Description

Technical Field

[0001] The present application relates to the technical field of pressure pipeline detection, and in particular to a portable self-balancing pressure pipeline detection vehicle. Background Art

[0002] Pressure piping system is an important field in industrial pressure piping system, which is mainly used for various fluid transportation and transmission tasks. Pressure piping plays a vital role in many industries such as petrochemical, energy and electricity.

[0003] At present, traditional pressure pipeline inspection equipment is large in size and heavy in weight, which is not convenient to operate in a small space. Especially when inspecting the inside of a long-distance pressure pipeline, the convenience of transportation and operation of the equipment is crucial. Since the inspection equipment needs to conduct a full-scale inspection of the inside of the pressure pipeline, the inspection equipment will need to be able to approach multiple positions on the inner wall of the pressure pipeline. However, when such equipment passes through the bend of the pressure pipeline, the inspection equipment is prone to interfere with the pressure pipeline. Therefore, it can only be completely dismantled and reassembled after passing through. This is time-consuming and labor-intensive, which greatly reduces the inspection efficiency of the pressure pipeline. In addition, the inspection equipment also needs to adapt to the complex and changeable pressure pipeline environment. For example, when inspecting the bend of the pressure pipeline, the inspection equipment that is vertical when horizontal is difficult to maintain a vertical state here, and the tilted inspection equipment will greatly increase the risk factor during inspection, thereby greatly reducing the safety of pressure pipeline inspection. Summary of the invention

[0004] In order to improve the efficiency and safety when inspecting pressure pipelines, the present application provides a portable self-balancing pressure pipeline inspection vehicle.

[0005] The present application provides a portable self-balancing pressure pipeline inspection vehicle, which adopts the following technical solutions: A portable self-balancing pressure pipeline inspection vehicle comprises a detection frame moving in the pressure pipeline, a driving mechanism for driving the detection frame to move, and a detection device arranged on the detection frame, wherein the detection device comprises: The rotating platform is rotatably mounted on the detection frame via a rotating shaft; A rotating mechanism, used for driving the rotating platform to rotate and locking the rotating platform; The working platform is arranged on the rotating platform and is in a vertical state when in use and is used for workers to stand and inspect the pressure pipeline. When the inspection frame moves, the working platform angle is adjusted by the rotating platform to facilitate passing through the pressure pipeline.

[0006] By adopting the above technical solution, the driving mechanism drives the detection frame to move, and the detection frame drives the working platform to move to the detection location and stop moving, while the staff stands on the working platform to detect the inner wall of the pressure pipe. When it is necessary to pass through a bend or a narrow part of the pressure pipe, the rotating mechanism drives the rotating platform and the working platform to rotate, so that the working platform is rotated to a suitable angle for easy passing. After moving to the detection location, the rotating mechanism starts to drive the working platform to a vertical state, so that the staff can perform inspections on the working platform.

[0007] The working platform is driven to rotate by the rotating mechanism so that the angle of the working platform can adapt to passing through the bend of the pressure pipeline. When the working platform is moved to the inspection site, the rotating mechanism drives the working platform to a vertical state so that it can adapt to the inspection of the staff, thereby reducing the probability of completely disassembling the working platform and then reassembling it. It also allows the working platform to be in a vertical state during inspections in different environments, thereby greatly improving the inspection efficiency and safety of the pressure pipeline.

[0008] At the same time, when the work platform moves, the workers continue to stand in one place, thereby reducing the torque on the rotating mechanism during the movement of the work platform. When the workers use the work platform for inspection, the work platform is in a vertical state, that is, the work platform will be concentrated on the rotating shaft and the rotating mechanism under the action of gravity. Although the workers will continue to move, the torque on the rotating shaft and the rotating mechanism is not large, which reduces the probability of damage to the rotating mechanism and reduces the force required to maintain the stability of the working platform. Therefore, the stability of the rotating mechanism driving the working platform to rotate is greatly improved, and the inspection efficiency and safety of the pressure pipeline are further improved.

[0009] Optionally, the working platform includes: A hanging basket is arranged on a rotating shaft and is in a vertical state when in use; The main frame is detachably mounted on the hanging basket and horizontally extends to the outside of the hanging basket; The auxiliary frame is rotatably arranged on the end of the main frame away from the hanging basket and its upper surface is flush with the upper surface of the main frame when it is rotated to a horizontal state; Support members are arranged on the hanging basket, and when the sub-frame is turned to a horizontal state, it presses against a plurality of support members for support; The support and storage assembly is used to connect with the main frame and the auxiliary frame to achieve support and can drive multiple auxiliary frames to rotate to a vertical state for storage.

