[0002] When making a high-pressure tank body, it is generally necessary to forge a high-temperature billet into a predetermined shape, perform hot stretching, and then perform subsequent processing. The high-pressure tank needs to withstand a large pressure, so after it is formed, it needs to be heat treated, such as annealing or normalizing. Conventional annealing or normalizing methods are to take it out of the heating furnace directly and send it directly to the conveyor line for air cooling. The conveyor line generally uses multiple drive rollers, and the end of the drive roller 101 is a conical structure. The pipe fittings are arranged perpendicular to the drive rollers. The high-temperature pipe fittings 102 are conveyed by the rotation of the drive rollers, and heat is dissipated during the conveying process. See Figure 1 However, in this way, the heat dissipation effect of the contact surface between the pipe and the transmission roller is not good, resulting in low heat dissipation efficiency of the pipe, which will increase the length of the conveyor line, occupy more space, and be more expensive.

[0029] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0030] Example 1: See Figure 2 , 3 As shown, a high-temperature pipe conveying and heat dissipation device comprises a frame 1, a plurality of driving rollers 2 rotatably mounted on the frame 1, and a heat dissipation fan 3 arranged directly above the plurality of driving rollers 2;

[0031] The plurality of transmission rollers 2 are arranged at intervals from left to right, and a support spacing 4 is formed between adjacent transmission rollers 2;

[0032] The frame 1 is provided with a driving mechanism for driving the plurality of transmission rollers 2 to rotate simultaneously;

[0033] A lifting pusher 5 is provided at both ends below each of the support intervals 4, and a pushing slope 6 is provided on the top of the lifting pusher 5 and is inclined downward from left to right;

[0034] A lifting mechanism is also provided for driving the plurality of lifting pushers 5 to rise and fall simultaneously;

[0035] When the lifting pusher 5 rises, the pushing inclined surface 6 is arranged above the top surface of the driving roller 2 , and when the lifting pusher 5 descends, the lifting pusher 5 is arranged below the middle part of the driving roller 2 .

[0036] In this embodiment, when actually used, the high-temperature pipe 7 is fed from the left into the leftmost support spacing, and the pipe is supported by the adjacent transmission rollers. Since the driving mechanism drives all the transmission rollers to rotate in the same direction, the support rollers will be used to drive the pipe to rotate in the support spacing, and the presence of the cooling fan will accelerate the flow of air at the pipe, thereby accelerating the heat dissipation efficiency and heat dissipation effect of the pipe, and can also dissipate heat 360 degrees for the pipe. Since a high-temperature pipe is transported to the right at regular intervals on the left, when the next pipe is transported to the right, the lifting mechanism will push the lifting pusher to rise. In this process, the push slopes on both sides will contact the bottom sides of the pipe and lift it up. Since the push slopes are set downward from left to right, in the process of lifting the pipe out of the support spacing, the pipe will also roll to the right and roll into the adjacent right support spacing. In this way, the pipe fittings on the left can enter the support spacing of the adjacent right side, so that multiple pipe fittings can be accommodated on the same rack for heat dissipation at the same time, thereby achieving heat treatment such as annealing or normalizing. Of course, it is also possible to simply achieve accelerated heat dissipation of the pipe fittings. In this way, the space occupancy is small, the cost will be lower, the heat dissipation efficiency will be higher, and the energy consumption will be low. In addition, due to the small space occupancy, the high temperature in the heat treatment workshop will be mainly concentrated at the rack, which is better for the comfort and experience of the staff in other positions of the workshop. The wind speed of the cooling fan can also be adjusted to adjust the heat dissipation efficiency, according to the heat treatment process used, and can also be adjusted according to the number of pipe fittings required to be processed per unit time. The number of drive rollers, cooling fans and jacking pushers can also be adjusted to adjust the number of heat dissipation of pipe fittings that can be processed per unit time, so as to reduce the space occupancy as much as possible.

[0037] See also Figure 2 As shown, there are multiple cooling fans, and the multiple cooling fans are arranged in sequence from left to right directly above the multiple driving rollers.

