Description

Technical Field

[0001] This utility model relates to the field of support and guidance devices, and in particular to guide frames for pile driving platforms. Background Technology

[0002] A jacket platform, also known as a pile platform, is a platform supported by piles driven into the seabed. It can withstand external forces such as wind, waves, and currents. It can be divided into pile group type, pile foundation type (jacket type), and leg column type. The jacket platform mainly consists of four parts: jacket, piles, jacket cap, and deck. It has the advantages of strong adaptability, safety and reliability, simple structure, and low cost.

[0003] Existing guide frames generally consist of branch pipes and supports. The supports connect the four corner branch pipes together, allowing the guide frame to function as a support platform on the sea surface. Since the support platform requires a certain height, the branch pipes need to be welded layer by layer so that the combined length of the branch pipes reaches the height of the support platform. However, when existing branch pipes are spliced ​​together, there are no auxiliary guiding devices at the ends of the branch pipes to help align the upper and lower branch pipes, making the welding of the upper and lower branch pipes inconvenient. Therefore, a guide frame for pile driving platforms is needed to add guiding devices to assist in the alignment of the upper and lower branch pipes. Utility Model Content

[0004] The purpose of this utility model is to provide a guide frame for a pile driving platform to overcome the inconvenience of aligning the upper and lower branch pipes.

[0005] The technical solution to achieve the above objective is: a guide frame for a pile driving platform, including a first branch pipe and a second branch pipe, both the first branch pipe and the second branch pipe are provided with an installation mechanism, and a guide mechanism is installed on the installation mechanism;

[0006] The installation mechanism includes a connecting ring, a limiting groove, a top groove, and a bottom insertion tube. The top of the side wall of the first branch pipe and the top of the side wall of the second branch pipe are both connected to the connecting ring. The top of the connecting ring has two symmetrically distributed limiting grooves. The top of the first branch pipe and the top of the second branch pipe are both provided with top grooves.

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] Reference Appendix Figure 1-8 The guide frame for the pile driving platform includes a first branch pipe 1 and a second branch pipe 2. Both the first branch pipe 1 and the second branch pipe 2 are equipped with an installation mechanism 3, and the installation mechanism 3 is equipped with a guide mechanism 4.

[0028] The mounting mechanism 3 includes a connecting ring 301, a limiting groove 302, a top groove 303, and a bottom insertion tube 304. The top of the side wall of the first branch pipe 1 and the top of the side wall of the second branch pipe 2 are both connected to the connecting ring 301. The top of the connecting ring 301 has two symmetrically distributed limiting grooves 302. The top of the first branch pipe 1 and the top of the second branch pipe 2 are both provided with top grooves 303. The bottom end of the second branch pipe 2 is connected to the bottom insertion tube 304. The bottom of the first branch pipe 1 is connected to the bottom of the platform. The first branch pipe 1 and the second branch pipe 2 have the same structure, and the diameter of the first branch pipe 1 is equal to the diameter of the second branch pipe 2. The second branch pipe 2 is located above the first branch pipe 1. The center of the inner hole of the bottom insertion tube 304 is aligned with the center of the inner hole of the second branch pipe 2. The inner diameter of the bottom insertion tube 304 is equal to the inner diameter of the second branch pipe 2. The inner diameter of the top groove 303 is greater than the inner diameter of the second branch pipe 2. The inner diameter of the top groove 303 is equal to the outer diameter of the bottom insertion tube 304.

[0029] The first branch pipe 1 and the second branch pipe 2 have the same structure but different lengths. The second branch pipe 2 is used to extend the length of the guide frame, while the first branch pipe 1 is located at the bottom and serves as a support for the platform.

[0030] The connecting ring 301 is welded to the top of the side wall of the first branch pipe 1 and the second branch pipe 2, and the bottom insertion pipe 304 is welded to the bottom of the second branch pipe 2. The top groove 303 is opened at the top of the first branch pipe 1 and the second branch pipe 2.

[0031] Reference Appendix Figure 3-8 The guiding mechanism 4 includes a support block 401, a guide plate 402, a connecting block 403, a limiting rod 404, a through hole 405, an extension block 406, a screw hole 407, a limiting pin 408, an insertion hole 409, and a screw 410. A limiting rod 404 is inserted and connected within the limiting groove 302. The top end of the limiting rod 404 is connected to the support block 401, and the top end of the support block 401 is connected to the guide plate 402. Connecting blocks 403 are connected to both ends of the sidewall of the support block 401. Through holes 405 are formed in the sidewall of the connecting block 403. An extension block 406 is connected to the upper end of the sidewall of the connecting block 403. A screw hole 407 is formed in the sidewall of the extension block 406. A limiting pin 408 is inserted and connected within the through hole 405. The pin 408 has a hole 409 on its side wall, and a screw 410 is threadedly connected to the inner side wall of the screw hole 407. The support block 401 is semi-cylindrical in shape, and the guide plate 402 is semi-inverted frustum in shape. The inner diameter of the support block 401 is equal to the diameter of the second branch pipe 2. The upper end of the side wall of the screw 410 is threaded, and the lower end of the side wall of the screw 410 is a smooth cylindrical surface. The length of the pin 408 is greater than the sum of the widths of the two connecting blocks 403. The height of the support block 401 is equal to the distance between the top of the second branch pipe 2 and the top of the connecting ring 301, and the height of the support block 401 is equal to the distance between the top of the first branch pipe 1 and the top of the connecting ring 301.

[0032] Insert the limiting rod 404 into the limiting groove 302, so that the two support blocks 401 form a straight tube to wrap around the first branch pipe 1 or the second branch pipe 2. The two guide plates 402 form an inverted frustum-shaped guide tube. Since the height of the support block 401 is equal to the distance between the top of the second branch pipe 2 and the top of the connecting ring 301, the top of the support block 401 is flush with the top of the second branch pipe 2. Insert the limiting pin 408 into the through hole 405, so that the insertion hole 409 is aligned with the screw hole 407. Then, turn the screw 410 downward, so that the screw 410 rotates in the screw hole 407 and inserts the screw 410 into the insertion hole 409. Thus, the two support blocks 401 and the two guide plates 402 are fixed together. Simply unscrew the screw 410 and pull out the limiting pin 408 to separate and disassemble the two support blocks 401, avoiding interference with the welding of adjacent branch pipes.

[0033] When connecting the second branch pipe 2 to the first branch pipe 1, or when two adjacent second branch pipes 2 are adjacent, the bottom insertion tube 304 on the upper second branch pipe 2 is inserted into the guide tube. The inclined surface of the guide tube is used to guide the bottom insertion tube 304 and the second branch pipe 2 into the straight pipe, so that the bottom insertion tube 304 can be inserted into the top groove 303, thereby achieving the initial fixation of the second branch pipe 2, which facilitates the subsequent fixation operation of the second branch pipe 2. At the same time, the bottom end face of the upper second branch pipe 2 is in contact with the top end face of the first branch pipe 1, or the bottom end face of the upper second branch pipe 2 is in contact with the top end face of the lower second branch pipe 2, thereby achieving the effect of facilitating the alignment and contact of the two adjacent branch pipes.
