[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] In the description of the present invention, it should be noted that the terminology nouns in the various embodiments, such as words indicating directions such as "upper", "lower", "front", and "back", are only for simplifying the description of the positional relationship based on the drawings in the specification, and do not mean that the referred elements and devices must be operated according to the specific directions and defined operations and methods and structures in the specification. Such directional nouns do not constitute limitations to the present invention.

[0026] like Figure 1 , 2As shown, an embodiment of the present invention provides a manifold device, including a manifold 1, a folding arm assembly 2 and a mounting platform 3, wherein the manifold 1 is arranged on the mounting platform 3, and the folding arm assembly 2 is arranged on the manifold 1 or the mounting platform 3, and the manifold device also includes a rotary joint 12 and a plurality of connecting pipes 13, wherein one of the connecting pipes 13 is connected to the manifold 1, and adjacent connecting pipes 13 are connected via the rotary joint 12; the folding arm assembly 2 includes a plurality of folding arm units 21, adjacent folding arm units 21 are rotatably connected, and at least one connecting pipe 13 is arranged on each of the folding arm units 21.

[0027] In this embodiment, the mounting platform 3 can be a skid frame or a work vehicle with a chassis. Preferably, for the convenience of transportation, the mounting platform 3 is a work vehicle with a chassis, and the work vehicle is provided with four hydraulic support legs to achieve support during the working process. Among them, the manifold 1 is arranged on the mounting platform 3, and the connection method refers to the structure on the existing manifold 1 vehicle and the manifold 1 skid, so it is not repeated here. In one embodiment, the folding arm assembly 2 is arranged on the manifold 1, specifically, the manifold 1 is provided with a first connecting seat, and the folding arm assembly 2 is fixed on the first connecting seat. In another embodiment, the folding arm assembly 2 is arranged on the chassis of the work vehicle, specifically, the chassis is provided with a second connecting seat, and the folding arm assembly 2 is fixed on the second connecting seat. The above two embodiments of the folding arm assembly 2 are determined according to actual needs. When the chassis of the skid frame or the work vehicle has sufficient installation space, the folding arm assembly 2 is arranged on the skid frame or the chassis. When the skid frame or the chassis of the work vehicle does not have space for installing the folding arm assembly 2, the folding arm assembly 2 is arranged on the manifold 1. Based on this, the present application can also be improved on the existing manifold 1 vehicle and the manifold 1 skid, by setting the folding arm assembly 2 on the manifold 1 of the manifold 1 vehicle and the manifold 1 skid, and synchronously setting the connecting pipe 13 and the rotating joint 12 to cooperate with the folding arm assembly 2, thereby facilitating the improvement of old equipment and greatly saving costs.

[0028] In this embodiment, when the manifold equipment is working, it needs to transport fracturing fluid to the wellhead device of the oil well, which has a certain pressure. Therefore, the manifold 1 is a high-pressure manifold 1, and the connecting pipe 13 uses a large-diameter high-pressure pipeline, thereby reducing the wear group when the liquid flows. In other working environments, if the manifold equipment only transports liquids and does not need to provide a large pressure, the manifold 1 can be a low-pressure manifold 1, thereby reducing costs. Alternatively, the manifold 1 includes both a low-pressure manifold 1 and a high-pressure manifold 1, so that the high-pressure manifold 1 or the low-pressure manifold 1 can be selected according to needs, which is more versatile.

[0029] After adopting the manifold equipment of this embodiment, the manifold 1 and the folding arm assembly 2 are integrated on the installation platform 3, which is convenient for transportation and saves preparation time before installation; adjacent connecting pipes 13 are connected by a rotating joint 12; adjacent folding arm units 21 are rotatably connected, and at least one connecting pipe 13 is arranged on each folding arm unit 21; during the installation process, multiple folding arm units 21 are extended, which can quickly align the connecting pipe 13 with the wellhead device of the oil well, thereby facilitating the installation of the connecting pipe 13 and the wellhead device of the oil well. Compared with the existing arrangement of connecting the manifold 1 with the wellhead device of the oil well according to the on-site environment, the present invention enhances the versatility of the manifold 1, and under the action of the folding arm frame, it can adapt to different on-site environments without the need for re-disassembly and assembly, thereby improving the installation efficiency of the manifold 1 and the wellhead device of the oil well.

