Technical Field

[0001] This utility model relates to the field of downhole rescue tools, and more specifically, it relates to a downhole rescue tool. Background Technology

[0002] Deep well rescue is one of the more complex and difficult types of rescue work, especially deep wells with small diameters. Rescuers cannot easily go down into them, and the insufficient oxygen supply in the well can also pose a danger to rescuers. In reality, many firefighters have died in deep well rescues. However, the existing underground rescue tools are not stable enough and cannot guarantee a stable descent during the process of going down into the well. Utility Model Content

[0003] (1) Technical problems to be solved

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a downhole rescue tool that is easy to descend stably during the descent process.

[0005] (2) Technical solution

[0006] To achieve the above objectives, this utility model provides an underground rescue tool, comprising a housing, a first bearing at the top of the housing, a first rotating shaft passing through the first bearing, and a first bevel gear fixedly connected to the bottom end of the first rotating shaft, a fixed frame fixedly connected to the top of the housing, and a first motor fixedly connected to the fixed frame, the output shaft of the first motor being fixedly connected to one end of the first rotating shaft, two fixed plates fixedly connected to opposite inner walls of the housing, two second bearings provided on opposite surfaces of the two fixed plates, a second rotating shaft passing through the two second bearings, a second bevel gear fixedly connected to the surface of the second rotating shaft, the first bevel gear meshing with the second bevel gear, a positive threaded column and a negative threaded column fixedly connected to both ends of the second rotating shaft, and two movable plates movably connected inside the housing, two threaded grooves formed on opposite surfaces of the two movable plates, the positive threaded column and the negative threaded column being threadedly connected to the inside of the two threaded grooves respectively;

[0007] The movable plate has a groove on its side, and a buffer assembly is fixedly connected to the inner wall of the groove. A movable block is fixedly connected to one end of the buffer assembly, and a movable rod is fixedly connected to the surface of the movable block. A roller is fixedly connected to one end of the movable rod. A connecting shell is fixedly connected to the bottom of the housing, and a second motor is fixedly connected to the inner wall of the connecting shell. A third bearing is provided at the bottom of the connecting shell, and a third rotating shaft passes through the inside of the third bearing. The output end of the second motor is fixedly connected to the top end of the third rotating shaft, and a second fixed shell is fixedly connected to the bottom end of the third rotating shaft. An electric hydraulic push rod is fixedly connected to each of the opposite inner walls of the second fixed shell. Movable plates are fixedly connected to the opposite ends of the two electric hydraulic push rods, and connecting blocks are fixedly connected to the bottom of the two movable plates. A rectangular through hole is provided at the bottom of the second fixed shell, and clamping plates are fixedly connected to each of the two connecting blocks through the rectangular through hole. A camera is provided at the bottom of the second fixed shell.

[0008] When using the downhole rescue tool of this technical solution, the first motor drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate. The second bevel gear, through the second rotating shaft, drives the positive and negative threaded columns to rotate inside the two threaded grooves. This causes the two movable plates to move on the surfaces of the positive and negative threaded columns, respectively. The two movable plates then drive the two sets of rollers to move, allowing the surfaces of the two sets of rollers to overlap with the inner wall of the well body, thus maintaining stability of the shell during descent. The buffer assembly provides cushioning protection for the device, and the camera allows observation of the situation downhole. As needed, the second motor drives the second fixed shell to rotate, facilitating the rotation and adjustment of the clamping plate. Two electro-hydraulic push rods drive the two movable plates closer together, which, through two connecting blocks, drive the two clamping plates closer together, facilitating the clamping and fixing of objects. The operation is simple and convenient.

[0009] Furthermore, a limiting block is fixedly connected to the top of the movable plate, and a limiting groove is formed on the inner wall of the housing, with the limiting block slidably connected inside the limiting groove.

[0010] Furthermore, the buffer assembly includes a damper, on the surface of which a spring is movably sleeved. One end of the damper and the spring is fixedly connected to the inner wall of the groove, and the other end of the damper and the spring is fixedly connected to the movable block.

[0011] Furthermore, a first fixed shell is fixedly connected to the top of the housing, and a battery pack is disposed inside the first fixed shell. A fixing ring is fixedly connected to the top of the first fixed shell.

[0012] Furthermore, a T-shaped fixing block is fixedly connected to the top of the second fixed shell, and an annular groove is opened at the bottom of the shell, with the T-shaped fixing block movably connected inside the annular groove.

[0013] Furthermore, the surface of the clamping plate is provided with a rubber pad.

[0026] Example:

[0027] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0028] Please see Figure 1-4 This utility model provides a technical solution: a downhole rescue tool, including a housing 1, a first bearing is provided on the top of the housing 1, and a first rotating shaft is passed through the first bearing. A first bevel gear 4 is fixedly connected to the bottom end of the first rotating shaft. A fixed frame is fixedly connected to the top of the housing 1, and a first motor 2 is fixedly connected to the fixed frame. The output shaft of the first motor 2 is fixedly connected to one end of the first rotating shaft. The same fixed plate 5 is fixedly connected to the opposite inner wall of the housing 1. There are two fixed plates 5. A second bearing is provided on the opposite surface of the two fixed plates 5. The same second rotating shaft 6 is passed through the inside of the two second bearings. A second bevel gear is fixedly connected to the surface of the second rotating shaft 6. The first bevel gear 4 meshes with the second bevel gear. A positive threaded column 7 and a negative threaded column 8 are fixedly connected to the two ends of the second rotating shaft 6, respectively. A movable plate 9 is movably connected inside the housing 1. There are two movable plates 9. Threaded grooves 10 are opened on the opposite surface of the two movable plates 9. The positive threaded column 7 and the negative threaded column 8 are respectively threaded into the inside of the two threaded grooves 10.

