Description

Technical Field

[0001] This utility model relates to the field of drilling gates, and more particularly to a drilling combined gate. Background Technology

[0002] Currently, in the oil drilling industry, drilling gates are the core equipment for guiding drilling fluid and are used to circulate drilling fluid. Using drilling gates can ensure the continuity and efficiency of drilling operations, and precisely control the flow direction of drilling fluid to ensure the stability and safety of the drilling process.

[0003] Currently, traditional drilling combination gate valves mainly consist of the gate valve and its installation structure. They are generally installed at the connection between two drilling channels, or at the end or head of the drilling channel. Compared with existing ordinary gate valves, drilling gate valves are specifically designed for drilling channels and are mostly similar in structure to the drilling channels. They can control the flow of drilling fluid.

[0004] However, most existing drilling gates are single-piece designs, which can only control one type of drilling fluid and cannot control the flow of drilling fluid in combination. As a result, the gates are easily damaged during long-term use. Utility Model Content

[0005] To overcome the problem that most existing drilling gates are one-piece designs, which can only perform one type of drilling fluid control and cannot control the flow of drilling fluid in a combined manner, and that the gates are easily damaged during long-term use.

[0006] The technical solution of this utility model is as follows: a drilling combined gate includes a gate installation channel, a support platform fixedly installed at the lower end of the gate installation channel, a fixed platform fixedly installed at the upper end of the gate installation channel, fixed brackets fixedly installed on both sides of the support platform and the fixed platform, a liftable gate body installed on the fixed platform and the gate installation channel, a motor box fixedly installed at the upper end of the gate body, a drive motor installed inside the motor box, a gate arm fixedly connected to the output end of the drive motor, a rotating plate fixedly connected to the lower end face of the gate arm, a fixed frame connected to the gate installation channel on the outer side of the rotating plate, a filter plate detachably installed inside the fixed frame, and filter holes evenly distributed on the surface of the filter plate.

[0007] Preferably, the opening and closing of the entire gate installation channel can be controlled by moving the gate body up and down, thereby controlling the overall height of the gate body and the rotating plate, and further controlling the flow rate of the drilling fluid. In addition, after the drive motor starts, it drives the gate arm to rotate, thereby driving the rotating plate to rotate, which can control the flow and flow rate of the drilling fluid without raising the gate body.

[0008] Preferably, the outer surface of the filter plate is fixedly mounted with evenly distributed mounting blocks, and the mounting blocks are detachably mounted with fixing bolts. The surfaces of the mounting blocks and the fixing frame are provided with mounting holes corresponding to the fixing bolts.

[0009] Preferably, a retaining frame is fixedly installed on the outside of the gate body, and connecting blocks corresponding to the fixed brackets are fixedly connected to both sides of the retaining frame.

[0010] Preferably, a connecting rod is fixedly installed on the upper end of the connecting block, and an electric cylinder is fixedly installed on the top of the fixed bracket, with the movable end of the electric cylinder fixedly installed on the upper end face of the connecting rod.

[0011] Preferably, the inner side of the fixed bracket is provided with a groove corresponding to the connecting block.

[0012] Preferably, a stiffening plate is fixedly installed on the upper end of the baffle frame, and the stiffening plate is fixedly installed on both sides of the gate body.

[0013] Preferably, the lower end of the gate body is provided with a groove corresponding to the rotating plate, and the upper surface of the rotating plate is fixedly connected to both sides with locking blocks, and the top of the groove is provided with locking holes corresponding to the locking blocks.

[0014] The beneficial effects of this utility model are:

[0015] 1. This drilling combined gate, by setting up a gate body, drive motor, gate arm and rotating plate, can control the opening and closing of the entire gate installation channel by moving the gate body up and down, thereby controlling the overall height of the gate body and rotating plate, and further controlling the flow rate of drilling fluid. In addition, after the drive motor starts, it drives the gate arm to rotate, thereby driving the rotating plate to rotate. The flow and flow rate of drilling fluid can be controlled without raising the gate body, realizing a combined drilling fluid dual control mode, reducing the risk of damage to a single gate opening and closing method due to long-term operation;

