Description

Technical Field

[0001] The invention relates to the technical field of spraying devices, and in particular to a spraying device for building fireproof materials. Background Art

[0002] Building fireproof materials refer to materials that can delay the spread of fire and reduce fire losses when a fire occurs. They are widely used in construction, transportation, electricity, chemical industry and other fields, and play an important role in improving the fire safety performance of buildings. In existing steel structure buildings, although steel itself is a non-combustible material, due to its good thermal conductivity and electrical conductivity, when the temperature exceeds a certain limit (such as 300°C), the elastic modulus, yield point and ultimate strength of the steel will drop significantly, and the strain will increase sharply; and when it reaches 600°C, the steel has lost its bearing capacity, which may cause the steel structure to fail rapidly in a fire. Therefore, in order to improve the fire resistance of steel structures, additional fire protection is needed. Among them, spraying fireproof materials is one of the effective means to improve the fire resistance limit of steel structures, block flames and heat transfer, and protect the integrity of steel structures.

[0003] In the prior art, a spraying device is usually used to spray fire retardant coatings on the side walls of steel structures. Depending on the usage scenario, the fire protection requirements are also different. According to the fire protection requirements, fire retardant paints are divided into:

[0004] Ultra-thin fire retardant coating: The coating thickness is generally controlled within 3 mm, which is suitable for occasions with strict requirements on coating thickness, such as building components with high decorative requirements;

[0005] Thin fire retardant coating: The coating thickness is usually between 3 mm and 7 mm, suitable for fire protection of general building components;

[0006] Thick fire retardant coating: The coating thickness is generally above 7 mm but not more than 45 mm. It is suitable for building components with higher fire resistance requirements, such as steel structure columns and beams.

[0007] Due to the influence of the fluidity of the paint itself, the effect of thickness on the solidification method, and the cracking caused by changes in the paint during the solidification process, thick fire retardant coatings are usually achieved by layered spraying. Specifically: the thickness of each layer of spraying is controlled within a certain range (such as 6-10mm) to avoid uneven drying or cracking of the coating due to excessive thickness; when spraying, the distance and angle between the spray gun and the coated surface should be kept moderate (such as 300-500mm) to ensure that the coating is uniform and without sagging; the next layer of spraying can only be carried out after the previous layer of coating is dry until the designed thickness is reached.

[0008] However, in the actual processing process, since the above-mentioned thick fire retardant coating is usually aimed at structures with high load-bearing requirements, such as steel columns and beams, and such structures must have a large weight, it is inconvenient to flip them. During the spraying process, the target needs to be placed on a support frame and the top and both sides of the target are sprayed first, but the bottom of the target cannot be sprayed, and it is necessary to wait for the sprayed part of the target to solidify before turning it over and spraying. Since layered spraying is required and each layer of spraying needs to be turned over, the spraying of steel columns or beams needs to be turned over multiple times, and each turning over needs to wait for the paint sprayed last time to solidify, resulting in low spraying efficiency and high workload. Summary of the invention

[0009] The purpose of the present invention is to provide a building fireproof material spraying device to solve the problem that in the prior art, when spraying fireproof coatings in layers on load-bearing structures with high fireproof requirements, the target needs to be flipped multiple times, resulting in low spraying efficiency and high workload.

[0010] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0011] A building fireproof material spraying device comprises a base, a primer spraying component is arranged on the base, and the primer spraying component is used to spray primer on steel structure; it also comprises a frame, a through slot is arranged on the top of the frame; a paint flake prefabricated component is arranged on the top of the frame, and the paint flake prefabricated component is used to preform fireproof paint into paint flakes; a clamping component is arranged on the top of the base, and the clamping component is used to fix the steel structure; the paint flake prefabricated component comprises a mold base fixedly connected between the inner walls of the through slot, and four mold cavities are arranged on the top of the mold base, and the end face of the mold cavity is an isosceles trapezoid, and the side face and the lower bottom face are clamped The angle is 135°, and the first linear module is fixedly installed on the top of the frame. The movable end of the first linear module is fixedly connected to a moving frame. The first linear module is used to control the moving frame to move in a linear direction. One side of the moving frame is fixedly connected to a plurality of fire retardant paint spraying components. The fire retardant paint spraying components are connected to an external fire retardant paint supply container, and the fire retardant paint spraying components are used to spray fire retardant paint into the mold cavity; a plurality of release agent spraying components are fixedly connected to the side of the moving frame away from the fire retardant paint spraying components, and the release agent spraying components are used to spray release agent into the mold cavity.

[0012] By adopting the above technical scheme, by setting up a paint flake prefabricated component, the fire retardant paint can be prefabricated into fire retardant paint flakes in a form similar to injection molding, and at the same time, the primer is sprayed on the target to be sprayed, so that the spraying of the primer and the fire retardant paint can be carried out simultaneously, and the operation of the fire retardant paint on each side only needs to be turned over once, that is, after applying the adhesive once to the fire retardant paint flakes to be attached, the formed fire retardant paint flakes can be attached to complete the operation, so that there is no need to repeatedly turn over the target when spraying the fire retardant paint in multiple layers, which greatly reduces the difficulty of the operation and improves the operation efficiency.

[0013] A further improvement of the technical solution of the present invention is that: a fixed frame is fixedly connected to the top of the frame, and the fixed frame is an inverted U-shaped structure. A hydraulic cylinder is fixedly connected to the top of the fixed frame, and the piston rod of the hydraulic cylinder extends to the bottom of the fixed frame and is fixedly connected to a lifting plate. Two first pressure plates are symmetrically fixedly connected to the bottom of the lifting plate, and the first pressure plates match the shapes of two mold cavities located on both sides; a plurality of sliding rods are slidably connected to the top of the lifting plate, and iron blocks are fixedly connected to the top of the sliding rods. The bottoms of the sliding rods extend to the bottom of the lifting plate and are fixedly connected to second pressure plates between them, and the second pressure plates match the shapes of two mold cavities located in the central part. A first spring is sleeved on the outside of the sliding rod and located below the lifting plate. A plurality of magnets are fixedly connected to the top of the lifting plate, and the magnets correspond to the iron blocks one by one and are used in combination.

