Description

Technical Field

[0001] The invention relates to the technical field of drill rod processing, in particular to a drill rod heating and upsetting turnover device. Background Art

[0002] Drill pipe is a steel pipe with threads at the tail end, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or bottom hole device at the bottom of the well. During the use of the drill pipe, it must withstand huge internal and external pressure, twisting, bending and vibration, so the drill pipe blank is usually required to be upset. Through upsetting, the length of the drill pipe blank is reduced while the cross-section of the end is increased to strengthen the structural strength of the end of the drill pipe and ensure its service life.

[0003] In the prior art, the end of the drill rod needs to be heated before upsetting (usually by electromagnetic heating, inserting the end of the drill rod into the heating hole of a heater and heating it to about 1150°C), and then the heated end is upset, and the drill rod is kept warm in an environment of 300°C. Therefore, in the actual production process, the heater and the upsetting machine are usually placed close together so that the drill rod with the heated end can be quickly inserted into the upsetting hole of the upsetting machine for upsetting.

[0004] However, in the prior art, drill rods are usually carried manually and inserted into or extracted from heating machines and upsetting machines. Due to the heavy weight of the drill rods and the fact that they are usually processed in blanks, the workload of workers increases, affecting processing efficiency. Moreover, during the heating and upsetting process, the surface temperature of the drill rods is relatively high. Due to their heavy weight, if the operators are not careful, safety accidents such as scalding or smashing of the drill rods may easily occur, affecting the safety of the workers.

[0005] Therefore, it is necessary to provide a turnover device for heating and upsetting a drill rod. Summary of the invention

[0006] The purpose of the present invention is to overcome the defects in the prior art and provide a drill rod heating upsetting turnover device which can reduce the burden on workers, reduce labor costs, improve production efficiency and avoid worker safety accidents.

[0007] In order to achieve the above technical effects, the technical solution of the present invention is as follows: a drill rod heating and upsetting turnover device, comprising a frame, a slope arranged on the frame, and two turnover assemblies arranged at both ends of the slope; the turnover assembly adjacent to the higher end of the slope circulates along the distribution direction of the feeding position, the heating position and the slope feeding position, and is connected to a feeding device to obtain the drill rods output by the feeding device one by one, and rotate the drill rods until the axis line coincides with the axis line of the heating hole of the heating machine, and transport the drill rods to the higher end of the slope after heating; the turnover assembly adjacent to the lower end of the slope The rotating assembly circulates along the distribution direction of the slope discharge position, upsetting position and blanking position, and is connected to a collecting device to receive the drill rods rolling down the slope one by one, and rotate them until the axis line coincides with the axis line of the upsetting hole of the upsetting machine, and transport them to the collecting device after the drill rod is upset; the two circulating assemblies are connected to a driving unit that drives the two to rotate at the same speed; a transmission device is also provided on the frame, which is used to drive the drill rod on the circulating assembly under the heating position and the drill rod on the circulating assembly under the upsetting position to move back and forth along the axial direction respectively, so that their ends enter and exit the heating machine and the upsetting machine respectively.

[0008] When the drill rod heating and upsetting turnover device of the above technical solution is in operation, the feed device provides the drill rod, and the driving unit drives the two turnover assemblies to operate simultaneously. The turnover assembly adjacent to the slope rotates to the feeding position, obtains the drill rod output by the feeding device, and rotates to the heating position. The transmission device drives the drill rod to move forward, so that the end of the drill rod is inserted into the heating machine for heating treatment, and then the transmission device drives the drill rod to move backward, so that the heated end of the drill rod is separated from the heating machine, and then the driving unit drives the above turnover assembly to rotate to the slope feeding position, so that The drill rod can roll along the slope, while another turnover assembly rotates to the slope discharge position, so that the drill rod rolling down the slope falls on the turnover assembly, and the turnover assembly rotates to the upsetting position, so that the axis of the drill rod is consistent with the axis of the upsetting hole of the upsetting machine, and then the transmission device drives the drill rod to be inserted into the upsetting hole of the upsetting machine, and the upsetting machine performs upsetting on the heated end of the drill rod, and then the transmission device drives the drill rod to retreat, and the drive unit drives the turnover assembly to rotate, so that the drill rod after upsetting is transported to the collection device through the turnover assembly. When the above-mentioned turnover is used, there is no need to manually transport and move the drill rod, which realizes automated turnover processing, reduces labor costs, improves the efficiency of drill rod upsetting, and at the same time reduces labor costs and avoids safety accidents during the upsetting process.

