Description

Technical Field

[0001] This utility model relates to the field of petroleum equipment technology, and in particular to a U-shaped drilling rig base trailer. Background Technology

[0002] Trailers are widely used in the transportation and relocation of oil drilling equipment. Conventional technologies employ various methods for transporting drilling rigs and their bases. The most common methods include modular drilling rigs (which can be disassembled into smaller units), rigs with self-propelled mechanisms (such as tracked or walking mechanisms), and truck-mounted rigs. Modular drilling rigs are not very flexible, requiring significant manpower and time for disassembly and assembly. Mobile drilling rigs are relatively expensive, have short travel distances and slow speeds, and are only suitable for short-distance relocations. Truck-mounted drilling rigs, on the other hand, offer faster movement, lower costs, and are not limited by distance, making them widely popular.

[0003] In the existing technology, the vehicle-mounted transportation of drilling rig bases usually involves adding two sets of wheels to both sides of the base trailer or making additional walking units. These two solutions either increase the overall width of the vehicle, turning it into an extra-wide vehicle, or increase the height of the base trailer, making the base trailer structure less compact, bulky, and less flexible, which is not conducive to transportation.

[0004] Therefore, it is necessary to propose a U-shaped drilling rig base trailer to reduce the size of the base trailer and improve its transportation flexibility. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of large size and poor flexibility of existing vehicle-mounted base trailers, and now a zigzag-shaped drilling rig base trailer is provided.

[0006] The technical solution of this utility model is:

[0007] A U-shaped drilling rig base trailer includes a trailer frame with a gooseneck beam rotatably connected to the trailer frame. The trailer frame includes a front section, a rear section, and a frame ridge located between the two. The frame ridge protrudes upward to form a cavity between the front and rear sections of the frame. A liftable wheel system is provided in the cavity. A front hydraulic cylinder for supporting the lifting and lowering of the trailer frame is installed at one end of the gooseneck beam on the trailer frame. A tilting hydraulic cylinder for driving the rotation of the gooseneck beam is installed on the trailer frame.

[0008] Furthermore, the traveling wheel system includes a rear hydraulic cylinder, an upper guide sleeve, and a lower guide sleeve. The lower guide sleeve and the upper guide sleeve are nested together. The rear hydraulic cylinder drives the lower guide sleeve to slide relative to the upper guide sleeve. A bridge wheel is installed at the bottom of the lower guide sleeve. The nesting of the upper and lower guide sleeves enables the height adjustment of the traveling wheel system. In the transportation state, the bridge wheel contacts the ground and provides support. In the operation state, the bridge wheel is retracted.

[0009] Furthermore, connecting beams are fixedly connected to both sides of the upper guide sleeve, and the connecting beams are fixedly connected to the back of the vehicle frame, thereby fixing the upper guide sleeve to the trailer frame.

[0010] Furthermore, both the upper and lower guide sleeves are provided with pin holes, and positioning pins are installed in the pin holes. The positioning pins lock and fix the upper and lower guide sleeves. After the height of the upper and lower guide sleeves is adjusted, the positioning pins are inserted into the pin holes to lock and fix the upper and lower guide sleeves.

[0011] Furthermore, the bridge wheel and the lower guide sleeve are rotatably connected via an axle, and the rotation of the bridge wheel enables the entire trailer frame to move.

[0012] Furthermore, the rear hydraulic cylinder is fixedly installed inside the upper guide sleeve, which helps protect the rear hydraulic cylinder while saving overall volume.

[0013] Furthermore, a front hydraulic cylinder mounting seat is fixedly connected to the end of the front section of the frame. The front hydraulic cylinder mounting seat is located on both sides of the front section of the frame, and the front hydraulic cylinder is fixedly connected to the front hydraulic cylinder mounting seat.

[0014] Furthermore, a tilting cylinder connecting seat is fixedly connected to the front end of the frame, and the tilting cylinder is rotatably connected to the tilting cylinder connecting seat.

[0015] Furthermore, a connecting seat is fixedly connected to the front end of the frame, and the connecting seat is rotatably connected to the gooseneck beam.

[0016] Furthermore, the rear section of the frame has two parallel sections, with a tie beam between them, and both ends of the tie beam are fixedly connected to the two rear sections of the frame respectively.

