Description

Technical Field

[0001] The utility model belongs to the technical field of waterproof coiled material paving construction, and particularly relates to a temperature-controlled waterproof coiled material paving machine. Background Technique

[0002] The polymer modified bitumen waterproof coiled material is a material supplied in rolls and is composed of a waterproof material and a reinforcing material. Its main purpose is to provide a durable waterproof layer in a specific area of a building to prevent water penetration. Usually, the coiled material is paved by the hot melt method. In traditional paving, workers need to hold a spray gun to heat the coiled material by hand, and fix the coiled material by rolling to position and pave it. Such a paving method consumes a large amount of physical strength, has low construction efficiency, and the waterproof coiled material is prone to unevenness such as wrinkles, warping, and twisting, thus affecting the paving effect of the waterproof material and being not conducive to large-area paving work. In addition, it is not easy for traditional manual spray guns to control the combustion temperature of the spray gun. If the temperature is too low, the waterproof coiled material is insufficiently heated and has a poor adhesion to the base layer, and it is easy to have air pockets and bulges; if the temperature is too high, the coiled material is easily burned through and melted, directly affecting the waterproof performance of the coiled material. Moreover, most labor teams carry out paving only based on construction experience, and there are potential quality hazards in paving. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0024] Combined with Figures 1 to 3 As shown, an embodiment of the present utility model provides a temperature-controlled waterproof coiled material paving machine, which includes a T-shaped hand-pushing frame body 4, a hot-melt assembly 2, and a temperature control assembly. A bow-shaped frame 401 is fixedly connected to the lower end of the T-shaped hand-pushing frame body 4, and a rolling roller 1 for winding the waterproof coiled material is connected between the two ends of the bow-shaped frame 401. Specifically, the T-shaped hand-pushing frame body 4 serves as the main frame of the entire paving machine. The T-shaped hand-pushing frame body 4 not only provides a stable support structure but also facilitates the operator to push the machine for operation. At the lower end of the T-shaped hand-pushing frame body 4, a bow-shaped frame 401 is fixedly connected, and the rolling roller 1 is connected between the two ends of the bow-shaped frame 401 through a bearing or a similar mechanism. The rolling roller 1 is used to wind and compact the waterproof coiled material during the paving process to ensure that it is flat and wrinkle-free.

[0025] The hot-melt assembly 2 includes an inverted T-shaped air duct 202 assembled on the T-shaped hand-pushing frame body 4. The horizontal section of the inverted T-shaped air duct 202 is parallel and located in front of the upper part of the rolling roller 1. A plurality of flame nozzles 201 facing the lower front of the rolling roller 1 are communicatedly arranged on the horizontal section of the inverted T-shaped air duct 202, and the vertical section of the inverted T-shaped air duct 202 is connected to a gas tank 203. Specifically, the hot-melt assembly 2 is installed on the T-shaped hand-pushing frame body 4 and is used to perform hot-melt treatment on the waterproof coiled material so that it can be better adhered to the base layer. The hot-melt assembly 2 includes an inverted T-shaped air duct 202. The horizontal section of this air duct is parallel and located in front of the upper part of the rolling roller 1 to ensure that the flame can uniformly and effectively heat the coiled material. On the horizontal section of the inverted T-shaped air duct 202, a plurality of flame nozzles 201 are arranged. These flame nozzles 201 face the lower front of the rolling roller 1 and are used to spray flames to heat the coiled material. The vertical section of the inverted T-shaped air duct 202 is connected to the gas tank 203 to provide gas for the flame nozzles 201.

[0026] The temperature control component includes a single chip microcomputer 302, a temperature sensor 301 disposed at each flame nozzle 201, and a solenoid valve 303 disposed at the vertical section of the inverted T-shaped air guide pipe 202, and the temperature sensor 301 and the solenoid valve 303 are both electrically connected to the single chip microcomputer 302. Specifically, the temperature control component controls the temperature of the flame nozzle to ensure that the waterproof coiled material can be fully melted during the paving process and will not be damaged due to excessive temperature. The temperature control component includes a single chip microcomputer 302, a temperature sensor 301 and a solenoid valve 303. A temperature sensor 301 is disposed near each flame nozzle 201 for real-time monitoring of the temperature of the flame nozzle and transmitting the temperature signal to the single chip microcomputer 302. The single chip microcomputer 302 adjusts the amount of gas supplied from the gas tank 203 to the flame nozzle 201 by controlling the opening of the solenoid valve 303 according to the received temperature signal, thereby realizing precise control of the flame temperature.