[0009] Preferably, the two circulating components each include a rotating shaft rotating around its own axis and connected to the driving unit, and a clamping unit arranged on the rotating shaft, the clamping unit includes two clamping members distributed along the circumference of the rotating shaft, the rotating shaft and the two clamping members enclose two clamping grooves for placing the drill rod and arranged back to back; when the circulating component adjacent to the higher end of the slope passes through the feeding position, the heating position and the slope feeding position in sequence, the other circulating component passes through the slope discharging position, the upsetting position and the blanking position in sequence.

[0010] By adopting the above technical scheme, the driving unit drives the two clamping members to rotate through the rotating shaft, thereby realizing the change of the rotation position of the turnover assembly, and the drill rod and the two clamping members are enclosed to form two back-to-back clamping grooves, which facilitate the placement of the drill rod on the turnover assembly through the clamping grooves; and when the turnover assembly adjacent to the higher end of the slope passes through the feeding position, the heating position and the slope feeding position in sequence, the other turnover assembly passes through the slope discharging position, the upsetting position and the blanking position in sequence, thereby realizing the synchronous operation of the two turnover assemblies, and facilitating the transmission device to move the drill rods on the two turnover assemblies at the same time, so as to insert the two drill rods into the heating machine and the upsetting machine respectively, or to extract them from the heating machine and the upsetting machine, thereby improving work efficiency.

[0011] Preferably, the driving unit includes a driving motor arranged on the frame and two synchronous wheels which are connected by a synchronous belt drive and are respectively fixedly connected to the rotating shafts of the two rotating components coaxially, and the output end of the driving motor is fixedly connected to the coaxial centerline of one of the synchronous wheels.

[0012] By adopting the above technical solution, a driving motor drives one of the synchronous wheels to rotate, and the synchronous wheel is connected to the other synchronous wheel through a synchronous belt, so that the two synchronous wheels can rotate at the same speed and in the same direction at the same time, thereby driving the two drill rods to rotate at the same speed and in the same direction at the same time, so as to realize the synchronous rotation of the two turnover components.

[0013] Preferably, the feeding device includes a pallet, a side baffle is fixed on the pallet, an outlet for a single drill rod at the bottom to roll through is arranged between the side baffle and the pallet, a push rack is arranged on the side of the side baffle facing away from the two turnover assemblies, the push rack, the side baffle and the pallet together form a storage space for stacking drill rods, and the push rack is connected to a translation unit for adjusting the distance between it and the side baffle.

[0014] By adopting the above technical solution, a storage space is formed by the push frame, the side baffle frame and the pallet for stacking drill rods. An outlet is provided between the side baffle frame and the pallet for a single drill rod at the bottom to roll through. During operation, the push frame is pushed toward the side baffle frame by the translation unit, so that the stacked drill rods roll out one by one from the bottom outlet, making it convenient for the turnover assembly adjacent to the higher end of the slope to obtain it.

[0015] Preferably, a pushing unit is provided on the pushing frame to cooperate with the translation unit to push the drill rods stacked in the storage space one by one through the gap between the side stop frame and the support plate and move to the turnover assembly adjacent to the higher end of the slope.

[0016] By adopting the above technical solution, the pushing unit is operated to act on the bottom layer of drill rods stacked in the storage space, so that after the bottom layer of drill rods is thrust, it moves toward the gap between the side frame and the support plate, so that the drill rods can pass through the gap between the side frame and the support plate one by one, making it convenient for the turnover assembly adjacent to the higher end of the slope to obtain the drill rods moved out of the gap.

