DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model. Apparently, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] As shown in Figure 1 , the utility model is an offshore pile sleeve construction auxiliary equipment, and the structure mainly comprises an auxiliary frame 1 and a stability mechanism 2.

[0022] The auxiliary frame 1 is used for installing and fixing the stability mechanism 2, the middle part of the auxiliary frame 1 is a passing port 1-1, the passing port 1-1 is used for the passing of the pile sleeve, a plurality of stability mechanisms 2 are distributed around the passing port 1-1 center through the passing port 1-1, the pile sleeve passing the passing port 1-1 of the auxiliary frame 1 is stably clamped through the multiple stability mechanisms 2, so that the stability of the pile sleeve during the installation process is ensured.

[0023] As shown in Figure 1 ,Figure 2 as well as Figure 3 As shown, the stabilizing mechanism 2 includes a stabilizing frame 3, an upper balancing frame 4, a lower balancing frame 5, upper rollers 7 and 8, and a synchronization frame 6. The stabilizing frame 3 is vertical and connected to the auxiliary frame 1. The upper balancing frame 4 is hinged to the upper part of the stabilizing frame 3, and the lower balancing frame 5 is hinged to the lower part of the stabilizing frame 3. Both the upper balancing frame 4 and the lower balancing frame 5 are rod-shaped structures, and both are located on the inner side of the stabilizing frame 3.

[0024] An upper roller 7 is provided at the end of the upper balance frame 4, and a lower roller 8 is provided at the end of the lower balance frame 5. Both the upper roller 7 and the lower roller 8 can rotate around a horizontal axis. When the pile foundation sleeve passes through, the upper roller 7 and the lower roller 8 contact the surface of the pile foundation sleeve. Multiple sets of upper rollers 7 and lower rollers 8 together clamp the pile foundation sleeve, allowing the pile foundation sleeve to move up and down along the axial direction.

[0025] A synchronization frame 6 is provided between the upper balance frame 4 and the lower balance frame 5. The upper end of the synchronization frame 6 is hinged to the upper balance frame 4, and the lower end of the synchronization frame 6 is hinged to the lower balance frame 5. The synchronization frame 6 enables the upper balance frame 4 and the lower balance frame 5 to swing up and down synchronously, thereby adjusting the positions of the upper roller 7 and the lower roller 8 at the same time.

[0026] A telescopic mechanism is provided between the lower balance frame 5 and the stabilizer frame 3. The telescopic mechanism controls the swing angle of the lower balance frame 5, thereby synchronously controlling the positions of the upper roller 7 and the lower roller 8.

[0027] Furthermore, such as Figures 1-4 As shown, the telescopic mechanism includes a force-bearing column 10 and a hydraulic cylinder 9. One end of the hydraulic cylinder 9 is hinged to the stabilizer 3, and the other end is provided with a sliding sleeve 11. One end of the force-bearing column 10 is hinged to the lower balance frame 5, and the other end is located inside the sliding sleeve 11 and is slidably connected to the sliding sleeve 11. A spring 12 is provided inside the sliding sleeve 11, and the two ends of the spring 12 are in contact with the bottom surface of the sliding sleeve 11 and the end face of the force-bearing column 10, respectively.

[0028] The load-bearing column 10 can slide within the sliding sleeve 11. Through the elastic action of the spring 12, the load-bearing column 10 can adaptably expand and contract within a certain range along its own axis when subjected to external force, thereby forming a flexible connection between the pile foundation sleeve and this utility model. During the installation process, the pile foundation sleeve can be buffered. Since rigid connection is avoided, damage to the pile foundation sleeve can be effectively prevented.

[0029] Among them, an anti-detachment structure is provided at the end of the force-bearing column 10, specifically a disc-shaped structure with a diameter larger than that of the force-bearing column 10 body, which can prevent the end of the force-bearing column 10 from detaching from the sliding sleeve 11.

[0030] The stable frame 3, the synchronous frame 6, the upper balance frame 4 and the lower balance frame 5 form a parallelogram structure. The stable frame 3, the upper balance frame 4, the synchronous frame 6 and the lower balance frame 5 arranged in a parallelogram can keep the upper balance frame 4 and the lower balance frame 5 always parallel to each other when the angle of the upper balance frame 4 or the lower balance frame 5 changes, and the positions of the upper roller 7 and the lower roller 8 can also keep vertical.

[0031] Further, the shape of the lower balance frame 5 and the lower roller 8 is the same as that of the upper balance frame 4 and the upper roller 7.

[0032] As a further improvement of the offshore pile sleeve construction auxiliary equipment, the stable mechanism 2 is arranged below the auxiliary frame 1, and the stable mechanism 2 is at least three, and the stable mechanism 2 is uniformly distributed around the center of the through port 1-1, and the multiple stable mechanisms 2 can stably clamp the pile sleeve.

[0033] In an embodiment of the utility model, the auxiliary frame 1 main body is rectangular frame structure, and the through port 1-1 is rectangle. At this time, the stable mechanism 2 is four, and the four stable mechanisms 2 are respectively located in the middle of the four edges of the rectangular auxiliary frame 1.

[0034] Further, the upper part of the auxiliary frame 1 is provided with the connecting frame 1-2, and the auxiliary frame 1 is fixedly connected with the surrounding structure through the connecting frame 1-2.

[0035] The working principle and use process of the utility model: when needing to install the pile sleeve, the pile sleeve one end can be lifted by crane, then the lower end of the pile sleeve can be inserted into the through port 1-1 of the auxiliary frame 1, at this time, the upper roller 7 at the end of the upper balance frame 4 will first be connected with the surface of the sleeve, while being connected, the upper balance frame 4 will transmit power to the lower balance frame 5 through the synchronous frame 6, and the lower balance frame 5 will drive the sliding between the stress column 10 and the hydraulic cylinder 9 and compress the spring 12 in the sliding sleeve 11, thereby buffering the contact between the pile sleeve and the upper roller 7, as the pile sleeve gradually descends, the upper roller 7 rotates, and the lower roller 8 and the pile sleeve also contact and rotate, as the pile sleeve continues to descend, the upper roller 7 and the lower roller 8 will roll with the surface of the pile sleeve, then the pile sleeve can be installed under the stability of the stable mechanism 2.

[0036] When the diameter of the pile sleeve to be installed changes, the hydraulic cylinder 9 can be controlled to extend and retract, and the stress column 10 will also drive the lower balance frame 5 to swing under the length change of the hydraulic cylinder 9, and at this time, the position of the upper balance frame 4 and the upper roller 7 will also change, thereby enabling the device to assist in installing sleeves of different diameters.

[0037] Finally, it should be noted that: the above is only the preferred embodiment of the utility model, and is not used to limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or make equivalent replacement to part of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
