Description

Technical Field

[0002] The fixing device for buried water and electricity pipes is a device used to fix the pipes buried underground during water and electricity construction. Water and electricity pipeline systems usually involve opening a channel on the ground and then burying the pipes in the channel. When burying the pipes, the pipes and the channel need to be fixed together by the fixing device.

[0003] Utility model patent CN218598992U discloses a fixing device for buried water and electricity pipelines. It includes a support mechanism for clamping and supporting the pipeline, a fixing mechanism for fitting and fixing the upper surface of the pipeline, and a support mechanism for supporting and adapting to the lower surface of the pipeline. This fixing device for buried water and electricity pipelines, by adjusting the fixing block of the fixing mechanism to be tangential to the pipeline, facilitates the fixing of pipelines of different diameters, expanding the application range of the pipeline fixing device. Simultaneously, the support block of the support mechanism can be rotated to a position tangential to the pipeline, facilitating stable support of pipelines of different diameters.

[0004] However, pipelines are affected by thermal expansion and contraction. Fixed installation and limiting methods can cause damage to the pipeline when it expands due to heat, and gaps will be created in the pipeline when it contracts due to cold, causing the pipeline to shake. The limiting effect is not good and it cannot adjust itself according to the thermal expansion and contraction of the pipeline. Utility Model Content

[0024] Example 1

[0025] Please refer to the attached document. Figure 1-3 This application provides a pipe fixing device, including a base 1, a bracket 2, and a buffer mechanism. The base 1 has symmetrically arranged fixing piles 3 at both ends, and a support seat 4 is provided on the base 1. The top of the support seat 4 has a first groove 5, and the corresponding bracket 2 is installed above the support seat 4. The bracket 2 has a second groove 6 with the same radius as the first groove 5. The bracket 2 has an arc-shaped inner cavity 7. The surface of the second groove 6 has a through hole 8. The buffer mechanism includes a clamping plate 9, a push rod 10, and a spring 11. The inner cavity 7 has an inner cylinder 12 along its outer side. The bottom of the push rod 10 has a third groove 13 that cooperates with the inner cylinder 12. One end of the spring 11 is fixedly connected to the bottom of the inner cylinder 12, and the other end is fixedly connected to the bottom of the third groove 13. The push rod 10 passes through the through hole 8 and is fixedly connected to the clamping plate 9. The bracket 2 is connected to the support seat 4 through a locking mechanism.

[0026] Place the base 1 at the location where the pipe needs to be fixed, and drive two fixing stakes 3 into the ground to secure the base 1. Place the pipe in the first groove 5 of the support base 4 to support the pipe. Place the bracket 2 on the support base 4 so that the space formed by the first groove 5 and the second groove 6 clamps the pipe. After aligning and fixing the bracket 2 with the support base 4, use the locking mechanisms at both ends of the bracket 2 to fix the bracket 2 and the support base 4 together, thus securing the pipe between the bracket 2 and the support base 4 and improving the pipe's fixing effect. During the locking process of the locking mechanism, the clamping plate 9 in the buffer mechanism contacts the top of the pipe. As the bracket 2 continues to move downward, the clamping plate 9... Moving outward along the diameter of the first groove 5, the push rod 10 simultaneously compresses the spring 11 inside the inner cavity 7 of the bracket 2, thereby limiting the top of the pipe. The spring 11 in the buffer mechanism can buffer the clamping plate 9. When the pipe expands and contracts due to heat, the clamping plate 9 can also effectively clamp the pipe. It can automatically adjust according to the changes in the pipe, and the clamping effect is good. At the same time, the buffering of the clamping plate 9 by the spring 11 can fix pipes of different diameters, expanding the application range of the pipe fixing device. The inner cylinder 12 is used to limit the buffer device and prevent the spring 11 from shifting when compressed, which would cause the buffer device to fail. The through hole 8 on the second groove 6 is used to limit the push rod 10.

[0027] Specifically, the bracket 2 has symmetrically arranged positioning blocks 14 at both ends of its bottom, and the support base 4 has a positioning groove 15 corresponding to the positioning blocks 14 at its top. The bracket 2 is aligned and installed by aligning the positioning blocks 14 at its bottom with the positioning grooves 15 on the support base 4, which serves to position the bracket 2. This operation is convenient and simple, improving the work efficiency of workers.

[0028] Specifically, a buffer pad 16 is provided on the first groove 5, and the buffer pad 16 is made of rubber. The buffer pad 16 is provided at the top of the first groove 5. The buffer pad 16 is a rubber component, and the rubber buffer pad 16 can protect the bottom of the pipe.

[0029] Specifically, the locking mechanism includes a first threaded through hole 17, a second threaded through hole 18, and a bolt 19. The support base 4 has the first threaded through holes 17 symmetrically arranged at both ends, and the bracket 2 has the second threaded through holes 18 symmetrically arranged at both ends corresponding to the first threaded through holes 17. The bracket 2 is connected to the support base 4 by the bolt 19 passing through the first threaded through holes 17 and the second threaded through holes 18. By turning the screw through the first threaded through hole 17 on the bracket 2 and the second threaded through hole 18 on the support base 4, the bracket 2 and the support base 4 are fixed together, thus securing the pipes inside the bracket 2 and the support base 4. Preferably, the bracket 2 has a locking mechanism at both ends.

[0030] Example 2

[0031] Please refer to the attached document. Figure 1-2 and attached Figure 4-5 The difference between this embodiment and Embodiment 1 is that the inner cylinder 12 has a limiting hole 20 on its side, and the inner wall of the third groove 13 has a limiting block 21. The limiting block 21 passes through the limiting hole 20 and is fixedly connected to the inner ring 22. The inner ring 22 is fixedly connected to the bottom of the third groove 13, and the inner cylinder 12 slides within the space formed by the inner ring 22 and the inner wall of the top rod 10. The inner ring 22 is provided in the third groove 13, which forms a clamping effect on the side wall of the inner cylinder 12 with the inner wall of the third groove 13, improving the stability of the buffer device. At the same time, the limiting block 21 on the inner ring 22 cooperates with the limiting ring on the side wall of the inner cylinder 12 to limit the buffer device and prevent the top rod 10 from misaligning with the inner cylinder 12 when the spring 11 returns to its original position, thus preventing the buffer device from failing.

[0032] Specifically, the second groove 6 is provided with three buffer mechanisms at equal intervals along the arc surface. The second groove 6 of the bracket 2 is provided with three buffer mechanisms tangent to the pipe, that is, the pipe is clamped and fixed at different positions around the circumference by three clamping plates 9. When the pipe expands and contracts due to heat, the pressure changes around the pipe can be buffered at different positions, thus playing the role of protecting the buffer device.

[0033] Specifically, the second groove 6 is provided with three buffer mechanisms at equal intervals along the axis. The second groove 6 of the bracket 2 is provided with three buffer mechanisms tangential to the pipe along the axis, that is, the pipe is clamped and fixed at different positions along the axial direction by three clamping plates 9. When the pipe expands and contracts due to heat, the pressure in the axial direction of the pipe can be buffered in segments, so as to avoid the failure of the device when a single buffer device is damaged, thereby improving the practicality of the device.

[0034] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
