Through the coordination of rotation and welding, the circumferential connection of the first cylinder 21 and the second cylinder 22 is completed, so that the first cylinder 21 and the second cylinder 22 are connected to form at least a part of the cylinder 20.

[0034] When the first cylinder 21 and the second cylinder 22 are connected, the first cylinder 21 is driven to rotate by the driving member 300, so that the welding operation and the rotation of the cylinder 20 can cooperate with each other, so that the welding process can adopt the flat welding process throughout.

[0036] In some embodiments provided in this application, Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, optionally, the cylinder assembly device of the cylindrical mixer also includes: a mounting seat assembly 400, a bracket 500 and a connecting piece 600, the mounting seat assembly 400 includes a first mounting seat 410 and a second mounting seat 420, the first mounting seat 410 is rotatably connected to the roller 100, the second mounting seat 420 is rotatably connected to the supporting roller 200, and the bracket 500 is provided with a long hole 510, the long hole 510 extends along a first direction, and the first direction is perpendicular to the axis of the first cylinder 21, the connecting piece 600 passes through the long hole 510, and the connecting piece 600 is respectively connected to the bracket 500 and the mounting seat assembly 400.

[0037] In this embodiment, the first mounting seat 410 and the second mounting seat 420 are rotatably connected to the roller 100 and the support roller 200 respectively, and the number of the first mounting seat 410 and the second mounting seat 420 is the same as the number of the roller 100 and the support roller 200 respectively.

[0038] The long hole 510 on the bracket 500 extends along the first direction. Figure 1 and Figure 5 In the figure, the direction indicated by the arrow at X is the first direction, which is perpendicular to the axis of the first cylinder 21. The mounting seat assembly 400 is connected to the bracket 500 through the connecting piece 600 in the long hole 510. Specifically, the bracket 500 includes a roller frame 520 and a support roller frame 530, the roller frame 520 is connected to the first mounting seat 410, and the support roller frame 530 is connected to the second mounting seat 420.

[0039] By adjusting the position of the connecting piece 600 in the long hole 510, the position of the mounting seat assembly 400 relative to the bracket 500 can be adjusted, and then the distance between the mounting seat assemblies 400 can be adjusted along the first direction. The supporting position of the roller 100 or the supporting roller 200 on the cylinder 20 is adjusted by the mounting seat assembly 400, so that the supporting position matches the diameter size of the first cylinder 21 or the second cylinder 22, thereby improving the stability of the supporting cylinder 20 and the applicability of the cylinder 20 assembly device, and expanding the scope of use of the cylinder 20 assembly device.

[0040] Illustratively, the connector 600 may be a bolt and a nut.

[0041] In some embodiments provided in this application, Figure 3 and Figure 4 As shown, optionally, the cylinder assembly device of the cylindrical mixer also includes: a support plate 710, an adjusting member 720 and a pad 730, the support plate 710 is connected to the bracket 500, the adjusting member 720 is connected to the support plate 710, the first end of the adjusting member 720 is used to abut against the mounting seat assembly 400, the adjusting member 720 can adjust the length of the first end extending out of the support plate 710 along the first direction, and the pad 730 is used to connect to the bottom of the bracket 500.

[0042] In this embodiment, the support plate 710 is arranged at one side where the bracket 500 is connected to the mounting seat assembly 400. The support plate 710 is provided with a through hole along the first direction, and the first end of the adjusting member 720 can extend out of the through hole. By controlling the length of the first end of the adjusting member 720 extending out of the support plate 710 along the first direction, the first end is abutted against the mounting seat assembly 400, and the adjusting member 720 applies a force to the mounting seat assembly 400. When the connecting member 600 and the bracket 500 are in a state to be connected, the adjusting member 720 can push the mounting seat assembly 400 to move along the first direction, adjust the position of the mounting seat assembly 400, and improve the convenience and accuracy of adjusting the position of the mounting seat assembly 400.

