Description

Technical Field

[0001] The utility model relates to the technical field of oil drilling, in particular to a high-bracket support device for a derrick used in a square well. Background Art

[0002] For unconventional drilling in the Saudi work area, four wells are usually arranged along a straight line in a well site, with each well site 50 meters apart. After each well is drilled, the derrick base is not lowered and the drilling rig is moved horizontally as a whole. Before the construction of the first well in a new well site, it is necessary to install various drilling rig equipment at the location of the first well. After the derrick is assembled at a low position, it needs to be lifted up and placed on a high support for subsequent operations such as second-floor platform installation and drilling rope threading.

[0003] Actually in the construction process, the placement position of the high support of some drilling rig derricks is exactly at the square well position of the second well. The square well is about 7 meters long, 4 meters wide and 5 meters deep. The well wall is reinforced with iron plates around to prevent collapse. The original high support of the derrick is designed for use on a flat ground. The base design does not meet the conditions for being placed in the square well position. For this reason, the utility model provides a derrick high support support device for the square well position, which is used to assist the high support to support the derrick at the square well position.

[0029] Reference Figure 1-Figure 4 The utility model provides a high support support device for a derrick used in a square well position, comprising: a frame support platform 1 and a locking member 3. The length and width of the frame support platform 1 are both larger than the length and width of the corresponding square well, so that when the frame support platform 1 is placed in the square well position, it will not cause strong pressure on the square well position, but use the position around the square well to support the frame support platform 1. A group of support beams 105 corresponding to the longitudinal beams 201 of the high support 2 are fixedly connected to the inner side of the frame support platform 1, which are used to directly support the longitudinal beams 201 of the high support 2, so that the high support 2 is well supported in the square well position. The locking member 3 is used to lock and fix the longitudinal beams 201 and the support beams 105, so that the longitudinal beams 201 of the high support 2 are fixed together with the support beams 105, and the stability of the frame support platform 1 itself is relied on to make the high support 2 more stable as a whole, ensuring that the high support 2 is more stable and safer to use when supporting the derrick.

[0030] Specifically, the locking member 3 includes: a middle plate 301, both ends of the middle plate 301 are rotatably connected to a bracket 302, one end of the bracket 302 away from the middle plate 301 is fixedly connected to a wedge-shaped bracket foot 303, a stud 304 is fixedly connected to the top of the middle plate 301, a limiting frame 305 is sleeved on the stud 304, the limiting frame 305 corresponds to the two ends of the middle plate 301, a butterfly nut 308 is threadedly connected on the stud 304 and located above the limiting frame 305, and a guide frame 306 is fixedly connected to the bottom of the limiting frame 305, and the inner side of the guide frame 306 corresponds to the width of the bracket 302, so that it can be well stuck at the bracket 302 and slide downward.

[0031] When in use, the middle plate 301 and the brackets 302 at both ends are directly placed downward. When the wedge-shaped clamping feet 303 of the brackets 302 contact the support beam 105, they are pushed outward, causing the brackets 302 to rotate outward relative to the middle plate 301. After the wedge-shaped clamping feet 303 pass over the support beam 105, they are clamped under the support beam 105. Then the limiting frame 305 is mounted, and the butterfly nut 308 is threadedly installed, so that the limiting frame 305 is clamped on the outside of the two brackets 302, thereby limiting the outward rotation of the brackets 302, thereby achieving the purpose of fixing the longitudinal beam 201 of the high bracket 2 to the support beam 105.

[0032] In one embodiment, the frame support platform 1 is a rectangular frame, and the four corners of the frame support platform 1 are fixedly connected with lifting ears 5 to facilitate lifting the frame support platform 1.

[0033] In one embodiment, the frame support platform 1 includes: two parallel horizontal I-beams 101 and two parallel vertical I-beams 102. The two parallel horizontal I-beams 101 and the two parallel vertical I-beams 102 are fixedly connected to form a rectangular frame.

[0034] A cross structure is arranged on the inner side of the rectangular frame, and a support beam 105 is arranged longitudinally and is fixedly connected to a cross structure cross piece 103 and two parallel horizontal I-beams 101 of the cross structure. Two support beams 105 are arranged, and the two support beams 105 are respectively close to two parallel longitudinal I-beams 102.

[0035] like Figure 3As shown in the figure, three horizontal I-beams and five longitudinal I-beams are fixed by welding, wherein two parallel horizontal I-beams 101 and two parallel longitudinal I-beams 102 form a rectangular frame, and a cross-shaped structure cross-piece 103 is located inside the rectangular frame to increase strength, the cross-shaped structure includes a cross-shaped structure longitudinal piece 104 and a cross-shaped structure cross-piece 103, the cross-shaped structure longitudinal piece 104 and the cross-shaped structure cross-piece 103 are fixedly connected at the intersection, and two support beams 105 are fixedly welded near the two parallel longitudinal I-beams 102, and the support beams 105 are used to support the high bracket 2.

[0036] In one embodiment, a U-shaped clamp 4 is slidably connected to the cross-shaped structural cross member 103, corresponding to the bottom structure of the high bracket 2, and is used to assist in placing the high bracket 2; Figure 1 The U-shaped clamp 4 is located between the two connecting square tubes between the two longitudinal beams 201 of the high bracket 2.

[0037] In one embodiment, the support beam 105, the cross-shaped structural longitudinal member 104, and the cross-shaped structural transverse member 103 are all I-beams, which have very high supporting strength.
