Description

Technical Field

[0001] This invention relates to the field of steel structure processing equipment technology, and in particular to an intelligent mobile machining center and processing method. Background Technology

[0002] In the field of steel structure fabrication equipment, especially for the traditional processing of structural steel components, the process involves cutting, drilling, and welding in a fixed factory, followed by transporting the finished components to the construction site for installation. This factory prefabrication and on-site installation model has the following inherent drawbacks: First, the transportation cost of large components is high, and extra-long or extra-heavy components require special transportation permits, resulting in long cycles and high costs; second, on-site installation and factory processing are often disconnected, and if design changes or dimensional deviations occur, components need to be returned to the factory for modification or recut on-site, seriously affecting the construction period; third, a large number of temporary processing equipment and personnel are often required at the construction site, increasing management difficulty and safety risks. Summary of the Invention

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an intelligent mobile machining center that is highly adaptable to different sites, has the ability to be deployed quickly, and can meet the processing needs of different workpieces.

[0004] The present invention also proposes a processing method using the above-mentioned intelligent mobile machining center.

[0005] An intelligent mobile machining center according to a first aspect embodiment of the present invention includes: The housing unit includes a shell, and the shell has a processing space inside; A processing unit, disposed within the processing space, is used to process the workpiece; The loading unit includes a loading rack and a feeding trolley. The loading rack is rotatably mounted on the inlet / outlet side of the housing. The loading rack is folded into the housing during transport and flipped down to be flush with the bottom surface of the housing during operation. The feeding trolley is used to transport the workpieces on the loading rack back and forth within the processing space.

[0006] According to an embodiment of the present invention, an intelligent mobile machining center has at least the following beneficial effects: All equipment is integrated into a movable housing. The structural design, which allows for folding during transport and flipping downwards during operation, not only meets the size requirements for road transport but also enables rapid deployment upon arrival at the site. This eliminates the component transportation link between traditional factory prefabrication and on-site installation, effectively reducing transportation costs and shortening the construction cycle. It is particularly suitable for construction projects with tight schedules, limited space, or in remote areas. The automatic loading, feeding, and unloading of workpieces is achieved through the back-and-forth transport of the material carrier between the loading rack and the processing space, replacing traditional manual handling or overhead crane methods. This reduces the labor intensity of workers, improves operational efficiency, and avoids the safety hazards associated with manual operation. The feeding vehicle operates under controlled conditions on the track throughout the entire process, ensuring a smooth and reliable conveying process. The loading rack is rotatably mounted on the inlet and outlet sides of the housing. During transportation, it folds upward to reduce the transport volume, and during operation, it flips downward to be flush with the bottom surface. It can be deployed without additional hoisting equipment, enabling rapid on-site deployment and adapting to different construction site operating conditions. The processing unit and the loading unit are integrated into a single box, with the processing space also serving as a conveying channel. The compact structure significantly reduces the floor space required compared to traditional fixed factory production lines, and eliminates the need for factory foundation construction, further reducing the initial investment cost of the project.

[0007] According to some embodiments of the present invention, the feeding unit further includes a positioning component, which includes a first position sensor and a second position sensor. The first position sensor is disposed in the processing space, and the second position sensor is disposed on the inlet / outlet side of the housing, for detecting whether the feeding trolley has reached the processing start position. Specifically, the processing unit only begins processing when the first position sensor detects that the feeding trolley has arrived at its position; the second position sensor is used to detect whether the feeding trolley has reached the loading position, and the loading rack is only allowed to perform the loading action when the second position sensor detects that the feeding trolley has arrived at its position.

[0008] According to some embodiments of the present invention, the positioning component further includes a locking cylinder, and a mating part is provided on the bottom of the feeding carriage corresponding to the position of the locking cylinder. The mating part is a positioning hole opened on the bottom of the feeding carriage or a positioning block provided on the bottom of the feeding carriage. After the feeding carriage reaches the processing position, the piston rod of the locking cylinder extends and inserts into the positioning hole or abuts against the positioning block to lock the feeding carriage in the processing position.

[0009] According to some embodiments of the present invention, the feeding unit further includes support legs, which are detachably mounted on the inlet / outlet side of the housing. The support legs extend along the conveying direction of the feeding trolley, and the upper surface of the support legs forms a support track for the rollers at the bottom of the feeding trolley to roll. When the feeding trolley is feeding, the rollers at the bottom extend outward from the bottom surface of the housing and roll onto the support legs. The support legs provide support for the feeding trolley and the workpiece it carries. Multiple support legs are provided, and each support leg has an independent adjustment seat at its bottom. Each adjustment seat is used to independently adjust the support height of the corresponding support leg relative to the ground. When each adjustment seat is adjusted independently, the height of the upper surface of the support leg changes accordingly to keep the upper surfaces of each support leg at the same horizontal plane.

[0010] According to some embodiments of the present invention, the loading rack is provided with a clearance portion, which is a notch opened at the position of the support leg on the loading rack. The notch extends along the flipping direction of the loading rack, and the support leg passes through the notch, so that when the loading rack is flipped downward to be flush with the bottom surface of the housing, the support leg is accommodated in the notch, so as to avoid interference between the loading rack and the support leg.

[0011] According to some embodiments of the present invention, the bottom of the feeding cart is driven by a sprocket transmission mechanism. The sprocket transmission mechanism includes a drive motor, a universal joint transmission assembly, and two sets of sprocket assemblies. The two sets of sprocket assemblies are respectively disposed on both sides of the bottom of the feeding cart along the width direction of the housing. Each set of sprocket assemblies includes a driving sprocket, a driven sprocket, and a chain tensioned between the driving sprocket and the driven sprocket. The chain is fixedly connected to the feeding cart. The output end of the drive motor is connected to the driving sprockets on both sides through the universal joint transmission assembly. The drive motor synchronously distributes power to the driving sprockets on both sides through the universal joint transmission assembly, so that the chains on both sides simultaneously pull the feeding cart to move.

