Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of steel surface treatment, in particular to a steel surface treatment equipment and method. BACKGROUND

[0002] Steel is widely used and has many varieties. According to different cross-sectional shapes, steel is generally divided into four categories: profiled material, plate material, pipe material and metal products. Profiled material is further divided into heavy rail, light rail, large section steel and other varieties. In order to save warehouse resources, large section steel is usually placed outdoors. However, it will inevitably be exposed to rain for a long time, resulting in rust. Therefore, before leaving the factory, the surface of the large section steel needs to be treated to remove rust. If it is used in coastal construction or offshore operations, the steel needs to be treated to remove rust, shot blasting and spraying to slow down the rusting of the steel during use.

[0003] During the surface treatment of steel, rust removal is the first step before painting the surface of the steel. Rust is a loose, porous and continuously expanding material. If it is not removed, painting on it will cause deformation of the painted surface due to the expansion of rust, and further cause micro-cracks to accelerate the entry of water, oxygen and corrosive ions, thereby greatly affecting the corrosion protection effect of the paint film and greatly reducing the service life of the steel. Therefore, rust removal plays a crucial role in the corrosion protection of the steel surface. After rust removal, the surface of the steel is treated again using a shot blasting device to increase the roughness of the steel surface and improve the painting effect of the steel surface. After shot blasting, the steel is painted to slow down the rusting of the steel.

[0004] In the prior art, rust removal of large section steel is mostly done manually by workers. Dust particles are scattered during the rust removal process, which seriously affects the health of workers. In addition, due to the length and weight of large section steel, the steel needs to be lifted and turned over by equipment during the rust removal process to successfully remove rust from all surfaces of the steel. In the subsequent shot blasting and painting process, the steel also needs to be turned over frequently using equipment. Since workers frequently use equipment to turn over the steel, not only does it increase the labor intensity of workers, but it also affects the surface treatment efficiency of large section steel.

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings shown in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0040] Embodiment one:

[0041] A steel surface treatment equipment, steel is widely used, a variety of, according to the different section shape, steel is generally divided into four categories, such as profiled bar, plate, pipe and metal products, profiled bar is divided into heavy rail, light rail, large section steel and other varieties; and the length of large section steel after production is 4-10 meters, in order to save warehouse resources, usually all open-air placement, and open-air placement will inevitably contact with rain for a long time, resulting in rust, so the surface of large section steel needs to be derusted before leaving the factory, if it is used in coastal construction or offshore operation, the steel also needs to be derusted, shot blasting and sprayed for surface treatment, so as to slow down the rusting of steel during use;

[0042] In the process of surface treatment of steel, rust removal is the first step before the steel surface is sprayed, because rust is a loose, porous and expanding material. If it is not removed, painting on it will cause deformation of the coating surface due to the expansion of rust, and further produce small cracks to accelerate the entry of water, oxygen and corrosion ions, thereby greatly affecting the corrosion protection effect of the paint film and greatly reducing the service life of steel. Therefore, rust removal plays a crucial role in the corrosion protection of steel surface. After rust removal, the surface of the steel is treated again by a shot blasting device to increase the roughness of the steel surface and improve the spraying effect of the steel surface. After shot blasting, spraying treatment is carried out to slow down the rusting of the steel.

[0043] In the prior art, the rust removal of large steel is mostly carried out manually by workers. Dust particles are scattered during the rust removal process, which seriously affects the health of workers. Moreover, due to the length and weight of large steel, the workers need to use equipment to lift and turn over the steel during the rust removal process to successfully remove rust from each surface of the steel. In the subsequent shot blasting and spraying process, the steel also needs to be turned over frequently using equipment. Since the workers frequently use equipment to turn over the steel, not only does it increase the labor intensity of the workers, but also it affects the surface treatment efficiency of the large steel.

[0044] In order to effectively solve the above problems, as shown in the drawings Figures 1-9 , it comprises a transmission platform, a rust removal device and a shot blasting device. The transmission platform is arranged on both sides of the rust removal device, and the shot blasting device is arranged on one side of the transmission platform. The transmission platform is a conventional device for conveying steel in the art, such as a conveyor belt. The shot blasting device is of an open type. The rust removal device comprises a body 1, which comprises a driving unit and a control unit. The driving unit drives the body 1 to work, and the control unit controls the driving unit to work according to parameters. The rust removal device further comprises:

[0045] A first pipe 12 is rotatably connected to the top of the body 1.