[0017] Preferably, the transmission device includes two transmission components, which correspond to two circulating components one by one respectively; the two transmission components each include a transmission unit, the transmission unit includes a roller rotating around its own axis, a power unit driving the roller to rotate and a lifting unit connected to the power unit, the lifting unit is connected to the frame, the axis of the roller is perpendicular to the axis of the drill rod on the circulating component in the heating position and the axis of the drill rod on the circulating component in the upsetting position, and the roller drives the drill rod to move along its axial direction when it rotates.

[0018] By adopting the above technical scheme, the two transmission components respectively control the movement of the drill rods on the two circulating components, thereby improving the movement efficiency of the drill rods and further improving the production efficiency of the drill rods. When it is necessary to control the movement of the drill rods on the circulating components, the lifting unit drives the power unit to move downward, so that the wheel surface of the roller abuts against the circumferential outer edge of the drill rod, and then the rotating unit drives the roller to rotate, and the drill rod is driven to move along its axial direction through friction. According to the rotation direction of the roller, the movement direction of the drill rod is controlled, so that the drill rod can be extended into or moved out of the heating machine and the upsetting machine, which is convenient for heating and upsetting treatment; when the circulating component needs to be rotated to adjust its position, the lifting unit drives the power unit to move upward, so that the roller is separated from the drill rod, which is convenient for the rotation of the circulating component.

[0019] Preferably, the transmission unit is provided with two rollers, which are spaced apart along the axial direction of the rollers.

[0020] By adopting the above technical solution, the number and area of ​​force contact points between the drill rod and the roller are increased when the drill rod moves, so as to increase the friction between the drill rod and the roller, so that when the roller rotates, it can drive the drill rod to move along its axial direction.

[0021] Preferably, an elastic wear-resistant ring is provided on the circumferential outer edge of the roller.

[0022] By adopting the above technical solution, when the drill rod is driven to move, the wear-resistant ring undergoes elastic deformation, thereby increasing the contact area and contact pressure with the drill rod, and at the same time increasing the friction between the drill rod and the wear-resistant ring, so that when the rotating unit drives the wear-resistant ring to rotate through the roller, it can ensure that the drill rod rotates along its axial direction, and the wear-resistant ring protects the roller to prevent the rigid roller from contacting the rigid drill rod, which causes the roller to be damaged when relative friction occurs between the roller and the drill rod.

[0023] Preferably, the power unit and the lifting unit are connected via an elastic member, and a slidably matched directional rod and directional hole are provided between the two.

[0024] By adopting the above technical solution, the elastic member is used to facilitate the adjustment of the distance between the power unit and the lifting unit. At the same time, the elastic member is used to apply pressure to the rotating unit to adjust the pressure between the roller and the drill rod, thereby adjusting the friction force on the drill rod when the roller rotates, which facilitates the stable rotation of the drill rod. In addition, the sliding-fitting directional rod and directional hole are used to ensure that when the lifting unit is in operation, the power unit only moves stably in the vertical direction.

[0025] Preferably, a guide member is provided on the side of the turnover assembly adjacent to the lower end of the slope facing away from the slope, and the side wall of the guide member adjacent to the turnover assembly is an arc-shaped wall. The arc-shaped wall is arranged directly above the collecting device and is enclosed with the turnover assembly to form a guide channel for the drill rod to roll into the collecting device.

[0026] By adopting the above technical solution, the drill rod rolling down from the turnover assembly is changed by utilizing the arc wall of the guide member. After the drill rod rolls along the arc wall, it falls into the collecting device. This helps to save the horizontal space occupied by the device and facilitates the activities of workers.

[0027] To sum up, compared with the prior art, the drill rod heating and upsetting turnover device of the present invention drives two turnover components to operate simultaneously through a driving unit. After obtaining the drill rod provided by the feeding device, the drill rod is moved in cooperation with the transmission device so that the drill rod can be heated and upset in turn, reducing the workload of workers and labor costs, while improving the drill rod processing efficiency and avoiding safety accidents during the process of workers carrying and moving the drill rod.

