Abstract

This utility model discloses a pipe fixing device for buried water conservancy pipelines, relating to the field of water conservancy pipeline technology. It includes a support plate, a support frame mounted on the top of the support plate, a V-shaped placement groove on the top of the support frame, guide frames fixedly mounted on both ends of the support frame, limit holes on the guide frames, a first through hole on the support plate adapted to a helical rod, and a pressure frame mounted on both ends of the helical rod. The helical rod passes through the limit hole and the first through hole in sequence and is connected to a fixing nut. The pressure frame is inverted V-shaped, and a pipe fitting is installed between the placement groove and the pressure frame.

Smaller diameter pipes will be positioned at the lower end of the V-shaped groove, while larger diameter pipes will be pushed upwards, with the contact point close to the groove opening. This allows the V-shaped structure to naturally adapt to changes in pipe diameter by changing the height of the contact point, without the need for additional adjustment structures.

Description

Technical Field

[0001] This utility model relates to the field of water conservancy pipeline technology, specifically a water conservancy pipeline buried pipe fixing device. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Water conservancy projects require water pipelines, some of which are buried pipes, and buried pipes need to be fixed by fixing devices.

[0003] Chinese utility model patent application number 202420253328.3 provides a pipe fixing device for buried water conservancy pipelines. It utilizes brackets and support blocks to provide three support points for the water conservancy pipeline, increasing the contact area between the pipeline and the brackets, reducing the pressure between them, and making the structure more stable. Furthermore, the support blocks effectively prevent the pipeline from rolling after it is hoisted into place, thereby improving the pipeline's stability and reducing the difficulty of subsequent locking and installation.

[0004] However, during the use of the above equipment, it was found that the bracket has multiple sets of mounting holes that match the support rods, which can adjust the distance between the support block and the center point of the bracket. By setting two first nuts, the height of the support block can be adjusted. The arc-shaped surface on the support block matches the outer wall of the water pipe. As a result, when dealing with water pipes of different diameters, in order to ensure that the support block fits perfectly with the outer wall of the water pipe, it is necessary to adjust the position of the support rod in each fixing device, which leads to a lot of wasted time and affects the efficiency of construction or maintenance. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a pipe fixing device for buried water conservancy pipelines, which solves the problem mentioned in the background art that when dealing with water conservancy pipelines of different diameters, it is necessary to adjust the position of the support rod in each fixing device, resulting in a lot of wasted time and affecting construction or maintenance efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water conservancy pipeline buried pipe fixing device, comprising a support plate, a support frame installed on the top of the support plate, a V-shaped placement groove opened on the top of the support frame, guide frames fixedly installed at both ends of the support frame, a limit hole opened on the guide frame, a first through hole opened on the support plate, the first through hole being adapted to a spiral rod, the left and right ends of the spiral rod being installed, the spiral rod passing through the limit hole and the first through hole in sequence and being connected to a fixing nut, the pressure frame being inverted V-shaped, and a pipe fitting installed between the placement groove and the pressure frame.

[0008] Preferably, the support plate has a second through hole.

[0009] Preferably, a mounting rod is fixedly provided at the bottom of the support frame, the mounting rod is adapted to correspond to the second through hole, and the mounting rod passes through the second through hole and is connected to the fixing nut.

[0010] Preferably, support rods are fixedly installed at the bottom of both the left and right ends of the support plate, and an inclined support rod is welded to one side of the support rod, which is connected to the bottom of the support plate.

[0011] Preferably, the support rod is fixedly installed on the base, the base has a positioning hole, and an anchor rod is connected in the positioning hole of the base.

[0012] This utility model provides a pipe fixing device for buried water conservancy pipelines. It has the following beneficial effects:

[0013] (1) By setting a V-shaped structure, when pipes of different diameters are placed in the V-shaped groove, the pipe with a smaller diameter will be located at the lower position of the V-shaped groove, while the pipe with a larger diameter will be supported upwards, with the contact point close to the groove opening. This allows the V-shaped structure to naturally adapt to changes in pipe diameter by changing the height of the contact point, without the need for additional structural adjustments.

[0014] (2) In this utility model, the second perforation provides a through channel for the mounting rod, so that the support frame can be fixedly connected to the support plate through the mounting rod, which facilitates the disassembly and installation of the support frame. At the same time, the inclined support rod is welded between the support rod and the bottom of the support plate to form a triangular support structure, which can enhance the resistance to deformation of the support plate, disperse the vertical load borne by the support rod, avoid excessive force on a single support point, and extend the service life of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0022] Example 1:

[0023] Please see Figures 1-5 This utility model provides a water conservancy pipeline buried pipe fixing device, including a support plate 1, a support frame 2 installed on the top of the support plate 1, a V-shaped placement groove 21 opened on the top of the support frame 2, guide frames 22 fixedly installed on both the left and right ends of the support frame 2, a limit hole 23 opened on the guide frame 22, a first through hole 12 opened on the support plate 1, the first through hole 12 is adapted to the spiral rod 5, the spiral rod 5 is installed on the left and right ends of the pressure frame 4, the spiral rod 5 passes through the limit hole 23 and the first through hole 12 in sequence and is connected to the fixing nut, the pressure frame 4 is inverted V-shaped, and a pipe fitting 3 is installed between the placement groove 21 and the pressure frame 4;

[0024] The top of the pressure frame 4 is provided with a reinforcing rib 41;

[0025] A second through hole 11 is provided on the support plate 1;

[0026] A mounting rod 24 is fixedly installed at the bottom of the support frame 2. The mounting rod 24 is adapted to the second through hole 11 and passes through the second through hole 11 to be connected to the fixing nut.

