[0001] The present invention relates to the technical field of oil extraction, and particularly to a fracturing manifold truck and an application method thereof. Background Art

[0002] During the process of oil extraction operations, hydraulic fracturing is usually adopted to break the formation structure, thereby improving the underground flow environment of oil and increasing the production of oil wells. When conducting fracturing operations, several fracturing trucks are usually required to operate simultaneously. At this time, a fracturing manifold system is used to collect the liquid output of the fracturing trucks to increase the flow rate and pressure of the fracturing medium.

[0003] The existing invention patent application with the publication number CN118933696A provides a vehicle-mounted high-pressure fracturing manifold, belonging to the technical field of vehicle-mounted high-pressure fracturing manifolds. The vehicle-mounted high-pressure fracturing manifold includes a support base, vehicle-mounted fixing parts, an installation component, a manifold component, a docking component, and a valve component. Vehicle-mounted fixing parts are provided at positions corresponding to the support base on the vehicle body. The vehicle-mounted fixing parts are used to fix the support base on the vehicle body and reduce the influence of vehicle body shaking on the manifold component; the manifold component is fixed on the top of the vehicle-mounted fixing parts through the installation component, and the installation component is used to ensure the stability of the manifold component fixed on the top of the vehicle-mounted fixing parts; the manifold component includes a high-pressure main pipe, a shunt pipe, and a discharge pipeline, and the high-pressure main pipe is a cylindrical pipe structure.

[0004] In the above technical solution, the vehicle-mounted high-pressure fracturing manifold mentioned therein fixes the manifold component on the vehicle body through the support base, which is a common structure of existing vehicle-mounted fracturing manifolds; currently, most vehicle-mounted fracturing manifolds are carried by trailers. During application, the manifold component needs to be lifted by a lifting device and placed on the ground, and then the liquid output pipeline of the fracturing truck is connected. This assembly process is time-consuming and cannot be horizontally adjusted according to the ground; especially for some pipelines in the manifold component, they are driven by hydraulic cylinders to automatically dock with the fracturing truck. If the attitude of the manifold component is unstable, it will lead to inconvenient connection, and even the manifold component cannot be connected to the fracturing truck. After flushing the manifold component later, it is also not convenient to drain. Summary of the Invention

[0050] S3. Disconnect the tractor head from the first carrier, position the first carrier, and unload the engineering equipment on the first carrier;

[0054] S7. Re-carry the engineering equipment onto the first carrier and tow the first carrier and the second carrier through the tractor head.

[0055] The fracturing manifold truck and its application method of the present invention have the following beneficial effects compared with the prior art:

[0056] (1) By setting the first carrier and the second carrier and arranging a power component on the second carrier, it can drive the first carrier to swing up and down with the front wheel set as the axis. After the manifold assembly is carried on the first carrier, the attitude of the manifold assembly can be adjusted, which facilitates the connection between the manifold assembly and the fracturing truck and also facilitates emptying; the manifold assembly is hoisted at the bottom of the first carrier, which makes the overall height of the manifold assembly lower and convenient for manual assembly work;

[0057] (2) The rear wheel set connected to the second carrier is set as a self-driven wheel set or is provided with a traveling drive mechanism. When adjusting the attitude of the first carrier, the second carrier can move synchronously towards the first carrier, so as to ensure that the position of the front wheel set of the first carrier remains unchanged, thereby improving the stability of the adjustment;

[0058] (3) One end of the rear frame of the second carrier is open, and a first U-shaped frame is provided for structural reinforcement. At the same time, a carrier frame is provided for installing the power component. Since both the first U-shaped frame and the carrier frame extend downward, after installing the power component, the space of the second carrier can be fully utilized, and it is also convenient for the connection between the power component and the first carrier. At the same time, other engineering equipment can be carried on the upper parts of the first carrier and the second carrier, which expands the carrying space of the carrier and improves the transportation capacity.

[0059] (4) When the power component is working, the motor drives the speed reducer, and then relies on the speed reducer to drive the worm and the worm wheel to rotate. Then, the swing arm can be driven to swing through the rotating shaft. Since the swing arm is hinged to the first carrier, the first carrier can realize the pitching swing adjustment up and down, so as to ensure the correct attitude. At the same time, the second carrier moves synchronously towards the first carrier, thereby reducing the load of the power component.

[0060] (5) For the opposite sides of the rear frame in the second carrier and the front frame in the first carrier, both are set as open structures. The rear frame is connected with a first U-shaped frame, while the front frame installs a second U-shaped frame through two L-shaped frames. In this way, when the first carrier swings, the second U-shaped frame will move to the inside of the first U-shaped frame, thus avoiding interference problems. This structure improves the structural compactness of the first carrier and the second carrier.