[0014] By adopting the above technical solution, a layer of tin foil is placed in the mold base, and a release agent spraying component is provided to facilitate spraying the release agent on the mold base (including the inner wall) and the tin foil, thereby facilitating the peeling of the paint flakes from the mold base.

[0015] A further improvement of the technical solution of the present invention is that: the lower end of the mold cavity passes through the bottom of the mold base and is connected to the inside of the frame, the top of the inner wall of the frame is symmetrically hinged with two bottom plates, the top of the inner wall of the frame is symmetrically fixedly connected with an electric telescopic rod, the output end of the electric telescopic rod is fixedly connected with a wedge block, the two corners on the side of the wedge block with the inclined surface are both rounded corners, the top of the wedge block is in contact with the top of the inner wall of the frame, and the wedge block is in contact with the bottom plate; a grinding component is provided inside the frame, and the grinding component is used to grind the bottom plate of the prefabricated paint flakes; the side wall of the bottom plate is provided with an expansion groove matching the shape of the bottom surface of the mold cavity.

[0016] By adopting the above technical scheme, the mold cavity is set as a bottomless structure, and a reversible bottom plate is set to serve as the bottom of the mold cavity. At the same time, an expansion groove is set on the bottom plate to form a chamber for shaping the paint flake together with the mold cavity. Therefore, after shaping, the paint flake structure can be an isosceles trapezoid with a smaller bottom surface with a rectangular protrusion, which is used to compensate for the defects produced in the above-mentioned peeling process. A grinding component is provided, which can turn over the bottom plate after the paint flake is formed, and grind the protrusion on the paint flake until the protrusion is completely ground off, thereby producing a rough bottom surface, thereby facilitating the attachment of adhesive to improve the stability of bonding.

[0017] A further improvement of the technical solution of the present invention is that the grinding component includes a second linear module fixedly installed on the top of the inner wall of the frame, the movable end of the second linear module is fixedly connected to a slide, the second linear module is used to control the slide to slide along a straight line, a roller is rotatably connected to the slide, grinding rollers are symmetrically fixedly connected at both ends of the roller, a gear is fixedly connected to the outer side of the roller, a rack is fixedly connected to the top of the inner wall of the frame, and the rack is meshingly connected to the gear.

[0018] By adopting the above technical solution, the second linear module is controlled to work, so that the slide, roller and grinding roller move in a straight line. During the process, the gear moves linearly relative to the rack. Since the two are engaged, the gear rotates around the center during the movement and drives the roller and grinding roller to rotate, thereby grinding the bottom of the paint flakes until the protruding parts generated by the expansion groove part in the above process are ground off and the grinding surface becomes rough.

[0019] A further improvement of the technical solution of the present invention is that a rough surface is provided on the side of the bottom plate away from the expansion groove, a rough surface is also provided on the rounded corner of the wedge block at the lower end, and a collection box is placed inside the frame for collecting grinding debris.

[0020] By adopting the above technical solution, during the grinding process, the wedge block is not completely retracted, so that the base plate is still in an inclined state, so the debris produced by grinding will move toward the central position along the inclined base plate and fall into the collection box. After the grinding is completed, the electric telescopic rod is controlled to be completely retracted, and the extension and retraction action is repeated for a small amount of stroke, so that the base plate vibrates, thereby shaking off the debris. At the same time, by providing mutually matching rough surfaces on the wedge block and the base plate, during the repeated action of the above-mentioned electric telescopic rod, the rough surface on the wedge block contacts the rough surface on the base plate and slides relatively, thereby generating relatively high-frequency shaking, thereby improving the efficiency of shaking off the debris.

[0021] A further improvement of the technical solution of the present invention is that the bottom plates of the first pressing plate and the second pressing plate are both provided with a plurality of suction holes, the suction holes are connected to the external air pump through pipes, and an electromagnetic valve is provided on the pipes connecting the suction holes and the air pump.

[0022] By adopting the above technical solution, suction holes are arranged on the first pressing plate and the second pressing plate, and connected to an external air pump, negative pressure is provided to the suction holes to absorb paint flakes, so that the paint flakes can be used as a material taking arm.

[0023] A further improvement of the technical solution of the present invention is that the clamping component includes a fixed side plate fixedly connected to the top of the base, an adjusting groove is opened on the top of the base, a first screw is rotatably connected between the two sides of the inner wall of the adjusting groove, one end of the first screw extends to the outside of the base and is fixedly connected to the turning handle, the outer side of the first screw is threadedly connected to a slider, the top of the slider is fixedly connected to a movable side plate, the movable side plate is slidably connected to the base, the side of the movable side plate close to the fixed side plate is rotatably connected to a chuck, four strip grooves are opened on one end surface of the chuck, one side of the inner wall of the strip groove is threadedly connected to a second screw, one end of the second screw is rotatably connected to a clamping block, the clamping block is slidably connected to the strip groove, the end of the second screw away from the clamping block extends to the outside of the chuck and is fixedly connected to the turning handle, the clamping block has a T-shaped structure, and a rounded corner is provided on one side of the clamping block.