[0043] In a possible embodiment, the adjusting member 720 is a screw rod, and the adjusting member 720 cooperates with a threaded hole on the support plate 710 . The length of the first end extending out of the support plate 710 is controlled by rotating the adjusting member 720 .

[0044] In another possible embodiment, an end plate is provided at the end of the adjusting member 720, and the length of the first end extending out of the support plate 710 is controlled by knocking the end plate.

[0045] The pad 730 is arranged at the bottom of the bracket 500 to adjust the height of the bracket 500, and then adjust the height of the mounting seat assembly 400, and adjust the vertical height of the first cylinder 21 or the second cylinder 22 through the roller 100 or the support roller 200, control the coaxiality of the first cylinder 21 and the second cylinder 22, and improve the accuracy of the connection of the cylinder 20. By adjusting the height of the pad 730 and the spacing of the mounting seat assembly 400, it can adapt to cylinders 20 of different specifications and improve the use efficiency of the cylinder 20 assembly device.

[0046] For example, there are multiple pads 730, which are divided into multiple groups according to thickness, and the pads 730 can be divided into four groups. The top surface of the pad 730 can form an inclined angle with the adjacent side surface to adjust the angle of the bracket 500 and improve the adaptability of the bracket 500 to the installation site.

[0047] In some embodiments provided in this application, Figure 5 As shown, optionally, there are multiple adjusting members 720 , and the multiple adjusting members 720 are divided into multiple adjusting member 720 groups, and the multiple adjusting member 720 groups are arranged at intervals along the axis of the first cylinder 21 .

[0048] In this embodiment, the plurality of adjusting members 720 are divided into a plurality of adjusting member 720 groups, and any one of the adjusting member 720 groups includes at least two adjusting members 720 spaced apart along the first direction, and the two adjusting members 720 are respectively disposed on both sides of the mounting seat assembly 400. The adjusting member 720 groups are spaced apart along the axis of the first cylinder 21, so that the adjusting members 720 are distributed in a square shape on the periphery of the mounting seat assembly 400, and the adjusting members 720 can push the mounting seat assembly 400 in the four corner directions respectively, and then adjust the extension direction of the axis of the first cylinder 21 or the second cylinder 22 through the roller 100 or the support roller 200, control the coaxiality of the first cylinder 21 and the second cylinder 22, and improve the accuracy of the connection of the cylinder 20.

[0049] In some embodiments provided in this application, Figure 6 As shown, optionally, the assembly device of the cylinder 20 further includes a fixing member 800 , and two ends of the fixing member 800 are respectively used to connect the first cylinder 21 and the second cylinder 22 .

[0050] In this embodiment, before welding the cylinder 20, the first cylinder 21 and the second cylinder 22 are first connected by the fixing member 800, the first cylinder 21 and the second cylinder 22 are roughly fixed, and then the cylinder 20 is welded, thereby improving the stability of the cylinder 20 during welding, and improving the welding quality and operating convenience of the cylinder 20.

[0051] Exemplarily, the fixing member 800 may be a channel steel, the length of the fixing member 800 is 80 mm to 100 mm, the number of the fixing members 800 may be multiple, and the multiple fixing members 800 are evenly distributed along the circumference of the cylinder 20 .

[0052] In a second aspect of the present application, an embodiment provides a method for installing a cylinder, such as Figure 8 As shown, the method for installing the drum utilizes the drum assembly device of the drum mixer provided by any one of the first aspect embodiments of the present application, and the method for installing the drum includes:

[0053] Step 102, installing the first cylinder on the roller;

[0054] Step 104, installing the second cylinder on the support roller;

[0055] Step 106, adjusting the coaxiality of the first cylinder and the second cylinder based on the position of the first cylinder;

[0056] Step 108, flat welding is used to weld the outer side and the inner side of the cylinder, and the supporting roller is driven to rotate by a driving member to connect the end of the first cylinder with the end of the second cylinder in a circumferential direction.