[0012] According to some embodiments of the present invention, the feeding rack includes a plurality of independently arranged sub-frames, each of which is rotatably arranged on the inlet / outlet side of the housing. Each of the sub-frames can be independently flipped and folded independently into the housing during transportation, and independently flipped downwards to be flush with the bottom surface of the housing during operation.

[0013] According to some embodiments of the present invention, the feeding unit further includes a plurality of driving cylinders, each of the driving cylinders being fixedly disposed within the housing and located above the feeding trolley, and the driving cylinders being arranged at intervals along the conveying direction of the feeding trolley; when the piston rod of each driving cylinder extends downward, it presses against the upper surface of the workpiece to press and position the workpiece on the feeding trolley; at least a portion of the piston rods of the driving cylinders push the workpiece along the conveying direction of the feeding trolley to push the workpiece to the processing position.

[0014] According to some embodiments of the present invention, the processing unit includes a cantilevered steel section laser cutting machine, a laser, a chiller, an air compressor, a voltage stabilizer, and an electrical control cabinet; the laser, the chiller, the air compressor, the voltage stabilizer, and the electrical control cabinet are all disposed within the processing space of the housing; The cantilevered steel section laser cutting machine is located at one end of the processing space along its length. The laser is located at the front end of the cantilevered steel section laser cutting machine. The chiller, the air compressor, the voltage stabilizer, and the electrical control cabinet are located on the same side of the cantilevered steel section laser cutting machine. The cantilevered steel section laser cutting machine, the laser, the chiller, the air compressor, the voltage stabilizer, and the electrical control cabinet are arranged compactly within the processing space to leave a channel for the feeding trolley to transport the workpiece along the length of the housing within the processing space.

[0015] The processing method according to a second aspect of the present invention, applied to an intelligent mobile processing center according to a first aspect embodiment, wherein the loading unit includes support legs and a positioning component, includes the following steps: Step S1: Start the equipment by activating each component of the processing unit, so that the processing unit is in a ready-to-process state; Step S2: Input processing instructions, and input the processing content and processing parameters through the control system; Step S3: Loading. Flip the loading rack downwards until it is flush with the bottom surface of the housing. The feeding trolley drives out from the processing space along the support legs to the loading rack. Then, place the workpiece to be processed on the feeding trolley. Step S4: Feeding and positioning. The feeding carriage carries the workpiece and moves it to the processing position along the support legs and the processing space. The positioning component detects whether the feeding carriage has reached the processing position. When the feeding carriage is detected to be in place, the feeding carriage stops and locks. Step S5: Processing, the processing unit performs processing operations on the workpiece according to the processing instructions; Step S6: Unloading. After the processing is completed, the feeding trolley is unlocked and carries the processed workpiece out of the processing space.

[0016] The processing method according to the embodiments of the present invention has at least the following beneficial effects: Through the complete automated process design of steps S1 to S6, a continuous flow operation mode is formed from equipment start-up, instruction input, automatic feeding, automatic feeding and positioning, automatic processing to automatic unloading. The entire process of feeding, conveying, positioning, processing and unloading is automated, replacing the manual marking and manual operation of equipment in traditional mobile factories, which greatly improves processing efficiency and reduces labor costs. The feeding trolley drives out along the support legs to the feeding rack to receive the workpiece, and then moves along the support legs and processing space to the processing position. The support legs provide extended travel tracks for the extension and retraction of the feeding trolley, and at the same time provide reliable support for the feeding trolley and the heavy workpiece it carries during the feeding process, ensuring the smooth operation and safety of the 12m long and 1 ton or more steel main components during the loading and unloading process.

[0024] Reference Figures 1 to 6 An intelligent mobile machining center, comprising: The housing unit includes a shell 100, and the shell 100 has a processing space inside; The processing unit 140 is disposed in the processing space and is used to process the workpiece 150; The loading unit includes a loading rack 120 and a feeding cart 250. The loading rack 120 is rotatably mounted on the inlet / outlet side of the housing 100. The loading rack 120 is folded into the housing 100 during transport and flipped down to be flush with the bottom surface of the housing 100 during operation. The feeding cart 250 is used to transport the workpiece 150 on the loading rack 120 back and forth within the processing space.

[0025] In transport mode, the loading rack 120 flips upward and folds to the side of the shell 100, forming a container shape for easy road transport and hoisting. Upon arrival at the construction site, the loading rack 120 flips downward until it is flush with the bottom surface of the shell 100, forming a loading and unloading platform extending to the outside of the shell 100.

[0026] During operation, the feeding carriage 250 moves from the processing space of the housing 100 along the support legs 110 to the loading rack 120. The workpiece 150 to be processed is placed on the feeding carriage 250 via a traveling crane or conveyor roller, or directly placed on the loading rack 120 and then received by the feeding carriage 250. The feeding carriage 250 carries the workpiece 150 along the support legs 110 and the processing space to the processing position. The positioning component detects whether the feeding carriage 250 is in position. Once in position, the feeding carriage 250 stops and locks, ensuring that the workpiece 150 is fixed in position during processing. The processing unit 140 performs cutting, drilling, beveling, and other processing operations on the workpiece 150 according to preset processing instructions. After processing is completed, the feeding carriage 250 is unlocked, carrying the processed workpiece 150 out of the processing space, and begins the next workpiece 150 loading cycle.

[0027] Throughout the process, the enclosure provides a stable installation foundation and protective barrier for each piece of equipment. The processing space can also serve as a conveying channel for the workpiece 150. The loading rack 120 and the feeding cart 250 work together to automatically load and unload the workpiece 150. The processing unit 140 automatically executes the processing operation according to the instructions, thus realizing the entire process of "transportation - unfolding - loading - processing - unloading - gathering".

[0028] All equipment is integrated into a standard shipping container. The 120-inch loading rack features a flip-up structure, folding upwards to blend seamlessly with the container during transport, meeting road transport size requirements. During operation, it flips downwards and unfolds for quick deployment, eliminating the need for complex on-site installation. The equipment can be flexibly moved along with the construction project, eliminating the component transportation link between traditional factory prefabrication and on-site installation, effectively reducing transportation costs and shortening the construction cycle.