[0038] In this embodiment, according to the arrangement of the transmission rollers from left to right, the cooling fans are arranged from left to right, so that when the transmission rollers rotate and support and convey the products within the support interval, the cooling fans above can be used to accelerate the heat dissipation of the pipes. Of course, the cooling fans at the corresponding positions can be turned on or off according to the required heat dissipation speed, or the speed of the fans can be adjusted to adjust the heat dissipation speed.

[0039] See also Figure 2 , 3 As shown, the driving roller 2 includes a coupling 8 and a hollow structured sleeve 9, wherein both ends of the coupling 8 are rotatably connected to the frame 1, and the sleeve 9 is coaxially arranged on the outside of the coupling 8, and a plurality of reinforcing connecting strips 10 are arranged on the outer surface of the coupling 8, and the reinforcing connecting strips 10 are connected to the inner wall of the sleeve 9, wherein the inner diameter of the sleeve is larger than the outer diameter of the coupling.

[0040] In this embodiment, since the pipe is a high-temperature pipe with a high temperature, a transmission roller is used to support the high-temperature pipe. The outer surface of the high-temperature pipe will directly contact the outer surface of the transmission roller. If a transmission roller with a solid structure is directly used, the heat dissipation effect is poor after the high temperature is transferred to the transmission roller, and the high temperature of the transmission roller will also affect the heat dissipation of the pipe. Therefore, the transmission roller is rotatably connected with the frame by a coupling, and the sleeve is connected with the coupling through multiple reinforcing connecting strips. In this way, the sleeve adopts a hollow structure to support the pipe, which can also improve the heat dissipation efficiency of the transmission roller itself, and air can also flow through both ends of the sleeve, further increasing the heat dissipation effect, which can not affect the normal heat dissipation of the pipe. At the same time, it can also extend the service life of the transmission roller and reduce its maintenance rate. The provision of multiple reinforcing connecting strips also plays a role in increasing the strength of the sleeve.

[0041] Furthermore, a plurality of heat dissipation holes 11 communicating with the inner wall of the sleeve 9 are provided on the outer surface of the sleeve 9. The presence of the heat dissipation holes can further increase the contact area between the sleeve and the air, and at the same time increase the flow exchange between the air inside the sleeve and the air outside the sleeve, thereby improving the heat dissipation effect, and can also increase the heat dissipation effect of the pipe during the rotational contact between the pipe and the sleeve.

[0042] In the utility model, the lifting and pushing member has two layout modes:

[0043] The first one: see Figure 2 , 3 As shown, the lifting and pushing member is arranged below between two adjacent sleeves.

[0044] In this way, when the jacking pusher moves upward, it can move upward from the support distance, push the bottom of the pipe fitting upward, and roll rightward through the push inclined surface into the support distance on the right side.

[0045] The second type: the lifting and pushing member is arranged outside the end of the sleeve, and the lifting and pushing member is arranged between two adjacent connecting shafts.

[0046] Among them, in the second mode, the two sides of the middle outer surface of the pipe fitting are respectively against the outer surfaces of the two adjacent sleeves, and the two ends of the pipe fitting will be outside the two ends of the sleeve. Therefore, the lifting pusher is between the two adjacent couplings and outside the ends of the sleeve, that is, the front lifting pusher is beside the front end of the sleeve, and the rear lifting pusher is beside the rear end of the sleeve, which does not affect the normal rotation of the sleeve and the coupling. When the lifting pusher moves down, the top of the lifting pusher will be below the bottom outer surface of the pipe fitting, which does not affect the normal rotation of the pipe fitting. When the lifting pusher moves up, the top surface of the lifting pusher will contact the end of the pipe fitting, and the lifting pushers on both sides will move upward to lift the lifting pusher. Due to the existence of the pushing inclined surface, during the process of the pipe fitting being lifted, the pipe fitting rolls to the right along the pushing inclined surface by its own weight to the transmission roller on the right side, and rolls to the support spacing on the right side, thereby realizing the rightward transportation of the pipe fitting.

[0047] Both methods can be adopted. The position of the lifting pusher can be selected according to the distance of the support spacing. If the spacing value of the support spacing is greater than the width of the lifting pusher, the first method can be adopted. If the spacing value of the support spacing is less than the width of the lifting pusher, the second method is adopted. In this embodiment, the first method is adopted. Only two groups of lifting pushers are arranged below each support spacing, which can reduce materials, reduce costs, and ensure the stability and quality of lifting.

