Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of insulation pipe processing equipment, and relates to an automatic insulation pipe production device and method, in particular to a full-automatic production system and method of insulation tile shell type steam insulation pipe. BACKGROUND

[0002] The insulation tile shell type insulation pipe is a pipe insulation structure widely used in the fields of petrochemical industry and central heating, etc., which is generally composed of a steel pipe and a assembled insulation tile shell layer arranged outside the steel pipe.

[0003] In the prior art, the insulation tile shell is usually manually assembled by using prefabricated semicircular or fan-shaped hard insulation materials (such as polyurethane, rock wool or glass wool materials) along the outer wall of the steel pipe, and after the assembly is completed, the radial binding and fixing are performed by manually winding galvanized iron wire or binding tape.

[0004] A single section of steel pipe (usually 6-12 meters) needs to be assembled with multiple insulation tile shells, and the workers need to take and hold the insulation tile shells for the whole process of assembly, which has high labor intensity; moreover, it takes 30-60 minutes for a skilled worker to complete the assembly of a single section of steel pipe, and an additional 15-30 minutes for the binding process, which is difficult to meet the demand of 500-800 meters of installation progress per day in modern pipe engineering; in addition, the tightness of manual binding is inconsistent (typical value is 50-150N tension fluctuation), which easily leads to gaps (commonly 2-5mm) between the insulation layer and the steel pipe, forming a thermal bridge effect, and the actual heat loss is increased by 15%-25% compared with the theoretical value.

[0005] Through retrieval, a patent with the publication number CN115782208A discloses a technical field named pipe hard insulation tile block binding equipment, which realizes tile block binding through the ways of chuck fixing pipe, suction cup adsorbing tile block, cam divider turning, and pushing by translation cylinder, which reduces the labor intensity and improves the binding efficiency to a certain extent. However, this kind of equipment still has the following key technical deficiencies, which cannot realize the full-process automatic production of insulation tile shell type insulation pipe:

[0006] 1. The automaticity of feeding is insufficient: the insulation tile shells need to be manually filled into the arc-shaped tooling, which cannot realize the automatic grabbing, aligning and continuous feeding of stacked insulation tile shells, and still relies on manual intervention, which restricts the further improvement of production efficiency;

[0007] 2. Assembly and fixing are carried out in steps: the step-by-step mode of first completing the whole-circle insulation tile shell binding and then winding the steel band and knotting by the packing machine is adopted, the insulation tile shells lack real-time fixing during the assembly process, are easy to shift, and still have the problem of gaps between the insulation layer and the steel pipe, which affects the insulation effect;

[0008] 3. The binding accuracy is low: the packing machine adopts the method of winding two circles and knotting, the tension cannot be accurately controlled, and stress concentration exists at the knotting position, which easily leads to loose binding and still cannot avoid the generation of gaps; and the knotting position easily pierces the outer protective layer of the outer shell of the thermal insulation tile, resulting in anticorrosion failure.

[0009] Therefore, it is necessary to design a full-automatic production system and method for the thermal insulation tile shell type steam insulation pipe. SUMMARY

[0010] The purpose of the present application is to overcome the shortcomings of the prior art, provide a full-automatic production system and method for the thermal insulation tile shell type steam insulation pipe, which can further reduce labor intensity, improve production efficiency, ensure product quality, reduce production cost and be easy to implement.

[0040] 10. A fully automated production method for a heat-insulating tile-shell type steam insulation pipe, characterized in that: the method is implemented based on the fully automated production system for the heat-insulating tile-shell type steam insulation pipe according to any one of claims 1-9, and the method includes the following steps:

[0041] Step 1, Steel pipe loading and positioning: Hoist the steel pipe to be processed onto the rollers of the steel pipe loading device, move the trolley along the conveyor rail, adjust the distance between the two trolleys to match the length of the steel pipe, start the rotary drive motor, drive the rollers to rotate the steel pipe clockwise at a speed of 5-10 r / min.

