Description

Technical Field

[0001] The present invention relates to a mechanical device for oil and gas exploration and utilization, and specifically to an automatic placement device for wireless node instruments, belonging to the technical field of seismic exploration. Background Art

[0002] In the field of foreign automated placement, it is currently only known that the American company GTI owns a node placement device. After independently developing the node instrument NUSEIS, GTI manufactured a set of automatic placement equipment for the NUSEIS node instrument. It also adopts a towed structure, but in the design of the placement bin, a crawler movement mode is used. The bin is small and is directly above the drilling device, and the node instrument is sent into the hole by means of transmission.

[0003] In China, with the continuous deepening of exploration in the eastern region, in order to meet the needs of fine structural interpretation and reservoir description, and to solve the more concealed geological bodies of "thin, deep, small, and fragmented" in the old eastern areas, it is inevitable to further promote the application of single-point high-density technology. Compared with traditional wired seismic instruments, node instruments are easier to deploy, which is more conducive to the full promotion of this technology. Node instruments will surely be widely used in the eastern region. However, if a large number of nodes are still deployed manually, not only a large amount of manpower is required, which is not conducive to project cost management, but also the HSE control risk is increased. With the progress of science and technology, improving efficiency and saving labor costs is an inevitable development trend. Therefore, it is an urgent need to develop an automatic placement device for node instruments with high production efficiency. Summary of the Invention

The node instrument is installed between the loops of the spring before blanking. Limiting rods for restricting the rotation of the node instrument are arranged around the spring. At the same time, two limiting plates are installed inside the spring, and a vertical strip-shaped gap is left between the two limiting plates. For the loaded node instrument, the front end tail cone is located in the strip-shaped gap.

Specific embodiments

[0035] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] As Figures 1-3 , an embodiment provided by the present invention: a wireless node instrument automatic placement device, which includes a vehicle frame 1, and a silo 7, a drilling and feeding mechanism 8, and a blanking mechanism 9 provided on the vehicle frame 1; the silo 7 includes a central shaft 701, a plurality of small silos arranged around the central shaft 701, and rotating disks provided at both ends of the central shaft 701, and the rotating disks drive the small silos to rotate together. The node instrument 11 is placed in the small silo, and the node instrument 11 inside it falls successively from bottom to top, and the falling node instrument 11 falls into the feeding mechanism 9; the drilling and feeding mechanism 8 includes an auger bit 801, a drill 802, a first slide 803, a material receiving claw 804 and a conversion arm 805. The auger bit 801 is arranged at the front end of the drill 802, the drill 802 is installed on the first slide 803, and the first slide 803 drives the drill 802 to move up and down. The material receiving claw 804 is arranged at the front end of the conversion arm 805 and is used to catch the node instrument 11 falling from the small silo. After the drill bit 801 drills a hole at a specified point, the conversion arm 805 sends the material receiving claw 804 above the hole through a rotational movement; the blanking mechanism 9 includes a second slide 902, a blanking cylinder 901, a soil pressing and fixing plate 904 and a four-jaw pneumatic claw 905. The blanking cylinder 901 is installed on the second slide 902 through a mounting seat 903. The soil pressing and fixing plate 904 is installed at the top of the output shaft of the blanking cylinder 901. The four-jaw pneumatic claw 905 can automatically open and close, and is used to grab the node instrument 11 located on the material receiving claw 804 and put it into the hole. After the node instrument 11 is put into the hole, the blanking cylinder 901 controls the operation of the soil pressing and fixing plate 904 to fill and compact the hole with soil.

[0037] In this embodiment, wheels 5 are provided at the bottom of the frame 1, and a trailer drawbar 6 is provided at the front end. At the same time, a gasoline generator 10 serving as a power source and an RTK positioning device 4 for positioning are also installed on the frame 1. The entire set of equipment is towed forward by an external trailer. The automatic placement vehicle itself is powered by an independent gasoline generator, and its power system does not interfere with that of the trailer. During operation, first, the equipment is parked directly above the placement point through RTK positioning. The drilling mechanism starts to work and completes drilling at the specified point. The node instrument is conveyed to above the hole position through the feeding structure in the bin. The feeding mechanism grabs the node instrument and sends it into the pre-drilled hole, and then performs soil filling and compaction to complete the burial of the node instrument, thereby completing the entire placement operation.

[0038] As Figures 4-8 , the small bin includes a spring 704, a limit plate 705, a limit rod 706, and a stop bar 707. The upper end of the spring 704 is connected to a turntable 709, and the turntable 709 is rotatably installed on the upper rotating disk 702. The lower end of the spring 704 is close to the discharge port 713 of the lower rotating disk in the natural state, and the distance between the loops of the spring 704 is slightly smaller than the main body diameter of the node instrument in the natural state. The node instrument 11 is installed between the loops of the spring 704 before feeding. Limit rods 706 for restricting the rotation of the node instrument 11 are arranged around the spring 704. At the same time, two limit plates 705 are installed inside the spring 704. A vertical strip-shaped gap is left between the two limit plates 705. For the node instrument after loading, its front tail cone is located in the strip-shaped gap. The stop bar 707 is located above the outer end of the discharge port 713 and is used to block the tail end of the node instrument 11 before it falls, so that the tail end of the node instrument 11 faces upward and the tail cone faces downward when it falls.