[0027] When in use, the operator first wraps the waterproof coil around the rolling roller 1 and pushes the T-shaped hand push frame 4 to move. As the equipment moves, the flame nozzle 201 begins to spray flames to heat the coil. At this time, the temperature sensor 301 monitors the temperature of the flame nozzle in real time and transmits the temperature signal to the single-chip computer 302. The single-chip computer 302 adjusts the gas supply by controlling the opening of the solenoid valve 303 according to the preset temperature range and the received temperature signal, so that the flame temperature remains within a suitable range. At the same time, the rolling roller 1 rolls under the coil, compacts the heated coil and fixes it on the base layer to complete the paving work. The temperature-controlled waterproof coil paving machine of the utility model can realize the efficient and accurate paving of waterproof coils, which not only improves the construction efficiency, but also improves the waterproof effect and paving quality.

[0028] As a more preferred embodiment, Figure 1 and Figure 2 As shown, the temperature-controlled waterproof membrane paving machine also includes a downward pressing and fastening assembly 6, which includes an inverted Y-shaped wire tube 601 assembled on the T-shaped hand push frame 4, a traction line 6011 passed through the inverted Y-shaped wire tube 601, a ribbed rod assembly 605 connected between the bow frames 401, a transverse conduction rod 603 hinged on the ribbed rod assembly 605, a vertical conduction rod 602 hinged at one end of the transverse conduction rod 603, and a pressure rod assembly 604 fixed to the lower end of the vertical conduction rod 602, the pressure rod assembly 604 is connected to the non-rotating part of the rolling roller 1, and the other end of the transverse conduction rod 603 is connected to one end of the traction line 6011.

[0029] Specifically, the inverted Y-shaped wire tube 601 is assembled on the T-shaped hand push frame body 4, and its designed shape is convenient for guiding the direction of the traction wire and protecting it from external interference. The design of the inverted Y-shaped wire tube enables the traction wire to be introduced from both sides respectively and converge at the central position, providing convenience for subsequent transmission. The traction wire 6011 is threaded through the inverted Y-shaped wire tube 601 and is used to transmit the pulling force from the operation end. The traction wire can be made of high-strength and wear-resistant materials such as steel wire ropes or special fiber wires to ensure its stability and durability during use. The ribbed rod assembly 605 is connected between the bow frames 401 to provide a stable support structure for the entire downward pressing and fastening assembly. The design of the ribbed rod assembly 605 needs to ensure that it will not deform or break during the pressing process. The lateral conduction rod 603 is hinged on the ribbed rod assembly 605 and can swing within a certain angular range. One end of it is connected to the traction wire 6011, used to receive the power from the traction wire and transmit it to the vertical conduction rod 602. The vertical conduction rod 602 is hinged at the other end of the lateral conduction rod 603, converting the movement of the lateral conduction rod 603 into a movement in the vertical direction. The vertical conduction rod 602 can smoothly and steadily transmit force during the movement. The pressing rod assembly 604 is fixedly connected to the lower end of the vertical conduction rod 602 and directly acts on the non-rotating part of the rolling roller 1. When the vertical conduction rod 602 moves downward, the pressing rod assembly 604 will press the rolling roller 1 and the waterproof coiled material thereon, thereby enhancing the adhesion between the coiled material and the base layer.

