[0026] The technical scheme of the present application is described clearly and completely below in combination with the drawings and examples. Obviously, the described examples are only some of the examples of the present application, but not all of the examples. Based on the examples in the present application, all other examples obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] Reference Figures 1 to 4 The present example proposes an auxiliary hoisting device 1 for hoisting a round pipe culvert, which comprises a first hook arm 11, a second hook arm 12 and a connecting arm 13. The first hook arm 11 and the second hook arm 12 are arranged in parallel and spaced apart. The connecting arm 13 connects the first hook arm 11 and the second hook arm 12. The first hook arm 11, the second hook arm 12 and the connecting arm 13 enclose an accommodating space 16. The first hook arm 11 is provided with a first lifting ring 14 and a second lifting ring 15. The first lifting ring 14 is fixedly installed on the first hook arm 11. The second lifting ring 15 is slidably installed on the first hook arm 11. In this way, the first hook arm 11, the second hook arm 12 and the connecting arm 13 enclose an accommodating space 16, so that the round pipe culvert 5 can be inserted and installed in the accommodating space 16, and then hoisted by a subsequent hoisting device. By selecting a hook arm instead of a steel wire rope to connect the round pipe culvert 5, the contact area with the round pipe culvert 5 is increased, and damage to the pipe of the round pipe culvert 5 is avoided. By providing the first lifting ring 14 and the second lifting ring 15 on the first hook arm 11, the relative positions of the first lifting ring 14 and the second lifting ring 15 can be adjusted by sliding the second lifting ring 15, so as to adjust the angle in the horizontal direction during hoisting of the round pipe culvert 5, facilitate splicing and butt joint with other round pipe culverts 5, and avoid problems such as deformation of the installed culvert or damage to the socket.

[0028] Specifically, the first hook arm 11 is in the shape of an I-beam in cross section, and the second lifting ring 15 is provided with a sliding groove which is connected with the first hook arm 11. By setting the first hook arm 11 in the shape of an I-beam, on the one hand, the second lifting ring 15 can slide easily, and on the other hand, the structure is compact. Of course, in this embodiment, according to actual conditions and specific needs, the cross section of the first hook arm 11 can also be set in other shapes such as T-shaped, which is not limited here.

[0029] Specifically, the auxiliary lifting device further comprises a fixing member (not shown in the figure), which can fix the second lifting ring 15 on the first hook arm 11. Specifically, the first hook arm 11 is provided with a plurality of fixing holes 110 at intervals along its length direction, and the second lifting ring 15 is provided with a through hole 150, and the fixing member passes through the through hole 150 and is connected with the fixing hole 110. In this way, when it is necessary to adjust the position of the second lifting ring 15, after sliding the second lifting ring 15 to a predetermined position, the fixing member passes through the through hole 150 and is connected with the fixing hole at different positions, so as to realize the adjustment of the position of the second lifting ring 15, which is simple and convenient.

[0030] Specifically, the fixing member is a bolt, and the fixing hole 110 is a threaded hole. Of course, in this application, the fixing member can also be a pin shaft, and the fixing hole 110 can also be a light hole, which is not limited here.

[0031] Specifically, the end surface of the first hook arm 11 is provided with a third lifting ring 17. By setting the third lifting ring 17, manual auxiliary fine adjustment of the longitudinal and transverse positions of the pipe culvert can be realized through the third lifting ring 17, so as to achieve precise butt joint effect.

[0032] In this application, during the lifting of the circular pipe culvert 5, the relative positions of the first lifting ring 14 and the second lifting ring 15 are adjusted so that the circular pipe culvert 5 is approximately balanced, and then the third lifting ring 17 is adjusted manually, so as to realize precise adjustment of the levelness of the circular pipe culvert 5.

[0033] Specifically, the first hook arm 11 is further provided with a mounting seat 18, and the first lifting ring 14 is arranged on the mounting seat 18. In this way, by setting the mounting seat 18, the stress on both ends of the first hook arm 11 is more uniform.

[0034] Specifically, the length of the second hook arm 12 is greater than the length of the first hook arm 11. In this way, the contact area with the circular pipe culvert 5 is effectively ensured, so that the second hook 12 can better bear the circular pipe culvert 5, which is beneficial to the stability of lifting.

[0035] Specifically, the first hook arm 11, the connecting arm 13 and the second hook arm 12 are integrally formed. Through the integral forming, the combination between the structures can be enhanced, the service life and durability can be enhanced, and the subsequent machining can be simplified, and the machining cost can be reduced.

[0036] In the present application, a hoisting system for round pipe culvert hoisting is also provided, please refer to Figure 4 The hoisting system includes a crane body 2, a hook 3, a connecting piece 4 and an auxiliary hoisting device 1, the hook 3 is arranged on the crane body 2, the hook 3 is connected with the auxiliary hoisting device 1 through the connecting piece 4, and the auxiliary hoisting device 1 can be connected with the round pipe culvert 5 in a plug-in manner.

[0037] Specifically, the connecting piece 4 includes a hand-operated hoist 41 and a rope 42, the first lifting ring 14 is connected with the hook 3 through a steel wire rope 43, and the second lifting ring 15 is connected with the hook 3 through the rope 42. In this way, the height of one end of the round pipe culvert 5 can be adjusted by adjusting the retraction and release of the hand-operated hoist 41, the relative position of the first lifting ring 14 and the second lifting ring 15 can be adjusted by sliding the second lifting ring 15, and the horizontal angle of the two ends of the round pipe culvert 5 can be adjusted, so that the round pipe culvert 5 can be conveniently assembled and connected with other round pipe culverts 5.

[0038] Finally, it should be pointed out that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limited, although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application.
