Description

Technical Field

[0001] The invention belongs to the technical field of pipeline maintenance, and in particular relates to a working platform for pipeline maintenance. Background Art

[0002] Pipeline repair refers to the use of various technologies to restore the normal use function of damaged or leaking pipelines. The repair includes two technologies: external anti-corrosion layer repair and internal repair. In the process of repairing the external anti-corrosion layer of the pipeline, a corresponding work platform is required to provide a maintenance platform for maintenance personnel, so that maintenance personnel can quickly repair the external anti-corrosion layer of the pipeline, ensure the normal operation of the pipeline, and extend the service life of the pipeline.

[0003] Existing work platforms for pipeline maintenance generally include a platform body, a scissor-type hydraulic lifting device and a horizontal moving device. The scissor-type hydraulic lifting device is installed on the horizontal moving device, and the platform body is installed on the scissor-type hydraulic lifting device. The scissor-type hydraulic lifting device can drive the platform body to move to the maintenance position of the pipeline, making it convenient for maintenance personnel to inspect it. The horizontal moving device can drive the platform body to move along the pipeline laying direction.

[0004] Since some pipelines are installed near water or cliffs, there is insufficient space below these locations to place existing horizontal moving devices or scissor-type hydraulic lifting devices, resulting in the inability of existing pipeline maintenance work platforms to reach the locations of pipelines that need to be inspected. Therefore, normal pipeline maintenance work cannot be carried out, which has certain limitations.

[0005] Therefore, in view of the above situation, there is an urgent need to develop a pipeline maintenance work platform to overcome the shortcomings in current practical applications. Summary of the invention

DETAILED DESCRIPTION

[0049] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0050] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0051] like Figures 1 to 7 As shown, a pipeline maintenance work platform provided as an embodiment of the present invention comprises two groups of platform bodies 1 arranged on both sides of a pipeline 3, fences 2 are installed on the two groups of platform bodies 1, lateral slide grooves 12 are opened on the end faces of the two groups of platform bodies 1 close to each other, bottom slide grooves 11 are opened on the bottoms of the two groups of platform bodies 1, and three mounting frames 4 are arranged between the two groups of platform bodies 1, the three mounting frames 4 are all located below the pipeline 3, the two ends of the two mounting frames 4 are respectively slidably installed in the lateral slide grooves 12 on the two groups of platform bodies 1, and the two ends of one mounting frame 4 are respectively fixedly connected to one end of the two groups of platform bodies 1, and also includes:

[0052] The assembly mechanism 5 comprises a first assembly component 51, a second assembly component 52 and a third assembly component 53, wherein the second assembly component 52 is located between the first assembly component 51 and the third assembly component 53, the first assembly component 51 is mounted on a mounting frame 4 fixedly connected to the platform body 1, the second assembly component 52 and the third assembly component 53 are respectively mounted on two mounting frames 4 slidably matched with the lateral slide groove 12, the first assembly component 51 and the third assembly component 53 are both frictionally connected to the outer wall of the pipe 3, and the second assembly component 52 is rollingly connected to the outer wall of the pipe 3;

[0053] A main control mechanism 6, one end of which is fixed between the two sets of platform bodies 1, and the other end of which passes through two mounting frames 4 and is screwed to a mounting frame 4 on the third assembly component 53;

[0054] The adjustment mechanism 7 includes a linkage component 71, an adjustment plate 72, an adjustment frame 73 and an adjustment component 74. One end of the linkage component 71 is connected to the second assembly component 52, and the other end of the linkage component 71 is connected to the adjustment plate 72. The adjustment plate 72 is vertically slidably installed on the adjustment frame 73. The adjustment frame 73 is slidably installed in the bottom slide groove 11, and one side of the adjustment frame 73 is fixedly connected to the mounting frame 4 on the second assembly component 52. One end of the adjustment component 74 is fixed on the adjustment plate 72, and the other end of the adjustment component 74 is installed on the main control mechanism 6.