[0024] By adopting the above technical solution, the handle located at the bottom of the chuck is rotated to rotate the corresponding second screw, so that the block on the second screw moves upward until it contacts the bottom of the steel structure, and the block can provide support. At this time, the primer spraying component can be used to spray the three sides of the steel structure except the bottom surface; when flipping, ensure that the four blocks are in contact with the steel structure, and after the flipping is completed, control the block on the side that needs to be processed to stay away from the steel structure.

[0025] A further improvement of the technical solution of the present invention is that one end of the central axis of the chuck close to the fixed side plate passes through the other side of the fixed side plate and is fixedly connected to a turning handle, four insertion holes are opened on the side of the fixed side plate away from the chuck, one side of the turning handle is fixedly connected to a U-shaped plate, one side of the U-shaped plate is slidably connected to an insertion rod, one end of the insertion rod extends to the outside of the U-shaped plate and is fixedly connected to a handle, the end of the insertion rod away from the handle passes through the turning handle and is plugged into the insertion hole, the insertion rod is slidably connected to the turning handle, the outer side of the insertion rod is fixedly connected to a pad, and the outer side of the insertion rod is covered with a second spring.

[0026] By adopting the above technical solution, when the steel structure is blocked on all sides by the blocks, the handle is pulled to drive the insertion rod to leave the socket and drive the pad to compress the second spring, so that the handle can be rotated and the chuck can be driven to flip synchronously to realize the flipping of the steel structure. When the flipping angle is a multiple of the right angle, the insertion rod is facing one of the sockets, so that by releasing the handle, the insertion rod can be inserted into the socket under the rebound action of the second spring.

[0027] A further improvement of the technical solution of the present invention is that two auxiliary support frames are fixedly connected to the top of the base, the auxiliary support frames are configured as liftable scissor support structures, and the tops of the auxiliary support frames are fixedly connected to a carrier plate.

[0028] By adopting the above technical solution, since the steel structure to be painted is of large mass, it is troublesome to lift it manually and then fix it to the clamping parts. By providing an auxiliary support frame that can be raised and lowered, it is convenient to lift the steel structure before using the clamping parts to fix the steel structure. In this way, there is no need for the handling personnel to lift and wait for the clamping parts to be fixed. The clamping process only requires fine-tuning of the auxiliary support frame, thereby reducing the difficulty of operation.

[0029] The steps for using the building fireproof material spraying device are as follows:

[0030] S1. Place the steel structure to be sprayed with fire retardant paint on the clamping component, and use the clamping component to support the bottom of the steel structure. Use the primer spraying component to evenly spray the primer on the three sides of the steel structure except the bottom until the three sides are completely covered, and let it stand until the primer is air-dried;

[0031] By setting up a paint flake prefabricated component, the fire retardant paint can be prefabricated into fire retardant paint flakes in a form similar to injection molding, and at the same time, the primer is sprayed on the target to be sprayed, so that the spraying of the primer and the fire retardant paint can be carried out simultaneously, and the operation of the fire retardant paint on each side only needs to be turned over once, that is, after applying the adhesive once to the target to be attached, the formed fire retardant paint flakes can be attached to complete the operation, so that there is no need to repeatedly turn over the target when spraying the fire retardant paint in multiple layers, which greatly reduces the difficulty of operation and improves the operation efficiency.

[0032] S2, using a mold release agent spraying component to evenly spray the mold release agent into the mold base, and after the spraying is completed, covering the mold base with tin foil;

[0033] In terms of technology, a layer of tin foil is placed in the mold base, and a release agent spraying component is provided to facilitate spraying the release agent on the mold base (including the inner wall) and the tin foil, thereby facilitating the peeling of the paint flakes from the mold base.

[0034] S3, pressing the tin foil downwards by means of the first pressing plate and the second pressing plate until it is pressed into the mold cavity to form a groove and be shaped, and using a release agent spraying component to evenly spray a release agent on the tin foil;

[0035] S4, using the paint flake prefabricated component to spray fire retardant paint on the grooves on the tinfoil paper multiple times, each time spraying, waiting for the fire retardant paint sprayed last time to solidify and completely cover the fire retardant paint sprayed last time, until the target thickness is reached, that is, four paint flakes made of multiple layers of fire retardant paint are obtained;

[0036] Spraying is also used for the prefabrication of paint chips to restore the spraying effect as much as possible, which can reduce the generation of bubbles compared to direct injection.

[0037] S5. Tear off the tin foil and grind the peeled side of the tin foil until a rough surface is produced;

[0038] The raised portion on the paint chip is sanded until the raised portion is completely removed and a rough bottom surface is generated to facilitate the adhesion of the adhesive and improve the stability of the bonding.

[0039] S6. Apply adhesive to the upward side of the steel structure, align the rough side of the paint sheet with the side coated with adhesive, and then bond them together, and wait for the adhesive to solidify;

[0040] S7, using the clamping parts to flip the steel structure 90 degrees, spray the primer on the side that has not been sprayed with primer, and repeat step S6 and the above flipping operation until paint chips are pasted on all four sides of the steel structure;

[0041] The primer spraying operation is carried out simultaneously with the application of adhesive and waiting for the glue to solidify, which reduces the waiting time.

[0042] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0043] 1. The present invention can prefabricate fire retardant paint flakes by arranging a paint flake prefabricated component in a manner similar to injection molding, and at the same time spray primer on the target to be sprayed, so that the spraying of primer and fire retardant paint can be carried out simultaneously, and the operation of the fire retardant paint on each side only needs to be turned over once, that is, after applying the adhesive once to the target to be attached, the formed fire retardant paint flakes can be attached to complete the operation, so that when performing multi-layer spraying of fire retardant paint, there is no need to repeatedly turn over the target, which greatly reduces the difficulty of operation and improves the operation efficiency.

