Description

Technical Field

[0001] The invention relates to the field of grouting, in particular to a speed-adjustable and self-adaptive grouting pipeline reciprocating cleaning device. Background Art

[0002] At present, in grouting projects, cleaning the residue inside the pipe has always been a difficult problem to solve. Traditional cleaning methods usually rely on simple flushing tools or mechanical equipment, most of which are based on manual operation or semi-automatic devices. The shape and structure of traditional products are usually long-pole cleaning equipment with a single-direction nozzle or brush for cleaning the inner wall of the pipe. This type of equipment usually relies on external push-pull to move, or slowly advances in the pipe through a simple wheel device.

[0003] However, these existing technologies have some obvious defects. First, because the nozzle direction of traditional equipment is fixed and difficult to adjust, the cleaning range is limited and cannot fully cover all corners of the inner wall of the pipeline. Secondly, this type of equipment can usually only move in one direction. If reverse cleaning is required, the equipment must be completely removed and reinserted into the pipeline, which is time-consuming and laborious. In addition, the propulsion method of traditional equipment mostly relies on external force rather than automatic propulsion of the equipment itself, which makes it difficult to operate in a complex pipeline environment and has low cleaning efficiency.

[0004] These problems seriously affect the efficiency and effectiveness of pipeline cleaning, especially in the cleaning of residues after grouting construction. Traditional methods often cannot completely remove stubborn residues in the pipeline. In order to solve these problems, the applicant proposed an adjustable speed adaptive grouting pipeline reciprocating cleaning device, which aims to achieve more thorough and efficient cleaning of residues in the pipeline through automatic propulsion, adjustable spray angle and two-way cleaning function. The purpose of this invention is to improve cleaning efficiency, reduce the complexity of manual operation, and ensure that the cleanliness of the inner wall of the pipeline reaches a higher standard. Summary of the invention

[0005] The purpose of the present invention is to provide a speed-adjustable and self-adaptive grouting pipeline reciprocating cleaning device to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions: A speed-adjustable self-adaptive grouting pipeline reciprocating cleaning device comprises a housing assembly, wherein a positioning wheel assembly and a high-pressure jet speed regulating assembly are arranged in the housing assembly; The positioning wheel assembly includes a first motor, a center piece, and a plurality of first extension mechanisms. The first motor drives the middle piece to rotate. The plurality of first extension mechanisms are connected around the center piece. The first extension mechanisms are extended under the drive of the first motor and the center piece. The outer ends of the first extension mechanisms are in contact with the inner wall of the pipe through the positioning wheel. The high-pressure jet speed regulation assembly includes a second motor, a second extension mechanism and a plurality of jet mechanisms. The plurality of jet mechanisms are connected around the second extension mechanism and are rotatably connected to the shell assembly. The second motor drives the second extension mechanism to extend, and the second extension mechanism drives the jet mechanism to rotate, thereby adjusting the inclination of the jet mechanism. The jet mechanism includes a high-pressure water gun, which sprays high-pressure water toward the inner wall of the pipe.

[0007] Furthermore, at least two positioning wheel assemblies are coaxially arranged in the housing assembly.

[0008] Furthermore, the first extension mechanism includes a first connecting rod rotatably connected to the center piece and a mounting rod rotatably connected to the first connecting rod, the mounting rod is also radially slidably plugged into the side shell wall of the shell assembly, and the positioning wheel is arranged on the mounting rod and located outside the shell assembly.

[0009] Furthermore, the second extension mechanism includes a crank connected to the output end of the second motor, a second connecting rod rotatably connected to the crank, and a third connecting rod rotatably connected to the second connecting rod, wherein the third connecting rod is vertically arranged and connected to all the injection mechanisms.

[0010] Furthermore, the third connecting rod is rotatably connected to a plurality of sliding sleeves, and all the injection mechanisms are slidably plugged into the sliding sleeves.

