Description

Technical Field

[0001] This utility model relates to the field of wind power hybrid tower construction technology, and in particular to a portable structural adhesive applicator for applying structural adhesive to the ends of tunnel segments in a high-altitude environment. Background Technology

[0002] During construction, especially when splicing tunnel segments at high altitudes, applying structural adhesive to the ends of the segments is a crucial step in ensuring a stable connection.

[0003] However, existing adhesive application methods have significant technical bottlenecks: since sealing strips are usually pre-set on the edges of the pipe segments, it is difficult to achieve uniform and precise adhesive coverage when applying structural adhesive manually. Construction workers need to operate on narrow working platforms at high altitudes, and due to factors such as skill level, environmental conditions, and fatigue, it is easy to cause uneven adhesive thickness, deviation in application position, or even problems such as missed application or overflow of adhesive, which directly affect the sealing performance and structural strength of the pipe segments after splicing.

[0004] In addition, manual adhesive application at height is inefficient and cannot meet the progress requirements of large-scale construction. Furthermore, prolonged high-altitude operations significantly increase labor intensity and safety risks, easily leading to construction accidents or rework due to operational errors, further increasing project costs. Therefore, in order to solve the problems of unstable adhesive quality, low construction efficiency, and high labor intensity in existing manual adhesive application technologies, there is an urgent need for a portable segment structure adhesive application device that can adapt to high-altitude working environments and achieve efficient and precise adhesive application.

[0009] In a preferred embodiment, a glue supply device is also provided. A flexible tube connected to the center of the end of the glue tank away from the drive housing is connected to the rectangular cavity of the glue tank. The glue tank is connected to the glue supply device through the flexible tube.

[0010] In the preferred embodiment, a handheld part is fixed to the top of the drive housing, the walking system is located below the glue tank, and the glue dispensing device is set synchronously with the walking system;

[0011] The walking system includes a support structure, drive wheels, and a micro motor. One side of the support structure is fixed to one side of the rubber bucket. The output shaft of the micro motor is connected to the drive wheel through a gear transmission assembly. The walking system has built-in sensor components.

[0012] In a preferred embodiment, the glue dispensing device includes a scraper connecting part and a glue dispensing duckbill respectively fixed to the front end of the drive housing. The scraper connecting part and the glue dispensing duckbill are arranged vertically opposite each other and their ends are parallel to each other.

[0013] The end of the scraper connector is provided with a convex groove, and the scraper part can be detachably installed at the end of the scraper connector through the convex groove.

[0014] In a preferred embodiment, the scraper part includes a limiting block, a toothed scraper, and a scraper end. The toothed scraper is slidably connected to the convex groove of the scraper connection part, and a mounting hole penetrating the scraper connection part and the toothed scraper is provided on one side of the scraper connection part. One side of the limiting block is fixed to the toothed scraper.

[0015] The toothed scraper is long and narrow, and the cross-section of the toothed scraper is an isosceles trapezoid. The scraper end is the front edge of the toothed scraper. The scraper end maintains a specific vertical distance from the outlet of the glue-dispensing duckbill, forming a glue-spreading area.

[0016] In the preferred embodiment, the glue-dispensing duckbill has an L-shaped hollow guide structure, the outlet end face of the glue-dispensing duckbill has a flat structure, and the outlet direction of the glue-dispensing duckbill faces the inner side of the toothed scraper.

[0033] To better understand the purpose, structure, and function of this utility model, the embodiments and features described herein can be combined with each other without conflict. The utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] Example

[0035] like Figures 1-4 As shown in the figure, this embodiment illustrates a portable tube segment adhesive application device, including a drive housing 1, an adhesive tank 2, a fixing plate 3, and a walking system 4. The outer wall of the drive housing 1 is horizontally fixed to the adhesive tank 2 by the fixing plate 3. The device also includes an adhesive dispensing device. The walking system 4 is located below the adhesive dispensing device. The adhesive dispensing device can evenly dispense adhesive along the travel path of the walking system 4 to form an initial adhesive layer.

[0036] Furthermore, such as Figure 1 As shown, the glue bucket 2 is a rectangular cavity, which is fixed to the middle of the drive housing 1 by bolts through horizontally set fixing plates 3. There are two fixing plates 3, which are arranged in a mirror symmetrical manner. The glue bucket 2 is parallel to the length direction of the drive housing 1, which ensures the stability of the glue bucket 2 and prevents it from shaking or shifting during the operation of the device.

