Description

Technical Field

[0001] This utility model relates to the field of pipeline tool technology, and in particular to a riser positioning tool for a heating system. Background Technology

[0002] Vertical pipes are often installed in centralized heating systems and industrial steam pipe networks. Due to long-term thermal stress and foundation settlement, the vertical pipes are prone to sinking or radial deformation, which can cause misalignment between the meter interface flange and the pipe connection, making it inconvenient to disassemble and install the meter during pipeline maintenance.

[0003] In current maintenance practices, when meters need to be replaced, temporary fixing tools such as chains and webbing are often used to secure the pipes. This is cumbersome, and it is difficult to guarantee the fixing strength, which affects construction safety. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing technologies, such as difficulty in fixing settled risers and inconvenience in fixing operations, and to propose a riser positioning tool for heating systems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A heating system riser positioning tool includes a pull rod assembly, wherein both ends of the pull rod assembly are connected to screws and claws;

[0007] The tie rod assembly includes a tie rod and threaded sleeves fixedly disposed on both sides of the tie rod. Two tie rods are symmetrically arranged, and the threaded rods are threadedly installed in the threaded sleeves.

[0008] The outer side of the clamp is provided with a clamp corresponding to the pipe, which is used to clamp onto the pipe flange.

[0009] Preferably, a pull ring is provided on the outer side of the screw, and a connecting hole is provided at the lower end of the claw corresponding to the pull ring and is movably connected to the pull ring.

[0010] Preferably, the pull rod is fitted with a grip for holding when rotating the pull rod assembly.

[0011] More preferably, the grip has clearance holes at both ends to avoid the screws on both sides.

[0012] More preferably, the upper and lower sides of the grip are milled flat.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the design of the pull rod assembly and the claw makes it easy to adjust and position the pipe opening, which facilitates the installation of the metering equipment on the heating pipeline and the adjustment of the riser position.

[0015] 2. In this utility model, the claw is installed on the pull rod assembly by a screw, which makes it easy to replace the claw with different clips, making it easy to adapt to pipes of different diameters and ensuring good compatibility;

[0016] 3. In this utility model, the sliding connection between the claw and the screw allows the claw to be easily fixed on the pipe opening, facilitating its use in actual construction environments.

[0017] This utility model has a simple structure, low manufacturing cost, and is relatively easy to manufacture. It is also convenient to use in practice, and can easily locate the pipe opening for installing meters and other equipment. It has good compatibility and is suitable for widespread use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4 A riser positioning tool for a heating system includes a pull rod assembly 1, with screws 2 and claws 3 connected to both ends of the pull rod assembly 1; the position of the claws 3 is adjusted by the cooperation of the pull rod assembly 1 and the screws 2, so as to adjust and fix the position of the riser.

[0025] The pull rod assembly 1 includes a pull rod 11 and threaded sleeves 12 fixedly disposed on both sides of the pull rod 11. Two pull rods 11 are symmetrically arranged, and the screw 2 is threadedly installed in the threaded sleeves 12. The two pull rods 11 ensure the stable installation of the threaded sleeves 12, ensure the structural position stability of the threaded sleeves 12 on both sides, and ensure the stable installation and adjustment of the screw 2.

[0026] The outer side of the clamp 3 is provided with a locking slot 32 corresponding to the pipe, which is used to clamp onto the pipe flange. The locking slot 32 engages with the flange, pipe clamp, or pipe groove on the riser, and the clamps 3 on both sides pull the pipes in place. At this time, rotating the pull rod assembly 1 in conjunction with the pull rod 11 allows adjustment of the distance between the two clamps 3 within a certain range, i.e., adjusting the distance between the pipes on both sides, facilitating the installation of meters on the riser. When dealing with pipes of different diameters, simply unscrew the screw 2 from the threaded sleeve 12 and replace it with a screw 2 connected to a suitable clamp 3.

[0027] Based on the above technical solution, when installing or replacing metering equipment on risers and other pipes in a heating system, first adjust the clamps 3 on both sides to a suitable distance, then clamp the clamps 3 onto the flanges or clamps of the pipe for fixation. When it is necessary to move the pipe opening distance inward or outward, rotate the tie rod assembly 1 in conjunction with the threaded sleeve 12 to drive the screw 2 inward or outward, thereby adjusting the position of the two pipe openings to facilitate the installation of the metering equipment. This effectively improves the installation of metering equipment in the heating system.

[0028] In this technical solution, such as Figure 1-4 As shown, a pull ring 21 is provided on the outer side of the screw 2, and a connecting hole 31 is provided at the lower end of the claw 3 corresponding to the pull ring 21 and is movably connected to the pull ring 21. This movable connection design allows the claws 3 on both sides to be easily engaged with the pipe during actual use, facilitating subsequent pipe adjustments and simplifying the use of this tool.

[0029] In this technical solution, such as Figure 1-4 As shown, a handle 4 is fitted onto the pull rod 11 for gripping when rotating the pull rod assembly 1. The handle 4 design facilitates the operator's grip when rotating the pull rod assembly 1, thus simplifying the use of this tool.

[0030] In this technical solution, such as Figure 1-4 As shown, the grip 4 has through holes 41 at both ends to avoid interference with the adjustment of the screws 2 on both sides. The design of the through holes 41 avoids the grip 4 from interfering with the adjustment of the screws 2 on both sides, and ensures the adjustment range of the spacing of the claws 3 on both sides.

[0031] In this technical solution, such as Figure 1-4As shown, the grip handle 4 has milled flats 42 on both the upper and lower sides. The milled flats 42 design ensures stable clamping of the tool on the grip handle 4 when tools such as wrenches are needed to rotate the lever 11, guaranteeing a good rotation effect.

[0032] 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.
