Description

Technical Field

[0001] The utility model relates to the technical field of derrick transportation, and more specifically, to a derrick transportation device. Background Art

[0002] Competition in the domestic and international drilling engineering service markets is fierce. Drilling contractors not only require technologically advanced and reliable drilling rigs, but also have increasingly stringent cost control requirements. Among them, relocation costs and time control are issues of particular concern to engineering service providers. Improving the mobility of drilling rigs, reducing the workload of drilling rig disassembly and installation, and shortening the time it takes to relocate drilling rigs have become common goals pursued by oil companies and drilling contractors. The rapid mobility of drilling rigs has also become a core competitive technology for drilling equipment manufacturers. With the development of oil rig relocation technology, the overall horizontal movement of derricks has been widely used in oil fields. Overall derrick relocation refers to the use of derrick transport equipment to transport the derrick to a designated location while the derrick is in a lying position without disassembling the main structure.

[0003] The derrick transport device used in the prior art is generally composed of a derrick transport vehicle, a bracket, a tractor, etc. The connection method between the derrick transport vehicle and the derrick is U-bolt connection, and there is a risk of the U-bolt being sheared during transportation; for special drilling rig structures, due to the structural limitations of the drilling rig and the base, the installation and alignment of the derrick and the base is relatively difficult. The existing derrick transport vehicle has a wide wheel base, and the transport vehicle can only transport the derrick to the front of the base and rely on a crane to complete the docking of the derrick and the base, or there is no horizontal adjustment device, which cannot meet the horizontal adjustment of the derrick, and the installation of the derrick docking base is also difficult.

They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0025] like Figure 1-5As shown, the derrick transport device of the present invention includes a derrick transport vehicle 1 and a tractor 2. The derrick transport vehicle 1 includes a frame 3. The bottom of the frame 3 is provided with wheels 4 in pairs along the longitudinal transport direction of the derrick 20. A vertically retractable jacking bracket 5 is installed on the frame 3. A cross frame 6 is provided on the top of the jacking bracket 5 for horizontal sliding along the derrick 20. A horizontal cylinder 7 is connected between the jacking bracket 5 and the bottom of the cross frame 6. The cross frame 6 is driven to move laterally by the horizontal cylinder 7. Positioning pins 8 and connecting rod ear plates 9 are provided at the top corners of the cross frame 6 corresponding to the bottom of the derrick 20. The connecting rod ear plates 9 are connected to the corresponding bottom positions of the derrick 20 through pin shafts. Telescopic support legs 10 are provided downwardly at the top corners of the frame 3 on the horizontal plane. The telescopic support legs 10 are used to support the derrick transport vehicle 1. A towing saddle 11 is provided on the tractor 2 for connecting to the front end bottom of the derrick 20 when it is in a lying state.

[0026] The derrick transport vehicle 1 is used to support the rear part of the derrick 20 when the derrick 20 is transported in an overall horizontal position without being disassembled. The derrick transport vehicle 1 has an up and down adjustment function by setting a lifting bracket 5, and has a left and right adjustment function by sliding a cross frame 6 and a horizontal cylinder 7. The derrick transport vehicle 1 is used to achieve alignment with the derrick 20 and the drilling rig base 22. During transportation, the wire rope rewinder is placed on the derrick transport vehicle 1 and fixed with a pin shaft. The derrick transport vehicle 1 and the derrick 20 are connected by a connecting rod ear plate 9 through a common pin shaft.

[0027] The specific working process is as follows, including the derrick 20 from the well site working state to the transportation state:

[0028] (1) Place the derrick 20 transport device in front of the drilling rig base 22 (on the ramp side), and accurately support it at the corresponding position inside the drilling rig base 22 through the telescopic support legs 10 on the outside of the frame 3.

[0029] (2) The derrick 20 is lowered, and the front end of the derrick 20 is supported on the high support 23 of the derrick 20.

[0030] (3) Use a hydraulic station to provide power, place it on the base of the drilling rig, start the jacking bracket 5 and the horizontal cylinder 7, extend the jacking bracket 5 to a certain height and fix the height position, adjust the horizontal frame 6 to the appropriate position, and when everything is ready, lower the derrick 20.

[0031] (4) A traction device 24 for connecting to the towing saddle 11 is installed at the front of the derrick 20, and the towing saddle 11 is installed on the tractor 2.

[0032] (5) Use a crane to lift the front end of the derrick 20 and remove the high support 23.

[0033] (6) Use a crane to lift the upper end of the derrick 20 and slowly lower it so that the holes of the mounting base of the derrick 20 fall exactly on the positioning pins 8 of the derrick transport vehicle 1, and the bottom surface of the derrick 20 is in full contact with the cross frame 6.

[0034] (7) Release the height fixed state of the jacking support 5, continue to slowly lower the front part of the derrick 20, and the jacking support 5 slowly descends and retracts.

[0035] (8) When the traction device 24 at the front of the derrick 20 lowered by the crane is at the same height as the tractor 2, the tractor 2 reverses, the traction device is connected to the towing saddle 11, and the tractor 2 is locked.

[0036] (9) Remove the connecting pins between the derrick 20 and the drilling rig base 22.

[0037] (10) The rope reversing machine is hoisted onto the derrick 20 carrying trailer and connected and fastened.

[0038] (11) Tractor 2 pulls forward a certain distance and stops.

