threadedly sleeved on the right end of the feed pipe 45 , which can transport pigment into the marking cylinder 391 .

[0023] The right inner wall of the thickness measuring cylinder 13 is fixedly connected to a heating cylinder 46 which is sleeved on the outside of the thickness measuring probe 17 through a bracket.

[0024] A rubber plug 51 is fixedly connected to the lower side wall of the heating cylinder 46 , and the rear end of the thickness measuring probe 17 passes through the rubber plug 51 , which can prevent hot air from being discharged from the bottom of the heating cylinder 46 .

[0025] The operating principle of the present invention is now explained as follows: the operator moves the detection device to the surface to be tested that has been sprayed with fire retardant paint, and aligns the rear side of the rotating plate 11 with the surface to be tested. Then the operator transmits an electrical signal to the control cabinet 2 through the display screen on the surface of the control cabinet 2. After receiving the electrical signal, the control cabinet 2 first controls the two adjusting hydraulic cylinders 6 to work. The two adjusting hydraulic cylinders 6 will drive the second screw linear module 7 and the rotating plate 11 and other components to move toward the direction of the surface to be tested. During the movement of the rotating plate 11, it will drive the detection cylinder 201 to move together. When the detection cylinder 201 contacts the surface to be tested (the length of the detection cylinder 201 is longer than the thickness measuring cylinder 13 and the marking cylinder 391), the detection cylinder 201 will move with the detection cylinder 201. long), the change in the resistance to movement of the rotating plate 11 will be detected by the first pressure sensor 10, and the first pressure sensor 10 will transmit an electrical signal to the control cabinet 2. After receiving the electrical signal, the control cabinet 2 will control the two regulating hydraulic cylinders 6 to stop working. Then the control cabinet 2 will control the micro air pump 49 and the heating wire inside the heating box 47 to work simultaneously for one minute. The micro air pump 49 will transport the heated gas into the heating cylinder 46 through the hose 50, and transport the gas to the thickness measuring probe 17 and the fire retardant coating through the air outlet on the surface of the heating cylinder 46, thereby heating the fire retardant coating and the thickness measuring probe 17 to soften the fire retardant coating appropriately, thereby facilitating the insertion of the thickness measuring probe 17; After the heating work is carried out for one minute, the control cabinet 2 will control the first electric push rod 121 to work, and the first electric push rod 121 will drive the thickness measuring cylinder 13 to move in the direction close to the fire retardant coating through the second pressure sensor 122. When the thickness measuring cylinder 13 contacts the fire retardant coating, the change in the movement resistance of the thickness measuring cylinder 13 will be detected through the second pressure sensor 122, and the second pressure sensor 122 will send an electrical signal to the control cabinet 2, and the control cabinet 2 will control the first electric push rod 121 to stop working and control the second electric push rod 14 to work. The second electric push rod 14 will drive the push plate 16 and the thickness measuring probe 17 to move in the direction close to the fire retardant coating through the third pressure sensor 15, and the push plate 16 will drive the conductive plate 18 to move together. When the thickness measuring probe 17 passes through the fire retardant coating and contacts the substrate to be measured, the movement resistance of the thickness measuring probe 17 will change rapidly. After the third pressure sensor 15 detects this change, the first electric push rod 121 will stop working and control the second electric push rod 14 to work. The third pressure sensor 15 will control the second electric push rod 14 to stop working through the control cabinet 2, and control the conductive plate 18 to be electrically connected to the power supply 3. The right end of the conductive plate 18 is always in contact with the resistor plate 19 during the movement, and the rear end of the resistor plate 19 is electrically connected to the control cabinet 2. When the conductive plate 18 is electrically connected to the power supply 3, the current inside the power supply 3 will be transmitted to the control cabinet 2 through the conductive plate 18 and the resistor plate 19. When the thickness of the fire retardant coating is thicker, the conductive plate 18 will be in contact with the position of the resistor plate 19 near the rear end. When the voltage of the power supply 3 remains unchanged, the current intensity transmitted to the control cabinet 2 is larger. After receiving the larger current intensity, the control cabinet 2 will analyze that the fire retardant coating is thicker. When the cavity inside the fire retardant coating is subsequently detected, a larger pressure is required. At the same time, the control cabinet 2 will also display the thickness of the fire