[0030] During use, the operator can apply a pulling force to the traction wire 6011 through the operation end (such as a handle, button, etc.). The movement of the traction wire is guided by the inverted Y-shaped wire tube 601 to the lateral conduction rod 603, and then transmitted to the vertical conduction rod 602 through the lateral conduction rod 603. The downward movement of the vertical conduction rod 602 drives the pressing rod assembly 604 to press the rolling roller 1 and the waterproof coiled material thereon. At this time, while the rolling roller 1 continues to roll, it receives an additional pressure from the pressing rod assembly 604, making the waterproof coiled material fit more tightly on the base layer. Through the design of the downward pressing and fastening assembly 6, the temperature-controlled waterproof coiled material laying machine of the present utility model can more effectively ensure the flatness and adhesion of the waterproof coiled material during the laying process, further improving the construction quality and efficiency.

[0031] In an implementable manner, as Figure 1 shown, an adjusting handle 5 is hinged to the horizontal section of the T-shaped hand push frame body 4. The adjusting handle 5 is connected to the other end of the traction wire 6011, and the adjusting handle 5 can tension the traction wire 6011.

[0032] Specifically, the adjustment handle 5 is designed in an ergonomic handle shape for easy gripping and operation by the operator. The adjustment handle 5 is hinged on the horizontal section of the T-shaped hand-pushing frame body 4. This design is convenient for the operator to adjust at any time and does not affect the overall stability and mobility of the paving machine. The hinge point of the adjustment handle 5 should be designed with sufficient strength and stability to withstand the pulling force and torque during operation. When in use, the operator can change the relative position between the adjustment handle 5 and the T-shaped hand-pushing frame body 4 by squeezing the adjustment handle 5, and this action will directly affect the tension of the traction line 6011. When it is necessary to increase the tension, the operator squeezes the adjustment handle 5 tightly; conversely, when it is necessary to reduce the tension, the operation is in the opposite direction. The design of the adjustment handle 5 enables the operator to fine-tune the tension of the traction line 6011 at any time according to the actual situation and needs, which can not only ensure that the waterproof coiled material is subjected to uniform and stable pressure during paving, but also effectively avoid problems such as coiled material wrinkling and slipping caused by insufficient or excessive tension.

[0033] Preferably, a locking mechanism (such as screw locking, snap locking, etc.) can also be equipped inside the adjustment handle 5, which can fix the adjustment handle 5 in place after adjustment to prevent it from moving due to accidental contact during paving, thus ensuring the continuity and stability of the paving operation.

[0034] Preferably, as Figure 1 and Figure 2 shown, at positions near both ends of the rolling roller 1, the ribbed rod assembly 605 is symmetrically hinged with transverse transmission rods 603. One end of each transverse transmission rod 603 is hinged with a vertical transmission rod 602. The other end of each transverse transmission rod 603 is connected to one end of the traction line 6011, and the lower end of each vertical transmission rod 602 is fixedly connected to the pressure rod assembly 604. This symmetrical design can ensure that the waterproof coiled material can receive balanced pressure from both sides during the pressing process, avoiding deviation or inclination.

[0035] Preferably, as Figure 2 shown, at positions near both ends of the horizontal section of the T-shaped hand-pushing frame body 4, two adjustment handles 5 are symmetrically hinged. The symmetrical layout enables the two adjustment handles 5 to maintain the overall balance of the T-shaped hand-pushing frame body 4 during operation, reducing the shaking or deviation caused by unilateral operation. The operator can choose to operate the adjustment handle 5 from the left or right according to habits or needs, improving the flexibility and convenience of operation. When the two adjustment handles 5 are adjusted simultaneously, it can ensure that the traction line 6011 receives uniform and symmetrical pulling force, so that the pressing force of the lower pressing and fastening assembly 6 is more uniform and stable.

[0036] In an implementable manner, as Figure 1 and Figure 2As shown, two connecting rods 402 are connected to the top of the bow frame 401. The two connecting rods 402 are located on both sides of the vertical section of the T-shaped hand trolley frame body 4. Each connecting rod 402 is connected to the vertical section of the T-shaped hand trolley frame body 4 through a screw 403. Specifically, through the design of the two connecting rods 402 and the screw 403, the temperature-controlled waterproof coiled material paving machine realizes the stable connection between the bow frame 401 and the T-shaped hand trolley frame body 4, improving the overall stability and reliability of the paving machine.

