Description

Technical Field

[0001] This invention relates to the field of building waterproofing construction equipment technology, specifically a mechanical structure and its control method that can be used for laying waterproof membrane rolls. Background Technology

[0002] Waterproof membranes, as key waterproofing materials in building engineering to prevent rainwater and groundwater seepage, are widely used in building walls, roofs, tunnels, highways, landfills, and underground pipe corridors, serving as the core guarantee for a leak-free connection between the foundation and the building. According to the industry standard GB55030-2022, "General Specification for Waterproofing of Building and Municipal Engineering," the laying of waterproof membranes must meet two core requirements: first, the bond strength between the membrane and the substrate must exceed 0.25 MPa; second, the membrane should be laid flat and straight, without bulging, gaps, or curling edges, otherwise, it is easy to form continuous seepage paths, leading to leakage problems and seriously affecting the service life and quality of the building. Currently, the laying of waterproof membranes (especially large-area hot-melt method) mainly relies on traditional manual operation. The hot-melt construction process requires the collaboration of several experienced workers: using equipment such as spray guns and blowtorches to heat the underside of the membrane and the surface of the substrate, melting the asphalt on the membrane surface, rolling it while heating, and then compacting it with rollers.

[0003] Traditional manual installation methods have significant technical defects and industry pain points. In terms of quality, manual operation is prone to quality fluctuations due to individual differences and fatigue. While roll material seams require strict alignment and ensured overlap width, measurement errors or weak adhesion can easily lead to high rates of hollow areas, gaping seams, or even separation. When two people work together, inconsistent movements or varying tension can cause the roll material to bend, bulge, or even break, making it difficult to consistently meet industry standards such as "no bulging, gaping, or curling edges" and "bonding strength > 0.25MPa." Regarding safety... Waterproof membranes (such as SBS modified bitumen membranes) are mainly composed of bitumen, with an ignition point of approximately 260°C. When heated to high temperatures, they are highly flammable and spread rapidly when exposed to an open flame. During construction, if equipment such as spray guns or blowtorches experiences gas leaks, abnormal pressure, or incorrect flame angles, it can easily cause a fire. Furthermore, open flame application can easily lead to burns and scalds for workers, and the toxic and harmful gases released during the heating process can seriously endanger the health of construction workers. In terms of efficiency, traditional construction relies on manual labor, with skilled workers only able to lay an average area of ​​100-200 square meters per day. 2 The current methods are inefficient, and labor costs account for a large proportion of the total project cost. Due to the high labor intensity and poor working environment of waterproofing construction, there is a shortage of young and middle-aged workers, resulting in a shortage of skilled workers and a serious aging population, which further exacerbates the problems of high construction costs and long construction periods. Among the existing technologies, some semi-automatic equipment lacks a precise bubble discharge mechanism, the hollow rate is still relatively high, and the stability of remote control is insufficient, making it difficult to adapt to complex construction environments.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a mechanical structure that can be used for laying waterproof membranes in order to overcome the shortcomings in current practical applications. Summary of the Invention

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0050] Please see Figures 1-11 This invention provides a mechanical structure and its control method for laying waterproof membrane rolls. It achieves full automation of the membrane laying process through mechatronics technology. The core components include the coordinated operation of the membrane conveying, rewinding, leveling, hot-melt compaction, travel, and electrical control systems. Specifically, it includes the following:

[0051] Example 1: Overall structure and full-process working mechanism;

[0052] This embodiment describes in detail the complete composition of the device, the connection relationship of its components, and the overall working logic, ensuring that those skilled in the art can assemble and operate the device based on this.

