Description

Technical Field

[0001] The invention relates to the technical field of liquid waterproof coating paving, in particular to a paving system and a paving method. Background Art

[0002] Paving is an important construction method in the field of architecture and engineering. It refers to the uniform arrangement, coating or laying of specific materials on the target surface to achieve functional or decorative effects. The application range of paving is very wide. Liquid waterproof coating paving is one of the very important categories. It plays a protective role in building structures. Whether it is a basement, roof, bridge, pool or tunnel, the waterproof layer is to prevent external moisture from invading the interior of the structure, or to prevent internal moisture from leaking to the outside. Liquid waterproof coating is a waterproof material that is directly applied to the construction surface in liquid form. After curing, it forms a continuous and seamless waterproof membrane layer, which fits the base surface completely without leaving any gaps to achieve waterproof paving.

[0003] When paving liquid waterproof coatings, it is necessary to sequentially coat the base layer and the surface layer of coatings on the paving surface. The current paving equipment needs to first complete the coating of the base layer, and then clean, adjust or replace the equipment to coat the surface layer of coating. The switching process is cumbersome and time-consuming. A long equipment switching process can easily lead to a long surface drying time for the base layer of coating. When overcoating the surface layer of coating, interlayer separation or bubble problems may occur, affecting the waterproof performance and adhesion of the coating. In addition, since the surface layer of coating loses the optimal overcoating time window, it is difficult for the surface layer of coating to fully combine with the base layer, resulting in a decrease in the overall performance of the coating after final paving.

[0004] In addition, since liquid waterproof coatings are usually composed of film-forming materials (such as polymer emulsions), fillers (such as silicates, quartz powder), additives and solvents, the filler particles are heavy and may gradually settle to the bottom of the container due to gravity after standing for a long time, forming a precipitate, while light components (such as solvents or some additives) may float to the liquid surface, resulting in stratification. During long-term paving operations, the coating is often in a static state, which will aggravate this phenomenon, thereby affecting the uniformity and construction effect of the coating, and further reducing the quality of the paving waterproof layer. Summary of the invention

[0005] The present invention provides a paving system and a paving method, which solve the problems that the existing paving equipment is cumbersome to switch, and needs to be cleaned and adjusted to switch from the base coating to the surface coating. This process is time-consuming and may cause the base coating to take too long to dry on the surface, resulting in stratification or bubbles when the surface coating is overcoated, affecting the waterproof performance and adhesion of the coating; and the technical problem that during the long-term static operation of the liquid coating, the filler particles will settle to the bottom of the container, and the light components will float to the liquid surface, causing the coating to stratify, affecting the uniformity of the coating and the construction effect, thereby reducing the quality of the waterproof layer.

Two coating components 55 are symmetrically arranged on the V-shaped frame 54. An arc-shaped cover plate 56 is fixedly connected to the rectangular frame 4 through a connecting rod. Two feeding pipes 57 corresponding to the coating components 55 and distributed in rotational symmetry are embedded on the arc-shaped cover plate 56. A flexible connecting pipe 58 is commonly arranged between the feeding pipe 57 and the corresponding storage cylinder 3. A disc 510 is fixedly connected to the arc-shaped lower wall of the arc-shaped cover plate 56, and two material passages 511 are provided in the disc 510 and along its radial direction and are distributed in a rotationally symmetrical manner for connecting the feed pipe 57 and the coating assembly 55 corresponding to the feed pipe 57. The two material passages 511 are distributed in an X shape, and a control rotation and cutting unit 59 for controlling the rotation of the disc 510 to drive the material passage 511 to rotate to the position of the feed pipe 57 corresponding to the same is provided between the rectangular frame 4 and the rotating shaft 53. A docking tube 9 is slidably connected to the lower end of the feed pipe 57, and an annular elastic sealing ring is fixedly connected to the lower end of the docking tube 9, and a top spring is fixedly connected between the docking tube 9 and the inner cavity of the feed pipe 57.

[0037] See also Figure 5 The controlled rotation and cutting unit 59 includes two sliding rods 591 which are symmetrically fixedly connected between the left and right cavity walls of the rectangular frame 4 and located directly above the rotating shaft 53. The sliding rods 591 are slidably connected to a strip sliding seat 592 by interference fit on the outside. A gear ring 593 is fixedly connected to the outside of the rotating shaft 53. A rack 594 meshing with the gear ring 593 is fixedly connected to the lower end surface of the strip sliding seat 592. Two limit blocks 595 are symmetrically fixedly connected to the lower end surface of the strip sliding seat 592.

[0038] See also Figure 5 , Figure 6 and Figure 7 The coating assembly 55 includes a strip scraper plate 551 fixedly connected to the V-shaped frame 54 and two flexible telescopic output tubes 552 that are rotationally symmetrically distributed and embedded and fixedly connected to the V-shaped frame 54 and correspond to the material passage 511. The upper end of the flexible telescopic output tube 552 is connected to the lower end of the corresponding material passage 511, and the end of the flexible telescopic output tube 552 away from the disc 510 is connected to a strip coating head 553 embedded and fixedly arranged on the strip scraper plate 551. The lower end surface of the sliding frame 51 is fixedly connected with a fixing rod symmetrically on the left and right sides, and the end of the fixing rod away from the sliding frame 51 is fixedly connected with an arc baffle 7.

