DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0022] Example 1

[0023] A natural gas valve well cover automatic opening device, such as Figure 1-Figure 5As shown, it includes a frame 1, a first hydraulic rod 2, a mounting frame 3, a guide rod 4, a sliding frame 5, a mounting frame 6 and a universal wheel 17. The bottom of the frame 1 is rotatably connected to the universal wheel 17 to facilitate the movement of the frame 1. The first hydraulic rod 2 is installed inside the frame 1, and the telescopic end of the first hydraulic rod 2 is connected to the mounting frame 3. The mounting frame 3 is connected with the guide rod 4 to play a guiding role. The sliding frame 5 is slidably connected to the guide rod 4. The number of the sliding frames 5 is not less than two. The bottom of the sliding frame 5 is installed with a mounting frame 6, and the mounting frame 6 is symmetrically provided with a slide groove 601. It also includes a second hydraulic rod 7, a connecting frame 8, a rotating plate 9, a support plate 10 and a slider 11. The second hydraulic rod 7 is installed inside the sliding frame 5, and the telescopic end of the second hydraulic rod 7 is connected to the connecting frame 8. The connecting frame 8 is symmetrically hinged with a rotating plate 9, and the other side of the rotating plate 9 is rotatably connected to the support plate 10. The outer side of the support plate 10 is symmetrically connected with a slider 11, and the slider 11 is slidably connected to the slide groove 601, and the support plate 10 drives the slider 11 to move.

[0024] like Figure 2 , Figure 3 and Figure 6 As shown, it also includes a partition 301, a mounting plate 12, a sliding rod 13, a block 14, a spring 15 and a connecting rod 16. Several partitions 301 are connected inside the mounting frame 3, and the mounting plates 12 are symmetrically installed on the outside of the sliding frame 5. The sliding rod 13 is slidably connected to the mounting plate 12. The top of the sliding rod 13 is connected to the block 14. The size of the block 14 is consistent with the size between the two partitions 301, which limits the sliding frame 5. A spring 15 is wound around the sliding rod 13, and the two ends of the spring 15 are respectively connected to the block 14 and the mounting plate 12. A connecting rod 16 is connected between the bottoms of the two sliding rods 13. The operator pulls the connecting rod 16 to drive the sliding rod 13 to move.

[0025] When the device is needed and the natural gas valve well needs to be opened, the operator first pushes the device above the natural gas valve well, and the four universal wheels 17 do not contact the natural gas valve well cover, and then pulls the two connecting rods 16 to move downward, and the movement of the connecting rod 16 drives the sliding rod 13 and the block 14 to move downward along the mounting plate 12, and the spring 15 is compressed. During the movement of the block 14, the block 14 is out of contact with the position between the two partitions 301, and then the sliding frame 5 is pulled along the guide rod 4 and moves according to the position of the wellbore. When the sliding frame 5 moves to above the wellbore position, the sliding frame 5 is no longer pulled, and the operator releases the connecting rod 16 again. Under the reset of the spring 15, the block 14 drives the sliding rod 13 to move upward along the mounting plate 12. During the movement of the block 14, the block 14 is in contact with the position between the two partitions 301 and is limited by it, and it is convenient to limit the sliding frame 5, and then start the first liquid The pressure rod 2, the telescopic end of the first hydraulic rod 2 drives the mounting frame 3, the guide rod 4, the sliding frame 5 and the mounting frame 6 to move downward. When the mounting frame 6 moves into the wellbore, the first hydraulic rod 2 is closed, and the operator starts the second hydraulic rod 7 again. The telescopic end of the second hydraulic rod 7 drives the connecting frame 8 to move downward, and the connecting frame 8 drives the rotating plate 9 to move downward. During the movement of the rotating plate 9, the rotating plate 9 rotates along the connecting frame 8, so that the support plate 10 moves outward along the mounting frame 6. While the support plate 10 moves, the support plate 10 drives the sliding block 11 to move outward along the sliding groove 601, so as to facilitate the jamming of the well cover. When the well cover is jammed, the second hydraulic rod 7 is closed, and the operator starts the first hydraulic rod 2 again. The first hydraulic rod 2 drives the mounting frame 3 and the guide rod 4 to move upward, and the guide rod 4 drives the sliding frame 5, the mounting frame 6 and the well cover to move upward, so as to facilitate the opening of the well cover. After the well cover is opened, the first hydraulic rod 2 can be closed.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
