Abstract
Description
Technical Field
[0001] This utility model relates to the field of heating pipelines, and in particular to a pressure testing device for heating pipelines. Background Technology
[0002] Pressure testing of heating pipes, also known as heating pipe pressure testing, is a common pipe inspection method. It is primarily used to ensure that the heating system pipes can withstand a certain pressure after installation or maintenance without leakage. This test verifies the sealing, strength, and safety of the pipes and their connecting components, preventing leaks or excessively low pressure after the system is put into use.
[0003] When connecting traditional heating hoses to pressure pumps, differences in hose size can lead to unstable connections and affect the pressure test results. To address this mismatch, traditional solutions often involve clamping the heating hose to the pressure pump using wire or clamps. However, this method is cumbersome and lacks overall practicality.
[0004] Therefore, a pressure testing device for heating pipes is provided to solve the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a heating pipe pressurization detection device, which realizes the rapid connection between the heating hose and the pressure pump equipment by setting a pipe connection structure.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A pressure testing device for heating pipes includes a mobile work platform;
[0008] The upper surface of the mobile work platform is equipped with a pressure pump body, and a water supply pipe is connected to one side of the pressure pump body.
[0009] The other end of the water supply pipe is equipped with a pipe connection structure, and a heating hose is installed on the pipe connection structure. The heating hose is connected to the water supply pipe.
[0010] The pipe connection structure includes a positioning shaft, a spool integrally provided on the side of the positioning shaft, a positioning plate embedded in the spool, and four bite plates arranged around the center of the side of the positioning plate, with the ends of the four bite plates all being conical.
[0011] An adjusting shaft is rotatably provided inside the positioning shaft, and an inner conical surface is provided on the inner wall of the adjusting shaft, which surrounds the bite piece.
[0012] A bracket is mounted on the upper surface of the mobile work platform, and a heating pressure pump control box is mounted on the side of the bracket. The heating pressure pump control box is electrically connected to the pressure pump body.
[0013] The bottom of the mobile work platform is equipped with four sets of omnidirectional wheels arranged in a rectangular pattern.
[0014] Furthermore, a pressure gauge is installed on the pressure pump body; the pressure gauge is used to detect the pressure of the heating pipeline.
[0015] Furthermore, one side of each of the four bite pieces is fixedly disposed on the side of the positioning groove, and the other end is separated; a rubber pad is adhered to the separated end of each of the four bite pieces.
[0016] Furthermore, an internal thread is engraved inside the positioning shaft, and an external thread is engraved outside the adjusting shaft; the internal thread and the external thread are compatible.
[0017] Furthermore, four inner ear plates are arranged around the center of the inner wall of the spool, and four positioning grooves are arranged around the outer side of the positioning plate. The inner ear plates and the positioning grooves are fitted together.
[0018] Furthermore, both the positioning plate and the adjusting shaft have through-holes on their sides, and the two through-holes have the same diameter.

It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.
[0027] First embodiment;
[0028] Reference Figure 1-3 As shown, a heating pipeline pressure testing device is provided in a preferred embodiment of the present invention, including a mobile work platform 1;
[0029] A pressure pump body 2 is mounted on the upper surface of the mobile workbench 1, and a water supply pipe 21 is connected to one side of the pressure pump body 2.
[0030] The other end of the water supply pipe 21 is equipped with a pipe connection structure 3, and a heating hose 22 is installed on the pipe connection structure 3. The heating hose 22 is connected to the water supply pipe 21.
[0031] The pipe connection structure 3 includes a positioning shaft 31 set in 16. A spool 32 is integrally set on the side of the positioning shaft 31. A positioning plate 37 is embedded in the spool 32. Four bite pieces 39 are arranged around the center of the side of the positioning plate 37. The ends of the four bite pieces 39 are all tapered.
[0032] An adjusting shaft 34 is rotatably provided inside the positioning shaft 31. An inner conical surface 36 is provided on the inner wall of the adjusting shaft 34, and the inner conical surface 36 surrounds the bite piece 39.
[0033] A support frame 4 is mounted on the upper surface of the mobile workbench 1, and a heating pressure pump control box 5 is mounted on the side of the support frame 4. The heating pressure pump control box 5 is electrically connected to the pressure pump body 2.
[0034] The bottom of the mobile work platform 1 is equipped with four sets of omnidirectional wheels arranged in a rectangular pattern.
[0035] In this embodiment, the mutual movement and cooperation of multiple structures within the pipe connection structure 3 allows for a quick and tight connection between the heating hose 22 and the water supply pipe 21. During use, the several ring-shaped clamps 29 within the pipe connection structure 3 tightly limit the heating hose 22, ensuring a consistently sealed connection with the water supply pipe 21. Compared to traditional wire clamping, the pipe connection structure 3 significantly simplifies the connection process between the heating hose 22 and the pressure pump body 2, making installation and disassembly faster and more convenient. Operators simply need to adjust the pipe connection structure 3 and fit the four clamps 39 onto the connection between the water supply pipe 21 and the heating hose 22, then tighten to complete the installation. Disassembly is also straightforward, requiring only readjustment of the pipe connection structure 3. This rapid installation mechanism saves installation time and manpower, improves work efficiency, and the ring-shaped clamping connection applies clamping force evenly, ensuring a good seal between the heating hose 22 and the water supply pipe 21 and reducing the risk of leakage.
[0036] Furthermore, the inclusion of casters significantly enhances the mobility and flexibility of the pressure testing equipment, allowing for easier movement and repositioning within the working environment. This is particularly important for equipment requiring frequent changes in work area, reducing labor intensity during transport and improving work efficiency. It is especially suitable for the inspection or maintenance of large heating systems, effectively improving repair efficiency.