[0027] Support rods 13 are fixedly installed at the bottom of both the left and right ends of the support plate 1. An inclined support rod 14 is welded to one side of the support rod 13, and the support rod 14 is connected to the bottom of the support plate 1.

[0028] The support rod 13 is fixedly installed on the base 15, and the base 15 has a positioning hole, into which the anchor rod 16 is connected.

[0029] Specifically, the mounting rod 24 fixed at the bottom of the support frame 2 cooperates with the second through hole 11 opened on the support plate 1 to achieve precise positioning and connection. The mounting rod 24 can pass smoothly through the second through hole 11, and then the two are fixed by the fixing nut, so that the support frame 2 and the support plate 1 form a stable rigid connection structure.

[0030] The V-shaped placement groove 21 at the top of the support frame 2 and the inverted V-shaped pressure frame 4 form a symmetrical clamping structure. When the pipe fitting 3 is placed in the V-shaped placement groove 21, its outer wall will be in close contact with the two inclined sides of the V-shaped groove, providing initial support for the pipe fitting 3. Due to the characteristics of the V-shaped structure, regardless of the diameter of the pipe fitting 3, its outer wall will be in contact with the two inclined sides within a certain area. The pressure frame 4 achieves downward pressing through the screw rod 5, and the inverted V-shaped pressure frame 4 gradually moves downward, until its two inclined sides finally contact the upper surface of the pipe fitting 3. At this time, the upper and lower V-shaped structures together firmly clamp the pipe fitting 3 in the middle. The constraint force generated by the V-shaped placement groove 21 and the two inclined sides of the inverted V-shaped pressure frame 4 restricts the pipe fitting 3 from multiple directions. In the vertical direction, it prevents the pipe fitting 3 from moving upward or downward; in the radial direction, it can effectively restrict the rolling of the pipe fitting 3, so that the pipe fitting 3 is stably fixed in a specific position, ensuring that it will not easily shift or rotate during the operation of the hydraulic engineering project.

[0031] The spiral rod 5 passes sequentially through the limiting hole 23 on the guide frame 22 and the first through hole 12 on the support plate 1. Both ends of the spiral rod 5 are connected to the fixing nut. When the construction worker tightens the fixing nut, the spiral rod 5 experiences a downward pulling force, causing the pressure frame 4 to move downwards. As the fixing nut is continuously tightened, ultimately, under the synergistic effect of the spiral rod 5 and the fixing nut, the pressure frame 4 and the placement groove 21 tightly adhere to the outer wall of the pipe fitting 3, forming a rigid fixing effect. This ensures that even under the influence of external forces such as water flow impact and vibration during the long-term operation of the water pipeline, the fixing device can still maintain a stable clamping of the pipe fitting 3 and will not loosen.

[0032] The reinforcing rib 41 at the top of the pressure frame 4 enhances the bending resistance of the pressure frame 4: when the pressure frame 4 is subjected to downward tightening force and the reaction force of the pipe fitting 3, the reinforcing rib 41 can prevent the pressure frame 4 from deforming, ensure the clamping force is continuously stable, and extend the service life of the device.

[0033] The support rod 13 vertically supports the support plate 1, and the inclined support rod 14 is welded between the support rod 13 and the bottom of the support plate 1. The stability of the triangle is used to resist the gravity of the pipe 3 and the external impact force, prevent the support plate 1 from sagging or tilting, and ensure the structural rigidity of the entire fixing device.

[0034] The mounting rod 24 and the second through hole 11, and the spiral rod 5 and the first through hole 12 are all connected by fixing nuts to form a detachable structure: when it is necessary to replace the pipe fitting 3 or the maintenance device, the fixing nuts can be quickly removed to separate the pressure frame 4 and the support frame 2, which facilitates construction operations; at the same time, the detachable design allows the device to be disassembled into parts during transportation and installation, reducing transportation difficulty and improving construction efficiency.

[0035] Working principle: The mounting rod 24 at the bottom of the support frame 2 passes through the second through hole 11 of the support plate 1 and is fixed by the fixing nut, so that the support frame 2 is installed and fixed on the support plate 1. When the pipe 3 is placed in the V-shaped placement groove 21, its outer wall contacts the two inclined sides of the V-shaped groove to form initial support. After the pressure frame 4 is pressed down by the screw rod 5, the two inclined sides of the inverted V-shape contact the upper surface of the pipe 3. The upper and lower V-shaped structures together clamp the pipe 3 in the middle, and the constraint force of the two inclined sides restricts the vertical movement and radial rotation of the pipe 3.

[0036] The spiral rod 5 passes through the limiting hole 23 of the guide frame 22 and the first through hole 12 of the support plate 1, and is locked by the fixing nut. When the fixing nut is tightened, the spiral rod 5 pulls the pressure frame 4 downward, so that the inverted V-shaped structure of the pressure frame 4 is in close contact with the upper surface of the pipe fitting 3. The mechanical force of the threaded connection enhances the clamping force, ensuring that the pressure frame 4 and the placement groove 21 are in close contact with the outer wall of the pipe fitting 3, forming a rigid fixation.
