Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, specifically a fireproof coating spraying device for building steel components. Background Technology

[0002] Steel structural components are a type of load-bearing structural component widely used in the modern construction industry. They are typically made of steel and are characterized by high strength and quick construction, commonly used in bridges, factories, large stadiums, and high-rise buildings. However, due to the poor fire resistance of steel, it is prone to a sharp drop in strength and loss of load-bearing capacity under high temperatures. Therefore, fire-retardant coatings are needed to improve its fire resistance. Existing fire-retardant coating spraying equipment for steel components is complex in practice due to the presence of two opposing grooves on steel components such as I-beams. It often requires flipping the steel component and spraying both sides in batches. This method is not only inefficient but also prone to uneven coating thickness due to variations in spraying distance, thus affecting the fire resistance and overall quality of the steel components. Therefore, improving spraying efficiency, simplifying the operation process, and ensuring coating uniformity have become urgent problems to be solved in the industry.

[0003] Utility model patent CN221063220U discloses a fire-retardant coating spraying device for steel components. The device includes a main body with a center marker line at its upper end. A steel component body is connected to the upper end of the center marker line. A slide rail is located at the upper end of the main body, and a support positioning frame is fixed thereto. A sleeve is connected to the right side of the main body, a first clamping plate is connected to the right side of the steel component body, and a second clamping plate is connected to the left side of the steel component body. This fire-retardant coating spraying device for steel components utilizes a control handle on the right side of the main body. By adjusting the rotation of the rotating shaft, the first and second clamping plates can be moved simultaneously towards or in opposite directions. This ensures that the centerline of the steel component, the center marker line, and the centerline of the branch pipe are aligned on the same vertical plane, achieving the same distance between the two spray heads and the two sides of the steel component, thus guaranteeing consistent coating thickness.

[0004] The existing technology described above uses a control handle on the right side of the spraying device. The rotation of the adjusting shaft drives the first and second clamping plates to move in opposite directions, aligning the centerline of the steel component with the center mark line. Two spray heads then spray both sides of the steel component to achieve consistent coating thickness. However, this device has several drawbacks: First, to align the centerline of the steel component with the center mark line, the operator must repeatedly rotate the control handle, causing the connecting column to rotate within the sleeve, which in turn rotates the adjusting shaft. Simultaneously, the first and second clamping plates move along the threads. This alignment operation is cumbersome and inconvenient for large-scale construction. Second, the device's structural design is complex; the sliding rails can easily lead to impurity accumulation or paint penetration, causing the alignment structure to gradually fail and hindering long-term use. To address these issues, we propose a fire-retardant coating spraying device for building steel components, simplifying the operation process and improving the long-term reliability of the spraying device. Utility Model Content

[0005] The purpose of this invention is to provide a fire-retardant coating spraying device for building steel components to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fire-retardant coating spraying device for building steel components includes a base. The top of the base is provided with a support assembly. The support assembly includes a strip-shaped horizontal plate, which serves as a horizontal mounting base for the support assembly. A T-shaped through groove is provided on the top of the strip-shaped horizontal plate, providing a sliding track for a first T-shaped slider. Two first T-shaped sliders are movably connected within the T-shaped through groove. The first T-shaped sliders are used to adjust the support position laterally to adapt to the length of the steel component. A rectangular hole is provided on the side of the first T-shaped slider. A locking bolt is threaded to the bottom of the inner wall of the rectangular hole. The bottom end of the locking bolt abuts against the bottom of the inner wall of the T-shaped through groove. The locking bolt is tightened to abut against the bottom of the T-shaped through groove to lock the position of the first T-shaped slider.

[0008] The top of each of the two first T-shaped sliders is provided with a rectangular support plate, which directly supports both ends of the steel component. The top of the rectangular support plate is provided with a U-shaped positioning groove, which restricts the lateral displacement of the steel component. The two rectangular support plates jointly support the steel component, which is an I-beam or similar profile to be coated with fire retardant paint.

[0009] The base has fixed vertical plates on both the left and right sides of the top. There are two horizontal sliding rods arranged symmetrically between the two fixed vertical plates and near the top. The horizontal sliding rods provide horizontal sliding guidance for the movable seat. The two horizontal sliding rods are slidably connected to the movable seat. The movable seat carries the sprayed part and moves along the sliding rods to cover the length of the steel component.

[0010] The top of the movable base is provided with a paint input pipe, which connects the external feeding system and the spraying component. The bottom end of the paint input pipe is connected to the spraying component, which is used to uniformly spray paint into the groove of the steel component.