[0037] Second embodiment;
[0038] Reference Figure 1-3 As shown, a pressure gauge is installed on the pressure pump body 2; the pressure gauge is used to detect the pressure of the heating pipe. During use, when the heating hose 22 is connected to the water supply pipe 21, the user can drive the heating pressure pump control box 5, thereby turning on the pressure pump body 2. Water is then injected into the heating hose 22 through the pressure pump body 2, simultaneously pressurizing the hose. With the help of the pressure gauge installed on the pressure pump body 2, the pressure of the heating hose 22 can ultimately be tested.
[0039] The sealing performance of the heating hose 22 can be effectively tested by pressurizing the pressure pump body 2. During pressurization, the pressure gauge can monitor the pressure changes inside the pipe in real time. If a leak occurs in the pipe, the pressure will drop rapidly. This allows for early detection of potential leaks and prevents future malfunctions and safety hazards. The pressure pump body 2 is electrically connected to the heating pressure pump control box 5, which can be used to control the start and stop of the pressure pump body 2. In use, both the pressure pump body 2 and the heating pressure pump control box 5 are existing mature structures, and their power connection methods are existing technologies. Furthermore, the control circuit and synchronous rotation method can be implemented by those skilled in the art through simple programming, which is common knowledge in the field. Since they are only used and not modified, the control method and circuit connection will not be described in detail.
[0040] Third embodiment;
[0041] Reference Figure 2-3 As shown, four bite plates 39 are fixedly mounted on one side of the positioning groove 38, and their other ends are separated. A rubber gasket is adhered to the separated ends of each of the four bite plates 39. The rubber gaskets at the ends of the bite plates 39 ensure a tighter connection between the water supply pipe 21 and the heating hose 22. The gaskets also provide a better seal for the wires, ensuring that there are no gaps between the water supply pipe 21 and the heating hose 22 after they are connected. The rubber gaskets within the pipe connection structure 3 provide dustproof and waterproof protection, thus better resisting the influence of environmental factors and ensuring good connection performance under different working conditions.
[0042] Fourth embodiment;
[0043] Reference Figure 2-3 As shown, an internal thread 33 is engraved inside the positioning shaft 31, and an external thread 35 is engraved on the outside of the adjusting shaft 34; the internal thread 33 and the external thread 35 are matched. Through the threaded engagement between the internal thread 33 and the external thread 35, the adjusting shaft 34 can be rotated and adjusted within the positioning shaft 31.
[0044] Fifth embodiment;
[0045] Reference Figure 2-3 As shown, four inner ear plates 310 are arranged around the center of the inner wall of the spool 32, and four positioning grooves 38 are arranged around the outer side of the positioning plate 37. The inner ear plates 310 and the positioning grooves 38 fit together. The fitting connection between the inner ear plates 310 and the positioning grooves 38 allows the positioning plate 37 to be detachably installed within the adjusting shaft 34. In a preferred embodiment, the connection between the positioning plate 37 and the adjusting shaft 34 can also be replaced by a bolt connection.
[0046] Sixth embodiment;
[0047] Reference Figure 2-3 As shown, both the positioning plate 37 and the adjusting shaft 34 have through-holes 311 on their sides, and the two through-holes 311 have the same diameter. After the heating hose 22 is inserted into the through-hole 311, the user connects the heating hose 22 to the water supply pipe 21 within the through-hole 311, ensuring that the end of the heating hose 22 is fitted over the outside of the water supply pipe 21. Subsequently, by adjusting the pipe connection structure 3, the user can ensure that the heating hose 22 is tightly fitted over the outside of the water supply pipe 21 and remains connected to it.
[0048] Specific implementation process:
[0049] Step 1: When the user needs to perform a pressure test on the heating hose 22, first insert one end of the heating hose 22 into the pipe connection hole 311 at the positioning plate 37 until the end of the heating hose 22 passes through the spool 32 and exits from the pipe connection hole 311 at the end of the adjusting shaft 34.
[0050] Step 2: After the heating hose 22 is inserted into the pipe connection hole 311, the user connects the heating hose 22 to the water supply pipe 21 in the pipe connection hole 311 and makes the end of the heating hose 22 fit over the outside of the water supply pipe 21. At this time, the four bite plates 39 set in the pipe connection structure 3 are located outside the interface between the water supply pipe 21 and the heating hose 22.
[0051] Step 3: After the heating hose 22 is fitted onto the outside of the water supply pipe 21, the user can rotate the adjusting shaft 34. Through the threaded connection between the adjusting shaft 34 and the positioning shaft 31, the adjusting shaft 34 can slide into the spool 32. As the adjusting shaft 34 gradually enters the spool 32, the inner conical surface 36 inside the adjusting shaft 34 will gradually squeeze the bite plates 39, so that the four bite plates 39 can move in a ring clamping motion until the four bite plates 39 can clamp the heating hose 22 and the water supply pipe 21 at the interface. This ensures that the heating hose 22 is tightly fitted onto the outside of the water supply pipe 21 and remains connected to the water supply pipe 21, preventing the connection between the heating hose 22 and the water supply pipe 21 from falling off or loosening when the heating hose 22 is stretched.
[0052] Step 4: After the heating hose 22 is connected to the water supply pipe 21, the user can drive the heating pressure pump control box 5 to turn on the pressure pump body 2. At this time, water is injected into the heating hose 22 through the pressure pump body 2, and the heating hose 22 is pressurized. With the help of the pressure gauge installed on the pressure pump body 2, the pressure test of the heating hose 22 can be achieved.
[0053] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
