[0002] Large steel structures occupy an important position in the field of construction, including large I-beams, which are widely used in various fields such as construction, bridges and machinery manufacturing. However, it should be noted that in order to ensure the quality of I-beams, the surface of I-beams needs to be laser derusted after long-term placement. This technical means is to irradiate the metal surface with a high-energy laser beam, and the rust layer instantly absorbs energy and expands and vaporizes rapidly, and then peels off from the metal matrix; During long-term storage, since the concave part of the I-beam cannot be well exposed to sunlight, the water vapor in it is more difficult to evaporate than the water vapor on the top of the I-beam, resulting in more rust in the concave part. The rust causes its smoothness to decrease and the adhered dust to increase at the same time. In the existing technical solutions, most laser rust removal robots are not equipped with more effective dust removal equipment, which will lead to reduced efficiency and effect of laser rust removal. For this reason, we provide a large-scale steel structure surface laser rust removal robot. Summary of the invention

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] like Figures 1 to 9 As shown, the present invention provides a large-scale steel structure surface laser rust removal robot, comprising an I-beam 1, a bracket 2 and four wheels 3 staggeredly installed on the top and bottom of the bracket 2; The two wheels 3 at the upper end roll on the top of the I-beam 1, and the two wheels 3 at the lower end roll on the ground; An exhaust assembly 4 installed on the side of the bracket 2 and located in the groove of the I-beam 1; Two guide components 5 are symmetrically arranged at the top and bottom of the exhaust component 4; A laser rust removal component 8 installed on the side of the exhaust component 4; The exhaust assembly 4 is provided with a rust removal assembly 6 and a scratch removal assembly 7; The rust removal assembly 6 includes a rust removal plate 61 slidably mounted on the side of the bracket 2, the edge of the rust removal plate 61 is coated with a rubber layer, an exhaust plate 62 is arranged on the rust removal plate 61, a baffle plate 63 is respectively installed on both sides of the exhaust plate 62 through a plurality of nuts, a filter plate 3 64 is equidistantly installed on one side of the baffle plate 63 facing the inside of the exhaust plate 62, and the inside of the exhaust plate 62 is connected to the inside of the exhaust assembly 4 through a bellows 65; The exhaust assembly 4 drives the rust removal plate 61 to reciprocately rub the groove portion of the I-beam 1 through the guide assembly 5, and the exhaust assembly 4 extracts the air inside the exhaust plate 62 through the bellows 65; The scratch assembly 7 includes a guide rod 71 connected to the rust removal assembly 6 through two guide assemblies 5, a metal plate 75 is installed on the side of the guide assembly 5, and two guide blocks 73 are symmetrically installed on the side of the metal plate 75, each guide block 73 is provided with a guide groove 74, and a plastic rod 72 is hinged on the guide rod 71, and the upper and lower ends of the plastic rod 72 are respectively movable inside each guide groove 74; The rust removal assembly 6 drives the guide rod 71 to move back and forth through the guide assembly 5 , and the moving track of the guide rod 71 is perpendicular to the moving track of the rust removal plate 61 .

[0018] The above scheme is adopted: the device is preferably placed in the groove of the I-beam 1, and the wheel 3 is forced to roll on the ground and the bottom of the I-beam 1 respectively, and then the device is started, the wheel 3 drives the device to move as a whole, and the exhaust component 4 drives the rust removal plate 61 to move back and forth through the guide component 5, and scrapes the groove part of the I-beam 1, so that the more fragile rust can be removed in advance. It should also be noted that the exhaust component 4 will also extract the air in the baffle 63 through the bellows 65, so that the rust that falls off and the dust that falls due to vibration can be extracted into the inside of the baffle 63. In order not to affect the normal operation of the exhaust component 4, the rust will adhere to the filter plate 3 64; During the movement of the device, the metal plate 75 directly scrapes off the rust and dust on the groove of the I-beam 1, and the exhaust assembly 4 also drives the guide rod 71 to move back and forth through the guide assembly 5. The guide rod 71 pushes the plastic rod 72 to move back and forth in the guide groove 74. When the plastic rod 72 is pushed close to the groove part, it is guided away from the metal plate 75 according to the track of the guide groove 74. When the plastic rod 72 hits the inner wall of the groove, it is closely attached to the metal plate 75 according to the track of the guide groove 74 and the guide assembly 5 pulls back the plastic rod 72, so that rust and dust will not accumulate on the edge of the metal plate 75, further enhancing the dust removal efficiency of the device; After dust removal, the laser rust removal assembly 8 is directly started to remove rust from the I-beam.

[0019] like Figure 1-Figure 9 As shown, the exhaust assembly 4 includes an exhaust duct 41 installed on the side of the bracket 2 and located in the groove of the I-beam 1, and a motor 45 is installed inside the exhaust duct 41. The interior of the exhaust duct 41 has two independent upper and lower chambers, and the outer periphery of each chamber is respectively covered with a filter plate 44. The upper and lower ends of the output shaft of the motor 45 are respectively connected to a fan 46 located in each chamber.

[0020] The exhaust assembly 4 also includes an air inlet pipe 47 connected to the two chambers. The bellows 65 penetrates the exhaust pipe 41 and is connected to the air inlet pipe 47 . The output shaft of the motor 45 drives the fan 46 to rotate and generates suction in the air inlet pipe 47 .

