Description

Technical Field

[0001] This utility model relates to the field of steel structure surface treatment technology, specifically a shot blasting machine for steel structure surface treatment. Background Technology

[0002] Shot blasting machines use high-speed shot blasters to evenly apply shot onto the surface of workpieces, achieving cleaning and rust removal. Shot blasting machines can simultaneously remove sand, cores, and clean castings. In some regions, they are also colloquially called sandblasting machines or sandblasting machines. For large steel structure workpieces, they need to be hoisted onto a conveyor table and then transported to the shot blasting chamber for shot blasting treatment.

[0003] In traditional shot blasting machines for steel structure surface treatment, the shot blaster is usually fixed during use, and its angle cannot be adjusted back and forth in the vertical direction during spraying. This affects the overall uniformity of shot blasting on the steel structure surface and reduces the efficiency of the device.

[0004] For example, patent application number 202323163798.5 discloses a shot blasting machine for steel structure surface treatment. A utility model discloses a shot blasting machine for steel structure surface treatment, including a conveyor table and a support rod at the bottom of the conveyor table. Shot blasting boxes are provided on both the front and rear sides of the conveyor table, and inverted U-shaped connecting frames that can move up and down are provided on the inner walls of both the front and rear sides of the shot blasting boxes. This utility model allows for reciprocating up-and-down adjustment of the angles of multiple shot blasters during use, thereby ensuring the overall uniformity of shot blasting and improving the efficiency of the device. However, when this shot blasting machine is used for steel structure surface treatment, the ejected steel shot generates a certain impact, causing the rotating roller to move the steel structure, affecting the shot blasting effect. Simultaneously, shot blasting also causes wear on the rotating roller.

[0005] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a shot blasting machine for steel structure surface treatment. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-3As shown, a shot blasting machine for surface treatment of steel structures includes a shot blasting machine body 1. A drive frame 101 is provided on the inner surface of the shot blasting machine body 1, and a drive roller 102 is rotatably mounted on the inner surface of the drive frame 101. A collection box 103 is installed on the outer surface of the drive roller 102, and a placement plate 104 is installed on the upper surface of the collection box 103. This technical solution, by setting the placement plate 104, can collect the shot blasting, avoiding contact between the shot and the outer surface of the drive roller 102, thus preventing wear of the drive roller 102.

[0025] Furthermore, a servo controller 2 is provided on one side surface of the shot blasting machine body 1, and an infrared position sensor 201 is provided on the rear surface of the shot blasting machine body 1. This technical solution allows the position of the collection box 103 to be detected by setting the infrared position sensor 201.

[0026] Furthermore, a placement frame 202 is provided on the lower surface of the drive frame 101, and a stabilizing seat 203 is provided on the upper surface of the placement frame 202. A hydraulic push rod 204 is installed on the upper surface of the stabilizing seat 203. With this technical solution, the hydraulic push rod 204 can be installed directly below the shot blasting machine body 1 through the placement frame 202, which makes it easy to push the collection box 103 up.

[0027] Furthermore, the upper surface of the hydraulic push rod 204 is provided with a contact plate 205, and the contact plate 205 is located directly below the shot blasting machine body 1. The upper surface of the contact plate 205 is in contact with the lower surface of the collection box 103. With this technical solution, after the infrared positioner 201 detects that the collection box 103 with the steel structure has entered the shot blasting machine body 1, the hydraulic push rod 204 can be driven to make the contact plate 205 contact the lower surface of the collection box 103 and push the collection box 103 up. This can improve the placement stability of the steel structure during shot blasting and avoid rolling friction between the collection box 103 and the drive roller 102 during shot blasting, which would affect the cleaning effect of the steel structure.

[0028] like Figure 4 As shown, support plates 3 are provided on both sides of the upper surface of the shot blasting machine body 1, and a servo drive rod 301 is rotatably mounted on the inner surface of the support plate 3. An eccentric wheel 302 is provided on the outer surface of the servo drive rod 301, and the servo drive rod 301 is driven by a servo motor. In this technical solution, the eccentric wheel 302 can drive the return spring 306 to reciprocate and compress, so that the shot blasting nozzle installed on the sliding frame 307 can reciprocate and clean the steel structure.

[0029] Furthermore, a limiting slide rod 303 is slidably installed through the upper surface of the shot blasting machine body 1, and a sliding frame 307 is provided on the lower surface of the limiting slide rod 303. A threaded groove 304 is provided on the upper outer surface of the limiting slide rod 303, and an adjusting pressure sleeve 305 is spirally installed on the outer surface of the threaded groove 304. A return spring 306 is provided on the outer surface of the limiting slide rod 303, and the upper end of the return spring 306 is frictionally connected to the lower surface of the adjusting pressure sleeve 305. The adjusting pressure sleeve 305 is located directly below the eccentric wheel 302, and the eccentric wheel 302 and the adjusting pressure sleeve 305 are in contact connection. In this technical solution, by setting the adjusting pressure sleeve 305, the speed of the return spring 306 can be controlled by pressing down along the threaded groove 304, thereby controlling the fixed-point spraying time of the shot blasting nozzle on the sliding frame 307 according to the cleaning requirements of the steel structure, thus improving the cleaning effect of the steel structure.

[0030] Working Principle: When using this shot blasting machine for steel structure surface treatment, the steel structure workpiece is first placed stably on the upper surface of the placement plate 104 of the collection box 103. The drive roller 102 drives the collection box 103 to move forward at a constant speed along the track through friction transmission. When the collection box 103 triggers the sensing signal of the infrared positioner 201, the servo controller 2 responds immediately, controlling the hydraulic push rod 204 to extend precisely, pushing the contact plate 205 to smoothly lift the collection box 103. As the collection box 103 is lifted away from the surface of the drive roller 102, a non-contact isolation is formed, effectively avoiding the impact and wear of steel shot on the roller surface during shot blasting.

[0031] At this moment, the servo motor receives the command and starts, driving the servo drive rod 301 to rotate at high speed, which in turn drives the eccentric wheel 302 to rotate synchronously. The centrifugal force of the eccentric wheel 302 periodically presses down on the adjusting sleeve 305, and the reciprocating motion is precisely transmitted to the sliding frame 307 via the limiting slide rod 303. The sliding frame 307 drives the shot blasting nozzle to perform regular reciprocating p-jetting, ensuring that the steel shot is blasted onto the steel structure surface at the optimal angle and force, achieving efficient rust removal and surface strengthening treatment.

[0032] After blasting, the steel shot falls into the collection box 103 through the sieve holes of the slotted plate 104 under the influence of gravity. This slotted plate is made of high-strength mesh, and its aperture design ensures rapid descent and recovery of the steel shot while preventing workpiece displacement. Combined with the fully enclosed collection box 103, this forms a highly efficient circulating shot recovery system. This significantly reduces steel shot loss and prevents continuous wear on the drive roller 102 and track components caused by scattered steel shot, effectively extending the equipment's service life. This is the working principle of the shot blasting machine used for steel structure surface treatment.