[0057] In this embodiment, the cylinder is welded together by a first cylinder and a second cylinder. The first cylinder is first placed on a support roller, and then the second cylinder is placed on a supporting roller. The axial position of the second cylinder is adjusted according to the axial position of the first cylinder, and then the coaxiality of the second cylinder and the first cylinder is adjusted and detected to make the coaxiality reach an acceptable range, thereby completing the preparation work before connecting the first cylinder and the second cylinder.

[0058] The inner and outer sides of the connecting ends of the first cylinder and / or the second cylinder are provided with grooves, and the grooves are welded by flat welding, and the flat welding position is the top or bottom of the cylinder. It should be noted that flat welding refers to a welding process in which the welding position is in a horizontal position or a weld with a small inclination angle, the welding rod is located above the workpiece, and the welder looks down at the workpiece.

[0059] During the welding process, the supporting roller is driven to rotate by the driving member, so that the supporting roller drives the first cylinder to rotate, and the connected first cylinder can drive the second cylinder to follow, thereby controlling the rotation angle of the first cylinder and the second cylinder, so that the welded part of the cylinder is turned away from the welding station, and the position to be welded is turned to the top or bottom of the cylinder, and then the cylinder is continued to be flat welded. Through the coordination of rotation and welding, the circumferential connection of the first cylinder and the second cylinder is completed, so that the first cylinder and the second cylinder are connected to form at least a part of the cylinder.

[0060] When the first cylinder and the second cylinder are connected, the first cylinder is driven to rotate by the driving member, so that the welding operation and the rotation of the cylinder can cooperate with each other, so that the welding process can adopt the flat welding process throughout. Since the welding position of flat welding reduces the welding difficulty, it has the characteristics of high welding accuracy and strength, and fast welding speed, thereby improving the convenience and connection efficiency of the cylinder connection, improving the connection quality of the cylinder, enabling the cylinder to be transported in parts and installed on site, avoiding the traditional overall transportation method, and reducing the installation and transportation costs of the cylinder.

[0061] For example, the number of the second cylinders may be multiple, and after step 108, the process further includes: connecting the first cylinder and the second cylinder to form a new first cylinder, and continuing to perform step 104 until all the cylinders are welded. The number of support rollers may be the same as the number of the second cylinders, and the second cylinders may be mounted on corresponding support rollers, or multiple second cylinders may be sequentially mounted on the same support roller.

[0062] In a possible embodiment, the step of driving the support roller to rotate by the driving member specifically includes: driving the support roller to rotate intermittently by the driving member, and performing flat welding on the first cylinder and the second cylinder when the driving member is in a stopped state.

[0063] In another possible embodiment, the step of driving the support roller to rotate by the driving member specifically includes: driving the support roller to rotate continuously by the driving member, flat welding the first cylinder and the second cylinder, and automatically welding the cylinders by the welding device.

[0064] In some embodiments provided in the present application, optionally, the step of adjusting the coaxiality of the first cylinder and the second cylinder specifically includes: checking the parallelism between the axis of the roller and the axis of the first cylinder; adjusting the number of pads and controlling the extension length of the adjusting member to adjust the position of the second mounting seat; adjusting the coaxiality of the first cylinder and the second cylinder to within a predetermined threshold range.

[0065] In this embodiment, the axis of the roller is checked to make the axis of the roller parallel to the axis of the first cylinder, so that the first cylinder can rotate smoothly on the roller.

[0066] The height of the supporting roller frame is adjusted by adjusting the number of pads, and then the vertical height of the second mounting seat is adjusted. The horizontal position and the axis extension direction of the second mounting seat are adjusted by controlling the extension length of the adjusting member. By performing multi-dimensional adjustment on the second mounting seat, the position of the supporting roller can be accurately adjusted, and then the accurate position of the second cylinder can be adjusted, so that the coaxiality of the first cylinder and the second cylinder is adjusted to within a predetermined threshold range, thereby improving the connection accuracy of the first cylinder and the second cylinder.

