DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] As mentioned in the background art, when installing large-diameter steel pipes in water conservancy projects in the prior art, generally, the large-diameter steel pipes are lifted by hoisting, and then the position is manually adjusted repeatedly by the staff for docking. The operation is relatively cumbersome and time-consuming and laborious. The present utility model proposes a docking device for large-diameter steel pipes in water conservancy projects.

[0018] Example 1:

[0019] Please refer to Figure 1 , a butt joint device for large-diameter steel pipes used in water conservancy projects, including a base 1. Universal wheels 7 are provided at the four corners of the bottom of the base 1. The universal wheels 7 are set as universal self-locking wheels. Two lifting cylinders 2 are symmetrically arranged at the top of the base 1. A bearing plate 3 is jointly arranged at the output ends of the two lifting cylinders 2. A plurality of guide rods 9 distributed in a rectangular array are arranged at the top of the base 1. The top of the guide rod 9 penetrates through the bearing plate 3 and is slidably matched with the bearing plate 3. A support seat 4 is arranged on one side of the top of the bearing plate 3. An arc-shaped groove 5 is opened at the top of the support seat 4. The device is moved to a suitable position in the water conservancy project through the universal wheels 7 and braked, so that the support seat 4 is located directly below the installed large-diameter steel pipe. By starting the lifting cylinder 2 to drive the bearing plate 3 to lift along the guide rod 9, the arc-shaped groove 5 is fitted with the bottom of the large-diameter pipe.

[0020] In this embodiment, please refer to Figure 1 and Figure 2 , a number of equally spaced conveying components 6 are arranged on the top of the bearing plate 3 avoiding the support seat 4. The conveying component 6 includes two support plates 61. The two support plates 61 are symmetrically arranged on the top of the bearing plate 3. A conveying cylinder 63 is arranged between the two support plates 61 through a rotating shaft 62. The conveying cylinder 63 is set as a waist-drum-shaped structure with large ends and a small middle. The bearing height of the conveying cylinder 63 is the same as that of the arc-shaped groove 5. By hoisting the large-diameter steel pipe to be butted onto the conveying cylinder 63 of the conveying component 6, and pushing the large-diameter pipe to be butted to move on the conveying cylinder 63 and butt with the installed large-diameter pipe, there is no need for workers to manually adjust the position repeatedly for butt joint, the operation is relatively simple, and it saves time and effort.

[0021] Example 2:
