Technical Field

[0001] The invention relates to the field of spraying equipment, in particular to a surface protection spraying equipment for steel materials used in construction. Background Art

[0002] Steel section is a strip of steel with a certain cross-sectional shape and size. It is one of the four major types of steel (plate, tube, section, wire). According to the cross-sectional shape, steel sections are divided into simple cross-sectional steel sections and complex cross-sectional steel sections (special-shaped steel). They are often used in the construction industry to build building structures.

[0003] With the development of industry, the steel structure manufacturing industry has gradually grown and developed. In the field of steel structure processing, it is often painted to increase the aesthetics and corrosion resistance of the steel structure and ensure the service life of the steel structure. However, due to the cross-sectional structure added to the steel section in order to enhance the structural strength and realize the function, there are corner gaps on the surface. When spraying on the surface, there will be problems such as inadequate and uneven spraying, which affects the spraying quality.

[0004] Therefore, a new type of construction steel surface protection spraying equipment is needed to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a surface protection spraying equipment for steel materials used in construction.

[0006] To achieve the above object, the present invention provides the following technical solutions: A surface protection spraying device for steel materials used in construction comprises a base frame, conveying frames are arranged at intervals at both ends of the base frame, an annular spraying ring is arranged perpendicular to the conveying direction of the conveying frames between the conveying frames, the conveying path of the conveying frames passes through the center of the spraying ring, a driving ring driven by a driving motor on one side is embedded in the spraying ring, spray heads are evenly distributed along the circumference of the spraying ring, and the spray heads are movably or fixedly connected to the spraying ring and the driving ring.

[0007] As a further solution of the present invention: the conveying frame includes a tripod, a conveying motor and a roller. The tripod is a right-angled triangle metal structure frame with an inclined surface of 30°, which is fixed to the top of the base. The inclined surface of the tripod is provided with a roller driven by the conveying motor. The tripods on both sides are symmetrically arranged, and the rollers on both sides are arranged in a V-shape as a whole.

[0008] As a further solution of the present invention: the front end of the roller is arranged to protrude from the edge of the tripod.

[0009] As a further solution of the present invention: a group of parallel shaft frames are vertically welded on the inclined surface of the tripod, and the rollers are inserted into the shaft frames and are rotatably connected to the shaft frames through bearing assemblies.

[0010] As a further solution of the present invention: the spray ring includes a ring frame and a side cover. The ring frame is a circular ring structure with a U-shaped cross-section and an open side. The open side is shielded by a detachable ring-shaped side cover. An annular drive ring is concentrically nested in the ring frame. A transmission rack is provided on the drive ring, which is connected to a drive gear transmission connected to a keyway on a drive shaft connected to an output end of a drive motor. Both the ring frame and the circumferential surface of the drive ring are provided with a transparent window for the nozzle to pass through.

[0011] As a further solution of the present invention: the ring frame and the driving ring are provided with rows of holes in a direction perpendicular to the center of the ring frame, the holes are threadedly connected with connecting bolts, and the nozzle is connected to the ring frame and the driving ring via the connecting bolts.

[0012] As a further solution of the present invention: a strip-shaped groove in the same direction as the arrangement direction of the holes is recessed at the position where the nozzle surface is connected to the connecting bolt. The connecting bolt is divided into two types: one with a contact shaft at the tail end and one without a contact shaft. The contact shaft is a shaft structure that is rotatably connected to the tail end of the connecting bolt.

[0013] As a further solution of the present invention: at least two drive rings with different diameters are arranged in the ring frame, and the drive rings are concentrically nested and rotatably connected.

[0014] As a further solution of the present invention, the diameters of the driving gears meshing with the transmission racks of different driving rings are set differently. Beneficial Effects

[0015] 1. The spray ring of the present invention is embedded with a driving ring driven by a driving motor on one side, and nozzles are evenly distributed along the circumference of the spray ring. The nozzles are movably or fixedly connected to the spray ring and the driving ring. The present invention reciprocates the driving ring in the spray ring through the driving motor. According to the different connection modes and angles between the nozzles and the spray ring and the driving ring at different positions, each nozzle sprays different structures on the surface of the steel material in different reciprocating motion postures or static states, so as to achieve the purpose of adapting to different cross-sectional structures while improving the uniformity of the spraying effect.

[0016] 2. A strip-shaped slide groove having the same direction as the arrangement of the holes is recessed at the position where the nozzle surface of the present invention is connected to the connecting bolt. The connecting bolt is divided into two types, one with a contact shaft at the tail end and one without a contact shaft. The contact shaft is a shaft structure that is rotatably connected to the tail end of the connecting bolt. By setting the two connecting bolts with a contact shaft at the tail end and without a contact shaft, the connecting bolt without a contact shaft can achieve a fixed connection and a sliding connection with the nozzle by adjusting the degree of thread locking and cooperating with the slide groove on the nozzle, while the connecting bolt with a contact shaft can achieve a rotatable connection with the nozzle. By using the three connection methods in conjunction with the different connection points of the nozzle, switching of multiple spraying modes can be achieved.

[0017] 3. In the present invention, the diameters of the driving gears meshing with the transmission racks of different driving rings are set differently. By setting driving gears of different diameters, the angular velocity errors between different driving rings are corrected to keep the relative angular movement between adjacent driving rings consistent, so as to realize the movement of the fixed nozzle on the driving ring toward the center position of the spray ring for spraying, and improve the spraying uniformity through the movement of the nozzle, or amplify the angular error of the drive between different driving rings to realize the movement and directional spraying of the nozzle movably connected on the driving ring, so as to adapt to the spraying of some corner positions on the steel surface.

