Description

Technical Field

[0001] This utility model relates to the field of rust removal and grinding technology, and in particular to a rust removal and grinding device for drill joints. Background Technology

[0002] When welding wear-resistant strips onto drill bit joints, to prevent impurities such as scale, rust, and dust from affecting the quality of the wear-resistant strip in the welded area, the drill bit joint at the welding location needs to be heated and cleaned. Before welding the wear-resistant strip, a handheld electrician's grinder is typically used for manual polishing. However, this manual polishing method has certain limitations. First, manual operation makes it difficult to ensure the uniformity and consistency of the polishing, potentially leading to insufficient cleanliness of the welded surface, thus affecting the welding quality and adhesion of the wear-resistant strip. Second, using a handheld electrician's grinder requires the operator to maintain a specific posture for extended periods of repetitive labor, which not only increases labor intensity but also easily leads to muscle strain. Furthermore, the grinding process generates a large amount of dust, which, if not properly protected, may harm the operator's health. Therefore, this manual polishing method presents high labor intensity and safety risks in practical applications. Existing technologies use grinding fixtures to remove rust and polish drill pipe joints. For example, patent application CN214922948U discloses a grinding device for a forged oil drill pipe joint. By starting a motor, the sleeve, connecting rod, and grinding disc rotate clockwise. Through the transmission component, the lead screw rotates clockwise, which in turn moves the drive disc horizontally towards the feeding platform. The fixed disc moves synchronously towards the feeding platform, and the connecting rod and grinding disc move synchronously towards the feeding platform. When the drive disc moves towards the feeding platform until the limit rod disengages from the movable groove, the drive disc abuts against the limit block and rotates in place. At the same time, the grinding disc abuts against the end of the joint and begins to grind the burrs at the end of the joint. This method can only grind the end of the drill pipe joint and cannot achieve the rotational grinding and rust removal of the drill pipe joint to be processed or the pushing of the drill pipe to be processed. Utility Model Content

[0006] Furthermore, the conveying roller bracket includes a bracket beam and several small rollers arranged side by side, the small rollers being disposed on the bracket beam.

[0007] Furthermore, the support wheel includes two rotating wheels and a fixed clamping plate. The two rotating wheels are fixed to the equipment bracket by the fixed clamping plate, and there is a gap between the two rotating wheels for placing the conveyor roller bracket.

[0008] Furthermore, the wire roller rotating mechanism includes a rotating wire brush, a counterweight bracket, a motor, and a transmission belt.

The lifting device 6 includes two synchronous lifting mechanisms 61, which are respectively connected to the mounting holes at both ends of the conveyor roller bracket 2.

[0028] like Figure 3 As shown, the support wheel 3 includes two rotating wheels 31 and a fixed clamping plate 32. The two rotating wheels 31 are fixed to the equipment bracket 1 by the fixed clamping plate 32. There is a gap between the two rotating wheels 31 for placing the conveyor roller bracket 2.

[0029] like Figure 4 As shown, the wire roller rotating mechanism 4 includes a rotating wire brush 41, a counterweight support 42, a motor 43, and a transmission belt 44.

The workpiece to be processed is moved laterally from the left side of the conveyor roller bracket 2 to the heater on the right side for heating.

The workpiece rotating roller mechanism 5 drives the workpiece to rotate through the active rotating roller 51 and the passive rotating roller 52. The wire roller rotating mechanism 4 is operated by the operating handle 46. While the workpiece is rotating, the rotating wire brush 41 removes rust and polishes the surface of the workpiece. After polishing, the lifting device 6 is lifted to raise the processed workpiece, and then the workpiece is removed via the conveyor roller bracket 2. This cycle is repeated.
