Description

Technical Field

[0001] The invention belongs to the technical field of spraying equipment, and in particular relates to an intelligently adjustable multi-surface spraying machine. Background Art

[0002] Paint refers to the material applied to the surface of the object to be protected or decorated, which can form a continuous film that is firmly attached to the coated object and has a certain strength. Sometimes, all four sides of the object to be sprayed need to be sprayed with paint, such as spraying fire-retardant paint on the four sides of a four-sided steel column indoors to ensure the fire resistance of the steel column. At present, the spraying of fire-retardant paint on the steel column on-site mostly adopts the workers standing on a mobile scaffolding and holding a spray gun to spray the fire-retardant paint on the spraying surface. The degree of automation is low, and the workers are in close contact with polluted dust for a long time, which brings multiple occupational diseases such as pneumoconiosis and harms the health of the workers. In addition, a single nozzle is used, the spraying efficiency is low, and the scaffolding needs to be moved to the other side after spraying one side of the steel column, which is troublesome to operate and affects the construction efficiency. In addition, the workers climb up and down, which poses a safety hazard. Therefore, we propose an intelligent adjustable multi-surface sprayer to solve the above problems. Summary of the invention

When the swing position of the main arm relative to the lifting mechanism is locked, when the auxiliary arm swings to the first swing position, the spray gun assembly faces one of the two adjacent surfaces of the object to be sprayed, and when the auxiliary arm swings to the second swing position, the spray gun assembly faces the other of the two adjacent surfaces of the object to be sprayed.

[0012] A further improvement of the intelligently adjustable multi-surface spraying machine of the present invention is that the spray gun assembly is movably mounted on the auxiliary arm along the axial direction of the auxiliary arm through a moving assembly.

[0017] A further improvement of the intelligent adjustable multi-surface sprayer of the present invention is that the lifting mechanism includes a multi-stage lifting assembly, a fixed frame fixed to the top of the mobile device and used to support the multi-stage lifting assembly, and a connecting seat arranged on the multi-stage lifting assembly and pivotally connected to the main arm. The multi-stage lifting assembly drives the swing arm assembly to adjust the height, so as to realize driving the spray gun assembly to adjust the height.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention adopts a double spray gun design, which can spray paint on two adjacent sides of the object to be sprayed at the same time, thereby improving the spraying efficiency; and then by adjusting the rotation of the two auxiliary arms, the two spray guns on the two auxiliary arms are respectively directed to the other two sides of the object to be sprayed, so that the object to be sprayed can be fully sprayed without moving the position of the entire equipment, and the operation is simple and the construction efficiency is high; the spray gun is driven to rise and fall by the lifting mechanism to realize the spraying of the object to be sprayed from high to low.

DETAILED DESCRIPTION

[0034] In order to solve the problems of low automation, low spraying efficiency, low construction efficiency and potential safety hazards in manual spraying, the present invention provides an intelligent adjustable multi-surface spraying machine. The intelligent adjustable multi-surface spraying machine is further described below with specific embodiments and accompanying drawings.

[0035] See also Figures 1 to 13 As shown, an intelligent adjustable multi-surface spraying machine comprises:

[0036] Spray gun assembly 403;

[0037] Mobile device 1;

[0038] A lifting mechanism 2 is disposed on the top of the mobile device 1 and is used to adjust the height of the spray gun assembly 403;

[0039] A swing arm assembly 4 for realizing horizontal swing of the spray gun assembly 403 on the lifting mechanism 2, the swing arm assembly 4 comprising a main arm 401 and a secondary arm 402, one end of the main arm 401 is pivotally connected to one end of the secondary arm 402, the other end of the main arm 401 is pivotally connected to the lifting mechanism 2, and the spray gun assembly 403 is mounted on one side of the secondary arm 402, wherein the pivot axis between the main arm 401 and the secondary arm 402 is parallel to the pivot axis between the main arm 401 and the lifting mechanism 2;

[0040] A first locking member 405 for locking the swing position of the main arm 401 relative to the lifting mechanism 2, disposed between the main arm 401 and the lifting mechanism 2;

[0041] The first fastener 404 for locking the swing position of the auxiliary arm 402 relative to the main arm 401 is arranged between the main arm 401 and the auxiliary arm 402; wherein,

[0042] The auxiliary arm 402 has at least a first swing position and a second swing position relative to the main arm 401. When the swing position of the main arm 401 relative to the lifting mechanism 2 is locked, when the auxiliary arm 402 swings to the first swing position, the spray gun assembly 403 faces one of the two adjacent surfaces of the object to be sprayed. When the auxiliary arm 402 swings to the second swing position, the spray gun assembly 403 faces the other of the two adjacent surfaces of the object to be sprayed.

