Description

Technical Field

[0001] This utility model relates to the field of petroleum equipment technology, and in particular to an anti-slip adjustment device for derrick assembly and disassembly. Background Technology

[0002] Oil drilling derricks are typically 30 to 40 meters tall or more. Due to their enormous size, they are difficult to transport as a whole. Therefore, they are disassembled into parts for transport and then reassembled on-site at the well site. A derrick is generally composed of multiple sections, which are then horizontally assembled section by section at the well site. The traditional method of derrick assembly involves placing small supports under the derrick to hold it up. After installing one section, a crane lifts the derrick, and personnel or equipment must then go under the derrick to move the small supports to a new position. The crane then lowers the derrick back onto the small supports to install the next section. This process requires two or more large cranes working together, and personnel or equipment must work under the derrick being lifted by the cranes. This not only requires cranes and other equipment but also poses significant safety hazards.

[0003] In the prior art, Chinese utility model patent CN220317276U discloses "a self-propelled oil drilling derrick lifting device and its control system," which adopts a dual-lifting hydraulic structure and makes its support more stable and reliable through a reasonable force-bearing support structure layout, and has the function of adjustable support height. However, it still has the following technical problems in use: the lack of a lateral fixing device for the derrick makes it prone to lateral slippage during the lifting and lowering of the derrick.

[0004] Therefore, there is an urgent need for an anti-slip device for derrick lifting devices that can resist lateral slippage during derrick assembly and disassembly. Utility Model Content

[0028] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, the directions such as "up," "down," "left," and "right" are used in conjunction with... Figure 1 The orientation is used as a reference.

[0029] Example 1

[0030] like Figures 1 to 2 As shown, an anti-slip adjustment device for derrick assembly and disassembly includes a derrick lifting device, a derrick placement structure, and a first linear motion mechanism 1. The derrick lifting device has a lifting platform 21, and the derrick placement structure is slidably connected to the lifting platform 21 in the left-right direction. When the derrick is placed on the lifting platform 21, the derrick placement structure can limit the derrick in the left-right direction. A first mounting position is provided on the lifting platform 21, and the first linear motion mechanism 1 is fixedly installed in the first mounting position. The motion output end of the first linear motion mechanism 1 is connected to the derrick placement structure, which can drive the derrick placement structure to slide linearly in the left-right direction.

[0031] With this anti-slip device, when the derrick is placed on the lifting platform 21, the derrick placement structure can limit the derrick in the left and right directions to prevent the derrick from sliding laterally. Through the first linear motion mechanism 1, the position of the derrick placement structure can be adjusted in the left and right directions, thereby adjusting the position of the derrick in the left and right directions, which facilitates the alignment and installation of the derrick.

[0032] Preferably, the derrick placement structure and the lifting platform 21 are connected by a guide rail and a slider to form a linear sliding connection. This simplifies the structure.

[0033] Preferably, the derrick placement structure includes an anti-slip plastic plate (not shown in the figure) and a stainless steel slider 3. The stainless steel slider 3 is slidably connected to the lifting platform 21, and the anti-slip plastic plate is fixedly connected to the top of the stainless steel slider 3. The anti-slip plastic plate is used to place the derrick. The anti-slip plastic plate can provide a sufficiently large frictional force between the derrick and the anti-slip plastic plate to prevent the derrick from lateral slippage.

[0034] More preferably, the stainless steel slider has a U-shaped plate with its opening facing downwards and extending in the left-right direction. The U-shaped plate has a first baffle and a second baffle arranged opposite each other, and the first baffle and the second baffle are connected by a connecting plate to form a U-shape. The U-shaped plate is fitted downwards onto the lifting platform 21, with the inner side of the connecting plate abutting against the upper surface of the lifting platform 21, the inner side of the first baffle abutting against the front side of the lifting platform 21, and the inner side of the second baffle abutting against the rear side of the lifting platform 21. This structurally matched U-shaped plate and lifting platform 21 make the sliding connection between the derrick placement structure and the lifting platform 21 more stable.

[0035] More preferably, the anti-slip plastic sheet is made of epoxy resin.

[0036] Preferably, a third baffle (not shown in the figure) and a fourth baffle (not shown in the figure) are arranged and fixed in sequence along the left and right direction on the anti-slip plastic plate. The derrick is placed on the anti-slip plastic plate and located between the third baffle and the fourth baffle, with both the third baffle and the fourth baffle abutting against the derrick. The third baffle and the fourth baffle further prevent the derrick from sliding laterally.

[0037] Furthermore, in this embodiment, the motion output end of the first linear motion mechanism 1 moves from left to right, driving the derrick placement structure to slide linearly from left to right, and the motion output end of the first linear motion mechanism 1 moves from right to left, driving the derrick placement structure to slide linearly from right to left.

[0038] Specifically, in this embodiment, the first linear motion mechanism 1 is a hydraulic cylinder.

[0039] Specifically, the lifting device also includes a chassis frame 23, a base 24, and a crossbeam 25. The chassis frame 23 is provided with a traveling device 26 at both ends. The crossbeam 25 is mounted on the chassis frame 23 and can be raised and lowered by a first lifting hydraulic cylinder (not shown in the figure). The base 24 is located below the crossbeam 25 and is fixedly connected to the crossbeam 25 through an outer cylinder. The lifting platform 21 is mounted on the crossbeam 25 and can be raised and lowered by a second lifting hydraulic cylinder (not shown in the figure). The lifting platform 21 is provided with an inner cylinder that is slidably sleeved with the outer cylinder.

[0040] Thus, the entire structure is moved via the traveling device 26. During movement, the first lifting hydraulic cylinder extends, driving the crossbeam 25 upward. Since the crossbeam 25 and the base 24 are fixedly connected together via the outer cylinder, the base 24 rises and separates from the ground, allowing the traveling device 26 to contact the ground and thus moving the equipment. Upon reaching the designated position, the first lifting hydraulic cylinder retracts, driving the crossbeam 25 downward. Since the crossbeam 25 and the base 24 are fixedly connected together via the outer cylinder, the base 24 descends and contacts the ground until the traveling devices 26 on both sides are lifted, thus securing the equipment. After securing the equipment, the second lifting hydraulic cylinder, guided by the outer and inner cylinders, performs the lifting function for supporting the derrick.

[0041] Example 2

[0042] The main difference between this embodiment and Embodiment 1 is:

[0043] The anti-slip adjustment device for derrick assembly and disassembly also includes a second linear motion mechanism; the lifting platform 21 is also provided with a second mounting position, the first mounting position and the second mounting position are respectively located on the left and right sides of the derrick placement structure, the second linear motion mechanism is fixedly installed in the second mounting position, and the motion output end of the second linear motion mechanism is connected to the derrick placement structure; when the motion output end of the first linear motion mechanism 1 moves from left to right, and the motion output end of the second linear motion mechanism moves from left to right, the derrick placement structure slides linearly from left to right; when the motion output end of the first linear motion mechanism 1 moves from right to left, and the motion output end of the second linear motion mechanism moves from right to left, the derrick placement structure slides linearly from right to left. This further facilitates the sliding drive of the derrick placement structure.

[0044] Preferably, both the first linear motion mechanism 1 and the second linear motion mechanism are hydraulic cylinders.
