Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of fireproof coating detection, and particularly relates to a fireproof coating spraying quality detection device. BACKGROUND

[0002] Fireproof coating is a kind of coating that can improve the fire resistance of materials, slow down the spread of flame, or prevent burning for a certain period of time by being brushed or sprayed on the surface of materials. After the fireproof coating is formed by spraying, special detection personnel will detect the fireproof coating layer. For example, a fireproof coating spraying quality detection device is disclosed in patent CN219391611U.

[0003] The existing detection device can only roughly determine whether there is a cavity inside the fireproof coating after spraying, but the shape and size of the cavity cannot be determined, which is very unfavorable for subsequent repair work and cannot provide accurate information for repair.

[0004] At the same time, when the sprayed surface of the fireproof coating is an arc-shaped curved surface, the extrusion force on the coating near the edge of the detection block is much smaller than that on the central part. This uneven pressure distribution will affect the judgment of the internal cavity of the coating layer and also make some cavities in the area with insufficient pressure cannot be accurately detected. At the same time, when using the detection block to extrude and detect on the curved surface, it is difficult to maintain a stable and uniform extrusion force of the detection block due to the curvature and irregularity of the curved surface, which may cause cavities of the same size to exhibit different deformation degrees at different positions, thereby interfering with the judgment of the detection personnel.

[0036] The marking assembly 39 is arranged on the rear side wall of the rotating plate 11 and used for marking the shape and size of the cavity.

[0040] The lower side wall of the heating barrel 46 is fixedly connected with a rubber plug 51. The rear end of the thickness measuring probe 17 penetrates through the rubber plug 51, so that the hot air is prevented from being discharged from the lower side of the heating barrel 46.

[0041] The operation principle of the present application is described as follows: the operator moves the detection device to the surface to be detected which is sprayed with fireproof paint, and aligns the back side of the rotating plate 11 to the surface to be detected, then the operator sends an electric signal to the control cabinet 2 through the display screen on the surface of the control cabinet 2, after receiving the electric signal, the control cabinet 2 first controls the two adjusting hydraulic cylinders 6 to work, the two adjusting hydraulic cylinders 6 drive the second lead screw linear module 7 and the rotating plate 11 and other components to move towards the surface to be detected, in the moving process of the rotating plate 11, the detection cylinder 201 is driven to move together, when the detection cylinder 201 contacts with the surface to be detected (the detection cylinder 201 is longer than the thickness measuring cylinder 13 and the marking cylinder 391), the change of the moving resistance of the rotating plate 11 is detected by the first pressure sensor 10, the first pressure sensor 10 sends an electric signal to the control cabinet 2, after receiving the electric signal, the control cabinet 2 controls the two adjusting hydraulic cylinders 6 to stop working, then the control cabinet 2 controls the micro air pump 49 and the heating wire in the heating box 47 to work at the same time for one minute, the micro air pump 49 sends the heated gas to the heating cylinder 46 through the hose 50, and sends the gas to the thickness measuring probe 17 and the fireproof paint through the gas outlet holes on the surface of the heating cylinder 46, so as to heat the fireproof paint and the thickness measuring probe 17, and make the fireproof paint soften appropriately, so as to facilitate the insertion of the thickness measuring probe 17;

[0042] When the heating work is carried out for one minute, the control cabinet 2 controls the first electric push rod 121 to work, and the first electric push rod 121 drives the thickness measuring cylinder 13 to move towards the fireproof coating through the second pressure sensor 122. When the thickness measuring cylinder 13 contacts the fireproof coating, the second pressure sensor 122 detects the change of the moving resistance of the thickness measuring cylinder 13, and sends an electric signal to the control cabinet 2. The control cabinet 2 controls the first electric push rod 121 to stop working and controls the second electric push rod 14 to work. The second electric push rod 14 drives the push plate 16 and the thickness measuring probe 17 to move towards the fireproof coating through the third pressure sensor 15, and the push plate 16 drives the conductive plate 18 to move together. When the thickness measuring probe 17 penetrates the fireproof coating and contacts the surface base material to be measured, the moving resistance of the thickness measuring probe 17 changes rapidly. After the third pressure sensor 15 detects the change, the third pressure sensor 15 controls the second electric push rod 14 to stop working through the control cabinet 2, and controls the conductive plate 18 to be electrically connected with the power supply 3. The right end of the conductive plate 18 is always in contact with the resistance plate 19 during movement. The rear end of the resistance plate 19 is electrically connected with the control cabinet 2. When the conductive plate 18 is electrically connected with the power supply 3, the current in the power supply 3 is transmitted to the control cabinet 2 through the conductive plate 18 and the resistance plate 19. When the thickness of the fireproof coating is thicker, the conductive plate 18 contacts the position close to the rear end of the resistance plate 19. Under the condition that the voltage of the power supply 3 is unchanged, the current intensity transmitted to the control cabinet 2 is larger. After the control cabinet 2 receives the larger current intensity, it is analyzed that the fireproof coating is thicker. When the cavity inside the fireproof coating is detected subsequently, larger pressure is required. At the same time, the control cabinet 2 also displays the thickness of the fireproof coating on the surface screen, so as to facilitate the operator to judge whether the thickness of the fireproof coating is qualified or not.