[0039] The paints used for the bottom layer and the surface layer are poured into the two storage cylinders 3 in sequence, and then the roller 10 is driven to rotate manually or through an external driving device to drive the door frame 1 to move to the paved ground, and then the reciprocating electric telescopic rod 52 is controlled to drive the slide frame 51 to move back and forth horizontally in the rectangular frame 4. When the reciprocating electric telescopic rod 52 drives the slide frame 51 to move to the right, the strip slide seat 592 and the slide rod 591 are connected in an interference fit manner, so The slide frame 51 will move before the bar slide 592. The slide frame 51 drives the ring gear 593 to rotate on the rack 594 through the rotating shaft 53. The ring gear 593 then drives the V-shaped frame 54 to rotate counterclockwise through the rotating shaft 53 until the ring gear 593 moves to the right and hits the limit block 595 on the right. Then the ring gear 593 stops rotating, and the slide frame 51 drives the rack 594 to move horizontally synchronously through the ring gear 593. The rack 594 then drives the bar slide 592 to move to the right.

[0040] The rotation of the V-shaped frame 54 will also drive the disc 510 to rotate synchronously. The rotation of the disc 510 drives the material passage 511 to change its position. When the gear ring 593 moves to the right and contacts the limit block 595 on the right, the material passage 511 at the front rotates to a position connected with the lower end of the feed pipe 57 on the right. At this time, the top spring at the right pushes the docking pipe 9 downward tightly, and the docking pipe 9 then pushes the annular elastic sealing ring to tightly contact and squeeze the edge of the upper port of the material passage 511 at the front. The base coating in the storage cylinder 3 on the right flows into the flexible connecting pipe 58, then enters the feed pipe 57, and then enters the material passage 511 through the docking pipe 9, and then enters the flexible telescopic output pipe 552, and finally enters the strip coating head 553 to be coated on the ground. The rotating V-shaped frame 54 drives the strip scraper plate 551 on the left to contact the ground, and the strip scraper plate 551 on the left scrapes the base coating coated on the ground with the lateral movement of the V-shaped frame 54.

[0041] When the slide frame 51 moves to the right position of the rectangular frame 4, the coating of the bottom layer on the ground is completed, and then the reciprocating electric telescopic rod 52 drives the slide frame 51 to switch to move to the left, and the slide frame 51 then drives the gear ring 593 to move left on the rack 594 through the rotating shaft 53. The gear ring 593 moves left and is driven by the rack 594 to rotate. The gear ring 593 then drives the V-shaped frame 54 to rotate clockwise through the rotating shaft 53, and the above steps are repeated in reverse until the gear ring 593 moves to the left and contacts the limit block 595 on the left. At this time, the gear ring 593 stops rotating, and the slide frame 51 drives the V-shaped frame 54, the rotating shaft 53, the gear ring 593, the rack 594 and the strip slide 592 to move left as a whole.

[0042] When switching to clockwise rotation, the disc 510 will be driven to rotate synchronously, and the disc 510 will then drive the two material passages 511 to rotate in the opposite direction to adjust the position, so that the upper end of the material passage 511 located at the front is rotated to be misaligned with the lower end of the feed pipe 57 located on the right, that is, the material passage 511 located at the front and the feed pipe 57 located on the right become disconnected from each other; and the material passage 511 located at the rear is rotated to a position connected with the lower end of the feed pipe 57 located on the left, and the above-mentioned steps of connecting the front material passage 511 with the lower end of the right feed pipe 57 are repeated, and the surface coating is passed into the coating component 55 located on the right, and the coating component 55 on the right quickly coats the surface coating on the surface of the base coating that has been laid previously.

[0043] When the V-shaped frame 54 switches the lateral direction and automatically switches the rotational direction to adjust the position during the lateral reciprocating movement, the strip scraper plate 551 driven upward by the rotation of the V-shaped frame 54 will move to the arc baffle plate 7, and the arc baffle plate 7 is used to shield the strip scraper plate 551, thereby preventing the strip scraper plate 551 from dripping onto the surface of the subsequently paved surface paint or base paint after scraping the base paint or surface paint.

[0044] Then, by controlling the rotation of the roller 10, the portal frame 1 is pushed to move to the next position, and then the reciprocating electric telescopic rod 52 drives the slide frame 51 to move to the right and the subsequent steps are repeated to pave the next position.

[0045] See also Figure 4 In this embodiment, a stirring mechanism 6 for stirring the paint is provided in the storage tube 3. The stirring mechanism 6 includes a support plate 61 fixedly connected to the inner cavity of the storage tube 3 and a shaft rod 62 rotatably connected to the support plate 61.

[0047] See also Figure 3The transmission unit 84 includes a horizontal support plate 841 fixedly connected between the left and right opposite sides of the portal frame 1, and the lower end surface of the horizontal support plate 841 is symmetrically fixedly connected with a vertical axis, and the vertical axis and the outside of the shaft rod 62 are respectively fixedly connected with a transmission wheel 842, and the outside of the transmission wheel 842 is commonly connected with a transmission belt 843 for transmission, and the outside of the rear transverse section of the transmission belt 843 is fixedly connected with a connecting frame 844, and the upper end of the two-way telescopic rod 82 is hinged to the rear of the connecting frame 844.

[0048] The sliding frame 51 will move back and forth laterally while driving the lever 83 to move synchronously. The lever 83 will then drive the two-way telescopic rod 82 to swing back and forth around the rotating column. During the reciprocating swing of the two-way telescopic rod 82, its upper end will drive the connecting frame 844 to move back and forth laterally. The connecting frame 844 will then drive the transmission belt 843 to rotate back and forth. The transmission belt 843 will then drive the transmission wheel 842 to rotate back and forth. The two transmission wheels 842 at the front will then drive the shaft rod 62 to swing back and forth. The shaft rod 62 will then drive the paddle 63 to swing back and forth, stirring the paint in the storage tube 3, ensuring that the liquid paint is always in motion during the long-term paving operation, avoiding the sedimentation and separation due to standing still.
