Description

Technical Field

[0001] The utility model belongs to the technical field of petroleum drilling auxiliary equipment, in particular to a drilling ball throwing device. Background Art

[0002] In the process of oil and gas exploration and development, it is necessary to carry out drilling work according to the geological design of the stratigraphic layer and depth, insert the coring tool into the well, and drill out the rock samples. The core is a valuable basic data for the oil field. At present, there are two main coring processes for formation coring, hydraulic pressure coring and ball-dropping pressure coring. The latter requires a special drilling ball-dropping device to achieve it.

[0003] A Chinese patent discloses a safe ball-dropping device for oil drilling (Announcement No. CN211819328U). This patented technology is easy to operate and facilitates dropping steel balls into the drill tool one by one to complete multiple ball-dropping operations. By pre-placing the steel balls in the ball storage tube, the drill tool does not need to be disassembled during the ball-dropping operation, reducing the risk during the disassembly process, improving safety, and facilitating use. However, during the ball-dropping process, manual operation is required by the staff. On the one hand, manual operation greatly increases the workload of the staff. On the other hand, it is difficult for the staff to control the thrust, and it is easy for the staff to use too much force in the process of pushing the second movable rod, pushing two steel balls at the same time, affecting the normal ball-dropping operation. Utility Model Content

[0004] In view of the shortcomings of the existing technology, such as the need for manual operation by workers during the drilling ball throwing process, on the one hand, manual operation greatly increases the workload of workers, and on the other hand, it is difficult for workers to control the thrust, and it is easy for workers to use excessive force when pushing the second moving rod and push two steel balls at the same time, thereby affecting the normal ball throwing operation. Therefore, the utility model provides a new drilling ball throwing device to solve the above problems.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A drilling ball throwing device, comprising:

[0007] A connecting tube, wherein a first through hole is formed in the middle of the top surface of the connecting tube, a ball storage tube is connected to the upper portion of the connecting tube near the first through hole, a fixed disc is connected to the inner wall of the connecting tube, a second through hole is formed inside the fixed disc, a material guide tube is connected to the upper portion of the fixed disc, the top end of the material guide tube is connected to the top surface of the inner wall of the connecting tube, and a plurality of steel balls are connected to the inner portion of the material guide tube;

[0008] A support frame is connected to the inner wall of the connecting pipe near the bottom of the fixed disc, one end of the support frame is connected to a servo motor, one end of the servo motor output shaft is connected to a movable disc, and a third through hole is opened inside the movable disc.

[0009] In a possible implementation, a diameter of the first through hole is consistent with a diameter of the second through hole.

[0010] In a possible implementation, the position of the top feed port of the material guiding tube corresponds to the position of the first through hole, and the position of the discharge port of the material guiding tube corresponds to the position of the second through hole.

[0011] In a possible implementation, a group of sliders are connected to the left and right sides of the movable disc respectively, and the outer sides of the sliders are connected to sliding seats, and the sliding seats are fixedly connected to the connecting pipe.

[0012] In a possible implementation, a power line is connected through the right side of the connecting tube, and one end of the power line is electrically connected to the servo motor.

[0013] In one possible implementation, a single-chip microcomputer and a signal receiver are connected to the left side wall of the connecting tube near the top of the fixed disc, and the single-chip microcomputer is located above the signal receiver. An infrared reflective sensor is connected to the left side wall of the connecting tube near the bottom of the fixed disc and above the slide, and a refraction plate is connected to the right side wall of the connecting tube near the bottom of the fixed disc and above the slide.

[0014] In a possible implementation, an early warning device is connected above the connecting tube and close to the right side of the ball storage tube.

[0015] The beneficial effects of the utility model are as follows:

[0016] 1. The device is provided with a servo motor, a fixed disc, a movable disc and a guide tube. A plurality of steel balls are placed in the ball storage tube, and the steel balls enter the guide tube. Then the servo motor is turned on to drive the movable disc to rotate. When the third through hole in the movable disc moves to just below the second through hole in the fixed disc, it is convenient to drop the steel balls into the drilling tool through the second through hole and the third through hole. Then the movable disc continues to rotate. When the third through hole in the movable disc is staggered with the second through hole in the fixed disc, the steel balls are prevented from falling, so that only one steel ball can be dropped after one rotation of the movable disc. The operation steps are simple, which reduces the manual operation steps of the staff, solving the problem of increasing the workload of the staff on the one hand and easily pushing in two steel balls on the other hand, affecting the normal ball throwing operation.

