Description

Technical Field

[0001] This utility model relates to the field of building installation engineering technology, and in particular to a clamp device for installing underfloor heating pipes. Background Technology

[0002] With the widespread application of underfloor heating systems in residential and public buildings, their operational stability and installation reliability are receiving increasing attention. As a key component for heat energy transmission, underfloor heating pipes will undergo thermal expansion and contraction due to temperature changes during long-term use. If this physical deformation is not effectively controlled, it will damage the pipe connection points.

[0003] Currently, most common underfloor heating pipe installation methods use metal or plastic clamp structures, which are used to secure the pipes to the floor structure layer by bolting or embedding. However, traditional clamps do not have the ability to adapt to the thermal displacement of the pipes and only provide unidirectional fixing. When the underfloor heating pipes expand due to heat, the pipes will have a tendency to displace axially or radially, and the clamps cannot move with them. Instead, they become obstacles that restrict the displacement, leading to local stress concentration, which in turn causes the pipes to bend and deform or the clamp connection to fail.

[0004] Therefore, it is necessary to design a clamp device for installing underfloor heating pipes. Utility Model Content

[0005] In order to overcome the shortcomings of traditional clamps that cannot adapt to the thermal expansion displacement of underfloor heating pipes, which can easily lead to pipe deformation or clamp failure, this utility model provides a clamp device for underfloor heating pipe installation.

[0006] The technical solution of this utility model is as follows: a clamp device for installing underfloor heating pipes, comprising an installation base, guide columns, clamps, snap-fit ​​blocks, a first elastic element, a pull rod, and a locking structure. Guide columns are fixedly connected to the upper left and right sides of the installation base. Multiple slots are opened on the front and rear sides of the guide columns. The upper part of each slot is an inclined surface. A clamp is slidably connected between two guide columns. Snap-fit ​​blocks are slidably connected to the left and right sides of the clamp. One side of each snap-fit ​​block is an inclined surface. The inclined surface on the snap-fit ​​block is complementary to the inclined surface in the slot. The snap-fit ​​block and the slot engage. A first elastic element is connected between the snap-fit ​​block and the clamp. A pull rod is fixedly connected to the side of the snap-fit ​​block away from the center of the clamp. A locking structure is provided on both guide columns.

[0007] As a preferred technical solution of this utility model, the locking structure includes a locking plate, a screw, a push rod, and a second elastic element. A locking plate is placed on each of the two guide posts, and a screw is provided between the locking plate and the guide post on the same side. The screw is slidably connected to the locking plate and threadedly connected to the guide post. Push rods are slidably connected to the front and rear sides of the two locking plates. A second elastic element is connected between the push rod and the locking plate. The second elastic element is initially compressed, and the bottom of the push rod abuts against both sides of the clamp.

[0008] As a preferred technical solution of this utility model, it also includes a clamping plate, a pressure sensor, a third elastic element, and a control unit. Two pressure sensors are installed on the lower side of the middle part of the mounting base. A clamping plate is connected between the upper parts of the telescopic ends of the two pressure sensors. The lower side of the clamp is also provided with the same clamping plate. The two clamping plates are horizontally aligned, and the upper clamping plate is slidably connected to the clamping plate. The left and right sides of the lower clamping plate are connected to the mounting base with a third elastic element. A control unit is installed on the upper left side of the clamping plate. The control unit is electrically connected to the pressure sensor.

[0009] As a preferred technical solution of this utility model, it also includes a connecting frame and an electric push rod. The connecting frame is fixedly connected to the top of the clamp, and the electric push rod is installed at the bottom of the connecting frame. The lower telescopic end of the electric push rod is connected to the clamps that are close to each other, and the electric push rod is electrically connected to the control unit.

[0010] As a preferred technical solution of this utility model, it also includes a buffer pad, and buffer pads are provided on both clamps.

[0011] As a preferred technical solution of this utility model, the clamps are all semi-circular arc-shaped and have a certain degree of elasticity.

[0012] Beneficial effects:

[0013] 1. This utility model, by setting a clamp with a sliding snap-fit ​​structure and a guide column, enables the device to effectively cope with the axial deformation of the underfloor heating pipe caused by temperature changes, and slide up and down along the guide column within a certain range, avoiding pipe bending or clamp failure caused by improper clamp fixing.

[0014] 2. This utility model uses the linkage between the pressure sensor and the control unit to monitor in real time whether the pipeline is in the best clamping state, and combines the electric push rod to adjust the clamping force, thereby improving the reliability of operation.

Detailed Implementation

[0021] Example: A clamp device for installing underfloor heating pipes, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a mounting base 1, guide posts 2, clamps 3, snap-fit ​​blocks 4, first elastic elements 5, pull rods 6, and a locking structure. Guide posts 2 are fixed to the upper left and right sides of the mounting base 1. Multiple slots are provided on the front and rear sides of the guide posts 2. The upper part of each slot is an inclined surface. A clamp 3 is slidably connected between two guide posts 2. Snap-fit ​​blocks 4 are slidably connected to the left and right sides of the clamp 3. The side of the snap-fit ​​block 4 that is close to the guide post 2 is an inclined surface. The inclined surface on the snap-fit ​​block 4 is complementary to the inclined surface in the slot. The snap-fit ​​block 4 engages with the slot. A first elastic element 5 is connected between the snap-fit ​​block 4 and the clamp 3. A pull rod 6 is fixed to the side of the snap-fit ​​block 4 away from the center of the clamp 3. A locking structure is provided on both guide posts 2.

