Description

Technical Field

[0001] This utility model relates to the field of rust removal equipment technology, and in particular to a rust removal device for the outer wall of ductile iron pipes. Background Technology

[0002] Handheld laser rust removers are commonly used for removing rust from the outer walls of ductile iron pipes. Their technology is based on a high-energy-density laser beam acting on the metal surface. Through photothermal effects, the rust layer undergoes instantaneous vaporization, burning, or photodecomposition, achieving non-contact rust removal. This technology avoids the risk of substrate wear caused by traditional mechanical rust removal and is particularly suitable for scenarios where the graphite structure on the surface of ductile iron pipes needs to be preserved.

[0003] However, the following drawbacks exist in rust removal operations on the outer walls of cylindrical ductile iron pipes: limited by the linear operation mode of handheld devices, the pipe must be continuously rotated manually to achieve circumferential coverage, which significantly reduces work efficiency. To address these drawbacks, we propose a rust removal device for the outer walls of ductile iron pipes. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a rust removal device for the outer wall of ductile iron pipes.

[0005] To address the problems existing in the prior art, this utility model adopts the following technical solution: a rust removal device for the outer wall of ductile iron pipes, comprising:

[0007] The equipment rack consists of a base, a support frame fixedly installed on the upper surface of the base, and a top plate fixedly installed on the upper surface of the support frame, and the number of equipment racks is two;

[0008] A ductile iron pipe lifting structure includes a lifting steel rope, a guide wheel rotatably mounted on the lower surface of a top plate, an installation plate fixedly mounted on one end of the lifting steel rope, a connecting plate fixedly mounted on the lower surface of the installation plate, a lifting roller rotatably mounted on the surface of the connecting plate, and a drive assembly set on the upper surface of the base for winding and unwinding the lifting steel rope.

[0009] A guide structure, which is disposed inside the equipment frame, is used to guide the mounting plate.

[0010] Preferably, the drive assembly includes a connecting frame fixedly mounted on the upper surface of the base, a take-up roller rotatably mounted on the inner wall of the connecting frame, and a first motor fixedly mounted on the upper surface of the base, wherein the shaft end of the first motor is fixedly connected to the shaft end of the take-up roller.

[0011] Preferably, the end of the lifting steel rope away from the mounting plate is wound around the surface of the take-up roller.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a rust removal device for the outer wall of ductile iron pipe, comprising: a handheld laser rust removal instrument body 10, an equipment frame, a ductile iron pipe lifting structure, and a guide structure.

[0028] The equipment rack consists of a base 20, a support frame 21 fixedly installed on the upper surface of the base 20, and a top plate 22 fixedly installed on the upper surface of the support frame 21. There are two equipment racks. The base 20 is a counterweight block. The bottom of the base 20 is equipped with casters with brake function, which are not shown in the figure.

[0029] The ductile iron pipe lifting structure includes a lifting steel rope 30, a guide wheel 31 rotatably mounted on the lower surface of the top plate 22, a mounting plate 32 fixedly mounted on one end of the lifting steel rope 30, a connecting plate 33 fixedly mounted on the lower surface of the mounting plate 32, a lifting roller 34 rotatably mounted on the surface of the connecting plate 33, and a drive assembly disposed on the upper surface of the base 20 for winding and unwinding the lifting steel rope 30. The guide wheel 31 can guide the lifting steel rope 30, and the surface of the lifting roller 34 is provided with a rubber coating layer to increase the coefficient of friction.

[0030] The drive assembly includes a connecting frame 40 fixedly mounted on the upper surface of the base 20, a take-up roller 41 rotatably mounted on the inner wall of the connecting frame 40, and a first motor 42 fixedly mounted on the upper surface of the base 20. The shaft end of the first motor 42 is fixedly connected to the shaft end of the take-up roller 41. The end of the lifting steel rope 30 away from the mounting plate 32 is wound around the surface of the take-up roller 41. The surface of the lifting steel rope 30 rolls in cooperation with the guide wheel 31. Driving the first motor 42 can drive the take-up roller 41 to rotate, thereby enabling the lifting steel rope 30 to be wound up and unwound.

[0031] The guide structure is located inside the equipment frame and is used to guide the mounting plate 32. The guide structure includes two guide rods 70 symmetrically fixedly installed on the upper surface of the base 20, and two guide holes symmetrically opened on the surface of the mounting plate 32. The upper end of the guide rod 70 is fixedly connected to the lower surface of the top plate 22, and the surface of the guide rod 70 slides in fit with the guide hole. By utilizing the fit between the guide rod 70 and the sliding hole, the movement trajectory of the mounting plate 32 can be guided. When the first motor 42 is driven to wind up the lifting steel rope 30, the lifting steel rope 30 can be used to drive the mounting plate 32 and the lifting roller 34 to rise. Conversely, when the first motor 42 is driven to extend the lifting steel rope 30, the lifting steel rope 30 can be used to drive the mounting plate 32 and the lifting roller 34 to descend.

[0032] A limiting ring 60 is fixedly installed on the surface of the lifting roller 34. A second motor 50 is fixedly installed on one end of the connecting plate 33, and the output shaft of the second motor 50 is fixedly connected to the shaft end of the lifting roller 34. The two equipment frames are placed on both sides of the ductile iron pipe, and the lifting roller 34 is inserted into both ends of the ductile iron pipe. The limiting ring 60 is close to the end face of the ductile iron pipe. After the drive assembly cooperates with the lifting roller 34 to lift the ductile iron pipe and suspend it in the air, the second motor 50 is used to drive the lifting roller 34 to rotate. The friction between the lifting roller 34 and the inner wall of the ductile iron pipe is generated, which can drive the ductile iron pipe to rotate. This design completely replaces the manual rotation operation. Only the handheld laser rust remover body 10 needs to be moved laterally to carry out the operation, which can improve the rust removal efficiency. The distance between the two equipment frames can be adjusted to adjust the distance between the two lifting rollers 34, so that ductile iron pipes of different lengths can be lifted.

[0033] Specifically, the working principle and operation method of this utility model are as follows:

[0034] Place the two equipment racks symmetrically on both sides of the ductile iron pipe and adjust the spacing to be slightly larger than the length of the ductile iron pipe.

[0035] The lifting rollers 34 are inserted into both ends of the ductile iron pipe, and the limiting retaining rings 60 are pressed tightly against the pipe opening to prevent axial displacement.

[0036] The first motor 42 drives the winding roller 41 to wind up the lifting steel rope 30, and pulls the mounting plate 32 vertically upward through the guide wheel 31, so that the ductile iron pipe is suspended in the air.

[0037] The second motor 50 starts, driving the lifting roller 34 to rotate, which in turn drives the ductile iron pipe to rotate through friction.

[0038] The handheld laser rust remover body 10 moves at a constant speed along the axial direction of the ductile iron pipe to remove rust.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
