[0034] like Figure 1 to Figure 2 As shown, the first embodiment of the utility model provides a rail pipe test device, comprising:

[0035] The pipe threading line 100 is suitable for being threaded through the rail pipe 102;

[0036] A cable 104, wherein the cable 104 is sleeved on the pipe 100 and has a diameter of at least 50 mm and a length of at least 800 mm;

[0037] The connection terminals 106 are disposed at both ends of the cable 104 and are crimped and adapted to the pipe-threading wire 100 .

[0038] According to the rail tube trial-insertion device provided by the embodiment of the first aspect of the utility model, by adopting the combined design of the pipe threading line 100 and the cable 104, the rail tube 102 can be efficiently tried. The pipe threading line 100 can be smoothly inserted into the rail tube 102, and the cable 104 can more accurately simulate the actual use situation due to its larger diameter and length, thereby ensuring that the rail tube 102 can meet the needs of actual use. The design of the terminal 106 enables the cable 104 and the pipe threading line 100 to be crimped and adapted. This design not only enhances the connection stability between the cable 104 and the pipe threading line 100, but also improves the versatility and adaptability of the entire device, and can adapt to the requirements of trying on rail tubes 102 of different specifications and materials. The entire device has a simple structure and is easy to operate, and the trial operation can be completed without complex tools or equipment. This greatly reduces the difficulty and cost of operation and improves work efficiency. By using this rail tube test device, the rail tube 102 can be pre-tested before the cable 104 is officially installed, and possible problems can be discovered and solved in time, thereby avoiding rework and delays in the actual installation process and improving construction efficiency and quality. Since potential problems can be discovered and solved during the test stage, the cost increase of damage and replacement of the cable 104 that may occur later is avoided, and the construction risk is also reduced.

[0039] Please continue to see Figure 1 and Figure 2 The pipe threading line 100 is one of the core components of the rail tube trial insertion device. Its diameter is designed to be moderate so that it can be easily inserted into the rail tube 102. The material of the pipe threading line 100 is usually selected from wear-resistant and tensile-resistant materials to ensure that it is not easily damaged during the trial insertion process, and at the same time has a certain flexibility to adapt to the rail tube 102 with different bending degrees.

[0040] The cable 104 is sleeved on the pipe threading line 100, and its diameter is at least greater than 50 mm and its length is at least greater than 800 mm. This design allows the cable 104 to simulate a larger cable 104 or pipe in actual use, so as to more accurately evaluate the applicability of the rail tube 102. The material of the cable 104 also needs to be selected from high-strength, wear-resistant materials to ensure that the inner wall of the rail tube 102 will not be damaged during the trial wearing process.

[0041] The wiring terminals 106 are arranged at both ends of the cable 104 and are crimped and adapted to the pipe threading wire 100. This means that the wiring terminals 106 are not only firmly connected to the cable 104, but also can form a stable connection structure with the pipe threading wire 100. This design makes it difficult for the rail pipe test device to fall off during operation, thereby improving the accuracy of the test.

[0042] In the embodiment of the utility model, the large diameter and length design of the cable 104 can more realistically simulate the cable 104 or pipeline in actual use, so as to more accurately evaluate the applicability and patency of the rail tube 102. This design avoids misjudgment caused by the large difference between the rail tube test device and the actual cable 104.

[0043] The flexibility and wear resistance of the pipe threading wire 100 enable it to be easily inserted into the rail tube 102, and the stable connection between the terminal 106 and the pipe threading wire 100 ensures stability and reliability during the trial insertion process. The operator only needs to insert the pipe threading wire 100 into the rail tube 102 and then connect the cable 104 through the terminal 106 to complete the trial insertion operation without complicated tools or equipment.

[0044] Before the formal installation of the cable 104, the use of the rail tube test device for pre-testing can timely discover and solve the possible problems of the rail tube 102, such as excessive curvature, inner wall damage, etc. This avoids the situation in which the cable 104 is damaged or the cost of replacement is increased due to problems with the rail tube 102 during the actual installation process, and also reduces the construction risk.

[0045] The rail tube test-insertion device is suitable for the test-insertion requirements of rail tubes 102 of different specifications and materials. It only needs to replace the tube-threading wires 100 and cables 104 of different diameters and lengths to adapt to different test-insertion scenarios.

[0046] According to an embodiment of the present invention, the wiring terminal 106 is provided with a guide structure for cooperating with the pipe opening of the rail tube 102 , and the wiring terminal 106 is suitable for passing through the rail tube 102 through the guide structure.

[0047] The design of the guide structure enables the terminal 106 to be more easily aligned with the tube opening of the track tube 102 and smoothly inserted. This avoids possible deviation or jamming during the trial-in process and improves the accuracy and efficiency of the trial-in. The guide structure usually has a certain degree of smoothness and wear resistance, which can reduce friction and damage to the cable 104 during the insertion process, thereby protecting the integrity and service life of the cable 104. The guide structure can be designed according to the tube openings of the track tube 102 of different specifications and shapes, so that the track tube trial-in device can be applied to a wider range of scenarios. This flexibility increases the versatility and practicality of the device.

[0048] By introducing the guide structure, the rail tube test device of the utility model further improves the technical effect on the original basis. The guide structure makes the test process smoother, reduces the difficulty and error of operation, and improves work efficiency. At the same time, it also protects the integrity of the cable 104, reducing costs and maintenance requirements.

