Description

Technical Field

[0001] This invention relates to the technical field of prefabricated flood control and water-retaining wall construction equipment, and in particular to a waterproof adhesive spraying device for the corners of prefabricated flood control and water-retaining walls. Background Technology

[0002] Prefabricated flood retaining walls are widely used in urban flood control and river flood prevention due to their convenient assembly and disassembly and strong adaptability. The sealing and waterproofing performance of their corners, both inside and outside, directly determines the overall flood control effect. Currently, the sealing of the corner gaps of flood retaining walls is mostly done manually, requiring the sequential steps of cleaning the gaps, applying adhesive, and scraping the adhesive, which has the following technical drawbacks:

[0003] The positioning accuracy is low, and manual operation makes it difficult to ensure that the cleaning, gluing, and scraping mechanisms are always aligned with the center line of the corner gaps. This is especially true for non-standard corners, which are prone to glue layer misalignment and missed coating, affecting waterproof sealing. The work efficiency is low, as the three processes need to be manually operated step by step, and the limited space at corners makes operation difficult and cannot meet the rapid operation requirements of flood control emergency construction. The structural adaptability is poor. Existing glue application devices are mostly designed for standard 90° corners and cannot adapt to different angles such as inside and outside corners. The track positioning is unstable, and the mechanism is prone to displacement due to vibration during operation. The transmission structure is unreasonable. In some devices, the rotary drum drive is disconnected from the positioning structure, which can easily cause deviations when switching work positions and cannot guarantee the consistency of the operation trajectory of the three processes.

[0004] Therefore, it is necessary to design a corner waterproofing and caulking device that is precise in positioning, highly adaptable, and integrates operations to address the technical shortcomings of existing manual labor and equipment, and improve the construction quality and efficiency of corner sealing of prefabricated flood control retaining walls.

[0051] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0052] like Figures 1-8 The prefabricated waterproof adhesive spraying device for the corner of a flood control retaining wall shown includes a track assembly, a movement drive assembly, and an operation assembly. The structure and cooperation relationship of each component are as follows:

[0053] Track 1 component

[0054] The track 1 assembly serves as the operational guide reference for the device. It consists of a vertical section 101 at the inside corner, a vertical section 102 at the outside corner, and an arc section 103. The arc section 103 is fixedly connected to the top of the vertical sections 101 at the inside corner and 102 at the outside corner, and the entire assembly is located above the wall. The three components form an integrated structure that not only fits the corner contour of the retaining wall but also provides sufficient space for the rotating drum 5 to switch the work positions of the cleaning mechanism 6, the glue application mechanism 7, and the glue scraping mechanism 8. This ensures that the moving drive assembly moves smoothly along the corner trajectory while meeting the space requirements for mechanism switching.

[0055] The bottom of the vertical section 101 at the inside corner is provided with an angle adjustment and positioning mechanism 2, which is used to adapt to different included angles of the inside corner of the retaining wall and to accurately position the vertical section 101 at the bisector of the inside corner, providing a reference for the subsequent operation mechanism to align the gap; the bottom of the vertical section 102 at the outside corner is provided with a matching clamping and positioning mechanism 3, which works with the angle adjustment and positioning mechanism 2 to achieve bidirectional stable positioning of the track 1 component and prevent the track 1 from shifting during operation.

[0056] Mobile driver components

[0057] The moving drive assembly includes a moving block 4, a first drive component, and a second drive component. The moving block 4 is slidably mounted on the track 1 assembly. Its inner wall is provided with a guide slider. The outer wall of the track 1 assembly is provided with a matching guide groove. The guide groove is opened along the extension direction of the track 1 assembly. The guide slider is embedded in the groove to ensure that the moving block 4 slides linearly along the track 1 without radial offset.

[0058] The first driving component is a micro servo motor, which is mounted on the moving block 4. Its output end is equipped with a gear 402. The outer wall of the track 1 assembly is equipped with a rack along the extension direction. The gear 402 meshes with the rack to drive the moving block 4 to move back and forth along the track 1 assembly, providing linear power for the operation. The second driving component is a motor, which is mounted on the moving block 4 and is used to drive the rotating drum 5 to rotate around its own axis to realize the switching of the work position.

[0059] The outer wall of the movable block 4 is fixedly provided with a ring frame 401, which is sleeved on the outside of the track 1 assembly. The inner wall of the rotating cylinder 5 is slidably engaged with the outer wall of the ring frame 401, so that the rotating cylinder 5 can rotate smoothly around its own axis. The inner wall of the rotating cylinder 5 is fixedly provided with a gear ring 501. The output end of the second drive unit extends to the inner side of the ring frame 401 and is fixedly provided with a gear 402. The gear 402 meshes with the gear ring 501, and drives the rotating cylinder 5 to rotate through meshing transmission. The transmission is stable and has high precision.