[0061] (6) A pipe rack assembly is provided on the first carrier. During operation, it can slide and clean the pipeline so that the spray pipe is docked with the functional pipeline carried by the first carrier. In this way, by supplying water into the shaft pipe, the flushing work of the pipeline can be realized, which can not only clean the pipeline but also play a role in pipeline detection. At the same time, in cooperation with the push rod, one end of the functional pipeline can be lifted upward with the shaft pipe as the axis, so as to disengage from the U-shaped notch of the pipe rack, facilitating subsequent hoisting.

[0074] Next, in combination with the implementation manners of the present invention, the technical solutions in the implementation manners of the present invention will be clearly and completely described. Obviously, the described implementation manners are only a part of the implementation manners of the present invention, rather than all of the implementation manners. Based on the implementation manners in the present invention, all other implementation manners obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0075] As Figures 1 to 10 shown, the fracturing manifold vehicle of the present invention includes a first carrier 1, a second carrier 2, a front wheel set 3, a rear wheel set 4, a manifold assembly 5, a power component 6, a hydraulic cylinder 7, a connecting piece 8, a pipe rack assembly 9 and a lifting equipment 10

[0076] As Figure 1 ,Figure 5 and Figure 6 As shown in Figure 6 , the first carrier 1 and the second carrier 2 are arranged in parallel; the front wheel set 3 is rotatably arranged on the first carrier 1; the rear wheel set 4 is rotatably arranged on the second carrier 2, and there are two rear wheel sets 4 arranged in parallel, and the rear wheel set 4 is a self-driven wheel set; the pipe string assembly 5 is hoisted at the bottom of the first carrier 1; the power component 6 is arranged on the second carrier 2, and the power component 6 is used to drive the first carrier 1 to swing up and down with the front wheel set 3 as the axis.

[0077] In the above structure, the first carrier 1 and the second carrier 2 are of a split structure and are connected by the power component 6; the pipe string assembly 5 is carried on the first carrier 1. In this way, during application, the power component 6 can drive the first carrier 1 and the pipe string assembly 5 to swing up and down with the front wheel set 3 as the axis, so as to adjust the attitude of the pipe string assembly 5, which facilitates the connection between the pipe string assembly 5 and the fracturing truck, and at the same time facilitates the evacuation of the pipe string assembly 5.

[0078] Specifically, the front wheel set 3 and the rear wheel set 4 are connected to the first carrier 1 and the second carrier 2 through a suspension assembly composed of components such as leaf springs to form a basic frame structure.

[0079] The pipe string assembly 5 is hoisted at the bottom of the first carrier 1, which makes the overall height of the pipe string assembly 5 relatively low and facilitates manual assembly work. That is, after the fracturing pipe truck arrives at the site and the tractor head detaches, after adjusting the horizontal attitude of the first carrier 1 and the pipe string assembly 5 through the power component 6, the pipe string assembly 5 can be connected to the liquid outlet pipeline of the fracturing truck without moving the pipe string assembly 5 to the ground surface, which improves the convenience of assembly.

[0080] Specifically, the rear wheel set 4 connected to the second carrier 2 is set as a self-driven wheel set or is provided with a traveling drive mechanism. In this way, when adjusting the attitude of the first carrier 1, the second carrier 2 can move synchronously towards the first carrier 1, so as to ensure that the position of the front wheel set 3 of the first carrier 1 remains unchanged, thereby improving the stability of the adjustment; the rear wheel set 4 has an independent power source, for example, a motor is arranged on the second carrier 2, and then the rear wheel set 4 is driven to rotate through transmission components such as a transmission shaft.

[0081] During specific application, the first carrier 1 is towed by a tractor head, and an independent brake component or a limiting component is arranged in the front wheel set 3 at the bottom of the first carrier 1, so that after the tractor head detaches from the first carrier 1, when the power component 6 adjusts the first carrier 1, the front wheel set 3 does not move, thereby ensuring the stability of the position.

[0082] Among them, the brake component can adopt an existing mechanical handbrake, that is, a parking mechanism composed of components such as a pull rod, a ratchet, a steel cable and a brake shoe is used to lock the front wheel set 3, so as to realize the limitation of the first carrier 1, so that when the first carrier 1 is adjusted in pitch, the position can be ensured not to change.

