Description

Technical Field

[0001] The present invention relates to the technical field of building engineering construction, and in particular to a variable-diameter pipe cleaning and dust removal system and a construction method thereof. Background Art

[0002] Existing pipe cleaning devices come in a variety of styles. Some utilize a fixed cylindrical structure, with a circular brush head rotated by a transmission mechanism to achieve effective cleaning. This type of device has significant drawbacks: it can only clean pipes of varying diameters by changing the diameter of the circular brush head. When the bristles are too long or insufficiently stiff, cleaning effectiveness is significantly reduced. When the bristles are too short, the cylindrical structure must be replaced, or an electric telescopic mechanism must be installed to electrically adjust the length of the brush head to accommodate cleaning of pipes of varying diameters. Some pipe cleaning devices utilize an electric rotary mechanism to rotate and telescopically adjust a linear actuator. This type of device has limitations. Compared to a fixed cylindrical structure, the bristles of the electric rotary mechanism have much less contact surface with the pipe, and the number of brush heads is reduced, resulting in slower cleaning speeds and reduced efficiency. Increasing the cleaning speed can leave debris behind, resulting in poor cleaning results. In particular, neither of these two structural types of pipe cleaning devices is suitable for cleaning pipes of varying diameters or curved pipes. Summary of the Invention

In addition, for the cleaning construction of the variable diameter pipe 1, the number of scissor blade groups 15 in the variable diameter adjustment component can be adjusted according to the size of the pipe 1. By increasing and decreasing the number of scissor blade groups 15, cleaning and dust removal work can be performed on pipes of different diameters.

[0036] like Figure 5 and Figure 6 As shown, the secondary steering rod 24 also includes a spring 245, a guide ball 246 and a connector 247.

[0038] like Figure 7 As shown, the tail steering knuckle 50 includes a convex steering tube 51 and a steering connecting tube 52, which are bolted together.

It also includes a dust screen 53, which is riveted to the convex steering tube 51 and the steering connecting tube 52, with appropriate margins on both sides to ensure free rotation of the steering device. The convex steering tube 51 and the steering connecting tube 52 are both made of iron, while the dust screen 53 is made of nylon.

[0039] like Figure 8 As shown, the connecting device 60 includes a bolted fixed plate 61 and a connecting member 62. The fixed plate 61 is bolted to the travel propulsion device.

The main steering rod 21 passes through the center of the shell 32 and is connected to the tail steering knuckle 50. The four connecting plates 35 are evenly distributed in the radial direction and welded to the outer wall of the shell 32. The connecting plates 35 are provided with internal threads. The four dust collection pipes 34 correspond to the installation positions of the four connecting plates 35.

When the cleaning device rotates around its axis to clean the duct, it ensures that the dust removal device 30, the connecting device 60, and the travel propulsion device do not rotate with it. The support frame 37 of this embodiment is welded from Φ12 steel bars.

[0041] The variable-diameter pipe cleaning and dust removal system of the present invention also includes a control system, which includes a camera 72, a bracket 71, and a remote control terminal. The bracket 71 is welded to the connecting device 60, and the camera 72 is riveted to the bracket 71. The remote control terminal is connected to the camera 72, the cleaning device, and the walking propulsion device by signal. Construction personnel can more intuitively observe the cleaning effect through the camera 72 and remotely control the extension and stop of the lever-type telescopic arm. When the pipe 1 changes diameter, the cleaning device can achieve visual diameter change, so that the brush barrel 17 makes indiscriminate contact with the inner wall of the pipe 1, avoiding limited working space, reducing the labor intensity of construction personnel, and ensuring construction safety.

[0042] Combine Figures 1 to 11 The following steps describe the use of the variable diameter pipe cleaning and dust removal system of the present invention:

[0043] S1: Assemble the pipeline cleaning and dust removal system and place it in the pipeline 1. After the welding work of the pipeline 1 is completed and before the cleaning operation of the pipeline 1 is carried out, the rod-type telescopic arm of the cleaning device is controlled to extend and retract to drive the variable diameter adjustment component to expand or contract radially, so that the brush cylinder 17 contacts the inner wall of the variable diameter pipeline 1. The travel propulsion device drives the cleaning device to rotate to clean the pipeline 1, and pushes the cleaning device, the steering device and the dust removal device 30 to move along the axis of the pipeline 1 to perform the cleaning operation;

[0044] S2: When encountering a turn or a curved pipeline 1, the cleaning device turns along with the steering device, and the dust removal device 30 sucks out the dust generated after cleaning.

[0045] The method for using the variable-diameter pipeline cleaning and dust removal system of the present invention is as follows: first, the rod-type telescopic arm of the cleaning device is controlled to extend and retract to drive the variable-diameter adjustment component to expand or contract radially, so that the brush cylinder 17 contacts the inner wall of the variable-diameter pipeline 1, and the walking propulsion device drives the cleaning device to rotate to clean the pipeline 1, and pushes the cleaning device, the steering device and the dust removal device 30 to move along the axis of the pipeline 1 to perform cleaning operations; when encountering a turn in the straight pipeline 1 or cleaning in the curved pipeline 1, the linkage effect of the triple steering knuckle 211 of the main steering rod 21 and the secondary steering rod 24 and the tail steering knuckle 50 is utilized to make the cleaning device turn with the steering device, thereby achieving the cleaning effect of the straight pipe turn and the curved pipeline; the walking propulsion device pushes the cleaning device, the steering device and the dust removal device 30 to move along the axis of the pipeline 1 to perform cleaning operations, making subsequent cleaning work more convenient and simple, and indirectly reducing the labor in the cleaning process; the method for using the pipeline 1 cleaning and dust removal system can flexibly adjust the diameter or turn according to the on-site pipeline 1 situation, improve the cleaning efficiency of the pipeline 1, and be safe and reliable to use.

[0046] Step S1 further includes: a remote control terminal of the control system is connected to the camera device 72 and the cleaning device by signal connection. When the pipe 1 needs to be reduced in diameter, the camera device 72 is used to clearly observe the operation of the cleaning device in real time and transmit the data to the remote control terminal. The remote control terminal sends a signal to control the telescopic arm of the cleaning device to extend and retract, driving the diameter adjustment component to reduce the diameter, so that the brush cylinder 17 contacts the inner wall of the reduced diameter pipe 1 uniformly, realizing visual operation. After the pipe 1 is cleaned, the remote control terminal can assist in checking the cleanliness of the pipe 1 throughout the process. If the contamination is serious, the pipe 1 can be cleaned again. In this embodiment, the remote control terminal can be a mobile phone, tablet computer, PC, etc.