[0060] Job components

[0061] The working components include a rotating drum 5, a cleaning mechanism 6, an adhesive application mechanism 7, and an adhesive scraping mechanism 8. The rotating drum 5 is sleeved on the outside of the track 1 component and rotates through a sliding engagement with the ring frame 401. At the same time, it moves along the track 1 component with the moving block 4 to ensure that the working mechanism completes the trajectory movement and work station switching synchronously.

[0062] The cleaning mechanism 6, the adhesive application mechanism 7, and the adhesive scraping mechanism 8 are installed at intervals along the outer side wall of the rotating drum 5. The rotating drum 5 is driven to rotate by the second drive component. Any of the mechanisms can be switched to the working position facing the corner gap: the cleaning mechanism 6 is used to remove debris, dust and water stains in the gap, providing a clean adhesive base surface; the adhesive application mechanism 7 is used to accurately squeeze the sealant into the gap to form an adhesive layer; the adhesive scraping mechanism 8 is used to smooth and compact the adhesive and trim the rounded transition surface to improve the sealing performance.

[0063] Each detailed mechanism structure

[0064] (1) Angle adjustment and positioning mechanism 2: including a horizontal mounting base 201, a slider 202, two rotating positioning rods 203 and two connecting rods 204. The horizontal mounting base 201 is fixed to the bottom of the vertical section 101 of the inside corner and extends in the direction perpendicular to the vertical section 101 of the inside corner. The slider 202 is slidably mounted on the horizontal mounting base 201 and is provided with a locking element for locking the position. The two rotating positioning rods 203 are symmetrically hinged on the top two sides of the horizontal mounting base 201, and the free end is the wall-mounted working end and is provided with a wear-resistant rubber pad. The two ends of the connecting rods 204 are respectively hinged to the middle of the slider 202 and the rotating positioning rod 203. Moving the slider 202 can drive the rotating positioning rod 203 to open and close synchronously, so that the vertical section 101 of the inside corner is always located on the bisector of the included angle.

[0065] (2) Matching clamping and positioning mechanism 3: including horizontal slide rod 301, two hinged positioning rods 302, two clamping plates 303 and locking assembly. The horizontal slide rod 301 is horizontally slidably connected to the bottom of the vertical section 102 of the external corner and is perpendicular to each other, and can slide to clamp the bottom of the external corner. The two hinged positioning rods 302 are symmetrically hinged to the top two sides of the horizontal slide rod 301. The clamping plate 303 is rotatably connected to the free end of the positioning rod. It is made of elastic rubber and has anti-slip ridges against the wall surface to adapt to the curved surface of the wall. The locking assembly includes slide rod locking bolt and clamping rod locking screw, which respectively lock the position of the horizontal slide rod 301 and the angle of the positioning rod to achieve stable clamping.

[0066] (3) Cleaning mechanism 6: includes a mounting bracket, a blower nozzle and an air guide hose. The mounting bracket is fixed to the rotating drum 5. The air outlet of the blower nozzle faces the axis of the track 1 (aligned with the gap). The air guide hose connects the blower nozzle to an external compressed air source, which can penetrate deep into the gap to remove debris.

[0067] (4) Glue application mechanism 7: including glue tube fixing seat, glue nozzle and glue supply pipeline. The glue tube fixing seat is used to place the glue tube. The glue nozzle is aligned with the gap and can penetrate into the gap. The glue supply pipeline connects the glue nozzle to the external glue supply pump. The glue tube fixing seat is equipped with a glue quantity adjustment knob to control the extrusion amount.

[0068] (5) Glue scraping mechanism 8: including scraper bracket, elastic scraper and height adjustment component. The elastic scraper is made of silicone material and the working end is a round arc structure to adapt to the corner contour. The height adjustment component can adjust the adhesion pressure between the scraper and the wall to ensure that the glue layer is scraped into a round arc transition surface.

[0069] In this embodiment, during operation:

[0070] 1. Equipment assembly

[0071] First, the vertical section 101 at the inside corner and the vertical section 102 at the outside corner are detachably connected via the arc section 103 through a flange to form an integrated track 1 assembly, ensuring that the radius of curvature of the arc section 103 matches the corner transition contour of the retaining wall and is located above the wall. The angle adjustment and positioning mechanism 2 is fixed to the bottom of the vertical section 101 at the inside corner, and the matching clamping and positioning mechanism 3 is installed at the bottom of the vertical section 102 at the outside corner. The moving block 4 is embedded into the guide groove of the track 1 assembly through the guide slider to complete the sliding assembly. The first driving component and the second driving component are respectively installed in the preset installation position of the moving block 4. The gear 402 of the first driving component meshes with the rack of the track 1 assembly, and the gear 402 of the second driving component extends into the inner side of the ring frame 401 and meshes with the gear ring 501 on the inner wall of the ring frame 401. The rotating cylinder 5 is sleeved on the outside of the ring frame 401 to complete the sliding fit assembly. The cleaning mechanism 6, the glue application mechanism 7, and the glue scraping mechanism 8 are fixed at intervals along the circumferential direction of the outer wall of the rotating cylinder 5.