[0017] 2. This device is equipped with an infrared reflective sensor, an early warning device and a refraction plate. When the infrared reflective sensor is turned on, the projected infrared ray is irradiated on the outside of the steel ball, and the landing point is not on the refraction plate, so that the infrared reflective sensor cannot receive the reflected infrared ray. When the steel ball is released, the projected infrared ray is irradiated on the refraction plate, so that the reflected infrared ray is received by the infrared reflective sensor. The data is uploaded to the microcontroller through the signal receiver, and then the microcontroller controls the early warning device to alarm, which is used to remind the staff that the steel ball release is completed and more steel balls need to be added.

[0027] A drilling ball throwing device, comprising:

[0028] A connecting tube 3 is provided with a first through hole 6 in the middle of the top surface of the connecting tube 3. A ball storage tube 1 is connected to the upper portion of the connecting tube 3 near the first through hole 6. A fixed disc 14 is connected to the inner wall of the connecting tube 3. A second through hole 8 is provided inside the fixed disc 14. A material guide tube 7 is connected to the upper portion of the fixed disc 14. The top end of the material guide tube 7 is connected to the top surface of the inner wall of the connecting tube 3. A plurality of steel balls 5 are connected to the inner portion of the material guide tube 7.

[0029] A support frame 9 is connected to the inner wall of the connecting pipe 3 near the bottom of the fixed disc 14. One end of the support frame 9 is connected to a servo motor 10. One end of the output shaft of the servo motor 10 is connected to a movable disc 16. A third through hole 11 is opened inside the movable disc 16.

[0030] In some examples, the diameter of the third through hole 11 is consistent with the diameter of the second through hole 8 , so that the steel ball 5 can be dropped into the drilling tool through the second through hole 8 and the third through hole 11 .

[0031] In some examples, the top feed port position of the guide tube 7 corresponds to the position of the first through hole 6, and the discharge port position of the guide tube 7 corresponds to the position of the second through hole 8, so that the steel ball 5 can pass smoothly through the interior of the guide tube 7 and enter the drilling tool.

[0032] In some examples, a group of sliders 17 are connected to the left and right sides of the movable disc 16, and a slide seat 18 is connected to the outer side of the slider 17. The slide seat 18 is fixedly connected to the connecting tube 3. The connection between the slider 17 and the slide seat 18 is beneficial to improve the stability of the movable disc 16 during the rotation process.

[0033] In some examples, a power cord 4 is connected through the right side of the connecting tube 3 , one end of the power cord 4 is electrically connected to the servo motor 10 , and the other end of the power cord 4 is connected to a power socket, which is beneficial for providing power support to the servo motor 10 .

[0034] By adopting the above technical solutions:

[0035] A servo motor 10, a fixed disc 14, a movable disc 16 and a guide tube 7 are provided. A plurality of steel balls 5 are placed in the ball storage tube 1, and the steel balls 5 enter the inside of the guide tube 7. Then the servo motor 10 is turned on to drive the movable disc 16 to rotate. When the third through hole 11 in the movable disc 16 moves to just below the second through hole 8 in the fixed disc 14, it is convenient to drop the steel balls 5 into the drilling tool through the second through hole 8 and the third through hole 11. Then the movable disc 16 continues to rotate. When the third through hole 11 in the movable disc 16 is staggered with the second through hole 8 in the fixed disc 14, the steel balls 5 are prevented from falling, so that the movable disc 16 can only drop one steel ball 5 after one rotation. The operation steps are simple, which reduces the steps of manual operation of the staff, solving the problem of increasing the workload of the staff on the one hand and easily pushing in two steel balls 5 on the other hand, affecting the normal throwing operation.

When the infrared reflection sensor 15 is turned on, the projected infrared ray is irradiated on the outside of the steel ball 5, and the landing point is not on the refraction plate 19, so that the infrared reflection sensor 15 cannot receive the reflected infrared ray. When the steel ball 5 is finally delivered, the projected infrared ray is irradiated on the refraction plate 19, so that the reflected infrared ray is received by the infrared reflection sensor 15, and the data is uploaded to the inside of the single-chip microcomputer 12 through the signal receiver 13, and then the single-chip microcomputer 12 controls the early warning device 2 to alarm, which is used to remind the staff that the delivery of the steel ball 5 is completed and the steel ball 5 needs to be added.