[0042] Step 2, Insulation Tile Shell Loading and Positioning: The stacking cart containing the insulation tile shells is pushed to the parking space. After the photoelectric sensor detects that the stacking cart has arrived, the loading and gripping mechanism of the tile shell gripping and loading unit is activated. The X-axis direction is driven by a dual-axis reduction motor to move the transverse frame above the stacking cart via a synchronous belt. The Z-axis drive motor drives the longitudinal profile to descend. After the long-distance laser sensor detects the stacking height of the insulation tile shells, the first pneumatic gripper grabs the insulation tile shell. Then, the Z-axis rises and the X-axis moves to above the lower horizontal part of the conveying and positioning unit, placing the insulation tile shell on the conveyor belt. The conveyor belt is activated, and after the insulation tile shell is conveyed through the middle inclined part to the upper horizontal part, the pushing cylinder drives the pushing block to push the insulation tile shell towards the side stop to complete the positioning operation.

[0043] Step 3: The end of the binding strap overlaps and is pressed against the first tile shell: The binding strap binding unit is started, the binding strap feeding machine releases the binding strap, and after being buffered by the binding strap buffer frame, it is conveyed by the binding strap feeding assembly to the binding strap guide groove. The end of the binding strap overlaps on the steel pipe after passing through the guide shaft, with the end of the binding strap facing forward.

[0044] The linear electric slide of the tile shell grabbing and assembly unit drives the installation plate to move above the stacked insulation tile shells. The Z-axis drive motor drives the longitudinal profile to descend. The second pneumatic gripper grabs the insulation tile shell, moves it above the steel pipe, and presses the insulation tile shell onto the end of the binding strap to fix the end of the binding strap.

[0045] Step 4, Continuous assembly of insulation tile shells and synchronous winding of binding tape: Keep the steel pipe rotating clockwise at a uniform speed. The tile shell grabbing and assembly unit repeatedly grabs, moves, and assembles the tiles, sequentially assembling subsequent insulation tile shells onto the outer wall of the steel pipe according to the rotation angle of the steel pipe to form a complete insulation layer. At the same time, the active and driven feed rollers of the binding tape feeding assembly cooperate to continuously feed the binding tape at a rate matching the rotation speed of the steel pipe. After being guided by the guide groove, the binding tape is synchronously wound above the assembled insulation tile shells. The activation of the tile shell pressing and positioning unit causes the top and side rollers to flexibly fit against the outer wall of the insulation tile shell under the action of spring force, ensuring that the insulation tile shell is tightly fitted to the steel pipe and that the binding tape is wound flat.

[0046] Step 5, Overlapping Welding and Cutting of Cable Ties: After the steel pipe rotates one revolution, the subsequent wrapped cable ties meet the end of the initially overlapped cable ties. At this time, the welding cylinder drives the welding installation frame to extend, the lifting electric cylinder drives the welding mechanism connecting plate to descend, and the pressure tube makes the subsequent wrapped cable ties overlap with the initially overlapped cable ties. At this time, the welding head is placed at the overlap point to weld and fix the overlapped cable ties. At the same time, the angle grinder extends, and the grinding wheel cuts off the excess part of the cable ties, with a clean cut without burrs.

[0047] Step 6, Finished Product Output: After binding multiple rings of the tile shell along the length of the steel pipe as described above, the tile shell pressing and positioning unit is reset, the moving trolley slides to the finished product area, the rotary drive motor stops working, and the finished insulation pipe is lifted off the roller, completing the fully automatic production of a single section of insulation tile shell type steam insulation pipe.

[0048] The advantages and positive effects of this invention are:

[0049] 1. The fully automated production system and method for this insulated tile-shell type steam insulation pipe achieves automated production of insulated tile-shell type steam insulation pipe through the coordinated operation of steel pipe feeding device, tile feeding device and tile fixing device. It completely replaces the traditional manual assembly and fixing of insulation tile shells, greatly reduces the labor intensity of workers, and avoids the problem of damage to insulation tile shells or insulation layers caused by workers' unstable handling of insulation tile shells or uneven knots in the binding straps.

[0050] 2. This fully automated production system and method for insulated tile-shell type steam insulation pipes pioneers a production process that simultaneously assembles and binds the insulation tiles, overturning the traditional method of assembling first and then binding, or the step-by-step operation. By pressing the first insulation tile shell to fix the end of the binding tape, the subsequent insulation tile shells are continuously assembled and the binding tape is wound synchronously with the rotation of the steel pipe. Combined with the spring-loaded flexible pressure structure of the tile shell pressing and positioning unit, real-time tight contact between the insulation tile shell and the steel pipe is achieved. Actual measurements show that the gap between the insulation layer and the steel pipe has been reduced from 2-5mm in traditional processes and 1-2mm in the comparative document (CN115782208A) to less than or equal to 0.3mm, completely eliminating the thermal bridge effect. Combined with precise tension control of the binding tape at 80-100N (fluctuation ≤ ±5N), heat loss is significantly reduced.

