Description

Technical Field

[0001] The invention relates to the technical field of subway cover construction, in particular to a waterproof material coating device used for subway station cover construction. Background Art

[0002] With the continuous advancement of urbanization, subways have become an important part of modern urban transportation. Subway overground development, that is, the use of ground space along subway lines or near subway stations for comprehensive development, including commercial, office, residential and other functions, not only optimizes land use efficiency and improves the comprehensive economic benefits of the city, but also improves the living environment and transportation experience of urban residents.

[0003] CN202010362017.7 discloses a construction method for the upper cover of a subway parking garage. During the construction process, a reserved concrete column is chiseled manually. First, a pneumatic pick is used to chisel a circle on the surface of the reserved concrete column to form a gap to expose the steel bar. Figure 6 The chiseling depth is the thickness of the steel bar protective layer. After the reserved concrete column is chiseled to the top plate structure surface layer, the waterproof protective layer within 30cm around the reserved concrete column should be chiseled to facilitate the later construction of the frame column. Waterproof paste is used to fill the joints at the cutting position of the waterproof layer. However, due to the uneven surface of the cutting position of the waterproof layer during the chiseling process, invisible cracks are prone to leakage when the waterproof paste is applied, which affects the waterproof quality. In the later period, the upper cover building is prone to water seepage into the subway station.

[0027] Specifically, the driving member includes a second motor 10 and a gear 11 and a gear ring 12 that mesh with each other. The second motor 10 is vertically fixed on the flat plate 7, the gear 11 is fixed on the main shaft of the second motor 10, and the gear ring 12 is fixedly mounted on the outer circumference of the rotating ring 3. In this way, when the second motor 10 drives the gear 11 to rotate, the rotating ring 3 can rotate in the base ring 2 under the meshing action of the gear 11 and the gear ring 12.

[0028] Specifically, in the present embodiment, two waterproof material roller brush assemblies are symmetrically installed on the lower side of the rotating ring 3, and the waterproof material roller brush assembly includes a suspension rod 13, a guide rod 14 and a brush roller 15. The upper end of the suspension rod 13 is fixedly connected to the lower side of the rotating ring 3, and the lower side of the suspension rod 13 is provided with a horizontally penetrating guide hole. The guide rod 14 is slidably connected in the guide hole, and one end of the guide rod 14 is fixedly connected to a base plate 16, and the other end of the guide rod 14 is fixedly connected to an anti-falling plate 17. A first spring 18 mounted on the guide rod 14 is fixedly connected between the suspension rod 13 and the base plate 16. The brush roller 15 is vertically rotatably connected to the lower side of the base plate 16, and the waterproof material liquid supply mechanism provides a waterproof solution to the brush roller 15. The elastic force of the first spring 18 ensures that when the coating roller 15 moves along the side wall of the waterproof layer cutting position 46, the coating roller 15 is always in tight contact with the side wall of the waterproof layer cutting position 46, so that the coating roller 15 can rise and fall with the uneven surface of the side wall of the waterproof layer cutting position 46, avoiding invisible cracks and missing coating.

[0029] Specifically, a rotating hole which passes through the base plate 16 from top to bottom is provided, in which a sleeve 19 is rotatably connected, in which a vertical pipe 20 is slidably connected, a key groove is axially provided on the inner wall of the sleeve 19, and a key block 21 which matches the key groove is fixedly connected to the outer wall of the vertical pipe 20, so that the vertical pipe 20 can slide back and forth up and down in the sleeve 19, and when the sleeve 19 rotates, the vertical pipe 20 also rotates with the sleeve 19.