[0011] The spraying component includes two U-shaped liquid guide tubes arranged symmetrically front to back. The U-shaped liquid guide tubes distribute the paint to the spraying structures on both sides. The bottom end of the paint input tube is connected to the two U-shaped liquid guide tubes through a T-junction. The output ends of the two U-shaped liquid guide tubes are connected to U-shaped plate-shaped spray pipes. The U-shaped plate-shaped spray pipes are adapted to the shape of the grooves in the steel components to fully cover the spraying surface. The two U-shaped plate-shaped spray pipes are located in the two grooves of the steel components, respectively. Multiple nozzles are evenly distributed on the outer side of the U-shaped plate-shaped spray pipes, and the nozzles realize uniform atomization spraying of the paint.

[0012] Preferably, the two rectangular support plates are arranged symmetrically from left to right, and the two ends of the bottom of the steel component are respectively located in two U-shaped positioning grooves. The U-shaped positioning grooves ensure that the steel component is placed stably and prevents it from shifting.

[0013] Preferably, the support assembly further includes a plurality of second T-shaped sliders, the number of which is adjusted according to the length of the steel component. The second T-shaped sliders are slidably connected in the T-shaped through groove. A circular support plate is provided on the top of the second T-shaped slider. The top of the circular support plate abuts against the bottom of the steel component. The circular support plate disperses the pressure on the steel component and enhances the support stability.

[0014] Preferably, each of the two fixed vertical plates has a drive component on its opposite sides for driving the moving seat to move left and right. The drive component provides automated movement control to replace manual operation. The drive component includes a housing, which encapsulates the drive component and protects the internal structure.

[0015] Preferably, a partition is provided inside the housing and near the front side to separate the motor and the winding drum to prevent interference. A motor is provided on the front side of the partition. The motor outputs power to drive the winding drum to rotate. The motor is connected to an external power supply and controller. The motors of the two driving components work synchronously. The output shaft of the motor passes through the front side of the partition and is coaxially connected to the winding drum. The winding drum winds up and down the traction rope to control the movement of the moving seat.

[0016] Preferably, a traction rope is wound on the winding drum, and a hole is opened on the side of the fixed vertical plate for the traction rope to pass through. The traction rope transmits driving force to the moving seat to achieve bidirectional movement.

[0017] Preferably, a connecting ring is provided in the middle of both the left and right sides of the movable seat, and the traction ropes of the two driving components are respectively connected to the two connecting rings. The connecting rings fix the ends of the traction ropes to achieve stable traction.

[0033] Please see Figures 1-8 This utility model provides a technical solution:

[0034] A fire-retardant coating spraying device for building steel components includes a base 100. A support component 200 is provided on the top of the base 100. The support component 200 includes a strip horizontal plate 210, which serves as a horizontal mounting base for the support component. A T-shaped through groove 211 is provided on the top of the strip horizontal plate 210. The T-shaped through groove 211 provides a sliding track for a first T-shaped slider 220. Two first T-shaped sliders 220 are movably connected in the T-shaped through groove 211. The first T-shaped sliders 220 are used to adjust the support position laterally to adapt to the length of the steel component 300. A rectangular hole 221 is provided on the side of the first T-shaped slider 220. A locking bolt 240 is threaded to the bottom of the inner wall of the rectangular hole 221. The bottom end of the locking bolt 240 abuts against the bottom of the inner wall of the T-shaped through groove 211. The locking bolt 240 locks the position of the first T-shaped slider 220 by tightening it against the bottom of the T-shaped through groove 211.

[0035] The top of each of the two first T-shaped sliders 220 is provided with a rectangular support plate 230. The rectangular support plate 230 directly supports both ends of the steel component 300. The top of the rectangular support plate 230 is provided with a U-shaped positioning groove 231. The U-shaped positioning groove 231 restricts the lateral displacement of the steel component 300. The two rectangular support plates 230 jointly support the steel component 300, which is an I-beam or similar profile to be sprayed with fireproof coating.

[0036] The base 100 has fixed vertical plates 400 on both the left and right sides of the top. There are two horizontal slide rods 500 arranged symmetrically between the two fixed vertical plates 400 and near the top. The horizontal slide rods 500 provide horizontal sliding guide for the movable seat 600. The two horizontal slide rods 500 are slidably connected to the movable seat 600. The movable seat 600 carries the sprayed part 800 and moves along the slide rods to cover the length of the steel component 300.

[0037] The top of the movable base 600 is provided with a paint input pipe 700, which connects the external feeding system and the spraying component 800. The bottom end of the paint input pipe 700 is connected to the spraying component 800, which is used to uniformly spray paint into the groove of the steel component 300.

