Description

Technical Field

[0001] The utility model relates to the technical field of metal processing and manufacturing, in particular to a water spray device for quenching a sucker rod. Background Art

[0002] The sucker rod is the main force-bearing component in the oil production process of the oil well. During the processing, it needs to be heat treated by medium frequency quenching equipment to improve the hardness and wear resistance of the sucker rod. During the quenching process, the rod needs to be cooled by a water spray device. The existing water spray assembly generally sets a water inlet pipe, a connecting pipe and a water spray barrel. The sucker rod moves forward through the roller and enters the water spray barrel. The cooling medium enters the water spray barrel through the water inlet pipe. The cooling medium is sprayed onto the rod through the water spray hole of the water spray barrel on the inner wall of the water spray barrel. The cooling medium in the water spray barrel can completely submerge the rod body, so that it is cooled evenly and is not easy to generate thermal stress, etc., to prevent the rod body from deformation or insufficient local hardness.

[0003] However, during actual use of the above-mentioned equipment, when the cooling water directly enters the water spray barrel quickly through the connecting pipe, the cooling water can only be sprayed onto the surface of the rod through a small number of water spray holes close to the connecting pipe, resulting in the cooling water being unable to completely cool the surface of the rod at the beginning, and further resulting in the inability to completely achieve uniform cooling of the rod surface, affecting the quenching effect of the sucker rod. In view of this, we propose a water spray device for quenching sucker rods. Summary of the invention

[0004] The utility model aims to provide a water spray device for quenching a sucker rod, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a water spray device for quenching a sucker rod, comprising a water inlet pipe, a connecting pipe is fixedly installed at the bottom end of the water inlet pipe, a hollow tube is fixedly installed at the bottom end of the connecting tube, a water spray hole is opened on the inner wall surface of the hollow tube, a sealing assembly is arranged inside the hollow tube, and the sealing assembly comprises:

[0006] A fixed frame, the fixed frame is fixedly mounted on the right side surface of the hollow tube, an electric push rod is fixedly mounted on the right inner wall surface of the fixed frame, the left end of the electric push rod penetrates through the right side surface of the hollow tube and a moving ring plate is fixedly mounted thereon, and when the electric push rod is started, the moving ring plate can be driven to move linearly in the left and right directions;

[0007] A moving cylinder, wherein the moving cylinder is fixedly mounted on the left side surface of the moving ring plate, and when the moving ring plate moves, the moving cylinder can be driven to move synchronously, and a through hole is opened on the outer wall surface of the moving cylinder;

[0008] A moving cavity is provided in the inner wall of the moving cylinder, a spring is fixedly installed on the inner surface of the moving cavity close to the outer wall of the moving cylinder, a limiting plate is fixedly installed on one end of the spring close to the inner wall of the moving cylinder, the limiting plate can squeeze the spring when it moves toward the spring, so that the spring is compressed to generate elastic potential energy, a conical block is fixedly installed on the side surface of the limiting plate away from the spring, and the conical block can drive the limiting plate to move synchronously when it moves.

[0009] Preferably, the inner wall of the moving cylinder fits with the surface of the inner wall of the hollow tube, and the hollow tube can limit the movement of the moving cylinder so that the moving cylinder can only move linearly in the left and right directions.

[0010] Preferably, the outer wall of the movable ring plate fits with the inner wall of the hollow tube.

[0011] Preferably, the outer wall of the limit plate fits with the inner wall of the movable cavity, and the inner wall of the movable cavity can limit the movement of the limit plate, so that the limit plate can only move linearly inside the movable cavity.

[0014] Compared with the prior art, the utility model provides a water spray device for quenching a sucker rod, which has the following beneficial effects:

[0015] 1. The water spray device for quenching the sucker rod can seal the water spray hole before cooling the sucker rod through the cooperation of the set fixing frame, the electric push rod, the movable ring plate, the movable cylinder and the through hole. When the cooling water fills the inside of the hollow tube, the cooling water is sprayed out after passing through all the water sprays, so as to evenly cool the surface of the rod, and avoid that the cooling water can only be sprayed to part of the surface of the rod through the water spray hole on the upper part when the cooling water directly enters the inside of the hollow tube quickly through the connecting pipe, which affects the uniformity of cooling the surface of the rod at the beginning. Moreover, through the cooperation of the set movable cavity, the spring, the limit plate and the conical block, when the movable cylinder seals the water spray hole, the impurities remaining in the water spray hole when the cooling water passes through can be ejected and cleaned, so as to avoid that the impurities are blocked in the water spray hole and affect the uniform cooling effect of the rod next time.

[0016] 2. The water spray device for quenching the sucker rod can enhance the sealing effect of the movable ring plate on the right end of the hollow tube by means of the provided rubber ring, thereby preventing the cooling water from leaking through the gap between the electric push rod and the inner wall of the hollow tube, and by means of the provided air holes, preventing the formation of a sealed space inside the movable cavity, thereby affecting the movement of the conical block and the cleaning effect inside the water spray hole.

DETAILED DESCRIPTION

[0022] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a water spray device for quenching a sucker rod, comprising a water inlet pipe 1, a connecting pipe 2 is fixedly installed at the bottom end of the water inlet pipe 1, a hollow tube 3 is fixedly installed at the bottom end of the connecting pipe 2, cooling water can enter the interior of the hollow tube 3 through the connecting pipe 2, a water spray hole 4 is opened on the inner wall surface of the hollow tube 3, and the cooling water entering the hollow tube 3 can be discharged through the water spray hole 4 and sprayed onto the rod member, the cooling medium in the hollow tube 3 can completely submerge the rod body, so that it is cooled evenly and is not easy to generate thermal stress, etc., and a sealing component is arranged inside the hollow tube 3.

