Specific embodiments

[0029] Embodiment 1

[0030] As Figures 1-9 shown, a pipeline maintenance construction device proposed in this embodiment includes a frame 1, an elastic pushing mechanism, two transmission belts 2, two groups of limit releasing mechanisms, and a plurality of lifting ring mechanisms.

[0031] A plurality of self-locking universal wheels 9 are installed at the bottom end of the frame 1, so as to facilitate the movement of the frame 1. A power mechanism for driving two transmission belts 2 to move synchronously is installed on the frame 1. The power mechanism includes a servo motor 3, a speed reducer 4, two transmission shafts 8 and four groups of transmission components. The two transmission shafts 8 are respectively rotatably installed at the upper and lower ends of the frame 1. The servo motor 3 and the speed reducer 4 are both installed on the frame 1. The output shaft of the servo motor 3 is connected to the input shaft of the speed reducer 4, and the output shaft of the speed reducer 4 is connected to the transmission shaft 8. The transmission component includes a toothed belt 7 and two toothed belt pulleys 6. The two toothed belt pulleys 6 are respectively installed on the transmission shafts 8 on both sides, and the two toothed belt pulleys 6 are connected by a toothed belt 7 for transmission connection. The four groups of transmission components are respectively arranged in pairs in the transmission belts 2 on both sides. The transmission belts 2 are fixedly sleeved on the outer circumferences of the two toothed belts 7 at the corresponding positions. The servo motor 3 is started to drive the speed reducer 4 to rotate. The speed reducer 4 rotates to drive the transmission shaft 8 to rotate, and then drives a plurality of toothed belt pulleys 6 to rotate. The toothed belt pulleys 6 drive the transmission belts 2 to rotate.

[0032] A plurality of lifting ring mechanisms are respectively installed on the transmission belts 2 on both sides. The plurality of lifting ring mechanisms on the transmission belts 2 on both sides are arranged in one-to-one correspondence. A number of balls 13 are installed on the inner wall of the lifting ring mechanism. By installing the balls 13, the pipeline can be easily rotated, so as to facilitate the detection of the pipeline. The lifting ring mechanism includes a semi-circular ring a51 and a semi-circular ring b52. A sliding connection block 15 is fixed between the semi-circular ring a51 and the transmission belt 2. The semi-circular ring a51 is rotatably connected to the semi-circular ring b52. A fixing mechanism is connected between the semi-circular ring a51 and the semi-circular ring b52. The fixing mechanism includes a sliding plate 19, a wedge block a20 and an elastic component a. A groove 511 is opened at the end of the semi-circular ring a51. The elastic component a includes a guide rod b21 and a spring b22. The guide rod b21 is arranged inside the groove 511. The sliding plate 19 is slidably arranged on the guide rod b21. The spring b22 is sleeved on the guide rod b21. The wedge block a20 is connected to the outer end of the sliding plate 19. A limiting groove 521 for the wedge block a20 to be inserted into is opened at the movable end of the semi-circular ring b52. The cross-section of the limiting groove 521 is an "L"-shaped structure.

[0033] A wedge block b23 is arranged inside the limiting groove 521. A push rod 24 is connected to the wedge block b23. The push rod 24 movably penetrates through the end of the semi-circular ring b52 and is connected to a connecting rod 25. Two groups of unlocking mechanisms are respectively used to automatically unlock the fixed connection state of the semi-circular rings b52 on both sides. The unlocking mechanism includes a guide plate 26. The guide plate 26 is vertically connected to the side of the frame 1. The bottom of the guide plate 26 has a bent structure.

[0034] The elastic pushing mechanism is installed at the bottom of the frame 1 to fix the semicircular ring b52 with the semicircular ring a51 again. The elastic pushing mechanism includes a vertical plate 17 and multiple groups of elastic connection components b. The vertical plate 17 is connected to the frame 1 through multiple groups of elastic components b; the elastic component b includes a guide rod a181, a spring a182 and a limit block 183. The bottom of the frame 1 is connected to the mounting frame 16, the guide rod a181 is connected to the mounting frame 16, the vertical plate 17 is slidably set on the guide rod a181, and the spring a182 It is sleeved on the guide rod a181, and the limit block 183 is set at the end of the guide rod a181. When the disconnected semi-circular ring b52 contacts the upper end of the vertical plate 17, the semi-circular ring b52 is forced to flip automatically. At the same time, as the lifting ring mechanism moves downward, the vertical plate 17 moves to the other side to ensure that the vertical plate 17 and the semi-circular ring b52 are in a tight state, so that the wedge block a20 can be re-inserted into the inner side of the limit groove 521, thereby completing the fixed connection between the semi-circular ring b52 and the semi-circular ring a51.

[0035] A horizontal base plate 11 is provided on one side of the bottom end of the frame 1, and an inclined plate 10 is obliquely provided on one end of the horizontal base plate 11 adjacent to the frame 1. Airbag cushions 12 are installed on the inclined plate 10 and the horizontal base plate 11. The horizontal base plate 11 and the inclined plate 10 are used to receive the fallen pipes, and the airbag cushions 12 can prevent the pipes from being damaged.

[0036] When inspecting and repairing the pipeline, first pass the pipeline through the inner side of the two lifting ring mechanisms at the bottom, then use the power mechanism to drive the transmission belts 2 on both sides to rotate synchronously, thereby driving multiple lifting ring mechanisms to move, thereby realizing the lifting of the pipeline. When the pipeline moves to a height that is easy for the operator to reach, stop driving the pipeline to rise, and then inspect and repair the pipeline. At the same time, another operator can place the next pipeline to be inspected on the two lifting ring mechanisms at the bottom. After the inspection and maintenance work of the pipeline is completed, continue to drive the transmission belt 2 to rotate. At this time, the pipeline at the bottom moves to the inspection position, and the upper pipeline continues to move. When the connecting rod 25 After contacting the inclined surface of the guide plate 26, the push rod 24 is forced to move gradually inward, thereby driving the wedge block b23 to move, and the wedge block b23 squeezes the wedge block a20 to move, and then under the action of gravity, the movable end of the semicircular ring b52 rotates and separates from the semicircular ring a51, and the pipe after inspection and maintenance falls off, which plays the function of automatic unloading; in summary, the technical solution installs multiple sets of lifting ring mechanisms on the transmission belt 2, so that the material discharge and unloading work can be carried out simultaneously during the inspection and maintenance work, and the unloading is automated and does not require manual operation. The low-place pipe can be lifted to a high place by driving the transmission belt 2 to move, eliminating the complicated manual handling process and saving time and effort.

[0037] Embodiment 2

[0038] likeFigure 1 and Figure 3 As shown in Figure 3 , a pipeline maintenance construction device proposed in this embodiment, compared with the first embodiment, in this embodiment, guide rails 14 are provided on the inner sides of the drive belts 2 on both sides. The guide rails 14 are fixedly connected to the frame 1. The guide rails 14 are arranged in a circle along the path direction of the drive belts 2. A chute 141 is formed in the guide rails 14, and the end of the sliding connection block 15 is slidably installed in the chute 141. The arranged guide rails 14 can play a guiding role in the movement of the sliding connection block 15. On the one hand, it can ensure the stability of the movement of the lifting ring mechanism. On the other hand, when the pipeline moves to the upper position, the arranged guide rails 14 can support the lifting ring mechanism. When the pipeline moves to the bottom position, the arrangement of the guide rails 14 can prevent the bottom end of the drive belt 2 from being deformed and cracked due to excessive force.
