Description

Technical Field

[0001] The invention relates to the technical field of drilling derricks, in particular to an anti-falling column split type oil drilling support frame. Background Art

[0002] The oil drilling support frame is an indispensable supporting device in the oil drilling process and is the foundation for oil drilling operations.

[0003] In the field of oil drilling, workers need to use auxiliary steel cables to ensure safety when climbing the working platform of the drilling derrick, but the existing technology has many problems: on the one hand, the inspection of the tension of the steel cables is not strict, and there is a lack of perfect standards and procedures, so it is impossible to accurately judge whether it meets the safety requirements; when the steel cables are loose, they cannot provide effective support when the workers fall accidentally, causing injuries or even life-threatening situations; when the steel cables are too tight, the risk of them breaking will increase. Once they break, the workers will lose protection, which will also cause serious casualties.

[0004] On the other hand, the frequency of inspection is insufficient. Due to the tediousness and consideration of time and efficiency, inspection is not carried out before each climb, and potential problems are difficult to detect in time. In addition, professional testing tools are inconvenient to use, complicated and require professional personnel to operate and interpret the results. Non-professional workers find it difficult to understand and master them, and the safety of the wire rope cannot be fully guaranteed.

[0005] In addition, although auxiliary steel cables and electrical sensing devices are provided in the prior art, the prior art still has deficiencies in the safety protection against falling of workers when climbing drilling rigs. The overall protection system is not perfect enough to fully guarantee the safety of workers under various complex working conditions. The electrical sensing method relies on electronic equipment and sensors to detect the fall of workers. However, electronic equipment is susceptible to interference in complex industrial environments such as drilling rigs. For example, there are a large number of electromagnetic interference sources at the drilling site, such as electromagnetic fields generated by motors, electric welders and other equipment, which will affect the normal operation of the electrical sensing device, resulting in misjudgment or omission of the worker's fall. Moreover, the sensor of the electrical sensing device will fail due to long-term exposure to harsh environments (such as moisture, dust, high temperature, etc.). Once the sensor fails, the entire fall detection system will not be able to work normally and will not be able to detect the worker's fall in time, thereby endangering the worker's life safety.

[0006] Therefore, the present invention proposes a split-type oil drilling support frame with an anti-falling column to solve the above problems. Summary of the invention

[0007] In view of this, the technical problem to be solved by the present invention is to propose a split-type oil drilling support frame with anti-falling columns to solve the problems existing in the prior art.

[0012] Preferably, a first magnet block is fixedly connected to the outer end surface of the right-angle piece, and a second magnet block is fixedly connected to the drilling derrick at an equidistant distance.

[0013] Preferably, the safety processing component includes a second cavity opened on the safety buckle, in which the electric drive wheel A and the electric drive wheel B are rotatably connected, and the electric drive wheel A and the electric drive wheel B are laterally distributed in the second cavity.

[0014] Preferably, vertical grooves are equidistantly fixedly connected in the electrically driven wheel A, an auxiliary spring D is fixedly connected in the vertical groove, a counterweight block is fixedly connected at one end of the auxiliary spring D away from the fixed end, the counterweight block is slidably connected in the vertical groove, an electric contact A is fixedly connected to the counterweight block, and an electric contact B is fixedly connected on the inner cavity wall of the electrically driven wheel A and located in the vertical groove.

[0015] Preferably, the outer circumference of the circular ring of the electric drive wheel A is equidistantly fixed with plug-in columns, the electric drive wheel B is equidistantly provided with plug-in interfaces, the plug-in columns are provided with limiting holes, and the inner cavity of the electric drive wheel B is equidistantly fixed with electric telescopic rods.

[0016] Preferably, the magnetic poles of the opposite surfaces of the first magnet block and the second magnet block are the same; a pair of first magnet blocks is provided, and a plurality of second magnet blocks are provided, and are distributed at different heights of the climbing ladder.

[0017] Preferably, the inner surfaces of the electrically driven wheels A and B are both provided with high-friction spherical protrusions made of rubber material.