[0029] A groove 13 is provided on the side of the movable plate 9. A buffer assembly 14 is fixedly connected to the inner wall of the groove 13. A movable block 15 is fixedly connected to one end of the buffer assembly 14. A movable rod 16 is fixedly connected to the surface of the movable block 15. A roller 17 is fixedly connected to one end of the movable rod 16. By setting up a first motor 2, a buffer assembly 14, a positive threaded column 7, and a negative threaded column 8, the first motor 2 drives the first bevel gear 4 to rotate, which in turn drives the second bevel gear to rotate. The second bevel gear then drives the positive threaded column 7 and the negative threaded column 8 through the second rotating shaft 6. The threaded column 8 rotates inside the two threaded grooves 10, causing the two moving plates 9 to move on the surfaces of the positive threaded column 7 and the negative threaded column 8, respectively. This causes the two moving plates 9 to drive the two sets of rollers 17, bringing their surfaces into contact with the inner wall of the well body. This ensures the housing 1 remains stable during descent, and the buffer assembly 14 provides cushioning protection. A connecting shell 18 is fixedly connected to the bottom of the housing 1. A second motor 19 is fixedly connected to the inner wall of the connecting shell 18. A third bearing is located at the bottom of the connecting shell 18, and the interior of the third bearing... A third rotating shaft is provided, and the output end of the second motor 19 is fixedly connected to the top end of the third rotating shaft. A second fixed housing 20 is fixedly connected to the bottom end of the third rotating shaft. Electro-hydraulic push rods 23 are fixedly connected to the inner walls of the two opposing electro-hydraulic push rods 23. Movable plates 24 are fixedly connected to the opposite ends of the two electro-hydraulic push rods 23. Connecting blocks 26 are fixedly connected to the bottom of the two movable plates 24. A rectangular through hole 25 is provided at the bottom of the second fixed housing 20. Clamping plates 27 are fixedly connected to the two connecting blocks 26 through the rectangular through hole 25. The second fixed housing 20... A camera is installed at the bottom. With the camera, second motor 19 and electric hydraulic push rod 23, the situation down in the well can be observed through the camera. As needed, the second motor 19 drives the second fixed shell 20 to rotate, which facilitates the rotation and adjustment of the clamping plate 27. The two electric hydraulic push rods 23 drive the two movable plates 24 to move closer to each other, and the two movable plates 24 drive the two clamping plates 27 to move closer to each other through the two connecting blocks 26, which facilitates the clamping and fixing of items. The operation is simple and convenient.

[0030] Specifically, a limiting block 12 is fixedly connected to the top of the movable plate 9, and a limiting groove 11 is opened on the inner wall of the housing 1, with the limiting block 12 slidably connected inside the limiting groove 11.

[0031] By adopting the above technical solution, the limiting block 12 slides inside the limiting groove 11, which plays a limiting role on the moving plate 9.

[0032] Specifically, the buffer assembly 14 includes a damper 141, with a spring 142 movably sleeved on the surface of the damper 141. One end of the damper 141 and the spring 142 is fixedly connected to the inner wall of the groove 13, and the other end of the damper 141 and the spring 142 is fixedly connected to the movable block 15.

[0033] By adopting the above technical solution, the buffer component 14 plays a role in stretching and elasticity.

[0034] Specifically, a first fixed shell 3 is fixedly connected to the top of the housing 1, a battery pack is installed inside the first fixed shell 3, and a fixed ring 28 is fixedly connected to the top of the first fixed shell 3.

[0035] By adopting the above technical solution, the fixing ring 28 facilitates the fixing of the traction rope.

[0036] Specifically, a T-shaped fixing block 21 is fixedly connected to the top of the second fixed shell 20, and an annular groove 22 is opened at the bottom of the shell 1, with the T-shaped fixing block 21 movably connected inside the annular groove 22.

[0037] By adopting the above technical solution, the second fixed shell 20 is made more stable when it moves by the T-shaped fixing block 21 moving inside the annular groove 22.

[0038] Specifically, the surface of the clamping plate 27 is provided with a rubber pad.

[0039] By adopting the above technical solution, the friction between the clamping plate 27 and the clamped object is increased by the rubber pad, making the clamping plate 27 more stable during clamping.

[0040] The working principle of this utility model is as follows:

[0041] In use, this invention first secures the fixing ring 28 with a cable. Then, the first motor 2 is activated via an external switch, causing it to drive the first bevel gear 4 to rotate. The first bevel gear 4 then drives the second bevel gear to rotate, which in turn drives the positive thread column 7 and the negative thread column 8 to rotate within the two threaded grooves 10 via the second rotating shaft 6. This causes the two moving plates 9 to move on the surfaces of the positive thread column 7 and the negative thread column 8, respectively, and the limiting block 12 to move within the limiting groove 11. The two moving plates 9 then drive the two sets of rollers 17 to move, bringing their surfaces into contact with the inner wall of the well body. Finally, the cable is released, causing the rollers... 17 rolls on the inner wall of the well body, keeping the shell 1 stable during descent, and the buffer assembly 14 provides buffer protection for the device. The camera can observe the situation in the well. As needed, the second motor 19 is started, which drives the second fixed shell 20 to rotate. The rotation of the second fixed shell 20 can adjust the clamping plate 27. Then, the electric hydraulic push rod 23 is started, which drives the two movable plates 24 to move closer to each other. The two movable plates 24, through the two connecting blocks 26, drive the two clamping plates 27 to move closer to each other, thus clamping and fixing the item.

[0042] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