[0039] Preferably in this embodiment, a driving groove is provided at the upper end of the turntable 709, and a motor 710 is provided above the driving groove. The motor 710 is installed on a mounting plate 712, and the mounting plate 712 is simultaneously connected to the output end of a lifting cylinder 711. The lifting cylinder 711 is fixed on the bracket. The lifting cylinder 711 drives the motor 710 to move up and down through the mounting plate 712, and the motor 710 achieves engagement and separation with the driving groove during the up and down movement. When the output shaft of the motor 710 engages with the driving groove, the motor can drive the turntable to rotate through the driving groove, and then drive the spring to rotate. Then, during the rotation of the spring, due to the action of the limit plate and the limit rod, the node instrument inside it will gradually move downward and then fall.

[0040] Preferably in this embodiment, an openable door panel is provided on the outside of the spring, and a buckle is provided on the door panel. When it is necessary to install the node instrument into the spring, the door panel can be opened for manual installation, and the door panel can be closed after installation.

[0041] Preferably, in this embodiment, the rotating disk includes an upper rotating disk 702 and a lower rotating disk 703. A plurality of arc-shaped notch grooves 714 are evenly formed on the outer peripheral edge of the lower rotating disk 703, and strip-shaped grooves 715 are evenly formed at the bottom. At the same time, a driving mechanism for driving its rotation is provided on one side of the lower rotating disk 703. The driving mechanism includes a driving motor, a driving disk 716, and a cylindrical driving convex block 718. The driving motor drives the driving disk 716 to rotate through a combination gear. A positioning wheel 717 with a notch is installed in the middle above the driving disk 716, and a cylindrical driving convex block 718 is installed on the edge side. A bearing is installed on the cylindrical driving convex block 718. During the rotation process, the positioning wheel 717 cooperates with the arc-shaped notch grooves 714, and the cylindrical driving convex block 718 and its bearing cooperate with the strip-shaped grooves 715 to drive the lower rotating disk to rotate, and then drive the entire silo to rotate.

[0042] As Figures 9-10 , in the punching and feeding mechanism, the first sliding table 803 and the conversion arm 805 are jointly installed on the same vertical shaft. The material receiving claw 804 is a U-shaped openable and closable structure, and concave teeth for positioning the node instrument 11 are provided inside its claw body.

[0043] As Figures 11-12 , in the blanking mechanism, the four-jaw pneumatic claw 905 is connected to the mounting seat 903 through a connecting rod 906, and the connecting rod 906 can movably pass through the top of the soil pressing and fixing disk 904. When the blanking cylinder 901 retracts, the soil pressing and fixing disk 904 rises, and the four-jaw pneumatic claw 905 extends out of the soil pressing and fixing disk 904. When the blanking cylinder 901 extends, the soil pressing and fixing disk 904 descends, and the four-jaw pneumatic claw 905 retracts into the soil pressing and fixing disk 904; in addition, helical teeth for facilitating soil cultivation and compaction are provided on the top circle of the soil pressing and fixing disk 904.

[0044] When the automatic laying device of this wireless node instrument is working, the punching and feeding mechanism and the blanking mechanism rotate around their respective central vertical shafts driven by motors respectively. The sequence of the whole set of actions is as follows: the punching mechanism first rotates to the designated position for punching, and then the conversion arm drives the feeding mechanism to rotate to the punching point. At this time, the blanking mechanism immediately rotates above the feeding mechanism to complete the blanking operation. During the blanking process, the sliding table can control the up and down translation of the entire cylinder, fixed disk and air claw. The cylinder controls the movement of the air claw and the fixed disk. The air claws are located inside the fixed disk and are connected to each other through connecting rods. After the node instrument is transported above the hole, the air claws firmly grasp the node instrument. The sliding table controls the entire blanking mechanism to move downwards. After slowly placing the node instrument into the hole, the air claws are released. At this time, the outer fixed disk presses down, and the soil pressing steel ring at the bottom is in full contact with the ground, and the surrounding soil is cultivated and compacted through the diagonal teeth to complete the laying. After the work is completed, the blanking mechanism first rotates back to the original position, and then the entire punching and feeding mechanism also returns to the initial position driven by the rotating arm. The feeding structure returns directly below the storage bin to prepare for the next blanking. Each device cooperates with each other without interference.

[0045] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those of ordinary skill in the art should understand that the above embodiments do not limit the protection scope of the present invention in any form. Any technical solutions obtained by means of equivalent replacement and the like fall within the protection scope of the present invention.
