Description

Technical Field

[0001] This utility model relates to the field of pipeline installation technology, and in particular to a DRPO pipe connection and installation fixing device. Background Technology

[0002] DRPO pipe is a new type of composite pipe, mainly made of modified polyolefin (DRPO) material, combined with a steel-plastic composite structure or a double-walled hollow design, and is widely used in drainage, sewage, and municipal engineering fields. DRPO pipe uses modified polyolefin material, enhancing material properties through activated rigid particles and grafted elastomers. The outer wall often features spiral steel reinforcement or a double-wall structure. This design retains the corrosion resistance of plastic pipes while enhancing the pressure and impact resistance of the steel strip.

[0003] During pipeline laying, it is necessary to connect the various branch pipes. Since most pipes are circular and their centers must be collinear during connection, a fixing device is required to assist in the connection. A search reveals, for example, a pipe connection fixing device provided by patent publication number "CN221290949U," which includes a base with side fasteners on both sides of the top. Each side fastener has several evenly distributed positioning holes. A support base is fixedly connected between adjacent sides of two side fasteners, and a clamping mechanism is installed between the outer sides. The clamping mechanism includes fasteners, with pins installed between the fasteners and the positioning holes, and fasteners installed on the top of the fasteners. By placing the pipe to be connected on the elongated support base, the pipe is balanced, and the clamping mechanism on the base provides stable clamping, improving the stability of the pipe connection. Adjusting the position of the clamping mechanism on the base adapts to pipes of different lengths, and adjusting the distance between the pressure block and the support base adjusts the clamping pipe diameter, thus expanding the applicability of the device for fixing and connecting pipes.

[0004] Based on the above search and combined with the existing technology, it was found that the existing fixing devices similar to those disclosed above have poor surface performance when used for DRPO pipe connection and installation. This is mainly because the outer wall of the DRPO pipe is reinforced with spiral protruding steel strips, while the flat bottom pressure block is difficult to fit against all its outer surfaces, resulting in a small contact area and poor fixing effect. At the same time, applying pressure only to the protruding part of the DRPO pipe may cause local deformation due to pressure concentration, which may damage the DRPO pipe. Therefore, a DRPO pipe connection and installation fixing device is proposed to improve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a DRPO pipe connection and installation fixing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a DRPO pipe connection and installation fixing device, comprising a support base, a sliding frame slidably mounted on the support base, an adjusting screw threadedly connected to the sliding frame and vertically penetrating the sliding frame, and a pressure block rotatably connected to the lower end of the adjusting screw;

[0007] The pressure block includes a mounting block, a base pressure plate, and a movable pressure plate. The top of the mounting block is rotatably connected to the lower end of the adjusting screw. The base pressure plate is detachably installed at the bottom of the mounting block. Multiple fixed pressure plates are integrally formed at the lower end of the base pressure plate, and an installation gap is formed between the multiple fixed pressure plates. The movable pressure plate is movably inserted into the installation gap, and the lower end of the movable pressure plate is lower than the lower end of the fixed pressure plate.

[0008] The fixed pressure plate and the movable pressure plate can be detachably fixed by connecting parts.

[0009] As a further supplement to this solution, the connector includes a positioning bolt, which slides horizontally through the fixed pressure plate and the movable pressure plate, and the nut of the positioning bolt abuts against the outer side of the outermost fixed pressure plate. A wing nut is screwed onto the positioning bolt, and one side of the wing nut abuts against the outer side of the outermost movable pressure plate.

[0010] As a further supplement to this solution, both the fixed pressure plate and the movable pressure plate are provided with positioning holes for the positioning bolts to slide through. When the movable pressure plate is installed in the installation gap, the positioning holes on the fixed pressure plate and the positioning holes on the movable pressure plate coincide.

[0011] As a further supplement to this solution, a first magnet strip is fixedly embedded in the top wall of the installation gap, and a second magnet strip that is magnetically attracted to the first magnet strip is fixedly embedded in the top of the movable pressure plate. The second magnet strip corresponds to the vertical position of the first magnet strip.

[0012] As a further supplement to this solution, the bottom surface of the mounting block is provided with a connection hole, and the top of the base plate is fixed with a connecting stud, which is screwed into the connection hole.

[0013] As a further supplement to this solution, a guide rod is also fixed to the top of the mounting block, and the guide rod slides vertically through the sliding frame.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] 1. In this utility model, by decomposing the pressure block into three parts, and making the mounting block and the base pressure plate, as well as the base pressure plate and the movable pressure plate, detachable and fixed, and setting the lower end of the movable pressure plate to be lower than the lower end of the fixed pressure plate, a toothed pressure block structure with staggered top and bottom can be formed to adapt to the protrusion of the outer wall of the DRPO pipe. This not only increases the contact area but also achieves interlocking fixation, which can improve the stability of fixing the DRPO pipe. At the same time, it can apply pressure evenly to the outer surface of the DRPO pipe, thereby reducing the probability of local deformation or damage to the DRPO pipe and ensuring the quality of the DRPO pipe after installation.

[0016] 2. In this utility model, different movable pressure plates or base pressure plates can be replaced to adapt to different models of DRPO pipes, thus expanding the scope of application. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] Example: Reference Figure 1-3The DRPO pipe connection and installation fixing device shown includes a support base 1, a sliding frame 2 slidably installed on the support base 1, an adjusting screw 4 threadedly connected to the sliding frame 2 and vertically passing through the sliding frame 2, and a pressure block 3 rotatably connected to the lower end of the adjusting screw 4.

[0024] Among them, the support base 1, the sliding frame 2 and the adjusting screw 4 are all existing technologies. Their specific structures, possible auxiliary structures (such as positioning bolts for fixing the sliding frame 2), working principles, etc. are all disclosed in the prior art (including but not limited to the patent document with publication number "CN221290949U"), and will not be repeated here.

