Description

Technical Field

[0001] This utility model relates to the field of seamless steel pipe processing technology, and in particular to a cooling water tank pipe laying device. Background Technology

[0002] Seamless steel pipes are made by piercing a whole round steel bar. They are steel pipes without weld seams on the surface. During the production process, seamless steel pipes are cooled by immersing in cold water after forming.

[0003] For example, a placement box for cooling seamless steel pipes in the prior art, with publication number CN215314781U, provides a better auxiliary device for the cooling process in the production of seamless steel pipes. Users can inject a certain amount of water into the device and place the steel pipe on the top surface of the support frame. When the reciprocating motor starts, the output end of the reciprocating motor drives the transmission rod to rotate, and the transmission rod will drive the support frame to move downward inside the cooling box through the thread action. A door panel is hinged on one side of the cooling box 1.

[0004] When using this device to cool down steel pipes, the steel pipes need to be placed manually on the top of the support frame. After the steel pipes have cooled down, there is no automatic structure to remove the pipes, which makes it inconvenient and inefficient for users to use the device. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art, and to propose a cooling water tank pipe laying device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cooling water tank pipe-laying device, comprising a cold water tank, a double cross shaft assembly rotatably connected inside the cold water tank, a support mechanism for placing steel pipes provided inside the double cross shaft assembly, an inlet line and an outlet line respectively provided on both sides of the cold water tank, and a transfer mechanism for transferring pipes installed on both the inlet line and the outlet line, the transfer mechanism including a mounting frame fixed to the inlet line or the outlet line, a horizontally distributed one-way threaded rod rotatably connected to the top of the mounting frame, a slider slidably connected to the mounting frame externally threaded to the one-way threaded rod, a hydraulic rod fixedly connected to the bottom of the slider, a pipe clamping groove plate fixedly connected to the telescopic end of the hydraulic rod, a two-way threaded rod rotatably connected to the inner side of the groove of the pipe clamping groove plate, two sliding plates slidably connected to the pipe clamping groove plate externally threaded to the two-way threaded rod, and insertion rods for inserting steel pipes fixedly connected to the opposite sides of the two sliding plates.

[0007] Preferably, the double cross shaft assembly includes a connecting shaft that is rotatably connected to the cold water tank, and crosses are symmetrically fixedly connected to both sides of the connecting shaft.

[0008] Preferably, the support mechanism includes four groups of placement shafts located between two cross-shaped frames. One group of placement shafts has three shafts and is distributed in a "pin" shape. Rotating plates are rotatably connected to the opposite ends of the two cross-shaped frames, and a pair of oppositely distributed rotating plates are respectively fixed to both ends of one group of placement shafts.

[0009] Preferably, motors are fixedly connected to one side of the pipe clamping groove plate, one side of the cold water tank, and one side of the mounting bracket.

[0010] Preferably, the main shaft of the motor located on one side of the pipe clamping groove plate is fixed to one end of the bidirectional threaded rod, the main shaft of the motor located on one side of the cold water tank is fixed to the center of the double cross-shaped shaft assembly, and the main shaft of the motor located on one side of the mounting bracket is fixed to the unidirectional threaded rod.

[0011] Preferably, pipe placement plates for placing steel pipes are provided on both the feeding line and the discharging line.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0013] 1.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] like Figure 1-4 As shown, a cooling water tank pipe-laying device includes a cold water tank 10. A double cross shaft assembly is rotatably connected inside the cold water tank 10. A support mechanism for placing steel pipes is provided inside the double cross shaft assembly. A feed line 1 and a discharge line 2 are respectively provided on both sides of the cold water tank 10. A transfer mechanism for transferring pipes is installed on both the feed line 1 and the discharge line 2. The transfer mechanism includes a mounting frame 15 fixed to the feed line 1 or the discharge line 2. A horizontally distributed one-way threaded rod 9 is rotatably connected to the top of the mounting frame 15. A slider 8 that is slidably connected to the mounting frame 15 is externally threaded to the one-way threaded rod 9. A hydraulic rod 7 is fixedly connected to the bottom of the slider 8. A pipe clamping groove plate 5 is fixedly connected to the telescopic end of the hydraulic rod 7. A two-way threaded rod 17 is rotatably connected to the inner side of the groove of the pipe clamping groove plate 5. Two sliding plates 16 that are slidably connected to the pipe clamping groove plate 5 are externally threaded to the two-way threaded rod 17. Insert rods 4 for inserting into steel pipes are fixedly connected to the opposite sides of the two sliding plates 16.