[0018] Compared with the prior art, the present invention provides a split-type oil drilling support frame with an anti-fall column, which has the following beneficial effects: 1. The present invention, through the design of the anti-fall safety detection component, allows workers to check the steel cable before climbing the ladder each time, and can directly observe the liquid level height in the liquid level indicator cavity to judge whether the tension of the steel cable meets the use standard. This intuitive visual feedback mechanism can effectively avoid the situation where the protection ability of the workers is reduced due to the steel cable being too loose or too tight; specifically, the second magnetic block adopts an equidistant multi-point design, which can effectively By utilizing the mobility of the safety buckle on the steel cable and the cooperation between the multi-point first and second magnet blocks, the tension at different positions of the steel cable, i.e. at different heights, can be accurately detected, thereby ensuring whether the tension at each point affects the overall tension of the steel cable. This effectively avoids the situation that is difficult to understand and grasp due to insufficient inspection frequency, insufficient operation and interpretation ability of non-professional workers, and eliminates the situation where the steel cable is loose and cannot provide effective support when the worker falls accidentally, and the steel cable is too tight and increases the risk of breakage, thereby avoiding the situation where the worker loses protection after breakage and causes serious casualties.

[0019] 2. The present invention has the following advantages through the design of the first magnet block and the second magnet block: First, under the action of the repulsive force between magnets, it has the advantage of no wear compared to mechanical contact sensors. Mechanical contact sensors are prone to wear during long-term use due to direct contact with the object being measured; for example, when using a mechanical contact to detect changes in the tension of a steel cable, the contact will continue to rub with the vibration and movement of the steel cable, causing contact wear, affecting the measurement accuracy and the service life of the sensor; while the magnet detects through the action of magnetic force, there is no mechanical contact, no wear problem, and can maintain stable detection performance for a long time; at the same time, the magnet feeds back information through direct magnetic attraction, the magnetic action is clear and direct, and is relatively less affected by external interference, and can more accurately reflect the changes in the tension of the steel cable.

[0020] Second, compared with optical detection methods, it is not affected by ambient light. For example, when using laser ranging to detect parameters related to cable tension, the measurement results are easily disturbed by ambient light. At the drilling site, there are strong light exposure and light reflection, which will greatly reduce the measurement accuracy of optical sensors. The detection principle of magnets is based on magnetic force and has nothing to do with ambient light. Whether in strong light during the day or in the dark at night, it can stably detect and ensure the reliability of the detection results.

[0021] The present invention indirectly feeds back the tension of the steel cable into the solution in the liquid level indicating cavity. This feedback using the solution has the following advantages: First, visual and intuitive feedback. This design provides a very intuitive visual feedback mechanism. When the push plate pushes the solution and transfers it to the liquid level indicating cavity of the indicating container, the operator can directly judge the tension of the steel cable by observing the amount of solution in the indicating container. The transfer amount of the solution is more intuitive, and even non-professionals can easily understand and judge the state of the steel cable.

[0022] Second: quantitative evaluation basis. The amount of solution transferred can be used as a basis for quantitative evaluation of the cable tension. By calibrating the amount of solution transferred under different tensions in advance, for example, when the cable is at normal tension, the amount of solution transferred is a certain value. When the tension deviates from the normal range, the amount of solution transferred will increase or decrease accordingly. In this way, the operator can compare the actual amount of solution in the indicator container with the calibrated value, so as to more accurately evaluate whether the cable tension is within a reasonable range.

[0023] Third: Advantages of historical data recording and analysis; the data of solution transfer volume can be easily recorded; the amount of solution transferred each time and the corresponding time and other information can be recorded. These historical data are very helpful for analyzing the tension change trend of the steel cable in different time periods and working conditions. By analyzing these data, the law of cable tension change can be discovered, and problems that will arise can be predicted in advance, providing a scientific basis for the maintenance and replacement of the steel cable.

