Description

Technical Field

[0001] The invention belongs to the technical field of building decoration engineering, relates to an exterior wall painting technology, and specifically is an exterior wall painting device for building construction. Background Art

[0002] Exterior wall painting equipment for building construction refers to equipment used to efficiently and evenly paint the exterior walls of buildings during building construction, such as common sprayers, roller brushes, automatic painting robots, etc.

[0003] Among them, automatic painting robots are usually used for painting the exterior walls of high-rise buildings, replacing workers in high-altitude operations and reducing accidents involving workers in high-altitude operations. Existing automatic painting robots are mainly composed of a suspension assembly mounted on the roof, a spray assembly, and a control system. Workers can hang the automatic painting robot about 20 cm away from the exterior wall through the suspension assembly. The automatic painting robot moves up and down on the exterior wall surface along the steel rope through its internal motion system, and then the paint is evenly atomized and sprayed on the exterior wall through the spray assembly. The worker adjusts the suspension assembly on the roof so that the automatic painting robot can move horizontally and spray all-round at different positions of the exterior wall.

[0004] However, since automatic painting robots usually spray paint in a fan shape, when spraying at the edge of the wall, some atomized paint will splash. Due to the high wind speed at high altitudes, the splashed paint will float away, causing pollution to surrounding buildings or posing a safety hazard to pedestrians on the ground.

[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention is further described in detail in conjunction with the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. The technical solutions of the present invention are described in detail below in conjunction with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0018] Example 1 See also Figures 1 to 12 This embodiment proposes an exterior wall painting device for building construction, including a painting device body 1 and a moving seat 101 movably mounted on the painting device body 1; the moving seat 101 is connected to a driving motor and can move horizontally and reciprocatingly on the painting device body 1; a driving unit and a spray assembly are arranged in the painting device body 1; the driving unit and the spray assembly are both conventional structures of existing painting devices; the driving unit is used to drive the painting device body 1 to move along the steel rope as a whole; the spray assembly is used to spray the atomized paint on the surface of the exterior wall through the spray head 102. The spray head 102 is fixedly mounted on the moving seat 101, and one end of the spray head 102 is fixedly connected to a control mechanism for controlling the painting range.

[0019] Wherein, the control mechanism includes a fixed seat 201, which is a hollow box with an open structure at the front end. The nozzle 102 is located in the fixed seat 201. The first baffle 202 and the second baffle 203 are symmetrically connected to the front sides of the fixed seat 201 for rotation. The output end of the nozzle 102 is located between the first baffle 202 and the second baffle 203, and the lower ends of the first baffle 202 and the second baffle 203 are fixedly connected with a rotating gear 204. The rotating gear 204 is rotationally connected to the fixed seat 201, and the surface of the rotating gear 204 is meshed with a driving gear plate 205. The driving gear plate 205 slides linearly in the fixed seat 201, and the driving gear plate 205 is connected to a connecting member 3 for transmission; when the driving gear plate 205 is driven by the connecting member 3, it moves linearly and meshes to drive the rotating gear 204 to rotate a certain angle, thereby adjusting the angle between the first baffle 202 and the second baffle 203.

[0020] An electric telescopic rod 206 is installed in the movable seat 101, and a push rod 207 is fixedly connected to the output end of the electric telescopic rod 206, and a round rod 208 is slidably connected inside the push rod 207. A first spring 230 is fixedly connected between the round rod 208 and the push rod 207. An electrode contact point 231 is provided at the front end of the push rod 207 and the rear end of the round rod 208. The electrode contact point 231 is electrically connected to the spray assembly of the painting equipment body 1. When the two electrode contact points 231 are connected, an electrical signal is input to the spray assembly to prevent the spray assembly from continuing to spray paint on the exterior wall. One end of the round rod 208 away from the push rod 207 is rotatably connected to a round block 209, and three docking rods 210 are evenly and fixedly connected on the surface of the round block 209, and the angles of adjacent docking rods 210 are all 120 degrees. The ends of the three docking rods 210 are rotatably connected to rotating columns 229, and the three rotating columns 229 are used to fit and slide with the surface of the outer wall; in the normal spraying state, the painting equipment body 1 and the electric telescopic rod 206 work synchronously, the output end of the electric telescopic rod 206 pushes the push rod 207, and the rotating columns 229 on the two docking rods 210 contact the surface of the outer wall at the same time, and one end of the round rod 208 will drive the round block 209 and the docking rods 210 on its surface to fit tightly with the outer wall. When the moving seat 101 drives the electric telescopic rod 206 to move horizontally on the painting equipment body 1, the friction between the outer wall surface and the rotating column 229 drives the rotating column 229 to rotate in the docking rod 210. Under the reaction force of the outer wall, the round rod 208 will compress the first spring 230 and slide linearly in the push rod 207. At this time, the push rod 207 and the two electrode contact points 231 on the round rod 208 are in a separated state; the spraying assembly sprays paint on the outer wall.

