Description
Technical Field
[0001] This utility model belongs to the field of concrete release agent spraying technology, specifically a heat-insulating concrete release agent uniform spraying device. Background Technology
[0002] Thermal insulation concrete release agent is a special release material designed specifically for concrete construction. It combines the functions of release and thermal insulation, and has important application value in construction, bridge and road projects.
[0003] When pouring concrete components, formwork is needed to restrict the shape and size of the concrete components. To facilitate demolding, a heat-insulating concrete release agent needs to be applied to the formwork. For ease of operation, this step of applying the release agent is usually done before the formwork is installed. Currently, there are some release agent spraying devices on the market that can automatically spray the formwork surface. However, these spraying devices require the formwork to be placed flat on the operating table. When a large amount of release agent is sprayed onto the formwork, it is easy for some areas of the formwork surface to have too much release agent, resulting in an excessively thick film in some areas after the release agent forms a film.
[0004] Therefore, this utility model provides a device for uniformly spraying a heat-insulating concrete release agent. Utility Model Content

[0009] Preferably, elastic film sleeves are fixedly connected to both sides of the movable seat; the other end of the elastic film sleeve is fixedly connected to the side wall of the spraying frame; the lead screw is located inside the elastic film sleeve; through the above structure, the occurrence of impurities falling on the lead screw and hindering the movement of the movable seat can be reduced, and the occurrence of motor overload due to excessive resistance can be reduced.
[0010] Preferably, a partition is fixedly connected to the middle of the spraying frame; the partition is disposed through the movable seat; multiple support rings are fixedly connected to the middle of the elastic film sleeve; the partition is located inside the elastic film sleeve and the support rings, and is located above the lead screw; through the above structure, the wear of the elastic film sleeve can be reduced, and thus the occurrence of impurities falling on the lead screw after the elastic film sleeve is worn through can be reduced.
[0011] Preferably, the spraying frame has multiple pedals fixed to its middle section; the upper surface of the pedals is treated with anti-slip material; with the above structure, when it is necessary to operate the transmission components at a higher position, one can step on the pedals to climb, thus eliminating the need to find external objects as footrests, thereby improving the ease of use of the lifting device.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figures 1 to 5 As shown in the figure, a uniform spraying device for heat-insulating concrete release agent according to an embodiment of the present invention includes a spraying frame 1; a motor 12 is fixedly connected to the top side wall of the spraying frame 1; a lead screw 13 is fixedly connected to the output end of the motor 12; a movable seat 14 is threadedly connected to the middle of the lead screw 13; the movable seat 14 is slidably connected to the top of the spraying frame 1; a winding and unwinding mechanism 15 is installed on the top of the movable seat 14; a connecting rope 16 is installed in the middle of the winding and unwinding mechanism 15; a pair of fixed rods 17 are fixedly connected to the side wall of the spraying frame 1; a movable rod 18 is slidably connected to the middle of the pair of fixed rods 17; a spraying mechanism 19 is slidably connected to the middle of the movable rod 18; a transmission assembly is installed between the movable seat 14, the connecting rope 16, the movable rod 18, and the spraying mechanism 19; during operation, the template to be sprayed with release agent is placed against the inclined side of the spraying frame 1, and release agent is injected into the spraying mechanism 19 through a supply pipe or by direct injection. The release agent can be sprayed... The mechanism 19 sprays out in an atomized state. The operation of the motor 12 drives the lead screw 13 to rotate. When the lead screw 13 rotates, the moving seat 14 slides. When the moving seat 14 slides, it drives the moving rod 18 to move through the transmission component, so that the spraying mechanism 19 can move horizontally. The operation of the winding and unwinding mechanism 15 winds up and down the connecting rope 16. The transmission component drives the spraying mechanism 19 to move up and down along the moving rod 18. Through the operation of the motor 12 and the winding and unwinding mechanism 15, the spraying mechanism 19 can spray the release agent relatively evenly on one side of the template from top to bottom. If more release agent is sprayed, it will flow down the side of the template. Through the above structure, the concrete template can be leaned against the spraying frame 1 at a certain angle for the release agent spraying. The excess release agent can slide off the template by itself. The operation of the motor 12 and the winding and unwinding mechanism 15 can be used to automatically spray the template with release agent.