[0072] 2. Track 1 positioning

[0073] (1) Corner positioning: Place the horizontal mounting base 201 at the bottom of the vertical section 101 of the corner close to the corner of the water-retaining wall, slide the slider 202, and drive the two rotating positioning rods 203 to open and close synchronously through the connecting rod 204 until the rubber pads at the free end of the rotating positioning rods 203 are completely in contact with the walls on both sides of the corner. At this time, the vertical section 101 of the corner is located on the bisector of the corner. Tighten the locking piece on the slider 202 to lock the position of the angle adjustment positioning mechanism 2.

[0074] (2) External corner positioning: Slide the horizontal slide bar 301 at the bottom of the vertical section 102 of the external corner to make it press against the bottom of the external corner of the water-retaining wall. Rotate the two hinged positioning rods 302 to drive the clamping plate 303 to fit against the wall on both sides of the external corner. The elastic rubber material of the clamping plate 303 is adapted to the slight curvature of the wall. Tighten the slide bar locking bolt to lock the horizontal slide bar 301. Tighten the clamping rod locking screw to lock the angle between the two hinged positioning rods 302. The bidirectional stable positioning of the track 1 component is completed. The track 1 can be put into operation if there is no displacement when gently pushed.

[0075] 3. Integrated operation

[0076] The curved segment 103 is located above the wall, providing ample space for mechanism switching, avoiding interference with the wall, and ensuring orderly connection of each process:

[0077] (1) Cleaning operation of the front of the inside corner: Start the second drive unit, and drive the rotating drum 5 to rotate through the meshing of gear 402-gear ring 501 until the cleaning mechanism 6 is aligned with the gap on the front of the inside corner; connect the air guide hose of the cleaning mechanism 6 to the external compressed air source, start the first drive unit, and drive the moving block 4 and the rotating drum 5 to move slowly from bottom to top along the vertical section 101 of the inside corner, and blow air into the gap to thoroughly remove debris, dust and water stains, and complete the cleaning operation of the front of the inside corner.

[0078] (2) Applying adhesive to the front of the inside corner: After cleaning, start the first drive to drive the moving block 4 and the rotating drum 5 to the position of the arc segment 103. Use the reserved space of the arc segment 103 to unlock the positioning and locking structure. Start the second drive to drive the rotating drum 5 to rotate until the adhesive application mechanism 7 is aligned with the inside corner gap. Connect the adhesive supply pipeline of the adhesive application mechanism 7 to the external adhesive supply pump. Set the extrusion amount through the adhesive quantity adjustment knob. Start the first drive to drive the adhesive application mechanism 7 to move at a uniform speed from top to bottom along the vertical section 101 of the inside corner, and accurately extrude the sealant to fill the gap. After applying adhesive from top to bottom, keep the position of the adhesive application mechanism 7 unchanged, start the first drive in the opposite direction, and drive the adhesive application mechanism 7 to apply adhesive from bottom to top again. By applying adhesive back and forth, ensure that the adhesive in the gap is fully filled and free of air bubbles, and complete the adhesive application operation on the front of the inside corner.

[0079] (3) Applying adhesive to the front of the inside corner: After the adhesive is applied, start the first drive again to move the moving block 4 and the rotating cylinder 5 to the position of the arc segment 103, unlock the positioning and locking structure, start the second drive to drive the rotating cylinder 5 to switch to the adhesive scraping mechanism 8, align the inside corner gap, adjust the adhesion pressure between the elastic scraper and the wall through the height adjustment component, start the first drive to drive the elastic scraper to scrape and compact the adhesive layer from top to bottom along the vertical segment 101 of the inside corner; after the adhesive is scraped from top to bottom, start the first drive in the opposite direction to drive the elastic scraper to scrape the adhesive again from bottom to top, and trim a smooth and flat arc transition surface to avoid cracking of the adhesive layer at the corners, thus completing the adhesive scraping operation on the front of the inside corner.

[0080] (4) External corner operation: Start the first drive unit to move the moving block 4 and the rotating cylinder 5 along the arc segment 103 to the vertical segment 102 of the external corner. Follow the internal corner operation process to complete the operation without repeating steps: First, clean the external corner gap from bottom to top through the cleaning mechanism 6. Then, rise to the arc segment 103 and switch the glue application mechanism 7 to apply glue back and forth to fill the gap. Then, rise to the arc segment 103 and switch the glue scraping mechanism 8 to scrape the glue back and forth to repair the glue surface, ensuring that the external corner gap is fully sealed and the glue surface is flat, so as to achieve full sealing of the corner area without any dead corners.

[0081] After the work is completed, loosen the locking components and the locking parts of the angle adjustment and positioning mechanism 2, remove the flange of the track 1 component, and disassemble and store each part for easy transportation and next use.
