Description

Technical Field

[0001] This utility model relates to the field of drill pipe processing technology, and in particular to a conveyor cooling bed. Background Technology

[0002] The raw materials used in the production of trenchless drill pipes are seamless steel pipes of various specifications. These pipes undergo multiple processing steps, the main processes of which include sawing, thickening, heat treatment, straightening, mechanical property testing, non-destructive testing, thread machining, thread non-destructive testing, and thread parameter testing. Among these, tempering is a crucial step in further optimizing drill pipe performance. Tempering involves heating the quenched drill pipe to a lower temperature, holding it at that temperature for a period of time, and then cooling it. This process eliminates the internal stress generated during quenching, improving the drill pipe's toughness and fatigue resistance.

[0003] However, the tubes that have just come out of the tempering furnace can reach 640°C, which increases the difficulty of feeding. In addition, during the natural cooling process, it is necessary to ensure that each tube dissipates heat evenly in a limited space in order to ensure that each tube forms normal structural changes. Furthermore, the tubes that are left to cool are prone to bending during the cooling process, which affects the final forming quality of the tubes. Therefore, technical improvements are required. Utility Model Content

[0004] The purpose of this utility model is to provide a conveying cooling bed to solve the problems mentioned in the background art, so as to enable the orderly conveying and cooling of the tube material coming out of the tempering furnace and ensure the processing quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A conveying cooling bed includes a tempering discharge rack, a discharge rack, a slow cooling rack, a first transfer assembly, and a second transfer assembly, wherein:

[0007] The tempering discharge rack is used to receive the tube material output from the tempering furnace and drive the tube material to move axially.

[0008] The unloading rack is used to store cooled pipe materials;

[0009] The slow cooling rack is set between the tempering discharge rack and the unloading rack. The slow cooling rack is equipped with several rotating rollers arranged at intervals. A storage position for placing a tube is formed between two adjacent rotating rollers. Each tube is in its corresponding storage position without contacting each other and is driven to rotate by the rotating rollers.

[0010] The first material transfer assembly is used to drive the tubular material from the tempering discharge rack to the storage position at the beginning of the slow cooling rack;

[0011] The second material transfer assembly is used to drive the tubular material to gradually flow from the storage position at the beginning to the storage position at the end and finally transfer it from the slow cooling rack to the unloading rack.

[0012] As an optional solution, the second material transfer assembly includes a slide rail, a bracket, a lifting drive mechanism, and a translation drive mechanism, wherein:

[0013] The slide rails are arranged from the first storage position to the last storage position, and the slide rails are provided with grooves.

[0014] The bracket is slidably mounted in the groove, and the bracket is provided with a groove to restrict the rolling of the pipe material;

[0015] The lifting drive mechanism is used to drive the slide rail to rise or fall relative to the slow cooling rack, thereby lifting the tube above the storage position or placing the tube on the storage position;

[0016] The translation drive mechanism is used to drive the bracket to move back and forth relative to the slide rail, thereby translating the pipe material from above one storage position to above another storage position.

[0017] As an alternative, the lifting drive mechanism includes a fixed frame, a swing arm, and a first electric cylinder. The fixed frame is located below the slide rail. The middle part of the swing arm is hinged to the fixed frame. One end of the swing arm is rotatably connected to the bottom of the slide rail. The first electric cylinder is fixed on the fixed frame, and the output end of the first electric cylinder is rotatably connected to the other end of the swing arm.

[0018] As an alternative, the translation drive mechanism includes a second electric cylinder, which is fixed to the bottom of the slide rail. The bottom of the bracket is provided with a stroke block that extends out of the slide groove, and the output end of the second electric cylinder is connected to the stroke block.

[0019] As an alternative, the tubing is periodically rotated in both directions in the storage location.

[0020] As an alternative, the slow cooling rack includes a support frame, multiple rotating rollers mounted on the support frame, sprockets at both ends of the support frame, a chain connecting the sprockets at both ends, and a drive wheel on the axle of each rotating roller, with each drive wheel meshing with the chain for transmission.

[0021] As an optional solution, multiple support frames are provided, which are arranged in parallel and perpendicular to the tempering discharge rack. The sprockets at the same end of each support frame rotate synchronously through a connecting shaft, and any connecting shaft is driven to rotate by a motor.