[0024] 4. The present invention promotes the improvement of the overall protection system through the provision of safety processing components, which can effectively ensure the safety of workers under various complex working conditions; and this method of stopping the falling of the safety buckle on the steel cable through the cooperation between machines is different from the prior art that relies on electronic equipment and sensors to detect the fall of workers. Instead, it is triggered by the influence of centrifugal force on the counterweight block, avoiding the problem that electronic equipment is easily interfered with in complex industrial environments such as drilling derricks; for example, there are a large number of electromagnetic interference sources at the drilling site, such as electromagnetic fields generated by motors, electric welders and other equipment, which will affect the normal operation of the electrical sensing device, resulting in misjudgment or omission of the worker's fall.

[0025] 5. The present invention adopts the design of spherical protrusions with high friction coefficients on the electric-driven wheels A and B. This braking method does not rely on complex electronic equipment or control systems, and can provide a relatively stable braking effect under various working conditions; and the risk of failure is low. Compared with some complex braking systems, such as electromagnetic braking systems that may fail due to power failure, or hydraulic braking systems that may lose braking ability due to hydraulic oil leakage, the structure of friction braking is relatively simple, which can effectively reduce the risk of failure of the braking system and improve the safety of the safety buckle operation; at the same time, friction braking can be adjusted according to the different loads carried by the safety buckle; when the safety buckle carries a heavier load, the pressure can be increased to increase the friction, thereby ensuring that the movement of the safety buckle can be effectively prevented; when carrying a lighter load, the pressure can be appropriately reduced to avoid excessive braking affecting the normal operation of the safety buckle.

[0055] For further examples, please refer to Figure 2 , Figures 7 to 10 As shown: the safety processing component 6 is used to physically lock the safety buckle 402 that is sliding down. The safety processing component 6 includes a second cavity 601 opened on the safety buckle 402. The second cavity 601 is rotatably connected with an electric drive wheel A602 and an electric drive wheel B603. The electric drive wheel A602 and the electric drive wheel B603 are horizontally distributed in the second cavity 601. The electric drive wheel A602 is equidistantly fixedly connected with a vertical groove 604. The vertical groove 604 is fixedly connected with an auxiliary spring D605.

Electric telescopic rods 611 are fixedly connected to the inner cavity of the electric drive wheel B603 at equidistant intervals.

[0056] Among them: the electric drive wheel A602 and the electric drive wheel B603 are both driven by motors. When the anti-fall safety detection component 5 is working, the components in the component can be moved on the steel cable 401, and the inner surfaces of the electric drive wheel A602 and the electric drive wheel B603 are provided with high-friction spherical protrusions made of rubber material.

[0057] The vertical channel 604 is mainly used to provide movement guidance for the counterweight 606 .

[0058] The auxiliary spring D605 is mainly used for resetting the counterweight 606 .

[0059] When the electric drive wheel A602 rotates rapidly, the counterweight block 606 is acted upon by the centrifugal force and moves away from the center of the electric drive wheel A602.

[0060] There is an electrical connection between the electrical contact A607 and the electrical contact B608 and the master control of the device. When the electrical contact A607 and the electrical contact B608 are in contact, the master control will control the electric telescopic rod 611 to extend so as to be inserted into the limiting hole 610 opened on the plug-in column 609.

[0061] The electric telescopic rod 611 is electrically connected to the electric contact A 607 and the electric contact B 608 through the master control in the device.

[0062] The working principles of all the contents in the above embodiments are as follows: in the initial state: the auxiliary spring A503, the auxiliary spring B509, and the auxiliary spring C512 are in a normal relaxed state and are not compressed; the first magnet block 514 and the second magnet block 515 are not adsorbed to each other; there is no solution in the liquid level indicating cavity 513; the electrical contact A607 and the electrical contact B608 are not in contact; the plug-in column 609 is not plugged into the plug port 6091, and the electric telescopic rod 611 is not plugged into the limiting hole 610.

