Description

Technical Field

[0001] This utility model relates to the field of oil drilling and repair equipment, and in particular to a detachable power catwalk and site pipe laying mechanism. Background Technology

[0002] Catwalks and pipe racks are peripheral supporting equipment used for retrieving and storing pipes during drilling and workover operations. Due to the different heights of the workover platform required for different well locations, the drill pipe rack needs to be frequently disassembled and reassembled before use to adapt to well locations of different heights. The pipe racks are very heavy, and connecting them to the catwalks requires the cooperation of cranes and workers. The disassembly and installation process is quite cumbersome, time-consuming, labor-intensive, and inefficient. Utility Model Content

[0003] To address the problem of low assembly and disassembly efficiency of traditional catwalks and pipe racks, this invention provides a detachable powered catwalk and site pipe rack mechanism.

[0004] The technical solution provided by this utility model is: a detachable power catwalk and site pipe laying mechanism, including a catwalk and a pipe laying frame. The pipe laying frame includes a section of channel steel with the vertical ribs of the channel steel facing downwards. Two single columns are welded to the lower part of the vertical ribs of the channel steel. The single columns are located on both sides of the channel steel. A herringbone column is welded to the lower part of the single column, and a base plate is welded to the lower part of the herringbone column. A hoisting assembly is installed on the pipe laying frame. The hoisting assembly includes a hoisting arm, which is U-shaped. A disc is welded to one end of the hoisting arm, and a torsion tube is welded to the disc. The torsion tube passes horizontally through one single column. After the torsion tube passes through the single column, a torsion spring and a washer are fitted on it. A cotter pin is installed on the outside of the washer on the torsion tube. One end of the torsion spring is inserted into the torsion tube, and the other end is inserted into the single column. The connection structure between the other end of the hoisting arm and another single column is as described above. The axes of the two torsion tubes are concentric.

[0005] The lifting arm extends to the outside of the channel steel, which has a notch at the lifting arm position. The notch allows the lifting arm to rotate around the torsion tube to an upright or horizontal position. A lifting ring is welded to the center of the lifting arm, and the lifting ring is arranged horizontally when the lifting arm is in a horizontal position.

[0006] The channel steel and the cover plate are connected by a positioning sleeve and a positioning post. The positioning sleeve is welded to the cover plate, and the positioning post is welded to the channel steel. The inner hole of the positioning sleeve is larger than that of the positioning post. The upper end of the inner hole of the positioning sleeve has a conical hole, and the bottom of the positioning post is machined into a conical head structure.

[0007] Both the single column and the support column are equipped with a lifting mechanism. The lifting mechanism has the same structure. The following explanation is based on the single column: The single column is cut into two sections in the middle. A nut is welded into each section of the single column. The spiral directions of the two nuts are opposite. The two nuts are connected by threads to a double-ended bolt. A torque hole is opened in the middle of the double-ended bolt.

[0008] A permanent magnet ring is inlaid in the upper part of the conical hole, and the inner hole of the permanent magnet ring is the same size as the conical hole.

[0009] The torsion spring is released in the direction that the lifting arm is in a horizontal position.

[0010] The beneficial effects of this utility model are as follows: Each pipe rack is equipped with a dedicated lifting component. During normal use, the lifting arm is in a horizontal state and does not occupy the pipe rack space. When the pipe rack and catwalk need to be installed or dismantled, the lifting arm can be lifted by inserting the hook into the hole of the lifting ring from one side, thereby lifting the pipe rack. No manual assistance is required during the lifting process, reducing labor costs. After the pipe rack is lifted into place, the hook is lowered. After the pipe rack is on the ground, the lifting arm and lifting ring are in a horizontal state. The hook can be disengaged from the lifting ring by continuing to lower. Attached Figure Description

Detailed Implementation

[0019] like Figures 1-7As shown, a detachable powered catwalk and site pipe laying mechanism includes a catwalk 2 and a pipe laying frame 1. The pipe laying frame 1 includes a section of channel steel 101 with the vertical ribs of the channel steel 101 facing downwards. Two single columns 102 are welded to the lower part of the vertical ribs of the channel steel 101, located on both sides of the channel steel 101. A-frame columns 103 are welded to the lower part of the single columns 102, and base plates 104 are welded to the lower part of the A-frame columns 103, allowing the pipe laying frame 1 to stand independently. A lifting assembly 5 is installed on the pipe laying frame 1, including a lifting arm 501. 1. The lifting arm 501 is U-shaped. A disc 502 is welded to one end of the lifting arm 501. A torsion tube 503 is welded to the disc 502. The torsion tube 503 passes laterally through a single column 102. After passing through the single column 102, the torsion tube 503 is fitted with a torsion spring 6 and a washer 504. A cotter pin 7 is installed on the outside of the washer 504 on the torsion tube 503. One end of the torsion spring 6 is inserted into the torsion tube 503 and the other end is inserted into the single column 102. The other end of the lifting arm 501 is connected to another single column 102 as described above. The axes of the two torsion tubes 503 are concentric.

[0020] The lifting arm 501 extends to the outside of the channel steel 101. The channel steel 101 has a notch 105 at the position of the lifting arm 501. The notch 105 allows the lifting arm 501 to rotate around the torsion tube 503 to an upright or horizontal state. A lifting ring 505 is welded to the center of the lifting arm 501. The lifting ring 505 is arranged horizontally when the lifting arm 501 is in a horizontal state.

[0021] Each pipe rack 1 is equipped with a dedicated lifting assembly 5. Under normal use, the lifting arm 501 is in a horizontal position and does not occupy the pipe rack space. When the pipe rack 1 and cat walkway 2 need to be installed or dismantled, the lifting hook is inserted into the hole of the lifting ring 505 from one side to lift the lifting arm 501, thereby lifting the pipe rack 1. No manual assistance is required during the lifting process, reducing labor costs. After the pipe rack 1 is lifted into place, the lifting hook is lowered. After the pipe rack 1 is on the ground, the lifting arm 501 and the lifting ring 505 are in a horizontal position. The hook can be disengaged from the lifting ring 505 by continuing to lower.

[0022] The channel steel 101 and the cover plate 201 are connected by the positioning sleeve 3 and the positioning post 4. The positioning sleeve 3 is welded to the cover plate 201, and the positioning post 4 is welded to the channel steel 101. The inner hole of the positioning sleeve 3 is larger than that of the positioning post 4. A conical hole 301 is opened at the upper end of the inner hole of the positioning sleeve 3. The bottom of the positioning post 4 is machined into a conical head 401 structure to reduce the alignment accuracy during connection. The positioning post 4 of the pipe rack 1 is moved to the upper part of the positioning sleeve 3 by a crane, and the connection is completed by lowering the pipe rack 1.

[0023] Both the single column 102 and the support column 202 are equipped with a lifting mechanism. The lifting mechanism has the same structure. The following description takes the single column 102 as an example: The single column 102 is cut into two sections in the middle. A nut 9 is welded into each section of the single column 102. The spiral directions of the two nuts 9 are opposite. The two nuts 9 are threadedly connected to a double-ended bolt 8. A torque hole 801 is opened in the middle of the double-ended bolt 8. The height can be adjusted by inserting a tool into the torque hole 801 and rotating the double-ended bolt 8.

[0024] A permanent magnet ring 302 is embedded in the upper part of the conical hole 301. The inner hole of the permanent magnet ring 302 is the same size as that of the conical hole 301. The permanent magnet ring 302 magnetically attracts the positioning post 4 near it, further reducing the alignment accuracy during installation.

[0025] The release direction of the torsion spring 6 is: the lifting arm 501 is in a horizontal state.