[0022] As an optional solution, the tempering discharge rack is equipped with several conveying rollers and guide racks. The conveying rollers form a tube material conveying line. The first end of the guide rack is located above the tube material conveying line, and the second end of the guide rack is located above the storage position at the beginning. The first end of the guide rack is higher than the second end of the guide rack.

[0023] As an alternative, the first material transfer assembly includes a material-pushing plate rotatably mounted on the tempering discharge rack. The material-pushing plate is provided with a guide ramp. The material-pushing plate is used to lift the tube material away from the tube material conveying line and cause the tube material to roll down along the guide ramp to the first end of the guide rack.

[0024] As an alternative, the first end of the unloading rack extends above the storage position at the end to receive the tubular material output from the slow cooling rack, and the second end of the unloading rack is provided with a storage trough, with the first end of the unloading rack being higher than the second end of the unloading rack.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0040] Furthermore, the terms "first" and "second" are merely used to distinguish between different terms in description and do not have any special meaning.

[0041] Please see Figures 1 to 3 As shown, this embodiment provides a conveying cooling bed, including a tempering discharge rack 1, a discharge rack 2, a slow cooling rack 3, a first material transfer assembly 4, and a second material transfer assembly 5, wherein:

[0042] The tempering discharge rack 1 is used to receive the tube material output from the tempering furnace and drive the tube material to move axially.

[0043] The unloading rack 2 is used to store the cooled pipe material;

[0044] The slow cooling rack 3 is located between the tempering discharge rack 1 and the unloading rack 2. The slow cooling rack 3 is provided with several rotating rollers 31 arranged at intervals. A storage position 32 for placing a tube is formed between two adjacent rotating rollers 31. Each tube does not contact each other in the corresponding storage position 32 and is driven to rotate by the rotating rollers 31.

[0045] The first material transfer assembly 4 is used to drive the tubular material from the tempering discharge rack 1 to the storage position 32 at the beginning of the slow cooling rack 3;

[0046] The second material transfer component 5 is used to drive the tube material to gradually flow from the storage position 32 at the beginning to the storage position 32 at the end and finally transfer it from the slow cooling rack 3 to the unloading rack 2.

[0047] This enables the orderly flow and feeding of the tube material after it is output from the tempering furnace. During the process, the tube material is rotated and cooled in each storage position 32 on the slow cooling rack 3, which not only ensures uniform heat dissipation of the tube material, but also avoids bending of the tube material, thereby ensuring the consistency of the microstructure changes and the forming quality of the tube material during the tempering and cooling process.

[0048] Optionally, the second material transfer assembly 5 includes a slide rail 51, a bracket 52, a lifting drive mechanism, and a translation drive mechanism. The slide rail 51 is arranged from the first storage position 32 to the last storage position 32, and a groove is provided on the slide rail 51. The bracket 52 is slidably disposed in the groove, and a groove 53 is provided on the bracket 52 to restrict the rolling of the tube. The lifting drive mechanism is used to drive the slide rail 51 to rise or fall relative to the slow cooling rack 3, thereby lifting the tube above the storage position 32 or placing the tube on the storage position 32. The translation drive mechanism is used to drive the bracket 52 to move back and forth relative to the slide rail 51, thereby translating the tube from above one storage position 32 to above another storage position 32.

[0049] Therefore, by using the lifting motion of the slide rail 51 in conjunction with the forward and backward movement of the bracket 52, the tube material can be transferred from one storage position 32 on the slow cooling rack 3 to another storage position 32, i.e., to an adjacent storage position 32. The translation amount of the translation drive mechanism is the distance between the two adjacent storage positions 32, thereby realizing the orderly flow of the tube material on the slow cooling rack 3. When the cooled tube material leaves the slow cooling rack 3, new tube material is continuously added to ensure that each tube material can be cooled evenly.

[0050] Furthermore, the lifting drive mechanism includes a fixed frame 54, a swing arm 55, and a first electric cylinder 56. The fixed frame 54 is located below the slide rail 51. The middle part of the swing arm 55 is hinged to the fixed frame 54. One end of the swing arm 55 is rotatably connected to the bottom of the slide rail 51. The first electric cylinder 56 is fixed on the fixed frame 54. The output end of the first electric cylinder 56 is rotatably connected to the other end of the swing arm 55.

[0051] Thus, the first electric cylinder 56 extends and retracts to drive the swing arm 55 to swing, thereby driving the slide rail 51 to rise or fall, so as to accurately lift or lower the pipe material in the storage position 32 and help transfer the pipe material between different storage positions 32.

