Description

Technical Field

[0001] This invention belongs to the field of pipeline maintenance technology, and in particular relates to a working platform for pipeline maintenance. Background Technology

[0002] Pipeline repair refers to the use of various techniques to restore damaged or leaking pipelines to their normal function. Repair includes both external corrosion protection layer repair and internal repair techniques. During the repair of the external corrosion protection layer, a suitable work platform is required to provide maintenance personnel with a convenient platform for rapid inspection and repair of the pipeline's external corrosion protection layer, ensuring the normal operation of the pipeline and extending its service life.

[0003] Existing pipeline maintenance work platforms 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 move the platform body to the pipeline maintenance position, making it convenient for maintenance personnel to carry out maintenance. The horizontal moving device can move the platform body along the pipeline laying direction.

[0004] Because some pipelines are located near water or cliffs, there is insufficient space below these locations to place existing horizontal moving devices or scissor-lift hydraulic devices. As a result, existing pipeline maintenance platforms cannot reach the pipelines that need maintenance, thus limiting their ability to perform normal pipeline maintenance work.

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

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a working platform for pipeline maintenance to solve the problems mentioned in the background.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A pipeline maintenance work platform includes two sets of platform bodies disposed on both sides of a pipeline. Each set of platform bodies is equipped with a railing. Lateral sliding grooves are formed on the end faces of the two sets of platform bodies that are close to each other. Bottom sliding grooves are formed on the bottom of each set of platform bodies. Three mounting brackets are disposed between the two sets of platform bodies, all located below the pipeline. The ends of two mounting brackets are slidably mounted within the lateral sliding grooves on the two sets of platform bodies. The ends of one mounting bracket are fixedly connected to one end of each of the two sets of platform bodies. The platform also includes:

[0009] An assembly mechanism is provided, comprising a first assembly component, a second assembly component, and a third assembly component. The second assembly component is located between the first assembly component and the third assembly component. The first assembly component is mounted on a mounting bracket fixedly connected to the platform body. The second assembly component and the third assembly component are respectively mounted on two mounting brackets that slide in cooperation with the lateral slide groove. The first assembly component and the third assembly component are both in frictional contact with the outer wall of the pipe, and the second assembly component is in rolling contact with the outer wall of the pipe.

[0010] The main control mechanism has one end fixed between the two platform bodies, and the other end of the main control mechanism passes through the two mounting brackets and is screwed to a mounting bracket on the third assembly component;

[0011] The adjustment mechanism includes a linkage component, an adjustment plate, an adjustment frame, and an adjustment assembly. One end of the linkage component is connected to a second assembly component, and the other end of the linkage component is connected to the adjustment plate. The adjustment plate is vertically slidably mounted on the adjustment frame, and the adjustment frame is slidably mounted in a bottom groove. One side of the adjustment frame is fixedly connected to a mounting bracket on the second assembly component. One end of the adjustment assembly is fixed to the adjustment plate, and the other end of the adjustment assembly is mounted on the main control mechanism.

[0012] Initially, the mounting bracket on the third assembly component is located at one end of the main control mechanism. When it is necessary to move the two platform bodies along the pipeline laying direction, the third assembly component clamps the outer wall of the pipeline by telescopic movement. The third assembly component and its mounting bracket are stationary relative to the pipeline. The second assembly component rolls with the outer wall of the pipeline by telescopic movement. The first assembly component disconnects from the outer wall of the pipeline by telescopic movement. The main control mechanism moves the platform body along the pipeline laying direction by screwing it to the mounting bracket on the third assembly component. The platform body moves the first and second assembly components along the pipeline laying direction. The second assembly component rolls on the outer wall of the pipeline during the movement.

[0013] When the second assembly component moves to a position close to the third assembly component, the state of the second assembly component remains unchanged. The first assembly component resumes its clamping action on the outer wall of the pipe by telescopic movement. The third assembly component releases its connection with the pipe by telescopic movement, so that the third assembly component is in a free state relative to the pipe. At the same time, the platform body is in a stationary state relative to the pipe. The main control mechanism drives the mounting bracket on the third assembly component to slide in the lateral slide groove. At this time, the mounting brackets on the first and second assembly components are connected to the outer wall of the pipe. The mounting bracket on the third assembly component drives the third assembly component to move away from the second assembly component. The third assembly component moves to one end of the main control mechanism again.

