Description

Technical Field

[0001] This utility model relates to the field of oil extraction technology, and more specifically, to an oil extraction fracturing unit. Background Technology

[0002] In the oil extraction industry, fracturing is a key process for increasing oil well production. Currently, with the increasing demand for extraction in deep and complex geological conditions, the stability of fracturing equipment is becoming increasingly prominent. During operation, traditional fracturing trucks often experience equipment displacement or tilting due to uneven ground and severe vibrations caused by high-pressure operation, which seriously affects operational efficiency and safety. The simple support structures used in existing technologies usually only employ fixed-height support legs or hydraulic support systems. These systems not only have limited adjustment ranges but are also prone to loosening or deformation during long-term operation, making them unable to adapt to complex and changing terrain environments. The problem of unstable support is even more prominent in soft soil areas or on sloping ground.

[0003] In high-pressure operating environments, every component of the equipment must remain stable to ensure the safe operation of the entire system. Most of the connecting components of existing fracturing equipment use simple bolt fixing or pin locking methods. These connection methods are prone to loosening under continuous vibration, and the adjustment process is cumbersome, requiring frequent manual inspection and adjustment by staff.

[0008] The present invention is further configured such that a knob is fixedly provided at the top of each of the multiple sets of screws, and an anti-slip strip is fixedly provided on the outer wall of each of the multiple sets of knobs. The height can be adjusted by manually rotating the screws through the knobs, and the anti-slip strips enhance the grip stability, improve the adjustment accuracy and operating comfort.

[0009] The present invention is further configured such that multiple sets of base plates are fixedly provided with support blocks on their outer walls. The support blocks are provided in multiple sets, which increases the contact area with the ground, improves the support stability, reduces the support instability caused by uneven ground, and ensures that the fracturing truck can remain stable under various terrain conditions.

[0010] The present invention is further configured such that the outer sides of the multiple sets of locking blocks and the inner sides of the locking rings are all set as inclined surfaces. The inclined surface design enables the locking blocks and locking rings to automatically tighten when subjected to force, forming a more secure locking effect, effectively preventing loosening or falling off under long-term vibration environment, and improving the reliability and safety of the entire locking mechanism.

[0011] The present invention is further configured such that the outer wall of the fixed sleeve is provided with a sliding groove, and multiple sets of sliding grooves are provided. The unlocking sleeve is slidably provided inside the fixed sleeve. The multiple sets of sliding grooves guide the movement direction of the unlocking sleeve, ensuring that the unlocking sleeve can slide smoothly without deviation, thereby improving the accuracy and reliability of the unlocking operation.

[0012] The present invention is further configured such that a slider is fixedly provided on the outer wall of the unlocking sleeve, and the slider is provided with multiple sets that slide in multiple sets of sliding grooves respectively. A sliding sleeve is fixedly provided on the outer wall of the slider. The sliding of multiple sets of sliders in multiple sets of sliding grooves can ensure that the unlocking sleeve moves more stably along the inner wall of the fixed sleeve.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an oil fracturing unit with the following advantages:

[0017] 1. The oil fracturing unit provided by this utility model solves the problem of insufficient stability of traditional fracturing equipment in uneven ground and high-pressure operating environments. By setting an adjustable support mechanism on the outside of the fracturing truck, the support mechanism adopts a design that combines a fixed cylinder and a sliding support plate, so that the support plate can slide freely in the fixed cylinder to adjust its height according to the terrain conditions. The precise height adjustment is achieved through the cooperation of the screw and the base plate. The outer wall of the base plate is also equipped with multiple sets of support blocks to increase the contact area with the ground, which greatly improves the adaptability and stability of the entire fracturing unit in various complex terrains and ensures that the equipment will not shift or tilt during high-pressure operation.

[0018] 2. The snap-fit ​​mechanism of this utility model innovatively solves the problem of traditional connecting parts being prone to loosening under vibration. The mechanism uses the clever cooperation between the fixed sleeve and the plug rod to drive the snap-fit ​​block and the snap-fit ​​ring to be tightly snapped together by the compression spring in the movable groove, forming a reliable locking state. In particular, the outer side of the snap-fit ​​block and the inner side of the snap-fit ​​ring are designed with a beveled structure, which can automatically tighten when subjected to force, effectively preventing loosening or falling off under long-term vibration. Moreover, the entire locking process can be completed without tools, which greatly simplifies the operation process and improves work efficiency.

