Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] Please see Figure 1 , Figure 2 and Figure 6 The present invention provides a steel welded traction head, comprising a cone tube 1, which is hollow inside with an open bottom. The top of the cone tube 1 is connected to a traction ear plate 2, and the traction ear plate 2 is provided with a traction hole 3. The bottom of the cone tube 1 is connected to a connecting pipe 4.

[0033] A reinforcing plate 5 is fixedly installed on the inner wall of the tapered tube 1. The reinforcing plate 5 is cross-shaped.

[0034] The cone tube 1 is welded to the traction ear plate 2 and the connecting tube 4.

[0035] Steel pipe 6 is welded to the bottom of connecting pipe 4.

[0036] Working principle: In actual construction, a connecting pipe 4 of the appropriate specification is selected according to the diameter of the towing steel pipe 6, and the connecting pipe 4 is welded to the bottom of the cone pipe 1. A traction ear plate 2 of the appropriate specification is selected according to the pulling force of the towing equipment, and the traction ear plate 2 is welded to the top of the cone pipe 1. Then, the steel pipe 6 is welded to the connecting pipe 4. After that, the hook of the towing equipment is passed through the traction hole 3 on the traction ear plate 2 to establish a connection with the towing traction head. At this time, the pulling force generated by the towing equipment is transmitted to the traction ear plate 2 through the traction hole 3. The pulling force is transmitted from the traction ear plate 2 to the cone pipe 1, and then transmitted to the steel pipe 6 welded at the bottom through the connecting pipe 4. In this process, the stable structure ensures the effective transmission of the pulling force, thereby driving the steel pipe 6 to move and completing the tasks of towing and laying pipes in trenchless pipeline construction.

[0037] Example 2

[0038] Please see Figure 3 , Figure 4 , Figure 5 and Figure 6 The present invention provides a steel welded traction head, comprising a cone tube 1, which is hollow inside with an open bottom. The top of the cone tube 1 is connected to a traction ear plate 2, and the traction ear plate 2 is provided with a traction hole 3. The bottom of the cone tube 1 is connected to a connecting pipe 4.

[0039] A reinforcing plate 5 is fixedly installed on the inner wall of the tapered tube 1. The reinforcing plate 5 is cross-shaped.

[0040] The cone tube 1 is welded to the traction ear plate 2 and the connecting tube 4.

[0041] The side wall of the connecting pipe 4 is provided with a connecting threaded hole 7, which is used to connect and fix the PE pipe or ductile iron pipe 9 with the connecting bolt 8.

[0042] The inner diameter of the connecting pipe 4 matches the outer diameter of the PE pipe or ductile iron pipe 9.

[0043] There are two sets of threaded holes 7 symmetrically arranged around the center line of the longitudinal axis of the connecting pipe 4, and each set of threaded holes 7 has two holes arranged symmetrically from top to bottom.

[0044] Working principle: In actual construction, the corresponding specification of the connecting pipe 4 is selected according to the diameter of the PE pipe or ductile iron pipe 9. The connecting pipe 4 is welded to the bottom of the tapered pipe 1. The corresponding specification of the traction ear plate 2 is selected according to the pulling force of the towing equipment. The traction ear plate 2 is welded to the top of the tapered pipe 1. Then, the connecting bolt 8 is threaded into the connecting threaded hole 7. The PE pipe or ductile iron pipe 9 is connected to the connecting pipe 4 through the connecting bolt 8. The towing equipment applies the pulling force through the traction hole 3. The pulling force is transmitted to the connecting pipe 4 through the traction ear plate 2 and the tapered pipe 1 in sequence. Since the connection between the pipe and the connecting pipe 4 is stable, the connecting pipe 4 can reliably drive the PE pipe or ductile iron pipe 9 to move, completing the tasks of towing and laying pipes in trenchless pipeline construction.
