DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0045] According to the concept of this application, Figures 1 to 12An embodiment of a brickwork maintenance spray device for construction is described below. Specifically, the brickwork maintenance spray device for construction is constructed as a split structure of a brickwork maintenance spray device for construction, which has three components: a transport box 1, a lifting assembly 4, and a spray device 7. The lifting assembly 4 drives the maintenance liquid to flow into the spray device 7, and drives the spray head 72 to slide upward during the flow, so that after the bricks 3 on the transport box 1 are piled up, the spray head can be aimed at the pores of the dry bricks 3, so as to facilitate the maintenance liquid to be sprayed into the inner wall of the pore of the brick, thereby increasing the contact area between the inner wall of the pore and the maintenance liquid.

[0046] Please refer to Figures 1 to 12 , a brick maintenance spraying device for construction, comprising: a transport box 1, a lifting assembly 4 and a spraying device 7;

[0047] A support plate 2 is slidably provided inside the transport box 1, and a brick 3 is placed on the upper end surface of the support plate 2;

[0048] A lifting assembly 4 is fixed at the center of the lower end of the support plate 2;

[0049] The lifting assembly 4 includes a support column 41, a support rod 42, a piston 43, a through hole 44 and a water pump 45. The support rod 42 is fixed to the lower end of the support plate 2, and the outer side of the support rod 42 is sealed with the support column 41. The piston 43 is fixed to the lower end of the support rod 42, and the side wall of the support column 41 is provided with a through hole 44, and the water outlet end of the water pump 45 passes through the inner side of the through hole 44.

[0050] A sealing assembly 8 is provided directly below the piston 43;

[0051] A sealing tube 5 is fixed to the lower end of the lifting assembly 4, and multiple ports of the sealing tube 5 are connected to multiple spray devices 7, and a one-way valve 6 is provided at the connection between the sealing tube 5 and the multiple spray devices 7;

[0052] The spray device 7 includes a spray hood 71, a spray head 72, a sealing plate 73 and a limit assembly 74, and multiple spray hoods 71 ​​are fixed to the outer wall of the transport box 1, a spray head 72 is slidably arranged on the inner side of the spray hood 71, and a sealing plate 73 is rotatably arranged at the lower end of the spray head 72, and a limit assembly 74 is fixed to the inner wall of the spray hood 71.

[0053] Before use, the curing liquid is injected into the spray hood 71. After the spray head 72 is inserted into the spray hood 71, the water level of the curing liquid is below the spray head 72. When in use, the staff removes the bricks 3 in the square body from the square body and places them on the transport box 1, and then places the bricks 3 on the upper end of the support plate 2 and fits the inner wall of the transport box 1, and opens the sealing assembly 8 to connect the support column 41 with the sealing tube 5. The support plate 2 is forced to slide downward along the inner wall of the transport box 1 by the pressure of the bricks 3, thereby driving the support rod 42 and the piston 43 to move downward along the support column 41, and the interior of the sealing tube 5 is pumped with curing liquid, and the piston 43 During the descent process, the curing liquid is pressed to flow around, and then flows into multiple spray hoods 71 ​​from multiple outlets of the sealing tube 5. At this time, the sealing plate 73 at the bottom of the spray head 72 is in a closed state, so that the curing liquid pushes the spray head 72 and the sealing plate 73 to slide upward. Due to the continuous accumulation of bricks 3, the position of the newly placed bricks 3 is gradually increased. If the spray position remains unchanged, the subsequently placed bricks 3 are not easily sprayed. After the height of the spray device 7 is higher than the bricks 3, it is difficult to spray into the horizontal pores. If the height of the spray device 7 is level with the pores where the bricks 3 are placed, when the next group of bricks 3 is placed, as the bricks 3 accumulate, The newly placed brick 3 is not flush with the height of the spray device 7. At the same time, in some embodiments, the spray device 7 is set to an adjustable state, but the worker needs to adjust it several times after each brick 3 is placed, which increases the workload of the worker and is inconvenient to use. When the spray head 72 moves to the working position, the sealing plate 73 cooperates with the limit assembly 74, and the sealing plate 73 is opened. At this time, the curing liquid inside the spray cover 71 enters the spray head 72 and then sprays into the interior of the transport box 1. When the brick 3 is placed on the transport box 1, the curing liquid is pressed into the spray device 7 by the lifting assembly 4, which increases the water flow speed and pressure in the sealing tube 5. Thereby, the curing liquid has a certain water pressure when it is sprayed outward, so that when the curing liquid is sprayed on the brick 3, it can wash away the dust and residue on the outside of the brick 3, thereby cleaning the brick 3, thereby reducing the subsequent operation steps, and because the water pressure of the curing liquid sprayed from the spray head 72 is relatively high, its penetrability is relatively strong, so that when multiple bricks 3 are arranged side by side, the pores of the bricks 3 overlap, and the curing liquid can still be sprayed onto the inner wall of the pore, and the pores of the concrete porous bricks are maintained, thereby reducing cracks and deformation caused by drying and temperature changes, and improving the overall stability of the structure, and then the curing liquid flows into the bottom of the transport box 1.