[0083] As Figure 9 and Figure 10 shown, the second carrier 2 includes a rear frame body 21, a first U-shaped frame 22 and a carrier frame 23. Among them, the rear frame body 21 is rotatably connected to the rear wheel set 4, and one end of the rear frame body 21 facing the first carrier 1 is open; the open end of the first U-shaped frame 22 is connected to the open end of the rear frame body 21; the carrier frame 23 is connected to the rear frame body 21, and both the first U-shaped frame 22 and the carrier frame 23 extend downward; the power component 6 is arranged on the carrier frame 23;

[0084] In the above structure, one end of the rear frame body 21 of the second carrier 2 is open, and a first U-shaped frame 22 is provided for structural strengthening, and at the same time a carrier frame 23 is provided for installing the power component;

[0085] Among them, since both the first U-shaped frame 22 and the carrier frame 23 extend downward, that is, extend toward the ground, this makes the carrier frame 23 located inside the second carrier 2 as a whole and arranged downward. Therefore, after the power component 6 is carried, the space of the second carrier 2 is fully utilized;

[0086] Among them, the first U-shaped frame 22 is provided, which connects the opening of the rear frame body 21, which improves the overall structural strength of the second carrier 2. At the same time, the structure of the first U-shaped frame 22 extending downward also facilitates the connection between the power component 6 and the first carrier 1;

[0087] Furthermore, other engineering equipment can be carried on the upper parts of the first carrier 1 and the second carrier 2, which expands the carrying space of the carrier and improves the transport capacity.

[0088] As Figure 2 and Figure 10 shown, the power component 6 includes a speed reducer 61, a motor 62, a worm 63, a worm gear 64, a rotating shaft 65 and a swing arm 66. Among them, the speed reducer 61 is arranged on the carrier frame 23; the motor 62 is arranged on the carrier frame 23, and the main shaft of the motor 62 is connected to the input shaft of the speed reducer 61; the worm 63 is connected to the output shaft of the speed reducer 61; the worm gear 64 is arranged on the rotating shaft 65, the rotating shaft 65 is connected to the carrier frame 23 through a bearing seat, and the worm gear 64 meshes with the worm 63; one end of the swing arm 66 is connected to the rotating shaft 65, and the other end is hinged to the first carrier 1;

[0089] In the above structure, when adjusting the attitude of the first carrier 1, the power component 6 drives the speed reducer 61 to work with the motor 62, and then relies on the speed reducer 61 to drive the worm 63 and the worm gear 64 to rotate, and then the swing arm 66 can be driven to swing through the rotating shaft 65. Since the swing arm 66 is hinged to the first carrier 1, the first carrier 1 can realize the pitching swing adjustment up and down, so as to ensure the correct attitude of the pipe assembly 5;

[0090] In this adjustment, the front wheel set 3 under the first carrier 1 remains stationary relative to the ground. At this time, the rear wheel set 4 of the second carrier 2 moves synchronously towards or away from the first carrier 1 through its drive structure during adjustment, so as to adapt to the distance change generated between the first carrier 1 and the second carrier 2 during adjustment, which is beneficial to reducing the load of the power component 6.

[0091] The above power component 6 can also be replaced by various driving components such as telescopic cylinders and connecting rods.

[0092] Such as Figure 4 、 Figure 7 and Figure 8 As shown, the first carrier 1 includes a front frame body 11, an L-shaped frame 12, a second U-shaped frame 13 and a connecting rod 14. Among them, one end of the front frame body 11 is open and faces the first U-shaped frame 22; two L-shaped frames 12 are arranged at the open end of the front frame body 11; the second U-shaped frame 13 is connected to the two L-shaped frames 12; the connecting rod 14 is arranged on the second U-shaped frame 13 and is hinged to the swing arm 66;

[0093] In the above structure, for the rear frame body 21 in the second carrier 2 and the front frame body 11 in the first carrier 1, the opposite surfaces of both are set as open structures. The rear frame body 21 is connected with a first U-shaped frame 22, and the front frame body 11 installs the second U-shaped frame 13 through two L-shaped frames 12. In this way, when the first carrier 1 swings, the second U-shaped frame 13 will move to the inner side of the first U-shaped frame 22, thus avoiding interference problems. This structure makes the distance between the first carrier 1 and the second carrier as small as possible, improves the structural compactness of the first carrier 1 and the second carrier 2, and is also beneficial to reducing the load of the power component 6 during operation;

[0094] Among them, during driving, the swing arm 66 of the power component 6 drives the first carrier 1 to perform pitching swing adjustment through the connecting rod 14.