[0043] Specifically, the mobile device 1 can be an AGV trolley, and a 3D camera 10 is arranged on the lifting mechanism 2. The mobile device 1 has an automatic navigation function, which can realize the automatic positioning of the trolley and navigate to the vicinity of the next object to be sprayed; in conjunction with the built-in 3D camera 10, the precise positioning between the trolley and the surface of the steel column can be realized through visual scanning, and the entire spraying machine is relatively intelligent;

[0044] Further, there are two swing arm assemblies 4, and the two swing arm assemblies 4 are symmetrically arranged on the same side of the lifting mechanism 2, there are two spray gun assemblies 403, and the two spray gun assemblies 403 are respectively installed on the opposite inner sides of the two auxiliary arms 402, the main arm 401 and the auxiliary arm 402 are arranged one above and one below, and when the auxiliary arm 402 swings to overlap with the corresponding main arm 401, it is the first swing position of the auxiliary arm 402, and when the auxiliary arm 402 swings to the relative inner side and is perpendicular to the main arm 401, it is the second swing position of the auxiliary arm 402;

[0045] There are two first locking members 405, which are respectively arranged between the two main arms 401 and the lifting mechanism 2, and are used to lock the two main arms 401 to the lifting mechanism 2 when the two main arms 401 swing to be perpendicular to each other;

[0046] There are two first fasteners 404 , which are respectively disposed between the main arm 401 and the auxiliary arm 402 in the two swing arm assemblies 4 , and are used to lock the two auxiliary arms 402 to the corresponding first swing position or the second swing position.

[0047] By adopting a double spray gun design, paint can be sprayed on two adjacent sides of the object to be sprayed at the same time, thereby improving the spraying efficiency; and by adjusting the rotation of the two auxiliary arms 402, the two spray gun assemblies 403 on the two auxiliary arms 402 are respectively directed to the other two sides of the object to be sprayed, so that the object to be sprayed can be fully sprayed without moving the position of the entire equipment, and the operation is simple and the construction efficiency is high; the spray gun assembly 403 is driven to rise and fall by the lifting mechanism 2 to realize spraying of the object to be sprayed from high to low. The entire equipment is mechanized and automated, which greatly improves the construction efficiency compared to manual work and reduces the contact time between operators and polluted dust.

[0048] The spray gun assembly 403 is mounted on the auxiliary arm 402 so as to be movable along the axial direction of the auxiliary arm 402 via a moving assembly (not shown in the figure).

[0049] Specifically, the moving assembly includes a sixth motor fixed on the auxiliary arm 402, a third lead screw rotatably connected to the auxiliary arm 402 and fixedly connected to the output shaft of the sixth motor, and a slider threadedly sleeved on the outside of the third lead screw and connected to the spray gun assembly 403.

[0050] By starting the sixth motor to drive the third lead screw to rotate, the slider moves along the length direction of the third lead screw, so that the spray gun assembly 403 moves along the length direction of the corresponding auxiliary arm 402, which is beneficial for the spray gun assembly to reciprocate spray the surface to be sprayed.

[0051] The spray gun assembly 403 includes a spray gun 4037 and an adjustment assembly for adjusting the angle of the spray gun 4037 on a vertical plane, and the adjustment assembly is connected between the spray gun 4037 and the slider.

[0052] The adjustment component includes a first motor 4032 connected to the slider through a base plate 4031 and a connecting piece connected between the output shaft of the first motor 4032 and the spray gun 4037. The first motor 4032 drives the connecting piece to deflect on the vertical plane to drive the spray gun 4037 to adjust the angle.

[0053] Specifically, the connecting member includes a first rotating arm 4033 whose first end is connected and fixed to the output shaft of the first motor 4032, a second motor 4034 fixed to the second end of the first rotating arm 4033, a second rotating arm 4035 whose first end is connected and fixed to the output shaft of the second motor 4034, and a locking device 4036 fixed to the second end of the second rotating arm 4035 and used to lock the spray gun 4037.