[0048] See also Figure 2 , 3 As shown, the lifting mechanism includes a lifting hydraulic cylinder 12 and a lifting bracket 13, the lifting bracket 13 is connected to the frame 1 for vertical movement, the bottom of the lifting hydraulic cylinder 12 is installed on the frame 1, the output shaft at the top of the lifting hydraulic cylinder 12 is connected to the lifting bracket 13, and the lifting hydraulic cylinder 12 is configured to drive the lifting bracket 13 to move vertically;

[0049] The bottoms of the plurality of lifting pushers 5 are mounted on the lifting bracket 13 .

[0050] The lifting and pushing member comprises a lifting plate, and the top surface of the lifting plate constitutes the pushing inclined surface.

[0051] In this embodiment, there is at least one group of lifting hydraulic cylinders. The number of pipes that need to be driven simultaneously for lifting can be adjusted according to the weight of the pipes and the number of drive rollers. Preferably, two or four groups of lifting hydraulic cylinders are used, which are evenly distributed under the lifting bracket. In this way, the force on each part of the lifting bracket is more evenly distributed, and the stability of the lifting is also guaranteed.

[0052] During use, no matter how many pipe fittings are arranged in the support spacing, when the pipe fitting needs to be moved to the right by one position, the output shaft of the jacking hydraulic cylinder extends, driving all the jacking pushers to move upward. When all the jacking pushers move upward, the top of the jacking pusher contacts the bottom surface of the end of the pipe fitting in the corresponding support spacing, pushing the pipe fitting upward, so that the pipe fitting disengages from the transmission roller and moves upward, and then the pipe fitting rolls to the right under the weight, and it will roll to the top surface of the transmission roller at the right end, but will be limited by the left side of the jacking pusher on the right side. At this time, the pipe fitting will be between the right transmission roller and the right jacking pusher, and be arranged close to the right side of the transmission roller on the right side, and then the jacking pusher moves downward. In this process, the pipe fitting moves to the right and enters the support spacing, and the outer surfaces on both sides of the bottom of the pipe fitting abut against the outer surfaces of the transmission rollers on both sides of the support spacing, thereby realizing that all pipe fittings are synchronously moved to the right by one position.

[0053] See also Figure 3 As shown, two axially arranged sprockets 14 are provided at one end of the transmission roller 2, and the driving mechanism includes a motor 15 and a plurality of chains 16. Each of the chains 15 is respectively wound around the sprocket 14 at the end of the adjacent transmission roller 2, and the motor 15 is configured to drive one of the transmission rollers 2 to rotate.

[0054] In this embodiment, the sprocket is arranged on the outer surface of the coupling shaft, and the two sprockets are arranged axially at intervals, wherein the plurality of transmission rollers arranged from left to right, the sprocket is arranged at the front end or the rear end of the transmission roller, and the sprocket is arranged at the rear end of the transmission roller, and the transmission rollers are respectively the first transmission roller, the second transmission roller, the third transmission roller, the fourth transmission roller, etc. from left to right, and the chains are respectively the first chain, the second chain, the third chain, etc. from left to right, for example, the two ends of the first chain are respectively meshed with the sprockets at the front ends of the first transmission roller and the second transmission roller, the two ends of the second chain are respectively meshed with the sprockets at the rear ends of the second transmission roller and the third transmission roller, and the two ends of the third chain are respectively meshed with the sprockets at the front ends of the third transmission roller and the fourth transmission roller, and so on, and the motor only needs to be connected to the end of one of the transmission rollers, and the chain can drive all the transmission rollers to rotate simultaneously and in the same direction. Among them, the motor drives the coupling shaft of a transmission roller to rotate.

[0055] More preferably, the motor 15 is connected to the end of one of the transmission rollers 2 via a speed reducer 17. In this way, the speed of the transmission roller can be easily adjusted, and the motor can drive the transmission roller to rotate even with a smaller power, thereby reducing costs and size.
