DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments of the present application.

[0017] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0018] In the description of the present application, it is necessary to point out that, unless otherwise explicitly specified and limited, the terms "mount", "connect", "connection" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium, or internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. The embodiments are written in a progressive manner.

[0019] As shown in Figures 1 to 8 The present application is a kind of steel beam production surface treatment equipment, including plate body 2 and input pipe 3 mounted on the plate body 2, the middle part of the plate body 2 is provided with a die opening consistent with the shape of the steel beam 1, and the plate body 2 is sleeved on the steel beam 1 through the die opening, the plate body 2 is provided with a sand cavity 23 inside, the sand cavity 23 is communicated with the input pipe 3, the inner wall of the die opening is provided with a nozzle communicated with the sand cavity 23, and the shape of the nozzle is consistent with the shape of the steel beam 1.

[0020] In the present application, the input pipe 3 is mainly used for conveying high-speed airflow and molding sand for surface treatment of the steel beam 1, the high-speed airflow can provide moving power for the molding sand, when the molding sand hits the surface of the steel beam 1, the impurities on the surface of the steel beam 1 can be destroyed and fall off, thereby realizing the surface treatment of the steel beam 1; the steel beam 1 can pass through the plate body 2 vertically through the die opening, the die opening can make the vertical distance between any position on the steel beam 1 in the die opening and the inner wall of the die opening equal, so that the moving path of the molding sand after leaving the plate body 2 to hitting the surface of the steel beam 1 is the same, so that the impact force on any position of the steel beam 1 is close; the nozzle on the plate body 2 is a long slit extending along the track of the die opening, so that the molding sand in the sand cavity 23 can be sprayed to the steel beam 1 through the nozzle at any position, thereby being able to clean and process all positions on the outer surface of the steel beam 1.

[0021] By making the shape of the nozzle on the plate body 2 consistent with the shape of the steel beam 1, the molding sand sprayed by the nozzle can be directed to any position on the surface of the steel beam 1, thereby realizing comprehensive treatment of the impurities on the surface of the steel beam 1, which is more simple and convenient, especially for the hidden position of the inner corner of the steel beam 1, which can also realize effective cleaning and impurity removal work; since the shape of the nozzle is consistent with the shape of the steel beam 1, it is convenient to make the vertical distance between any position on the nozzle and the steel beam 1 equal, so that the moving path of the molding sand is equal, and it is convenient to make the impact force of the molding sand on any position of the steel beam 1 close; by adopting the sand blasting cleaning method, the steel beam 1 can always be in a moving state, thereby realizing the purpose of continuous production.

[0022] Further, the plate body 2 is composed of two splicing bodies one 4 on the upper and lower sides and two splicing bodies two 5 on the left and right sides, and the splicing bodies two 5 are slidably arranged on the splicing bodies one 4, and the splicing bodies one 4 and the splicing bodies two 5 are hollow.

[0023] As shown in Figure 1 and Figure 5 The splicing bodies one 4 are in the shape of an arc, which mainly corresponds to the upper and lower side regions of the steel beam 1, and the splicing bodies two 5 are located between the two splicing bodies one 4, which mainly correspond to one of the grooves on the left and right sides of the steel beam 1, and the penetration depth of the splicing bodies two 5 in the groove on the steel beam 1 can be adjusted by adjusting the position of the splicing bodies two 5 on the splicing bodies one 4. Figure 5 As a reference, the splicing bodies two 5 are cut in the direction of the plane in which the splicing bodies two 5 are located, and the right end surface of the splicing bodies two 5 is cut, so that the splicing bodies two 5 are hollow, and the upper and lower end surfaces of the splicing bodies two 5 and the end surface of the splicing bodies two 5 facing the steel beam 1 have openings; the splicing bodies one 4 are hollow, and the inner side wall of the arc-shaped splicing bodies one 4 also has openings consistent with the shape of the splicing bodies one 4; when the splicing bodies one 4 and the splicing bodies two 5 are connected, the end of the splicing bodies one 4 is connected to one of the upper and lower surfaces of the splicing bodies two 5, and the openings on the splicing bodies one 4 are connected to the openings on one of the upper and lower surfaces of the splicing bodies two 5, and the interiors of the splicing bodies one 4 and the splicing bodies two 5 are connected through the openings; in the direction facing the steel beam 1, the part of the splicing bodies two 5 protruding from the splicing bodies one 4 will extend into the groove of the steel beam 1, so that the upper and lower sides of the protruding part of the splicing bodies two 5 correspond to the upper and lower surfaces of the groove, and the end of the protruding part of the splicing bodies two 5 corresponds to the vertical inner side wall of the groove.