[0054] Furthermore, the spray gun 4037 can be connected to an external paint storage tank through a hose to allow the spray gun 4037 to perform normal spraying operations;

[0055] By driving the first rotating arm 4033 to rotate with the first motor 4032 and driving the second rotating arm 4035 to rotate with the second motor 4034, the spray gun 4037 can be driven to adjust the angle of the spraying surface of the object to be sprayed, for example, upward / downward, so that the spray gun 4037 can fit the spraying surface more closely, reduce splashing during spraying, and increase the utilization rate of raw materials.

[0056] In this embodiment, the locking device 4036 can be opened / closed. When the locking device 4036 is opened, the spray gun 4037 can be removed from the locking device 4036 and can be used to adjust the direction of the spray gun 4037. For example, the two auxiliary arms 402 are respectively stacked with the corresponding two main arms 401, and one side of the two auxiliary arms 402 is respectively perpendicular to the relative inner sides of the corresponding two main arms 401. When these two states are converted to each other, the spray gun 4037 needs to be removed to adjust the spray gun 4037 to the surface to be sprayed; the spray gun 4037 can be locked by closing the locking device 4036.

[0057] Among them, the first fastener 404 includes a right-angled block 4041 fixed to the inner side of one end of the main arm 401 close to the auxiliary arm 402, a first locking member for locking the auxiliary arm 402 swung to the first swing position with a right-angled side of the block 4041, and a second locking member for locking the auxiliary arm 402 swung to the second swing position with another right-angled side of the block 4041.

[0058] Specifically, the first locking member includes a first positioning bolt, a third locking hole opened on the side of the stop block 4041 facing the auxiliary arm 402 overlapping with the corresponding main arm 401, and a fifth locking hole opened on the auxiliary arm 402. When the first positioning bolt passes through the fifth locking hole and is inserted into the third locking hole, the auxiliary arm 402 is fixed to the corresponding main arm 401, and the auxiliary arm 402 overlaps with the corresponding main arm 401.

[0059] The second locking member includes a first positioning bolt, a fourth locking hole 4042 and a fifth locking hole which are opened on the side of the stop block 4041 facing the auxiliary arm 402 which is perpendicular to the corresponding main arm 401. When the first positioning bolt passes through the fifth locking hole and is inserted into the fourth locking hole 4042, the auxiliary arm 402 is fixed to the corresponding main arm 401, and the relative inner side of the auxiliary arm 402 is perpendicular to the corresponding main arm 401.

[0060] Furthermore, the block 4041 is a right-angled triangle block, and the third locking hole and the fourth locking hole 4042 are respectively arranged on the two right-angled sides of the block 4041; when the auxiliary arm 402 rotates to abut against a right-angled side of the block 4041 toward the main arm 401, the third locking hole is aligned with the fifth locking hole; when the auxiliary arm 402 rotates to abut against another right-angled side of the block 4041, the fourth locking hole 4042 is aligned with the fifth locking hole; the third locking hole, the fourth locking hole 4042 and the fifth locking hole are all screw holes; the first positioning bolt is a bolt.

[0061] By adopting the above design and using the first fastener 404 to fix the main arm 401 and the auxiliary arm 402, it can be ensured that the connection is relatively stable during the actual spraying process.

[0062] Among them, the sprayer also includes a positioning plate 5, and the two main arms 401 are respectively pivoted to the tops of the opposite ends of the positioning plate 5. The first locking member 405 includes a second fixing bolt, a connecting piece 4051 fixed on the corresponding main arm 401, a first locking hole 4052 penetrating along the thickness direction of the connecting piece 4051, and a second locking hole opened at the top of the positioning plate 5. The second fixing bolt passes through the first locking hole 4052 and is inserted into the second locking hole to fix the main arm 401 to the positioning plate 5.

[0063] Specifically, the sprayer also includes two third locking parts, which are used to fix the two main arms 401 to the positioning plate 5, and the two main arms 401 are parallel to each other after being fixed; the third locking part includes a third fixing bolt, a first locking hole and a sixth locking hole opened at the top of the positioning plate, and the third fixing bolt passes through the first locking hole 4052 and is inserted into the sixth locking hole to fix the main arm 401 to the positioning plate 5, and make the two main arms 401 parallel to each other after being fixed.