[0017] This utility model discloses a U-shaped drilling rig base trailer, which designs the trailer frame into three parts: the front section of the frame, the rear section of the frame, and the frame spine. The upward protrusion of the frame spine forms a cavity that can better accommodate the wheel system, so that the wheel set in the wheel system does not increase the width of the vehicle or the height of the base trailer. Compared with traditional technology, this technical solution ensures that the base trailer has a compact structure, avoids the bulky and redundant size of the base trailer, improves the flexibility of the base trailer, and facilitates transportation.

[0027] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0028] Example 1:

[0029] like Figure 1 and Figure 2 As shown, this embodiment provides a U-shaped drilling rig base trailer, including a trailer frame 4. The trailer frame 4 is provided with a gooseneck beam 1 rotatably connected to the trailer frame 4. The trailer frame 4 is generally U-shaped and consists of three sections: a front section 17, a rear section 15, and a frame spine 16 located between the two. The three sections are not limited to H-beams or channel steel and form a three-longitudinal beam structure. The front section 17, the rear section 15, and the frame spine 16 located between the two are fixed by screws or welding. The frame spine 16 protrudes upward to form a cavity between the front section 17 and the rear section 15. The cavity is provided with a liftable wheel system 5. A front hydraulic cylinder 3 for supporting the lifting and lowering of the trailer frame 4 is installed at one end of the gooseneck beam 1 on the trailer frame 4. A tilting hydraulic cylinder 2 for driving the rotation of the gooseneck beam 1 is installed on the trailer frame 4.

[0030] Preferred, such as Figure 4The walking wheel system 5 includes a rear hydraulic cylinder 12, an upper guide sleeve 10, and a lower guide sleeve 9. The lower guide sleeve 9 and the upper guide sleeve 10 are nested together in a "U" shape. The rear hydraulic cylinder 12 is located within the "U" shaped cavity. The rear hydraulic cylinder 12 drives the lower guide sleeve 9 to slide relative to the upper guide sleeve 10. A bridge wheel 8 is installed at the bottom end of the lower guide sleeve 9. Figure 5 and Figure 6 The upper guide sleeve 10 and the lower guide sleeve 9 are nested together to achieve height adjustment of the walking wheel system 5. In the transportation state, the bridge wheel 8 contacts the ground and provides support. In the operation state, the bridge wheel 8 is retracted upward. Preferably, the upper guide sleeve 10 is welded with connecting beams 11 on both sides. The connecting beams 11 are welded to the frame spine 16. The upper guide sleeve 10 is fixed to the trailer frame 4 through the connecting beams.

[0031] Preferred, such as Figure 5 and Figure 6 Both the upper guide sleeve 10 and the lower guide sleeve 9 are provided with pin holes, and positioning pins 13 are installed in the pin holes. The positioning pins 13 lock and fix the upper guide sleeve 10 and the lower guide sleeve 9. After the height of the upper guide sleeve 10 and the lower guide sleeve 9 is adjusted, the positioning pins 13 are inserted into the pin holes to lock and fix the upper guide sleeve 10 and the lower guide sleeve 9. Preferably, the bridge wheel 8 and the lower guide sleeve 9 are rotatably connected by the axle 7. The axle 7 is equipped with a bearing. The rotation of the bridge wheel 8 can realize the overall movement of the trailer frame 4. Preferably, the rear hydraulic cylinder 12 is screwed in the upper guide sleeve 10, which is beneficial to protect the rear hydraulic cylinder 12 and saves the overall volume. Preferably, the front hydraulic cylinder mounting seat 18 is welded to the end of the front section 17 of the frame. The front hydraulic cylinder mounting seat 18 is located on both sides of the front section 17 of the frame. The front hydraulic cylinder 3 is screwed to the front hydraulic cylinder mounting seat 18.

