Description

Technical Field

[0002] Electromechanical equipment usually refers to the general term for machinery, electrical appliances and electrical automation equipment. In the field of construction, they are the general term for machinery and piping equipment other than geotechnical, carpentry, steel bars, mud and water, etc. During the installation of electromechanical equipment, it is necessary to connect the various components through welding.

[0003] In the prior art, when it is necessary to weld electromechanical equipment, the welding gun needs to be moved flexibly to perform welding work on different welding locations. The first motor is started, and the first screw rod fixedly installed at its output end rotates accordingly. Since the first set of plates slides with the outer wall of the first limit rod, under its restriction, the rotating first screw rod drives the first set of plates to move longitudinally, so that the second motor fixedly installed on the top of the first set of plates moves accordingly, so as to drive the welding straight pipe slidingly arranged inside the second set of plates to move longitudinally, so that the welding straight pipe drives the welding gun to move longitudinally for welding. The second motor is started, and the second screw rod fixedly installed at its output end rotates accordingly. Since the second set of plates slides with the outer wall of the second limit rod, under its restriction, the second screw rod can drive the second set of plates to move horizontally, so that it drives the welding gun to perform horizontal welding work. This structure allows the welding gun to weld flexibly.

[0041] The longitudinal moving mechanism 14 is connected to the moving frame 2 and is used to drive the welding mechanism 10 to move longitudinally.

[0042] The present invention uses a first arc frame 3 and two second arc frames 5 that can be matched. When the welding mechanism 10 needs to perform mobile welding, the two second arc frames 5 will rotate to the two sides of the first arc frame 3 under the action of the closing mechanism 11, so that the welding mechanism 10 at the bottom of the first arc frame 3 is exposed, and flexible mobile welding is performed in cooperation with the horizontal moving mechanism 15 and the longitudinal moving mechanism 14.

Welding, and when the welding mechanism 10 needs to perform annular mobile welding, under the action of the closing mechanism 11, the two second arc frames 5 rotate in the opposite direction until they are closed, and form an annular structure composed of the first arc frame 3 and the two second arc frames 5, wherein the first arc slide 4 and the two second arc slides 6 also form an annular structure, and are slidably connected with the arc guide rail 8, so that the above-mentioned annular structure can be driven to rotate by the driving mechanism 12, so that the welding mechanism 10 can perform annular welding. The present invention can realize horizontal and vertical mobile welding and annular welding through the first arc frame 3 and the two second arc frames 5 and the corresponding structure, and the welding state can be flexibly converted, thereby improving the practicality of the entire welding equipment.

[0043] In one case of this embodiment, the welding mechanism 10 includes a welding frame 1001 installed on the first arc frame 3 and the second arc frame 5, and a first telescopic member 1002 is installed on the welding frame 1001. Preferably, the first telescopic member 1002 is configured as a hydraulic rod, and the first telescopic member 1002 is fixedly connected to a lifting plate 1003, and the lifting plate 1003 is fixedly connected to a welding gun 1004.

[0044] During welding, the welding height of the welding gun 1004 is adjusted by the third telescopic member 16, and then the installation welding position of the welding gun 1004 on the electromechanical equipment is adjusted under the drive of the transverse moving mechanism 15 and the longitudinal moving mechanism 14. In addition, the first telescopic member 1002 in this embodiment can fine-tune the position of the welding gun 1004.

[0045] In one case of the present embodiment, the closing mechanism 11 includes a transmission frame 1101, which is connected to the first arc frame 3 through a fixed frame 1102. Two transmission shafts 1103 are rotatably provided in the middle of the transmission frame 1101. The connecting shaft 7 and the transmission shaft 1103 are both provided with transmission wheels 1104 located in the transmission frame 1101. The two transmission wheels 1104 are connected to each other through a synchronous belt 1105. The two transmission shafts 1103 are provided with first gears 1106 that mesh with each other. A first driving member 1107 connected to one of the transmission shafts 1103 is provided on the outer wall of the transmission frame 1101. Preferably, the first driving member 1107 is provided as a servo motor. A plurality of guide wheels 1108 in contact with the synchronous belt 1105 are rotatably provided in the transmission frame 1101.

[0046] In this embodiment, when it is necessary to close the first arc frame 3 and the two second arc frames 5 to form an annular structure, the first driving member 1107 is started through the external controller, and the first driving member 1107 drives the transmission shaft 1103 connected thereto to rotate, and drives the other transmission shaft 1103 to rotate through the mutually meshing first gear 1106, and then cooperates with the synchronous belt 1105 and the transmission wheel 1104 to simultaneously drive the connecting shaft 7 on both sides of the first arc frame 3 to rotate, so that the two second arc frames 5 rotate downward until they are closed, and form an annular structure with the first arc frame 3, and at the same time, the first arc slider 4 and the second arc slider 6 on the first arc frame 3 and the second arc frame 5 are also closed, so that it is convenient for the driving mechanism 12 to drive the above-mentioned annular structure to rotate, and then the welding mechanism 10 can be driven to move in an annular manner to achieve annular welding.