[0024] In use, the input pipe 3 quickly feeds the sand and air into the interiors of the splicing bodies one 4 and the splicing bodies two 5, and the sand is sprayed onto the steel beam 1 through the openings on the splicing bodies one 4 and the openings exposed on the splicing bodies two 5, thereby cleaning the impurities on the surface of the steel beam 1.

[0025] Further, the upper and lower surfaces of the splicing bodies two 5 are provided with shielding surfaces two 7, and the end surfaces of the splicing bodies one 4 are provided with shielding surfaces one 6 for use in cooperation with the shielding surfaces two 7.

[0026] Since splice body 2 5 can move between splice bodies 1 4, when splice body 2 5 moves towards steel beam 1, the partial shielding surface 2 7 on the upper and lower surfaces of splice body 2 5 will shield part of the opening at the end of splice body 1 4, and the sand cavity 23 can remain closed. This prevents the movement distance of the end of splice body 2 5 away from steel beam 1 from being too large or the length of shielding surface 2 7 from being too small, which would result in part of the opening at the end of splice body 1 4 being exposed outside splice body 2 5 at a position away from steel beam 1, causing molding sand leakage. When splice body 2 5 moves towards a direction away from steel beam 1, shielding surface 1 6 will shield part of the opening on one of the upper and lower sides of splice body 2 5, which can also prevent molding sand leakage.

[0027] Furthermore, an inclined surface 8 is provided in the area near the end of the first splice body 4 inside the splice body 4, and the same inclined surface 8 is provided on the upper and lower sides of the inner wall of the second splice body 5.

[0028] When splice body 25 moves towards steel beam 1 between splice bodies 1 and 4, the partially obstructing surface 27 at the top of splice body 25 will occupy part of the opening at the end of the upper splice body 1. At this time, the molding sand in sand cavity 23 can be deposited on the partially obstructing surface 27 corresponding to the opening at the end of the upper splice body 1. When splice body 25 moves away from steel beam 1, part of the inclined surface 8 at the end of the lower splice body 1 will correspond to part of the opening at the bottom of splice body 25, and molding sand can be deposited on this inclined surface 8. To avoid the above phenomenon, such as Figure 4 As shown, the upper side of the splice body 2 5 and the inner area of ​​the end of the upper splice body 1 4 are both set as inclined surfaces 8. The lower side of the splice body 2 5 and the end area of ​​the lower splice body 1 4 are also set as inclined surfaces 8. This can prevent molding sand from depositing between the splice body 2 5 and the splice body 1 4. The inclined surfaces 8 at the end of the lower splice body 1 4 and the inclined surfaces 8 at the end of the upper splice body 1 4 are parallel to each other. The two inclined surfaces 8 on the upper and lower sides inside the splice body 2 5 are relatively inclined.

[0029] Furthermore, the nozzle shape on the plate 2 is a gradually deformed narrow opening 9 perpendicular to the direction of the steel beam 1.

[0030] To accelerate the ejection velocity of molding sand through the nozzle, the cross-sectional shape of the nozzle can be designed to gradually narrow towards steel beam 1, i.e., as shown below. Figure 6 The shape shown allows for faster flow of molding sand and airflow when the molding sand flows through the narrow opening 9; the openings on the upper and lower sides of the splice body 2 5 and the opening at the end of the splice body 2 5 facing the steel beam 1 are all designed as narrow openings 9.

[0031] Further, the processing device further comprises an outer box 10 located outside the plate body 2, the splicing body one 4 is fixed opposite to the outer box 10, and the bottom of the outer box 10 is provided with a negative pressure pipe 11; opposite end faces of the outer box 10 are both provided with a through opening for the steel beam 1 to pass through, and the through opening is provided with a curtain 22.