[0055] In this embodiment, in the initial state, the mounting frame 4 on the third assembly component 53 is located at one end of the main control mechanism 6. When it is necessary to drive the two sets of platform bodies 1 to move along the laying direction of the pipeline 3, the third assembly component 53 clamps the outer wall of the pipeline 3 by telescoping, and the third assembly component 53 and the mounting frame 4 thereon are in a stationary state relative to the pipeline 3. The second assembly component 52 is rollingly connected to the outer wall of the pipeline 3 by telescoping, and the first assembly component 51 is released from the outer wall of the pipeline 3 by telescoping. The main control mechanism 6 can drive the platform body 1 to move along the laying direction of the pipeline 3 by being screwed with the mounting frame 4 on the third assembly component 53. The platform body 1 drives the first assembly component 51 and the second assembly component 52 to move along the laying direction of the pipeline 3. The second assembly component 52 rolls on the pipeline 3 while moving. In this way, the two mounting frames 4 can always be kept connected to the outer wall of the pipeline 3 during the movement of the platform body 1, thereby improving the connection stability between the platform body 1 and the pipeline 3, thereby improving the stability and safety of the platform body 1 during the movement.

[0056] When the second assembly component 52 moves to a position close to the third assembly component 53, the state of the second assembly component 52 remains unchanged, the first assembly component 51 resumes the clamping action on the outer wall of the pipe 3 by telescoping, and the third assembly component 53 releases its connection with the pipe 3 by telescoping, so that the third assembly component 53 is in a free state relative to the pipe 3. At the same time, the platform body 1 is in a stationary state relative to the pipe 3, so that the main control mechanism 6 can drive the mounting frame 4 on the third assembly component 53 to slide in the lateral slide groove 12. At this time, the mounting frames 4 on the first assembly component 51 and the second assembly component 52 are in contact with the outer wall of the pipe 3. The main body 1 is connected to the pipeline 3, so that whether the platform body 1 is moving or stationary, it can be ensured that there are two or more connection points between it and the pipeline 3, thereby ensuring its stability on the pipeline 3. The mounting frame 4 on the third assembly component 53 drives the third assembly component 53 to move in a direction away from the second assembly component 52, so that the third assembly component 53 moves to one end of the main control mechanism 6 again, and the cycle repeats, thereby driving the platform body 1 to continue to move along the laying direction of the pipeline 3, so that the staff on the platform body 1 can inspect the pipeline 3 along the laying direction of the pipeline 3, thereby improving the inspection efficiency and inspection quality of the pipeline 3;

[0057] When the second assembly component 52 moves to the position where the pipe 3 is connected, the first assembly component 51 and the third assembly component 53 are in a state of clamping the pipe 3 at the same time, so that the mounting frames 4 on the two can be connected to the pipe 3. The second assembly component 52 can not only release the connection between it and the pipe 3 by telescoping, but also drive the linkage component 71 to work. The linkage component 71 drives the adjustment plate 72 to move vertically on the adjustment frame 73. The adjustment plate 72 drives one end of the adjustment component 74 to move to match with the other end thereof. The adjustment component 74 can drive the adjustment plate 72 to move horizontally by cooperating with each other at both ends. The adjusting plate 72 drives the adjusting frame 73 to slide on the bottom slide groove 11, and the adjusting frame 73 drives the second assembly component 52 to move on the platform body 1 through the mounting frame 4, so that the second assembly component 52 can be moved from one pipeline 3 to another pipeline 3, ensuring that the second assembly component 52 can be effectively connected with the outer wall of the pipeline 3 in a rolling manner during the movement of the platform body 1, thereby ensuring the stability of the platform body 1 on the pipeline 3, so that the working platform has the ability to flexibly handle when encountering the connection between the pipeline 3, which can not only improve the safety of the platform body 1, but also improve the maintenance efficiency and quality of the pipeline 3.

[0058] like Figures 1 to 6As shown, as a preferred embodiment of the present invention, the main control mechanism 6 includes a motor A61, a motor frame 62, a screw 63 and a guide column 64. The motor A61 is fixed to one end of the platform body 1 close to the first assembly component 51 through the motor frame 62. A screw 63 is fixed to the output end of the motor A61. One end of the screw 63 passes through the mounting frame 4 on the first assembly component 51 and the second assembly component 52 in sequence and is screwed to the mounting frame 4 on the third assembly component 53. One end of the guide column 64 is fixed to the motor frame 62, and the other end of the guide column 64 slides with the mounting frames 4 on the first assembly component 51, the second assembly component 52 and the third assembly component 53 in sequence.