[0039] (12) Operate and control the jacking bracket 5. When the derrick 20 descends to the lowest position, lock the height position of the jacking bracket 5; and connect the derrick 20 and the connecting rod ear plate 9 with a pin shaft.

[0040] (13) Remove the hydraulic pipeline connected to the hydraulic power drive mechanism and wrap the oil inlet and return joints of the cylinder with clean joint caps or plastic cloth to prevent dirt from entering the hydraulic oil.

[0041] (14) The derrick 20 reaches the moving state, with the tractor 2 taking the initiative and the derrick transport vehicle 1 following.

[0042] The derrick 20 transportation device of the present invention includes a derrick moving vehicle 1 and a tractor 2. The derrick moving vehicle 1 is provided with a jacking bracket 5 and a cross frame 6 in sequence. The jacking bracket 5 has a vertical telescopic function and a horizontal oil cylinder 7 is provided between the cross frame 6. The positioning pins 8 and the connecting rod ear plates 9 on the top of the cross frame 6 are arranged in accordance with the structural shape of the derrick 20. Compared with the conventional derrick 20 moving trailer, the derrick moving vehicle 1 has an adjustable top surface of the cross frame 6 in the up and down and left and right directions, and the derrick moving vehicle 1 is reliably connected to the derrick 20 positioning pins 8, which not only improves work efficiency and reduces work intensity, but also reduces the risk during the installation process. It is suitable for the docking installation of derricks 20 with different structural forms, and the overall level is not disassembled for transportation, and the derrick 20 can be moved and transported conveniently and quickly.

[0043] In another technical solution, Figure 4-5 As shown, the lifting support 5 includes:

[0044] A vertical limiting sleeve 12 is symmetrically fixed to the frame 3 and disposed near both sides thereof. A pair of external pin holes 13 are formed in the middle of the upper end of the vertical limiting sleeve 12 along the horizontal direction.

[0045] A vertical lifting cylinder 14 is symmetrically arranged between a pair of vertical limiting sleeves 12, with the telescopic end of the vertical lifting cylinder 14 connected to a corresponding position of the bottom of the cross frame 6, and the bottom of the vertical lifting cylinder 14 connected to a corresponding position of the top surface of the frame 3;

[0046] A sliding column 15 is slidably arranged in each vertical limit sleeve 12. The length of the sliding column 15 is greater than the height of the vertical limit sleeve 12. A top frame is connected to the top of the sliding column 15, and the top frame is slidably connected to the cross frame 6. An inner pin hole is opened in the middle of the sliding column 15 along the horizontal direction. Several inner pin holes are arranged at vertical intervals and are located in the same vertical plane as the outer pin hole 13. A limit pin shaft is inserted into a pair of outer pin holes 13 and an inner pin hole at the same height to protect the vertical lifting cylinder 14.

[0047] The vertical limit sleeve 12 serves as the main limit structure, and the sliding column 15 is fixedly connected to the cross frame 6 as a whole. The sliding column 15 is inserted downward into the vertical limit sleeve 12. By arranging multiple inner pin holes vertically on the sliding column 15, the cross frame 6 can be located at different required heights. The limit pin shaft is inserted into the outer pin hole 13 and the inner pin hole to protect and support the vertical lifting cylinder 14. Generally, four vertical lifting cylinders 14 are arranged symmetrically.

[0048] In another technical solution, Figure 4-5 As shown, diagonal braces 16 are connected between the longitudinal front and rear sides of the vertical limiting sleeve 12 and the top surface of the vehicle frame 3 to reinforce the structure of the vertical limiting sleeve 12.

[0049] In another technical solution, Figure 1 As shown, the derrick transport vehicle 1 is provided with a pair of wheels 4, and the frame 3 is provided with a towing eye on the front side in the longitudinal transport direction. The connection structure of the frame 3, the jacking bracket 5, and the cross frame 6 can significantly shorten the wheelbase of the pair of wheels 4, allowing entry into the base of the substructure and a single reverse vehicle into position. This adapts to the rearward lying of the drilling rig substructure 22 in a low position and the docking and transportation of the derrick 20 on the drilling floor. The derrick transport vehicle 1 itself can be connected to a towing device for movement via the towing eye.

[0050] In another technical solution, Figure 4-5 As shown, end frames 17 are provided at both ends of the cross frame 6 along the longitudinal extension to form an I-shaped structure in the horizontal plane. The longitudinal front and rear ends of the end frame 17 are respectively provided with the positioning pin 8 and the connecting rod ear plate 9, which are jointly connected to the derrick 20 to increase the support and connection range with the derrick 20.

[0051] In another technical solution, Figure 4-5As shown, a limiting inclined block 18 is provided upwardly on the inner side of the lateral end of the derrick 20 corresponding to the top of the end frame 17, which can serve as a guiding structure and a limiting structure when the derrick 20 slowly moves downward, so as to facilitate the connection between the derrick 20 and the connecting rod ear plate 9 at the bottom of the cross frame 6.

[0052] In another technical solution, Figure 1-5 As shown, the frame 3 is detachably connected to a placement platform 19 at the rear side in the longitudinal transport direction for placing a hydraulic rope rewinder 21 , thereby improving the usability of the derrick transport vehicle 1 and flexibly adapting to space requirements.

[0053] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and drawings shown and described herein.
