Description

Technical Field

[0001] The utility model relates to the field of drilling rigs, in particular to an assembled drilling rig tower. Background Art

[0002] The drilling rig tower, also known as the drilling tower, is an important part of the drilling equipment. It is a metal truss with a certain height and span. The drilling rig tower provides an installation location for the lifting system, allowing the drilling equipment to be lifted and moved smoothly.

[0003] Currently, the tower is too long, which makes it inconvenient to transport; some assembled towers have large bases and heavy weight, which makes the installation and disassembly process relatively inconvenient; at the same time, after the assembled tower is bolted, the connection is only bolted without more insertion and docking mechanisms, and the overall structural stability is slightly low. Utility Model Content

[0004] The utility model aims to provide an assembled drilling rig tower which is combinable and has a stable structure.

[0005] The purpose of the utility model is achieved as follows: an assembled drilling rig tower, comprising a bottom fixing plate, a top fixing plate, and four groups of support frames arranged between the bottom fixing plate and the top fixing plate, the support frames are provided with transverse reinforcing ribs, vertical reinforcing ribs and diagonal reinforcing ribs; the support frames, transverse reinforcing ribs, vertical reinforcing ribs and diagonal reinforcing ribs are all hollow structures; through holes are provided at the connection between the bottom fixing plate, the top fixing plate and the support frames, which are connected to the ports of the support frames; an enlarged fixing step is machined in the through hole of the bottom fixing plate, and an annular reinforcing rib is provided on the periphery of the through hole of the top fixing plate; an internal thread is provided in the through hole at the connection between the bottom fixing plate and the support frame, and a docking column is rotatably connected in the through hole.

[0006] Preferably, a channel is provided in the center of the bottom fixing plate and the top fixing plate, and a plurality of groups of fixing through holes are evenly provided around the channel. The sizes of the bottom fixing plate and the top fixing plate and the positions of the fixing through holes are kept consistent.

[0007] Preferably, the diameter of the docking column is smaller than the inner diameter of the through hole, and the outer diameter of the annular reinforcing rib is smaller than the inner diameter of the enlarged fixing step.

[0008] Preferably, one end of the docking column is provided with an external thread for rotationally fixing with a through hole of the top fixing plate.

[0009] Preferably, triangular reinforcement plates are provided between the transverse reinforcement ribs and the support frame, and between the support frame and the bottom fixing plate and the top fixing plate.

[0010] Preferably, a hollow reinforcement plate is provided between the support frames and close to one side of the bottom fixing plate or the top fixing plate.

[0011] Preferably, the support frame is provided with a water outlet at one end close to the bottom fixing plate or the top fixing plate.

[0012] Compared with the prior art, the utility model is beneficial in that:

[0013] 1. The support frame and reinforcement ribs are set as hollow structures, which greatly reduces the overall weight and facilitates the lifting of the drilling rig by the hydraulic cylinder. At the same time, the position of the reinforcement ribs is optimized to ensure the stability of the overall structure;

[0014] 2. The docking column is arranged to dock with the through hole of another set of bottom fixing plates. When the bolts are loosened, the docking column can contact with the inner wall of the through hole to avoid a large tilt angle and improve safety;

DETAILED DESCRIPTION

[0023] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0024] It should be noted that in the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the utility model product is usually placed when in use, which are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. Terms such as "horizontal", "vertical", and "overhanging" do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0025] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] like Figure 1-5 As shown, an assembled drilling rig tower comprises a bottom fixing plate 1, a top fixing plate 2, and four groups of support frames 3 arranged between the bottom fixing plate 1 and the top fixing plate 2. The support frames 3 are provided with transverse reinforcing ribs 4, vertical reinforcing ribs 5 and diagonal reinforcing ribs 6, and the multiple reinforcing ribs are all for improving the overall structural strength; the support frames 3, the transverse reinforcing ribs 4, the vertical reinforcing ribs 5 and the diagonal reinforcing ribs 6 are all hollow structures, which further reduce the overall gravity; a through hole 7 is provided at the connection between the bottom fixing plate 1, the top fixing plate 2 and the support frame 3, which is connected to the port of the support frame 3; an enlarged fixing step 701 is machined in the through hole 7 of the bottom fixing plate 1, and an annular reinforcing rib 8 is provided on the periphery of the through hole of the top fixing plate 2; an internal thread is provided in the through hole at the connection between the bottom fixing plate 1 and the support frame 3, and a docking column 9 is rotatably connected in the through hole 7.

[0027] like Figure 1-2 As shown, a channel 10 is provided in the center of the bottom fixing plate 1 and the top fixing plate 2, and a plurality of fixing through holes 11 are evenly provided around the channel 10. The sizes of the bottom fixing plate 1 and the top fixing plate 2 and the positions of the fixing through holes are consistent. The through holes on the bottom fixing plate and the top fixing plate can correspond one to one after the docking of the docking column 11, so that the two can be fixed by bolts later.

[0028] like Figure 3-4 As shown, the diameter of the docking column 9 is smaller than the inner diameter of the through hole 7, and the outer diameter of the annular reinforcement rib 8 is smaller than the inner diameter of the enlarged fixing step 701, ensuring that the docking column protrusion located on one side of the top fixing plate can be inserted into the through hole in the bottom fixing plate of another group.

[0029] like Figure 3 As shown, one end of the docking post 9 is provided with an external thread which is rotatably fixed to the through hole of the top fixing plate 2, and the other end of the docking post is unthreaded to reduce the number of turning steps and reduce the cost of use; at the same time, the length of the thread and the smooth cylindrical surface can also be limited to avoid the problem of the thread being screwed in too much, which will cause the exposed length of the docking post to be too short.

[0030] like Figure 1-2 As shown, triangular reinforcing plates 14 are provided between the transverse reinforcing ribs 4 and the support frame 3, and between the support frame 3 and the bottom fixing plate 1, and the top fixing plate 2, to improve the stability of the connecting piece and avoid falling off and cracking after long-term use.

[0031] like Figure 1-2 As shown, a hollow reinforcement plate 12 is provided between the support frames 3 and on one side of the bottom fixing plate 1 or the top fixing plate 2. The hollow reinforcement plate can greatly enhance the stability between the end of the support frame and the bottom fixing plate or the top fixing plate to avoid looseness between the two.

[0032] like Figure 1-5 As shown, a water outlet 13 is provided at one end of the support frame 3 close to the bottom fixing plate 1 or the top fixing plate 2. When it rains, rainwater will enter from the top port of the support frame. The provided water outlet can effectively discharge the rainwater to avoid internal rainwater accumulation.

[0033] The working principle of the utility model is explained as follows: the triangular reinforcement plate, transverse reinforcement ribs, vertical reinforcement ribs and diagonal reinforcement ribs are all used to ensure the stability of the overall structure. The hollow reinforcement plate is mainly used to strengthen the structural stability of the end of the support frame. The more stable the end of the support frame, the more stable the support frame as a whole. After the two sets of tower frames are docked, one end of the docking column is screwed into the top fixing plate and the other end is inserted into the bottom fixing plate. When some bolts are loosened, the docking column will conflict with the inner wall of the support frame to avoid large-angle shaking, thereby improving safety and stability.

[0034] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary personnel in the field to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents of the present invention for protection have been fully recorded in the claims.
