Description
Technical Field
[0001] This utility model relates to the field of clamping for pipe assembly, specifically a pipe clamping device for building engineering. Background Technology
[0002] After two building pipes are connected, a clamping device is needed to fix them in place to ensure the sealing of the connection between the two pipes.
[0003] However, in the existing technology, the locking nuts of the clamping clamps may loosen during long-term use, so maintenance personnel need to tighten them regularly. However, this method requires maintenance personnel to tighten each locking nut one by one, which is a lot of work. Utility Model Content
[0004] The purpose of this utility model is to provide a pipe clamping device for building engineering in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe clamping device for construction engineering, comprising a first clamp and a second clamp rotatably connected to the first clamp. The first clamp has a first docking block integrally formed on the top of its docking end, and the second clamp has a second docking block integrally formed on the top of its docking end. A locking mechanism for limiting the first and second docking blocks is installed on the outside of the first docking block. A pressure mechanism is installed inside the first and second docking blocks to monitor whether the locking mechanism is loose.
[0006] As a further embodiment of this utility model: the locking mechanism includes a rotating seat integrally formed on the outside of the first docking block, a rotating bolt is rotatably installed on the inner side of the rotating seat, and a locking nut is threadedly connected to the outer wall of the rotating bolt.
[0007] As a further improvement of this utility model: the first docking block and the second docking block have slots inside to accommodate the rotating bolts, and the top of the slots is an open structure.
[0008] As a further embodiment of this utility model: the pressure mechanism includes a pressure rod slidably installed inside the second docking block, the outer circumference of the pressure rod is integrally formed with an outwardly protruding limiting ring, the inside of the second docking block is provided with a limiting groove for the limiting ring to slide, and the inside of the second docking block is provided with a cylindrical groove for the pressure rod to slide, both ends of the cylindrical groove are open.
[0009] As a further embodiment of this utility model: the pressure mechanism further includes a pressure sensor fixedly installed inside the first docking block, the sensing end of the pressure sensor extends into the interior of the cylindrical groove and is aligned with the pressure rod, and the output end of the pressure sensor is electrically connected to the controller through a wire.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] 1. By setting up a pressure mechanism, the design of the pressure mechanism can monitor the tightness of the locking nut. When the locking nut becomes loose, the pressure mechanism can trigger an alarm mechanism through the controller to tighten it, allowing maintenance personnel to perform targeted maintenance without having to tighten all locking nuts periodically, thus improving tightening efficiency.

[0016] 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.
[0017] Please see Figures 1-3 In this embodiment of the utility model, a pipe clamping device for construction engineering includes a first clamp 1 and a second clamp 2 rotatably connected to the first clamp 1. The top of the docking end of the first clamp 1 is integrally formed with a first docking block 3, and the top of the docking end of the second clamp 2 is integrally formed with a second docking block 4. A locking mechanism for limiting the first docking block 3 and the second docking block 4 is installed on the outside of the first docking block 3. A pressure mechanism is installed inside the first docking block 3 and the second docking block 4. The pressure mechanism is used to monitor whether the locking mechanism is loose.
[0018] In this embodiment: First, clamp 1 and clamp 2 are fastened to the two pipe connection ends. After clamp 1 and clamp 2 are tightened, the locking mechanism locks the connection block 3 and connection block 4. After effective locking, the locking mechanism applies a pressure exceeding the preset minimum pressure threshold to the pressure mechanism. At this time, the pressure mechanism sends an electrical signal to the controller. The controller does not control the alarm mechanism (such as alarm light or buzzer). If the locking mechanism becomes loose during use, the pressure applied to the pressure mechanism is reduced. When the pressure drops to the minimum pressure threshold, the pressure mechanism sends an electrical signal to the controller. The controller controls the alarm mechanism to operate, which allows the staff to detect the loose locking mechanism and tighten it.
[0019] Please refer to this carefully. Figure 1 and Figure 2 The locking mechanism includes a rotating seat 5 integrally formed on the outside of the first docking block 3. A rotating bolt 6 is rotatably installed on the inner side of the rotating seat 5. A locking nut 7 is threadedly connected to the outer wall of the rotating bolt 6. The first docking block 3 and the second docking block 4 have slots inside to accommodate the rotating bolt 6. The top of the slot is an open structure.
[0020] In this embodiment: when using the locking mechanism to lock the first docking block 3 and the second docking block 4, rotate the rotating bolt 6 to rotate it into the slot, and then rotate the locking nut 7. During the rotation of the locking nut 7, it is rotated towards the second docking block 4 until the locking nut 7 is effectively tightened. During the tightening process of the locking nut 7, sufficient pressure is applied to the pressure mechanism, which can then monitor whether the locking nut 7 is in an effectively tightened state.
[0021] Please refer to this carefully. Figure 3 The pressure mechanism includes a pressure rod 9 slidably installed inside the second docking block 4. The outer circumference of the pressure rod 9 is integrally formed with an outwardly protruding limiting ring 10. The second docking block 4 has a limiting groove 11 for the limiting ring 10 to slide inside. The second docking block 4 also has a cylindrical groove for the pressure rod 9 to slide inside. Both ends of the cylindrical groove are open. The pressure mechanism also includes a pressure sensor 8 fixedly installed inside the first docking block 3. The sensing end of the pressure sensor 8 extends into the cylindrical groove and is aligned with the pressure rod 9. The output end of the pressure sensor 8 is electrically connected to the controller through a wire.
[0022] In this embodiment: During the tightening process of the locking nut 7, the locking nut 7 gradually approaches the pressure rod 9 and comes into contact with and is pressed against the pressure rod 9. The pressure rod 9, under pressure, moves into the cylindrical groove and gradually approaches the sensing end of the pressure sensor 8 until the locking nut 7 is effectively tightened. The locking nut 7 applies pressure to the pressure sensor 8 through the pressure rod 9. When the pressure exceeds the preset minimum pressure, the pressure sensor 8 sends an electrical signal to the controller. The controller does not activate the alarm mechanism at this time. During long-term use, if the locking nut 7 becomes loose, the force acting on the pressure sensor 8 decreases. When the pressure is less than the minimum pressure, the pressure sensor 8 sends an electrical signal to the controller. The controller activates the alarm mechanism, and the operator can quickly detect that the locking nut 7 is loose and tighten it accordingly.
[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.