[0010] By adopting the above technical solution, the main frame and the sub-frame cooperate to form a standing space for the staff during inspection, thereby increasing the area of ​​the standing space, making the standing space more convenient for the staff to inspect the pressure pipeline. When the work platform needs to be moved, the support and storage assembly starts to drive the sub-frame to a vertical state for storage. At the same time, the rotation angle of the working platform and the cooperation of the two can make it easier to pass through the bend of the pressure pipeline. When moving to the inspection site, the support and storage assembly drives the sub-frame to a horizontal state and presses against the support member for support, so that it can be inspected by the staff, and the sub-frame is supported and positioned by the support member and the support storage assembly, thereby improving the stability of the sub-frame.

[0011] At the same time, when the auxiliary frame is turned to a vertical state and still cannot pass through the bend of the pressure pipeline, the main frame can be disassembled to facilitate passing, thereby further improving the convenience of passing through the bend of the pressure pipeline and improving the detection efficiency and safety of the pressure pipeline.

[0012] Optionally, the support and storage assembly is provided in plurality and connected to a plurality of main frames, and the support and storage assembly includes: A support rod 1, the top end of which is arranged on the hanging basket and the bottom end of which is inclined downward and connected to the main frame body located outside the hanging basket; The second and third support rods have one end rotatably connected to the hanging basket and the auxiliary frame respectively, and the ends close to each other are rotatably connected through a rotating tube; A fixing rod is arranged on the hanging basket and the top end of the fixing rod extends upwardly to the rotating tube in an inclined manner, and a first supporting hole and a second supporting hole are arranged at intervals on the fixing rod; A plug-in connector is installed on the rotating tube. When the plug-in connector is installed in the first support hole, the sub-frame is positioned in a horizontal state. When the plug-in connector is installed in the second support hole, the sub-frame is positioned in a vertical state.

[0013] By adopting the above technical scheme, support rod one is used to support and position the main frame, support rod two and support rod three cooperate to support the sub-frame, and at the same time, the connector is plugged into the rotating tube and support hole one to position the sub-frame, so that the fixed rod can also support and position the sub-frame, thereby further improving the stability of the sub-frame; when the sub-frame needs to be stored, the connector is pulled to disengage from support hole one, and then support rod one and support rod two are pulled to drive the sub-frame to rotate, so that the sub-frame turns to a vertical state, and then the connector is plugged into support hole two for positioning, so that the sub-frame can be positioned in a vertical state, thereby further improving the convenience during operation, thereby improving the detection efficiency and safety of the pressure pipeline.

[0014] Optionally, the fixing rod is provided with snap-in holes located at support hole one and support hole two, and positioning nuts are snap-fitted onto the two snap-in holes. When the connector is plugged into support hole one or support hole two, it is threadedly connected to the positioning nuts for positioning.

[0015] By adopting the above technical solution, the probability of the connector being detached is reduced by threading the connector and the positioning nut, thereby further improving the positioning effect and the safety during pressure pipeline inspection.

[0016] Optionally, a plurality of the main frames and auxiliary frames are horizontally spaced apart, and an arc-shaped balance beam is provided between two adjacent main frames.

[0017] By adopting the above technical scheme, multiple main frames and auxiliary frames are arranged at intervals, so that the force acting on the hanging basket can be balanced. At the same time, two adjacent main frames are connected by a balance beam, so that when a single main frame is subjected to force, the force can be distributed to other main frames, thereby further improving the stability during detection. At the same time, when the main frame is disassembled, the balance beam can also be disassembled, thereby further reducing the space occupied, making it easier to pass through the pressure pipeline, and further improving the detection efficiency and safety of the pressure pipeline.

[0018] Optionally, a plurality of guardrails are installed at intervals on the top of the hanging basket, and when the plurality of guardrails are placed vertically upward, they are connected to each other to form a working space for protection; or, when the plurality of guardrails are placed vertically downward, they are used to lower the height of the working platform and facilitate the passage of the working platform through a pressure pipe.

[0019] By adopting the above technical solution, during inspection, multiple guardrails are turned upward to a vertical upward state, and then the multiple guardrails are connected to each other for positioning, so that the multiple guardrails cooperate to protect the staff; when the work platform needs to be moved, the multiple guardrails are disassembled, and then the multiple guardrails are turned to a vertical downward state, so that the guardrails extend downward to below the connection between the guardrail and the hanging basket, thereby lowering the height of the working platform, making it easier to pass through the pressure pipeline, thereby improving the inspection efficiency and safety of the pressure pipeline at the same time.

