Description

Technical Field

[0001] The invention relates to the technical field of auxiliary equipment for oil production, and in particular to a rotational force torque increasing driving device for oil production. Background Art

[0002] In the process of oil extraction, drill pipes are usually used for extraction. In order to increase the torque of the drill pipe, a common method is to manually operate during the rotation of the drill pipe, usually by quickly winding a chain around the drill pipe to slow down the rotation speed of the drill pipe and instantly increase the torque of the drill pipe. In this way, workers are first required to quickly wind the chain around the drill pipe, which requires certain work experience of the workers. On the other hand, since the chain is wrapped around the drill pipe, whether it is taken out or kept wrapped, the drill pipe always keeps rotating during this process, which makes it easy for the chain to be thrown out of control and cause an accident.

[0003] In order to solve this problem, we propose a rotational torque increasing device for the drill rod, which can effectively increase the torque of the drill rod without human operation. Summary of the invention

[0004] In view of the defects in the prior art, the present invention provides a rotational force torque increasing driving device for oil production, so as to increase the torque of the drill pipe without human operation.

[0005] The present invention provides a rotational torque-increasing driving device for oil extraction, comprising: a mounting bottom, the mounting bottom comprising a mounting main sleeve and a rotating disk; one end of the mounting main sleeve is mounted on a drill pipe and passes through the drill pipe; the rotating disk is mounted on the other end of the mounting main sleeve and is rotatably arranged on the mounting main sleeve; a torque-increasing portion, the torque-increasing portion is arranged on the mounting bottom; the torque-increasing portion comprises a sliding sleeve, an abutting main slider, a torque-increasing weight, an abutting cone head and an abutting cylinder; one end of the sliding sleeve is fixedly mounted on the mounting main sleeve; the sliding sleeve is provided with at least one slideway, the abutting main slider is slidably mounted on the slideway; one end of the abutting cone head abuts against the abutting main slider; the other end of the abutting cone head is fixedly mounted on the output shaft of the abutting cylinder; the abutting main slider is provided with an abutting cone surface segment, and the abutment cone segment abuts the abutment cone head; the abutment cylinder is installed on the mounting main sleeve and is close to the sliding sleeve direction; the torque-increasing weight is installed on the abutment main sliding block; the torque-increasing weight abuts the outer wall of the drill pipe; and a friction part, the friction part is arranged on the torque-increasing part; the friction part includes a sandblasting assembly, which is installed at the abutment main sliding block; the sandblasting assembly includes a sandblasting tube, a sand box and a pushing member; the sandblasting tube is communicated with the sand box and is located in the slideway; and the pipe mouth of one end of the sandblasting tube faces the outer surface of the drill pipe; one end of the pushing member is installed in the sandblasting tube; the other end of the pushing member is transmission-connected with the abutment main sliding block; wherein the sand box is filled with sand and gravel, and under the push of the pushing member, the sandblasting tube sprays the sand to the outer wall of the drill pipe.

[0006] Furthermore, the rotating disk is rotatably mounted on the mounting main sleeve via a bearing. In actual use, the purpose of this design is to ensure effective support for the torque increasing part and the friction part, so that the device can rotate together with the drill rod, thereby achieving the technical requirement of increasing the torque of the drill rod, and thus effectively ensuring the increase of the torque.

[0007] Furthermore, the sliding sleeve is provided with four slideways, and the abutting main sliders are provided with four slideways, wherein the abutting main sliders are respectively slidably mounted on the slideways. In actual use, the slideways in this design are evenly arranged, so that evenly distributed twisting of the drill rod is achieved, so that the force on the drill rod is uniform, and deformation of the drill rod caused by unidirectional force is avoided. In addition, under the condition of multi-directional offset force, the deflection of the drill rod is effectively solved, and the rotation of the drill rod is more stable; the problem of eccentric rotation is effectively solved.

[0008] Furthermore, the pusher includes a push rod, a spring and a piston head, wherein the piston head is installed at one end of the push rod and is located in the sandblasting tube; the other end of the push rod is connected to the abutting main slider; the spring is installed outside the push rod, and one end of the spring is connected to the abutting main slider; the other end of the spring abuts against the mouth of the sandblasting tube. In actual use, the purpose of this design is to achieve the sandblasting effect, thereby increasing the friction resistance on the surface of the drill rod, so that in the process of increasing torque, the abutment of the torque-increasing weight and the surface of the drill rod will not be separated due to the slipping of the drill rod, and then the torque increase will fail; because in actual work, oily liquid often adheres to the surface of the drill rod, so that in the traditional chain torque increase process, the flying parts will not hurt people due to slipping. In this device, on the one hand, because the device is unmanned, on the other hand, because the device adopts the technology of sandblasting resistance increase, the friction slip phenomenon is eliminated; in this way, the stability of rotation can be better guaranteed. In actual work, after the push rod is pushed against the main slider, it pushes the piston head to move, so that the sand and gravel in the sandblasting tube are ejected outward under the push of the piston head. The spring plays a role of limiting protection to avoid collision.