[0044] 2. The present invention places a layer of tin foil in the mold base before prefabricating the paint flakes, and provides a release agent spraying component to facilitate spraying the release agent on the mold base (including the inner wall) and the tin foil, thereby facilitating the peeling of the paint flakes from the mold base. The peeling of the tin foil and the paint flakes can be performed in a narrow space, and rubbing, grinding and other means can be used during the peeling process, thereby facilitating the separation of the paint flakes.

[0045] 3. The present invention sets the mold cavity as a bottomless structure, and sets a reversible bottom plate to serve as the bottom of the mold cavity. At the same time, an expansion groove is set on the bottom plate to form a chamber for shaping the paint flake together with the mold cavity, so that after shaping, the paint flake structure can be an isosceles trapezoid with a smaller bottom surface with a rectangular protrusion, which is used to compensate for the defects produced in the above-mentioned peeling process. A grinding component is also set, which can turn over the bottom plate after the paint flake is formed, and grind the protrusion on the paint flake until the protrusion is completely ground off, thereby producing a rough bottom surface, thereby facilitating the attachment of adhesive to improve the stability of bonding.

[0046] 4. The present invention provides mutually cooperating rough surfaces on the wedge block and the bottom plate. Specifically, the bottom plate is still in an inclined state during the grinding process, so the grinding debris will move toward the central position along the inclined bottom plate and fall into the collection box. After the grinding is completed, the electric telescopic rod is controlled to be completely retracted, and the extension and retraction actions are repeated for a small amount of stroke, so that the bottom plate vibrates, thereby shaking off the debris. At the same time, by providing mutually cooperating rough surfaces on the wedge block and the bottom plate, during the repeated action of the above-mentioned electric telescopic rod, the rough surface on the wedge block contacts the rough surface on the bottom plate and slides relatively, thereby generating relatively high-frequency shaking, thereby improving the efficiency of shaking off the debris.

[0047] 5. The present invention provides clamping components with four points for clamping. When spraying the primer, the steel structure only needs to be supported by the clamping blocks located below. When flipping is required, the steel structure is clamped by the clamping blocks on all sides at the same time. The steel structure can be flipped by rotating the chuck, and manual handling and flipping are not required, which greatly facilitates the actual operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] The present invention is further described in detail below in conjunction with embodiments:

[0066] Example 1

[0067] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a building fireproof material spraying device, including a base 2, on which a primer spraying component 3 is arranged, and the primer spraying component 3 is used to spray primer on the steel structure; it also includes a frame 1, and the top of the frame 1 is provided with a through groove; the top of the frame 1 is provided with a paint flake prefabricated component, and the paint flake prefabricated component is used to preform fireproof paint into paint flakes; the top of the base 2 is provided with a clamping component, and the clamping component is used to fix the steel structure; the paint flake prefabricated component includes a mold base 11 fixedly connected between the inner walls of the through groove, and the top of the mold base 11 is provided with four mold cavities 12, and the end face of the mold cavity 12 is an isosceles trapezoid, and the side surface is connected to the lower bottom The surface angle is 135°, and the first linear module 7 is fixedly installed on the top of the frame 1. The movable end of the first linear module 7 is fixedly connected to a movable frame 8. The first linear module 7 is used to control the movable frame 8 to move along a linear direction. One side of the movable frame 8 is fixedly connected to a plurality of fire retardant paint spraying components 10. The fire retardant paint spraying components 10 are connected to an external fire retardant paint supply container. The fire retardant paint spraying components 10 are used to spray fire retardant paint into the mold cavity 12; the side of the movable frame 8 away from the fire retardant paint spraying components 10 is fixedly connected to a plurality of release agent spraying components 9. The release agent spraying components 9 are used to spray release agent into the mold cavity 12.

[0068] In this embodiment, by providing a paint flake prefabricated component, the fire retardant paint can be prefabricated into fire retardant paint flakes in a form similar to injection molding, and at the same time, the primer is sprayed on the target to be sprayed, so that the spraying of the primer and the fire retardant paint can be carried out simultaneously, and the operation of the fire retardant paint on each side only needs to be turned over once, that is, after applying the adhesive once to the target to be attached, the formed fire retardant paint flake can be attached to complete the operation, so that when performing multi-layer spraying of the fire retardant paint, there is no need to repeatedly turn over the target, which greatly reduces the difficulty of the operation and improves the operation efficiency;

[0069] Among them, spraying is also used for the prefabrication of paint chips to restore the spraying effect as much as possible, which can reduce the generation of bubbles compared to direct injection.

[0070] Example 2

[0071] like Figure 1 and Figure 8 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, a fixing frame 4 is fixedly connected to the top of the frame 1, and the fixing frame 4 is an inverted U-shaped structure. A hydraulic cylinder 5 is fixedly connected to the top of the fixing frame 4, and the piston rod of the hydraulic cylinder 5 extends to the bottom of the fixing frame 4 and is fixedly connected to a lifting plate 6. The bottom of the lifting plate 6 is symmetrically fixedly connected with two first pressing plates 13, and the first pressing plates 13 match the shapes of the two mold cavities 12 located on both sides; a plurality of sliding rods 14 are slidably connected to the top of the lifting plate 6, and an iron block 16 is fixedly connected to the top of the sliding rods 14. The bottoms of the sliding rods 14 extend to the bottom of the lifting plate 6 and are fixedly connected with second pressing plates 15, and the second pressing plates 15 match the shapes of the two mold cavities 12 located in the central part. A first spring 18 is sleeved on the outer side of the sliding rods 14 and located below the lifting plate 6. A plurality of magnets 17 are fixedly connected to the top of the lifting plate 6, and the magnets 17 correspond to the iron blocks 16 one by one and are used in conjunction with each other.

