Description

Technical Field

[0001] This invention relates to the field of downhole instrument storage and loading / unloading equipment, and specifically to an automatic loading / unloading instrument rack for downhole operations. Background Technology

[0002] Downhole instruments are indispensable detection and monitoring equipment in underground engineering operations such as mining, tunneling, and oil and gas wells. They are mainly used for core operations such as detecting downhole environmental parameters, monitoring equipment operating status, and collecting geological data. Downhole instruments require storage, transportation, and loading / unloading operations before and after use. However, traditional instrument racks have limited functions and mostly only provide simple placement and storage.

[0003] Existing downhole instrument racks have several shortcomings in practical use: First, instrument loading and unloading largely rely on manual handling and alignment. Downhole operations are often confined and complex, making manual loading and unloading not only labor-intensive and inefficient, but also prone to damage due to operational errors, posing significant safety hazards. Second, traditional instrument racks cannot achieve self-adaptive clamping and fixing of instruments. After placement, instruments are prone to displacement and shifting during transport and downhole operations, resulting in poor stability, which can easily affect instrument accuracy and even cause them to fall off and be damaged. Third, the existing instrument racks have an unreasonable support structure layout, failing to provide stable support for various downhole instruments. Furthermore, they lack loading and unloading guidance and power assistance structures, resulting in extremely low automation and failing to meet the operational requirements of efficient and safe loading, unloading, and storage of modern downhole instruments. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an automated loading and unloading instrument rack, resolving the issues of low efficiency, poor safety, and insufficient instrument stability associated with manual loading and unloading of downhole instruments as described in the background art. This rack enables batch storage of downhole instruments and automated loading and unloading, replacing extensive manual labor and improving both operational efficiency and safety.

[0005] To achieve the above objectives, the present invention employs the following technical solution: an automatic loading and unloading instrument rack, comprising a storage module for placing downhole instruments, a hoisting module for moving downhole instruments in and out of the storage module above the storage module, the storage module comprising a support frame, a support component, a clamping component, and a power component at the lower part of the support frame; the hoisting module comprising a movable frame located above the support frame, one end of the movable frame being provided with an adapter for connecting downhole instruments, and the other end being provided with a drive source.

[0006] As a further improvement to the above technical solution: The power component is located at the front end of the support frame. There are multiple support components and clamping components, which are staggered along the length of the support frame.

[0007] The support assembly includes a mounting frame, which has a storage compartment. A support roller is located at the bottom of the storage compartment, and a support plate is located on one side of the support roller.

[0008] The number of rollers is multiple, and they are evenly distributed along the width of the storage compartment.

[0009] The number of storage compartments is multiple, and they are evenly distributed along the height direction of the mounting frame.

[0010] The clamping assembly includes a second mounting frame, with a clamping airbag on the upper part of the second mounting frame and a roller group below the clamping airbag. A placement gap for placing downhole instruments is formed between the clamping airbag and the roller group. The height of the placement gap is adjusted by changing the thickness of the clamping airbag, thereby clamping or releasing the downhole instruments.

[0011] The number of roller groups is two and they are symmetrically distributed about the center line of the compression airbag. Each roller group includes a crossbar, on which multiple rollers are evenly distributed along the axial direction of the crossbar. These rollers cooperate with multiple rollers to support different positions of the downhole instrument.

[0012] The power assembly includes a mounting frame three, which has a channel for downhole instruments to pass through. A rotating shaft is provided at the lower part of the channel, and a supporting roller is provided on the rotating shaft. A roller three located in front of the rotating shaft in the direction of travel is provided in the mounting frame three.

[0013] The number of the three idlers is multiple and they are evenly distributed along the length of the mounting frame. The number of the rotating shafts corresponds to the number of the three idlers. Each rotating shaft is provided with a support roller, and the position of the support roller on each rotating shaft corresponds to that of one of the three idlers.

[0014] Multiple rotating shafts form a power unit, and at least two sets of power units are arranged in the channel along the length direction of the mounting frame three.