[0046] A first telescopic rod 13 is arranged on the inner wall of the first pipe 12, and the output end of the first telescopic rod 13 faces the axis direction of the first pipe 12. The first telescopic rod 13 is powered by direct current, and the control unit in the body 1 controls the work of the first telescopic rod 13.

[0047] The output end of the first telescopic rod 13 is provided with a fixed block 2, and a first slot 21 is formed in the fixed block 2; a second slot 22 is formed in the inner wall of the side of the first slot 21 close to the axis of the first pipe 12, and a sliding block 23 is slidably connected in the first slot 21, and the top of the sliding block 23 penetrates through the second slot 22 and is close to the axis of the first pipe 12; the top of the sliding block 23 is provided with a cleaning brush 24; the number of the first telescopic rod 13 and the fixed block 2 is four;

[0048] The fixed block 2 is fixedly connected with a placing box 3, and the placing box 3 is provided with a driving piece 31; the output end of the driving piece 31 is provided with a connecting rod 32, and one end of the connecting rod 32 is connected with one side of the sliding block 23; the driving piece 31 is an electric telescopic rod, and the driving piece 31 drives the sliding block 23 to reciprocate in the first slot 21 through the connecting rod 32;

[0049] The bristles in the cleaning brush 24 are made of wear-resistant metal material, and the bristles in the cleaning brush 24 are arc-shaped; the bristles in the cleaning brush 24 are made of high-manganese wear-resistant steel material, the bristles in the cleaning brush 24 are two end portions in the same plane, and the middle portion of the bristles in the cleaning brush 24 is curved into an arc shape;

[0050] Specific working process: when the surface of a large section steel is treated, for example, H type steel, first, the steel is hung on the transmission platform, and then the steel surface treatment equipment is started, the transmission platform transmits the steel to the direction of the first pipe 12, one end of the steel penetrates through the first pipe 12, and the steel is located in the gap between the four fixed blocks 2, the four fixed blocks 2 support and clamp the steel, then the body 1 of the rust removal device controls the driving piece 31 in the placing box 3 to work, the output end of the driving piece 31 drives the sliding block 23 to reciprocate in the first slot 21 and the second slot 22 through the connecting rod 32, and the top of the sliding block 23 drives the cleaning brush 24 on the top of the fixed block 2 to reciprocate, in the process that the steel continuously penetrates through the gap between the four fixed blocks 2, the cleaning brush 24 continuously reciprocates to continuously brush the surface of the steel, the rust on the surface of the steel is removed, and the efficiency of rust removal on the surface of the steel is improved;

[0051] Further, in the rust removal work of H-shaped steel, channel steel and I-beam with grooves 43, the existing technology usually uses manual rust removal equipment to remove rust from such steel, because such steel has grooves 43, ordinary rust removal equipment cannot easily enter the grooves 43 of such steel for polishing, and even if it enters the grooves 43 for polishing and rust removal, it still needs to be lifted by additional lifting equipment to turn over, so that the rusted surface of the steel placed on the ground before polishing can be in contact with the ground, reducing the rust removal efficiency of the steel; Therefore, by setting the number of the first telescopic rod 13 and the fixed block 2 to four, when the H-shaped steel, channel steel and I-beam are transmitted to the transmission platform between the four fixed blocks 2, two of the four fixed blocks 2 enter the grooves 43 of such steel, and the reciprocating motion of the cleaning brush 24 removes rust from the inside of the grooves 43 of such steel; The other two of the four fixed blocks 2 remove rust from the flat surfaces on both sides of the H-shaped steel, channel steel and I-beam, so that the rust removal device can simultaneously process all surfaces of the H-shaped steel, channel steel and I-beam, thereby reducing the work intensity of the workers in rust removal processing, improving the rust removal efficiency of the rust removal device for such steel, and thus improving the surface treatment efficiency of the steel;

[0052] The arrangement order of the transmission platform, the rust removal device and the shot blasting device is in turn, the transmission platform, the rust removal device, the shot blasting device, the transmission platform; After the rust removal treatment of the steel is completed, the transmission device between the rust removal device and the shot blasting device continues to transmit the steel with completed rust removal to the shot blasting device, and in the process of shot blasting the steel, the worker can control the machine body 1 to drive the first pipe 12 to rotate, the first pipe 12 drives the first telescopic rod 13 and the fixed block 2 to rotate, and the fixed block 2 clamps and supports the steel while rotating around the axis of the first pipe 12, so that the steel is continuously turned over during the shot blasting process, and the steel is moved into the shot blasting device while being turned over, so that the shot blasting device can more effectively perform shot blasting treatment on all surfaces of the steel, avoiding the need for the worker to turn over the steel for the next shot blasting treatment after each shot blasting treatment of a surface of the steel, improving the shot blasting treatment efficiency of the shot blasting device for such steel, and thus improving the surface treatment efficiency of the steel;