[0022] like Figure 2 As shown, the locking structure includes a locking plate 7, a screw 8, a push rod 9, and a second elastic element 10. A locking plate 7 is placed on each of the two guide posts 2. A screw 8 is provided between the locking plate 7 and the guide post 2 on the same side. The screw 8 is slidably connected to the locking plate 7 and threadedly connected to the guide post 2. Push rods 9 are slidably connected to the front and rear sides of the two locking plates 7. A second elastic element 10 is connected between the push rod 9 and the locking plate 7. The second elastic element 10 is initially compressed, and the bottom of the push rod 9 abuts against both sides of the clamp 3.

[0023] like Figure 1, Figure 4 and Figure 5 As shown, it also includes a clamping plate 11, a pressure sensor 13, a third elastic element 14, and a control unit 17. Two pressure sensors 13 are installed on the lower side of the middle part of the mounting base 1. The upper part of the telescopic ends of the two pressure sensors 13 are connected by a clamping plate 11. The lower side of the clamp 3 is also provided with the same clamping plate 11. The clamping plates 11 are all semi-circular and have a certain elasticity. The two clamping plates 11 are horizontally aligned vertically, and the upper clamping plate 11 is slidably connected to the clamp 3. The left and right sides of the lower clamping plate 11 are connected to the mounting base 1 by a third elastic element 14. The control unit 17 is installed on the upper left side of the clamp 3. The control unit 17 is electrically connected to the pressure sensor 13. All three elastic elements are springs.

[0024] like Figure 1 and Figure 5 As shown, it also includes a connecting frame 15 and an electric push rod 16. The connecting frame 15 is fixed to the top of the clamp 3, and the electric push rod 16 is installed at the lower part of the connecting frame 15. The lower telescopic end of the electric push rod 16 is connected to the clamping plates 11 that are close to each other, and the electric push rod 16 is electrically connected to the control unit 17.

[0025] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes a buffer pad 12, and both clamping plates 11 are provided with buffer pads 12.

[0026] In actual use, the operator must first loosen the screw 8 connected between the locking plate 7 and the guide post 2 by rotating it, and remove the entire locking structure from the guide post 2. Then, remove the clamp 3 from between the guide posts 2, and place the floor heating pipe on the clamp 11 in the lower middle of the mounting base 1. After completing the initial positioning, reinstall the clamp 3 between the guide posts 2 and restore the previously disassembled locking structure to its original position.

[0027] During the installation of clamp 3, the operator needs to pull the locking blocks 4 on both the front and rear sides away from each other, so that the first elastic element 5 is in a compressed state, thereby providing space for clamp 3 to slide along guide post 2. When clamp 3 slides to a suitable clamping position, release the locking blocks 4. Under the action of the first elastic element 5, the locking blocks 4 automatically reset and engage with the corresponding slots on guide post 2 to realize the dynamic positioning and self-locking function of clamp 3. Finally, reinstall the locking structure in place and fix it to guide post 2 by rotating screw 8 to ensure the overall structure is stable and reliable, and complete the installation of underfloor heating pipes.

[0028] When the local heating pipe expands due to heat, the clamping block 4 and the groove on the guide post 2 form a clamping fit, and the inclined surface on the clamping block 4 and the inclined surface in the groove are complementary. This allows the axial force generated by the expansion of the pipe to be effectively transmitted to the clamping system. At this time, the expansion force will push the upper and lower clamping plates 11 in contact with it to move relative to each other, and at the same time drive the clamping block 4 to move away from each other, causing the first elastic element 5 to be compressed.

[0029] As expansion continues, clamp 3 slides upward along guide post 2 to accommodate the increase in pipe diameter. During this process, the rise of clamp 3 also pushes top rod 9 to move upward synchronously, and the second elastic element 10 is compressed accordingly. The rebound force provided by this elastic element can keep top rod 9 in contact with clamp 3 and apply a certain downward pressure to prevent clamp 3 from detaching from guide post 2 or losing clamping stability due to excessive upward movement. After clamp 3 slides to the appropriate position, clamping block 4 is re-embedded in the new slot under the reset action of the first elastic element 5, realizing effective support and clamping of the pipe.

[0030] In addition, the clamp 11 will also move downward under the pressure of the pipe expansion. At the same time, due to its certain elastic deformation capacity, the clamp 11 will undergo outward expansion deformation and compress the third elastic element 14 set on its left and right sides. This structural design not only avoids local stress concentration caused by rigid constraints on the pipe, but also effectively reduces the risk of bending deformation caused by thermal expansion and contraction.

[0031] Meanwhile, the pressure sensor 13 continuously monitors the pressure value borne by the clamping plate 11 and transmits the detection signal to the control unit 17 in real time. When the clamping pressure is detected to be lower than the set threshold, the control unit 17 automatically starts the electric push rod 16 to drive the upper clamping plate 11 to move downward and increase the clamping force. Conversely, if the clamping force is too large, the control system adjusts the stroke of the electric push rod 16 in the opposite direction to prevent excessive squeezing from damaging the pipe and realizes intelligent feedback adjustment of the clamping force. Furthermore, the surface of the clamping plate 11 is provided with a buffer pad 12, which is made of a material with a certain degree of flexibility. This can ensure the clamping friction while avoiding scratches or indentations on the outer wall of the underfloor heating pipe, thereby improving the safety and reliability during the clamping process.

[0032] In summary, this invention achieves dynamic adaptation to thermal displacement of underfloor heating pipes and intelligent management of clamping force, significantly improving the stability of the installation structure and the operational safety of the system.