[0053] 1. Overall composition of the device;

[0054] The device comprises six core mechanisms and an electronic control system: a roll rewinding mechanism, a roll conveying mechanism, a roll segmentation mechanism, a dual-mode compaction mechanism, a side pressure roller angle adjustment mechanism, a flame-spraying and heat-sealing mechanism, and an electronic control system based on the STM32F407 chip. The connection relationships of each component are as follows:

[0055] The coil rewinding mechanism is supported by aluminum profile 102 of the vehicle body and fixed by bolts and mounting brackets 401 to achieve coil rewinding and unwinding. A DC motor II 402 is connected to a rewinding rod 403. One end of the coil is placed between the two rods via two unpowered rollers 404. The rotation of the DC motor II 402 achieves stable rewinding of the coil, with its speed controlled and adjusted by an STM32F407 chip. This system uses the STM32F407's USART2 (PA2, PA3) to connect to a Bluetooth module. PB3 and PB4 control a 42-stepper motor 601, PA6 and PA7 control a 57-stepper motor II 501, and PG4 and PG5 control the DC motor II 402. The logic section is powered by 3.3V, while the motor drive requires an external 12V~24V power supply.

[0056] The roll material conveying mechanism includes a 57 stepper motor II 501, a worm gear I 502, a worm I 503, a transmission gear 505, and an anilox roller 504. The worm gear I 502 is meshed with the worm I 503, the worm I is connected to the 57 stepper motor II 501, and the worm gear I 502 is connected to the anilox roller 504 through a set screw, simultaneously driving the rewinding rod 403 to achieve steady-speed unwinding. The transmission gear 505 is nested at the other end of the anilox roller 504, stably transmitting power to the other anilox roller 504, causing the two anilox rollers to rotate in opposite directions to achieve steady-speed unwinding. The support roller 103 and the cutting roller 106 work together to form a continuous roll material conveying channel, assisting in the smooth transition of the roll material. The meter counter 1001 is in contact with the anilox roller 504 and has the same linear speed as the anilox roller 504, recording the roll material laying length.

[0057] The roll material cutting mechanism includes a 42-stepper motor 601, a blade holder 602, a trapezoidal lead screw 603 (right-handed, 5mm lead), a lead screw slide 604, and a blade 605 (high carbon steel T10A, HRC58-60). The blade 605 is fixed to the aluminum blade holder 602 with screws, and the blade holder 602 is fixed to the lead screw slide 604. The 42-stepper motor 601 drives the trapezoidal lead screw 603, which in turn moves the lead screw slide 604 and the blade 605 laterally to achieve roll material cutting. The cutting roller 106 below the lead screw provides support during roll material cutting and assists in the smooth cutting of the roll material.

[0058] Dual-mode compaction mechanism: The central pressure roller 105 and side pressure rollers I 101 and II 104 are mounted on the bottom frame of the vehicle body 102 via the main roller base 701, the side connector 702 of the main roller, and the connecting rod 808. The central pressure roller 105 is a driven steel roller with its axis perpendicular to the laying direction. The side pressure rollers I 101 and II 104 are textured coated rollers, symmetrically distributed on both sides of the central pressure roller 105, with an inclination angle adjustable from 0° to 180° (optimal 30°), and the pressure is slightly less than that of the central pressure roller. Roller 105; wherein, stepper motor I 204 drives the connecting shaft, the connecting shaft drives worm II 801 (axial module of 2, number of teeth of 27) to rotate, and through the transmission relationship, worm wheel II 809 rotates. The bevel gears on both sides (bevel gear I 803 and bevel gear II 806, both with 2 modules and 30 teeth, and a transmission ratio of 1:1) drive the connecting rod 808 to rotate through tangential transmission, thereby adjusting the angle of the side pressure roller. The gears and worm wheel are limited by snap rings on the outside and connected by flat keys on the inside.

[0059] 302 rubber tire with pulleys: Both front and rear wheels are made of wear-resistant rubber and are driven by DC motors. They are combined with a differential steering mechanism (the motor is connected to a 5M18 tooth synchronous belt pulley, which is connected to a 5M72 tooth synchronous belt pulley on the rubber tire with pulleys. The center distance between the pulleys is 95mm, achieving a 4:1 transmission. There is a similar mechanism on both the left and right rear wheels. When the left and right DC motors rotate at different speeds, the machine can turn. When the left and right motors rotate at the same speed but in different directions, the machine rotates with the midpoint between the rear wheels as the center, and the minimum turning radius is 1m) to achieve the movement and steering of the equipment.

