[0006] To solve the above technical problems, the utility model provides a pipe rolling mechanism for cast pipe transportation, which comprises a handle and a clamping jaw arranged at the end of the handle.

[0007] Further, the width of the socket is 1.3-1.4 times the thickness of the steel pipe wall.

[0008] Further, the upper clamping column and the lower clamping column are arranged in parallel and form an included angle of 90-120° with the handle holding part, and the length of the upper clamping column and the lower clamping column is 80-100 mm.

[0009] Further, the upper clamping column and the lower clamping column are welded on the side wall of the handle.

[0010] Further, the handle is made of steel pipe, and the steel pipe end is provided with through holes for the upper clamping column and the lower clamping column to pass through, and the upper clamping column and the lower clamping column are welded on the steel pipe near the through holes on both sides. Further, the handle is made of steel pipe, and the steel pipe end is provided with through holes for the upper clamping column and the lower clamping column to pass through, and the upper clamping column and the lower clamping column are welded on the steel pipe near the through holes on both sides.

[0011] Furthermore, the handle is formed by welding an upper steel pipe and a lower steel pipe together, with the upper steel pipe and the lower steel pipe forming an angle of 25°-45°.

[0012] Furthermore, the upper and lower locking posts are made of steel bars or reinforcing bars with a diameter of 12-16mm.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model discloses a rolling mechanism for transporting cast iron pipes. By setting a chuck at the socket of the cast iron pipe, the chuck uses the locking slot on the chuck to lock the cast iron pipe into place. The handle on the chuck acts as an extended lever arm, making it easy and convenient to drive the cast iron pipe to roll on the track. This avoids direct contact between people and the pipe body, greatly reducing safety risks and labor intensity. Attached Figure Description

[0020] 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.

[0021] like Figures 1-4 This is a schematic diagram of a rolling mechanism for transporting cast iron pipes proposed in this utility model. The rolling mechanism for transporting cast iron pipes includes a handle 3 and a pawl disposed at the end of the handle. The pawl includes an upper pawl 4 and a lower pawl 5, and a pawl 6 for engaging with the casting pipe socket is provided between the upper pawl 4 and the lower pawl 5.

[0022] In this embodiment, a clamp is provided at the socket of the cast pipe 1. The clamp is used to engage the cast pipe socket. The handle on the clamp acts as an extended lever arm, making it easy to drive the cast pipe to roll on the track. This avoids direct contact between people and the pipe body, greatly reducing safety risks and labor intensity.

[0023] In a preferred embodiment, the width of the bayonet 6 is set to 1.3-1.4 times the thickness of the steel pipe wall.

[0024] In a preferred embodiment, the upper locking post 4 and the lower locking post 5 are arranged in parallel and form an angle of 90°-120° with the hand-held part of the handle 3. The length of the upper locking post and the lower locking post is set to 80-100mm. This structure in this embodiment is convenient to operate and keeps the hand away from the end of the steel pipe.