[0011] Furthermore, the spray mechanism also includes a speed regulating shaft connected to the high-pressure water gun, the speed regulating shaft is connected to the second extension mechanism, the high-pressure water gun is rotatably arranged on the side wall of the shell assembly, and the nozzle of the high-pressure water gun faces the outside of the shell assembly.

[0012] Furthermore, a window for accommodating the injection mechanism is provided on the side wall of the shell assembly.

[0013] Furthermore, a water tank is also provided on the shell assembly, and the injection assembly is connected to the water tank via a hose.

[0014] Furthermore, the high-pressure water gun has a reversing nozzle that can automatically change its angle, and the reversing nozzle drives the cleaning device to rotate by spraying cleaning liquid to the left or right toward the inner wall of the pipeline.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention can be automatically propelled and provides forward momentum through the backward spray of high-pressure water flow, avoiding the limitation of traditional equipment relying on external thrust, and greatly improving the convenience and efficiency of cleaning operations.

[0016] 2. The positioning wheel assembly can be adjusted according to the pipe diameter to ensure that the device always maintains a stable position in the pipe and will not overturn or shift due to changes in pipe diameter. This enables the device to adapt to pipe environments of different sizes and enhances its applicability.

[0017] 3. The spray angle of the high-pressure water gun of the present invention is adjustable. The user can adjust the spray angle as needed, thereby changing the moving speed of the grouting pipe cleaning device. This feature allows the device to flexibly adjust the cleaning intensity and speed when dealing with residues of different degrees, achieving a more precise cleaning effect.

[0018] 4. The reversing nozzle of the high-pressure water gun can rotate, allowing the user to change the spray direction and realize the two-way movement of the device. This means that the device can be cleaned back and forth without changing or repeatedly inserting the pipe, which greatly simplifies the operation process and saves time and manpower.

[0019] 5. In addition to being able to move along the pipeline, the entire device can also rely on the inclination of the nozzle to perform a process of moving and rotating, thereby achieving all-round cleaning of the inner wall of the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

When the device rotates, the water inlet pipe 4 will not be entangled due to being driven to rotate. The housing assembly 1 has a channel connecting the water inlet pipe 4 and the water tank 103. The jet assembly is connected to the water tank 103 through a hose.

[0031] Continue reading Figure 5In one embodiment of the present invention, the first extension mechanism includes a first connecting rod 202 rotatably connected to the center piece 201 and a mounting rod 203 rotatably connected to the first connecting rod 202, the mounting rod 203 is also radially slidably plugged into the side shell wall of the shell assembly 1, and the positioning wheel 204 is arranged on the mounting rod 203 and is located outside the shell assembly 1.

[0032] The first motor 200 is fixedly installed in the first installation cavity 101, and its output shaft is vertically arranged. The center piece 201 is a plum blossom wheel structure. The rotation center line of the center piece 201 and the first connecting rod 202 is vertically arranged. The rotation axis center line of the first connecting rod 202 and the installation rod 203 is vertically arranged. The first extension mechanism extends in the horizontal direction. The positioning wheel 204 is a universal ball wheel.

[0033] The positioning wheel assembly 2 moves linearly so that the positioning wheel can be in close contact with the inner wall of the pipe 5, so that the entire device can move axially in the pipe 4 without tilting or overturning.

[0034] Continue reading Figure 6 In one embodiment of the present invention, the second extension mechanism includes a crank 302 connected to the output end of the second motor 300, a second connecting rod 303 rotatably connected to the crank 302, and a third connecting rod 304 rotatably connected to the second connecting rod 303, and the third connecting rod 304 is vertically arranged and connected to all the ejection mechanisms. The second motor 300 is fixedly installed in the second installation cavity 102, the crank 302 rotates on a vertical plane, the first rotation center line of the crank 302 and the second connecting rod 303 is horizontally arranged, and the second rotation center line of the second connecting rod 303 and the third connecting rod 304 is parallel to the first rotation center line.