DETAILED DESCRIPTION

[0045] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0046] Example 1

[0047] like Figure 1-Figure 10 As shown, the drill rod heating and upsetting turnover device of Example 1 is mainly used to cooperate with the heating machine 800 and the upsetting machine 900. After the part of the drill rod 500 to be processed is inserted into the heating hole 801 of the heating machine 800 for heating, the drill rod 500 is pulled out, and then the heated part of the drill rod 500 is inserted into the upsetting machine 900 for upsetting, and then the drill rod 500 is pulled out and the upsetting completed drill rods 500 are stacked together.

[0048] The drill rod heating and upsetting turnover device of this embodiment includes a frame 100 , which includes four supporting legs 101 distributed on the ground in four rectangular arrays and three L-shaped side brackets 102 distributed side by side on the same side of the supporting legs 101 .

[0049] The frame 100 is provided with a feeding device 400, which includes a horizontal support plate 401, on which a side block frame 402 is fixed, and the side block frame 402 is arranged in a vertical direction, and its length direction is consistent with the length direction of the three side brackets 102, and there is an outlet between the side block frame 402 and the support plate 401 for a single drill rod 500 to roll through, and the top of the side block frame 402 is fixedly connected to one end of the three side brackets 102 away from the ground, and the two ends of the side block frame 402 are fixedly connected to the end block frames 403, and the end block frames 403, the side block frames 402 and the support plate 401 are vertically connected to each other. Fixed connection; a push frame 404 is provided on one side of the side baffle frame 402, which is consistent with its length direction and extends in the vertical direction. The bottom edge of the push frame 404 is in contact with the support plate 401, so that the push frame 404, the baffle frame and the support plate 401 enclose a storage space for stacking drill rods 500. The push frame 404 is connected to a translation unit 405 to adjust the distance between the push frame 404 and the side baffle frame 402. The translation unit 405 is a translation cylinder, and three of them are provided and spaced apart along the length direction of the side baffle frame 402. The cylinder body of the translation cylinder is fixed on the support plate 401, and the piston rod is fixedly connected to the push frame 404.

[0050] The supporting surface of the pallet 401 is also fixed with a ramp 200. Three ramps 200 are provided, all of which are provided on the side of the side frame 402 away from the push frame 404 and are spaced apart along the length direction of the side frame 402. The higher end of the ramp 200 is provided between the lower end and the side frame 402, and both the higher end and the lower end are provided with a turnover assembly 300. The two turnover assemblies 300 are connected to a driving unit 700 that drives the two to rotate at the same speed; the frame 100 is also provided with a transmission device, and a collection device 600 is provided on one side of the turnover assembly 300 adjacent to the lower end of the ramp 200, and the collection device 600 is a collection box with an open top.

[0051] The turnover assembly 300 adjacent to the higher end of the slope 200 is closely arranged between the side frame 402 and the slope 200, and the turnover assembly 300 circulates along the distribution direction of the feeding position, the heating position and the feeding position of the slope 200; when the turnover assembly 300 rotates to the feeding position, the turnover assembly 300 obtains a single drill rod 500 rolled out from between the pallet 401 of the feeding device 400 and the side frame 402, and then rotates to the heating position. At this time, the drill rod 500 obtained by the turnover assembly 300 has its axis line coincident with the axis line of the heating hole 801 of the heating machine 800. At this time, the driving unit 700 stops running, the transmission device starts, and the drilling rod 500 is driven. The rod 500 moves along its axial direction so that its end to be processed extends into the heating hole 801 of the heating machine 800. After the heating machine 800 heats the end of the drill rod 500, the transmission device is started again to drive the drill rod 500 to move along its axial direction so that the heated end is separated from the heating machine 800, and then the driving unit 700 drives the above-mentioned turnover assembly 300 to rotate to the feeding position of the slope 200. At the storage position of the slope 200, the heated drill rod rolls down along the slope 200, and then the driving unit 700 drives the turnover assembly 300 to continue to rotate, and circulates along the distribution direction of the feeding position, the heating position and the feeding position of the slope 200.