[0095] Such as Figure 4 As shown, the connecting piece 8 includes a lapping plate 81 and a connecting cable 82. Among them, the hydraulic cylinder 7 is arranged at one end of the first carrier 1 close to the second carrier 2, and the movable end of the hydraulic cylinder 7 is arranged downward; the lapping plate 81 is arranged at one end of the first carrier 1 close to the second carrier 2, and the lapping plate 81 lapps the second carrier 2; one end of the connecting cable 82 is connected to the first carrier 1, and the other end is connected to the second carrier 2;

[0096] In the above structure, in order to further reduce the load of the power component 6 and the connecting rod 14, at this time, the hydraulic cylinder 7 can be used for auxiliary support to ensure the structural stability of the first carrier 1; specifically, the cylinder body of the hydraulic cylinder 7 can be hinged to the first carrier 1;

[0097] In some embodiments, the second carrier 2 detaches from the first carrier 1. At this time, the first carrier 1 can be adjusted in angle independently by the hydraulic cylinder 7. However, considering the factors of adjustment convenience and efficiency, as well as the factor of support stability, it is preferably to keep the connection between the second carrier 2 and the first carrier 1 and adjust the first carrier 1 through the power component 6;

[0098] Among them, when the first carrier 1 and the second carrier 2 are level, the boarding plate 81 will be mounted on the second carrier 2 to bear the weight of the first carrier 1, thereby reducing the load on the power component 6 and improving the stability of the structure;

[0099] Among them, the connecting cable 82 is set as a detachable structure. In this way, when towing the first carrier 1 through the tractor head, the second carrier 2 can be towed through the connecting cable 82, and when the first carrier 1 needs to be adjusted, the connecting cable 82 can be removed.

[0100] As Figure 5 shown, the manifold assembly 5 includes a connecting member 51, a manifold 52 and a bracket 53. Among them, the connecting member 51 is connected to the first carrier 1, and the connecting member 51 is located at the bottom of the first carrier 1; the manifold 52 is arranged on both sides of the connecting member 51, and the manifold 52 is communicated with the connecting member 51; a plurality of brackets 53 are arranged on both sides of the first carrier 1 and correspond to the nozzles of the manifold 52, and the brackets 53 are detachably connected to the first carrier 1;

[0101] In the above structure, the manifold assembly 5 is used to connect the liquid outlet pipelines of several fracturing trucks. It has a plurality of mutually connected connecting members 51, and a manifold 52 is arranged on each connecting member 51

[0102] In the working chamber, it is connected to the liquid outlet pipeline of the fracturing truck through the manifold 52, and the fracturing fluid output by several fracturing trucks is collected through the connecting member 51 and can be output through one port;

[0103] Specifically, when assembling the manifold assembly 5, the connecting member 51 can be connected and fixed to the first carrier 1 through fasteners;

[0104] Among them, brackets 53 corresponding to the manifolds 52 are arranged on the first carrier 1, which are used to carry the automated connection pipelines. Some of the pipelines in the manifold assembly are composed of several sections of pipes connected movably, which have a high degree of adjustment freedom. At this time, they are driven by a hydraulic cylinder, and then the pipelines can be automatically docked with the liquid outlet of the fracturing truck;

[0105] In this structure, there is no need for the fracturing truck to connect to the manifold 52 through a flexible pipeline. Instead, an automated docking pipeline is arranged on the manifold 52 and supported by the bracket 53;

[0106] Specifically, the bracket 53 is provided as a detachable structure. When it is necessary for the fracturing truck to use a flexible pipeline to connect to the manifold 52, by disassembling the bracket 53, structural interference can be avoided.

[0107] As Figure 7 and Figure 8 As shown, the pipe support assembly 9 includes a pipe support 91 and a cleaning pipeline 92. Among them, the pipe support 91 is arranged on the first carrier 1, and a U-shaped notch 901 is formed on the pipe support 91 for supporting the functional pipeline 100; the cleaning pipeline 92 is slidably arranged on the first carrier 1 to position and clean the functional pipeline 100;

[0108] In the above structure, the pipe support 91 is arranged on the upper part of the first carrier 1, and a U-shaped notch 901 is formed on it for fixing the functional pipeline 100, thus making full use of the upper space of the first carrier 1 and improving the overall transport capacity;

[0109] At the same time, a cleaning pipeline 92 is arranged on the first carrier 1, which can clean the functional pipeline 100 to avoid the problem of foreign matter blockage in the functional pipeline 100, and realize the function of detecting and judging whether the functional pipeline 100 can normally circulate the medium; at the same time, it is also used to position the functional pipeline 100 to prevent the functional pipeline 100 from detaching from the pipe support 91;

[0110] Specifically, the functional pipeline 100 is used for the connection of equipment at the oil extraction site to realize the transportation of the medium, and it is not limited to the transportation of fracturing fluid.