[0029] By integrating all equipment into a mobile container, and utilizing the folding design of the loading rack 120 for transport and the downward flipping design for operation, the system not only meets the size requirements for road transport but also enables rapid deployment upon arrival at the site. This eliminates the component transportation link between traditional factory prefabrication and on-site installation, effectively reducing transportation costs and shortening the construction cycle. It is particularly suitable for construction projects with tight schedules, limited space, or in remote areas. The material delivery vehicle 250 automatically loads, feeds, and unloads workpieces 150 by transporting them back and forth between the loading rack 120 and the processing space. This replaces traditional manual handling or overhead crane transportation methods, reducing the labor intensity of workers, improving work efficiency, and avoiding the safety hazards associated with manual operation. The feeding trolley 250 operates under controlled conditions on the track throughout the entire process, ensuring a smooth and reliable conveying process. The loading rack 120 is rotatably mounted on the inlet and outlet side of the housing 100. During transportation, it folds upward to reduce the transportation volume, and during operation, it flips downward to be flush with the bottom surface. It can be deployed without additional hoisting equipment, enabling rapid on-site deployment and adapting to different construction site operating conditions. The processing unit 140 and the loading unit are integrated into a single box, with the processing space also serving as a conveying channel. The compact structure significantly reduces the floor space compared to traditional fixed factory production lines and eliminates the need for factory foundation construction, further reducing the initial investment cost of the project.

[0030] The feeding unit also includes a positioning component, which includes a first position sensor 180 and a second position sensor 190. The first position sensor 180 is disposed in the processing space, and the second position sensor 190 is disposed on the inlet / outlet side of the housing 100, for detecting whether the feeding carriage 250 has reached the processing start position. Specifically, the processing unit 140 only starts processing when the first position sensor 180 detects that the feeding carriage 250 has arrived at its position; the second position sensor 190 is used to detect whether the feeding carriage 250 has arrived at the loading position, and the loading rack 120 is only allowed to perform the loading action when the second position sensor 190 detects that the feeding carriage 250 has arrived at its position.

[0031] By installing a positioning assembly consisting of a first position sensor 180 and a second position sensor 190 in the feeding unit, precise detection and interlocked control of the movement position of the feeding car 250 are achieved. The specific working principle is as follows: At least two detection points are set along the entire movement path of the feeding car 250: one is the loading position on the inlet / outlet side (second position sensor 190), and the other is the processing start position in the processing space (first position sensor 180). The two sensors detect whether the feeding car 250 has reached the corresponding working position and feed the detection signals back to the control system in real time.

[0032] When the feeding trolley 250, carrying the finished workpiece 150, travels from the processing space outwards to the loading / unloading side for unloading, or drives out empty to the loading position to receive a new workpiece 150, the second position sensor 190 detects whether the feeding trolley 250 has reached the loading position. Only after the second position sensor 190 outputs a position signal will the control system allow the operator to perform loading / unloading operations. That is, by connecting the external conveyor belt to the feeding trolley 250, a crane is used to lift the workpiece 150 to be processed onto the conveyor belt to complete the loading / unloading; or the feeding trolley 250 transports the finished workpiece 150 to the conveyor belt, and then the crane lifts it off the conveyor belt. This interlocking mechanism prevents the loading / unloading equipment (such as the conveyor belt, crane, etc.) from malfunctioning and colliding with the feeding trolley 250 if it has not completely withdrawn.

[0033] When the feed carriage 250 carrying the workpiece 150 moves from the inlet / outlet side into the processing space, the first position sensor 180 detects whether the feed carriage 250 has reached the processing start position. Only after the first position sensor 180 confirms that the feed carriage 250 is in place will the control system allow the processing unit 140 to start the processing program, ensuring that the workpiece 150 is accurately positioned before processing, and avoiding processing position deviation or even equipment damage due to the feed carriage 250 not being in place.

[0034] Through the coordinated operation of the two sensors, the feeding car 250 achieves precise detection and process interlocking at the two key nodes of loading and processing, ensuring that the entire loading, unloading and processing process is carried out in an orderly and safe manner.

[0035] By placing the first position sensor 180 within the processing space and the second position sensor 190 on the infeed / outfeed side, a logical interlock is established between the position detection signal of the feeding carriage 250 and the start-up and loading / unloading operations of the processing unit 140. When the feeding carriage 250 has not reached the loading position, the external conveyor belt cannot connect with the feeding carriage 250, and the crane cannot perform the lifting operation of the workpiece 150, preventing collisions caused by malfunctions in the loading / unloading equipment when the feeding carriage 250 has not fully retracted. Similarly, the processing unit 140 cannot start when the feeding carriage 250 has not reached the processing start position, preventing empty cutting or gun collisions when the feeding carriage 250 is not in position. This effectively avoids safety accidents caused by operational errors, ensuring the safety of the equipment and operators. The first position sensor 180 accurately detects whether the feeding carriage 250 has reached the processing start position, ensuring that the workpiece 150 is accurately positioned within the processing space before allowing the processing unit 140 to start. This avoids processing position deviations caused by positioning errors of the feeding carriage 250, providing a hardware foundation for ensuring cutting accuracy.

[0036] The positioning assembly also includes a locking cylinder 170. A mating part 200 is provided at the bottom of the feeding carriage 250 corresponding to the position of the locking cylinder 170. The mating part 200 is either a positioning hole opened at the bottom of the feeding carriage 250 or a positioning block provided at the bottom of the feeding carriage 250. After the feeding carriage 250 reaches the processing position, the piston rod of the locking cylinder 170 extends and inserts into the positioning hole or abuts against the positioning block, locking the feeding carriage 250 in the processing position.