[0072] Since the fire retardant coating itself has strong adhesion, it usually adheres firmly to the target after solidification and is not easy to peel off. If it is forcibly torn off, it is easy to tear the paint flakes and cause damage to the paint flakes;

[0073] In this embodiment, a layer of tin foil is placed in the mold base 11, and a release agent spraying component 9 is provided to spray the release agent on the mold base 11 (including the inner wall) and the tin foil, so that the paint flakes can be easily peeled off from the mold base 11.

[0074] Specifically, tinfoil is placed on the mold base 11, and the hydraulic cylinder 5 is controlled to move downward. During the movement, the second pressing plate 15 contacts the tinfoil. In the initial stage, since the second pressing plate 15 only contacts the tinfoil and is not supported by the mold base 11, the iron block 16 will not be separated from the magnet 17. The magnetic force of the magnet 17 on the iron block 16 can provide stable support for the second pressing plate 15 to press the tinfoil in advance, and as the lifting frame continues to move downward, the second pressing plate 15 presses the tinfoil into the mold cavity 12 and forms a structure in the shape of the mold cavity 12 (and the chamber formed by the expansion groove 21). Thereafter, the lifting frame continues to press downward to separate the magnet 17 from the iron block 16, and the spring is compressed until the first pressing plate 13 contacts and presses down the tinfoil, so that the tinfoil is pressed into the mold cavity 12 on both sides, and corresponding grooves are generated on the tinfoil for shaping the paint flakes.

[0075] Example 3

[0076] like Figure 3 , Figure 4 and Figure 6 As shown, on the basis of Example 2, the present invention provides a technical solution: preferably, the lower end of the mold cavity 12 passes through the bottom of the mold base 11 and communicates with the interior of the frame 1, and the top of the inner wall of the frame 1 is symmetrically hinged with two bottom plates 20, and the top of the inner wall of the frame 1 is symmetrically fixedly connected with an electric telescopic rod 46, and the output end of the electric telescopic rod 46 is fixedly connected with a wedge block 22, and the two corners of the inclined side of the wedge block 22 are both rounded corners 39, the top of the wedge block 22 is in contact with the top of the inner wall of the frame 1, and the wedge block 22 is in contact with the bottom plate 20; a grinding component is provided inside the frame 1, and the grinding component is used to grind the bottom plate 20 of the prefabricated paint flakes; the side wall of the bottom plate 20 is provided with an expansion groove 21 matching the shape of the bottom surface of the mold cavity 12.

[0077] Although the use of the above-mentioned prefabricated paint flakes can reduce the number of times that the steel structure needs to be turned over during the spraying of fire retardant paint, since the fire retardant paint itself has a very strong adhesion ability, that is, after being sprayed to the target and solidified, it is usually difficult to peel off. In the above process, in order to facilitate peeling, tin foil is placed as a cushion layer to separate the mold cavity 12 and the paint flakes, and at the same time, a release agent is sprayed to reduce the adhesion between the paint flakes and the mold cavity 12 and between the paint flakes and the tin foil. In addition, the surface of the tin foil itself is smooth, so it is easier to peel off the paint flakes after they are formed. However, this will also cause the layer of the paint flakes and the tin foil to become smooth after forming, which is not easy to adhere to the adhesive, making it difficult to attach stably. In addition, since the actual processing situation is not ideal, in the process of peeling the tin foil, it is inevitable that some areas will be damaged during the peeling, resulting in partial defects in some areas of the paint flakes, thereby affecting the attachment effect;

[0078] In this embodiment, the mold cavity 12 is set as a bottomless structure, and a reversible bottom plate 20 is set to serve as the bottom of the mold cavity 12. At the same time, an expansion groove 21 is set on the bottom plate 20 to form a chamber for shaping the paint flake together with the mold cavity 12. Therefore, after shaping, the paint flake structure can be an isosceles trapezoid with a smaller bottom surface with a rectangular protrusion, which is used to compensate for the defects produced in the above-mentioned peeling process. A grinding component is provided, which can turn over the bottom plate 20 after the paint flake is formed, and grind the protrusion on the paint flake until the protrusion is completely ground off, thereby producing a rough bottom surface, thereby facilitating the attachment of adhesive to improve the stability of bonding.

[0079] like Figure 3 and Figure 4 As shown, preferably, the grinding component includes a second linear module 24 fixedly mounted on the top of the inner wall of the frame 1, the movable end of the second linear module 24 is fixedly connected to a slide 25, the second linear module 24 is used to control the slide 25 to slide along a straight line, a roller 27 is rotatably connected to the slide 25, grinding rollers 29 are symmetrically fixedly connected at both ends of the roller 27, a gear 28 is fixedly connected to the outer side of the roller 27, a rack 26 is fixedly connected to the top of the inner wall of the frame 1, and the rack 26 is meshingly connected to the gear 28.

[0080] In this embodiment, the second linear module 24 is controlled to work so that the slide 25, the roller 27 and the grinding roller 29 move in a straight line. During the process, the gear 28 moves linearly relative to the rack 26. Since the two are engaged, the gear 28 rotates around the center during the movement and drives the roller 27 and the grinding roller 29 to rotate, thereby grinding the bottom of the paint flake until the protruding part generated by the expansion groove 21 in the above process is ground off and the grinding surface becomes rough.

[0081] Example 4

[0082] like Figure 4 and Fig.11 As shown, based on Example 3, the present invention provides a technical solution: preferably, a rough surface 23 is provided on the side of the base plate 20 away from the expansion groove 21, and a rough surface 23 is also provided at the rounded corner 39 at the lower end of the wedge block 22, and a collection box is placed inside the frame 1, and the collection box is used to collect grinding debris.