[0054] When the piston 43 moves downward to the upper end of the sealing assembly 8, the curing liquid in the spray hood 71 stops flowing upward, and the direction of the one-way valve 6 is such that the sealing tube 5 can flow into the spray hood 71 and prevent the curing liquid in the spray hood 71 from flowing back. The one-way valve 6 between the spray hood 71 and the sealing tube 5 prevents the curing liquid in the spray hood 71 from flowing back, and the curing liquid in the spray head 72 moves downward under the influence of gravity and forces the sealing plate 73 to rotate and close. Before the next brick 3 is placed, the sealing assembly 8 is driven to form a sealed state between the support column 41 and the sealing tube 5. At this time, the water pump 45 is started to pump the curing liquid at the bottom of the transport box 1 into the sealing hood 81 and push the piston 43. And the support plate 2 moves upward until the position of the support plate 2 is reset. Since the position of the support plate 2 is close to the upper end surface of the transport box 1, it is convenient for the staff to put in the bricks 3, reducing the bending degree of the waist and back when the staff bends down, which is beneficial to reduce the damage to the waist and back. The bricks 3 stacked in a square body are split and placed on the transport box 1 for spraying and curing. When the bricks 3 in the middle of the square body are placed on the transport box 1, the influence of the obstruction by other bricks 3 and the problem of limited maintenance area are reduced. In addition, the bricks 3 are sprayed and maintained during the process of transporting the bricks 3 to the room through the device, thereby saving the time for spraying and maintenance.

[0055] A plurality of sleeves 21 are fixed to the lower end surface of the support plate 2, and support springs 22 are arranged on the outer sides of the plurality of sleeves 21. When in use, the plurality of support springs 22 and the sleeves 21 provide upward support to the support plate 2, and improve the stability of the up and down movement of the support plate 2. When the bricks 3 are placed on the support plate 2, the pressure on the support plate 2 increases, and relative displacement may occur between the support plate 2 and the transport box 1. The support springs 22 can compensate for this displacement, and maintain the correct position and clearance of the mechanical parts.

[0056] The side wall of the support plate 2 is provided with a plurality of grooves 201, and the inner wall of the transport box 1 is fixed with a plurality of guide rods 101, and the positions of the guide rods 101 match the positions of the grooves 201. When in use, the plurality of guide rods 101 are respectively inserted into the corresponding grooves 201, and when the support plate 2 slides up and down, the grooves 201 on the support plate 2 slide up and down along the guide rods 101, and the movement path of the support plate 2 is limited by the plurality of guide rods 101, so as to avoid the support plate 2 from still being able to slide up and down in the vertical direction when the force on the support plate 2 is uneven, thereby further improving the stability of the movement of the support plate 2.

[0057] The sealing assembly 8 includes a sealing cover 81 and an electric telescopic rod 82 . The inner side of the support column 41 is sealed with the sealing cover 81 , and a plurality of water filtering holes 811 are penetrated through the upper end of the sealing cover 81 . The electric telescopic rod 82 is fixed to the inner side of the sealing cover 81 .

[0058] When in use, after the staff puts the brick 3 on the support plate 2, the staff stays away from the transport box 1. Since there is maintenance liquid in the support column 41 for supporting the piston 43 to move upward, the maintenance liquid in the support column 41 enters the sealing cover 81 through the water filter hole 811, and the electric telescopic rod 82 is started. The electric telescopic rod 82 drives the sealing cover 81 to move upward until the sealing cover 81 is separated from the sealing groove 51, so that the support column 41 and the sealing tube 5 form a connecting structure, and then the maintenance liquid enters the spray device 7 along the sealing tube 5, and then is sprayed on the brick 3 through the spray device 7, forming intermittent spraying.

