Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of petroleum drilling equipment, and particularly relates to a petroleum drilling speed reduction prevention device. BACKGROUND

[0002] When petroleum drilling is carried out, petroleum workers use petroleum drilling equipment to drill through multiple sets of strata along a designed track from the ground to a predetermined target layer (an oil and gas layer or a possible oil and gas layer) to form a stable channel (i.e., an oil and gas well) for oil and gas production or injection of a required fluid (water, gas, steam). In the whole drilling process, a petroleum drilling rig drives a drilling tool to break rocks and drill into the ground to a wellbore of a specified depth. A conventional petroleum drilling rig mainly consists of eight parts, i.e., a power machine, a transmission machine, a working machine and auxiliary equipment. The power equipment of the drilling rig includes an alternating current motor and a direct current motor. The transmission machine of the petroleum drilling rig is responsible for transmitting power generated by the power machine to the working machine. However, the existing petroleum drilling rig equipment still has the following disadvantages in actual use.

[0003] 1. When the existing petroleum drilling rig is used for drilling, the power machine cannot normally provide power when power failure occurs, which immediately causes the whole petroleum drilling rig to be paralyzed. The sudden failure causes personnel to lack reaction time, and the drilling tool equipment in the ground is easily damaged.

[0004] 2. When the alternating current motor or the direct current motor in the power machine of the existing petroleum drilling rig encounters power supply voltage fluctuation, the output power of the motor changes in a short time, the rotating speed of the rotating system in the petroleum drilling rig is reduced in a short time, and the normal use of the petroleum drilling equipment is affected.

[0005] CN108612470A discloses a petroleum drilling equipment, which comprises a base, a support plate, a sliding rail, a sliding block, a horizontal plate, a U-shaped frame, a first bearing seat, a first motor, a spiral conveying shaft and a vertical plate. However, the technical scheme mainly solves the problem that dust appears to affect the surrounding environment by spraying water on the soil through a dust reduction device, and still cannot solve the above technical problems. SUMMARY

[0006] The petroleum drilling speed reduction prevention device provided by the application can solve the problem that the output power of the motor changes in a short time when the power grid power supply fluctuates, the rotating speed of the rotating system in the petroleum drilling rig is reduced in a short time, and the normal use of the petroleum drilling equipment is affected.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0008] A speed reduction prevention device for oil drilling includes a base plate, an energy storage frame fixedly installed on the upper end of the outer wall of the base plate, an output shaft rotatably connected inside the energy storage frame, a flywheel fixedly installed on the side wall of the output shaft and inside the energy storage frame, a support frame fixedly installed on the upper right side of the outer wall of the base plate, an input shaft rotatably connected to the support frame, and the input shaft and the output shaft are poweredly connected through a connecting assembly.

[0009] Furthermore, a bearing sleeve is fixedly installed at the connection between the output shaft and the energy storage frame.

[0010] Furthermore, the connecting assembly includes a connecting frame fixedly connected to the upper end of the outer wall of the base plate, the connecting frame being located between the energy storage frame and the support frame.

[0011] Furthermore, a light rod is fixedly installed on the upper end of the outer wall of the connecting frame, a sliding plate is slidably connected to the outer wall of the light rod, a mounting bracket is fixedly installed on the upper end of the outer wall of the sliding plate, an intermediate shaft is rotatably connected inside the mounting bracket, and a gear is fixedly installed on the side wall of the intermediate shaft and inside the mounting bracket.

[0012] Furthermore, a second gear is fixedly installed on the right side of the outer wall of the output shaft, and the second gear meshes with the first gear.

[0013] Furthermore, a gear three is fixedly installed on the left end of the outer wall of the input shaft, and a gear four is fixedly installed on the right side of the outer wall of the intermediate shaft. The gear four meshes with the gear three.

[0014] Furthermore, an iron core column is fixedly installed on the front end of the inner wall of the connecting frame, and a coil is wound around the side wall of the iron core column.

[0015] Furthermore, an impact block is fixedly installed on the front end of the outer wall of the iron core column.

[0016] Furthermore, an attraction plate is fixedly installed at the lower end of the outer wall of the sliding plate, and a tension spring is fixedly installed between the front end of the outer wall of the attraction plate and the front end of the inner wall of the connecting frame.

[0017] Furthermore, a second support frame is fixedly installed on the upper end of the outer wall of the base plate and on the right side of the energy storage frame, and the output shaft is rotatably connected to the second support frame.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0019] (1) The present invention generates a large moment of rotational inertia by using a high-speed rotating flywheel. When the power supply fluctuates, the flywheel will keep the output shaft at a stable rotational speed for a short time under the action of its rotational inertia, thus avoiding the change in the rotational speed of the rotating system in the oil drilling rig due to fluctuations in the power supply voltage.