[0043] 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 to the set position on the rear side, and the piston seat 36 is used to transport the hydraulic oil in the injection cylinder 351 into the hollow plate 21 and the plurality of piston mechanisms 37, so that the plurality of piston mechanisms 37 drive the limiting plate 38 to move upward, and the limiting plate 38 pushes the fifth pressure sensor 24 and the detection rod 23, when the push-pull hydraulic cylinder 352 stops working, the control cabinet 2 controls the detection hydraulic cylinder 202 to work, the detection hydraulic cylinder 202 drives the hollow plate 21, the piston mechanism 37, the limiting plate 38 and the detection rod 23 to move together to the set position on the rear side through the fourth pressure sensor 52, and the detection rod 23 pushes the hydraulic oil in the sealing cylinder 25 through the piston seat 36, drives the sealing cylinder 25 and the detection block 28 to move together to the direction close to the fire retardant coating, in the movement process of the detection hydraulic cylinder 202, the control cabinet 2 also controls the plurality of control valves 34 to be in the open state, when the detection block 28 contacts the fire retardant coating, the detection block 28 is hindered by the fire retardant coating and drives the sealing cylinder 25 to stop moving, and the detection rod 23 still continues to move under the pushing of the detection hydraulic cylinder 202, the detection rod 23 extrudes the piston oil in the sealing cylinder 25 through the piston seat 36, so that the piston oil is stored in the telescopic water bag 31 through the delivery pipe 33 and the ring pipe 30, when the detection hydraulic first stops moving, the control cabinet 2 controls the control valve 34 to close, and controls the push-pull hydraulic cylinder 352 to drive the piston seat 36 to retract, so that the hydraulic oil in the piston mechanism 37 and the hollow plate 21 is returned to the injection cylinder 351 for storage, and the limiting of the lower end of the detection rod 23 is released, then the control cabinet 2 controls the moving end of the detection hydraulic cylinder 202 to continue to move backward, the detection hydraulic cylinder 202 drives the hollow plate 21 to move through the fourth pressure sensor 52, and the hollow plate 21 extrudes the fifth pressure sensor 24 and the detection rod 23 through the spring on the surface, according to the above principle, the detection rod 23 drives the sealing cylinder 25 and the detection block 28 to continue to move, the detection block 28 extrudes the fire retardant coating, and the fourth pressure sensor 52 detects that the resistance received by the hollow plate 21 reaches the set threshold value (when the fire retardant coating is thicker, the resistance received by the hollow plate 21 is greater, which is detected by the thickness measuring assembly 12), the fourth pressure sensor 52 controls the detection hydraulic cylinder 202 to stop working through the control cabinet 2, at this time, when there is no cavity in the fire retardant coating, the extrusion forces of the plurality of fifth pressure sensors 24 are the same, when there is a cavity in a region of the fire retardant coating, the detection block 28 corresponding to the region will collapse the cavity and insert into the fire retardant coating to a certain depth, and the fifth pressure sensor 24 corresponding to the detection block 28 will bear a relatively small extrusion force, when the control cabinet 2 detects that the data of the fifth pressure sensor 24 is different from those of the other fifth pressure sensors 24, the control cabinet 2 controls the detection hydraulic cylinder 202 and the adjusting hydraulic cylinder 6 to retract to the initial position, and controls the adjusting motor 9 to work,The adjusting motor 9 drives the marking cylinder 391 and the detection cylinder 201 to rotate 180 degrees through the rotating plate 11, so that the marking cylinder 391 moves to the detection area, then the control cabinet 2 controls the magnetic control valve 41 corresponding to the fifth pressure sensor 24 to open, and controls the micro pump 44 to work, the micro pump 44 sprays the pigment stored in the marking cylinder 391 through the hollow disc 392 and the corresponding marking pipe 40 and marking nozzle 42, and marks in the fireproof coating cavity area, the diameter of the marking point is 0.5 cm, (since the detection block 28 is small in volume, when the cavity volume is large, multiple detection blocks 28 will detect the cavity, and the surface of the fireproof coating will be sprayed and marked according to the shape of the cavity), which is convenient for the operator to judge the shape and size of the cavity for subsequent repair work;

[0044] When the detection hydraulic cylinder 202 retracts, the control cabinet 2 also controls the multiple control valves 34 to reopen, when the detection block 28 and the fireproof coating are separated, under the action of the spring force between the sealing cylinder 25 and the guide cylinder 27, the detection rod 23 drives the piston plate 26 to slide in the sealing cylinder 25, so that the internal hydraulic pressure of the sealing cylinder 25 becomes smaller, under the action of the hydraulic pressure difference, the hydraulic oil in the telescopic water bag 31 flows back to the storage in the sealing cylinder 25, which is convenient for subsequent use.

[0045] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application should be included in the protection scope of the present application.