[0052] The driving unit 700 drives the rotating assembly 300 adjacent to the higher end of the slope 200 to rotate, while the rotating assembly 300 adjacent to the lower end of the slope 200 rotates synchronously, and the rotating assembly 300 rotates cyclically along the distribution directions of the oblique discharge position, the upsetting position and the blanking position; specifically, after the rotating assembly 300 rotates to the storage position of the slope 200, the rotating assembly 300 receives the drill rod 500 rolling down from the slope 200, and then rotates to the upsetting position, driving the drill rod 500 to rotate synchronously, at which time the axis of the drill rod 500 is aligned with the upsetting hole of the upsetting machine 900 901 axis lines coincide, the driving unit 700 stops running, the corresponding transmission device starts, and drives the drill rod 500 to move along its axial direction, so that the heated end of the drill rod 500 extends into the upsetting hole 901 of the upsetting machine 900. After the upsetting machine 900 performs upsetting treatment on the heated end, the transmission device starts, drives the drill rod 500 to move along its axial direction, so that the drill rod 500 is separated from the upsetting machine 900, and then the driving unit 700 continues to run, driving the above-mentioned turnover assembly 300 to rotate to the blanking position, so that the upsetting completed drill rod 500 enters the collecting device 600. The driving unit 700 continues to run, driving the turnover assembly 300 adjacent to the lower end of the slope 200 to perform cyclic rotation along the distribution direction of the material position, the upsetting position and the blanking position.

[0053] like Figure 8 and Fig. 9As shown, the two rotating assemblies 300 each include a rotating shaft 301 disposed on a support plate 401, the axial direction of the rotating shaft 301 is consistent with the length direction of the side stop frame 402, and the rotating shaft 301 is arranged to rotate around its own axis, and the rotating shaft 301 is provided with three clamping units distributed along its axial direction, and the three clamping units each include two clamping pieces 302 distributed along the axial direction of the rotating shaft 301, and the rotating shaft 301 and the two clamping pieces 302 are enclosed to form two clamping grooves arranged back to back, and the clamping grooves are used to store the drill rod 500. Two limiting rings 140 are also sleeved on the outside of the rotating shaft 301, and the two limiting rings 140 are fixedly connected to the support plate 401, and the circumferential inner walls thereof are in contact with the circumferential outer edges of the rotating shaft 301, and the three clamping units are clamped between the two limiting rings 140, that is, the limiting rings 140 are in contact with the clamping pieces 302 of the end clamping units, so as to ensure that the rotating shaft 301 rotates stably around its own axis.

[0054] In order to drive the rotating shafts 301 in the two rotating components 300 to rotate in the same direction and at the same speed, the driving unit 700 includes a driving motor 701, a synchronous belt 702 and two synchronous wheels 703 with the same outer diameter. The driving motor 701 is fixed on the support plate 401, and the output end of the driving motor 701 is fixedly connected to one of the synchronous wheels 703. The two synchronous wheels 703 are respectively fixedly connected to the rotating shafts 301 in the two rotating components 300 coaxially, and the two synchronous wheels 703 are driven and connected by the synchronous belt 702.

[0055] When it is necessary to drive the two rotating assemblies 300 to move, the driving motor 701 in the driving unit 700 is started, driving one of the synchronous wheels 703 to rotate, and the synchronous wheel 703 drives the other synchronous wheel 703 to rotate through the synchronous belt 702, so that the two rotating shafts 301 rotate at the same speed in the same direction at the same time, thereby changing the position of the clamping groove on the rotating assembly 300.

[0056] A guide member 130 is provided on the side of the turnover assembly 300 adjacent to the lower end of the slope 200 facing away from the slope 200. There are three guide members 130 in total, which are spaced apart along the length direction of the side frame 402. The side wall adjacent to the guide member 130 and the turnover assembly 300 is an arcuate wall 131. The arcuate wall 131 is provided directly above the collecting device 600 and is enclosed with the above-mentioned turnover assembly 300 to form a guide channel for the drill rod 500 to roll into the collecting device 600.

