[0002] Cylindrical steel formwork is a kind of prefabricated steel formwork widely used in civil engineering construction, especially suitable for the casting of concrete structures. They usually have standardized sizes, shapes and connection methods to improve construction efficiency, ensure project quality, reduce construction costs and speed up construction progress.

[0003] In order to facilitate the demoulding of concrete and improve the surface quality of the formed components, a release agent needs to be applied to the inner surface of the cylindrical steel formwork before use.

[0025] Example 1 See also Figures 1 to 6 The present invention provides a device for applying a release agent to a curved template, comprising a walking mechanism 1 that moves on a curved butt rib 101 at one end of a curved template 100, a guide rail 2 that is detachably arranged on the walking mechanism 1, the guide rail 2 corresponding to the length of the curved template 100, and a brushing unit 3 for applying a release agent to the curved template 100 that is slidably arranged on the guide rail 2; For arc templates 100 of different lengths, the guide rails 2 of corresponding lengths can be replaced accordingly, and can be flexibly applied to the release agent painting work of these arc templates 100 of different sizes and lengths, which greatly broadens the application scope of the device and enables it to meet the actual needs of various engineering projects; It also includes a liquid supply mechanism 4 for supplying liquid to the painting unit 3, and the liquid supply mechanism 4 is connected to the painting unit 3 through a pipeline.

[0026] When the device is in use, the walking mechanism 1 is first installed on the arc-shaped butt rib 101 at one end of the arc-shaped template 100, and the guide rail 2 corresponding to the length of the arc-shaped template 100 is installed on the walking mechanism 1, so that the guide rail 2 can cover the entire area where the release agent needs to be applied, providing a guide track for the movement of the application unit 3; When the brushing unit 3 is working, the release agent is transported to the brushing unit 3 through the liquid supply mechanism 4. When the brushing unit 3 moves back and forth, the release agent is evenly applied to the inner wall of the curved template 100. The walking mechanism 1 continuously changes its position on the curved template 100, and gradually realizes the brushing work of the inner wall of the entire curved template 100.

[0027] The guide rail 2 includes two parallel slide rails 5, on which the painting unit 3 is slidably arranged, and the upper ends of the two guide rails 2 are detachably connected to the walking mechanism 1; The lower ends of the two guide rails 2 are fixedly connected by a fixed plate, and a reciprocating screw rod 6 is rotatably arranged in the middle of the fixed plate, and the reciprocating screw rod 6 drives the painting unit 3 to reciprocate along the axis of the slide rail 5; A driving motor 7 is fixedly arranged on the traveling mechanism 1 , and a motor shaft of the driving motor 7 is detachably connected to an upper end portion of the reciprocating screw rod 6 .

[0028] Furthermore, a slot is provided at the upper end of the reciprocating screw 6, and an insertion rod is fixedly provided on the motor shaft of the driving motor 7, and the insertion rod is plugged into the slot. The driving motor 7 drives the reciprocating screw 6 to rotate, thereby realizing the reciprocating movement of the brushing unit 3 along the axis of the slide rail 5. When the brushing unit 3 moves, the release agent is evenly applied to the inner wall of the arc template 100.

[0029] The painting unit 3 includes a slider 8 slidably arranged on two slide rails 5, a notch is provided in the middle of the slider 8, the notch is sleeved on the outside of the reciprocating screw 6, a guide pin is rotatably arranged in the notch, and the guide pin slides in the thread groove of the reciprocating screw 6; The reciprocating screw is a screw that can make the slider 8 reciprocate without changing the direction of rotation of the main shaft. The reciprocating screw 6 is a form of a three-dimensional cam pair, which is represented by two thread grooves with the same pitch and opposite rotation directions, and the two ends are connected by a transition curve. Through the rotation of the screw, the side of the spiral groove pushes the slider 8 placed in the spiral groove to make axial reciprocating motion; through the sliding of the guide pin in the thread groove, the reciprocating screw 6 drives the slider 8 to make linear reciprocating motion when rotating; Two sets of painting brush assemblies 9 are fixedly arranged on the slider 8, and each set of painting brush assemblies 9 includes two outer rods 10 fixedly arranged on the slider 8, an inner rod 11 is slidably arranged in each outer rod 10, a spring is arranged between the inner rod 11 and the outer rod 10, and one end of the two inner rods 11 is fixedly connected by a fixing frame 12; The spring can make the brush 13 always stick to the inner wall of the curved template 100, ensuring a good brushing effect in areas with different curvatures and different flatnesses; A brush 13 is fixedly arranged on the fixing frame 12; The brush 13 comprises an inner cylinder rotatably connected to the fixing frame 12, the inner cylinder is hollow inside and bristles are fixedly arranged on the outer wall, and a plurality of through holes are provided on the side wall of the inner cylinder; A joint 14 is rotatably provided at one end of the inner tube connected to the fixing frame 12 , and the joint 14 is connected to the liquid supply mechanism 4 through a pipeline.