[0037] In an implementable manner, as Figure 1 and Figure 2 shown, a plurality of perforated fixing blocks 404 are arranged at intervals along the height direction of the vertical section of the T-shaped hand trolley frame body 4. The vertical section of the inverted T-shaped air duct 202 is movably inserted through the perforated fixing blocks 404.

[0038] Specifically, a plurality of perforated fixing blocks 404 are arranged at intervals along the height direction of the vertical section of the T-shaped hand trolley frame body 4. These perforated fixing blocks 404 are fixed to the vertical section of the T-shaped hand trolley frame body 4 by welding. Each perforated fixing block 404 is provided with holes, and the diameters and positions of these holes are designed according to the dimensions of the vertical section of the inverted T-shaped air duct 202 to ensure that it can be movably inserted smoothly. The vertical section of the inverted T-shaped air duct 202, as an important component in the temperature-controlled waterproof coiled material paving machine, needs to move up and down along the vertical section of the T-shaped hand trolley frame body 4. By adjusting the position of the inverted T-shaped air duct 202 in the perforated fixing blocks 404, the stability and smoothness of the inverted T-shaped air duct 202 during movement are ensured.

[0039] Specifically, the single-chip microcomputer 302 is used to compare the temperature monitored by the temperature sensor 301 with the preset temperature threshold, and control the opening degree of the solenoid valve 303 according to the comparison result.

[0040] In the design of the temperature-controlled waterproof coiled material laying machine, the temperature control system ensures that the rolling roller 1 can be maintained within an appropriate temperature range to guarantee the laying quality and efficiency of the waterproof coiled material. The single-chip microcomputer 302, as the core controller of the temperature control system, is responsible for receiving the temperature data monitored by the temperature sensor 301 and comparing it with the preset temperature threshold. According to the comparison result, the single-chip microcomputer 302 will issue corresponding control signals to adjust the opening degree of the solenoid valve 303, thereby achieving temperature control. The solenoid valve 303, as the actuator of the temperature control system, its opening degree directly determines the temperature output of the flame nozzle 201. When the single-chip microcomputer 302 receives the temperature data sent by the temperature sensor 301, it will compare it with the preset temperature threshold and issue control signals to the solenoid valve 303 accordingly. When the temperature monitored by the temperature sensor 301 is lower than the preset minimum threshold (such as 180 °C), the single-chip microcomputer 302 will control the opening degree of the solenoid valve 303 to increase, so that the temperature of the flame nozzle 201 quickly rises back to the preset range. When the temperature monitored by the temperature sensor 301 is higher than the preset maximum threshold (such as 200 °C), the single-chip microcomputer 302 will control the opening degree of the solenoid valve 303 to decrease to reduce the temperature of the flame nozzle 201 and prevent excessive temperature from damaging the waterproof coiled material or affecting the laying quality.

[0041] It should be understood that the preset temperature threshold is set to 180 °C to 200 °C. This range is determined according to the characteristics and laying requirements of the waterproof coiled material, aiming to ensure that the waterproof coiled material can be fully softened for easy laying during the laying process and will not be deformed or damaged due to excessive temperature.

[0042] Exemplarily, the single-chip microcomputer model can be the 8051 series single-chip microcomputer, such as 80C31, 80C51, 87C51, etc.