[0049] According to an embodiment of the present invention, the guide structure includes a guide head, the guide head is arranged on a side of the wiring terminal 106 away from the cable 104, and an arc chamfer is formed on the guide head.

[0050] The guide head is arranged on the side of the terminal 106 away from the cable 104, i.e., on the side facing the pipe mouth of the rail tube 102. Such a design helps to ensure that during the trial-in process, the guide head can first contact the pipe mouth of the rail tube 102 to play a role in guiding and positioning.

[0051] The arc chamfer makes the edge of the guide head smoother, reducing the friction with the pipe opening of the rail tube 102. When the rail tube trial insertion device is pushed, the arc chamfer can penetrate the rail tube 102 more smoothly, reducing the difficulty of penetration.

[0052] The presence of the arc chamfer reduces the wear of the connecting terminal 106 and the tube mouth of the rail tube 102, especially in the case of multiple trial insertions, which can effectively protect the integrity of the rail tube 102 and extend its service life. Since the guide head has a specific shape and chamfer design, it can be more easily aligned with the tube mouth of the rail tube 102, improving the positioning accuracy during the trial insertion process.

[0053] According to an embodiment of the present invention, a scale is provided on the cable 104 .

[0054] The scale on the cable 104 allows the operator to accurately measure the length of the cable 104 inserted into the rail tube 102 during the trial insertion process. This is particularly important for application scenarios that require accurate control of the length of the cable 104, such as laying cables 104 in the fields of power, communications, etc.

[0055] By observing the scale, the operator can understand the progress of the test in real time and judge whether the cable 104 has been completely inserted into the rail tube 102 or whether it has encountered any obstacles. This helps to find problems and make adjustments in time to ensure the smooth progress of the test. The scale design allows operators to measure length and monitor progress without using additional measuring tools, thereby simplifying the operation process and improving construction efficiency.

[0056] According to an embodiment of the present invention, a marking component is further included. The marking component is arranged on the surface of the cable 104 and / or the end of the cable 104. The marking component is used to indicate the position information during the trial fitting process or display the trial fitting status.

[0057] The marking component can be set on the surface of the cable 104 to indicate a specific position during the trial insertion process by marking different colors, shapes or words. For example, different marks can be set at different lengths of the cable 104 so that the operator can quickly identify the length of the cable 104 that has been inserted into the rail tube 102.

[0058] The marking component can also be used to display the try-on status, such as by color change or light indication to indicate whether the try-on is successful, whether there is an obstacle, etc. This helps the operator to quickly judge the try-on results and take appropriate measures in time.

[0059] Through the intuitive indication of marked components, operators can understand the fitting situation more quickly and accurately, reducing the possibility of misjudgment and repeated operations, thereby improving construction efficiency.

[0060] According to an embodiment of the present invention, a pull ring 108 is further provided at one end of the connection terminal 106 away from the cable 104 ; and an anti-slip structure is provided on the pull ring 108 .

[0061] The setting of the pull ring 108 makes it convenient for the operator to hold it, and the pull ring 108 needs to have a certain structural strength to facilitate the operator to pull it. That is, after one end of the cable 104 passes through the rail tube 102, a pipe threading line 100 can be set on the pull ring 108, and the operator can pull the pipe threading line 100. When the pull ring 108 passes through the other end of the rail tube 102, the operator can directly pull the pull ring 108 to make the pipe threading line 100 pass through the rail tube 102.

[0062] By providing an anti-skid structure on the pull ring 108, the operator can avoid slipping during the pulling process. The anti-skid structure mentioned here can be an anti-skid protrusion, an anti-skid pattern, etc.

[0063] According to an embodiment of the present invention, a protective sheath is provided on the outer periphery of the cable 104 .

[0064] By providing a protective sleeve on the outer periphery of the cable 104, it is possible to prevent the outer wall of the cable 104 from scratching the inner wall of the rail tube 102. Therefore, the protective sleeve can be made of a flexible material. At the same time, it should be noted that the protective sleeve needs to be made of a material with low friction resistance to avoid large friction between the protective sleeve and the inner wall of the rail tube 102 during the pulling of the cable 104, thereby reducing the work intensity of the operator.

[0065] The second embodiment of the present invention provides a rail-crossing tube 102, comprising a tube body and the rail-crossing tube trial-insertion device as described above.

[0066] According to the rail tube 102 provided by the embodiment of the second aspect of the utility model, by setting the above-mentioned rail tube trial device, the rail tube 102 channel can be pre-tested before the rail tube 102 is installed through the built-in rail tube trial device. This can ensure that the rail tube 102 meets the relevant technical standards and safety requirements before installation, reduce the possibility of later adjustment or maintenance, and improve the quality and reliability of the project. Since the rail tube trial device has been integrated into the rail tube 102, the installer no longer needs to carry and operate the rail tube trial device separately. This greatly simplifies the installation process, shortens the installation time, and improves work efficiency. Through the pre-testing of the rail tube trial device, the installer can promptly discover and correct problems in the rail tube 102 channel, such as excessive bending, size mismatch, etc. This helps to reduce errors and rework during the installation process and reduce installation costs.

[0067] According to an embodiment of the present invention, a reserved line 110 is preset in the pipe body.

[0068] By arranging the reserved wire 110 in the pipe body, the pipe threading wire 100 can be retained in the pipe body while the pipe threading wire 100 passes through the pipe body, and the reserved wire 110 in the pipe body can be taken out.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
