Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a fireproof coating fireproof testing device. Background Technology

[0002] Fire-retardant coatings are made from non-combustible materials with low thermal conductivity. They are applied to the outside of the object being protected, and the coatings block the air from entering, thus providing fire protection. After the fire-retardant coatings are manufactured, they need to be tested for flame resistance using fire-retardant testing equipment.

[0003] A search revealed a Chinese patent application (CN202121554007.X) proposing a fire-retardant coating testing device. This device addresses the problems in existing technologies where the temperature and thickness of fire-retardant coatings cannot be simultaneously measured, and where the coating layer cannot be thoroughly cleaned after testing, affecting subsequent tests. The proposed device includes a sealed testing shell containing a heating device. A steel plate is laid on the upper surface of the heating device, and the upper surface of the steel plate is coated with a fire-retardant coating. A vertical measuring column is positioned on one side of the steel plate. The testing shell has a transparent observation window, and a thermocouple is connected to the fire-retardant coating. The thermocouple is connected to a temperature display. In the aforementioned prior art, the temperature and thickness of the fire-retardant coating can be simultaneously measured using a thermocouple and measuring column, eliminating cumbersome testing steps. A scraper can be used to clean the fire-retardant coating layer.

[0004] In the aforementioned prior art, the fire-retardant coating applied to the surface of the board after inspection is scraped off by pushing the scraper to move. Although this scraping method can achieve a certain scraping effect, the scraper, the inspection object, and the fire-retardant coating are on the same plane. During the scraping process, the scraper is subject to greater resistance. Pushing the scraper too hard can easily cause the blade to bend, thereby reducing the scraping effect. Utility Model Content

[0005] The purpose of this invention is to provide a fire-retardant coating fire-retardant testing device, which solves the problem in the existing fire-retardant coating fire-retardant testing device that, when scraping off the fire-retardant coating applied to the surface of the object after testing, the scraping method in which the scraper and the coating are on the same plane has greater resistance, which can easily cause the scraper blade to bend and deform, thereby reducing the scraping effect.

[0006] This utility model provides the following technical solution: a fireproof coating fireproof testing device, including a shell, a control box fixedly connected to one end of the shell, and a cabinet door rotatably connected to the end of the shell away from the control box.

The end of the rotating plate away from the fixed plate is fixedly connected to a positioning plate.

[0017] The above technical solution allows for the positioning and restriction of the insertion plate using a positioning plate.

[0018] As a preferred embodiment of the above technical solution, an insert plate is inserted into the inner side of the positioning plate, and a scraper is fixedly connected to the end of the insert plate away from the positioning plate.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] like Figure 1 - Figure 4As shown, this utility model provides a technical solution: a fireproof coating fireproof testing device, including a shell 1, a control box 11 fixedly connected to one end of the shell 1, and a cabinet door 12 rotatably connected to the end of the shell 1 away from the control box 11. A transparent glass plate 13 is installed on the front of the shell 1, and a placement plate 14 is fixedly connected to the inner side of the lower end of the shell 1. A placement groove 15 is opened at the upper end of the placement plate 14, and a flamethrower 16 is fixedly connected to the inner side of the end of the shell 1 away from the control box 11. A scraping assembly 2 is fixedly connected to the upper end of the shell 1, and the scraping assembly 2 includes a motor 21 fixedly connected to the end of the shell 1 near the control box 11. A threaded rod 22 is fixedly connected through the output shaft of the motor 21 through the shell 1, and both ends of the threaded rod 22 are rotatably connected inside the shell 1. A threaded plate 23 is engaged on the outer side of the threaded rod 22. The fireproof coating on the surface of the testing plate can be scraped off at an angle by the scraping assembly 2, which improves the convenience of scraping and reduces the damage to the scraper 217 during the scraping process, thereby increasing the service life of the scraper 217.

[0029] like Figure 4 As shown, a protective cover 24 is fixedly connected to the lower end of the threaded plate 23, and a motor 25 is fixedly connected to the inner side of one end of the protective cover 24. A gear 26 is fixedly connected to the output shaft of the motor 25. After the motor 25 is started, the output shaft drives the gear 26 to rotate, and the gear 26 drives the gear ring 27 and the first electric telescopic rod 28 to rotate and adjust by meshing with the gear ring 27.

[0030] like Figure 4 As shown, one end of the gear 26 is engaged with a toothed ring 27, and a first electric telescopic rod 28 is fixedly connected to the inner side of the toothed ring 27. The upper end of the first electric telescopic rod 28 is rotatably connected to the protective cover 24. The telescopic adjustment of the first electric telescopic rod 28 can drive the fixed plate 29 and the like to move.