[0057] Specifically, Figure 7 As shown, one of the clamping grooves of the turnover assembly 300 adjacent to the higher end of the slope 200 (hereinafter referred to as the "higher position turnover assembly 300") is rotated to be directly opposite to and close to the gap between the side baffle 402 and the support plate 401 of the feeding device 400, so that the drill rod 500 rolled out of the above gap enters the clamping groove, as shown in FIG. Figure 7 As shown in (a), at this time, the rotating assembly 300 at the higher position rotates to the feeding position;

[0058] The driving unit 700 continues to operate, and the upper position of the turnover assembly 300 rotates to the heating position, such as Figure 7 As shown in (b), at this time, the two clamping grooves on the turnover component 300 are facing upward and downward respectively, and the groove walls of the two clamping grooves are at an angle of 45° with the horizontal plane, and the axis of the drill rod 500 on the turnover component 300 is consistent with the axis of the heating hole 801 of the heating machine 800. At this time, the transmission component drives the drill rod 500 to move along its axial direction, so that the end of the drill rod 500 to be processed is inserted into the heating machine 800, and the heating machine 800 heats the end of the drill rod 500, and then the transmission device extracts the heated drill rod 500 and separates it from the heating machine 800;

[0059] Afterwards, the driving unit 700 continues to operate, driving the higher position of the turnover assembly 300 to rotate to the ramp 200 feeding position, such as Figure 7 As shown in (c), at this time, one side wall of the two side walls of the clamping groove containing the drill rod 500 is located above the side of the slope 200, and the other side wall is located in the same plane as the bearing surface of the slope 200, so that the drill rod 500 rolls down the slope 200 along the side wall, and then rolls down along the slope 200. The other clamping groove is directly opposite to and close to the gap between the support plate 401 and the side frame 402 in the feeding device 400. Among the drill rods 500 stacked in the feeding device 400, the bottom drill rod 500 is The drill rod 500 rolls into the clamping groove through the gap, and at the same time, the turnover assembly 300 adjacent to the lower end of the ramp 200 (hereinafter referred to as the "lower position turnover assembly 300") rotates to the material storage position of the ramp 200. One of the two side walls of one of the two clamping grooves on the turnover assembly 300 is located in the same plane as the load-bearing surface of the ramp 200, and the other side wall is located above the side of the above side wall, so that the drill rod 500 rolling down from the ramp 200 rolls into the clamping groove of the lower position turnover assembly 300;

[0060] Then, the driving unit 700 continues to operate, driving the upper rotating assembly 300 to rotate to the heating position, and the lower rotating assembly 300 to rotate to the upsetting position, such as Figure 7As shown in (d), the axis center line of the drill rod 500 on the lower position turnover assembly 300 is consistent with the axis center line of the upsetting hole 901 of the upsetting machine 900. At the same time, the upper position turnover assembly 300 rotates to the heating position, and the axis center line of the drill rod 500 in the upper clamping groove is consistent with the axis center line of the heating hole 801 of the heating machine 800. The driving unit 700 stops running, and the corresponding transmission device is started to move the drill rods 500 on the two turnover assemblies 300 along the axial direction, so that the two drill rods 500 are respectively inserted into the heating machine 800 and the upsetting machine 900 at the same time. The heating machine 800 and the upsetting machine 900 heat and upset the unprocessed drill rod 500 and the heated drill rod 500 respectively. After that, the transmission device is operated to move the drill rod 500 just heated and the drill rod 500 just upset along their respective axial directions, and respectively separate from the heating machine 800 and the upsetting machine 900;

[0061] After the two drill rods 500 are processed, the driving unit 700 continues to operate. Figure 7 As shown in (e), the higher position of the turnover assembly 300 rotates to the feeding position of the slope 200, and the lower position of the turnover assembly 300 rotates to the discharging position of the slope 200. The drill rod 500 that has just been heated rolls down along the side wall of the higher position of the turnover assembly 300, passes through the slope 200 and falls into one of the clamping grooves of the lower position of the turnover assembly 300. In addition, another clamping groove of the higher position of the turnover assembly 300 is opposite to the gap between the side guard 402 and the support plate 401, which is convenient for obtaining the drill rod 500 at the bottom of the feeding position, and the drill rod 500 that has been upsetting enters the guide channel formed by the lower position of the turnover assembly 300 and the arc wall 131.

