[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] Please also read Figures 1 to 10 Now, a drill rod production line provided by the present invention is described. The drill rod production line comprises a processing area 1, in which a feeding device 2, a turning device (not shown in the figure), a friction welding device (not shown in the figure), a heat preservation device 3 and a feeding device 4 are sequentially arranged; the feeding device 2 and the feeding device 4 are respectively arranged at the two ends of the processing area 1, the turning device, the friction welding device and the heat preservation device 3 are all arranged on one side of the processing area 1, the processing area 1 is provided with a support frame 6 for supporting the drill rod 5 at the position of the turning device and the friction welding device, and the processing area 1 is provided with a conveying frame 7 for conveying the drill rod 5 at the position of the heat preservation device 3; trusses 8 are respectively arranged on both sides of the processing area 1, and the length direction of the trusses 8 is arranged along the arrangement direction of each device; a horizontal component 81 is slidably arranged on the two trusses 8, and a moving frame 82 is slidably arranged on the horizontal component 81, and the moving frame 82 has a vertical component 83 sliding along the height direction, and the bottom end of the vertical component 83 has a manipulator 9 for grabbing the drill rod 5. The driving method for the horizontal component 81 to slide on the truss 8, the driving method for the movable frame 82 to slide on the horizontal component 81, and the driving method for the vertical component 83 to slide on the movable frame 82 are all prior arts and will not be described in detail here.

[0020] The present invention provides a drill rod 5 production line. Compared with the prior art, the feeding device 2 is used to place a plurality of drill rods 5. The manipulator 9 grabs one of the drill rods 5 from the feeding device 2 each time and places the drill rod 5 on the support frame 6 at the turning device position. Then the operator fixes one end of the drill rod 5 on the chuck of the turning device and drives the drill rod 5 to rotate through the chuck to turn the end face of the drill rod 5. During the turning process, the support frame 6 supports the drill rod 5. After the turning is completed, the operator unloads the drill rod 5 and transfers the drill rod 5 to the support frame 6 at the friction welding device position through the manipulator 9. After the operator positions and clamps the drill rod 5, the threaded part is fixed to the drill rod 5 by friction welding. After the friction welding is completed, the manipulator 9 transfers the drill rod 5 to the conveying frame 7. The conveying frame 7 can convey the drill rod 5 so that the drill rod 5 moves from one end of the heat preservation device 3 to the other end. After the drill rod 5 stays in the heat preservation device 3 for a preset time, it is removed from the heat preservation device 3. It moves out of the insulation equipment 3 and then falls onto the unloading device 4 to complete the processing of the drill rod 5; it should be noted that after the turning equipment completes the processing of the drill rod 5, the drill rod 5 is transferred to the friction welding equipment by the manipulator 9, and then the manipulator 9 moves backward and transfers one of the drill rods 5 of the feeding device 2 to the turning equipment position. At this time, the turning equipment and the friction welding equipment can be processed at the same time; after the friction welding equipment is processed, the manipulator 9 transfers the drill rod 5 to the position of the insulation equipment 3; after the turning equipment is processed, the manipulator 9 transfers the drill rod 5 to the friction welding equipment, and then the manipulator 9 moves backward and transfers one of the drill rods 5 of the feeding device 2 to the turning equipment position. At this time, the turning equipment, the friction welding equipment and the insulation equipment 3 can be processed at the same time; through the above-mentioned settings of the present application, the positional relationship between the turning equipment, the friction welding equipment and the insulation equipment 3 can be optimized, the time for transferring the drill rod 5 between the various devices can be reduced, and the overall processing efficiency can be improved.

[0021] In some embodiments, Figures 1 to 10 As shown, one side of the heat preservation device 3 is provided with an avoidance groove 31 for avoiding the drill rod 5, and the two ends of the heat preservation device 3 are respectively provided with an inlet 32 ​​for the drill rod 5 to enter and an outlet 33 for the drill rod 5 to move out of the heat preservation device 3; wherein, both ends of the heat preservation device 3 and the side with the avoidance groove 31 are provided with high temperature resistant fabric (not shown in the figure), and the high temperature resistant fabric is used to shield the inlet 32, the outlet 33 and the avoidance groove 31, and does not affect the drill rod 5 to enter and move out of the heat preservation device 3.

[0022] It should be noted that the insulation device 3 has an insulation chamber, the inner wall of which is provided with an electric furnace wire and a thermocouple for temperature measurement, which can ensure that the insulation chamber is within a preset temperature range and that the welding position of the drill rod 5 is kept warm within the preset temperature range.