[0030] like Figure 1 As shown, a plurality of the folding arm units 21 constitute a folding arm group, and the folding arm assembly 2 also includes a rotating mechanism 22, which is arranged on the manifold 1 or the mounting platform 3, and the rotating mechanism 22 is drivingly connected to the folding arm group, and the rotating mechanism 22 is suitable for driving the folding arm group to rotate around the central axis of the rotating mechanism 22.

[0031] Specifically, multiple folding arms are rotated and connected in sequence to form a folding arm group. The number of folding arms is not limited and is determined according to actual conditions. The folding arms are prior art and are folded by hydraulic drive. Figure 1 As shown, there are three folding arms, which are rotatably connected and rotate with each other through a hydraulic cylinder. The folding arm assembly 2 also includes a slewing mechanism 22, which is arranged on the manifold 1 or the mounting platform 3, and is drivingly connected to the folding arm group. The slewing mechanism 22 is suitable for driving the folding arm group to rotate around the central axis of the slewing mechanism 22.

[0032] In this way, under the action of the swivel mechanism 22, the folding arm group can be rotated 360 degrees, so as to adjust the position of the connecting pipe 13 according to the on-site conditions. It should be understood that a rotating elbow is required to cooperate with the folding arm group to rotate around the central axis of the swivel mechanism 22.

[0033] Optionally, the manifold 1 includes a manifold body 11 , which is disposed on the mounting platform 3 , and the manifold body 11 is provided with a plurality of liquid outlets, at least one of which is connected to the connecting pipe 13 via the rotary joint 12 .

[0034] like Figure 1 As shown, the manifold body 11 is arranged on the chassis of the work vehicle, and the manifold body 11 is provided with a plurality of liquid outlets. Specifically, the left and right sides of the manifold body 11 are provided with a plurality of liquid outlets, and one liquid outlet and the connecting pipe 13 are connected through a rotating joint 12.

[0035] With such arrangement, the manifold 1 can deliver high-pressure liquid to the wellhead device of the oil well, and can also meet the requirement of simultaneously inputting high-pressure liquid to multiple fracturing vehicles.

[0036] like Figure 3 As shown, it also includes a connecting component 4, the connecting tube 13 and the folding arm unit 21 are connected through the connecting component 4, the connecting component 4 includes a first connecting member 41, a second connecting member 42 and a fastener 43, one end of the first connecting member 41 and one end of the second connecting member 42 are respectively movably connected to the folding arm unit 21, the other end of the first connecting member 41 and the other end of the second connecting member 42 are suitable for being connected through the fastener 43, and the connecting tube 13 is suitable for being clamped between the first connecting member 41 and the second connecting member 42.

[0037] In one embodiment, the first connecting member 41 and the second connecting member 42 are of an "Ω" shape, and the first connecting member 41 and the second connecting member 42 are a three-section plate structure, that is, the first connecting member 41 and the second connecting member 42 both include an arc-shaped plate and a first connecting plate and a second connecting plate arranged at both ends of the arc-shaped plate, and an ear seat is provided on the folding arm, and the first connecting plate and the ear seat are rotatably connected. Specifically, the ear seat is provided with a mounting groove, and a part of the first connecting plate is extended into the mounting groove and is rotatably connected to the ear seat through a pin shaft; after the second connecting plate of the first connecting member 41 and the second connecting plate of the second connecting member 42 are connected through a fastener 43, the connecting tube 13 is clamped between the first connecting member 41 and the second connecting member 42, specifically, the connecting tube 13 is clamped between the two arc-shaped plates, and the inner wall of the arc-shaped plate is matched with the outer wall of the connecting tube 13, thereby increasing the contact area between the arc-shaped plate and the connecting tube 13, thereby more firmly clamping the connecting tube 13.

[0038] Optionally, the first connecting member 41 is provided with a first hole structure 411 , the second connecting member 42 is provided with a second hole structure 421 , and the fastener 43 is passed through the first hole structure 411 and the second hole structure 421 to connect the first connecting member 41 and the second connecting member 42 .