[0037] The positioning assembly also includes a locking cylinder 170, and a mating part 200 (positioning hole or positioning block) is provided on the bottom of the feeding carriage 250 corresponding to the position of the locking cylinder 170. When the feeding carriage 250 carrying the workpiece 150 moves from the inlet / outlet side into the processing space, the first position sensor 180 first detects whether the feeding carriage 250 has entered the processing space. Then, the control system controls the feeding carriage 250 to decelerate and precisely move to the processing position. After the feeding carriage 250 reaches the processing position, the control system sends an execution signal to the locking cylinder 170. The piston rod of the locking cylinder 170 extends and inserts into the positioning hole at the bottom of the feeding carriage 250, or abuts against the positioning block at the bottom of the feeding carriage 250, firmly locking the feeding carriage 250 in the processing position and preventing displacement of the feeding carriage 250 due to cutting vibration, equipment impact, or misoperation during processing. After locking is completed, the locking cylinder 170 sends a locking signal to the control system. Only after the control system confirms that the feed carriage 250 has been reliably locked can the processing unit 140 start the processing program. After processing is completed, the control system first sends an unlocking signal to the locking cylinder 170, the piston rod returns to its original position, and the feed carriage 250 can exit the processing space after being unlocked.

[0038] By engaging or abutting with the positioning hole or block at the bottom of the feeding carriage 250 through the extension of the piston rod of the locking cylinder 170, the feeding carriage 250 is firmly locked in the processing position. This effectively avoids slight displacement of the feeding carriage 250 caused by cutting vibration, equipment start-up and shutdown impacts, etc., during processing, ensuring that the relative position of the laser cutting head and the workpiece 150 remains constant throughout the processing. This provides mechanical assurance for ensuring a positioning accuracy of ±0.15mm / m and a repeatability of ±0.05mm / m. By combining the position sensor with the locking cylinder 170, the feeding carriage 250 is first detected and stopped by the sensor, and then mechanically locked by the locking cylinder 170, realizing a dual positioning method of mechanical and electrical. Compared with the solution that relies solely on sensor signals to stop the feeding carriage 250, mechanical locking can prevent the feeding carriage 250 from accidentally loosening or shifting during processing due to hydraulic or pneumatic pressure fluctuations, electrical signal drift, etc., greatly improving positioning reliability.

[0039] Reference Figure 3 , Figure 5 and Figure 6The feeding unit also includes support legs 110, which are detachably installed on the inlet / outlet side of the housing 100. The support legs 110 extend along the conveying direction of the feeding trolley 250, and the upper surface of the support legs 110 forms a support track for the rollers 260 at the bottom of the feeding trolley 250 to roll. When the feeding trolley 250 is feeding, the rollers 260 at the bottom extend outward from the bottom surface of the housing 100 and roll on the support legs 110. The support legs 110 provide support for the feeding trolley 250 and the workpiece 150 it carries. Multiple support legs 110 are provided, and each support leg 110 has an independent adjustment seat 210 at its bottom. Each adjustment seat 210 is used to independently adjust the support height of the corresponding support leg 110 relative to the ground. When each adjustment seat 210 is adjusted independently, the height of the upper surface of the support leg 110 changes accordingly to keep the upper surfaces of each support leg 110 at the same horizontal plane.

[0040] The feeding unit is equipped with support legs 110. The support legs 110 are detachably installed on the inlet / outlet side of the housing 100 and extend outward along the conveying direction of the feeding trolley 250. The upper surface of the support legs 110 forms a support track for the bottom rollers 260 of the feeding trolley 250 to roll, providing a walking support surface for the feeding trolley 250 to move outside the housing 100 and bridging the height difference between the bottom surface of the housing 100 and the ground at the construction site.

[0041] During transportation, the outriggers 110 are removed from the housing 100 to reduce the transportation volume and facilitate container hoisting and road transport. Upon arrival at the construction site, each outrigger 110 is installed in its corresponding mounting position on the material inlet / outlet side of the housing 100. Depending on the flatness of the ground at the construction site, the support height of each outrigger 110 relative to the ground is adjusted using the independent adjusting seat 210 at the bottom of each outrigger 110, so that the upper surfaces of each outrigger 110 are on the same horizontal plane, forming a continuous and flat traveling track.

[0042] During operation, the feeding trolley 250 moves from the processing space of the housing 100 towards the loading / unloading side. The rollers 260 at its bottom roll from the bottom surface of the housing 100 to the upper surface of the support leg 110 (i.e., rolling outwards from inside the housing 100 and pressing against the support leg 110). The support leg 110 provides stable external support for the feeding trolley 250 and the workpiece 150 it carries, enabling the feeding trolley 250 to travel along the upper surface of the support leg 110 to the loading rack 120 for loading or unloading. After loading is completed, the feeding trolley 250, carrying the workpiece 150, rolls in the opposite direction along the upper surface of the support leg 110 into the housing 100, entering the processing space for subsequent processing.

[0043] By using the aforementioned outrigger 110 to "remove during transport and install and adjust during operation", the material delivery vehicle 250 can move freely between the outside and inside of the shell 100, solving the technical problem that the material delivery vehicle 250 cannot drive directly out of the shell 100 due to the height difference between the bottom of the container and the ground.

[0044] Reference Figure 1 and Figure 4 The loading rack 120 is provided with a clearance part 130, which is a notch opened at the position of the support leg 110 of the loading rack 120. The notch extends along the flipping direction of the loading rack 120, and the support leg 110 passes through the notch so that when the loading rack 120 is flipped down to be flush with the bottom surface of the housing 100, the support leg 110 is accommodated in the notch so as to avoid interference between the loading rack 120 and the support leg 110.

[0045] With outriggers 110 installed on the inlet / outlet side of the housing 100, their upper surfaces form support tracks, allowing the rollers 260 at the bottom of the feeding trolley 250 to roll directly from the bottom surface of the housing 100 onto the outriggers 110. This enables seamless movement of the feeding trolley 250 between the external ground and the internal processing space of the housing 100, effectively extending the track within the processing space to the outside of the housing 100. This solves the technical problem of the feeding trolley 250 being unable to directly exit the housing 100 due to the height difference between the bottom surface of the container and the construction site ground. By installing independent adjustment seats 210 at the bottom of each outrigger 110, the support height of each outrigger 110 can be adjusted according to the actual flatness of the construction site ground, ensuring that the upper surfaces of each outrigger 110 remain on the same horizontal plane, forming a flat track. Even if the construction site ground has slopes or unevenness, independent adjustments ensure stable movement of the feeding trolley 250, making it particularly suitable for construction environments with complex ground conditions, such as construction sites. The outriggers 110 are detachably installed on the housing 100. They can be removed during transportation to reduce the transport volume and meet the clearance requirements for container road transport. They can be quickly installed and put into use during operation without the need for hardening or leveling the ground at the construction site.