[0064] Furthermore, the second fixing bolt and the third fixing bolt are both bolts, and the first locking hole 4052, the second locking hole and the sixth locking hole are all screw holes; through the fixation of the first locking member 405, the two main arms 401 that are vertical relative to the inner side can be positioned firmly, which is beneficial to the stable spraying of the spray gun 4037; through the fixation of the third locking member, the two main arms 401 that are parallel to each other can be positioned firmly, which is beneficial to the contraction of the intelligent adjustment multi-surface sprayer of the present invention when it is not in working state.

[0065] The lifting mechanism 2 includes a multi-stage lifting assembly, a fixing frame 201 fixed on the top of the mobile device 1 and used to support the multi-stage lifting assembly, and a connecting seat 3 arranged on the multi-stage lifting assembly and connected to the positioning plate 5. The swing arm assembly 4 is driven by the multi-stage lifting assembly to adjust the height, so as to drive the spray gun assembly 403 to adjust the height.

[0066] Specifically, the 3D camera 10 is fixed on the top of the fixing frame 201. The AGV trolley cooperates with the built-in 3D camera 10, and through visual scanning, accurate positioning between the trolley and the surface of the steel column can be achieved.

[0067] The multi-stage lifting assembly includes a first lifting frame 202 slidably connected to the outside of the fixed frame 201, a second lifting frame 203 slidably connected to the outside of the first lifting frame 202, a first driving device arranged on the fixed frame 201 and used to drive the first lifting frame 202 to adjust its height, a second driving device 209 used to drive the second lifting frame 203 to adjust its height, and a third driving device 208 arranged on the second lifting frame 203 and used to drive the connecting seat 3 to adjust its height;

[0068] The first driving device includes a third motor 206 fixed to the lower part of the fixing frame 201, a rotating shaft 205 connected to the upper part of the fixing frame 201, a first gear set fixed to the output shaft of the third motor 206, a second gear set fixed to the end of the rotating shaft 205, a chain set sleeved outside the first gear set and the second gear set, and a docking seat fixed to the outer side of the chain set, and the lower part of the first lifting frame 202 is connected and fixed to the docking seat;

[0069] Specifically, the third motor 206 is a double-axle extension motor, the first gear set includes two first gears 207 respectively fixed on the output shafts at both ends of the double-axle extension motor, the second gear set includes two second gears respectively fixed on both ends of the rotating shaft 205, the two first gears 207 correspond to the two second gears respectively, the chain set includes two chains 204, and the two chains 204 are respectively sleeved on the corresponding two first gears 207 and the second gear. By driving at both ends, the first lifting frame 202 can be lifted and lowered more stably, and the first level height adjustment can be achieved;

[0070] The second driving device 209 includes a fixed block fixed to the upper part of the first lifting frame 202, a first threaded opening penetrating along the thickness direction of the fixed block 2092, a fourth motor 2093 fixed to the upper part of the second lifting frame 203, a first lead screw 2091 rotatably connected to the second lifting frame 203, a third gear 2094 fixed to the output shaft of the fourth motor 2093, and a fourth gear 2095 fixed to one end of the first lead screw 2091 close to the fourth motor 2093 and meshing with the third gear 2094. The first lead screw 2091 passes through the first threaded opening and is screwed to the first threaded opening. The third gear 2094 and the fourth gear 2095 are driven to rotate by starting the fourth motor 2093 to drive the first lead screw 2091 to rotate. Since the fixed block 2092 is fixed to the upper part of the first lifting frame 202, rotating the first lead screw 2091 will drive the second lifting frame 203 to move up and down to achieve secondary height adjustment.

[0071] Specifically, the third driving device 208 includes a fifth motor 2081 fixed to the lower part of the second lifting frame 203, a fifth gear 2082 fixed to the output shaft of the fifth motor 2081, a second lead screw 2084 rotatably connected to the second lifting frame 203, a moving block 2085 threadedly sleeved on the outside of the second lead screw 2084, and a sixth gear 2083 fixed on the second lead screw 2084 and meshing with the fifth gear 2082, and the outside of the moving block 2085 is connected to the connecting seat 3; by starting the fifth motor 2081 to drive the fifth gear 2082 and the sixth gear 2083 to rotate, so as to drive the second lead screw 2084 to rotate, thereby driving the moving block 2085 to move up and down, and then the entire swing arm assembly 4 can be driven to move up and down through the connecting seat 3 and the positioning plate 5, and then the spray gun assembly 403 can be driven to move up and down, realizing three-level height adjustment and multi-level fully automatic lifting adjustment, which is suitable for long-distance precise lifting, and the entire adjustment process is automated and intelligent.