[0039] like Figure 3 , 4 As shown in Figure 5, the fastener 43 is a bolt. The first connecting plate of the first connecting member 41 is provided with a penetrating first hole structure 411, and the second connecting plate of the second connecting member 42 is provided with a penetrating second hole structure 421. When the first hole structure 411 and the second hole structure 421 are aligned, the bolt is passed through the first hole structure 411 and the second hole structure 421 to connect the first connecting member 41 and the second connecting member 42, thereby finally achieving the fastening of the first connecting member 41 and the second connecting member 42.

[0040] In other embodiments of the connection component 4, the connection component 4 is a cable tie or a cable rope, and the connection tube 13 is fixed to the folding arm by the cable tie or the cable rope.

[0041] Optionally, a camera assembly 5 is further included, and the camera assembly 5 is arranged at the connection between two adjacent connecting tubes 13 to obtain image information of the connection between the two adjacent connecting tubes 13 .

[0042] In this embodiment, the camera assembly 5 is arranged at the connection between two adjacent connecting tubes 13 to obtain image information of the connection between the two adjacent connecting tubes 13. Specifically, the camera assembly 5 includes a camera 51, and the camera 51 is arranged on the connecting tube 13 or the folding arm unit 21, and the lens of the camera 51 is facing the connection between the two adjacent connecting tubes 13.

[0043] In this embodiment, the camera 51 is arranged on the connecting tube 13 or on the folding arm. When the camera 51 is arranged on the connecting tube 13, it is more convenient to obtain image information of the adjacent connecting tubes 13 at the connection point, and the camera 51 is arranged on the connecting tube 13. When the camera 51 is arranged on the folding arm, it is more convenient to obtain image information of the adjacent connecting tubes 13 at the connection point, and the camera 51 is arranged on the folding arm. The lens of the camera 51 faces the connection point of the two adjacent connecting tubes 13. In order to facilitate the observation of whether there is leakage in the adjacent connecting tubes 13, the camera 51 obtains image information of the connection point of the two adjacent connecting tubes 13 from below.

[0044] like Figure 6 As shown, the camera assembly 5 also includes a clamping member 52 and a mounting seat 53, the clamping member 52 is suitable for clamping the connecting tube 13 or the folding arm unit 21, the mounting seat 53 is movably connected to the clamping member 52, and the mounting seat 53 is movably connected to the camera 51.

[0045] In this embodiment, the clamping member 52 includes an elastic clip 521 and a connecting rod 522 connected to each other. When the elastic clip 521 clamps the connecting tube 13, the opening size of the elastic clip 521 is set according to the diameter of the connecting tube 13. When the elastic clip 521 needs to cooperate with the folding arm, an auxiliary tube is welded at the corresponding position of the folding arm for the elastic clip 521 to clamp. At the same time, the auxiliary tube is consistent with the size of the connecting tube 13. One end of the connecting rod 522 is connected to the elastic clip 521, and the other end of the connecting rod 522 is provided with a ball head. The mounting seat 53 is provided with a first mounting groove that cooperates with the ball head. The connecting rod 522 is ball-connected with the mounting seat 53 through the ball head and the first mounting groove. The mounting seat 53 is provided with a second mounting groove, and the camera 51 is rotatably arranged in the second mounting groove through a rotating shaft.

[0046] With such arrangement, during installation, the camera assembly 5 can be fixed in place by the elastic clip 521 , and since the mounting seat 53 is movably connected to the clamping member 52 , the mounting seat 53 and the camera 51 are movably connected, the position of the camera 51 can be adjusted to adjust the shooting range of the camera 51 .

[0047] Optionally, it also includes a first driving device 6 and a second driving device 7, wherein the first driving device 6 is drivingly connected to the mounting seat 53, and the first driving device 6 is suitable for driving the mounting seat 53 to rotate relative to the clamping member 52, and the second driving device 7 is drivingly connected to the camera 51, and the second driving device 7 is suitable for driving the camera 51 to rotate relative to the mounting seat 53.