[0053] After the shot blasting treatment of the steel, the worker collects the steel and transports it to the spraying workshop, and then the worker sprays the protective coating on the surface of the steel in the spraying workshop, thereby completing the surface treatment work of the steel;

[0054] The brush in the cleaning brush 24 is made of high manganese steel material, which has two main characteristics: first, the greater the external impact, the higher the surface wear resistance of the brush; second, as the surface hardening layer is gradually worn out, a new work hardening layer will be continuously formed; the brush has excellent wear resistance to strong impact wear and high stress wear, so that the cleaning brush 24 will not be broken during the reciprocating brushing process on the steel surface, and the mechanical processing performance is good.

[0055] The brush in the cleaning brush 24 is made of high manganese steel material, which has two main characteristics: first, the greater the external impact, the higher the surface wear resistance of the brush; second, as the surface hardening layer is gradually worn out, a new work hardening layer will be continuously formed; the brush has excellent wear resistance to strong impact wear and high stress wear, so that the cleaning brush 24 will not be broken during the reciprocating brushing process on the steel surface, and the mechanical processing performance is good;

[0056] Embodiment two:

[0057] On the basis of embodiment one, the fixed block 2 is provided with a first plate 4 away from the two sides of the second groove 22, and the two sides of the fixed block 2 close to the first plate 4 are provided with third grooves 25, and the sliding block 23 is fixedly connected with a sleeve rod 41 corresponding to the position of the third groove 25, and the sleeve rod 41 is externally sleeved with a sleeve 42; the sleeve rod 41 and the sleeve 42 are provided with springs, and the end of the sleeve 42 away from the sliding block 23 is fixedly connected with the first plate 4;

[0058] The first plate 4 is provided with a groove 43 away from the fixed block 2, the sliding block 23 is fixedly connected with a first belt 5 on the top, and the two ends of the first belt 5 are penetrated through the groove 43, and the cleaning brush 24 is arranged on the side of the first belt 5 away from the sliding block 23;

[0059] The side of the first plate 4 away from the placing box 3 is fixedly connected with a guide plate 6;

[0060] One end of the guide plate 6 is close to the fixed block 2, and the other end is located on one side of the first plate 4, and the surface of the guide plate 6 is smooth treated;

[0061] Specific workflow: when the steel is located in the gap between the four fixed blocks 2 at one end, for example H-shaped steel, when processing H-shaped steel of different width sizes, the groove 43 in the H-shaped steel extrudes the two side inner walls of the first plate 4, the first plate 4 is extruded by the extrusion force and drives the sleeve 42 to move into the third groove 25, so that the sleeve rod 41 gradually extends into the sleeve 42 to extrude the spring between the sleeve 42 and the sleeve rod 41, the spring between the sleeve 42 and the sleeve rod 41 is extruded to generate a counterforce to push the sleeve 42 away from the third groove 25, the sleeve 42 drives the first plate 4 away from the fixed block 2, and the two first plates 4 on both sides of the fixed block 2 are away from each other and extrude the inner wall of the groove 43 in the H-shaped steel; when the sliding block 23 reciprocates, the sliding block 23 drives the sleeve rod 41 to reciprocate, the sleeve rod 41 drives the first plate 4 to reciprocate through the sleeve 42, forming the reciprocating movement of the sliding block 23 and the first plate 4, the first belt 5, and the cleaning brush 24 on the first belt 5, the cleaning brush 24 reciprocates the inner wall of the groove 43 in the H-shaped steel, and the cooperation of the first plate 4, the first belt 5 and the cleaning brush 24 increases the surface area of the steel surface brushed by the cleaning brush 24, thereby improving the rust removal effect;

[0062] Through the cooperation of the first plate 4, the sleeve 42 and the sleeve rod 41, when the width of the groove 43 in the H-shaped steel is small, the sleeve 42 and the sleeve rod 41 are contracted, which adapts to the small width of the groove 43 in the H-shaped steel and brushes, when the width of the groove 43 in the H-shaped steel is large, the sleeve 42 and the sleeve rod 41 are stretched, which adapts to the large width of the groove 43 in the H-shaped steel and brushes, thereby increasing the adaptability of the rust removal device to the width size change of the H-shaped steel and improving the use convenience of the equipment;