[0014] When the second assembly component moves to the pipe connection point, both the first and second assembly components are simultaneously clamping the pipe. The second assembly component releases its connection to the pipe by extending and retracting, and also drives the linkage component to work. The linkage component drives the adjustment plate to move vertically on the adjustment frame. The adjustment plate drives one end of the adjustment component to move to mate with its other end. The adjustment component drives the adjustment plate to move horizontally by the mutual mate of its two ends. The adjustment plate drives the adjustment frame to slide on the bottom slide groove. The adjustment frame drives the second assembly component to move independently on the platform body through the mounting frame. The second assembly component smoothly passes through the pipe connection point by moving independently on the platform body.

[0015] As a further technical solution of the present invention, the main control mechanism includes:

[0016] A motor frame fixed to one end of the platform body, the motor frame being close to the first assembly component;

[0017] Motor A is fixed on the motor frame;

[0018] A screw fixed to the output end of motor A, one end of which passes sequentially through mounting brackets on the first and second assembly components and is screwed to a mounting bracket on the third assembly component; and

[0019] A guide post is fixed on the motor frame, and one end of the guide post slides in engagement with the mounting brackets on the first assembly assembly, the second assembly assembly, and the third assembly assembly in sequence.

[0020] As a further technical solution of the present invention, a blocking element is fixed on the guide post, which intermittently abuts against the mounting bracket on the second assembly assembly. The blocking element is located on one side of the second assembly assembly and close to the first assembly assembly. The blocking element adopts a ring-shaped block structure.

[0021] As a further technical solution of the present invention, the first assembly component, the second assembly component, and the third assembly component each include:

[0022] Hydraulic components fixed to the mounting bracket;

[0023] A U-shaped block is fixed on the output end of the hydraulic component, and the U-shaped block on the second assembly is connected to the linkage assembly;

[0024] Rotate the two connecting rods mounted on one end of the U-shaped block;

[0025] Rotate the two arc-shaped rotating brackets on both sides of the mounting frame respectively, with one end of each arc-shaped rotating bracket rotatably connected to two connecting rods; and

[0026] An arc-shaped clamping block is installed on the other end of the arc-shaped rotating frame. The inner side of the arc-shaped clamping block on the second assembly assembly is equipped with a roller that is in rolling connection with the outer wall of the pipe. The arc-shaped clamping blocks on the first assembly assembly and the third assembly assembly are in frictional connection with the outer wall of the pipe.

[0027] As a further technical solution of the present invention, the linkage component includes:

[0028] Rack A is fixed to the U-shaped block of the second assembly component;

[0029] Rotate gear A, which is mounted on one side of the adjusting frame; and

[0030] A rack B is fixed on the adjusting plate. Racks A and B are symmetrically arranged on both sides of gear A and mesh with both sides of gear A respectively.

[0031] As a further technical solution of the present invention, a groove is provided on one side of the guide post, the groove is used for the other end of the adjustment component to be installed, and the groove is located between the second assembly component and the third assembly component.

[0032] As a further technical solution of the present invention, the adjustment component includes:

[0033] Motor B is fixed to the adjustment plate;

[0034] The main shaft is fixed to the output end of motor B;

[0035] Gear B fixed on the main shaft; and

[0036] A rack C is fixed in a groove, and the rack C intermittently meshes with a gear B.

[0037] Compared with the prior art, the beneficial effects of the present invention are:

[0038] The assembly mechanism, in coordination with the main control mechanism, can move the platform body along the pipeline laying direction, enabling the personnel on it to effectively and quickly inspect the pipeline. At the same time, during the movement of the platform body, it can always ensure that there are two or more connection points between it and the pipeline, thereby ensuring its stability on the pipeline, improving the connection stability between the platform body and the pipeline, and thus improving the stability and safety of the platform body during the movement process. It also improves the efficiency and quality of pipeline inspection.

[0039] The second assembly component in the assembly mechanism can move independently on the platform body through telescopic movement and coordination with the adjustment mechanism, allowing it to smoothly pass through pipe connections. This ensures that the entire assembly mechanism can smoothly pass through pipe connections, ensuring that the platform body can move effectively and continuously along the pipe laying direction, improving pipe maintenance efficiency and quality. It also ensures that the second assembly component can effectively roll and connect with the outer wall of the pipe during the movement of the platform body, thus ensuring the stability of the platform body on the pipe. This gives the work platform the ability to handle pipe connections flexibly, improving both the safety of the platform body and the efficiency and quality of pipe maintenance.

