Description

Technical Field

[0001] The utility model relates to the field of steel pipe rust removal, in particular to surface rust removal equipment for building steel pipes. Background Art

[0002] Rust removal of steel pipes is a common maintenance and repair work for steel pipe structures. During the placement process, steel pipes may be affected by oxidation, corrosion, etc., resulting in a rust layer on the surface of the steel pipe. If not handled in time, the rust layer will cause the mechanical properties of the steel pipe to deteriorate, thereby affecting the safety of the structure. Therefore, rust removal is required before the raw steel pipe is used.

[0003] Traditional steel pipe rust removal is usually carried out by chemical spraying or grinding. Chemical spraying is not conducive to the service life of the steel pipe, while the traditional grinding method is inefficient. In addition, due to the cylindrical shape of the steel pipe, it is difficult to perform all-round grinding on the surface of the smooth pipe, which has poor practicality. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, a surface rust removal device for building steel pipes includes a workbench 1, a motor 2 is fixedly installed at a rear position on one side of the upper part of the workbench 1, a feeding structure 3 is fixedly installed at a center position on one side of the upper part of the workbench 1, the feeding structure 3 includes a base 4, a gear 6 is rotatably installed inside the base 4, the gear 6 is fixedly connected to the output shaft of the motor 2, a clamping wheel 5 is slidably installed at an upper position inside the base 4, a dust cover 11 is bolted to the upper part of the workbench 1 on one side of the base 4, and a grinding structure 10 is arranged inside the dust cover 11;

[0022] The grinding structure 10 includes two bearing seats 14, a second motor 19 and two turntables 15. The two bearing seats 14 are symmetrically fixedly connected to the workbench 1, one of the bearing seats 14 is rotatably connected to a belt pulley through a hollow shaft, and the other bearing seat 14 is fixedly connected to a gear second 17 through a hollow shaft. Two groups of wire wheels 16 of different sizes are connected between the two turntables 15, and the number of wire wheels 16 in each group is two. One end of the two small-sized wire wheels 16 is fixedly connected to a gear three 18, and the gear three 18 is meshed with the gear two 17. The other ends of the four wire wheels 16 all pass through the turntable 15 and are connected to a limiting disk, and a belt is connected between the limiting disks of a group of one large and one small wire wheels 16. The second motor 19 is fixedly installed at the bottom of the workbench 1, and the output shaft of the second motor 19 is connected to the belt pulley through a belt.

[0023] In this embodiment, a dust outlet is provided at the lower part of the dust cover 11 on the workbench 1 , and a feeding structure 3 is also provided on one side of the dust cover 11 .

[0024] Two feeding structures 3 are provided so that the steel pipe can pass through the base 4 faster. The motor 2 can simultaneously drive the gears 6 of the two feeding structures 3 to rotate, thereby increasing the stability of the steel pipe when it is moving forward.

[0025] In this embodiment, feed openings are provided on both sides of the dust cover 11 at the center of the two bases 4 .

[0026] The feed port serves to introduce the steel pipe.

[0027] In this embodiment, a fixed block 8 is fixedly installed at the front of the base 4, and the fixed block 8 passes through the center position and is threadedly connected to a screw rod 9. The top end of the screw rod 9 is rotatably connected to a movable block 7, and the rear of the movable block 7 passes through the base 4 and is rotatably connected to the clamping wheel 5.

[0028] When the screw rod 9 rotates, it is constrained by the fixed block 8, driving the movable block 7 to move. Since the movable block 7 passes through the front part of the base 4 and is fixedly connected with the clamping wheel 5, the clamping wheel 5 also starts to slide inside the base 4, so that the distance between the clamping wheel 5 and the gear 1 6 can be adjusted to adapt to the steel pipe raw materials of different diameters that need to pass through.

[0029] The lower part of the motor 2 19 is fixedly connected with a collecting box 12, and the front part of the collecting box 12 is hingedly connected with a cover 13.

[0030] The collecting box 12 can receive the fallen rust dust, and the cover 13 can facilitate the cleaning of the staff.

[0031] It should be noted that the utility model is a surface rust removal device for construction steel pipes. When in use, according to the diameter of the construction steel pipe, the screws 9 of the two feeding structures 3 are rotated so that the screws 9 drive the two movable blocks 7 to move in the vertical direction, thereby adjusting the spacing between the two clamping wheels 5 and the two gears 6, so as to adapt to construction steel pipes of different diameters;

[0032] Then place the construction steel pipe between the card wheel 5 and the gear 6, start the motor 2, the motor 2 drives the gear 6 to rotate, and the gear 6 cooperates with the card wheel 5 to transport the steel pipe to move;

[0033] The steel pipe passes through the feed port of the dust cover 11, one of the bearing seats 14, and the hollow shaft in sequence and then enters between the four wire wheels 16. At this time, the motor 2 19 drives the belt pulley to rotate through the belt, and the belt pulley drives one of the turntables 15 to rotate through the hollow shaft. The turntable 15 drives the four wire wheels 16 to revolve, and at the same time, the other turntable 15 follows the rotation;

[0034] Since gear two 17 is fixed and gear three 18 revolves outside gear two 17, gear three 18 will also rotate during the process. During the rotation, since gear three 18 is connected to the small-sized wire wheel 16, the small-sized wire wheel 16 will also rotate during the process. The small-sized wire wheel 16 and the large-sized wire wheel 16 are driven by a limit plate and a belt. Therefore, the four wire wheels 16 can all revolve during the rotation. During the process, the wire wheel 16 grinds off the rust on the surface of the building steel pipe, achieving the effect of rapid rust removal.

[0035] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
