DETAILED DESCRIPTION

[0016] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1-Figure 3As shown, the embodiment of the utility model proposes a Christmas tree wellhead device, including: a wellhead device body 1 and a frame 11. The frame 11 is a component installed around the wellhead device body 1 and fixed on the ground. A dustproof component can be added to the frame 11. The frame 11 is installed with a dustproof component. The dustproof component includes a notch 12 opened on the upper end surface of the frame 11. A sealing box 13 is slidably connected in the notch 12. The setting of the sealing box 13 can form a closed space for the wellhead device body 1 when it is not in a working state, thereby reducing the damage of environmental dust to the wellhead device body 1. The sealing box 13 is made of stainless steel. The anti-corrosion of the stainless steel material The airtight box 13 is resistant to corrosion, which can reduce the environmental corrosion suffered by the airtight box 13, thereby extending the service life of the device. The airtight box 13 is provided with two mutually symmetrical bayonet ports 14, and the slot 12 is provided with two mutually symmetrical sliding ports 15. The two sliding ports 15 are slidably connected with a card block 16, and one end of the two card blocks 16 is fixedly connected with a pull rod 17. The ends of the two pull rods 17 away from the frame 11 are both installed with a pull ring 21. Through the pull ring 21, the staff can easily pull the pull rod 17, so that the card block 16 leaves the bayonet port 14 to complete the installation and disassembly of the airtight box 13. The other ends of the two pull rods 17 penetrate the frame 11, and the two pull rods 17 are fixedly connected with the frame 11. Springs 18 are sleeved on the rods 17, one end of the two springs 18 is fixedly connected to the two blocks 16, and the other ends of the two springs 18 are fixedly connected to the two sliding openings 15. Through the above structure, when the staff pulls the pull ring 21, the pull rod 17 is driven to move backward, so that the block 16 leaves the bayonet 14. After release, the block 16 slides in the sliding opening 15 and re-enters the bayonet 14 through the rebound reset effect of the spring 18 to fix the sealed box 13. The four mutually symmetrical supporting and fixing components include an extension block 2 installed on the wellhead device body 1, and the extension block 2 is provided with a rotating opening 3. A rotating block 4 is rotatably connected in the opening 3, a sliding opening 5 is provided on the rotating block 4, a supporting block 6 is slidably connected in the sliding opening 5, and a pad 20 is rotatably connected to the end of the supporting block 6 away from the sliding opening 5, and a group of screw holes are provided on the pad 20, and the pad 20 can be adjusted following the rotation angle of the rotating block 4, so that it can always be stably fitted with the ground, and then the bolts are installed in the screw holes to fix the pad 20. Therefore, when working, the wellhead device body 1 can be placed more stably in the designated position for work, meeting the use needs of the staff, so that the supporting block 6 can be reinforced and the reinforcement work of the wellhead device body 1 is finally completed;One end of the support block 6 is threadedly connected with a threaded rod 7, and the other end of the threaded rod 7 is rotatably connected in the sliding port 5. One end of the threaded rod 7 is fixedly connected with an auxiliary gear 8. A rotating rod 9 is rotatably penetrated on the rotating block 4. A knob 19 is installed on the end of the rotating rod 9 away from the rotating block 4. By rotating the knob 19, the rotating rod 9 can be easily rotated to complete the adjustment of the support block 6. One end of the rotating rod 9 is fixedly connected with a driving gear 10, and the driving gear 10 is meshed with the auxiliary gear 8. Through the above structure, when the rotating rod 9 is rotated, the driving gear 10 can be driven to rotate, and the auxiliary gear 8 meshed with it can be driven to rotate through the driving gear 10, so that the threaded rod 7 fixedly connected to the auxiliary gear 8 rotates, and drives the support block 6 to slide in the sliding port 5 until it reaches the specified length, completing the support and fixing work of the wellhead device body 1, meeting the use needs of the staff. ;

[0018] When in use, the staff first places the wellhead device at the specified position, and then the staff starts to rotate the rotating block 4 in the rotating port 3. After reaching the specified angle, the knob 19 is rotated to drive the rotating rod 9 to rotate, so that the active gear 10 fixedly connected to the rotating rod 9 is rotated, and the rotation of the active gear 10 drives the auxiliary gear 8 meshing therewith to rotate. The rotation of the auxiliary gear 8 can make the threaded rod 7 fixedly connected to the auxiliary gear 8 rotate. When the threaded rod 7 rotates, the support block 6 threadedly connected thereto slides in the sliding port 5 until it is extended to the specified length to complete the adjustment of the support block 6. Then the staff rotates the pad 20 to make it parallel to the ground and fit it to the ground, and then uses the bolt to rotate it in. The pad 20 is fixed in the screw hole. At this time, the staff has completed the partial support and fixing work of the wellhead device body 1, and then the staff repeats the above operation to complete the fixed support of the wellhead device body 1, so as to make it more stable in the working state. After the work is completed, the staff takes out the sealed box 13 and pulls the pull ring 21 on the frame 11, aligns the sealed box 13 with the slot 12 and pushes it in, and releases the pull ring 21. Under the rebound and reset action of the spring 18, the block 16 slides in the sliding port 15, and then enters into the bayonet 14 to complete the installation of the sealed box 13. At this time, the wellhead device body 1 is sealed by the sealed box 13, which reduces the influence of dust in the environment on it, prolongs the service life of the device, and meets the use needs of the staff.