[0032] Preferred, such as Figure 3 As shown, a tilting hydraulic cylinder connecting seat 20 is welded to the end of the front section 17 of the frame. The tilting hydraulic cylinder 2 and the tilting hydraulic cylinder connecting seat 20 are rotatably connected by a pin. Preferably, a connecting seat 19 is screwed to the end of the front section 17 of the frame. The connecting seat 19 and the gooseneck beam 1 are rotatably connected by a pin. The end of the gooseneck beam 1 is connected to the connecting seat 19. The connecting seat 19 is divided into two parts, left and right. Each part has two sets of pin holes, front and rear. The rear pin hole is the rotating pin hole of the gooseneck beam 1, and the front pin hole is the positioning pin hole 13. Preferably, there are two rear sections 15 of the frame, which are arranged in parallel. A tie beam 14 is provided between the two rear sections 15 of the frame. The two ends of the tie beam 14 are respectively fixedly connected to the two rear sections 15 of the frame with screws. The tie beam 14 plays the role of stabilizing the main structure.

[0033] like Figure 7 and Figure 8 The process of trailer 4 transitioning from the drilling state to the next drilling state is as follows:

[0034] 1. Lay the base down and place it on the trailer frame 4, connecting the support rod 6.

[0035] 2. The rear hydraulic cylinder 12 is pressurized and retracted by an appropriate distance to replace the positioning pin 13 in bearing the weight of the bridge wheel 8. The positioning pin 13 is then pulled out.

[0036] 3. Remove the auxiliary drilling equipment in front of the trailer, tilt the hydraulic cylinder 2 to pressurize and retract, drive the gooseneck beam 1 to rotate around the rear pin hole of the connecting seat 19, after the gooseneck beam 1 is horizontal, pass through the front pin hole of the connecting seat 19, tilt the hydraulic cylinder 2 to release pressure, and the gooseneck beam 1 is in place.

[0037] 4. The rear hydraulic cylinder 12 is pressurized and extended, driving the tire to contact the ground. At the same time, the front hydraulic cylinder 3 is pressurized and extended. The front and rear hydraulic cylinders 12 are synchronized until the lower pin hole of the lower guide rail is coaxial with the outer pin hole of the upper guide rail, and the positioning pin 13 is inserted.

[0038] 5. The rear hydraulic cylinder 12 is pressurized and retracted. At the same time, the front hydraulic cylinder 3 is pressurized and retracted until the weight borne by the rear hydraulic cylinder 12 is completely borne by the positioning pin 13. The front hydraulic cylinder 3 is locked to maintain a constant height, and the rear hydraulic cylinder 12 is depressurized.

[0039] 6. Connect the traction pin from the cab to the gooseneck beam 1. The front hydraulic cylinder 3 is pressurized, retracted, and lifted off the ground. The load is fully borne by the cab, and the cab is now in transport mode. The cab can then tow the trailer frame 4.

[0040] 7. Upon reaching the next drilling location, the front hydraulic cylinder 3 is pressurized, extends, touches the ground, and takes over the load from the cab. The cab disengages from the gooseneck beam 1 traction pin and drives away.

[0041] 8. Pressurize the hydraulic cylinder 2 by flipping it over, pull out the front pin of the connecting seat 19, drive the gooseneck beam 1 to rotate around the rear pin of the connecting seat 19 until it reaches 90°, the gooseneck beam 1 contacts the support seat of the trailer seat, depressurize the hydraulic cylinder 2 by flipping it over, and connect the drilling rig auxiliary equipment.

[0042] 9. The rear hydraulic cylinder 12 is pressurized and extended until it completely replaces the locating pin 13 to bear the weight. At this point, the rear hydraulic cylinder 12 and the front hydraulic cylinder 3 extend together a suitable distance, and the locating pin 13 is pulled out. Then, the rear hydraulic cylinder 12 and the front hydraulic cylinder 3 retract simultaneously until the bottom surface of the trailer frame 4 contacts the ground. At this point, the weight of the drilling rig base is borne by the trailer frame 4, and the front hydraulic cylinder 3 is depressurized. The rear hydraulic cylinder 12 continues to retract until the pin hole on the lower guide sleeve 9 is coaxial with the pin hole on the upper guide sleeve 10, thus passing through the locating pin 13. The rear hydraulic cylinder 12 is depressurized. At this point, the tires are off the ground, and the weight is borne by the locating pin 13.

[0043] 10. Remove support rod 6, lift the base, and enter drilling mode.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made in accordance with the scope of the claims of this utility model should fall within the technical scope of this utility model.