[0051] 3. The fully automated production system and method for this insulated tile-shell type steam insulation pipe adopts a combination of welding and precise cutting technology. The overlapping points of the binding tape are welded, which greatly reduces the risk of loosening compared to manual knotting. The synchronously linked angle grinder cuts at high speed, resulting in a smooth and burr-free cut. This completely solves the problems of loosening caused by stress concentration at the knotting points and corrosion failure due to sharp ends piercing the outer protective layer, thus greatly extending the service life of the product.

[0052] 4. The fully automated production system and method for this type of insulated tile shell steam insulation pipe includes a material stacking trolley with clamping and limiting drive components that can be adapted to insulation tiles of different widths, a steel pipe feeding device with a moving trolley that can be adapted to steel pipes of different lengths, and a binding tape feeding component that can be adapted to binding tapes of different specifications by adjusting the cylinder, thus meeting the production needs of various specifications of insulation pipes. The system adopts a PLC control system, and each action is preset through the program. Workers only need to set parameters such as the length of the steel pipe through the touch screen, which is quick to learn and easy to operate, reducing the reliance on skilled workers.

Detailed Implementation

[0066] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings:

[0067] An innovative fully automatic production system for a heat-insulating tile-shell type steam insulation pipe includes a steel pipe feeding device, a tile-shell feeding device 5, and a tile-shell fixing device 4. The tile-shell feeding device is provided on a side perpendicular to the running direction of the steel pipe feeding device, and the tile-shell fixing device is provided at the rear of the tile-shell feeding device, spanning across the steel pipe feeding device.

[0068] The steel pipe feeding device is used for linear conveying and rotation of steel pipe 2. It includes a conveyor rail 1, a moving trolley 3, idlers, and a rotary drive motor. Two parallel conveyor rails are installed on the ground. Two moving trolleys are slidably mounted on the conveyor rails, and each moving trolley is equipped with two idlers driven by the rotary drive motor. To accommodate the assembly requirements of steel pipes of different diameters, a lifting plate driven by a worm gear jack is also installed on the moving trolley. The rotary drive motor and idlers are mounted on this lifting plate.

[0069] By sliding the mobile trolley along the conveyor rail, it can accommodate steel pipes of different lengths (6-12 meters); the idler rollers drive the steel pipes to rotate at a uniform speed (5-10 r / min) under the drive of the rotary drive motor, providing a stable rotation reference for the continuous assembly of the insulation tile shells and the synchronous winding of the binding tape. The rotary drive motor is linked with the feed roller drive motor of the binding tape feeding mechanism to ensure that the binding tape conveying speed and the steel pipe rotation speed are accurately matched.

[0070] The aforementioned tile shell feeding device includes a tile shell gripping and feeding unit, a conveying and positioning unit 8, and a tile shell gripping and assembly unit 10, realizing automated feeding, stacking, and continuous assembly of the insulation tile shells 36.

[0071] The aforementioned tile shell gripping and feeding unit is used to place stacked insulation tile shells onto the conveying and feeding unit. It includes a feeding mounting frame 6, a feeding gripping mechanism 7, a parking space, and a stacking cart placed in the parking space. The feeding mounting frame is a rectangular frame structure that provides installation support. The feeding gripping mechanism moves bidirectionally along the X and Z axes, and works with the first pneumatic gripper to achieve precise gripping and transfer of the insulation tile shells. A long-distance laser sensor can detect the stacking height of the insulation tile shells in real time to avoid collision damage during gripping.

The clamping and limiting rods move closer and further apart through the clamping and limiting drive assembly installed on the chassis frame. The area between pairs of limiting rods on the pallet forms a shell placement area, which corresponds to the number of first pneumatic grippers.

[0078] The clamping and limiting drive assembly includes a bidirectional ball screw slide, a slide rod, and linear bearings. Multiple bidirectional ball screw sections are installed along the length of the chassis frame at its midpoint.

These linear bearings move back and forth on the slide rod, which is mounted on the chassis frame via a mounting seat.

[0079] During operation, the insulation tile shells are stacked longitudinally in the tile shell placement area of ​​the stacking cart. The handwheel is manually cranked to move the clamping limit rods on each pallet toward each other, clamping and limiting the stacked insulation tile shells to prevent them from collapsing. Then the stacking cart is pushed into the parking space.