[0046] The bottom of the feeding cart 250 is driven by a sprocket transmission mechanism, which includes a drive motor 220, a universal transmission assembly 230, and two sets of sprocket assemblies 240. The two sets of sprocket assemblies 240 are respectively arranged on both sides of the bottom of the feeding cart 250 along the width direction of the housing 100. Each set of sprocket assemblies 240 includes a driving sprocket, a driven sprocket, and a chain tensioned between the driving sprocket and the driven sprocket. The chain is fixedly connected to the feeding cart 250. The output end of the drive motor 220 is connected to the driving sprockets on both sides through the universal transmission assembly 230. The drive motor 220 synchronously distributes power to the driving sprockets on both sides through the universal transmission assembly 230, so that the chains on both sides can pull the feeding cart 250 to move simultaneously.

[0047] Reference Figure 2The drive motor 220 is fixedly installed inside the housing 100, and its output end is connected to the drive sprockets on both sides of the bottom of the feeding trolley 250 via the universal transmission assembly 230. After the drive motor 220 starts, the output power is synchronously transmitted to the drive sprockets on both sides via the universal transmission assembly 230. The drive sprockets drive the chain to rotate. Since the chain is fixedly connected to the feeding trolley 250, the chains on both sides simultaneously pull the feeding trolley 250 to move along the conveying direction.

[0048] Since the two sets of sprocket assemblies 240 are respectively located on both sides of the bottom of the feeding carriage 250 along the width direction of the housing 100, and both sets of sprocket assemblies 240 are synchronously driven by the same drive motor 220 through the universal transmission assembly 230, the left and right sides of the feeding carriage 250 always receive equal driving force and the same movement speed, ensuring that the feeding carriage 250 runs synchronously on both sides during the movement and does not tilt.

[0049] The universal drive assembly 230 plays two main roles in this process: first, it diverts the power of the drive motor 220 from the motor output end to the left and right sides of the bottom of the feeding carriage 250; second, it adapts to the installation position deviation and angle deviation between the drive motor 220 and the two side drive sprockets in the power transmission path to ensure smooth power transmission.

[0050] A single drive motor 220 synchronously drives the sprocket assemblies 240 on both sides via a universal joint transmission assembly 230. This allows the chains on both sides of the feeding carriage 250 to pull it simultaneously, ensuring balanced force and synchronized speed on both sides. This avoids problems such as deviation, jamming, or tilting that can easily occur with single-sided drive. It is particularly suitable for the smooth transport of heavy long steel sections up to 12m in length and weighing over 1 ton, ensuring the stability of the workpiece 150 during transport. Only one drive motor 220 is needed to achieve synchronous dual-sided drive of the feeding carriage 250. Compared to a solution requiring two motors to drive each side separately, this saves one drive motor 220 and its associated driver, reducing equipment manufacturing costs and the complexity of the control system. Furthermore, there is no need for synchronized speed control of the two motors, simplifying the control logic and increasing system reliability.

[0051] The feeding rack 120 includes multiple independently set sub-frames. Each sub-frame is rotatably set on the inlet and outlet side of the housing 100. Each sub-frame can be independently flipped and folded into the housing 100 during transportation. During operation, each sub-frame is independently flipped downwards until it is flush with the bottom surface of the housing 100.

[0052] The loading rack 120 adopts a segmented modular design, consisting of multiple independently set sub-frames. Each sub-frame is rotatably installed in its corresponding mounting position on the inlet / outlet side of the housing 100. Each sub-frame can be independently flipped without interfering with others. During transportation, each sub-frame independently flips upward and folds to the side of the housing 100, forming a stowed state. The overall transport volume is small, meeting road transport clearance requirements. Upon arrival at the construction site, operators or the control system can selectively flip the sub-frames downward and unfold them until they are flush with the bottom surface of the housing 100. After unfolding, the sub-frames are assembled to form a loading platform for the material delivery vehicle 250 to drive out and perform loading and unloading operations.

[0053] Because each sub-frame flips independently, the size and weight of each sub-frame are significantly smaller than the integral feeding rack 120, resulting in a significant reduction in the driving torque required to flip a single sub-frame. Each sub-frame can be independently driven to flip using its own drive element (such as a cylinder, hydraulic cylinder, or motor), or it can be manually flipped by an operator, offering flexible usage. By disassembling the integral feeding rack 120 into multiple independent sub-frames, the size and weight of each sub-frame are greatly reduced, significantly lowering the torque required to flip. Whether driven by cylinders, hydraulic cylinders, or manually, it is more convenient and labor-saving, reducing the selection requirements and energy consumption of drive elements. The size of each sub-frame is much smaller than that of the integral feeding rack 120, eliminating the need for large bending and welding equipment during manufacturing, and making it easier to ensure processing accuracy. During transportation, each sub-frame is independently folded to the side of the box. Compared to the integral feeding rack 120, which requires flipping or disassembling as a whole during transportation, the modular structure of this invention facilitates loading and securing, reducing packaging and transportation costs.

[0054] The loading unit also includes multiple drive cylinders 160, each drive cylinder 160 is fixedly disposed inside the housing 100 and located above the feeding carriage 250, and each drive cylinder 160 is arranged at intervals along the conveying direction of the feeding carriage 250; when the piston rod of each drive cylinder 160 extends downward, it presses against the upper surface of the workpiece 150 to press and position the workpiece 150 on the feeding carriage 250; at least some of the piston rods of the drive cylinders 160 push the workpiece 150 along the conveying direction of the feeding carriage 250 to push the workpiece 150 to the processing position.

[0055] The loading unit is equipped with multiple drive cylinders 160, each fixedly installed inside the housing 100 and above the feeding carriage 250, arranged at intervals along the conveying direction of the feeding carriage 250, for horizontally pushing the workpiece 150 on the feeding carriage 250. When the workpiece 150 is pushed to the precise processing position, the control system controls the piston rod of each drive cylinder 160 to remain extended and continuously apply horizontal thrust to ensure that the workpiece 150 does not deviate horizontally during processing.

