DETAILED DESCRIPTION

[0022] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example 1, by Figures 1-2 The present invention relates to a dynamic load pipe clamp for axial positioning of a riser, including a lower pipe clamp 1, an upper pipe clamp 3 above the lower pipe clamp 1, a connecting mechanism 2 between the lower pipe clamp 1 and the upper pipe clamp 3, and rubber pads 5 fixedly connected to the inner walls of both the lower pipe clamp 1 and the upper pipe clamp 3. The rubber pads 5 are used to increase the friction between the lower pipe clamp 1 and the upper pipe clamp 3 and the pipe.

[0024] Specifically, by Figures 2-5 The connecting mechanism 2 includes a movable plate 201 located below the lower pipe clamp 1. Two side shafts 207 are symmetrically rotatably connected to the outer side of the upper pipe clamp 3. A side block 204 is fixedly connected to the end of each side shaft 207 away from the upper pipe clamp 3. Both side blocks 204 are located below the movable plate 201. Limiting rods 2012 are fixedly connected to the top of each side block 204. Two uprights 206 are symmetrically fixedly connected to the bottom of the lower pipe clamp 1. Limiting blocks 2011 are fixedly connected to the bottom ends of each upright. The movable plate 201 is movably sleeved on the outer side of the two uprights 206. The two side blocks 204 abut against the two uprights 206 respectively. Positioning pins 4 are fixedly connected to the top of the lower pipe clamp 1 near the four corners. The upper pipe clamp 3 is movably sleeved on the outside of each positioning post 4. The bottom of the lower pipe clamp 1 is provided with a receiving groove 6. A threaded rod 208 is fixedly connected inside the receiving groove 6. A threaded cylinder 202 is threadedly sleeved on the outside of the threaded rod 208. The outer diameter of the threaded cylinder 202 is equal to the inner diameter of the receiving groove 6. The top of the threaded cylinder 202 is located inside the receiving groove 6 to shield and protect the threaded rod 208, thereby preventing the threaded rod 208 from being exposed and corroded. A turntable 205 is fixedly connected to the bottom of the threaded cylinder 202. A movable plate 201 is sleeved on the outside of the threaded cylinder 202 and does not contact the threaded cylinder 202. An outer ring 203 is fixedly sleeved on the outside of the threaded cylinder 202. The outer ring 203 is located above the movable plate 201.

[0025] In use, first place the lower pipe clamp 1 on the outside of the pipe, then place the upper pipe clamp 3 on the outside of the pipe and fit it around the outside of each positioning post 4. Then rotate the two side shafts 207 to drive the two side blocks 204 to move until the two side blocks 204 abut against the two posts 206 respectively. At this time, the two side blocks 204 are both located below the movable plate 201. Then rotate the turntable 205 to drive the threaded cylinder 202 to rotate outside the threaded rod 208. At the same time, the threaded cylinder 202 moves downward and drives the outer ring 203 to move downward. Then push the movable plate 201 downward so that it slides down along the two posts 206, so that the movable plate 201 fits on the outside of the two limiting rods 2012 and abuts against the two side blocks 204. Then continue to move the movable plate 201 downward to push the two side blocks 204. Drive the upper pipe clamp 3 to move through the two side shafts 207. Finally, connect and fix the lower pipe clamp 1 and the upper pipe clamp 3 to clamp the pipe, realizing the rapid limiting and fixing of the pipe.

[0026] Specifically, by Figure 5 As shown, multiple top posts 2010 are fixedly connected at equal angles to the top of the movable plate 201. Each top post 2010 is provided with a ball bearing 209 at its top end, and each ball bearing 209 abuts against the bottom of the outer ring 203.

[0027] In use, multiple top posts 2010 and ball bearings 209 are set between the movable plate 201 and the outer ring 203 to avoid direct contact between the movable plate 201 and the outer ring 203, reduce the friction between the outer ring 203 and the movable plate 201, thereby facilitating the rotation and movement of the outer ring 203 and enabling it to quickly push the movable plate 201.