[0080] The aforementioned conveying and positioning unit is used for conveying and positioning the insulation tile shells. It includes a conveyor belt frame, a conveyor belt 24, a material blocking mechanism, and a material positioning mechanism. The conveyor belt frame adopts a three-section structure with a lower horizontal section 23, a middle inclined section 25, and an upper horizontal section 26 to achieve stable conveying of the insulation tile shells. The material blocking mechanism is used to limit the insulation tile shells placed on the conveyor belt to ensure that they smoothly enter the conveyor belt of the middle inclined section. The material positioning mechanism is used to position the conveyed insulation tile shells to ensure the accuracy of subsequent gripping and assembly, providing a foundation for continuous assembly.

[0081] The conveyor frame includes a lower horizontal section, a middle inclined section and an upper horizontal section.

[0091] The aforementioned tile shell pressing and positioning unit is used to press and position the insulation tile shell assembled on the steel pipe. It includes a top pressing and positioning component 33 and several sets of side pressing and positioning components 37. The top and side pressing and positioning components adopt a motor, gear, and rack drive structure, and are combined with a spring-supported roller (with a rubber anti-slip layer on the surface) to flexibly press and position the insulation tile shell from the top and circumferential directions. While avoiding damage to the insulation tile shell and the binding strap, it effectively eliminates the gap between the insulation tile shell and the steel pipe, and ensures that the binding strap is wrapped flat and tightly.

[0092] The top press-fit positioning component is installed in the middle of the crossbeam of the assembly frame, and the side press-fit positioning components are evenly distributed in a circular pattern at the arc-shaped notches of the press-fit positioning mounting plate.

[0093] The top press-fit positioning assembly includes a slider mounting plate 41, a longitudinal linear slide rail 40, a slider, a rack 39, a gear 42, a stepper motor 43, a slide rail connecting plate, a slide cylinder mounting plate 44, a transverse linear slide rail, a slide cylinder 45, a slide cylinder connecting plate 46, a spring mounting shaft, a spring, a roller connecting frame, and a roller 47.

Spring mounting shafts are installed on both sides of the vertical plate. Springs are threaded through the spring mounting shafts. A roller connecting frame is installed at the front end of the spring mounting shafts. A roller is installed on the roller connecting frame.

[0095] The aforementioned binding strap unit is used to bind the positioned insulation tile shell with binding straps. It includes a binding strap feeding mechanism, a binding strap welding mechanism, and a binding strap cutting mechanism. In this embodiment, the insulation tile shell assembled in a circle on the steel pipe is fixed with two binding straps, that is, binding straps are wrapped around both ends of the insulation tile shell. Therefore, there are two sets of corresponding functional structures, specifically:

[0096] The aforementioned strapping feeding mechanism achieves stable conveying of the strapping, including two strapping feeding machines 12, a strapping buffer frame 11, and a strapping feeding assembly. The strapping buffer frame can prevent stretching deformation during the strapping conveying process. The adjusting cylinder can precisely control the strapping conveying tension (80-100N, fluctuation range ≤±5N) by adjusting the pressure between the active feeding roller and the driven roller seat. The feeding roller drive motor is linked with the steel pipe rotation drive motor and the tile shell gripping and assembly unit to ensure that when the steel pipe rotates one revolution, the insulation tile shell is just assembled one revolution, and the strapping completes one revolution of winding and coincides with the end.

[0097] A strapping tape buffer and a strapping tape feeder are sequentially arranged from front to back at the rear of the assembly frame. A strapping tape mounting plate 53 is installed on the top of the assembly frame. Two strapping tape feeding assemblies 52 are mounted side by side on the strapping tape mounting plate. Each strapping tape feeding assembly includes a feeding mounting frame, a feeding roller drive motor, a drive feeding roller, a driven feeding roller, a driven roller seat, an adjusting cylinder, a strapping tape guide plate 51, a strapping tape turning channel 65, and a strapping tape guide groove 55. The feeding mounting frame is mounted on the strapping tape mounting plate. An active feed roller driven by a feed roller drive motor is installed on the feed mounting frame. A driven feed roller is installed above the active feed roller. The driven feed roller is installed on a driven roller seat that is driven to rise and fall by an adjusting cylinder. The gap between the active feed roller and the driven feed roller forms a feed slot. A strapping guide plate is horizontally installed at the rear end of the feed slot. A feed port that runs through the front and rear is opened on the strapping guide plate. A strapping deflection channel that conducts the strapping downward is installed at the front end of the feed slot. A strapping guide groove is installed below the strapping deflection channel.

