Description

Technical Field

[0001] This utility model relates to the field of clamps, specifically a flange pipe clamp. Background Technology

[0002] Flange clamps are generally used for connecting flanged pipe ends to keep the connection position stable.

[0003] During prolonged use, the nuts on the clamps can easily become loose. Therefore, maintenance personnel need to perform regular maintenance along the direction of the pipeline. However, due to the large number of clamps, it is easy to miss or over-maintain them, leading to leaks. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flange pipe clamp, including an upper clamp, with a lower clamp rotatably mounted on one end of the upper clamp. The non-rotating ends of the upper and lower clamps are integrally formed with outwardly protruding parts. Both protruding parts have slots inside, with one end of the slot having an open structure. A rotating stud is rotatably mounted inside the upper slot. A locking nut is threadedly connected to the lower outer wall of the rotating stud in a vertical state. The locking nut in a tightened state is used to press the lower protruding part. A sensing mechanism is installed inside the lower protruding part.

[0007] As a further embodiment of this utility model: the sensing mechanism further includes a mounting bracket fixedly installed at the bottom end of the lower protrusion. The mounting bracket has a circular hole inside, and the protrusion has a screw hole that communicates with the bottom end of the receiving groove. The screw hole and the circular hole are aligned vertically. The outer shell of the pressure sensor passes through the circular hole and is threadedly connected to the screw hole.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-3 In this embodiment of the utility model, a flange pipe clamp includes an upper clamp 1, a lower clamp 2 rotatably mounted on one end of the upper clamp 1, and an outwardly protruding part 3 integrally formed on the non-rotating ends of the upper clamp 1 and the lower clamp 2. Both protruding parts 3 have slots inside, one end of which is open. A rotating stud 4 is rotatably mounted inside the upper slot. A locking nut 5 is threadedly connected to the lower outer wall of the vertical rotating stud 4. The locking nut 5 in the tightened state is used to press the lower protruding part 3. A sensing mechanism is installed inside the lower protruding part 3.

[0017] In this embodiment: when the device is connected to the mating ends of two flange pipes, the upper clamp 1 and the lower clamp 2 are clamped to the mating ends of the two flange pipes. Then, the stud 4 is rotated downwards. The stud 4 is rotated through the slot to the lower protrusion 3. Then, the locking nut 5 is used. After the locking nut 5 is fully tightened, the upper clamp 1 and the lower clamp 2 are tightly clamped to the mating ends of the two flange pipes, and the upper protrusion 3 is tightly pressed against the upper part of the lower protrusion 3. At this time, the sensing mechanism is tightly pressed. When the locking nut 5 becomes loose, the sensing mechanism can detect it to avoid continuous loosening.

[0018] Please refer to this carefully. Figure 2 and Figure 3 The sensing mechanism includes a receiving groove 6 inside the lower protrusion 3. The top of the receiving groove 6 is open. A sliding block 7 is slidably installed on the inner wall of the receiving groove 6. A guide rod 8 is fixedly installed on the inner wall of the receiving groove 6. The bottom plate of the sliding block 7 is slidably connected to the outer wall of the guide rod 8. A spring 9 abuts between the bottom end of the bottom plate of the sliding block 7 and the bottom end of the inner wall of the receiving groove 6. The spring 9 is sleeved on the outer periphery of the guide rod 8. The sensing mechanism also includes a mounting bracket 10 fixedly installed at the bottom end of the lower protrusion 3. A round hole is opened inside the mounting bracket 10. A screw hole communicating with the bottom end of the receiving groove 6 is opened inside the protrusion 3. The screw hole and the round hole are aligned vertically. The outer shell of the pressure sensor 11 passes through the round hole and is threadedly connected to the screw hole. A hexagonal limiting block is integrally formed below the outer shell of the pressure sensor 11.

[0019] In this embodiment: during the clamping process of the upper clamp 1 and the lower clamp 2, the upper clamp 1 drives the upper protrusion 3 to gradually approach the lower protrusion 3 until the upper protrusion 3 contacts the top of the sliding block 7 and is squeezed. The pressed sliding block 7 moves downward inside the receiving groove 6. The downward moving sliding block 7 squeezes the spring 9 and moves downward along the outer wall of the guide rod 8 until the two protrusions 3 are connected. At this time, the sliding block 7 applies pressure to the sensing end of the pressure sensor 11. The pressure sensor 11 can convert the pressure signal into an electrical signal and output it to the controller. At this time, the controller does not control the operation of the pre-connected alarm light.

[0020] If the locking nut 5 becomes loose, a gap will appear between the upper clamp 1 and the lower clamp 2. The spring 9 will then push the sliding block 7 to return to its original position. At this time, the pressure applied to the pressure sensor 11 by the bottom of the sliding block 7 will change. The pressure sensor 11 will then send an electrical signal to the controller again. The controller will then control the alarm light that is electrically connected to it to sound an alarm, providing instructions to maintenance personnel and preventing incorrect or missed maintenance.

[0021] Please refer to this carefully. Figure 3The mounting bracket 10 has a planar structure at the contact position with the limiting block.

[0022] In this embodiment: In this design, when the pressure sensor 11 is installed, the thread on the outer shell of the pressure sensor 11 can be threaded to the threaded hole until the limiting block effectively abuts against the position of the planar structure, which can limit the position of the sensing end of the pressure sensor 11 after installation.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