[0059] In this embodiment, the motor A61 drives the screw 63 to rotate. The screw 63 can drive the mounting frame 4 or the motor frame 62 on the third assembly component 53 to move by being screwed with the mounting frame 4 on the third assembly component 53. The mounting frame 4 on the third assembly component 53 can drive the third assembly component 53 to move on the platform body 1. The motor frame 62 can drive the platform body 1 to move. The platform body 1 can drive the first assembly component 51 and the second assembly component 52 to move, so that the platform body 1 can continuously move along the laying direction of the pipeline 3, thereby facilitating the staff to quickly inspect the pipeline 3 and improving the inspection quality and efficiency of the pipeline 3.

[0060] like Figures 1 to 6 As shown, as a preferred embodiment of the present invention, a blocking member 65 is fixed on the guide column 64, which intermittently interferes with the mounting frame 4 on the second assembly component 52. The blocking member 65 is located on one side of the second assembly component 52 and close to the first assembly component 51. The blocking member 65 preferably adopts an annular block structure. When the platform body 1 moves with the motor frame 62, the motor frame 62 also drives the guide column 64 thereon to move, and the guide column 64 drives the blocking member 65 to move, so that the platform body 1 can drive the first assembly component 51 to move, and the blocking member 65 can push the mounting frame 4 on the second assembly component 52, so that the second assembly component 52 can move with the platform body 1, ensuring that the center of gravity position of the platform body 1 will not change significantly, thereby improving the stability of the platform body 1, and when the second assembly component 52 does not encounter the connection of the pipeline 3, it can ensure that the distance between the first assembly component 51 and the second assembly component 52 remains unchanged, further improving the stability of the platform body 1.

[0061] like Figures 1 to 6As shown, as a preferred embodiment of the present invention, the first assembly component 51, the second assembly component 52 and the third assembly component 53 all include a hydraulic component 54, a U-shaped block 55, a connecting rod 56, an arc-shaped rotating frame 57, an arc-shaped clamping block 58 and a roller 59, the hydraulic component 54 is fixed on the mounting frame 4, and a U-shaped block 55 is fixed on the output end of the hydraulic component 54, one end of the U-shaped block 55 is rotatably mounted with two connecting rods 56, one end of the two connecting rods 56 is rotatably connected to one end of two arc-shaped rotating frames 57 rotatably mounted on both sides of the mounting frame 4, and the other ends of the two arc-shaped rotating frames 57 are respectively mounted with an arc-shaped clamping block 58 frictionally connected to the outer wall of the pipeline 3, the U-shaped block 55 on the second assembly component 52 is connected to the linkage component 71, and the inner side of the arc-shaped clamping block 58 on the second assembly component 52 is mounted with a roller 59 rollingly connected to the outer wall of the pipeline 3.

[0062] In this embodiment, the hydraulic component 54 can drive the U-shaped block 55 to move vertically by telescoping. The U-shaped block 55 drives two arc-shaped rotating frames 57 to rotate on the mounting frame 4 through two connecting rods 56. The two arc-shaped rotating frames 57 drive their respective arc-shaped clamping blocks 58 to rotate, so that the arc-shaped clamping blocks 58 can not only clamp the outer wall of the pipeline 3, but also release the connection between it and the pipeline 3. The U-shaped block 55 on the second assembly component 52 can drive the linkage component 71 connected thereto to move by moving. The arc-shaped clamping block 58 on the second assembly component 52 can drive the roller 59 thereon to rotate, so that the roller 59 can not only be rollingly connected to the outer wall of the pipeline 3, but also release the connection between it and the pipeline 3, ensuring that the platform body 1 can stably and continuously move along the laying direction of the pipeline 3, thereby improving the maintenance efficiency and maintenance quality of the pipeline 3.