[0098] The aforementioned binding strap welding mechanism achieves the lifting and extension of the welding head through the coordinated action of the lifting electric cylinder and the welding air cylinder. When the binding strap coincides with the initial end after rotating one revolution with the steel pipe, the overlapping joint is welded and fixed (the welding temperature is set according to the binding strap material; in this embodiment, the galvanized steel strip is 500-600℃ with a shear strength ≥100N). The assembly includes a lifting cylinder 59, a welding mechanism connecting plate 62, a slider mounting side plate 69, a welding mounting frame 64, a welding mounting plate 68, a welding cylinder 63, and two welding heads 58. The lifting cylinder is installed behind the strapping tape feeding assembly on the binding mounting plate. The lifting cylinder drives the welding mechanism connecting plate to move up and down at the bottom of the binding mounting plate. Slider mounting side plates are installed on both sides of the bottom of the welding mechanism connecting plate. A welding mounting frame is slidably mounted on the inner side of the slider mounting side plates via a linear slide. This welding mounting frame is driven to extend and retract by a welding cylinder installed at the bottom of the welding mechanism connecting plate. A pressure tube 57 is installed at the front end of the bottom of the welding mounting frame, and a welding mounting plate is installed at the rear end of the pressure tube at the bottom of the welding mounting frame. Welding heads are installed at the bottom of the welding mounting plate corresponding to the positions of the two strapping tapes. Linear bearings are installed around the lifting cylinder on the binding mounting plate, and linear shafts 60 are inserted into the linear bearings.

[0099] The aforementioned cable tie cutting mechanism is linked to the welding head. During welding, the high-speed rotating grinding wheel (3000-5000 r / min) of the angle grinder cuts off excess cable tie, resulting in a clean, burr-free cut, avoiding the damage to the outer protective layer caused by the sharp ends of traditional wire. It includes two angle grinders 54 and two cable tie guide shafts 56. Two angle grinders are mounted side-by-side on the upper part of the welding mounting frame. A guide shaft mounting bracket 67 is installed at the front end of each angle grinder, mounted on the welding mounting frame. Two cable tie guide shafts are arranged vertically at intervals on the guide shaft mounting bracket. Each cable tie guide shaft has a limiting groove to limit the overlapping position of the cable tie on the steel pipe. The grinding wheel 66 of the angle grinder is placed between the two cable tie guide shafts. The cable tie passes sequentially around the two guide shafts. Under the pressure of the pressure tube, the cable tie is taut between the two guide shafts. At this point, the angle grinder extends to complete the cutting of the cable tie.

[0100] An innovative fully automated production method for heat-insulating tile-shell type steam insulation pipes includes the following steps:

[0101] Step 1, Steel pipe loading and positioning: Hoist the steel pipe to be processed onto the rollers of the steel pipe loading device, move the trolley along the conveyor rail, adjust the distance between the two trolleys to match the length of the steel pipe, start the rotary drive motor, drive the rollers to rotate the steel pipe clockwise at a speed of 5-10 r / min.

[0102] Step 2, Insulation tile shell feeding and stacking: Push the stacking cart with the insulation tile shells to the parking space. After the photoelectric sensor detects that the stacking cart has arrived, the feeding and grabbing mechanism of the tile shell grabbing and feeding unit is started.

[0103] The X-axis direction is driven by a dual-axis geared motor to move the transverse frame to the top of the stacking car. The Z-axis drive motor drives the longitudinal profile to descend. After the long-distance laser sensor detects the stacking height of the insulation tile shells, the first pneumatic gripper simultaneously grabs 3 insulation tile shells, then rises and moves to the lower horizontal part above the conveyor unit, and places the insulation tile shells on the conveyor belt.

[0104] When the conveyor belt starts, the insulation tile shell is conveyed through the lower horizontal section, and then through the middle inclined section to the upper horizontal section. The pushing cylinder drives the pushing block to push the insulation tile shell towards the side baffle to complete the insertion operation and wait for it to be grabbed.

[0105] Step 3: The end of the binding strap overlaps and is pressed against the first tile shell: The binding strap binding unit is started, the binding strap feeding machine releases the binding strap, and after being buffered by the binding strap buffer frame, it is conveyed by the binding strap feeding assembly to the binding strap guide groove. The end of the binding strap overlaps on the steel pipe after passing through the guide shaft, with the end of the binding strap facing forward.

