[0002] Deburring is a common processing procedure for hot-dip galvanized steel structural parts. In actual production, burr removal of steel structural parts is usually carried out by combining large-scale grinding machines and small-scale manual grinding equipment. Large-scale grinding machines have high efficiency in deburring, while small-scale grinding equipment is more flexible and more suitable for small production environments.

[0003] The Chinese utility model patent application number is 202023205264.0. It is a hot-dip galvanized workpiece deburring auxiliary device. The cleaning disc is driven by a motor to rotate so that the brush on the cleaning disc cleans the burrs on the surface of the hot-dip galvanized workpiece, which has the effect of removing the burrs generated on the hot-dip galvanized workpiece after galvanizing.

[0004] In view of the above-mentioned prior art, the inventor believes that burrs on circular steel structures generally appear at their ends, but steel structures are usually placed on the ground, which makes it difficult to touch the part of the steel structure that contacts the ground. When using small grinding equipment for grinding, it is necessary to lift the end of the steel structure, which is quite laborious. Therefore, the present application aims to propose a hot-dip galvanized steel structure deburring auxiliary device, the purpose of which is to facilitate the lifting of one end of the steel structure and lift it off the ground when grinding, thereby facilitating the grinding of the burrs on its end.

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-3 The specific implementation modes of the present utility model are further described in detail.

[0021] Embodiment 1

[0022] A hot-dip galvanized steel structural member deburring auxiliary device comprises a bracket 10, a truss 20 vertically slidably mounted on the bracket 10, L-shaped clamps 30 horizontally slidably mounted at both ends of the truss 20, and a power mechanism 40 arranged at the top of the bracket 10 for driving the truss 20 to move upward. The two L-shaped clamps 30 can hold the circular steel structural member from both sides of the bottom. When the truss 20 is driven to move upward by the power mechanism 40, the two L-shaped clamps 30 can hold the circular steel structural member, so that one end of the circular steel structural member is off the ground, which is convenient for use. The grinding equipment is used to grind the ends of the structural members. Furthermore, two adjusting blocks 31 are horizontally slidably provided on the truss 20. The upper ends of the two L-shaped clamps 30 are rotatably connected to the two adjusting blocks 31 respectively, and a fixing structure for fixing the L-shaped clamps 30 is provided on the adjusting blocks 31. The L-shaped clamps 30 are slidably connected to the truss 20 through the adjusting blocks 31, so that the distance between the two L-shaped clamps 30 can be adjusted easily. In addition, since the L-shaped clamps 30 are rotatably connected to the adjusting blocks 31, the two L-shaped clamps 30 can be easily rotated from both sides to clamp the circular steel structure.

[0023] When in use, first slide and adjust the distance between the two adjustment blocks 31 according to the diameter of the circular steel structure, then move the bracket 10 to the position of the steel structure that needs to be polished, so that the two L-shaped jaws 30 are located on both sides of the circular steel structure, and then fix the two L-shaped jaws 30 through the fixed structure, and drive the two L-shaped jaws 30 to move upward through the power mechanism 40, so as to lift one end of the circular steel structure off the ground. In this way, it is convenient to use small polishing equipment to polish the end of the steel structure, which plays a good auxiliary role.

[0024] The bracket 10 is a gantry structure, and rollers are installed on both sides of the lower end of the bracket 10 to facilitate the overall movement of the bracket 10.

[0025] The truss 20 is fixed with a horizontally arranged transverse slide rail 21, and the adjusting block 31 is slidably connected to the transverse slide rail 21. A two-way threaded rod 22 is rotatably arranged inside the transverse slide rail 21, and the two ends of the two-way threaded rod 22 are respectively threadedly connected to the two adjusting blocks 31. By manually rotating the two-way threaded rod 22, the two adjusting blocks 31 can be driven to approach or move toward each other, so as to adjust the distance between the two L-shaped clamps 30, thereby facilitating the clamping of circular steel structures of different diameters. In order to quickly locate the position of the adjusting block 31, a ruler can also be fixed on the slide rail 21.

[0026] Furthermore, in order to prevent the L-shaped clamp 30 from scratching the surface of the steel structure, the L-shaped clamp 30 includes a clamping rod 301 and a lifting plate 302. The upper end of the clamping rod 301 is rotatably connected to the adjustment block 31, and the lifting plate 302 is rotatably connected to the lower end of the clamping rod 301. In this way, when one end of the steel structure is lifted, the lifting plate 302 will also rotate with the circular steel structure, and maintain linear contact with the side of the circular steel structure, thereby avoiding friction. If the lifting plate 302 and the clamping rod 301 are fixedly connected, when the steel structure is lifted, the steel structure will rotate between the lifting plate 302, thereby causing friction, which can easily scratch the surface of the steel structure. In order to further prevent the problem of scratching, a rubber block can also be fixed on the surface of the lifting plate 302.

[0027] Specifically, the adjusting block 31 is fixed with a fixed shaft 32 , the upper end of the clamping rod 301 is rotatably connected to the fixed shaft 32 , the clamping rod 301 and the adjusting block 31 are penetrated by a fixing hole, and a fixing pin 33 is inserted into the fixing hole as a fixing structure for fixing the L-shaped clamping claw 30 .

[0028] A vertical slide rail 11 is fixed to the upper end of the bracket 10 , and both ends of the truss 20 are slidably connected to the vertical slide rail 11 .

[0029] In this embodiment, the power mechanism 40 is a screw 41a, which is rotatably connected to the upper end of the vertical slide rail 11, and the lower end of the screw 41a is threadedly connected to the truss 20. A handwheel is fixed to the upper end of the screw 41a to facilitate rotating the screw 41a through the handwheel.

[0030] Embodiment 2

[0031] The structure of the second embodiment is roughly the same as that of the first embodiment, except that the power mechanism 40 is a cylinder 41b, which is fixed to the upper end of the vertical slide rail 11, and the telescopic end of the cylinder 41b is fixedly connected to the truss 20. By setting the cylinder 41b, no manual operation is required, and it is more labor-saving to use.

[0032] A hot-dip galvanized steel structure deburring auxiliary device, the working principle is as follows:

[0033] First, according to the diameter of the circular steel structure, manually rotate the bidirectional threaded rod 22 to adjust the distance between the two L-shaped jaws 30, then move the bracket 10 to the position of the steel structure, so that the two L-shaped jaws 30 are on both sides of the steel structure and the L-shaped jaws 30 are fixed by the fixed structure, and then the truss 20 is driven upward by the power mechanism 40, so that the two L-shaped jaws 30 hold one end of the circular steel structure and leave it off the ground, so that the end of the structure can be polished using a small polishing equipment.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