[0038] The spraying component 800 includes two U-shaped liquid guide tubes 810 arranged symmetrically front to back. The U-shaped liquid guide tubes 810 distribute the paint to the spraying structures on both sides. The bottom end of the paint input pipe 700 is connected to the two U-shaped liquid guide tubes 810 through a T-connector. The output ends of the two U-shaped liquid guide tubes 810 are connected to U-shaped plate-shaped spray pipes 820. The U-shaped plate-shaped spray pipes 820 are adapted to the groove shape of the steel component 300 to fully cover the spraying surface. The two U-shaped plate-shaped spray pipes 820 are located in the two grooves of the steel component 300, respectively. Multiple nozzles 830 are evenly distributed on the outer side of the U-shaped plate-shaped spray pipes 820. The nozzles 830 realize uniform atomization spraying of paint.

[0039] In this embodiment, the two rectangular support plates 230 are arranged symmetrically from left to right, and the two ends of the bottom of the steel component 300 are respectively located in the two U-shaped positioning grooves 231. The U-shaped positioning grooves 231 ensure that the steel component 300 is placed stably and prevents it from shifting.

[0040] Specifically, the support assembly 200 also includes a plurality of second T-shaped sliders 250. The number of second T-shaped sliders 250 is adjusted according to the length of the steel component 300. The second T-shaped sliders 250 are slidably connected in the T-shaped through groove 211. A circular support plate 251 is provided on the top of the second T-shaped slider 250. The top of the circular support plate 251 abuts against the bottom of the steel component 300. The circular support plate 251 disperses the pressure on the steel component 300 and enhances the support stability.

[0041] Furthermore, each of the two fixed vertical plates 400 has a drive component 900 on its opposite sides for driving the movable seat 600 to move left and right. The drive component 900 provides automated movement control to replace manual operation. The drive component 900 includes a housing 910, which encapsulates the drive component and protects the internal structure.

[0042] Furthermore, a partition 911 is provided inside the housing 910 near the front side. The partition 911 separates the motor 920 from the winding drum 930 to prevent interference. The motor 920 is located on the front side of the partition 911. The motor 920 outputs power to drive the winding drum 930 to rotate. The motor 920 is connected to an external power supply and controller. The motors 920 of the two drive units 900 work synchronously. The output shaft of the motor 920 passes through the front side of the partition 911 and is coaxially connected to the winding drum 930. The winding drum 930 winds up and unwinds the traction rope 940 to control the displacement of the moving seat 600.

[0043] Furthermore, a traction rope 940 is wound on the winding drum 930, and a hole is opened on the side of the fixed vertical plate 400 for the traction rope 940 to pass through. The traction rope 940 transmits driving force to the moving seat 600 to achieve bidirectional movement.

[0044] Furthermore, a connecting ring 610 is provided in the middle of both sides of the movable seat 600. The traction ropes 940 of the two drive components 900 are respectively connected to the two connecting rings 610. The connecting rings 610 fix the ends of the traction ropes 940 to achieve stable traction.

[0045] In this embodiment, the fire-retardant coating spraying device for building steel components is used by first manually adjusting the distance between the two first T-shaped sliders 220 in the T-shaped groove 211 on the horizontal strip 210 to make the U-shaped positioning groove 231 fit the length of the steel component 300. Then, the locking bolts 240 in the rectangular holes 221 on the side of the first T-shaped slider 220 are tightened to fix the position. The two ends of the steel component 300 to be sprayed are placed in the U-shaped positioning grooves 231 on the top of the two rectangular support plates 230 of the support assembly 200, respectively. If the steel component 300 is long, the second T-shaped slider 250 can be slid along the T-shaped groove 211 and its top can be adjusted. The circular support plate 251 is moved to a suitable position to distribute the pressure on the steel component 300. Then, the drive unit 900 on the outside of the two fixed vertical plates 400 is started. The motor 920 drives the winding drum 930 to rotate and retract the traction rope 940. The traction rope 940 pulls the moving seat 600 along the transverse slide bar 500 at a uniform speed through the connecting ring 610. At the same time, the paint input pipe 700 delivers the external fireproof paint to the spraying part 800. After being distributed by the U-shaped liquid guide pipe 810, the nozzles 830, which are evenly distributed on the outside of the U-shaped plate-shaped spray pipe 820 located in the groove of the steel component 300, simultaneously spray the surface of the groove on both sides, completing the integrated spraying operation without flipping.