[0037] In this embodiment, a glue supply device 14 is also provided. The glue supply device 14 is a vacuum degassing mixer in the prior art, which is used to deliver degassed structural adhesive to the glue tank 2. The center of the end of the glue tank 2 away from the drive housing 1 is connected to a hose 6 that communicates with the rectangular cavity of the glue tank 2. The glue tank 2 is connected to the glue supply device 14 through the hose 6. The glue supply device 14 is used to provide pretreated structural adhesive to the glue tank 2 to ensure that there is sufficient adhesive liquid in the glue tank 2 for coating operations.

[0038] Furthermore, a handheld part 5 is fixed on the top of the drive housing 1, which facilitates the operation and movement of the device by construction personnel. Construction personnel can place the device at the end of the tunnel segment through the handheld part 5 and control and adjust the device during operation.

[0039] In this embodiment, as shown Figure 5 As shown, a control system is also included, integrated within the drive housing 1. This system includes a PLC controller, allowing operators to set parameters such as speed, adhesive quantity, and tooth pitch. The control system monitors the adhesive layer thickness in real time, triggering an alarm when the thickness exceeds the tolerance (<3mm or >7mm). Simultaneously, the control system also controls the adhesive injection speed and travel speed, achieving synchronized injection and travel to ensure the stability and uniformity of the adhesive coating quality.

[0040] In this embodiment, the walking system 4 is located below the rubber bucket 2, facilitating operation and movement of the device by construction personnel. Construction personnel can use the handheld part 5 to place the device at the end of the tunnel segment and control and adjust the device during operation.

[0041] The glue dispensing device is set up synchronously with the walking system 4. The walking system 4 includes a support structure, a drive wheel and a micro motor. One side of the support structure is fixed to one side of the glue tank 2 by bolts. The output shaft of the micro motor is connected to the drive wheel through a gear set to realize the autonomous movement of the device along the edge of the tube.

[0042] Furthermore, the support structure is provided with a preset tilt angle α relative to the horizontal plane of the glue bucket 2. The value of the tilt angle α ranges from 15° to 45°. This setting is intended to optimize the ease of the scraping operation of the structural adhesive. By adjusting the construction angle, the operator can more easily trim the adhesive layer, thereby improving the efficiency of the adhesive application and the flatness of the adhesive layer. The tilt angle can ensure that the contact pressure between the scraper part 8 and the end face of the tube is evenly distributed, reducing the local excessive thickness or thinness of the adhesive layer caused by vertical pressure.

[0043] The walking system 4 has built-in sensor components to control each device. The sensor components that detect the roller travel are used to monitor the number of rotations and travel distance of the roller in real time and transmit the data to the control system.

[0044] Specifically, the sensor assembly includes a Hall effect speed sensor and a photoelectric encoder. The Hall effect speed sensor monitors the rotational speed of the micro motor, and the photoelectric encoder measures the travel distance of the drive wheel assembly. The sensor assembly is electrically connected to a PLC controller inside the drive housing 1. The PLC controller dynamically adjusts the travel speed of the walking system 4 based on the sensor data.

[0045] In this embodiment, as Figure 1 , 2 As shown, the glue dispensing device includes a scraper connecting part 7 and a glue dispensing duckbill 9, which are respectively fixed to the front end of the drive housing 1. The scraper connecting part 7 and the glue dispensing duckbill 9 are arranged vertically opposite each other. The scraper connecting part 7 is parallel to the end of the glue dispensing duckbill 9. A convex groove is provided at the end of the scraper connecting part 7. A scraper part 8 is detachably installed at the end of the scraper connecting part 7 through the convex groove.

[0046] Furthermore, the scraper section 8 includes a limiting block 81, a toothed scraper 82, and a scraper end 83. The toothed scraper 82 is slidably connected to the convex groove, and a mounting hole penetrating the scraper connection section 7 and the toothed scraper 82 is provided on one side. One side of the limiting block 81 is fixed to the toothed scraper 82 by a pressure adjusting bolt to provide positioning support for the toothed scraper 82 and ensure the stability of the glue scraping operation. The toothed scraper 82 is elongated, and its tooth shape is an isosceles trapezoid with a tooth depth of 2mm and a tooth pitch of 5mm. It can control the glue layer thickness and improve uniformity. The tooth shape is used to scrape and texture the extruded structural glue, effectively avoiding the glue layer being too thick or too thin. The scraper end 83 is the front edge of the toothed scraper 82, which is 5mm perpendicular to the outlet of the glue dispensing duckbill 9, forming a glue spreading area. When the structural glue is extruded from the glue dispensing duckbill 9, it is evenly spread and scraped within this area by the toothed scraper 82.

