Description

Technical Field

[0001] This utility model relates to the field of steel bar rust removal technology, specifically to a steel bar grinding and rust removal device. Background Technology

[0002] In the construction industry, steel bars are an important construction material. They work in conjunction with concrete to enhance the structural strength of the concrete. Most steel bars have a circular cross-section. However, in actual reinforced concrete construction sites, it is inevitable to come into contact with a large number of steel bars with rust on their surface. Before construction, steel bar workers need to remove the rust from the surface of the required steel bars. The quality and efficiency of rust removal directly affect the overall construction quality and progress. Manual rust removal of steel bars is time-consuming and labor-intensive. Workers are prone to hand injuries during the rust removal process, and the effect of manual rust removal is not ideal.

[0003] The existing invention with patent number CN108608295A discloses an industrial steel bar rust removal device. This invention can clamp and fix the steel bar from both ends according to its length, which is convenient and stable. By reversing the motor, the rust removal device is controlled to make reciprocating linear motion, thereby continuously rubbing and removing rust. However, in this solution, the steel bar and the whetstone used to grind the steel bar do not rotate relative to each other during the rust removal process, which makes it easy for the steel bar to be incompletely rusted. As a result, rust residue is likely to appear on the outer wall of the steel bar, requiring workers to remove the rust again afterward, which is time-consuming and laborious. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a steel bar grinding and rust removal device, which solves the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A steel bar grinding and rust removal device is provided, which includes a frame, a rotating ring that can rotate freely is limited at one end of the frame and is connected to a drive motor, the rotating ring is connected to a grinding ring located in the middle through a plurality of first connecting rods, a plurality of grinding plates for clamping and grinding steel bars are provided inside the grinding ring, and a fixing member for limiting and fixing the steel bars is movably provided on the frame, and the fixing member is set on a linear reciprocating mechanism and moves linearly reciprocating along the extension direction of the steel bars.

[0007] Furthermore, a slip ring is provided at one end of the rotating ring, and slide blocks are provided on both sides of the frame, with slide grooves on the slide blocks that slide in conjunction with the slip ring.

[0008] Furthermore, the slip ring has an L-shaped cross-section, and the slip groove is an arc-shaped groove with an L-shaped cross-section.

[0009] Furthermore, the outer wall of the rotating ring is provided with several gear teeth in the circumferential direction, and the shaft of the drive motor is provided with a drive gear that meshes with the several gear teeth.

[0010] Furthermore, the fastener includes a horizontal sleeve coaxially arranged with the grinding ring, with first bolts fitted at both the top and bottom of the horizontal sleeve, and the two first bolts penetrating the two side walls of the horizontal sleeve respectively, with abutment joints provided at the inner ends of the two first bolts.

[0011] Furthermore, the linear reciprocating mechanism includes linear modules embedded on both sides of the frame and moving synchronously, and the sliding blocks of the two linear modules are connected to the horizontal sleeve through the second connecting rod.

[0012] Furthermore, there are two grinding plates, and the two grinding plates are arc-shaped. The inner arc surfaces of the two grinding plates are arranged opposite each other, and each inner arc surface is provided with several grinding protrusions. The two ends of the outer arc surface of the grinding plates are provided with sliding rods, which slide through the grinding ring. The top and bottom of the grinding ring are fitted with second bolts, and the two second bolts pass through the two side walls of the grinding ring respectively. The inner ends of the two second bolts abut against the outer arc surfaces of the two grinding plates respectively.

[0013] Furthermore, several first connecting rods are provided with annular air blowing plates, which are coaxially arranged with the grinding ring. Annular air passages are provided inside the annular air blowing plates, which are connected to the blower. Several jet nozzles pointing towards the axis are provided on the circumferential direction of the inner sidewall of the annular air blowing plates.