[0063] The following is the working process of the anti-fall safety detection component 5: when a worker climbs the climbing ladder 3, he first needs to control the safety buckle 402 to move back and forth from the steel cable 401 to detect the tension of the steel cable 401. Specifically, when the safety buckle 402 moves on the steel cable 401, the first magnet block 514 in the anti-fall safety detection component 5 will gradually approach and eventually be on the same horizontal plane as the second magnet block 515 on the climbing ladder 3. Please refer to the attached Figure 5 And attached Figure 6 When the first magnet block 514 and the second magnet block 515 are on the same horizontal plane, under the effect of magnetism, the first magnet block 514 will move away from the second magnet block 515 through the right-angle piece 504 with the triangular block 505. At this time, the auxiliary spring A503 is compressed. Further, at this time, the triangular block 505 will gradually approach and push the vertical bar 506 on the T-shaped support member 502 to move downward. As the vertical bar 506 moves downward, please refer to the attached Figure 4In the process of the vertical bar 506 moving downward, the gas entering the inner cavity of the square cavity 507 through the air inlet hole 508 will be pushed by the vertical bar 506, and enter the lower part of the inner cavity of the square cavity 507 through the one-way air valve plate 510. At this time, the auxiliary spring B509 is in a compressed state. With the transfer of the gas, the push plate 511 will be forced to move downward under the action of the gas and squeeze the solution set at the bottom of the inner cavity of the square cavity 507. At this time, the pushed solution will enter the liquid level indicating cavity 513 connected to the square cavity 507; at this time, the solution transfer is completed once, and when the first magnet block 514 is no longer on the same horizontal plane with the second magnet block 515, all components return to their original positions.

[0064] It should be noted that, as is known, there are multiple second magnet blocks 515, and they are distributed at different heights of the climbing ladder 3. Therefore, after the safety buckle 402 carries the anti-fall safety detection component 5 to move back and forth on the steel cable 401 once, the above-mentioned solution transfer action will occur multiple times. If the tension of the steel cable 401 is just right, the distance between the steel cable 401 and the climbing ladder 3 should remain unchanged, that is, the amount of solution transfer indirectly caused by the magnetic repulsion between the first magnet block 514 and the second magnet block 515 should be consistent.

[0065] Furthermore, by indirectly feeding back the tension of the steel cable 401 into the solution in the liquid level indication cavity 513, this design provides a very intuitive visual feedback mechanism. When the push plate 511 pushes the solution and transfers it to the liquid level indication cavity 513 of the indicating container, the operator can directly judge the tension of the steel cable 401 by observing the amount of solution in the indicating container. The amount of solution transferred is more intuitive, and even non-professionals can easily understand and judge the state of the steel cable 401. In addition, it has a quantitative evaluation basis, and the amount of solution transferred can be used as a measure of the tension of the steel cable 401. A basis for quantitative evaluation of tension; by calibrating the solution transfer amount under different tension conditions in advance; in addition, it has the advantage of historical data recording and analysis; the data of solution transfer amount can be easily recorded; the amount of solution transferred each time and the corresponding time and other information can be recorded. These historical data are very helpful for analyzing the tension change trend of steel cable 401 in different time periods and working conditions. By analyzing these data, the law of tension change of steel cable 401 can be discovered, and problems that may occur can be predicted in advance, providing a scientific basis for the maintenance and replacement of steel cable 401.

[0066] Furthermore, the present invention has the advantage of being wear-free compared to mechanical contact sensors through the design of the first magnet block 514 and the second magnet block 515 under the action of the repulsive force between the magnets, and can effectively avoid the wear of the mechanical contact sensor due to direct contact with the object to be measured during long-term use; at the same time, compared with the optical detection method, it is not affected by ambient light, thereby ensuring the reliability of the detection result.