[0059] In order to increase the frequency of spraying, in one case, the spray device 7 is directly connected to the water pump 45 so that the spray device 7 can circulate and spray water for a long time. However, when the staff puts the dry bricks 3 in the transport box 1, if the spray device 7 continues to spray water, the water sprayed when the staff bends down to put the bricks in will affect the staff's line of sight. At the same time, the water in the spray will also be sprayed on the staff, causing discomfort to the staff. The intermittent spraying in this solution can reduce the impact of the spray device 7 on the staff during the transportation process.

[0060] A sealing groove 51 is formed at the central bottom of the sealing tube 5 , and the shape of the sealing groove 51 matches the lower end surface of the sealing cover 81 .

[0061] When the spraying is finished, the electric telescopic rod 82 is started, and the electric telescopic rod 82 drives the sealing cover 81 to move downward until the bottom surface of the sealing cover 81 is inserted into the sealing groove 51, thereby preventing the maintenance liquid in the support column 41 from flowing into the sealing tube 5. When the water pump 45 pumps the maintenance liquid into the support column 41, the maintenance liquid is pressed by the piston 43, the support plate 2 and the brick 3, so that the maintenance liquid will apply pressure to the side wall of the outer sealing cover 81, which is easy to cause deformation at the bottom edge of the sealing cover 81, resulting in poor sealing. Of course, in some cases, by setting an electromagnetic valve between the sealing tube 5 and the support column 41, and setting a gravity sensor on the support plate 2, the flow of the liquid in the support column 41 is controlled by opening and closing the gravity sensor electromagnetic valve. However, due to the complex use of the construction site, when the staff directly throws the brick 3 into the transport box 1 to save effort, the impact force between the single brick 3 and the support plate 2 is large, which makes the pressure sensor prone to misjudgment, which is not conducive to use.

[0062] The sealing plate 73 includes a rotating shaft 731, a baffle 732 and a magnet 733. The lower end surface of the spray head 72 is rotatably connected to the rotating shaft 731, and the baffle 732 is fixed to the outer side of the rotating shaft 731, and magnets 733 tangent to the rotating shaft 731 are fixed at both ends of the rotating shaft 731. Two groups of sealing plates 73 are symmetrically arranged about the vertical center of gravity line of the spray head 72, and the two groups of sealing plates 73 are sealed and matched. When the two sets of sealing plates 73 are in a horizontal state, the edges of the two baffles 732 fit together. At this time, the sealing plates 73 are in a closed state, which is used to reduce the flow of water through the sealing plates 73. At this time, the side walls of the two magnets 733 fit together with the side walls of the slide groove 711, so that when the maintenance liquid pushes the sealing plates 73 upward, the magnets 733 and the slide groove 711 are against each other, thereby limiting the large-angle rotation of the rotating shaft 731, reducing the outflow of the maintenance liquid in the spray head 72, so that before the spray head 72 moves to the working position, the two sealing plates 73 can maintain a relatively closed state, which is conducive to the maintenance liquid pushing the spray head 72 to rise. When the brick 3 is raised, the spray head 72 is aligned with the position of the brick 3, so as to facilitate spraying to the pores of the brick 3.

[0063] The inner wall of the spray hood 71 is provided with a plurality of slide grooves 711, and the width of the slide grooves 711 is equal to the diameter of the rotating shaft 731, so that the rotating shaft 731 and the magnet 733 are limited in position during the sliding process in the slide grooves 711, and since the maintenance liquid exerts an upward thrust on the baffle 732, the rotating shaft 731 and the baffle 732 tend to rotate upward along the rotating shaft 731, and the magnet 733 is against the slide grooves 711, and the slide grooves 711 have a circumferential restriction on the rotating shaft 731, so that the sealing plate 73 remains closed.

[0064] like Figures 8 to 10 The limiting component 74 includes a movable groove 741, an iron sheet 742 and an arc groove 743, and a plurality of movable grooves 741 are equidistantly provided on the side of the slide groove 711, an iron sheet 742 is slidably provided on the inner side of the movable groove 741, and an arc groove 743 is provided on the side wall of the movable groove 741, and the moving path of the iron sheet 742 is the same as the path of the arc groove 743.