[0056] By driving the cylinder 160 to apply a thrust to the workpiece 150 in the horizontal direction, the workpiece 150 is precisely pushed to the preset processing position, avoiding the processing position deviation caused by the placement deviation of the workpiece 150, and ensuring the precise alignment of the cutting head and the part of the workpiece 150 to be processed.

[0057] Multiple drive cylinders 160 are arranged at intervals along the conveying direction of the feeding carriage 250. For a steel workpiece 150 with a length of up to 12m, multiple cylinders can push it in coordination from different positions in the horizontal direction. This avoids the problem of pushing the long material with a single point of force, which may cause the workpiece 150 to be too long or the friction to be uneven, resulting in skewed or stuck pushing. This ensures the stability of the pushing process of the long steel workpiece 150.

[0058] The processing unit 140 includes a cantilevered steel profile laser cutting machine, a laser, a chiller, an air compressor, a voltage stabilizer, and an electrical control cabinet; the laser, chiller, air compressor, voltage stabilizer, and electrical control cabinet are all located within the processing space of the housing 100; The cantilevered steel section laser cutting machine is set at one end of the processing space along the length direction. The laser is set at the front end of the cantilevered steel section laser cutting machine. The chiller, air compressor, voltage stabilizer and electrical control cabinet are set on the same side of the cantilevered steel section laser cutting machine. The cantilevered steel section laser cutting machine, laser, chiller, air compressor, voltage stabilizer and electrical control cabinet are arranged compactly in the processing space so as to leave a channel for the feeding carriage 250 to transport the workpiece 150 along the length direction of the shell 100 in the processing space.

[0059] The processing unit 140 uses a cantilevered steel section laser cutting machine as the core processing equipment, and is equipped with auxiliary equipment such as laser, chiller, air compressor, voltage stabilizer and electrical control cabinet. All equipment is integrated into the processing space of the housing 100.

[0060] The cantilevered steel section laser cutting machine is positioned at one end of the processing space along the length of the housing 100, with its cantilever beam extending along the width of the housing 100, providing open space for the workpiece 150 to enter and exit the cutting area. The laser is located at the front end of the cantilevered steel section laser cutting machine, generating a high-energy-density laser beam, which is transmitted to the cutting head via an optical path system. A chiller connected to the laser provides circulating water cooling for the laser and cutting head, removing the large amount of heat generated during laser operation and ensuring stable operation within a constant temperature range. An air compressor provides auxiliary gas (such as nitrogen, oxygen, or compressed air) for the cutting process, blowing molten metal out of the kerf to ensure the quality of the cut surface. A voltage regulator connects the external power supply to each electrical device, stabilizing the input voltage and preventing voltage fluctuations at the construction site from damaging the laser, control system, and drive system. The electrical control cabinet integrates a PLC controller, servo driver, relays, and other electrical components to receive processing commands and control the coordinated operation of various devices.

[0061] All of the above-mentioned auxiliary equipment are arranged on the same side of the cantilevered steel laser cutting machine, forming a compact arrangement with the cutting machine body. They are concentrated on one side of the shell 100 in the processing space, thereby forming a through conveying channel on the other side of the shell 100 in the length direction, allowing the feeding trolley 250 to carry the workpiece 150 and move back and forth in the processing space along the length direction, sending the workpiece 150 into and out of the cutting area.

[0062] During operation, the electrical control cabinet receives externally input processing instructions (including 3D model data), and the control system automatically plans the cutting trajectory and generates a processing program. The feeding trolley 250 carries the steel section to be processed and moves along the conveyor channel to the cutting area. After locking into position, the laser generates a laser beam, which is focused onto the surface of the workpiece 150 by the cutting head. The cantilever laser cutting machine drives the cutting head to move along the X, Y, and Z axes, and drives the A and B axes to swing, performing cutting, hole cutting, weld hole opening, beveling, marking, and other processing operations on the steel section according to the preset cutting trajectory. During processing, a chiller continuously cools the laser, an air compressor continuously provides auxiliary gas, and a voltage regulator ensures stable voltage. All auxiliary equipment works in conjunction with the cutting machine until the processing is completed.

[0063] This invention places the laser at the front end of a cantilevered steel section laser cutting machine, and places the chiller, air compressor, voltage stabilizer, and electrical control cabinet on the same side of the cutting machine. All auxiliary equipment is centrally arranged around the cutting machine, making full use of the limited space inside the container (3500mm wide × 16000mm long). While ensuring the normal operation and maintenance space of each piece of equipment, it achieves a high degree of integration of 140 sets of processing unit equipment, enabling the "mobile factory" concept to be realized in the field of heavy-duty steel section processing.

[0064] All auxiliary equipment is centrally arranged on the same side of the cutting machine, so that the other side of the housing 100 along its length forms a through conveying channel. The feeding trolley 250 can send steel workpieces 150 up to 12m in length straight into the cutting area from the inlet / outlet side and send them out from the other side along this channel. This avoids the problem of workpieces 150 needing to detour or be clamped multiple times due to equipment layout blocking the conveying path, and realizes straight loading and unloading of "side in and side out", which greatly improves the conveying efficiency of heavy long workpieces 150.

[0065] Reference Figures 1 to 3 The container unit includes a shell 100, and the shell 100 has a processing space inside. In this embodiment, the shell 100 adopts a standard shipping container with external dimensions of 3500mm (width) × 3500mm (height) × 16000mm (length), which facilitates long-distance transportation by road, rail or sea.

[0066] The processing unit 140 is located within the processing space and is used to perform laser cutting on the workpiece 150. The processing unit 140 includes a cantilevered steel section laser cutting machine, a laser, a chiller, an air compressor, a voltage stabilizer, and an electrical control cabinet.