[0025] The pressure block 3 includes a mounting block 31, a base pressure plate 32, and a movable pressure plate 33. The top of the mounting block 31 is rotatably connected to the lower end of the adjusting screw 4. The base pressure plate 32 is detachably installed at the bottom of the mounting block 31. Multiple fixed pressure plates 321 are integrally formed at the lower end of the base pressure plate 32. An installation gap 322 is formed between the multiple fixed pressure plates 321. The movable pressure plate 33 is movably inserted into the installation gap 322, and the lower end of the movable pressure plate 33 is lower than the lower end of the fixed pressure plate 321.

[0026] The fixed pressure plate 321 and the movable pressure plate 33 are detachably fixed by a connector.

[0027] Based on the above structure, by decomposing the pressure block 3 into three parts (installation block 31, base pressure plate 32, and movable pressure plate 33), and making the installation block 31 and base pressure plate 32, as well as the base pressure plate 32 and movable pressure plate 33, both detachable and fixed, and setting the lower end of the movable pressure plate 33 to be lower than the lower end of the fixed pressure plate 321, a toothed pressure block structure with staggered bottom can be formed to adapt to the protrusion of the outer wall of the DRPO pipe. This not only increases the contact area but also achieves interlocking fixation, which can improve the stability of fixing the DRPO pipe. At the same time, it can apply pressure evenly to the outer surface of the DRPO pipe, thereby reducing the probability of local deformation or damage to the DRPO pipe and ensuring the quality of the DRPO pipe after installation.

[0028] In addition, staff can adapt to different models of DRPO pipes by changing different movable pressure plates 33 or base pressure plates 32, making it more widely applicable.

[0029] Furthermore, the connector includes a positioning bolt 6, which slides horizontally through the fixed pressure plate 321 and the movable pressure plate 33, and the nut part of the positioning bolt 6 abuts against the outer side of the outermost fixed pressure plate 321. A wing nut 61 is screwed onto the positioning bolt 6, and one side of the wing nut 61 abuts against the outer side of the outermost movable pressure plate 33.

[0030] Both the fixed pressure plate 321 and the movable pressure plate 33 are provided with positioning holes 34 for the positioning bolt 6 to slide through. When the movable pressure plate 33 is installed in the installation gap 322, the positioning holes 34 on the fixed pressure plate 321 and the positioning holes 34 on the movable pressure plate 33 coincide.

[0031] When it is necessary to replace the movable pressure plate 33 or adjust the gap between multiple movable pressure plates 33, the operator only needs to unscrew the wing nut 61 and pull out the positioning bolt 6 to remove the installed movable pressure plate 33. Then, adjust the installation position of the movable pressure plate 33, or continue to install another movable pressure plate 33. After installation, simply insert the positioning bolt 6 again and tighten the wing nut 61. The replacement operation is simple and facilitates the purpose of adjusting the gap of the movable pressure plate 33 or replacing different models of movable pressure plates 33, so that the pressure block 3 can adapt to the clamping and positioning requirements of different models of DRPO pipes (e.g., different external spiral protrusion gaps or different thicknesses).

[0032] Furthermore, a first magnet strip 7 is fixedly embedded in the top wall of the mounting gap 322, and a second magnet strip 8 that is magnetically attracted to the first magnet strip 7 is fixedly embedded in the top of the movable pressure plate 33. The second magnet strip 8 corresponds to the first magnet strip 7 in vertical position.

[0033] By setting the first magnet strip 7 and the second magnet strip 8, the movable pressure plate 33 can be pre-fixed by the magnetic attraction of the first magnet strip 7 and the second magnet strip 8 after being inserted into the installation gap 322. At the same time, it can achieve automatic positioning (the position is fixed when the first magnet strip 7 and the second magnet strip 8 are attracted to each other). This makes it easier for staff to install the movable pressure plate 33, saves the workload of calibration, and makes it more convenient to use.

[0034] Furthermore, the bottom surface of the mounting block 31 is provided with a connecting hole 311, and the top of the base plate 32 is fixed with a connecting stud 35. The connecting stud 35 is screwed into the connecting hole 311, thereby realizing the detachable connection between the base plate 32 and the mounting block 31. This allows the operator to disassemble and install the base plate 32 by rotating it, which facilitates the replacement of the base plate 32 to adapt to different models of DRPO pipes. Moreover, when replacing the base plate 32, multiple movable pressure plates 33 can be replaced simultaneously, making batch replacements faster and more convenient.

[0035] Furthermore, to prevent the mounting block 31 from rotating during vertical movement, which could cause the base plate 32 and the movable plate 33 to shift, a guide rod 5 is fixed to the top of the mounting block 31. The guide rod 5 slides vertically through the sliding frame 2, thereby ensuring that the mounting block 31 always maintains a fixed posture when driven by the adjusting screw 4, thus meeting the alignment requirements of the base plate 32 and the movable plate 33 with the external protruding thread of the DRPO pipe.

[0036] The working principle of this utility model is as follows: In daily use, the operator first adjusts and fixes the position of the sliding frame 2, then rotates the adjusting screw 4 to drive the pressure block 3 to rise. Then, the two DRPO tubes to be connected are inserted into the support base 1 from both ends and placed on the support base 1. At this time, the operator only needs to rotate the adjusting screw 4 in the opposite direction to drive the pressure block 3 to fall, so that the pressure block 3 and the support base 1 can cooperate to clamp the two DRPO tubes to be connected, which helps to connect and fix the DRPO tubes. When it is necessary to clamp and fix different models of DRPO tubes, the operator can replace different movable pressure plates 33 or base pressure plates 32 to adapt to different models of DRPO tubes, thus making the application range wider.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