[0052] Furthermore, the translation drive mechanism includes a second electric cylinder 57, which is fixed to the bottom of the slide rail 51. The bottom of the bracket 52 is provided with a stroke block 58 that extends out of the slide groove, and the output end of the second electric cylinder 57 is connected to the stroke block 58.

[0053] Therefore, by using the second electric cylinder 57 to extend and retract, the bracket 52 moves back and forth, in conjunction with the lifting drive mechanism, to meet the action requirements during the transfer of pipe materials.

[0054] Optionally, the pipe is periodically rotated in and out of the storage position 32.

[0055] It should be noted that maintaining the rotation of the tube serves two purposes: firstly, it ensures ample contact between the tube surface and the air, enhancing heat dissipation; secondly, it helps to evenly release internal stress, preventing bending and deformation. However, continuous rotation in one direction can easily cause the tube to shift, affecting subsequent flow. Therefore, a periodic alternating forward and reverse rotation method is adopted to ensure uniform heat dissipation and effectively prevent tube shifting. Preferably, the rotation is switched between forward and reverse every 3 to 5 seconds.

[0056] Optionally, the slow cooling frame 3 includes a support frame 33, a plurality of rotating rollers 31 are mounted on the support frame 33, sprockets 34 are provided at both ends of the support frame 33, a chain 35 is connected between the sprockets 34 at both ends, and a drive wheel 36 is provided on the axle of each rotating roller 31, and each drive wheel 36 meshes with the chain 35 for transmission.

[0057] Thus, the chain 35 drives multiple drive wheels 36 to rotate, which in turn drives multiple rotating rollers 31 to rotate synchronously, meeting the requirement of synchronous rotation of each pipe.

[0058] Furthermore, multiple support frames 33 are provided, and the multiple support frames 33 are arranged in parallel and perpendicular to the tempering discharge rack 1. The sprockets 34 at the same end of each support frame 33 rotate synchronously through the connecting shaft 37, and any connecting shaft 37 is driven to rotate by the motor 38.

[0059] Therefore, multiple support frames 33 can improve the support of the pipe material, and the motor 38 drives the connecting shaft 37 to rotate, which drives the sprockets 34 on all support frames 33 to rotate synchronously, ensuring that each rotating roller 31 operates in a consistent manner and achieving uniform rotation of each pipe material.

[0060] Optionally, the tempering discharge rack 1 is provided with a number of conveying rollers 11 and guide racks 12. Each conveying roller 11 forms a tube material conveying line. The first end of the guide rack 12 is located above the tube material conveying line, and the second end of the guide rack 12 is located above the storage position 32 at the beginning end. The first end of the guide rack 12 is higher than the second end of the guide rack 12.

[0061] Thus, the axial conveying of the tube material is achieved through the conveying roller 11, and the connection between the tempering discharge rack 1 and the buffer rack is achieved through the guide rack 12, ensuring that the tube material is smoothly transferred to the storage position 32 at the beginning of the slow cooling rack 3.

[0062] Furthermore, the first material transfer assembly 4 includes a material-pushing plate 41 rotatably mounted on the tempering discharge rack 1. The material-pushing plate 41 is provided with a guiding ramp 42. The material-pushing plate 41 is used to lift the tube material away from the tube material conveying line and cause the tube material to roll down along the guiding ramp to the first end of the guide rack 12. Here, the material-pushing plate 41 is rotatably mounted on the tempering discharge rack 1, and by changing the rotation angle, the material-pushing and obstacle-avoiding functions can be switched.

[0063] Thus, the material is removed from the material conveying line by the action of the material feeding plate 41, and smoothly transitions to the material guide frame 12 along the material guide slope 42, ensuring that the material falls accurately into the storage position 32 at the beginning. The material transfer is completed with the shortest action, reducing operational errors and improving the overall circulation efficiency.

[0064] Optionally, the first end of the unloading rack 2 extends above the storage position 32 at the end to receive the tubular material output from the slow cooling rack 3, and the second end of the unloading rack 2 is provided with a storage trough 21, with the first end of the unloading rack 2 being higher than the second end of the unloading rack 2.

[0065] Therefore, the tube material on the storage position 32 at the end is received by the unloading rack 2, and the tube material slides down the unloading rack 2 to the storage tank 21 through the height difference, ensuring that the tube material is collected smoothly, avoiding secondary handling, further improving the unloading efficiency and optimizing the overall production process.

[0066] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