[0067] In some embodiments provided in the present application, optionally, after the step of checking the parallelism between the axis of the roller and the axis of the first cylinder, the step further includes: when the checking result is unqualified, adjusting the extension length of the adjusting members of the plurality of adjusting member groups to adjust the extension direction of the axis of the roller; and re-checking the parallelism between the axis of the roller and the axis of the first cylinder.

[0068] In this embodiment, when the parallelism between the axis of the roller and the axis of the first cylinder exceeds a preset threshold, the verification result is unqualified, and the extension lengths of the adjusting members of the multiple adjusting member groups are adjusted so that the adjusting members push the mounting seat assembly in the four corner directions respectively, thereby adjusting the extension direction of the axis of the first cylinder through the roller, controlling the parallelism between the axis of the roller and the axis of the first cylinder, improving the contact between the first cylinder and the roller, improving the smoothness of the rotation of the first cylinder, and thereby improving the accuracy of the cylinder connection.

[0069] After the adjustment is completed, the parallelism of the two axes is re-checked until the parallelism is within the preset threshold range, that is, the verification result is qualified.

[0070] In some embodiments provided in the present application, optionally, before the step of welding the outer side and the inner side of the cylinder by flat welding, the step further includes: connecting the two ends of the fixing member to the first cylinder and the second cylinder respectively.

[0071] In this embodiment, before welding the cylinder, the first cylinder and the second cylinder are first connected by a fixing member, the first cylinder and the second cylinder are roughly fixed, and then the cylinder is welded, which improves the stability of the cylinder during welding, and improves the welding quality and operating convenience of the cylinder.

[0072] In some embodiments provided in the present application, optionally, after the step of circumferentially connecting the end of the first cylinder and the end of the second cylinder, the method further includes: removing the fixing member and annealing the weld.

[0073] In this embodiment, after the first cylinder and the second cylinder are welded, the fixing parts are removed and the weld is annealed to improve the welding quality and thus improve the stability of the cylinder connection.

[0074] In some embodiments provided in the present application, optionally, the cylinder also includes a third cylinder and a fourth cylinder, and the method of installing the cylinder also includes: installing the third cylinder on a support roller; adjusting the number of pads and controlling the extension length of the adjusting member to adjust the spacing between the supporting rollers; installing the fourth cylinder on the supporting roller; adjusting the coaxiality of the third cylinder and the fourth cylinder; welding the outer and inner sides of the cylinder by flat welding, and driving the supporting roller to rotate by a driving member so that the end of the third cylinder and the end of the fourth cylinder are circumferentially connected.

[0075] In this embodiment, there are multiple cylinders, and the sizes of the multiple cylinders are different. The outer diameters of the third cylinder and the fourth cylinder are different from the outer diameters of the first cylinder and the second cylinder. When welding cylinders of other outer diameters, after the third cylinder is installed on the roller, the supporting position of the support roller is roughly adjusted according to the size of the fourth cylinder by adjusting the number of pads and the length of the adjusting piece. After the fourth cylinder is installed on the support roller, the coaxiality of the third cylinder and the fourth cylinder is finely adjusted so that the coaxiality of the third cylinder and the fourth cylinder is within the threshold range. Then, the outer side and the inner side of the cylinder are welded by flat welding combined with the rotation of the support roller, so that the end of the third cylinder and the end of the fourth cylinder are circumferentially connected. By adjusting the height of the pad and the spacing of the support rollers to adapt to the welding of cylinders of different specifications, the use efficiency of the cylinder assembly device is improved, the applicability of the support roller to cylinders of different outer diameters is improved, and the use range of the cylinder assembly device is expanded.

The present invention is simple to operate, and the cylinder body 20 has high precision after assembly welding, which can effectively reduce the difficulty of welding and ensure welding strength. The auxiliary device can be reused and has low cost.

