The elevator support beam not only supports the traction machine, but also includes the car, load, counterweight, cables, wire ropes, etc., all of which are suspended on the support beam through the traction machine. It can be said that a thousand pounds are held in one beam.

[0003] Conventional elevator load-bearing beams often use I-beams as the main structure. To ensure the long-term stable use of I-beams in elevator load-bearing beams, they need to be painted for corrosion protection.

[0023] This invention also discloses a method for corrosion protection of elevator load-bearing beams, specifically including the following steps:

[0024] Step 1, Conveying: Start the drive motor, which drives the drive shaft to rotate the drive roller. During the rotation of the drive shaft, the driven shaft is driven to rotate through the first belt assembly. The driven shaft drives the adjacent driven shaft to rotate through the second belt assembly. The driven shaft drives the auxiliary roller to rotate. When a driven shaft away from the drive shaft rotates, it drives the guide shaft through the third belt assembly to rotate the second guide roller. After the concave part of the I-shaped elevator load-bearing beam is placed on the second guide roller on the left side with the concave part facing up, the I-shaped elevator load-bearing beam moves through the material inlet to the auxiliary roller in the processing box under the rotation drive of the second guide roller. After passing through the drive roller and several auxiliary rollers in sequence, the I-shaped elevator load-bearing beam passes through the second guide roller on the right side and gradually moves out of the processing box.

[0025] Step 2, Limiting: Start the adjusting motor, the adjusting motor drives the adjusting gear to rotate, the adjusting gear drives the toothed rack to move, the toothed rack drives the fixed plate to move, the fixed plate drives the two square plates to move along the feed opening, the square plates drive the first guide roller to move to the width dimension of the I-shaped elevator load-bearing beam, and limit the I-shaped elevator load-bearing beam;

[0027] Step 4, Rust Removal from the Recess: Before starting the drive motor in Step 1, select the number of groove grinding rollers according to the size of the recess in the I-beam elevator load-bearing beam. When adjusting the number of groove grinding rollers, unscrew the nut on the front side, remove the shims and groove grinding rollers, first put the set number of shims on the spline column, then put the adjusted number of groove grinding rollers on the spline column, so that the groove grinding rollers correspond to the recess in the I-beam elevator load-bearing beam. Then put the shims on the spline column, squeeze the groove grinding rollers, and tighten the nut. At the same time as starting the drive motor in Step 1, start the grinding motor. The grinding motor drives the spline column to rotate the groove grinding rollers.

[0031] (2) By utilizing the setting of adjusting gear and toothed rack, the two fixed plates can be pulled to move in an arc shape or move away from each other during the rotation of the adjusting gear. With the cooperation of square plate, material outlet and auxiliary roller, the fixed plate drives the square plate to move back and forth stably, thereby realizing the centering and limiting of the I-shaped elevator load-bearing beam on the auxiliary roller and active roller, providing convenient conditions for subsequent side grinding and concave grinding. By using the setting of vertical grinding roller, after the two square plates drive the first guide roller to limit the I-shaped elevator load-bearing beam, the vertical grinding roller can be in close contact with the side of the I-shaped elevator load-bearing beam, thereby realizing the side rust removal of the I-shaped elevator load-bearing beam.

[0032] (3) The present invention uses the combination of a fan, a main air duct and an inclined air duct to blow off the waste debris after grinding on the I-shaped elevator load-bearing beam. By controlling the air volume of the fan, the purpose of blowing the waste debris into the garbage drawer can be achieved.

[0033] (4) The present invention uses a whole composed of several grooved grinding rollers as the grinding structure for the recess of the I-shaped elevator load-bearing beam. With the cooperation of nuts, washers, spline columns and grooved grinding rollers, the overall size of the whole composed of several grooved grinding rollers can be adjusted, which can better adapt to the rust removal of I-shaped elevator load-bearing beams of different sizes.

[0053] A method for corrosion protection of elevator load-bearing beams includes the following steps:

[0054] Step 1, Conveying: Start the drive motor 17. The drive motor 17 drives the drive shaft 18 to rotate the drive roller 7. During the rotation of the drive shaft 18, the driven shaft 19 is driven to rotate via the first belt assembly 20. This driven shaft 19 drives the adjacent driven shaft 19 to rotate via the second belt assembly 21. The driven shaft 19 drives the auxiliary roller 6 to rotate. When the driven shaft 19 away from the drive shaft 18 rotates, it drives the guide shaft 24 via the third belt assembly 25 to rotate the second guide roller 23. The concave part of the I-shaped elevator load-bearing beam is placed on the second guide roller 23 on the left side with the concave part facing upwards. (Specifically, the...) After the I-beam elevator load-bearing beam rotates 90° clockwise or counterclockwise, both sides of the I-beam elevator load-bearing beam become flat, and are polished and rusted by the vertical grinding roller 31. The top and bottom of the I-beam elevator load-bearing beam are concave, and are polished and rusted by the grooved grinding roller 35. Driven by the rotation of the second guide roller 23, the I-beam elevator load-bearing beam moves through the material outlet 2 to the auxiliary roller 6 in the processing box 1. After passing through the drive roller 7 and several auxiliary rollers 6 in sequence, the I-beam elevator load-bearing beam passes through the second guide roller 23 set on the right side and gradually moves out of the processing box 1.