[0021] The bottom of the round block 1 209 is fixedly connected with the round block 211. The surface of the round block 211 is provided with a semicircular arc groove 212. Two short slide bars 213 are symmetrically slidably connected in the semicircular arc groove 212. The short slide bars 213 are metal rods. The bottoms of the two short slide bars 213 are respectively slidably connected to a connecting rod 214. The two connecting rods 214 are located below the round block 211. The tops of the short slide bars 213 penetrate the outside of the connecting rod 214 and can enter the semicircular arc groove 212. The short slide bars 213 are connected to the semicircular arc groove 212. 3 makes a linear slide up and down in the connecting rod 214; a pulley 232 is rotatably connected between the two connecting rods 214, and a protruding short plate 233 is connected to one side of the pulley 232. The two connecting rods 214 are slidably connected to the sides close to each other with an extrusion plate 234. Two guide grooves 235 are symmetrically provided on the surface of the extrusion plate 234. One end of the extrusion plate 234 penetrates the outside of the connecting rod 214. The two guide grooves 235 are intermittently in sliding contact with the short slide rod 213 and the short plate 233 respectively.

[0022] Under normal working conditions, the forces on the two docking rods 210 in contact with the outer wall surface are balanced and offset, and the round block 1 209 and the round block 211 will not rotate. The short sliding rod 213 made of metal has a certain weight and can be stationary inside the connecting rod 214, and the two short sliding rods 213 are not in contact with the semicircular arc groove 212; when the mobile seat 101 drives the nozzle 102 and the electric telescopic rod 206 to start moving to one side, the rotating column 229 rolls on the wall surface. Since the pulley 232 is in contact with the painting equipment body 1 and is slidably connected, the pulley 232 rolls on the surface of the painting equipment body 1; at this time, the short plate 233 mounted on the surface of the pulley 232 rotates synchronously with the pulley 232. When the short plate 233 is pressed against a When the guide groove 235 on one side of the plate 234 contacts and squeezes, the short plate 233 pushes the squeeze plate 234 to slide linearly in the connecting rod 214, and the squeeze plate 234 pushes the short slide bar 213 to move upward in the connecting rod 214, so that the short slide bar 213 moves up and contacts with the semicircular groove 212; since the round block 211 does not rotate, when the short plate 233 no longer pushes the squeeze plate 234, the short slide bar 213 will fall into the connecting rod 214 again due to gravity; and if the round block 211 and the semicircular groove 212 rotate, when the short slide bar 213 moves up and enters the semicircular groove 212, the semicircular groove 212 will drive the short slide bar 213 to move, and the short slide bar 213 will drive the connecting rod 214 to move linearly. The connecting member 3 is connected between the connecting rod 214 and the driving gear plate 205; when the connecting rod 214 moves, the driving gear plate 205 is driven to move by the connecting member 3.

[0023] When the docking rod 210 and the rotating column 229 slide on the surface of the outer wall, when they encounter the edge of the outer wall or a recessed window position, the round rod 208 is pushed by the first spring 230 to closely adhere the two docking rods 210 to the wall. When one of the docking rods 210 falls and does not contact the wall, the round block 1 209 will rotate clockwise at one end of the round rod 208 by a certain angle, so that the round block 1 209 drives the round block 211 and its semicircular arc groove 212 to squeeze a short sliding rod 213, so that the short sliding rod 213 on this side drives the corresponding connecting rod 214 to push the connecting member 3, and the driving gear plate 205 drives the rotating gear 204 to rotate by a certain angle, thereby adjusting the angle of the first baffle 202 or the second baffle 203; reducing the opening of the first baffle 202 or the second baffle 203, thereby reducing the spraying range of the nozzle 102.