[0009] Furthermore, the friction part also includes at least one electric heating tube, which is arranged outside the sandblasting tube and passes through the sandblasting tube, and the electric heating tube is electrically connected to an external power supply and is used to heat the sandblasting tube. In actual use, the purpose of this design is to heat the sandblasting tube, and then heat the sand and gravel. In this way, the hot sand can impact the surface of the drill pipe, thereby forming a surface heat source, accelerating the change of oil on the surface of the drill pipe, and making the friction effect of the torsion weight better after abutment. Since the heat is distributed and scattered on the surface, similar to the distribution of a shotgun on the surface, this design enables the torsion weight above the sandblasting tube to effectively contact the sand and gravel ejected from the sandblasting tube below.

[0010] Furthermore, the electric heating tube is provided at two locations, which are installed one by one on the sandblasting tube. In actual use, the purpose of this design is to adopt the interval installation so that the hot sand and the unheated cold sand are evenly arranged alternately, so that the alternation of hot and cold is realized, so that the friction resistance of the torsion weight is further increased; and the above-mentioned drill rod and torsion weight are further prevented from slipping.

[0011] Furthermore, the friction part also includes a rotary spraying assembly, which includes a rotary spraying head, a motor and a fixed gear; one end of the rotary spraying head is rotatably mounted at the nozzle of the sandblasting tube, and the fixed gear is fixedly mounted on the outer wall of the rotary spraying head; the motor is transmission-connected to the fixed gear and drives the rotary spraying head to rotate. In actual use, the purpose of this design is to sandblast a larger range, so that more resistance can be added during the contact between the torsion-increasing weight and the surface of the drill rod; in actual work, when the sand and gravel on the surface of the drill rod first contact the torsion-increasing weight, the sand and gravel will slide during the force and rotation of the drill rod, and then scratch the surface of the drill rod. In this way, when the torsion-increasing weight approaches the surface of the drill rod again, the friction resistance will increase, and the tightening effect of the torsion-increasing weight will be more stable.

[0012] Furthermore, liquid is injected into the sand box. In actual use, the liquid can be water; the purpose of this design is to achieve cooling and prevent the heat caused by the equipment from being transferred to the sand in the sand box.

[0013] It can be seen from the above technical solution that the beneficial effects of the torque-increasing driving device for oil production provided by the present invention are: (1) In actual use, the device is installed as a whole on a rotatable drill rod through the installation bottom, thereby achieving effective support for the entire device. In actual use, the main installation sleeve used can be effectively sleeved on the drill rod; and the rotating disk is rotatably installed on the main installation sleeve; in this way, the torque increasing part can rotate with the drill rod; (2) At the same time, the sliding sleeve on the torque increasing part is fixedly connected with the rotating disk, thereby realizing effective synchronous transmission, so that the abutment cylinder and other accessories in the torque increasing part can rotate together; in this way, the torque of the rotating drill rod can be increased, so that the drill rod can increase and reduce torque during its rotation, effectively ensuring different effects during the working process of the drill rod; and the torque increasing weight block used moves together with the drill rod, and the torque is increased by the weight of the torque increasing weight block itself; and through the above-mentioned abutment cylinder, that is, the electric cylinder, through the effective abutment between its abutment cone head and the abutment main slider, the abutment main slider is pushed to slide, so that the torque increasing weight block installed on the abutment main slider approaches the surface of the drill rod until it is abutted and fixed; (3) A friction part is also provided in the machine, and its main function is to increase the friction effect. The sand and gravel are ordinary fine sand and gravel. BRIEF DESCRIPTION OF THE DRAWINGS

In actual use, the main installation sleeve 11 used can be effectively installed on the drill rod 400; and the rotating disk 12 is rotatably installed on the main installation sleeve 11; in this way, the torque increasing part 2 can be rotated together with the drill rod 400; at the same time, the sliding sleeve 21 on the torque increasing part 2 is fixedly connected with the rotating disk 12, thereby realizing effective synchronous transmission, so that the abutting cylinder 25 and other accessories in the torque increasing part 2 can be rotated together; in this way, the rotating drill rod 400 can be increased. Torque, in this way, the drill rod 400 can increase and reduce torque during rotation, effectively ensuring different effects during the working process of the drill rod 400; and the torque-increasing weight 23 used moves with the drill rod 400, and the torque is increased through the gravity of the torque-increasing weight 23 itself; and through the above-mentioned abutment cylinder 25, that is, the electric cylinder, through its abutment cone head 24 and the abutment main slider 22, the abutment main slider 22 is pushed to slide, and then the torque-increasing weight 23 installed on the abutment main slider 22 is close to the surface of the drill rod 400 until it is abutted and fixed; and in it, a friction part 3 is also provided, and its main function is to increase the friction effect. The sand and gravel are ordinary fine sand and gravel.

[0019] In this embodiment, for the convenience of installation, the rotating disk 12 is rotatably mounted on the mounting main sleeve 11 through a bearing. In actual use, the purpose of this design is to ensure effective support for the torque increasing part 2 and the friction part 3, so that the device and the drill rod 400 can rotate together, thereby achieving the technical requirement of increasing the torque of the drill rod 400, and thus effectively ensuring the increase of torque.