[0063] In a preferred embodiment, the hydraulic component 54 preferably adopts a hydraulic system composed of a hydraulic cylinder and a hydraulic rod, and may also adopt an electrically controlled structure that meets the requirements.

[0064] like Figures 3 to 7 As shown, as a preferred embodiment of the present invention, the linkage assembly 71 includes a rack A711, a gear A712 and a rack B713, the rack A711 is fixed on the U-shaped block 55 of the second assembly assembly 52, the gear A712 is rotatably mounted on one side of the adjustment frame 73, the rack B713 is fixed on the adjustment plate 72, and the rack A711 and the rack B713 are symmetrically arranged on both sides of the gear A712 and are respectively meshed with the two sides of the gear A712.

[0065] In this embodiment, the U-shaped block 55 on the second assembly component 52 drives the rack A711 to move downward, the rack A711 drives the rack B713 to move upward through the gear A712, and the rack B713 drives the adjustment plate 72 to move on the adjustment frame 73, so that the adjustment plate 72 can drive one end of the adjustment component 74 to move to a position matching its other end, thereby facilitating the second assembly component 52 to move independently on the platform body 1.

[0066] like Figures 3 to 7 As shown, as a preferred embodiment of the present invention, a groove is provided on one side of the guide column 64, and the groove is used for installing the other end of the adjustment component 74, and the groove is located between the second assembly component 52 and the third assembly component 53, so that it can be ensured that the second assembly component 52 can only move in the direction close to the third assembly component 53 during the single movement process, and will not interfere with the movement of the blocking member 65, so that the second assembly component 52 can fully and effectively pass through the connection of the pipeline 3, so that the platform body 1 can continue to move along the laying direction of the pipeline 3, thereby improving the maintenance efficiency of the pipeline 3.

[0067] like Figures 3 to 7 As shown, as a preferred embodiment of the present invention, the adjustment assembly 74 includes a motor B741, a main shaft 742, a gear B743 and a rack C744, the motor B741 is fixed on the adjustment plate 72, the main shaft 742 is fixed on the output end of the motor B741, the main shaft 742 is fixed on the gear B743, and the gear B743 is intermittently meshed with the rack C744 fixed on the groove.

[0068] In this embodiment, the adjustment plate 72 drives the motor B741, the main shaft 742 and the gear B743 to move upward synchronously, so that the gear B743 moves up to a position meshing with the rack C744. At this time, the motor B741 drives the main shaft 742 to rotate, and the main shaft 742 drives the gear B743 to rotate. Since the rack C744 is in a stationary state relative to the guide column 64, the gear B743 can drive the adjustment frame 73 to slide on the bottom slide groove 11 by cooperating with the rack C744. The adjustment frame 73 drives the second assembly component 52 to move on the platform body 1 through the mounting frame 4, so that the second assembly component 52 can be moved from one pipeline 3 to another pipeline 3, so that the working platform has the ability to flexibly handle when encountering the connection between the pipelines 3. This can not only improve the safety of the platform body 1, but also improve the maintenance efficiency and quality of the pipeline 3.

[0069] In a preferred embodiment, the meshing state of the gear B743 and the rack C744 is closely related to the connection relationship between the second assembly component 52 and the pipeline 3. When the second assembly component 52 is rollingly connected to the pipeline 3, the gear B743 is not meshed with the rack C744. This can avoid motion interference between the gear B743 and the rack C744. When the second assembly component 52 is connected to the pipeline 3, the gear B743 is meshed with the rack C744. This can effectively drive the second assembly component 52 to move alone on the platform body 1, so that it can smoothly pass through the connection of the pipeline 3, thereby ensuring that the platform body 1 can effectively and continuously move along the laying direction of the pipeline 3, thereby improving the maintenance efficiency and quality of the pipeline 3.

[0070] The working principle of the present invention is:

[0071] In the initial state, the mounting frame 4 on the third assembly component 53 is located at one end of the main control mechanism 6. When it is necessary to drive the two sets of platform bodies 1 to move along the laying direction of the pipeline 3, the third assembly component 53 clamps the outer wall of the pipeline 3 by telescoping. The third assembly component 53 and the mounting frame 4 thereon are in a stationary state relative to the pipeline 3. The second assembly component 52 is rollingly connected to the outer wall of the pipeline 3 by telescoping, and the first assembly component 51 is disconnected from the outer wall of the pipeline 3 by telescoping.