[0065] When in use, when the sealing plate 73 moves to the movable groove 741, the magnet 733 fits with the iron sheet 742, and the maintenance liquid in the spray hood 71 pushes up the baffle 732. At the same time, because the magnet 733 moves to the movable groove 741, the supporting force of the slide groove 711 on the magnet 733 is weakened, so that the baffle 732 rotates upward with the rotating shaft 731 as the center, so that the two sealing plates 73 are opened upward, thereby forming an open and closed state. During the rotation of the rotating shaft 731, the side wall of the magnet 733 fits with the side of the iron sheet 742 through magnetic force. At this time, most of the maintenance liquid passes through the sealing plate 73, thereby reducing the thrust on the sealing plate 73. When the spraying is completed, the maintenance liquid in the sealing tube 5 no longer enters The magnet 733 and the iron sheet 742 are attracted to each other, so that the iron sheet 742 slides along the arc groove 743 and moves to the end of the arc groove 743. At this time, the iron sheet 742 fits the side wall of the slide groove 711 and blocks the side wall of the movable groove 741, so that the side of the slide groove 711 and the side of the iron sheet 742 are in the same horizontal plane. At this time, the magnetic force between the magnet 733 and the iron sheet 742 stops the spray head 72 at this position to reduce the distance that the spray head 72 slides downward under the force of gravity.

[0066] An elastic protrusion 7431 is provided on the inner side of the arc groove 743, and a limiting rod 7421 is fixed on one side of the iron sheet 742 close to the arc groove 743. The elastic protrusion 7431 is located at the end of the arc groove 743. When the iron sheet 742 is in a vertical state, the limiting rod 7421 is just stuck in the elastic protrusion 7431. At the same time, the upper and lower end surfaces of the iron sheet 742 are both in contact with the side wall of the movable groove 741, so as to further fix the position of the iron sheet 742, which is beneficial to improve the stability of the movement of the iron sheet 742.

[0067] A protrusion 7311 is fixed to the side wall of the rotating shaft 731. When the spray head 72 moves to the highest point, the staff can directly press the spray head 72 downward to separate the magnet 733 from the iron sheet 742. During the sliding process of the magnet 733 along the side wall of the slide groove 711, the protrusion 7311 squeezes the iron sheet 742 in a vertical state, so that the limiting rod 7421 on the iron sheet 742 is separated from the elastic protrusion 7431 to facilitate the next movement of the sealing plate 73 to this position, thereby reducing the resistance of the iron sheet 742 to the magnet 733, so that when the sealing plate 73 moves to the iron sheet 742, the sealing plate 73 can be opened, so that when the spray head 72 reaches the movable groove 741, it can automatically open and close. The distance between adjacent movable grooves 741 is flush with the height of each stacked brick 3, so that when the bricks 3 are stacked, the spray head 72 can be flush with the newly placed bricks 3, which is convenient for spraying and maintenance.

[0068] The following is a further description of a bricklaying maintenance spray device for construction provided by the present invention in conjunction with the accompanying drawings and implementation modes.

[0069] Before use, inject maintenance liquid into the spray hood 71 and the bottom of the transport box 1, pump the maintenance liquid into the sealing tube 5 through the water pump 45, insert the spray head 72 into the spray hood 71, until the rotating shaft 731 moves to the lower end of the slide groove 711, and close the sealing assembly 8. When in use, the staff removes the bricks 3 in the square body from the square body and places them on the upper end surface of the support plate 2 on the transport box 1. The staff drives the electric telescopic rod 82 to extend upward and drives the sealing hood 81 to move upward to open the sealing assembly 8, so that the support column 41 is connected with the sealing tube 5. The support plate 2 is forced to slide downward along the guide rod 101 by the pressure of the brick 3, driving the support rod 42 and the piston 43 to move downward. During the descent of the piston 43, the maintenance liquid is pressed to flow around, and then flows into multiple spray hoods 71 ​​from multiple outlets of the sealing tube 5. At this time, the spray head The sealing plate 73 at the bottom of 72 is in a closed state, so that the curing liquid pushes the spray head 72 and the sealing plate 73 to slide upward. When the sealing plate 73 moves to the movable groove 741, the rotating shaft 731 rotates and causes the two sets of sealing plates 73 to change from a closed state to an open and closed state, so that the curing liquid in the spray cover 71 enters the spray head 72 and is sprayed toward the transport box 1. After the spraying is completed, the electric telescopic rod 82 contracts downward, so that the bottom of the sealing cover 81 is engaged in the groove 201, so that the support column 41 is in a sealed state, and then the maintenance liquid at the bottom of the transport box 1 is pumped into the support column 41 through the water pump 45, and the piston 43, the support rod 42 and the support plate 2 are pushed upward by the maintenance liquid, so that it is convenient for the staff to put in the bricks 3. When the bricks 3 on one side are piled up to the moving height, the spray head 72 is pressed to the bottom of the slide groove 711 again.
