Description

Technical Field

[0001] This invention belongs to the field of maintenance technology for oil well logging coring equipment, specifically relating to a rubber sealing ring installation tool. Background Technology

[0002] The development of marine oil and gas resources has become a hot topic and focus of the world's marine economy. Marine oil and gas resources are not only abundant, but modern science and technology have also given them a huge capacity for development. The marine oil and gas industry has developed into a new and high-value leading industry in the marine economy.

[0003] Oil well logging and coring are two of the most crucial technologies for obtaining underground geological information in oil and gas exploration and development. Well logging and coring equipment typically utilizes rubber sealing rings to achieve sealing between adjacent components. When workers perform equipment maintenance, they deform the rubber sealing rings using a rope and then place them onto the connecting posts of the well logging and coring equipment.

[0004] Due to the lack of suitable installation tools and differences in personnel operating methods, the following problems occurred during the maintenance process: 1. During installation, the deformation of the sealing ring cannot be accurately controlled due to the different forces used by the personnel, causing inconvenience in installation; 2. Because the stretching process of the cord cannot cause the sealing ring to deform evenly as a whole, the sealing ring is very prone to breakage. 3. The installation process requires axial rotation and stretching of the rope, which may easily damage the sealing surface inside the sealing ring; 4. The rubber seals are highly susceptible to breakage and damage, resulting in a significant waste of resources (approximately 50% damage rate). 5. Due to the difficulty of installation and the large number of units, the workload of maintenance personnel has increased; 6. The inefficient installation method seriously affects the overall maintenance efficiency of the instrument. Summary of the Invention

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be arbitrarily combined with each other.

[0022] like Figure 1 , Figure 2 , Figure 3 The illustration shows an embodiment of the present invention, which discloses a rubber sealing ring installation tool. The tool includes a vertically arranged support rod assembly 1, on which a pusher assembly 2 is vertically slidably mounted. A guide post 3 is coaxially connected to the bottom of the support rod assembly 1. A positioning groove 4 is provided at the bottom of the guide post 3, and the positioning groove 4 can tightly engage with a positioning pin at the top of a connecting post, thereby enabling the guide post 3 and the connecting post to engage coaxially, achieving rapid and accurate positioning of the support rod assembly 1 and the connecting post.

[0023] In one embodiment, such as Figure 1 , Figure 2 As shown, the guide post 3 is provided with a guide surface 5, so that the guide post 3 has a frustum structure with its outer diameter gradually increasing from top to bottom. The diameter of the top of the guide post 3 is the same as the diameter of the bottom of the support rod assembly 1, and the outer diameter of the bottom of the guide post 3 is at least the same as the outer diameter of the connecting post. In this embodiment, it is preferable that the outer diameter of the bottom of the guide post 3 is the same as the outer diameter of the connecting post.

[0024] In one embodiment, such as Figure 1 , Figure 2 As shown, the rubber sealing ring can be fitted onto the support rod assembly 1, and the push assembly 2 is used to push the rubber sealing ring downward so that the rubber sealing ring expands and deforms under the action of the guide surface 5 and fits onto the connecting column, thereby realizing the rapid installation of the rubber sealing ring.

[0025] In this embodiment, the rubber sealing ring installation tool pushes the rubber sealing ring downwards along the guide post 3 via the push assembly 2. Under the action of the guide surface 5, the rubber sealing ring undergoes slow and uniform elastic deformation, reducing the risk of damage or even breakage. Furthermore, this rubber sealing ring installation tool is simple and convenient to operate, reducing the workload of workers and improving work efficiency.

[0026] In one embodiment, such as Figure 1 , Figure 2 As shown, the top of the guide post 3 is threadedly connected to the support rod assembly 1 so that the guide post 3 can be replaced. The operator can replace the guide post 3 with one that matches the size of the connecting post to adapt to different usage needs, thereby improving the adaptability of use.

[0027] In one embodiment, such as Figure 1 , Figure 2 As shown, the support rod assembly 1 includes a central rod 11 and a feeding mechanism 12. The central rod 11 is vertically arranged, and the guide post 3 is coaxially threaded to the bottom of the central rod 11. Multiple rubber sealing rings can be stacked and fitted onto the lower end of the central rod 11. The feeding mechanism 12 is disposed on the central rod 11 and is used to push the multiple rubber sealing rings to move downward synchronously, so that the multiple rubber sealing rings are sequentially located at the connection position between the central rod 11 and the guide post 3.

[0028] In one embodiment, such as Figure 1 , Figure 2 As shown, the feeding mechanism 12 includes a support ring 121, a feeding ring 122, and a feeding spring 123. The support ring 121 is fixed to the middle of the central rod 11, and the feeding ring 122 is slidably sleeved on the lower end of the central rod 11. The feeding spring 123 is sleeved on the central rod 11, with one end of the feeding spring 123 fixedly connected to the support ring 121 and the other end fixedly connected to the feeding ring 122. The feeding spring 123 is used to push the feeding ring 122 downward, so that the feeding ring 122 pushes multiple rubber sealing rings downward synchronously, so that the multiple rubber sealing rings are sequentially located at the connection position between the central rod 11 and the guide post 3.