[0067] The cantilevered steel section laser cutting machine is located at one end of the processing space along its length (i.e., the end furthest from the material inlet / outlet side), and includes a support column, a cantilever beam, a cutting head, a drive mechanism, and a swing mechanism. The support column is fixed to the bottom wall of the housing 100; one end of the cantilever beam is fixedly connected to the upper end of the support column, and the other end extends horizontally into the processing space along the width of the housing 100; the cutting head is mounted on the cantilever beam and can move along the length of the cantilever beam; the drive mechanism is connected to the cutting head and is used to drive the cutting head to move in the X, Y, and Z axis directions; the swing mechanism is connected to the cutting head and is used to drive the cutting head to swing around the A and B axes, with swing angles of ±90° for both the A and B axes.

[0068] The laser is positioned at the front end of the cantilever steel laser cutting machine (i.e., the end closest to the material inlet / outlet side) to generate a high-energy-density laser beam, which is then transmitted to the cutting head via an optical path system. The chiller, air compressor, voltage stabilizer, and electrical control cabinet are all located on the same side of the cantilever steel laser cutting machine (e.g., along the width of the housing 100), arranged compactly with the cantilever steel laser cutting machine within the processing space. This creates a channel along the length of the housing 100 within the processing space for the feeding trolley 250 to transport the workpiece 150; the width of the channel is not less than the maximum width of the workpiece 150 (not less than 600 mm in this embodiment).

[0069] The loading unit includes a loading rack 120 and a feeding cart 250. The loading rack 120 is rotatably mounted on the inlet / outlet side of the housing 100. During transport, the loading rack 120 is folded upwards against the outer wall of the inlet / outlet side of the housing 100, and during operation, it is flipped downwards until it is flush with the bottom surface of the housing 100. The feeding cart 250 is used to transport the workpiece 150 on the loading rack 120 back and forth within the processing space.

[0070] like Figure 1 As shown, in this embodiment, the feeding rack 120 includes multiple independently arranged sub-frames. Each sub-frame is rotatably arranged on the inlet / outlet side of the housing 100. Each sub-frame can be independently flipped and folded independently within the housing 100 during transportation. During operation, each sub-frame is independently flipped downwards until it is flush with the bottom surface of the housing 100. The sub-frames are spaced apart along the width direction of the housing 100 (i.e., the length direction of the inlet / outlet side). The width of each sub-frame is 800mm~1200mm, and the number is 4~6. Each sub-frame is hinged to the bottom of the inlet / outlet side of the housing 100 through an independent hinge mechanism. Each sub-frame is equipped with an independent driving element (such as a cylinder or hydraulic cylinder) to drive the flipping, or it can be manually flipped by the operator.

[0071] The feeding unit also includes support legs 110, which are detachably mounted on the inlet / outlet side of the housing 100. The support legs 110 extend along the conveying direction of the feeding trolley 250, and their upper surfaces form support tracks for the rollers 260 at the bottom of the feeding trolley 250 to roll. Multiple support legs 110 are provided, symmetrically arranged at both ends and the middle of the inlet / outlet side of the housing 100 along its width direction (i.e., the length direction of the inlet / outlet side). Each support leg 110 has an independent adjusting seat 210 at its bottom, which independently adjusts the support height of the corresponding support leg 110 relative to the ground. When each adjusting seat 210 is adjusted independently, the height of the upper surface of the support leg 110 changes accordingly to keep the upper surfaces of all support legs 110 at the same horizontal plane. In this embodiment, the adjusting seat 210 uses a screw adjustment mechanism.

[0072] like Figure 1 and Figure 4 As shown, the loading rack 120 is provided with a clearance portion 130, which is a notch opened at the position of the support leg 110 on the loading rack 120. The notch extends along the flipping direction of the loading rack 120 (that is, along the width direction of the housing 100). The support leg 110 passes through the notch, so that when the loading rack 120 is flipped down to be flush with the bottom surface of the housing 100, the support leg 110 is accommodated in the notch, so as to avoid interference between the loading rack 120 and the support leg 110.

[0073] like Figure 3 and Figure 6 As shown, the bottom of the feeding trolley 250 is equipped with rollers 260, and at least two rows of rollers 260 are arranged along the width direction (i.e., the conveying direction) of the housing 100. The upper part of the feeding trolley 250 is equipped with a steel bracket, the height of which is 800mm, for supporting the steel workpiece 150. When the feeding trolley 250 is loading, the bottom rollers 260 extend outward from the bottom surface of the housing 100 and roll onto the support rails of the support legs 110. The support legs 110 provide support for the feeding trolley 250 and the workpiece 150 it carries.

[0074] The bottom of the feeding trolley 250 is driven by a sprocket drive mechanism. The sprocket drive mechanism includes a drive motor 220, a universal joint drive assembly 230, and two sets of sprocket assemblies 240. The two sets of sprocket assemblies 240 are respectively located on both sides of the bottom of the feeding trolley 250 along the width direction of the housing 100 (i.e., the left and right sides of the bottom of the feeding trolley 250), and the length direction of each set of sprocket assemblies 240 is parallel to the width direction of the housing 100 (i.e., extending along the width direction of the housing 100). Each set of sprocket assemblies 240 includes a driving sprocket, a driven sprocket, and a chain tensioned between the driving and driven sprockets. The chain is fixedly connected to the feeding trolley 250. The output end of the drive motor 220 is connected to the driving sprockets on both sides via the universal joint drive assembly 230. After the drive motor 220 starts, it synchronously distributes power to the drive sprockets on both sides through the universal joint drive assembly 230. The drive sprockets on both sides rotate synchronously and drive their respective chains to run. The chains on both sides simultaneously pull the feed carriage 250 to move along the conveying direction (i.e., the length direction of the housing 100). The universal joint drive assembly 230 includes a universal joint and a drive shaft, which can compensate for the coaxiality deviation and angular deviation between the output shaft of the drive motor 220 and the rotating shafts of the drive sprockets on both sides.

[0075] The feeding unit also includes a positioning component. The positioning component includes a first position sensor 180 and a second position sensor 190.

[0076] The first position sensor 180 is located within the processing space (near the processing start position, i.e., the first predetermined stop position reached by the feed carriage 250 carrying the workpiece 150 after entering the processing space) and is used to detect whether the feed carriage 250 has reached the processing start position. The processing unit 140 only begins processing when the first position sensor 180 detects that the feed carriage 250 has arrived at its position.