Detailed Implementation

[0049] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0050] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0051] like Figures 1 to 7 As shown, a pipeline maintenance work platform provided in one embodiment of the present invention includes two sets of platform bodies 1 disposed on both sides of a pipeline 3. Each set of platform bodies 1 is equipped with a railing 2. Lateral sliding grooves 12 are formed on the end faces of the two sets of platform bodies 1 that are close to each other. Bottom sliding grooves 11 are formed on the bottom of each set of platform bodies 1. Three mounting brackets 4 are disposed between the two sets of platform bodies 1. All three mounting brackets 4 are located below the pipeline 3. The two ends of two mounting brackets 4 are slidably installed in the lateral sliding grooves 12 on the two sets of platform bodies 1. The two ends of one mounting bracket 4 are fixedly connected to one end of each of the two sets of platform bodies 1. The platform also includes:

[0052] Assembly mechanism 5 includes a first assembly component 51, a second assembly component 52, and a third assembly component 53. 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 bracket 4 that is fixedly connected to the platform body 1. The second assembly component 52 and the third assembly component 53 are respectively mounted on two mounting brackets 4 that slide in cooperation with the lateral slide groove 12. The first assembly component 51 and the third assembly component 53 are both in frictional contact with the outer wall of the pipe 3, and the second assembly component 52 is in rolling contact with the outer wall of the pipe 3.

[0053] The main control mechanism 6 has one end fixed between the two platform bodies 1, and the other end of the main control mechanism 6 passes through the two mounting brackets 4 and is screwed to a mounting bracket 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 mounted on the adjustment frame 73, and the adjustment frame 73 is slidably mounted in the bottom slide groove 11. One side of the adjustment frame 73 is fixedly connected to the mounting bracket 4 on the second assembly component 52. One end of the adjustment component 74 is fixed to the adjustment plate 72, and the other end of the adjustment component 74 is mounted on the main control mechanism 6.

[0055] In this embodiment, initially, the mounting bracket 4 on the third assembly component 53 is located at one end of the main control mechanism 6. When it is necessary to move the two platform bodies 1 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 bracket 4 on it are stationary relative to the pipeline 3. The second assembly component 52 is rolled to the outer wall of the pipeline 3 by telescoping. The first assembly component 51 is disconnected from the outer wall of the pipeline 3 by telescoping. The main control mechanism 6 can move the platform body 1 along the laying direction of the pipeline 3 by screwing it to the mounting bracket 4 on the third assembly component 53. The platform body 1 moves the first assembly component 51 and the second assembly component 52 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 brackets 4 are always connected to the outer wall of the pipeline 3 during the movement of the platform body 1, which improves 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 its 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 bracket 4 on the third assembly component 53 to slide in the lateral slide groove 12. At this time, the mounting brackets 4 on the first assembly component 51 and the second assembly component 52 are in a free state relative to the outer wall of the pipe 3. The connection ensures that the platform body 1 has two or more connection points with the pipeline 3, whether it is moving or stationary, thus 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 away from the second assembly component 52, so that the third assembly component 53 moves back to one end of the main control mechanism 6, and repeats this process. This allows the platform body 1 to move continuously along the laying direction of the pipeline 3, so that the personnel on the platform body 1 can carry out maintenance on the pipeline 3 along the laying direction of the pipeline 3, thereby improving the maintenance efficiency and 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 simultaneously clamping the pipe 3, allowing the mounting brackets 4 on both to connect to the pipe 3. The second assembly component 52, through telescopic movement, can not only disconnect itself from the pipe 3 but also drive the linkage component 71. The linkage component 71 drives the adjusting plate 72 to move vertically on the adjusting bracket 73. The adjusting plate 72 drives one end of the adjusting component 74 to engage with its other end. The adjusting component 74, through the engagement of both ends, can drive the adjusting plate 72 to move horizontally. The adjustment plate 72 drives the adjustment frame 73 to slide on the bottom slide groove 11. 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 move from one pipe 3 to another. This ensures that the second assembly component 52 can effectively roll and connect 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. This allows the work platform to have the ability to handle the connection of the pipe 3 flexibly, which can not only improve the safety of the platform body 1, but also improve the maintenance efficiency and maintenance quality of the pipe 3.

