Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline rust removal clamping, in particular to a locking clamp for pipeline rust removal. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for transporting gas, liquid or fluid with solid particles. Pipes are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations. When processing the pipeline, it is necessary to remove rust from it, and when removing rust from it, it needs to be fixed with a clamp.

[0003] After searching, the patent with application number 201921894476.9 discloses a rust removal device for pipeline corrosion protection. The patent has an external rust removal component and an internal rust removal component to achieve simultaneous rust removal on the inner and outer surfaces of the pipeline, thereby improving the rust removal efficiency of the pipeline. However, it uses an upper clamping half ring, a lower clamping half ring and a nut to fix the pipeline. This fixing method not only makes the rust removal of the pipeline clamping part inadequate, but also has poor stability when only one end of the pipeline is fixed during use. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a locking clamp for rust removal of pipelines. By arranging a bidirectional screw, the two movable plates can be driven to approach each other in cooperation with a servo motor, thereby driving the two clamping blocks to approach each other. Since the clamping blocks are conical structures that gradually decrease from the outside to the inside, they can be clamped to the inside of the pipeline. Not only is it suitable for pipelines of different diameters, but it also avoids the situation where rust is not removed properly at the clamping parts outside the pipeline, and the stability is relatively high.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A locking clamp for pipeline rust removal, comprising a base and a locking mechanism; a fixing frame is fixed on the base, the fixing frame is in a "U"-shaped structure, a locking mechanism is provided at the bottom of the horizontal end of the fixing frame, the locking mechanism comprises a bidirectional screw, a servo motor and a movable plate, the vertical end of the fixing frame is rotatably connected with a bidirectional screw, a servo motor connected to the bidirectional screw is installed on the right side of the fixing frame, the bidirectional threads at both ends of the bidirectional screw are screwed with movable plates, the top end of the movable plate is slidably connected to the bottom side of the horizontal end of the fixing frame, a reduction motor is installed on the outer side of the bottom end of the movable plate, and the reduction motor is installed on the outer side of the reduction motor. The output shafts of the speed reducers all pass through the inner side of the moving plate and are fixed with clamping blocks. The clamping blocks are of a tapered structure that gradually decreases from the outside to the inside. By setting a bidirectional screw and cooperating with the servo motor, the two moving plates can be driven close to each other, thereby driving the two clamping blocks close to each other. Since the clamping blocks are of a tapered structure that gradually decreases from the outside to the inside, they can be clamped to the inside of the pipe. This is not only suitable for pipes of different diameters, but also avoids the situation where rust is not removed in place at the clamping part outside the pipe. The stability is relatively high. The clamping blocks are controlled by the speed reducer motor, which is convenient for driving the pipe to be derusted to rotate and for adjusting the derusting position of the pipe.

[0007] Furthermore, the base is provided with an iron chip collection box located directly below the locking mechanism, and the bottom surface of the inner cavity of the iron chip collection box is provided with an electromagnet bar. By setting up the iron chip collection box and cooperating with the electromagnet bar, iron chips in the rust removal process can be collected and cleaned.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: by setting a bidirectional screw and cooperating with a servo motor, the two movable plates can be driven to approach each other, thereby driving the two clamping blocks to approach each other; since the clamping block is a conical structure that gradually decreases from the outside to the inside, it can engage with the inside of the pipe, which is not only suitable for pipes of different diameters, but also avoids the situation where rust is not removed in place at the clamping part outside the pipe. The stability is relatively high; the clamping block is controlled by a reduction motor, which is convenient for driving the pipe to be derusted to rotate and for adjusting the derusting position of the pipe; by setting an iron filings collection box and cooperating with an electromagnet bar, iron filings in the rust removal process can be collected and cleaned.

[0011] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0012] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention. Example

[0013] See attached Figure 1 As shown, a locking clamp for pipeline rust removal includes a base 1 and a locking mechanism 3; a fixing frame 2 is fixed on the base 1, and the fixing frame 2 is a "U"-shaped structure. A locking mechanism 3 is provided at the bottom of the horizontal end of the fixing frame 2. The locking mechanism 3 includes a bidirectional screw 31, a servo motor 32 and a moving plate 33. The vertical end of the fixing frame 2 is rotatably connected with the bidirectional screw 31. The right side of the fixing frame 2 is equipped with a servo motor 32 connected to the bidirectional screw 31. The bidirectional threads at both ends of the bidirectional screw 31 are both screwed with moving plates 33. The top end of the moving plate 33 is slidably connected to the bottom side of the horizontal end of the fixing frame 2. The outer side of the bottom end of the moving plate 33 is equipped with a reduction motor 4. The output shafts of the reduction motors 4 all pass through the inner side of the moving plates 33 and are fixed with clamping blocks 5. The clamping blocks 5 are tapered structures that gradually shrink from the outside to the inside. By setting a bidirectional screw 31 and cooperating with the servo motor 32, the two moving plates 33 can be driven to approach each other, thereby driving the two clamping blocks 5 to approach each other. Since the clamping blocks 5 are tapered structures that gradually shrink from the outside to the inside, they can be engaged with the inside of the pipe. This is not only suitable for pipes of different diameters, but also avoids the situation where rust is not removed from the clamping parts on the outside of the pipe. The stability is relatively high. The clamping blocks 5 are controlled by the reduction motor 4, which is convenient for driving the pipe to be derusted to rotate and for adjusting the derusting position of the pipe.

[0014] The base 1 is provided with an iron chip collecting box 6 located just below the locking mechanism 3, and an electromagnet bar 7 is provided on the bottom surface of the inner cavity of the iron chip collecting box 6. By setting up the iron chip collecting box 6 and cooperating with the electromagnet bar 7, iron chips in the rust removal process can be collected and cleaned.

[0015] Working principle: The pipe to be derusted is placed between the two clamping blocks 5. The servo motor 32 drives the two moving plates 33 to approach each other through the bidirectional screw 31, thereby driving the two clamping blocks 5 to approach each other, so as to clamp and fix the pipe to be derusted. Since the clamping block 5 is a conical structure that gradually decreases from the outside to the inside, it can be engaged with the inside of the pipe. It is not only suitable for pipes of different diameters, but also avoids the situation where rust is not removed in place at the clamping part outside the pipe. It has high stability. The clamping block 5 is controlled by the reduction motor 4, which is convenient for driving the pipe to be derusted to rotate and facilitating the adjustment of the rust removal position of the pipe. By setting an iron filings collection box 6 and cooperating with the electromagnet bar 7, iron filings in the rust removal process can be collected and cleaned.

[0016] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model; therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description. Therefore, it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model, and any figure marks in the claims should not be regarded as limiting the claims involved.

[0017] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