[0083] During the grinding process, the bottom plate 20 is partially opened at the beginning to act as a guide plate to guide the grinding debris into the collection box. However, since there is an expansion groove 21 on the bottom plate 20, it is inevitable that debris will remain in the expansion groove 21 during the grinding process, thereby affecting subsequent processing.

[0084] In this embodiment, during the grinding process, the wedge block 22 is not completely retracted, so that the base plate 20 is still in an inclined state, so that the debris produced by grinding will move toward the central position along the inclined base plate 20 and fall into the collection box. After the grinding is completed, the electric telescopic rod 46 is controlled to be completely retracted, and the extension and retraction action is repeated for a small amount of stroke, so that the base plate 20 shakes, thereby shaking off the debris. At the same time, by providing mutually matching rough surfaces 23 on the wedge block 22 and the base plate 20, during the repeated action of the above-mentioned electric telescopic rod 46, the rough surface 23 on the wedge block 22 contacts the rough surface 23 on the base plate 20 and slides relatively, thereby generating relatively high-frequency shaking, thereby improving the efficiency of shaking off the debris.

[0085] like Figure 3 and Fig.13 As shown, preferably, the bottom plates 20 of the first pressing plate 13 and the second pressing plate 15 are each provided with a plurality of suction holes 19, the suction holes 19 are connected to an external air pump through a pipeline, and a solenoid valve is provided on the pipeline connecting the suction holes 19 and the air pump.

[0086] After the paint flakes are formed, they need to be taken out. In order to ensure the integrity of the paint flakes and reduce the damage caused by pulling when taking them out, it is necessary to take the paint flakes at multiple points in the axial direction (the direction with the longest length). However, due to the installation position restrictions of the equipment, it is difficult to set up a special material taking arm.

[0087] In this embodiment, suction holes 19 are provided on the first pressing plate 13 and the second pressing plate 15 and connected to an external air pump, and negative pressure is provided to the suction holes 19 to absorb paint flakes, so that the paint flakes can be used as a material taking arm.

[0088] Example 5

[0089] like Fig. 9 and Fig.12 As shown, on the basis of Example 4, the present invention provides a technical solution: preferably, the clamping component includes a fixed side plate 30 fixedly connected to the top of the base 2, an adjusting groove 32 is opened on the top of the base 2, a first screw 33 is rotatably connected between the two sides of the inner wall of the adjusting groove 32, one end of the first screw 33 extends to the outside of the base 2 and is fixedly connected to the handle, the outer side of the first screw 33 is threadedly connected to a slider 34, the top of the slider 34 is fixedly connected to a movable side plate 31, and the movable side plate 31 is slidably connected to the base 2 The movable side plate 31 and the fixed side plate 30 are rotatably connected to a chuck 35 on one side, and four strip grooves 36 are provided on one end surface of the chuck 35. A second screw 37 is threadedly connected to one side of the inner wall of the strip groove 36. A clamping block 38 is rotatably connected to one end of the second screw 37. The clamping block 38 is slidably connected to the strip groove 36. One end of the second screw 37 away from the clamping block 38 extends to the outside of the chuck 35 and is fixedly connected to a turning handle. The clamping block 38 is a T-shaped structure, and a rounded corner 39 is provided on one side of the clamping block 38.

[0090] In this embodiment, the turning handle on the base 2 is turned to drive the first screw rod 33 to rotate, so that the slider 34 slides along the adjustment slot 32, the movable side plate 31 moves in the direction close to the steel structure, and pushes the steel structure to move closer to the fixed side plate 30, until the two ends of the steel structure are respectively in contact with the two chucks 35, and then the turning handle located at the bottom of the chuck 35 is turned to rotate the corresponding second screw rod 37, so that the block 38 on the second screw rod 37 moves upward until it contacts the bottom of the steel structure. At this time, the block 38 provides support, and can control the auxiliary support frame 48 to descend so that it no longer provides support, and at the same time will not hinder the turning of the steel structure. At this time, the primer spraying component 3 can be used to spray the primer on the three sides of the steel structure except the bottom surface;

[0091] When flipping, ensure that the four blocks 38 are in contact with the steel structure, and after the flipping is completed, control the block 38 on the side that needs to be processed to be away from the steel structure.

[0092] like Fig.10 and Fig.15 As shown, preferably, one end of the central axis of the chuck 35 close to the fixed side plate 30 passes through the other side of the fixed side plate 30 and is fixedly connected to a turning handle 41, and four insertion holes 40 are opened on the side of the fixed side plate 30 away from the chuck 35, and a U-shaped plate 42 is fixedly connected to one side of the turning handle 41, and a plug rod 43 is slidably connected to one side of the U-shaped plate 42, and one end of the plug rod 43 extends to the outside of the U-shaped plate 42 and is fixedly connected to a handle 47, and the end of the plug rod 43 away from the handle 47 passes through the turning handle 41 and is plugged into the insertion hole 40, the plug rod 43 is slidably connected to the turning handle 41, and a pad 45 is fixedly connected to the outer side of the plug rod 43, and a second spring 44 is sleeved on the outer side of the plug rod 43.

[0093] In this embodiment, when the steel structure is resisted by the blocking blocks 38 on all sides, the handle 47 is pulled to drive the insertion rod 43 to leave the insertion hole 40, and drive the pad 45 to compress the second spring 44, so that the handle 41 can be rotated and the chuck 35 can be synchronously flipped to realize the flipping of the steel structure. When the flipping angle is a multiple of the right angle, the insertion rod 43 is facing one of the insertion holes 40, so that the handle 47 can be released to allow the insertion rod 43 to be inserted into the insertion hole 40 under the rebound action of the second spring 44.