[0020] At the same time, in order to achieve effective and uniform application of torque, in this embodiment, the sliding sleeve 21 is provided with four slideways 211, and the abutting main sliders 22 are provided with four, wherein the abutting main sliders 22 are respectively slidably mounted on the slideways 211. In actual use, the slideways 211 in this design are evenly arranged, so that the uniform torque increase of the drill rod 400 is achieved, so that the force of the drill rod 400 is even, and the deformation of the drill rod 400 caused by unidirectional force is avoided. In addition, under the condition of multi-directional offset force, the deflection of the drill rod 400 and other problems are effectively solved, so that the rotation of the drill rod 400 is more stable; the problem of eccentric rotation is effectively solved.

[0021] In this embodiment, the pushing member 313 includes a push rod 3131, a spring 3132 and a piston head 3133, wherein the piston head 3133 is installed at one end of the push rod 3131 and is located in the sandblasting tube 311; the other end of the push rod 3131 is connected to the abutting main slider 22; the spring 3132 is installed outside the push rod 3131, and one end of the spring 3132 is connected to the abutting main slider 22; the other end of the spring 3132 abuts against the pipe mouth of the sandblasting tube 311. In actual use, the purpose of this design is to achieve the sandblasting effect, thereby increasing the friction resistance on the surface of the drill rod 400, so that in the process of increasing the torque, the torque increasing weight 23 will not be separated from the surface of the drill rod 400 due to the slipping of the drill rod 400, and then the torque increasing will fail; because in actual work, there is often oily liquid attached to the surface of the drill rod 400, so that in the traditional chain torque increasing process, the situation of flying parts injuring people due to slipping will not happen again in this device. On the one hand, because the device adopts unmanned operation, on the other hand, because the device adopts the technology of sandblasting resistance increase, the friction slip phenomenon is eliminated; in this way, the stability of rotation can be better guaranteed. In actual work, after the push rod 3131 is pushed by the main slider 22, it pushes the piston head 3133 to move, so that the sand and gravel in the sandblasting tube 311 are ejected outward under the push of the piston head 3133, wherein the spring 3132 plays the role of limit protection to avoid collision.

[0022] At the same time, in order to increase resistance and avoid slipping, in this embodiment, the friction part 3 also includes at least one electric heating tube 32, which is arranged outside the sandblasting tube 311 and penetrates the sandblasting tube 311, and the electric heating tube 32 is electrically connected to an external power supply and used to heat the sandblasting tube 311. In actual use, the purpose of this design is to heat the sandblasting tube 311, and then heat the sand and gravel. In this way, hot sand can impact the surface of the drill rod 400, thereby forming a surface heat source, accelerating the change of oil on the surface of the drill rod 400, and making the friction effect of the torsion weight 23 better after abutment. Since the heat is distributed and scattered on the surface, similar to the distribution of a shotgun hitting the surface, this design enables the torsion weight 23 above the sandblasting tube 311 to effectively contact the sand and gravel ejected from the sandblasting tube 311 below. In order to further avoid the occurrence of slippage, in this embodiment, the electric heating tube 32 is provided at two locations, one by one installed on the sandblasting tube 311. In actual use, the purpose of this design is to adopt an interval installation so that hot sand and unheated cold sand are alternately evenly arranged, so that the alternation of hot and cold is achieved, so that the friction resistance of the torsion weight 23 is further increased; and the above-mentioned drill rod 400 and the torsion weight 23 are further prevented from slipping.

[0023] At the same time, in order to increase the sandblasting area, in the present embodiment, the friction part 3 also includes a rotary spraying assembly 33, which includes a rotary spraying head 331, a motor 332 and a fixed gear 333; one end of the rotary spraying head 331 is rotatably mounted at the nozzle of the sandblasting tube 311, and the fixed gear 333 is fixedly mounted on the outer wall of the rotary spraying head 331; the motor 332 is transmission-connected to the fixed gear 333, and drives the rotary spraying head 331 to rotate. In actual use, the purpose of this design is to achieve sandblasting in a larger range, so that more resistance can be added during the contact between the torsion weight 23 and the surface of the drill rod 400; in actual work, when the sand and gravel on the surface of the drill rod 400 first contact with the torsion weight 23, the sand and gravel will slide under the force and rotation of the drill rod 400, and then scratch the surface of the drill rod 400. In this way, when the torsion weight 23 is pushed against the surface of the drill rod 400 again, the friction resistance will increase, thereby making the tightening effect of the torsion weight 23 more stable.

[0024] In this embodiment, liquid is also injected into the sand box 312. In actual use, the liquid can be water; the purpose of this design is to achieve cooling and prevent the heat caused by the equipment from being transferred to the sand in the sand box 312.

[0025] In summary, this kind of rotational torque increasing drive device used for oil extraction is not only reasonably designed, but also simple to operate. It effectively replaces manual operation and avoids accidents. It can also increase torque. Therefore, the device is suitable for industry promotion.