[0019] 3. This utility model also features a convenient unlocking mechanism. The sliding sleeve moves the unlocking sleeve to compress the locking block, thus quickly releasing the locked state. The push spring on the sliding rod ensures that the unlocking sleeve automatically resets after release. The entire unlocking process is simple and intuitive to operate, and can be easily completed even in harsh environments. At the same time, the anti-slip strip design on the outer wall of the knob enhances the operating feel and improves the adjustment accuracy. These design details together constitute a safe, reliable, and easy-to-operate support system, which greatly improves the safety and efficiency of oil fracturing operations, reduces the risk of equipment failure and operation interruption, and creates significant economic benefits for oil companies.

[0029] Please see Figures 1-5 An oil fracturing unit includes a fracturing truck 1. A support mechanism is provided on the outside of the fracturing truck 1. The support mechanism includes a fixed cylinder 2 and a support plate 3. The fixed cylinder 2 is fixed to the bottom surface of the fracturing truck 1. The support plate 3 slides inside the fixed cylinder 2. A fixing hole 4 is provided on the support plate 3. A screw 5 is threadedly connected to the top of the support plate 3. A base plate 6 is fixed to the bottom of the screw 5. An insert rod 7 is inserted into the fixing hole 4. A locking mechanism is provided at the top of the insert rod 7. The locking mechanism includes a fixed sleeve 8 and a locking block 9. The fixed sleeve 8 is fixed to the top surface of the fixed cylinder 2. The insert rod 7 is inserted into the fixed sleeve 8 and has a movable groove 10 on its outer wall. Multiple sets of movable grooves 10 are provided, and each set of grooves 10 has a compression spring 11 connected to its inner wall. The multiple sets of compression springs 11 are respectively fixedly connected to the inner side of multiple sets of locking blocks 9. A retaining ring 12 is fixedly provided on the inner wall of the fixed sleeve 8.

[0030] Each of the multiple sets of screws 5 has a knob 13 fixedly installed at its top. Each of the multiple sets of knobs 13 has an anti-slip strip 14 fixedly installed on its outer wall. The knob 13 serves as the operating end of the screw 5. By manually rotating the knob 13, the screw 5 can be driven to make a spiral motion within the support plate 3, thereby achieving precise height adjustment. The anti-slip strip 14 increases the surface friction, prevents hand slippage, and ensures the stability and accuracy of the adjustment process.

[0031] Multiple sets of base plates 6 are fixed with support blocks 15 on their outer walls. The support blocks 15 are arranged in multiple sets. The multiple sets of support blocks 15 increase the contact area between the base plate 6 and the ground, disperse the pressure distribution, and avoid the ground sinking or damage to the base plate 6 caused by excessive force on a single point. At the same time, the multi-point support improves the overall stability, so that the fracturing truck 1 can maintain a stable state on uneven ground.

[0032] The outer sides of multiple sets of locking blocks 9 and the inner sides of locking rings 12 are all set as inclined surfaces. The inclined surface design forms a wedge-shaped locking structure. When the locking block 9 contacts the locking ring 12, it will generate a radial component force under the action of axial force, so that the locking block 9 is more tightly locked into the locking ring 12, forming a self-locking effect. The greater the force, the more secure the locking, effectively preventing loosening and falling off in a vibration environment.

[0033] The outer wall of the fixed sleeve 8 is provided with a sliding groove 16, and multiple sets of sliding grooves 16 are provided. The unlocking sleeve 17 is slidably provided inside the fixed sleeve 8. The sliding groove 16 provides a motion guide for the unlocking sleeve 17, ensuring that the unlocking sleeve 17 can only move up and down along the preset track without deflection, thus improving the accuracy of the unlocking operation. At the same time, multiple sets of sliding grooves 16 are distributed around the fixed sleeve 8, ensuring the smoothness of the movement of the unlocking sleeve 17.

[0034] The outer wall of the unlocking sleeve 17 is fixedly provided with a slider 18. The slider 18 is provided with multiple sets that slide in multiple sets of slide grooves 16 respectively. The outer wall of the slider 18 is fixedly provided with a sliding sleeve 19. The slider 18 serves as a connecting part between the unlocking sleeve 17 and the slide grooves 16, ensuring that the movement of the unlocking sleeve 17 is accurately controlled. The sliding sleeve 19 serves as an operating handle, allowing the operator to hold and push the slider 18. The slider 18 drives the unlocking sleeve 17 to move, forming a mechanical transmission chain from external operation to internal unlocking.