[0025] like Figures 1 to 5As shown, the transmission assembly includes a connecting joint 2, a fastening sleeve 21, and a limiting plate 22; the connecting joint 2 is rotatably connected to the side wall of the movable seat 14; the middle part of the connecting joint 2 can overlap the middle part of the upper fixed rod 17 and restrict the movable rod 18 inside; the fastening sleeve 21 is threadedly connected to the middle part of the connecting rope 16 near the end; the limiting plate 22 is fixed to the end of the connecting rope 16; the spraying mechanism 19 has a connecting groove 23 in the middle; during operation, the spraying is driven by the operation of the motor 12 and the winding and unwinding mechanism 15. When mechanism 19 moves automatically, the overlapping joint 2 is rotated to overlap the fixed rod 17, and the top of the moving rod 18 is positioned between the two ends of the overlapping joint 2. This causes the moving rod 18 to move along with the moving seat 14 and the overlapping joint 2. Then, the middle part of the connecting rope 16 is moved into the connecting groove 23, and the fastening nut 21 is rotated. The fastening nut 21 and the limiting plate 22 are used to squeeze the middle part of the spraying mechanism 19. The increased friction makes it difficult for the fastening nut 21 and the limiting plate 22 to engage with the spraying mechanism 19. Separation is achieved, thus completing the connection between the connecting rope 16 and the spraying mechanism 19, allowing the spraying mechanism 19 to move up and down as the connecting rope 16 is wound and unwound. When the motor 12 or the winding mechanism 15 malfunctions, causing the moving seat 14 to be unable to move normally or the winding mechanism 15 to be unable to wound and unwound the connecting rope 16 normally, the spraying mechanism 19 cannot move freely due to the limitation of the transmission components. In this case, the above operation can be reversed to rotate the overlap 2 away from the fixed rod 17, and the connecting rope 16 will no longer be connected to the spraying mechanism 19. At this time, the position of the spraying mechanism 19 can be manually adjusted by holding the handle in the middle of the spraying mechanism 19, thereby changing the automatic operation to manual operation. Through the above structure, when the device components malfunction and make it difficult to perform automatic spraying operations, the spraying mechanism 19 can be easily separated from the transmission components, so that the spraying mechanism 19 can be manually moved and the spraying operation can continue, reducing the impact of the failure of some components of the device on the time of the template release agent spraying operation.
[0026] like Figures 4 to 5As shown, a groove 3 is provided in the middle of the spraying mechanism 19; a movable frame 31 is slidably connected to the middle of the groove 3; a rotating plate 32 is rotatably connected to the middle of the movable frame 31 via a torsion spring; multiple limiting grooves 33 are provided on the side wall of the movable rod 18; a baffle 34 is fixedly connected to the side wall of the groove 3; a limiting hook 35 is fixedly connected to the top of the side of the rotating plate 32 facing the limiting groove 33; during operation, when the spraying mechanism 19 is connected to the transmission assembly and automatic spraying is required through the operation of the motor 12 and the take-up and unwinding mechanism 15, the position of the rotating plate 32 is adjusted so that the bottom end of the rotating plate 32 moves to the side of the baffle 34. At this time, the rotating plate 32 is blocked by the baffle 34 and is difficult to rotate due to the torsion spring, so that the limiting hook 35 is difficult to fall into the limiting groove 33 and affect the movement of the spraying mechanism 19. After the moving component separates from the spraying mechanism 19, the rotating plate 32 is moved to the height where it is disengaged from the baffle 34. At this time, the rotating plate 32 will rotate under the action of the torsion spring, and the limiting hook 35 will fall into the limiting groove 33. At this time, the rotating plate 32 and the moving frame 31 can hardly descend further, thus fixing the spraying mechanism 19 at the corresponding height, so as to spray the template surface at the same height. By rotating the rotating plate 32 to disengage the limiting hook 35 from the limiting groove 33, the spraying mechanism 19 can be lowered again. With the above structure, when manually operating the spraying mechanism 19 to spray the template with release agent, the spraying mechanism 19 can be easily stopped at the corresponding height, so that the operator does not need to continuously lift the spraying mechanism 19, reducing the operator's physical exertion and improving the ease of use of the device.
[0027] like Figures 1 to 3 As shown, elastic film sleeves 4 are fixed to both sides of the movable seat 14; the other end of the elastic film sleeve 4 is fixed to the side wall of the spray frame 1; the lead screw 13 is located inside the elastic film sleeve 4; during operation, as the movable seat 14 moves, a pair of elastic film sleeves 4 will extend and retract, continuously blocking external impurities, making it difficult for external impurities to fall on the lead screw 13, reducing the occurrence of impurities entering between the lead screw 13 and the movable seat 14, which would increase the moving resistance of the movable seat 14. Through the above structure, the occurrence of impurities falling on the lead screw 13 and hindering the movement of the movable seat 14 can be reduced, and the occurrence of excessive resistance causing the motor 12 to overload can be reduced.
[0028] like Figures 1 to 3As shown, a partition 5 is fixedly connected to the middle of the spraying frame 1; the partition 5 is disposed through the movable seat 14; multiple support rings 51 are fixedly connected to the middle of the elastic film sleeve 4; the partition 5 is located inside the elastic film sleeve 4 and the support rings 51, and is located above the lead screw 13; during operation, when the elastic film sleeve 4 contracts, the support rings 51 will fall on the partition 5 and slide, thereby making it difficult for the contracted elastic film sleeve 4 to contact the lead screw 13 and the partition 5, thereby reducing the wear of the elastic film sleeve 4. Through the above structure, the wear of the elastic film sleeve 4 can be reduced, and thus the occurrence of impurities falling on the lead screw 13 after the elastic film sleeve 4 is worn through can be reduced.