[0031] like Figure 2 As shown, a fixed plate 29 is fixedly connected to the lower end of the first electric telescopic rod 28, and a positioning rod 210 is rotatably connected to the inner side of the fixed plate 29. A roller 211 is sleeved on the outer side of the positioning rod 210. When the fixed plate 29 moves, it drives the positioning rod 210 and the roller 211 to move. The roller 211 rolls against the surface of the test plate under the restriction of the positioning rod 210, thereby using the rolling of the roller 211 to assist the movement of the fixed plate 29, etc.

[0032] like Figure 2 As shown, a support plate 212 is fixedly connected to one end of the fixed plate 29, and a second electric telescopic rod 213 is rotatably connected to the upper end of the support plate 212. The operation and extension of the second electric telescopic rod 213 can drive the rotating plate 214 and other components to rotate and adjust under the support of the support plate 212.

[0033] like Figure 2 and Figure 3As shown, the end of the second electric telescopic rod 213 away from the support plate 212 is rotatably connected to a rotating plate 214, and the lower end of the rotating plate 214 is rotatably connected to the fixed plate 29. The end of the rotating plate 214 away from the fixed plate 29 is fixedly connected to a positioning plate 215. The rotating plate 214 drives the positioning plate 215 to rotate, so that the positioning plate 215 synchronously drives the insert plate 216 and the scraper 217 to rotate and adjust.

[0034] like Figure 3 As shown, a plate 216 is inserted into the inner side of the positioning plate 215, and a scraper 217 is fixedly connected to the end of the plate 216 away from the positioning plate 215. A bolt 218 is inserted into one end of the positioning plate 215 and the plate 216. By unscrewing the bolt 218, the scraper 217 can be pulled out of the positioning plate 215 along with the plate 216, thereby replacing the scraper 217.

[0035] Working principle: When using the testing equipment to test the fire resistance of fire-retardant coatings, first open the cabinet door 12, then place the board coated with fire-retardant coating into the placement slot 15 on the placement plate 14, then close the cabinet door 12 and start the flame sprayer 16 to test the fire-retardant coating on the board. After the test is completed, turn off the flame sprayer 16, and then start the first electric telescopic rod 28 through the control box 11. After the first electric telescopic rod 28 is started, the output shaft pushes the fixed plate 29, etc., to move down. During this process, the second electric telescopic rod 213 is started simultaneously. After the second electric telescopic rod 213 is started, it extends under the support of the support plate 212 and pushes the rotating plate 214 to rotate. After the rotating plate 214 rotates, it simultaneously pushes the insert plate 216 and scraper 217 to rotate. When the fixed plate 216 is rotated, the scraper 217, etc., will rotate. When plate 29 moves roller 211 so that the lower end of roller 211 is in contact with the test plate, the first electric telescopic rod 28 is closed. After the second electric telescopic rod 213 extends to its top, one end of scraper 217 is also in contact with the test plate. At this time, motor 21 is started. After motor 21 starts, its output shaft drives threaded rod 22 to rotate. After rotating, threaded rod 22 engages with the threaded plate 23, causing the threaded plate 23 to move the protective cover 24 and the first electric telescopic rod 28. The first electric telescopic rod 28 moves fixed plate 29 and roller 211. During this movement, roller 211 rolls within the restriction of positioning rod 210 while in contact with the test plate. The rolling of roller 211 assists the movement of fixed plate 29. The movement of plate 9 also simultaneously pulls the rotating plate 214 and the positioning plate 215 to move. The positioning plate 215 drives the scraper 217 to move, thereby allowing the scraper 217 to scrape off the fireproof coating on the surface of the test plate. After the threaded plate 23 moves the first electric telescopic rod 28 and other components to one end of the test plate, the first electric telescopic rod 28 is first activated to retract, causing it to move upward. Then, under the protection of the cover 24, the motor 25 is activated. After the motor 25 is activated, the output shaft drives the gear 26 to rotate. The rotation of the gear 26, through meshing with the gear ring 27, drives the gear ring 27 and the first electric telescopic rod 28 to rotate. The rotation of the first electric telescopic rod 28 then drives the fixing plate 29 and other components to rotate 180° for adjustment. After adjustment, the operation is turned off. Motor 25 restarts the first electric telescopic rod 28, extending it to push the fixed plate 29 down, allowing the roller 211 and scraper 217 to fit against the board. Then, the output shaft of motor 21 is controlled to rotate in the opposite direction, causing the threaded plate 23 to move the cover 24 and the first electric telescopic rod 28. The fireproof coating on the board is scraped off again using the scraper 217. After scraping, motor 21 is turned off, and the first electric telescopic rod 28 and the second electric telescopic rod 213 are started to retract, causing the fixed plate 29 and scraper 217 to return to their original positions. Then, the cabinet door 12 is opened to take out the tested board. When the scraper 217 needs to be replaced, the bolt 218 is unscrewed, and the scraper 217 is pulled out of the positioning plate 215 for replacement.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