[0060] The flame-throwing device is connected to the gas cylinder 903 via a solenoid valve 902 group, and the nozzle 901 is connected to the outlet of the solenoid valve via a heat-insulated pipeline.

[0061] Electrical control system: The main control unit is an STM32F407 chip, which is connected to a Bluetooth 5.0 module (control distance ≤50m) via a UART interface, a DC motor drive unit (connected to the walking motor and the roll rewinding mechanism), a 57 stepper motor drive unit (connected to the roll conveying mechanism and the side pressure roller angle adjustment mechanism), a 42 stepper motor drive unit (connected to the cutting mechanism), and a gas valve control unit (connected to a group of 902 solenoid valves).

[0062] 2. The entire process steps are as follows:

[0063] Step 1: Device initialization;

[0064] The STM32F407 chip initiates a self-test by remotely sending an initialization command via Bluetooth 5.0: confirming that the rewind rod 403 is in the zero position, there are no foreign objects on the surface of the anilox roller 505, the side roller 104 is locked at 30°, and there is no leakage in the gas valve control unit; at the same time, the roll loading is completed, and the center line of the roll is aligned with the longitudinal axis of the equipment when adjusting the position of the roll.

[0065] Step 2: Roll material feeding;

[0066] Stepper motor II 501 starts and drives the anilox roller 504 to rotate through the worm gear transmission assembly (transmission ratio 40:1). The anilox roller 504 moves the roll material through friction and extrusion. During the conveying process, the support roller 103 and the cutting roller 106 provide support for the roll material and form a path.

[0067] The meter counter 1001 is connected to the shaft of the anilox roller and rotates at the same linear speed as the anilox roller through friction, thus recording the laying length.

[0068] Step 3: Roll material cutting, stress relief, rewinding, and heated laying;

[0069] When the roll material is fed to the predetermined length, a manual Bluetooth signal is sent to the STM32F407 chip. The STM32F407 chip sends a command to the 42-stepper motor drive unit. The 42-stepper motor 601 drives the trapezoidal lead screw 603, which in turn moves the blade 605 laterally along the lead screw slide 604 to complete the cutting according to the preset size and release stress. After stress release, a section of the roll material is fed into the rewinding rod 403 through the non-powered roller 404, and the DC motor II 402 is started to complete the rewinding. After the rewinding is completed, the roll material support frame 404 and the side support frame 405 are removed, and the roll material can be taken out from the side and re-laid. At the same time, heating is carried out. The nozzle 901 of the propane / oxygen mixed burner (connected to the solenoid valve 902 group through the heat insulation pipeline) sprays flames onto the base layer below the cut. The gas valve control unit adjusts the gas flow rate of the gas tank 903 to keep the heating temperature of the base layer surface at 200-210℃ (the asphalt layer on the lower surface of the roll material melts and shines).

[0070] Step 4: Dual-mode compaction and air bubble removal;

[0071] The dual-mode refers to full-adhesion laying and semi-adhesion laying. Full-adhesion laying refers to compacted laying, while semi-adhesion laying refers to compaction on both sides and loose laying in the middle. The full-adhesion laying process is as follows: The heated roll material is transported to the compaction station: The central pressure roller 105 first rolls vertically, and the roll material is initially bonded to the base layer through the 30 kg central pressure roller 105; Simultaneously, the side pressure roller I 101 and the side pressure roller II 104 roll at a 30° angle. Their tangential velocity component vτ=vcosθ (v is the rolling speed of the roller) and normal component vσ=vsinθ work together to push the air bubbles between the roll material and the base layer to the sides. For semi-adhesion laying, it is only necessary to close the central flame-spraying pipe with the solenoid valve 902.

