When the precast pile with the end plate is welded, a welder holds an arc welding tongs or a carbon dioxide gas shielded welding gun to manually weld the V-shaped grooves spliced by the 2 end plates, the labor intensity is high, the welding quality is unstable, the welding efficiency is low, and the body health of the welder is influenced by the emission of waste gas. In order to achieve the welding strength and the height of a welding seam, the welding is required to be carried out for more than 3 times, and manual slag removal is required before each welding, so that the phenomena of material stealing and material reduction, and opportunity investment and skillful operation are frequently caused; the welding robot for the precast pile splicing can automatically weld through a set program, can ensure automatic welding of the V-shaped grooves spliced by the 2 end plates due to advanced structure and superior performance, has high welding speed, uniformity and stability and excellent quality, can completely achieve the required welding seam height and welding strength without slag removal.
The invention will be further described with reference to the following figures and examples.
As shown in fig. 1-2, a welding robot for precast piling includes:
the bottom has the removal shallow 2 of 4 rubber wheels 1, can reach quick safe purpose when using or withdrawing the transfer, because the welding robot who is used for the precast pile extension is very light, just only lays the carpenter's board on ground and just can promote to remove shallow 2 and advance on the carpenter's board. The tray 3 is arranged on a chassis of the movable trolley 2, the annular rail 7 is arranged on the upper plane of the tray 3, the welding trolley 8 is arranged on the annular rail 7 on the upper plane of the tray, and the welding manipulator 8-1 is connected in the annular rail 7 in a sliding mode through the welding trolley 2. The welding manipulator 8-1 and the welding trolley 8 are both in control connection with the controller, the tray 3 is of a hollow structure, the annular rail 7 surrounds the hollow structure, the hollow structure of the tray 3 surrounds the welding groove on the outer edge of an end plate or a hoop of a precast pile when the precast pile is connected, and a clamping mechanism for firmly pressing the precast pile is arranged below the tray 3. The welding trolley 8, the electric telescopic wall of the welding manipulator 8-1, the driving of the manipulator and the welding gun are electrically connected with the controller, and the controller controls the welding of the welding manipulator 8-1 and controls the transmission of the welding trolley 8. The welding carriage 8 can be an electrically controlled carriage.
The clamping mechanism for firmly pressing the precast pile comprises a hydraulic jack 4 which is horizontally installed, the number of the hydraulic jack 4 is a plurality of, preferably 4, the hydraulic jack 4 uniformly surrounds the precast pile, a pressing plate 5 is arranged at the end part of the hydraulic jack 4, a rubber plate 6 is installed on the end face of the pressing plate 5, the rubber plate 6 faces the precast pile to be firmly pressed, and the hydraulic jack 4 is in control connection with a controller. The rubber sheet 6 can increase the friction force when the precast pile is pressed firmly. Therefore, the precast pile can be compressed through stroke adjustment of a piston rod of the hydraulic jack 4 according to different specifications of the precast pile, and the whole trolley used as a welding robot rack is positioned and fixed.
A chassis 13 fixed on the frame of the cart 2 is arranged below the tray 3, the chassis 13 is parallel to the tray 3, and the chassis 13 is connected with a horizontal fine adjustment device which can ensure the horizontal state of the tray 3.
The horizontal fine-adjustment device comprises 3 worm and gear boxes and 3 lead screws which are vertically fixed on the chassis 13, and the worm and gear boxes 9 correspond to the lead screws 14 one by one. The worm and gear box 9 is in control connection with the controller, so that the controller receives signals of the level sensor, and the levelness of the tray 3 can be adjusted by automatically screwing the lead screw 14 through the worm and gear box 9. The hydraulic jack 4 is connected with the chassis 13 through a fixed support.
A level sensor is also mounted on the chassis 13. The level sensor is in control connection with the controller, so that the levelness of the tray 3 can be automatically adjusted by driving the lead screw 14 through the worm and worm gear box 9 according to the level sensor, and the problem that the chassis 13 and the tray 3 are prone to being inclined when a welding robot for precast pile splicing is placed on uneven ground is solved.
Tray 3 with connect through 14 elevating system of lead screw between the chassis 13, elevating system includes the worm gear case 9 of vertical setting, worm gear case 9 with controller control connection, the bottom of worm gear case 9 is linked firmly on the chassis 13, the top of the lead screw 14 that worm gear case 9 corresponds is connected the bottom of tray 3.
