In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.

[0028] like Figures 1-5 As shown, this utility model provides an adjustable boiler maintenance pipe clamp for clamping boiler pipes 10, including a top plate 20, a clamping device 30 and a drive assembly 40.

[0029] The top plate 20 is arranged horizontally. A connecting hook 21 is fixedly installed on the top of the top plate 20. The connecting hook 21 is used to connect with external lifting equipment. The lifting equipment is existing technology, and its specific structure will not be described in detail here. A guide rail 22 is fixedly installed on the bottom of the top plate 20.

[0030] There are two clamping devices 30, which are respectively arranged on both sides of the top plate 20. Each clamping device 30 includes a movable plate 31, a support block 32, and a pressing mechanism 50. The movable plate 31 is mounted on the guide rail 22 and is slidably connected thereto, while the support block 32 is fixedly installed on the inner side of the movable plate 31. The pressing mechanism 50 is used to press downward against the inner wall of the boiler pipe 10.

[0031] The drive assembly 40 is used to control the two clamping devices 30 to move closer or further apart.

[0032] In the initial state, the top plate 20 is located directly above the boiler pipe 10, and the two clamping components are located on the outer sides of both ends of the boiler pipe 10.

[0033] The specific usage process of this utility model is as follows:

[0034] First, the operator controls the two clamping devices 30 to move closer to each other using the drive assembly 40 until the movable plate 31 contacts the end face of the boiler pipe 10. At this point, the support block 32 enters the interior of the boiler pipe 10.

[0035] Then, the staff controls the external lifting equipment to start, and the external lifting equipment drives the top plate 20 to move upward through the connecting hook 21 until the support block 32 contacts the inner wall of the boiler pipe 10.

[0036] Next, the staff controls the clamping mechanism 50 to start, and the clamping mechanism 50 presses down to press the inner wall of the boiler pipe 10, so that the boiler pipe 10 is not easy to shake. Therefore, this clamp can keep the boiler pipe 10 stable during transportation.

[0037] In one embodiment, the clamping mechanism 50 includes a guide rod 51, a slider 52, a one-way lead screw 53, and two clamping assemblies 60.

[0038] A guide rod 51 is longitudinally positioned below the support block 32, with its two ends fixedly connected to the movable plate 31 and the support block 32, respectively. A slider 52 is mounted on the guide rod 51 and slidably connected to it. A one-way screw 53 passes longitudinally through the slider 52, with its two ends rotatably connected to the movable plate 31 and the support block 32, respectively. The one-way screw 53 is threadedly connected to the slider 52, and a handle 54 is fixedly mounted on the bottom of the one-way screw 53.

[0039] Two clamping assemblies 60 are respectively disposed on both sides of the slider 52 and are used to clamp the inner wall of the boiler pipe 10. The clamping assembly 60 includes a movable rod 61 and a guide shaft 62. The middle part of the movable rod 61 is rotatably connected to the inner side of the movable plate 31 via a rotating shaft 64. The first end of the movable rod 61 contacts the inner wall of the boiler pipe 10, and the second end of the movable rod 61 has a guide groove 63. The guide shaft 62 is disposed in the guide groove 63 and contacts the inner wall of the guide groove 63. The guide shaft 62 is connected to the slider 52.

[0040] In the initial state, the slider 52 is located at the bottom of the guide rod 51, and at this time the first end of the movable rod 61 is close to the support block 32.

[0041] When the movable plate 31 contacts the end face of the boiler pipe 10, and the support block 32 enters the interior of the boiler pipe 10, the operator controls the one-way screw 53 to rotate through the handle 54. Under the action of the guide rod 51, the slider 52 will drive the guide shaft 62 to move upward. Under the action of the rotating shaft 64, the first end of the movable rod 61 will swing downward until the first end of the movable rod 61 presses against the inner wall of the boiler pipe 10. At this time, the first end of the movable rod 61 is tilted downward, applying downward pressure to the inner wall of the boiler pipe 10.

[0042] In this embodiment, the top of the support block 32 applies an upward supporting force to the inner wall of the boiler pipe 10, and the first ends of the two movable rods 61 apply downward pressure to the inner walls on both sides of the boiler pipe 10. In this way, the clamp can clamp the boiler pipe 10 at three points, making it less likely for the boiler pipe 10 to shake, thus making the subsequent transportation process more stable.

[0043] After the boiler pipe 10 is hoisted, the operator rotates the handle 54 in the opposite direction, and the slider 52 moves downward. The two movable rods 61 will automatically disengage from the inner wall of the boiler pipe 10. The drive component 40 then controls the two clamping devices 30 to move away from each other, so that the boiler pipe 10 is separated from the clamp.

[0044] It is worth noting that this clamp can be used with boiler pipes 10 of different specifications. The operator controls the handle 54 and the one-way screw 53 to rotate at different angles. Under the action of the guide rod 51 and the rotating shaft 64, the first end of the movable rod 61 will swing downward at different angles. Therefore, this clamp is adjustable. Even if the inner diameter of the boiler pipe 10 is different, the clamping mechanism 50 can press down on the inner wall of the boiler pipe 10.

[0045] In one embodiment, the guide shaft 62 is rotatably connected to the slider 52, and the guide shaft 62 makes rolling contact with the inner wall of the guide groove 63.

[0046] This design reduces the friction between the guide shaft 62 and the inner wall of the guide groove 63, making the use of this fixture smoother.

[0047] In one embodiment, the drive assembly 40 includes a bidirectional lead screw 41 and a motor 42. The threads at both ends of the bidirectional lead screw 41 have opposite helical directions. The bidirectional lead screw 41 passes laterally through two movable plates 31, and both ends are rotatably connected to the top plate 20. The two ends of the bidirectional lead screw 41 are threadedly connected to the two movable plates 31 respectively. The motor 42 is fixedly mounted on the top plate 20 and is used to control the rotation of the bidirectional lead screw 41. The motor 42 is electrically connected to an external control cabinet.

[0048] When the drive assembly 40 is working, the operator controls the motor 42 to start through the external control cabinet. The motor 42 will drive the bidirectional lead screw 41 to rotate. Since the spiral directions of the threads at both ends of the bidirectional lead screw 41 are opposite, the two clamping devices 30 will move closer or further apart under the action of the guide rail 22.

[0049] This drive component 40 has a simple structure, making it easy to manufacture and use.

[0050] In one embodiment, the top of the support block 32 is formed with a first arc-shaped surface 33, which is better adapted to the inner wall of the boiler pipe 10.

[0051] In one embodiment, the first end of the movable rod 61 is formed with a second arc-shaped surface 65, which is better adapted to the inner wall of the boiler pipe 10.

[0052] In one embodiment, rubber pads are fixedly installed on both the first arc-shaped surface 33 and the second arc-shaped surface 65. The design of the rubber pads can, on the one hand, prevent the support block 32 and the movable rod 61 from directly contacting the inner wall of the boiler pipe 10, thus protecting the boiler pipe 10; on the other hand, it can increase the friction, further preventing the boiler pipe 10 from shaking and improving the stability of the boiler pipe 10 during transportation.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.

[0054] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