[0023] Exemplarily, by providing high temperature resistant fabrics at the inlet 32, outlet 33 and avoidance groove 31 of the heat preservation device 3, the inlet 32, outlet 33 and avoidance groove 31 can be shielded without affecting the drill rod 5, thereby reducing heat loss.

[0024] In some embodiments, Figures 1 to 10 As shown, the conveying frame 7 includes a frame body 71 and a conveying chain 72 rotatably arranged on the frame body 71, each link of the conveying chain 72 is provided with a limiting component 73, and the top of each limiting component 73 is provided with a V-shaped groove for supporting the drill rod 5; there are at least two conveying chains 72 on the frame body 71.

[0025] It should be noted that sprockets are rotatably provided on the frame 71 at the two ends of the conveying chain 72, and the conveying chain 72 is meshed with the sprockets; the sprockets corresponding to the two sides of the frame 71 are connected by a transmission shaft, and the frame 71 is also provided with a driving motor for driving the transmission shaft to rotate, and a chain transmission is used between the driving motor and the transmission shaft; the rotation of the conveying chain 72 can drive the drill rod 5 to move, thereby facilitating the drill rod 5 to move from one end of the insulation equipment 3 to the other end; by providing a limiting component 73 on the conveying chain 72 and providing a V-shaped groove on the limiting component 73, the drill rod 5 can be limited, and during the transportation of the drill rod 5, the drill rod 5 can be kept in a relatively stable state.

[0026] In some embodiments, Figures 1 to 10 As shown, the unloading device 4 is arranged at the discharge end of the conveying frame 7, and the unloading device 4 includes a unloading frame 41, a support plate 42 and an angle adjustment structure; the unloading frame 41 has a feed bracket 411 and a discharge bracket 412; the feed bracket 411 is located at the discharge end of the conveying frame 7, and the top of the feed bracket 411 has at least two step surfaces 413; one end of the support plate 42 is hinged on the feed bracket 411, and the other end extends downward to the position of the discharge bracket 412; the angle adjustment structure is connected to the discharge bracket 412; the angle adjustment structure includes a lifting end hinged to the lower end of the support plate 42.

[0027] It should be noted that, by providing a step surface 413 on the feed bracket 411, the drill rod 5 dropped from the conveyor frame 7 can roll downward along the multiple step surfaces 413 and finally fall onto the push plate; by adjusting the inclination angle of the support plate 42, the rolling speed of the drill rod 5 on the support plate 42 can be slowed down, thereby reducing the impact of the collision between the drill rods 5; through the above-mentioned arrangement, the drill rod 5 can be rolled into place at a slower speed, reducing the collision energy of the drill rod 5; when the cross-section of the drill rod 5 is polygonal or circular, the inclination of the support plate 42 can be adjusted by the angle adjustment structure, so that the polygonal drill rod 5 or the circular drill rod 5 can roll on the support plate 42.

[0028] Exemplarily, the step surfaces 413 on the feed support 411 are all inclined surfaces, and the inclined surfaces are inclined toward the support plate 42 , so that the drill rod 5 can roll down the inclined surface from high to low and finally fall onto the support plate 42 .

[0029] In some embodiments, Figures 1 to 10 As shown, the angle adjustment structure includes a shell 43, a worm wheel 44, a worm 45 and a screw 46; the shell 43 is connected to the top of the discharge bracket 412; the worm wheel 44 is rotatably arranged in the shell 43; a threaded hole is provided on the worm wheel 44; the worm 45 is meshed with the worm wheel 44, and one end of the worm 45 extends out of the shell 43; the screw 46 is threadedly matched with the worm wheel 44, and the bottom end of the screw 46 is hinged to the lower end of the support plate 42; the lower end of the support plate 42 is provided with a slot 421, and the support plate 42 is plugged and matched with the discharge bracket 412 through the slot 421.

[0030] It should be noted that when the worm 45 is rotated, the worm 45 can drive the worm wheel 44 to rotate, thereby causing the screw 46 to slide along its own axial direction to adjust the height of the lower end of the support plate 42, thereby adjusting the inclination of the support plate 42; through the cooperation of the worm wheel 44 and the worm 45, the purpose of self-locking can be achieved to prevent the lower end of the support plate 42 from falling automatically; the lower end of the support plate 42 is plugged into and matched with the discharge bracket 412 through the slot 421, and the inner side of the slot 421 is in contact with the outer side of the discharge bracket 412, which can play a guiding role and reduce the left and right shaking of the support plate 42.

[0031] Exemplarily, the lower end of the support plate 42 has a strip groove 422, and the screw rod 46 has a pin hole near the bottom end, and a pin shaft 423 is inserted into the pin hole. The two ends of the pin shaft 423 are respectively located in the strip grooves 422 on both sides of the slot 421; the outer peripheral wall of the pin shaft 423 contacts the top wall and the bottom wall of the slot 421; through the above arrangement, when the screw rod 46 drives the support plate 42 to rise and fall, the pin shaft 423 can slide in the strip groove 422 according to actual conditions. The pin shaft 423 and the pin hole are interference fit.