[0023] In this technical solution, the hydraulic rod 7 controls the lifting and lowering of the clamping groove plate 5, and in conjunction with the one-way threaded rod 9, drives the slider 8 to slide horizontally on the mounting frame 15. This allows the steel pipe to be transferred from the pipe placement plate 3 of the feeding line 1 to the support mechanism, or from the support mechanism to the pipe placement plate 3 of the discharge line 2, without any manual contact. In addition, the bidirectional threaded rod 17 inside the clamping groove plate 5 rotates, causing the two side slide plates 16 to move towards each other, so that the insertion rod 4 is inserted into the holes at both ends of the steel pipe, achieving precise fixation.

[0024] like Figure 2As shown, the double cross-axis assembly includes a connecting shaft 11 rotatably connected to the cold water tank 10. Symmetrically fixed to both sides of the connecting shaft 11 are cross members 14. The support mechanism includes four groups of placement shafts 12 located between the two cross members 14. One group of placement shafts 12 has three and is distributed in a "pin" shape. Rotating plates 13 are rotatably connected to the opposite ends of the two cross members 14. A pair of relatively distributed rotating plates 13 are respectively fixed to both ends of one group of placement shafts 12.

[0025] In this technical solution, the connecting shaft 11 rotates, driving the cross member 14 to rotate, realizing the up and down flipping of the support mechanism in the cold water tank 10. After the steel pipe is immersed in water for cooling, it moves to near the discharge line 2. And, each group of three is distributed in a "pin" shape, and both ends are rotatably connected to the cross member 14 through the rotating plate 13 for lifting the steel pipe. When the cross member 14 rotates, the steel pipe is kept balanced through the adaptive rotation of the rotating plate 13 to avoid slipping.

[0026] As Figure 1-3 shown, motors 6 are fixedly connected to one side of the pipe clamping groove plate 5, one side of the cold water tank 10, and one side of the mounting frame 15. The main shaft of the motor 6 on one side of the pipe clamping groove plate 5 is fixedly connected to one end of the bidirectional threaded rod 17. The main shaft of the motor 6 on one side of the cold water tank 10 is fixedly connected to the center of the double cross-axis assembly. The main shaft of the motor 6 on one side of the mounting frame 15 is fixedly connected to the unidirectional threaded rod 9.

[0027] In this technical solution, the motor 6 (which can use a stepper motor) on one side of the pipe clamping groove plate 5 is used to drive the bidirectional threaded rod 17 to rotate. The motor 6 (which can use a gear reduction motor) on one side of the cold water tank 10 is used to drive the double cross-axis assembly to rotate (the main shaft of this motor 6 is fixedly connected to the end of the connecting shaft 11). The motor 6 (which can use an AC asynchronous motor) on one side of the mounting frame 15 is used to drive the unidirectional threaded rod 9 to rotate.

[0028] As Figure 1 shown, pipe placement plates 3 for placing steel pipes are provided on both the feeding line 1 and the discharge line 2.

[0029] Working principle: The steel pipe is placed on the pipe placement plate 3 of the feeding line 1. The motor 6 on one side of the mounting frame 15 drives the unidirectional threaded rod 9 to rotate, driving the slider 8 to horizontally move above the feeding line 1. The hydraulic rod 7 extends to lower the pipe clamping groove plate 5. The motor 6 on one side of the pipe clamping groove plate 5 drives the bidirectional threaded rod 17 to rotate, driving the slide plate 16 to insert the inserting rods 4 into the holes at both ends of the steel pipe to fix the steel pipe. Subsequently, the hydraulic rod 7 contracts and the unidirectional threaded rod 9 rotates in the reverse direction to transfer the steel pipe to the support mechanism in the cold water tank 10. The motor 6 on one side of the cold water tank 10 drives the connecting shaft 11 to drive the cross member 14 to rotate, causing the support mechanism to flip and immerse the steel pipe in water for cooling. After cooling is completed, it flips again to near the discharge line 2. The transfer mechanism on the discharge line 2 transfers the steel pipe from the support mechanism to the pipe placement plate 3 of the discharge line 2 in the same process, completing the cooling process.

[0030] The wiring diagrams of the motor 6 and hydraulic rod 7 in this utility model are common knowledge in the field, and their working principle is a well-known technology. The appropriate model is selected according to actual use, so the control method and wiring layout will not be explained in detail.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