[0032] The outer box 10 can support each structure on the plate body 2 and provide a closed working environment for the plate body 2, so that the sand is not randomly scattered and is not wasted in large quantities, and the sand sprayed from the plate body 2 can fall to the bottom of the outer box 10. In order to facilitate the gathering of the sand, the bottom of the outer box 10 can be provided in an inclined state, and the negative pressure pipe 11 is installed at the lowest point of the bottom of the outer box 10. In this way, the sand can automatically roll to the position of the negative pressure pipe 11 and be sucked away by the negative pressure pipe 11. The negative pressure pipe 11 can extract the air in the outer box 10, so that the inside of the outer box 10 is in a normal pressure or negative pressure state. When the inside of the outer box 10 is in a positive pressure state, the sand is prevented from being discharged through the through opening of the outer box 10.

[0033] Further, each of the splicing bodies two 5 is provided with a movable plate 12, the movable plate 12 slides through the outer box 10 along the moving direction of the splicing body two 5, the movable plate 12 is provided with an insertion hole, a plurality of slots 13 are formed in the inner wall of the insertion hole, a rotating column 14 is slidably inserted into the insertion hole, the rotating column 14 is connected with the outer box 10 through a torsional spring 15, a plurality of horizontal plates 16 are arranged on the outer wall of the rotating column 14, the horizontal plates 16 are parallel to the axis direction of the rotating column 14, the horizontal plates 16 pass through the corresponding slots 13, a plurality of grooves 17 are arranged on the outer wall of the horizontal plates 16, and clamping edges are arranged on the inner wall of the slots 13 and used in cooperation with the grooves 17.

[0034] The torsional spring 15 provides a rotating force for the rotating column 14, so that one side wall of the horizontal plate 16 abuts against the inner wall of the slot 13. At this time, the clamping edges on the inner wall of the slot 13 are clamped into the corresponding grooves 17 on the horizontal plate 16, so that the rotating column 14 and the movable plate 12 are locked. When the position of the splicing body two 5 needs to be adjusted, the rotating column 14 is rotated, so that the grooves 17 on the horizontal plate 16 are separated from the clamping edges in the slot 13, and then the movable plate 12 can be moved.

[0035] Further, the outer box 10 is provided with a gas injection structure, the gas injection structure comprises a spray hopper one 18 located above the steel beam 1 and two spray hoppers two 19 located on both sides of the steel beam 1 in the horizontal width direction. The inside of the spray hopper one 18 is provided with a plurality of air deflectors one 20, and the plurality of air deflectors one 20 guide the airflow downwardly sprayed from the spray hopper one 18 and diffused to both sides of the width direction of the steel beam 1. The air flow in the part close to the steel beam 1 in the air flow sprayed downward by the spray pot two 19 is guided to the inner corner position of the steel beam 1 by the air guide plates two 21, and the remaining part of the air flow is guided to flow in the direction away from the steel beam 1.

[0036] In the conveying direction of the steel beam 1, the spray pot one 18 and the spray pot two 19 are located between the plate body 2 and the negative pressure pipe 11, and the spray pot one 18 and the spray pot two 19 are staggered with each other. The external air is sent into the spray pot one 18 and the spray pot two 19 by the pumping mode. The air guide plates one 20 in the spray pot one 18 are arranged in two groups in the width direction of the steel beam 1 and oppositely arranged, so that the air in the middle part of the opening of the spray pot one 18 is blown vertically downward to the upper surface of the steel beam 1, and the air on both sides of the opening of the spray pot one 18 is blown in the two opposite directions, so as to blow the sand in the upper surface of the steel beam 1. The sand in the groove on both sides of the steel beam 1 can be treated by the air discharged from the spray pot two 19. The air guide plates two 21 in the spray pot two 19 can guide a part of the air to the corner position of the groove, and the remaining part of the air is blown in the direction outside the groove, so as to blow the sand deposited in the groove, and the sand is conveniently recycled.

[0037] The above only describes the preferred embodiments of the present application. It should be noted that the ordinary skilled in the art can make some improvements and modifications without departing from the technical principles of the present application, and these improvements and modifications should also be considered as the protection scope of the present application.