[0047] In addition, due to the structural characteristics of the first arc frame 3 and the two second arc frames 5, when the welding mechanism 10 welds the annular connection of the electromechanical equipment, the entire device can be moved above the electromechanical equipment, and the first arc frame 3 is located above the annular connection, and then the two second arc frames 5 are closed by the closing mechanism 11, so as to facilitate the welding mechanism 10 to perform annular welding on the annular connection, and after the welding is completed, the two second arc frames 5 can be separated to facilitate the rapid separation of the equipment from the electromechanical equipment, and the use effect is better.

[0048] In one case of the present embodiment, the driving mechanism 12 includes a first incomplete internal gear ring 1201 installed on the inner wall of the first arc frame 3, a second incomplete internal gear ring 1202 is installed on the inner wall of the second arc frame 5, a driving shaft 1204 is rotatably arranged at the bottom of the movable frame 2, a second gear 1205 which can mesh with the first incomplete internal gear ring 1201 and the second incomplete internal gear ring 1202 is installed on the driving shaft 1204, and a second driving member 1203 connected to the driving shaft 1204 is installed at the bottom of the movable frame 2. Preferably, the second driving member 1203 is configured as a servo motor.

[0049] In this embodiment, when the first arc frame 3 and the two second arc frames 5 are closed to form an annular structure, the second driving member 1203 is started by an external controller to drive the driving shaft 1204 to rotate, and the driving shaft 1204 drives the second gear 1205 to rotate. The first incomplete inner gear ring 1201 meshing with the second gear 1205 can drive the first arc slider 4 on the first arc frame 3 to slide along the arc guide rail 8, so that the above-mentioned annular structure rotates, and because the first arc frame 3 and the two second arc frames 5 are closed, the first incomplete inner gear ring 1201 and the two second incomplete inner gear rings 1202 form a complete inner gear ring, so that the above-mentioned annular structure can be continuously driven to rotate, thereby driving the welding mechanism 10 to perform annular welding.

[0050] In one case of this embodiment, the limiting mechanism 13 includes a slot 1301 opened on the fixed frame 1102 and a block 1302 cooperating with the slot 1301, the block 1302 is fixedly connected to the limiting frame 1303, the limiting frame 1303 is connected to the movable frame 2 through the second telescopic member 1304, preferably, the second telescopic member 1304 is configured as a hydraulic rod, and the movable frame 2 is provided with a limiting rod 1305 slidably connected to the limiting frame 1303, and a stop block 1306 is installed at the end of the limiting rod 1305 away from the movable frame 2.

[0051] In this embodiment, when the welding mechanism 10 does not need to perform circular welding, in order to prevent the first arc frame 3 from rotating, the second telescopic member 1304 is started by an external controller, and the second telescopic member 1304 extends to push the limit frame 1303 close to the fixed frame 1102, so that the block 1302 on the limit frame 1303 is inserted into the slot 1301 of the fixed frame 1102, thereby limiting the first arc frame 3 and preventing the first arc frame 3 from moving abnormally and affecting the precise welding of the welding mechanism 10.

[0052] In one case of this embodiment, the longitudinal moving mechanism 14 includes a longitudinal frame 1401, a first screw 1402 is rotatably arranged inside the longitudinal frame 1401, the first screw 1402 is threadedly connected to the moving frame 2, a longitudinal rod 1403 is provided inside the longitudinal frame 1401 and is slidably connected to the moving frame 2, and a third driving member 1404 connected to the first screw 1402 is installed on the outer wall of the longitudinal frame 1401. Preferably, the third driving member 1404 is configured as a servo motor.

[0053] In this embodiment, the third driving member 1404 is started by an external controller, and the third driving member 1404 drives the first screw rod 1402 to rotate. The rotation of the first screw rod 1402 drives the movable frame 2 to move along the longitudinal rod 1403, thereby realizing the longitudinal movement of the welding mechanism 10.

[0054] In one case of this embodiment, the transverse moving mechanism 15 includes a transverse frame 1501 installed on the fixed frame 1, a second screw 1502 is rotatably arranged in the transverse frame 1501, the second screw 1502 is slidably connected to the longitudinal frame 1401, a transverse rod 1503 is arranged in the transverse frame 1501 and is slidably connected to the longitudinal frame 1401, and a fourth driving member 1504 connected to the second screw 1502 is installed on the outer wall of the transverse frame 1501.

[0055] In this embodiment, the fourth driving member 1504 is started by an external controller, and the fourth driving member 1504 drives the second screw rod 1502 to rotate. The rotation of the second screw rod 1502 drives the longitudinal frame 1401 to move along the transverse rod 1503, thereby realizing the transverse movement of the welding mechanism 10.

[0056] The present invention uses a first arc frame 3 and two second arc frames 5 that can be matched. When the welding mechanism 10 needs to perform mobile welding, the two second arc frames 5 will rotate to the two sides of the first arc frame 3 under the action of the closing mechanism 11, so that the welding mechanism 10 at the bottom of the first arc frame 3 is exposed, and the lateral moving mechanism 15 and the longitudinal moving mechanism 14 are cooperated to perform flexible mobile welding.