[0030] The inner cylinder is connected to the pipeline from the liquid supply mechanism 4 through the joint 14, so that the demoulding agent in the liquid supply mechanism 4 can be smoothly transported to the inside of the inner cylinder. As the slider 8 drives the brush assembly 9 to reciprocate along the slide rail 5, the brush 13 is tightly fitted with the surface of the arc template 100. The demoulding agent transported by the liquid supply mechanism 4 enters the inner cylinder through the pipeline and the joint 14, and then penetrates into the bristles through a number of through holes opened on the side wall of the inner cylinder. After the bristles are dipped in the demoulding agent, the demoulding agent is evenly applied to the surface of the arc template 100 under the action of the relative friction between the brush 13 and the surface of the arc template 100, thereby completing the brushing work of the arc template 100.

[0031] The walking mechanism 1 includes a frame 15, on which a roller 16 is rotatably provided, and two swing arms 17 are rotatably provided on one side of the frame 15 close to the roller 16, and a walking wheel 19 is rotatably provided at the movable end of each swing arm 17, and a boss is fixedly provided at each end of each walking wheel 19, and the movable ends of the two swing arms 17 are connected by an adjusting assembly 18; A driven sprocket 20 is coaxially fixedly disposed on each traveling wheel 19; A driving sprocket 21 is rotatably disposed on the frame 15 , and the driving sprocket 21 is connected to the driven sprocket 20 via a chain 22 .

[0032] The rotating end of the swing arm 17 is rotatably provided with a guide wheel, and the chain 22 passes around the guide wheel; A tensioning wheel is arranged on the frame 15 located in the middle of the two swing arms 17, and the chain 22 passes around the tensioning wheel. The tensioning wheel can make the chain 22 always mesh with the driving sprocket 21 and the two driven sprockets 20, avoiding the phenomenon that the chain 22 and the driven sprocket 20 are separated after the position of the swing arm 17 is adjusted.

[0033] A driven gear 23 is fixedly arranged on the driving sprocket 21; A driving gear 24 is rotatably arranged in the middle of the slider 8, and the driving gear 24 is axially slidable and radially fixed with the reciprocating screw rod 6; When the driving gear 24 is in contact with the driven gear 23 , the driving gear 24 and the driven gear 23 are meshed with each other.

[0034] When the reciprocating screw rod 6 drives the slider 8 to move to the upper end of the slide rail 5, the driving gear 24 is meshed with the driven gear 23. When the reciprocating screw rod 6 rotates, it drives the driving gear 24 to rotate. When the driving gear 24 rotates, it drives the driven gear 23 to rotate. The driven gear 23 then drives the driving sprocket 21 to rotate. Under the action of the chain 22, the two driven sprockets 20 are driven to rotate, and then the travel wheel 19 is driven to rotate. The travel wheel 19 rolls on the arc-shaped docking rib 101, driving the entire frame 15 to move along the arc-shaped docking rib 101, so that the entire brushing device moves along the arc-shaped docking rib 101, which is convenient for brushing the inner wall of the entire arc-shaped template 100; The length of the driven gear 23 is greater than that of the driving gear 24, providing a larger meshing range, so that the walking mechanism 1 can move a certain distance on the arc-shaped docking rib 101; When the reciprocating screw 6 drives the slider 8 to move downward, the driving gear 24 is still engaged with the driven gear 23. As the slider 8 continues to move, the driving gear 24 is separated from the driven gear 23. At this time, the position of the walking mechanism 1 on the arc template 100 is relatively fixed, which is convenient for applying the release agent to the arc template 100.

[0035] A sleeve is fixedly disposed on both sides of the frame 15 , and each sleeve is plugged into one of the slide rails 5 . A threaded hole is provided on the side wall of the sleeve, and a locking knob 25 is threadedly connected in the threaded hole.