[0058] like Figures 1 to 6As shown, in 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 post 64. The motor A61 is fixed to one end of the platform body 1 near the first assembly component 51 via the motor frame 62. The screw 63 is fixed to the output end of the motor A61. One end of the screw 63 passes through the mounting brackets 4 on the first assembly component 51 and the second assembly component 52 in sequence and is screwed to the mounting bracket 4 on the third assembly component 53. One end of the guide post 64 is fixed to the motor frame 62, and the other end of the guide post 64 slides in cooperation with the mounting brackets 4 on the first assembly component 51, the second assembly component 52, and the third assembly component 53 in sequence.

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

[0060] like Figures 1 to 6 As shown, in a preferred embodiment of the present invention, a blocking member 65 is fixed on the guide post 64, which intermittently abuts against the mounting bracket 4 on the second assembly assembly 52. ​​The blocking member 65 is located on one side of the second assembly assembly 52 and close to the first assembly assembly 51. The blocking member 65 preferably adopts a ring-shaped block structure. When the platform body 1 moves with the motor frame 62, the motor frame 62 also drives the guide post 64 on it to move. The guide post 64 drives the blocking member 65 to move, so that the platform body 1 can drive the first assembly assembly 51 to move. The blocking member 65 can push the mounting bracket 4 on the second assembly assembly 52, so that the second assembly assembly 52 can move with the platform body 1, ensuring that the center of gravity of the platform body 1 will not change significantly, improving the stability of the platform body 1. Furthermore, when the second assembly assembly 52 does not encounter the connection of the pipe 3, it can ensure that the distance between the first assembly assembly 51 and the second assembly assembly 52 remains unchanged, further improving the stability of the platform body 1.

[0061] like Figures 1 to 6As shown, in a preferred embodiment of the present invention, the first assembly assembly 51, the second assembly assembly 52, and the third assembly assembly 53 each 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. Two connecting rods 56 are rotatably mounted on one end of the U-shaped block 55. 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. An arc-shaped clamping block 58 that rubs against the outer wall of the pipe 3 is mounted on the other end of each of the two arc-shaped rotating frames 57. The U-shaped block 55 on the second assembly assembly 52 is connected to the linkage assembly 71, and a roller 59 that rolls against the outer wall of the pipe 3 is mounted on the inner side of the arc-shaped clamping block 58 on the second assembly assembly 52.

[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 the 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 pipe 3, but also release the connection between them and the pipe 3. The U-shaped block 55 on the second assembly component 52 can drive the linkage component 71 connected to it to move by moving. The arc-shaped clamping blocks 58 on the second assembly component 52 can drive the roller 59 on it to rotate, so that the roller 59 can not only roll and connect with the outer wall of the pipe 3, but also release the connection between it and the pipe 3. This ensures that the platform body 1 can move stably and continuously along the laying direction of the pipe 3, improving the maintenance efficiency and quality of the pipe 3.

[0063] In a preferred embodiment, the hydraulic component 54 is preferably a hydraulic system consisting of a hydraulic cylinder and a hydraulic rod, but an electrically controlled structure that meets the requirements may also be used.

[0064] like Figures 3 to 7 As shown, in a preferred embodiment of the present invention, the linkage component 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 component 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. The racks A711 and B713 are symmetrically arranged on both sides of the gear A712 and mesh with both sides of the gear A712 respectively.

[0065] In this embodiment, the U-shaped block 55 on the second assembly component 52 drives the rack A711 to move downward, and the rack A711 drives the rack B713 to move upward through the gear A712. 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 that matches 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, in a preferred embodiment of the present invention, a groove is provided on one side of the guide post 64. The groove is used for the installation of the other end of the adjustment component 74. The groove is located between the second assembly component 52 and the third assembly component 53. This ensures that the second assembly component 52 can only move towards the third assembly component 53 during its individual movement, and will not interfere with the movement of the blocking component 65. This allows the second assembly component 52 to pass through the connection of the pipe 3 fully and effectively, so that the platform body 1 can continuously move along the laying direction of the pipe 3, thereby improving the maintenance efficiency of the pipe 3.

[0067] like Figures 3 to 7 As shown, in 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, and the main shaft 742 is fixed on the output end of the motor B741. The gear B743 is fixed on the main shaft 742, and the gear B743 intermittently meshes with the rack C744 fixed on the groove.