[0063] Further, through the reciprocating movement of the sliding block 23 and the first plate 4, the first belt 5 can be well supported to make the cleaning brush 24 closely contact with the inner wall of the groove 43 in the H-shaped steel and better realize the reciprocating brushing and rust removal, thereby improving the rust removal effect of the cleaning brush 24 on the inner wall of the groove 43 in the H-shaped steel and improving the rust removal effect on the steel;

[0064] When the steel is inserted into the gap between the four fixed blocks 2 at one end, by arranging the guide plates 6, the inner wall of the groove 43 in the H-shaped steel first contacts the guide plates 6, as the H-shaped steel continuously inserts into the gap between the four fixed blocks 2, the inner wall of the groove 43 in the H-shaped steel extrudes and is guided by the guide plates 6, so that the two guide plates 6 are close to each other, and the guide plates 6 drive the first plate 4 to be close to each other, until the first plate 4 is located in the groove 43 of the H-shaped steel for rust removal work, so that the first plate 4 can automatically adapt to the width of the groove 43 in the H-shaped steel without worker intervention, thereby increasing the self-adaptability of the equipment and improving the use convenience of the equipment during replacement of H-shaped steel of different widths;

[0065] Meanwhile, the smooth surface of the guide plate 6 reduces the friction between the inner wall of the H-shaped steel and the guide plate 6 when the steel extends into the gap between the four fixing blocks 2, improves the smoothness of the movement of the H-shaped steel, and is more conducive to the smooth progress of the rust removal work of the steel.

[0066] Example Three

[0067] On the basis of Example Two, the first belt 5 is composed of a plurality of first bars 51, and the first bar 51 is an I-shaped bar; each adjacent first bar 51 is hingedly connected at a side close to the bottom position, the bottom of the first bar 51 is located in the groove 43, and the cleaning brush 24 is arranged at the top of the first bar 51; the cleaning brush 24 is arranged at the side of the first bar 51 away from the fixing block 2; the bristles in the cleaning brush 24 are arranged at the side of the first bar 51 away from the fixing block 2;

[0068] The top of the fixing block 2 is fixedly connected with a support block 7 corresponding to the positions of the edges of the two sides of the first belt 5, and the top of the support block 7 is uniformly embedded with a plurality of rolling balls 71;

[0069] Specific working process: since the first belt 5 is connected by a plurality of first bars 51, when the two first plates 4 move away from each other, the sliding block 23 pulls and fixes the middle part of the first belt 5, the distance between the two first plates 4 increases, the distance between each first plate 4 and the top of the sliding block 23 increases, the bottom of the first bar 51 continuously slides in the groove 43, and the first bar 51 passes through the groove 43 to the other side of the first plate 4, the two ends of the first belt 5 gradually approach the first plate 4, so that the first belt 5 between the two first plates 4 is also elongated when the first plates 4 move away from each other, and the brushing area of the cleaning brush 24 also increases, which can better adapt to and closely contact the inner wall of the groove 43 of the H-shaped steel with large width size, and improve the rust removal effect of the cleaning brush 24; when the two first plates 4 move close to each other, the first belt 5 between the two first plates 4 is shortened, and the brushing area of the cleaning brush 24 is also reduced, which can adapt to and closely contact the inner wall of the groove 43 of the H-shaped steel with small width size, and improve the rust removal effect of the cleaning brush 24;

[0070] When the sliding block 23 and the first plate 4 simultaneously drive the first belt 5 to reciprocate, the sliding block 23 drives the cleaning brush 24 to move through the first bar 51, the first plate 4 drives the first bar 51 to move through the groove 43, and the first bar 51 drives the cleaning brush 24 to move, so that the first belt 5 can closely contact the inner wall of the groove 43 of the H-shaped steel with the cleaning brush 24 when driving the cleaning brush 24 to remove rust from the surface of the steel, and better achieve reciprocating brushing and rust removal, improve the rust removal effect of the cleaning brush 24 on the inner wall of the groove 43 of the H-shaped steel, and thus improve the rust removal effect of the equipment on the steel;