[0106] Adjust the cylinder to drive the driven roller seat to rise and fall, and adjust the pressure between the active feed roller and the driven roller seat to control the tension of the binding tape conveyor at 80-100N; the active feed roller and the driven feed roller rotate in coordination to guide the binding tape onto the steel pipe through the binding tape guide plate, the turning channel and the guide groove.

[0107] The linear electric slide of the tile shell gripping and assembly unit drives the mounting plate to move above the neatly stacked insulation tile shells. The Z-axis drive motor drives the longitudinal profile to descend, and the second pneumatic gripper grips and clamps the insulation tile shell; then it moves above the steel pipe, as... Figure 11 As shown in Figure a, the insulation tile shell is precisely attached to the end of the binding strap on the outer wall of the steel pipe. The second pneumatic gripper is released, and the end of the binding strap is firmly pressed and fixed by the weight of the insulation tile itself and the pressure of the tile shell pressing and positioning unit.

[0108] Step 4, continuous assembly of the insulation tile shell and simultaneous wrapping with binding straps: (e.g.) Figure 11 As shown in b and c, the steel pipe rotates clockwise at a constant speed. The tile shell grabbing and assembling unit repeatedly grabs, moves, and assembles the tiles, sequentially assembling subsequent insulation tiles onto the outer wall of the steel pipe according to the rotation angle of the steel pipe to form a complete insulation layer. At the same time, the active and passive feed rollers of the binding tape feeding assembly cooperate to continuously feed the binding tape at a rate matching the rotation speed of the steel pipe. After being guided by the guide groove, the binding tape is synchronously wrapped above the assembled insulation tile shells. The tile shell pressing and positioning unit is activated, and the top and side rollers flexibly fit against the outer wall of the insulation tile shell under the action of spring force, ensuring that the insulation tile shell is tightly fitted to the steel pipe and that the binding tape is wrapped flat.

[0109] Step 5, overlap welding and cutting of the cable ties: (e.g.) Figure 11 As shown in d, after the steel pipe rotates one revolution, the subsequently wrapped binding straps meet the end of the initially placed binding straps, and the first insulation tile shell returns to its initial position. At this time, the welding cylinder drives the welding installation frame to extend, and the lifting electric cylinder drives the welding mechanism connecting plate to descend, as shown in d. Figure 11 As shown in e, the pressure tube makes the subsequently wrapped binding tape overlap with the initially overlapped binding tape. At this time, the welding head is placed at the overlap point to weld and fix the overlap of the binding tape. At the same time, the angle grinder extends and the grinding wheel cuts off the excess part of the binding tape, and the cut is flat and burr-free.

[0110] Step 6, Finished Product Output: After binding multiple rings of the tile shell along the length of the steel pipe as described above, the tile shell pressing and positioning unit is reset, the moving trolley slides to the finished product area, the rotary drive motor stops working, and the finished insulation pipe is lifted off the roller, completing the fully automatic production of a single section of insulation tile shell type steam insulation pipe.

[0111] This invention innovatively constructs an integrated production line for "automatic gripping, conveying, assembly, binding, welding, and cutting of thermal insulation tile shells," overcoming the inefficiency of traditional manual assembly and binding methods, as well as the semi-automation bottleneck of the comparative patent (CN115782208A) which requires manual filling of the tile shells. Through laser positioning of the tile shell gripping and feeding unit, collaborative design of pneumatic grippers, and adaptive limiting structure of the stacking cart, unmanned continuous feeding of stacked thermal insulation tile shells is achieved. The moving trolley of the steel pipe feeding device is linked with the rotating rollers, eliminating the need for manual positioning. Workers only need to complete auxiliary operations such as steel pipe hoisting, stacking cart pushing, and finished product lifting, reducing labor intensity by more than 90% and completely avoiding occupational diseases such as lumbar muscle strain caused by long-term lifting and assembling of tile shells. Simultaneously, the precise mechanical gripping significantly reduces raw material loss.

[0112] Although embodiments and drawings of the present invention have been disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, variations and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.