[0072] The connecting seat 3 includes a frame 302 and a positioning seat 301 . The positioning seat 301 is connected to one end of the frame 302 and connected to the positioning plate 5 . The other end of the frame 302 is connected to the third driving device 208 .

[0073] The components connected by the positioning seat 301 and the frame 302 are respectively located on both sides of the entire device, so that the weight can be evenly distributed on both sides, which greatly reduces the risk of equipment instability caused by uneven mass distribution on the same side and greatly improves the balance of the entire device.

[0074] Among them, the first lifting frame 202 is square and the first lifting frame 202 is slidably mounted on the outside of the fixed frame 201. The sprayer also includes a balancing mechanism, which includes four telescopic rods 7 respectively fixed to the four corners of the lower part of the first lifting frame 202 for supporting the indoor roof.

[0075] By adopting a square first lifting frame 202 that is slidably sleeved on the outside of the fixed frame 201, the stability of the lifting of the first lifting frame 202 can be ensured;

[0076] Specifically, the balancing mechanism also includes four elastic members 8 respectively fixed to the top of the four telescopic rods 7 and four gaskets 9 respectively fixed to the top of the four elastic members 8. The telescopic rods 7 can be hydraulic rods and cylinders, and the elastic members 8 can be springs. The four gaskets 9 are made to contact with the indoor roof by extending the four telescopic rods 7, thereby enhancing the stability of the entire device and preventing overturning. The design of the elastic member 8 has a certain degree of elasticity and can adaptively adjust the extended length of the telescopic rod 7 according to the height of the top plane. The pneumatic / hydraulic push ensures that there is sufficient thrust to reach the indoor roof, thereby enhancing the balance of the entire device.

[0077] The positioning plate 5 is foldably connected to the upper portion of the positioning seat 301 , and the positioning plate 5 can be folded to a horizontal / vertical shape. The sprayer further includes a second locking member 406 for fixing the horizontal positioning plate 5 to the positioning seat 301 .

[0078] Specifically, the second locking member 406 includes a fourth fixing bolt, a fixing ear 4061 fixedly connected to the end of the positioning plate 5 away from the main arm 401, a seventh locking hole 4062 penetrating along the thickness direction of the fixing ear 4061, and an eighth locking hole opened at the top of the positioning seat 301. The fourth fixing bolt passes through the seventh locking hole 4062 and is inserted into the eighth locking hole to fix the horizontal positioning plate 5 to the positioning seat 301.

[0079] By adjusting the positioning plate 5 to be horizontal and fixing it, it is convenient to unfold the swing arm assembly 4 for construction; adjusting the positioning plate 5 to be vertical is conducive to the contraction of the swing arm assembly 4.

[0080] The spraying machine further comprises two second driving members 6 for respectively controlling the two main arms 401 to move the positioning plate 5 from a vertical state / horizontal state to a horizontal state / vertical state.

[0081] Specifically, the second driving member 6 includes a cylinder, a push block movably hinged to the cylinder output shaft and fixedly connected to the bottom of the corresponding main arm 401, and a movable seat connected to one end of the cylinder away from the output shaft and fixed to the lower part of the positioning seat 301, the movable seat includes a connecting member, a first connecting block fixed to the lower part of the positioning seat, a second connecting block fixed to the bottom of the cylinder, a first movable groove opened at one end of the connecting member and vertically arranged, and a second movable groove opened at the other end of the connecting member and horizontally arranged, the first connecting block is movably hinged to the first movable groove, and the second connecting block is movably hinged to the second movable groove;

[0082] The push block is driven by the cylinder to push the corresponding main arm 401 horizontally / drive and pull down the corresponding main arm 401 to be vertical. By adopting the above design, it is convenient to unfold the swing arm assembly 4 when working, and to retract the swing arm assembly 4 when not working.

[0083] A construction method for intelligently adjusting a multi-surface spraying machine comprises the following steps:

[0084] S1.