[0071] When the steel material moves in the gap between the four fixed blocks 2, the fixed blocks 2 drive the steel material to rotate, at this time, the cleaning brush 24 not only bears the weight of the steel material, but also brushes the steel material, if the steel material is pressed on the cleaning brush 24 for a long time, the cleaning brush 24 is easy to be extruded by the steel material, resulting in excessive deformation, and losing the effect of rust removal by brushing; therefore, by arranging the supporting block 7 and the ball 71, when the steel material extends into the gap between the four fixed blocks 2, the supporting block 7 first contacts and extrudes the cleaning brush 24, and after the cleaning brush 24 is slightly bent, the ball 71 is contacted, the supporting block 7 supports the ball 71, so that the steel material can move through the ball 71 while being clamped and supported by the ball 71, thereby avoiding the excessive extrusion of the cleaning brush 24 by the weight of the steel material, improving the rust removal effect of the cleaning brush 24, and prolonging the service life of the cleaning brush 24 through the support of the supporting block 7 and the ball 71.

[0072] Embodiment four:

[0073] On the basis of embodiment three, the body 1 is provided with a dust collector 11 corresponding to one side of the first slot 21, and the air inlet of the dust collector 11 corresponds to the fixed block 2; the control unit in the body 1 controls the dust collector 11 to work with a set parameter;

[0074] The opening portions on both sides of the first pipe 12 are rotationally connected with the cover plate 14, and the cover plate 14 is a center opening; the dust collector 11 is communicated with the inside of the first pipe 12 through the air pipe passing through the cover plate 14; when the first pipe 12 rotates, the cover plate 14 is stationary;

[0075] Specific working process: while the cleaning brush 24 reciprocally brushes, the powder generated after rust removal is easy to scatter around, if not controlled and cleaned, it is easy to pollute the environment, even to be inhaled into the body of workers and harm their health, by arranging the dust collector 11, while the cleaning brush 24 removes rust from the steel material, the body 1 controls the dust collector 11 to work, the dust collector 11 inhales the dust scattered in the first pipe 12 and filters it, and then discharges the air, so as to prevent the scattered dust from polluting the environment;

[0076] By rotationally connecting the cover plate 14 with the opening portions on both sides of the first pipe 12, when the cleaning brush 24 removes rust, the cover plate 14 blocks the dust, slows down the trend of dust scattering, and through the suction of the dust collector 11, the air continuously enters the center hole of the cover plate 14 and the gap between the edge of the cover plate 14 and the inner wall of the first pipe 12, and is guided by the air pipe to be inhaled by the dust collector 11, so that the dust in the scattered air is inhaled by the dust collector 11 together with the air, further preventing the scattered dust from polluting the environment, and improving the cleanliness of the working environment;

[0077] Further, when the worker covers the plate 14, a polytetrafluoroethylene sealing ring can be installed in the gap between the edge of the cover plate 14 and the inner wall of the first pipe 12 connected in rotation, which has excellent chemical stability, sealing, high lubrication and non-stickness. By installing it in the gap between the edge of the cover plate 14 and the inner wall of the first pipe 12 connected in rotation, the first pipe 12 can be further sealed to prevent the scattered dust from causing environmental pollution and improve the cleanliness of the working environment. In addition, the lubrication between the cover plate 14 and the first pipe 12 is increased by the intervention of polytetrafluoroethylene, which avoids the rotation of the first pipe 12 driving the cover plate 14 to rotate, causing the cover plate 14 to pull the dust collector 11 through the air pipe and be damaged.

[0078] Example Five

[0079] A steel surface treatment method, as shown in the accompanying drawings Figure 10 of the specification, which is applicable to the above-mentioned treatment device, and the specific steps of the treatment method are as follows:

[0080] S1: First, the steel is hung on the transmission platform, and the transmission platform transmits the steel to the first pipe 12. One end of the steel penetrates the first pipe 12, and the four fixing blocks 2 clamp and support the steel. Then the output end of the driving part 31 drives the sliding block 23 to move through the connecting rod 32, and the sliding block 23 drives the cleaning brush 24 to move, which reciprocally brushes the surface of the steel for rust removal treatment.

[0081] S2: After the steel rust removal treatment is completed, the transmission device transmits the steel with completed rust removal treatment to the shot blasting device, and the shot blasting device further sprays the steel. The worker drives the first pipe 12 to rotate by controlling the machine body 1, and the first pipe 12 rotates through the fixing block 2. The fixing block 2 flips the steel while moving it into the shot blasting device, and the shot blasting device sprays and treats the surfaces of the steel.

[0082] S3: After the steel shot blasting treatment, the worker collects the steel and transports it to the spraying workshop. Then the worker sprays the protective coating on the surface of the steel in the spraying workshop, thereby completing the surface treatment of the steel.