[0020] Optionally, the driving mechanism includes: A plurality of guide wheels are arranged in the pressure pipe at intervals along the axis of the pressure pipe; A winch is arranged in the pressure pipe; The steel wire rope is wound on the winch and connected to the detection frame after passing through a plurality of guide wheels and is used to drag and position the detection frame; A plurality of supporting wheel groups are rotatably arranged at the bottom of the detection frame and roll on the inner wall of the pressure pipe for supporting and positioning; The traction vehicle is arranged on the detection frame and is used for driving the detection frame to move.

[0021] By adopting the above technical solution, a winch is installed at the outlet of the pressure pipe, a steel wire rope is wound on the winch, the steel wire rope is connected to the detection frame, and a plurality of guide wheels are rotatably installed on the inner wall of the pressure pipe, so that the steel wire rope bypasses the plurality of guide wheels, and a plurality of supporting wheel groups on the detection frame roll on the inner wall of the pressure pipe, so that the winch winds up the steel wire rope to pull the detection frame and the working platform to move, and at the same time the traction vehicle cooperates to drive the detection frame to move, thereby driving the working platform to move.

[0022] Optionally, the rotating mechanism includes: A collecting plate is arranged on the rotating shaft; A plurality of rotating wheels rotatably arranged on the bottom of the working platform; A steel rope is wound on a collecting plate and connected to the working platform after both ends are passed around at least one rotating wheel; The rotating assembly is used to drive the collecting tray to rotate.

[0023] By adopting the above technical solution, the two ends of the steel rope are passed around the rotating wheel and fixedly connected to the bottom of the working platform, and the rotating component starts to drive the rotating shaft and the collecting plate to rotate. The rotation of the collecting plate causes one of the two sections of the steel rope connected to the working platform to be released for inspection while the other section is recovered and shortened, thereby driving the working platform to rotate. Therefore, the two sections of steel rope located outside the collecting plate can both generate force on the bottom of the working platform under the action of the guide wheel, thereby improving the stability of the working platform after adjustment. In addition, the rotation of the collecting plate drives the working platform to rotate, so that the adjustable angle range of the working platform is larger, and the adjusted angle of the working platform can be closer to the required angle, that is, it is easier to pass through the bend of the pressure pipeline, thereby improving the detection efficiency and safety of the pressure pipeline at the same time.

[0024] Optionally, the rotating assembly includes: A gear, arranged on the rotating shaft; A rack, slidably disposed on the detection frame and meshing with the gear; The pushing member is arranged on the detection frame and is used to drive the rack to move.

[0025] By adopting the above technical solution, the pushing member starts to drive the rack to move, the rack movement drives the gear and the shaft to rotate, the shaft rotation drives the collection plate to rotate, thereby adjusting the angle of the working platform. After the conditions are met, the pushing member is used to maintain the position of the rack, that is, to maintain the angle of the working platform, and never drives the collection plate to rotate.

[0026] Optionally, the rack is provided with two pressure-bearing components located on both sides of the working platform, and the pressure-bearing components include: A pressure-bearing rod, which is arranged on the rack and extends downward to a position close to the bottom of the working platform; A pressure block is slidably arranged on the bottom of the pressure rod in a direction approaching or moving away from the working platform; A spring, with two ends respectively connected to the pressure-bearing rod and the pressure-bearing block; The pressure wheel is arranged on one end of the pressure block close to the working platform. The two pressure wheels are pressed against the opposite side walls of the working platform for positioning under the action of springs.

[0027] By adopting the above technical scheme, the two pressure wheels are pressed against the opposite side walls of the working platform under the action of springs for positioning, the rack moves to drive the pressure rod to move, the pressure rod moves to drive the pressure block and the pressure wheel to move, and the working platform rotates at the same time, and the two pressure wheels continue to press against the working platform under the action of springs, so as to continue to support the working platform, thereby better supporting the working platform, dividing the force of the rotating shaft, reducing the torque of the working platform on the rotating shaft, improving the stability of the working platform during the angle adjustment process, and improving the detection efficiency and safety of the pressure pipeline.