[0016] 2. This drilling combination gate, by setting a fixed frame and filter plate, can be used to filter drilling fluid, preventing too many impurities from entering the gate installation channel during the flow of drilling fluid, making the entire gate more durable. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-5 This utility model provides an embodiment: a drilling combined gate, including a gate installation channel 1, a support platform 2 fixedly installed at the lower end of the gate installation channel 1, a fixed platform 3 fixedly installed at the upper end of the gate installation channel 1, fixed brackets 4 fixedly installed on both sides of the support platform 2 and the fixed platform 3, a liftable gate body 5 installed on the fixed platform 3 and the gate installation channel 1, a motor box 6 fixedly installed at the upper end of the gate body 5, a drive motor 61 disposed inside the motor box 6, and the output end of the drive motor 61 fixedly connected to... A gate arm is fixedly connected to a rotating plate 13 at its lower end. After the drive motor 61 starts, it drives the gate arm to rotate, thereby driving the rotating plate 13 to rotate. This allows the flow and velocity of drilling fluid to be controlled without the gate body 5 rising. A fixed frame 7 connected to the gate installation channel 1 is provided on the outer side of the rotating plate 13. A filter plate 8 is detachably installed inside the fixed frame 7. The surface of the filter plate 8 has evenly distributed filter holes 81. The filter plate 8 can be used to filter impurities in the drilling fluid and prevent impurities from entering the gate installation channel 1.

[0025] Please see Figures 2-4The outer surface of the filter plate 8 is fixedly equipped with evenly distributed mounting blocks 82. Fixing bolts 83 are detachably mounted on the outside of the mounting blocks 82. Mounting holes corresponding to the fixing bolts 83 are opened on the surfaces of the mounting blocks 82 and the fixing frame 7. A baffle frame 12 is fixedly mounted on the outside of the gate body 5. Connecting blocks 9 corresponding to the fixing bracket 4 are fixedly connected to both sides of the baffle frame 12. A connecting rod 10 is fixedly mounted on the upper end of the connecting block 9. An electric cylinder 11 is fixedly mounted on the top of the fixing bracket 4. The movable end of the electric cylinder 11 is fixedly mounted on the upper end face of the connecting rod 10. The electric cylinder 11 can drive the connecting rod 10 to move upward or downward, thereby changing the position of the gate body 5. When the gate body 5 rises to a certain height, the gate installation channel 1 is fully opened, allowing the drilling fluid to flow normally. The inner side of the fixed bracket 4 is provided with a sliding groove corresponding to the connecting block 9. The upper end of the baffle 12 is fixedly installed with a stiffening plate 121, and the stiffening plate 121 is fixedly installed on both sides of the gate body 5. The lower end of the gate body 5 is provided with a groove 51 corresponding to the rotating plate 13. The upper surface of the rotating plate 13 is fixedly connected with two blocks. The top of the groove 51 is provided with a locking hole corresponding to the locking block. Through the mutual cooperation between the locking hole and the locking block, the rotating plate 13 can be firmly fixed on the gate body 5, preventing the rotating plate 13 from being pushed and rotated by external force.

[0026] During operation, the entire gate installation channel 1 is first installed in the drilling channel, with the side of the gate installation channel 1 containing the filter plate 8 installed at the drilling fluid inlet. The external fixing bracket 4 of the gate installation channel 1 is installed outside the drilling, so that the entire device is firmly fixed to the drilling. When it is necessary to control the drilling fluid, either the gate body 5 or the rotating plate 13 can be selected. When the gate body 5 is selected, the electric cylinder 11 can be opened first. The electric cylinder 11 can drive the connecting rod 10 to move upward, thereby changing the height of the gate body 5. When the gate body 5 rises to a certain height, the gate installation channel 1 is fully opened, allowing the drilling fluid to flow normally. When the rotating plate 13 is selected, the electric cylinder 11 can be left unopened, and the drive motor 61 can be turned on directly. After the drive motor 61 starts, it drives the gate arm to rotate, thereby driving the rotating plate 13 to rotate. The flow and velocity of the drilling fluid can be controlled without the gate body 5 rising.

[0027] Through the above steps, by setting up the gate body 5, drive motor 61, gate arm, and rotating plate 13, the opening and closing of the entire gate installation channel 1 can be controlled by moving the gate body 5 up and down, thereby controlling the overall height of the gate body 5 and the rotating plate 13, and further controlling the flow rate of drilling fluid. In addition, after the drive motor 61 starts, it drives the gate arm to rotate, thereby driving the rotating plate 13 to rotate. The flow and flow rate of drilling fluid can be controlled without raising the gate body 5, realizing a combined dual control mode for drilling fluid. This solves the problem that most existing drilling gates are integrated and can only complete one drilling fluid control mode, and cannot combine to control the flow of drilling fluid. In the long-term use, the gate is easily damaged.