[0062] Afterwards, the drive unit 700 continues to operate, such as Figure 7 As shown in (a), the lower position of the rotating assembly 300 rotates to the blanking position, and during the rotation process, the drill rod 500 that has been upset is rolled into the collecting device 600, and the axis of the drill rod 500 in the guide channel is consistent with the axis of the upset hole 901 of the upset machine 900, while the higher position of the rotating assembly 300 rotates to the heating position, and the axis of the drill rod 500 on its clamping groove is consistent with the axis of the heating hole 801 of the heating machine 800. In this way, the two rotating assemblies 300 are driven by the driving unit 700 to circulate at the same time, that is, when the higher position of the rotating assembly 300 is rotated in a circular manner along the distribution direction of the feeding position, the heating position and the feeding position of the slope 200, the rotating assembly 300 at the bottom position is rotated in a circular manner along the distribution direction of the discharge position, the upset position and the blanking position of the slope 200.

[0063] like Figure 4 , Fig. 9 and Fig.10As shown, the transmission device includes two transmission components, and the two transmission components are arranged one by one directly above the two turnover components 300, and both include a transmission unit 120; the transmission unit 120 includes a lifting unit 123 arranged on the side bracket 102, and the lifting unit 123 is an electric push rod, and its shell is fixedly connected to the side bracket 102, and the push rod extends in the vertical direction, and its bottom end is fixedly connected to a horizontal long strip oriented plate 125, and the length direction of the oriented plate 125 is parallel to the length direction of the side frame 402, and both ends of the oriented plate 125 are provided with through-hole-shaped oriented holes 1251, and the inner side of the oriented hole 1251 is provided with an oriented rod 124 that slides with the oriented plate 125, and the oriented rod 124 is penetrated into the oriented plate 125. In the hole 1251, a limiting convex cover 110 is fixed at the top, and a power unit 122 is arranged at the bottom. The power unit 122 is a rotating motor fixed to the bottom end of the directional rod 124. The output end of the rotating motor is coaxially fixedly connected with two rollers 121 arranged at intervals to drive the two rollers 121 to rotate around the overlapping axis. The two rollers 121 have the same size. The axis of the roller 121 extends in the horizontal direction and is perpendicular to the axis of the drill rod 500 on the rotating assembly 300 in the heating position and the axis of the drill rod 500 on the rotating assembly 300 in the upsetting position. The rotating motor and the directional plate 125 are connected by an elastic member 126, and the elastic member 126 is a spring sleeved on the outside of the directional rod 124.

[0064] When it is necessary to drive the drill rod 500 on the turnover assembly 300 to move along its axial direction, the lifting unit 123 drives the directional plate 125 and the power unit 122 and roller 121 thereunder to move downward, so that the circumferential outer edges of the two rollers 121 are respectively fitted with the circumferential outer edges of the drill rod 500, and the lifting unit 123 continues to operate, the height positions of the power unit 122 and the roller 121 remain unchanged, while the height position of the directional plate 125 decreases, so that the length of the elastic member 126 changes, and the elastic deformation degree of the elastic member 126 can be adjusted, thereby adjusting the contact pressure between the roller 121 and the drill rod 500 and the friction between the roller 121 and the drill rod 500 when the roller 121 rotates. The power unit 122 drives the roller 121 to rotate, and drives the drill rod 500 to move along its axial direction through friction. When the rotation direction of the roller 121 changes, the movement direction of the drill rod 500 can be changed, thereby controlling the drill rod 500 to move forward and backward, so that the drill rod 500 enters and exits the heating machine 800 and the upsetting machine 900, which facilitates the heating machine 800 and the upsetting machine 900 to perform heating and upsetting treatment on the drill rod 500. The output end of the power unit 122 is fixedly connected to the two rollers 121 along the axis, thereby increasing the contact area with the drill rod 500, ensuring that the drill rod 500 can be driven to move along its axial direction during the rotation of the drill rod 500.

