Referring to fig. 1-3, the utility model provides an auxiliary pipe penetrating trolley, which comprises a pipe wall hook 6 for being connected with the pipe wall of a pipe 11 to be penetrated and a trolley body 1 for placing a top iron 8, wherein a plurality of wheels 5 are arranged at the bottom of the trolley body 1; a longitudinal limiting piece 2 for limiting the longitudinal movement of the top iron 8 is fixed at the top of the trolley body 1; the pipe wall hook 6 is connected with the longitudinal limiting part 2 through a connecting piece 7. In practical manufacturing, four wheels 5 are preferably symmetrically arranged at the bottom of the trolley body 1 to ensure running stability.

Specifically, the longitudinal limiting part 2 is I-steel; the web of the I-steel is vertical to the top of the trolley body 1, and after the jacking iron 8 is acted by the jack 9, the front end of the jacking iron is jacked on the web of the I-steel to push the trolley to move forward.
Further, a first mounting hole 201 is formed in the longitudinal limiting member 2; the connecting piece 7 is connected with the longitudinal limiting piece 2 through the first mounting hole 201.
In a refined embodiment, as shown in fig. 4, the pipe wall hook 6 may be made of steel plate, and an inserting slot 601 matched with the pipe wall thickness of the pipe 11 to be penetrated is formed on one side. When in use, the pipe wall is inserted into the slot 601, so as to realize the connection of the trolley and the pipeline 11. Further, a second mounting hole 602 is formed in the pipe wall hook 6; the connecting piece 7 is connected with the pipe wall hook 6 through the second mounting hole 602.
In order to facilitate the transfer of the auxiliary tube penetrating trolley, a hook 4 is arranged at a proper position of the trolley body 1, such as the tail of the trolley. After the current pipe joint passes, the lower joint pipeline is welded, the external towing equipment is connected with the trolley through the hook, the trolley is towed to move to the lower joint pipeline, the hydraulic oil cylinder collision damage in the installation process is avoided, the repeated installation is avoided, and the pipe penetrating efficiency is greatly improved.