[0032] In some embodiments, Figures 1 to 10 As shown, the manipulator 9 includes two clamping jaws 91, a gear 92 and two racks 93; the two clamping jaws 91 are slidably arranged at the bottom end of the vertical component 83; each clamping jaw 91 has two clamping grooves 911, and the clamping grooves 911 on the two clamping jaws 91 can clamp the drill rod 5; the gear 92 is rotatably arranged at the bottom end of the vertical component 83; the vertical component 83 has a driving motor inside to drive the gear 92 to rotate; the two racks 93 are both engaged with the gear 92, and the two racks 93 are arranged opposite to each other; the two racks 93 correspond to the two clamping jaws 91 one by one, and are respectively connected to the corresponding clamping jaws 91; wherein, when the gear 92 rotates, the two clamping jaws 91 slide relative to each other or slide away from each other under the drive of the rack 93.

[0033] It should be noted that, through the rotation of the gear 92, the two racks 93 can be driven to move in opposite directions, so that the two jaws 91 can complete the grasping and releasing actions; through the above-mentioned setting of the manipulator 9, the two clamps can clamp the drill rod 5 and place the drill rod 5 at the specified position, thereby improving the transportation efficiency of the drill rod 5 and improving the overall efficiency of the drill rod 5 production.

[0034] Exemplarily, the side of the clamp 91 has a T-shaped slot, and the vertical component 83 has a T-shaped slide rail. The clamp 91 cooperates with the T-shaped slide rail through the T-shaped slot to limit the height direction of the clamp 91 and guide the sliding direction of the clamp 91.

[0035] In some embodiments, Figures 1 to 10 As shown, the feeding device 2 includes a frame 21, a plurality of material storage racks 22 and a support belt 23; the top of the frame 21 is provided with a tilted feeding platform; the plurality of material storage racks 22 are all provided on the side of the frame 21 at the high end of the feeding platform, and are spaced along the length direction of the frame 21; each material storage rack 22 is provided with a column 24, the height of the top of the column 24 is higher than the height of the high end of the feeding platform; there is a space between adjacent columns 24; one side of the frame 21 is provided with a baffle 25 for contacting the end of the drill rod 5; one end of the support belt 23 is connected to the column 24, and the height of the connection position is higher than the height of the high end of the feeding platform; a reversing roller 26 is provided at the high end of the feeding platform, the other end of the support belt 23 bypasses the reversing roller 26 and is connected to the output shaft of the driving structure, and the height of the driving structure is lower than the height of the reversing roller 26; the total width of the support belt 23 and a single column 24 is less than the distance between two adjacent fork claws on the forklift. The driving structure can drive the motor.

[0036] It should be noted that a number of drill rods 5 are lifted to the top of the column 24 by a forklift, and then the forklift moves forward to make the drill rod 5 pass over the column 24 and be located directly above the storage rack 22, and then the drill rod 5 is placed downward until the drill rod 5 contacts the storage rack 22, and the fork claws of the forklift continue to descend and separate from the drill rod 5. At this time, the loading process is completed, and the forklift moves backward and leaves the storage rack 22; the output shaft of the drive structure winds up the support belt 23, which can gradually tighten the support belt 23 and finally straighten the support belt 23. At this time, the support belt 23 forms an inclined surface, and the drill rod 5 moves along the support belt 23 to the loading platform; the baffle 25 on one side of the frame 21 can limit the drill rod 5. Through the above-mentioned arrangement of the present application, the movement and position of the drill rod 5 can be effectively controlled, reducing the difficulty in controlling the drill rod 5 when it rolls off the forklift, thereby reducing safety hazards.

[0037] In some embodiments, Figures 1 to 10As shown, the material storage rack 22 has a support surface 221 inclined toward the column 24, and the lower end of the support surface 221 is located at the position of the column 24; wherein, a weight 27 is connected to the support belt 23, and in the initial state, under the gravity of the weight 27, the lowest position of the support belt 23 is lower than the lower end position of the support surface 221. The weight 27 is connected to the support belt 23 through a U-shaped piece 271, and the weight 27 can slide on the support belt 23 through the U-shaped piece 271; both ends of the U-shaped piece 271 have external threads, and both ends of the U-shaped piece 271 pass through the weight 27 and are connected by nuts.