[0029] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 As shown, the jacking assembly 2 includes a support cap 21, a jacking cylinder 22, and multiple jacking claws 23. The support cap 21 is slidably sleeved on the upper end of the central rod 11, and the jacking cylinder 22 is coaxially and integrally formed and connected to the bottom of the support cap 21. The multiple jacking claws 23 are arranged at equal intervals along the circumference of the jacking cylinder 22, and each jacking claw 23 is fixed to the bottom of the jacking cylinder 22 by a connecting plate 24.

[0030] In this embodiment, the sliding hole on the support cap 21 is tightly fitted with the center rod 11 to play a straightening and guiding role. At the same time, the support ring 121 is tightly fitted with the push sleeve to further improve the straightening and guiding effect, so that the push assembly 2 can slide smoothly.

[0031] In one embodiment, such as Figure 1 , Figure 2 , Figure 3As shown, each pusher claw 23 and the connecting plate 24 are made of elastic material. The bottoms of the multiple pusher claws 23 can deform toward the central rod 11 and are used to jointly push the rubber sealing ring located at the connection position of the central rod 11 and the guide post 3 downward.

[0032] In this embodiment, the support cap 21, the push cylinder 22, the connecting plate 24, and the push claw 23 are made of spring steel or elastic metal material and are integrally formed to improve the structural strength.

[0033] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 As shown, each pusher claw 23 includes an arc-shaped support plate 231, and the support plate 231 is integrally formed and connected to the corresponding connecting plate 24. At least one stress slit 232 is vertically provided at the bottom of the support plate 231, so that at least two pusher plates 233 are formed at the bottom of the support plate 231. In this embodiment, only one stress slit 232 is provided. Meanwhile, each pusher plate 233 has a vertically provided pusher plate 233 at its bottom, and the pusher plate 233 is used to push the rubber sealing ring downwards.

[0034] In one embodiment, such as Figure 1 , Figure 2 As shown, a return spring 6 is fitted on the center rod 11. One end of the return spring 6 abuts against the support cap 21 and the other end abuts against the support ring 121. The return spring 6 is used to push the support cap 21 upward and move the push plate 233 to above the rubber sealing ring located at the connection position between the center rod 11 and the guide post 3.

[0035] When installing rubber sealing rings, stack multiple rubber sealing rings around the bottom of the central rod 11. At this time, under the action of the feeding ring 122, the rubber sealing ring at the bottom position is located at the connection position between the central rod 11 and the guide post 3. Then, insert the guide post 3 into the connecting post, and then grip the multiple push claws 23, so that the multiple push claws 23 move synchronously towards the central rod 11 until the multiple push plates 233 abut against the central rod 11. At this time, the multiple push plates 233 abut against the top of the bottom rubber sealing ring.

[0036] Next, the control support cap 21 drives multiple push claws 23 to move downwards synchronously. Under the combined action of multiple push plates 233, the rubber sealing ring moves downwards along the guide post 3. At this time, the rubber sealing ring gradually expands and deforms until it is fitted onto the connecting post. Then, the feeding ring 122 pushes multiple rubber sealing rings downwards until the lowest rubber sealing ring is located at the connection point between the central rod 11 and the guide post 3.

[0037] Then, the push claw 23 is released, and the support cap 21, under the action of the return spring 6, drives the push claw 23 upward until the push plate 233 moves to above the rubber sealing ring located at the connection position between the center rod 11 and the guide post 3. By repeating this operation, the continuous installation of the rubber sealing ring can be achieved.

[0038] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 As shown, each support plate 231 has elongated stress notches 234 on both sides. The stress notches 234 and stress cuts 232 ensure the effective release of potential energy of the support plate 231 and other components, allowing them to undergo smooth elastic deformation. Furthermore, workers can check the number of rubber sealing rings through the stress notches 234, meaning the stress notches 234 can be used as observation ports.

[0039] In one embodiment, such as Figure 2 As shown, a limiting ring 7 is provided on the central rod 11. The limiting ring 7 is located between the support cap 21 and the support ring 121, and the limiting ring 7 is used to block the support cap 21 from moving downward, so as to limit the maximum vertical downward sliding displacement of the support cap 21 and other components.

[0040] In one embodiment, such as Figure 1 , Figure 2 As shown, the top of the center rod 11 is threaded with an adjusting cap 8, which is used to prevent the support cap 21 from moving upward, thereby limiting the maximum vertical upward sliding displacement of the support cap 21 and other components. In addition, the adjusting cap 8 can also ensure that when the support cap 21 and other components are reset, the push plate 233 moves just above the rubber sealing ring located at the connection position between the center rod 11 and the guide post 3.

[0041] In one embodiment, such as Figure 1 , Figure 2 As shown, the support cap 21 is threadedly connected to the push cylinder 22. The operator can roughly adjust the position of the push plate 233, and at the same time, with the fine adjustment of the adjusting cap 8, the position of the push assembly 2 can be precisely adjusted. This can not only accommodate rubber sealing rings of different widths, but also ensure the accuracy of the push assembly 2's reset.

[0042] As described above, this installation tool enables safe, fast, and reliable installation of rubber seals, making it suitable for maintenance in various environments and reducing the risk of seal damage. Furthermore, the tool is simple and convenient to operate, reducing the workload of workers and improving installation efficiency. Moreover, it is compatible with connection columns of logging and sampling equipment of different sizes and rubber seals of varying widths, effectively enhancing its adaptability.