[0065] Example 2

[0066] like Figure 11-13As shown, the drill rod heating and upsetting turnover device of Example 2 is based on Example 1, with the difference that a pushing unit 406 is provided on the pushing frame 404 to cooperate with the translation unit 405 to push the drill rods 500 stacked in the storage space one by one through the gap between the side stop frame 402 and the support plate 401 and move to the turnover assembly 300 adjacent to the higher end of the ramp 200.

[0067] Specifically, the pushing unit 406 includes two pushing cylinders, which are spaced apart from the translation cylinder along the length direction parallel to the side block frame 402. The cylinder body of the pushing cylinder is fixed to the bottom of the push frame 404 on the side opposite to the side block frame 402, and its length direction is parallel to the distribution direction of the side block frame 402 and the push frame 404. The piston rod is directed toward the side block frame 402, and the translation unit 405 is started, so that the push frame 404 abuts against the drill rod away from the turnover assembly 300, and then the two pushing cylinders are operated. If the piston rod is directed toward the side block frame 40 2, the drill rods 500 stacked at the bottom of the storage space are pushed, so that the drill rods at the bottom of the storage space close to the side baffle 402 are moved to the turnover assembly 300 adjacent to the higher end of the slope 200 through the gap between the side baffle 402 and the support plate 401; if the piston rod of the pushing cylinder is retracted and moved away from the side baffle 402, the drill rods 500 at a high position in the storage space are moved downward to the support plate 401, and the drill rods 500 are stacked again between the pushing frame 404 and the side baffle 402.

[0068] Example 3

[0069] like Fig.14 As shown, the drill rod heating and upsetting turnover device of Example 3 is based on Example 2, with the difference that an elastic wear-resistant ring 127 is provided on the circumferential outer edge of the roller 121, and the wear-resistant ring 127 is a rubber ring.

[0070] In this embodiment, when the transmission unit 120 is used to drive the drill rod 500 to move along its axial direction, the lifting unit 123 drives the power unit 122 to descend, so that the wear-resistant ring 127 abuts against the circumferential outer edge of the drill rod 500, and the wear-resistant ring 127 is compressed between the drill rod 500 and the roller 121, and elastic deformation occurs, thereby increasing the pressure on the drill rod 500, and then increasing the friction force on the drill rod 500 after the roller 121 rotates, so as to ensure that the drill rod 500 can be displaced along its axial direction. In addition, after the wear-resistant ring 127 is fixed to the circumferential outer edge of the roller 121, it can protect the roller 121 and prevent the rigid roller 121 from directly contacting the drill rod 500, resulting in relative displacement and wear between the roller 121 and the drill rod 500 after the roller 121 rotates. Of course, as a replacement with similar effects, the wear-resistant ring 127 can also be other elastic rings, such as a silicone ring.

[0071] Example 4

[0072] like Fig.15 and Fig.16As shown, the drill rod heating and upsetting turnover device of Example 4 is based on Example 3, with the difference that an arc-shaped clamping piece 303 is fixed on one of the side walls of the clamping piece 302, and the distribution direction of the clamping piece 302 and the clamping piece 303 is consistent with the rotation direction of the two; the side wall of the clamping piece 303 facing away from the clamping piece 302 is an arc-shaped clamping wall, and its radius is half of the outer diameter of the drill rod 500. When the drill rod 500 is located in the clamping groove, the arc-shaped clamping wall of the clamping piece 303 fits against the circumferential outer edge of the drill rod 500.

[0073] In this embodiment, by means of the clip 303 fixed on the side wall of the clamping member 302, when the higher-positioned turnover assembly 300 rotates to the feeding position, the drill rod 500 at the bottom of the feeding device 400 adjacent to the turnover assembly 300 rolls out from the gap between the side baffle 402 and the support plate 401, enters the clamping groove of the turnover assembly 300, and fully contacts the clip 303, thereby increasing the contact area between the turnover assembly 300 and the drill rod 500, and facilitating the synchronous rotation of the drill rod 500 when the rotating shaft 301, the clamping member 302 and the clip 303 rotate.

[0074] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