[0035] Further reading Figure 6 In one embodiment of the present invention, the third connecting rod 304 is rotatably connected to a plurality of sliding sleeves 305, and all the injection mechanisms are slidably mated with the sliding sleeves 305. The third rotation centerline of the third connecting rod 304 and the sliding sleeve 305 is parallel to the first rotation centerline.

[0036] Further reading Figure 6 In one embodiment of the present invention, the spray mechanism further includes a speed regulating shaft 306 connected to the high-pressure water gun 301, the speed regulating shaft 306 is slidably plugged and connected to the sliding sleeve 305 of the second extension mechanism, the high-pressure water gun 301 is rotatably arranged on the side wall of the housing assembly 1, and the nozzle of the high-pressure water gun 301 faces the outside of the housing assembly 1. A window 100 for accommodating the spray mechanism is provided on the side wall of the housing assembly 1.

[0037] In the high-pressure jet speed regulation assembly 3, the second motor 300 drives the crank 302 to rotate, and the crank 302 drives the second connecting rod 303 to rotate. The end of the second connecting rod 303 is connected to the third connecting rod 304. The bottom end of the third connecting rod 304 is connected to the sliding sleeve 305 by a hinge. The two sliding sleeves 305 can rotate at the bottom end of the third connecting rod 304. The speed regulation shaft 304 is inserted on the sliding sleeve 305. The third connecting rod 304 can only move vertically under the restraint of the two jet mechanisms, so that when the entire high-pressure jet speed regulation assembly 3 moves, the rotation center of the high-pressure water gun 301 can remain unchanged.

[0038] The present invention implements the reversing and speed change as follows: the second motor 300 drives the high-pressure water gun 301 to rotate through the crank 302 and other structures. When the reversing nozzle 307 of the high-pressure water gun 301 faces upward, the present invention moves downward, and when the reversing nozzle 307 of the high-pressure water gun 301 faces downward, the present invention moves upward. The inclination angle of the high-pressure water gun 301 is adjusted by the second motor 300 to achieve speed control. If you want to speed up the cleaning speed, increase the inclination angle of the high-pressure water gun 301. On the contrary, if you want to deeply clean the pipeline, reduce the inclination angle of the high-pressure water gun 301.

[0039] Rotation realization method of the present invention: the reversing nozzle 307 of the high-pressure water gun 301 of the present invention is equipped with a reversing motor, and the reversing motor controls the reversing nozzle 307 to rotate in the horizontal direction, so that the reversing nozzle 307 sprays the cleaning liquid to the left or right toward the inner wall of the pipe 5, thereby driving the device to rotate and realize all-round cleaning of the inner wall of the pipe 5. Among them, the rotation of the reversing nozzle 307 is a well-known technology, which can be realized by the nozzle fine-tuning mechanism 28 disclosed in patent CN113187085B, and can also be realized by the driving mechanism in patent CN116999745A.

[0040] The working process of the present invention: first, the speed needs to be set. If you want to speed up the cleaning speed, the device will increase the tilt angle of the nozzle. If you want to deeply clean the pipeline, the device will reduce its tilt angle, thereby increasing the impact force of the high-speed water flow on the pipeline, reducing the axial force and thus reducing the speed. After the setting is completed, water enters the water tank 103 from the water inlet pipe 4, and the water in the water tank 103 reaches the high-pressure water gun 301 through the hose and then sprays to clean the pipeline 5. The whole device starts to move and rotate. After reaching the top of the pipeline 5, it needs to be cleaned again and the water inlet pipe 4 is recovered. At this time, the operator performs the reversing setting and sets the speed. The high-pressure jet speed regulating component realizes the reversal by changing the nozzle direction of the high-pressure water gun 301. Then the high-pressure water gun 301 works again and cleans the pipeline again. After reaching the starting point, the device is recovered. If it needs to be cleaned again, repeat the above process.

[0041] It should be noted that the above technical term "horizontal" refers to a direction perpendicular to the axis of the pipeline 5, and does not necessarily limit the mechanism to being completely horizontal relative to the ground.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