[0035] The outer wall of the fixed sleeve 8 is fixedly provided with a slide rod 20. There are multiple sets of slide rods 20, all of which are slidably connected to the slide sleeve 19. Each set of slide rods 20 has a push spring 21 on its outer wall. The two ends of the push spring 21 are respectively connected to the slide sleeve 19 and the fixed sleeve 8. The slide rods 20 provide track support for the movement of the slide sleeve 19. The even distribution of multiple sets of slide rods 20 ensures stable movement. The push spring 21 is in a compressed state and stores elastic potential energy. When the operating force is released, the push spring 21 releases energy and automatically pushes the slide sleeve 19 and the unlocking sleeve 17 back to their original positions, realizing the automatic reset function.

[0036] The fracturing vehicle 1 is equipped with an engine unit 22. A heat dissipation box 23 is provided on one side of the engine unit 22. The engine unit 22 provides power to the fracturing unit and generates a lot of heat during operation. The heat dissipation box 23 accelerates heat dissipation by increasing the heat dissipation area and air circulation, preventing the engine unit 22 from overheating and causing performance degradation or damage, and ensuring the continuous and stable operation of the fracturing equipment.

[0037] In this embodiment, during use, the support plate 3 is slid out of the fixed cylinder 2 to a suitable length, and then the insert rod 7 is inserted into the fixed sleeve 8 and the fixed hole 4. The retaining ring 12 abuts against the outer wall of the multiple sets of retaining blocks 9, so that the multiple sets of retaining blocks 9 slide into the movable groove 10 and squeeze the multiple sets of compression springs 11. When the multiple sets of retaining blocks 9 are fully inserted into the fixed sleeve 8, the multiple sets of compression springs 11 reset and push the retaining blocks 9 out of the movable groove 10. The bottom surface of the multiple sets of retaining blocks 9 abuts against the outer wall of the retaining ring 12 to fix the insert rod 7. The support plate 3 is fixed by the insert rod 7. Then, the knob 13 is turned to drive the screw 5 to rotate and engage with the support plate 3 by thread, so that the screw 5 pushes the bottom plate 6 to abut against the bottom surface. The multiple sets of support mechanisms and retaining mechanisms are operated in sequence to support the fracturing truck 1.

[0038] More specifically, when it is necessary to unlock the support plate 3, push the sliding sleeve 19 to make multiple sets of sliders 18 slide along the sliding groove 16, and drive the unlocking sleeve 17 to slide along the inner wall of the fixed sleeve 8. The unlocking sleeve 17 abuts against the outer wall of multiple sets of locking blocks 9, so that multiple sets of locking blocks 9 slide into the movable groove 10 and squeeze multiple sets of compression springs 11, so that multiple sets of locking blocks 9 release the contact with the retaining ring 12. Then the insertion rod 7 can be pulled out of the fixed sleeve 8 and the fixed sleeve 8 to release the fixation of the support plate 3.

[0039] In summary, during the use or operation of the overall equipment: When in use, slide the support plate 3 out of the fixed cylinder 2 to a suitable length, then insert the rod 7 into the fixed sleeve 8 and the fixed hole 4, and abut against the outer wall of the multiple sets of locking blocks 9 through the retaining ring 12, so that the multiple sets of locking blocks 9 slide into the movable groove 10 and squeeze the multiple sets of compression springs 11. When the multiple sets of locking blocks 9 are fully inserted into the fixed sleeve 8, the multiple sets of compression springs 11 reset and push the locking blocks 9 out of the movable groove 10. The bottom surface of the multiple sets of locking blocks 9 abuts against the outer wall of the retaining ring 12 to fix the rod 7. The support plate 3 is fixed through the rod 7. Then, turn the knob 13 to drive the screw 5 to rotate and engage with the support plate 3 through the thread, so that the screw 5 pushes the bottom plate 6 to abut against the bottom surface. The multiple sets of support mechanisms and locking mechanisms are operated in sequence to support the fracturing truck 1.

[0040] When it is necessary to unlock the support plate 3, push the sliding sleeve 19 to make multiple sets of sliders 18 slide along the sliding groove 16, and drive the unlocking sleeve 17 to slide along the inner wall of the fixed sleeve 8. The unlocking sleeve 17 abuts against the outer wall of multiple sets of locking blocks 9, so that multiple sets of locking blocks 9 slide into the movable groove 10 and squeeze multiple sets of compression springs 11, so that multiple sets of locking blocks 9 release the contact with the locking ring 12. Then the insertion rod 7 can be pulled out of the fixed sleeve 8 and the fixed sleeve 8 to release the fixation of the support plate 3.