[0030] Specifically, the brush roller 15 is fixedly connected to the lower end of the vertical pipe 20, and the brush roller 15 includes a core shaft 22, which is coaxially fixedly connected to the lower end of the vertical pipe 20. A center hole 23 is provided at the center of the core shaft 22, and the vertical pipe 20 is correspondingly connected to the upper end of the center hole 23. A rotating pipe joint 24 is provided at the upper end of the vertical pipe 20. A plurality of through holes 25 that penetrate the core shaft 22 are provided on the inner wall of the center hole 23, and the outer ends of the through holes 25 are provided on the outer wall of the core shaft 22. An elastic airbag 26 is connected to the bottom of the core shaft 22. The elastic airbag 26 is an ordinary airbag with an elastic part added thereto, and a first liquid inlet 27 is provided on the top of the elastic airbag 26 and is correspondingly connected to the lower end of the center hole 23. The bottom and side of the elastic airbag 26 are both provided with a first liquid outlet 27. The core shaft 22 and the outer side of the elastic airbag 26 are wrapped with cotton cloth 28. The core shaft 22, the elastic airbag 26 and the cotton cloth 28 form a brush roller 15 with a cylindrical structure. During operation, the waterproofing solution can enter the vertical pipe 20 through the rotating pipe joint 24, and then enter the central hole 23 of the core shaft 22. The waterproofing solution then flows out of the core shaft 22 through each through hole 25. At the same time, the waterproofing solution also enters the elastic air bag 26 through the first liquid inlet, and flows out of the elastic air bag 26 through each first liquid outlet 27. Then, the waterproofing solution can be evenly immersed in the cotton cloth 28. When the brushing roller 15 rolls and brushes the side wall of the waterproof layer cutting position 46, the waterproofing solution can be evenly brushed on the side wall of the waterproof layer cutting position 46 through the cotton cloth 28.

[0031] In this embodiment, a washer 29 is fixedly mounted on the standpipe 20, and a second spring 30 mounted on the standpipe 20 is fixedly connected between the washer 29 and the base plate 16. A contact ring 32 mounted on the outer periphery of the standpipe 20 is fixedly connected to the upper side of the base plate 16 through a support rod 31, and the upper surface of the contact ring 32 is an inclined surface. A contact rod 33 is fixedly connected to the side wall of the standpipe 20, and the contact rod 33 is pressed on the upper surface of the contact ring 32. A power mechanism for driving the sleeve 19 to rotate is installed on the base plate 16. In this way, during the rotation of the sleeve 19, the standpipe 20 rotates with the sleeve 19, and the contact rod 33 moves along the upper surface of the contact ring 32. Since the upper surface of the contact ring 32 is an inclined surface, the standpipe 20 moves up and down with the contact rod 33. During the up and down movement of the vertical pipe 20, on the one hand, the brush roller 15 can be moved up and down, so that the brush roller 15 can better brush the side wall of the waterproof layer cutting position 46; on the other hand, the up and down movement of the vertical pipe 20 can make the core shaft 22 squeeze the elastic air bag 26, so that the waterproof solution in the elastic air bag 26 is squeezed into the cotton cloth 28 through each first liquid outlet 27, thereby improving the brushing effect on the side wall of the waterproof layer cutting position 46. Figure 1 and Figure 5 The contact ring 32 in the figure is shown incompletely to facilitate observation of the installation method of the contact ring 32.

[0032] Specifically, the power mechanism includes a motor mounting frame 34 and a first motor 35. The motor mounting frame 34 is fixed on the upper side of the base plate 16 and is located on one side of the contact ring 32. The first motor 35 is fixedly mounted on the motor mounting frame 34. The main shaft of the first motor 35 vertically penetrates and is rotatably connected to the base plate 16. A driving pulley is fixedly mounted on the main shaft of the first motor 35. A driven pulley is fixedly mounted on the outer circumference of the sleeve 19. The driving pulley and the driven pulley are connected by a belt 36. The driving belt 36 pulley, the driven belt 36 pulley and the belt 36 constitute a belt transmission mechanism. In other embodiments, the main shaft of the first motor 35 and the sleeve 19 can also be connected by a chain transmission mechanism or a gear set.

[0033] Specifically, the waterproof material brushing assembly includes a guide block 37, a vertical plate 38 and a brushing box 39. The lower side of the base plate 16 is provided with a guide groove arranged along the radial direction of the brush roller 15. The guide groove is not drawn in the figure. The guide groove adopts a dovetail groove. The guide block 37 is a dovetail block matching the dovetail groove. The guide block 37 is slidably connected in the guide groove. A cam 40 is fixedly installed at the lower end of the main shaft of the first motor 35. The cam 40 corresponds to the guide block 37 and is in tight contact. A third spring is fixedly connected between one side wall of the guide groove and the guide block 37. In this way, the first motor 35 generates a corresponding extrusion force on the guide block 37 through the cam 40 during the rotation process, and the guide block 37 can be reciprocated in the guide groove in cooperation with the elastic force of the third spring. The vertical plate 38 is welded and fixed to the lower side of the guide block 37, and the brush box 39 is fixedly connected to one side of the vertical plate 38 and is located on the upper side of the brush roller 15 away from the center of the swivel 3. A feed pipe 41 is provided on one side of the brush box 39, and a second liquid outlet is provided at the bottom of the brush box 39 and the side facing the brush roller 15. The outer side of the brush box 39 is wrapped with a brush cloth; under the action of the cam 40 and the third spring, the guide block 37 drives the vertical plate 38 and the brush box 39 to move horizontally back and forth, so that the brush box 39 intermittently collides with the upper side of the brush roller 15.