[0072] The motor A61 drives the screw 63 to rotate. The screw 63 can drive the platform body 1 to move along the laying direction of the pipeline 3 by being screwed with the mounting frame 4 on the third assembly component 53. The platform body 1 drives the first assembly component 51 and the second assembly component 52 to move along the laying direction of the pipeline. The second assembly component 52 rolls on the pipeline 3 while moving. In this way, the two mounting frames 4 can always be kept connected to the outer wall of the pipeline 3 during the movement of the platform body 1, thereby improving the connection stability between the platform body 1 and the pipeline 3.

[0073] When the second assembly component 52 moves to a position close to the third assembly component 53, the state of the second assembly component 52 remains unchanged, the first assembly component 51 resumes the clamping action on the outer wall of the pipe 3 by telescoping, and the third assembly component 53 releases the connection between it and the pipe 3 by telescoping, so that the third assembly component 53 is in a free state relative to the pipe 3. At the same time, the platform body 1 is in a stationary state relative to the pipe 3, and the motor A61 drives the screw 63 to rotate. The screw 63 can drive the motor frame 62 to move by being screwed with the mounting frame 4 on the third assembly component 53, and the motor frame 62 can drive the mounting frame 4 on the third assembly component 53 to slide in the lateral slide groove 12. At this time, the first assembly component 51 is in a free state relative to the pipe 3. The mounting brackets 4 on the assembly component 51 and the second assembly component 52 are connected to the outer wall of the pipeline 3, so that the platform body 1 can have two or more connection points with the pipeline 3 whether it is moving or stationary, thereby ensuring its stability on the pipeline 3. The mounting bracket 4 on the third assembly component 53 drives the third assembly component 53 to move in a direction away from the second assembly component 52, so that the third assembly component 53 moves to one end of the main control mechanism 6 again, and the cycle repeats, thereby driving the platform body 1 to continue to move along the laying direction of the pipeline 3, so that the staff on the platform body 1 can inspect the pipeline 3 along the laying direction of the pipeline 3, thereby improving the inspection efficiency and inspection quality of the pipeline 3;

[0074] When the second assembly component 52 moves to the position where the pipe 3 is connected, the first assembly component 51 and the third assembly component 53 are in a state of clamping the pipe 3 at the same time, so that the mounting frames 4 on the two can be connected to the pipe 3. The second assembly component 52 can not only release the connection between it and the pipe 3 by telescoping, but also drive the rack A711 to move downward through the U-shaped block 55 thereon, and the rack A711 drives the rack B713 to move upward through the gear A712, and the rack B713 drives the adjustment plate 72 to move on the adjustment frame 73, and the adjustment plate 72 drives the motor B741, the main shaft 742 and the gear B743 to move upward synchronously, so that the gear B743 moves up to the position meshing with the rack C744. At this time, the motor B741 drives the main shaft 742 to rotate, and the main shaft 742 drives the gear B743 to rotate , since the rack C744 is in a stationary state relative to the guide column 64, the gear B743 can drive the adjustment frame 73 to slide on the bottom slide groove 11 by cooperating with the rack C744, and the adjustment frame 73 drives the second assembly component 52 to move on the platform body 1 through the mounting frame 4, so that the second assembly component 52 can be moved from one pipe 3 to another pipe 3, so that the second assembly component 52 can smoothly pass through the connection of the pipe 3, ensuring that the second assembly component 52 can be effectively rolled and connected with the outer wall of the pipe 3 during the movement of the platform body 1, thereby ensuring the stability of the platform body 1 on the pipe 3, so that the working platform has the ability to flexibly handle when encountering the connection of the pipe 3, which can not only improve the safety of the platform body 1, but also improve the maintenance efficiency and quality of the pipe 3;

[0075] The above is the working principle of the pipeline maintenance work platform.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