[0015] The beneficial effects of this invention are as follows: The automatic loading and unloading instrument rack includes a storage module for placing downhole instruments. Above the storage module is a hoisting module for moving downhole instruments in and out of the storage module. The storage module includes a support frame. The lower part of the support frame is provided with a support component, a clamping component, and a power component. By using the hoisting module and the power component in cooperation, the loading and unloading of downhole instruments (especially long cylindrical downhole instruments) can be realized. Compared with the existing methods that require a large number of manual loading and unloading, this method can greatly reduce the number of operators, adapt to the narrow space downhole, reduce the labor intensity of operators, and improve the efficiency of loading and unloading downhole instruments. The structure adopts a staggered layout of multiple sets of support components and clamping components. The support components are equipped with multi-layer storage compartments, which can realize the layered storage of multiple downhole instruments, with large storage capacity and high space utilization. The idler rollers work together with the support plate to provide all-round stable support for the bottom of the instrument, ensuring the stability of the instrument placement. By using the clamping airbag and the roller assembly to form a placement gap, and by adjusting the gap height by adaptively changing the thickness of the clamping airbag, it can accommodate downhole instruments of different sizes. At the same time, the flexible clamping fixation avoids damage to the instrument shell caused by rigid clamping, and can also effectively prevent downhole instruments from rotating or sliding. Through the cooperation of multiple power units, support rollers and idler rollers, auxiliary power can be provided for the loading and unloading of downhole instruments. Together with the hoisting module, the instruments can be loaded and unloaded smoothly and stably, avoiding jamming and displacement, and further improving the stability and smoothness of automated loading and unloading.

[0018] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0019] like Figure 1-8 As shown, this embodiment provides an automatic loading and unloading instrument rack, including a storage module for placing downhole instruments, and a hoisting module above the storage module for moving the downhole instruments in and out of the storage module.

[0020] The storage module includes a support frame 1 that serves as the overall load-bearing base. The lower part of the support frame 1 is equipped with a support component, a clamping component, and a power component. The hoisting module includes a movable frame 2 located above the support frame 1. The movable frame 2 can reciprocate along the length of the support frame 1. One end of the movable frame 2 is fixedly installed with an adapter 3 for quick docking and connecting downhole instruments. The adapter 3 uses an electric hoist and can be adapted and disassembled according to the specifications of the downhole instruments to ensure connection stability. The other end of the movable frame 2 is equipped with a drive source 4. The drive source 4 can use a servo motor, electric push rod, or other drive structure to provide power support for the movement of the movable frame 2 and the hoisting and moving of the instruments.

[0021] The power unit, serving as the power input for instrument loading and unloading, is located at the front end of the support frame 1. Multiple support and clamping components are provided and evenly distributed along the length of the support frame 1, ensuring that each downhole instrument can be matched with an independent support, guaranteeing the support and fixation effect of each instrument, and avoiding interference between multiple instruments.

[0022] The support assembly includes a mounting frame 5, which is fixedly mounted below the support frame 1. Multiple storage compartments 6 are evenly arranged within the mounting frame 5. In this embodiment, there are two storage compartments 6, equidistantly arranged along the height of the mounting frame 5 to increase storage capacity. Each storage compartment 6 is equipped with a roller 7 at its bottom. Multiple rollers 7 are evenly distributed along the width of the storage compartment 6. In this embodiment, each layer has three rollers 7, capable of storing three downhole instruments. A support plate 8 is fixedly mounted on one side of each roller 7. The roller 7 reduces friction during instrument pushing, pulling, loading, and unloading, providing sliding guidance. The support plate 8, together with the rollers 7, forms a composite support structure to support the bottom of the instrument, preventing partial suspension and ensuring stable placement.