[0043] In a typical implementation, such as Figures 1 - 2As shown in the figure, a temperature-controlled waterproof coiled material paving machine includes a rolling roller 1, a hot-melt assembly 2, a temperature control assembly, a T-shaped hand-pushing frame body 4, an adjusting handle 5, and a fastening assembly 6. The rolling roller 1 can be wound with a waterproof coiled material; the hot-melt assembly 2 includes eight groups of flame nozzles 201, a T-shaped air duct 202 (using a hose), and a gas tank 203. The temperature control assembly includes a temperature sensor 301, a single-chip microcomputer 302, and a solenoid valve 303; the fastening assembly 6 includes an inverted Y-shaped wire pipe 601, a vertical transmission rod 602, a horizontal transmission rod 603, a pressing rod 604, and a ribbed rod 605; a bow-shaped frame 401 is welded to the lower part of the T-shaped hand-pushing frame body 4; the adjusting handle 5 is fixed to the upper part of the T-shaped hand-pushing frame body 4 by an iron hoop bolt. To ensure the accuracy of the monitoring data of the temperature sensor 301, the sensor 301 is fixed near the flame nozzle 201 after being cured with high-temperature heat-conducting glue. The rolling roller 1 has a quick-disassembly and quick-assembly structure. After the waterproof coiled material is wound on the rolling roller 1, its two ends can be directly inserted into the bearings on both sides of the bow-shaped frame, and the installation can be completed by tightening the end locking nuts; both sides of the rolling roller 1 are equipped with axle center bearings, which are not easy to be eccentric and can realize dead-angle-free rotation, making the operation convenient.

[0044] The bow-shaped frame 401 is designed with a structure similar to a hacksaw. By tightening the locking nut, prestress is applied to both ends of the rolling roller 1, and the rolling roller 1 can be tensioned; to ensure the stability during use, the bow-shaped frame 401 is strengthened and fixed to the T-shaped hand-pushing frame body 4 through two connecting rods 402; the bottom of the connecting rod 402 is welded to the bow-shaped frame 401, and its two ends pass through the screw rod 403; nuts can be screwed onto the ends of the screw rod 403 for fixation to prevent the connecting rod 402 from shifting left and right. Three perforated fixing blocks 404 are welded to the T-shaped hand-pushing frame body 4, and the T-shaped air duct 202 can move up and down within the perforated fixing blocks 404 to adjust the position of the bottom flame nozzle 201. The flame nozzles 201 are evenly distributed at the front end of the waterproof coiled material to ensure uniform heating of the waterproof coiled material. A ribbed rod 605 is welded inside the bow-shaped frame 401 to increase the strength of the bow-shaped frame 401 during the use of the paving machine and provide a rotation fulcrum for the horizontal transmission rod. The fulcrum is hinged to the horizontal transmission rod 603; one end of the vertical transmission rod 602 is hinged to the horizontal transmission rod 603, and the other end is fixedly connected to the pressing rod 604.

[0045] The inverted Y-shaped wire pipe 601 is penetrated by a traction wire 6011 (steel wire). One end of the traction wire 6011 is connected to the adjusting handle 5. By squeezing the adjusting handle 5, the traction wire 6011 can be tensioned. After the traction wire 6011 is tensioned, the inner end of the lateral conduction rod 603 is lifted. The center of the lateral conduction rod 603 rotates around the fulcrum of the ribbed rod 605, and the outer end of the lateral conduction rod 603 is pressed down. The outer end of the lateral conduction rod 603 drives the vertical conduction rod 602 to displace downward. After the vertical conduction rod 602 is pressed down, it drives the entire pressing rod 604 to be pressed down. The pressing rod 604 contacts both ends of the rolling roller 1, and the downward pressure is transmitted to both ends of the pressing roller 1, thereby applying a fastening pressure to the coiled material, which is beneficial to pressing the heated waterproof coiled material tightly on the ground, making the unfolding and paving of the waterproof coiled material smoother, and improving the construction quality and paving efficiency.

[0046] The temperature sensor 301 can monitor the temperature of the flame nozzle 201 in real time and send it to the single-chip microcomputer 302. After the single-chip microcomputer 302 is burned with code firmware, after receiving the temperature value, it can judge whether the temperature of the flame nozzle 201 is within the specified heating temperature range. If the monitored temperature is lower than the required heating temperature range, the single-chip microcomputer 302 controls the solenoid valve 303 to increase the gas output of the gas cylinder 203, thereby increasing the temperature of the flame nozzle 201. Conversely, if the monitored temperature is higher than the required heating temperature range, the single-chip microcomputer 302 controls the solenoid valve 303 to reduce the gas output of the gas cylinder 203, thereby reducing the temperature of the flame nozzle 201. During the temperature adjustment process, the temperature sensor 301 continues to monitor the temperature change in real time. If the temperature reaches the preset range, the single-chip microcomputer controls the solenoid valve 303 to maintain the gas output unchanged to keep the temperature and achieve intelligent temperature control.