[0014] Furthermore, the bottom of the frame is equipped with several casters.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This solution allows the end of the reinforcing bar to be fixed within the horizontal sleeve by adjusting the first bolt. By adjusting the second bolt, two grinding plates can be driven to clamp the reinforcing bar. The two grinding plates are rotated by a drive motor, and the reinforcing bar is moved in a linear reciprocating motion along its axis by a linear reciprocating mechanism. This causes the grinding teeth on the grinding plates to perform reciprocating spiral grinding on the reinforcing bar, thereby achieving comprehensive grinding of the reinforcing bar. This effectively avoids rust residue, improves the rust removal effect, and the grinding and rust removal process is convenient, time-saving, and labor-saving.

[0017] 2. This solution uses several air nozzles on the annular air blowing plate to blow away the rust residue on the outer wall of the steel bar after grinding, making it highly practical. Attached Figure Description

For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0022] like Figure 1 and Figure 2 As shown, the steel bar grinding and rust removal device of this scheme includes a frame 1. One end of the frame 1 is limited by a freely rotatable rotating ring 2. Specifically, one end of the rotating ring 2 is provided with a sliding ring 3. Both sides of the frame 1 are provided with sliding seats 4. The sliding seats 4 are provided with sliding grooves 5 that slide with the sliding ring 3. The cross-section of the sliding ring 3 is L-shaped, and the sliding groove 5 is an arc groove with an L-shaped cross-section. This arrangement not only limits the rotation of the rotating ring 2, but also does not affect the rotation of the rotating ring 2. The rotating ring 2 is connected to the drive motor 6 for transmission. Specifically, the outer side wall of the rotating ring 2 is provided with several gear teeth 7 in the circumferential direction, and the shaft of the drive motor 6 is provided with a drive gear 8 that meshes with the several gear teeth 7.

[0023] The rotating ring 2 is connected to the grinding ring 10 located in the middle through four first connecting rods 9. The grinding ring 10 is provided with two grinding plates 11 for clamping and grinding steel bars. The two grinding plates 11 are arc-shaped, and the inner arc surfaces of the two grinding plates 11 are arranged opposite each other. Each inner arc surface is provided with several grinding protrusions 12. Both ends of the outer arc surface of the grinding plate 11 are provided with sliding rods 13. The sliding rods 13 slide through the grinding ring 10. The top and bottom of the grinding ring 10 are fitted with second bolts 14. The two second bolts 14 pass through the two side walls of the grinding ring 10 respectively. The inner ends of the two second bolts 14 abut against the outer arc surfaces of the two grinding plates 11 respectively.

[0024] A fixing component is movably mounted on the frame 1, and the fixing component is mounted on the linear reciprocating mechanism and moves linearly reciprocally along the extension direction of the reinforcing bar; specifically, the fixing component includes a horizontal sleeve 15 coaxially mounted with the grinding ring 10, and the top and bottom of the horizontal sleeve 15 are fitted with first bolts 16, and the two first bolts 16 respectively penetrate the two side walls of the horizontal sleeve 15, and the inner ends of the two first bolts 16 are provided with abutment joints; the linear reciprocating mechanism includes linear modules embedded on both sides of the frame 1 and moving synchronously, and the sliding blocks of the two linear modules are connected to the horizontal sleeve 15 through the second connecting rod 17.

[0025] The working process of this plan will be explained in detail below:

[0026] This solution uses two first bolts 16 to fix the end of the reinforcing bar within the horizontal sleeve 15. By adjusting two second bolts 14, two grinding plates 11 can clamp the other end of the reinforcing bar. The two grinding plates 11 are driven to rotate by the drive motor 6, and the reinforcing bar is driven to move linearly along its axis by the linear reciprocating mechanism. This causes the grinding teeth 12 on the grinding plates 11 to perform reciprocating spiral grinding on the reinforcing bar, thereby achieving comprehensive grinding of the reinforcing bar. This effectively avoids rust residue, improves the rust removal effect, and the grinding and rust removal process is convenient, time-saving, and labor-saving.