[0068] In this embodiment, the adjusting plate 72 drives the motor B741, the main shaft 742, and the gear B743 to move upward synchronously, so that the gear B743 moves upward to the position where it meshes 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 stationary relative to the guide post 64, the gear B743 can drive the adjusting frame 73 to slide on the bottom slide groove 11 by cooperating with the rack C744. 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 move from one pipe 3 to another pipe 3, so that the working platform has the ability to handle the connection of the pipe 3 flexibly. This not only improves the safety of the platform body 1, but also improves the maintenance efficiency and maintenance quality of the pipe 3.

[0069] In a preferred embodiment, the meshing state of gear B743 and rack C744 is closely related to the connection relationship between the second assembly assembly 52 and the pipe 3. When the second assembly assembly 52 is in a rolling connection with the pipe 3, gear B743 does not mesh with rack C744, thus avoiding motion interference between gear B743 and rack C744. When the second assembly assembly 52 is in a connected relationship with the pipe 3, gear B743 meshes with rack C744, which can effectively drive the second assembly assembly 52 to move independently on the platform body 1, allowing it to pass smoothly through the connection of the pipe 3. This ensures that the platform body 1 can move effectively and continuously along the laying direction of the pipe 3, improving the maintenance efficiency and quality of the pipe 3.

[0070] The working principle of this invention is:

[0071] Initially, the mounting bracket 4 on the third assembly component 53 is located at one end of the main control mechanism 6. When it is necessary to move the two platform bodies 1 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 its mounting bracket 4 are stationary relative to the pipeline 3. The second assembly component 52 is in rolling connection with the outer wall of the pipeline 3 by telescoping. The first assembly component 51 is released from connection with the outer wall of the pipeline 3 by telescoping.

[0072] Motor A61 drives screw 63 to rotate. Screw 63 is screwed to mounting bracket 4 on third assembly component 53, which can drive platform body 1 to move along the laying direction of pipe 3. Platform body 1 drives first assembly component 51 and second assembly component 52 to move along the laying direction of pipe. Second assembly component 52 rolls on pipe 3 while moving. This ensures that the two mounting brackets 4 are always connected to the outer wall of pipe 3 during the movement of platform body 1, improving the connection stability between platform body 1 and pipe 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 its clamping action on the outer wall of the pipe 3 by telescoping. The third assembly component 53 releases its connection with the pipe 3 by telescoping, making the third assembly component 53 free relative to the pipe 3. At the same time, the platform body 1 is stationary relative to the pipe 3. The motor A61 drives the screw 63 to rotate. The screw 63, through its screw connection with the mounting bracket 4 on the third assembly component 53, can drive the motor frame 62 to move. The motor frame 62 can drive the mounting bracket 4 on the third assembly component 53 to slide within the lateral slide groove 12. At this time, the first assembly component 52... The mounting brackets 4 on the assembly components 51 and 52 are connected to the outer wall of the pipe 3, ensuring that the platform body 1 has two or more connection points with the pipe 3 whether it is moving or stationary, thus ensuring its stability on the pipe 3. The mounting brackets 4 on the third assembly component 53 drive the third assembly component 53 to move away from the second assembly component 52, so that the third assembly component 53 moves back to one end of the main control mechanism 6, and repeats this process, thereby driving the platform body 1 to move continuously along the laying direction of the pipe 3, so that the personnel on the platform body 1 can inspect the pipe 3 along the laying direction of the pipe 3, improving the inspection efficiency and quality of the pipe 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 simultaneously clamping the pipe 3, allowing the mounting brackets 4 on both to connect to the pipe 3. The second assembly component 52, through telescopic movement, can not only disconnect itself from the pipe 3, but also move the rack A711 downwards via its U-shaped block 55. The rack A711, through gear A712, moves the rack B713 upwards. The rack B713 moves the adjusting plate 72 on the adjusting bracket 73. The adjusting plate 72 moves the motor B741, the main shaft 742, and the gear B743 upwards synchronously, causing the gear B743 to move to a position where it meshes 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 stationary relative to the guide post 64, the gear B743, through its cooperation with the rack C744, can drive the adjustment frame 73 to slide on the bottom slide groove 11. The adjustment frame 73, through the mounting frame 4, drives the second assembly component 52 to move on the platform body 1, so that the second assembly component 52 can move from one pipe 3 to another pipe 3, thereby allowing the second assembly component 52 to pass smoothly through the connection of the pipe 3. This ensures that the second assembly component 52 can effectively roll and connect 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. This allows the work platform to have the ability to handle the connection of the pipe 3 flexibly, which not only improves the safety of the platform body 1, but also improves the maintenance efficiency and quality of the pipe 3.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