7. A fully automated production method for a heat-insulating tile-shell type steam insulation pipe, characterized in that: This method is implemented based on the fully automated production system of the heat-insulating tile-type steam insulation pipe according to any one of claims 1-6, and the method includes the following steps: Step 1, Steel pipe (2) loading and positioning: The steel pipe (2) to be processed is hoisted onto the roller of the steel pipe loading device, the moving trolley (3) slides along the conveying slide rail (1), the distance between the two moving trolleys (3) is adjusted to match the length of the steel pipe (2), the rotary drive motor is started, and the roller drives the steel pipe (2) to rotate clockwise at a speed of 5-10 r / min. Step 2, Insulation tile shell (36) loading and positioning: Push the stacking cart containing the insulation tile shell (36) to the parking space. After the photoelectric sensor (77) detects that the stacking cart has arrived, the loading and gripping mechanism (7) of the tile shell gripping and loading unit is activated. In the X-axis direction, the synchronous belt (13) driven by the dual-axis reduction motor (19) moves the transverse frame (20) above the stacking cart. The Z-axis drive motor drives the longitudinal profile (27) to descend. The long-distance laser sensor (15) detects the insulation tile shell (36). After stacking to the required height, the first pneumatic gripper (16) grabs the insulation tile shell (36), then the Z-axis rises and the X-axis moves to the upper horizontal part (23) of the conveying and positioning unit (8), and the insulation tile shell (36) is placed on the conveyor belt (24); the conveyor belt (24) starts, and the insulation tile shell (36) is conveyed to the upper horizontal part (26) through the middle inclined part (25). Then, the pushing cylinder drives the pushing block (31) to push the insulation tile shell (36) towards the side baffle (28) to complete the positioning operation. Step 3: The end of the binding strap (61) is placed and pressed against the first tile shell: The binding strap binding unit (34) is started, the binding strap feeding machine (12) releases the binding strap (61), and after being buffered by the binding strap buffer frame (11), it is conveyed by the binding strap feeding assembly (52) to the binding strap guide groove (55). The end of the binding strap (61) is placed on the steel pipe (2) after passing through the guide shaft, with the end of the binding strap (61) facing forward; The linear electric slide of the tile shell grabbing and assembly unit (10) drives the mounting plate (18) to move above the stacked insulation tile shells (36), the Z-axis drive motor drives the longitudinal profile (27) to descend, the second pneumatic gripper (29) grabs the insulation tile shell (36), moves it above the steel pipe (2) and presses the insulation tile shell (36) onto the end of the binding strap (61) to achieve the fixation of the end of the binding strap (61); Step 4, continuous assembly of insulation tile shells (36) and synchronous winding of binding tape (61): Keep the steel pipe (2) rotating clockwise at a uniform speed. The tile shell grabbing and assembly unit (10) repeatedly grabs, moves and assembles the subsequent insulation tile shells (36) in sequence according to the rotation angle of the steel pipe (2) to form a complete insulation layer. At the same time, the active feed roller and the driven feed roller of the binding tape feeding assembly (52) cooperate to continuously feed the binding tape (61) at a rate matching the rotation speed of the steel pipe (2). After being guided by the guide groove, the binding tape is synchronously wound above the assembled insulation tile shells (36). The activation of the tile shell pressing and positioning unit makes the top and side rollers (47) flexibly fit against the outer wall of the insulation tile shell (36) under the elastic force of the spring (50), ensuring that the insulation tile shell (36) is tightly fitted to the steel pipe (2) and the binding tape (61) is wound flat. Step 5, overlapping welding and cutting of binding straps (61): After the steel pipe (2) rotates once, the subsequent wrapped binding straps (61) meet the end of the initially placed binding straps (61). At this time, the welding cylinder (63) drives the welding installation frame (64) to extend, the lifting electric cylinder (59) drives the welding mechanism connecting plate (62) to descend, and the pressure tube (57) makes the subsequent wrapped binding straps (61) overlap with the initially placed binding straps (61). At this time, the welding head (58) is placed at the overlap point to weld and fix the overlap of the binding straps (61); at the same time, the angle grinder (54) extends, and the grinding wheel (66) cuts off the excess part of the binding straps (61), and the cut is flat and burr-free. Step 6, finished product output: After binding multiple rings of the tile shell along the length of the steel pipe (2) in the above manner, the tile shell pressing and positioning unit is reset, the moving trolley (3) slides to the finished product area, the rotation drive motor stops working, and the finished insulation pipe is lifted off the roller, thus completing the fully automatic production of a single section of insulation tile shell (36) type steam insulation pipe.