[0028] In summary, the present application includes at least one of the following beneficial technical effects: 1. The working platform is driven to rotate by the rotating mechanism so that the angle of the working platform can adapt to the bend of the pressure pipeline. When the working platform is moved to the inspection site, the rotating mechanism drives the working platform to a vertical state, so that it can adapt to the inspection of the staff, thereby reducing the probability of reassembly after the work platform is completely disassembled, and it can also make the working platform in a vertical state during inspections in different environments, thereby greatly improving the inspection efficiency and safety of the pressure pipeline.

[0029] 2. When the work platform moves, the workers continue to stand in one place, thereby reducing the torque on the rotating mechanism during the movement of the work platform. When the workers use the work platform for inspection, the work platform is in a vertical state, that is, the work platform will be concentrated on the rotating shaft and the rotating mechanism under the action of gravity. Although the workers will continue to move, the torque on the rotating shaft and the rotating mechanism is not large, which reduces the probability of damage to the rotating mechanism and reduces the force required to maintain the stability of the working platform. Therefore, the stability of the rotating mechanism driving the working platform to rotate is greatly improved, and the inspection efficiency and safety of the pressure pipeline are further improved.

When the detection frame 11 moves, the angle of the working platform 4 is adjusted by the rotating platform 31 to facilitate passing through the pressure pipeline 1; at the same time, the rotating mechanism 6 and the working platform 4 are both spliced ​​by multiple rods and plate structures.

[0038] Reference Figure 2 and 3 The working platform 4 includes a hanging basket 41, a main frame 42 and a sub-frame 43, a support 44 and a support storage assembly 5. The hanging basket 41 is fixedly installed on the rotating platform 31. The top of the hanging basket 41 extends vertically upward to above the detection frame 11 and the bottom is set vertically downward. At the same time, the distance between the bottom of the hanging basket 41 and the rotating shaft 12 is greater than the distance between the top and the rotating shaft 12, so that the hanging basket 41 can automatically rotate to a vertical state under the action of gravity.

[0039] Reference Figure 2 and 4, the hanging basket 41 is vertically spaced with multiple layers of mobile space for workers to stand, and connecting ladders are installed between adjacent layers, so as to realize the movement of workers; a horizontal mounting plate 18 is fixedly installed on the top of the hanging basket 41, and four guardrails 14 are spaced on the upper surface of the mounting plate 18, and the four guardrails 14 are in a vertical state, and the bottom of the guardrail 14 is fixedly installed in a horizontal state and a connecting plate 15 rotatably connected to the upper surface of the mounting plate 18, the four guardrails 14 are rotated to vertically upward and two adjacent guardrails 14 are positioned by plugging in a U-shaped plug rod 16, so that the four guardrails 14 cooperate to form a mouth-shaped working space, which is convenient for workers to detect the inner wall of the pressure pipeline 1; or, after removing the plug rod 16, the four guardrails 14 are rotated so that the connecting plate 15 is against the upper surface of the mounting plate 18, and the guardrail 14 is rotated to the outside of the mounting plate 18 and extends vertically downward to the bottom of the mounting plate 18, thereby reducing the height of the working platform 4, so as to facilitate the working platform 4 to move through the bend of the pressure pipeline 1.

The balance beam is used to connect multiple main frames 42 into a whole, so that the force is more balanced.

[0041] The sub-frame 43 is rotatably mounted on one end of the main frame 42 away from the hanging basket 41, and the length of the sub-frame 43 is smaller than that of the main frame 42; the support member 44 is fixedly mounted on one end of the main frame 42 away from the hanging basket 41 and is located below the sub-frame 43. When the sub-frame 43 is in a horizontal state, it presses against the support member 44 for support and positioning. At this time, the upper surfaces of the sub-frame 43 and the main frame 42 are flush, which is convenient for staff to detect the pressure pipeline 1; or, the sub-frame 43 is rotated to a vertical state for storage, so as to facilitate the working platform 4 to pass through the bend of the pressure pipeline 1.

[0042] If the auxiliary frame 43 is rotated to a vertical state and still cannot pass through the bend of the pressure pipe 1, the main frame 42 and the auxiliary frame 43 can be removed according to the obstruction situation, so as to facilitate passing through the bend of the pressure pipe 1; the protective rods 13 for protection can be detachably installed on the upper surface of the main frame 42 and the upper surface of the auxiliary frame 43. When the auxiliary frame 43 is rotated, part of the protective rods 13 are first removed to avoid the position.