[0077] The roller device is composed of a roller 100, a bearing seat of the roller 100 (i.e., the first mounting seat 410) and a roller frame 520. The roller 100 is installed on the roller frame 520 in a bolted manner. The roller 100 bearing seat of the roller 100 is equipped with an adjustment bolt (i.e., an adjustment member 720) to adjust the horizontal position of the bearing seat of the roller 100. The temporary support device is composed of a support roller 200, a shaft, a bearing seat of the support roller 200 (i.e., the second mounting seat 420), a motor, a speed reducer, a support roller frame 530, an adjustment bolt assembly, a wedge iron (i.e., a pad 730), etc. The support roller 200 is supported on the bearing seats of the support rollers 200 on both sides by shafts, and the bearing seats of the support rollers 200 are fixed to the support roller frame 530 in a bolted manner. The output end of the reducer is connected to the shaft, and the input end is connected to the motor. The reducer and the motor feet are both connected to the bearing seat of the support roller 200, and can be adjusted along with the position adjustment of the bearing seat of the support roller 200, so that the support roller 200 can always be driven.

[0078] Working principle: The roller device is used to support the roller segment cylinder, and the support adjustment device is used to support other cylinder segments that are connected to the roller segment cylinder. After the two are connected, the roller segment cylinder is used as a reference, and the cylinder position is adjusted through the temporary support device so that the two connected cylinders meet the coaxiality and other tolerance requirements. After the installation position is adjusted, the position of the two cylinders is fixed with temporary connecting channel steel, and welding is carried out. During the welding process, the driving part of the temporary support device is operated to rotate the cylinder 20 so that the welding position is always in a flat welding state to ensure the welding quality. Repeat the above-mentioned group welding process to complete the installation of the cylinder 20.

[0079] The bracket 500 has a long hole 510 at the bolt connection in the vertical direction of the axis of the support roller 200 to adjust the position of the bearing seat. Two sets of adjustment bolt assemblies are set on both sides of a single bearing seat. The adjustment bolt assembly consists of an adjustment bolt, a nut, and a steel plate with a threaded hole (i.e., a support plate 710). The three are connected by trapezoidal threads. The steel plate is welded to the bracket 500, and the horizontal position of the bearing seat is adjusted by adjusting the bolts. There are four sets of wedge irons installed under the bracket 500 to adjust the roller surface elevation of the support roller 200.

[0080] Each segment of the cylinder 20 is transported to the installation site. First, on a horizontal basis, install the roller device near the discharge end, then install the corresponding roller segment cylinder, and adjust the adjustment bolts of the bearing seat of the roller 100 so that the axis of the roller 100 and the roller segment cylinder meet the parallelism requirements. Take the above-mentioned roller segment cylinder as a reference, and continue to install other sections of the cylinder. Take the discharge end cylinder as an example to illustrate the cylinder docking installation process: first, install a temporary support device at the lower part of the discharge end cylinder installation position and roughly adjust the elevation and horizontal position, place the discharge end cylinder on the temporary support device, and use a laser tracker to measure the coaxiality between the discharge end cylinder and the roller segment cylinder. If the deviation exceeds the allowable value, fine-tune the wedge iron and the adjustment bolt assembly, that is, adjust in the vertical direction and horizontal direction respectively, so that the coaxiality meets the requirements. After the cylinder is adjusted, the two sections of the cylinder are fixed with temporary connecting channel steel, and the temporary connecting channel steel is evenly distributed around the cylinder. Weld the two cylinders at the top or bottom of the cylinder, that is, in the flat welding position, start the motor to rotate the cylinder at the discharge end, so that the welding position is always in the flat welding state. After welding, remove the temporary connecting channel steel and anneal the weld. And so on, assemble and weld each section of the cylinder. The temporary support device can adapt to different specifications of mixer cylinders by adjusting the height of the wedge iron and the spacing of the support rollers, and can be used repeatedly.