[0048] In this embodiment, the first driving device 6 is connected to the mounting seat 53 by driving, and the first driving device 6 is suitable for driving the mounting seat 53 to rotate relative to the clamping member 52. Specifically, the first driving device 6 is an electric cylinder, which is arranged on the clamping member 52. Specifically, one end of the electric cylinder is connected to the connecting rod 522 by rotation, and the other end of the electric cylinder is connected to the mounting seat 53 by rotation. The electric cylinder is extended and retracted, so that the mounting seat 53 can rotate relative to the clamping member 52. The second driving device 7 is connected to the camera 51 by driving, and the second driving device 7 is suitable for driving the camera 51 to rotate relative to the mounting seat 53. Specifically, the second driving device 7 is a motor, which is arranged on the mounting seat 53, and the rotation axis of the motor is connected to the rotation axis of the camera 51 by driving. When the motor is working, the rotation of the motor drives the rotation axis of the camera 51 to rotate, so as to realize the rotation of the camera 51 relative to the mounting seat 53. And the rotation direction of the mounting seat 53 relative to the clamping member 52 is different from the rotation direction of the camera 51 relative to the mounting seat 53.

[0049] With such arrangement, when the camera 51 has a poor imaging range, the position of the camera 51 can be adjusted through the cooperation of the first driving device 6 and the second driving device 7, thereby facilitating accurate acquisition of image information of the connection between two adjacent connecting pipes 13.

[0050] Optionally, it also includes a controller 8 and an alarm 9, wherein the controller 8 is electrically connected to the camera 51 and the alarm 9 respectively, and the controller 8 is used to receive image information transmitted by the camera 51 and control the working state of the alarm 9 according to the image information.

[0051] In this embodiment, the camera 51 is used to obtain image information of two adjacent connecting pipes 13 at the connection point, and the alarm 9 is used to issue an audible and visual alarm. The controller 8 is electrically connected to the camera 51 and the alarm 9 respectively, and the controller 8 is used to receive the image information transmitted by the camera 51. The controller 8 is also used to conduct or cut off the circuit at the alarm 9. In one embodiment, when the controller 8 monitors that there is a leakage in the image transmitted by the camera 51, the controller 8 conducts the circuit of the alarm 9, and the alarm 9 issues an audible and visual alarm.

[0052] In this embodiment, the controller 8 is used to divide the image into a first area, a second area and a third area after acquiring the image information. The first area contains the image information of the connection between the rotary joint 12 and one of the connecting tubes 13, the second area contains the image information of the rotation of the rotary joint 12, and the third area contains the image information of the connection between the rotary joint 12 and another connecting tube 13. According to the priority order set for the first area, the second area and the third area, the image information in the first area, the second area and the third area are compared with the preset image information. If at least one of the image information in the first area, the second area and the third area meets the preset conditions, an alarm is issued. In this way, the image is divided into areas for comparison, and the result obtained is more reliable, avoiding too many misjudgments.

[0053] In this embodiment, the liquid flows from the connecting tube 13 in the first area to the connecting tube 13 in the second area. Since the rotary joint 12 performs a rotational motion at the rotating part, the possibility of leakage is the greatest. The liquid first flows through the connecting tube 13 in the first area, and the possibility of leakage is second. The liquid finally flows through the connecting tube 13 in the third area, and the possibility of leakage is the lowest. Therefore, the priority order set for the first area, the second area, and the third area is: the second area> the first area> the third area. Therefore, when performing graphic information comparison, the image information of the second area is compared first, then the image information of the first area, and finally the image information of the third area. With such a setting, it is convenient to detect leakage as quickly as possible while reducing the computing load.

[0054] In this embodiment, the preset condition means that there is leakage when the acquired image information is compared with the pre-stored image information. When the image information in the first area, the second area and the third area is compared with the preset image information, if one is found not to meet the preset condition, there is no need to perform the unfinished comparison. For example, when it is found that the image information in the second area meets the preset condition, an alarm is directly issued, and the subsequent comparison of the image information in the first area and the third area with the preset image information is no longer performed. This setting reduces the load on the system operation.

[0055] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