[0023] The clamping assembly includes a second mounting frame 9, which is fixed below the support frame 1 and is staggered with the support assembly. A clamping airbag 10 is fixedly installed on the upper part of the inner side of the second mounting frame 9. The clamping airbag 10 can achieve adaptive thickness adjustment by inflating and deflating. A roller group 11 is symmetrically arranged below the clamping airbag 10. The clamping airbag 10 and the roller group 11 below form a placement gap 14, which is the placement position for downhole instruments. During operation, the height of the placement gap 14 can be flexibly adjusted by controlling the inflation volume of the compression airbag 10 to change its thickness. When the airbag inflates, the gap height decreases, achieving flexible compression and fixation of the downhole instrument; when the airbag deflates and contracts, the gap height increases, releasing the compression limit on the instrument and completing the instrument release. The operation is convenient, and the flexible compression method will not damage the instrument shell. While compressing, it protects the surface of the downhole instrument. The number of compression airbags 10 corresponds to the number of idler rollers 13, realizing the compression and release of a single downhole instrument. When storing multiple downhole instruments at the same time, individual loading and unloading operations can be performed on a single downhole instrument.

[0024] Two roller sets 11 are provided, symmetrically distributed about the vertical centerline of the compression airbag 10 to ensure uniform force on the instrument and provide support during compression. Each roller set 11 includes a horizontally arranged crossbar 12, which is fixed to the mounting frame 9. Multiple rollers 13 are mounted on the crossbar 12, and the rollers 13 are evenly distributed along the axial direction of the crossbar 12. The rollers 13 of the two roller sets 11 cooperate with each other and are coaxially distributed with the rollers 7 of the support assembly to support different positions of the downhole instrument, further improving the stability of the instrument placement.

[0025] The power assembly includes a mounting frame 3 15 fixed to the front end of the support frame 1. The mounting frame 3 15 has a through-channel 16 for the entry and exit of downhole instruments. Channel 16 is the necessary passage for instrument loading and unloading. A rotating shaft 17 is rotatably mounted at the lower part of channel 16, and support rollers 18 are fixedly mounted on the rotating shaft 17 to support the instruments and provide rolling power. Inside the mounting frame 3 15, in front of the rotating shaft 17 in the direction of travel, is a support roller 3 19. The support roller 3 19 cooperates with the support rollers 18 to provide bidirectional support and guidance for the instruments.

[0026] The system comprises multiple idler rollers 19 evenly arranged along the length of the mounting frame 15. The number of rotating shafts 17 corresponds to the number of idler rollers 19. In this embodiment, three idler rollers 19 are selected, and three rotating shafts 17 are also selected, distributed sequentially along the length of the support frame 1. Each rotating shaft 17 is independently equipped with a support roller 18, and each support roller 18 is directly opposite the corresponding idler roller 19. The support roller 18 rotates with the rotating shaft 17, driving one of the downhole instruments to move. The corresponding idler roller 19 supports and guides the corresponding downhole instrument, enabling individual transport of three downhole instruments placed side-by-side in the same layer, avoiding mutual interference. Multiple rotating shafts 17 rotate synchronously to form a power unit. At least two power units are arranged along the length of the channel 16. The coordinated operation of multiple power units provides continuous and stable transport power for downhole instruments of different lengths and weights, assisting the hoisting module in completing automated instrument loading and unloading operations, effectively improving the stability of the transport operation.

[0027] The working process is as follows: When storing the instrument, the drive source 4 drives the moving frame 2 to move. It is connected to the end hook of the downhole instrument through the adapter 3, and the instrument is transported to the corresponding placement gap 14 inside the support frame 1. The bottom of the instrument is supported by roller 1 7, roller 2 13, support roller 18 and roller 3 19. Then, the pressure airbag 10 is controlled to inflate and expand, reducing the height of the placement gap 14, and flexibly pressing and fixing the downhole instrument to complete the automated storage. When the instrument is taken out, the pressure airbag 10 is first controlled to deflate and contract to release the instrument. Then, the power unit of the power component drives the instrument forward. At the same time, the moving frame 2 of the hoisting module pulls the instrument to automatically move it out of the storage module, completing the automated loading and unloading operation. The whole process does not require manual handling, and the operation is efficient, safe and stable.
