[0002] The height of an oil drilling derrick generally reaches more than thirty or forty meters. Due to its huge volume, it is not easy to transport as a whole. Therefore, during use, it is disassembled into loose parts for transportation and then assembled on-site at the well site. The derrick is generally composed of multiple sections. The traditional assembly method is to cooperate two cranes and forklifts to complete the assembly of each section in sequence from bottom to top. This method has a high safety risk, is very easy to cause personal injuries, and is also easy to cause damage to components.

[0003] Chinese Utility Model Patent CN220317276 U discloses a remote-controlled self-propelled crawler roller type oil drilling derrick disassembly, assembly and lifting device and its control system. It adopts a double-lifting hydraulic structure and through a reasonable layout of the force-bearing support structure, its support is more stable and reliable, and it has the function of adjustable support height. The following technical problems exist in its use process: 1) When it is working, it only relies on the base to support the equipment, and the support span of its outer cylinder is limited. Due to the poor working environment at the construction site, the overall equipment is very unstable; 2) During the process of the derrick being jacked up, the movement mode of the derrick is rotation with the end close to the oil well as the axis. The equipment relies on the cross beam to jack up the derrick. When lifting the derrick, as the derrick is lifted, relative movement will occur between the derrick and the cross beam, which is easy to cause damage to the derrick or the cross beam.

Specific embodiments

[0024] The following further describes the present utility model with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here in conjunction with the accompanying drawings is for better explanation. The structure of the present utility model necessarily goes beyond these limited embodiments, and for some equivalent replacement schemes or common means, no detailed description will be given herein, but they still fall within the protection scope of this application.

[0025] Figures 1 to 6 is the best embodiment of the present utility model. The following further describes the present utility model in conjunction with the attached Figures 1 to 6 drawings.

[0026] Refer to the attached Figures 1 - 6, a remote-controlled self-propelled crawler roller type oil drilling derrick disassembly, installation and lifting device, comprising a base, a traveling device 8, a main lifting device, a supporting bracket 1 and a guiding device. Among them, the base includes a first base 12 and a second base 13. There are two second bases 13 arranged on both sides of the first base 12. A guiding device is arranged on the upper side of each second base 13. The supporting bracket 1 is arranged between the guiding devices on both sides. The main lifting device is installed on the first base 12. The main lifting device is connected to the supporting bracket 1 and drives it to lift and lower. There are two traveling devices 8 arranged on both sides of the guiding device. A lifting device 5 is arranged between each traveling device 8 and the guiding device. The lifting devices separate the bases at intervals, and each base can adapt to the environment around the derrick respectively, improving the stability of the equipment.

[0027] A roller 10 is rotatably installed on the top of the supporting bracket 1, and the roller 10 is horizontally arranged. The roller 10 can rotate freely. During the process of jacking up the derrick, relative movement will inevitably occur between the derrick and the supporting bracket 1. By setting the roller 10, damage to the derrick or the supporting bracket 1 caused by their relative movement can be avoided.

[0028] When lifting the derrick, refer to the appendix Figures 4 - 6 , before lifting, the derrick is supported on the roller 10. At this time, the contact point between the derrick and the roller 10 is the support point a. During the lifting process, since the equipment is fixed during the lifting process, and the derrick will slowly rise with the end fulcrum as the axis. After being lifted to the specified position, the contact point between the roller 10 and the derrick is the support point b. The support point a is located on the side of the support point b close to the derrick fulcrum, and there is an interval between the support point a and the support point b. That is, during the lifting process, relative movement will inevitably occur between the derrick and the lifting device.

[0029] Taking the example of lifting the derrick from a height of 3000mm to 6800mm, the distance between the support points a and b before and after lifting is about 400mm, that is, the relative displacement between the lifting device and the derrick is about 400mm.