[0034] Specifically, the upper outer circumference of the core shaft 22 is provided with an arc groove along the circumferential direction, so that the upper outer circumference of the brush roller 15 forms an arc-shaped avoidance groove 42. Because at the waterproof layer cutting position 46 of the upper cover 45, the surface of the upper cover 45 and the waterproof layer cutting position 46 form a sharp corner portion, see Figure 6 In this way, the brush roller 15 makes point contact with the corner part, which may damage the cotton cloth 28 during long-term operation, thereby affecting the flow of the waterproof solution into other positions of the cotton cloth 28, resulting in poor brushing effect and short service life of the brush roller 15. Therefore, the purpose of setting the avoidance groove 42 is to avoid point contact between the brush roller 15 and the corner part, thereby improving the brushing effect and service life of the brush roller 15.

[0035] Specifically, the waterproof material liquid supply mechanism includes a waterproof solution tank 43 and a booster pump 44, which are installed on the upper side of the mobile vehicle 1, and the liquid outlet end of the waterproof solution tank 43 is connected to the liquid inlet end of the booster pump 44, and the liquid outlet end of the booster pump 44 is connected to the rotating pipe joint 24 at the upper end of the vertical pipe 20 and the feed pipe 41 on one side of the painting box 39 through corresponding hoses, and each hose is installed with a control valve.

[0036] When the present invention is used, refer to Figure 5 , and combined with Figure 1-Figure 4, the mobile vehicle 1 moves to the edge of the waterproof layer cutting position 46, and at the same time makes the base ring 2 located at the center of the waterproof layer cutting position 46, and drives the slider 6 to descend through the hydraulic cylinder 9, inserting the waterproof material rolling brush assembly into the waterproof layer cutting position 46, so that the brush roller 15 contacts the side wall of the waterproof layer cutting position 46 under the action of the first spring 18, and the second motor 10 drives the rotating ring 3 to rotate through the gear 11 gear ring 12, and the rotating ring 3 rotates to make the brush roller 15 move along the side wall of the waterproof layer cutting position 46. During the walking process, the sleeve 19 is driven to rotate by the first motor 35, and the sleeve 19 carries The movable vertical pipe 20 rotates together, thereby indirectly driving the coating roller 15 to rotate, realizing the self-rotation of the coating roller 15, and the coating roller 15 rolls and brushes the side wall of the waterproof layer cutting position 46 and is always in tight contact with the side wall of the waterproof layer cutting position 46, and the coating roller 15 can also rise and fall with the uneven surface of the side wall of the waterproof layer cutting position 46, avoiding missing coating, and improving the coating effect of the waterproof material. During the rotation of the coating roller 15, the coating roller 15 can also reciprocate up and down with the vertical pipe 20 under the action of the contact rod 33, the contact ring 32 and the second spring 30, further improving the coating effect. In addition, the waterproof material brushing assembly will drop to the surface of the upper cover 45, and the brushing box 39 will contact the upper surface of the waterproof layer cutting position 46. During the rolling brushing process of the brush roller 15, the first motor 35 will simultaneously drive the cam 40 to rotate, so that the brushing box 39 will move back and forth horizontally, so as to brush the waterproof material on the upper surface of the waterproof layer cutting position 46. In addition, the brushing box 39 will collide with the avoidance groove 42 of the brush roller 15 during the horizontal reciprocating movement. In this way, under the squeezing effect of the collision force, the waterproof solution in the brush cloth outside the brushing box 39 will fall off and penetrate downward along the outer wall of the brush roller 15, so that the waterproof solution in the cotton cloth 28 is more sufficient, further improving the brushing effect. During the entire brushing process, the booster pump 44 works to provide the waterproof solution in the waterproof solution tank 43 to the brush roller 15 and the brushing box 39 through the corresponding hoses.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