[0038] It should be noted that the support surface 221 is inclined toward the column 24. When a number of drill rods 5 are placed on the storage rack 22, the drill rods 5 will be piled up near the column 24. Through the above-mentioned arrangement, the situation where the drill rods 5 move to the frame 21 can be reduced. By arranging a weight 27 on the support belt 23, when there is no drill rod 5 on the support belt 23, the support belt 23 will automatically sag under the action of the weight 27, thereby facilitating the lowest position of the support belt 23 to drop below the lowest position of the storage rack 22.

[0039] In some embodiments, Figures 1 to 10 As shown, the loading platform includes a plurality of loading plates 28 arranged at intervals along the length of the frame 21, the top of the loading plate 28 is an inclined surface, and the reversing roller 26 is located at the high end position of the top of the loading plate 28; wherein, a stop component 29 is provided at the low end position of each loading plate 28, the top of the stop component 29 has an inclined surface, the stop component 29 is used to contact the drill rod 5 on the side of the high end of the inclined surface, and the low end position of the inclined surface has a stop block 291; the frame 21 is provided with a pushing mechanism for pushing the drill rod 5 at the lowest position, so that the drill rod 5 moves from the high end of the stop component 29 to the stop block 291 position.

[0040] It should be noted that a number of loading plates 28 form a loading platform, and when the drill rod 5 moves to the top of the loading plate 28, the drill rod 5 moves on the inclined surface at the top of the loading plate 28; the stop member 29 at the lower end of the loading plate 28 can limit the drill rod 5 to prevent the drill rod 5 from slipping off the loading plate 28; after the manipulator 9 grabs the drill rod 5 at the position of the stop block 291, the pushing mechanism pushes the drill rod 5 in contact with the stop member 29, and pushes the drill rod 5 to the top of the stop member 29. At this time, the drill rod 5 can move from the high end of the top of the stop member 29 to the low end, and finally stop at the position of the stop block 291; the above process is repeated, so that the manipulator 9 can grab one of the drill rods 5 at a time.

[0041] In some embodiments, Figures 1 to 10As shown, the pushing mechanism includes a pushing component 211 and a first power structure; the pushing component 211 is slidably arranged on one side of the loading plate 28, and is located at the position where the stop component 29 is connected to the drill rod 5; the first power structure is arranged on the frame 21; the driving end of the first power structure is connected to the pushing component 211, and is used to drive the pushing component 211 to slide up and down; wherein, when the pushing component 211 is pushed into place, the drill rod 5 in contact with the stop component 29 can move to the high end of the stop component 29, and move along the inclined surface of the stop component 29 to the position of the stop block 291.

[0042] It should be noted that a guide rail 281 is provided on the loading plate 28, and a slide groove slidably matched with the guide rail 281 is provided on the pushing component 211; the first driving structure provides power to the pushing component 211, so that the pushing component 211 can contact with the drill rod 5 and lift the drill rod 5, or the pushing component 211 can be reset downward and separated from the drill rod 5; through the above-mentioned arrangement, the pushing of a single drill rod 5 can be realized at a time, which is convenient for the manipulator 9 to grab one of the drill rods 5.

[0043] Exemplarily, the guide rail 281 is a wedge-shaped guide rail, and the slide groove is a wedge-shaped groove.

[0044] In some embodiments, Figures 1 to 10 As shown, the first power structure includes a driving shaft 212 and a cam 213 . The driving shaft 212 is rotatably matched with the frame 21 . The cam 213 is connected to the driving shaft 212 . The outer peripheral wall of the cam 213 contacts the bottom of the pushing component 211 .

[0045] It should be noted that the drive shaft 212 passes through several loading plates 28, and the drive shaft 212 is connected to the cam 213 of each loading plate 28; a servo motor connected to the drive shaft 212 is provided on the frame 21; after the drive shaft 212 rotates, it can drive several cams 213 to rotate at the same time, and finally make several pushing components 211 push the drill rod 5 synchronously, and push the drill rod 5 to the top position of the stop component 29.

[0046] In some embodiments, Figures 1 to 10 As shown, the frame 21 has a horizontal plate 214 above the loading platform, and a guide plate 215 is provided on the horizontal plate 214. The bottom of the guide plate 215 is parallel to the top of the loading plate 28, and the distance between the guide plate 215 and the loading plate 28 is slightly larger than the diameter of the drill rod 5, so that the drill rod 5 can slide between the guide plate 215 and the loading plate 28. Through the above arrangement, the drill rod 5 can be height-limited.

[0047] Exemplarily, the lowest position of the guide plate 215 is located at the position of the second-to-last drill rod 5 on the loading plate 28, that is, the second drill rod 5 from the bottom to the top on the loading plate 28; through the above arrangement, the guide plate 215 will not affect the pushing mechanism from pushing the first-to-last drill rod 5.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