[0047] Specifically, the trapezoidal teeth of the toothed scraper 82 can scrape off excess adhesive to both sides, while forming equidistant air venting grooves on the surface of the adhesive layer. The scraper end 83 ensures that the front edge of the adhesive strip is neat and avoids burrs.

[0048] Among them, the glue-dispensing duckbill 9 has an overall L-shaped hollow guiding structure, and the outlet end face of the glue-dispensing duckbill 9 has a flat structure. The glue strip formed by the glue-dispensing duckbill 9 has its outlet direction facing the inside of the toothed scraper 82, and the center line of the glue strip coincides with the scraping trajectory of the toothed scraper 82, ensuring that the extruded glue directly falls into the scraping area of ​​the toothed scraper 82.

[0049] Furthermore, the inside of the glue-dispensing duckbill 9 is provided with a flow distribution groove, which is used to evenly distribute the glue liquid along the width direction of the outlet end face of the glue-dispensing duckbill 9. The cross-section of the flow distribution groove is a gradually narrowing flow channel design, so that the pressure of the glue liquid is balanced during the extrusion process.

[0050] During implementation, as the device moves, the glue-dispensing duckbill 9 continuously extrudes the glue strip, the limiting block 81 adheres to the surface of the tube segment, keeping the toothed scraper 82 horizontal, and the tooth tip cuts into the top of the glue strip. The trapezoidal teeth of the toothed scraper 82 guide the excess glue on both sides to the reserved area at the edge of the tube segment, while forming an air venting groove on the surface of the glue layer to reduce the accumulation of air bubbles during curing and improve the tightness of the adhesion between the glue layer and the sealing strip.

[0051] The scraper connecting part 7 is an L-shaped metal plate, specifically stainless steel.

[0052] In this embodiment, as Figure 4As shown, the drive housing 1 integrates a control system and an electric push rod 10 fixed by a bracket. The piston rod of the electric push rod 10 is connected to a push plate 12. The push plate 12 is located inside the glue tank 2, and the outer wall of the push plate 12 slides against the inside of the glue tank 2. The piston 13 has a rectangular structure, and the outer wall of the piston 13 is adapted to the inner wall of the glue tank 2. The piston 13 is provided on the push plate 12. The electric push rod 10 drives the piston 13 to move axially inside the glue tank 2 through reciprocating motion to realize the quantitative delivery of structural adhesive.

[0053] The device also includes a sealing bushing 11. The sealing bushing 11 is made of fluororubber. The outer diameter of the piston rod of the electric push rod 10 is press-fitted with the inner wall of the rubber barrel 2 through the sealing bushing 11 to form a sealing rubber cavity.

[0054] Based on the cooperation between the above structures, its specific working principle is as follows:

[0055] The scraper part 8 is aligned with the convex groove of the scraper connecting part 7. The scraper part 8 is inserted into the convex groove of the scraper connecting part 7 by sliding connection. The scraper part 8 is fixed by bolts passing through the mounting holes on the scraper connecting part 7 and the scraper part 8. The pre-treated structural adhesive is injected into the glue tank 2 from the glue supply device 14. After filling, the feed port is closed.

[0056] The construction worker holds the handheld part 5 and places the device at the end of the pipe segment, ensuring that the front edge 83 of the toothed scraper 82 is fully in contact with the surface. The drive wheel of the walking system 4 is aligned with the guide groove at the edge of the pipe segment. The worker sets the walking speed and the electric push rod stroke through the handheld part 5 and starts the device. The drive wheel rolls, causing the device to move around the pipe segment. At the same time, the electric push rod pushes the piston 13, causing the adhesive to be squeezed out through the glue dispensing duckbill 9. During the movement of the device, the toothed scraper 82 scrapes the adhesive strip in real time, and excess adhesive is guided to the edge along the scraper end 83.

[0057] After the device completes one week of adhesive application, it automatically stops. Then, the hose 6 is disconnected, the scraper connection 7 is disassembled, and the residual adhesive on the toothed scraper 82 is cleaned. The remaining adhesive in the adhesive bucket 2 can be discharged through the piston 13, which facilitates the replacement of different types of structural adhesive.