[0094] like Figure 1 and Figure 6 As shown, preferably, two auxiliary support frames 48 are fixedly connected to the top of the base 2 , the auxiliary support frames 48 are configured as a liftable scissor support structure, and a carrier plate 49 is fixedly connected to the top of the auxiliary support frames 48 .

[0095] In this embodiment, since the steel structure to be painted is of large mass, it is troublesome to lift it manually and then fix it to the clamping components. By providing an auxiliary support frame 48 that can be raised and lowered, it is convenient to lift the steel structure before using the clamping components to fix the steel structure. In this way, there is no need for the processing personnel to lift and wait for the clamping components to be fixed. The clamping process only requires fine-tuning of the auxiliary support frame 48, thereby reducing the difficulty of operation.

[0096] The steps for using the building fireproof material spraying device are as follows:

[0097] S1. Place the steel structure to be sprayed with fire retardant paint on the clamping component, and use the clamping component to support the bottom of the steel structure. Use the primer spraying component 3 to evenly spray the primer on the three sides of the steel structure except the bottom until the three sides are completely covered, and let it stand until the primer is air-dried;

[0098] By setting up a paint flake prefabricated component, the fire retardant paint can be prefabricated into fire retardant paint flakes in a form similar to injection molding, and at the same time, the primer is sprayed on the target to be sprayed, so that the spraying of the primer and the fire retardant paint can be carried out simultaneously, and the operation of the fire retardant paint on each side only needs to be turned over once, that is, after applying the adhesive once to the target to be attached, the formed fire retardant paint flakes can be attached to complete the operation, so that there is no need to repeatedly turn over the target when spraying the fire retardant paint in multiple layers, which greatly reduces the difficulty of operation and improves the operation efficiency.

[0099] S2, using the release agent spraying component 9 to evenly spray the release agent into the mold base 11, and after the spraying is completed, covering the mold base 11 with tin foil;

[0100] In terms of technology, a layer of tin foil is placed in the mold base 11 and a release agent spraying component 9 is provided to spray the release agent on the mold base 11 (including the inner wall) and the tin foil, thereby facilitating the peeling of the paint sheet from the mold base 11 .

[0101] S3, pressing the tin foil downwards by the first pressing plate 13 and the second pressing plate 15 until it is pressed into the mold cavity 12 to form a groove and be shaped, and using the release agent spraying component 9 to evenly spray the release agent on the tin foil;

[0102] S4, using the paint flake prefabricated component to spray fire retardant paint on the grooves on the tinfoil paper multiple times, each time spraying, waiting for the fire retardant paint sprayed last time to solidify and completely cover the fire retardant paint sprayed last time, until the target thickness is reached, that is, four paint flakes made of multiple layers of fire retardant paint are obtained;

[0103] Spraying is also used for the prefabrication of paint chips to restore the spraying effect as much as possible, which can reduce the generation of bubbles compared to direct injection.

[0104] S5, tearing off the tin foil, and grinding one side of the peeled tin foil until a rough surface 23 is generated;

[0105] The raised portion on the paint chip is sanded until the raised portion is completely removed and a rough bottom surface is generated to facilitate the adhesion of the adhesive and improve the stability of the bonding.

[0106] S6, applying adhesive to the upward side of the steel structure, aligning the side of the paint sheet with the rough surface 23 with the side coated with adhesive, and then bonding them, and waiting for the adhesive to solidify;

[0107] S7, using the clamping parts to flip the steel structure 90 degrees, spray the primer on the side that has not been sprayed with primer, and repeat step S6 and the above flipping operation until paint chips are pasted on all four sides of the steel structure;

[0108] The primer spraying operation is carried out simultaneously with the application of adhesive and waiting for the glue to solidify, which reduces the waiting time.

[0109] The working principle of the building fireproof material spraying device is specifically described below.

[0110] like Figure 1-Figure 15 As shown, before the paint chips are prefabricated, when the slide 25 is located at one end of the second linear module 24, the electric telescopic rod 46 is controlled to work to push the wedge block 22 to move, so that the inclined surface of the wedge block 22 is used to push the bottom plate 20 to flip until the bottom plate 20 flips to a horizontal state. In this state, the bottom plate 20 is tightly fitted with the bottom plate 20 of the mold base 11, so that each mold cavity 12 and the bottom plate 20 together form a plurality of independent chambers.

[0111] Use the release agent spraying component 9 to evenly spray the release agent into the mold base 11 until the mold assembly is completely covered with the release agent;

[0112] The tinfoil is placed on the die base 11, and the hydraulic cylinder 5 is controlled to work to make the lifting frame move downward. During the movement, the second pressing plate 15 contacts the tinfoil. In the initial stage, since the second pressing plate 15 only contacts the tinfoil and is not supported by the die base 11, the iron block 16 and the magnet 17 will not be separated. As the lifting frame continues to move downward, the second pressing plate 15 presses the tinfoil into the die cavity 12 and forms a structure in the shape of the die cavity 12 (and the chamber formed by the expansion groove 21). Thereafter, the lifting frame continues to press downward to separate the magnet 17 from the iron block 16, and the spring pressure The tin foil is shrunk until the first pressing plate 13 contacts and presses down the tin foil, so that the tin foil is pressed into the mold cavity 12 on both sides, and corresponding grooves are generated on the tin foil. After standing for a few seconds, the lifting frame is controlled to rise, so that the first pressing plate 13 and the second pressing plate 15 are separated from the tin foil. This process can be carried out by blowing air to the suction hole 19 through an external air pump to cause the tin foil to separate from the first pressing plate 13 and the second pressing plate 15, thereby preventing the tin foil from being lifted up by the first pressing plate 13 and the second pressing plate 15, and using the release agent spraying component 9 to evenly spray the release agent on the tin foil.