[0029] like Figure 1 As shown, multiple pedals 6 are fixed to the middle of the spraying rack 1; the upper surface of the pedals 6 is treated with anti-slip material; when it is necessary to operate the transmission components at a higher position, one can step on the pedals 6 to climb up, thus eliminating the need to find external objects as footrests, improving the ease of use of the lifting device.
[0030] like Figure 1 As shown, multiple rollers 7 are rotatably connected to the side wall of the pedal 6; multiple rotating rollers 71 are rotatably connected to the bottom of the side wall of the spray frame 1; after the spraying of a template is completed, it is not necessary to adjust the position of the moving rod 18. The template can be easily removed by simply sliding it laterally. At this time, the multiple rollers 7 and rotating rollers 71 will rotate and reduce the friction force on the template. Through the above structure, when the template is removed by lateral movement, the friction force on the template can be reduced, thereby reducing the operating resistance and improving the ease of use of the device.
[0031] During operation, the template to be coated with release agent is placed against the inclined side of the spraying frame 1, and the release agent is injected into the spraying mechanism 19 through a supply pipe or direct injection. The release agent is sprayed out in an atomized state through the spraying mechanism 19. The operation of the motor 12 drives the lead screw 13 to rotate. When the lead screw 13 rotates, the moving seat 14 slides. When the moving seat 14 slides, it drives the moving rod 18 to move through the transmission component, thereby enabling the spraying mechanism 19 to move horizontally. The operation of the take-up and unwinding mechanism 15 winds up and unwinds the connecting rope 16, and the transmission component drives the spraying mechanism 19 to move up and down along the moving rod 18. Thus, through the operation of the motor 12 and the take-up and unwinding mechanism 15, the spraying mechanism 19 can move horizontally. 9. Apply release agent evenly to one side of the template from top to bottom. If too much release agent is sprayed, it will flow down the side of the template. When the spraying mechanism 19 needs to be moved automatically by the operation of the motor 12 and the winding and unwinding mechanism 15, rotate the overlapping joint 2 to place the overlapping joint 2 on the fixed rod 17, and place the top of the moving rod 18 between the two ends of the overlapping joint 2, so that the moving rod 18 moves with the moving seat 14 and the overlapping joint 2. Then, move the middle part of the connecting rope 16 into the connecting groove 23, and rotate the fastening nut 21 to squeeze the middle part of the spraying mechanism 19 with the fastening nut 21 and the limiting plate 22. The increased friction makes it difficult for the fastening nut 21 and the limiting plate 22 to separate from the spraying mechanism 19, thus completing the connection of the rope 16. The connection between the 6 and the spraying mechanism 19 allows the spraying mechanism 19 to move up and down as the connecting rope 16 is wound and unwound. If the motor 12 or the winding mechanism 15 malfunctions, causing the moving seat 14 to malfunction or the winding mechanism 15 to fail to properly wind and unwound the connecting rope 16, the spraying mechanism 19 cannot move freely due to the limitations of the transmission components. In this situation, the above operation can be reversed to rotate the overlap 2 away from the fixed rod 17, thus disconnecting the connecting rope 16 from the spraying mechanism 19. At this point, the position of the spraying mechanism 19 can be manually adjusted by holding the handle in the middle of the spraying mechanism 19, thereby changing the automatic operation to manual operation. This is necessary when connecting the spraying mechanism 19 to the transmission components and requiring the motor... When automatic spraying is performed by the operation of the unwinding and rewinding mechanism 12 and the winding mechanism 15, the position of the rotating plate 32 is adjusted so that the bottom end of the rotating plate 32 moves to the side of the baffle 34. At this time, the rotating plate 32 is blocked by the baffle 34 and is difficult to rotate due to the torsion spring. Thus, the limiting hook 35 is difficult to fall into the limiting groove 33, which affects the movement of the spraying mechanism 19. After the transmission component is separated from the spraying mechanism 19, the rotating plate 32 is moved to a height away from the baffle 34. At this time, the rotating plate 32 will rotate under the action of the torsion spring, and the limiting hook 35 will fall into the limiting groove 33. At this time, the rotating plate 32 and the moving frame 31 are difficult to descend further, thus fixing the spraying mechanism 19 at the corresponding height, so as to spray the template surface at the same height.By rotating the rotating plate 32 to disengage the limiting hook 35 from the limiting groove 33, the spraying mechanism 19 can be lowered again. As the moving seat 14 moves, a pair of elastic film sleeves 4 will extend and retract, continuously blocking external impurities, making it difficult for them to fall onto the lead screw 13. This reduces the likelihood of impurities entering between the lead screw 13 and the moving seat 14, causing increased resistance to movement of the moving seat 14. When the elastic film sleeves 4 retract, the support ring 51 will fall onto the partition plate 5 and slide, making it difficult for the retracted elastic film sleeves 4 to contact the lead screw 13 and the partition plate 5, thus reducing wear on the elastic film sleeves 4. After spraying a template, there is no need to adjust the position of the moving rod 18; the template can be easily removed by simply sliding it laterally. At this time, multiple rollers 7 and rotating rollers 71 will rotate, reducing the friction on the template.
