DETAILED DESCRIPTION
[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0026] Example 1
[0027] Reference Figure 1-2 , which is the first embodiment of the utility model, provides a transport device for laying pipelines, including a bracket 1, the bracket 1 has four legs, and is fixedly connected to a crossbar portion, the length of the crossbar can be changed according to the site where the pipeline is laid, and the angle between the legs and the ground can also be adjusted, so that the device can obtain the pipeline at a height above the ground and can remain stable on the ground, and the crossbar portion can replace the screw rod and be driven by an external motor, and a thread can also be set in the through hole 29, so that the crossbar in the bracket 1 can automatically transport the device horizontally, and the bracket 1 is fixedly connected to the crossbar;
[0028] It also includes a length adjustment structure arranged on the bracket 1;
[0029] The length adjustment structure includes a mounting rod 21 movably connected to the cross rod, the main part of the mounting rod 21 is a rectangular rod, and circular connecting blocks 22 are connected at both ends of the mounting rod 21, the connecting blocks 22 are fixedly connected to the two ends of the mounting rod 21, and the connecting blocks 22 are used to rotatably connect the first screw rod 25, a slide groove 23 is provided in the mounting rod 21, and a bidirectional motor 24 is fixedly connected to the middle position of the mounting rod 21, and two first screw rods 25 are connected at both ends of the bidirectional motor 24. Driving the bidirectional motor 24 can make the two first screw rods 25 rotate in different directions, the first screw rod 25 arranged on the bidirectional motor 24, a movable end 26 threadedly connected to the first screw rod 25, and the movable end 26 can move along the first screw rod 25, and a hydraulic telescopic rod 27 fixedly connected to the movable end 26, and the hydraulic telescopic rod 27 can be controlled by an external device to extend and retract in the vertical direction.
[0030] A slider 28 is fixedly connected to the upper side of the movable end 26 . The slider 28 and the slide groove 23 are used in conjunction with each other to limit the displacement direction of the movable end 26 .
[0031] The mounting rod 21 is provided with a through hole 29 , in which a cross bar is arranged, so that the mounting rod 21 can move on the cross bar of the bracket 1 , and an inner diameter adjustment structure is fixedly connected to the lower side of the hydraulic telescopic rod 27 .
[0032] During use, it is first necessary to move the mounting rod 21 so that the mounting rod 21 is displaced to the top of the pipeline. Some offset can be ignored. This process can be driven by an external power source or manually adjusted. Then the bidirectional motor 24 is driven. The bidirectional motor 24 drives the first screw rod 25 to rotate. Because the first screw rod 25 and the movable end 26 are threadedly connected, the rotation of the first screw rod 25 will drive the movable end 26 to move axially along the first screw rod 25. Because the two output ends of the bidirectional motor 24 rotate in different directions, the two movable ends 26 will move in opposite directions, that is, the inner diameter of the connection of the hydraulic telescopic rod 27 is adjusted according to the length of the pipeline. The adjustment structure is located on the outside of the port of the pipeline, generally about twenty centimeters away from the port. Then the hydraulic telescopic rod 27 is driven to extend the hydraulic telescopic rod 27, thereby lowering the inner diameter adjustment structure to the center of the pipeline. Some deviations can be ignored. Then stop driving the hydraulic telescopic rod 27, and rotate the bidirectional motor 24 in the opposite direction to make the first screw 25 move with the two movable ends 26 towards each other, so that the inner diameter adjustment structure enters the interior of the pipeline, but the hydraulic telescopic rod 27 does not touch the pipeline. Then the inner diameter adjustment structure is driven to support the pipeline. Finally, the installation rod 21 and the hydraulic telescopic rod 27 are moved to transport the pipeline to the position where it needs to be transported.
[0033] Example 2
[0034] Reference Figure 1-4 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: the inner diameter adjustment structure includes a motor seat 31 fixedly connected to the lower side of the hydraulic telescopic rod 27, the motor seat 31 has an area for mounting a built-in motor 33 inside, a mounting plate 32 fixedly connected to the motor seat 31, three mounting plates 32 fixedly connected to the motor seat 31, and the three mounting plates 32 are evenly arranged on the same surface, a built-in motor 33 fixedly connected to the motor seat 31, a rotating shaft 34 arranged on the built-in motor 33, a first bevel gear 35 fixedly connected to the rotating shaft 34, a second bevel gear 36 arranged on one side of the first bevel gear 35, the first bevel gear 35 is meshed with the second bevel gear 36, and the first bevel gear 35 is meshed with the three second bevel gears 36 at the same time.
[0035] A second screw rod 37 is fixedly connected to the second bevel gear 36, and the second screw rod 37 is rotatably connected to the mounting plate 32. The second screw rod 37 is threadedly connected to a connecting frame 38. The connecting frame 38 has two parts, a lower end of a threaded sleeve threadedly connected to the second screw rod 37, and an upper end of an L-shaped plate connected to the threaded sleeve. A grooved ball sleeve 39 is fixedly connected to the upper side of the connecting frame 38. The grooved ball sleeve 39 has an annular groove inside for mounting the ring on the groove ball 310. The groove ball 310 is movably connected to the inner side of the grooved ball sleeve 39. The annular groove in the grooved ball sleeve 39 and the ring on the groove ball 310 are used in combination to limit the groove ball 310 to rotate in only one direction.
[0036] The end of the second screw rod 37 is fixedly connected to a limit block 311, which is used to prevent the connecting frame 38 from overextending. The lower side of the connecting frame 38 is fixedly connected to a driven telescopic rod 312, which is used to install the connecting frame 38 on the mounting plate 32, so that the connecting frame 38 can be driven by the second screw rod 37.
[0037] During use, when the inner diameter adjustment structure enters the pipeline, the built-in motor 33 is driven, and the built-in motor 33 drives the rotating shaft 34 and the first bevel gear 35 to rotate, thereby driving the second bevel gear 36 meshing with the first bevel gear 35 to rotate. The second bevel gear 36 is fixedly connected to the second screw rod 37, so the second screw rod 37 can be driven to rotate. Since the second screw rod 37 and the threaded sleeve at the lower end of the connecting frame 38 are threadedly connected, the connecting frame 38 can be driven to move axially along the second screw rod 37, so that the groove ball 310 at the upper end of the connecting frame 38 can contact the inner wall of the pipeline. After contacting the inner wall of the pipeline, the built-in motor 33 is stopped. At this time, after the groove ball 310 presses against the inner wall of the pipeline, since the groove ball 310 cannot move in the same direction as the pipeline, and the groove ball 310 presses against the inner wall of the pipeline, it will not only play a supporting role on the pipeline, but also can exert increased friction on the pipeline in the same direction as the pipe, so as to avoid the pipeline from sliding during transportation.
[0038] When the pipeline is transported to the specified position through the length adjustment structure, the operator can rotate the pipeline. Since the groove ball 310 can rotate along the annular groove in the grooved ball sleeve 39, the upper and lower ends of the pipeline can be adjusted. After adjusting to the optimal position, the length adjustment structure and the inner diameter adjustment structure are driven to lower the pipeline.
[0039] The remaining structures are the same as those of Example 1.
[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
