Description

Technical Field

[0001] This utility model relates to the technical field of sandblasting and rust removal equipment, specifically to a rust removal mechanism for steel column beams using sandblasting. Background Technology

[0002] A sandblasting machine is a mechanical device that uses compressed air to propel abrasive materials (metallic and non-metallic) onto the surface of a workpiece.

[0003] Chinese Patent Publication No. CN216504407U discloses an automatic sandblasting machine, including a frame, a first dust removal chamber, a second dust removal chamber, a sandblasting chamber, a conveyor belt, and a spray gun assembly. The frame has a first end and a second end. The first dust removal chamber is located at the first end and has a first exhaust port for connecting to an exhaust system. The second dust removal chamber is located at the second end and has a second exhaust port for connecting to the exhaust system. The sandblasting chamber is located between the first and second dust removal chambers on the frame. The conveyor belt spans between the first and second ends to transport workpieces sequentially through the first dust removal chamber, the sandblasting chamber, and the second dust removal chamber. The spray gun assembly is suspended within the sandblasting chamber and adapted to connect to a compressed air pipe for sandblasting workpieces entering the sandblasting chamber. According to the embodiments of this utility model, the automatic sandblasting machine utilizes an exhaust system to remove dust generated during the sandblasting process, reducing dust accumulation. Furthermore, it boasts high working efficiency.

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.

[0051] Example 1:

[0052] like Figures 1 to 6As shown, this utility model provides a steel column beam sandblasting rust removal mechanism, including: a sandblasting machine housing 1 for using the mechanism, a water-sand mixing tank 101 and a booster pump 102 arranged on one side of the sandblasting machine housing 1, a permeable conveyor belt 107 arranged inside the sandblasting machine housing 1, a steel beam 105 gradually entering the sandblasting machine housing 1 through the permeable conveyor belt 107 and an auxiliary conveyor table 106, and sandblasting rust removal is achieved inside the sandblasting machine housing 1 using a sandblasting gun 104, which is arranged on a mounting frame 103 for sandblasting. Gun 104 is mounted on mounting bracket 103 and is used for mounting clamping structure of sandblasting gun 104. Adjustment mechanism is mounted on clamping mechanism for adjusting angle of sandblasting gun 104. Movable maintenance mechanism is mounted on sandblasting machine housing 1 for assisting in maintenance and replacement of sandblasting gun 104. The clamping mechanism is also equipped with connecting components for mounting and fitting the clamping mechanism position.

The sandblasting gun 104 can also rotate on the mounting base 2 through the T-shaped hole 3 and the T-shaped rotating block 301. When the angle of the sandblasting gun 104 is appropriate, the T-shaped rotating block 301 can be fixed by three sets of limiting bolts 302 to restrict its continued rotation.

[0056] Specifically, the auxiliary components include auxiliary conveyor platforms 106 arranged on both sides of the sandblasting machine housing 1 to support the moving position of the steel beam 105, so that the steel beam 105 gradually enters the sandblasting machine housing 1 through the permeable conveyor belt 107 and the auxiliary conveyor platform 106.

[0057] Example 2:

[0058] Based on Example 1, in order to facilitate the daily maintenance and repair of the device, the mounting frame can be moved to the outside of the sandblasting machine housing for maintenance via the movable base.

[0059] Specifically, the movable maintenance mechanism includes a maintenance sleeve 4 arranged on the sandblasting machine housing 1, a movable base 401 arranged on the bottom side of the maintenance sleeve 4, a sliding groove 402 formed on the inner walls of both sides of the maintenance sleeve 4, a slider 403 arranged in the sliding groove 402 to allow the movable base 401 to slide in the bottom position of the maintenance sleeve 4 in cooperation with the sliding groove 402, the movable base 401 can move in the maintenance sleeve 4 through the sliding groove 402 and the slider 403, and the movable base 401 and the mounting bracket 103 can be moved to the outside of the equipment for the convenience of maintenance personnel outside the equipment, a positioning piece 404 formed on the movable base 401 and the sandblasting machine housing 1, a positioning bolt 405 arranged on the positioning piece 404 to fix the position of the movable base 401 in cooperation with the positioning piece 404, and the positioning piece 404 and the positioning bolt 405 to release the restriction of the position of the movable base 401 by the positioning piece 404 and the positioning bolt 405.

[0060] Specifically, the observation component includes an active observation and maintenance window 406 arranged on the side of the sandblasting machine housing 1 for observing the internal state of the sandblasting machine housing 1 and for adjusting and maintaining the equipment. Opening the active observation and maintenance window 406 facilitates equipment maintenance.

[0061] Example 3:

[0062] Based on Example 1, in order to reduce the waste of resources, waste sand and wastewater generated during sandblasting operations are collected together using a collection hopper and a waste recovery pump.

[0063] Specifically, a collection hopper 5 is arranged on the bottom side of the sandblasting machine housing 1, and a waste recovery pump 501 is arranged on the bottom side of the collection hopper 5. Wastewater and waste sand generated during the cleaning process are collected by the collection hopper 5 at the bottom of the equipment and transported to a suitable location for storage by the waste recovery pump 501.

[0064] Working principle: When using this equipment, the steel beam 105 is first placed in the middle of the auxiliary conveyor table 106, so that the steel beam 105 gradually enters the sandblasting machine housing 1 through the permeable conveyor belt 107 and the auxiliary conveyor table 106. Inside the sandblasting machine housing 1, sandblasting and rust removal are achieved using sandblasting guns 104. To ensure the effectiveness of sandblasting and rust removal, an appropriate number and angle of sandblasting guns 104 need to be arranged on the mounting frame 103. The mounting base 2 for mounting the sandblasting guns 104 can be arranged in a suitable position using connecting plates 203 and connecting bolts 204. The position of the sandblasting gun 104 is such that it can rotate on the mounting base 2 through the T-hole 3 and the T-rotating block 301. When the angle of the sandblasting gun 104 is appropriate, the T-rotating block 301 can be fixed by three sets of limit bolts 302 to restrict its continued rotation, so that the sandblasting gun 104 can perform sandblasting at the appropriate position and angle, ensuring thorough cleaning of the bending part and vertical surface of the steel beam 105. The wastewater and waste sand generated during the cleaning process are collected by the collection hopper 5 at the bottom of the equipment and transported to the appropriate location for storage by the waste material recovery pump 501.

[0065] When the sandblasting gun 104 malfunctions, the movable observation and maintenance window 406 can be opened to release the restriction of the positioning plate 404 and positioning bolt 405 on the position of the movable base 401. At this time, the movable base 401 can move within the maintenance sleeve 4 through the sliding groove 402 and the slider 403, moving the movable base 401 and the mounting bracket 103 to the outside of the equipment. This allows maintenance personnel to remove and replace the sandblasting gun 104 from outside the equipment by loosening the arc-shaped mounting sleeve 201 and the mounting sleeve connecting bolt 202. The cooperation between the arc-shaped mounting sleeve 201 and the mounting sleeve connecting bolt 202 makes the installation and removal of the sandblasting gun 104 simple and quick.

[0066] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