[0111] As Figure 5 、 Figure 6 and Figure 8 As described above, the pipe support assembly 9 further includes a push rod 93. The cleaning pipeline 92 includes a support 921, a shaft pipe 922 and a spray pipe 923. Among them, the push rod 93 is arranged on the first carrier 1, and the movable end of the push rod 93 abuts against the functional pipeline 100; the support 921 is slidably arranged on the first carrier 1; the shaft pipe 922 is rotatably connected to the support 921; a plurality of spray pipes 923 are arranged on the shaft pipe 922, and multiple shaft pipes 922 are communicated with the shaft pipe 922;

[0112] In the above structure, in the cleaning pipeline 92, the shaft pipe 922 is used to connect the water supply structure, and then the functional pipeline 100 can be flushed through the spray pipe 923;

[0113] Among them, the shaft pipe 922 is rotatably connected to the support 921, and the support 921 is slidably connected to the first carrier 1. In this way, when positioning, the support 921 can drive the shaft pipe 922 and the spray pipe 923 to move towards the functional pipeline 100. After the spray pipe 923 is inserted into the shaft pipe 922, the end positioning of the shaft pipe 922 is realized, and the radial movement of the shaft pipe 922 can be avoided. At the same time, the shaft pipe 922 can be provided with a reduced-diameter section to abut against the pipe support 91, so as to realize axial positioning;

[0114] Specifically, the support 921 can be arranged on the first carrier 1 through moving components such as slide rails or guide wheels. Of course, the support 921 is provided with a corresponding positioning mechanism to connect to the first carrier 1, so as to selectively switch between being movable and fixed relative to the first carrier 1; for example, bolts are set as the positioning mechanism.

[0115] When the functional pipeline 100 needs to be unloaded, a lifting device is required. At this time, one end of the functional pipeline 100 can be positioned through the cleaning pipeline 92, and then the other end of the functional pipeline 100 is jacked up by the push rod 93. At this time, the functional pipeline 100, the shaft pipe 922 and the nozzle 923 rotate with the support 921 as the fulcrum, so that the functional pipeline 100 is separated from the U-shaped notch 901, thus facilitating the hoisting work and avoiding problems such as jamming and impact.

[0116] In this structure, the diameter of the nozzle 923 is slightly smaller than the inner diameter of the functional pipeline 100 to facilitate the separation of the functional pipeline 100 from the nozzle 923 during hoisting.

[0117] In this structure, during transportation, the functional pipeline 100 is assisted to be fixed to the pipe rack 91 through fasteners such as ropes.

[0118] Such as Figure 1 and Figure 3 As shown, the lifting device 10 is arranged on the second carrier 2; the lifting device 10 is used for component hoisting and serves as a counterweight.

[0119] In the above structure, the lifting device 10 is used for component hoisting to unload equipment such as the functional pipeline carried on the first carrier 1, and at the same time, it serves as a counterweight by itself to avoid the problem that the tail end of the second carrier 2 tilts up due to its own light weight when the power component 6 adjusts the attitude of the first carrier 1, thus ensuring the stability and convenience of the application.

[0120] The application method of the fracturing manifold truck of the present invention includes the following steps:

[0121] S1. Hoist the manifold assembly 5 through the first carrier 1 and carry engineering equipment on the first carrier 1.

[0122] S2. Connect the first carrier 1 with a tractor head to tow the first carrier 1 and the second carrier 2 to the construction site.

[0123] S3. The tractor head detaches from the first carrier 1, positions the first carrier 1, and unloads the engineering equipment on the first carrier 1.

[0124] S4. Drive the first carrier 1 to swing up and down with the front wheel set 3 as the axis through the power component 6 for leveling.

[0125] S5. Connect the liquid outlet pipeline of the fracturing truck to the manifold assembly 5 and conduct the hydraulic fracturing operation for exploitation;

[0126] S6. After the exploitation is completed, disconnect the connection between the liquid outlet pipe of the fracturing truck and the manifold assembly 5, and drive the first carrier 1 to swing through the power member 6 so that one end of the manifold assembly 5 is lifted up for evacuation;

[0127] S7. Re-load the engineering equipment onto the first carrier 1 and tow the first carrier 1 and the second carrier 2 through the tractor head.

[0128] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