[0055] Step 2, Limiting: Start the adjusting motor 12, the adjusting motor 12 drives the adjusting gear 13 to rotate, the adjusting gear 13 drives the toothed rack 16 to move, the toothed rack 16 drives the fixed plate 15 to move, the fixed plate 15 drives the two square plates 14 to move along the feed port 2, the square plates 14 drive the first guide roller 5 to move to the width dimension of the I-shaped elevator load-bearing beam, and limit the I-shaped elevator load-bearing beam;

[0056] Step 3, side rust removal: At the same time as the drive motor 17 starts in step 1, the side motor 30 is started. The side motor 30 drives the vertical grinding roller 31 to grind and remove rust from the side of the I-shaped elevator load-bearing beam.

[0057] Step 4, Rust Removal from the Notch: Before starting the drive motor 17 in Step 1, select the number of groove grinding rollers 35 according to the notch size of the I-beam elevator load-bearing beam. When adjusting the number of groove grinding rollers 35, unscrew the nut 34 on the front side, remove the shims 36 and groove grinding rollers 35, first insert the set number of shims 36 onto the spline column 33, and then insert the adjusted number of groove grinding rollers 35 onto the spline column 33, so that the groove grinding rollers 35 are in contact with the I-beam elevator load-bearing beam.

At the same time as the drive motor 17 is started in step one, the grinding motor 32 is started. The grinding motor 32 drives the spline column 33 to rotate the groove grinding roller 35. During the movement of the I-shaped elevator load-bearing beam, the spring 43 squeezes the U-shaped frame 39, so that the groove grinding roller 35 fits against the notch of the I-shaped elevator load-bearing beam to grind and remove rust from the notch of the I-shaped elevator load-bearing beam.

[0058] Step 5, Dust Removal: While the drive motor 17 starts in Step 1, the fan 26 is also started.

6. A method for anti-corrosion treatment of elevator load-bearing beams, applied to the anti-corrosion treatment device for elevator load-bearing beams as described in claim 1, characterized in that: The method specifically includes the following steps: Step 1, Conveying: Start the drive motor (17). The drive motor (17) drives the drive shaft (18) to rotate the drive roller (7). During the rotation of the drive shaft (18), the driven shaft (19) is driven to rotate through the first belt assembly (20). The driven shaft (19) drives the adjacent driven shaft (19) to rotate through the second belt assembly (21). The driven shaft (19) drives the auxiliary roller (6) to rotate. When a driven shaft (19) away from the drive shaft (18) rotates, it is driven to rotate through the third belt assembly (25). The second guide roller (23) is rotated by the shaft (24), and the concave part of the I-shaped elevator load-bearing beam is placed on the second guide roller (23) on the left side. Driven by the rotation of the second guide roller (23), the I-shaped elevator load-bearing beam moves through the material port (2) to the auxiliary roller (6) in the processing box (1). After passing through the drive roller (7) and several auxiliary rollers (6) in sequence, the I-shaped elevator load-bearing beam gradually moves out of the processing box (1) after passing through the second guide roller (23) on the right side. Step 2, Limiting: Start the adjusting motor (12), the adjusting motor (12) drives the adjusting gear (13) to rotate, the adjusting gear (13) drives the toothed rack (16) to move, the toothed rack (16) drives the fixed plate (15) to move, the fixed plate (15) drives the two square plates (14) to move along the feed inlet (2), the square plates (14) drive the first guide roller (5) to move to the width dimension of the I-shaped elevator load-bearing beam, and limit the I-shaped elevator load-bearing beam; Step 3, side rust removal: At the same time as the drive motor (17) starts in step 1, the side motor (30) is started. The side motor (30) drives the vertical grinding roller (31) to grind and remove rust from the side of the I-shaped elevator load-bearing beam. Step 4, Rust Removal from the Notch: Before starting the drive motor (17) in Step 1, select the number of groove grinding rollers (35) according to the notch size of the I-beam elevator load-bearing beam. When it is necessary to adjust the number of groove grinding rollers (35), unscrew the nut (34) set on the front side, remove the shims (36) and groove grinding rollers (35), first put the set number of shims (36) on the spline column (33), and then put the adjusted number of groove grinding rollers (35) on the spline column (33) so that the groove grinding rollers (35) are in contact with the notch of the I-beam elevator load-bearing beam. After the openings are aligned, a washer (36) is placed on the spline column (33), the groove grinding roller (35) is squeezed and then the nut (34) is tightened. At the same time as the drive motor (17) is started in step one, the grinding motor (32) is started. The grinding motor (32) drives the spline column (33) to make the groove grinding roller (35) rotate. During the movement of the I-shaped elevator load-bearing beam, the spring (43) squeezes the U-shaped frame (39) so that the groove grinding roller (35) fits against the groove of the I-shaped elevator load-bearing beam to grind and remove rust from the groove of the I-shaped elevator load-bearing beam. Step 5, cleaning: At the same time as the drive motor (17) starts in step 1, the fan (26) is started. The fan (26) blows air into several inclined air ducts (28) through the main air duct (27), so that the inclined air ducts (28) blow down the waste debris from the grinding on the I-shaped elevator load-bearing beam and into the garbage drawer (29).
