Synchronous transporting device of double trolley

Abstract

The invention discloses a synchronous transporting device of a double trolley. The transporting device comprises two self-propelled trolleys transporter (1), a left rail (2), a right rail (5) and an electronic control cabinet (9). The two self-propelled trolleys transporting device(1)are hung respectively on the left rail (2) and the right rail (5). Each self-propelled trolley transporting device comprises a trolley (11), a chain hoist (12), a shear mode balance mechanism (13) and a lifting appliance (14). The trolley (11), the chain hoist (12), shear mode balance mechanism (13) and the lifting appliance (14) are connected successively. The electronic control cabinet (9) is provided with a programmable logic controller (PLC) which is connected with the two self-propelled trolleys transporting (1) to form an electric control loop through a wire (8). The transporting device has the advantages of being small in weight, small in inertia, high in locating precision, little in auxiliary time, safe and reliable, low in cost, convenient to maintain and long in service life, being capable of adapting to quick-beat transportation and being applied to pretreatment electrophoresis transporting device of a large-scale workpiece.

Description

Technical field: [0001] The invention relates to a conveying machine, in particular to a synchronous conveying device for double trolleys. Background technique: [0002] In the existing automobile production line, for the pre-treatment electrophoresis transportation of large workpieces with a length of more than 10 meters such as the frame, a large-scale program-controlled crane is used for horizontal transportation. There are several problems in the following aspects when using program-controlled truck transportation: First, Due to the large span of the program-controlled train, the dead weight generally exceeds 10 tons, so when moving, the inertia is large, the precise stop takes a long time, and the strength of the steel structure and track of the factory building is high; secondly, the seamless connection of the program-controlled train track is difficult; Third, it needs to be equipped with a secondary transfer spreader, which increases the transfer time, and there is a...

[0002] In the existing automobile production line, for the pre-treatment electrophoresis transportation of large workpieces with a length of more than 10 meters such as the frame, a large-scale program-controlled crane is used for horizontal transportation. There are several problems in the following aspects when using program-controlled truck transportation: First, Due to the large span of the program-controlled train, the dead weight generally exceeds 10 tons, so when moving, the inertia is large, the precise stop takes a long time, and the strength of the steel structure and track of the factory building is high; secondly, the seamless connection of the program-controlled train track is difficult; Third, it needs to be equipped with a secondary transfer spreader, which increases the transfer time, and there is a problem that the secondary spreader returns to the transportation; fourth, it cannot adapt to the fast-paced transportation task; fifth, the cost is expensive and the maintenance cost is high