[0020] (2) When the present invention is in use, the coil will be de-energized when a power outage occurs, the iron core column will lose its magnetism, and under the action of the tension spring, the sliding plate will be pulled forward to return to its original position, so that gear three and gear four will disengage, and gear two will disengage from gear one. The flywheel in the energy storage box will continue to drive the output shaft to rotate using its huge rotational inertia, so that the drilling equipment can still run for a period of time after the power outage, giving personnel time to react and complete emergency response measures for the drilling equipment after the power outage.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0030] Please seeFigures 1-3 As shown, this invention is a speed reduction prevention device for oil drilling, including a base plate 100. An energy storage frame 200 is fixedly installed on the upper part of the outer wall of the base plate 100. An output shaft 210 is rotatably connected inside the energy storage frame 200. A flywheel 220 is fixedly installed on the side wall of the output shaft 210 and inside the energy storage frame 200. A support frame 300 is fixedly installed on the upper right side of the outer wall of the base plate 100. An input shaft 310 is rotatably connected to the support frame 300. The input shaft 310 and the output shaft 210 are connected by a connecting assembly 400 for power exchange. A bearing sleeve 211 is fixedly installed at the connection between the output shaft 210 and the energy storage frame 200. The bearing sleeve 211 can reduce the friction between the output shaft 210 and the energy storage frame 200. When the output shaft 210 rotates, it can drive the flywheel 220 in the energy storage frame 200 to rotate. The high-speed rotating flywheel 220 generates a large moment of rotational inertia. When the power supply voltage fluctuates, the flywheel 220 will keep the output shaft 210 at a stable rotational speed for a short time under the action of rotational inertia.

[0031] Among them, such as Figures 4-5 As shown, the connecting assembly 400 includes a connecting frame 500 fixedly connected to the upper end of the outer wall of the base plate 100. The connecting frame 500 is located between the energy storage frame 200 and the support frame 300. A light rod 510 is fixedly installed on the upper end of the outer wall of the connecting frame 500. A sliding plate 520 is slidably connected to the outer wall of the light rod 510. A mounting bracket 530 is fixedly installed on the upper end of the outer wall of the sliding plate 520. An intermediate shaft 540 is rotatably connected inside the mounting bracket 530. A gear 550 is fixedly installed on the side wall of the intermediate shaft 540 and inside the mounting bracket 530. When the output shaft 210 slides back and forth on the light rod 510, it can drive the mounting bracket 530 to slide back and forth, thereby causing the gear 550 to move. Gear 550 can move back and forth. Gear 230 is fixedly installed on the right side of the outer wall of the output shaft 210. Gear 230 meshes with gear 550. Gear 320 is fixedly installed on the left end of the outer wall of the input shaft 310. The input shaft 310 is used to connect to the output end of the motor equipment. Gear 460 is fixedly installed on the right side of the outer wall of the intermediate shaft 540. Gear 460 meshes with gear 320. When gear 550 moves backward and meshes with gear 320, gear 320 on the input shaft 310 will mesh with gear 460 at the same time, thereby realizing the transmission of power from the input shaft 310 to the output shaft 210.

[0032] Among them, such as Figures 4-5As shown, a core post 700 is fixedly installed on the front end of the inner wall of the connecting frame 500. A coil 710 is wound around the side wall of the core post 700. An attraction plate 740 is fixedly installed on the lower end of the outer wall of the sliding plate 520. A tension spring 760 is fixedly installed between the front end of the outer wall of the attraction plate 740 and the front end of the inner wall of the connecting frame 500. An impact block 600 is fixedly installed on the front end of the outer wall of the core post 700. The impact block 600 is used to buffer the impact force during impact. When the coil 710 is energized, it will cause the core post 700 to generate magnetism. The front end of the coil 710 attracts the front attraction plate 740, causing the sliding plate 520 to slide backward on the light rod 510. When the power is off, the coil 710 will be de-energized, the iron core column 700 will lose its magnetism, and under the action of the tension spring 760, the sliding plate 520 will be pulled forward to return to its original position, causing the gear 320 and gear 4 560 to disengage, and the gear 230 and gear 1 550 to disengage. At the same time, the flywheel 220 in the energy storage frame 200 will continue to rotate due to its huge rotational inertia, allowing the drilling equipment to continue to operate for a period of time after the power is off.

[0033] Among them, such as Figure 1 As shown, a support frame 210 is fixedly installed on the upper part of the outer wall of the base plate 100 and on the right side of the energy storage frame 200. The output shaft 210 is rotatably connected to the support frame 210, and the support frame 210 is used to further support the output shaft 210.

[0034] A specific application of this embodiment is as follows: During use, the input shaft 310 is connected to the output end of the motor device. When the coil 710 is energized, the iron core column 700 will generate magnetism, attracting the front attraction plate 740 through the front end of the iron core column 700. This causes the sliding plate 520 to slide backward on the guide rod 510, thereby driving the mounting bracket 530 to slide backward. This allows gear one 550 to move backward, enabling gear one 550 to mesh with gear three 320 and gear three 320 to mesh with gear four 560. This transmits the power from the input shaft 310 to the output shaft 210. When the output shaft 210 rotates, it can drive the flywheel in the energy storage frame 200. The flywheel 220 rotates, generating a large moment of inertia. When the power supply voltage fluctuates, the flywheel 220, under the action of rotational inertia, keeps the output shaft 210 at a stable rotational speed for a short period of time. When a power outage occurs, the coil 710 is de-energized, the iron core column 700 loses its magnetism, and under the action of the tension spring 760, the sliding plate 520 is pulled forward to return to its original position, causing gears 320 and 4560 to disengage, and gears 230 and 1550 to disengage. At the same time, the flywheel 220 in the energy storage frame 200 continues to rotate due to its huge moment of inertia, allowing the drilling equipment to continue to operate for a period of time after a power outage.