[0021] The above solution is adopted: the motor 45 drives each fan 46 to rotate, which generates suction in the air inlet pipe 47, and extracts dust and rust dropped by the rust removal plate 61 through the bellows 65 and the exhaust plate 62. During the process of impurities being sucked, they will be adsorbed on the baffle 63, so that they will not move with the air and affect the operation of the fan 46; The wind generated by the rotation of the fan 46 will be blown outward through the two slots, and the dust and rust trapped in the exhaust pipe 41 will be blown onto the filter plate 2 44, so that they will not remain too much inside the exhaust pipe 41 and affect the connection between the filter plate 2 44 and the output shaft of the motor 45.

[0022] like Figure 1-Figure 5 As shown, the exhaust assembly 4 also includes an air intake plate 42 installed on the periphery of the exhaust pipe 41 and connected to the air intake pipe 47, the laser rust removal assembly 8 is installed on the side of the air intake plate 42, a filter plate 43 is installed on the outer side of the air intake plate 42, and an exhaust plate 48 connected to the two chambers is installed on the periphery of the exhaust pipe 41.

[0023] The exhaust plate 48 fits in with the groove portion of the I-beam 1 and is provided with an opening at the edge. The output shaft of the motor 45 drives the fan 46 to rotate and generates blowing force in the two chambers and the exhaust plate 48.

[0024] The above scheme is adopted: the wind force generated by the motor 45 driving the fan 46 outputs the blowing force to the exhaust plate 48 through the two chambers. At this time, the dust that cannot be sucked will be blown into the groove of the I-beam 1, and the suction force existing in the air intake pipe 47 will also extract the blown dust and rust through the air intake plate 42, but these impurities will be blocked by the filter plate 43 at the first time, so as to prevent them from affecting the normal operation of the device.

[0025] like Figure 1-Figure 9 As shown, the guide assembly 5 includes a supporting plate 51 installed on the top of the exhaust duct 41, and a gear 2 55 and two symmetrically arranged gears 1 54 are rotatably installed inside the supporting plate 51. Two first guide grooves 52 and second guide grooves 53 are respectively arranged on the top of the supporting plate 51. The exhaust assembly 4 is used to drive the gear 2 55 to rotate, and the gear 2 55 is respectively meshed with each gear 1 54.

[0026] The guide rod 71 moves inside the two first guide grooves 52 , and the guide rod 71 is eccentrically mounted to one of the gears 1 54 .

[0027] The rust removal plate 61 moves inside the two second guide grooves 53 , and the rust removal plate 61 is eccentrically mounted to the other gear 1 54 .

[0028] The above scheme is adopted: the output shaft of the motor 45 drives the gear 2 55 to rotate, and the gear 2 55 drives the two gears 1 54 to rotate. Since the guide rod 71 moves in the first guide groove 52, the rust removal plate 61 moves in the second guide groove 53, the first guide groove 52 and the second guide groove 53 are in a vertical state, and the guide rod 71 and the rust removal plate 61 are eccentrically installed on the top of each gear 1 54 respectively. At this time, the rust removal plate 61 and the guide rod 71 reciprocate simultaneously, but the moving trajectory will be in a vertical state, which will further not affect the smoothness of the operation of the device.

[0029] The working principle and use process of the present invention: The device is preferably placed in the groove of the I-beam 1, and the wheel 3 is forced to roll on the ground and the bottom of the I-beam 1 respectively. The wheel 3 drives the device to move as a whole, and the output shaft of the motor 45 drives the gear 2 55 to rotate, and the gear 2 55 drives the two gears 1 54 to rotate. Since the guide rod 71 moves in the first guide groove 52, the rust removal plate 61 moves in the second guide groove 53, the first guide groove 52 and the second guide groove 53 are vertical, and the guide rod 71 and the rust removal plate 61 are eccentrically installed on the top of each gear 1 54, and the rust removal plate 61 and the guide rod 71 move back and forth at the same time; The rust removal plate 61 scrapes against the groove of the I-beam 1, and the motor 45 drives each fan 46 to rotate, which generates suction in the air inlet pipe 47, and extracts dust and rust dropped by the rust removal plate 61 through the bellows 65 and the exhaust plate 62, and the rust will adhere to the filter plate 3 64; During the movement of the device, the metal plate 75 directly scrapes off the rust and dust on the groove of the I-beam 1, and the guide rod 71 reciprocates to push the plastic rod 72 to move in the guide groove 74. When the plastic rod 72 is pushed close to the groove part, it is guided away from the metal plate 75 according to the track of the guide groove 74. When the plastic rod 72 hits the inner wall of the groove, it is closely attached to the metal plate 75 according to the track of the guide groove 74 and the guide assembly 5 pulls back the plastic rod 72, so that rust and dust will not accumulate on the edge of the metal plate 75. The wind force generated by the motor 45 driving the fan 46 outputs the blowing force to the exhaust plate 48 through the two chambers. At this time, the dust that cannot be sucked will be blown into the groove of the I-beam 1, and the suction force in the air intake pipe 47 will also extract the blown dust and rust through the air intake plate 42, but these impurities will be blocked by the filter plate 43 at the first time; After dust removal, the laser rust removal assembly 8 is directly started to remove rust from the I-beam.