[0036] By plugging the slide rail 5 into the sleeves on both sides of the frame 15, the operation is simple and direct. After the slide rail 5 is inserted into the sleeve, tighten the locking knob 25, and the end of the knob will press against the outer wall of the slide rail 5. Through this extrusion effect, the slide rail 5 is firmly fixed in the sleeve. Even if the device is running for a long time or is subjected to vibration or other external forces, it can be ensured that the slide rail 5 will not accidentally fall out of the sleeve, thereby maintaining the integrity of the entire coating device structure and the reliability of the connection between the components, ensuring that the release agent coating work can be carried out continuously and stably.

[0037] The adjustment assembly 18 includes adjustment cylinders 26 rotatably connected to the swing arms 17 , internal threads are arranged on the inner walls of the adjustment cylinders 26 , a bidirectional screw 27 is arranged between the two adjustment cylinders 26 , and threads at both ends of the bidirectional screw 27 are threadedly connected to the adjustment cylinders 26 .

[0038] When the walking mechanism 1 needs to be installed on the curved template 100, the bidirectional screw 27 is first rotated to make the two swing arms 17 approach each other. At this time, the distance between the two walking wheels 19 and the roller 16 is large, which is convenient for the installation of the walking mechanism 1. Since a boss is respectively arranged at both ends of the walking wheel 19, the boss can be stuck on both sides of the curved docking rib 101. The trajectory of the walking wheel 19 is restricted by the boss, which effectively prevents the walking wheel 19 from deviating to the left or right and derailing during the movement, ensuring that the walking wheel 19 always rolls along the predetermined route of the curved docking rib 101, so that the entire walking mechanism 1 and the components such as the brushing unit 3 installed thereon can maintain a stable travel trajectory, which is very critical for accurately controlling the brushing position of the brushing unit 3 on the surface of the curved template 100; Then, the bidirectional screw 27 is rotated in the opposite direction to make the outer walls of the two traveling wheels 19 closely contact with the outer walls of the arc-shaped docking ribs 101 , and the outer wall of the roller 16 closely contact with the inner wall of the arc-shaped template 100 , so that the traveling mechanism 1 is installed on the arc-shaped template 100 .

[0039] The liquid supply unit includes a cart 28 with wheels, on which a liquid storage tank 29 is fixedly arranged, and the liquid storage tank 29 is filled with a release agent; A liquid supply pump 30 is also provided on the trolley 28 . The inlet end of the liquid supply pump 30 extends into the liquid storage tank 29 , and the outlet end is connected to the joint 14 through a pipeline.

[0040] First, push the cart 28 to one side of the curved template 100, place it steadily, check and fill the release agent, then connect the pipeline of the liquid supply pump 30 and the brushing unit 3. When supplying liquid, start the liquid supply pump 30 and adjust the flow rate according to the brushing demand. The release agent enters the inner cylinder through the pipeline and the joint 14, and then penetrates into the bristles through a number of through holes opened on the side wall of the inner cylinder. After the bristles are dipped in the release agent, the release agent is evenly applied to the surface of the curved template 100 under the action of the brush 13 moving with the slider 8 and the relative friction between itself and the surface of the curved template 100, thereby completing the brushing work of the curved template 100.

[0041] Furthermore, a placement rack is provided on the trolley 28, and after the walking mechanism 1 and the guide rail 2 are used, they can be placed on the placement rack for easy centralized storage and management, saving manpower and handling costs, improving the continuity and overall efficiency of the construction process, and ensuring that all components of the painting device are always in an orderly circulation state.

[0042] When the present invention is used, the device is first installed on the arc-shaped butt joint rib 101 at one end of the arc-shaped template 100, and the guide rail 2 corresponding to the length of the arc-shaped template 100 is installed on the walking mechanism 1, so that the guide rail 2 can cover the entire area where the release agent needs to be applied, providing a guide track for the movement of the application unit 3; When the brushing unit 3 is working, the release agent is transported to the brushing unit 3 through the liquid supply mechanism 4. When the brushing unit 3 moves back and forth, the release agent is evenly applied to the inner wall of the curved template 100. The walking mechanism 1 continuously changes its position on the curved template 100, and gradually realizes the brushing work of the inner wall of the entire curved template 100.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