[0030] The two traveling devices 8 on both sides are fixedly connected by a connecting beam 14. There are two connecting beams 14 arranged side by side and at intervals. Each second base 13 and the first base 12 are arranged at intervals, and a gap for the corresponding connecting beam 14 to pass through is formed between each second base 13 and the first base 12. Both ends of each connecting beam 14 are connected with a lifting device 5, and the lifting device 5 is arranged opposite to the gap. When the lifting device 5 works, the lifting device 5 extends to drive the traveling device 8 to contact the ground downward, and the base is away from the ground. At this time, the whole equipment is supported on the ground by the traveling device 8. The traveling device 8 moves in the specified direction. After moving to the specified position, the lifting device 5 contracts, driving the traveling device 8 to move upward away from the ground. At this time, the whole equipment is supported on the ground by the first base 12 and the second base 13, and then the main lifting device works.

[0031] The traveling device 8 is a crawler-type traveling device, which can directly adopt the traveling device in the utility model patent CN220317276 U, a self-propelled oil drilling derrick lifting device and its control system. The specific structure thereof will not be elaborated herein.

[0032] The main body of the lifting device includes hydraulic cylinders 9. The hydraulic cylinders 9 are multi-stage hydraulic cylinders. There are two hydraulic cylinders 9 arranged side by side perpendicular to the traveling direction. The bottom of each hydraulic cylinder 9 is fixed to the first base 12, and the movable end of each hydraulic cylinder 9 is fixedly connected to the support bracket 1. The multi-stage compression cylinder is a prior art, and its structure and working principle will not be elaborated herein.

[0033] The main body of the lifting device further includes connecting plates 2. There are 4 connecting plates 2. One end of the connecting plate 2 is fixedly connected to the multi-stage support column 3, and the other end is fixedly connected to the hydraulic cylinder 9, increasing the stability of the lifting device.

[0034] The main body of the lifting device further includes a cross beam 7 and connecting rods 4. The cross beam 7 is fixedly arranged in the middle of the guiding device. The cross beam 7 is symmetrically arranged on both sides of the guiding device. The two cross beams 7 reinforce the guiding device; the two cross beams 7 are fixed to the guiding device through fixing blocks, so that there is a spaced arrangement between the lifting device 5 and the base, facilitating the up and down movement of the traveling device 8 and the lifting device 5 on both sides of the base; there are two connecting rods 4, and the connecting rods 4 are arranged at intervals in the space formed by the guiding device. The two ends of the connecting rods 4 are fixedly installed on the cross beam 7.

[0035] Two guiding devices are arranged side by side on each first base 12. The guiding device includes multi-stage support columns 3. There are two multi-stage support columns 3 symmetrically arranged on both sides of each second base 13. Each multi-stage support column 3 includes two arranged side by side along the traveling direction. The guiding device, the cross beam 7 and the connecting plate 2 form a stable support space with the base.

[0036] Refer to the attached Figures 1 - 2 , in this embodiment, the upper part of the second base 13 bulges in the middle and the lower part extends outward on both sides. The upper part of each second base 13 faces the first base 12. Support frames are arranged on the lower part of each second base 13, and the support frames make the equipment stably supported.

[0037] When this remote control self-propelled crawler roller type oil drilling derrick disassembly and assembly lifting device is working, usually four devices work simultaneously. Two of them are in a group. The two devices in the same group lift the derrick. After the lifting reaches the upper dead center of the stroke of this group of devices, the other two devices in the group travel to the bottom of the derrick and are located in front of the traveling direction of the first group of devices, and then lift the derrick again. After both devices in this group are lifted to the upper dead center of the stroke, at this time, the two devices in the first group move to the front of the two devices in this group again and lift the derrick. Work in this way repeatedly until the derrick is erected.

[0038] This device can not only be used for the lifting of the derrick, but also for the lowering of the derrick. Its working process is opposite to that of the derrick lifting process, that is, this device is preferably located at the upper dead center of the stroke and supports the derrick column. After the derrick is completely lifted by this device, this device can drive the derrick to lower. At least two groups of devices work alternately to ensure the smooth lowering of the derrick.

[0039] A 4G module or a 5G module is installed on the remote control self-propelled crawler roller type oil drilling derrick disassembly, installation and lifting device. Preferably, a 5G module is installed, so that remote control can be realized, and its work can be controlled through a remote control terminal, which is convenient to use.

[0040] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still fall within the protection scope of the technical solution of the present invention.