[0023] The sealing assembly includes: a fixed frame 501, a moving cylinder 504 and a moving chamber 506. The fixed frame 501 is fixedly installed on the right side surface of the hollow tube 3. An electric push rod 502 is fixedly installed on the right inner wall surface of the fixed frame 501. The left end of the electric push rod 502 passes through the right side surface of the hollow tube 3 and is fixedly installed with a moving ring plate 503. The outer wall of the moving ring plate 503 fits the inner wall of the hollow tube 3. The moving cylinder 504 is fixedly installed on the left side surface of the moving ring plate 503. The inner wall of the moving cylinder 504 fits the surface of the inner wall of the hollow tube 3. A through hole 505 is opened on the outer wall surface of the moving cylinder 504. The size of the through hole 505 is the same as that of the water spray hole 4. The electric push rod 502 passes through the right side surface of the hollow tube 3 and is fixedly installed with a moving ring plate 503. The outer wall of the moving cylinder 504 fits the surface of the inner wall of the hollow tube 3. When the push rod 502 is started, the moving cylinder 504 can be driven to move linearly in the left and right directions by moving the ring plate 503. When the electric push rod 502 drives the moving cylinder 504 to move to the left, the moving cylinder 504 can seal the water spray hole 4. When the cooling water fills the interior of the hollow tube 3, the electric push rod 502 can be started to drive the moving cylinder 504 to move to the right, so that the through hole 505 is aligned with the water spray hole 4. At this time, the cooling water can be completely sprayed onto the surface of the rod through the water spray hole 4, avoiding the cooling water directly entering the hollow tube 3 through the connecting pipe 2. If the flow rate is too fast, it can only be sprayed through part of the water spray hole 4 to reach the surface of the rod, which will still cause the surface of the rod to not be cooled evenly.

[0024] The movable ring plate 503 can perform sealing treatment on the right end of the movable ring plate 503 to prevent the cooling water from leaking through the gap between the electric push rod 502 and the inner wall of the hollow tube 3 .

[0025] The movable cavity 506 is opened in the inner wall of the movable cylinder 504, and a spring 507 is fixedly installed on the surface of one side of the movable cavity 506 close to the outer wall of the movable cylinder 504. A limiting plate 508 is fixedly installed on one end of the spring 507 close to the inner wall of the movable cylinder 504. The outer wall of the limiting plate 508 fits the inner wall of the movable cavity 506. A conical block 509 is fixedly installed on the surface of the limiting plate 508 away from the spring 507. The limiting plate 508 can keep the movement of the conical block 509 vertical, and at the same time can prevent the conical block 509 from detaching from the movable cavity 506, making it difficult to reset and affecting the use of the sealing component. The front side cross-sectional surface of the conical block 509 is an isosceles trapezoidal structure. When the movable cylinder 504 moves to the right to open the water spray hole 4, it will drive the conical block 509 to move synchronously. When the conical block 509 moves to the right, the inner wall of the water spray hole 4 will squeeze the conical block 509. At this time, the conical block 509 will move along its own inclined surface toward the inside of the movable cavity 506, and squeeze the spring 507 to generate elastic potential energy. When the movable cylinder 504 moves to the left to seal the water spray hole 4, the conical block 509 will move into the water spray hole 4 under the action of the elastic potential energy of the spring 507 to push out the impurities inside the water spray hole 4 when the cooling water passes through the water spray hole 4, so as to prevent the impurities from clogging the water spray hole 4 and affecting the outflow of cooling water.

[0026] A rubber ring 601 is fixedly installed on the right side surface of the movable ring plate 503, and the outer wall surface of the rubber ring 601 fits with the surface of the inner wall of the hollow tube 3. The rubber ring 601 can seal the gap between the movable ring plate 503 and the inner wall of the hollow tube 3 due to production accuracy problems, thereby further enhancing the sealing effect of the movable ring plate 503. An air vent 602 is provided on the outer wall surface of the movable cavity 506. The air vent 602 allows the interior of the movable cavity 506 to be connected with the interior of the hollow tube 3, so that the gas inside the movable cavity 506 can be discharged through the air vent 602, thereby avoiding the formation of a closed space inside the movable cavity 506, resulting in the formation of negative pressure inside the movable cavity 506 when the conical block 509 moves out of the movable cavity 506, thereby hindering the movement of the conical block 509 and the use effect of the conical block 509.

[0027] In the present invention, when in use, before the sucker rod needs to be cooled, the electric push rod 502 can be started to drive the moving cylinder 504 to move to the left, so that the inner wall of the moving cylinder 504 can seal the water spray hole 4. When the cooling water fills the inside of the hollow tube 3, the electric push rod 502 can be started to drive the moving cylinder 504 to move to the right, so that the through hole 505 can be aligned with the water spray hole 4, so that the cooling water can be sprayed onto the surface of the rod through all the water spray holes 4. At this time, the surface of the rod can be completely cooled and the temperature can be reduced, avoiding the cooling water directly passing through the connecting The connecting pipe 2 enters the inner wall of the hollow tube 3, resulting in that only part of the water can be sprayed onto the surface of the rod through the water spray hole 4, which leads to uneven cooling. After cooling is completed, the electric push rod 502 can be started to drive the moving cylinder 504 to move to the left to move the water spray hole 4 again. During the movement, the conical block 509 will move out of the moving cavity 506 under the action of the elastic potential energy of the spring 507, and be pushed out to the inside of the water spray hole 4. At this time, the conical block 509 will push out the impurities remaining in the water spray hole 4 when the cooling water passes through, so as to prevent the impurities from clogging the water spray hole 4 and affecting the next cooling process.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