[0077] The second position sensor 190 is located on the inlet / outlet side of the housing 100 (i.e., the loading position, located outside the inlet / outlet side of the housing 100 or at the inlet / outlet port) to detect whether the feeding trolley 250 has reached the loading position. The loading rack 120 is only allowed to perform the loading action when the second position sensor 190 detects that the feeding trolley 250 has arrived. Specifically, after the second position sensor 190 outputs a positioning signal, the control system allows the operator to perform loading and unloading operations. The external conveyor belt connects to the feeding trolley 250, and a crane is used to lift the workpiece 150 to be processed onto the conveyor belt, which then transports it to the feeding trolley 250; or the feeding trolley 250 transports the processed workpiece 150 to the conveyor belt, and the crane then lifts it off the conveyor belt. This interlocking mechanism prevents the loading and unloading equipment from malfunctioning and colliding with the feeding trolley 250 if it has not fully retracted.

[0078] The positioning assembly also includes a locking cylinder 170. A mating part 200 is provided at the bottom of the feeding carriage 250 corresponding to the position of the locking cylinder 170. The mating part 200 is either a positioning hole formed at the bottom of the feeding carriage 250 or a positioning block provided at the bottom of the feeding carriage 250. After the feeding carriage 250 reaches the processing position, the piston rod of the locking cylinder 170 extends and inserts into the positioning hole or abuts against the positioning block, locking the feeding carriage 250 in the processing position.

[0079] The loading unit also includes multiple drive cylinders 160, each drive cylinder 160 being fixedly disposed within the housing 100 and located above the feeding carriage 250, with the drive cylinders 160 spaced apart along the conveying direction of the feeding carriage 250. The piston rod of each drive cylinder 160 extends along the conveying direction of the feeding carriage 250, with its end abutting against the end or side of the workpiece 150, for pushing the workpiece 150 on the feeding carriage 250 horizontally to the processing position. Once the workpiece 150 is pushed to the precise processing position, the control system controls the piston rods of each drive cylinder 160 to remain extended and continuously apply horizontal thrust, ensuring that the workpiece 150 does not deviate horizontally during processing.

[0080] A processing method according to a second aspect of the present invention includes an intelligent mobile processing center according to a first aspect embodiment, wherein the loading unit includes a support leg 110 and a positioning component, and includes the following steps: Step S1: Start the equipment and start each component of the processing unit 140 to put the processing unit 140 into a ready-to-process state; Step S2: Input processing instructions, and input the processing content and processing parameters through the control system; Step S3: Loading. Flip the loading rack 120 downwards until it is flush with the bottom surface of the housing 100. The feeding carriage 250 drives out from the processing space along the support leg 110 to the loading rack 120. Then, place the workpiece 150 to be processed on the feeding carriage 250. Step S4: Feeding and positioning. The feeding carriage 250 carries the workpiece 150 along the support leg 110 and the processing space to the processing position. The positioning component detects whether the feeding carriage 250 has reached the processing position. When the feeding carriage 250 is detected to be in place, the feeding carriage 250 stops and locks. Step S5: Processing, the processing unit 140 performs processing operations on the workpiece 150 according to the processing instructions; Step S6: Unloading. After the processing is completed, the feeding car 250 is unlocked and carries the processed workpiece 150 out of the processing space.

[0081] In this embodiment, step S1: Equipment startup. Start all components of the processing unit 140, including the cantilever steel laser cutting machine, laser, chiller, air compressor, voltage stabilizer, and electrical control cabinet, to put the processing unit 140 into a ready-to-process state. Check whether the operating status of each device is normal, and whether the air pressure, water pressure, and voltage reach the set values.

[0082] Step S2: Input machining instructions. Input the machining content and parameters through the computer interface of the control system (integrated in the electrical control cabinet) or a USB flash drive. In this step, the control system supports direct import of 3D models such as TEKLA. After import, it automatically plans the cutting trajectory and generates the machining program, eliminating the need for manual programming. Machining parameters include workpiece material (150mm), thickness, cutting speed, laser power, and auxiliary gas pressure.

[0083] Step S3: Loading. First, the loading rack 120 is flipped downwards until it is flush with the bottom surface of the housing 100. For the loading rack 120, which contains multiple sub-racks, the corresponding number of sub-racks are selectively unfolded according to the length of the workpiece 150 to be processed. For example, when processing short materials, only some sub-racks are unfolded, and when processing long materials, all sub-racks are unfolded. Then, the feeding trolley 250 drives out from the processing space along the support legs 110 to the loading rack 120. It connects with the feeding trolley 250 via an external conveyor belt. The workpiece 150 to be processed is hoisted onto the conveyor belt and transported to the feeding trolley 250 by the conveyor belt, or the workpiece 150 to be processed is placed directly on the feeding trolley 250. This method is particularly suitable for steel body components with a width of 100mm~600mm, a height of 100mm~500mm, a length of up to 12000mm, and a weight of up to 1 ton or more.

[0084] Step S4: Feeding and Positioning. The feeding carriage 250, carrying the workpiece 150, moves along the support legs 110 and the machining space to the machining position. The positioning assembly performs graded positioning of the feeding carriage 250: Through the complete automated process design of steps S1 to S6, a continuous flow operation mode is formed from equipment startup, command input, automatic feeding, automatic feeding and positioning, automatic processing to automatic unloading. It realizes full automation of feeding, conveying, positioning, processing and unloading, replacing the manual marking and manual operation of equipment in traditional mobile factories, which greatly improves processing efficiency and reduces labor costs. The feeding trolley 250 drives out along the support leg 110 to the loading rack 120 to receive the workpiece 150, and then moves along the support leg 110 and the processing space to the processing position. The support leg 110 provides an extended travel track for the extension and retraction of the feeding trolley 250, and at the same time provides reliable support for the feeding trolley 250 and the heavy workpiece 150 it carries during the feeding process, ensuring the smooth operation and safety of the 12m long and 1 ton heavy steel main component during the loading and unloading process.

[0085] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
