Technical Field

[0001] The utility model relates to the technical field of jam-releasing and salvaging equipment, in particular to a pressure-boosting jam-releasing device. Background Art

[0002] In recent years, with the rapid development of my country's economy and the continuous decline of oil and gas field development and non-renewable resources, in order to alleviate the situation of excessive dependence on imports of oil and gas resources in my country, major domestic oil fields have accelerated the exploration and development of oil and gas resources.

[0003] At present, the existing pressure-boosting jam releasers on the market may encounter the problem of difficulty in jamming during actual operation. The further method is to increase the force and rise the rod inside the cavity through hydraulic pressure or rotation, so as to achieve the effect of pulling out the jam. However, if it encounters blockage or gets stuck in the structure during operation and cannot rise, it will affect the overall jam release effect. Utility Model Content

[0009] As a preferred technical solution of the utility model, the bottom end of the push rod is fixedly connected with a clamping column, the bottom end of the clamping column is fixedly connected with a positioning column, and the bottom end of the positioning column is in contact with the top end of the support plate.

[0010] As a preferred technical solution of the utility model, limit rods are arranged on both sides away from the spring column, the limit rods are compression type, and the two ends of the limit rods are respectively arranged on the top support member and the bottom of the support plate.

[0011] Compared with the prior art, the beneficial effect of the utility model lies in that: by connecting the seals on both sides of the support plate at the top of the spring column and driving the seals up and down through the hydraulic rod, the position of the seals can float up and down, thereby completing the effect of closing or separating with the flow ports on both sides of the cavity, thereby achieving the purpose of unblocking.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0017] Reference Figure 1-2 A pressure booster card release device comprises a cavity 1, a pressure relief channel 2 is arranged in the cavity 1, the top of the inner part of the pressure relief channel 2 is movably connected to a hydraulic rod 3, the bottom end of the hydraulic rod 3 is fixedly connected to a push rod 4, and the push rod 4 is located at the central axis of the pressure relief channel 2; flow ports 10 are opened on both sides of the bottom of the pressure relief channel 2, an extrusion component is arranged at the bottom end of the pressure relief channel 2, and sealing members 9 are connected on both sides of the extrusion component, and the sealing members 9 can correspond to the flow ports 10, and the flow ports 10 are closed or opened by the sealing members 9 moving up and down.

[0018] The extrusion component includes a support member 7, which is installed at the inner bottom end of the pressure relief channel 2. The top of the support member 7 is connected to a spring column 8. A reset rod is fixedly installed in the middle of the spring column 8. When the hydraulic rod 3 is lifted to a certain position, the spring column 8 is not subjected to the force of the hydraulic rod 3. At this time, the reset rod drives the spring column 8 to rise and return to its original state.

[0019] The top end of the spring column 8 is fixedly connected with a support plate, both sides of the support plate are fixed to the side walls of the two sealing members 9, and limiting openings are provided on both sides of the top of the support plate.

[0020] The bottom end of the push rod 4 is fixedly connected with a clamping column 5, the bottom end of the clamping column 5 is fixedly connected with a positioning column 6, and the bottom end of the positioning column 6 is in contact with the top end of the support plate.

[0021] Limit rods 11 are arranged on both sides away from the spring column 8. The limit rods 11 are compression type. The two ends of the limit rods 11 are respectively arranged on the top support member 7 and the bottom of the support plate. The limit rods 11 are used to limit the stability when the spring column 8 is squeezed.

[0022] When in use, the hydraulic rod 3 can be connected to an external hydraulic component. The push rod 4 inside the pressure relief channel 2 is driven to move by squeezing the hydraulic rod 3. Since the bottom of the push rod 4 is respectively connected to the clamping column 5 and the positioning column 6, the spring column 8 is squeezed as the whole descends, causing the spring column 8 to be pressed downward. At this time, the sealing members 9 located on both sides of the top of the spring column 8 reach the position of the flow port 10, thereby achieving the effect of closing or opening the flow port 10, thereby completing the force-enhancing card-releasing process.
