[0020] This utility model provides a hydraulic buffer support for preventing crushing of downhole equipment. Compared with the prior art, it has the following advantages:

[0021] 1. The downhole equipment anti-collision hydraulic buffer support, with its adjustable length component, can be adjusted to suit the size of the downhole equipment, ensuring excellent buffer protection for any type of downhole equipment to prevent damage. This not only greatly extends the service life of the downhole equipment and reduces the high costs associated with frequent equipment replacements, but also ensures the continuity of downhole operations, avoiding work stoppages due to equipment failure and maintenance, and effectively improving the overall efficiency of downhole production.

[0030] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] Reference Figures 1 to 4 This application provides a hydraulic buffer support for downhole equipment to prevent crushing, including a circular tube 1. A sliding rod 2 is slidably connected to the top of the circular tube 1. A fixing plate 3 is fixedly connected to the outer wall of the circular tube 1. A hydraulic shock absorber 4 is fixedly connected to the top of the fixing plate 3. Length adjustment components 5 are fixedly connected to the tops of both the hydraulic shock absorber 4 and the sliding rod 2. A height adjustment component 8 is threadedly connected to the bottom of the circular tube 1. The length adjustment component 5 includes a hollow plate 51 and a sliding plate 52. The hollow plate 51 is fixedly connected to the tops of the sliding rod 2 and the hydraulic shock absorber 4. The sliding plate 52 is slidably connected to the inner wall of the hollow plate 51. An adjustment groove 53 is provided on the top of the hollow plate 51. A threaded rod 54 is connected to the top of the sliding plate 52 via a bearing. A threaded connection is provided on the side wall of the threaded rod 54. The system includes a lifting plate 55, with connecting plates 56 fixedly installed on both sides of the lifting plate 55. A locking rod 57 is fixedly connected to the bottom of the connecting plate 56, and the locking rod 57 is engaged with the adjusting groove 53. A first stabilizing rod 58 is fixedly connected to the top of the sliding plate 52, and the lifting plate 55 and the first stabilizing rod 58 are slidably connected. The length adjustment assembly 5 also includes a first knob 59, which is fixedly connected to the top of the threaded rod 54. The length adjustment assembly 5 also includes a first limiting block 510, which is fixedly connected to the top of the first stabilizing rod 58. A second stabilizing rod 6 is fixedly connected to the bottom of the hollow plate 51, and the second stabilizing rod 6 is slidably connected to the fixed plate 3. A second limiting block 7 is fixedly connected to the bottom end of the second stabilizing rod 6, and the second limiting block 7 is located below the fixed plate 3.

[0032] In this embodiment, the length adjustment of the support is mainly achieved by the length adjustment component. The decision to adjust the length is made by observing the dimensions of the downhole equipment to be protected. A knob 59 is provided at the top of the length adjustment component 5. When the knob 59 is turned clockwise, the threaded rod 54 is rotated. Since the lifting plate 55 is threadedly connected to the threaded rod 54 and slides up and down along the stabilizing rod 58, the lifting plate 55 will slide upward. At this time, the locking rods 57 on the connecting plates 56 on both sides of the lifting plate 55 will disengage from the adjustment grooves 53 at the top of the hollow plate 51. This releases the restriction on the sliding plate 52, allowing the sliding plate 52 to slide freely within the hollow plate 51. Thus, the length of the entire support can be changed by manually pushing and pulling the sliding plate 52. After adjusting the length, turn knob 59 counterclockwise. The lifting plate 55 descends, and the locking rod 57 re-engages into the adjustment groove 53, thereby fixing the position of the sliding plate 52 and completing the length adjustment operation. This allows it to adapt to downhole equipment of different sizes. After the length and height are adjusted, when the downhole equipment is placed within the protection range of the hydraulic buffer support, in the event of an accidental impact, the hollow plate 51 and the sliding plate 52 will be impacted first. Then, the hollow plate 51 will drive the sliding rod 2 to retract into the interior of the round tube 1, causing the hollow plate 51 to squeeze the hydraulic shock absorber 4. The hydraulic shock absorber 4, utilizing the characteristics of hydraulic buffering, effectively absorbs and disperses the impact force generated by the impact, providing reliable anti-impact buffer protection for the downhole equipment and preventing serious damage to the downhole equipment.

[0033] Reference Figures 1 to 4 In one aspect of this embodiment, the height adjustment assembly 8 includes a threaded rod 81 and a base plate 82. The threaded rod 81 is threadedly connected to the bottom end of the round tube 1, and the base plate 82 is fixedly connected to the bottom end of the threaded rod 81. The height adjustment assembly 8 also includes a knob 83 and an anti-slip pad 84. The knob 83 is fixedly connected to the side wall of the threaded rod 81, and the anti-slip pad 84 is disposed at the bottom of the base plate 82.

[0034] In this embodiment, considering that the ground surface may be uneven when installing underground, it is necessary to adjust the height of the support to ensure its stable placement. The height adjustment component 8 plays a key role. Its side wall is equipped with a knob 83. When the knob 83 is rotated, the threaded rod 81 will rotate. The threaded rod 81 can move up and down relative to the round tube 1, thereby driving the base plate 82 to rise or fall. By performing this operation on the four height adjustment components 8 in sequence, the height of each base plate 82 is adjusted until the entire support is placed stably on the uneven ground, ensuring the overall stability of the support.

[0035] Working principle: The length adjustment of this support is mainly achieved by the length adjustment component. By observing the size of the downhole equipment to be protected, it is determined whether the length adjustment is necessary. A knob 59 is located at the top of the length adjustment component 5. When the knob 59 is turned clockwise, it drives the threaded rod 54 to rotate. Since the lifting plate 55 is threadedly connected to the threaded rod 54 and slides up and down along the stabilizing rod 58, the lifting plate 55 will slide upward. The locking rods 57 on the connecting plates 56 on both sides of the lifting plate 55 will disengage from the adjustment groove 53 at the top of the hollow plate 51. This releases the restriction on the sliding plate 52, allowing the sliding plate 52 to slide freely within the hollow plate 51. The length of the entire support can be changed by manually pushing and pulling the sliding plate 52. After adjusting the length, the knob 59 is turned counterclockwise, the lifting plate 55 descends, and the locking rods 57 re-engage into the adjustment groove 53, thereby fixing the position of the sliding plate 52 and completing the length adjustment operation, making it adaptable to downhole equipment of different sizes.

[0036] Considering the potential unevenness of the underground installation surface, the height of the support needs to be adjusted to ensure stable placement. Height adjustment component 8 plays a crucial role here. Its side wall has a knob 83. Turning the knob 83 in the appropriate position causes the threaded rod 81 to rotate, allowing it to move up and down relative to the circular tube 1, thereby raising or lowering the base plate 82. By sequentially operating the four height adjustment components 8 in this way, the height of each base plate 82 is adjusted until the entire support is stably placed on the uneven ground, ensuring the overall stability of the support.

[0037] After the length and height are adjusted, when the downhole equipment is placed within the protection range of the hydraulic buffer support, in the event of an accidental impact, the hollow plate 51 and the sliding plate 52 will be impacted first. Then, the hollow plate 51 will drive the sliding rod 2 to retract into the interior of the round tube 1, causing the hollow plate 51 to squeeze the hydraulic shock absorber 4. The hydraulic shock absorber 4, utilizing the characteristics of hydraulic buffering, effectively absorbs and disperses the impact force generated by the impact, providing reliable anti-impact buffer protection for the downhole equipment and preventing serious damage to the downhole equipment.