[0072] Step 5: Walking and continuous operation;

[0073] The DC motor controls the rotation speed of the rubber tire 302 pulley via the synchronous belt 303, so that the equipment travel speed matches the rhythm of roll material conveying and compaction (e.g., laying speed 20m² / h). If overlapping is required, the differential steering mechanism adjusts the speed difference between the left and right tires, and controls the equipment to automatically retract and turn to complete the overlapping.

[0074] Step 6: Stop and reset;

[0075] After the corresponding laying process is completed, a stop command is sent remotely, and the STM32F407 chip controls each module to stop in sequence: the lead screw cutting mechanism is reset to the initial position, the gas valve is closed, the main / side rollers stop rotating, and the equipment is parked after traveling to the end point, waiting for the next operation.

[0076] Example 2: Adaptation and optimization for underground utility tunnel scenarios;

[0077] This embodiment is designed for underground utility tunnels (narrow and with many corners). It optimizes the walking and compaction mechanism based on embodiment 1, while the rest of the structure and workflow are the same as in embodiment 1.

[0078] The walking mechanism has been optimized: the 302 wheeled rubber tires have been replaced with tracked walking components, and the differential steering mechanism has been upgraded to multi-axis cooperative steering. The corner radius (turning radius > 1m) is calculated in real time using the STM32F407 chip to adapt to the narrow space of the pipe gallery.

[0079] Dual-mode compaction mechanism adjustment: The inclination angle of the side pressure roller can be remotely adjusted via the electronic control system (0°-180° stepless adjustment). When constructing near the side wall of the pipe gallery, the inclination angle can be adjusted to 45° to reduce lateral footprint and avoid interference with the side wall of the pipe gallery.

[0080] Heating module adaptation: Due to poor ventilation in the pipe gallery, nozzle 901 is equipped with a flue gas collection channel, which, together with the gas valve control unit, reduces the flame temperature to 160-170℃, thereby reducing the release of toxic gases.

[0081] Example 3: Cooperative control logic of the electronic control system;

[0082] This embodiment details the signal interaction process of each module in the electronic control system to ensure control stability; the rest of the structure is the same as in Embodiment 1.

[0083] Signal transmission link:

[0084] Remote commands (start / stop / parameter adjustment) are transmitted to the STM32F407 chip via a Bluetooth 5.0 module (BLE Low Power Mode). After parsing, the chip generates PWM signals and sends them to each driver unit. The Bluetooth 5.0 module uses frequency hopping technology with a channel switching interval of 10ms, and CRC check ensures that the command transmission accuracy is ≥99.9%.

[0085] Multi-motor coordination timing:

[0086] The start-up time difference between the roll material conveying motor (worm gear drive) and the traveling motor is reduced, ensuring that the conveying speed matches the traveling speed;

[0087] Before the cutting motor starts, the STM32F407 chip sends a pause signal to the conveyor motor. After the cutting is completed (3s), the conveyor motor is restarted with a delay to avoid the roll material from shifting during cutting.

[0088] Fault self-diagnosis:

[0089] The chip monitors motor current, gas pressure, and Bluetooth connection status in real time. If an abnormality is detected (such as motor stall current ≥ 1.5 times rated current), the protection mechanism is immediately triggered: the relevant module is stopped from running, and a fault code (such as "E01" representing motor overload) is fed back via Bluetooth, waiting for manual troubleshooting.

[0090] The above embodiments describe in detail the core structure, workflow, and scenario adaptation optimization of the present invention. Those skilled in the art can reproduce the technical solution of the present invention based on the above description and the accompanying drawings. It should be noted that the above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. All equivalent modifications based on the structure, parameters, and principles of the present invention fall within the scope of protection of the present invention.

[0091] It should be noted that, in this invention, unless otherwise explicitly specified and limited, the terms "sliding," "rotating," "fixed," and "equipped" should be interpreted broadly. For example, they can refer to welded connections, bolted connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0092] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