[0024] Specifically, the connecting member 3 includes a hydraulic rod 1 301 fixedly connected to one side of the driving gear plate 205, one end of the hydraulic rod 1 301 is fixedly connected to a piston 1 302, and the surface of the hydraulic rod 1 301 is covered with a hydraulic sleeve 1 303, and the piston 1 302 is slidably connected to the inner wall of the hydraulic sleeve 1 303, one end of the two connecting rods 214 are fixedly connected to a hydraulic rod 2 304, one end of the hydraulic rod 2 304 is fixedly connected to a piston 2 305, and the surface of the hydraulic rod 2 304 is covered with a hydraulic sleeve 2 306, and the piston 2 305 is slidably connected to the inner wall of the hydraulic sleeve 2 306, a hydraulic pipe 307 is provided between the hydraulic sleeve 1 303 and the hydraulic sleeve 2 306 on the same side, and oil is provided between the piston 1 302 and the piston 2 305 in the hydraulic pipe 307. When the docking rod 210 and the rotating column 229 slide on the surface of the outer wall, when the docking rod 210 and the rotating column 229 on one side are suspended in the air, the round block 211 and the semicircular arc groove 212 will be driven to rotate, so that the semicircular arc groove 212 squeezes one end of the short sliding rod 213, and pushes the connecting rod 214 and the corresponding hydraulic rod 2 304, so that the piston 2 305 moves in the hydraulic sleeve 2 306, so that the oil between the piston 1 302, the piston 2 305 and the hydraulic pipe 307 pushes the piston 1 302 to move in the hydraulic sleeve 1 303, so that the hydraulic rod 1 301 drives the driving gear plate 205 to engage and drive the rotating gear 204 to rotate a certain angle, thereby adjusting the inclination angle of the first baffle 202 or the second baffle 203 in the fixed seat 201; until the rotating column 229 of the other docking rod 210 is also suspended, indicating that the position of the spray head 102 is not the exterior wall surface. At this time, the round rod 208 is ejected from the push rod 207 under the action of the first spring 230, and the rear end of the round rod 208 docks with the electrode contact point 231 at the front end of the push rod 207, thereby controlling the spray assembly to stop spraying paint.

[0025] In order to detect the structure of the wall in advance, the docking rod 210 on one side of the embodiment is located in front of the nozzle 102; specifically, a through slot 215 is provided in the movable seat 101, and a T-shaped rod 216 is slidably connected in the through slot 215, and the through slot 215 is rectangular, and the T-shaped rod 216 is always located in the through slot 215; a pulley 217 is rotatably connected in the T-shaped rod 216, and a first gear 218 is fixedly connected to one side of the pulley 217, and a second gear 219 is meshed with the surface of the first gear 218, and the second gear 219 is meshed with the surface of the second gear 219. The center of the gear 219 is fixedly connected with a long rod 4, and one end of the long rod 4 away from the second gear 219 is fixedly connected with a third gear 220, and the third gear 220 is rotatably connected with the T-bar 216; the first tooth plate 221 and the second tooth plate 222 are slidably connected in the T-bar 216, and the first tooth plate 221 and the second tooth plate 222 are both meshed with the third gear 220; one end of the first tooth plate 221 and the second tooth plate 222 are fixedly connected with a moving rod 223, and one end of the moving rod 223 penetrates the outside of the T-bar 216. A sliding groove 224 is provided on the surface of the painting equipment body 1, and a rectangular rod 225 is slidably connected in the sliding groove 224. A cam 226 is rotatably connected to one side of the rectangular rod 225, and the cam 226 is in sliding contact with the two moving rods 223. An extrusion groove 227 is provided on the surface of the cam 226, and a guide rod 228 is fixedly connected in the moving seat 101, and the guide rod 228 is slidably connected with the extrusion groove 227.

[0026] When the moving seat 101 drives the T-bar 216 to move synchronously, the pulley 217 on one side of the T-bar 216 slides on the surface of the painting equipment body 1 and rotates in the T-bar 216, and synchronously drives the first gear 218 to rotate, and makes the second gear 219 and the third gear 220 rotate, so that the rotation direction of the third gear 220 is opposite to the rotation direction of the first gear 218 and the pulley 217. At this time, the rotation of the third gear 220 will engage and drive the first tooth plate 221 and the second tooth plate 222 to slide linearly in the fixed seat 201, and the linear motion directions of the two are opposite. At this time, the first tooth plate 221 drives the moving rod 223 to extend out of the outside of the T-bar 216, and the second tooth plate 222 and the moving rod 223 at one end of it are located in the T-bar 216.

[0027] When the movable seat 101 follows the nozzle 102 to move laterally in the painting equipment body 1, the guide rod 228 in the movable seat 101 moves simultaneously. At this time, the guide rod 228 will squeeze the extrusion groove 227 to drive the cam 226 to rotate 90 degrees on one side of the rectangular rod 225, so that the cam 226 squeezes and pushes a moving rod 223, so that the moving rod 223 and the T-shaped rod 216 move laterally in the through groove 215, so that the docking rod 210 is located in front of the movement direction of the nozzle 102, thereby detecting the exterior wall structure where the nozzle 102 sprays paint in advance, and reducing the paint splashing generated by the nozzle 102 at the edge of the exterior wall or the reserved window position of the exterior wall.