[0045] When the sub-frame 43 is in a horizontal state, the connector 55 is installed on the rotating tube 17 and is threadedly connected to the positioning nut 59 after passing through the support hole 1 56 for positioning; when the sub-frame 43 needs to be stored, the connector 55 and the positioning nut 59 are twisted and removed from the support hole 1 56, and the support rod 2 52 is rotated to pull the support rod 3 53 and the sub-frame 43 to rotate. The bottom end of the support rod 2 52, i.e., the rotating tube 17, is rotated downward to the support hole 2 57. At this time, the sub-frame 43 is rotated to a vertical state, and the connector 55 is threadedly connected to the positioning nut 59 through the support hole 2 57 for positioning, thereby realizing the positioning of the sub-frame 43 in two states, and the structure is simple and stable.

[0046] Reference Figure 2 , Figure 3The rotating mechanism 6 includes a collecting plate 61, a plurality of rotating wheels 62, a steel rope 63, and a rotating assembly 7. The collecting plate 61 is coaxially fixedly mounted on the rotating shaft 12. The number of rotating wheels 62 is at least two and is evenly divided into two groups. The rotating wheels 62 are rotatably mounted on the side wall of the hanging basket 41 near the bottom. The two groups of rotating wheels 62 are horizontally spaced and located below the rotating shaft 12; the steel rope 63 is wound on the collecting plate 61, and the two ends of the steel rope 63 extend from both sides of the axis of the collecting plate 61 to form two connecting sections. The two connecting sections go around the two groups of rotating wheels 62 downward and then pass upward between the two groups of guide wheels 21. Finally, the two ends of the steel rope 63 are fixedly connected to the hanging basket 41. The collection plate 61 rotates so that one connecting section is released and stretched while the other connecting section is wound and shortened, thereby being able to pull the hanging basket 41 to rotate an angle.

[0047] The rotating assembly 7 is used to drive the collection plate 61 to rotate. The rotating assembly 7 includes a gear 71, a rack 72 and a pusher 73. The gear 71 is key-connected to the rotating shaft 12. The rack 72 is horizontally slidably installed on the side wall of the detection frame 11. The pusher 73 is an oil cylinder or an electric push rod. The pusher 73 is fixedly installed on the side wall of the detection frame 11, and the piston rod of the pusher 73 is connected to the rack 72. The pusher 73 drives the rack 72 to move, and the rack 72 moves to drive the gear 71 and the rotating shaft 12 to rotate. The rotating shaft 12 rotates to drive the suspension basket 41 to rotate, thereby adjusting the angle of the working platform 4, so as to facilitate passing through the bend of the pressure pipeline 1.

[0048] Two pressure-bearing components 8 are provided on the lower surface of the rack 72 and are located on both sides of the hanging basket 41. The pressure-bearing components 8 include a pressure rod 81, a pressure block 82, a spring 83, and a pressure wheel 84. The pressure rod 81 is fixedly installed on the lower surface of the rack 72 and extends downward to near the bottom of the hanging basket 41, and the pressure rod 81 is located on the outside of the hanging basket 41; the pressure block 82 is slidably arranged at the bottom of the pressure rod 81 along the direction approaching or moving away from the hanging basket 41, the spring 83 is fixedly installed on the pressure block 82 and is fixedly connected to the pressure rod 81, and the pressure wheel 84 is rotatably installed on one end of the pressure block 82 close to the hanging basket 41, and the two pressure wheels 84 are positioned against the opposite side walls of the hanging basket 41 under the elastic force of the two springs 83.

[0049] The rack 72 drives the suspension basket 41 to rotate, and at the same time, the rack 72 moves to drive the two pressure rods 81 to move, and the pressure rods 81 move to drive the two pressure wheels 84 to move. Therefore, the two pressure wheels 84 are pressed against the suspension basket 41 under the action of the spring 83 for positioning, so that the torque exerted on the rotating shaft 12 can be divided, thereby improving the stability of the working platform 4 during the angle adjustment process.

[0050] The working principle of the embodiment of the present application is as follows: The winch 22 starts to drive the detection frame 11 and the working platform 4 to move, and then the staff conducts inspection inside the pressure pipe 1; when it is necessary to pass through a bend or a narrow part of the pressure pipe 1, the pushing member 73 starts to push the working platform 4 to rotate, so as to adjust the angle of the working platform 4, so as to facilitate passing through the bend or narrow part of the pressure pipe 1. After reaching the inspection point, the pushing member 73 drives the working platform 4 to rotate, so that the hanging basket 41 is in a vertical state, thereby greatly improving the inspection efficiency and safety of the pressure pipe 1.
