Detailed Description
Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
A plate conveying and positioning device for a crane girder welding production line comprises a plurality of RGV trolleys arranged on a pair of floor guide rails 1. A pair of floor rails 1 are extended from a plate blanking area to a main beam welding area, and an RGV is used for conveying plates. Because the length of hoist girder plate is big, consequently, need a plurality of RGV dollies to bear the plate jointly, prevent plate bending deformation.
As shown in fig. 1, the RGV car includes a base 2 moving longitudinally along a floor rail 1, a transverse rail is provided on the base 2, and a pair of support frames 3 for supporting the panel are slidably connected to the transverse rail. In order to reduce the friction between the plate and the support frame 3, the technical scheme is further improved, a plurality of universal balls 9 are arranged on the support frame 3, and the support frame 3 supports the plate through the universal balls 9, so that the plate can roll on the universal balls 9.
As shown in fig. 2, due to the different widths of the plates, in order to stably support the plates, a technical solution is further improved, a pair of support frames 3 are connected through a double-rotation-direction screw 10, a third motor 11 is arranged on the base 2, and the third motor 11 is connected with the double-rotation-direction screw 10 through a gear reduction mechanism. When the third motor 11 rotates, the pair of support frames 3 approach to each other or move away from each other in the opposite direction, so that the support width of the plate member can be adjusted.
As shown in fig. 3, the RGV car further includes a pair of telescopic push rods 4 transversely disposed, and the pair of telescopic push rods 4 is connected with a first motor 5 through a gear-rack kinematic pair. When the first motor 5 rotates, the pair of telescopic push rods 4 simultaneously contract inwards at equal intervals, so that the push plates 4.1 at the outer ends of the telescopic push rods 4 are clamped on two sides of the plate. A pair of telescopic push rods 4 simultaneously contract inwards at equal intervals, so that the length direction of the plate is parallel to the floor guide rail 1, and the placement position of the plate is relatively fixed to the floor guide rail 1, so that the plate is positioned during assembly welding.
During welding, the push plate 4.1 can obstruct the assembly and welding of the plates. According to the further improved technical scheme, a lifting shaft 12 which is vertically arranged is connected below the pair of telescopic push rods 4, and the lifting shaft 12 is connected with a fourth motor 13 through a gear rack kinematic pair. When the fourth motor 13 rotates, the lifting shaft 12 drives the pair of telescopic push rods 4 to move downwards, so that the push plate 4.1 is separated from the plate, and a welding area is made. Similarly, when the plate is positioned, the lifting shaft 12 drives the pair of telescopic push rods 4 to move upwards, so that the push plates 4.1 can be clamped on two sides of the plate.
As shown in fig. 4 and 5, in order to reduce the resistance of the base 2 to travel on the floor rail 1 and improve the positioning accuracy, the technical solution is further improved, the floor rail 1 is an i-shaped rail, the base 2 is provided with a plurality of wheel seats 14, each wheel seat 14 is provided with a support roller 14.1 in rolling contact with the upper top surface of the i-shaped rail, and a pair of side rollers 14.2 in rolling contact with the two side surfaces of the i-shaped rail are further provided.
The base 2 is provided with a second motor 6, the second motor 6 is connected with a walking gear 7, and the walking gear 7 is meshed with a long rack 8 arranged on one side of the floor guide rail 1. The second motor 6 drives the base 2 to walk along the floor guide rail 1, so that the plate is conveyed and positioned.