[0067] Furthermore, the present invention, through the design of the anti-fall safety detection component 5, allows the worker to check the steel cable 401 before climbing the climbing ladder 3 each time, and can directly observe the liquid level height in the liquid level indication cavity 513 to judge whether the tension of the steel cable 401 meets the use standard. This intuitive visual feedback mechanism can effectively avoid reducing the protection ability of the workers due to the steel cable 401 being too loose or too tight. Specifically, the second magnetic block 515 adopts an equidistant multi-point design, which can effectively utilize the moving characteristics of the safety buckle 402 on the steel cable 401. The point-type first magnet block 514 and the second magnet block 515 cooperate with each other to accurately detect the tension at different positions of the steel cable 401, that is, at different heights, and thus ensure whether the tension at each point affects the overall tension of the steel cable 401; effectively avoid the situation that is difficult to understand and grasp due to insufficient inspection frequency, insufficient operation and interpretation ability of non-professional workers; prevent the steel cable 401 from being loose and unable to provide effective support when the worker falls accidentally, and the steel cable 401 is too tight to increase the risk of breakage, thereby avoiding the situation where the worker loses protection after breakage and causes serious casualties.

[0068] Please refer to the above working process Figures 1 to 6 .

[0069] The following is the working process of the safety processing component 6: Furthermore, if a worker falls while climbing the climbing ladder 3, the electric drive wheels A602 and B603 on both sides of the steel cable 401 will rotate rapidly. Figure 8 And attached Fig. 9As the electric drive wheel A602 rotates rapidly, the counterweight block 606 will move to a position close to the electric contact B608 under the action of centrifugal force, and finally contact the electric contact B608. In this process, the auxiliary spring D605 is stretched. Furthermore, since it is known that the electric contacts A607, the electric contacts B608 and the master control of the device are electrically connected, when the electric contacts A607 and the electric contacts B608 are in contact, the master control will control the electric telescopic rod 611 to extend, so as to be plugged into the limiting hole 610 opened on the plug-in column 609. 602 and the electric drive wheel B603 rotate rapidly. That is, when a worker falls, when the plug-in column 609 on the electric drive wheel A602 is plugged into the plug-in interface 6091 provided on the electric drive wheel B603, the electric telescopic rod 611 in the electric drive wheel B603 will extend and insert into the limiting hole 610 on the plug-in column 609, and the rubber ball protrusions with high friction provided on the inner surfaces of the electric drive wheels A602 and B603 will come into contact with the steel cable 401, thereby limiting the continued rotation of the electric drive wheels A602 and B603.

[0070] Furthermore, the present invention adopts the design of spherical protrusions with high friction coefficients on the electric-driven rotating wheel A602 and the electric-driven rotating wheel B603. This braking method does not rely on complex electronic equipment or control systems, and can provide a relatively stable braking effect under various working conditions; and the risk of failure is low. Compared with some complex braking systems, such as electromagnetic braking systems that may fail due to power failure, or hydraulic braking systems that may lose braking ability due to hydraulic oil leakage, the structure of friction braking is relatively simple, which can effectively reduce the risk of failure of the braking system and improve the safety of the operation of the safety buckle 402; at the same time, friction braking can be adjusted according to the different loads carried by the safety buckle 402; when the safety buckle 402 carries a heavier load, the pressure can be increased to increase the friction, thereby ensuring that the movement of the safety buckle 402 can be effectively prevented; when carrying a lighter load, the pressure can be appropriately reduced to avoid excessive braking affecting the normal operation of the safety buckle 402.

[0071] Furthermore, the present invention promotes the improvement of the overall protection system through the provision of the safety processing component 6, which can effectively ensure the safety of workers under various complex working conditions; and this method of stopping the falling of the safety buckle 402 on the steel cable 401 through the cooperation between machines is different from the prior art that relies on electronic equipment and sensors to detect the fall of workers. Instead, it is triggered by the influence of centrifugal force on the counterweight block 606, avoiding the problem that electronic equipment is easily interfered in a complex industrial environment such as the drilling derrick 1; for example, there are a large number of electromagnetic interference sources at the drilling site, such as the electromagnetic field generated by motors, electric welders and other equipment, which will affect the normal operation of the electrical sensing device, resulting in misjudgment or omission of the worker's fall.
