DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Example 1:

[0028] See also Figure 1-4The present invention provides a technical solution: an auxiliary repair device for cracks in a roof waterproof protective layer and a method of use, comprising a trolley platform 1, a handrail 2 and a fixing frame 3 are installed on the trolley platform 1, a barrel 4 is installed on the fixing frame 3, a discharge mechanism is provided at the bottom of the barrel 4, the discharge mechanism is used to discharge the repair filler contained in the barrel 4, a plurality of push rod motors 5 are installed on the trolley platform 1, and a support plate 6 is commonly connected between each push rod motor 5.

[0029] The unloading mechanism includes a partition 14, a unloading barrel 15, a side plate 16, a guide rod seat 17, and a push plate 19. The outer array of the partition 14 is connected to a connecting rod 21, and is connected to the inner wall of the barrel 4 through the connecting rod 21. The unloading barrel 15 is slidably sleeved in the barrel 4, and the upper end of the unloading barrel 15 cooperates with the partition 14 with a sleeve. The side plate 16 is connected to the outer side of the unloading barrel 15 below the barrel 4, the guide rod seat 17 is connected to the outer side of the barrel 4, the side plate 16 is slidably sleeved on the outer side of the guide rod seat 17, and the push plate 19 is connected to the support plate 6, and the push plate 19 cooperates and conflicts with the upper end surface of the side plate 16.

[0030] like Figure 2 As shown, the support plate 6 is driven downward by the push rod motor 5, which can drive the push plate 19 to move downward. The push plate 19 resists the downward movement of the side plate 16, pulling the lower barrel 15 to slide downward at the lower end of the barrel 4, so that the clamping sleeve between the upper end of the lower barrel 15 and the partition 14 is cancelled, and then the concrete slurry will enter the lower barrel 15 from between the partition 14 and the inner wall of the barrel 4, and flow out from the lower end pipe mouth of the lower barrel 15 that has already descended to the corresponding crack to fill the crack.

[0031] A spring 18 is sleeved on the outer side of the guide rod seat 17, and the two ends of the spring 18 are respectively connected to the barrel 4 and the side plate 16. The setting of the spring 18 allows the side plate 16 to pull the side plate 16 and the lower barrel 15 upward when there is no interference from the push plate 19, and let the lower barrel 15 contact with the partition tube 14 again to seal the concrete slurry contained in the barrel 4.

[0032] The lower end of the barrel 4 is in the slide 7, and the side plate 16, the guide rod seat 17, and the push plate 19 are all in the slide 7. The setting of the slide 7 is also conducive to the passage of the lower end of the barrel 4, and it is convenient for it to pass through the slide 7 to the bottom of the trolley platform 1 to realize the unloading operation.

[0033] A slideway 7 is provided through the support plate 6 and the trolley platform 1. The support plate 6 is connected to a slide rail 8. A slide plate 9 is slidably connected in the slide rail 8, and a scraping mechanism is provided at the lower end of the slide plate 9. The scraping mechanism is used to scrape and evenly mix the material discharged from the barrel 4.

[0034] The scraper mechanism includes a vertical plate 10, a mounting seat 11, a scraper 12, a limit seat 13, and a guide plate 20. The lower end of the slide 9 is connected to the vertical plate 10, and the mounting seat 11 is connected to the lower end of the vertical plate 10. The scrapers 12 are symmetrically connected to the two sides of the mounting seat 11 through a scroll hinge. The limit seat 13 is connected to the mounting seat 11, and the scraper 12 cooperates and conflicts with the limit seat 13. The guide plate 20 is connected to the lower side of the trolley platform 1, and the scraper 12 slides and conflicts with the guide plate 20. The mounting seat 11 and the limit seat 13 are slidably connected in the guide plate 20, so that the scraper 12 can cooperate and conflict with the guide plate 20. When the slides 9 on both sides approach each other, the scraper 12 is driven to overcome the elastic force of the spring hinge and rotate to be stored in the guide plate 20. Otherwise, it is unfolded until it cooperates and conflicts with the limit seats 13 on both sides to limit.

[0035] like Figure 1 As shown in or 3, when the support plate 6 moves downward, it will drive the slide rail 8, the slide plate 9, the vertical plate 10, the mounting seat 11 and the scraper 12 rotatably connected to the mounting seat 11 through a spring hinge to move downward, so that the scraper 12 can contact the ground. At the same time, the slide rails control the slides on both sides to move away from each other, so that the mounting seats 13 at both ends of the guide plate 20 move away from each other. In the absence of the guide plate 20, the scraper 12 can be rotated from a state parallel to the guide plate 20 to a state parallel to the guide plate 20. By pulling the trolley platform 1, the scraper 12 can be driven to scrape and smooth the concrete slurry that has been filled in the cracks in the ground.

[0036] The slide rail 8 adopts a linear screw guide rail, a linear roller guide rail, etc. in the prior art.

[0037] The method for using the roof waterproof protective layer crack auxiliary repair device in the above embodiment has the following specific steps:

[0038] S1, preparation stage: put the pre-made concrete slurry into the barrel 4; move the device to the roof crack through the handrail 2 on the trolley platform 1;

[0039] S2, feeding stage: adjust the support plate 6 downward to align the feeding barrel 15 with the crack; fill the concrete slurry in the barrel 4 into the crack through the feeding mechanism. The specific operation is as follows:

[0040] The push rod motor 5 pushes the support plate 6 downward, driving the push plate 19 to contact the side plate 16, and then pushing the lower barrel 15 downward, so that the concrete slurry flows out of the lower barrel 15 and fills the cracks; the spring 18 plays a buffering and reset role when the side plate 16 moves;

[0041] S3, scraping stage: As the support plate 6 moves downward, the slide plate 9 drives the scraping mechanism downward until it contacts the ground; the slide rail 8 slides, driving the slide plate 9 to move, so that the scraper 12 is expanded under the action of the guide plate 20, and the concrete slurry filled in the crack is scraped and smoothed. The specific operation is as follows:

[0042] The scraper 12 rotates and unfolds through the scroll hinge, cooperating with the limit seat 13 to ensure that the angle and position of the scraper 12 are suitable for the scraping operation; under the guidance of the guide plate 20, the scraper 12 slides along the crack direction to ensure that the concrete slurry is evenly distributed;

[0043] S4, completion stage: After the scraping is completed, the push rod motor 5 drives the support plate 6 to move upward, so that the discharge barrel 15 and the scraping mechanism are reset; the device is removed to complete the crack repair;

[0044] Through the above steps, the device can effectively fill the cracks with concrete slurry and smooth it evenly through the scraper 12, ensuring that the repaired roof waterproof protective layer is not prone to secondary cracking.

[0045] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