[0028] The present embodiment provides a surface protection spraying equipment for steel materials for construction, comprising a base frame 1, with conveying frames 2 arranged at intervals at both ends of the base frame 1, and an annular spraying ring 3 arranged perpendicular to the conveying direction of the conveying frames 2 between the conveying frames 2, and the conveying path of the conveying frames 2 passes through the center of the spraying ring 3, and the spraying ring 3 is embedded with a driving ring 33 driven by a driving motor 4 on one side, and nozzles 35 are evenly distributed along the circumference of the spraying ring 3, and the nozzles 35 are movably or fixedly connected to the spraying ring 3 and the driving ring 33.

[0029] Among them, the conveying frame 2 includes a tripod 21, a conveying motor 23 and a roller 24. The tripod 21 is a right-angled triangle metal structure frame with an inclined surface of 30°, which is fixed to the top of the base 1. The inclined surface of the tripod 21 is provided with a roller 24 driven by the conveying motor 23. The tripods 21 on both sides are symmetrically arranged, and the rollers 24 on both sides are arranged in a V-shape as a whole. By setting the conveying frame 2 in a V-shape, the contact area between the roller 24 and the profile is reduced, thereby reducing the damage to the paint surface of the steel that is not completely adhered and cured after spraying.

[0030] Specifically, the front end of the roller 24 is arranged to protrude from the edge of the tripod 21, so that the position of the tripod 21 is relatively moved outward, thereby reducing the impact on the steel.

[0031] Furthermore, a group of parallel shaft frames 22 are vertically welded on the inclined surface of the tripod 21, and the roller 24 is inserted into the shaft frame 22 and is rotatably connected to the shaft frame 22 through a bearing assembly. The group of shaft frames 22 improves the support for the roller 24 and prevents the roller 24 from extending outward and being suspended in the air, which brings excessive radial load to the transmission motor 23.

[0032] Among them, the spray ring 3 includes a ring frame 31 and a side cover 32. The ring frame 31 is a circular ring structure with a U-shaped cross-section and an open side. The open side is shielded by a detachable ring side cover 32. An annular drive ring 33 is concentrically nested in the ring frame 31. A transmission rack 34 is provided on the drive ring 33, which is transmission-connected to a drive gear 6 connected to a keyway on a drive shaft 5 connected to the output end of a drive motor 4. The circumferential surfaces of the ring frame 31 and the drive ring 33 are provided with transparent windows for the nozzle 35 to pass through.

[0033] Specifically, the ring frame 31 and the driving ring 33 are provided with rows of holes in a direction perpendicular to the center of the ring frame 31, and the inner threads of the rows of holes are connected with connecting bolts 36, and the nozzle 35 is connected to the ring frame 31 and the driving ring 33 through the connecting bolts 36; By setting the row of holes, the nozzle 35 can achieve two trends of being fixed and moving with the drive through the connection between the ring frame 31 and the driving ring 33.

[0034] Furthermore, a strip-shaped slide groove in the same direction as the arrangement direction of the holes is concavely provided at the position where the surface of the nozzle 35 is connected to the connecting bolt 36. The connecting bolt 36 is divided into two types: one with a contact shaft 37 at the tail end and one without a contact shaft 37. The contact shaft 37 is a shaft structure that is rotatably connected to the tail end of the connecting bolt 36. By setting two types of connecting bolts 36, one with a contact rotating shaft 37 and one without a contact rotating shaft 37 at the tail end, the connecting bolt 36 without the contact rotating shaft 37 can achieve a fixed connection and a sliding connection with the nozzle 35 by adjusting the degree of thread locking and cooperating with the slide groove on the nozzle 35, while the connecting bolt 36 with the contact rotating shaft 37 can achieve a rotational connection with the nozzle 35. Through the three connection methods and the different connection points of the nozzle, switching of multiple spraying modes can be realized.

[0035] Furthermore, at least two drive rings 33 of different diameters are arranged in the ring frame 31, and the drive rings 33 are concentrically nested and rotatably connected; By setting up the nested drive rings 33 and utilizing the difference in angular velocity of movement of different drive rings 33, the difference in rate change when the nozzle 35 is connected to different drive rings 33 can be realized, so that the angle change rate of the nozzle 35 can be adjusted by connecting different points. The angle change during spraying movement can also be reduced by movably connecting the nozzle 35 to the two drive rings 33, thereby achieving more spraying changes.

[0036] Furthermore, the diameters of the drive gears 6 meshed with the transmission racks 34 of different drive rings 33 are set differently; By setting driving gears 6 of different diameters, the angular velocity errors between different driving rings 33 are corrected to keep the relative angular movement between adjacent driving rings 33 consistent, so as to realize the movement of the fixed nozzle 35 on the driving ring 33 toward the center position of the spray ring for spraying, and improve the spraying uniformity through the movement of the nozzle 35, or amplify the angular error of the driving between different driving rings 33 to realize the movement and directional spraying of the nozzle 35 movably connected to the driving ring 33, so as to adapt to the spraying of some corner positions on the steel surface.

[0037] When implementing the technical solution described in this embodiment, the steel material after surface rust removal and cleaning passes through the center of the spray ring 3 through the conveyor rack 2 on one side, and the surface of the steel material is sprayed by the nozzle 35 pre-installed on the spray ring 3. At the same time, the driving motor 4 on one side of the spray ring 3 reciprocates the driving ring 33 in the spray ring 3. According to the different connection methods and angles between the nozzle 35 and the spray ring 3 and the driving ring 33 at different positions, each nozzle 35 sprays different structures on the surface of the steel material in different reciprocating motion postures or static states to achieve a uniform spraying effect. Finally, the steel material is exported through the conveyor rack 2 on the other side to enter the subsequent process.