[0047] The working principle and usage process of this embodiment:

[0048] First, wind the waterproof coiled material around the rolling roller 1, insert both ends of the rolling roller 1 into the bearings on both sides of the bottom of the bow-shaped frame 401, and tighten the locking nuts. Check whether the rolling roller 1 rotates smoothly. The T-shaped air guide pipe 202 is connected to the gas cylinder 203, adjust the position of the T-shaped air guide pipe 202 to ensure that the flame nozzle 201 is close to the coiled material; open the gas valve of the gas cylinder 203 and ignite the flame nozzle 201 to start heating the waterproof coiled material.

[0049] Connect the power supply to supply power to the temperature sensor 301 and the single-chip microcomputer 302. The single-chip microcomputer 302 programs and sets the allowable range of the heating temperature of the flame nozzle 201 to be 180°C - 200°C. The temperature sensor 301 starts to monitor the temperature of the flame nozzle 201 as T measured and transmits the signal to the single-chip microcomputer 302. The single-chip microcomputer 302 judges through the burned firmware program. The temperature monitored by the temperature sensor 301 is divided into the following three situations:

[0050] I. When 180°C < measured temperature < 200°C, the temperature near the flame nozzle 201 meets the requirements and no adjustment is needed;

[0051] When the measured temperature < 180°C, the temperature near the flame nozzle 201 is lower than the required range. The single-chip microcomputer 302 controls the solenoid valve 303 to increase the gas output of the gas tank 203, thereby increasing the temperature of the flame nozzle 201 to reach the required temperature;

[0052] III. When 200°C < measured temperature, the temperature near the flame nozzle 201 is higher than the required range. The single-chip microcomputer 302 controls the solenoid valve 303 to reduce the gas output of the gas tank 203, thereby reducing the temperature of the flame nozzle 201 to reach the required temperature;

[0053] During the process of heating the coil material, the temperature component 3 continuously and precisely controls the temperature of the flame nozzle 201.

[0054] In summary, after continuous and uniform heating by eight groups of flame nozzles 201, the coil material can be laid. Just pinch the adjustment handle 5 by hand and press down on both ends of the rolling roller 1 to apply a downward fastening pressure on the coil material, press the heated waterproof coil material tightly on the ground, and drag the handle forward to push the T-shaped hand push frame body 4. The rolling roller 1 rolls along the bearing to drive the coil material forward for laying. During the laying process, the handle 5 can be continuously pinched to apply pressure to ensure that the coil material is laid densely and flatly.

[0055] Through the temperature control component monitored in real time in this embodiment, it can be known whether the flame temperature of the flame nozzle and the temperature near the coil material reach the melting and laying temperature of the waterproof coil material (the "Code for Acceptance of Roofing Works" GB50207-2012 requires that the heating temperature should not be higher than 200°C and the use temperature should not be lower than 180°C. For the temperature requirements of different coil materials, construction adjustment can be carried out according to the manufacturer's instructions and test reports), and the single-chip microcomputer can control the solenoid valve to increase or decrease the gas output of the gas tank, thereby raising or lowering the heating temperature to the appropriate range to avoid insufficient heating or burning through the coil material.

[0056] The center of the waterproof coil material in this embodiment runs through the rolling roller. During use, both ends of the rolling roller are fixed on the hand push frame body, and just hold the handle of the frame body and push forward to complete the paving work. During the process, a downward fastening pressure can be applied to the coil material by pinching the adjustment handle by hand and pressing down on both ends of the rolling roller, which is beneficial to pressing the heated waterproof coil material tightly on the ground, making the unfolding and laying of the waterproof coil material smoother, and improving the construction quality and laying efficiency.

[0057] Eight groups of spray gun nozzles are arranged at the lower part of the hand push frame body in this embodiment, evenly distributed at the front end of the waterproof coil material, which can fully bake and heat the entire group of coil materials in all directions, and can effectively ensure that the coil materials are heated and melted evenly.