[0113] The first linear module 7 is controlled to work to make the movable frame 8 move. During the process, the fire retardant paint is sprayed to the groove on the tinfoil through the paint sheet prefabricated component. The spraying process is divided into multiple times. Each spraying waits for the fire retardant paint sprayed last time to solidify, and the newly sprayed fire retardant paint completely covers the fire retardant paint sprayed last time. The spraying is repeated until the target thickness is reached, that is, four paint sheets made of multiple layers of fire retardant paint are obtained;

[0114] It should be further explained that, since the above process needs to wait for the fire retardant paint to solidify for multiple times, this process can simultaneously carry out the processing operation of the steel structure, so that the spraying of the primer and the spraying of the fire retardant paint on the steel structure can be carried out simultaneously, thereby improving the efficiency of the spraying process. Specifically, the steel structure to be sprayed with fire retardant paint is placed on the clamping component, and the bottom of the steel structure is supported by the clamping component. The primer is evenly sprayed on the three sides of the steel structure except the bottom through the primer spraying component 3 until the above three sides are completely covered, and then left to stand until the primer is air-dried.

[0115] After the paint flakes are completely solidified, the hydraulic cylinder 5 is controlled to work, driving the lifting plate 6 to move downward until the bottoms of the first pressing plate 13 and the second pressing plate 15 are in contact with the paint flakes, and the suction hole 19 is provided with negative pressure by an external air pump, so that the suction hole 19 sucks the paint flakes, and the first pressing plate 13 and the second pressing plate 15 are controlled to rise by the hydraulic cylinder 5, and the paint flakes and tin foil are driven to rise synchronously (in this process, the second pressing plate 15 moves downward in the area under the action of the elastic force of the first spring 18 and the magnet 17 on the iron block 16, and part of the tin foil is automatically peeled off), and the operator manually tears off the tin foil.

[0116] After completing the above operations, the first pressing plate 13 and the second pressing plate 15 are controlled to move downward and the paint flakes are returned to the mold cavity 12, and the first pressing plate 13 and the second pressing plate 15 are used to press them, and the electric telescopic rod 46 is controlled to be retracted, and the wedge block 22 is driven to be retracted until the top is no longer in contact with the bottom plate 20. After the bottom plate 20 loses support, one side flips downward to an inclined state.

[0117] The second linear module 24 is controlled to work, so that the slide 25, the roller 27 and the grinding roller 29 move in a straight line. During the process, the gear 28 moves linearly relative to the rack 26. Since the two are meshed, the gear 28 rotates around the center during the activity, and drives the roller 27 and the grinding roller 29 to rotate, so as to grind the bottom of the paint flake until the protruding part generated by the expansion groove 21 in the above process is polished off, and the grinding surface becomes rough at the same time; in the above process, the wedge block 22 is not completely retracted, so that the bottom plate 20 is still in an inclined state, so the grinding debris will all move toward the central position along the inclined bottom plate 20 and fall into the collection box. After the grinding is completed, the electric telescopic rod 46 is controlled to be fully retracted, and the extension and retraction actions are repeated for a small amount of stroke, so that the bottom plate 20 shakes, thereby shaking off the debris. In this process, the rough surface 23 on the wedge block 22 contacts the rough surface 23 on the bottom plate 20 and slides relatively, thereby generating relatively high-frequency shaking, which improves the efficiency of shaking off the debris.

[0118] Primer spraying and adhesive coating process for steel structure: by controlling the auxiliary support frame 48 to rise to the same height as the center of the chucks 35 on both sides, the steel structure is placed on the carrier plate 49, and the handles on the chucks 35 are rotated to drive the second screw 37 to rotate. The second screw 37 is threadedly connected with the chuck 35 (the strip groove 36), so it will also move axially during the rotation process, and drive the clamping block 38 to move to the side away from the center of the chuck 35;

[0119] The turning handle on the base 2 is turned to drive the first screw rod 33 to rotate, so that the slider 34 slides along the adjustment slot 32, the movable side plate 31 moves in the direction close to the steel structure, and pushes the steel structure to move closer to the fixed side plate 30 until the two ends of the steel structure are respectively in contact with the two chucks 35. At this time, the turning handle located at the bottom of the chuck 35 is turned again to rotate the corresponding second screw rod 37, so that the block 38 on the second screw rod 37 moves upward until it contacts the bottom of the steel structure. At this time, the block 38 provides support and can control the auxiliary support frame 48 to descend so that it no longer provides support. At the same time, it will not hinder the turning of the steel structure. At this time, the primer spraying component 3 can be used to spray primer on the three sides of the steel structure except the bottom surface. When the primer is solidified and the fire-retardant paint sheet needs to be attached, the adhesive is first manually applied to the top of the steel structure, and the side of the paint sheet with the rough surface 23 is aligned with the side coated with the adhesive and then attached, and the adhesive is waited for to solidify.

[0120] The turning handle on the chuck 35 is turned again so that the steel structure is contacted by the blocks 38 on all sides, and the grip 47 is pulled to drive the insertion rod 43 to leave the insertion hole 40, and drive the pad 45 to compress the second spring 44, and control the turning handle 41 to rotate 90°, so that the corresponding chuck 35 drives the steel structure to rotate 90°. At this time, the side sprayed with primer is in a vertical state, and the turning handle on the chuck 35 is operated to make the blocks 38 on the side not sprayed with primer and the blocks 38 located above leave the steel structure. At this time, the primer can be sprayed on the side not sprayed with primer, and the above-mentioned gluing, attaching and flipping operations are repeated until paint chips are pasted on the four sides of the steel structure.

[0121] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