retardant coating on the screen on the surface, so that the operator can judge whether the thickness of the fire retardant coating sprayed is qualified. Then the control cabinet 2 controls the first electric push rod 121 and the second electric push rod 14 to retract to the initial state, and controls the push-pull hydraulic cylinder 352 to work. The push-pull hydraulic cylinder 352 drives the piston seat 36 to move backward to the set position, and uses the piston seat 36 to transport the hydraulic oil in the injection cylinder 351 to the hollow plate 21 and multiple piston mechanisms 37, so that the multiple piston mechanisms 37 all drive the limit plate 38 to move upward, and use the limit plate 38 to push the fifth pressure sensor 24 and the detection rod 23. When the push-pull hydraulic cylinder 352 stops working, the control cabinet 2 will control the detection hydraulic cylinder 202 to work, and the detection hydraulic cylinder 202 drives the hollow plate 21, the piston mechanism 37, the limit plate 38 and the detection rod 23 to move backward to the set position through the fourth pressure sensor 52. When the detection block 28 comes into contact with the fire retardant coating, the detection block 28 will drive the sealing cylinder 25 to stop moving due to the obstruction of the fire retardant coating, while the detection rod 23 will continue to move under the push of the detection hydraulic cylinder 202. The detection rod 23 will squeeze the piston oil in the sealing cylinder 25 through the piston seat 36, so that the piston oil enters the telescopic water bag 31 through the delivery pipe 33 and the annular pipe 30 for storage. When the detection hydraulic pressure stops moving for the first time, the control cabinet 2 will control the control valve 34 to close. The control cabinet 2 then controls the movable end of the detection hydraulic cylinder 202 to continue to move backward, and the detection hydraulic cylinder 202 drives the hollow plate 21 to move through the fourth pressure sensor 52, and the hollow plate 21 will squeeze the fifth pressure sensor 24 and the detection rod 23 through the spring on the surface. Referring to the above principle, the detection rod 23 will drive the sealing cylinder 25 and the detection block 28 to continue to move, and the detection block 28 will be used to squeeze the fire retardant coating, and the fourth pressure sensor 52 will detect that the resistance of the hollow plate 21 reaches the set threshold (the thickness measuring component 12 detects the fire retardant coating). The thicker the fire retardant coating, the greater the resistance the hollow plate 21 encounters). The fourth pressure sensor 52 will control the detection hydraulic cylinder 202 to stop working through the control cabinet 2. At this time, when there is no cavity inside the fire retardant coating, multiple fifth pressure sensors 24 are subjected to the same squeezing force from the spring. When there is a cavity in a certain area of the fire retardant coating, the detection block 28 corresponding to the area will collapse the cavity and be inserted into the fire retardant coating to a certain depth. The fifth pressure sensor 24 corresponding to the detection block 28 will be subjected to a relatively small squeezing force. When the control cabinet 2 detects that the data of the fifth pressure sensor 24 is different from that of other fifth pressure sensors 24, the control cabinet 2 will control the detection hydraulic cylinder 202 and the adjustment hydraulic cylinder 6 to retract to the initial position, and control the adjustment motor 9 to work.The regulating motor 9 drives the marking cylinder 391 and the detection cylinder 201 to rotate simultaneously 180 degrees via the rotating plate 11, moving the marking cylinder 391 to the detection area. The control cabinet 2 then controls the magnetic control valve 41 corresponding to the fifth pressure sensor 24 to open and the micro pump 44 to operate. The micro pump 44 sprays the pigment stored in the marking cylinder 391 through the hollow disk 392, the corresponding marking tube 40, and the marking nozzle 42, marking the cavity area of the fire retardant coating. The marking point diameter is 0.5 cm. (Due to the small size of the detection block 28, when the cavity volume is large, multiple detection blocks 28 will detect the cavity, and the surface of the fire retardant coating will be sprayed and marked according to the shape of the cavity.) This facilitates the operator's subsequent judgment of the shape and size of the cavity and facilitates subsequent repair work. When the detection hydraulic cylinder 202 retracts, the control cabinet 2 will also control multiple control valves 34 to reopen. When the detection block 28 is separated from the fire-retardant coating, under the action of the spring force between the sealing cylinder 25 and the guide cylinder 27, the detection rod 23 will drive the piston plate 26 to slide in the sealing cylinder 25, so that the hydraulic pressure inside the sealing cylinder 25 becomes smaller. Under the action of the hydraulic pressure difference, the hydraulic oil inside the telescopic water bag 31 will flow back to the sealing cylinder 25 for storage, which is convenient for subsequent use.
