[0026] two spray gun assemblies 403;

[0027] Two swing arm assemblies for respectively realizing the swing positioning of the two spray gun assemblies 403 in a horizontal plane, the two swing arm assemblies are symmetrically arranged on the same side of the lifting mechanism 2; the swing arm assembly comprises a main arm 401 and a sub-arm 402, one end of the main arm 401 is pivotally connected with one end of the sub-arm 402, the other end of the main arm 401 is pivotally connected with the lifting mechanism 2, the two spray gun assemblies 403 are respectively arranged on the opposite inner sides of the two sub-arms 402, the pivot axis between the main arm 401 and the sub-arm 402 is parallel to the pivot axis between the main arm 401 and the lifting mechanism 2; the sub-arm 402 has at least a first swing position and a second swing position relative to the main arm 401, when the two main arms 401 are swung to a state of a certain angle, and the two sub-arms 402 are both swung to the corresponding first swing position, the two spray gun assemblies 403 are respectively directed to a first set of two adjacent surfaces on the object to be sprayed, when the two sub-arms 402 are both swung to the corresponding second swing position, the two spray gun assemblies 403 are respectively directed to a second set of two adjacent surfaces on the object to be sprayed; wherein the object to be sprayed has a total of four surfaces to be sprayed, the first set of two adjacent surfaces refers to the two adjacent surfaces of the object to be sprayed, and the second set of two adjacent surfaces refers to the remaining two adjacent surfaces of the object to be sprayed.

[0028] Two first locking members 405 for respectively locking the two main arms 401 to the lifting mechanism 2 when the two main arms 401 are swung to a certain angle, which are respectively arranged between the two main arms 401 and the lifting mechanism 2.

[0029] Two first fastening members 404 for respectively locking the two sub-arms 402 to the corresponding first swing position or second swing position, which are respectively arranged between the corresponding main arm 401 and sub-arm 402.

[0030] Specifically, referring to Figure 1 The lifting mechanism 2 is arranged at the top of the mobile device 1 and used to drive the double-gun multi-surface spraying system 4 to ascend and descend; the double-spray gun design is adopted to simultaneously spray paint on two adjacent surfaces of the object to be sprayed, thereby improving the spraying efficiency; the two sub-arms 402 are further adjusted to make the two spray guns 4037 on the two sub-arms 402 respectively directed to the other two surfaces of the object to be sprayed, so that the multi-surface spraying of the object to be sprayed can be realized without moving the position of the overall device, and the operation is simple and the construction efficiency is high.

[0031] The certain angle is 90°, the main arm 401 and the corresponding sub-arm 402 are arranged one above the other, the first swing position of the sub-arm 402 is that the sub-arm 402 is swung to overlap with the corresponding main arm 401, and the second swing position of the sub-arm 402 is that the sub-arm 402 is swung to be perpendicular to the main arm 401 at the opposite inner side.

[0032] By designing the two main arms 401 at an angle of 90°, the angle of the two secondary arms 402 overlapping the two main arms 401 can also be 90°, which can adapt to the two vertical surfaces of the steel column to be sprayed, and by swinging to 90° between the secondary arm 402 and the corresponding main arm 401, the other two surfaces of the steel column can be adapted, which is beneficial to the spraying construction.

[0033] The double-gun multi-surface spraying system 4 further comprises two moving assemblies (not shown in the figure) respectively arranged on the two secondary arms 402, for driving the two spraying gun assemblies 403 to move along the axial direction of the corresponding secondary arms 402, respectively.

[0035] By starting the first motor to drive the first lead screw to rotate, the sliding block is driven to move along the length direction of the lead screw, and the corresponding spraying gun assembly 403 is driven to move along the length direction of the secondary arm 402, so as to adjust the position of the spraying gun assembly 403, which can realize horizontal reciprocating spraying construction on a certain area of the surface to be sprayed, and the spraying effect is good.

[0036] The spraying gun assembly 403 comprises a spraying gun 4037 and an adjusting assembly for adjusting the angle of the spraying gun 4037 in the vertical plane, the adjusting assembly being connected between the spraying gun 4037 and the moving assembly.

[0037] Specifically, the adjusting assembly comprises a second motor 4032 connected to the sliding block through a base plate 4031, and a connecting piece connected between the output shaft of the second motor 4032 and the spraying gun 4037, the second motor 4032 driving the connecting piece to deflect in the vertical plane, so as to drive the spraying gun 4037 to adjust the angle.

[0038] Further, the connecting piece comprises a first rotating arm 4033 fixedly connected to the output shaft of the second motor 4032 at the first end, a third motor 4034 fixed to the second end of the first rotating arm 4033, a second rotating arm 4035 fixedly connected to the output shaft of the third motor 4034 at the first end, and a locking device 4036 fixed to the second end of the second rotating arm 4035 and used for locking the spraying gun 4037.

[0041] Specifically, the first locking piece includes a first positioning pin, a third locking hole opened on the side of the block 4041 toward the auxiliary arm 402 overlapping with the corresponding main arm 401, and a fifth locking hole opened on the auxiliary arm 402, and when the first positioning pin passes through the fifth locking hole and is inserted into the third locking hole, the auxiliary arm 402 and the corresponding main arm 401 are fixed, and the auxiliary arm 402 overlaps with the corresponding main arm 401.
