[0006] Preferably, the support frame includes a support beam, and mounting frames are provided at the bottom of both left and right ends of the support beam, a central axis is provided between the two mounting frames, the roller is cylindrical, and the roller is sleeved on the central axis.
[0007] Preferably, the axis of the guide wheel is arranged vertically, and wheel frames for mounting the guide wheel are provided at both left and right ends of the support frame.
[0008] Preferably, the fixed pipe clamp is fixed to the support frame by screws.
[0009] Preferably, the fixed pipe clamp is located in the middle of the top of the support frame.
[0010] Compared with the prior art, the beneficial effects of the present invention are:
[0011] The utility model utilizes the original pipeline as a shipping route support for the newly added pipeline, guide wheels are used on both sides to automatically adjust the installation direction to prevent the newly added pipeline from deviating during the installation process, cross arms are used at the ends of the installed newly added pipeline, and the support frame and the installed newly added pipeline are firmly fixed with fixed pipe clamps. The bottom of the utility model adopts a rolling method to install along the top of the original pipeline to prevent the new pipeline from falling during the installation process; while ensuring that the pipeline can be smoothly inserted into the buried pipeline trench, the soil removal and cover plate opening above the buried pipeline trench are minimized, including the workload of cover plate restoration and backfilling after the pipeline construction is completed; only local soil removal and cover plate opening are required at the weld or support bracket, which can greatly reduce the workload.

[0015] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.
[0016] Example: As attached Figure 1-2 As shown, the utility model is a special tool for pipe installation in narrow trenches, mainly to reduce the workload of on-site civil engineering excavation and backfilling. Through the utility model, the newly added pipe 5 is installed in the buried trench 7, and then excavation and the cover plate 71 are opened according to the length of the newly added pipe 5 and the position of the connection. The structure is simple and easy to operate, which can reduce the workload of civil engineering and improve construction efficiency. It includes a support frame 2 with guide wheels 1 at both ends, and the width of the support frame 2 is smaller than the width of the buried trench. The bottom of the support frame 2 is provided with a roller 3, and the roller 3 is used to roll along the original pipe 4 in the buried trench. A fixed pipe clamp 6 for fixing the newly added pipe 5 is provided on the top of the support frame 2, and the fixed pipe clamp 6 is detachably connected to the support frame 2.