[0028] Example 2 This embodiment provides an exterior wall painting device for building construction. Except for the structure of the long rod 4 and the second gear 219, the rest of the structure is the same as that of the embodiment 1. The specific differences from the structure of the embodiment 1 are as follows: See also Fig.13 The second gear 219 is non-fixedly connected to the long rod 4, and a plurality of second springs 5 ​​are fixedly connected inside the long rod 4. One end of the second spring 5 is fixedly connected to a trapezoidal block 6, and a plurality of trapezoidal grooves 7 are provided on the surface of the second gear 219, and the trapezoidal grooves 7 are slidably connected to the trapezoidal block 6. When the moving seat 101 continuously drives the nozzle 102 to move laterally, the pulley 217 initially slides along the surface of the painting equipment body 1 and drives the second gear 219 and the third gear 220 to rotate through the meshing of the first gear 218, so that the first tooth plate 221 and the second tooth plate 222 are meshed and slide linearly on the surface of the third gear 220. When the first tooth plate 221 and the second tooth plate 222 move to the end of the T-bar 216, the first tooth plate 221 and the second tooth plate 222 stop moving linearly in the T-bar 216, and at this time, the pulley 217 continues to slide on the surface of the painting equipment body 1. The second gear 219 driven by the meshing of the first gear 218 on one side of the pulley 217 continues to rotate, and a relative movement is generated between the second gear 219 and the long rod 4, so that the trapezoidal groove 7 on one side of the second gear 219 and the trapezoidal block 6 on one side of the long rod 4 generate sliding friction, and the trapezoidal block 6 rotates in a circle on the surface of the second gear 219, the long rod 4 is stationary in the T-bar 216, and the second gear 219 continues to rotate in the T-bar 216; this improved structure can prevent the wear of the pulley 217; because if the second gear 219 is fixedly connected to the long rod 4, when the pulley 217 continues to slide on the surface of the outer wall, the third gear 220 stops rotating, which will increase the static friction generated by the pulley 217 on the surface of the outer wall, thereby increasing the wear of the pulley 217, which is not conducive to the painting equipment body 1 to carry out all-round spraying of paint on the outer wall of a high-rise building.

[0029] The basic working principle of the exterior wall painting device for building construction disclosed in Examples 1 and 2 is as follows: The worker first hangs the painting equipment body 1 on one side of the outer wall of a high-rise building through the existing conventional hanging assembly, and starts the driving unit in the painting equipment body 1 to make it move from the top of the building to the bottom of the building along the steel rope to complete a spray painting work. During the descent, at each height position, the painting equipment body 1 will drive the spray assembly to move the atomized paint through the moving seat 101, driving the nozzle 102 to spray the paint within a certain horizontal range on the outer wall surface, thereby evenly spraying the paint in this area.

[0030] When the work starts, the output end of the electric telescopic rod 206 pushes the push rod 207 and the round rod 208, so that the rotating column 229 slides along the surface of the outer wall, and the moving seat 101 drives the nozzle 102 to move horizontally on the painting equipment body 1. At this time, the pulley 232 moves in the same direction as the moving seat 101, and the pulley 232 and the short plate 233 rotate clockwise, and the short plate 233 and the guide groove 235 on the surface of the squeezing plate 234 on one side squeeze each other, so that the guide groove 235 on the other side of the squeezing plate 234 pushes the short sliding rod 213 to move upward and one end of it enters the semicircular groove 212. When the two docking rods 210 move to the edge of the outer wall and cause one docking rod 210 to be suspended, the round block 1 209 and the round block 211 rotate synchronously and drive the semicircular groove 212 to squeeze the short sliding rod 213, so that the short sliding rod 213 The rod 213 drives the connecting rod 214 to move linearly in the painting equipment body 1, and drives the driving gear plate 205 through the connecting member 3. The driving gear plate 205 drives the rotating gear 204 to rotate the first baffle 202 or the second baffle 203 to a certain angle, and reduce the opening angle of the first baffle 202 or the second baffle 203. Under the blocking effect of the first baffle 202 or the second baffle 203, the range of the spray head 102 spraying paint is further reduced; when the rotating column 229 of the other docking rod 210 is also suspended, it means that the spraying position of the spray head 102 is not the external wall surface. At this time, the round rod 208 is ejected from the push rod 207 under the action of the first spring 230, and the rear end of the round rod 208 is docked with the electrode contact point 231 at the front end of the push rod 207, thereby controlling the spray assembly to stop spraying paint. At the same time, the device uses the structure of the T-shaped rod 216 and the like to make the docking rod 210 on one side located in front of the spray head 102, so that the structure of the wall can be detected in advance. The improved structure of Example 2 can reduce the wear on pulley 217.
